Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a superconducting magnetic coagulation device for sewage treatment. Background Art

[0002] Superconducting magnetic medium coagulation and sedimentation water treatment technology is a further extension and upgrade of magnetic medium coagulation and sedimentation technology. This technology forms superconducting magnetic medium by modifying ordinary magnetic medium, and replaces the "deflocculant + magnetic separator" in conventional magnetic medium coagulation and sedimentation technology with superconducting magnetic medium separator, thereby improving the adsorption efficiency of magnetic medium on pollutants in water.

[0003] During the treatment process, the superconducting magnetic coagulation equipment first carries out magnetic medium addition and coagulation reaction. During the coagulation process of water treatment, the equipment accurately adds superconducting magnetic medium and at the same time, adds coagulant to the wastewater to form preliminary flocs. Then the floc formation and sedimentation are accelerated. The preliminary formed flocs and magnetic powder attract and combine with each other. Then the flocculant is added. The flocculant acts as a bridge between the flocs, so that the small flocs further aggregate and grow to form larger and stronger magnetic flocs. Then the magnetic flocs quickly settle to the bottom of the sedimentation tank. Finally, the magnetic medium is recovered. The sludge at the bottom of the sedimentation tank is pumped to the magnetic powder recovery system through a reflux pump. The controllable, super-strong, high-gradient magnetic field generated by the superconducting magnet is used to efficiently separate the superconducting magnetic medium from the water or sludge and recycle it.

[0004] When the existing superconducting magnetic coagulation equipment is treating sewage, if the incoming sewage contains a large amount of grease, suspended matter or colloids, which exceeds the processing capacity of the superconducting magnetic coagulation equipment, the flocs formed by these substances are too fine and loose, and will form scum on the surface of the sedimentation tank. The formed scum will form a layer of covering on the surface of the sedimentation tank. Part of the scum flows out of the sedimentation tank with the water flow and enters the subsequent treatment unit, resulting in an increase in suspended matter in the effluent, deterioration of water quality, and affecting the sewage effect. The existing superconducting magnetic coagulation equipment cannot scrape and clean the scum well. For this reason, we propose a superconducting magnetic coagulation equipment for sewage treatment.

[0020] Example 1: Please refer to Figure 1 - Figure 7 A superconducting magnetic coagulation device for sewage treatment comprises a mixing tank 1, a magnetic powder mixing mechanism 2 installed inside the mixing tank 1, and a sedimentation tank 3 installed on one side of the mixing tank 1. A conducting pipe 4 is fixedly installed inside the mixing tank 1 and the side near the top of the sedimentation tank 3. A driving motor 5 is fixedly connected to the middle position of the top of the sedimentation tank 3 through a bracket. A sludge scraper 6 is coaxially fixed to the output end of the driving motor 5. A sewage scum treatment component is arranged on the side near the top of the sludge scraper 6; the sewage scum treatment component comprises a limit cover 8 and a transmission shaft 12. The limit cover 8 is laterally penetrated and slidably installed on the outside of one side of the sludge scraper 6, and the transmission shaft 12 is rotatably penetrated and installed on the inside of one side of the opening end of the limit cover 8. Two transmission shafts 12 are symmetrically arranged, and a floating adjustment component is arranged on the side of the limit cover 8 close to the sludge scraper 6, and a transmission component is arranged on the side of the limit cover 8 away from the sludge scraper 6. A slag removal component is arranged on the bottom end of one side of the limit cover 8.

[0021] The two transmission shafts 12 are externally sleeved with a transmission belt 13, which is tilted when viewed from the side, and the outer surface of the transmission belt 13 is fixedly connected with a plurality of upwardly tilted intercepting teeth 14 at equal intervals.

[0022] The floating adjustment assembly includes a stopper 10 and a floating plate 11. The stopper 10 is fixedly installed on the outside of one side of the sludge scraper rod 6 near the bottom end of the limit cover 8. The floating plate 11 is fixedly connected to the outside of one side of the bottom end of the limit cover 8. The sludge scraper rod 6 is near the outside of the limit cover 8 and is longitudinally fixed with a plurality of positioning strips 9 at equal angles. The limit cover 8 and the plurality of positioning strips 9 are connected by a through sliding connection.

[0023] The transmission assembly includes a contact wheel 18, which is rotatably installed on the outside of the top side of the limiting cover 8 close to the inner wall of the sedimentation tank 3. One side of the contact wheel 18 is in contact with one side of the inner wall of the sedimentation tank 3. An installation cavity 15 is provided inside the side of the limiting cover 8 close to the contact wheel 18. A worm 16 is longitudinally rotatably installed inside one side of the installation cavity 15. The top of the worm 16 is fixedly installed on one side of the contact wheel 18. A worm wheel 17 is meshingly connected to one side of the worm 16. One side of the worm wheel 17 is fixedly installed on one end of one of the transmission shafts 12.

