Description

Technical Field

[0001] This invention relates to the field of filter cleaning technology, and in particular to a magnetic filter degreasing device. Background Technology

[0002] Emulsions are used in the steel rolling process. When the emulsion is in use, oil and water separate. The oil adheres to the steel surface to form an oil film, which reduces the friction between the steel and the rolls. The water absorbs the heat from the steel and evaporates, carrying away the heat from the steel surface. Therefore, after the emulsion is used, there will be a certain amount of iron powder or fine iron slag. These iron powders and slags need to be filtered using a magnetic filter before the emulsion can be reused.

[0003] A magnetic filter is a precision filtration device for emulsions. It can adsorb iron powder and slag in the used emulsion onto the surface of the magnetic filter, separating the iron powder and slag from the emulsion, so that the emulsion can be reused.

[0004] However, due to oil-water separation during the use of the emulsion, a certain amount of oil adheres to these iron powders and slags, causing them to become sticky and turn into sludge. Therefore, when cleaning the magnetic filter, this sludge will stick to the hanging plate and will not easily fall into the screw conveyor below the scraper. In actual operation, some sludge still remains on the magnetic filter after scraper cleaning, resulting in poor scraper cleaning effect. Summary of the Invention

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Reference Figures 1 to 8 As shown, a magnetic filter desludge removal device of the present invention includes a first mounting plate 11 and a second mounting plate 12; a plurality of magnetic filters 13 are fixedly connected between the first mounting plate 11 and the second mounting plate 12; a forward and reverse motor 2 is fixedly connected to the outer side of the first mounting plate 11; a transmission assembly 3 is fixedly connected to the output shaft of the forward and reverse motor 2; a drive assembly 4 is rotatably connected between the first mounting plate 11 and the second mounting plate 12; the drive assembly 4 is fixedly connected to the transmission assembly 3; the transmission assembly 3 is used to drive the drive assembly 4 to rotate; a movable slide rail 5 is threadedly connected to the drive assembly 4; a scraper 6 is slidably connected to the movable slide rail 5; the scraper 6 is in contact with the surface of the magnetic filter 13 and is arranged in a rake-like manner; the scraper 6 is used to remove the sludge on the magnetic filter 13; a blowing assembly 7 is provided above both the first mounting plate 11 and the second mounting plate 12; the blowing assembly 7 is used to remove the sludge on the scraper 6.

[0031] To ensure that the scraper 6 can more thoroughly clean the sludge on the surface of the magnetic filter 13 and improve its cleaning efficiency, the scraper 6 is designed in a rake shape. This increases the contact area between the scraper 6 and the magnetic filter 13, and the length of the scraper 6 can span 2 to 4 magnetic filters 13 at a time, cleaning multiple magnetic filters 13 simultaneously. The appropriate length can be selected based on actual conditions and requirements. When cleaning the oil stains on the magnetic filter 13, the forward and reverse motor 2 is started, driving the transmission component 3 to rotate. The transmission component 3 drives the fixed connection... The drive assembly 4 rotates, causing the moving slide rail 5 to move horizontally along the axis of the magnetic filter 13. The moving slide rail 5 drives the scraper 6 to move, removing the sludge from the surface of the magnetic filter 13. The blowing assembly 7 is in the normally open state. When the scraper 6 scrapes off the sludge from the surface of the magnetic filter 13 and moves to one end of the magnetic filter 13, the blowing assembly 7 blows off the sludge on the scraper 6 and the sludge at the end of the magnetic filter 13, solving the problems that the sludge is not easy to fall off the scraper 6 and that the scraper 6 has a poor cleaning effect on the magnetic filter 13.

[0032] Please refer to Figure 1 and Figure 2 As shown, the transmission assembly 3 includes a first pulley 31 and a second pulley 32; the first pulley 31 has a double belt groove and is fixedly connected to the output shaft of the forward and reverse motor 2; two second pulleys 32 are provided, and the two second pulleys 32 are fixedly connected to the drive assembly 4; the first pulley 31 and the second pulley 32 are connected by a belt.

[0033] In order to enable the drive assembly 4 to rotate in one direction, a second pulley 32 is fixedly connected to the drive assembly 4, and the first pulley 31 is driven to rotate by the forward and reverse motor 2, so that the first pulley 31 drives the two second pulleys 32 to rotate synchronously and keep rotating in the same direction through the belt.

[0034] Please refer to Figure 2 and Figure 3 As shown, the drive assembly 4 includes a lead screw 41; the lead screw 41 is rotatably connected between the first mounting plate 11 and the second mounting plate 12; two lead screws 41 are provided; the two lead screws 41 are located on both sides of the magnetic filter 13; the lead screw 41 is threadedly connected to the movable slide rail 5; the lead screw 41 is used to drive the movable slide rail 5 to move; a guide rod 42 is fixedly connected directly below the lead screw 41; the guide rod 42 is slidably connected to the movable slide rail 5; the guide rod 42 is used to guide the movable slide rail 5 and restrict the rotation of the movable slide rail 5; both the lead screw 41 and the guide rod 42 are parallel to the magnetic filter 13.

