Description

Technical Field

[0001] The invention relates to the technical field of iron powder cleaning, in particular to an iron slag lapping powder cleaning device. Background Art

[0002] Iron slag grinding powder is a micron-sized powder produced by crushing and grinding waste generated during the production of metallurgy, casting and electronic soft magnetic materials. Its main component is iron-based magnetic material, and it also contains impurities such as oil, oxides, non-magnetic metal particles and organic binders. The efficient recovery and reuse of this powder is a key link in the circular economy. Therefore, it is necessary to remove impurities through a cleaning process to improve material performance and meet recycling requirements.

[0003] At present, ultrasonic cleaning technology is widely used in the industry to treat iron slag grinding powder. This technology uses the cavitation effect of high-frequency ultrasound to impact the powder surface through micro-jets to effectively remove loose contaminants. However, the cleaning effect of ultrasonic cleaning on iron powder is limited to loose surface contaminants and cannot deeply deal with internal inclusions or stubborn stains.

[0004] Ultrasonic waves rely on the cavitation effect, which limits their cleaning effect. They cannot remove stubborn impurities (such as grinding medium debris, oxide layers, etc.) embedded in the gaps between iron powders through physical contact cleaning. In addition, micron-sized iron powders will form agglomerates due to van der Waals forces and electrostatic forces, resulting in the ultrasonic cavitation effect acting only on the surface of the agglomerates. The internal particles cannot contact the cleaning liquid, forming a cleaning blind spot.

[0005] In addition, the cleaning liquid is in a weak circulation state in the ultrasonic cleaning tank and cannot impact the gaps between the iron powders through strong directional water flow. It lacks the function of active flushing and is therefore unable to break up the iron powder agglomerates. Moreover, the debris cleaned from the iron powder by the cleaning liquid tends to adhere to the iron powder again, weakening the cleaning effect. Summary of the Invention

[0020] 2. The present invention uses the reciprocating motion of the material gathering baffle in the flushing mechanism to drive the iron powder to move rapidly in the cleaning liquid, so that the iron powder and the cleaning liquid form a high-speed relative movement, so that the water flow forms a high-intensity impact on the iron powder, which can break up the iron powder agglomerates, eliminate the cleaning blind spots, and increase the cleaning effect.

[0021] 3. The present invention adopts a driving component to synchronously drive the magnetic plate to move back and forth rapidly left and right, and cooperates with the rapid up and down reciprocating movement of the gathering baffle, which increases the direction of directional flushing and improves the flushing effect. At the same time, it can stir the cleaning liquid to prevent the iron powder in the cleaning liquid from settling, increase the distribution uniformity of the iron powder in the cleaning liquid, and thus ensure the flushing effect of the iron powder.

[0022] Fourth, the present invention adopts a material gathering baffle that can automatically adjust its position during the up and down movement, which optimizes the pushing effect of the material gathering baffle on the iron powder in the cleaning liquid, ensures that the iron powder in the cleaning liquid can be efficiently and fully flushed, and further increases the flushing effect.

DETAILED DESCRIPTION

[0037] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0038] See Figure 1 、 Figure 2 and Figure 3 A device for cleaning iron slag grinding powder comprises a water tank 1 for ultrasonic cleaning, a scrubbing mechanism 2 for cleaning iron powder by physical contact rubbing is provided inside the water tank 1, and a flushing mechanism 3 for pushing the iron powder to impact with water flow, thereby flushing the iron powder, is provided inside the water tank 1 and on the left side of the scrubbing mechanism 2.

[0039] When the iron slag grinding powder needs to be cleaned, the operator adds the iron slag grinding powder to the water tank 1. The cleaning liquid in the water tank 1 drives the iron powder to move from left to right. At the same time, the iron powder in the cleaning liquid is ultrasonically cleaned by the existing ultrasonic cleaning equipment. It should be noted that the appropriate length of the water tank 1 can be selected according to actual needs.

