Description

Technical Field

[0001] The invention belongs to the technical field of aluminum liquid refining and impurity removal, in particular to an aluminum refining device for aluminum product casting. Background Art

[0002] In the production process of aluminum alloy, impurities are one of the main factors affecting the quality of aluminum alloy. Therefore, adding different refining agents to the aluminum liquid can significantly improve the performance and quality of the aluminum alloy. The general principle of aluminum liquid refining is to add the refining agent directly or indirectly to the aluminum liquid, so that the impurities in it react with the refining agent to generate non-metallic substances, which settle or float on the surface, thereby improving the purity and quality of the aluminum liquid.

[0003] In the modern aluminum alloy casting industry, in order to obtain high-quality castings, it is necessary to remove gases, impurities, alkali metals, etc. in the aluminum liquid, mainly hydrogen, and it is very important to control the hydrogen content in the aluminum liquid. Aluminum liquid refining equipment can reduce oxides and hydrogen in the aluminum liquid, reduce aluminum loss during slag removal, and also reduce oxides accumulated on the furnace wall.

[0004] In the aluminum liquid refining process, one of the important steps is to remove the oxide and hydrogen impurities in the aluminum liquid to reduce the loss of aluminum. The existing treatment method usually uses powder spray refining equipment, with high-purity inert gas as a carrier, to mix the powdered refining agent into the aluminum liquid, and then cooperates with the stirring process to make the molten aluminum liquid fully contact with the refining agent, thereby promoting the separation of impurities from the aluminum liquid. However, it was found during the operation that due to the poor fluidity of the aluminum liquid, it is difficult to fully stir the aluminum liquid located in the corner, close to the side wall and away from the agitator area through the existing mechanical stirring technology, resulting in insufficient mixing of the aluminum liquid and the refining agent, and insufficient removal of impurities therein, affecting the quality of the aluminum products finally prepared.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] An aluminum refining equipment for aluminum product casting, as shown in the accompanying drawings of the specification Figure 1-Figure 7 As shown, the refining furnace 1 includes a refining furnace 1, a feed port 11 is provided on the front side of the refining furnace 1, and a discharge trough 12 is provided on the back side, and the feed port 11 and the discharge trough 12 are both communicated with the internal refining chamber 13; the discharge trough 12 is communicated with a flow channel 14, and the flow channel 14 is used to send the refined and molten aluminum liquid to the next station for subsequent further degassing and impurity removal treatment; and also includes a powder spraying refining component 2, which is used to refine the aluminum liquid inside the refining chamber 13, and the powder spraying refining component 2 here can select existing aluminum liquid refining auxiliary equipment, such as a furnace powder spraying refining trolley;

[0038] A guide plate 3 is provided on the inner wall of the refining chamber 13 at the upper side of the feed port 11, the side wall of the guide plate 3 is in sliding contact with the inner wall of the refining chamber 13, and a guide port 31 is provided in the middle of the guide plate 3; an installation cavity 15 is provided at the top of the refining chamber 13, and a telescopic device 151 is provided inside the installation cavity 15. The telescopic device 151 here can be an electric telescopic rod device or a steam piston rod device, which is treated to be resistant to high temperature, and the bottom of the installation cavity 15 is made of insulating material to prevent high temperature from entering the installation cavity 15 and affecting the normal operation of the equipment therein; the telescopic end of the telescopic device 151 is made of a high-temperature resistant alloy material and is connected to the upper surface of the guide plate 3.

[0039] Specific work flow: In the aluminum liquid refining process, one of the important steps is to remove the oxide and hydrogen impurities in the aluminum liquid to reduce the loss of aluminum; the existing treatment method usually uses powder spray refining equipment, uses high-purity inert gas as a carrier, mixes the powdered refining agent into the aluminum liquid, and then cooperates with the stirring process to make the molten aluminum liquid fully contact with the refining agent, and promotes the separation of impurities from the aluminum liquid; however, it was found during the operation that due to the poor fluidity of the aluminum liquid, it is difficult to fully stir the aluminum liquid located in the corner, close to the side wall and away from the agitator area through the existing mechanical stirring technology, resulting in insufficient mixing of the aluminum liquid and the refining agent, and insufficient removal of impurities therein, affecting the quality of the aluminum products finally prepared;

