Product Description: Meihuan Customized Conveyor Belt Cleaning Box – Belt Cleaning EquipmentFriendly reminder: Image and price descriptions are for reference only. For details, please contact us. Thank you.The cleaning box is installed at the head of the conveyor belt and mainly consists of the box body, cleaner, pressure roller, spray device, drying device, cleaning device, discharge device, and liquid supply device. When the return belt passes through the cleaning box, the cleaning device sprays mist onto the working surface of the return belt. A specialized independent shock-absorbing dual-blade cleaner scrapes off the coal dust mixed with the mist, and then a polyurethane cleaner removes the remaining water. The scraped coal dust and water are discharged through a specially designed chute into the auxiliary chute at the head of the existing conveyor belt, entering the downstream belt. To ensure cleaning effectiveness, two sets of pressure rollers are installed at the top of the cleaning box, along with an air configuration to prevent excessive accumulation of scraped coal dust, which could cause material blockage. Additionally, to meet winter usage requirements, the liquid used in the cleaning box can be either water or antifreeze.The implementation of the Meihuan cleaning box has shown significant cleaning results, markedly reducing coal accumulation at the conveyor belt head and lowering belt cleaning costs.Introduction to the Conveyor Belt Cleaning Water TankThe cleaning box (i.e., the conveyor belt washing device) is designed to remove materials adhering to the working surface of the conveyor belt, preventing material buildup on the lower rollers that could cause belt misalignment, spillage, dust generation, and hard-to-remove ground accumulations, thereby polluting the working environment.Working PrincipleThe cleaning box consists of three parts: the spray system, cleaning system, and drying system. When the return belt enters the cleaning box, the idler and pressure rollers work together to ensure the cleaner scrapes material without shaking or damaging the belt. First, high-pressure water mist softens the caked material on the belt surface. The initial stage uses a softened tungsten steel cleaner to remove coarse material, the second stage employs a water-removing cleaner to scrape off moisture, and the third stage uses a fine material cleaner to remove residual fine powder. Finally, the belt is dried with room-temperature high-pressure air before exiting the box.Product Features1. Water lubrication significantly reduces friction and temperature between the blades and the belt, effectively extending the belt's service life.2. The cleaning box is equipped with well-performing observation doors for easy inspection and maintenance.3. A remote electrical control box is installed beside the unit, automatically interconnecting with the main machine. The cleaning system operates synchronously with the belt.4. The cleaning box consumes approximately S tons of water per day. Water flows through a funnel into a small storage tank beside the machine and is continuously recirculated to the spray system via a frequency-conversion booster pump, saving significant manpower and resources while achieving the environmental goal of wastewater recycling and reuse.5. Hopper spray system: Washes the discharge hopper to prevent scraped material from clogging the hopper. more>

Product Description: Cleaning Box Conveyor Belt Cleaning Device Customized by MeihuanFriendly reminder; images, prices, and descriptions are for reference only. For details, please contact us. Thank you.Product Overview of Belt Cleaning BoxThe belt cleaning box integrates multiple functions such as a spraying system, material cleaning system, belt drying, material recovery, and remote control into one cleaning device. It thoroughly solves the environmental pollution caused by material carryback on the return belt and the issue of belt misalignment caused by residual material adhering to idlers, thereby improving the on-site environment.I. Functions of the Cleaning Box:1: Belt Stabilization System: The cleaning box features a unique belt stabilization system that ensures the belt enters and exits the device smoothly.2: Spraying System: The cleaning box first softens and cleans the adhered material on the conveyor belt, making it easier to proceed to the next step.3:Cleaning System: After the material is softened by the spraying system, it enters a specially designed combination cleaner to remove stubborn material first, followed by fine material, thereby effectively clearing adhered substances. The cleaning, material removal, and water removal blades feature automatic compensation and self-advancing performance.4: Drying System: Since the cleaning box operates with water, residual moisture may remain on the belt. The drying system of our cleaning box effectively removes residual moisture, achieving a belt cleanliness of over 85%.5;Drainage System: The cleaning box's unique drainage system allows the cleaned material to be discharged smoothly from the device to a designated location without causing ground pollution.6;Control System: The control box enables fully automated operation of the device and ensures synchronization with the on-site conveyor belt.II. Components of the Cleaning Box:Cleaning box body, solenoid valve, filter, pressure pump, control box, connecting flanges (installation flange, drainage flange), and wiring.Note: The original water-removal cleaner material was ordinary polyurethane, with a service life of about 2 months, after which it lost its effectiveness. The current device uses carbide material for the water-removal cleaner, which has a longer service life, a 12-month warranty, and does not damage the belt. more>

Product Description: Currently, urban bus fare collection boxes do not provide change and cannot verify the authenticity of coins. For buses that handle a massive daily flow of passengers, this payment method is highly inconvenient. Additionally, at cash counting centers, staff repeatedly sort and organize loose change. Almost every fare box contains "problem" coins, including counterfeit one-yuan coins, damaged coins, and game tokens. Every day, they must sift through vast amounts of loose change to remove these problematic, damaged, and counterfeit coins, and then repair the damaged ones. The workload is enormous, making the entire coin collection and processing system for public transportation extremely cumbersome. This not only hinders the development of urban public transport but also causes significant inconvenience to citizens' travel.Guolang's intelligent fare collection box offers improvements over existing technology: it features automatic counterfeit detection and smart counting capabilities. Integrated with a system processing motherboard, it packages functions such as automatic counterfeit detection, smart counting, real-time data uploads, and real-time coin drop positioning into the bus fare box. This addresses the current challenges of inability to verify authenticity and lack of real-time data monitoring. It enables controllable, traceable, countable, and counterfeit-eliminating technical processing of fare transaction data. To some extent, it prevents losses for public transport companies, greatly facilitates passenger travel, alleviates the workload for cash counters, and fosters an atmosphere of integrity and civilized travel in society.

The busbar chambers between switchgear cabinets should be isolated with insulating barriers and insulating sleeves.2. Each section of the busbar is selected based on long-term allowable current-carrying capacity and can withstand the electromagnetic force generated by the closing current of the circuit breaker connected to the busbar. The busbars in the busbar chamber are insulated, and the busbar joints should be silver-plated.3. The main busbar and branch busbar have identifiable markings.4. The minimum cross-section of the grounding main busbar complies with specifications and power supply bureau requirements.Secondary part technical requirements, general requirements:1. The low-voltage chamber should include: lighting lamps, miniature circuit breakers, terminals, secondary wiring, and small busbars for interconnection between cabinets.2. Protection for control and closing DC secondary circuits uses imported or joint-venture brand DC miniature circuit breakers, with communication interfaces connected to the computer monitoring system.3.
