[0038] Further, the lifting mechanism includes two groups of guide wheels 34, the guide wheels 34 are in contact with the traction rope 35, the bottom ends of the front and rear sides of the traction rope 35 are respectively fixedly connected to the top of the bottom plate 25 and the capstan 36, the capstan 36 is provided with two groups, a connecting rod 37 is fixedly connected between the two groups of the capstan 36, two groups of support rings 38 are sleeved on the connecting rod 37, the inner wall of the support ring 38 is fixedly connected with a rubber ring 39, the rubber ring 39 is in contact with the connecting rod 37, one side of the capstan 36 is rotatably connected to the mounting frame 42, the support ring 38 and the mounting frame 42 are both fixedly connected to the rear end of the processing box 1, the left side of the capstan 36 is fixedly connected to the handle 41, the guide wheel 34 is rotatably connected to the retaining frame 33, and the bottom end of the retaining frame 33 is fixedly connected to the top of the support plate 73;

[0039] Through the structural design of the lifting mechanism, the function of lifting the two groups of bottom plates 25 inside the treatment box 1 upward is realized, so that the operator can clean the sludge collected on the bottom plates 25 more conveniently, and the cleaning effect can be further improved. During operation, the wastewater is first discharged into the first treatment area 22 through the pipe. The partition 24 is provided with a first through hole 44 and a second through hole 45. The first through hole 44 is in a closed state, and the second through hole 45 is in a connected state. Therefore, the wastewater inside the first treatment area 22 can flow to the second treatment area 23 through the second through hole 45. The sludge in the wastewater will also settle to the bottom of the first treatment area 22 and the second treatment area 23, and be collected through the bottom plate 25. When the sludge on the bottom plate 25 is to be processed, the handle 41 is turned to drive the winch 36 to rotate, and the middle of the two groups of winches 36 The two sets of winches 36 are connected together by a connecting rod 37, so that they can rotate synchronously. During the rotation of the winch 36, the traction rope 35 will be wrapped around the winch 36, and the base plate 25 fixed to the traction rope 35 will be pulled upward, so that the base plate 25 can be lifted upward from the bottom ends of the first treatment area 22 and the second treatment area 23 to a position aligned with the sewage trough 74, so that the operator can clean the sludge on the base plate 25. Two sets of support rings 38 are provided on the connecting rod 37. The support ring 38 is used to support the connecting rod 37 to ensure the stable rotation of the connecting rod 37. At the same time, a rubber ring 39 is fixed on the inner wall of the support ring 38. The rubber ring 39 maintains contact with the connecting rod 37 to provide resistance when the connecting rod 37 rotates, thereby ensuring that the winch 36 can remain stable and not rotate when it is not rotated by external force.

[0040] Furthermore, the bottom ends of the first treatment area 22 and the second treatment area 23 are both fixedly connected with four groups of aeration pipes 29, and the outer sides of the aeration pipes 29 are sleeved with fixing columns 28, and the fixing columns 28 are fixedly connected to the top ends of the inclined plates 27, and the inclined plates 27 are fixedly connected to the top ends of the bottom plates 25, and the bottom ends of the bottom plates 25 are penetrated by the aeration pipes 29;

[0041] During operation, an inclined plate 27 is fixed on the top of the bottom plate 25. The design of the inclined plate 27 allows sludge to accumulate near the front end of the bottom plate 25, and provides a certain slope when scraping the sludge so that the sludge can be scraped off smoothly. Four groups of fixed columns 28 are fixed on the inclined plate 27. The fixed columns 28 are sleeved on the outside of the aeration pipe 29. When the bottom plate 25 is lifted upward, the sliding of the fixed columns 28 on the aeration pipe 29 can play a guiding role, so that the bottom plate 25 can move upward stably.