[0040] Therefore, in the present application, during the smelting process of molten aluminum, after adding the raw materials into the refining chamber 13 inside the refining furnace 1, heating is started to melt them into molten aluminum through high temperature. When refining and impurity removal is required, the telescopic device 151 located inside the installation cavity 15 is started to move the guide plate 3 downward, and the horizontal shape of the guide plate 3 is similar to the horizontal cross-section of the refining chamber 13, and the edge of the guide plate 3 is in sliding contact with the side wall of the refining chamber 13; in this way, after the guide plate 3 moves downward and contacts the surface of the molten aluminum, the molten aluminum is squeezed to flow upward from the guide port 31 provided on the guide plate 3; in this process, the existing powder spray refining component 2 can be started, so that the working end of the powder spray refining component 2 moves to the position of the guide port 31, and then the molten aluminum flowing upward from the guide port 31 is centrally stirred, and at the same time, the refining agent is mixed into the molten aluminum flowing out from the guide port 31;

[0041] By moving the guide plate 3 downward, the aluminum liquid distributed at different positions in the refining chamber 13 is pressurized and concentrated to flow out from the guide port 31 in a smaller area. The restriction of the flow path of the aluminum liquid makes the aluminum liquid in the refining chamber 13 pass through the guide port 31 in a concentrated manner, and is stirred by the powder spraying refining component 2 to fully mix and react with the sprayed refining agent. In this way, the aluminum liquid in the refining chamber 13 is fully stirred, and the refining agent is fully diffused and exerts its effect, so that the impurities mixed in the aluminum liquid are separated more thoroughly.

[0042] As the guide plate 3 moves down to the bottom of the refining chamber 13, the telescopic device 151 is controlled to move up and reset. During the upward movement, the aluminum liquid located on the upper side of the guide plate 3 flows downward through the guide port 31 again, and the working end of the powder spray refining component 2 is controlled to align with the guide port 31, keep synchronous movement, and stir to remove impurities. This operation is repeated many times to achieve repeated refining and separation of impurities in the aluminum liquid. The feed port 11 can be opened and tools can be used to remove impurities at the liquid surface of the aluminum liquid; it is also possible to choose to open the discharge trough 12 after the reaction and impurity removal are completed, and guide the refined aluminum liquid into the flow channel 14, so that it flows along the flow channel 14 to the degassing and impurity removal filtering equipment for further processing, thereby ensuring the quality of the final aluminum product.

[0043] On the basis of the above, a processing port 131 is vertically provided at the top of the refining chamber 13 directly opposite the guide port 31. The processing port 131 vertically penetrates the top of the refining chamber 13 upward. The processing port 131 is normally kept closed to prevent heat loss. When refining and impurity removal processing is required, it can be opened to facilitate the working end of the powder spraying refining component 2 to pass through.

[0044] A slide 21 is provided on the top upper surface of the refining furnace 1, and the powder spraying refining component 2 is connected to the slide 21 through a sliding base 22. The sliding cooperation between the sliding base 22 and the slide 21 can adopt the cooperation of the existing electric slide rail and the electric slider. Under the action of the external controller, the sliding base 22 is controlled to drive the powder spraying refining component 2 to move along the slide 21; the stirring rotor on the processing end of the powder spraying refining component 2 is embedded in the processing port 131, and the processing end of the powder spraying refining component 2 is vertically reciprocated along the extension direction of the processing port 131 under the control of the reciprocating drive mechanism;

[0045] On the basis of the above-mentioned specific working process, the powder spraying and refining assembly 2 in the present application is different from the existing in-furnace powder spraying and refining trolley. The walking mechanism driven automatically by the wheels is replaced by the fixed track moving mechanism of the sliding base 22 in the present application in cooperation with the slide trough 21. The sliding base 22 is controlled by the controller to drive the powder spraying and refining assembly 2 to slide along the slide trough 21.

[0046] In this way, when the aluminum liquid in the refining chamber 13 needs to be refined, it is not necessary to open the feed port 11, but only to open the smaller processing port 131 at the top, and control the sliding base 22 to drive the powder spray refining component 2 to move along the slide 21 to the position directly above the processing port 131, and then start the powder spray refining component 2, so that the processing end moves downward due to the drive of the reciprocating drive mechanism, and moves downward along the processing port 131 to the inside of the refining chamber 13, because the processing port 131 and the guide port 31 on the guide plate 3 are distributed along the same vertical straight line; therefore, the processing end of the powder spray refining component 2 moving downward along the processing port 131 remains on the upper side of the guide port 31, facing the middle position of the guide port 31;

