Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

Example 1

The filter provided by the embodiment comprises a filter cylinder body 1, a filter screen 6, a framework 10 for supporting the filter screen 6, a fluid inlet 2 and a fluid outlet 4 which are arranged on the filter cylinder body 1, wherein the filter screen 6 is of a cylindrical structure.

Fluid inlet 2 is in the outside of filter screen 6, fluid outlet 4 is in the inboard of filter screen 6, the filter still includes sparge water interface 3, drain 8, sparge water interface 3 is in the inboard of filter screen 6, drain 8 is in the outside of filter screen 6, drain 8 and liquid import all are in the lower part of filter barrel 1, fluid outlet 4 and sparge water interface 3 all are in the upper portion of filter barrel 1, fluid inlet 2, fluid outlet 4, sparge water interface 3, drain 8 all sets up the valve.

The use process of the filter is as follows: fluid flows through the fluid inlet 2 to the screen 6 and is filtered through the screen 6 out the fluid outlet 4 and out of the filter into the next machine.
