A guide plate type permanent magnet water treatment equipment

Abstract

This invention discloses a guide plate type permanent magnet water treatment device. The device includes a housing, a magnetic chain assembly, a decontamination mechanism, a slag recovery mechanism, and a motor drive mechanism. The key improvement, the decontamination mechanism, includes annular scraper brushes fitted along the length of each magnetic rod and guide plates that guide these brushes. In the scraping section, as the annular scraper brushes are mounted on the magnetic rods and driven by them along the magnetic chain drive direction, the guide plates above the magnetic chain change the direction of the scraper brushes, causing them to move at a certain angle to the direction perpendicular to the length of the magnetic rods. This results in a relatively linear motion of the scraper brushes along the length of the magnetic rods, thus scraping away the impurities adsorbed on the rods. This invention achieves high-efficiency decontamination by scraping impurities adsorbed on each magnetic rod from all directions, with low energy consumption and a significantly reduced overall equipment size. It is suitable for industrial wastewater treatment in fields such as steel metallurgy, machining, and mineral processing tailings.

Description

Technical Field

[0001] This invention relates to the field of industrial filtration equipment technology, and in particular to a guide plate type permanent magnet water treatment equipment. Background Technology

[0002] In industrial production processes, fluid media often contain magnetic impurities such as metal wear particles, iron oxide scale, and processing debris. These impurities can affect the normal operation of equipment, reduce product quality, and even cause equipment failure. Currently, the industrial permanent magnet water treatment equipment supplied in the domestic market is mainly cylindrical vacuum permanent magnet separators. These devices are large in size, have low magnetic filtration efficiency, and require periodic shutdowns for cleaning. While the internationally leading German SMS Group's magnetic chain filter possesses high magnetic field strength and automatic sludge removal capabilities, its scraper mechanism's periodic opening and closing prevents continuous cleaning. Its excessively large structural dimensions limit installation space and water tank capacity. The scraper arm, with its independent power source design, forms a 90° bending moment with the magnetic chain movement, easily leading to overload damage. Furthermore, its low reset accuracy and slow speed affect operational stability. These shortcomings limit its application in high-efficiency and energy-saving scenarios. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a guide plate type permanent magnet water treatment device, which controls the reciprocating motion of the annular scraper brush on the magnetic rod to scrape sludge through the guide plate. The scraping range can cover the entire length of the magnetic rod, realizing all-round, dead-angle-free sludge scraping and improving the filtration efficiency.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A guide plate type permanent magnet water treatment device includes a magnetic chain assembly, a decontamination mechanism, a slag recovery mechanism, and a motor drive mechanism. The magnetic chain assembly is characterized by being composed of multiple parallel permanent magnet rods connected by a chain to form a closed-loop ring structure. The linear velocity direction of the magnetic chain assembly is perpendicular to the length direction of the magnetic rods, and under the drive of the motor drive mechanism, it periodically reciprocates below the liquid surface of a tank used to store cold-rolling coolant. The magnetic rods are used to adsorb metal dust in the coolant. The decontamination mechanism includes guide plates and annular scraper brushes. The area directly above the magnetic chain assembly is the scraping section, and the area behind the scraping section along the transmission direction of the magnetic chain assembly is the reset section. Both the scraping section and the reset section are provided with inclined guide plates, and the inclination directions of the two guide plates are opposite. The annular scraper brush is sleeved on each of the magnetic rods and moves axially on the magnetic rods along the inclined surfaces of the two guide plates. The slag recovery mechanism is located above the liquid surface and between the magnetic rod, and is used to receive the slag scraped off by the annular slag scraper.

[0005] The beneficial effects of this invention are as follows: By designing the structure and arrangement of the decontamination mechanism, an annular scraper brush is used, with bristles arranged closely around the surface of the magnetic rod, resulting in more thorough scraping. While ensuring the decontamination rate, the annular scraper brush is detachable, which is much faster than the more complex sleeve structure and the more troublesome replacement of the sleeve. Furthermore, the use of guide plates instead of roller conveyor units simplifies the overall transmission system design, objectively resulting in energy savings. The guide plates can also be directly disassembled and replaced, facilitating maintenance.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a radially arranged longitudinal shaft is connected above the annular scraper brush, and a rolling bearing is installed on the longitudinal shaft. The outer ring of the rolling bearing makes rolling contact with the inclined surfaces of the two guide plates.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the sliding friction between the guide plate and the annular scraper brush is changed to rolling friction by using rolling bearings, which reduces the coefficient of friction and helps the annular scraper brush to effectively move and adhere to the guide plate.

