Description

Technical Field

[0001] This invention belongs to the technical field of surface grinding equipment in the manufacturing process of titanium alloy materials, and specifically relates to a cleaning device for titanium alloy consumable melting and casting ingots. Background Technology

[0002] Titanium alloy ingots are cast in a vacuum arc remelting furnace. High-quality titanium alloy ingots generally require three vacuum arc remelting processes. The ingot from the third (final) vacuum arc remelting process is the finished ingot, which needs to be machined to remove the oxygen- and nitrogen-rich outer layer from its surface. However, the titanium alloy ingots from the first and second vacuum arc remelting processes require surface cleaning through grinding. This is because the surfaces of these ingots from the second vacuum arc remelting process contain a significant amount of attached impurities. In particular, due to the unavoidable presence of various low-melting-point volatiles during the production of sponge titanium—the raw material for titanium alloy ingots—these substances will inevitably appear on the surface of the arc remelting ingot. Especially during the first arc remelting process, the surface of the ingot will contain a relatively high amount of low-melting-point salt impurities. If these impurities are not cleaned properly, they will be carried into the ingot from the second vacuum arc remelting process, causing quality problems. Furthermore, due to variations in smelting process parameters during ingot casting, the degree of contamination on the ingot surface varies. Specifically, the degree of deposits on the upper, middle, and lower parts of the ingot surface differs. If the ingot is machined on a lathe or other processing equipment, the surface, being less dense after the initial consumable melting process, will contain pores and depressions of varying depths, making complete removal extremely difficult and resulting in significant material loss. Therefore, alternative methods for ingot surface treatment are necessary. Current ingot cleaning methods involve manual grinding with grinding wheels or wire wheels. However, due to the increasing size of titanium alloy ingots in recent years, this traditional method is not only labor-intensive and inefficient, but also fails to guarantee the cleaning quality of high-quality titanium alloy ingots. Therefore, to reduce the impact of human factors on the treatment effect and quality, it is necessary to improve existing titanium alloy ingot cleaning methods and equipment. Summary of the Invention

[0003] This invention addresses the aforementioned problems by providing a highly practical titanium alloy consumable smelting ingot cleaning device that can thoroughly remove impurities adhering to the surface of ingots, especially impurities inside the pores on the surface of ingots, effectively improve the working environment, avoid dust pollution, increase work efficiency, and ensure the polishing quality of titanium alloy ingot surfaces.

[0004] The technical solution adopted in this invention is as follows: the titanium alloy consumable melting ingot cleaning equipment includes a machine base, characterized in that: two sets of parallel spiral rollers for continuously conveying ingot workpieces are arranged on the machine base, the two ends of the spiral rollers are rotatably connected to the ends of the machine base, and the driving ends of the two sets of spiral rollers are connected to the output end of the roller drive motor located at the feed end through a roller transmission mechanism; a closed cleaning box is provided in the middle of the machine base and above the spiral rollers, and ingot passage openings are respectively provided on the front and rear sides along the axial direction of the spiral rollers on the closed cleaning box; a lifting platform is provided on the top of the closed cleaning box, and a rust removal and cleaning mechanism is provided on the lifting platform facing the interior of the closed cleaning box.

[0005] The lifting platform is equipped with platform lifting guide posts at its four corners, allowing it to be movably mounted within platform lifting guide grooves on the outer wall of the enclosed cleaning chamber. Telescopic folding sealing mechanisms are installed between the lifting platform and the top of the enclosed cleaning chamber. A flexible rubber sealing ring, adaptable to different workpiece diameters, is installed between the ingot's opening and the outer wall of the workpiece. A platform lifting mechanism is also installed between the lifting platform and the enclosed cleaning chamber, with its drive end connected to the output end of a platform lifting drive motor. The platform lifting drive motor drives the platform lifting mechanism, causing the lifting platform to reciprocate under the guidance of the platform lifting guide posts and grooves, thus enabling the rust removal and cleaning mechanism on the lifting platform to accommodate ingots of different diameters.

