Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 In this embodiment of the utility model, a wastewater recycling device for polyvinyl chloride production includes a treatment tank 10, a top tank 20, and a grid body 30. The top tank 20 is fixedly connected to four corners with connecting frames, which are bolted to the top of the treatment tank 10. The grid body 30 is installed on the bottom outer wall of the top tank 20. The grid body 30 consists of a main frame and multiple intercepting plates. The main frame is attached to the inner wall of the treatment tank 10 on three sides. The intercepting plates are linearly arranged on the inner wall of the main frame. A gap is left between two adjacent intercepting plates to allow wastewater to pass through. Large impurities in the wastewater are blocked by the intercepting plates, thus filtering the wastewater. A base plate structure is slidably connected inside the grille body 30. The base plate structure includes a connecting rod 60, a first connecting plate 61, and a second connecting plate 62. The connecting rod 60 is slidably connected in the gap between two adjacent intercepting plates on the grille body 30. The first connecting plate 61 and the second connecting plate 62 are respectively installed at both ends of the connecting rod 60. A cleaning component for cleaning dirt attached inside the grille body 30 is installed inside the connecting rod 60. A collection component for handling impurities is installed on the top of the second connecting plate 62. A lifting assembly for moving the first connecting plate 61 is installed on one side of the top box 20, and a discharge assembly for conveying impurities is installed on the top of the top box 20. The lifting assembly drives the connecting rod 60, the first connecting plate 61 and the second connecting plate 62 to move. The cleaning assembly rises with the connecting rod 60 to clean the impurities attached to the screen body 30, keeping the screen body 30 unobstructed and preventing it from clogging and affecting the passage of sewage. The second connecting plate 62 drives the top collection assembly to rise and store the impurities at the bottom into the collection assembly. After the collection assembly rises to the top, it sends the collected impurities into the top box 20, and the discharge assembly in the top box 20 sends the impurities out.

[0027] See Figure 8 and Figure 9The collection assembly includes a collection box 40. Mounting blocks 41 are fixedly connected to both ends of the top of the second connecting plate 62. A fixing rod 42 is fixedly connected between the two mounting blocks 41. Multiple rotating blocks 43 arranged linearly are installed at the bottom of the collection box 40. The rotating blocks 43 are rotatably connected to the outer wall of the fixing rod 42. Multiple filter holes arranged in a matrix are opened at the bottom of the collection box 40. The side of the collection box 40 near the grid body 30 is inclined. A guide plate 46 is installed at the bottom of the collection box 40. The guide plate 46 is inclined away from the grid body 30. When the collection box 40 moves upward with the second connecting plate 62, the collection box 40 can collect the impurities at the top. The water in the impurities can be discharged through the filter holes at the bottom of the collection box 40 and guided by the guide plate 46 to flow out away from the grid body 30.

[0028] Pins 45 are fixedly connected to both outer walls of the collection box 40. Electric push rods 44 are installed at both ends of the top of the second connecting plate 62. The electric push rods 44 are rotatably connected to the outer wall of the pins 45. When the collection box 40 moves to the top, the electric push rods 44 are activated. The electric push rods 44 retract and drive the collection box 40 to rotate on the outer wall of the fixed rod 42 via the rotating block 43. The collection box 40 can then turn to the side closer to the top box 20, and the impurities collected in the collection box 40 are poured into the top box 20.

[0029] See Figure 4 - Figure 6 The cleaning assembly includes a cleaning plate 72 and a cutting block 73. A partition is provided between the connecting rods 60, and a cleaning block 70 is installed between the connecting rods 60 on both sides. The cleaning plate 72 is installed on the outer walls of both sides of the cleaning block 70, and the cutting block 73 is installed at both ends of the top of the cleaning block 70. The cutting block 73 consists of a base plate and blades arranged linearly on the base plate. When the connecting rods 60 move, the cleaning block 70 between the connecting rods 60 moves synchronously with the connecting rods 60. The movement of the cleaning block 70 drives the cleaning plate 72 and the cutting block 73 to move. The cleaning plate 72 can clean the gaps between the grid bodies 30, and the cutting block 73 can cut the impurities wrapped between the grid bodies 30 with its blades, thus cleaning the impurities blocking the grid bodies 30.

[0030] A pressure block 71 is installed on the top of the cleaning block 70. A movable plate 74 is slidably connected to the inner wall of the cleaning block 70. A spring 75 is fixedly connected between the movable plate 74 and the inner wall of the cleaning block 70. A first connecting rod is fixedly connected to the middle of the top of the movable plate 74. The pressure block 71 is installed in the middle of the top of the movable plate 74 through the first connecting rod. Second connecting rods are installed at both ends of the top of the movable plate 74. A cutting block 73 is installed at both ends of the top of the movable plate 74 through the second connecting rod. Third connecting rods are installed on both sides of the movable plate 74. A cleaning plate 72 is installed on both sides of the movable plate 74 through the third connecting rod. When the cleaning block 70 moves upward, water can impact the pressure block 71. The pressure block 71, under impact, drives the moving plate 74 downward through the first connecting rod. The spring 75 at the bottom is compressed, and under the action of elastic force, the spring 75 drives the moving plate 74 upward. Then, the moving plate 74 moves back and forth in the vertical direction. The movement of the moving plate 74 can drive the cleaning plate 72 and the cutting block 73 to move back and forth through the second and third connecting rods. The cleaning plate 72 and the cutting block 73 can improve the cleaning effect between the grid bodies 30 through the stress of the back and forth movement.

