Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically a device for improving the recovery rate of a magnetic separator in a magnetic coagulation process. Background Technology
[0002] Magnetic coagulation, as a highly efficient wastewater treatment technology, is widely used in the current wastewater treatment field. Its core principle is to add a magnetic seed with a high specific gravity to the wastewater. The magnetic seed works synergistically with coagulants and coagulant aids. The coagulant first causes suspended solids and pollutants in the wastewater to form tiny flocs. The magnetic seed then combines with the flocs through adsorption and encapsulation to form "magnetic flocs" with strong magnetism and good settling properties. Due to the high specific gravity of the magnetic seed, the settling speed of the flocs is greatly accelerated, achieving rapid sedimentation separation and purification of wastewater.
[0003] In the complete process of magnetic coagulation, the magnetic separator plays a crucial role in "magnetic seed circulation." It can accurately separate the magnetic seeds from the flocs in the treated sludge, preventing the magnetic seeds from being lost with the sludge. The separated magnetic seeds can be returned to the front-end reaction system to continue participating in the coagulation reaction. This reduces the consumption cost of magnetic seeds and ensures the continuous and efficient operation of the entire process. It is the core equipment for achieving the economy and treatment efficiency of magnetic coagulation technology.
[0004] Currently, in actual operation, some magnetic powder particles are difficult to capture effectively due to their own characteristics, such as small size and weak magnetism. As a result, these magnetic powder particles are lost with wastewater or sludge, leading to a low recovery rate.
[0005] Therefore, a device for improving the recovery rate of the magnetic separator in the magnetic coagulation process is proposed to address the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.
[0019] Specific implementation examples are given below.
[0020] like Figures 1 to 5 As shown in the embodiment of this utility model, a device for improving the recovery rate of a magnetic separator in a magnetic coagulation process includes a housing 1, with a feed inlet 101 on the surface of the housing 1; a motor 102 fixedly connected to the side wall of the housing 1; a rotating rotor 103 fixedly connected to the output end of the motor 102; a magnetic attraction assembly 104 fixedly connected to the inner wall of the housing 1; a flexible shell 105 fixedly connected to the bottom of the housing 1; the bottom of the flexible shell 105 slidingly connected to the housing 1; and a sludge outlet 108 at the bottom of the housing 1. A horizontal plate 106 is fixedly connected to the bottom side wall; a spring telescopic rod 107 is fixedly connected to the surface of the horizontal plate 106; multiple spring telescopic rods 107 are provided; the ends of the spring telescopic rods 107 are fixedly connected to the surface of the flexible shell 105; an elastic cloth 111 is fixedly connected between the flexible shell 105 and the machine housing 1; a scraper 109 is fixedly connected inside the machine housing 1; the scraper 109 is inclined and corresponds to the rotating rotor 103; a magnetic powder outlet 110 is opened on the side wall of the machine housing 1; during operation, the motor 10 is started. 2. The motor 102 drives the rotating rotor 103 to rotate within the housing 1. The magnetic powder-containing sludge is then poured into the feed inlet 101, flowing into the flow space formed by the flexible shell 105 and the rotating rotor 103. The magnetic powder sludge flows within this space. As the flow space narrows towards the tail end, the flow rate decreases, making it easier for the magnetic powder to be attracted to the surface of the rotating rotor 103 by the magnetic attraction component 104 within the rotor 103. Ultimately, the magnetic powder is... The scraper 109 removes the magnetic powder from the outlet 110, while the flexible shell 105 increases the flow space by squeezing the spring telescopic rod 107 according to the flow rate of the poured magnetic powder sludge, thereby increasing the processing flow of the magnetic separator and preventing overflow. The elastic cloth 111 expands and contracts with the size of the flow space. This significantly improves the recovery rate of the magnetic separator, reduces the amount of magnetic seed replenishment, and reduces the loss of magnetic powder with wastewater and sludge, reducing the risk of secondary pollution and improving the overall operating efficiency and stability of the magnetic coagulation process.
[0021] like Figures 4 to 5As shown, the magnetic suction component 104 includes a low-magnetic block 2; a medium-magnetic block 201; and a high-magnetic block 202. The low-magnetic block 2, medium-magnetic block 201, and high-magnetic block 202 are all fixedly connected. During operation, when magnetic sludge is poured into the feed inlet 101, it flows through the flow space and is first attracted by the surface magnetic powder by the low-magnetic block 2. Then, as it flows, the medium-magnetic block 201 attracts the shallow magnetic powder, and finally, the high-magnetic block 202 attracts the deep magnetic powder, thus achieving a more refined adsorption of the magnetic powder in the magnetic sludge. In this way, the low-magnetic block 2, medium-magnetic block 201, and high-magnetic block 202 more refinedly adsorb the magnetic powder contained in the magnetic sludge, reducing the waste of magnetic powder in the magnetic sludge.
[0022] like Figures 1 to 2 As shown, the bottom of the mud outlet 108 is provided with a mud collection box 3; the bottom of the magnetic powder outlet 110 is provided with a magnetic powder collection box 301. During operation, when discharging sludge and magnetic powder, the mud collection box 3 collects the discharged sludge, while the magnetic powder collection box 301 collects the discharged magnetic powder. Thus, the mud collection box 3 and the magnetic powder collection box 301 collect the sludge and magnetic powder, reducing the workload.
