DETAILED DESCRIPTION

[0019] 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 of the embodiments.

[0020] Reference Figure 1-4 A high-efficiency energy-consuming backwashing device for sewage treatment comprises a sewage treatment tank 1, a partition plate 2 is fixedly installed between the inner walls of the sewage treatment tank 1, a plurality of filter cartridges 18 are movably installed on the partition plate 2, a plurality of circular holes are opened on the top of the partition plate 2, the circular holes are adapted to the filter cartridges 18, a support plate 3 is fixedly installed in the circular holes, a hydraulic turbine 4 is rotatably installed on the support plate 3, a rotating rod 5 is fixedly installed on the top of the hydraulic turbine 4, a plurality of brush plates 6 are fixedly installed on the outer side of the rotating rod 5, bristles are arranged on one side of the brush plate 6, and the bristles are in contact with the inner surface of the filter cartridge 18 The wall is movably abutted, a rotating tube 7 is rotatably installed on the partition plate 2, the outer side of the rotating tube 7 is connected with a curved tube 9, the top of the curved tube 9 is connected with a cover body 8, and a rotating shaft 10 is fixedly installed on the bottom of the rotating tube 7. A box body is fixedly installed at the bottom of the sewage treatment tank 1, and a reduction motor 11 is arranged in the box body. The output shaft of the reduction motor 11 and the outer side of the rotating shaft 10 are fixedly sleeved with bevel gears, and the two bevel gears are meshed with each other. A drain pipe 12 is rotatably sealed and installed on the top of the rotating tube 7. One end of the drain pipe 12 extends to the outside of the sewage treatment tank 1 and is connected with a drain valve 13.

[0021] It should be noted that the blades of the hydraulic turbine 4 are usually designed to be flat and fan-shaped. This design can make the water flow generate greater pressure on the blades, so that the hydraulic turbine 4 rotates. Usually, the rotation of the hydraulic turbine 4 is single, so that the rotating rod 5 will only rotate during backwashing, and the rotating rod 5 will not rotate during the normal sewage filtering process, so as to avoid the brush plate 6 from rotating for a long time and causing wear to the inner wall of the filter cartridge 18.

[0022] In the utility model, a feeding hole is provided at the top of the sewage treatment tank 1, and the top end of the filter cartridge 18 is movably engaged in the corresponding feeding hole. An external cylinder 14 is provided above the feeding hole, and a cover body 15 is movably engaged in the external cylinder 14 through a latch. The feeding hole is closed and the filter cartridge 18 is pressed and fixed by the cooperation of the cover body 15 and the outer cylinder 14, and the filter cartridge 18 is conveniently taken out for replacement.

[0023] In the present invention, a fixing plate 16 is fixedly installed at the bottom of the cover body 15 , and a rotation groove is provided at the bottom of the fixing plate 16 , and the rotation rod 5 is slidably installed in the rotation groove to support the rotation rod 5 .

[0024] In the utility model, a plurality of limiting cylinders 17 are fixedly installed on the top of the partition plate 2 , and the filter cylinder 18 is slidably installed in the corresponding limiting cylinder 17 , which plays a role of limiting the filter cylinder 18 .

[0025] In the utility model, the outside of the sewage treatment tank 1 is connected with an inlet pipe 19 and an outlet pipe 20. The inlet pipe 19 is located below the partition plate 2, and the outlet pipe 20 is located above the partition plate 2, which is convenient for guiding the sewage and realizing the sewage filtering function.

[0026] In the utility model, a plurality of supporting feet are fixedly installed on the bottom of the sewage treatment tank 1, and the plurality of supporting feet are centrally symmetrically arranged.

[0027] The working principle of the utility model is as follows: sewage is pumped into the sewage treatment tank from the water inlet pipe 19 through the water pump, and the sewage enters the filter cartridge 18 through the circular hole. The solid waste in the sewage is filtered by the filter cartridge 18, and the filtered water is discharged through the drain pipe 12. When the filter cartridge 18 needs to be backwashed, the reduction motor 11 is started, and the output shaft of the reduction motor 11 drives the rotating shaft 10 to rotate, thereby driving the rotating pipe 7 and the curved pipe 9 to rotate together, and the curved pipe 9 drives the cover body 8 to rotate to the bottom of the filter cartridge 18 that needs to be washed, and the sewage discharge valve 13 is started. The sewage in the filter cartridge 18 is discharged through the sewage discharge valve 13. At this time, a pressure difference is formed inside and outside the filter cartridge 18, and the waste attached to the inner wall of the filter cartridge 18 is washed away. When the sewage in the filter cartridge 18 flows through the circular hole, it drives the hydraulic turbine 4 to rotate, thereby driving the rotating rod 5 and multiple brush plates 6 to rotate together, and the brush plate 6 brushes the inner wall of the filter cartridge 18, so as to further improve the cleaning effect of the solid waste.

Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
