[0007] Optionally, the support frame includes a first inner ring and a first outer ring, the first inner ring and the first outer ring are connected by a plurality of support rods, the filter frame includes a second inner ring and a second outer ring, the second inner ring and the second outer ring are connected by a plurality of support plates, the water inlet hole is arranged on the first outer ring, the water outlet hole and the mounting groove are arranged on the second inner ring, and a plurality of the first inner rings and a plurality of the second inner rings enclose the water outlet channel.

[0008] By adopting the above technical solution, the liquid discharged from the water inlet pipe enters the support frame and the filter frame from the corresponding water inlet hole, the impurities in the liquid are filtered by the filter plate, and the liquid filtered by the filter plate is discharged from the water outlet hole into the water outlet channel, and then discharged from the water outlet channel. The impurities fall on the filter plate, thereby achieving solid-liquid separation.

[0009] Optionally, each filter frame is detachably connected to at least two filter plates.

[0011] Optionally, both the first inner ring and the second inner ring are connected to a positioning ring, and both the first inner ring and the second inner ring are provided with a positioning groove for cooperating with the positioning ring.

[0012] By adopting the above technical solution, the positioning ring on the first inner ring is clamped into the positioning groove on the second inner ring, and the positioning ring on the second inner ring is clamped into the positioning groove on the first inner ring. The outer surface of the positioning ring fits with the inner wall of the positioning groove, and the inner wall of the positioning groove restricts the horizontal movement of the positioning ring, thereby improving the stability between the first inner ring and the second inner ring, that is, improving the effect of the filter plate being clamped by the first inner ring and the second inner ring.

[0017] Optionally, a cover plate is detachably connected to a side of the support frame farthest from the mounting seat and away from the mounting seat, the cover plate is provided with a plurality of through holes, and the locking block is used to abut against the cover plate.

[0018] By adopting the above technical solution, when there is too much liquid between the top cover and the support frame and the filter frame, the liquid enters the support frame and the filter frame through the water inlet hole at a slow speed, and the liquid level rises until the liquid is higher than the cover plate. The liquid then enters the support frame and the filter frame through a number of through holes, which can both improve the efficiency of liquid filtration and prevent the liquid level from rising further.

[0019] Optionally, the fixing structure includes a fixing rod rotatably connected to the first outer ring, the fixing rod is rotatably connected to the first outer ring closest to the mounting seat, the fixing rod is slidably connected to a fixing block, the fixing block is used to abut against the first outer ring farthest from the mounting seat, and the fixing rod is threadedly connected to a nut for abutting against the fixing block.

[0020] By adopting the above technical solution, after a number of support frames and a number of filter frames are sleeved on the positioning column, the fixing rod and the sliding fixing block are rotated so that the fixing block abuts against the first outer ring farthest from the mounting seat, and then the nut is rotated so that the thread abuts against the fixing block. The fixing block applies force to the first outer ring farthest from the mounting seat, so that the number of support frames and the number of filter frames are clamped by the fixing block and the mounting seat, that is, the filter plate is clamped by the corresponding support frame and the filter frame, thereby improving the stability of the placement of the filter plate.

[0021] Optionally, the mounting seat is connected to a drain pipe, the top cover covers the water inlet of the drain pipe, and the drain pipe is connected to a drain valve.

[0022] By adopting the above technical solution, when it is necessary to clean the impurities on the filter plate, the drain valve is opened and the water on the mounting seat is discharged from the drain pipe to prevent the water accumulation on the mounting seat from affecting the cleaning of the impurities on the filter plate.

[0023] Optionally, the body is connected to a baffle, and the baffle surrounds the mounting seat.

[0024] By adopting the above technical solution, even if liquid leaks from the gap between the top cover and the mounting seat, the baffle can surround and block the leaked liquid, making it easy for staff to observe the leakage.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Insert the filter plate into the installation groove. The filter plate fits with the inner wall of the installation groove. The inner wall of the installation groove limits the horizontal movement of the filter plate. The support frame is stacked on the filter frame. The fixed structure fixes several support frames and several filter frames, so that the filter plate is clamped by the corresponding support frame and filter frame, thereby limiting the vertical movement of the filter plate and improving the stability of the filter plate placement.

[0027] 2. After several support frames and several filter frames are sleeved on the positioning column, the locking block is rotated toward the mounting seat so that the several support frames and several filter frames are clamped by the locking block and the mounting seat, that is, the filter plate is clamped, thereby improving the stability of the filter plate placement.