[0009] Furthermore, the two guide plates are respectively set along the diagonal direction of the slag scraping section and along the diagonal direction of the reset section.

[0010] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the annular slag scraper moves from one end of the magnetic rod to the other end to scrape slag, the guide plate of the reset section is located on the diagonal of the plane where the magnetic rod is located, and it can ensure that the other end of the annular slag scraper magnetic rod moves in the opposite direction to return to the initial end for reset.

[0011] Furthermore, the guide plates at both the slag scraping section and the reset section are provided with two plates, the two guide plates at the same location are parallel to each other, and the ends of the two guide plates form openings for the rolling bearing to enter.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that the two guide plates are parallel to each other and both are perpendicular to the plane of the magnetic flux in their respective segments. The distance between the two guide plates is equal to or slightly larger than the outer diameter of the rolling bearing of the annular scraper, thereby restricting the path of the annular scraper in sequence.

[0013] Furthermore, the outer sides of the two guide plates at the same location, which are far apart from each other, are also connected to guide plate brackets, which are installed on the corresponding side walls of the housing.

[0014] The advantage of adopting the above-mentioned further solution is that the guide plate and rolling bearing are detachable, and the guide plate and rolling bearing can be easily replaced after wear.

[0015] Furthermore, four sprockets are installed on the inner sidewalls of the two ends of the magnetic flux assembly inside the box. The four sprockets are arranged in a rectangular shape, and the chain in the magnetic flux assembly is engaged with the four sprockets in a ring shape. One of the sprockets is connected to the motor transmission mechanism. The slag scraping section corresponds to the uppermost horizontal rectangular area of ​​the magnetic flux assembly, and the reset section corresponds to the vertical rectangular area of ​​the magnetic flux assembly located behind the slag scraping section.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the shape of the magnetic chain assembly is fixed by four sprockets, so that it forms a horizontally placed rectangular column structure. The rectangular planes corresponding to the slag scraping section and the reset end can enable the annular slag scraping brush on the magnetic rod to make effective contact with the guide plate.

[0017] Furthermore, the slag recycling mechanism includes a receiving hopper and a slag bin; The receiving hopper is connected between the inner walls of the box body along the length of the magnetic rod and is located above the liquid surface between the magnetic rod and the receiving hopper. The slag box is located on the outside of the box body and is in communication with the receiving hopper.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the scraped slag scraped off by the annular scraper is received by the receiving hopper and transported to the slag box, preventing the scraped slag from falling back into the box.

[0019] Furthermore, the slag recycling mechanism also includes a slag cleaning screw, which is rotatably connected to the housing along the length of the magnetic rod and located at the lowest point in the receiving hopper; one end of the slag cleaning screw is connected to the motor drive mechanism, and the other end extends into the slag box.

[0020] The beneficial effect of adopting the above-mentioned further solution is that it enables automatic recycling of scraped slag using a slag-cleaning screw, thereby improving the level of automated cleaning.

[0021] Furthermore, the motor transmission mechanism includes a drive motor, a reduction gearbox, a drive pulley, and a driven pulley; The output shaft of the drive motor is connected to the magnetic linkage assembly via a reduction gearbox. The driving pulley is fixed on the output shaft, and the driven pulley is fixed at the end of the slag cleaning screw. The driving pulley and the driven pulley are synchronously connected by a belt.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the single motor synchronously drives each mechanism, and the energy consumption of motor equipment is reduced by 40%-50%.

[0023] Furthermore, the magnetic rod is composed of a seamless steel pipe and rubidium iron discs. The rubidium iron discs are placed inside the hollow part of the seamless steel pipe and stacked one by one until it is full. The two ends of the seamless steel pipe are sealed with sealing plates.

