Description

Technical Field

[0001] This utility model relates to the field of magnetic filter technology, and in particular to a magnetic filter with a movable scraping magnetic cleaning function. Background Technology

[0002] In modern industrial production, various ferromagnetic industrial fluids require efficient solid-liquid separation. For example, wastewater from ferric phosphate production lines contains a large amount of ferromagnetic micro-suspended solids; ferric phosphate production also contains a large amount of iron particle impurities. For the wastewater generated during ferric phosphate production, it is usually necessary to remove the ferromagnetic micro-suspended solids to meet wastewater discharge standards; otherwise, the discharged wastewater will pollute the environment and waste ferromagnetic components. For ferric phosphate products, the large amount of iron particle impurities needs to be removed to improve the purity of the produced ferric phosphate product. Therefore, in the ferric phosphate production process, the discharged ferromagnetic wastewater and ferric phosphate slurry containing iron particle impurities are usually filtered using existing magnetic filters. A magnetization-demagnetization-cleaning process is used to remove the ferromagnetic components from the wastewater or the iron particle impurities from the ferric phosphate slurry.

[0003] Currently, there are relatively many disclosed magnetic filter structures in existing technologies. For example, patent publication number CN114918040B discloses an automatic iron remover for high-viscosity slurry, including a filtration chamber, a cleaning chamber, and a magnetic rod assembly. The magnetic rod assembly includes a lifting disc, a filter cake disc, a lifting disc power unit, a filter cake disc power unit, and several magnetic rods. The top of each magnetic rod is provided with a tip that cooperates with the magnetic rod positioning seat. The magnetic rod is divided into a magnetic area and a non-magnetic area, wherein the length of the magnetic area of ​​the magnetic rod is much longer than the length of the non-magnetic area. The non-magnetic area of ​​the magnetic rod is only the area above the tip, and the rest is the magnetic area. The filter cake disc is located directly below the lifting disc. The lifting disc power unit includes a lifting disc cylinder located above the cleaning chamber, and the filter cake disc power unit includes a filter cake disc cylinder located above the cleaning chamber. The lifting disc cylinder is connected to the lifting disc through a lifting disc rod, and the filter cake disc cylinder is connected to the filter cake disc through a filter cake disc rod, which passes through the lifting disc. The filter cake is coiled with a retaining ring, and a sealing contact ring is provided on the outer edge of the filter cake. The sealing contact ring has air pressure holes, and a fixing post for fixing the filter cake is also provided on the filter cake. Magnetic rods are evenly arranged circumferentially below the lifting plate, passing through the filter cake. A filter cake device is provided on the filter cake, which is in close contact with the magnetic rods. The filter cake device includes a fixing part and a filter cake part, with the fixing part located above the filter cake part. A scraping ring is provided on the filter cake part, which contacts the magnetic rods and has an opening whose radius gradually decreases from bottom to top. Several sealing rings with interference fit to the magnetic rods are provided on the fixing part, allowing the filter chamber to operate for extended periods without material replacement, thus eliminating the need for cleaning. Combined with scraping methods to remove impurities from the magnetic rods, this reduces the consumption of cleaning liquid and drying gas.

[0004] For example, patent publication number CN118558035A discloses a mobile cleaning device for a reaction vessel with solid-liquid separation, including a workbench and a processing tank fixedly installed at its bottom, and a magnetic filter block with a magnetic attraction structure on its top, which is fixedly installed on the top of the processing tank. A slag discharge scraper is inserted and slidably installed on the magnetic filter block. The top of the slag discharge scraper is a right-angled triangular prism and slides on the upper surface of the magnetic filter block. The right-angled side of the right-angled triangular prism of the slag discharge scraper is set downwards, and the hypotenuse is set upwards. The magnetic filter block is set in a downward inclined position, and a limiter is fixedly installed on the inclined surface of the magnetic filter block. The column has an elastic element between the top of the slag discharge scraper and the limiting column. The lower half of the magnetic filter block is set as a cavity, forming an open and closed cavity with the sliding slag discharge scraper. By setting the magnetic filter block and the slag discharge scraper, the magnetic attraction of the magnetic filter block is used to adsorb and intercept the metal impurities generated after high-pressure cleaning. The slag discharge scraper then scrapes the metal impurities adsorbed on the magnetic filter block into the cavity, thereby achieving solid-liquid separation of the metal impurities after high-pressure cleaning, which can improve work efficiency. The separation mechanism separates the impurities after high-pressure cleaning into three categories: metal impurities, solid impurities, and liquid impurities for separate collection and processing.