[0040] When the water flow drives the iron powder to flow to the position of the flushing mechanism 3, the flushing mechanism 3 pushes the iron powder in the water flow to impact the water flow at high speed through continuous reciprocating movement in the up and down directions, thereby flushing the iron powder in the water flow and breaking up the iron powder that has agglomerated together. Then the water flow drives the iron powder to flow to the position of the scrubbing mechanism 2, and the iron powder is gathered and retained by the scrubbing mechanism 2. At the same time, the scrubbing mechanism 2 performs contact reciprocating scrubbing on the retained iron powder in the up and down directions, thereby further cleaning the iron powder. In the process of scrubbing the iron powder, the flushing mechanism 3 can also drive the scrubbing mechanism 2 to perform reciprocating flushing on the iron powder left and right, thereby further increasing the cleaning effect.

[0041] See Figure 2 、 Figure 3 and Figure 6 The scrubbing mechanism 2 includes a sliding frame 21 that slides left and right inside the water tank 1, and a linkage assembly 22 is provided inside the sliding frame 21. The linkage assembly 22 includes guide grid plates 221 that are arranged at equal intervals along the front and rear directions and rotatably arranged inside the sliding frame 21. A magnetic plate 23 is fixedly connected to the center position of the guide grid plate 221, and a shaking plate 222 is fixedly installed on the upper side of the guide grid plate 221. A synchronization plate 223 is hinged to all the shaking plates 222.

[0042] See Figure 2 、 Figure 3 and Figure 4 The flushing mechanism 3 includes a fixed frame 31 fixedly installed inside the water tank 1 and located on the left side of the sliding frame 21. The fixed frame 31 is connected to two groups of material gathering baffles 33 arranged upper and lower through a driving component 32. Each group consists of two material gathering baffles 33 that can automatically change the material gathering position according to the moving direction.

[0043] See Figure 3 、 Figure 4 and Figure 5 The driving assembly 32 includes two reciprocating plates 321 symmetrically arranged front and back and sliding up and down on the fixed frame 31. The material gathering baffle 33 rotates together between the two reciprocating plates 321. A rocker plate 322 is fixedly installed on the rear side of the material gathering baffle 33. The two rocker plates 322 on the same vertical plane are hinged together with a vertical connecting plate 323.

[0044] Continue reading Figure 3 、 Figure 4 and Figure 5 A driving motor 324 is fixedly installed on the upper side of the fixed frame 31, and an active circular plate 325 is fixedly installed on the output shaft of the driving motor 324. A U-shaped plate 326 is provided on the fixed frame 31 for sliding in the vertical direction. The eccentric position of the active circular plate 325 is hinged to the horizontal section of the U-shaped plate 326 through a push-pull plate 327, and the rear side of the U-shaped plate 326 is hinged to the two upper crank plates 322 through a hinged connecting plate 329.

[0045] When the iron powder needs to be cleaned, the drive motor 324 is started, and the drive motor 324 drives the active circular plate 325 to rotate. The active circular plate 325 pushes and pulls the U-shaped plate 326 up and down through the push-pull plate 327. When the U-shaped plate 326 moves downward, the U-shaped plate 326 pushes the two upper rocker plates 322 downward to rotate through the hinged connecting plate 329. The two upper rocker plates 322 respectively drive the two lower rocker plates 322 to rotate synchronously through the vertical connecting plate 323, so that the rocker plates 322 drive the upper parts of the two material gathering baffles 33 in the same horizontal plane to be combined together.

[0046] When the U-shaped plate 326 moves downward, the two material gathering baffles 33 in the same horizontal plane are combined into an inverted V-shaped structure. Then the U-shaped plate 326 drives the material gathering baffle 33 to move downward quickly by pushing the rocker plate 322 downward. The two material gathering baffles 33 combined into the inverted V-shaped structure collect the iron powder in the water flow through the inside of the inverted V-shaped structure and drive the iron powder to move downward quickly, so that the iron powder impacts the water flow, and then flushes the iron powder, thereby increasing the cleaning effect and breaking up the agglomerated iron powder through the impact.

[0047] At the same time, the material gathering baffle 33 that moves back and forth up and down can also stir the iron powder in the water back and forth, thereby preventing the iron powder from settling.

[0048] When the U-shaped plate 326 moves upward, the principle is the same as above, so that the two material gathering baffles 33 in the same horizontal plane are combined into a V-shaped structure, thereby continuously flushing the iron powder to ensure cleaning efficiency.