[0024] The beneficial effects of adopting the above-mentioned further solution are that the magnetic induction intensity of the high-density neodymium iron boron permanent magnet flux linkage component reaches 15000GS, which can effectively remove 0.5-60μm magnetic particles with a magnetic particle removal rate of over 99%. The flux linkage running speed is 3-6m / min, and the water treatment efficiency reaches 2000L / min, which is twice that of traditional equipment. The iron recovery rate is increased by 4%, meeting the needs of industrial large-flow wastewater treatment. Attached Figure Description

[0028] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] according to Figures 1 to 4 As shown, this embodiment provides a guide plate type permanent magnet water treatment device, including a magnetic chain assembly, a decontamination mechanism, a slag recovery mechanism, and a motor drive mechanism. The magnetic chain assembly is characterized by being composed of multiple parallel permanent magnet rods 5 connected by a chain 4, forming a closed-loop ring structure. The linear velocity direction of the magnetic chain assembly is perpendicular to the length direction of the magnetic rods 5, and under the drive of the motor drive mechanism, it periodically reciprocates below the liquid surface of the tank 2 used to store cold-rolled cooling liquid. The magnetic rods 5 are used to adsorb metal dust in the cooling liquid.

[0030] The decontamination mechanism includes a guide plate 7 and an annular scraper brush 6. The area directly above the magnetic chain assembly is the scraping section, and the area behind the scraping section along the transmission direction of the magnetic chain assembly is the reset section. Both the scraping section and the reset section are provided with inclined guide plates 7, and the inclination directions of the two guide plates 7 are opposite. The annular scraper brush 6 is sleeved on each of the magnetic rods 5 and moves axially on the magnetic rods 5 along the inclined surfaces of the two guide plates 7. Each permanent magnet magnetic rod 5 moves perpendicular to the length direction of the magnetic rod 5 in the scraping section above the liquid surface. Under the action of the guide plate 7, the annular scraper brush 6 scrapes slag from one end of the magnetic rod 5 to the other end. During the entire movement, the magnetic rod 5 can contact the scraper brush along its entire length, and the bristles on the annular scraper brush 6 are distributed in a ring tightly against the surface of the magnetic rod 5, achieving all-round slag scraping.

[0031] The slag recovery mechanism is located above the liquid surface and between the magnetic rod 5, and is used to receive the slag scraped off by the annular slag scraper 6.

[0032] This application embodiment designs the structure and arrangement of the decontamination mechanism, employing an annular scraper brush 6 with bristles closely attached to the surface of the magnetic rod 5, resulting in more thorough scraping. While ensuring the decontamination rate, the annular scraper brush 6 is detachable, which is more convenient than a sleeve-type structure, which is more complex and cumbersome to replace. The guide plate 7 replaces the roller conveyor unit, simplifying the overall transmission system design and objectively achieving energy savings. Furthermore, the guide plate 7 can be directly disassembled and replaced, facilitating maintenance.

[0033] Specifically, wastewater containing iron slag is placed in tank 2; multiple parallel magnetic rods 5 are connected in series by chains 4 to form a ring magnetic chain. The lower part of the magnetic chain is immersed in the wastewater, and the upper part is above the water surface. Each magnetic rod 5 is fitted with a ring-shaped scraper 6 along its length. The bristles of the ring-shaped scraper 6 are spirally and tightly distributed on the inner side wall of the magnetic rod 5, so that no gaps are left during the scraping process, and impurities on the magnetic rod 5 can be scraped off to the greatest extent. Above the horizontal plane of the magnetic chain in the scraping section and the reset section, there is a guide plate 7 perpendicular to the plane; the entire magnetic chain assembly is driven by a motor transmission mechanism to rotate within the tank 2.

[0034] The section where the annular scraper brush 6 scrapes slag above the liquid surface, where the magnetic chain assembly rotates, is called the scraping section. After completing the scraping action in the scraping section, the annular scraper brush 6 returns to its initial position, which is called the reset section. Guide plates 7 are each installed above the magnetic chain assembly in both the scraping and reset sections. The guide plates 7 guide the annular scraper brush 6 from one end of the magnetic rod 5 to the other end for scraping, and after scraping, it moves in the opposite direction from the other end of the magnetic rod 5 back to its initial position for reset.

