Negative pressure pneumatic conveying
? ? Inpneumatic conveyingNegative pressure pneumatic conveying is also very important, especially powder conveying, which can greatly avoid dust pollution and the occurrence of flammable powder explosions. It can not only achieve point-to-point transportation of materials, but also multi-point transportation for automatic batching, and can be controlled by a PLC control cabinet for automatic batching.
? ? The suction system has the best ring protection performance in several conveying modes, and uses a Roots vacuum pump as the power source. The material collection components are mostly suction nozzles (movable), rotary lock air feeding valves, etc. After the Roots vacuum pump at the end of the system runs, the entire system forms negative pressure, and air is sucked into the conveying pipe due to the pressure difference between the inside and outside of the pipeline. At the same time, the material is mixed and accelerated with air before being transported to the dust removal separator. After the separation of the material and gas, the material enters the end receiving equipment through the rotary lock gas discharge valve at the bottom of the dust removal separator. The fine dust that has not been separated enters the dust collector with the airflow for purification, and the purified air is discharged into the atmosphere through a muffler.
? ? This conveying method is capable of continuous conveying, with a large conveying capacity and flexible pipeline layout. It is suitable for situations where material collection does not produce dust. The gas source at the end of the system is more environmentally friendly, and the conveyed material will not leak or escape. It is easier to transport materials with high moisture content than pressure feeding. If you needPneumatic conveying equipment Welcome to consult!
