Description

Technical Field

[0001] The invention belongs to the technical field of pipeline cleaning, in particular to a single crystal furnace pipeline cleaning device. Background Art

[0002] The single crystal furnace piping system usually includes exhaust pipes, vacuum devices (such as dry pumps and hoses), leakage detection devices and other components. The exhaust pipe system realizes the vacuum function by exhausting the gas in the single crystal furnace, and the vacuum power can be adjusted by adjusting the dry pump power frequency, thereby improving the accuracy and efficiency of vacuum. In addition, a temperature alarm is installed on the exhaust pipe to monitor the temperature in the exhaust pipe and the leakage of silicon liquid.

[0003] The single crystal furnace pipe cleaning device is a device used to clean the pipes in the single crystal furnace. Its main purpose is to remove volatiles, dust and other impurities deposited in the pipes to ensure the normal operation of the single crystal furnace and improve product quality.

[0004] During the shutdown and dismantling of the single crystal furnace, the accumulation of oxides will block the exhaust port at the connection between the main vacuum pipe and the furnace bottom plate, affecting the vacuum during the crystal pulling process. The prior art uses a swinging cylinder to perform a swinging motion to clean the oxides. However, since the cleaning action needs to extend into the furnace chamber, the high temperature caused by the thermal field during the crystal pulling process will damage the pipe cleaning device and affect its service life. In addition, the single linear motion of the prior art is not comprehensive for cleaning the long-accumulated oxides and has low efficiency. At the same time, the prior art requires the use of more high-temperature materials and has a high cost.

[0005] To this end, the present invention provides a single crystal furnace pipeline cleaning device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a single crystal furnace pipeline cleaning device described in the present invention comprises a sealing ring tube, the sealing ring tube is fixedly installed just below the top of the pipeline, a frame plate is fixedly installed at the bottom of the sealing ring tube, a rotating cylinder is fixedly installed at the bottom of the frame plate, a telescopic cylinder is rotatably connected inside the frame plate, the output end of the rotating cylinder is fixedly connected to the bottom of the telescopic cylinder, a transfer rod is fixedly installed at the output end of the telescopic cylinder, an isolation disk is fixedly installed on the outer wall of the transfer rod, the outer wall of the isolation disk is rotatably connected to the inner wall of the sealing ring tube, a dematerialization box is fixedly installed on the top of the transfer rod, and the top of the dematerialization box is fixedly installed A ring box is provided, a plurality of crushed material boxes are arranged on the top of the ring box, a cleaning knife is arranged outside each of the crushed material boxes, a slag removal mechanism is arranged inside the crushed material box, the slag removal mechanism includes a vacuum dust collector, the slag removal mechanism is used to drive the vacuum dust collector to collect and transport the oxides cleaned by the cleaning knife out of the pipeline, a distance balance mechanism is arranged inside the ring box, the distance balance mechanism includes an axle rod, the distance balance mechanism is used to drive the axle rod to measure the distance of the pipeline, so that the cleaning knife is close to the pipeline while keeping a certain distance between the device and the pipe wall of the pipeline, and a crushing component is arranged inside each of the crushed material boxes, the crushing component is used to crush the oxides cleaned by the cleaning knife; When the oxide in the pipeline needs to be cleaned, the removal box is moved to the bottom of the pipe mouth that needs to be cleaned by driving the telescopic cylinder. At this time, the slag removal mechanism is driven to drive the vacuum dust collector to operate, and then the telescopic cylinder is continued to be driven to make the removal box continue to move upward. When moving upward, the cleaning knife on the top of the ring box breaks the oxide layer in the pipe mouth. When the oxide layer is broken, the driving distance balance mechanism drives multiple debris boxes and cleaning knives to move, so that the cleaning knives fit the inner wall of the pipe mouth. At the same time, the distance balance mechanism ensures that multiple debris boxes are always placed below the side of the cleaning knife, so that the debris box and the pipe mouth maintain a certain distance. When the adjustment of the two is completed, the driving rotary cylinder drives the removal box to rotate through the indexing rod, so that the cleaning knife scrapes and cleans the inner wall of the pipe mouth. When the oxides are scraped and cleaned and fall down, they will enter the debris box under the action of the vacuum cleaner. The debris components in the debris box will crush the oxides entering the debris box, and finally they will be discharged to the outside of the device through the slag removal mechanism. The inner wall of the pipe mouth is rotated and scraped by multiple cleaning knives to speed up the cleaning efficiency. The distance balance mechanism is used to keep the device at a distance from the inner wall of the pipe mouth at all times, which can prevent the high temperature caused by the thermal field from damaging the pipeline cleaning device during the crystal pulling process and affecting its service life. The safety of the device can be greatly guaranteed. The cleaned oxides are transported out of the pipeline through the slag removal mechanism to prevent the oxides from falling into the pipeline and causing accumulation to affect the crystal pulling effect.

