[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a sewage treatment device for municipal engineering with multi-layer filtration, including a housing 1, a filter plate 3 is fixedly installed on the left side of the inner wall of the housing 1, a filter pipe 4 is connected to the right side of the housing 1, the right end of the filter pipe 4 is connected to a deodorization and disinfection box 5, a servo motor 6 is fixedly connected to the top of the deodorization and disinfection box 5, the output end of the servo motor 6 is fixedly connected to a rotating column 7, both the front and rear sides of the outer wall of the rotating column 7 are fixedly connected with rotating plates 8, filter elements 9 are fixedly connected to the inner walls of the two rotating plates 8, a water passing box 10 is connected to the right side of the deodorization and disinfection box 5, a filter shell 11 is slidably installed in the inner wall of the water passing box 10, liquid injection valves 12 are connected to both the rear side of the top wall of the deodorization and disinfection box 5 and the left side of the housing 1, and a dredging mechanism 2 is arranged on the front side of the deodorization and disinfection box 5;

[0031] Specifically, sewage is injected through the left liquid injection valve, so that the sewage first passes through the filter plate 3 for preliminary filtration. This step can effectively block impurities with larger particles. The preliminarily filtered sewage will flow into the filter pipe 4 for secondary filtration. This step can further remove fine particles in the sewage and improve the cleanliness of the sewage. At this time, chemical agents are injected through the right liquid injection valve 12, and the oxidizing property and disinfection effect of the agents can be used to deodorize the sewage. On this basis, by starting the servo motor 6, the rotating column 7 drives the rotating plates 8 and the filter elements 9 to rotate. Under the action of centrifugal force, the mixing rate of the chemical agents and the sewage is controlled, thereby improving the working efficiency of sewage deodorization and disinfection, making the sewage treatment faster and more thorough. Finally, the treated sewage flows into the water passing box 10 again and is finally filtered through the filter shell 11. This stage of filtration can effectively remove residual agents and fine particles in the sewage and ensure the quality of the effluent. Through this series of steps, the sewage can achieve the purpose of multi-stage filtration and deodorization and disinfection.

[0032] Referring to Figure 1 and Figure 3 , the dredging mechanism 2 includes a protective shell 201, the rear side of the protective shell 201 is fixedly installed on the front side of the deodorization and disinfection box 5, a blower 202 is fixedly installed on the rear side of the inner wall of the protective shell 201, the output end of the blower 202 is connected to a delivery pipe 203, the left delivery pipe 203 is connected to an annular spray pipe 204, the outer wall of the annular spray pipe 204 is fixedly connected to the middle of the inner wall of the housing 1, the right end of the right delivery pipe 203 is connected to a spray head 206, the bottom wall of the spray head 206 is fixedly connected to the left side of the top wall of the water passing box 10, a sewage discharge valve 13 is connected to the left side of the bottom wall of the housing 1; a rubber ring 205 is fixedly installed on the left end of the outer wall of the left delivery pipe 203, and the outer wall of the rubber ring 205 is fixedly connected to the front side of the housing 1;

[0033] Specifically, the blower 202 is started by extracting external air flow, introducing the air flow into the delivery pipe 203, and then delivering it to the annular nozzle 204 and the nozzle 206 respectively. The high-pressure air flow in this step lays the foundation for the subsequent treatment steps. The flow of the high-pressure air flow drives the left-side air flow, enabling it to have sufficient force to dredge the blocked filter plate 3. This blockage phenomenon is a common problem in the sewage treatment process, but it can be effectively solved by starting the blower 202. Under the impact of the air flow, the large-particle impurities on the filter plate 3 are smoothly discharged, which is a crucial moment for the sewage discharge valve 13 to play its role. The right-side air flow can dredge the inner wall of the filter housing 11 through the nozzle 206. Through this series of operations, the throughput of sewage treatment has been significantly improved. This means that the impact of the blockage phenomenon on sewage treatment has been minimized, thereby improving the effect of sewage treatment.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 As shown in, a control switch 15 is fixedly connected to the left side of the protective housing 201. The control switch 15 is electrically connected to the blower 202 and the servo motor 6 respectively; a protective housing 16 is arranged on the left side of the control switch 15. The right side of the protective housing 16 is rotatably connected to the left side of the protective housing 201 through a hinge; support frames 17 are fixedly connected to the front and rear sides of the outer housing 1 and the deodorization and disinfection box 5. Corner guards 18 are fixedly installed on the front and rear sides of the two support frames 17;

[0035] Specifically, through the control switch 15 that is electrically connected to the blower 202 and the servo motor 6 respectively, the control switch 15 can complete the opening and closing of the device. Through the protective housing 16, the control switch 15 can be protected and prevent accidental touch.

[0036] Referring to Figure 2 and Figure 3 As shown in, a plurality of heat dissipation slots 207 are equidistantly arranged on the front side of the protective housing 201; a handle 14 is fixedly connected to the top wall of the filter housing 11, and an inclined surface is arranged on the left side of the top wall of the water connection tank 10;

[0037] Specifically, through the plurality of heat dissipation slots 207, the heat dissipation effect of the blower 202 is improved. Through the handle 14, it is convenient to pull out the filter housing 11.

[0038] Working principle: When starting sewage treatment, sewage is injected through the left liquid injection valve 12, enabling the sewage to pass through the filter plate 3 for preliminary filtration, blocking larger particulate impurities. Then, the preliminarily filtered sewage flows into the interior of the deodorization and disinfection tank 5 through the filter pipe 4 for secondary filtration. Chemical agents can be injected through the right liquid injection valve 12. By starting the servo motor 6, the rotating column 7 drives the rotating plate 8 and the filter element 9 to rotate, so that under the action of centrifugal force, the mixing rate of the chemical agents and the sewage can be controlled, thereby improving the working efficiency of sewage deodorization and disinfection. The treated sewage flows back into the through-water tank 10 and completes the final filtration through the filter housing 11, achieving the purpose of multi-stage filtration and deodorization and disinfection. And by starting the blower 202 to extract external air flow, the air flow enters the annular spray pipe 204 and the nozzle 206 respectively through the two delivery pipes 203. Under the flow of high-pressure air, the blocked filter plate 3 on the left can be dredged, and the dredged large particulate impurities can be discharged through the sewage discharge valve 13. The air flow on the right can dredge the inner wall of the filter housing 11 through the nozzle 206, thereby increasing the sewage treatment throughput, reducing the situation where the filter plate 3 is blocked and affecting sewage treatment, and further improving the sewage treatment effect.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
