[0026] The specific problem addressed by this specific embodiment is that the inventor of this application discovered the following problem during the specific operation process: the most common solid-liquid separation structure of the sewage purification tank is the filter-type solid-liquid separator, which has a simple structure and high solid-liquid separation efficiency. However, during use, due to the large amount of particles and suspended matter in the sewage, the mesh of the filter is easily clogged, resulting in a decrease in the filtering effect of the filter, and the filter needs to be cleaned manually regularly. Therefore, in response to the above problem, the inventor proposes a solid-liquid separation structure for a sewage treatment purification tank.

[0027] Figure 1-Figure 5As shown, a solid-liquid separation structure of a sewage treatment purification tank specifically described in this scheme is based on the structure of an existing purification tank, and a solid-liquid separation component 1 is installed in the purification tank. Specifically, the single-layer screen filter set in the prior art is set as a double-layer screen filter plate 2, and a cleaning inner plate 3 that can be pulled left and right is set in the cavity of the screen filter plate 2. The cleaning inner plate 3 cleans the inner cavity and the top plate of the screen filter plate 2, and the blockages on the filter hole 21 and under the filter hole 21 are cleaned, and on the basis of the cone shape of the filter hole 21, the debris that is larger than the diameter of the filter hole 21 and has entered the filter hole 21 is cut off, so that the debris in the filter hole 21 can move downward, thereby removing the blockage of the filter mesh filter hole 21 by the debris, and enhancing the self-cleaning ability of the screen filter plate 2.

[0028] The solid-liquid separation component 1 includes a sieve filter plate 2, the interior of which is provided with a cavity, and a cleaning inner plate 3 is slidably installed on the sieve filter plate 2, and the inner cavity and the top plate of the sieve filter plate 2 are covered by the cleaning inner plate 3 wrapped around it. Specifically, the cleaning inner plate 3 includes a cutting plate 31 arranged in the cavity and a cleaning plate 32 placed on the sieve filter plate 2, and the cleaning plate 32 is arranged in a straight plate shape, and the cleaning plate 32 is connected to the cutting plate 31 through an end plate 33, and the end plate 33 is arranged in a T-shape and the cleaning plate 32 is connected to the upper end of the end plate 33, and the distance between the vertical structure of the end plate 33 and the side wall of the sieve filter plate 2 is not less than the distance between adjacent filter holes 21.

[0029] A plurality of material passing grooves 34 are formed on the cutting plate 31 . The opening centers of the material passing grooves 34 coincide with the centers of the plurality of filter holes 21 . Cutting grooves 35 are formed on the left and right side walls of the material passing grooves 34 .

[0030] The upper end plate 33 of the sieve filter plate 2 is provided with a filter hole 21, and the lower end plate 33 thereof is provided with a discharge trough 22 adapted to the feed trough 34. The feed trough 34 runs through the upper end surface and the lower end surface of the draw-cut plate 31, and a connecting plate 36 is installed on the front and rear side walls of the feed trough 34. The connecting plate 36 is clamped on the slide plate 23 installed in the inner cavity of the sieve filter plate 2, and the slide plate 23 is installed on the inner wall of the sieve filter plate 2. The cutting groove 35 is connected with the feed trough 34 and the cutting groove 35 is opened in a trapezoidal shape. The cutting groove 35 and the draw-cut plate 31 are provided with an acute angle to establish a cutting environment for the draw-cut plate 31 to cut the blockage of the filter hole 21. The opening position of the discharge trough 22 is adapted to the opening position of the filter hole 21, and the opening width of the discharge trough 22 is not less than the opening width of the feed trough 34. After the end plate 33 is stressed, in this embodiment, the end plate 33 can be forced to move to the left and right to return to the initial position as the ultimate goal. Therefore, based on existing means, this embodiment is specifically implemented by a cylinder, and the cylinder pushes the cutting plate 31 to move left and right, so that during the sliding process between the top plate of the cutting plate 31 and the inner wall of the screen filter plate 2, the debris suspended in the filter hole 21 is cut off and falls into the feed trough 34, and when the feed trough 34 coincides with the discharge trough 22, the debris falls out of the discharge trough 22. The cleaning plate 32 is provided with an extrusion hole 37 that coincides with the position of the filter hole 21, and the extension distance of the end plate 33 outside the cavity of the screen filter plate 2 is not less than the distance between adjacent filter holes 21. By providing a cutting groove 35 and a material passing groove 34 connected to the cutting groove 35 on the cutting plate 31, on the one hand, the debris passing through the filter hole 21 can be transferred to the next processing space more quickly, avoiding the problem of back-blocking caused by accumulation at the lower end of the filter hole 21; on the other hand, an acute angle is provided between the cutting groove 35 and the cutting plate 31 to establish a cutting environment for the cutting plate 31 to cut the blockage of the filter hole 21, cut the debris in the filter hole 21, reduce the extension length of the debris in the filter hole 21, and after the cleaning plate 32 synchronously cuts the debris at the upper end of the filter hole 21, the probability of the debris passing through the filter hole 21 is increased, further releasing the space occupied by the debris in the filter hole 21.