[0031] See Figure 3 and Figure 7 The lifting assembly includes a sliding seat 51 and a telescopic rod 52. A side plate 24 is fixedly connected to one side of the outer wall of the top box 20. A servo motor 50 is fixedly connected to the top of the side plate 24. The telescopic rod 52 is fixedly connected to both ends of the bottom of the side plate 24. The other end of the telescopic rod 52 is fixedly connected to the top outer wall of the first connecting plate 61. The sliding seat 51 is fixedly connected to the middle position of the bottom of the side plate 24. An adjusting rod 54 is slidably connected inside the sliding seat 51. The bottom end of the adjusting rod 54 is fixedly connected to the middle position of the top of the first connecting plate 61. When the adjusting rod 54 slides inside the sliding seat 51, the first connecting plate 61 can move with the adjusting rod 54. At this time, the telescopic rod 52 can move and extend with the first connecting plate 61, thereby driving the first connecting plate 61, the docking rod 60, and the second connecting plate 62 to move.

[0032] A rectangular groove is provided on the inner wall of the sliding seat 51. A sliding block 55 is slidably connected to the inner wall of the rectangular groove. The sliding block 55 is fixedly connected to the top of the adjusting rod 54. A threaded hole is provided on the inner wall of the sliding block 55. A lead screw 53 is installed at the output end of the servo motor 50. The lead screw 53 is threadedly connected to the inner wall of the threaded hole on the sliding block 55. When it is necessary to move the adjusting rod 54, the servo motor 50 is turned on. The servo motor 50 starts and drives the lead screw 53 to rotate. The rotation of the lead screw 53 drives the threaded sliding block 55 to slide in the sliding seat 51. The movement of the sliding block 55 can drive the adjusting rod 54 to move synchronously.

[0033] See Figure 2The impurity removal assembly includes an auger 21 and a discharge pipe 22. A collection trough is provided on the inner wall of the top box 20. The auger 21 is installed on the inner wall of the collection trough. A baffle plate 23 for blocking impurities is installed on one side of the top box 20. The discharge pipe 22 is connected to the inner wall of the collection trough. When impurities enter the collection trough, the auger 21 is turned on, and the auger 21 can guide the impurities into the discharge pipe 22 and discharge them from the discharge pipe 22 for treatment.

[0034] The working principle of this utility model is as follows: When it is necessary to clean impurities, the servo motor 50 is turned on. The servo motor 50 starts and drives the threaded sliding block 55 to slide in the sliding seat 51 through the lead screw 53. This drives the first connecting plate 61, the docking rod 60 and the second connecting plate 62 to move upward through the adjusting rod 54. The upward movement of the second connecting plate 62 can drive the collection box 40 to move upward. The collection box 40 collects the impurities at the top inside. When the collection box 40 moves to the top, the electric push rod 44 is turned on. The electric push rod 44 retracts and drives the collection box 40 to rotate on the fixed rod 42 through the rotating block 43. The collection box 40 can then turn to the side closer to the top box 20 and pour the impurities inside into the collection groove on the top box 20. Then the auger 21 is started. The auger 21 guides the impurities to the discharge pipe 22 for discharge, thus processing the impurities at the grid body 30. When the connecting rod 60 moves upward, the cleaning block 70 moves upward synchronously with the connecting rod 60. The cleaning plate 72 and the cutting block 73 move with the cleaning block 70. The cleaning plate 72 wipes and cleans the gaps between the grid bodies 30, and the cutting block 73 cuts the impurities wrapped between the grid bodies 30 and cleans the impurities blocking the grid bodies 30. When the pressure block 71 moves with the cleaning block 70, it is impacted by the water, which drives the bottom moving plate 74 to move and compress the spring 75. Then, under the elastic force of the spring 75, the moving plate 74 can be driven to move in the opposite direction. The moving plate 74 moves back and forth in the vertical direction under the impact of the water flow and the elastic force of the spring 75, thereby driving the cleaning plate 72 and the cutting block 73 to move back and forth. The back and forth wiping of the cleaning plate 72 and the back and forth cutting of the cutting block 73 can improve the cleaning effect of impurities.

[0035] When in use, this utility model, through the set collection component, impurity discharge component and cleaning component, can clean and collect the impurities isolated under the screen body 30 and the impurities blocked in the screen body 30, and discharge them through the top auger 21 and discharge pipe 22, so as to avoid impurities blocking the screen body 30, affecting the flow of water, and thus affecting the efficiency of sewage treatment.

[0036] With the collection components in place, the cleaning plate 72 and the cutting block 73 can reciprocate the moving plate 74. The cleaning plate 72 wipes back and forth and the cutting block 73 cuts the impurities back and forth. The reciprocating movement can improve the cleaning effect of impurities in the grid body 30.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