[0024] The slag cleaning component includes a suction pipe 19 and a comb tooth block 20. The suction pipe 19 is fixedly installed inside the bottom end side of the limiting cover 8 away from the transmission shaft 12. The comb tooth block 20 is fixedly installed inside the bottom end side of the limiting cover 8 close to the transmission belt 13. One side of the comb tooth block 20 is in contact with the surface of one side of the transmission belt 13.

[0025] In the present embodiment, after the water treated by the magnetic powder mixing mechanism 2 enters the sedimentation tank 3 through the conducting pipe 4 and settles inside, when it is necessary to scrape the mud from the bottom of the sedimentation tank 3, the driving motor 5 at the top is started, and the output shaft of the driving motor 5 is rotated, thereby driving the sludge scraper rod 6 at the bottom to rotate. When the sludge scraper rod 6 rotates, it is connected by the sliding engagement of the limit cover 8 and the positioning strip 9, so that the rotation of the sludge scraper rod 6 will drive the limit cover 8 to rotate synchronously. When the limit cover 8 rotates on the water surface, it will drive the transmission belt 13 inclined at the side to scrape the scum on the water surface. At the same time, through the inclined setting of the transmission belt 13 and the plurality of intercepting teeth 14 inclined upward on the surface of the transmission belt 13, the scum can be better attached to the surface of the transmission belt 13 when being scraped by the transmission belt 13, so that the scum attached to the surface of the transmission belt 13 can be subsequently transported and cleaned, and the overall scum scraping effect is better.

[0026] It should be noted that when the limit cover 8 rotates to scrape the residue, the interference wheel 18 that is in contact with the inner wall of the sedimentation tank 3 on one side will rotate, thereby driving the worm 16 to rotate. Through the rotation of the worm 16, the worm wheel 17 that is meshed on one side is driven to rotate, thereby driving the transmission shaft 12 and the transmission belt 13 to rotate and transport, and the scum on the surface of the transmission belt 13 is transmitted. The comb block 20 that is in contact with one side of the transmission belt 13 is used to effectively scrape off the scum transmitted on the surface of the transmission belt 13, so as to scrape, collect and clean the scum on the water surface to ensure the overall cleaning effect. At the same time, when in use, the suction pipe 19 can also be connected to an existing external suction pump to suck and discharge the scraped scum.

[0027] It should be noted that when the liquid level inside the sedimentation tank 3 changes, through the setting of the floating plate 11 at the bottom of the limit cover 8 and the sliding connection between the limit cover 8 and the positioning bar 9, the overall position can be changed synchronously with the change of the liquid level, ensuring that the limit cover 8 can always be on the water surface, ensuring that the scum can be effectively scraped off, and ensuring the overall operational stability.

[0028] Example 2: Please refer to Figure 8 - Fig.11 In order to further illustrate the example in this embodiment, a reciprocating component and a liquid injection component are arranged on the outside of the sludge scraper rod 6 away from the limiting cover 8.

[0029] The reciprocating assembly includes a limit box 21 and a reciprocating screw 22. The limit box 21 is fixedly installed on the side of the limit cover 8 away from the inner wall of the sedimentation tank 3. The reciprocating screw 22 is longitudinally rotatably installed inside one side of the limit box 21. One end of one of the transmission shafts 12 is rotatably installed inside one side of the limit box 21. A bevel gear set 23 is installed for meshing transmission between the bottom end of the reciprocating screw 22 and the rotating through end of the transmission shaft 12.

[0030] A positioning rod 24 is longitudinally installed inside the side of the limit box 21 away from the reciprocating screw 22, and a limiting block 25 is arranged outside the positioning rod 24 and one side of the reciprocating screw 22. The limiting block 25 and the positioning rod 24 are connected by a through sliding connection, and the limiting block 25 and the reciprocating screw 22 are connected by a through thread.