[0035] In order to enable the movable slide rail 5 to move along the axial direction of the magnetic filter 13, so that the scraper 6 on the movable slide rail 5 can scrape the sludge on the magnetic filter 13 cleanly, a lead screw 41 is provided. When the forward and reverse motor 2 drives the first pulley 31 and the second pulley 32 to rotate, the two lead screws 41 rotate in the same direction. Under the action of the thread of the lead screw 41 and the guide rod 42, the movable slide rail 5 is driven to move horizontally along the guide rod 42 seat. By providing two lead screws 41 and guide rods 42, the movable slide rail 5 will not rotate or deviate during movement, thus ensuring the stability of the movable slide rail 5 during movement.

[0036] Please refer to Figure 3 , Figure 6 and Figure 7 As shown, the movable slide rail 5 includes a vertical plate 51 and a horizontal plate 52; two vertical plates 51 are provided; the lower end of the vertical plate 51 is threadedly connected to the lead screw 41 and slidably connected to the guide rod 42; a first straight groove 511 is formed at the upper end of the vertical plate 51; a spring 512 is fixedly connected to the inner bottom of the first straight groove 511; the spring 512 is used to tighten the horizontal plate 52; the horizontal plate 52 is slidably connected inside the first straight groove 511 and fixedly connected to the spring 512; a second straight groove 521 is formed in the middle of the horizontal plate 52; the scraper 6 is slidably connected to the second straight groove 521;

[0037] In practice, to completely remove iron powder and slag from the emulsion, multiple magnetic filters 13 need to be arranged side-by-side and connected end-to-end. This allows the iron powder and slag in the emulsion to be adsorbed and separated from the emulsion by the magnetic filters. This results in the width of the magnetic filters 13 being greater than the width of the scraper 6. If the width of the scraper 6 is increased, the friction between the scraper 6 and the magnetic filters 13 becomes too great, making it difficult for the scraper 6 to move and remove the sludge from the magnetic filters 13. Therefore, by moving the scraper 6 along the direction of the magnetic filters 13 and repeatedly scraping the sludge off the magnetic filters 13, the sludge on all magnetic filters 13 is removed. During operation, the vertical plate 51, under the action of the lead screw 41... The horizontal plate 52 moves horizontally along the guide rod 42, causing the horizontal plate 52 to drive the scraper 6 to move horizontally in the axial direction of the magnetic filter 13, thereby scraping off the sludge on the magnetic filter 13. At the same time, under the action of the spring 512, the horizontal plate 52 is always pressed down, so that the scraper 6 is always in contact with the magnetic filter 13, improving the efficiency of the scraper 6 in scraping off the sludge on the magnetic filter 13. When the horizontal plate 52 drives the scraper 6 to move to one end of the magnetic filter 13, the scraper 6 moves along the direction of the magnetic filter 13 arrangement, so that the scraper 6 comes into contact with other magnetic filters 13 that have not been scraped off sludge. The vertical plate 51 is driven to move by the lead screw 41, and the horizontal plate 52 drives the scraper 6 to scrape off the magnetic filters 13 that have not been scraped off sludge.

[0038] Please refer to Figure 1 , Figure 4 and Figure 5 As shown, a movable component 8 is fixedly connected to the upper end of the second mounting plate 12; the movable component 8 includes a slide 81; a connecting plate 82 is fixedly connected to one side of the slide 81; an electric push rod 83 is fixedly connected to the connecting plate 82; the telescopic shaft of the electric push rod 83 passes through the connecting plate 82; the electric push rod 83 is used to push the scraper 6 to move within the slide groove 84; a slide groove 84 is provided above the slide 81; a first baffle 85 is fixedly connected to the outer side of the slide 81; and first inclined surfaces 8 are provided at the top of both ends of the slide 81. 6. A second inclined surface 87; the first inclined surface 86 is used for the upward movement of the scraper 6; a straight plate 61 is fixedly connected to the upper end of the scraper 6; a changeover switch 62 is fixedly connected to the end of the straight plate 61 facing the first mounting plate 11; a start switch 63 and a stop switch 64 are fixedly connected to the end of the straight plate 61 facing the second mounting plate 12; a second baffle 88 is fixedly connected to the top of the first mounting plate 11; the stop switch 64 and the changeover switch 62 are electrically connected to the forward and reverse motor 2; the start switch 63 is electrically connected to the electric push rod 83.