[0006] The platform lifting mechanism includes a platform lifting guide worm fixedly mounted on the upper part of the enclosed cleaning box. The vertically arranged platform lifting guide worm meshes with a platform lifting transmission worm wheel rotatably mounted on the lifting platform, and the rotation shaft of the platform lifting transmission worm wheel is connected to the output end of the platform lifting drive motor. The lifting platform is driven to rise and fall above the top of the enclosed cleaning box through the interaction between the platform lifting transmission worm wheel and the vertically arranged platform lifting guide worm.

[0007] The rust removal and cleaning mechanism includes a rust removal and cleaning wheel assembly. The two ends of the connecting shaft in the middle of the rust removal and cleaning wheel assembly are respectively connected to the drive bearing seats of the cleaning wheel assembly fixedly installed on the top of the enclosed cleaning box. The drive end of the connecting shaft of the rust removal and cleaning wheel assembly is also connected to the output end of the rust removal and cleaning motor through a rust removal and cleaning transmission mechanism. The rust removal and cleaning motor and the rust removal and cleaning transmission mechanism are used to drive the rust removal and cleaning wheel assembly arranged on the drive bearing seats of the cleaning wheel assembly on both sides to rotate continuously, thereby cleaning the surface contaminants of the ingot workpiece that rotates forward with the two sets of spiral roller shafts.

[0008] The rust removal and cleaning wheel set includes a first rust removal and cleaning wheel set and a second rust removal and cleaning wheel set movably arranged above the drive bearing seat of the cleaning wheel set. Both the first and second rust removal and cleaning wheel sets include a cleaning wheel set suspension shaft. Two sets of cleaning wheel set shifting swing arms are fixedly mounted on the cleaning wheel set suspension shaft. The drive end of the cleaning wheel set suspension shaft is connected to the output end of the swing arm drive motor. The front end of each cleaning wheel set shifting swing arm is also hinged with a cleaning wheel set shifting swing arm. A swing arm drive motor is provided at the hinge joint between the swing arm and the swing arm of the cleaning wheel assembly; the front end of the swing arm of the cleaning wheel assembly is fixedly connected to the connecting shaft of the cleaning wheel assembly, and several sets of rust removal cleaning wheels are provided on the connecting shaft of the cleaning wheel assembly; and wheel assembly shaft locking parts are provided at both ends of the connecting shaft of the cleaning wheel assembly, and the wheel assembly shaft locking parts at both ends of the connecting shaft of the cleaning wheel assembly are respectively connected to the shaft end locking groove of the cleaning wheel assembly shaft end locking seat rotatably provided on the transmission bearing seat of the cleaning wheel assembly on both sides. The first and second rust-removing cleaning wheelsets are respectively arranged above the cleaning wheel group drive bearing seats on both sides by means of a cleaning wheel group suspension shaft. The swing arm drive motor and the swing arm drive motor are used to drive the cleaning wheel group displacement swing arm and the cleaning wheel group displacement swing arm to extend or retract in coordination. Then, according to the cleaning needs, the two ends of the cleaning wheel group connecting shaft of the first or second rust-removing cleaning wheel group are connected to the cleaning wheel group shaft end locking seats on the cleaning wheel group drive bearing seats on both sides below. This allows the rust-removing cleaning motor to drive the cleaning wheel group connecting shaft to rotate through the rust-removing cleaning transmission pulley and rust-removing cleaning transmission belt set at its output end, thereby driving the rust-removing cleaning wheel group to rotate.

[0009] The rust-removing cleaning wheels connected to the rotating shaft of the cleaning wheel assembly include abrasive belt cleaning wheels, high-hardness steel wire wheels, low-hardness steel wire wheels, and titanium alloy wire wheels. By using the abrasive belt cleaning wheels, high-hardness steel wire wheels, low-hardness steel wire wheels, and titanium alloy wire wheels arranged in a specific order on the rotating shaft of the cleaning wheel assembly, contaminants on the surface of the rotating ingot workpiece are cleaned layer by layer.

