Introduction to typical uses of Roots fans (III)
- Coal jigging
Utilizing the compressed air discharged from the blower to cause water pulsation, the coal layer in the sieve plate with the water flow is constantly moving forward, and in the water to do periodic upward and downward movement. At this time, the small density coal particles float on the top, and the coal is automatically stratified on the screen plate according to the density size. Through the appropriate discharge mechanism, the middle coal and fine coal can be sorted out from the raw coal.
- The compressed air provided by the blower is used to make the small particle size heavy media form a fluidized bed with stable density. After the raw coal is added, the fine coal which is smaller than the density of the bed floats on the surface of the bed, and the heavy product sinks at the bottom of the bed. The stratified material is transported in the reverse direction by the scraper, and the refined coal is discharged from the right discharge port, while the tailings are discharged from the left discharge port.
- By utilizing the pressure and vacuum created by the blower, items in a cartridge system can be conveyed quickly. Such as postal and telecommunication departments to deliver mail, metallurgical and chemical industry departments to deliver reagents, samples and laboratory reports, radio and television departments to deliver reports, photographs and tapes, and hospitals to deliver prescription pads and medicines in the dispensary.
- The blower sends air into tower A. The wind sub-sieve in the tower adsorbs nitrogen, carbon dioxide and moisture in the air, etc., and oxygen is obtained at the top of the tower. After the adsorbent is saturated, switch the air into tower B, and oxygen can be obtained continuously. At the same time, the vacuum pump is utilized to pump the air, so that the pressure of tower A drops and the nitrogen is desorbed from the molecular sieve.
