Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a sewage treatment device with a self-cleaning function. Background Art

[0002] A sewage treatment plant is a system facility used to treat and purify wastewater from domestic and industrial sources to reduce pollutant emissions and protect the water resource environment. It separates and degrades harmful substances in sewage to meet the prescribed emission standards. Sewage treatment plants are used to realize the resource utilization, reduction and harmlessness of sewage, and are of great significance to maintaining water ecological balance and promoting sustainable development.

[0003] During the process of sewage treatment in sewage treatment equipment, sewage contains a large amount of suspended matter, sediment, biofilm and other solid substances. These substances accumulate on the inner wall of the sewage treatment equipment and form a dirt layer, which affects the treatment capacity and water flow efficiency of the equipment. Therefore, it is often necessary to set cleaning components in the sewage treatment equipment to keep the equipment clean, so as to ensure the normal operation of the sewage treatment system. However, adding cleaning components such as cleaning brushes separately in the sewage treatment equipment often takes up space in the sewage treatment equipment, which reduces the water treatment efficiency of the sewage treatment equipment to a certain extent.

[0004] In view of this, a sewage treatment device with a self-cleaning function is proposed. Utility Model Content

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-6 .

[0026] The utility model discloses a sewage treatment device with a self-cleaning function, comprising a tank body 1 and a cleaning component 2 arranged in the tank body 1, the bottom of the tank body 1 is fixedly connected to a tank bottom 11, the bottom of the tank bottom 11 is fixedly connected to a plurality of legs 12, a tank cover 13 is detachably mounted on the top of the tank body 1, a water inlet 14 is provided on the tank body 1, a water outlet 15 is provided on the tank bottom 11, the cleaning component 2 comprises a cleaning ring 21 which is fitted with and slidably arranged on the inner wall surface of the tank body 1, a biofilm 25 for sewage treatment is detachably mounted on the cleaning ring 21, and the cleaning component 2 is used to clean the inner wall surface of the tank body 1 by moving the cleaning ring 21 up and down after the sewage treatment is completed.

[0027] It should be noted that the biofilm 25 of the sewage treatment device is often provided with a mounting frame to fix the membrane body. In this embodiment, the biofilm 25 is directly installed on the cleaning ring 21, so that the biofilm 25 can move up and down with the cleaning ring 21, thereby improving the contact effect between the biofilm 25 and the sewage. In addition, it also solves the problem of the cleaning component 2 occupying too much water storage space of the sewage treatment device.

[0028] Specifically, the cleaning component 2 also includes a connecting rod 24 fixedly connected to the cleaning ring 21 and a screw 26 rotatably connected to the tank bottom 11. The screw 26 is threadedly connected to a screw sleeve 27, and the screw sleeve 27 is fixedly connected to a swivel 271 with a T-shaped cross section. The swivel 271 is rotatably connected to the connecting rod 24. Figure 5 As shown, an annular groove for rotating the rotating ring 271 is provided on the connecting rod 24, and a motor 28 for driving the screw 26 to rotate is fixedly connected to the bottom of the tank bottom 11. The cleaning ring 21 and the tank body 1 are slidingly arranged, so when the motor 28 rotates, the screw 26 will be driven to rotate. Due to the threaded connection effect of the screw sleeve 27 and the screw 26 and the rotational connection effect of the screw sleeve 27 and the connecting rod 24, the screw sleeve 27 will drive the cleaning ring 21 to move in the vertical direction. During the movement, the screw sleeve 27 rotates relative to the cleaning ring 21.

[0029] Secondly, two sliders 22 with a T-shaped cross-section are fixedly connected to the cleaning ring 21. A slide groove 23 with a size adapted to the slider 22 is opened on the inner wall surface of the tank body 1. The slider 22 and the slide groove 23 are used to limit the cleaning ring 21 so that the cleaning ring 21 can remain stable when moving up and down. When there is dirt in the slide groove 23, the slider 22 will also discharge the dirt by moving from bottom to top. In addition, in this example, the slide groove 23 passes through the top of the tank body 1.

[0030] In addition, a slope 211 is provided on the top of the cleaning ring 21 . The slope 211 is used to improve the cleaning effect of the cleaning ring 21 when the cleaning ring 21 moves upward from the bottom.

[0031] Furthermore, the bottom of the tank cover 13 is fixedly connected with an insert block 131 that is compatible with the slide groove 23. The insert block 131 is used to limit the tank cover 13. The bottom of the tank cover 13 is fixedly connected with a limiting block 132. The limiting block 132 is used to be installed on the top of the screw 26 after the tank cover 13 is installed to keep the screw 26 stable when rotating.

[0032] In the initial state of the device, the cleaning ring 21 should be located at the bottom of the tank body 1. When sewage treatment is carried out, sewage enters from the water inlet 14 and is discharged from the water outlet 15 after being treated by the biofilm 25. When cleaning the tank body 1, clean water enters from the water inlet 14 and is discharged from the water outlet 15. During the cleaning process, the cleaning ring 21 should be cleaned from bottom to top until the cleaning ring 21 moves to the top of the tank body 1 under the action of the motor 28, and the dirt removed from the cleaning ring 21 and the biofilm 25 is removed.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
