Product Description: Greenhouse meat duck farming technology is a common method for raising meat ducks. Utilizing greenhouse farming effectively can enhance the profitability of meat duck production. However, building a greenhouse requires certain skills, and there are specific techniques involved in raising ducks in greenhouses. How to build a greenhouse for meat duck farming: 1. Site selection and construction: The greenhouse for large-scale duck farming should be built in a location that is sheltered from the wind, sunny, well-drained, conveniently accessible, close to a water source, and situated on high, dry ground. To maximize the use of solar energy, the orientation should ideally face east-west. The shed should be arched, with a height of at least 2 meters, and the length and width should be determined based on the scale of farming. Use welded pipes with a diameter of 25 mm and a wall thickness of 1.35 mm, bent into a semi-circular shape as supports, with two pipes forming one set, secured with sleeves of 30 mm diameter and 1.5 mm wall thickness. During construction, after installing the supports according to specifications, fix the brackets on each support tightly with wooden sticks or steel pipes, then secure the support net with bamboo poles and steel wires in 3 to 5 rows, with one column every 2 to 4 meters. Once the frame is built, first lay straw mats on top, cover the straw mats with plastic film, and then cover the plastic film with 70% to 80% sunshade netting. Use cables to secure the shed tightly along its length, making it easy to roll up for sunlight exposure. It is important to note that movable doors should be installed at both ends of the greenhouse.The greenhouse for large-scale duck farming should be built in a location that is sheltered from the wind, sunny, well-drained, conveniently accessible, close to a water source, and situated on high, dry ground.

Product Description: The pulverized coal distributor is a key equipment in the blast furnace coal injection system of steel plants, responsible for evenly distributing pulverized coal to the blast furnace tuyeres. Below is a detailed introduction: - **Structural Features**: The new type of pulverized coal distributor is typically a conical cavity container, with distribution branch pipes proportionally and evenly arranged on the upper side of the cavity container, forming a 90-degree right angle or 120-degree angle with the diagonal branch pipes of the distributor cavity container. Its outlets can be divided into 6-35 pipes, with pipe diameters including 15, 20, 25, and others. The branch pipe connection methods include flange type, butt weld threaded type, and butt weld type. - **Working Principle**: Pulverized coal enters the inner cavity of the distributor from the conveying pipeline. Due to the sudden increase in volume, utilizing gas dynamics principles, the pulverized coal evenly enters each distributor branch pipe. For example, in a conical distributor, the total outlet area of the branch pipes is similar to the inlet channel area. When a high-pressure solid-gas flow enters the inner cavity, it forms a strong vortex that envelops the pulverized coal and then evenly distributes it to each branch pipe. - **Performance Parameters**: Suitable medium is dry pulverized coal, operating temperature ≤80°C, operating pressure 1.6MPa-2.5MPa, distribution error ≤5%. - **Product Advantages**: The pulverized coal distributor can evenly distribute the pulverized coal passing through the pipeline, ensuring full and stable combustion in the burner, thereby saving energy and reducing environmental pollution. At the same time, it also offers advantages such as safe and reliable operation and a long service life. - **Installation Method**: The distributor can be installed on the tuyere platform, mounted via connecting flanges at the upper end of the vertical pulverized coal main pipe. The vertical section height only requires 2-3m, and by reasonably arranging the pipeline direction, uniform distribution of pulverized coal can be achieved. - **Wear-Resistant Design**: To extend the service life of the distributor, various wear-resistant materials are used, such as wear-resistant hardfacing on the cone, hard alloy pipe heads embedded at the branch pipe inlets, or wear-resistant ceramic linings. more>

Company: Wuxi Mingxun Forklift Co., Ltd.

