Description

Technical Field

[0001] This invention relates to the field of steelmaking wastewater treatment technology, specifically to a pre-treatment steelmaking wastewater treatment device. Background Technology

[0002] Steelmaking wastewater treatment equipment is a complete treatment system specifically designed for the highly polluting wastewater generated during the steelmaking process in steel enterprises. It aims to remove pollutants from the wastewater through physical, chemical, and combined physical-chemical technologies, achieving water purification and recycling while meeting environmental emission standards. Its design must adapt to the complex characteristics of steelmaking wastewater, balancing efficient treatment with resource recovery. It is a core piece of equipment for energy conservation, emission reduction, and green production in the steel industry. Steel enterprises generate a large amount of wastewater during production, mainly including wastewater from ironmaking, steelmaking, and rolling mill workshops. From a usage perspective, it can be divided into indirect cooling wastewater and washing wastewater. This wastewater contains mud impurities, organic matter, salts, and may also contain ammonia nitrogen, phenols, heavy metals, and other substances. Its complex composition means that direct discharge would severely pollute the soil, water bodies, and other ecological environments, affecting the growth of surrounding plants and animals and human health.

[0003] With increasingly stringent environmental protection requirements, pretreatment, as the primary step, is crucial for improving overall wastewater treatment efficiency. However, some existing steelmaking wastewater treatment equipment suffers from insufficient mixing efficiency when using coagulation or flocculation methods. This results in incomplete mixing of the agent and wastewater, causing impurities to clump together and deposit on the walls, making cleaning difficult and impacting operational efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pre-treatment steelmaking wastewater treatment device, comprising:

[0005] The main body shell has water outlet pipes fixedly connected to both sides, a mixing component is rotatably connected to the inside of the main body shell, and an adsorption component is fixedly connected to the bottom of the mixing component.

[0006] The feeding component is used to add chemicals to steelmaking wastewater, and the bottom of the feeding component is fixedly connected to the top of the main body shell.

[0007] The feeding component includes a material storage shell, the bottom of which is fixedly connected to the top of the main shell, a driving component fixedly connected to the top of the material storage shell, a mesh plate fixedly connected to the bottom of the material storage shell, feeding pipes fixedly connected to both sides of the top of the material storage shell, water inlet pipes fixedly connected to both sides of the material storage shell, and a material storage mechanism rotatably connected to the middle of the inner cavity of the material storage shell.

[0008] An appropriate amount of reagent is added into the storage shell through the feed pipe. After entering through the feed pipe, the reagent is temporarily stored in the storage mechanism. At the same time, sewage is continuously fed into the inner cavity of the storage shell through the water inlet pipe. Then, the drive unit is activated, and the output end of the drive unit will drive the storage mechanism to move, adding a quantitative amount of reagent to the sewage entering the storage shell, completing the initial combination of reagent and sewage.

[0009] The material storage mechanism includes a rotating shaft and a baffle plate. The side of the rotating shaft is rotatably connected to the top of the inner cavity of the material storage shell. The top of the rotating shaft is fixedly connected to the output end of the drive component. The side of the rotating shaft is rotatably connected to the inner side of the first mesh plate. A connecting shaft is fixedly connected to the side of the rotating shaft. Sliding rods are slidably connected to both sides of the connecting shaft. A stop block is fixedly connected to the bottom of the sliding rod. The side of the stop block contacts the inner side of the baffle plate. A first spring is sleeved on the sliding rod. The top of the first spring is fixedly connected to the side of the connecting shaft. The bottom of the first spring is fixedly connected to the top of the stop block. The side of the baffle plate is fixedly connected to the middle of the inner cavity of the material storage shell. A spiral blade is fixedly connected to the side of the rotating shaft away from the connecting shaft. A cleaning brush is fixedly connected to the side of the rotating shaft. The side of the cleaning brush contacts the top of the first mesh plate.

