Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a multi-layer filtration wastewater treatment device. Background Technology

[0002] Wastewater refers to water discharged during production and daily life activities. It usually contains various harmful substances, such as organic matter, inorganic matter, and microorganisms, and has lost its original function.

[0003] Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. In the existing technology, most wastewater treatment generally uses filter screens to simply filter wastewater, which cannot fully filter the wastewater and thus affects the wastewater treatment effect and is not practical enough. Therefore, it is necessary to redesign multi-layer filtration wastewater treatment devices to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer filtration wastewater treatment device.

A first filter plate is fixedly installed inside the treatment tank. A reciprocating screw is fixedly installed on the inner wall of the treatment tank. A motor connected to the reciprocating screw is fixedly installed on the outer wall of the treatment tank. A screw sleeve is threadedly installed on the outer wall of the reciprocating screw via a limiting mechanism. A cleaning brush is fixedly installed on the bottom wall of the screw sleeve via a connecting mechanism. A baffle that mates with the reciprocating screw is fixedly installed inside the treatment tank. A cleaning opening is provided on the outer wall of the treatment tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A multi-layer filtration wastewater treatment device includes a treatment tank 1. A connecting pipe 3 is fixedly connected to the upper end face of the treatment tank 1 through an inlet 2. A first filter plate 4 is fixedly installed inside the treatment tank 1. A reciprocating screw 5 is fixedly installed on the inner wall of the treatment tank 1. A motor 6 connected to the reciprocating screw 5 is fixedly installed on the outer wall of the treatment tank 1. A screw sleeve 8 is threadedly installed on the outer wall of the reciprocating screw 5 through a limiting mechanism. The limiting mechanism includes a limiting rod 7 fixedly installed inside the treatment tank 1. The limiting rod 7 slides through the screw sleeve 8 and can limit the screw sleeve 8, so that the screw sleeve 8 can only move axially along the outer wall of the reciprocating screw 5. A cleaning brush 10 is fixedly installed on the bottom wall of the screw sleeve 8 through a connecting mechanism. The connecting mechanism includes a connecting rod 9 fixedly installed on the bottom wall of the screw sleeve 8. The end of the connecting rod 9 is fixedly connected to the outer wall of the cleaning brush 10.

[0023] Inside the treatment box 1, a baffle 11 is fixedly installed to cooperate with the reciprocating screw 5. The baffle 11 can block the sewage and prevent impurities in the sewage from flowing through the reciprocating screw 5 and affecting its operation. A cleaning opening is provided on the outer wall of the treatment box 1. A collection box 12 is fixedly installed on the outer wall of the treatment box 1. A first collection box 13 is slidably installed on the outer wall of the collection box 12 through a first sliding opening. A fixing plate 14 is fixedly installed on the outer wall of the treatment box 1. A connecting block 16 is fixedly installed on the bottom wall of the fixing plate 14 through a telescopic mechanism. The telescopic mechanism includes an electric push rod 15 fixedly installed on the bottom wall of the fixing plate 14. The telescopic end of the electric push rod 15 is fixedly connected to the upper end face of the connecting block 16. A cover plate 18 is fixedly installed on the outer wall of the connecting block 16 through a connecting rod 17. A second filter plate 20 is slidably installed on the outer wall of the treatment box 1 through a second sliding opening.

[0024] A sealing gasket 19 that mates with the cleaning opening is fixedly installed on the inner wall of the cover plate 18. A sealing ring 21 that mates with the second sliding opening is fixedly installed on the outer wall of the treatment box 1. Both the sealing gasket 19 and the sealing ring 21 are made of vulcanized rubber. Vulcanized rubber refers to rubber that has been vulcanized and has properties such as non-stickiness and resistance to breakage. Most rubber products are made of this type of rubber, which has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents. A second collection box 22 is slidably installed on the outer wall of the treatment box 1 through a third sliding opening. An activated carbon cotton board 24 is slidably installed inside the second collection box 22 through a support mechanism. The support mechanism includes support plates 23 fixedly installed on the inner walls of both sides of the second collection box 22. The activated carbon cotton board 24 is slidably installed on the upper surface of the two support plates 23. The activated carbon cotton board 24 is an activated carbon filter material made by melting activated carbon particles into liquid powdered carbon and then attaching it to a medium. It combines the adsorption performance of activated carbon with the formability and strength of the medium, and has good adsorption performance, good formability, high strength, and low airflow resistance.

[0025] In use, wastewater is discharged into the treatment tank 1 through the connection pipe 3 and the inlet 2. The wastewater then undergoes preliminary filtration through the first filter plate 4, where larger impurities remain on the surface. The pre-filtered wastewater then flows onto the second filter plate 20, which reabsorbs impurities, further treating the wastewater. Subsequently, the wastewater flows through the gaps in the second filter plate 20 into the activated carbon cotton plate 24 inside the second collection box 22. The activated carbon cotton plate 24 effectively removes organic matter, odors, and other impurities from the water through its strong adsorption capacity, thus purifying the water. The purified wastewater flows into the second collection box 22 and undergoes multiple filtrations to improve the wastewater treatment effect. The treated wastewater can be easily removed by pulling the second collection box 22 out through the third sliding opening using the handle. The sliding activated carbon cotton plate 24 can be easily replaced.

[0026] Meanwhile, during the wastewater filtration process, the motor 6 drives the reciprocating screw 5 to rotate. When the reciprocating screw 5 rotates, it can move the screw sleeve 8 through cooperation with the limit rod 7. When the screw sleeve 8 moves, it can move the cleaning brush 10 on the surface of the first filter plate 4 through cooperation with the connecting rod 9. Thus, the cleaning brush 10 can clean the impurities on the surface of the first filter plate 4, avoiding the accumulation of impurities and clogging of the first filter plate 4. Under the extension and retraction of the electric push rod 15, the cover plate 18 can be opened through the cooperation of the connecting block 16 and the connecting rod 17. Thus, the cleaned impurities can be swept into the first collection box 13 inside the collection box 12 through the cleaning opening, and then the first collection box 13 can be pulled out through the first sliding opening for centralized treatment of impurities. The second filter plate 20 can be pulled out through the second sliding opening for convenient cleaning.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