[0049] In the initial state, the guide grid plate 221 drives the magnetic plate 23 to tilt toward one side, and all the shaking plates 222 rotate synchronously through the connection of the synchronization plate 223, so that all the guide grid plates 221 are always parallel to each other, so that all the magnetic plates 23 are synchronously tilted toward one side, and then the arrangement direction of the magnetic plate 23 is at an angle to the direction of water flow. The water flow drives the iron powder inside it to impact the guide grid plate 221 and flow along the arrangement direction of the guide grid plate 221.

[0050] When the water flow drives the iron powder inside to flow to the position of the magnetic plate 23, the magnetic plate 23 adsorbs the iron powder in the water flow on its side facing the direction of the water flow through its own magnetic force.

[0051] See Figure 3 、 Figure 6 and Figure 7A shift frame 28 is provided inside the water tank 1 and is located on the right side of the sliding frame 21 for sliding left and right. A cleaning plate 25 for kneading the iron powder on the magnetic plate 23 is provided on the shift frame 28 through a connecting component 24. The connecting component 24 includes flip plates 241 that are arranged at equal intervals along the front and rear directions and movably inserted into the shift frame 28. The flip plates 241 correspond to the magnetic plates 23 one by one and are arranged parallel to them. The flip plate 241 is connected to the cleaning plate 25 at the corresponding position through a connecting rod structure 242 arranged on its left side.

[0052] In this embodiment, polypropylene bristles for scrubbing iron powder are provided on the left side of the cleaning plate 25 .

[0053] See Figure 7 The connecting rod structure 242 includes a telescopic rod 243 arranged in a rectangular shape and hinged between the flip plate 241 and the cleaning plate 25. The left parts of the two telescopic rods 243 on the same horizontal plane are hinged with a connecting rod 244, so that the left parts of the two telescopic rods 243 on the same horizontal plane, the connecting rod 244, and the cleaning plate 25 form a parallelogram structure.

[0054] See Figure 3 、 Figure 6 and Figure 7 A plurality of swing plates 26 corresponding to the flip plates 241 are rotatably provided on the shift frame 28. The swing plates 26 are slidably connected to the flip plates 241 at the corresponding positions. A linkage plate 261 is hinged on all the swing plates 26. A servo motor 262 for driving the guide grid plate 221 to rotate is fixedly installed on the upper part of the sliding frame 21. An electric cylinder 263 connected to the sliding frame 21 is fixedly installed on the right side of the shift frame 28.

[0055] It should be noted that the output shaft of the servo motor 262 in this embodiment is fixedly connected to the upper side surface of the frontmost guide grid plate 221.

[0056] The linkage plate 261 can drive all the flip plates 241 to rotate synchronously through the swing plate 26. Since the left parts of the two telescopic rods 243, the connecting rod 244, and the cleaning plate 25 on the same horizontal plane form a parallelogram structure, the flip plates 241 and the cleaning plates 25 are connected by sliding left and right, so that the flip plates 241 and the cleaning plates 25 are always arranged in parallel.

[0057] After the magnetic plate 23 has adsorbed the iron powder for a fixed time, the servo motor 262 is started to drive the guide grid 221 to flip, so that the guide grid 221 is arranged symmetrically with its original posture, and the guide grid 221 drives the magnetic plate 23 to flip until the iron powder adsorbed on the magnetic plate 23 rotates to the right, thereby continuing to adsorb the iron powder in the water flow by rotating the magnetic plate 23 to the left side, so that the scrubbing and adsorption processes are carried out simultaneously.

[0058] See Figure 7 and Figure 8 The center position of the flip plate 241 is hinged with a sliding rod 245, and the center position of the cleaning plate 25 is hinged with a sliding sleeve 246 that is slidingly connected to the corresponding sliding rod 245. A pre-tightening plate 247 is provided inside the sliding rod 245 for sliding along its axial direction. An adjusting screw 248 that is rotatably connected to the pre-tightening plate 247 is threaded on the sliding rod 245, and a constant force spring is provided between the pre-tightening plate 247 and the sliding sleeve 246.