[0010] When wastewater continuously enters the storage shell through the inlet pipe, the drive unit is activated, and its output end drives the rotating shaft to rotate. In turn, the rotating shaft drives the connecting shaft to rotate synchronously in the inner cavity of the storage shell. When the connecting shaft rotates, it drives the baffle to disengage from the baffle plate through the slide rod, causing the agent originally stored on the top of the baffle plate to fall into the wastewater, realizing the automatic mixing of the agent and wastewater. There is no need for manual addition of the agent, which improves the accuracy and efficiency of the dosing and reduces the cost of manual operation.

[0011] At the same time, the rotating shaft drives the spiral blades to rotate, which fully mixes with the sewage that continuously enters the inner cavity of the storage shell, enhancing the reaction effect between the agent and the sewage, ensuring that pollutants such as steel slag and colloids are fully flocculated, laying the foundation for subsequent adsorption treatment.

[0012] Preferably, the mixing component includes three mesh plates, which are sequentially arranged inside the main body shell. The sides of the mesh plates are fixedly connected to the inside of the main body shell. A rotating rod is rotatably connected to the inner side of the upper mesh plate, and the bottom of the rotating rod is rotatably connected to the top of the lower mesh plate. A cleaning brush is sleeved on the side of the rotating shaft near the mesh plate, and the side of the cleaning brush contacts the mesh plate. Cleaning mechanisms are evenly arranged on the side of the rotating rod, and the top of the rotating rod is fixedly connected to the bottom of the rotating shaft.

[0013] Preferably, after the wastewater continuously enters the inner cavity of the main body shell through the mesh plate, the output end of the drive component drives the rotating shaft to rotate. At the same time, the rotating shaft drives the rotating rod to rotate synchronously in the inner cavity of the main body shell. When the rotating rod rotates, it will drive the cleaning mechanism to fully mix and stir the wastewater mixed with the agent, accelerate the reaction rate of the agent and the pollutants in the wastewater, shorten the flocculation reaction time, and improve the impurity coagulation efficiency.

[0014] Preferably, the cleaning mechanism includes a rotating frame, the side of the rotating frame is fixedly connected to the inner side of the rotating rod, a fixed rod is fixedly connected to the inner side of the rotating frame, a sliding shaft is slidably connected to the inner side of the fixed rod, a scraper is fixedly connected to the other end of the sliding shaft, the side of the scraper is slidably connected to the inner side of the rotating frame, a second spring is sleeved on the sliding shaft, one end of the second spring is fixedly connected to the side of the fixed rod, and the other end of the second spring is fixedly connected to the side of the scraper near the sliding shaft;

[0015] Preferably, when the rotating rod rotates with the rotating shaft, it will cause the rotating frame to come into full contact with and stir the wastewater that has entered the main body shell and has been mixed with the agent, thereby accelerating the reaction between the wastewater and the agent, shortening the flocculation time, and improving the efficiency of impurity coagulation.

[0016] Preferably, the adsorption component includes a magnetic filter screen, the top of which is fixedly connected to the bottom of the lower mesh plate two, a rotating shaft is rotatably connected to the inner side of the top of the magnetic filter screen, the top of which is fixedly connected to the bottom of the rotating rod, a collecting mechanism is fixedly connected to the bottom of the rotating shaft, the bottom of the collecting mechanism is rotatably connected to the bottom of the inner cavity of the magnetic filter screen, a motor is fixedly connected to the bottom of the magnetic filter screen, and a contact mechanism is fixedly connected to the side of the collecting mechanism.

[0017] Preferably, the wastewater passing through the second mesh plate continues to flow downward under the action of gravity and enters the magnetic filter screen. At this time, the magnetic filter screen uses magnetism to adsorb the steel slag mixed in the wastewater, separating the steel slag from the wastewater, reducing the impurity load for subsequent treatment, and achieving the initial recovery of steel slag.

[0018] Preferably, the collection mechanism includes a collection housing, the top of which is fixedly connected to the bottom of the rotating shaft, the bottom of which is rotatably connected to the bottom of the inner cavity of the magnetic filter, a magnetic mesh plate fixedly connected to the bottom of the inner cavity of the collection housing, a rotating assembly rotatably connected to the middle of the top of the magnetic mesh plate, and a one-way valve fixedly connected to both sides of the collection housing.

