Product Description: A flameless explosion venting device is a safety apparatus used to protect equipment and personnel. It automatically shuts down equipment or pipelines in the event of an explosion or fire to prevent the spread of flames or the escalation of an explosion. Its working principle involves detecting changes in gas pressure and temperature inside the pipeline or equipment to determine whether there is a risk of explosion or fire. If a hazard is confirmed, the device or pipeline is immediately shut down while releasing pressure to achieve the goal of protecting both equipment and personnel.Dust Collector Flameless Explosion Vent Valve (Flame Arresting Safety Equipment)Brief Introduction:1. It consists of two parts: an explosion vent panel and a flame extinguishing module;2. Suitable for flameless venting of dust explosions in indoor equipment. It offers high venting efficiency and is cost-effective;3. Effectively blocks flames and heat, providing a safe environment for equipment, buildings, and personnel. It also collects dust effectively, reducing environmental pollution;4. When used in combination with an isolation valve, it not only prevents pressure waves and flames from propagating to upstream workshop areas but also suppresses secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static opening pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame arrestor material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg*m/s, with effective venting area meeting explosion venting requirements;Product classification: Depending on the application, it can be divided into rectangular flameless explosion venting devices and curved flameless explosion venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors;Industries: Wood processing, plastics, spraying, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Dust Collector Flameless Explosion Vent Valve (Flame Arresting Safety Equipment)Working Principle:The flameless venting device consists of two parts—an explosion vent panel and a flame extinguishing module. The explosion vent panel responds to the rapid increase in deflagration pressure, opening immediately to reduce pressure. When the expanding fireball passes through the open vent panel, it is intercepted by the flame extinguishing module. The precision stainless steel mesh, supported by a frame, acts as a three-dimensional flame trap, extinguishing the flame and preventing its propagation, thereby avoiding secondary or multiple explosions. The flame extinguishing module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open vent panel.At the same time, pressure waves or noise generated by production equipment are significantly reduced. As flames pass through the mesh flame arrestor element, heat exchange occurs between the element and the flame, rapidly cooling the high-temperature flame, venting pressure and smoke, while further reducing pressure waves or noise generated by the equipment.Application Areas:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, machining, and solid waste treatment. Applicable equipment includes cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller grinding machines, and buildings.With increasingly stringent environmental inspections, safety has drawn more attention. In the past, explosion vent panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, such installations on indoor equipment are not permitted by safety regulations because they endanger surrounding personnel and equipment. The pressure waves and flames from an explosion may cause secondary or multiple explosions, creating risks. Therefore, relying solely on explosion vent panels for dust collectors is not reliable. We recommend using flameless venting + isolation technology (a more economical solution) or suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Blocks the explosion using an isolation valve to prevent flame propagation.Suppression: Detects sparks with a detection device, which then triggers a fire extinguishing system to instantly suppress the flame and prevent an explosion. more>

The company holds a patent for leak-proof powder, please feel free to purchase.II: 1L Internal Mixer | Experimental Internal Mixer | Small Internal Mixer Application Range: 1L Internal Mixer | Experimental Internal Mixer | Small Internal Mixer is widely used in EVA, PVC, TPR, PE, PP, PC metal powder, ceramic powder, functional masterbatch, rubber additives, shoe materials, rubber tires, sealing parts, electronic products, wires and cables, automotive products, and other raw materials for rubber and plastic products.III: 1L Internal Mixer | Experimental Internal Mixer | Small Internal Mixer Technical Features:1L Internal Mixer | Experimental Internal Mixer | Small Internal Mixer has a small footprint, energy-saving, safe, easy to operate, good dispersion, low noise, long service life, very low maintenance frequency, built-in dust collector, all technologies from Taiwan, core components imported. The 1L internal mixer is one of the small internal mixers, high precision, allowing material formulators to grasp the changes and characteristics of materials. The small internal mixer is selected by many domestic universities and has established long-term cooperation with more than 30 universities nationwide. For example: Tsinghua University, Chinese Academy of Sciences, South China University of Technology, Nanjing University, Xi'an University, Xi'an Jiaotong University, Harbin University of Science and Technology, Shanghai University, Central South University, Xiamen University, Yueyang Baling Petrochemical, Beijing Yanshan Petrochemical, Zibo Qixiang Tengda Chemical, Tianjin Petrochemical, Wuhan Wangrui Laboratory, Kraton Polymers, and many other well-known institutions.IV: 1L Internal Mixer | Experimental Internal Mixer | Small Internal Mixer Working Principle: When the 1L Internal Mixer | Internal Mixer 1L | Small Internal Mixer is working, the two rotors rotate relative to each other, clamping the material from the feed port and bringing it into the roll gap where it is squeezed and sheared by the rotors. After passing through the roll gap, it hits the lower drop door's sharp edge and is divided into two parts, which return to the top of the roll gap along the gap between the front and rear chamber walls and the rotors. During one cycle around the rotor, the material is subjected to shearing and friction everywhere, causing the temperature of the compound to rise sharply and the viscosity to decrease, increasing the wetting of the rubber on the surface of the compounding agents, allowing full contact between the rubber and the surface of the compounding agents. The compounding agent agglomerates pass through the gaps between the rotors, the rotor and the upper and lower drop doors, and the inner wall of the mixing chamber with the compound, are sheared and broken, surrounded by stretched and deformed rubber, and stabilized in the broken state. At the same time, the ribs on the rotor cause the compound to move axially along the rotor, playing a stirring and mixing role, making the compounding agents evenly mixed in the compound. The compounding agents are repeatedly sheared and broken, the compound repeatedly deforms and recovers, and the continuous stirring of the rotor ribs disperses the compounding agents evenly in the compound and achieves a certain degree of dispersion. Since the shearing action on the compound during mixing in the internal mixer is much greater than that in the open mill, and the mixing temperature is higher, the efficiency of the internal mixer is much higher than that of the open mill.V: 1L Internal Mixer | Experimental Internal Mixer | Small Internal Mixer Technical Parameters: Mixing capacity:------------------------2L Drive motor:-----------------------3.7KW Tilting motor:------------------------400W Tilting angle:------------------------110 degrees Approximate output:-------------------------1.5-2.8KG/batch Machine weight:--------------------------800KG Dimensions:---------------------------1660*900**2000mm Friendly reminder: This machine can be equipped with PLC program control according to customer requirements. more>