[0035] During operation, the linear velocity of the magnetic flux assembly is perpendicular to the length of the magnetic rod 5. Driven by the motor transmission mechanism, the magnetic flux assembly periodically reciprocates below the liquid surface of the tank 2 containing iron slag wastewater, thereby adsorbing magnetic particles in the cold rolling coolant. When the magnetic flux assembly rotates to the slag scraping section above the liquid surface, the annular slag scraper 6 contacts the inclined surface of the corresponding guide plate 7, and the direction of movement changes to the direction along the two guide plates 7. At this time, it moves in a straight line relative to the length of the magnetic rod 5, moving from one side of the magnetic rod 5 to the other. During this process, the magnetic particles adsorbed on the magnetic rod 5 are scraped off; the scraped magnetic particles will fall into the slag recovery mechanism set below.

[0036] Based on the above technical solution, the present invention can be further improved as follows.

[0037] Preferably, in an embodiment, a radially arranged longitudinal shaft is connected above the annular scraper brush 6, and a rolling bearing 9 is installed on the longitudinal shaft. The outer ring of the rolling bearing 9 makes rolling contact with the inclined surfaces of the two guide plates 7.

[0038] In this embodiment, the rolling bearing 9 transforms the sliding friction between the guide plate 7 and the annular scraper brush 6 into rolling friction, reducing the coefficient of friction and facilitating the effective displacement of the annular scraper brush 6 against the guide plate 7. Specifically, the annular scraper brush 6 is sleeved on the magnetic rod 5, with the bristles of the sleeve-type scraper tightly adhering to the surface of the magnetic rod 5 in a ring distribution; the rolling bearing 9 is mounted on the shaft of the annular scraper brush 6, and the axis of rotation of the rolling bearing 9 coincides with the axis of the annular scraper brush 6. When the annular scraper brush 6 enters the scraping section and the reset section, the rolling bearing 9 moves along the inclined surfaces of the two guide plates 7, and both guide plates 7 are perpendicular to the plane of the magnetic flux assembly in their respective sections.

[0039] Preferably, in the embodiment, the two guide plates 7 are respectively arranged along the diagonal direction of the slag scraping section and along the diagonal direction of the reset section. This ensures that the annular slag scraping brush 6 moves from one end of the magnetic rod 5 to the other end to scrape slag, and the guide plate 7 of the reset section is located diagonally on the plane where the magnetic rod 5 is located, and also ensures that the other end of the annular slag scraping brush 6 and the magnetic rod 5 move in the opposite direction to return to the initial end for reset.

[0040] Preferably, in the embodiment, the guide plates 7 at both the slag scraping section and the reset section are provided with two plates, the two guide plates 7 at the same location are parallel to each other, and the ends of the two guide plates 7 form openings for the rolling bearing 9 to enter.

[0041] The two guide plates 7 are parallel to each other and perpendicular to the plane of the magnetic flux in their respective segments. The distance between the two guide plates 7 is equal to or slightly larger than the outer diameter of the rolling bearing 9 of the annular scraper brush 6, thereby restricting the path of the annular scraper brush 6 in sequence.

[0042] Preferably, in the embodiment, the outer sides of the two guide plates 7 at the same location that are far apart from each other are also connected to guide plate brackets 8, and the guide plate brackets 8 are installed on the corresponding side wall of the housing 2.

[0043] The guide plate 7 is mounted on the guide plate bracket 8 and is made of stainless steel. The guide plate 7 is detachable to ensure that it can be directly replaced if damaged. The guide plate 7 is set perpendicular to or at a certain angle to the plane where the magnetic chain assembly is located. The guide plate 7 is higher than the magnetic chain to ensure that it does not come into contact with the magnetic chain, and at the same time, it can guide the annular scraper brush 6 to move in the specified direction.

[0044] Preferably, in the embodiment, four sprockets 11 are installed on the inner sidewalls of the housing 2 corresponding to both ends of the magnetic link assembly. The four sprockets 11 are arranged in a rectangular shape, and the chain 4 in the magnetic link assembly is engaged with the four sprockets 11 in a ring shape. One of the sprockets 11 is connected to the motor transmission mechanism.

[0045] The slag scraping section corresponds to the uppermost horizontal rectangular area of ​​the magnetic flux assembly, and the reset section corresponds to the vertical rectangular area of ​​the magnetic flux assembly located behind the slag scraping section.

