Description

Technical Field

[0001] This invention belongs to the field of dust removal technology for silicon carbide abrasives, and particularly relates to a dust removal device for the production of silicon carbide abrasives. Background Technology

[0002] Silicon carbide abrasive is a type of abrasive with extremely high hardness, commonly used in grinding, polishing, and other surface treatment processes. Silicon carbide abrasive possesses excellent wear resistance, strong chemical stability, and superior thermal conductivity. During production, fine particles are generated due to collisions and friction between the particles. However, since silicon carbide abrasive is in a dry state, dust is produced during these collisions. To improve the grinding efficiency of silicon carbide abrasive on workpieces, dust removal treatment is necessary (dust and impurities can cause uneven contact between the silicon carbide abrasive and the workpiece, thus reducing the grinding efficiency).

[0003] The existing dust removal method typically involves the user adding cleaning fluid to a reaction tank, then placing the silicon carbide abrasive to be cleaned into the tank, allowing the abrasive to come into contact with the cleaning fluid. The abrasive is then stirred to allow lighter impurities and dust to slowly float to the surface of the cleaning fluid. The mixture is then allowed to settle at the bottom of the tank. The waste liquid formed by impurities and dust is then drained, and cleaning fluid is added again, repeating this process until the silicon carbide abrasive reaches the required cleanliness level. During this process, the dust adhering to the silicon carbide abrasive does not immediately detach (dust adhering to the surface is affected by adhesion forces caused by static electricity, etc., which prevent dust from immediately detaching from the surface after entering water). As time and material accumulate, the dust on the lower layer of silicon carbide abrasive remains unable to detach, resulting in incomplete cleaning. Summary of the Invention

[0004] To address the shortcomings mentioned in the background section, the present invention provides a dust removal device for the production of silicon carbide abrasives.

[0005] The technical solution of the present invention is as follows: A dust removal device for silicon carbide abrasive production includes a base, a tank body fixedly connected to the base, a feed pipe fixedly connected and connected to the upper side of the tank body, a liquid inlet pipe fixedly connected and connected to the tank body, a solenoid valve provided on the lower side of the tank body, the solenoid valve being connected to a first discharge pipe, a first drive motor provided on the base, a rotating housing fixedly connected to the drive shaft of the first drive motor and rotatably cooperating with the tank body, a portion of the rotating housing located inside the tank body fixedly connected to a ring-shaped array of fixing members, and a gas guide ring on the lower side of the tank body, the gas guide ring being fixedly connected and connected to a first gas supply. The air guide ring is rotatably engaged with the rotating shell. The rotating shell is fixedly connected to a second air supply pipe arranged in a ring array. All of the second air supply pipes arranged in the ring array are connected to the air guide ring. A one-way valve is provided inside the second air supply pipe. The side of the second air supply pipe away from the rotating shell is located in the adjacent fixed member. The fixed member is provided with an inclined surface. One side of the inclined surface of the fixed member is fixedly connected to a linear array of air outlet pipes. All of the linear array of air outlet pipes are connected to the adjacent second air supply pipes. The fixed member is provided with a material disturbance component for agitating the surrounding materials.

[0006] Furthermore, the material scrambling assembly includes a linear array of rotating rods, each of which is rotatably connected to an adjacent fixing member. Each rotating rod is fixed to a fixing post, and each fixing post is fixed to a fixing shell. The fixing shell is fixed to a first fixing plate arranged in a ring array. The rotating shell is equipped with a drive assembly for rotating the linear array of rotating rods.

[0007] Furthermore, the drive assembly includes a T-shaped frame fixed to the tank body, the T-shaped frame rotatably engaging with the rotating shell, and a portion of the T-shaped frame located inside the rotating shell fixedly connected to a first sprocket arranged in a linear array. Each of the linearly arrayed rotating rods is fixedly connected to a second sprocket. The first sprocket and adjacent second sprockets arranged in a linear array are connected by chain drive. The number of teeth on the first sprocket is greater than the number of teeth on the adjacent second sprocket, and the module of the first sprocket and the adjacent second sprocket are the same, used to change the transmission ratio.

[0008] Furthermore, the device also includes a linear array of support components, which are respectively disposed inside adjacent fixed shells. These support components provide support for adjacent, circularly arrayed first fixed plates. Each support component includes a circular array of sliding members, all of which are slidably connected to adjacent fixed columns. The number of these sliding members is the same as the number of adjacent, circularly arrayed first fixed plates. The sliding members are slidably engaged with the adjacent first fixed plates. A second fixed plate is rotatably connected to the fixed shell, and the second fixed plate is fixedly connected to the adjacent fixed member. A sliding groove is provided on the side of the second fixed plate facing the adjacent fixed shell. The circularly arrayed sliding members are all slidably engaged with the adjacent sliding groove. The sliding groove is located at a different position from the center of the adjacent second fixed plate. The side of the sliding groove furthest from the center of the adjacent second fixed plate has an inclined surface facing the adjacent fixed member. A deflecting component for driving away impurities is disposed inside the tank.