[0010] The rust removal and cleaning mechanism on the lifting platform is equipped with a flip-up protective cover. This cover is rotatably connected to one side of the top opening of the lifting platform via a hinge, and the other side is connected to the top opening via a locking mechanism. The cover also has a handle. This flip-up protective cover on the lifting platform, which can be flexibly opened and closed, facilitates the maintenance and replacement of the various sets of rust removal and cleaning wheels on the rust removal and cleaning mechanism, which are arranged facing the interior of the enclosed cleaning chamber, making it convenient to use.

[0011] The enclosed cleaning chamber is also equipped with a dust removal mechanism, which includes a dust discharge connector. The dust discharge connector has a dust discharge isolation sleeve inside. The dust discharge port on the side wall of the dust discharge connector is connected to the dust suction port on the top of the lifting platform via a flexible suction pipe. One end of the dust discharge connector has a dust collection chamber with a discharge port at its lower end. The other end of the dust discharge connector is connected to the air inlet of the suction and air supply impeller chamber via a suction pipe, and the end of the suction pipe is connected to the dust discharge isolation sleeve inside the dust discharge connector. A suction and air supply impeller is rotatably mounted inside the suction and air supply impeller chamber. The shaft of the suction and air supply impeller is connected to the output end of a suction and air supply motor located outside the suction and air supply impeller chamber. The air outlet of the suction and air supply impeller chamber is connected to an air supply port located at the bottom of the enclosed cleaning chamber via an air supply connection pipe. When the rust removal and cleaning wheel assembly of the rust removal and cleaning mechanism cleans the surface of a section of ingot workpiece inside the closed cleaning box, the dust removal and air supply motor drives the dust removal and air supply impeller in the dust removal and air supply impeller chamber to rotate continuously. This allows the dust generated during the cleaning process to enter the dust collection chamber connected to the end of the dust discharge connector through the flexible dust suction pipe. The dust in the dust collection chamber is periodically collected and discharged from the discharge port of the collection chamber. At the same time, clean airflow enters the dust suction connecting pipe through the dust discharge isolation sleeve inside the dust discharge connecting body. Then, it flows back into the closed cleaning box from the air supply connecting pipe connected to the air outlet of the dust removal and air supply impeller chamber, forming a circulation of dust removal airflow.

[0012] The dust-suction and air-blowing rotary impeller includes a circular rotary impeller connecting base plate. An impeller mounting hole is provided in the center of the rotary impeller connecting base plate. Several sets of arc-shaped impeller blades are evenly arranged at equal angles along the outer circumference of the impeller mounting hole on the rotary impeller connecting base plate. The bottom of each arc-shaped impeller blade is fixedly connected to the rotary impeller connecting base plate, and the top of each arc-shaped impeller blade is fixedly connected to an impeller blade top connecting ring. The dust-suction and air-blowing rotary impeller is mounted on a rotating shaft using the central impeller mounting hole, and is continuously rotated by a dust-suction and air-blowing motor. The several sets of arc-shaped impeller blades arranged between the rotary impeller connecting base plate and the impeller blade top connecting ring create a continuous and stable dust-collecting airflow.

[0013] The discharge end of the machine base and the upper part of the ends of the two sets of spiral rollers are provided with discharge guide slopes. After the two sets of spiral rollers rotate continuously, driving the ingot workpiece to slowly pass through the ingot passage into the closed cleaning box, and the rust removal and cleaning mechanism cleans the surface of the ingot workpiece, the ingot workpiece, which continues to move forward, can enter the transfer process from the discharge guide slope at the end of the machine base under the drive of the two sets of spiral rollers.

[0014] The beneficial effects of this invention are as follows: This invention employs a machine base with two sets of parallel spiral rollers, both ends of which are rotatably connected to the ends of the machine base. The driving ends of the two sets of spiral rollers are connected to the output end of a roller drive motor located at the feed end via a roller transmission mechanism. A closed cleaning box is located in the middle of the machine base, above the spiral rollers. Ingot passages are located on the front and rear sides of the closed cleaning box. A lifting platform is located on the top of the closed cleaning box, and a rust removal and cleaning mechanism is installed on the lifting platform. Therefore, its design is reasonable and its structure is compact. This invention changes the traditional method of manually cleaning the surface of ingots using simple mechanical grinding with pneumatic and electric tools, solving the problem of not being able to thoroughly remove impurities adhering to the surface of ingots, especially impurities inside the pores on the surface of ingots. It also improves the working environment, avoids dust pollution, and increases work efficiency. Moreover, the ingot cleaning equipment can easily and quickly change the rotation speed and grinding intensity of the cleaning wheel, and the rotation speed of the ingot workpiece is adjustable. At the same time, it can accurately determine the grinding time and speed for ingot workpieces with uneven impurity distribution, thereby effectively ensuring the grinding quality of the titanium alloy ingot surface.