[0046] In this embodiment, four sprockets 11 fix the shape of the magnetic chain assembly, forming a horizontally placed rectangular column structure. The rectangular planes corresponding to the scraping section and the reset end allow effective contact between the annular scraping brush 6 on the magnetic rod 5 and the guide plate 7. Specifically, according to... Figure 3 As shown, in addition, the four sprockets 11 on the two inner side walls of the housing 2 should correspond to each other in position. In order to improve the overall smoothness of the magnetic chain assembly, two sprockets 11 on the same axis are fixed together by a connecting shaft 13. That is, the eight sprockets 11 on the housing 2 form four sets of wheel-type structures. The motor transmission mechanism only needs to be connected to one of the sprockets 11 to drive the entire magnetic chain assembly to drive smoothly, which can completely avoid the problem of inconsistent linear speeds of the various sprockets 11.

[0047] Preferably, in this embodiment, the slag recovery mechanism includes a receiving hopper 12 and a slag box 14. The receiving hopper 12 is connected between the inner walls of the box body 2 along the length of the magnetic rod 5 and is located above the liquid surface between the receiving hopper 12 and the magnetic rod 5. The slag box 14 is located on the outer side of the box body 2 and communicates with the receiving hopper 12. The receiving hopper 12 receives the slag scraped off by the annular scraper brush 6 and transports it into the slag box 14 to prevent the scraped slag from falling back into the box body 2.

[0048] Preferably, in an embodiment, the slag recycling mechanism further includes a slag cleaning screw 1, which is rotatably connected to the housing 2 along the length of the magnetic rod 5 and located at the lowest point in the receiving hopper 12; one end of the slag cleaning screw 1 is connected to the motor drive mechanism, and the other end extends into the slag box 14.

[0049] This embodiment utilizes a slag-cleaning screw 1 to achieve automatic slag recovery, improving the level of automated cleaning. When the magnetic chain assembly rotates to the upper part of the housing 2, the annular slag-cleaning brush 6 moves along the length of the magnetic rod 5 under the action of the guide plate 7, scraping off the iron slag adsorbed on the magnetic rod 5 through the internal bristles; the iron slag falls into the receiving hopper 12 below, and the slag-cleaning screw 1 is set at the lowest point of the bottom of the receiving hopper 12. The accumulated iron slag is pushed into the slag box 14 set on the outside of the housing 2 and connected to the receiving hopper 12 by the slag-cleaning screw 1.

[0050] Preferably, in an embodiment, the motor transmission mechanism includes a drive motor 17, a reduction gearbox 16, a drive pulley 15, and a driven pulley 19.

[0051] The output shaft 3 of the drive motor 17 is connected to the magnetic linkage assembly via a reduction gearbox 16. The driving pulley 15 is fixed on the output shaft 3, and the driven pulley 19 is fixed at the end of the slag cleaning screw 1. The driving pulley 15 and the driven pulley 19 are synchronously connected via a belt 18.

[0052] This embodiment of the application uses a single motor to synchronously drive each mechanism, reducing energy consumption by 40%-50% compared to other motor-driven equipment. Specifically, because the drive motor 17 rotates too fast, a reduction gearbox 16 is connected to reduce the speed to a suitable level. The output end of the reduction gearbox 16 is connected to the output shaft 3, and a drive pulley 15 is installed on the output shaft 3. The drive pulley 15 is interconnected with the driven pulley 19 via a belt 18. The driven pulley 19 is located at one end of the cleaning screw 1, and its rotation transmits power to the cleaning screw 1 to clean the slag from the receiving hopper 12. This power transmission method reduces the number of drive motors 17 and fully utilizes their energy efficiency.

[0053] Preferably, in the embodiment, the magnetic rod 5 is composed of a seamless steel pipe and a rubidium iron disc, the rubidium iron disc is placed in the hollow part inside the seamless steel pipe, and the discs are stacked one by one until the pipe is filled, and the two ends of the seamless steel pipe are sealed with sealing plates.

[0054] The high-density neodymium iron boron permanent magnet flux linkage component has a magnetic induction intensity of 15000GS, which can effectively remove 0.5-60μm magnetic particles with a magnetic particle removal rate of over 99%. The flux linkage runs at a speed of 3-6m / min, and the water treatment efficiency reaches 2000L / min, which is twice that of traditional equipment. The iron recovery rate is increased by 4%, meeting the needs of large-flow industrial wastewater treatment.