Product Description: Common Classifications of Suzhou BYD Electric ForkliftsJiangsu BYD Electric Forklift General Agent: 158 5280 5975 Manager ZhuPallet ForkliftPallet forklifts feature a compact structure and flexible operation, available in manual and electric versions. They are mainly used for horizontal transportation in production lines and warehouses. Due to their small size, they can operate in narrow spaces.Stacker ForkliftStacker forklifts are similar to pallet forklifts, but they are equipped with lifting devices, allowing for the handling, stacking, and short-distance transportation of palletized goods.Stacker forklifts are similar to pallet forklifts, but they are equipped with lifting devices, enabling the handling, stacking, and short-distance transportation of palletized goods. They are primarily used for the rapid lifting, stacking, and storage of lightweight goods on flat surfaces, with a lifting height of up to 5 meters.Counterbalanced ForkliftCounterbalanced forklifts are the most widely used type of forklift. The forks are located outside the centerline of the front wheels, and the rear of the forklift is equipped with a counterweight. They are currently available in internal combustion and electric versions. Internal combustion forklifts account for 80% of the market share, offering sufficient power and long operating times. However, they are noisy and polluting. Electric forklifts are generally used for indoor work, featuring low noise and no pollution, making them widely applicable for handling goods such as cold storage foods.Reach ForkliftReach electric forklifts are a type of warehouse vehicle, categorized by operation into seated reach and stand-up reach models. Reach forklifts have a relatively small lifting capacity and are often electrically driven. Electric reach forklifts are characterized by their flexibility, ease of operation, no pollution, and low noise.Order Picker ForkliftOrder picker forklifts, also known as picking forklifts, consist mainly of a lifting system, body system, and electrical system. The operator can ride on the platform to handle materials, facilitating easy picking at various heights. Order picker forklifts have a lifting height of 4 to 6 meters and are suitable for narrow aisles and high-level warehouse racks.Rough Terrain ForkliftRough terrain forklifts, also known as all-terrain forklifts, are specialized vehicles with strong off-road capabilities, suitable for handling and transporting goods in areas with poor road conditions. They feature strong off-road performance, mobility, and reliability. Rough terrain forklifts are generally powered by internal combustion diesel engines, which provide high torque, thermal efficiency, and power while emitting significantly fewer harmful gases than gasoline engines, making them relatively environmentally friendly.Heavy-Duty ForkliftHeavy-duty forklifts, as the name suggests, have a strong rated load capacity, with a lifting capacity of over 13 tons. Heavy-duty forklifts, container forklifts, and container stackers all fall under this category. They are less commonly used in daily applications and are generally employed in heavy industries and port container handling and stacking.Telescopic Handler ForkliftTelescopic handler forklifts are equipped with extendable booms, with forks or attachments usually mounted on the boom, enabling lifting or fork handling operations. These forklifts can perform fork handling across obstacles or openings and handle multi-row stacking and destacking in complex working conditions. Telescopic handler forklifts offer good forward visibility and have lower requirements for aisle clearance height. They are sometimes classified as rough terrain forklifts.Currently, forklifts can be broadly categorized into these 8 types. The production and application of forklifts have greatly liberated labor and improved production efficiency. Major international forklift manufacturers are now introducing new concept vehicles, and it is believed that future forklift development will focus on greater environmental friendliness and intelligence.Source: Internet.

Company: Shaanxi Deli Energy Technology Co., Ltd.

Product Description: After the steam generator is ignited normally, the temperature should be raised slowly to ensure uniform expansion of the furnace walls and the furnace body. The process from ignition under cold conditions to reaching the working pressure should generally be controlled within 3 to 4 hours. When the steam pressure rises to 0.06~0.1MPa, the pressure gauge and water level gauge of the steam generator should be flushed to maintain their normal operation. When the boiler steam pressure reaches 0.15~0.2MPa, close the air valve and check whether the safety valve is leaking. If there is any leakage, immediate measures should be taken to eliminate it. When the boiler pressure rises to 0.2~0.25MPa, perform a blowdown of the boiler drum. During the blowdown of the steam generator, the boiler water level should be at the highest water level line. After blowdown, check whether the blowdown valve is tightly closed and if there is any leakage. When the steam pressure reaches 0.3MPa, conduct a comprehensive inspection of the fasteners of the pressure-bearing components of the steam generator, such as manholes, handholes, inspection holes, and bolts of various flanges, and perform a thermal tightening. When the boiler steam pressure reaches the working pressure, adjust the safety valve. During the boiler pressure-raising process, the top vent valve should be frequently opened to avoid air accumulation and reduce boiler corrosion.Boiler Steam (Heat) SupplyThe maximum water temperature of the boiler should be lower than the saturation temperature under the network pressure minus 20°C. For intermittently supplied hot water boilers, the circulation pump should continue to operate during the intermittent periods. more>