[0039] To enhance the sludge removal effect of the scraper 6 on the magnetic filter 13 and to clean multiple magnetic filters 13, a moving assembly 8 is provided on the second mounting plate 12. When the scraper 6 is pushed by the horizontal plate 52 from its initial position near the second mounting plate 12 and moves along the guide rod 42 towards the first mounting plate 11, the scraper 6 scrapes away the sludge from the magnetic filter 13. As the scraper 6 gradually approaches the first mounting plate 11, the changeover switch 62 on the straight plate 61 abuts against the second baffle 88, causing the forward / reverse motor 2 to reverse, thereby causing the lead screw 41 to reverse. This causes the vertical plate 51 to pull the horizontal plate 52, pulling the scraper 6 back, allowing the scraper 6 to perform a secondary scraping of the magnetic filter 13, increasing the cleaning effect of the scraper 6 on the magnetic filter 13. As the scraper 6 is pulled back and gradually approaches the second mounting plate 12, the straight plate 61 contacts the slide table 81 and moves upward along the first inclined surface 86. The spring 512 stretches, generating tension. At this time, the scraper 6 separates from the magnetic filter 13. The scraper 6 is inserted into the slide groove 84 and contacts the first baffle 85, causing the stop switch 64 and start switch 63 to abut against the first baffle 85. At this time, the forward and reverse motor 2 stops, the electric push rod 83 starts, and the telescopic shaft of the electric push rod 83 extends to push the straight plate 61 to move, so that the scraper 6 moves in the direction of the magnetic filter 13. When the electric push rod 83 pushes the straight plate 61 to the other end of the slide table 81, under the action of gravity and the tension of the spring 512, the scraper 6 moves down from the second inclined surface 87 and contacts the magnetic filter 13 that has not been scraped of sludge. At this time, the stop switch 64 and start switch 63 separate from the first baffle 85, the forward and reverse motor 2 restarts and rotates forward, driving the lead screw 41 to rotate, thereby driving the vertical plate 51 to push the horizontal plate 52 to move, so that the scraper 6 scrapes the sludge on the magnetic filter 13. If the scraper 6 cannot cover all the magnetic filters 13 in one movement, multiple sets of moving components 8 can be set up to repeat the above process.

[0040] Please refer to Figure 1 and Figure 8 As shown, both the first mounting plate 11 and the second mounting plate 12 have connection holes 14 at their upper ends; the connection holes 14 are used to insert the cover plate 9; a support rod 91 is fixedly connected to the bottom of the cover plate 9; the support rod 91 is inserted into the connection hole 14; the cover plate 9 is fixedly connected to the purging assembly 7; the purging assembly 7 includes an air pipe 71; the air pipe 71 is fixedly connected to the cover plate 9; an energy-saving 973 model nozzle 72 is fixedly connected to the outlet of the air pipe 71.

[0041] In order to remove the sludge on the scraper 6, if other cleaning devices are added to clean the sludge on the scraper 6, the sludge will still stick to the cleaning components due to its stickiness. Therefore, a blowing component 7 is set above the scraper 6. Compressed air is delivered to the energy-saving 973 model nozzle 72 through the air pipe 71. The compressed air is blown onto the scraper 6 through the nozzle 72, thereby cleaning the sludge on the scraper 6. At the same time, the compressed air sprayed from the nozzle 72 can also blow away the sludge at both ends of the magnetic filter 13. In addition, the cover plate 9 can prevent large foreign objects from falling into the emulsion and can also protect the safety of the workers.

[0042] Please refer to Figure 1 and Figure 2 As shown, the bottom of the first mounting plate 11 and the second mounting plate 12 are provided with trapezoidal grooves 15; a collection groove 10 is inserted into the trapezoidal groove 15; the collection groove 10 is conical and has a discharge port 101 at the bottom.

[0043] In order to guide the sludge blown off the scraper 6 by the purging assembly 7 into the screw conveyor below and carry the sludge out, a collection trough 10 is provided below the magnetic filter 13. The sludge blown off the scraper 6 by the nozzle 72 falls into the collection trough 10. Due to the conical sidewall of the collection trough 10, the sludge flows towards the discharge port 101 and enters the screw conveyor through the discharge port 101 to be carried out.

[0044] Working principle: When the scraper 6 contacts the magnetic filter 13, the forward and reverse motor 2 is started. The forward and reverse motor 2 drives the lead screw 41 to rotate through the first pulley 31 and the second pulley 32. The lead screw 41 drives the vertical plate 51 to push the horizontal plate 52 to move, so that the scraper 6 on the horizontal plate 52 scrapes the sludge off the magnetic filter 13. The blowing assembly 7 is in the normally open state. When the scraper 6 moves to one end of the magnetic filter 13, the nozzle 72 blows off the sludge on the scraper 6. At the same time, the changeover switch 62 of the straight plate 61 at the upper end of the scraper 6 connects with the second... When the baffle 88 contacts the motor, it changes the direction of the forward and reverse motor 2. The lead screw 41 reverses, causing the vertical plate 51 to pull back and the scraper 6 to be pulled back through the horizontal plate 52. When the scraper 6 moves to the other end, the stop switch 64 and start switch 63 on the other side of the straight plate 61 are activated, and the electric push rod 83 is started, moving the scraper 6 a distance along the direction of the magnetic filter 13 so that the scraper 6 contacts the magnetic filter 13 that has not been scraped of sludge. The above process is repeated to scrape off the sludge on all the magnetic filters 13.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