[0009] Furthermore, the driving assembly includes a third air supply pipe, which is fixed to the tank body via a fixing bracket. The third air supply pipe is rotatably connected to and communicates with a first rotating component. The middle part of the third air supply pipe is corrugated. An air bladder is fixed to the outer periphery of the first rotating component. A second drive motor is disposed inside the third air supply pipe and located above the first rotating component. The drive shaft of the second drive motor is splinedly connected to a spline shaft. The side of the spline shaft away from the second drive motor is fixed to the first rotating component. The first rotating component is provided with an annular array of air holes, which are located above the air bladder. The tank body is provided with a fourth air supply pipe fixed to and communicates with the third air supply pipe. An annular array of guide vanes is fixed to the side of the first rotating component facing the bottom of the tank body. A cleaning assembly is disposed on the outer side of the first rotating component for cleaning the bottom of the first rotating component.

[0010] Furthermore, the cleaning assembly includes a second rotating member, which is rotatably connected to the side of the first rotating member away from the third air supply pipe. The side of the second rotating member away from the first rotating member is fixed with an arc-shaped plate arranged in a ring array. An air guide channel communicating with the first rotating member is provided inside the second rotating member, and the upper side of the air guide channel faces the outside of the first rotating member. A material transfer assembly for transferring the material inside the tank is provided on the outside of the tank body.

[0011] Furthermore, the material transfer assembly includes mirror-distributed L-shaped shells, all of which are fixed to the tank body and communicate with it. Inside the tank body, there are mirror-distributed L-shaped guide shells located above the first rotating component. The opposite sides of the mirror-distributed L-shaped guide shells are fixed to and communicate with adjacent L-shaped shells. An auger is rotatably connected inside the L-shaped shells. The mirror-distributed augers are connected to the drive shaft of the first drive motor via pulleys and belts. A liquid guiding assembly for guiding the waste liquid inside the tank body is provided on the outside of the tank body.

[0012] Furthermore, the opposing sides of the mirror-distributed L-shaped guide shells are all oriented towards the side of the tank closest to the first rotating component, so that the material discharged from the L-shaped guide shells can come into contact with the clean cleaning liquid inside the tank.

[0013] Furthermore, the gas outlet pipes, arranged in a linear array, are inclined on the adjacent second gas supply pipes, with the side of the gas outlet pipes away from the adjacent second gas supply pipes facing the inner wall of the tank.

[0014] Furthermore, the liquid guiding assembly includes a second fixing ring, which is fixedly connected to the middle of the outer side of the tank body. A material guiding cavity is provided inside the second fixing ring. A connecting pipe communicating with the material guiding cavity is fixedly connected to one side of the second fixing ring. A blocking member is rotatably connected to the second fixing ring. The blocking member is provided with mirror-distributed electric wheels that rotate in cooperation with the second fixing ring. A discharge port distributed in a ring array is provided in the middle of the tank body. The blocking member and the discharge port distributed in the ring array cooperate to block the discharge port. The material guiding cavity communicates with the tank body through the discharge port distributed in the ring array.

[0015] The beneficial effects of the present invention are as follows: In the process of dust removal of silicon carbide abrasive, the present invention discharges gas through the gas outlet pipe, so that the gas floats upward from the bottom of the tank in the form of bubbles. The rising of the bubbles carries out the dust and impurities on the silicon carbide abrasive, and the bubbles and dust and impurities float upward in the cleaning liquid, so as to achieve the treatment of residual dust and impurities on the silicon carbide abrasive.

[0016] When the silicon carbide abrasive comes into contact with the cleaning fluid in the tank, the dust and impurities in the silicon carbide abrasive float upwards in the cleaning fluid due to their small weight and accumulate on the surface of the cleaning fluid, thus achieving dust removal of the silicon carbide abrasive. Through the contact between the inclined surface of the fixing component and the silicon carbide abrasive, the silicon carbide abrasive is stirred in a bottom-scooping manner, so that the silicon carbide abrasive in the tank does not accumulate in a fixed area. This prevents the dust and impurities in the silicon carbide abrasive in the fixed area from not being able to contact the cleaning fluid, which would increase the dust removal time of the silicon carbide abrasive. Furthermore, through the rotation of the fixing shell and the adjacent first fixing plate distributed in a ring array, the surrounding silicon carbide abrasive is disturbed, so that the silicon carbide abrasive exists in the tank in a dynamic manner, thereby improving the cleanliness of the silicon carbide abrasive at the bottom of the tank.

