An inlet hole 11 for cleaning the inside of the tank is provided in the upper part of the side wall of the tank body. The inlet hole is used to clean the debris inside the tank body and the mud sticking to the filter screen to make the filter screen recover a better filtering effect. A tank drainage hole 14 for discharging the filtered mud is provided in the lower part of the side wall of the tank body. At least one drainage hole is provided, and multiple drainage holes can prevent single blockage. Inside the tank body, tank connecting plates 17 for connecting the water guide plate and the filter screen are provided in the upper and lower parts. The tank connecting plates are annular and fixedly sealed on the inner side wall of the tank body.

[0037] Reference Figures 5 to 8 , water guide plate 4, which is provided on the inner side wall of the tank body and surrounds the inner side wall, includes a plate surface for shaping. Longitudinal water guide grooves 421 for filtering mud and evenly distributed are provided on the plate surface. A transverse water guide groove 423 is provided below the longitudinal water guide grooves. The longitudinal water guide grooves are communicated with the transverse water guide groove, and the transverse water guide groove is communicated with the tank drainage hole and discharges the filtered water outside the tank.

[0038] Reference Figures 8 to 11 , filter screen assembly 3, is arranged inside the water guide plate and is composed of multiple layers of filter screens. The edge is connected to the edge of the water guide plate, and the filter screen is in contact connection with the part where the water guide plate bulges inward. Guide filter connecting plates 41 for sealing connection with the tank body are provided at the edges of the water guide plate and the filter screen. The guide filter connecting plates are hermetically connected to the tank connecting plates 17 through screws 5; a water guide plate drainage port 43 is provided at the lower part of the water guide plate, and the water guide plate drainage port is communicated with the tank drainage hole 14.

[0039] Reference Figure 4 and Figure 5, the stirring device 2 includes stirring blades 23, blade brackets 27, a stirring shaft 24 disposed inside the tank, and a driving motor 21 disposed at the upper end outside the tank. The stirring blades are connected to the stirring shaft through blade connection plates. There is a gap between the outer ends of the blades and the filter screen assembly. The stirring shaft is disposed on the axis of the tank. The upper end of the stirring shaft is connected to the output main shaft of the driving motor. The driving motor 21 is a high-torque reduction motor and can be speed-regulated through an electric control box. The lower end of the stirring shaft is connected to the bearing in the middle of the blade bracket. The blade bracket 27 is fixedly connected to the inner side wall of the tank. When the stirring shaft rotates, the blades drive the mud to flow up and down and rotate. The arrow directions in the figure are as follows: the vertical arrow indicates the schematic direction of the mud entering the tank and then being discharged from the tank, the horizontal arrow indicates the direction of the filtered water entering the filter net, and the arrow at the drainage hole 14 of the tank indicates the schematic direction of the discharged water.

[0040] Among them, the stirring blades 23 of the stirring device are hollow spiral blades. The hollow spiral blades, that is, the blades are spiral-shaped and hollow in the middle, making the blades in a strip spiral shape. One blade spirals 1 - 3 turns. The upper end of the hollow spiral blade is connected to the upper part of the stirring shaft through an upper blade connecting rod 22, and the lower end of the hollow spiral blade is connected to the lower part of the stirring shaft through a lower blade connecting rod 25.

This enables the blades to be not only positioned but also facilitates the installation and maintenance of the blades. The hollow spiral blades can be composed of two to six hollow spiral blades to form a blade assembly to improve the stirring efficiency. This embodiment is composed of two spiral blades, and each blade is provided with a blade fixing plate 28 in the middle. The utility model can use various stirring blades, but preferably hollow spiral blades. Since the edges of the hollow blades are close to the filter screen, this strengthens the flow rate of the mud near the filter screen.

A water guide plate drain port 43 is arranged at the edge of the transverse water guide groove, and the water guide plate drain port is communicated with the tank drain hole 14. Due to the arrangement of the connecting grooves, the water guide grooves are interconnected with each other, the water is diverted and converged and flows out from the tank drain hole, avoiding local blockage and affecting the filtration effect. Since the water guide plate is formed into one body, it is more convenient to install, the water guide grooves are interconnected with each other, and it is more convenient for water to flow smoothly. The arrow direction in the figure is the water flow direction.

[0042] The filter screen assembly 3 is composed of multiple layers of filter screens stacked together, including a supporting bottom screen and a filter screen. The supporting bottom screen is provided with 1-5 layers on the side close to the inner wall of the tank, with a mesh number of 6-12 meshes, and the filter screen is provided with 2-6 layers on the inner side, with a mesh number of 400-800 meshes.

The filter screen is used in combination with the water guide plate, and a connecting edge is provided at the edge to connect the filter screen and the edge of the water guide plate into one body. The connecting edge not only strengthens the connection strength between the water guide plate and the edge of the filter screen, but also facilitates the sealing connection between the water guide plate and the filter screen and the inner side wall of the tank. The connection with the inner side wall of the tank is preferably a threaded connection. The threaded connection is convenient for installation, maintenance, replacement and disassembly, and is convenient for maintenance, which can extend the service life of the whole equipment. The seal uses a silica gel pad.