[0047] In this way, as the guide plate 3 moves vertically, the processing end of the powder spray refining component 2 keeps moving synchronously with the guide plate 3, and the moving trajectories overlap, which makes the coordination smoother and reduces the collision problem that may be caused by the mismatch of moving trajectories; in this process, the powder spray refining component 2 releases the refining agent and repeatedly mixes it with the aluminum liquid flowing in the guide port 31, so as to achieve the refining and impurity removal of the aluminum liquid; by restricting the movement trajectory of the powder spray refining component 2, the synchronous movement of the processing end of the powder spray refining component 2 and the guide plate 3 is made more stable and efficient, further improving the practicality of the present application.

[0048] On the basis of the above, a separation tube 32 is provided at a portion of the upper surface of the guide plate 3 near the outer edge of the guide port 31, and the end of the separation tube 32 extends upward and bulges; an interception plate 321 is provided at an edge portion of the upper surface of the guide plate 3, and the interception plate 321 extends upward, and the top of the interception plate 321 is at the same height as the top of the separation tube 32;

[0049] A slag removal chamber 16 is provided on the side wall of the refining chamber 13, and a liquid inlet 161 of the slag removal chamber 16 is provided on the inner wall of the refining chamber 13, and is located at the gap between the mounting chamber 15 and the guide plate 3; a liquid outlet 162 at the bottom of the slag removal chamber 16 is communicated with the interior of the refining chamber 13, and a filter screen 163 is provided between the liquid inlet 161 and the liquid outlet 162; a notch is provided at a position corresponding to the liquid inlet 161 of the intercepting plate 321, and after the notch and the liquid inlet 161 overlap, it is convenient for the residual high-concentration impurity aluminum liquid to flow into the liquid inlet 161; the liquid inlet 161 and the liquid outlet 162 are usually kept closed to avoid heat loss. When removing impurities, the liquid inlet 161 and the liquid outlet 162 are opened to facilitate the flow of aluminum liquid;

[0050] A mounting rod 33 is provided on the upper surface of the top of the separation tube 32, and the mounting rod 33 is arranged in an annular shape around the central axis of the separation tube 32; an interception net 34 is provided on the outer surface of the mounting rod 33, and the interception net 34 is an annular structure and is fixedly installed around the annularly arranged mounting rod 33; the vertical distance between the top of the interception net 34 and the upper surface of the guide plate 3 is greater than the vertical distance between the bottom of the refining chamber 13 and the feed port 11, so the height of the interception net 34 is greater than the depth of the aluminum liquid;

[0051] On the basis of the above specific working process, during the refining process of the aluminum liquid, the refining agent and the impurities react to form a large amount of solid residues, which are easily adhered to the inner wall of the refining chamber 13 and affect the fluidity of the aluminum liquid; therefore, a slag removal chamber 16 is provided to guide the aluminum liquid inside the refining chamber 13 into the slag removal chamber 16 outside the room, and then the residue is separated by filtration, so that the filtered aluminum liquid returns to the refining chamber 13;

[0052] In order to avoid excessive heat loss during the process of a large amount of aluminum liquid being led out of the refining chamber 13, which leads to an increase in heating energy consumption, an interception net 34, an interception plate 321 and a separation tube 32 are arranged on the guide plate 3, so that the solid residue in the aluminum liquid is concentrated in part of the aluminum liquid, and then this part of the aluminum liquid enriched with residue is introduced into the slag removal chamber 16 for separate slag removal, thereby reducing the workload of filtering treatment and also reducing the heat loss of the aluminum liquid;

[0053] Specifically, an interception net 34 is provided on the upper side of the separation tube 32 on the upper surface of the guide plate 3, and the interception net 34 is fixed by the mounting rod 33, and the height of the interception net 34 is higher than the height of the aluminum liquid inside the refining chamber 13; therefore, during the refining process, the guide plate 3 moves down to the bottom of the refining chamber 13, so that when the aluminum liquid fully flows into the upper side of the guide plate 3, the top of the interception net 34 is still above the liquid level of the aluminum liquid, and during the upward resetting process of the guide plate 3, due to the effect of gravity, the aluminum liquid needs to flow downward through the middle guide port 31, and during this process, the aluminum liquid needs to pass through the middle interception net 34, and the residue in the aluminum liquid is separated by the interception net 34 and enriched on the upper side of the guide plate 3; as the guide plate 3 moves up, until the liquid level of the aluminum liquid on the upper side of the guide plate 3 is flush with the top of the interception plate 321, at this time, the residue content in the part of the aluminum liquid on the upper side of the guide plate 3 is high, and the interception plate 321 and the separation tube 32 play a role of limiting and intercepting this part of the aluminum liquid;

