DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further elaborates on the present utility model in conjunction with embodiments:

[0025] As Figures 1-5 shown, the present utility model provides a multi - stage sewage treatment device, including a treatment tank 1. A support frame 2 is fixedly installed at the right end of the treatment tank 1. A crushing mechanism 3 is installed at the upper end of the support frame 2. A grading and filtering mechanism 4 is installed inside the left end of the treatment tank 1. A drain pipe 5 which is connected and communicated is fixedly connected to the left end of the treatment tank 1. On the inner walls of the middle part on the right side of the treatment tank 1, limiting frames 6 are symmetrically and fixedly connected. A filter box 7 is movably installed at the upper end of the limiting frame 6. On both sides of the upper end of the filter box 7, handles 8 are symmetrically and fixedly connected. On the lower side of the right end of the treatment tank 1, rotating columns 9 are symmetrically and rotatably installed. At the top of the rotating column 9, a mounting disc 10 is fixedly connected. Between the mounting discs 10, three heating rods 11 which are equally spaced are fixedly installed. On the right front side of the treatment tank 1, a first support plate 12 is fixedly connected. Inside the first support plate 12, a first motor 13 is fixedly installed. The output end of the first motor 13 is drivingly installed with a first gear 14. A second gear 15 which meshes with the first gear 14 is rotatably installed below the first gear 14.

[0026] A valve is fixedly installed on the drain pipe 5.

[0027] The top of the front rotating column 9 is drivingly installed with the rear end of the second gear 15.

[0028] Through the limiting frame 6, it is convenient to limit and place the filter box 7, making it not easy to fall. Through the filter box 7, the garbage in the sewage can be filtered to prevent the garbage from entering the treatment tank 1. By pulling up the handle 8, it is convenient to take out the filter box 7 from the limiting frame 6 for cleaning its interior.

[0029] As Figure 4 shown, the crushing mechanism 3 includes a crushing frame 31. The lower end of the crushing frame 31 is fixedly connected to the upper end of the support frame 2. On the lower sides of the front and rear ends of the crushing frame 31, side frames 32 are symmetrically and fixedly installed. On the upper side of the front end of the crushing frame 31, a second support plate 33 is fixedly connected. Inside the second support plate 33, a second motor 34 is fixedly connected. Inside the crushing frame 31, a rotating rod 35 is rotatably installed. An external crushing spiral blade 36 is fixedly sleeved on the rotating rod 35. On the lower right side inside the crushing frame 31, a diversion platform 37 is fixedly installed. On the left lower end of the crushing frame 31, a communicating diversion cover 38 is fixedly installed.

[0030] The inner sides of the side frames 32 are fixedly connected to the front and rear sides of the right end of the treatment tank 1. The output end of the second motor 34 is drivingly installed with the top of the rotating rod 35.

[0031] The surface of the diversion platform 37 is an inclined surface, and the inclined surface faces the diversion cover 38.

[0032] Through the diversion platform 37, the garbage crushed by the sewage box can be guided to the diversion cover 38, which facilitates pouring the sewage and the crushed garbage into the filter box 7 by using the diversion cover 38.

[0033] Through the crushing structure, the sewage can be effectively and comprehensively treated. In particular, the solid garbage contained in the sewage can be fully crushed. In this way, it can effectively avoid the bad situation of the solid garbage blocking the filter plate, and can also well prevent the sharp-shaped solid garbage from piercing the pipeline, thus greatly reducing the possibility of pipeline leakage caused by solid garbage.

[0034] As Figure 5 shown, the grading filtration mechanism 4 includes three groups of through slots 41, which are equidistantly arranged at the upper left end of the treatment tank 1. The front and rear inner walls at the left end of the treatment tank 1 are equidistantly distributed with positioning slots 42. The upper side of the through slot 41 is movably installed with an end plate 43. In the middle of the upper side of the end plate 43, a handle 44 is fixedly installed. A positioning block 45 is slidably installed inside the positioning slot 42. The lower ends of the end plate 43 are fixedly installed with a first filter plate 46, a second filter plate 47, and a third filter plate 48 from right to left respectively.

[0035] The inner side of the positioning block 45 is fixedly connected to the front and rear end faces of the three filter plates.

[0036] The first filter plate 46, the second filter plate 47, and the third filter plate 48 are a PP cotton filter plate, an activated carbon filter plate, and a RO reverse osmosis membrane filter plate respectively.

[0037] Through the PP cotton filter plate, the sediment impurities in the sewage can be effectively filtered. Through the activated carbon filter plate, the pigments and organic matters in the sewage can be effectively filtered. Through the RO reverse osmosis membrane filter plate, the bacteria, viruses, and heavy metals in the sewage can be effectively filtered. By pulling up the handle 44, it is convenient to take out the three filter plates from the treatment tank 1, which is convenient for cleaning and replacement. In this way, it can effectively prevent the filter plates from being blocked due to excessive accumulation of impurities, thus ensuring the smooth progress of the filtration process, and further greatly improving the use effect of the entire filtration mechanism.

[0038] Next, the working principle of the multi-stage sewage treatment equipment will be specifically described.

[0039] As Figures 1-5As shown, when the multi-stage sewage treatment equipment is in use and sewage needs to be treated, the sewage can be first poured into the crushing frame 31. Immediately afterwards, the second motor 34 is started. The second motor 34 drives the crushing spiral blade 36 to rotate through the rotating rod 35, so as to crush the solid waste in the sewage in the crushing frame 31. Subsequently, the crushed waste and the sewage will flow through the diversion cover 38 into the filter box 7. The filter box 7 can be used to preliminarily filter the sewage, separating the crushed waste from the sewage. Then the sewage will flow into the treatment tank 1. At this time, the first motor 13 can also be started. The first motor 13 drives the first gear 14 to rotate, so that the first gear 14 can drive the rotating column 9 to rotate through the meshing second gear 15, and the rotating column 9 drives the heating rod 11 to rotate synchronously through the mounting plate 10. At this time, the heating rod 11 is started. After the heating rod 11 is powered on, it generates heat and heats the sewage, making the impurities in the sewage easier to decompose when encountering high temperature. And when the heating rod 11 rotates in the water, it will stir the sewage, disrupt the impurities contained in the sewage, and make the sewage easier to treat. Finally, after the sewage is filtered in stages by three groups of filter plates, it can be discharged through the drain pipe 5, thus completing the staged filtration operation of the sewage and improving the practicability of the device.

[0040] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
