Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, and particularly relates to a magnetic adsorption recovery device for deep phosphorus removal. BACKGROUND

[0002] Phosphorus-containing wastewater mainly comes from agricultural fertilizer loss, domestic sewage discharge, and industrial production processes such as food, chemical industry and detergent, in which phosphate is a key factor causing water eutrophication. When phosphorus-containing wastewater is discharged into lakes and rivers, it will cause explosive reproduction of algae, leading to dissolved oxygen depletion, black and smelly water, fish death and ecological system collapse, which seriously threatens drinking water safety and human health. Therefore, phosphorus removal and recovery of phosphorus-containing wastewater not only is an urgent need to curb water environmental deterioration and restore water ecological function, but also is an inevitable choice to meet increasingly stringent sewage discharge standards and ensure sustainable use of water resources.

[0003] At present, the methods for treating and recovering phosphorus in wastewater mainly include chemical precipitation, adsorption, membrane treatment, microbial method and electrochemical method, etc. The adsorption method has the advantages of simple preparation, environmental friendliness, low cost and reusability, and can be applied to various environmental conditions and is not easily affected by environmental conditions, and has good application prospect. However, the existing magnetic adsorption recovery device for deep phosphorus removal usually uses gravity sedimentation method to separate water and magnetic flocs adsorbed with phosphate, but when the wastewater has a certain flowability or after the sedimentation is completed, the magnetic flocs may be discharged outward with the water flow, resulting in poor recovery effect of the magnetic adsorption recovery device for deep phosphorus removal.

[0004] Based on the above situation, the present application provides a magnetic adsorption recovery device for deep phosphorus removal with good recovery effect. SUMMARY

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0036] Example 1

[0037] A magnetic adsorption and recovery device for deep phosphorus removal, such as Figures 1-7As shown, the system includes a frame 1, a first processing box 11, a magnetic suction assembly 12, a filter assembly 13, a second processing box 14, a drive motor 15, a transmission assembly 1501, a moving frame 16, a servo motor 17, a lead screw 18, a limiting frame 19, a liquid storage cylinder 110, a drip holder 111, an air cylinder 112, a connecting pipe 113, a weight block 114, and a push block 115. The first processing box 11 is fixed to the top of the frame 1. The magnetic suction assembly 12 is installed inside the first processing box 11. The suction assembly 12 includes a mounting base and magnetic rods longitudinally distributed front and rear and rotatably connected to the mounting base. A second processing box 14 is fixedly connected to the top of the first processing box 11. A filter assembly 13 is installed on the upper part of the second processing box 14. A drive motor 15 is fixedly connected to the right side of the first processing box 11. A transmission assembly 1501 is installed on the right side of the first processing box 11. The output end of the drive motor 15 is fixedly connected to the transmission assembly 1501. The transmission assembly 1501 is inserted into the magnetic rods in the magnetic suction assembly 12. A movable frame 16 is slidably connected inside the second processing box 14. Servo motors 17 are fixedly connected to both the left and right sides inside the second processing box 14. Lead screws 18 are rotatably connected to both the left and right sides inside the second processing box 14. The output end of the servo motor 17 is fixedly connected to the adjacent lead screw 18. The lead screw 18 is threadedly connected to the movable frame 16. Limiting frames 19 are fixedly connected to both the front and rear sides inside the second processing box 14. Liquid storage cylinders 110 are fixedly connected to the top left and right sides of the limiting frames 19. A dripping device is fixedly connected to the top of the limiting frames 19. The drip rack 111 is fixedly connected to and connected to the adjacent liquid storage cylinder 110. The limiting frame 19 has air cylinders 112 fixedly connected to both sides. The air cylinders 112 are fixedly connected to and connected to the adjacent liquid storage cylinders 110 by a connecting pipe 113. The piston rod of the air cylinder 112 is fixedly connected to the outside of a weight block 114. The moving frame 16 is pressed and engaged with the piston rod of the air cylinder 112. The upper part of the moving frame 16 is slidably connected to an axially distributed push block 115, which is in contact with the second processing box 14.

[0038] like Figure 4 As shown, the mounting base of the magnetic suction assembly 12 has V-shaped scrapers that are longitudinally distributed front and back fixed to the right side, and the V-shaped scrapers are in contact with the magnetic rod of the magnetic suction assembly 12.

[0039] like Figure 6 As shown, the top of the air cylinder 112 has an air intake hole with a built-in one-way valve, and the connecting pipe 113 has a one-way valve installed in the middle.