[0019] Preferably, when the suction assembly is working, the steel slag in the feed trough is sent into the inner cavity of the collection shell through the suction pipe for collection. During this process, sewage will enter along with the steel slag. Since there are one-way valves on both sides of the collection shell, the sewage in the inner cavity can be discharged through the one-way valves to avoid sewage from stagnating in the collection shell, prevent interference with the collection and subsequent processing of steel slag, and ensure the independence and efficiency of the collection process.

[0020] Preferably, the contact mechanism includes an air suction pipe and a push plate. The side of the air suction pipe is fixedly connected to the inner side of the collection shell, and an air suction component is fixedly connected to one end of the air suction pipe. The side of the push plate is fixedly connected to the collection shell, and feeding grooves are provided on both sides of the push plate. A scraper is fixedly connected to the bottom of the feeding groove, and the bottom of the scraper contacts the bottom of the inner cavity of the magnetic filter. The end of the air suction pipe away from the collection shell is fixedly connected to the inner side of the push plate.

[0021] Preferably, when wastewater continuously passes through the magnetic filter, the magnetic filter adsorbs the steel slag in the wastewater, separates the steel slag from the wastewater, reduces the impurity load on subsequent treatment equipment, and lays the foundation for the resource recycling of steel slag.

[0022] Preferably, the rotating assembly includes a round rod, the top of which is rotatably connected to the top of the inner cavity of the collecting shell, the side of which is rotatably connected to the inner side of the magnetic mesh plate, the bottom of which is fixedly connected to the output end of the motor, a round shaft fixedly connected to the middle of the side of the round rod, connecting frames fixedly connected to both sides of the round shaft, and inclined plates fixedly connected to both sides of the connecting frames, with the side of the inclined plate away from the connecting frame contacting the top of the magnetic mesh plate.

[0023] This invention provides a pre-treatment equipment for steelmaking wastewater. It has the following beneficial effects:

[0024] 1. This pre-treatment steelmaking wastewater treatment equipment is equipped with a material storage mechanism. The rotating shaft drives the spiral blades to rotate, which fully mixes with the wastewater that continuously enters the inner cavity of the material storage shell. This enhances the reaction effect between the reagent and the wastewater, ensuring that pollutants such as steel slag and colloids are fully flocculated, laying the foundation for subsequent adsorption treatment.

[0025] 2. This pre-treatment steelmaking wastewater treatment equipment is equipped with a cleaning mechanism. Under centrifugal force, the sliding shaft drives the scraper to slide inside the rotating frame, while simultaneously stretching the second spring on the sliding shaft. This ensures that the scraper is in close contact with the inner wall of the main body shell and rotates with the rotating frame. The continuous cleaning of the inner wall by the scraper prevents sludge and impurities from accumulating on the wall surface when the wastewater flows through the main body shell. This reduces the workload of manual cleaning in the later stages and prevents impurities from affecting the equipment's flow efficiency, ensuring the long-term stable operation of the main body shell.

[0026] 3. This pre-treatment steelmaking wastewater treatment equipment is equipped with a contact mechanism. The rotating shaft drives the collection shell to rotate, and the collection shell synchronously drives the push plate to rotate at the bottom of the inner cavity of the magnetic filter. Since there is a scraper at the bottom of the push plate, the scraper will scrape the steel slag adsorbed at the bottom of the inner cavity of the magnetic filter as the push plate rotates, so as to remove the steel slag adhering to the surface of the filter in time, avoid its accumulation and blockage of the filter pores, and ensure the continuous and efficient adsorption of the filter.