When the inner wall of the pipe mouth needs to be cleaned, the rectangular plate is driven to rotate by driving the counter-distance motor. When the rectangular plate rotates, it drives the hinged rod to rotate, thereby pushing the sliding shaft to slide in the rectangular box. When the sliding shaft moves, it drives the debris box to move on the top of the ring box, thereby driving the cleaning knife to fit the inner wall of the pipe mouth, which is convenient for subsequent scraping of oxides in the pipe mouth. By moving and adjusting the position of multiple cleaning knives, the device can be suitable for pipe mouths of different diameters and play a role of adapting to pipes of different diameters.

When the touch rods touch the inner wall of the pipe mouth, the touch rods are subjected to a reverse thrust and will squeeze the pressure springs to move in the opposite direction. When the control button on the end face of the shaft touches the inner wall of the pipe mouth, the touch rods stop moving to prevent the shafts from being exposed to the outside of the device.

When the same-position block moves outward, it pushes the card block to squeeze the return block spring to move upward in the limited slide box, thereby driving the push block to slide out from the inner wall of the correction slide plate. When the push block completes sliding out of the correction slide plate, the push block will lose the limiting blocking force of the sliding shaft. Under the action of the elastic force of the reset spring, the push block will slide from one end of the correction slide plate to the other end, thereby driving the shaft rod and the contact rod to reset, playing the role of resetting the shaft rod. By resetting and adjusting the cleaning knife, the device can maintain a certain distance from the inner wall of the pipe mouth, preventing high temperature from eroding the device and improving the safety of the device.

When the cleaning knife rotates to clean the pipe mouth, the crushed oxides are extracted by a vacuum cleaner and the oxides enter the crushing box. At this time, the knife-driving motor is driven to drive the slag crushing knife to rotate, so that the oxides can be broken into small particles, and then they will enter the slag removal mechanism through the isolation plate under the extraction of the vacuum cleaner, so as to prevent the oxide particles from being too large to enter the slag removal mechanism.

Under the action of the elastic force of the reset spring, the push block will slide back to the other end of the correction slide plate from one end, thereby driving the shaft rod and the contact rod to reset. By resetting and adjusting the cleaning knife, the device can maintain a certain distance from the inner wall of the pipe mouth, preventing high temperature from eroding the device and improving the safety of the device.

[0018] 2. The single crystal furnace pipeline cleaning device described in the present invention drives the sliding shaft to reset through the balance motor, and the sliding shaft will drive the gear rod 1 to move through the connecting rod. When the gear rod 1 moves, it drives the gear rod 2 to move by the meshing drive gear. When the sliding shaft moves, the gear rod 2 moves to one side of the isostatic block. When the sliding shaft completes the reset, the complex block on the top of the gear rod 2 squeezes the isostatic block, so that the isostatic block pushes the push block to squeeze the card block back into the calibration slide plate, which plays the role of resetting the push block and is convenient for the next calibration operation.

[0019] 3. The single crystal furnace pipeline cleaning device described in the present invention, when the oxide is broken into small particles, the oxide will enter the air flow hose from the top of the sliding shaft at the bottom of the crushing box through the pulling of the vacuum dust collector, and finally flow into the exhaust pipe through the vertical pipe.

When the slag feeding blades rotate, they can transmit and discharge the oxidized slag flowing in from the slag sliding pipe. The discharged oxidized slag can finally pass through the slag sliding boss and flow out of the pipeline from the slag discharge port, thereby playing the role of slag discharge.