Detailed Implementation

[0026] according to Figures 1-10The specific structure of this invention is described in detail. The titanium alloy consumable melting ingot cleaning equipment includes a base 1 at the bottom. Two sets of parallel spiral rollers 4 are rotatably mounted on the base 1 for continuously conveying ingot workpieces 11 forward. The axes of the spiral rollers 4 are arranged along the moving direction of the ingot workpieces 11, and both ends of the spiral rollers 4 are rotatably connected to the ends of the base 1. Simultaneously, the drive end sprockets of the two sets of spiral rollers 4 are connected to the output end sprockets of the roller drive motor 5 located at the feed end 2 of the base 1 via roller drive chains. Above the discharge end of the base 1 and the ends of the two sets of spiral rollers 4, a discharge guide slope 3 is provided. After the two sets of spiral rollers 4 continuously rotate, driving the ingot workpieces 11 to slowly pass through the ingot passage 16 and through the closed cleaning box 7, and the rust removal and cleaning mechanism 9 to clean the surface of the ingot workpieces 11, the ingot workpieces 11, continuing to move forward, can enter the subsequent transfer process from the discharge guide slope 3 at the end of the base 1 under the drive of the two sets of spiral rollers 4.

[0027] A closed cleaning chamber 7 is provided in the middle of the base 1, above the spiral roller shaft 4, to prevent dust pollution to the environment. On the front and rear sides of the closed cleaning chamber 7 along the axial direction of the spiral roller shaft 4, there are ingot passage openings 16. Furthermore, a flexible rubber sealing ring, adaptable to different workpiece diameters, is provided between the ingot passage opening 16 and the outer wall of the ingot workpiece 11. A lifting platform 8 is provided on the top of the closed cleaning chamber 7, and an observation window 12 is provided on the lifting platform 8. Platform lifting guide posts 25 are provided on the lower side of the four corners of the lifting platform 8. The lifting platform 8 is movably mounted in the platform lifting guide grooves 38 on the outer wall of the closed cleaning chamber 7 via the platform lifting guide posts 25. Simultaneously, telescopic folding sealing mechanisms 15 are provided between the lifting platform 8 and the top of the four sides of the closed cleaning chamber 7.

[0028] A platform lifting mechanism 13 is also provided between the lifting platform 8 and the enclosed cleaning box 7. The platform lifting mechanism 13 includes two sets of platform lifting guide worm gears 14 fixedly installed on the upper part of the enclosed cleaning box 7 and on both sides of the flip-up protective cover 17. The vertically arranged platform lifting guide worm gears 14 mesh with the platform lifting transmission worm wheel 27 rotatably installed on the lifting platform 8, and the rotation shaft of the platform lifting transmission worm wheel 27 is connected to the output end of the platform lifting drive motor 26. Then, the platform lifting mechanism 13 is driven by the platform lifting drive motor 26. That is, through the cooperation of the platform lifting transmission worm wheel 27 and the vertically arranged platform lifting guide worm gears 14, the lifting platform 8 is driven to reciprocate up and down on the top of the enclosed cleaning box 7 by means of the cooperation of the platform lifting guide pin 25 and the platform lifting guide groove 38. This allows the rust removal and cleaning mechanism 9 arranged on the lifting platform 8 to adapt to casting workpieces 11 of different diameters.