[0054] The guide plate 3 moves to a position corresponding to the liquid inlet 161 of the slag removal chamber 16, the notch of the intercepting plate 321 coincides with the liquid inlet 161, and the liquid inlet 161 is opened, so that the high-concentration residual aluminum liquid on the upper side of the guide plate 3 flows into the slag removal chamber 16, and then passes through the intercepting net 34 inside the slag removal chamber 16, so that the residue in the aluminum liquid is separated, and then flows back to the refining chamber 13 from the liquid outlet 162 at the bottom of the slag removal chamber 16, and re-merges into the aluminum liquid; in this way, only part of the aluminum liquid with high-concentration residual residue needs to be filtered, and the solid residue contained in the smelted aluminum liquid can be fully filtered, which reduces heat consumption and the workload of subsequent deep filtration; the slag removal chamber 16 is located outside the refining chamber 13, and after the refining process, it is also convenient to regularly recover and clean the fixed residue separated from the slag removal chamber 16, so as to ensure the continuous progress of the above-mentioned slag removal and purification process.

[0055] Embodiment 2:

[0056] On the basis of the first embodiment, a cleaning area 152 is provided inside the installation cavity 15, and a through groove 153 is provided at the bottom of the cleaning area 152 corresponding to the separation tube 32, and the cleaning area 152 and the refining chamber 13 are connected through the groove 153;

[0057] A cleaning ring 4 is rotatably provided at the bottom of the cleaning area 152, which is located outside the through groove 153. A cleaning groove 41 is provided on the side wall of the cleaning ring 4 close to the through groove 153. A cleaning roller 42 is rotatably provided in the cleaning groove 41. Bristles are evenly provided on the outer surface of the cleaning roller 42, and the bristles are in contact with the outer surface of the interception net 34. The bottom of the cleaning roller 42 is connected to the output end of the driving device on the inner wall of the cleaning area 152. The bristles here can be made of metal bristles used for cleaning metal adhering residues. The driving device can be a micro motor device, which is controlled by an external controller.

[0058] The annular protrusion at the bottom of the cleaning ring 4 is embedded in the annular groove at the bottom of the cleaning area 152 to achieve a sliding connection, and can be driven by an external driving motor to rotate around the groove 153, so as to better clean the outer surface of the middle interception net 34; there are many possible implementation schemes for the specific rotation method, and a possible technical solution is provided here. For example, an annular gear ring can be provided on the outer circumferential surface of the annular protrusion at the bottom of the cleaning ring 4, and a driving gear is provided on the outer side of the gear ring to mesh with it, and the middle position of the driving gear is connected to the output end of the driving motor. In this way, when the controller controls the driving motor to start, the cleaning ring 4 can be driven to rotate along the annular groove through the meshing action of the gear ring and the driving gear, so as to achieve better cleaning of the middle interception net 34;

[0059] An air filling chamber 43 is provided in the area at the bottom of the cleaning groove 41 inside the cleaning ring 4, and an air supplement chamber 46 is provided at the top of the cleaning groove 41. The air filling chamber 43 and the air supplement chamber 46 are connected through an air filling pipe 461, and an air filling device is provided inside the air filling chamber 43, and an air extraction device is provided inside the air supplement chamber 46.

[0060] A connecting pipe 431 is rotatably provided on the top of the cleaning roller 42, and the connecting pipe 431 is communicated with the inside of the inflation chamber 43; the inflation device and the air extraction device here are both air pump devices, and are controlled by an external controller; the air outlet end of the inflation device is communicated with the inside of the inflation chamber 43, and the air inlet end is communicated with the outside; the air inlet end of the air extraction device is communicated with the inside of the air replenishing chamber 46, and the air outlet end is rotatably connected with the connecting pipe 431, and the air flow drawn in can be introduced into the inside of the connecting pipe 431;

[0061] The cleaning roller 42 is hollow inside to form a tubular structure, and cleaning holes 421 are evenly arranged on the surface of the cleaning roller 42 . The cleaning holes 421 are connected to the inside of the cleaning roller 42 , and the connecting pipe 431 is connected to the hollow area inside the cleaning roller 42 .