[0020] 4. The single crystal furnace pipeline cleaning device described in the present invention drives the counter-distance motor to drive the rectangular plate to rotate. When the rectangular plate rotates, it drives the hinged rod to rotate, thereby pushing the sliding shaft to slide in the rectangular box. When the sliding shaft moves, it drives the debris box to move on the top of the ring box, thereby driving the cleaning knife to fit the inner wall of the pipe mouth, which is convenient for the subsequent scraping of oxides in the pipe mouth.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figures 1 to 14As shown, a single crystal furnace pipeline cleaning device described in an embodiment of the present invention includes a sealing ring tube 1, which is fixedly installed just below the top of the pipeline, a frame plate 101 is fixedly installed on the bottom of the sealing ring tube 1, a rotating cylinder 5 is fixedly installed on the bottom end of the frame plate 101, a telescopic cylinder 3 is rotatably connected inside the frame plate 101, an output end of the rotating cylinder 5 is fixedly connected to the bottom of the telescopic cylinder 3, an indexing rod 4 is fixedly installed on the output end of the telescopic cylinder 3, an isolation disk 102 is fixedly installed on the outer wall of the indexing rod 4, an outer wall of the isolation disk 102 is rotatably connected to the inner wall of the sealing ring tube 1, a dematerialization box 2 is fixedly installed on the top of the indexing rod 4, and a ring is fixedly installed on the top of the dematerialization box 2. Box 9, a plurality of crushing boxes 6 are arranged on the top of the ring box 9, and a cleaning knife 8 is arranged outside the plurality of crushing boxes 6. A slag removal mechanism is arranged inside the crushing box 2, and the slag removal mechanism includes a vacuum dust collector 201, and the slag removal mechanism is used to drive the vacuum dust collector 201 to collect and transport the oxides cleaned by the cleaning knife 8 out of the pipeline. A distance balance mechanism is arranged inside the ring box 9, and the distance balance mechanism includes a shaft rod 76, and the distance balance mechanism is used to drive the shaft rod 76 to measure the distance of the pipeline, so that the cleaning knife 8 is close to the pipeline and the device is kept at a certain distance from the pipe wall of the pipeline. A plurality of crushing boxes 6 are arranged inside, and a crushing assembly is arranged, and the crushing assembly is used to crush the oxides cleaned by the cleaning knife 8; During the shutdown and dismantling of the single crystal furnace, the accumulation of oxides will block the exhaust port where the main vacuum pipe connects to the furnace chassis, affecting the vacuum during the crystal pulling process; When the oxide in the pipeline needs to be cleaned, the removal box 2 is moved to the position directly below the pipe opening that needs to be cleaned by driving the telescopic cylinder 3. At the same time, the isolation plate 102 is driven by the indexing rod 4 to move upward from the bottom of the inner wall of the sealing ring tube 1. At this time, the slag removal mechanism is driven to drive the vacuum dust collector 201 to operate, and then the telescopic cylinder 3 is continued to be driven to make the removal box 2 continue to move upward. When moving upward, the cleaning knife 8 on the top of the ring box 9 breaks the oxide layer in the pipe opening. At this time, the isolation plate 102 moves to the top of the inner wall of the sealing ring tube 1. When the oxide layer is broken, , the balancing mechanism is driven to move the multiple debris boxes 6 and the cleaning knife 8, so that the cleaning knife 8 fits the inner wall of the pipe mouth. At the same time, the balancing mechanism ensures that the multiple debris boxes 6 are always placed below the side of the cleaning knife 8, so that the debris boxes 6 maintain a certain distance from the pipe mouth. When the two are adjusted, the rotating cylinder 5 is driven to rotate the removal box 2 through the indexing rod 4, so that the cleaning knife 8 scrapes and cleans the inner wall of the pipe mouth. When the oxide is scraped and cleaned and falls down, the oxide will enter the debris box 6 under the pumping of the vacuum cleaner 201. The crushing component in the crushing box 6 crushes the oxides entering the crushing box 6, and finally discharges them to the outside of the device through the slag removal mechanism.

When part of the oxide is crushed, the oxide will fall on the top of the isolation plate 102. The indexing rod 4 drives the isolation plate 102 to rotate so that the fallen oxide can be thrown to the tail end of the pipeline to prevent the oxide from falling into the sealing ring tube 1 and causing accumulation. The inner wall of the pipe mouth is rotated and scraped by multiple cleaning knives 8 to clean the inner wall of the pipe mouth, which can solve the problem of incomplete and low efficiency of cleaning the long-accumulated oxides by a single linear motion in the prior art, and can speed up the cleaning efficiency. The distance-balancing mechanism is used to keep a distance between the device and the inner wall of the pipe mouth at all times, which can prevent the high temperature caused by the thermal field from damaging the pipeline cleaning device during the crystal pulling process and affecting its service life. The safety of the device can be greatly guaranteed. The cleaned oxide is transported out of the pipeline by the slag removal mechanism to prevent the oxide from falling into the pipeline and causing accumulation that affects the crystal pulling effect.

