[0022] As Figure 1 - Figure 2 shown, a sewage filter with convenient maintenance includes a filter tube 1 and a fixed flange 2 fixedly connected to the rear end of the filter tube 1. A filter cartridge 3 is arranged inside the filter tube 1, and the rear end of the filter cartridge 3 is designed as a flange. A liquid inlet pipe 4 is fixedly connected to the upper surface of the filter tube 1, and a liquid outlet pipe 5 is fixedly connected to the front end of the filter tube 1. An auxiliary mechanism 6 is arranged below the filter tube 1. The auxiliary mechanism 6 includes a slide rail 61 arranged below the filter tube 1. A connecting rod 62 is fixedly connected to the upper surface of the slide rail 61, and the connecting rod 62 is fixedly connected to the lower surface of the filter tube 1. A sliding rod 63 is fixedly connected to the lower side of the rear surface of the filter cartridge 3. The connecting rod 62 is fixedly connected to the slide rail 61 by screws. A limiting strip is fixedly connected to the upper surface of the slide rail 61 for limiting the sliding of the connecting rod 62 and the sliding rod 63.

[0023] By adopting the above technical solutions, when maintaining this device, the fixing bolts between the filter cartridge 3 and the fixed flange 2 can be removed, and the filter cartridge 3 can be slid out from the filter tube 1. During the sliding out process, the sliding rod 63 can slide on the slide rail 61 to assist in supporting the filter cartridge 3. This design can keep the filter cartridge 3 in a suspended state, facilitating the operator to free both hands to assist in cleaning the filter cartridge 3.

[0024] As Figure 1 、 Figure 3 and Figure 4 shown, a locking screw 7 is threadedly connected to the outer surface of the sliding rod 63 extending to the outer surface of the slide rail 61. A jack 8 is opened on the rear side of the outer surface of the slide rail 61. A positioning block 81 is fixedly connected to the upper surface of the rear end of the slide rail 61. The size of the jack 8 is such that the locking screw 7 can be inserted.

[0025] Furthermore, a reinforcing gusset plate 9 is provided above the filter pipe 1. An extension plate 10 is arranged inside the reinforcing gusset plate 9. The inner surface of the extension plate 10 extends to the lower surface and is fixedly connected with a fixing ring 11. The fixing ring 11 is sleeved on the outer circular surface of the filter pipe 1. The reinforcing gusset plate 9 is fixedly connected to the wall through a preset hole and a bolt. The filter pipe 1 can be fixed in the fixing ring 11 by using a nut on the fixing ring 11.

[0026] Furthermore, a strip-shaped groove 12 is formed through the outer surface of the reinforcing gusset plate 9, and a reinforcing screw rod 13 is arranged inside the strip-shaped groove 12.

[0027] Furthermore, both ends of the reinforcing screw rod 13 are fixedly connected with a pull rod 14, and a plug rod 15 is fixedly connected between one ends of the pull rods 14. A nut is arranged on the outer circular surface of one end of the plug rod 15 for fixing.

[0028] Working principle: When using this sewage filter with convenient maintenance, first, when maintaining this device, the fixing bolts between the detachable filter cartridge 3 and the fixing flange 2 can be removed, and the filter cartridge 3 can be slid out from the filter pipe 1. During the sliding-out process, the sliding rod 63 can slide on the slide rail 61 to assist in supporting the filter cartridge 3. After the filter cartridge 3 is slid out, the sliding rod 63 can slide to the positioning block 81 at one end of the slide rail 61. After touching the positioning block 81, the reinforcing screw rod 13 is screwed into the inside of the jack 8, and then the slid-out filter cartridge 3 can be positioned. The extension plate 10 can be inside the reinforcing gusset plate 9. After adjusting the appropriate extension length, the two are fixed by bolts. Then, the reinforcing screw rod 13 is inserted into the strip-shaped groove 12, and the stability is improved by using the pull rod 14 and the plug rod 15. This is the working principle of this sewage filter with convenient maintenance.
