The present invention has following characteristics:
(1) feed pipe, scraper, feed opening, collection bucket, discharge valve and discharge duct serve as a contrast high-purity plastics, and other parts adopt stainless steel (as 316,904L etc.), to reach anticorrosion, clean effect.
(2) have visor, be convenient to observe at any time charging and filtration situation.
(3) rotary drum is installed filter cloth, and material is uniformly distributed on filter cloth by cloth tray, can ensure the intact of solid crystalline.
(4) equipment is simple, and operating process is easy to control, and output is high, and energy consumption is low, can realize automation control.
(5) whole separation process is all carried out under sealing condition, does not contact cleanliness without any pollution with external environment.
(6) product purity obtaining is high, has very high economic benefit and social benefit.
