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 the material through pipes (or nozzles) inhalation, through conveying pipe up to the cyclone (or Volume) unloader unloading pneumatic conveying equipment type, after the dust laden air is discharged through the dust purification. Vacuum pumping system is mainly used in the foundry industry sand suction plenum conveying device parameters, out of the box off the sand after the hot sand sucked through the conveying pipe to discharge hopper, in pneumatic conveying can play old sand regeneration, cooling, grading , dust effect. Vacuum blower itself has some problems pneumatic conveying equipment standards, such as pipes wear, productivity is not high, a large fan noise, etc., who generally promote the use in the foundry industry, but there are still a lot of factories adhere to use, because it can play in addition to enhance the role of transport, but also has good old sand regeneration, good cooling effect and to ash effect pneumatic conveying equipment, also reduce the amount of binder and water is added to improve the quality of the casting. Types of pneumatic conveying material modeling modeling material features many of the foundry industry, almost all raw materials can be used pneumatic conveying, including powdered materials (clay powder, coal, coke powder, red mud, etc.); granular material (quartz sand, reclaimed sand casting, iron balls, steel shot, etc.) viscous material (sand, sand, etc.). Achieve a variety of process requirements in pneumatic conveying process can achieve a variety of process requirements, thereby improving the quality of sand casting, such as pneumatic conveying achievable mix of materials, cooling, drying, grading, dust and so on, to foundry sand regeneration, shot, iron shot and cast steel shot after shot blasting crushing rate is high, the use of pneumatic conveying up to grade, dust a variety of effects.