[0029] The lifting platform 8 is equipped with a rust removal and cleaning mechanism 9 facing the interior of the enclosed cleaning chamber 7. The rust removal and cleaning mechanism 9 is also covered by a flip-up protective cover 17. The flip-up protective cover 17 is rotatably connected to one side of the top opening of the lifting platform 8 via a protective cover hinge 28, and is connected to the other side of the top opening of the lifting platform 8 via a locking mechanism. The top of the flip-up protective cover 17 is equipped with a suction port 29 for connecting to a flexible suction pipe 18, and a protective cover handle 30 is also provided on the flip-up protective cover 17. Thus, the flip-up protective cover 17 on the lifting platform 8, which can be flexibly opened and closed, facilitates the maintenance and replacement of the various sets of rust removal and cleaning wheels on the rust removal and cleaning mechanism 9 facing the interior of the enclosed cleaning chamber 7, making it convenient to use.

[0030] The rust removal and cleaning mechanism 9 includes a rust removal and cleaning wheel assembly, which consists of a first rust removal and cleaning wheel assembly 41 and a second rust removal and cleaning wheel assembly 42 movably arranged above the cleaning wheel assembly drive bearing seat 43. The first rust removal and cleaning wheel assembly 41 and the second rust removal and cleaning wheel assembly 42 have the same structure, both including a cleaning wheel assembly suspension shaft 45. Two sets of cleaning wheel assembly shifting swing arms 47 are fixedly mounted on the cleaning wheel assembly suspension shaft 45. The drive end of the cleaning wheel assembly suspension shaft 45 is connected to the output end of the swing arm drive motor 46. The front end of the cleaning wheel assembly shifting swing arm 47 is also hinged to a cleaning wheel assembly shifting swing arm 48. The hinge part between the cleaning wheel assembly shifting swing arm 48 and the cleaning wheel assembly shifting swing arm 47 is provided with a swing arm drive motor 49. At the same time, the front end of the cleaning wheel assembly shifting swing arm 48 is fixedly connected to the cleaning wheel assembly connecting shaft 50, and several sets of rust removal and cleaning wheels are mounted on the cleaning wheel assembly connecting shaft 50. Several sets of rust-removing cleaning wheels can be used in any combination of two, three, or four of the following: abrasive belt cleaning wheels 55, high-hardness steel wire wheels 56, low-hardness steel wire wheels 57, and titanium alloy wire wheels 58. This allows for the layer-by-layer cleaning of contaminants on the surface of the rotating ingot workpiece 11 by using the abrasive belt cleaning wheels 55, high-hardness steel wire wheels 56, low-hardness steel wire wheels 57, and titanium alloy wire wheels 58 arranged in a specific order on the cleaning wheel assembly connecting shaft 50. It is understood that, depending on specific usage needs and with sufficient arrangement space, the driving method for the cleaning wheel assembly shifting swing arm 47 and the cleaning wheel assembly shifting swing arm 48 can also employ hydraulic or pneumatic telescopic rod structures.

[0031] Furthermore, the cleaning wheel assembly connecting shaft 50 of the rust removal and cleaning mechanism 9 is provided with wheel assembly shaft locking parts 54 at both ends. The wheel assembly shaft locking parts 54 at both ends of the cleaning wheel assembly connecting shaft 50 are respectively connected to the shaft end locking grooves 53 of the two sets of cleaning wheel assembly transmission bearing seats 43 fixedly installed on the top of the enclosed cleaning box 7 and rotatably installed on the cleaning wheel assembly shaft end locking seats 44. The drive end of the connecting shaft on one set of cleaning wheel assembly transmission bearing seats 43 is also connected to the output end of the rust removal and cleaning motor 39 through the rust removal and cleaning transmission mechanism 40 composed of the rust removal and cleaning transmission pulley 52 and the rust removal and cleaning transmission belt 51. Thus, the first rust-removing cleaning wheel set 41 and the second rust-removing cleaning wheel set 42 are respectively arranged above the cleaning wheel set transmission bearing seats 43 on both sides by the cleaning wheel set suspension shaft 45. The swing arm drive motor 46 and the swing arm drive motor 49 are used to drive the cleaning wheel set displacement swing arm 47 and the cleaning wheel set displacement swing arm 48 to extend or retract in coordination. Then, according to the cleaning processing needs, the two ends of the cleaning wheel set connecting shaft 50 of the first rust-removing cleaning wheel set 41 or the second rust-removing cleaning wheel set 42 are connected to the cleaning wheel set shaft end locking seats 44 on the cleaning wheel set transmission bearing seats 43 on both sides below it. This allows the rust-removing cleaning motor 39 to drive the cleaning wheel set connecting shaft 50 to rotate through the rust-removing cleaning transmission pulley 52 and the rust-removing cleaning transmission belt 51 set at its output end, thereby driving the rust-removing cleaning wheel set to rotate continuously and cleaning the surface contaminants of the ingot workpiece 11 that rotates forward with the rotation of the two sets of spiral roller shafts 4.

