[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] A stacked filter, such as Figure 1 and Figure 2 As shown, the filter includes a support 23 fixed to the ground, which forms a rectangular frame structure to support the filter tank 10. The tank 10 is rotatably connected to the support 23. The tank 10 is cylindrical in shape, and a rotating shaft 20 is integrally formed on its outer side. The rotating shaft 20 is mounted on the top of the support 23 and rotatably connected to the support 23, so the entire filter can rotate on the support 23.

[0035] A hydraulic cylinder 21 is hinged to the bracket 23. A connecting rod 22 connects the hydraulic cylinder 21 to the rotating shaft 20. One end of the connecting rod 22 is fixed to the rotating shaft 20, and the other end is hinged to the output shaft of the hydraulic cylinder 21. When the output shaft of the hydraulic cylinder 21 extends, the hydraulic cylinder 21 rotates, which drives the connecting rod 22 to move, thereby driving the rotating shaft 20 to rotate the tank 10. In this embodiment, the rotation angle of the tank 10 is between 0° and 45°. In addition, during the cleaning process of the tank 10, the hydraulic cylinder 21 can also cause the tank 10 to vibrate, thereby improving the cleaning effect.

[0036] The tank body 10 has a feed inlet 17 connected to its side. The feed inlet 17 is located at the position of the rotating shaft 20 and is connected to an external feeding device. The tank body 10 has a discharge outlet 18 connected to its bottom. After the material is filtered, it is discharged from the discharge outlet 18 at the bottom. When the hydraulic cylinder 21 drives the tank body 10 to rotate, it can facilitate the discharge of material from the discharge outlet 18, reducing the residue of material in the tank body 10.

[0037] A filter chamber is formed inside the tank body 10, and the top of the tank body 10 is sealed by a top cover 19. The top cover 19 and the tank body 10 are connected and fixed by a flange.

[0038] like Figure 3 As shown, a filter assembly is installed inside the filter chamber, and the overall size of the filter assembly matches the size of the filter chamber. The filter assembly consists of three parts: a pressure ring 1 at the top, several identical and equidistant filter discs 2 in the middle, and a circular base 3 at the bottom. Both the base 3 and the pressure ring 1 are disc-shaped. An internal screw 4 is provided on the central axis of the pressure ring 1. The internal screw 4 passes through the pressure ring 1 and several filter discs 2 in sequence, and is threaded onto the base 3, fixing the three parts into a complete filter assembly.

[0039] When the internal screw 4 is connected, hexagonal bolts 5, washers 6, and O-rings 8 are also provided for auxiliary fixing. In addition, a pressure cap 7 is provided between the O-ring 8 and the pressure cap 7 to tighten the entire pressure ring 1. A gasket 16 is also provided between the bottom surface of the filter screen assembly and the bottom surface of the filter chamber to protect the filter screen assembly and improve the installation firmness.

[0040] The outer edge of the filter assembly is provided with external bolts for auxiliary fixing of the base plate 3, filter plate 2, and pressure ring 1. The external bolts are fixed in the same way as the internal bolts, using hexagonal bolts 5, washers 6, and O-rings 8 for auxiliary fixing. To ensure the firmness of the fixing and the accuracy of the positioning, ear plates 13 and bottom pins 14 are fixed on the edge of the base plate 3, and a connecting plate 12 is provided on the edge of the pressure ring 1. The cooperation of these three components facilitates the positioning and installation of the external bolts.

[0041] The top of the pressure ring 1 has several pressure ring handles 11 integrally formed for lifting the filter assembly. During installation and disassembly, the filter assembly can be lifted and disassembled as a whole through the pressure ring handles 11. In addition, guide rods 15 for auxiliary positioning and installation of the filter assembly are fixed at the side edges of the chassis 3 and the pressure ring 1. During installation, the guide rods 15 can help position the filter assembly, thus facilitating installation.

[0042] During installation, the integrated filter assembly is positioned and placed in the filter tray by the guide rod 15. After it is placed to the bottom, the bottom connecting plate 12 presses down on the bottom pin 14 to fix it. Then, the pressure cover 7 is put on and the nut is tightened. It can then be used for normal filtration, saving replacement time. When disassembling, the filter screens are taken out one by one, cleaned, and stacked back into the filter tray 2 for future use.