[0031] The liquid injection assembly includes a liquid collecting cylinder 26 and a piston block 30. The liquid collecting cylinder 26 is longitudinally penetrated and fixedly installed inside one side of the limit block 25. The piston block 30 is slidingly sealed and installed inside one side of the bottom end of the liquid collecting cylinder 26. The bottom end of the piston block 30 is longitudinally fixedly connected with a resistance rod 31. A one-way valve 27 is penetrated and fixedly installed on the top end of the liquid collecting cylinder 26. A stretch hose 28 is connected and fixedly connected to the input end of the one-way valve 27. A fixing frame 7 is penetrated and fixedly installed on the outside of one side near the top of the sludge scraper rod 6. A liquid storage tank 29 is fixedly installed on one side of the top end of the fixing frame 7. The input bottom end of the stretch hose 28 is penetrated and fixedly installed inside one side of the bottom end of the liquid storage tank 29.

[0032] An inverted L-shaped discharge pipe 34 is fixedly installed on one side of the top of the liquid collecting cylinder 26, and the output end of the discharge pipe 34 is placed inside the sedimentation tank 3. A return spring 33 is sleeved on the outside of the resistance rod 31 located inside the liquid collecting cylinder 26. Both ends of the return spring 33 are respectively installed on one side of the piston block 30 and the liquid collecting cylinder 26, and a resistance block 32 is fixedly installed on the bottom end of the resistance rod 31.

[0033] A plurality of through holes 35 are arranged at equal angles around the inside of the resistance block 32, a limiting plate 36 is fixedly connected to the outside of the limit box 21 near the bottom end of the resistance rod 31, the inside of the limiting plate 36 is penetrated by the resistance rod 31, and a ejector pin 37 is fixedly installed on the outside of the limit plate 36 near the bottom end of the plurality of through holes 35, and the outer diameter of the ejector pin 37 is smaller than the inner diameter of the through hole 35.

[0034] In this embodiment, when the sludge scraper rod 6 drives the limit cover 8 to rotate to scrape off the scum, the transmission shaft 12 inside the limit cover 8 rotates, and cooperates with the meshing transmission connection of the bevel gear set 23 to drive the reciprocating screw 22 inside the limit box 21 on one side to rotate. At the same time, through the limitation of the positioning rod 24 on the other side, the limit block 25 drives the liquid collecting cylinder 26 on one side to move up and down. When the liquid collecting cylinder 26 descends, it will drive the piston block 30, the resistance rod 31 and the resistance block 32 inside the bottom end to descend synchronously. When the resistance block 32 descends, After a certain depth, it contacts the water surface. In the process of continuing to descend, due to the resistance pressure of the resistance block 32 contacting the water surface, the top piston block 30 and the resistance rod 31 are driven to move upward for a short distance, so that a certain amount of the previously extracted coagulant in the liquid collecting cylinder 26 is squeezed into the inside of the discharge pipe 34, and then injected into the sedimentation tank 3 through the discharge pipe 34. The injected polymer coagulant has a long chain structure and multiple active groups, so it can absorb fine particles in the water and connect them to form The larger flocs play a connecting role between the particles, so that the grease, suspended matter or colloid fine particles in the sewage form larger flocs, accelerate the sedimentation speed, and thus to a certain extent can reduce the generation of scum on the water surface of the sedimentation tank 3. When the reciprocating screw 22 rotates and drives the liquid collecting cylinder 26 to descend to a certain depth and start to move upward, when it moves to a certain position, the resistance block 32 is separated from the water surface, and the return spring 33 inside the liquid collecting cylinder 26 drives the piston block 30 and the resistance rod 31 to move back. When moving back, the one-way valve 27 and the guide of the stretch hose 28 are used to guide the piston block 30 and the resistance rod 31. The fluid collecting tube 26 is connected to the fluid storage tank 29, thereby extracting a certain amount of the coagulant previously injected into the fluid storage tank 29 into the fluid collecting tube 26 for subsequent use. According to the above steps, the limiting cover 8 drives the fluid collecting tube 26 to reciprocate multiple times during rotation, thereby injecting a certain amount of the coagulant into the sedimentation tank 3 evenly and surroundingly to ensure the overall use effect. At the same time, after the resistance block 32 is separated from the water surface and moves to a certain height, the through hole 35 inside it will be cleared by the ejector pin 37 on one side of the limiting disk 36 to avoid blockage of the through hole 35.

[0035] It should be noted that when there is a lot of thick scum on the water surface of the sedimentation tank 3, when the resistance block 32 descends close to the water surface, the excessive scum on the water surface will block several through holes 35 inside the resistance block 32, causing the resistance pressure of the resistance block 32 to increase when it descends close to the water surface. This pressure change can drive the top piston block 30 and the resistance rod 31 to move upward a larger distance, thereby increasing the amount of coagulant discharged, so that the overall amount of coagulant injected can be automatically increased according to the increase in the thickness of the scum, thereby ensuring the overall coagulant sedimentation effect.
