Operational principle During the feeding process, the material is added to the sending tank through a double butterfly valve or an expansion butterfly valve, and the replaced air is released through the exhaust valve, making feeding easier and eliminating the reverse pressure that hinders material flow. When the sending tank is filled (displayed by the level gauge, reaching 90% of the tank volume), the feed valve and exhaust valve are both closed and sealed, and then compressed air is added to the top of the sending tank through the intake valve, The added compressed air is mixed with the material, and when the pressure in the tank reaches the set value, the bottom discharge valve will automatically open. At this time, pressure will be applied to the entire conveying pipeline, and the material will be transported in a plunger shape until it is emptied. When the pressure inside the sending tank drops to zero, the pneumatic supply is turned off, and a small amount of remaining gas is also discharged from the sending tank and conveying pipeline.
Product Features 1. High conveying pressure, up to 0.5Mpa, achieving long-distance (100-300 meters) powder conveying. 2. Low flow rate, high solid to gas ratio, and low gas consumption. 3. The material has high adaptability, strong universality, and has little impact on the quality of the material during the process, which can meet the transportation of fragile and highly abrasive materials. 4. It can achieve feeding from one point to multiple points. 5. High ash to air ratio (mixing ratio) for conveying: The length of the ash conveying pipe can reach 1:40-50 or more within 200 meters, and the air consumption is only one-third to half of that of the positive pressure dilute phase system or negative pressure system. 6. Low working pressure (usually between 0.1 and 0.2Mpa) and low flow rate: While improving conveying efficiency, it effectively reduces pipeline wear and reduces compressed air consumption. 7. High degree of automation: The system has a high degree of automation, microcomputer control, simple operation, dynamic display of operating conditions, fault alarm, sensitive response, complete processing functions, remote and manual functions, flexible, convenient, and reliable operation management. 8. Reliable system operation: The bin pump has a small volume, light weight, and is easy to install and maintain. It can be directly hung under the dust hopper of the dust collector, and supports can also be set up. This system is flexible and convenient in configuration, with main operating components and pipeline matching. Valves, instruments, and instruments all use standard components, with strong interchangeability and convenient operation and maintenance.