[0027] 4. This pre-treatment steelmaking wastewater treatment equipment is equipped with a collection mechanism. When the suction component is working, the steel slag in the feed trough is sent into the inner cavity of the collection shell through the suction pipe. During this process, wastewater will enter along with the steel slag. Since there are one-way valves on both sides of the collection shell, the wastewater in the inner cavity can be discharged through the one-way valves, avoiding the retention of wastewater in the collection shell, preventing interference with the collection and subsequent treatment of steel slag, and ensuring the independence and efficiency of the collection process.

[0028] 5. This pre-treatment steelmaking wastewater treatment equipment is equipped with a rotating component. The inclined plate will push the steel slag accumulated on the magnetic mesh plate to flatten it, avoiding local accumulation of steel slag that would block the adsorption surface of the magnetic mesh plate. This ensures that the mesh plate always maintains a large adsorption area and a stable steel slag adsorption efficiency, while also facilitating the subsequent centralized cleaning of steel slag.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-2 The present invention provides a technical solution: a pre-treatment steelmaking wastewater treatment device, comprising:

[0041] The main body shell 1 has water outlet pipes 3 fixedly connected to both sides of the main body shell 1, and a mixing component 4 is rotatably connected to the inside of the main body shell 1. An adsorption component 5 is fixedly connected to the bottom of the mixing component 4.

[0042] Feeding component 2 is used to add chemicals to steelmaking wastewater. The bottom of the feeding component 2 is fixedly connected to the top of the main body shell 1.

[0043] Please see Figures 1-3 The feeding component 2 includes a material storage shell 21. The bottom of the material storage shell 21 is fixedly connected to the top of the main shell 1. A driving component 23 is fixedly connected to the top of the material storage shell 21. A mesh plate 25 is fixedly connected to the bottom of the material storage shell 21. Feed pipes 22 are fixedly connected to both sides of the top of the material storage shell 21. Water inlet pipes 24 are fixedly connected to both sides of the material storage shell 21. A material storage mechanism 26 is rotatably connected to the middle of the inner cavity of the material storage shell 21.

[0044] An appropriate amount of reagent is added into the storage shell 21 through the feed pipe 22. After entering through the feed pipe 22, the reagent is temporarily stored in the storage mechanism 26. At the same time, sewage is continuously fed into the inner cavity of the storage shell 21 through the water inlet pipe 24. Then, the drive unit 23 is turned on, and the output end of the drive unit 23 will drive the storage mechanism 26 to move, adding a quantitative amount of reagent to the sewage entering the storage shell 21, completing the initial combination of reagent and sewage.

[0045] Please see Figures 1-4 The material storage mechanism 26 includes a rotating shaft 261 and a baffle plate 267. The side of the rotating shaft 261 is rotatably connected to the top of the inner cavity of the material storage housing 21. The top of the rotating shaft 261 is fixedly connected to the output end of the drive component 23. The side of the rotating shaft 261 is rotatably connected to the inner side of the mesh plate 25. A connecting shaft 262 is fixedly connected to the side of the rotating shaft 261. Sliding rods 263 are slidably connected to both sides of the connecting shaft 262. A stop block 264 is fixedly connected to the bottom of the sliding rod 263. The side of the stop block 264 is connected to the baffle plate 267. The inner sides of the slide bar 263 are in contact with each other. A first spring 265 is sleeved on the slide bar 263. The top of the first spring 265 is fixedly connected to the side of the connecting shaft 262. The bottom of the first spring 265 is fixedly connected to the top of the stop block 264. The side of the baffle plate 267 is fixedly connected to the middle of the inner cavity of the storage shell 21. A spiral blade 268 is fixedly connected to the side of the rotating shaft 261 away from the connecting shaft 262. A cleaning brush 266 is fixedly connected to the side of the rotating shaft 261. The side of the cleaning brush 266 is in contact with the top of the screen plate 25.

[0046] When wastewater continuously enters the storage shell 21 through the inlet pipe 24, the drive unit 23 is activated, and its output end drives the rotating shaft 261 to rotate. In turn, the rotating shaft 261 drives the connecting shaft 262 to rotate synchronously in the inner cavity of the storage shell 21. When the connecting shaft 262 rotates, the slide rod 263 drives the stop block 264 to disengage from the baffle plate 267, so that the agent originally stored on the top of the baffle plate 267 falls into the wastewater, realizing the automatic mixing of the agent and the wastewater. There is no need for manual addition of the agent, which improves the accuracy and efficiency of the dosing and reduces the cost of manual operation.

