[0025] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a sewage treatment device with a self-cleaning function through improvement. The technical solution of the utility model is:

[0027] like Figure 1-Figure 5 As shown, a sewage treatment device with a self-cleaning function includes a filter chamber 1, a cleaning assembly is arranged inside the filter chamber 1, and the cleaning assembly includes a pair of racks 211 respectively fixedly connected to the two sides of the bottom of the filter chamber 1, and the two sides of the filter chamber 1 near the bottom are provided with gears 21 meshing with the racks 211, and a brush roller 20 is fixedly connected between the two gears 21. The gear 21 moves along the rack 211, and can drive the brush roller 20 to rotate, so as to automatically clean the impurities at the bottom of the device, thereby reducing the cleaning time of the device and helping to improve the sewage treatment efficiency of the device, and also includes;

[0028] The movable component includes an activated carbon plate 13 rotatably connected to both sides of the interior of the filter chamber 1, the activated carbon plate 13 includes a connecting frame, and an activated carbon layer is fixedly arranged in the connecting frame. The side of the activated carbon plate 13 away from the brush roller 20 penetrates the filter chamber 1 and is fixedly connected to a threaded rod 8, and a movable block 7 is threadedly connected to the threaded rod 8. The rotation of the threaded rod 8 can drive the activated carbon plate 13 to rotate, so as to clean the activated carbon plate 13 and improve the sewage treatment effect of the equipment.

[0029] Furthermore, the brush roller 20 is rotatably connected to the sleeve 22 on both sides close to the gear 21, the top of the sleeve 22 is fixedly connected to the piston rod 16, the top of the piston rod 16 is slidably connected to the piston cylinder 24, a spring 25 is fixedly connected between the piston cylinder 24 and the piston rod 16, the top of the piston cylinder 24 is fixedly connected to the brush plate 15, the two sides of the brush plate 15 are slidably connected to the inner wall of the adjacent filter bin 1, and the bottom of the filter bin 1 is inclined. When the brush roller 20 moves, the spring 25 is extended and retracted to drive the piston rod 16 to extend and retract, so that the brush plate 15 can continuously clean the activated carbon plate 13.

[0030] Furthermore, a connecting plate 17 is fixedly connected between the two piston cylinders 24, a reciprocating shaft block 171 is fixedly connected to the middle part of the connecting plate 17, two guide rods 14 are fixedly connected to the two sides near the bottom of the filter bin 1, a reciprocating screw 19 rotatably connected to the filter bin 1 is arranged between the two guide rods 14, the connecting plate 17 is slidably connected to the guide rod 14, the reciprocating shaft block 171 is adapted to the reciprocating screw 19, a servo motor 18 is fixedly connected to one side of the filter bin 1 near the connecting plate 17, the output shaft of the servo motor 18 is fixedly connected to the reciprocating screw 19, the servo motor 18 is started to drive the reciprocating screw 19 to rotate, so that the reciprocating shaft block 171 moves with the cleaning assembly to clean the activated carbon plate 13 and the bottom of the filter bin 1, the setting of the guide rod 14 helps to improve the stability of the operation of the cleaning assembly and plays a role in limiting the movement of the connecting plate 17.

[0031] Furthermore, a groove plate 10 rotatably connected to one end of the threaded rod 8 is fixedly connected to one side of the filter bin 1 away from the connecting plate 17, and the top of the groove plate 10 is slidably matched with the moving block 7. A servo motor 9 is fixedly connected to one side of the groove plate 10, and the output shaft of the servo motor 9 is fixedly connected to the threaded rod 8. The thread on the threaded rod 8 adopts a large-pitch thread, and rotation requires multiple turns to achieve the flipping of the activated carbon plate 13. The servo motor 9 is started to drive the threaded rod 8 to rotate, so that the moving block 7 slides in the groove plate 10.

[0032] As a further solution of the utility model, a filter screen 12 is slidably connected to one side near the top of the filter bin 1, and grooves are provided at the corners of the filter bin 1. A spring 23 is fixedly connected between the groove and the filter screen 12. When liquid falls on the filter screen 12, the spring 23 on one side will contract to make the filter screen 12 vibrate, thereby improving the pre-filtration effect of sewage. When the activated carbon plate 13 rotates, it will push the filter screen 12, causing the filter screen 12 to vibrate, which is conducive to the impurities on the filter screen 12 falling to the bottom of the filter bin 1.

[0033] Furthermore, a square hole 3 is opened on the same side of the filter bin 1 and the moving block 7, and an L-shaped plate 61 matching the square hole 3 is slidably connected to the inner wall of the square hole 3, a cross plate 6 is fixedly connected between one side of the L-shaped plate 61 and the moving block 7, and the other side of the L-shaped plate 61 is fitted with the bottom of the adjacent filter screen 12, and guide rods 4 are slidably connected on both sides of the cross plate 6, one end of the guide rod 4 is fixedly connected to the filter bin 1, and the other end of the guide rod 4 is fixedly connected to the limiting block 5, and the movement of the moving block 7 drives the cross plate 6 to move, so that the L-shaped plate 61 is away from the filter screen 12, so that a gap is generated between the filter screen 12 and the filter bin 1, so that impurities on the filter screen 12 can fall, and the guide rod 4 plays a role of limiting and supporting.

[0034] As a further solution of the utility model, the top of the filter bin 1 is fixedly connected to a liquid inlet pipe 2, and the filter bin 1 and the movable block 7 are connected to a filter body 11 on the same side through a hinge. The sewage enters the filter bin 1 through the liquid inlet pipe 2, and the filtered sewage is discharged after being filtered through the filter body 11. When cleaning impurities, the filter body 11 is opened to clean the impurities.

[0035] The specific working method is as follows: during filtration, sewage enters the filter chamber 1 through the liquid inlet pipe 2, and the sewage falls to the filter screen 12, which makes the filter screen 12 vibrate, so as to improve the filtering effect. The sewage filtered by the filter screen 12 falls to the activated carbon plate 13, and the activated carbon plate 13 adsorbs impurities in the sewage and then filters and discharges it through the filter body 11. During cleaning, the filter body 11 is opened, and the threaded rod 8 rotates to drive the activated carbon plate 13 to rotate, while the moving block 7 moves, so that the cross plate 6 drives the L-shaped plate 61 away from the filter screen 12, so that the filter screen 12 and the filter screen 12 are close to each other. A gap is created between the bins 1. At the same time, the activated carbon plate 13 will resist the filter screen 12 when it rotates, causing the filter screen 12 to vibrate, which is convenient for impurities to fall. After the threaded rod 8 rotates multiple times, the activated carbon plate 13 is flipped over. At this time, the reciprocating screw 19 rotates to drive the cleaning assembly to move along the rack 211, so that the brush plate 15 cleans the activated carbon plate 13. At the same time, the rotating brush roller 20 cleans the bottom of the filter bin 1, and the spring 25 will be adjusted according to the telescopic length of the piston rod 16 to improve the cleaning effect.

[0036] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
