Summary of the invention
The utility model is for avoiding the existing deficiency of above-mentioned technology, a kind of pure liquid waste solution equipment for separating liquid from solid is provided, in the hope of improving the filter effect of equipment, reduce material loss, reducing labour intensity.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model alcohol liquid waste solution equipment for separating liquid from solid is described separator to be set be by the stage casing circle tube tank body, be arranged on the top cover at tank body top, the closed container that the filter cake bottom consists of that unloads that is undertaken on the Rotary-table of tank body lower part and is arranged on described Rotary-table bottom; Be each collector tube that vertically be arranged in parallel at described tank body internal upper part; The lower end of described each collector tube is set to the filter core mouth of pipe with interior tooth, and filter core is connected on the filter core mouth of pipe, and described filter core is the polymeric membrane filter core; The top of each collector tube leads to the outside of tank body by drain pipe, and is connected with outside discharge nozzle, and the charging aperture that is connected with feed pipe by inlet valve is arranged on the sidepiece of Rotary-table.
The design feature of the utility model alcohol liquid waste solution equipment for separating liquid from solid also is:
The purge gas introducing port is set respectively at described top cover with on described discharge nozzle.
At the described filter cake bottom that unloads refluxing opening is set, described refluxing opening is communicated with feed pipe by return duct and return valve.
At the described pneumatic bottom opener of filter cake bottom setting take compressed air as power that unload.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is to carry out Separation of Solid and Liquid at airtight separation tank body, and seal point is few, and good sealing effect has solved material from leakage, thereby has reduced supplies consumption, has alleviated the pressure of safety and environmental protection.
2, adopting filter core in the utility model is the polymeric membrane filter core, and the penetrating aperture of filter core can be set arbitrarily according to the size of solid particle, has improved solid-liquid separation effect.
3, unload the filter cake bottom in the utility model and can utilize compressed air, pneumatic bottom opener is set, the discharge process that unloads the filtrate bottom is simplified greatly, reduce working strength.