[0047] At the same time, the rotating shaft 261 drives the spiral blade 268 to rotate, which fully mixes with the sewage that continuously enters the inner cavity of the storage shell 21, enhances the reaction effect between the agent and the sewage, and ensures that pollutants such as steel slag and colloids are fully flocculated, laying the foundation for subsequent adsorption treatment.

[0048] In addition, when the rotating shaft 261 rotates, it simultaneously drives the cleaning brush 266 to contact and rub against the top of the screen plate 25. When sewage enters the inner cavity of the main body shell 1 through the screen plate 25, the cleaning brush 266 can remove impurities on the surface of the screen plate 25 in time, avoid the problem of screen plate blockage caused by long-term attachment of impurities, ensure smooth sewage flow, reduce the frequency of equipment shutdown for cleaning, and improve overall treatment efficiency.

[0049] Please see Figures 1-5 The present invention provides a technical solution: the mixing component 4 includes three mesh plates 41, which are arranged sequentially inside the main body shell 1. The sides of the mesh plates 41 are fixedly connected to the inside of the main body shell 1. A rotating rod 42 is rotatably connected to the inside of the upper mesh plate 41. The bottom of the rotating rod 42 is rotatably connected to the top of the lower mesh plate 41. A cleaning brush 43 is sleeved on the side of the rotating shaft 261 near the mesh plate 41. The side of the cleaning brush 43 is in contact with the mesh plate 41. A cleaning mechanism 44 is evenly arranged on the side of the rotating rod 42. The top of the rotating rod 42 is fixedly connected to the bottom of the rotating shaft 261.

[0050] After the wastewater continuously enters the inner cavity of the main body shell 1 through the mesh plate 25, the output end of the drive component 23 drives the rotating shaft 261 to rotate. At the same time, the rotating shaft 261 drives the rotating rod 42 to rotate synchronously in the inner cavity of the main body shell 1. When the rotating rod 42 rotates, it will drive the cleaning mechanism 44 to fully mix and stir the wastewater mixed with the agent, accelerate the reaction rate of the agent and the pollutants in the wastewater, shorten the flocculation reaction time, and improve the impurity coagulation efficiency.

[0051] At the same time, when the rotating rod 42 rotates, it will also drive the second cleaning brush 43 to contact and clean the side of the second screen plate 41, which can remove the impurities attached to the second screen plate 41 due to the flocculation reaction in time, avoid the second screen plate 41 from being blocked, and ensure smooth sewage flow.

[0052] Please see Figures 1-6 The cleaning mechanism 44 includes a rotating frame 441. The side of the rotating frame 441 is fixedly connected to the inner side of the rotating rod 42. A fixed rod 442 is fixedly connected to the inner side of the rotating frame 441. A sliding shaft 443 is slidably connected to the inner side of the fixed rod 442. A scraper 444 is fixedly connected to the other end of the sliding shaft 443. The side of the scraper 444 is slidably connected to the inner side of the rotating frame 441. A second spring 445 is sleeved on the sliding shaft 443. One end of the second spring 445 is fixedly connected to the side of the fixed rod 442. The other end of the second spring 445 is fixedly connected to the side of the scraper 444 near the sliding shaft 443.

[0053] When the rotating rod 42 rotates with the rotating shaft 261, it will drive the rotating frame 441 to fully contact and stir the wastewater that has entered the main body shell 1 and mixed with the agent, thereby accelerating the reaction between the wastewater and the agent, shortening the flocculation time, and improving the efficiency of impurity coagulation.