[0017] During the dust removal process of silicon carbide abrasive, the gas discharged through the annular array of vents on the first rotating component blows the dust and impurities floating on the surface of the cleaning fluid from the center of the tank to the surrounding areas, causing the dust and impurities to move towards the inner wall of the tank and accumulate there for subsequent discharge. The continuous rotation of the auger ensures repeated contact between the silicon carbide abrasive at the bottom of the tank and the cleaning fluid inside, enhancing the dust removal effect and focusing on cleaning the silicon carbide abrasive deposited at the bottom of the tank. The sliding component supports the adjacent first fixed plate, allowing the first fixed plate to transfer the silicon carbide abrasive towards the inner wall of the tank during rotation. Under the action of the chain drive on the two adjacent second sprockets, the silicon carbide abrasive is sequentially transferred towards the inner wall of the tank, thus completing the transfer of the silicon carbide abrasive at the bottom of the tank. This prevents the silicon carbide abrasive near the center of the bottom of the tank from being unable to be transported upwards when the auger rotates. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The technical problems solved by the two embodiments of the present invention are: how to improve the cleanliness of silicon carbide abrasive, how to shorten the reaction (precipitation) time of silicon carbide abrasive, how to reduce water waste, how to deal with the dust and impurities remaining on the silicon carbide abrasive at the bottom of the tank, and how to uniformly transfer the silicon carbide abrasive at the bottom. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: A dust removal device for silicon carbide abrasive production, please refer to... Figures 1-6The system includes a base 10, a tank 11 fixedly connected to the upper side of the base 10, a control panel on the tank 11, a feed pipe 12 for supplying silicon carbide abrasive fixedly connected and connected to the upper side of the tank 11, a liquid inlet pipe 13 fixedly connected and connected to one side of the tank 11 for supplying cleaning fluid to remove dust and impurities from the outside of the silicon carbide abrasive, a solenoid valve 14 electrically connected to the control panel on the lower side of the tank 11, a first discharge pipe 15 connected to the lower side of the solenoid valve 14 for discharging the silicon carbide abrasive after the dust removal step, and a first drive motor 16 electrically connected to the control panel on the upper side of the base 10. The drive shaft of the first drive motor 16 is fixedly connected to a rotating housing 17. The rotating housing 17 is in a sealed rotatable engagement with the lower side of the tank body 11. The portion of the rotating housing 17 located inside the tank body 11 is fixedly connected to two fixed members 18 arranged in a ring array. When the ring array of fixed members 18 rotates with the rotating housing 17, it agitates the silicon carbide abrasive deposited at the bottom of the tank body 11. A gas guide ring 19 is fixedly connected to the lower side of the tank body 11. The gas guide ring 19 is fixedly connected to and connected to a first gas supply pipe 1901 for providing gas. The gas guide ring 19 is in a sealed rotatable engagement with the rotating housing 17. Each of the ring array of fixed members 18 is fixedly connected to a second gas supply pipe 1902. The opposing portions of the second gas supply pipes 1902 are all located inside the rotating housing 17. The second gas supply pipes 1902, arranged in a ring array, are all connected to the gas guide ring 19. A one-way valve is installed inside each second gas supply pipe 1902. The fixing member 18 has an inclined surface, and a linear array of gas outlet pipes 1903 is fixedly connected to one side of the inclined surface of the fixing member 18. Each linear array of gas outlet pipes 1903 is connected to an adjacent second gas supply pipe 1902. When gas enters the second gas supply pipe 1902 and is ejected from the adjacent linear array of gas outlet pipes 1903, the one-way valve inside the second gas supply pipe 1902 is open; otherwise, the gas is no longer ejected from the adjacent linear array of gas outlet pipes. When the second gas supply pipe 1902 enters the adjacent and linearly arrayed gas outlet pipes 1903, the one-way valve in the second gas supply pipe 1902 is closed. When the gas is ejected from the gas outlet pipe 1903, the gas comes into contact with the cleaning liquid in the tank 11, causing the gas to float upward from the bottom of the tank 11 in the form of bubbles. Through the contact between the floating bubbles and the silicon carbide abrasive, the dust and impurities on the silicon carbide abrasive are carried out, causing the bubbles and dust and impurities to float upward in the cleaning liquid, thereby achieving the treatment of residual dust and impurities on the silicon carbide abrasive. The fixing member 18 is equipped with a material disturbance component 2 for driving and disturbing the surrounding materials.

