[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 6 As shown, a waste liquid treatment device of this utility model includes a support frame 1, a bearing box 3 fixedly installed at the bottom of the support frame 1, a connecting pipe 4 fixedly connected to one side of the bearing box 3, and a treatment box 42 fixedly connected to one end of the connecting pipe 4; it also includes a waste removal mechanism for cleaning up solids generated during waste liquid treatment; the waste removal mechanism includes a medicine storage box 44 fixedly installed at the top of the treatment box 42, a first downflow pipe 45 fixedly connected to the bottom of the treatment box 42, a fourth motor 453 fixedly installed on one side of the first downflow pipe 45, the output shaft of the fourth motor 453 passing through the inner cavity of the first downflow pipe 45 and fixedly connected to a waste discharge plate 454, a second downflow pipe 46 fixedly connected to the bottom of the first downflow pipe 45, a waste discharge pipe 452 fixedly installed on one side of the first downflow pipe 45, a protrusion 456 fixedly installed on the inner wall of the waste discharge pipe 452, and a baffle 455 and a drain plate 457 fixedly installed on the inner wall of the first downflow pipe 45.

[0029] When cleaning up waste liquid, it is necessary to extract the solids from the waste liquid, and the solids and liquids need to be discharged and collected separately. During discharge, the extracted solids are prone to clogging the sewage pipe.

[0030] In use, the waste liquid is first poured into the carrier tank 3. In the carrier tank 3, the larger solids in the waste liquid can be filtered out. The filtered waste liquid enters the treatment tank 42 through the connecting pipe 4. At this time, the reactants are output into the treatment tank 42 through the storage tank 44. The reactants come into contact with the waste liquid and can precipitate the impurities in the waste liquid and make the impurities form larger solids. After the waste liquid in the treatment tank 42 is treated, the waste liquid and solids are discharged through the first downflow pipe 45. During the discharge process, the treated waste liquid will directly enter the second downflow pipe 46 through the first downflow pipe 45, while the solids precipitated in the waste liquid will pass through the top of the protrusion 456. At the same time, in order to prevent the solids from clogging in the first downflow pipe 45, the output shaft of the fourth motor 453 drives the waste plate 454 to rotate, which can push the solids to flow continuously in the inner cavity of the first downflow pipe 45, thus avoiding the problem of the waste liquid treatment device being blocked.

[0031] Furthermore, such as Figure 2 As shown, the inner wall of the support frame 1 is provided with a sliding groove 11, and a sliding plate 2 is slidably installed on the inner surface of the sliding groove 11. Two first motors 21 are fixedly installed on the top of the sliding plate 2. The output shaft of the first motor 21 is fixedly connected to a first gear 22. Two racks 23 are fixedly installed on the top of the support frame 1, and the two racks 23 mesh with the two first gears 22 respectively.

[0032] A second motor 24 is fixedly installed on the top of the slide plate 2. The output shaft of the second motor 24 is fixedly connected to a winding reel 25. A connecting line 26 is wound around the outer surface of the winding reel 25. One end of the connecting line 26 is fixedly connected to a filter box 27.

[0033] In use, the filter box 27 is first placed inside the bearing box 3. Then, the output shaft of the second motor 24 drives the winding reel 25 to rotate, so that the connecting wire 26 is wound around the outer surface of the winding reel 25, which can lift the filter box 27. At this time, the solids in the waste liquid will be in the filter box 27. The two first motors 21 drive the two first gears 22 to rotate synchronously and cooperate with the rack 23 to make the slide plate 2 slide along the slide groove 11, thereby bringing the filter box 27 to one side of the bearing box 3, so that the staff can take out the solids in the filter box 27 for processing.

[0034] Furthermore, such as Figure 3 As shown, an external gear 31 is rotatably mounted on the inner surface of the bearing box 3. Four second gears 32 are uniformly meshed on the inner surface of the external gear 31. The four second gears 32 mesh together with a third gear 33. A fifth motor 331 is fixedly connected to the bottom of the third gear 33. The fifth motor 331 is fixedly mounted on the bottom of the bearing box 3.

[0035] Four scrapers 311 are evenly fixedly installed on the top of the external gear 31, baffles 321 are fixedly installed on the top of the four second gears 32, a stirring plate 35 is fixedly installed on the top of the third gear 33, a support block 34 is fixedly installed on the inner wall of the bearing box 3, and the filter box 27 is movably installed on the top of the four support blocks 34.