[0005] For example, patent publication number CN106457260B discloses a magnetic filter and a method for removing magnetic substances. The magnetic filter includes an outer cylinder and an inner cylinder, a filter chamber, and a magnetic unit rod. The outer cylinder and the inner cylinder are arranged concentrically. The filter chamber is formed in the gap between the outer cylinder and the inner cylinder. The magnetic unit rod is detachably housed inside the inner cylinder. Magnetic substances mixed in the filtrate flowing into the filter chamber are attracted to the outer peripheral side of the inner cylinder by the magnetic force of the magnetic unit rod housed in the inner cylinder. A scraper with a scraping part is provided in the filter chamber. The scraping part abuts against the outer peripheral side of the inner cylinder. When the scraper is activated, the scraping part slides along the outer peripheral side of the inner cylinder to scrape off the magnetic substances attracted to the inner cylinder.

[0006] It is evident that existing technologies have already conducted relevant research on magnetic filters. However, in the production process of ferric phosphate, conventional filtration methods are insufficient to remove iron particle impurities, making the removal of iron particle impurities quite difficult; moreover, traditional single-cylinder filtration has low efficiency and poor performance. Utility Model Content

[0007] To address the aforementioned technical issues, this invention provides a magnetic filter with a movable scraping magnetic cleaning function.

[0008] The specific technical solution is as follows:

[0009] A magnetic filter with movable magnetic scraping cleaning includes a frame, a magnetic cleaning assembly installed inside the frame, and a lifting and traversing assembly installed at the top of the frame.

[0010] By installing a magnetic cleaning component inside the frame and a lifting and traversing component at the top of the frame, the magnetic cleaning component is controlled by the lifting and traversing component. This allows the magnetic scraping component, after being magnetically filtered in the magnetic filter cylinder to remove slurry or liquid containing iron particles, to be transferred to the cleaning tank for cleaning and demagnetization before returning to the magnetic filter cylinder for further magnetic filtration. Introducing this scraping-cleaning process helps reduce the difficulty of removing iron particles and improves the efficiency of iron particle removal through filtration.

[0011] To simplify the scraping process and ensure a tight fit on the magnetic filter cylinder, the magnetic scraping component preferably includes a scraper and a cover that adheres to the upper surface of the scraper. The cover has several magnetic rod mounting positions, and the scraper has several magnetic rod through holes corresponding to the mounting positions. Magnetic rods are installed in the through holes, with the inner wall of the through hole fitting against the outer wall of the magnetic rod, and the top of the magnetic rod is fixedly connected to the mounting position. The scraper has a gripping element that can grip the magnetic filter cylinder. The scraper is fixedly connected to the bottom end of the lifting component. More preferably, the gripping element can be made of an elastic metal sheet, which helps to ensure a tight grip and also reduces the difficulty of lifting the lifting component to detach the gripping element from the top of the magnetic filter cylinder.

[0012] To reduce cleaning difficulty, preferably, the bottom end of the magnetic rod has a non-magnetic section. More preferably, the height of the non-magnetic section is 3-10cm.

[0013] In order to control the lifting and lowering of the magnetic attracting and scraping component, and to enable it to move laterally as a whole after being raised to the appropriate position, preferably, the lifting component includes a lifting screw, a lifting device, and a lifting motor. The lifting device is mounted on the lateral component and is connected to the lifting screw. The lifting device is connected to the lifting motor, and the lifting motor can control the lifting device, so that the lifting screw moves up and down under the action of the lifting device. The bottom end of the lifting screw is provided with a connecting member, which connects the lifting screw to the magnetic attracting and scraping component.