[0035] Please refer to Figure 5 , Figure 7 , Figure 9 and Figure 10The agitation assembly 2 includes a linear array of rotating rods 20, each of which is rotatably connected to an adjacent fixing member 18. Each rotating rod 20 is fixedly connected to a fixing post 21, and the fixing post 21 is fixedly connected to a fixing shell 22. Four first fixing plates 23, arranged in a ring array, are fixedly connected to the outer periphery of the fixing shell 22. The first fixing plates 23 are made of silicone. When the four first fixing plates 23 rotate with the adjacent fixing shell 22, the first fixing plates 23 agitate the surrounding silicon carbide abrasive in a soft state, causing the silicon carbide abrasive to exist dynamically within the tank 11, thereby improving the cleanliness of the silicon carbide abrasive at the bottom of the tank 11. A drive assembly 3 is installed inside the rotating shell 17, which drives the linear array of rotating rods 20 to rotate.

[0036] Please refer to Figures 3-5 , Figure 7 and Figure 8 The drive assembly 3 includes a T-shaped frame 30 fixedly connected to the tank body 11. The T-shaped frame 30 is sealed and rotatably engaged with the rotating shell 17. A first sprocket 31, arranged in a vertical linear array along the central axis of the T-shaped frame 30, is fixedly connected to the lower part of the T-shaped frame 30 located inside the rotating shell 17. Second sprockets 32 are fixedly connected to the lower sides of the linearly arrayed rotating rods 20. The first sprockets 31 and the adjacent, linearly arrayed second sprockets 32 are connected via chain drive (e.g., ...). Figure 8 As shown, in order to make the chain fit with the adjacent second sprockets 32 which are arranged in a linear array, the part of the chain located inside the adjacent fixing member 18 is fitted with the inner side of the adjacent fixing member 18. Therefore, it is known that the inner side of the fixing member 18 will limit the adjacent chain. The number of teeth of the second sprocket 32 ​​is less than the number of teeth of the adjacent first sprocket 31. The first sprocket 31 and the adjacent second sprocket 32 ​​have the same module, which is used to change the transmission ratio.

[0037] During the production process, silicon carbide abrasive generates fine particles (which are considered impurities in this invention) due to collisions and friction between particles. Since silicon carbide abrasive is in a dry state, dust is generated during the collisions between the particles. Dust and impurities affect the grinding efficiency of the silicon carbide abrasive on the workpiece in the later stages (dust and impurities cause uneven contact between the silicon carbide abrasive and the workpiece, thus reducing the grinding efficiency). In order to improve the cleanliness of silicon carbide abrasive, this invention uses water washing to remove dust from the silicon carbide abrasive. The specific steps of water washing are described below.

[0038] Before dust removal from the silicon carbide abrasive, the user connects the left side of the inlet pipe 13 to the outlet of an external pump. The user then operates the external pump to deliver cleaning fluid into the inlet pipe 13. The cleaning fluid is then delivered to the tank 11 through the inlet pipe 13. Once the cleaning fluid level in the tank 11 has submerged the middle of the tank, the user stops delivering cleaning fluid into the tank 11 through the external pump. The user then places an appropriate amount of silicon carbide abrasive (the appropriate amount is the amount suitable for the work) into the tank 11 through the feed pipe 12 and brings it into contact with the cleaning fluid. When the silicon carbide abrasive comes into contact with the cleaning fluid in the tank 11, the dust and impurities in the silicon carbide abrasive float upwards in the cleaning fluid due to their small weight and accumulate on the surface of the cleaning fluid, thereby achieving dust removal from the silicon carbide abrasive.

[0039] During the dust removal process of silicon carbide abrasive, the user starts the first drive motor 16 through the control panel. The drive shaft of the first drive motor 16 drives the rotating shell 17 and the two fixed parts 18 to rotate counterclockwise. During the counterclockwise rotation of the two fixed parts 18, the silicon carbide abrasive in the tank 11 is stirred. When the two fixed parts 18 rotate counterclockwise, the inclined surface on the fixed parts 18 contacts the silicon carbide abrasive. Through the contact between the inclined surface on the fixed parts 18 and the silicon carbide abrasive, the silicon carbide abrasive is stirred in a bottom-stirring manner, so that the silicon carbide abrasive in the tank 11 does not accumulate in a fixed area. This prevents the dust and impurities of the silicon carbide abrasive in the fixed area from not being able to contact the cleaning fluid, which would increase the dust removal time of the silicon carbide abrasive.

[0040] When the time required for sedimentation of the silicon carbide abrasive in tank 11 is reached, the user inserts the suction pipe of the external suction device into tank 11 to extract the waste liquid on the upper layer of the cleaning fluid (because dust and impurities are small, they float on the top of the cleaning fluid, making the upper layer of cleaning fluid waste liquid). After the external suction device extracts the waste liquid, the user again pumps cleaning fluid into inlet pipe 13 (when the liquid level in tank 11 reaches the height before extraction, the user stops pumping cleaning fluid into inlet pipe 13). The dust and impurities in the silicon carbide abrasive float upward under the action of gravity, and the silicon carbide abrasive settles at the bottom of tank 11 under the action of gravity. When the time required for sedimentation of the silicon carbide abrasive in tank 11 is reached again, the user repeats the above liquid replacement operation multiple times until the cleanliness of the silicon carbide abrasive reaches the required level for operation (the user can judge the cleanliness of the silicon carbide abrasive based on the cleanliness of the waste liquid discharged each time).

