[0017] Example: See Figure 1 - Figure 5 The utility model provides a technical solution: a magnetic separator for sewage treatment, comprising: a base 1; a water inlet tank 2, the bottom of the outer wall of the water inlet tank 2 is fixedly connected to the inner wall of the base 1; a servo motor 3, the outer wall of the servo motor 3 is fixedly connected to the side wall of the base 1; a screening device 4, the outer wall of the screening device 4 is fixedly connected to the output end of the servo motor 3; a pushing device 5, the outer wall of the pushing device 5 is slidably connected to the inner wall of the water inlet tank 2; a screening box 6, the side wall of the screening box 6 is fixedly connected to both sides of the inner wall of the base 1; a water outlet pipe 7, the outer wall of the water outlet pipe 7 is fixedly connected to the screening box 6 The outer wall of the magnetic outlet pipe 8 is fixedly connected to the outer wall of the screening box 6, the outer wall of the screening box 6 is fixedly connected to the outer wall of the water inlet box 2, and the outer wall of the pushing device 5 is rotatably connected to the inner wall of the base 1. When the pretreated sewage enters through the upper inlet of the water inlet tank 2 and flows into the screening box 6, the servo motor 3 is started. Driven by the servo motor 3, the connecting shaft 41 is driven to rotate in the barrier tube 45, thereby driving the rotating tube 42 on the fixed tube 43 to rotate, and the rotation direction of the rotating tube 42 is opposite to the flow direction of the sewage flowing into the screening box 6.

[0018] The screening device 4 includes a connecting shaft 41, the outer wall of the connecting shaft 41 is fixedly connected to a rotating tube 42, the inner wall of the rotating tube 42 is rotatably connected to a fixed tube 43, the inner wall of the fixed tube 43 is fixedly connected to a magnetic block 44, the side of the magnetic block 44 away from the fixed tube 43 is fixedly connected to a barrier tube 45, the outer wall of the fixed tube 43 is rotatably connected to a rotating ring 46, the outer wall of the connecting shaft 41 is fixedly connected to the output end of the servo motor 3, the end of the rotating tube 42 away from the servo motor 3 is fixedly connected to the outer wall of the rotating ring 46, the outer wall of the fixed tube 43 and the outer wall of the barrier tube 45 are both fixedly connected to the side of the inner wall of the screening box 6 away from the servo motor 3, and the inner wall of the barrier tube 45 is rotatably connected to the inner wall of the connecting shaft 41 When the sewage approaches the bottom of the rotating tube 42, due to the magnetic attraction of the magnetic block 44 in the rotating tube 42, the coagulation block with magnetic powder is adsorbed on the rotating tube 42 and the rotating ring 46. Due to the rotation of the rotating tube 42, the coagulation block adheres to the rotating tube 42 and the rotating ring 46, and moves with the rotating tube 42 until the coagulation block moves out of the area where the magnetic block 44 is located. Due to the distance of the magnetic attraction area, the magnetic attraction fails and the gravity of the coagulation block causes the coagulation block to fall to the top entrance of the magnetic outlet pipe 8 and flow out of the magnetic outlet pipe 8. The sewage with the coagulation block removed passes through the screening box 6 and enters the outlet pipe 7 under the push of the sewage in the water inlet tank 2, completing the magnetic separation of the sewage.