[0032] In addition, a dust removal mechanism 10 is provided on the side of the enclosed cleaning box 7. The dust removal mechanism 10 includes a cylindrical dust discharge connector 19, and a dust discharge isolation sleeve 32 is provided inside the dust discharge connector 19. The dust discharge connection port on the side wall of the dust discharge connector 19 is connected to the dust suction connection port 29 on the flip-up protective cover 17 on the top of the lifting platform 8 through a flexible dust suction pipe 18. One end of the cylindrical dust discharge connector 19 is provided with a dust collection chamber 24, and the lower end of the dust collection chamber 24 is provided with a collection chamber discharge port 31. The other end of the cylindrical dust discharge connector 19 is connected to the air inlet of the dust suction and air supply impeller chamber 21 through a U-shaped dust suction connection pipe 20, and the end of the dust suction connection pipe 20 is connected to the dust discharge isolation sleeve 32 inside the dust discharge connector 19. Furthermore, a suction and air supply impeller 33 is rotatably installed inside the suction and air supply impeller chamber 21, and the shaft of the suction and air supply impeller 33 is connected to the output end of the suction and air supply motor 22 installed outside the suction and air supply impeller chamber 21. The air outlet of the suction and air supply impeller chamber 21 is connected to the air outlet provided at the lower part of the enclosed cleaning box 7 through the air supply connecting pipe 23. Thus, when the rust removal and cleaning wheel assembly of the rust removal and cleaning mechanism 9 cleans the surface of a section of ingot workpiece 11 inside the closed cleaning box 7, the dust removal and air supply motor 22 drives the dust removal and air supply impeller 33 in the dust removal and air supply impeller chamber 21 to rotate continuously. This allows the dust generated during the cleaning process to enter the dust collection chamber 24 connected to the end of the dust discharge connector 19 through the flexible dust suction pipe 18, and the dust in the dust collection chamber 24 is periodically collected and discharged from the collection chamber discharge port 31. At the same time, the clean airflow enters the dust suction connecting pipe 20 through the dust discharge isolation sleeve 32 inside the dust discharge connector 19, and then flows back into the closed cleaning box 7 from the air supply connecting pipe 23 connected to the air outlet of the dust removal and air supply impeller chamber 21, forming a circulation of dust removal airflow.

[0033] The dust-suction and air-suction rotary impeller 33, which is rotatably installed inside the dust-suction and air-suction impeller chamber 21, includes a circular rotary impeller connecting base plate 34. The rotary impeller connecting base plate 34 has an impeller mounting hole 37 in the middle. Several sets of arc-shaped impeller blades 35 are evenly arranged on the rotary impeller connecting base plate 34 at equal angles along the outer circumference of the impeller mounting hole 37. The bottom of each arc-shaped impeller blade 35 is fixedly connected to the rotary impeller connecting base plate 34, and the top of each arc-shaped impeller blade 35 is fixedly connected to the impeller blade top connecting ring 36. The dust-suction and air-suction rotary impeller 33 is then installed on the rotating shaft through the impeller mounting hole 37 in the middle. The dust-suction and air-suction motor 22 drives the dust-suction and air-suction rotary impeller 33 to rotate continuously. The several sets of arc-shaped impeller blades 35 arranged between the rotary impeller connecting base plate 34 and the impeller blade top connecting ring 36 form a continuous and stable dust-removing airflow.