[0041] To prevent dust and impurities from not completely detaching from the silicon carbide abrasive after it falls to the bottom of the tank 11, and to ensure that dust and impurities remain on the silicon carbide abrasive at the bottom of the tank 11 as time and material increase, thus preventing the dust and impurities from being completely cleaned, the following explanation addresses the aforementioned problems.

[0042] During the processing of the silicon carbide abrasive inside the tank 11, the user connects the first air supply pipe 1901 to the air outlet of an external air intake device. The external air intake device then supplies gas into the first air supply pipe 1901. The first air supply pipe 1901 delivers the gas to the air guide ring 19, which in turn delivers the gas to the two rotating second air supply pipes 1902. (As mentioned earlier, the two fixing members 18 rotate, and the fixing members 18 and the adjacent second air supply pipes 1902 are fixedly connected; therefore, the two second air supply pipes 1902 are...) (Simultaneous rotation) The gas entering the second gas supply pipe 1902 opens the one-way valve inside, allowing the gas to enter the adjacent gas outlet pipes 1903, which are arranged in a linear array, and spray out from the upper side. The gas sprayed out from the upper side of the gas outlet pipe 1903 then comes into contact with the cleaning liquid in the tank 11, causing the gas to float upward from the bottom of the tank 11 in the form of bubbles. Through the contact between the floating bubbles and the silicon carbide abrasive, the dust and impurities on the silicon carbide abrasive are carried out, and the bubbles and dust and impurities float upward in the cleaning liquid, thereby achieving the treatment of residual dust and impurities on the silicon carbide abrasive.

[0043] During the rotation of the rotating shell 17, the two fixed parts 18 rotate counterclockwise. The rotating shell 17 rotates counterclockwise along the T-shaped frame 30. Under the action of the T-shaped frame 30 and the two first sprockets 31 fixed thereon, the two fixed parts 18 rotate circumferentially with the two first sprockets 31 as the reference. Through the cooperation of the first sprockets 31 with the adjacent second sprockets 32 arranged in a linear array, the chain on the first sprockets 31 drives the adjacent second sprockets 32 arranged in a linear array to rotate. Taking the rotation process of one of the second sprockets 32 as an example, the rotation of the second sprocket 32 ​​drives the adjacent rotating rod 20, fixed column 21, fixed shell 22 and the four adjacent first fixed plates 23 arranged in a ring array to rotate. During the rotation of the fixed shell 22 and the four adjacent first fixed plates 23 arranged in a ring array, the surrounding silicon carbide abrasive is disturbed, so that the silicon carbide abrasive at the bottom of the tank 11 exists in the tank 11 in a dynamic manner, thereby improving the cleanliness of the silicon carbide abrasive at the bottom of the tank 11.

[0044] After the dust removal of the silicon carbide abrasive is completed, the user turns off the first drive motor 16 through the control panel and stops the operation of the external air intake device. Then, the user opens the solenoid valve 14 through the control panel, and the cleaning fluid and silicon carbide abrasive in the tank 11 are discharged through the first discharge pipe 15. At this time, the user closes the solenoid valve 14 through the control panel. When it is necessary to remove dust from the silicon carbide abrasive again, the above operation can be repeated.

[0045] Example 2: Based on Example 1, please refer to 8- Figure 10 The device also includes a linear array of support components 4, which are respectively disposed inside adjacent fixed shells 22. The support components 4 provide support for adjacent first fixed plates 23 arranged in a ring array. Each support component 4 includes four sliding members 40 arranged in a ring array, each slidingly connected to an adjacent fixed post 21. The number of sliding members 40 is the same as the number of adjacent first fixed plates 23 arranged in a ring array. The sliding members 40 slide in cooperation with the adjacent first fixed plates 23. When the sliding members 40 slide within the adjacent first fixed plates 23, they provide support, causing the first fixed plates 23 to change from soft to hard. The rotation of the first fixed plates 23 transfers the surrounding silicon carbide abrasive towards the inner wall of the tank 11. The fixed shell 22 is rotatably connected to a second fixed plate 41 fixed to an adjacent fixed member 18. The upper side of the second fixed plate 41 is provided with a sliding groove 42. Figure 10 Taking the perspective of the sliding groove 42 as an example, the distance between the front side of the sliding groove 42 and the center of the adjacent second fixed plate 41 is greater than the distance between the rear side of the sliding groove 42 and the center of the adjacent second fixed plate 41. The sliding parts 40 distributed in a ring array are all sealed and slidingly engaged with the adjacent sliding groove 42. The side of the sliding groove 42 that is far from the center of the adjacent second fixed plate 41 faces the adjacent fixed part 18. Through the cooperation between the sliding part 40 and the adjacent sliding groove 42, the sliding part 40 supports the adjacent first fixed plate 23, and the silicon carbide abrasive is transferred to the inner wall of the tank 11 during the rotation of the first fixed plate 23. Under the action of the chain drive on the two adjacent second sprockets 32, the silicon carbide abrasive is transferred to the inner wall of the tank 11 in sequence, thereby completing the transfer of silicon carbide abrasive at the bottom of the tank 11. The tank 11 is equipped with a driving component 5 for driving away impurities.

