[0030] The filter 2 includes a filter chamber 21, a water inlet 22, a sludge discharge outlet 23, and a drain outlet 24.

[0031] A water inlet 22 is located in the center of the right side of the filter chamber 21, a sludge discharge outlet 23 is located at the lower end of the left side, and a drain outlet 24 is located at the upper end of the left side.

[0032] The washing pool outlet 12 and the water inlet 22 are connected by a pipe, and a water pump is installed on the pipe; a valve is installed in the water inlet.

[0033] The outside of the slag discharge port 23 is connected to the slag discharge pipe, and the drain outlet 24 is connected to the inlet of the washing pool through a pipe.

[0034] like Figure 2 As shown, the filter plate 3 includes a filter frame 31, a filter screen 32, a retaining edge 33, and a limiting pivot 34.

[0035] Two filter frame 31 up and down the edge of the filter screen 32 clamping fixed, forming a plate body. Filter screen area is greater than the filter frame formed bag type structure, can increase the filter area, but also can further enhance the efficiency of deslagging.

[0036] The edge 33 is an arc-shaped hard plate, which has the same width as the plate body. The right side of the plate body is fixed with a downward edge, and the left side of the plate body is fixed with an upward edge. When the edge is blocked at the deslagging port and the drainage port, the opening can be completely blocked, and the corresponding opening can be closed.

[0037] The plate body is arranged in the filter chamber 21. The center position of the plate body is fixed with a limiting rotating shaft 34, which is rotatably connected with the filter chamber, and one side of the limiting rotating shaft extends outward through the side of the filter chamber.

[0038] The traction mechanism 4 includes a tractor 41, an iron core 42, a swing arm 43 and a spring 44.

[0039] The tractor 41 is an electromagnetic tractor, which is arranged above the filter 2. The inside of the tractor is a plurality of annular magnetic coils. An iron core 42 is inserted into the tractor, and the iron core can slide freely. The tractor is controlled by an electric control switch, and the relative position of the iron core and the tractor can be flexibly adjusted.

[0040] The swing arm 43 is a hard long rod, the lower end of which is fixedly connected with the part of the limiting rotating shaft 34 extending out of the filter chamber; the swing arm is perpendicular to the plate body of the filter screen plate and extends upward. One side of the swing arm is connected with the iron core through a rope.

[0041] The spring 44 is arranged on the side of the swing arm away from the tractor 41, one end of the spring is fixed with the outside, and the other end is connected with the swing arm.

[0042] The tractor of the embodiment adopts an electromagnetic tractor. In actual application, the tractor can be replaced by a motor, a manual or a pneumatic traction mode, which can realize the function.

[0043] The filter has two states of filtering and deslagging in the use process.

[0044] The use process of the filter in the filtering state is as follows:

[0045] 1. The tractor is closed, the spring is in a natural contraction state, the swing arm is inclined to the left side, the filter screen plate is driven to be left low and right high, the left side edge closes the deslagging port, and the water inlet and the drainage port are opened.

[0046] 2. Open the inlet and outlet of the washing pool, and open the water pump.

[0047] 3. The sewage in the washing pool enters the filter through the pipeline, the sewage is filtered and purified through the filter screen plate, and the clean water flows back into the washing pool from the drainage port; the filter residue is blocked by the filter screen plate and located at the bottom end of the filter screen plate.

[0048] As Figure 3 shown, the use of the filter in the state of slag discharge is as follows:

[0049] 1. The puller is opened, the iron core drives the swing arm to deviate to the right side, drives the filter screen plate to be left high and right low, the left side blocking edge closes the water outlet, the water inlet and the slag discharge opening are opened; the spring is in the stretched state.

[0050] 2. The outlet of the washing pool and the slag discharge pipeline of the filter are opened, and the water pump is opened.

[0051] 3. The clean water in the washing pool enters the filter along the pipeline, flushes the filter screen plate from top to bottom, and the filter residue on the filter screen plate is flushed away by the high-pressure water flow, and the filter residue and the water flow are discharged through the slag discharge pipeline.

[0052] When filtering, the water flows from bottom to top; when discharging slag, the water flows from top to bottom. The bag type filter screen of the embodiment changes with the flow direction of the water, and rises and falls up and down, and the filter residue originally adhered to the filter screen moves and generates friction. Under the double action of water pressure and friction, the slag removal efficiency is improved.

[0053] The embodiment is used for filtering and discharging slag of liquid. In other application cases, the filter can also be used for filtering and discharging slag of gas.

[0054] The advantages of using the filter are:

[0055] 1. The filter can integrally have the filtering and slag removal effects, does not need a person to clean the filter, greatly reduces the labor cost, and is convenient for daily maintenance and use.

[0056] 2. The filtering and slag removal states are replaced only by controlling the swing arm displacement, the structure is simple, the strength is high, and damage is not easy to occur, so that subsequent frequent maintenance is avoided.

[0057] 3. The filter screen is extruded on the reverse side of the adhered residue, the slag removal efficiency is higher, and the risk of filter screen blockage is completely avoided.

[0058] 4. The filter screen can be designed as a bag type, the screen area is increased, and the slag removal efficiency is further improved.

[0059] The above is only the preferred specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