[0040] When workers need to perform deep phosphorus removal and recycling of phosphorus-containing wastewater, the wastewater can be injected into the second treatment tank 14. During this process, the filter assembly 13 can screen out solid impurities in the wastewater. When the wastewater comes into contact with and gradually mixes with the phosphorus removal agent, flocculant, and magnetic powder slurry already added to the second treatment tank 14, a chemical reaction occurs, and magnetic flocs with phosphate adsorbed are generated with magnetic powder as the core, thereby achieving phosphorus removal treatment of the wastewater. When the wastewater in the second treatment tank 14 reaches a certain volume, the drive motor 15 and servo motor 17 can be started. The servo motor 17 will first drive the lead screw 18 to rotate in the forward direction, thereby driving the moving frame 16 and push block 115 to move downward. At this time, the piston rod of the air cylinder 112 is no longer affected by the moving frame. The compression of frame 16 will cause it to move downwards under the gravity of weight block 114 and draw outside gas into air cylinder 112 through the suction port with built-in one-way valve. When push block 115 moves downwards with moving frame 16 and comes into contact with second treatment tank 14, it will be blocked and unable to move further downwards. At this time, if moving frame 16 continues to move downwards, it will slide relative to push block 115 and create a gap. The wastewater after phosphorus removal treatment will then pass through the gap and flow into first treatment tank 11 from the bottom of second treatment tank 14. During this period, drive motor 15 will drive the magnetic rods distributed longitudinally in front and behind magnetic suction assembly 12 to rotate through transmission assembly 1501. And because the wastewater after phosphorus removal treatment flowing into first treatment tank 11 from the bottom of second treatment tank 14 is all The wastewater flows through the longitudinally distributed magnetic rods, allowing the magnetic rods in the magnetic attraction assembly 12 to separate the magnetic flocs from the wastewater using magnetic force. This prevents some of the magnetic flocs from being discharged with the water flow. The continuous rotation of the magnetic rods not only ensures uniform adsorption and separation of the magnetic flocs but also allows the V-shaped scraper on the magnetic attraction assembly 12 to clean the magnetic flocs from the surface of the rods, thus enabling long-term use of the magnetic rods. Since the cleaned-off magnetic flocs accumulate in the recesses of the V-shaped scraper, the magnetic attraction assembly 12 needs to be cleaned or replaced after a considerable period of use. The wastewater separated from the magnetic flocs is discharged from the drain outlet at the lower front of the first treatment tank 11. After treating this portion of the phosphorus-containing wastewater... The servo motor 17 drives the lead screw 18 to rotate in the opposite direction, thereby moving the moving frame 16 and push block 115 upwards to reset and receive subsequent phosphorus-containing wastewater, thus achieving intermittent discharge of wastewater after phosphorus removal treatment. The upward reset of the moving frame 16 also contacts and squeezes the piston rod of the air cylinder 112, causing the piston rod and weight block 114 to move upwards and inject the gas from the air cylinder 112 into the storage tank 110 through the connecting pipe 113. The phosphorus removal agent, flocculant, and magnetic powder slurry stored in the storage tank 110 are then dripped into the second treatment tank 14 through the drip rack 111 for replenishment and subsequent use. This automatically replenishes the second treatment tank 14 with phosphorus removal agent, flocculant, and magnetic powder slurry, thus continuously treating the phosphorus-containing wastewater.After all phosphorus-containing wastewater has undergone phosphorus removal treatment, the drive motor 15 and servo motor 17 can be turned off.

[0041] Example 2

[0042] Based on Example 1, such as Figure 8 and Figure 9 As shown, it also includes a throttling mechanism, which is set in the first processing box 11. The throttling mechanism includes a rotating block 2, a transmission sprocket 21 and a first transmission belt 22. The two transmission sprockets 21 are respectively installed on the left and right sides of the first processing box 11. The rotating block 2 is installed between the left and right transmission sprockets 21 and longitudinally distributed in the front and rear. The first transmission belt 22 is sleeved between the right transmission sprocket 21 and the output end of the drive motor 15.

[0043] like Figure 8 and Figure 9 As shown, a square through slot is provided in the middle of the rotating block 2.

[0044] When the drive motor 15 drives the magnetic rod in the magnetic attraction component 12 to rotate continuously through the transmission component 1501, the drive motor 15 also drives multiple rotating blocks 2 distributed longitudinally in the front and rear directions to rotate together through the first transmission belt 22 and the transmission sprocket 21. Since the rotating blocks 2 are located in the channel between the first treatment box 11 and the second treatment box 14 and have square through slots, when the drive motor 15 drives the rotating blocks 2 to rotate, the wastewater at the bottom of the second treatment box 14 will intermittently flow into the first treatment box 11, thereby further throttling the discharged wastewater after phosphorus removal treatment. This allows the magnetic attraction component 12 to efficiently adsorb and separate the magnetic flocs in the wastewater and avoids poor adsorption and separation effect of the magnetic attraction component 12 due to excessive and rapid water flow.

