[0001] The present invention relates to a grinding device and a grinding method for quartz tube processing, in particular to a grinding device and a grinding method for quartz tube processing applied to the technical field of grinding devices. Background Art

[0002] During the processing of quartz tubes, the grinding process is an important procedure to ensure the surface finish of quartz tubes. However, existing grinding devices have some problems in actual applications, mainly focusing on grinding efficiency, dust control, and operation convenience.

[0003] For example, Chinese invention patent CN116175299B discloses a dust removal grinding device for quartz tube processing. This device realizes the movement and grinding operation of the grinding motor through the cooperation of an electric slide rail and a hydraulic cylinder. Although this device can collect and remove impurities generated during grinding in a timely manner, in actual applications, its design has the following problems: First, the structure of the device is relatively complex, especially the coupled design of the impurity collection device and the grinding device increases the maintenance difficulty of the equipment; Second, the dust collection efficiency during the grinding process is not ideal enough, and it is easy to cause dust leakage, polluting the operating environment. In addition, this device is mainly for planar grinding and lacks the ability to grind quartz tubes comprehensively.

[0004] Another Chinese invention patent CN117428652B discloses a dust removal grinding device for quartz tube processing. Through the combination of an inner support grinding mechanism, an outer clamp grinding mechanism, and a dust removal mechanism, it realizes the comprehensive grinding of the inner wall, outer wall, and end of the quartz tube. Although this device considers the fine grinding of different parts of the quartz tube in its design, in actual operation, the process of grinding the inner wall, outer wall, and end in sequence by this device is relatively complex, the operation takes a long time, and it is difficult to meet the requirements of high-efficiency production. In addition, the control of dust during the grinding process of this device also has deficiencies. Especially when grinding the end, the dust is easy to spread, increasing the environmental pollution and the health risks of operators.

[0005] Although the above two devices respectively solve some problems in the quartz tube grinding process, there are still certain limitations, such as the complexity of the equipment increases the difficulty of operation and maintenance, the dust treatment effect is not ideal enough, and the overall grinding process is time-consuming.

[0006] Aiming at the problems existing in the above-mentioned prior art, the present invention aims to provide an improved grinding device and a grinding method for quartz tube processing to solve the problems of low grinding efficiency, poor dust control, and complex operation existing in the prior art.

[0008] In the above grinding device and grinding method for quartz tube processing, the boxes, clamping rotating shaft, clamping cylinder and clamping rings symmetrically arranged left and right can stably fix quartz tubes with different diameters, and realize the automatic expansion and fixation of the clamping rings through the action of high-pressure gas, reducing the complexity of manual operation. The dust treatment system of the device effectively improves the dust adsorption and centralized treatment ability through the combined design of a cyclone separation box, a wet adsorption layer and a planetary gear system, avoiding the problems of dust leakage and resuspension. In addition, the freely openable and closable design and the magnetic attraction fixing mechanism of the device further enhance the operation convenience and safety of the equipment.

[0009] As a further improvement of the present application, a cyclone separation box is fixedly connected to the bottom end of the box fixedly connected to the first motor. The top end of the cyclone separation box is a cylindrical structure, and the bottom end is a conical structure, and the end with a smaller diameter of the conical structure is arranged away from the centrifugal impeller. A base is fixedly connected to the outer end of the cyclone separation box.

[0010] As a further improvement of the present application, a wet adsorption layer is clamped inside the cyclone separation box. The top end of the wet adsorption layer is a cylindrical structure, and the bottom end is a conical structure, and the end with a smaller diameter of the conical structure is arranged away from the centrifugal impeller. The wet adsorption layer is made of a water-absorbing material. The distance between the symmetrically arranged boxes and the outer end of the dust removal rotating shaft is three to five centimeters.

[0011] As a further improvement of the present application, the cyclone separation box is of a hollow structure. A plurality of through holes are provided at one end of the cyclone separation box close to the wetting adsorption layer, and the plurality of through holes are all communicated with the hollow part of the cyclone separation box. The hollow part of the cyclone separation box is connected to an external water supply system through a pipeline.