[0023] like Figures 1 to 4 As shown, the side wall of the housing 1 is provided with an air inlet pipe 4; the bottom of the air inlet pipe 4 is connected to an air inlet branch pipe 401; the air inlet branch pipe 401 is connected to a hook-shaped pipe 402; multiple hook-shaped pipes 402 are provided; the hook-shaped pipes 402 are correspondingly provided with the scraper 109; during operation, when the scraper 109 removes magnetic powder from the rotating rotor 103, the air inlet pipe 4 is connected to an air pump, and the air pump blows air through the air inlet pipe 4 and the air inlet branch pipe 401 and finally sprays it from the multiple hook-shaped pipes 402 onto the surface of the scraper 109, so as to avoid the magnetic powder from accumulating on the surface of the scraper 109 and causing blockage; thus, the hook-shaped pipes 402 blow the magnetic powder on the surface of the scraper 109, so that the magnetic powder will not block the magnetic powder outlet 110.
[0024] like Figures 1 to 3 The feed inlet 101 shown is provided with a hollow plate 5; a square plate 501 is slidably connected inside the hollow plate 5; a push rod 502 is fixedly connected to the inner wall of the square plate 501; the push rod 502 is in a sliding relationship with the housing 1 and the hollow plate 5; during operation, when magnetic powder sludge is poured into the feed inlet 101, the push rod 502 can be used to push the square plate 501 to control the flow rate of the magnetic powder sludge and avoid clogging of the flow space; thus, by pushing the square plate 501 through the hollow plate 5, the flow rate of the magnetic powder sludge poured into the feed inlet 101 is controlled, preventing clogging inside.
[0025] like Figures 1 to 2As shown, the bottom of the magnetic powder collection box 301 has a hole 6; a magnetic plate 601 is slidably connected inside the hole 6; during operation, when magnetic powder falls into the magnetic powder collection box 301 through the magnetic powder outlet 110, the magnetic plate 601 at the bottom of the magnetic powder collection box 301 will attract the magnetic powder and fix the magnetic powder in the magnetic powder collection box 301. When the magnetic powder in the magnetic powder collection box 301 is poured out, it can be cleaned by pulling the magnetic plate 601 out of the hole 6; thus, the magnetic plate 601 fixes the magnetic powder in the magnetic powder collection box 301.
[0026] Working principle: By starting the motor 102, the motor 102 drives the rotating rotor 103 to rotate inside the housing 1. Then, the sludge containing magnetic powder is poured into the feed inlet 101, where it flows into the flow space formed by the flexible shell 105 and the rotating rotor 103. The magnetic powder sludge flows within the flow space. The closer to the tail end of the flow space, the smaller the flow space becomes, resulting in a decrease in flow rate. This makes it easier for the magnetic powder to be attracted to the surface of the rotating rotor 103 by the magnetic attraction component 104 inside the rotating rotor 103 due to the reduced flow rate. Finally, the magnetic sludge is scraped off by scraper 109 and discharged from magnetic powder outlet 110. The flexible shell 105 expands the flow space by squeezing spring telescopic rod 107 according to the flow rate of the poured magnetic sludge, increasing the processing flow of the magnetic separator and preventing overflow. The elastic cloth 111 expands and contracts with the size of the flow space. When magnetic sludge is poured in through feed inlet 101, it flows through the flow space and is first adsorbed by the surface magnetic powder by low magnetic blocks 2. Then, as it flows, it is adsorbed by medium magnetic blocks 201 to adsorb the shallow magnetic powder. Finally, it is adsorbed by high magnetic blocks 201. The magnet block 202 adsorbs the magnetic powder deep within it, achieving a more refined adsorption of the magnetic powder in the magnetic sludge; when discharging sludge and magnetic powder, the sludge collection box 3 collects the discharged sludge, while the magnetic powder collection box 301 collects the discharged magnetic powder; when the scraper 109 removes the magnetic powder from the rotating rotor 103, the air inlet pipe 4 is connected to an air pump, which sprays air through the air inlet pipe 4 and the air inlet branch pipe 401, ultimately spraying it onto the surface of the scraper 109 from multiple hook-shaped pipes 402, preventing magnetic powder from accumulating on the surface of the scraper 109 and causing blockage; When magnetic powder sludge is poured into the feed inlet 101, the flow rate of the magnetic powder sludge can be controlled by pushing the counter plate 501 with the push rod 502 to avoid clogging of the flow space. When the magnetic powder falls into the magnetic powder collection box 301 through the magnetic powder outlet 110, the magnetic plate 601 at the bottom of the magnetic powder collection box 301 will attract the magnetic powder and fix the magnetic powder in the magnetic powder collection box 301. When the magnetic powder in the magnetic powder collection box 301 is poured out, it can be pulled out from the hole 6 by pulling the magnetic plate 601 to clean the magnetic powder in the magnetic powder collection box 301.
