Several typical pneumatic conveying system in the form of vacuum suction vacuum blower is a centrifugal fan or high-pressure water ring vacuum pump for the gas source for pneumatic conveying equipment, materials through pipes (or nozzles) inhalation, through conveying pipe up to Tornado (or volume) unloader unloading, after purification dust discharged through the dusty air. Vacuum pumping system is mainly used in the foundry industry sucking sand out of the box off the sand after the hot sand sucked through the conveying pipe to discharge grudge conveying equipment standards in the pneumatic conveying system can play old sand regeneration, cooling, grading , dust effect. Vacuum blower itself has some problems, such as pipe wear, productivity is not high, a large fan noise, etc., in the foundry industry has generally promote the use, but there are still a lot of factories adhere to use, because it can play in addition to enhance the role of transport outside types of pneumatic conveying equipment, but also has good old sand regeneration, good cooling effect and go gray effect, also reduce the amount of binder and water is added to improve the quality of the casting. High density pneumatic conveying system features one or trivial migrate settings change parts less gas in the brief crushing conveying equipment supplier, and one inlet valve, outlet valve of moving parts, no other 捐募 equipment; Instrument air supply and transport gas source public; hopper without setting set gasification furnishings, gasification heater fan and the atmosphere; Run maneuvering changeable, continuous operation can also be run as scheduled. Second, piecemeal trivial walks gray gas ratio high-density high-pressure plug-flow delivery, broken notes less shortened air transport more materials capable of transporting cement ratio of up to 80-100. Lying to 100m from the carrying away of pulverized coal, for example, transport gray-gas ratio of up to 80kg / kg.
