DETAILED DESCRIPTION

[0025] 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.

[0027] The guide structure 3 includes six supporting sliders 301 installed at equal distances on the circumference of the rotating shaft 2 by bolts. The outer top ends of two supporting sliders 301 at the same level among the six supporting sliders 301 are installed in two slide grooves 303 inside the sleeve ring 302 by plugging. The three sleeve rings 302 are provided with filtering structures 4.

[0028] The filter structure 4 includes a filter layer 1 401, a filter layer 2 402, and a filter layer 3 403;

[0029] Two cleaning scrapers 5 are symmetrically installed on the circumferential side of the rotating shaft 2 and on the top of the filter layer 1 401, the filter layer 2 402, and the filter layer 3 403 through bolts, and vibration motors 7 are installed on the bottom ends of the filter layer 1 401, the filter layer 2 402, and the filter layer 3 403 through bolts.

[0030] In this embodiment, a sewage outlet 6 is provided on one side of the filter box 1 and located at the top of the filter layer 1 401 , the filter layer 2 402 , and the filter layer 3 403 .

[0031] By adopting the above scheme, sewage outlets 6 are opened on one side of the filter box 1 and respectively located at the top of filter layer 1 401, filter layer 2 402, and filter layer 3 403, so that sewage can be discharged through the corresponding sewage outlets 6, avoiding the problem of stains clogging the sewage outlets 6.

[0032] In this embodiment, a balance bar 8 is inserted at the top of the rotating shaft 2 via a rolling bearing, and both ends of the balance bar 8 are mounted on a liquid inlet 9 opened at the top of the filter box 1 by welding.

[0033] By adopting the above scheme, a balance rod 8 is inserted into the top of the rotating shaft 2 through a rolling bearing, and both ends of the balance rod 8 are installed on the liquid inlet 9 opened on the top of the filter box 1 by welding, so that the balance rod 8 can perform balanced support, effectively improve the rotational stability, and also facilitate the liquid injection through the liquid inlet 9, effectively improving the filtering and feeding efficiency.

[0034] In this embodiment, a drain port 10 is welded through the bottom end of one side of the filter box 1 , and a valve is inserted into the drain port 10 .

[0035] By adopting the above solution, a drain port 10 is welded through the bottom end of one side of the filter box 1, and a valve is inserted into the drain port 10 to achieve drainage through the drain port 10, effectively improving the smoothness of drainage.

[0036] In this embodiment, support legs 11 are evenly mounted on the circumference of the bottom end of the filter box 1 by bolts.

[0037] By adopting the above solution, the support legs 11 are evenly installed on the circumference of the bottom end of the filter box 1 by bolts, so that balanced support behavior can be performed by the three support legs 11 to avoid the problem of tilting of the bottom end of the filter box 1.

[0038] In this embodiment, the bottom end of the rotating shaft 2 extends through the filter box 1 and is plugged with a motor 12 via a connecting key. The top of the motor 12 is mounted on the filter box 1 via bolts.

[0039] By adopting the above scheme, the bottom end of the rotating shaft 2 is extended through the filter box 1, and the motor 12 is plugged in through the connecting key. The top of the motor 12 is installed on the filter box 1 by bolts, so that the motor 12 drives the rotating shaft 2 to rotate synchronously, thereby improving the efficiency of scraping impurities.

[0040] In this embodiment, filter layer 1 401 is made of activated carbon particles, filter layer 2 402 is made of ceramic particles, and filter layer 3 403 is made of cotton fibers. The interiors of filter layer 1 401, filter layer 2 402, and filter layer 3 403 are all connected to the outside of the corresponding sleeve ring 302 through rolling bearings.

[0041] By adopting the above scheme, by making the filter layer 1 401 from activated carbon particles, the filter layer 2 402 from ceramic particles, and the filter layer 3 403 from cotton fibers, layer-by-layer filtration is achieved, and the filtering capacity is effectively improved. In addition, the interiors of the filter layer 1 401, the filter layer 2 402, and the filter layer 3 403 are all connected to the outside of the corresponding sleeve ring 302 through rolling bearings, so that when the rotating shaft 2 rotates, the filter layer 1 401, the filter layer 2 402, and the filter layer 3 403 will not rotate with it, thereby avoiding leakage problems.

[0042] In this embodiment, baffles are welded to the outer bottom ends of the three sewage outlets 6 .

[0043] By adopting the above solution, baffles are welded at the outer bottom ends of the three sewage outlets 6, so as to facilitate the long-distance discharge of impurities.

[0044] In the utility model, when in use, waste water is added to the interior of the filter box 1 through the liquid inlet 9. Due to gravity and the vibration transmission of the vibration motor 7, the waste water will pass through the filter layer 1 401, the filter layer 2 402, and the filter layer 3 403 in sequence, so as to achieve the purpose of filtering impurities layer by layer. Large particles of impurities will adhere to the filter layer 1 401, the filter layer 2 402, and the filter layer 3 403. The motor 12 drives the six cleaning scrapers 5 on the rotating shaft 2 to rotate synchronously, scrape off the impurities, and discharge them through the sewage outlet 6, thereby effectively improving the cleaning ability and avoiding the problem of impurities clogging the filter structure.