[0042] Further, the opening and closing mechanism includes a gear 40, which is sleeved on the middle part of the connecting rod 37, and the top and bottom ends of the gear 40 are meshed with the long rod 50, and the side of the long rod 50 away from the gear 40 is fixedly connected with a convex plate 52, and the convex plate 52 is fixedly connected with a support spring 51, and the front end of the support spring 51 is fixedly connected with the processing box 1, and the two groups of the long rods 50 are respectively fixedly connected with the first stopper 47 and the second stopper 48 on the side away from the support spring 51, and the first stopper 47 and the second stopper 48 are slidably connected to the inside of the two groups of cavities 46, and the cavities 46 are opened inside the partition 24, and the two groups of the cavities 46 are respectively opened with a first through hole 44 and a second through hole 45, and the left and right sides of the first through hole 44 and the second through hole 45 are fixedly connected with a filter screen 43;

[0043] Through the structural design of the opening and closing mechanism, since the wastewater will be stratified when being processed in the first treatment area 22 and the second treatment area 23, the first through hole 44 will be opened and the second through hole 45 will be closed during the upward lifting of the bottom plate 25, so that the upper clear liquid in the first treatment area 22 can flow into the second treatment area 23 through the first through hole 44 and finally be discharged through the second drain port 21, so as to ensure that the upper clear liquid in the first treatment area 22 and the second treatment area 23 can be discharged in time before the sludge is processed, so as to avoid the sludge on the bottom plate 25 from contaminating the upper clear liquid due to the lifting of the bottom plate 25. When working, when the handle 41 is turned, the gear 40 fixed in the middle of the connecting rod 37 will rotate synchronously. And drive the two groups of long rods 50 engaged with it to move in the opposite direction. Since the long rods 50 are only partially engaged with the gears 40 and support springs 51 are also provided on the long rods 50, when the two groups of long rods 50 move in the opposite direction, the support springs 51 at the top ends will be stretched and the support springs 51 at the bottom ends will be compressed. The support springs 51 can ensure that the two groups of long rods 50 can always maintain contact with the gears 40. The reverse movement of the long rods 50 will push the first stopper 47 and the second stopper 48 to slide inside the cavity 46. The second through hole 45 that was originally connected will be blocked by the second stopper 48 and thus closed, and the first through hole 44 blocked by the first stopper 47 will be normally connected at this time, so that the liquid inside the first processing area 22 can flow to the second processing area 23.

[0044] Further, the scraping mechanism includes two sets of side plates 62, the side plates 62 are fixedly connected to the top of the support plate 73, the inside of the side plates 62 is provided with an inclined groove 63, the inclined groove 63 is provided with a movable groove 64 near the rear end, the inner wall of the movable groove 64 is fixedly connected with a connecting spring 65, the bottom end of the connecting spring 65 is fixedly connected to the connecting block 67, the connecting block 67 is provided with a notch 66, the top of the connecting block 67 is in contact with a sliding block 68, the sliding block 68 is slidably connected to the inside of the inclined groove 63, the sliding block 68 is rotatably connected to the knife holder 56, and the knife holder 56 is A scraper 55 is fixedly connected to the bottom end, and a connecting column 60 is fixedly connected to the side of the blade holder 56 away from the side plate 62. The connecting column 60 is rotatably connected to the moving wheel 57, and the moving wheel 57 is slidably connected to the inside of the through slot 54. The through slot 54 is opened inside the partition 24, and the through slot 54 passes through the partition 24. A pull rope 59 is fixedly connected to the front end of the connecting column 60, and the bottom end of the pull rope 59 is fixedly connected to a counterweight block 69. A gasket 70 is fixedly connected to the bottom end of the counterweight block 69, and the counterweight block 69 is slidably connected to the inside of a long slot 72, and the long slot 72 is opened inside the partition 24.