Product Description: Marble platforms and marble plates have uniform texture, good stability, high strength, and hardness, maintaining high precision under heavy loads. They are suitable for measurement tasks in industrial production and laboratories. Although marble platforms and marble plates are harder than cast iron, during inspection and testing processes, relative movement and friction with the products being inspected can cause wear. Since the products typically inspected or tested using marble platforms require very high precision, the accuracy requirements for marble platforms and marble plates are also very high. If the flatness of the marble platform or marble plate exceeds the tolerance, it cannot guarantee the accuracy and correctness of the inspection and testing results. Therefore, when the flatness of marble plates or marble platforms exceeds the tolerance, they need to be repaired, maintained, and calibrated. Manual grinding is used to restore the flatness of marble plates and marble platforms to meet the required flatness grade and work needs.Botou Linuo Measuring Tools Co., Ltd. is a manufacturer engaged in the production, processing, sales, and grinding repair of marble platforms. We provide users with high-quality marble plates, marble platforms, and marble measuring tools, and undertake marble platform repair, marble plate repair, and marble platform grinding repair services.

Product Description:       To improve extraction efficiency and shorten the leaching time of tea's active components, high-temperature water extraction is generally used in tea extraction. Under specific conditions of temperature, time, and stirring, active components such as tea polysaccharides, tea polyphenols, and trace elements are leached from the tea leaves. The clarity of the extracted tea broth is not high due to the simultaneous leaching of pectin, fibers, and other impurities, thus further clarification and impurity removal are required. The concentrated tea juice commonly purchased online is a high-concentration product obtained by concentrating the extraction liquid. Using our company's instant tea powder production line in Yunnan Pu'er as an example, this article explains the domestic processes of tea extraction, filtration, and concentration for those who need to understand and learn.      Traditional tea extraction processes involve coarse filtration using plate and frame filters or diatomaceous earth after extraction, followed by thin-film evaporation or other vacuum concentration methods to obtain concentrated tea liquid. However, the resulting tea liquid has poor clarity and low purity. Thin-film thermal evaporation damages the components of the material, resulting in poor taste, and the energy consumption for concentration is high. Generally, evaporating one ton of water requires 0.8–1 ton of steam, meaning the dehydration cost ranges between 260–300 RMB.       Currently, tea extraction production lines incorporate advanced membrane separation technology to improve quality and achieve energy savings and consumption reduction. For example, the production process of an instant tea powder production line for a Pu'er tea company client is as follows:      Tea extraction → Centrifugation → Ceramic membrane filtration → Nanofiltration membrane concentration → Vacuum concentration → Drying      Tea liquid has complex components and high requirements for product flavor. Using ceramic membrane filtration combined with nanofiltration membrane concentration to replace traditional thin-film evaporation processes can remove impurities such as colloids, large-molecule杂proteins, and fibers from the extraction liquid while preserving the active components of the tea liquid. This achieves physical clarification and purification. The filtrate entering the nanofiltration membrane system can enhance component concentration and yield. While maintaining the original flavor of the tea liquid, energy consumption is significantly reduced. Generally, the energy cost for membrane concentration to remove one ton of water is between 8–15 RMB. Treating 20 tons of tea liquid with nanofiltration membrane technology can yield approximately 2.5 tons of concentrated liquid at 15% concentration. If the concentration requirement is not met, further vacuum concentration with a smaller scale is selected. The powder obtained after drying the concentrated liquid has good dispersibility, high purity, dissolves quickly in water, and exhibits high clarity.       For more inquiries about Tea Deep Processing Extraction Technology and Equipment, please contact Zhang Gong from Chongqing Jiahe Filtration Technology Co., Ltd. I will provide tailored solutions based on your specific needs. Friends are also welcome to visit our company to see the actual equipment or conduct on-site samples to observe the separation effects. more>