[0046] Please refer to Figure 3 , Figure 11 and Figure 12The driving assembly 5 includes a third air supply pipe 50, which is fixedly connected to the tank 11 by a fixing bracket. A conical diverter plate is fixedly connected to one side of the tank 11 near its top. The conical diverter plate is used to divert the cleaning liquid conveyed downward by the feed pipe 12. The lower side of the third air supply pipe 50 is sealed and rotatably connected to and communicates with a first rotating member 51. The first rotating member 51 is gyroscope-shaped, and the tip of the first rotating member 51 faces downward. The middle part of the third air supply pipe 50 is designed to facilitate its pulling. The first rotating component 51 has a corrugated shape and an air bladder fixed to its outer periphery. The air bladder is used to make the first rotating component 51 float on the surface of the cleaning fluid. A second drive motor 52, which is electrically connected to the control panel, is installed on the upper side of the third air supply pipe 50. The second drive motor 52 is located above the first rotating component 51. The drive shaft of the second drive motor 52 is splinedly connected to a splined shaft 53. The lower side of the splined shaft 53 is fixedly connected to the upper side of the first rotating component 51. A ring array is provided on the outer periphery of the first rotating component 51. The air vents arranged in a ring around the first rotating member 51 blow dust and impurities floating on the surface of the cleaning fluid from the center of the tank 11 to the surrounding area, causing the dust and impurities to move towards the inner wall of the tank 11 and accumulate there for subsequent discharge. This keeps the cleaning fluid around the first rotating member 51 clean. The air vents arranged in a ring around the first rotating member 51 are located above the air bladder. A fourth air supply pipe 54, which is fixedly connected to and communicates with the third air supply pipe 50, is provided on the upper left side of the tank 11. A spiral-shaped guide vane 55 is fixedly connected to the lower side of the first rotating member 51. The spiral-shaped guide vane 55 guides the dust and impurities at the bottom of the first rotating member 51 as it rotates, causing them to move to the surrounding area. A cleaning component 6 for cleaning the bottom of the first rotating member 51 is provided on the outer side of the first rotating member 51.

[0047] Please refer to Figure 12 and Figure 13 The cleaning component 6 includes a second rotating component 60 that is rotatably connected to the lower side of the first rotating component 51. The second rotating component 60 has an air guide channel that communicates with the first rotating component 51, and the upper side of the air guide channel faces the outside of the first rotating component 51. The lower side of the second rotating component 60 is fixed with an arc-shaped plate 61 arranged in a ring array. The arc-shaped plate 61 arranged in a ring array is used to provide resistance to the second rotating component 60 when it comes into contact with the cleaning fluid. The outside of the tank body 11 is provided with a material transfer component 7 for transferring the material inside.

[0048] Please refer to 2- Figure 4The material transfer assembly 7 includes two L-shaped shells 70 arranged in a left-right mirror image. Both L-shaped shells 70 are fixedly connected to the tank body 11, and their lower sides communicate with the lower side of the tank body 11. Two L-shaped guide shells 71 are disposed inside the tank body 11, both positioned above the first rotating member 51. The opposing sides of the two L-shaped guide shells 71 are fixedly connected to and communicate with adjacent L-shaped shells 70. The opposing sides of the mirror-distributed L-shaped guide shells 71 face towards the side of the tank body 11 closest to the first rotating member 51, for the purpose of guiding the L-shaped guide shells 71... The discharged material can come into contact with the clean cleaning fluid inside the tank 11. An auger 72 is rotatably connected inside the L-shaped shell 70. During the rotation of the auger 72, the silicon carbide abrasive is transferred from the bottom to the top, thereby completing the transfer of silicon carbide abrasive at the bottom of the tank 11. The lower sides of the two augers 72, which are distributed in a mirror image on the left and right, are connected to the drive shaft of the first drive motor 16 through a pulley belt drive. A liquid guiding component 8 is provided on the outside of the tank 11 to guide the waste liquid inside out. The air outlet pipes 1903, which are arranged in a linear array, are inclined on the adjacent second air supply pipes 1902. The side of the air outlet pipes 1903 away from the adjacent second air supply pipes 1902 faces the inner wall of the tank 11.