[0062] Specific workflow: Based on the specific workflow in Example 1, during the continuous refining process, a large amount of aluminum liquid and residue mixture will accumulate on the outer surface of the interception net 34 during the continuous adhesion process. Because the surface of the interception net 34 is relatively rough, the residue mixture may adhere to the outer surface of the interception net 34, affecting the normal operation of the interception net 34; therefore, a cleaning area 152 and a passing groove 153 are set, so that after the guide plate 3 continues to operate for a period of time, the guide plate 3 is controlled to move up, so that the top of the interception net 34 is embedded in the passing groove 153, and then enters the cleaning area 152 from the passing groove 153;

[0063] Subsequently, the bristles on the surface of the cleaning roller 42 on the cleaning ring 4 in the cleaning area 152 come into contact with the outer surface of the interception net 34, and the controller controls the cleaning ring 4 to rotate around the interception net 34, so that the bristles on the cleaning roller 42 fully and comprehensively rotate to clean the residues adhered to the outer surface of the lower interception net 34; at the same time, the driving device connected to the bottom of the cleaning roller 42 is started, driving the cleaning roller 42 to rotate, and the relative movement between the rotating cleaning roller 42 and the outer surface of the interception net 34 is strengthened. While the rotating bristles scrape off the residues adhered to the outer surface of the interception net 34, the centrifugal effect of the rotation is cooperated to cause the scraped residues to separate from the bristle surface, and as the interception net 34 and the guide plate 3 slide back and forth vertically, each part of the outer surface of the interception net 34 is fully cleaned, thereby ensuring the subsequent normal operation of the interception net 34;

[0064] Furthermore, the air filling device is controlled to start, and the outside air flow is filled into the air filling chamber 43, and then flows into the air supply chamber 46 through the air filling pipe 461. Under the action of the air extraction device, the air flow is sent into the interior of the rotating connecting pipe 431, and then flows into the interior of the hollow cleaning roller 42, and flows out from the cleaning holes 421 on the surface of the cleaning roller 42; because the outside air flow comes from the high-purity inert air filled in during the refining process of the aluminum liquid, the outside air flow temperature is relatively high, and the outside air flow from the cleaning holes is relatively high. 421 flows out to flush the contact gap between the bristles and the interception net 34, which, on the one hand, accelerates the falling off of the residues adhering to the interception net 34. On the other hand, the flushing of the high-temperature hot air flow also slows down the process of the residues being cold-solidified and strengthened, prompting the impurities adhering to the interception net 34 to be heated and softened, accelerating their falling off, and also reducing the cold-solidification of the residues adhering to the bristles. In this way, the residues are separated from the bristles under the flushing of the high-temperature hot air flow, and fall downward into the residual aluminum liquid on the bottom guide plate 3, and then enter the slag removal chamber 16 together for filtration and separation treatment.

[0065] Embodiment three:

[0066] On the basis of the second embodiment, a flushing cavity 44 is provided in the inner wall of the cleaning groove 41, a cleaning block 45 is slidably provided on the inner wall of the flushing cavity 44, and the cleaning block 45 is connected to the inner wall of the flushing groove through an elastic member, and the elastic member here can be a spring;

[0067] The end of the cleaning block 45 slides through the mounting groove 441 provided on the side wall of the flushing chamber 44, and grinding strips 451 are evenly provided on the end of the cleaning block 45, and the gaps between the grinding strips 451 form grinding grooves 452, and the inner walls of the grinding grooves 452 are frosted; the grinding strips 451 and the end of the cleaning block 45 are elastically connected through elastic members, and the elastic members here can also be springs, and the ends of the grinding strips 451 provided with elastic members are slidably embedded in the grooves provided at the corresponding parts of the cleaning block 45, so that the grinding strips 451 maintain lateral reciprocating sliding under the action of external force; the openings on both sides of the grinding groove 452 are conical, and a vibrator is provided inside the cleaning block 45, and the vibrator is controlled by an external controller. The vibrator here is a miniature vibration motor, which is controlled by an external controller.