[0059] In the initial state, the telescopic section of the electric cylinder 263 is in an extended state, so that the shift frame 28 is located away from the sliding frame 21, the constant force spring is in a fully extended state, and the constant force spring drives the cleaning plate 25 to be away from the flip plate 241 by pushing the sliding sleeve 246.

[0060] When the magnetic plate 23 drives the iron powder adsorbed on its side to rotate toward the cleaning plate 25, the telescopic section of the electric cylinder 263 contracts to drive the shift frame 28 to move toward the sliding frame 21. The sliding frame 21 drives the cleaning plate 25 to lean against the side of the magnetic plate 23 facing the cleaning plate 25, and the reaction force of the magnetic plate 23 on the cleaning plate 25 compresses the constant force spring. At the same time, the magnetic plate 23 pushes the cleaning plate 25 to rotate until it is arranged parallel to the magnetic plate 23.

[0061] When the cleaning plate 25 scrubs the iron powder on the magnetic plate 23, it will rub the iron powder on the magnetic plate 23 into the water flow, so that the iron powder on the magnetic plate 23 gradually decreases with the scrubbing process. During this process, the constant force spring can push the cleaning plate 25 through its own elastic force to always be able to contact the magnetic plate 23 with a certain resistance force, thereby ensuring the cleaning effect of the iron powder on the magnetic plate 23.

[0062] The operator can adjust the position of the pre-tightening plate 247 inside the sliding rod 245 by pre-rotating the adjusting screw 248. The pre-tightening plate 247 can change the distance between the cleaning plate 25 and the shift frame 28 in the initial state through the constant force spring and the sliding sleeve 246, so that after the shift frame 28 moves to a fixed position close to the sliding frame 21, the magnetic plate 23 pushes the constant force spring to a different degree of compression, thereby changing the pressing force of the cleaning plate 25 on the magnetic plate 23 to adapt to the different sizes of iron powder to exert different kneading forces.

[0063] See Figure 3 、 Figure 6 and Figure 11The eccentric position of the active circular plate 325 is hinged to the sliding frame 21 through a linkage hinge plate 328. Two bracket plates 27 symmetrically arranged front and back are fixedly installed on the upper side of the fixed frame 31. The bracket plate 27 is connected to the sliding frame 21 and the shift frame 28 for left and right sliding. A track slot plate 271 is fixedly installed on the right part of the upper side of the bracket plate 27. A lifting plate 272 is provided on the upper part of the flip plate 241 for joint rotation. A fixed pillar 273 sliding inside the corresponding track slot plate 271 is fixedly installed on the lower part of the lifting plate 272.

[0064] In this embodiment, a guide groove is formed on the track groove plate 271 , and the left side of the guide groove is higher than the right side thereof. The fixed pillars 273 slide in the guide grooves of the track groove plate 271 at corresponding positions.

[0065] When the active circular plate 325 rotates, the active circular plate 325 drives the sliding frame 21 to move back and forth left and right through the linkage hinge plate 328, and the sliding frame 21 drives the shift frame 28 to move synchronously through the electric cylinder 263. When the shift frame 28 moves to the left, the shift frame 28 drives the lifting plate 272 and the fixed support 273 to move synchronously to the left through the flip plate 241, so that the track groove plate 271 drives the flip plate 241 to move upward by pushing the fixed support 273 upward, and the flip plate 241 drives the cleaning plate 25 to move upward relative to the magnetic plate 23, so that the cleaning plate 25 scrubs the iron powder on the magnetic plate 23.

[0066] When the cleaning plate 25 scrubs the iron powder on the right side of the magnetic plate 23, the left side of the magnetic plate 23 simultaneously absorbs and collects the iron powder in the water flow. In the process of the active circular plate 325 driving the gathering baffle 33 to flush the iron powder up and down, the active circular plate 325 also drives the magnetic plate 23 to move left and right, thereby flushing the iron powder on it in the left and right directions.

[0067] See Figure 7 、 Figure 9 and Figure 10 A plurality of scraping plates 251 sliding along the thickness direction of the cleaning plate 25 are arranged at equal intervals in the vertical direction on the cleaning plate 25. The scraping plates 251 are arranged obliquely. A water blocking plate 252 is fixedly installed on the right side of each two scraping plates 251. Combing grooves 253 extending through the thickness direction of the scraping plates 251 are provided at equal intervals along the oblique direction on the left side of the scraping plates 251. The combing grooves 253 on two adjacent scraping plates 251 are arranged alternately.