[0049] Please refer to Figure 2 , Figure 3 , Figure 11 and Figure 14 The liquid guiding assembly 8 includes a second fixing ring 80 fixed to the middle of the outer side of the tank body 11. A guiding cavity 81 is provided inside the second fixing ring 80. The cross-section of the guiding cavity 81 consists of inclined grooves and straight grooves. The guiding cavity 81 is used to guide waste liquid. A connecting pipe communicating with the guiding cavity 81 is fixed to the rear side of the second fixing ring 80. A blocking member 82 is rotatably connected to the second fixing ring 80. The blocking member 82 consists of mutually fixed fixing rings and blocking blocks arranged in a ring array. Two electric wheels 83 are arranged on the outer side of the blocking member 82 in a left-right mirror distribution. The wheel 83 is electrically connected to the control panel. The two electric wheels 83, which are mirror-distributed on the left and right, are rotated and engaged with the second fixed ring 80 on their opposite sides. The middle part of the tank body 11 is provided with a circular array of discharge ports 84. The blocking block on the blocking member 82 is engaged with the adjacent discharge port 84. The guide chamber 81 is connected to the tank body 11 through the circular array of discharge ports 84. When the blocking member 82 rotates to no longer block the circular array of discharge ports 84, the waste liquid in the tank body 11 can flow into the guide chamber 81 through the circular array of discharge ports 84.

[0050] Because the dust and impurities floating on the surface of the cleaning fluid are distributed irregularly, when the waste liquid is extracted from the cleaning fluid, the clean cleaning fluid will be discharged along with the waste liquid, resulting in a waste of water resources. The above-mentioned problem is now solved through the following description.

[0051] During the process of conveying cleaning fluid into the tank 11, the middle part of the third air pipe 50 is stretched under the gravity provided by the first rotating part 51 on the lower side. As the level of the cleaning fluid in the tank 11 rises, the first rotating part 51 and its outer air bladder come into contact with the cleaning fluid in the tank 11. Under the buoyancy provided by the outer air bladder of the first rotating part 51, the first rotating part 51 and its parts move upward along with the rise of the cleaning fluid level (the corrugated pipe in the middle of the third air pipe 50 is compressed). When the level of the cleaning fluid is in the middle of the tank 11, the filling of the cleaning fluid is completed. At this time, the level of the cleaning fluid is above the annular array of discharge ports 84.

[0052] After the cleaning fluid is filled, the user connects the left side of the fourth air supply pipe 54 to the air outlet of the external air intake device. The external air intake device delivers gas through the fourth air supply pipe 54 to the third air supply pipe 50. The gas in the third air supply pipe 50 then enters the first rotating member 51. Part of the gas is discharged through the annular array of air holes on the first rotating member 51. The gas discharged through the annular array of air holes on the first rotating member 51 blows the dust and impurities floating on the surface of the cleaning fluid from the center of the tank 11 to the surrounding area, causing the dust and impurities to move towards the inner wall of the tank 11 and accumulate on the inner wall of the tank 11 for subsequent discharge. The other part of the gas enters the second rotating member 60 and is discharged through the air guide channel inside it.

[0053] To maintain the uniformity of dust and impurities moving towards the inner wall of the tank 11, the user turns on the second drive motor 52 via the control panel. The second drive motor 52 drives the first rotating component 51 to rotate via the spline shaft 53. During the rotation of the first rotating component 51, the guide vanes 55 distributed in a ring array at its bottom also rotate, guiding the dust and impurities at the bottom of the first rotating component 51 to move to its surroundings. The rotation of the first rotating component 51 also causes the air holes distributed in a ring array on the first rotating component 51 to drive away the surrounding dust and impurities in a rotating manner, so that the dust and impurities are evenly gathered on the inner wall of the tank 11, thereby completing the collection of dust and impurities.

[0054] During the rotation of the first rotating component 51, it drives the parts below it to rotate. Under the resistance provided by the arc-shaped plates 61 distributed in a ring array, the second rotating component 60 will not rotate synchronously with the first rotating component 51 during the rotation of the first rotating component 51.

[0055] To achieve uniform blowing on the lower side of the first rotating component 51 and enhance the upward transfer speed of dust and impurities on the lower side of the first rotating component 51, the following detailed explanation is provided. Taking the rotation of the first rotating component 51 as a reference, when the first rotating component 51 rotates, the resistance provided to the second rotating component 60 by the arc-shaped plates 61 distributed in a ring array causes the second rotating component 60 to be misaligned with the first rotating component 51. With the cleaning liquid in the tank 11 remaining stationary, the second rotating component 60 is stationary. At this time, the gas ejected through the air guide channel in the second rotating component 60 blows on the lower side of the first rotating component 51, accelerating the upward transfer speed of dust and impurities on the lower side of the first rotating component 51.