[0014] To ensure the stability of the lateral movement component at the top of the frame and guarantee stability during the lateral movement process, the lateral movement component preferably includes a sliding assembly and a lateral movement bracket mounted on the top of the frame. The lateral movement bracket is equipped with a lateral movement screw, and a lateral movement motor is connected to the lateral movement screw, which is also connected to the sliding assembly. The lifting component is mounted on the sliding assembly, and the lateral movement motor can control the lateral movement screw, causing the sliding assembly to move laterally at the top of the frame.

[0015] To ensure lateral movement at the top of the frame, allowing the lifting component to move as a whole with the lateral component and improving stability, the sliding assembly preferably includes a slide rail disposed at the top of the frame, a slider matched and connected to the slide rail, and a support platform mounted on or integrally formed with the slider; the lifting component is mounted on the support platform, and the slider can slide freely on the slide rail.

[0016] To enhance installation stability, preferably, the frame includes a crossbar, and both the cleaning tank and the magnetic filter cartridge are mounted on the crossbar. More preferably, the crossbar has several mounting seats for mounting the cleaning tank and the magnetic filter cartridge.

[0017] To improve the magnetic filtration effect and increase the efficiency of removing iron particles from the slurry, preferably, the magnetic filter cylinder consists of two cylindrical cylinders, each with a bottom seal. An inlet is located near the bottom of one cylindrical cylinder, and an outlet is located near the top of the other cylindrical cylinder. A connecting pipe connects the outlet on the left cylindrical cylinder to the inlet on the right cylindrical cylinder. The magnetic scraping component is installed inside each cylindrical cylinder and can be lifted from the top of the cylinder or inserted into it under the action of the lifting component. The cleaning tank is matched with the magnetic filter cylinder and, under the action of the lifting and lateral components, can lift and laterally move the magnetic scraping component inside the cylindrical cylinder into the cleaning tank for cleaning. The magnetic scraping component can fit and cover the top of the cleaning tank during magnetic scraping and cleaning. More preferably, there can be several magnetic filter cylinders.

[0018] To ensure that the magnetic components are scraped to the bottom of the magnetic rod after the magnetic scraping process, and to ensure that the travel of the lifting component at the top of the magnetic filter cylinder is consistent with its travel at the top of the cleaning tank, a portion of the bottom of the magnetic rod can be inserted into the cleaning tank and rinsed off, preferably, the height between the top of the cleaning tank and the bottom of the frame is higher than the height between the magnetic filter cylinder and the bottom of the frame.

[0019] In order to achieve automated control of the magnetic attraction-scraping-cleaning operation, preferably, the frame is provided with a fixed bracket and a fixed rod, and a PCL controller is installed on the fixed bracket and the fixed rod. The PCL controller is connected to the lifting component and the traversing component via an electrical signal.

[0020] To better achieve the scraping and cleaning process and avoid the magnetic rod becoming difficult to scrape as it moves down with the scraper, preferably, the transverse moving member has a locking member located directly above the cleaning tank, and the cover has a hook that matches the locking member; the hook can connect with the locking member after being lifted to the top of the frame by the lifting member, so that the cover is fixed to the top of the frame; and disengage from the locking member during the transverse moving to the top of the magnetic filter cylinder, so that the cover can detach from the top of the frame.

[0021] Compared with the prior art, the technical effects of this invention are reflected in:

[0022] This invention features a simple structure, is easy to operate, and is more likely to be industrialized and promoted. Moreover, it utilizes magnetic attraction, scraping, and washing tank rinsing to achieve magnetic filtration and removal, which reduces the difficulty of removing iron particle impurities and helps to improve removal efficiency.

[0023] This invention utilizes two or more cylinders connected in series between the liquid outlet and the liquid inlet to form multiple magnetic absorption processes, which helps to improve the efficiency of magnetic filtration and removal of iron-containing particles.

