[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A sewage treatment device with a multi-stage filtering function comprises a treatment box 1, a partition 21 is fixedly connected to the inner wall of the treatment box 1, a liquid seepage plate 22 is arranged in the middle of the partition 21, a solid-liquid separation mechanism 3 for easy cleaning is arranged on one side of the treatment box 1, a liquid inlet diversion mechanism 4 matched with the solid-liquid separation mechanism 3 is arranged on one side of the treatment box 1, and a multi-stage filtering component 5 is arranged on the side of the treatment box 1 away from the solid-liquid separation mechanism 3;

[0031] The solid-liquid separation mechanism 3 includes a protrusion 31, an inclined frame 32, a fixing rod 33, a support plate 34, a collecting frame 35, filter holes 36, a filter slot 37 and a drainage filter assembly 38. The protrusion 31 is arranged on the side wall of the processing box 1, the inclined frame 32 is fixedly connected to the inner wall of the processing box 1, a plurality of fixing rods 33 are fixedly connected to the inner wall of the inclined frame 32, the support plate 34 is arranged on the inner wall of the protrusion 31, the collecting frame 35 is bolted to the side wall of the protrusion 31 and is located on the top surface of the support plate 34, a plurality of filter holes 36 are opened on the bottom surface of the collecting frame 35, a plurality of filter slots 37 are opened on the side wall of the support plate 34, and the drainage filter assembly 38 is arranged on the side wall of the protrusion 31.

[0032] Specifically, Figure 4As shown, the drainage filter assembly 38 includes a drainage pipe 381, an inclined cylinder 382, ​​a filter screen 383, a cover 384 and a pull rod 385. The three drainage pipes 381 are through-set at the bottom of the raised portion 31, the inclined cylinder 382 is fixedly connected to the bottom of the drainage pipe 381, the filter screen 383 is movably set inside the inclined cylinder 382, ​​the cover 384 is threadedly connected to the side wall of the inclined cylinder 382, ​​and the pull rod 385 is fixedly connected to the side wall of the filter screen 383 and one end of the pull rod is fixedly connected to the cover 384.

[0033] Specifically, Figure 3 As shown, the multi-stage filter assembly 5 includes a filter frame 51 and a filter plate 52 . The filter frame 51 is arranged in the middle of the processing box 1 , and a plurality of filter plates 52 are arranged on the side wall of the filter frame 51 .

[0034] Specifically, Figure 4 As shown, a mounting plate 61 is fixedly connected to the side wall of the inclined frame 32, and the side wall of the mounting plate 61 contacts the side wall of the processing box 1. Two electric telescopic rods 62 are bolted to the side wall of the mounting plate 61, and a scraper 63 is fixedly connected to the output ends of the two electric telescopic rods 62, and the side wall of the scraper 63 contacts the fixed rod 33.

[0035] Specifically, Figure 3 As shown, a baffle plate 7 is fixedly connected to the inner wall of the processing box 1, and the baffle plate 7 is arranged in a Z shape.

[0036] Specifically, Figure 3 As shown, a sealing plate 8 is fixedly connected to the side wall of the partition 21 , and one end of the sealing plate 8 away from the partition 21 is in contact with the baffle 7 .

[0037] Specifically, Figure 3 As shown, an inspection cover 9 is bolted to the side wall of the processing box 1.