[0054] Meanwhile, under the action of centrifugal force, the sliding shaft 443 will drive the scraper 444 to slide inside the rotating frame 441, and at the same time stretch the second spring 445 on the sliding shaft 443, so that the scraper 444 is in close contact with the inner wall of the main body shell 1 and rotates with the rotating frame 441. The continuous cleaning of the inner wall by the scraper 444 avoids the accumulation of sludge and impurities on the wall surface when sewage flows through the main body shell 1, which not only reduces the amount of manual cleaning in the later stage, but also prevents impurities from adhering and affecting the flow efficiency of the equipment, and ensures the long-term stable operation of the main body shell 1.

[0055] Please see Figures 1-7 The present invention provides a technical solution: the adsorption component 5 includes a magnetic filter 51, the top of the magnetic filter 51 is fixedly connected to the bottom of the lower mesh plate 41, a rotating shaft 52 is rotatably connected to the inner side of the top of the magnetic filter 51, the top of the rotating shaft 52 is fixedly connected to the bottom of the rotating rod 42, a collection mechanism 54 is fixedly connected to the bottom of the rotating shaft 52, the bottom of the collection mechanism 54 is rotatably connected to the bottom of the inner cavity of the magnetic filter 51, a motor 53 is fixedly connected to the bottom of the magnetic filter 51, and a contact mechanism 55 is fixedly connected to the side of the collection mechanism 54;

[0056] Wastewater passing through screen 41 continues to flow downward under the action of gravity and enters magnetic filter 51. At this time, magnetic filter 51 uses magnetism to adsorb the steel slag mixed in the wastewater, separating the steel slag from the wastewater, reducing the impurity load for subsequent treatment, and achieving the initial recovery of steel slag.

[0057] At the same time, when the rotating rod 42 rotates, it drives the rotating shaft 52 to rotate synchronously, so that the rotating shaft 52 drives the collection mechanism 54 and the contact mechanism 55 to rotate in the inner cavity of the magnetic filter screen 51, so as to collect the impurities adsorbed by the filter screen in time, avoid the impurities from accumulating excessively on the magnetic filter screen 51 and affecting the adsorption efficiency, ensure the continuous and stable operation of the filter screen, reduce the frequency of manual cleaning, and improve the continuity of the overall processing flow.

[0058] Please see Figures 1-8 The contact mechanism 55 includes a suction pipe 551 and a push plate 553. The side of the suction pipe 551 is fixedly connected to the inside of the collection shell 541. A suction component 552 is fixedly connected to one end of the suction pipe 551. The side of the push plate 553 is fixedly connected to the collection shell 541. Feeding grooves 555 are provided on both sides of the push plate 553. A scraper 554 is fixedly connected to the bottom of the feeding groove 555. The bottom of the scraper 554 is in contact with the bottom of the inner cavity of the magnetic filter screen 51. The end of the suction pipe 551 away from the collection shell 541 is fixedly connected to the inside of the push plate 553.

[0059] When wastewater continuously passes through the magnetic filter 51, the magnetic filter 51 adsorbs the steel slag in the wastewater, separates the steel slag from the wastewater, reduces the impurity load on subsequent treatment equipment, and lays the foundation for the resource recycling of steel slag.

[0060] The rotating shaft 52 drives the collection shell 541 to rotate, and the collection shell 541 synchronously drives the push plate 553 to rotate at the bottom of the inner cavity of the magnetic filter screen 51. Since the bottom of the push plate 553 is equipped with a scraper 554, the scraper 554 will scrape the steel slag adsorbed at the bottom of the inner cavity of the magnetic filter screen 51 as the push plate 553 rotates, so as to remove the steel slag adhering to the surface of the filter screen in time, avoid its accumulation and blockage of the filter screen pores, and ensure the continuous and efficient adsorption of the filter screen.

[0061] Meanwhile, the feed trough 555 on the side of the push plate 553 can receive the steel slag scraped off by the scraper 554, allowing the steel slag to enter the trough smoothly. At this time, the suction component 552 is turned on, and the suction force generated by its operation is used to suck the steel slag in the feed trough 555 into the collection shell 541 through the suction pipe 551 for centralized collection, reducing the amount of manual cleaning work, and preventing the steel slag from scattering back into the sewage during the collection process, thus improving the steel slag recycling efficiency and the continuity of the overall treatment process.