When the square plate 10 rotates, it drives the hinged rod 11 to rotate, thereby pushing the sliding shaft 12 to slide in the square box 7. When the sliding shaft 12 moves, it drives the debris box 6 to move on the top of the ring box 9, thereby driving the cleaning knife 8 to fit the inner wall of the pipe mouth, so as to facilitate the subsequent scraping of the oxide in the pipe mouth.

At this time, the cleaning knife 8 is attached to the inner wall of the pipe mouth, and the debris box 6 is placed on the lower side of the cleaning knife 8, which plays a role in adjusting the position of the cleaning knife 8.

[0029] like Figure 6 to Figure 7As shown, the outer walls of the two shafts 76 are fixedly mounted with a square block 7103, the outer walls of the other ends of the two shafts 76 are slidably connected with the contact rods 71, the outer walls of the two contact rods 71 ​​are fixedly mounted with a squeeze block 7101, and a pressure spring 7102 is arranged between one end of the two contact rods 71 ​​and one side of the two square blocks 7103, and the pressure spring 7102 is placed outside the shaft 76; When the shaft rod 76 moves, the shaft rod 76 drives the contact rod 71 to move. When the contact rod 71 contacts the inner wall of the pipe mouth, the contact rod 71 is subjected to a reverse thrust and squeezes the pressure spring 7102 to move in the opposite direction. When the control button 77 on the end face of the shaft rod 76 contacts the inner wall of the pipe mouth, the contact rod 71 stops moving to prevent the shaft rod 76 from being exposed to the outside of the device. During the crystal pulling process, the high temperature brought by the thermal field will damage the shaft rod 76, thereby protecting the shaft rod 76. It should be noted here that the contact rod 71 and the control button 77 should be made of high temperature resistant materials.

[0030] like Figures 7 and 8 As shown, the outer walls of the two correction slide plates 73 are fixedly installed with limited sliding boxes 7502, the inner walls of the two limited sliding boxes 7502 are slidably connected with clamping blocks 75, and return springs 7501 are arranged between the tops of the two clamping blocks 75 and the inner walls of the two limited sliding boxes 7502. The inner walls of the two push blocks 74 are symmetrically provided with notches 7401, and one end of the two notches 7401 is fixedly installed with a same-position block 7402. The outer walls of the clamping blocks 75 can be respectively engaged with the inner walls of the two notches 7401, and the two squeezing blocks 7101 can be respectively slidably connected with the inner sides of the two same-position blocks 7402. When the contact rod 71 moves in the opposite direction, the contact rod 71 drives the squeeze block 7101 to move. When the control button 77 contacts the inner wall of the pipe, the contact rod 71 stops moving. At this time, the squeeze block 7101 moves outward by moving the squeeze block 7402. When the squeeze block 7402 moves outward, it pushes the card block 75 to squeeze the return block spring 7501 to move upward in the limited slide box 7502, thereby driving the push block 74 to slide out from the inner wall of the calibration slide plate 73. When the push block 74 completes sliding out of the calibration slide plate 73, the push block 74 will lose the limit resistance of the sliding shaft 12. The blocking force, under the action of the elastic force of the reset spring 7601, the push block 74 will slide back from one end of the correction slide plate 73 to the other end, thereby driving the shaft rod 76 and the contact rod 71 to reset, playing the role of resetting the shaft rod 76, and by resetting and adjusting the cleaning knife 8, the device can maintain a certain distance from the inner wall of the pipe mouth to prevent high temperature from corroding the device and improve the safety of the device. It should be noted here that the safe distance between the device and the pipe mouth needs to be actually measured, and the setting position of the control button 77 should be consistent with the setting position of the cleaning knife 8.