[0038] When in use, sewage enters the treatment box 1 through the liquid inlet diversion mechanism 4 and falls evenly on the inclined frame 32. The sewage passes through multiple fixed rods 33. At this time, the solid matter in the sewage is filtered by the fixed rods 33. Since the inclined frame 32 and the fixed rods 33 are inclined, when the sewage does not enter the treatment box 1, the filtered solid matter slides into the collection frame 35. At the same time, the two electric telescopic rods 62 are started to push the scraper 63 to move to scrape and clean the fixed rods 33, and the filtered solid matter is pushed into the collection frame 35. Part of the sewage follows the solid matter into the collection frame 35. The filter holes 36 and the filter slots 37 filter the sewage and solid matter in the collection frame 35. The filtered sewage enters the drainage pipe 381. When the sewage moves into the inclined cylinder 382, ​​the filter screen 383 filters the sewage again. The filter screen 383 is taken out for cleaning by removing the cover 384 through the pull rod 385. When the sewage moves to the bottom of the treatment box 1, it will first fall on the baffle plate 7, and the sewage will settle between the partition 21 and the treatment box 1. The baffle plate 7 can prevent the falling sewage from causing the sludge settled at the bottom of the treatment box 1 to flow. The precipitated sewage enters the other side of the partition 21 through the seepage plate 22. At this time, the filter frame 51 and multiple filter plates 52 perform multi-stage filtration on the sewage. The electric telescopic rod 62 can be blocked and protected by the cover 8 to prevent water vapor from entering the interior of the electric telescopic rod 62. The interior of the treatment box 1 can be inspected through the inspection cover 9.

[0039] Specifically, Figure 5 As shown, the liquid inlet diversion mechanism 4 includes a liquid inlet pipe 41, a connecting part 42, a connecting pipe 43, a rotating shaft 44 and a diverter blade 45. The three liquid inlet pipes 41 are fixedly connected to the side wall of the processing box 1, the connecting part 42 is fixedly connected to one end of the three liquid inlet pipes 41, the connecting pipe 43 is arranged on the side wall of the connecting part 42, the rotating shaft 44 is bearing-connected to the middle part of the connecting part 42, and the three diverter blades 45 are fixedly connected to the side wall of the rotating shaft 44 and are located inside the connecting part 42.

[0040] When in use, the sewage first enters the connecting part 42 through the connecting pipe 43, and the water flow impacts the diverter blade 45 to rotate the diverter blade 45. Due to the rotation of the diverter blade 45, the sewage evenly enters the three liquid inlet pipes 41 and falls on the inclined frame 32 and the fixed rod 33. In this way, the sewage entering the treatment box 1 can be diverted, and the sewage can evenly fall on the inclined frame 32, and the sewage can evenly contact the inclined frame 32 and the fixed rod 33.

[0041] By adopting the above technical solution, the problem that the existing sewage treatment device is unable to pre-filter the sewage and filter and clean out the solid matter in the sewage is solved, and the solid matter in the sewage enters the treatment box 1 and is difficult to clean.

[0042] Working principle: When the present application is in use, sewage first enters the connecting portion 42 through the connecting pipe 43, and the water flow impacts the diverter blade 45 to rotate the diverter blade 45. Due to the rotation of the diverter blade 45, the sewage evenly enters the three liquid inlet pipes 41 and falls on the inclined frame 32 and the fixed rod 33. The sewage passes through multiple fixed rods 33. At this time, the solid matter in the sewage is filtered by the fixed rod 33. The two electric telescopic rods 62 are started to push the scraper 63 to move to scrape and clean the fixed rod 33, and the filtered solid matter is pushed into the collection frame 35. Part of the sewage follows the solid matter into the collection frame 35. The filter holes 36 and the filter slots 37 filter the sewage and solid matter inside the collection frame 35. The filtered sewage enters the drain pipe 381 and moves to the inclined cylinder 382. The filter screen 383 filters the sewage again. When the sewage moves to the bottom of the treatment box 1, it will first fall on the baffle plate 7. The sewage is precipitated between the partition 21 and the treatment box 1. The precipitated sewage passes through the seepage plate 22 and enters the other side of the partition 21. At this time, the filter frame 51 and the multiple filter plates 52 perform multi-stage filtration treatment on the sewage. In this way, the sewage entering the treatment box 1 can be diverted, and the sewage can be pre-filtered when entering the treatment box 1 to filter out solid matter in the sewage, and the filtered fixed matter can be processed at the same time.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
