[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. When sewage is treated, a filter will be used to filter the sewage so that it can be discharged or recycled after treatment.

[0003] When the existing sewage filter is in use, the sewage will be filtered twice by setting a coarse filter screen and a fine filter screen inside the sewage filter. However, a cleaning brush is generally installed inside the fine filter screen, which causes the coarse filter screen to be easily clogged after long-term use, affecting the use effect of the filter. To this end, we propose a sewage filtration device to solve the above problem. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-4 A sewage filtering device includes a filter body 1, a water inlet 2 is installed above one end of the filter body 1, and a drain outlet 3 is installed below the other end of the filter body 1, a separator ring 4 is fixedly connected to the inner wall of the filter body 1, a coarse filter cartridge 5 is fixed on one side of the separator ring 4, and a fine filter cartridge 6 is fixed on the other side of the separator ring 4, a driving mechanism 7 is installed inside the filter body 1, and a cleaning mechanism 8 is fixed to the end of the driving mechanism 7, through which the filtered materials of the coarse filter cartridge 5 and the fine filter cartridge 6 can be easily cleaned, and a scattering mechanism 9 is provided on the outside of the coarse filter cartridge 5.

[0026] Further, refer to Figure 2 and Figure 3 It can be seen that the driving mechanism 7 includes a driving motor 71, the driving motor 71 is installed at the outer end of the filter body 1, and the output end of the driving motor 71 is connected to the driving shaft 72, the surface of the driving shaft 72 is fixedly connected to one end of the connecting rod 73, and the driving motor 71 can make the driving shaft 72 drive the connecting rod 73 to rotate inside the filter body 1.

[0027] Further, refer to Figure 2 and Figure 3 It can be seen that two groups of connecting rods 73 are set on the surface of the driving shaft 72. One group of connecting rods 73 is set to be cylindrical, and the other group of connecting rods 73 is set to be L-shaped. The two groups of connecting rods 73 can respectively drive the cleaning mechanism 8 to clean the coarse filter cartridge 5 and the fine filter cartridge 6.

[0028] Further, refer to Figure 3 and Figure 4It can be seen that the cleaning mechanism 8 includes a fixed frame 81, the other end of the connecting rod 73 is fixedly connected to the fixed frame 81, the inner wall of the fixed frame 81 is welded to one end of the push spring 82, and the other end of the push spring 82 is welded to a cleaning brush rod 83. The elastic force of the push spring 82 itself can facilitate the pushing of the cleaning brush rod 83, so that the cleaning brush rod 83 can be kept in contact with the coarse filter cartridge 5 and the fine filter cartridge 6, thereby improving the cleaning effect.

[0029] Further, refer to Figure 3 and Figure 4 It can be seen that a groove compatible with the cleaning brush rod 83 is opened inside the fixed frame 81, and multiple groups of push springs 82 are welded at equal distances on the inner wall of the groove. By welding multiple groups of push springs 82 on the inner wall of the groove, the cleaning brush rod 83 can be pushed more easily.

[0030] Further, refer to Figure 3 and Figure 4 It can be seen that the cleaning brush rod 83 is inserted into the fixed frame 81 and is fixedly connected to the limiting slider 84 on both sides of one end. The inner wall of the groove is provided with a slide groove that is compatible with the limiting slider 84. By moving the cleaning brush rod 83, the limiting slider 84 can slide in the slide groove, thereby playing the role of limiting and guiding the cleaning brush rod 83.

At the same time, during the filtering process of the coarse filter cartridge 5 and the fine filter cartridge 6, the driving motor 71 can make the driving shaft 72 rotate inside the filter body 1. At this time, the driving shaft 72 can drive the cleaning mechanism 8 to rotate as a whole through the connecting rod 73. When the cleaning mechanism 8 rotates along the surface of the coarse filter cartridge 5 and the inner wall of the fine filter cartridge 6 respectively, the elastic force of the pushing spring 82 itself can push the cleaning brush rod 83 to keep in contact with the coarse filter cartridge 5 and the fine filter cartridge 6, so that the filtered objects on the surface of the coarse filter cartridge 5 and the inner wall of the fine filter cartridge 6 can be cleaned. At the same time, the driving rod 91 can make the multiple sets of fixed columns 92 break up the lumps and impurities in the sewage entering the filter body 1;