[0024] This invention creates a magnetic rod mounting position on a cover, and installs a magnetic rod on the mounting position, so that the top of the magnetic rod is fixedly connected to the cover. Then, a magnetic rod through hole is set on the scraper at the position corresponding to the magnetic rod mounting position. The magnetic rod extends into the magnetic rod through the through hole. Then, by utilizing the relative movement between the scraper and the cover, the wall of the through hole and the magnetic rod can come into contact with each other to achieve scraping. This scrapes the iron particles on the magnetic rod to the bottom of the magnetic rod. So, when it is sent into the cleaning tank for rinsing, the bottom of the magnetic rod enters the cleaning tank. This helps to reduce the amount of water used in the cleaning tank and reduce the size of the cleaning tank, thereby reducing the manufacturing cost of the device and the application cost of the cleaning process.

[0035] To facilitate a correct understanding of the present invention by those skilled in the art, and to enable them to fully understand the technical content of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments. However, this description does not limit the scope of protection claimed by the present invention. Those skilled in the art should not limit the scope of protection of the present invention to the following description. Any equivalent substitutions or changes made by those skilled in the art or those familiar with the art based on the present invention, and based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

[0036] like Figures 1 to 3As shown, in some embodiments, a magnetic filter with movable scraping magnetic cleaning includes a frame 1, in which a magnetic cleaning assembly is installed. A lifting and traversing assembly is installed at the top of the frame 1. The magnetic cleaning assembly includes a cleaning tank 19, a magnetic filter cylinder 4, and a magnetic scraping component. The lifting and traversing assembly includes a lifting component and a traversing component. The bottom end of the lifting component is connected to the magnetic scraping component, and the traversing component is connected to the lifting component and can move laterally after the lifting component reaches its highest point, so that the magnetic scraping component can move back and forth between the magnetic filter cylinder 4 and the cleaning tank 19.

[0037] When the device is running, such as Figures 4 to 7 As shown, during the initial magnetization... Figure 4 The structure shown has a transverse component that moves at the top of the frame 1, causing the lifting component to move to its maximum value (536mm) near the right side of the frame. The lifting component then moves downwards, allowing the magnetic attracting and scraping component to extend from the top of the magnetic filter cylinder 4. After magnetic attraction is complete, the lifting component raises the magnetic attracting and scraping component until it reaches its highest position (e.g., ...). Figure 5 As shown: the height from the top of the magnetic filter cylinder 4 is 998mm), and the magnetic suction and scraping component is completely lifted out of the magnetic filter cylinder 4; under the action of the lateral movement component, the lifting component and the magnetic suction and scraping component are moved laterally as a whole to directly above the cleaning tank 19 (e.g., Figure 6 As shown, the distance between the center line of the magnetic filter cylinder 4 and the center line of the cleaning tank 19 is 433mm; under the action of the lifting component, the magnetic scraping component performs scraping treatment, and as the lifting component descends, it enters the cleaning tank 19, forming a... Figure 7 The structure shown is followed by rinsing with clean water pumped into the cleaning tank 19. The cleaning tank 19 used in this invention has several pump inlets on its side wall for pumping in clean water, and a cleaning liquid outlet at the bottom, which is connected to a waste collection tank. This facilitates rinsing the magnetic suction and scraping components with clean water pumped in from several directions within the cleaning tank 19, thus improving cleaning efficiency and effectiveness.

