[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown, a sewage filtering device for papermaking production includes an outer cylinder 1, a top cover 3 is provided on the top of the outer cylinder 1, an inlet pipe 4 is provided on the upper side, and an outlet pipe 5 and a sewage pipe 6 are provided on the bottom. The inlet pipe 4 is tangent to the outer cylinder 1, one end of the outlet pipe 5 is connected to the filter cylinder 2, and the other end passes through the bottom surface of the outer cylinder 1 and extends to the outside of the outer cylinder 1. Valves are installed on the outlet pipe 5 and the sewage pipe 6.

[0019] like Figure 3 As shown, a filter cartridge 2 is installed inside the outer cartridge 1 , a plurality of filter holes are arranged on the side of the filter cartridge 2 , and the filter cartridge 2 is installed on the inner bottom surface of the outer cartridge 1 through a fixing seat 16 .

[0020] Connect the water inlet pipe 4 to the water pump, and the sewage is transported to the inner part of the outer cylinder 1 through the external water pump. After the impurities are filtered out by the filter cylinder 2, it is discharged through the water outlet pipe 5. The impurities are retained between the outer cylinder 1 and the filter cylinder 2. During maintenance, the valve on the sewage pipe 6 is opened to discharge the impurities.

[0021] like Figures 2 to 4 As shown, two annular rails 7 are installed on the inner wall of the outer cylinder 1, and a mounting frame 8 is provided on the inner side of the annular rail 7 and is sleeved on the outer side of the filter cylinder 2. The mounting frame 8 includes two annular plates 8.1, and a plurality of vertical plates 8.2 are fixedly connected between the two annular plates 8.1. A plurality of sliders 9 slidably connected to the annular rails 7 are fixedly connected at both ends of the mounting frame 8, and a plurality of brushes 10 are installed on the inner side of the mounting frame 8 through a fixed block, and an ear plate 11 is fixedly connected on the outer side. The ear plate 11 is installed on the vertical plate 8.2, and its installation height is adapted to the height of the water inlet pipe 4. An inner gear ring 12 is installed on the top of the mounting frame 8, a rotating shaft 13 is installed through the top cover 3, a hand wheel 14 is fixedly connected to the top of the rotating shaft 13, and a gear 15 is installed at the bottom, a positioning seat 17 is fixedly connected to the top of the top cover 3, the rotating shaft 13 penetrates the positioning seat 17, and the rotating shaft 13 is rotatably connected to the positioning seat 17 through a bearing.

[0022] Since the water inlet pipe 4 is tangent to the outer cylinder 1, and the height of the ear plate 11 is matched with the height of the water inlet pipe 4, the sewage will generate an impact force on the ear plate 11 when entering the outer cylinder 1, prompting the ear plate 11 to drive the mounting frame 8 to rotate along the annular rail 7, and the mounting frame 8 drives the brush 10 to rotate, thereby continuously cleaning the outside of the filter cylinder 2 and preventing the filter holes from being blocked.

[0023] When the flow rate of sewage entering the outer tube 1 is low, the impact force on the ear plate 11 is small. At this time, the rotating shaft 13 can be rotated by the hand wheel 14, and the rotating shaft 13 drives the inner gear ring 12 and the mounting frame 8 to rotate through the gear 15 to achieve cleaning of the outside of the filter tube 2.

[0024] In actual use, after the sewage enters the outer tube 1, it impacts the ear plate 11, so that the ear plate 11 drives the mounting frame 8 and the brush 10 to rotate, thereby realizing automatic and continuous cleaning of the outside of the filter tube 2 to prevent the filter holes from being blocked. It is only necessary to discharge the impurities through the sewage pipe when the machine is shut down for maintenance, thereby effectively reducing the number of manual maintenance and cleaning of the sewage treatment device.