[0062] Please see Figures 1-8 The collection mechanism 54 includes a collection housing 541, the top of which is fixedly connected to the bottom of the rotating shaft 52, the bottom of which is rotatably connected to the bottom of the inner cavity of the magnetic filter screen 51, a magnetic mesh plate 542 fixedly connected to the bottom of the inner cavity of the collection housing 541, a rotating assembly 544 rotatably connected to the middle of the top of the magnetic mesh plate 542, and a one-way valve 543 fixedly connected to both sides of the collection housing 541.

[0063] When the suction assembly 552 is working, the steel slag in the feed trough 555 is sent into the inner cavity of the collection shell 541 through the suction pipe 551 for collection. During this process, sewage will enter along with the steel slag. Since there are one-way valves 543 on both sides of the collection shell 541, the sewage in the inner cavity can be discharged through the one-way valves 543 to prevent sewage from stagnating in the collection shell 541, prevent interference with the collection and subsequent processing of steel slag, and ensure the independence and efficiency of the collection process.

[0064] The steel slag entering the collection shell 541 is adsorbed onto the magnetic mesh plate 542, which can prevent the steel slag from entering the one-way valve 543 with the discharged sewage and causing blockage. At the same time, it realizes the secondary separation of steel slag and sewage, and improves the purity of steel slag collection.

[0065] In addition, after the motor 53 is turned on, its output end drives the rotating component 544 to rotate inside the collection shell 541, which flattens the steel slag adsorbed on the magnetic mesh plate 542, avoids the local accumulation of steel slag affecting the adsorption capacity of the magnetic mesh plate 542, ensures the maximum utilization of the mesh plate surface, and maintains a continuous and stable steel slag collection effect.

[0066] Please see Figures 1-9The rotating assembly 544 includes a round rod 5441. The top of the round rod 5441 is rotatably connected to the top of the inner cavity of the collecting shell 541. The side of the round rod 5441 is rotatably connected to the inner side of the magnetic mesh plate 542. The bottom of the round rod 5441 is fixedly connected to the output end of the motor 53. A round shaft 5442 is fixedly connected to the middle of the side of the round rod 5441. A connecting frame 5443 is fixedly connected to both sides of the round shaft 5442. An inclined plate 5444 is fixedly connected to both sides of the connecting frame 5443. The side of the inclined plate 5444 away from the connecting frame 5443 is in contact with the top of the magnetic mesh plate 542.

[0067] The output end of motor 53 drives the round rod 5441 to rotate on the magnetic mesh plate 542. The round rod 5441 then drives the round shaft 5442 to rotate. The round shaft 5442, through the connecting frame 5443, drives the inclined plate 5444 to rotate synchronously on the magnetic mesh plate 542. The inclined plate 5444 will push the steel slag accumulated on the magnetic mesh plate 542 to flatten it, avoiding the local accumulation of steel slag and blocking the adsorption surface of the magnetic mesh plate 542. This ensures that the mesh plate always maintains a large adsorption area and maintains a stable steel slag adsorption efficiency. It also facilitates the subsequent centralized cleaning of steel slag.

[0068] Specific workflow:

[0069] First, the wastewater is introduced into the main body shell 1 through the feeding component 2. At the same time as the wastewater enters the feeding component 2, a large amount of reagent is added to the wastewater. Then, the mixing component 4 fully mixes the wastewater mixed with the reagent to ensure that the reagent reacts fully with the pollutants in the wastewater.

[0070] As the wastewater flows continuously downward inside the main body shell 1 and enters the adsorption component 5, the adsorption component 5 adsorbs and collects the steel slag in the wastewater. The wastewater that has been adsorbed is finally discharged through the outlet pipes 3 on both sides of the main body shell 1, preparing for the subsequent deep treatment process.

[0071] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