[0056] To prevent silicon carbide abrasive from accumulating at the bottom of the tank 11 for extended periods, thus preventing the accumulation of dust and impurities, this invention employs a method of repositioning the silicon carbide abrasive to address the aforementioned problem. Details are as follows: The drive shaft of the first drive motor 16 transmits power to two augers 72 via a pulley belt. During rotation, the augers 72 move the silicon carbide abrasive from the bottom of the tank 11 upwards, causing it to slide out from the upper side of the L-shaped guide shell 71. Under the action of the upper side of the L-shaped guide shell 71 towards the first rotating member 51, the silicon carbide abrasive... The silicon abrasive falls into a clean cleaning fluid (because the annular array of pores on the first rotating part 51 has driven dust and impurities to the surrounding area, the cleaning fluid around the first rotating part 51 is clean). Then, the cleaning fluid repeatedly cleans the silicon carbide abrasive (and achieves repeated dust removal of the silicon carbide abrasive), removing residual dust and impurities from the silicon carbide abrasive. Through the continuous rotation of the auger 72, the silicon carbide abrasive at the bottom of the tank 11 repeatedly contacts the cleaning fluid inside, enhancing the dust removal effect on the silicon carbide abrasive, and focusing on cleaning the silicon carbide abrasive deposited at the bottom of the tank 11.

[0057] To further improve the cleanliness of the silicon carbide abrasive at the bottom of the tank 11, the above-mentioned effects are described below. When the rotating rod 20 drives the fixed column 21 and its parts to rotate, the four adjacent sliding members 40 arranged in a circular array on the fixed column 21 slide along the adjacent sliding grooves 42. When one of the sliding members 40 slides along the sliding groove 42 to the side farthest from the center, the sliding member 40 slides into the adjacent first fixed plate 23, providing support for the adjacent first fixed plate 23 (as mentioned in Embodiment 1, the first fixed plate 23 rotates with the adjacent fixed shell 22, providing support for the surrounding area). The silicon carbide abrasive is disturbed. Since the first fixed plate 23 is made of soft silicone, it is known that when the first fixed plate 23 lacks the support of the adjacent sliding member 40, the first fixed plate 23 disturbs the surrounding silicon carbide abrasive in a soft state. Through the support of the adjacent first fixed plate 23 by the sliding member 40, the silicon carbide abrasive is transferred to the inner wall of the tank 11 during the rotation of the first fixed plate 23. Under the action of the chain drive on the two adjacent second sprockets 32, the silicon carbide abrasive is transferred to the inner wall of the tank 11 in sequence, thereby completing the transfer of silicon carbide abrasive at the bottom of the tank 11.

[0058] When the fixed column 21 drives the adjacent sliding member 40 to slide to the side of the sliding groove 42 closest to the center, the sliding member 40 slides towards the center of the adjacent second fixed plate 41 and disengages from the support of the adjacent first fixed plate 23, so as to realize intermittent support for the adjacent sliding member 40 and avoid the sliding member 40 supporting the adjacent first fixed plate 23 for a long time, which would prevent the first fixed plate 23 from transferring the surrounding silicon carbide abrasive.

[0059] When it is necessary to discharge the waste liquid in the tank 11, the user controls the two electric wheels 83 via the control panel to drive the blocking member 82 to rotate (the electric wheels 83 rotate along the second fixed ring 80 during rotation, thereby driving the blocking member 82 to rotate). During the rotation of the blocking member 82, the blocking block on it is released from blocking the adjacent discharge port 84, so that the waste liquid in the tank 11 can flow into the guide chamber 81 through the annular array of discharge ports 84, and then be discharged from the lower connecting pipe through the guide chamber 81. As the level of the cleaning liquid in the tank 11 decreases, the first rotating member 51 moves downward along the decrease of the cleaning liquid level under the action of gravity provided by its upper parts (the first rotating member 51 moves downward along the decrease of the cleaning liquid level). As the rotating part 51 moves downward, the middle part of the third air supply pipe 50 is stretched. During the discharge of waste liquid from the annular array distribution outlet 84, impurities and dust near the inner wall of the tank 11 are discharged from the annular array distribution outlet 84 at the first moment. When the liquid level of the cleaning liquid in the tank 11 is lower than the height of the annular array distribution outlet 84, the waste liquid in the tank 11 has been discharged, thus completing the discharge of waste liquid. After the waste liquid is discharged, the user controls the two electric wheels 83 through the control panel to drive the blocking part 82 to rotate in the opposite direction, so that the blocking block on the blocking part 82 blocks the adjacent outlet 84. Then the user repeats the above-mentioned method of adding cleaning liquid to perform the operation.

[0060] After the dust removal of the silicon carbide abrasive is completed, the user can repeat the above discharge operation steps.

All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention are existing technologies known to those skilled in the art.
