A partition is welded to the inner wall of the filter main body. A plurality of wire baskets are movably inserted into the interior of the partition. The tops of the wire baskets are fixedly connected with connecting cylinders, and the connecting cylinders communicate with the wire baskets. Pull rods are welded to the inner walls of the connecting cylinders. Two symmetrically arranged rectangular positioning blocks are welded to the outer walls of the connecting cylinders. A threaded rod is threadedly connected to the top of the partition. A handle is fixedly connected to the top of the threaded rod. A fixed sleeve is fixedly sleeved around the periphery of the threaded rod. Four symmetrically arranged pressing rods are fixedly connected to the outer wall of the fixed sleeve. By mainly setting components such as pressing rods, threaded rods, L-shaped positioning plates, connecting cylinders, and pull rods, when replacing the filter bag of this practical device, only need to rotate the handle by a certain angle, then hold the pull rod and easily take out the wire basket and the filter bag, and then clean and replace them. When installation is required, under the positioning of the rectangular positioning blocks, insert the wire basket back again, and then rotate the handle in the reverse direction to the initial position to complete the replacement. The whole process is simple to operate, convenient to use, time-saving and labor-saving, and improves the practicability of the device.

[0004] The above-mentioned filter for solid-liquid separation still has certain deficiencies: Since the volume sizes of solid particles are different, once the solid particles block the mesh holes of the filter screen, it will affect the use of the filter at this time, and further reduce the working efficiency of the device. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a filter for solid-liquid separation to solve the problems existing in the prior art.

[0006] To solve the above technical problems, the present utility model provides the following technical solution: A filter for solid-liquid separation, comprising a filter body. One side of the upper surface of the filter body is communicated with a first connecting pipe. Both ends of the filter body are communicated with second connecting pipes. The surface of the second connecting pipe is fixedly sleeved with a first mounting ring. A plurality of connecting through holes are penetrated through the side wall of the first mounting ring in a circular array. Two limiting sliding grooves are symmetrically opened along the center inside the second connecting pipe. One side inside the limiting sliding groove is detachably installed with a hydraulic telescopic rod. One side inside the second connecting pipe is connected with a filter screen through the limiting sliding groove. Two connecting plates are symmetrically fixedly connected to the surface of the filter screen along the center. One side of the inner wall of the filter body is fixedly connected with an automatic blockage clearing component.

[0007] Wherein, the surface of the connecting plate is adapted to the inside of the limiting sliding groove, and one end of the hydraulic telescopic rod is connected to the side wall of the connecting plate.

[0008] Wherein, the surface of the filter screen is adapted to the inside of the second connecting pipe, and the inner diameter of the second connecting pipe is the same as the inner diameter of the filter body.

[0009] Wherein, the automatic blockage clearing component includes a second mounting ring and a hydraulic telescopic cylinder. Two hydraulic telescopic cylinders are symmetrically and detachably installed on the side wall of the second mounting ring along the center.

[0010] Wherein, the surface of the second mounting ring is connected to one side inside the filter body, and one end of the hydraulic telescopic cylinder is fixedly connected with a third mounting ring.

[0011] Wherein, a blockage clearing cone is fixedly connected inside the third mounting ring, and the surface of the third mounting ring is attached to the inner wall of the filter body.

[0012] Wherein, a plurality of flow through holes are opened on the surface of the blockage clearing cone in a circular array, and the cross-sectional area of the blockage clearing cone is smaller than the cross-sectional area of the second mounting ring.

[0013] The beneficial effects of the above technical solution of the present utility model are as follows:

[0014] 1. In the above solution, the filter is provided with a limiting sliding groove, a hydraulic telescopic rod and a connecting plate. When solid particles block the filter screen, the hydraulic telescopic rod is started at this time to drive the connecting plate to move. Because the side wall of the connecting plate is connected to the surface of the filter screen, the movement of the connecting plate can drive the blocked filter screen to move until the filter screen is moved out of the inside of the filter body, so as to facilitate the cleaning of the blocked filter screen. Because the hydraulic telescopic rod has the function of automatic expansion and contraction, the position of the filter screen can be adjusted, so as to facilitate the cleaning of the filter screen and save the working time required.

[0015] 2. In the above solution, the filter is provided with an automatic blockage clearing component. After the filter body is used, the hydraulic telescopic cylinder inside the automatic blockage clearing component is activated at this time, so that it drives the third mounting ring and the blockage clearing cone to move until the blockage clearing cone is moved out of the inside of the filter body. Because the surface of the third mounting ring fits with the inner wall of the filter body, impurities on the inner wall of the filter body can be cleaned while the third mounting ring moves, thereby facilitating the secondary use of the filter body and enhancing the practicability of the device.