[0038] like Figures 1 to 3As shown, in some embodiments, the magnetic suction and scraping component includes a scraper 5 and a cover 9 that can adhere to the upper surface of the scraper 5. The cover 9 is provided with a plurality of magnetic rod mounting positions 8, and the scraper 5 is provided with a plurality of magnetic rod through holes at positions corresponding to the magnetic rod mounting positions 8. A magnetic rod is installed in the magnetic rod through hole, the inner wall of the magnetic rod through hole is attached to the outer wall of the magnetic rod, and the top end of the magnetic rod is fixedly connected to the magnetic rod mounting position. The scraper 5 is provided with a gripping member 7 that can grip the magnetic suction filter cylinder 4. The scraper 5 is fixedly connected to the bottom end of the lifting component. During magnetic suction filtration, the entire magnetic suction and scraping component is moved downward onto the magnetic suction filter cylinder 4 under the action of the lifting component, so that the magnetic suction and scraping component extends into the magnetic suction filter cylinder 4 until the magnetic rod is completely inserted into the magnetic suction filter cylinder 4, so that the gap between the scraper 5 and the magnetic suction filter cylinder 4 is only 4mm (e.g., Figure 4 When (as shown), the gripping member 7 grips the top edge of the magnetic filter cylinder 4. At this time, the cap 9 descends under its own gravity, pressing the magnetic rod into the magnetic filter cylinder 4. After the slurry to be treated enters the magnetic filter cylinder 4, it adsorbs iron particle impurities under the action of the magnetic rod. After the adsorption value reaches its maximum, the lifting member lifts the entire magnetic scraping member until it is completely lifted out of the magnetic filter cylinder 4 and raised to the highest point (as shown). Figure 5 As shown), the magnetic filtering process is achieved, combined with, for example, Figure 6 He Ru Figure 7 The operating principle shown is used to achieve cleaning and removal of the magnetic rod.

[0039] This invention achieves automatic magnetic scraping and improves the scraping effect through the following technical solution during the magnetic scraping process: A locking component (not shown in the figure) is provided on the transverse moving member directly above the cleaning tank 19, and the cover 9 is provided with a hook (not shown in the figure) that matches the locking component; the hook can connect with the locking component after being lifted to the top of the frame 1 by the lifting member, so that the cover 9 is fixed to the top of the frame 1 when the transverse moving member moves directly above the cleaning tank 19; during the transverse movement to directly above the magnetic filter cylinder 4, the hook disengages from the locking component, allowing the cover 9 to detach from the top of the frame 1. By utilizing the hook and locking component, the cover 9 is fixed when moving to directly above the cleaning tank 19 and disengaged when moving to directly above the magnetic filter cylinder 4. Furthermore, the overall action of the transverse moving member and the magnetic scraping component ensures lateral movement, realizing the automatic magnetic scraping process during the lifting process of the lifting member.

[0040] In this invention, the magnetic rod used is a strongly magnetic rod (e.g., with a magnetic strength of 12000-13000 Gs), which can effectively adsorb iron-containing impurities. Furthermore, the bottom end of the magnetic rod has a non-magnetic section. The height of the non-magnetic section is 3cm, 5cm, 8cm, 10cm, etc. This helps reduce the difficulty of rinsing with clean water in the cleaning tank 19, improves the removal efficiency, and reduces the amount of clean water used.

[0041] like Figures 1 to 3 As shown, in some embodiments, the lifting component includes a lifting screw 13, a lifting device 15, and a lifting motor 18. The lifting device 15 is mounted on the transverse component and is connected to the lifting screw 13. The lifting device 15 is connected to the lifting motor 18, and the lifting motor 18 can control the lifting device 15, causing the lifting screw 13 to move up and down under the action of the lifting device 15. A connecting member 6 is provided at the bottom end of the lifting screw 13, which connects the lifting screw 13 to the magnetic attracting and scraping component. During operation, the lifting motor 18 drives the lifting device 15 to work, causing the lifting device 15 to rotate and drive the lifting screw 13 to move up or down, thereby driving the magnetic attracting and scraping component located at the bottom of the lifting screw 13 to move up or down, thus forming a... Figures 4 to 7 The operating principle shown is as follows: the magnetic scraping component is attracted to the magnetic filter cylinder 4. After the magnetic attraction reaches its maximum value, the lifting motor 18 starts working, driving the lifting device 15 to work, which in turn drives the lifting screw 13 to lift upwards. After the magnetic scraping component is lifted to the highest point, the lifting device stops working, and the lateral movement device starts working. Under the action of the lateral movement device, it moves to the left until it moves directly above the cleaning tank 19. Then the lateral movement device stops working, and the lifting device starts working, causing the lifting device 15 to work and causing the lifting screw 13 to move downwards, causing the magnetic scraping component to perform scraping work. When the scraping work is completed, it enters the cleaning tank 19. The lifting device stops working, and the water supply pump on the cleaning tank 19 is turned on to pump in clean water for rinsing, thus cleaning the magnetic scraping component. After cleaning is completed, the water supply pump is turned off, and the lifting device starts working again, moving in the opposite direction to send the magnetic scraping component back into the magnetic filter cylinder 4, thus achieving secondary magnetic filtration.

