the first chamber 001 is the area between the inner wall of the first tank 100 and the outer wall of the screen assembly 200; second chamber 002 is an area inside screen assembly 200;
the screen assembly 200 includes an outer screen 210 and an inner screen 220, the outer screen 210 is sleeved outside the inner screen 220 and forms a downward inclined surface inclined from top to bottom, and the outer screen 210 and the inner screen 220 can be shifted to switch between an open state and a closed state;
when the screen assembly 200 is in the open state, the filtering holes of the outer screen 210 are partially overlapped with the filtering holes of the inner screen 220, and at this time, the first chamber 001 is communicated with the second chamber 002;
when the screen assembly 200 is in the closed state, the filtering holes of the outer screen 210 are misaligned with the filtering holes of the inner screen 220, and the first chamber 001 is isolated from the second chamber 002.
Because the downward inclined plane of a top-down slope that outer filter screen 210 and inlayer filter screen 220 formed, consequently the filter residue is inevitable to drop down along the inclined plane, and although the filter residue of first cavity 001 bottom can be more and more along with the lapse of time, the filter part of filter screen subassembly 200 top can be guaranteed to have no filter residue to pile up in longer time, can normally high-efficiently use, can not blockked up by the filter residue. Thus, a high filtering effect of this inclined filtering surface lasts much longer than with the existing transverse plane surfaces.
In addition, in the washing process of the inclined plane, filter residues can flow downwards along the inclined surface, splashing occurs less, under the condition of controlling the flow and the flow speed of washing water, fluid can flow downwards along the outer surface of the filter screen assembly 200, and the problem that the filter residues are splashed due to the fact that the washing water is carried from top to bottom because the filter screen is in a plane type and can not only pollute the inner wall of the separation tank but also return to the filter screen again in the prior art can be avoided.
With regard to the structure of the first tank 100, specifically:
a cavity is arranged in the first tank 100, the filter screen assembly 200 divides the cavity into a first cavity 001 and a second cavity 002, the bottom of the first cavity 001 is provided with a first slag outlet 110, and the top of the first cavity 001 is provided with a feed inlet 120 and a gas-liquid inlet 130; the second chamber 002 is provided at the bottom with a second slag outlet 140 and a gas-liquid outlet 150.
The filtration process is briefly described as follows:

The filtrate enters the second chamber 002 after passing through the screen assembly 200, then flows down along the inner wall surface of the screen assembly 200, and finally is discharged to the filtered liquid outlet from the gas-liquid outlet 150 at the bottom of the second chamber 002.
Regarding the structure of the screen assembly 200, in detail:
the outer layer filter screen 210 and the inner layer filter screen 220 are both in a circular truncated cone structure, and the bottoms of the two filter screens are both provided with folded edges; the top of the outer screen 210 is connected with a gear driving mechanism 230, and the gear driving mechanism 230 is used for driving the outer screen 210 to rotate around the axis thereof; the folded edge of the inner screen 220 is coupled to the inner wall of the first tank 100.
Since the outer screen 210 and the inner screen 220 can be shifted from each other, when the openings of the two screens are partially overlapped, the passages of the outer screen 210 and the inner screen 220 are opened, and at this time, the filtrate can pass through the screen assembly 200. When the screens are completely non-overlapping, the passages of the outer screen 210 and the inner screen 220 are closed, and filtrate cannot pass through the screen assembly 200.
The slag tapping process is briefly described as follows:
in the slag discharging process, the first slag outlet 110 is opened, the outer filter screen 210 rotates to drive the filter residue accumulated at the bottom of the first cavity 001 to rotate, and the filter residue is thrown out to the first slag outlet 110 in the rotating process. Further, the bottom of the outer screen 210 is provided with an inclined guide plate which is inclined downward from a direction toward the first slag hole 110.
Brief description of forward flushing:
the device also comprises a forward flushing mechanism, wherein the forward flushing mechanism is arranged in the first cavity 001 and comprises a transverse flushing pipe 310 arranged at the top of the first tank body 100 and a longitudinal flushing pipe 320 which is respectively arranged at two ends of the transverse flushing pipe 310 and communicated with the transverse flushing pipe 310;

Because the outer layer filter screen 210 and the inner layer filter screen 220 are in a slope structure, water flows from top to bottom to form impact force, which is very beneficial to removing filter residues. Further, the outer screen 210 may be activated at this point, and the water flow may better contact and take away the gap between the outer screen 210 and the inner screen 220 during rotation of the outer screen.
The purging is briefly described as follows:
because the existing cleaning mode adopts a wet type flushing mode, the problems of residual liquid and dregs of a decoction can not be avoided. In the scheme, a purging mode is added on the basis of the traditional wet-type washing, and the scheme specifically comprises a forward purging mechanism and a reverse purging mechanism, wherein the forward purging mechanism shares the same pipeline with the part in the first tank body 100; the portions of the reverse purge mechanism within the first tank 100 share the same piping.
The same shared pipeline not only can effectively save the volume of equipment, but also can perform air removal operation on residual liquid in the pipeline after wet cleaning, take away residual liquid in the pipeline, effectively maintain the dryness in the pipeline and avoid the influence of residual liquid on the next filtering operation.
In addition, forward purge and backward purge can also effectively blow off the filter residue on filter screen surface, avoid the filter residue to remain.
Specifically, the third valve 3, the fourth valve 4 and the eighth valve 8 are opened, and when the other valves are closed, the forward purging mechanism is started; and the third valve 3, the seventh valve 7, the fifth valve 5 and the sixth valve 6 are opened, and when the other valves are closed, the reverse purging mechanism is started.