[0036] In use, the filter box 27 is positioned on top of four support blocks 34. The output shaft of the fifth motor 331 drives the third gear 33 to rotate, which in turn drives the four second gears 32 to rotate. The four second gears 32 work together to rotate the external gear 31. When the external gear 31 rotates, it drives the four scrapers 311 to rotate. The scrapers 311 can clean the inner wall of the support box 3 and promote the flow of waste liquid in the inner cavity of the support box 3. The second gears 32 can drive the baffle 321 to rotate, and the third gear 33 can drive the stirring plate 35 to rotate. The function of the baffle 321 and the stirring plate 35 is to promote the flow of waste liquid in the inner cavity of the support box 3, so that the filter box 27 can filter the solids in the waste liquid.

[0037] Furthermore, such as Figures 4 to 6 As shown, a third motor 43 is fixedly installed on the outer surface of the connecting pipe 4. The output shaft of the third motor 43 passes through the inner cavity of the processing box 42 and is fixedly connected to a stirring blade 431. A first valve 451 is fixedly installed on the outer surface of the first downpipe 45. A waste liquid detector 47 is fixedly installed on the top of the second downpipe 46.

[0038] A third downpipe 48 is fixedly connected to one end of the second downpipe 46. Two second valves 481 are fixedly installed on the outer surface of the third downpipe 48, and the two second valves 481 are located on both sides of the second downpipe 46 respectively.

[0039] The third downpipe 48 is fixedly connected to a fourth downpipe 483 at one end. A second water pump 482 is fixedly installed on the outer surface of the fourth downpipe 483. One end of the fourth downpipe 483 is fixedly installed on the top of the carrier box 3.

[0040] When this utility model is in use, the waste liquid in the carrier tank 3 is first drawn into the treatment tank 42 by the first water pump 41. Then, the medicine is delivered into the treatment tank 42 by the medicine storage tank 44 to promote the coagulation of impurities in the waste liquid. The output shaft of the third motor 43 drives the stirring blade 431 to rotate, which can promote the mixing of medicine and waste liquid and accelerate the solid coagulation speed.

[0041] During discharge, the treated waste liquid flows out through the second downpipe 46 and is detected by the waste liquid detector 47. Waste liquid that passes the test and waste liquid that fails the test are discharged in different directions through two second valves 481. The qualified waste liquid is discharged directly, while the unqualified waste liquid is discharged again into the carrier tank 3 through the second water pump 482 and the fourth downpipe 483, so that the waste liquid can be re-treated by the treatment tank 42.

[0042] Working principle: First, the filter box 27 is placed inside the bearing box 3, and the four support blocks 34 support the filter box 27 together. Then, waste liquid is transported into the filter box 27. The output shaft of the fifth motor 331 drives the third gear 33 to rotate. The second gear 32 and the external gear 31 are driven by the third gear 33, which in turn causes the scraper 311, the baffle 321 and the stirring plate 35 to rotate, disturbing the waste liquid and promoting the separation of waste liquid and solids in the filter box 27. Finally, the output shaft of the second motor 24 drives the winding reel 25 to rotate, and with the connecting line 26, the filter box 27 can be lifted. Then, with the first gear 22 meshing with the rack 23, the lateral position of the filter box 27 can be moved, which makes it easier for the staff to clean the solids in the filter box 27.

[0043] Waste liquid in carrier tank 3 is drawn into treatment tank 42 by first water pump 41. Chemical agent is delivered into treatment tank 42 through chemical storage tank 44 to precipitate impurities in waste liquid. After treatment, first valve 451 is opened and waste liquid and impurities flow out through first downpipe 45. Waste liquid is separated from impurities by the action of strainer 457. Impurities flow out through the top of protrusion 456. Protrusion 456 can prevent impurities from flowing back. During use, the output shaft of fourth motor 453 drives waste plate 454 to rotate, which can promote the flow of impurities from first downpipe 45. Waste liquid enters second downpipe 46 and is detected by waste liquid detector 47. Qualified waste liquid is discharged with one of the second valves 481. Qualified waste liquid is discharged back into carrier tank 3 through second water pump 482 and fourth downpipe 483. Then, it is re-treated by treatment tank 42.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