[0031] like Figures 7 to 9As shown, the outer wall of the sliding shaft 12 is symmetrically fixedly installed with a connecting rod 7204, the inner wall of the rectangular box 7 is symmetrically rotatably connected with a gear 72, the inner wall of the rectangular box 7 is symmetrically slidably connected with a gear rod 1 7201 and a gear rod 2 7202, the teeth of the gear 72 can respectively mesh with the teeth on the gear rod 1 7201 and the gear rod 2 7202, the tops of the two gear rods 2 7202 are fixedly installed with a complex block 7203, and the inner walls of the two complex blocks 7203 can respectively be slidably connected with the outer walls of the two isoblocks 7402; When cleaning is completed, the balance motor 13 drives the sliding shaft 12 to reset, and the sliding shaft 12 will drive the gear rod 1 7201 to move through the connecting rod 7204. When the gear rod 1 7201 moves, the meshing driving gear 72 rotates to drive the gear rod 2 7202 to move. When the sliding shaft 12 moves, the gear rod 2 7202 moves to one side of the isotropic block 7402. When the sliding shaft 12 completes the reset, the complex block 7203 on the top of the gear rod 2 7202 squeezes the isotropic block 7402, so that the isotropic block 7402 pushes the push block 74 to squeeze the card block 75 back into the calibration slide plate 73, which plays the role of resetting the push block 74, facilitating the next calibration operation.

[0032] like Figures 3 to 5 As shown, the outer walls of the plurality of debris boxes 6 are fixedly mounted with slot blocks 802, the bottom ends of the plurality of cleaning knives 8 are respectively slidably connected with the inner walls of the plurality of slot blocks 802, a pusher spring 803 is arranged between the bottom ends of the plurality of cleaning knives 8 and the inner walls of the plurality of slot blocks 802, and a ash breaking knife 801 is fixedly mounted on the top of the plurality of cleaning knives 8; When the cleaning knife 8 contacts the inner wall of the pipe mouth, the cleaning knife 8 will squeeze the push knife spring 803 and move back in the groove block 802 through the drive of the sliding shaft 12, so that when the sliding shaft 12 is adjusted for calibration, the cleaning knife 8 can also be adjusted in position in the pipe mouth, thereby ensuring that in pipe mouths of different diameters, the cleaning knife 8 can be adjusted synchronously with the contact rod 71. The ash breaking knife 801 is provided to facilitate the breaking of the oxide layer.

[0033] like Figure 10 to Figure 11 As shown, the shredding assembly includes a knife-driving motor 602, an isolation plate 603 is fixedly installed on the inner wall of the shredding box 6, a knife-driving motor 602 is fixedly installed on the bottom of the isolation plate 603, and a slag-crushing knife 601 is fixedly installed on the output end of the knife-driving motor 602, and the slag-crushing knife 601 is placed on the top of the isolation plate 603; When the cleaning knife 8 rotates to clean the pipe mouth, the broken oxides are extracted by the vacuum cleaner 201 and the oxides enter the debris box 6. At this time, the knife driving motor 602 drives the slag crushing knife 601 to rotate, so that the oxides can be broken into small particles. Then, under the extraction of the vacuum cleaner 201, the oxides enter the slag removal mechanism through the isolation plate 603 to prevent the oxide particles from being too large to enter the slag removal mechanism.

[0034] like Figure 12 to Figure 13 As shown, the slag removal mechanism also includes a vertical pipe 202, and there are multiple vertical pipes 202. The vacuum cleaner 201 is fixedly installed on the inner wall of the de-materialization box 2. The multiple vertical pipes 202 are all fixedly installed with the top of the vacuum cleaner 201. The suction end of the vacuum cleaner 201 is fixedly installed with multiple suction pipes 203. One end of the multiple suction pipes 203 is respectively fixedly connected to one end of the multiple vertical pipes 202. The outer walls of the multiple vertical pipes 202 are all slidably connected with air flow hoses 14. One end of the air flow hose 14 is fixedly connected to the bottom end of the plurality of sliding shafts 12, and a return pipe spring 205 is arranged between the bottom end of the plurality of air flow hoses 14 and the outer wall of the plurality of vertical pipes 202. A slag discharge barrel 207 is fixedly installed in the middle position of the inner wall of the decomposition box 2, and a slag sliding pipe 204 is fixedly installed between the plurality of exhaust pipes 203 and the slag discharge barrel 207. A slag conveying blade 208 is rotatably connected to the inner wall of the slag discharge barrel 207, and a slag filtering port 206 is opened on the inner wall of one end of the plurality of slag sliding pipes 204; When the oxides are broken into small particles, through the pulling of the vacuum dust collector 201, the oxides will enter the air flow hose 14 from the top of the sliding shaft 12 at the bottom of the crushing box 6, and finally flow into the exhaust pipe 203 through the vertical pipe 202. Through the inclined setting of the sliding slag pipe 204, the oxides will enter the slag discharge barrel 207, playing the role of slag conveying. When the sliding shaft 12 moves, the sliding shaft 12 will drive the air flow hose 14 to pull the return pipe spring 205 to slide on the vacuum dust collector 201. When the sliding shaft 12 is reset, the return pipe spring 205 pulls the air flow hose 14 to reset on the vertical pipe 202, playing the role of resetting the air flow hose 14. It should be noted here that the contact end of the air flow hose 14 and the vertical pipe 202 should be provided with a sealing ring, and the setting of the filter residue port 206 is to facilitate the blocking of the oxidized slag to prevent the oxidized slag from entering the interior of the vacuum dust collector 201.