[0034] When using this titanium alloy consumable melting ingot cleaning equipment, firstly, according to the grinding treatment method required for the ingot workpiece 11, sand belt cleaning wheels 55, high-hardness steel wire wheels 56, low-hardness steel wire wheels 57, and titanium alloy wire wheels 58 are arranged in a certain order on the cleaning wheel connecting shaft 50 of the first rust removal cleaning wheel group 41 and the second rust removal cleaning wheel group 42 of the rust removal cleaning mechanism 9. The flip-up protective cover 17 set in the middle of the lifting platform 8 is closed (the dust suction connection port 29 of the flip-up protective cover 17 is always connected to the flexible dust suction pipe 18 of the dust removal mechanism 10) so as to clean the contaminants on the surface of the rotating ingot workpiece 11 layer by layer according to the grinding process.

[0035] Then, the ingot workpiece 11 is hoisted onto the feed end 2 of the machine base 1 and onto the two sets of spiral rollers 4. The continuous rotation of the two sets of spiral rollers 4 drives the ingot workpiece 11 to slowly move towards the ingot passage 16 of the closed cleaning box 7. At the same time, the auxiliary scanning component set on the ingot cleaning equipment is used to perform a comprehensive scan of the diameter, length, and surface roughness of the ingot workpiece 11. Then, based on the scan analysis results, the platform lifting drive motor 26 is used to drive the platform lifting mechanism 13 to move, thereby driving the lifting platform 8 to rise and fall and adjust its height at the top of the closed cleaning box 7, so that the rust removal cleaning mechanism 9 arranged on the lifting platform 8 can adapt to the diameter of the ingot workpiece 11 to be polished. Furthermore, the rust removal cleaning wheel set of the rust removal cleaning mechanism 9 is intelligently selected according to the amount of deposits on different parts of the surface of the ingot workpiece 11, that is, the first rust removal cleaning wheel set 41 or the second rust removal cleaning wheel set 42 is selected. In addition, the rotation speed of the rust removal cleaning wheel set and the speed of rotation and horizontal movement of the ingot workpiece 11 are determined by numerical control. Thus, as the two sets of spiral rollers 4 drive the ingot workpiece 11 to slowly pass through the ingot passage 16 into the closed cleaning box 7, the rust removal cleaning motor 39 of the rust removal cleaning mechanism 9 drives the first rust removal cleaning wheel set 41 (or the second rust removal cleaning wheel set 42) to rotate continuously, cleaning the surface contaminants of the ingot workpiece 11.

[0036] Furthermore, when the rust removal and cleaning wheel assembly of the rust removal and cleaning mechanism 9 cleans the surface of a section of the ingot workpiece 11 inside the enclosed cleaning chamber 7, the dust extraction and air supply motor 22 drives the dust extraction and air supply impeller 33 inside the dust extraction and air supply impeller chamber 21 to rotate continuously. This allows the dust generated during the cleaning process to enter the dust collection chamber 24 connected to the end of the dust discharge connector 19 through the flexible dust extraction pipe 18, effectively improving the working environment and preventing dust pollution. At the same time, clean airflow enters the dust extraction connecting pipe 20 through the dust discharge isolation sleeve 32 inside the dust discharge connector 19, and then flows back into the enclosed cleaning chamber 7 from the air supply connecting pipe 23 connected to the air outlet of the dust extraction and air supply impeller chamber 21, forming an effective circulation of dust removal airflow. After the first cleaning is completed, the cleaning effect can be judged by scanning the ingot workpiece 11 again, and the cleaning can be repeated until the cleanliness of the ingot surface meets the technical requirements. Subsequently, the two sets of spiral rollers 4 rotate continuously, driving the surface-cleaned ingot workpiece 11 to slowly pass through the enclosed cleaning box 7 via the ingot passage 16, and continue to move towards the discharge end of the machine base 1. Finally, the ingot workpiece 11 is automatically discharged from the discharge guide slope 3 at the end of the machine base 1. Afterwards, the cleaning quality of the ingot workpiece 11 is checked to ensure that there are no contaminants and no residual cleaning materials. Then, the ingot workpiece 11 is hoisted from the ingot cleaning equipment to the vacuum consumable melting furnace for later use.