[0045] like Figure 10 and Figure 11 As shown, it also includes a vibration mechanism, which is set in the second processing box 14. The vibration mechanism includes a rotating shaft 3, a second transmission belt 31, a cam 32 and an oscillating plate 33. The two rotating shafts 3 are respectively rotatably connected to the front and rear sides inside the second processing box 14. The second transmission belt 31 is sleeved between the rotating shaft 3 and the right-side transmission sprocket 21. The axially distributed cam 32 is fixed to the outside of the rotating shaft 3. The axially distributed oscillating plate 33 is fixed to the outside of the limiting frame 19. The cam 32 and the adjacent oscillating plate 33 are pressed together.

[0046] When the transmission sprocket 21 operates continuously under the action of the drive motor 15 and the first transmission belt 22, the transmission sprocket 21 will also drive the rotating shaft 3 and the cam 32 to rotate through the second transmission belt 31. The cam 32 will first contact and squeeze the vibrating plate 33 as it rotates, and the vibrating plate 33 will then deform. When the cam 32 rotates to the point of separating from the vibrating plate 33, the vibrating plate 33 will then return to its original shape under its own elasticity. This cycle can make the vibrating plate 33 deform and recover back and forth and cause vibration. The vibration of the vibrating plate 33 will then transmit the vibration to the wastewater and other substances in the second treatment tank 14. In this way, the added phosphorus removal agent, flocculant and magnetic powder slurry can be diffused to the surroundings and fully contacted with the wastewater by means of vibration, thereby accelerating the reaction rate of phosphorus removal reaction.

[0047] like Figure 2 and Figure 12 As shown, it also includes an obstruction mechanism, which is disposed in the first processing box 11. The obstruction mechanism includes a magnetic plate 4 and a cover plate 41. The magnetic plate 4 is snapped into the inside of the first processing box 11, and the cover plate 41 is installed on the rear side of the first processing box 11. The cover plate 41 is in contact with the magnetic plate 4.

[0048] like Figure 2 and Figure 12 As shown, the top of the magnetic plate 4 has grooves distributed longitudinally in the front and back.

[0049] When the wastewater after phosphorus removal flows from the second treatment tank 14 into the first treatment tank 11, the wastewater will first fall onto the magnetic plate 4 and then flow down the slope and finally be discharged outward from the drain outlet at the lower front side. During this process, the magnetic plate 4 will not only adsorb and separate the magnetic flocs in the wastewater after phosphorus removal through its own magnetism, but also use the longitudinally distributed grooves on its surface to hinder the movement of the magnetic flocs in the wastewater, making it easier for the magnetic flocs to be deposited in the grooves. This can effectively prevent the magnetic flocs from being discharged outward with the wastewater. When a large amount of magnetic flocs are deposited in the grooves, the cover plate 41 needs to be removed first, and then the magnetic plate 4 needs to be cleaned or replaced. The presence of the cover plate 41 can provide protection for the magnetic plate 4 and limit its movement.

[0050] like Figure 13 and Figure 14 As shown, it also includes a flow mechanism, which is set in the second processing tank 14. The flow mechanism includes a water pump 5, a guide pipe 51, a suction plate 52, a spray plate 53, and a liquid guide pipe 54. Two water pumps 5 are fixedly connected to the front and rear sides of the second processing tank 14 respectively. Suction plates 52 are fixedly connected to both the front and rear sides inside the second processing tank 14. The suction plates 52 are fixedly connected to the water pumps 5 and connected by two left and right guide pipes 51. The spray plate 53 is fixedly connected to the second processing tank 14. The spray plate 53 is fixedly connected to the water pumps 5 and connected by two left and right liquid guide pipes 54.

[0051] When treating phosphorus-containing wastewater, water pump 5 can be started. Water pump 5 will first suck up the wastewater from the inner edge of the second treatment tank 14 through the guide pipe 51 and suction plate 52, and then spray the sucked wastewater out of the middle of the second treatment tank 14 through the liquid guide pipe 54 and spray plate 53. This will increase the fluidity of the wastewater and make it circulate in the second treatment tank 14 and mix it thoroughly and evenly with the added phosphorus removal agent, flocculant and magnetic powder slurry, thereby achieving deep phosphorus removal of phosphorus-containing wastewater. When not needed, water pump 5 can be turned off.

[0052] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