[0035] like Figure 13 to Figure 14 As shown, a rotating rod 209 is fixedly installed on the inner wall of the slag delivery blade 208, a slag delivery motor 18 is fixedly installed inside the indexing rod 4, the output end of the slag delivery motor 18 is fixedly connected to the bottom end of the rotating rod 209, a slag sliding boss 16 is fixedly installed on the inner wall of the indexing rod 4, the slag sliding boss 16 is placed on the top of the circular shaft 15, and a slag outlet 17 is opened on the inner wall of the indexing rod 4; When the rotating cylinder 5 drives the cleaning knife 8 to rotate and remove slag through the indexing rod 4, the slag feeding motor 18 drives the rotating rod 209 to rotate inside the indexing rod 4, thereby driving the slag feeding blade 208 to rotate. When the slag feeding blade 208 rotates, it can transmit and discharge the oxidized slag flowing in from the slag sliding pipe 204. The discharged oxidized slag can finally pass through the slag sliding boss 16 and flow out of the pipeline from the slag outlet 17, thereby playing the role of slag discharge.

[0036] Working principle: when the oxide in the pipeline needs to be cleaned, the removal box 2 is moved to the position directly below the pipe mouth that needs to be cleaned by driving the telescopic cylinder 3. At this time, the slag removal mechanism is driven to drive the vacuum dust collector 201 to operate, and then the telescopic cylinder 3 is continued to be driven to make the removal box 2 continue to move upward. When moving upward, the cleaning knife 8 on the top of the ring box 9 breaks the oxide layer in the pipe mouth. When the oxide layer is broken, the driving distance balance mechanism drives multiple debris boxes 6 and the cleaning knife 8 to move, so that the cleaning knife 8 fits the inner wall of the pipe mouth. At the same time, the distance balance mechanism ensures that multiple debris boxes 6 are always placed below the side of the cleaning knife 8, so that the debris box 6 maintains a certain distance from the pipe mouth. When the adjustment of the two is completed, the driving rotary cylinder 5 drives the removal box 2 to rotate through the indexing rod 4, so that the cleaning knife 8 hits the pipe The inner wall of the pipe mouth is scraped and cleaned. When the oxide falls down after being scraped and cleaned, the oxide will enter the crushing box 6 under the pumping of the vacuum cleaner 201. The crushing component in the crushing box 6 crushes the oxide entering the crushing box 6, and finally discharges it to the outside of the device through the slag removal mechanism. The inner wall of the pipe mouth is rotated and scraped by multiple cleaning knives 8 to speed up the cleaning efficiency. The device is kept at a distance from the inner wall of the pipe mouth by the distance balance mechanism, which can prevent the high temperature caused by the thermal field from damaging the pipeline cleaning device during the crystal pulling process and affecting its service life. The safety of the device can be greatly guaranteed. The cleaned oxide is transported out of the pipeline by the slag removal mechanism to prevent the oxide from falling into the pipeline, causing accumulation and affecting the crystal pulling effect. When the inner wall of the pipe mouth needs to be cleaned, the square plate 10 is driven to rotate by driving the counter-distance motor 13. When the square plate 10 rotates, it drives the hinge rod 11 to rotate, thereby pushing the sliding shaft 12 to slide in the square box 7. When the sliding shaft 12 moves, it drives the debris box 6 to move on the top of the ring box 9, thereby driving the cleaning knife 8 to fit the inner wall of the pipe mouth, which is convenient for scraping the oxide in the pipe mouth later. By moving and adjusting the position of multiple cleaning knives 8, the device can be applied to pipe mouths of different diameters, and plays the role of self-adapting to pipes of different diameters. When the slide shaft 12 moves in the matrix box 7, the slide shaft 12 will push the push block 74 to move in the matrix box 7 through the limit of the calibration slide plate 73. When the push block 74 moves, the push block 74 drives the shaft rod 76 to squeeze the reset spring 7601 to move. When the control button 77 at one end of the shaft rod 76 contacts the inner wall of the pipe, the control