[0068] Specific working process: Based on the specific working process in the second embodiment, during the rotation of the cleaning roller 42, the bristles, after cleaning the outer surface of the interception net 34, rotate to the side close to the flushing chamber 44, and contact the cleaning block 45 slidably connected in the mounting groove 441; the end of the cleaning block 45 close to the cleaning roller 42 is evenly provided with grinding strips 451 along the vertical direction, and the gaps between adjacent grinding strips 451 form grinding grooves 452, so that when the bristles contact the end of the cleaning block 45, because the grinding grooves 452 are tapered on both sides and have a larger opening, it is convenient for the bristles to enter The brush moves to the gap between the grinding groove 452 and contacts the inner wall of the grinding groove 452, and the airflow flows out horizontally from the cleaning hole 421, causing the bristles to swing horizontally under the scouring of the airflow and keep horizontal, so that the bristles can be easily embedded in the grinding groove 452. The grinding grooves 452 evenly distributed along the vertical direction play a combing role on the bristles, so that the bristles that stick to each other are separated; and because the inner wall surface of the grinding groove 452 is made of frosted material, the bristles contact the inner wall surface after entering the grinding groove 452, so that the residue and hardened aluminum liquid adhering to the bristles fall off due to friction.

[0069] Furthermore, because the cleaning block 45 is elastically connected to the inner wall of the flushing chamber 44, and the grinding strip 451 is connected to the cleaning block 45 by an elastic member, the vibrator inside the cleaning block 45 is started to intensify the vibration of the cleaning block 45, thereby promoting the relative vibration between the grinding strip 451 and the cleaning block 45, and between the connected grinding strips 451. Therefore, after the bristles enter the inner wall of the grinding groove 452, they will be scraped back and forth by the relative movement of the upper and lower grinding strips 451, which further promotes the detachment of residual impurities adhered to the surface of the bristles.

[0070] Embodiment 4:

[0071] On the basis of the third embodiment, a flushing hole 453 is provided at one end of the cleaning block 45 located inside the flushing chamber 44, one end of the flushing hole 453 leads to the grinding groove 452, and the other end communicates with the inside of the flushing chamber 44, and the flushing chamber 44 communicates with the inflation chamber 43; the bottom of the flushing chamber 44 communicates with the inflation chamber 43, and the top of the flushing chamber 44 communicates with the air replenishing chamber 46, and control air valves are provided at the communicating parts, which are controlled by an external controller.

[0072] Specific working process: On the basis of the specific working process in the third embodiment, when cleaning the bristles, the control valve at the junction of the bottom of the flushing chamber 44 and the inflation chamber 43 is kept closed, while the control valve at the junction of the top of the flushing chamber 44 and the air-filling chamber 46 is opened. At this time, the top of the flushing chamber 44 is connected to the air-filling chamber 46; and the air suction device inside the air-filling chamber 46 is working, and the air inside the air-filling chamber 46 is sucked into the connecting pipe 431, so that the inside of the air-filling chamber 46 maintains a negative pressure, prompting the air in the flushing chamber 44 to be sucked into the inside of the air-filling chamber 46; in this way, the air outside the grinding groove 452 is moved toward the inside The flushing hole 453 flows, so that one end of the bristles on the cleaning roller 42 is flushed from the inside to the outside by the cleaning hole 421, and the other end is adsorbed from the outside to the inside by the flushing hole 453, so that the bristles further enter the grinding groove 452, contact the inner wall of the grinding groove 452, and are subjected to the friction cleaning effect to remove the metal residues adhering to the surface of the bristles, thereby ensuring that the bristles function normally; the flushing hole 453 is located deep in the grinding groove 452, and a filter can be set at the opening of the flushing hole 453 to avoid clogging of the opening of the flushing hole 453 due to excessive residues in the adsorbed air, thereby affecting the entry of airflow;

[0073] After the bristle cleaning is completed, when the grinding strip 451 itself needs to be cleaned, the control valve at the junction of the bottom of the scouring chamber 44 and the inflation chamber 43 can be controlled to be opened, while the control valve at the junction of the top of the scouring chamber 44 and the air replenishing chamber 46 can be closed. At this time, the bottom of the scouring chamber 44 remains connected with the inflation chamber 43, and the inflation device located inside the inflation chamber 43 is started to allow the air flow to enter the scouring chamber 44, and then impact from the scouring hole 453 on the side wall of the scouring chamber 44 from the inside to the outside, taking away the residue in the gap of the grinding groove 452, and the impact of the air flow drives the relative vibration between the grinding strips 451, further removing the metal residue adhering to the inner wall of the grinding groove 452, to ensure that the grinding groove 452 functions normally.