[0042] like Figures 1 to 3As shown, in some embodiments, the lateral movement component includes a sliding assembly and a lateral movement bracket 20 mounted on the top of the frame 1. The lateral movement bracket 20 is provided with a lateral movement screw 16, and a lateral movement motor 17 is connected to the lateral movement screw 16. The lateral movement screw 16 is connected to the sliding assembly. The lifting component is mounted on the sliding assembly, and the lateral movement motor 17 can control the lateral movement screw 16, so that the sliding assembly moves laterally on the top of the frame 1. The stability is improved by setting the transverse support 20 at the top of the frame 1; the mobility between the transverse component and the top of the frame 1 is ensured by setting a sliding component at the top of the frame 1; the transverse lead screw 16 is set on the transverse support 20, connected to the transverse motor 17, and connected to the sliding component. The transverse lead screw 16 causes the sliding component to move at the top of the frame 1. The lifting component is installed on the sliding component, so that the transverse lead screw 16 drives the sliding component to move at the top of the frame 1, thus realizing the function of the lifting component, and thus completing the movement from the top of the frame 1 to the bottom of the frame 1. Figure 5 To Figure 6 Lateral movement.

[0043] like Figures 1 to 3 As shown, in some embodiments, the sliding assembly includes a slide rail 2 disposed at the top of the frame 1, a slider 14 matched and connected to the slide rail 2, and a support platform mounted on or integrally formed with the slider 14; a lifting component is mounted on the support platform, and the slider 14 can slide freely on the slide rail 2, ensuring the smoothness of lateral movement.

[0044] like Figures 1 to 3 As shown, in some embodiments, the frame 1 is provided with a crossbar 3, and both the cleaning tank 19 and the magnetic filter cartridge 4 are mounted on the crossbar 3. The crossbar 3 is provided with several fixing seats 4.3, which are used to mount the cleaning tank 19 and the magnetic filter cartridge 4. This enhances the installation stability of the magnetic filter cartridge 4 and the cleaning tank 19.

[0045] like Figures 1 to 7As shown, in some embodiments, the magnetic filter cylinder 4 consists of two cylindrical cylinders, with a bottom seal 4.1 at the bottom of each cylinder, an inlet 4.2 near the bottom of the side wall, and an outlet 4.5 near the top of the side wall. A connecting pipe 4.4 connects the outlet 4.5 on the left cylinder to the inlet 4.2 on the right cylinder. The magnetic scraping component is located inside the cylinder and can be lifted from the top of the cylinder or inserted into it under the action of the lifting component. The cleaning tank 19 is matched with the magnetic filter cylinder 4 and can lift and move the magnetic scraping component inside the cylinder into the cleaning tank 19 for cleaning under the action of the lifting component and the lateral component. The magnetic scraping component can fit and cover the top of the cleaning tank 19 during magnetic scraping and cleaning. This helps to improve the efficiency of magnetic attraction-scraping-cleaning. In addition, in some embodiments, the magnetically attracted filter cylinder 4 is a cylindrical cylinder with three, four, five, six, seven, or eight cylinders. In operation, this specific technical solution directs the slurry to be magnetically filtered from... Figure 1 Liquid is fed into the left cylindrical cylinder through inlet 4.2, gradually filling it, and then discharged from the outlet on the left cylinder. The liquid then flows through connecting pipe 4.4 into the right cylindrical cylinder through inlet 4.5, gradually filling it, and finally discharged from outlet 4.5, thus achieving magnetic filtration. Using several cylindrical cylinders helps improve the efficiency and effectiveness of magnetic filtration.