button 77 controls the distance control motor 13 to stop driving. At this time, the cleaning knife 8 is attached to the inner wall of the pipe mouth, and the debris box 6 is placed on the side and lower side of the cleaning knife 8, which plays a role in adjusting the position of the cleaning knife 8. When the shaft 76 moves, the shaft 76 drives the contact rod 71 to move. When the contact rod 71 contacts the inner wall of the pipe mouth, the contact rod 71 is subjected to a reverse thrust and squeezes the pressure spring 7102 to move in the opposite direction. When the control button 77 on the end face of the shaft 76 contacts the inner wall of the pipe mouth, the contact rod 71 stops moving to prevent the shaft 76 from being exposed to the outside of the device. During the crystal pulling process, the high temperature caused by the thermal field will damage the shaft 76, which plays a role in protecting the shaft 76. When the locking cam 7502 is in the state of being lifted up, the locking cam 7103 is in the state of being lifted up, and the locking cam 7104 is in the state of being lifted up, so that the locking cam 7103 can be reset when the locking cam 7103 is in the state of being pushed and released. When cleaning is completed, the balance motor 13 drives the sliding shaft 12 to reset, and the sliding shaft 12 will drive the gear rod 1 7201 to move through the connecting rod 7204. When the gear rod 1 7201 moves, it rotates through the meshing driving gear 72 to drive the gear rod 2 7202 to move. When the sliding shaft 12 moves, the gear rod 2 7202 moves to one side of the same position block 7402. When the sliding shaft 12 is reset, the complex block 7203 on the top of the gear rod 2 7202 squeezes the same position block 7402, so that the same position block 7402 pushes the push block 74 to squeeze the card block 75 back into the correction slide plate 73, which plays the role of resetting the push block 74, which is convenient for the next correction operation. When the cleaning knife 8 contacts the inner wall of the pipe mouth, the cleaning knife 8 will squeeze the push knife spring 803 and move back in the slot block 802 through the drive of the sliding shaft 12, so that when the sliding shaft 12 is adjusted, the cleaning knife 8 can also be adjusted in position in the pipe mouth, thereby ensuring that the cleaning knife 8 can be adjusted synchronously with the contact rod 71 in pipe mouths of different diameters. The ash breaking knife 801 is provided to facilitate the breaking of the oxide layer; When the cleaning knife 8 rotates to clean the pipe mouth, the broken oxides are extracted by the vacuum cleaner 201, and the oxides enter the broken object box 6. At this time, the knife driving motor 602 drives the slag breaking knife 601 to rotate, so that the oxides can be broken into small particles, and then the oxides can enter the slag removal mechanism through the isolation plate 603 under the extraction of the vacuum cleaner 201, so as to prevent the oxide particles from being too large to enter the slag removal mechanism. When the oxides are broken into small particles, through the pumping of the vacuum cleaner 201, the oxides will enter the air flow hose 14 from the top of the sliding shaft 12 at the bottom of the crushing box 6, and finally flow into the suction pipe 203 through the vertical pipe 202. Through the inclined setting of the sliding slag pipe 204, the oxides will enter the slag discharge barrel 207, playing the role of slag conveying. When the sliding shaft 12 moves, the sliding shaft 12 will drive the air flow hose 14 to pull the return pipe spring 205 to slide on the vacuum cleaner 201. When the sliding shaft 12 is reset, the return pipe spring 205 pulls the air flow hose 14 to reset on the vertical pipe 202, playing the role of resetting the air flow hose 14. When the rotating cylinder 5 drives the cleaning knife 8 to rotate and remove slag through the indexing rod 4, the slag feeding motor 18 drives the rotating rod 209 to rotate inside the indexing rod 4, thereby driving the slag feeding blade 208 to rotate. When the slag feeding blade 208 rotates, it can transmit and discharge the oxidized slag flowing in from the slag sliding pipe 204. The discharged oxidized slag can finally pass through the slag sliding boss 16 and flow out of the pipeline from the slag outlet 17, thereby playing the role of slag discharge.