[0019] The pushing device 5 includes a sliding plate 51, a movable rod 52 is fixedly connected to the bottom of the sliding plate 51, a rotating rod 53 is rotatably connected to the inner wall of the bottom of the sliding plate 51, an end of the rotating rod 53 away from the sliding plate 51 is rotatably connected to an eccentric disk 54, a rotating shaft 55 is fixedly connected to the center of the outer wall of the eccentric disk 54, a rotating handle 56 is fixedly connected to the outer wall of the rotating shaft 55, the outer wall of the rotating shaft 55 is rotatably connected to the inner wall of the base 1, the end of the movable rod 52 away from the sliding plate 51 is fixedly connected to the bottom of the inner wall of the water inlet tank 2, the outer wall of the rotating rod 53 is slidably connected to the inner wall of the bottom of the water inlet tank 2, the inner wall of the water inlet tank 2 is slidably connected to the side wall of the sliding plate 51, and the rotating shaft is fixedly connected to the inner wall of the bottom of the water inlet tank 2. Under the rotation of 55, the eccentric disk 54 rotates along with the rotation of the rotating shaft 55. Since the eccentric position of the eccentric disk 54 on the side away from the rotating shaft 55 is rotatably connected to the inner wall of the bottom of the rotating rod 53, the bottom of the rotating rod 53 will perform periodic movement under the rotation of the eccentric disk 54, and the movement of the rotating rod 53 will drive the sliding plate 51 connected to the top of the rotating rod 53 to move up and down. The sliding plate 51 moves up and down under the limitation of the water inlet tank 2 and the movable rod 52, so that the sewage entering the water inlet tank 2 is difficult to deposit at the bottom of the water inlet tank 2, thereby avoiding the accumulation of coagulants at the bottom of the water inlet tank 2. At the same time, the sliding plate 51 moving upward can assist the sewage to enter the screening box 6.

[0020] Working principle:

[0021] When in use, the screening device 4 performs magnetic powder screening on the sewage entering the magnetic separator. Since the magnetic coagulation technology is used during sewage treatment, the impurities in the sewage are condensed by the magnetic powder to form large lumps of coagulants. Therefore, the purpose of collecting magnetic powder is achieved by separating the condensate and water during the magnetic separation process. When the pre-treated sewage enters through the upper inlet of the water inlet tank 2 and flows into the screening box 6, the servo motor 3 is started. Driven by the servo motor 3, the connecting shaft 41 is driven to rotate in the barrier tube 45, thereby driving the rotating tube 42 on the fixed tube 43 to rotate, and the rotation direction of the rotating tube 42 is opposite to the flow direction of the sewage flowing into the screening box 6. When the sewage is close to the bottom of the rotating tube 42, due to the rotation The magnetic block 44 in the moving tube 42 has a magnetic attraction, which adsorbs the coagulation block with magnetic powder on the rotating tube 42 and the rotating ring 46. Due to the rotation of the rotating tube 42, the coagulation block adheres to the rotating tube 42 and the rotating ring 46, and moves with the rotating tube 42 until the coagulation block moves out of the area where the magnetic block 44 is located. Due to the distance of the magnetic attraction area, the magnetic attraction effect fails and the gravity of the coagulation block causes the coagulation block to fall to the top entrance of the magnetic outlet pipe 8 and flow out of the magnetic outlet pipe 8. The sewage with the coagulation block removed passes through the screening box 6 and enters the outlet pipe 7 under the push of the sewage in the water inlet tank 2, completing the magnetic separation of the sewage and reducing the number of times the magnetic separator is shut down for cleaning.

[0022] A pushing device 5 is provided to push the sewage into the water tank 2. When in use, the user drives the rotating shaft 55 to rotate by turning the rotating handle 56 exposed on the outer wall of the base 1. Under the rotation of the rotating shaft 55, the eccentric disk 54 rotates following the rotation of the rotating shaft 55. Since the eccentric position of the eccentric disk 54 away from the rotating shaft 55 is rotatably connected to the inner wall of the bottom of the rotating rod 53, under the rotation of the eccentric disk 54, the bottom of the rotating rod 53 will perform periodic movement, and the movement of the rotating rod 53 will drive the upper connection of the rotating rod 53 to rotate. The sliding plate 51 moves up and down. Since the two sides of the bottom of the sliding plate 51 are connected to the water inlet box 2 through the movable rod 52, and the side walls of the sliding plate 51 slide on the inner wall of the water inlet box 2, the sliding plate 51 moves up and down under the limit of the water inlet box 2 and the movable rod 52, so that the sewage entering the water inlet box 2 is difficult to settle at the bottom of the water inlet box 2, thereby avoiding the accumulation of coagulation blocks at the bottom of the water inlet box 2. At the same time, the sliding plate 51 moving upward can assist the sewage to enter the screening box 6, thereby reducing the frequency of cleaning of the water inlet box 2 by the staff and reducing the work intensity of the staff.