[0046] like Figure 7 As shown, in some embodiments, the height between the top of the cleaning tank 19 and the bottom of the frame 1 is higher than the height between the magnetic filter cylinder 4 and the bottom of the frame 1, for example, 92mm higher. This ensures that when the bottom of the magnetic scraper is inserted into the cleaning tank 19 for cleaning, the bottom end of the magnetic rod can be inserted into the cleaning tank 19, improving cleaning efficiency and effectiveness.

[0047] like Figures 1 to 7 As shown, in some embodiments, the frame 1 is provided with a fixed bracket 12 and a fixed rod 11. A PCL controller 10 is installed on the fixed bracket 12 and the fixed rod 11. The PCL controller 10 is connected to the lifting component and the traversing component via electrical signals. When using the PCL controller for control to achieve automated and intelligent control, the programmable nature of the PCL controller is used for programming control. The PCL controller 10 is connected to the lifting component and the traversing component respectively, and a liquid delivery pump is set on the liquid inlet of the magnetic filter cylinder 4. At the same time, the maximum height that the lifting component can be raised or lowered directly above the magnetic filter cylinder 4 is set (e.g., the maximum height that can be raised or lowered). Figure 6The 998mm shown is the first limit position, and a first position sensor is set at the first limit position; the transverse component is set to be able to move on the frame 1 to the position shown. Figure 4 He Ru Figure 5 The rightmost position shown (e.g.) Figure 4 As shown, the second limit position is located at a distance of 536mm from the edge of the frame 1 to the lifting screw 13, and a second position sensor is installed at the second limit position; the transverse component is set to be able to move on the frame 1 to the position shown. Figure 6 He Ru Figure 7 The leftmost position shown (e.g.) Figure 6 As shown, the distance from the center line of the magnetic filter cylinder 4 to the center line of the cleaning tank 19 is 433mm, which is the third limit position, and a third position sensor is installed at the third limit position; the maximum height that the lifting component can be raised or lowered directly above the cleaning tank 19 is set as the fourth limit position, and a fourth position sensor is installed at the fourth limit position; a clean water pump is installed at the clean water pump inlet of the cleaning tank 19, and the first position sensor, second position sensor, third position sensor, fourth position sensor, clean water pump, and liquid supply pump are all electrically connected to the PCL controller 10. During operation control:

[0048] The liquid supply pump stops supplying material, and the lifting mechanism starts working, lifting the magnetic scraping component out of the magnetic filter cylinder 4. Once the lifting reaches the first limit position and simultaneously the second limit position, the first and second position sensors simultaneously input signals to the PCL controller, closing the lifting mechanism and starting the traverse mechanism. Once the traverse mechanism moves to the third limit position, the third position sensor inputs a signal to the PCL controller 10, closing the traverse mechanism and starting the lifting mechanism. This causes the magnetic scraping component to move downwards under the action of the lifting mechanism, completing the scraping process during the movement, thus removing iron particles, etc. The component is scraped to the bottom of the magnetic rod. At the same time, the lifting component descends to the fourth limit position. The fourth position sensor inputs a signal to the PCL controller to stop the lifting component. The clean water pump is turned on and pumps water into the clean water tank 19 for rinsing. After the clean water pump stops working, the lifting component is turned on to raise the magnetic suction and scraping component to the third limit position. The lifting component is turned off, and the traverse component is turned on to move the magnetic suction and scraping component to the second limit position. The traverse component is turned off, and the lifting component is turned on again, causing the magnetic suction and scraping component to descend to the first limit position. The lifting component is turned off, and the liquid supply pump is turned on to pump in the slurry to be treated.

[0049] For any other matters not covered in this invention, they can be implemented by referring to existing technology or common knowledge known to those skilled in the art, using conventional technical means. For example, a structure in which several clean water inlets are installed on the side wall of the cleaning tank 19 and a clean water pump is connected to the clean water inlets; another example is a structure in which a waste liquid pool is set at the bottom of the cleaning tank 19; yet another example is the wiring and installation when the lifting and lateral components are controlled by PCL programming.