[0068] When the cleaning plate 25 moves to the left, the cleaning plate 25 drives the scraper plate 251 and the water blocking plate 252 thereon to move synchronously, and the water blocking plate 252 is pushed to the right by the resistance of the water flow to the water blocking plate 252, so that the water blocking plate 252 is located away from the cleaning plate 25, so that the water blocking plate 252 drives the left side of the scraper plate 251 to be located inside the cleaning plate 25.

[0069] When the active circular plate 325 drives the cleaning plate 25 and the magnetic plate 23 to move to the right, the track slot plate 271 drives the cleaning plate 25 to move downward relative to the magnetic plate 23, thereby continuously scrubbing the iron powder on the magnetic plate 23. At the same time, the resistance of the water flow to the water blocking plate 252 pushes it to the left, so that the water blocking plate 252 drives the left side of the scraper plate 251 to rest against the magnetic plate 23, so that the magnetic plate 23 drives the scraper plate 251 to scrape the iron powder on the magnetic plate 23 downward.

[0070] By scraping the iron powder while scrubbing downwards, the thickness of the iron powder on the magnetic plate 23 can be gradually reduced, and the iron powder can be scraped into the cleaning liquid again to prevent the iron powder from continuing to accumulate on the magnetic plate 23. When the scraper plate 251 scrapes the iron powder downwards, the iron powder can be combed through the combing grooves 253 thereon. Through the combing grooves 253 arranged alternately on the two adjacent scraper plates 251, the iron powder can be moved back and forth along the width direction of the magnetic plate 23 to turn over, so that the cleaning plate 25 is in full contact with the iron powder on the magnetic plate 23, ensuring the scrubbing effect.

[0071] When cleaning iron powder, the present invention also includes the following steps: the first step is to start the drive motor 324 to drive the material gathering baffle 33 to move back and forth up and down, so that the material gathering baffle 33 is combined together to gather the iron powder in the water flow and drive the iron powder to move downward quickly, thereby causing the iron powder to impact the water flow and increase the cleaning effect.

[0072] In the second step, the magnetic plate 23 uses its own magnetic force to adsorb the iron powder in the water flow on the side of the magnetic plate 23 facing the water flow. After a fixed time, the servo motor 262 is started to drive the magnetic plate 23 to flip until the iron powder adsorbed on the magnetic plate 23 rotates to the right, thereby continuing to adsorb the iron powder in the water flow by rotating the magnetic plate 23 to the side facing the left.

[0073] In the third step, the telescopic section of the electric cylinder 263 contracts to drive the shift frame 28 to move toward the sliding frame 21, so that the constant force spring pushes the cleaning plate 25 against the side of the magnetic plate 23 facing the cleaning plate 25 through its own elastic force, and at the same time, the magnetic plate 23 pushes the cleaning plate 25 to rotate until it is arranged parallel to the magnetic plate 23.

[0074] In the fourth step, the active circular plate 325 drives the cleaning plate 25 to move back and forth relative to the magnetic plate 23, and at the same time drives the cleaning plate 25 and the magnetic plate 23 to move back and forth left and right, so that the cleaning plate 25 scrubs the iron powder on the magnetic plate 23 and rinses the iron powder on the magnetic plate 23 in the left and right directions.

[0075] In the fifth step, when the cleaning plate 25 moves to the right, the scraper plate 251 scrapes the iron powder on the magnetic plate 23 downward, gradually reducing the thickness of the iron powder on the magnetic plate 23, and the scraper plate 251 moves the iron powder back and forth through the combing groove 253, so that the cleaning plate 25 is in full contact with the iron powder on the magnetic plate 23, ensuring the scrubbing effect.

[0076] In the sixth step, after a fixed time, the telescopic section of the electric cylinder 263 extends to drive the shift frame 28 to reset, and then the servo motor 262 is started to reversely drive the magnetic plate 23 to flip until the iron powder adsorbed on the magnetic plate 23 rotates to the right, and then repeat steps 3 to 6 to continuously clean the iron powder.

[0077] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