[0045] Through the structural design of the scraping mechanism, when the bottom plate 25 is lifted upward to the maximum height, the fixation of one side of the scraper 55 will be released, and the scraper 55 will move along the inclined surface of the inclined plate 27 under the pull of the pull rope 59, thereby scraping off most of the silt attached to the inclined plate 27, so as to reduce the subsequent cleaning difficulty of the operator and make the cleaning operation more convenient. During operation, when the bottom plate 25 is lifted upward to the maximum height, the bottom plate 25 will push the top of the connecting block 67 upward, and the connecting spring 65 fixed on the top of the connecting block 67 will be compressed. At this time, the notch 66 on the connecting block 67 will be aligned with the sliding block 68, and the sliding block 68 can pass through the notch 66 and slide in the inclined groove 63. The inclination angle of the inclined groove 63 is the same as that of the inclined groove 63. The plates 27 remain consistent. When the sliding block 68 is no longer blocked by the connecting block 67, the counterweight block 69 will fall downward under the action of gravity, thereby pulling the pull rope 59. The pull rope 59 will pull the connecting column 60 to slide in the through groove 54. The tool holder 56 will also slide forward along the through groove 54 and the inclined groove 63 at this time. The scraper 55 fixed at the bottom end of the tool holder 56 can scrape off the silt accumulated on the inclined plate 27. The moving wheel 57 is located between the two groups of connecting columns 60 to connect the two groups of connecting columns 60 to ensure that the connecting columns 60 can slide synchronously, the through groove 54 and the side plate 62 remain horizontal, and a gasket 70 is fixed on the bottom end of the counterweight block 69. The gasket 70 is made of rubber material and is used to directly buffer the bottom end of the counterweight block 69 and the inner wall of the long groove 72.

[0047] During operation, in order to prevent the tool holder 56 from rotating during the scraping process of the scraper 55, a limiting block 61 is fixedly connected to the bottom end of the connecting column 60. The limiting block 61 contacts the limiting groove 58, and the rotation of the tool holder 56 is restricted by the sliding of the limiting block 61 in the limiting groove 58, ensuring that the tool holder 56 does not rotate, thereby guaranteeing the scraping effect of the scraper 55.

[0048] Further, two sets of rectangular grooves 71 are formed in the scraper 55. The size of the rectangular grooves 71 is larger than that of the mounting block 30. The mounting block 30 is fixedly connected to the top end of the aeration pipe 29, and the mounting block 30 is designed in a T shape.

[0049] During operation, the rectangular grooves 71 are formed in the scraper 55 to prevent the scraper 55 from abutting against the mounting block 30. The mounting block 30 is designed in a T shape to facilitate restricting the maximum height to which the bottom plate 25 can move upward.

[0050] Further, two sets of connecting frames 31 are fixedly connected to the bottom plate 25. The connecting frames 31 are designed in a U shape. The connecting frames 31 contact the side wall of the partition plate 24. An insertion post 26 is fixedly connected to the front connecting frame 31, and the insertion post 26 is inserted inside a jack 53, and the jack 53 is formed inside the partition plate 24.

[0051] During operation, the two bottom plates 25 are connected together by the two sets of connecting frames 31 to facilitate improving the stability of the bottom plate 25 during movement. Moreover, the insertion post 26 is fixed to the front connecting frame 31 and is inserted inside the jack 53. By the contact between the insertion post 26 and the inner wall of the jack 53, the smoothness of the connecting frame 31 during movement can be further ensured.

[0053] Please refer to Figure 4 As shown, as another implementation manner of the present invention compared with Embodiment One, a fixing ring 32 is fixedly connected to the cage 33, and the fixing ring 32 is sleeved on the towing rope 35.

[0054] During operation, the fixing ring 32 is fixed to the cage 33 and sleeved on the towing rope 35. When the towing rope 35 is wound onto the winch 36, since there will inevitably be silt and debris attached to the part of the towing rope 35 immersed in the first treatment area 22 and the second treatment area 23, the fixing ring 32 can scrape it off, thereby ensuring the cleanliness of the towing rope 35.

[0055] A method for treating wastewater, the method comprising the following steps:

[0056] S1. Inject wastewater into the first treatment area 22. The wastewater in the first treatment area 22 will flow to the second treatment area 23 through the second through hole 45, so that the aeration pipe 29 is in working state, and ensure that the first drain port 20 and the second drain port 21 are in a closed state;

[0057] S2. When the handle 41 is turned, the first through hole 44 is opened, the second through hole 45 is closed, and the second drain port 21 is opened. The supernatant liquid in the first treatment area 22 flows to the second treatment area 23, and is finally discharged from the second drain port 21 together with the supernatant liquid in the second treatment area 23.

[0058] S3.
