Solid-liquid separation precision filter

Abstract

The invention provides a solid-liquid separation precision filter. A circle of stainless steel filter screen is arranged in a filter cavity, the mesh size of the steel screen is fixed, deformation isnot likely to happen, and filtering is precise; the filter screen is internally stirred by a stirring device, vortexes are generated during stirring to promote the solution to scour the filter screen,separation of the solution is promoted, solid substances in meshes can be flushed off, and blockage is prevented; the filtering cavity is sealed by an upper cover and a lower cover, a pressurizing port is formed in the upper cover, and high-pressure gas is added into the pressurizing port to promote the filtering efficiency; the stirring device are spiral blades from top to bottom, filtrate is pushed downwards while stirring is conducted, the filtrate is pressed downwards in the funnel-shaped filtering cavity, and filtering is also promoted.

Description

technical field [0001] The invention relates to a filter, in particular to a high-efficiency precision filter for solution solid-liquid separation. Background technique [0002] Existing filters, especially those that realize solid-liquid separation, usually use gauze filtration, carbon adsorption, etc. The disadvantage of using these methods at that time is that solid substances are easily blocked in the filter holes, resulting in a gradual decrease in filtration efficiency. And cause the pressure of the feed port to increase. In addition, only preliminary filtration can be achieved, and solid particles still exist in the filtrate. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide an efficient and precise filter. [0004] In order to achieve the above purpose, the technical scheme adopted in the present invention is: [0005] A solid-liquid separation precision filter includes a filter cavity, an upper cover and a lower cover, the uppe...

And cause the pressure at the inlet to increase

In addition, only preliminary filtration can be achieved, and there are still solid particles in the filtrate