[0012] As another improvement of the present application, a planetary gear box is fixedly connected to the position of the bottom end of the box body inside the wetting adsorption layer. The planetary gear box is provided with a planetary gear train. The sun gear of the planetary gear train is fixedly connected to the outer end of the dust removal rotating shaft. The planetary gears of the planetary gear train are fixedly connected to the planetary gear box. A turntable is fixedly connected to the bottom end of the ring gear of the planetary gear train.

[0013] As a supplement to another improvement of the present application, a first scraper and a second scraper are respectively fixedly connected to the top end and the bottom end of the turntable. The first scraper is arranged corresponding to the cylindrical structure of the wetting adsorption layer, and the second scraper is arranged corresponding to the conical structure of the wetting adsorption layer.

[0014] As a supplement to another improvement of the present application, the second scraper is composed of a plurality of spiral blades, and one ends of the plurality of spiral blades close to each other are fixedly connected through a plurality of rings with different diameters.

[0015] As another improvement of the present application, a dust collection box is fixedly connected to the bottom end of the cyclone separation box, and the dust collection box is connected to an external collection system through a pipeline. A exhaust pipe is fixedly connected to the center of the dust collection box. The top end of the exhaust pipe extends to the top end of the conical structure of the wetting adsorption layer, and the bottom end of the exhaust pipe is connected to an external exhaust system. One end of the symmetrically arranged box body is hinged through a rotating shaft, and the other end can be freely opened and closed. A magnetic suction handle is fixedly connected to the freely opened and closed end. A one-way air inlet valve is fixedly connected to the top end of the box body.

[0016] A method for using a grinding device for processing quartz tubes includes the following steps:

[0017] S1: Open the box body that can rotate freely, slide the clamping rotating shaft upward, put the quartz tube on the outer ends of the clamping cylinder and the clamping ring, and introduce high-pressure gas into the clamping rotating shaft and the clamping cylinder through the air supply system to make the clamping ring expand outwards to clamp and fix the quartz tube.

[0018] S2: Slide the clamping rotating shaft downward to make the bottom end of the clamping cylinder be clamped and fixed to the top end of the dust removal rotating shaft, and then close the box body so that the box bodies are attracted and fixed to each other under the magnetic suction effect.

[0019] S3: Drive the clamping rotating shaft, the clamping cylinder, the clamping ring and the quartz tube to rotate through the first motor, and the grinding head on the grinding head fixing seat grinds the quartz tube. The second motor drives the lead screw to rotate to make the grinding head fixing seat move back and forth along the axis direction of the lead screw.

[0020] S4: During the grinding process, the generated dust is sealed in two boxes. The rotation of the clamping cylinder drives the rotation of the dust removal rotating shaft and the centrifugal impeller. The centrifugal impeller pumps the gas in the box into the inner wall of the wet adsorption layer through centrifugal force, and the dust is adsorbed under the action of centrifugal force and the moisture of the wet adsorption layer.

[0021] S5: The dust adsorbed by the wet adsorption layer is scraped off during the rotation of the first scraper and the second scraper. The second scraper centrally pushes the scraped dust into the dust collection box, and the gas after dust separation is discharged through the exhaust pipe.

[0022] In summary, the present application has the following beneficial effects:

[0023] 1. Efficient and stable fixation and grinding of quartz tubes. The device of this patent realizes the firm fixation of quartz tubes through the coordinated action of the clamping rotating shaft, the clamping cylinder and the clamping ring. In particular, the clamping ring is made of a flexible material and firmly fixes the quartz tube in the device by means of high-pressure gas expansion, ensuring the stability of the quartz tube and the uniformity of grinding during the grinding process. This design is not only applicable to quartz tubes of different specifications, but also greatly improves the grinding efficiency.

[0024] 2. Precise and adjustable grinding process. The first motor and the second motor in the device respectively drive the clamping rotating shaft and the grinding head fixing seat, realizing the rotation of the quartz tube and the linear movement of the grinding head. Through the cooperation of the lead screw and the guide rail, the grinding head can accurately move along the axis direction of the quartz tube, ensuring the uniform grinding of the quartz tube surface. The device design allows precise control of the grinding process to meet the requirements of different processing precisions.

[0025] 3. Efficient dust collection and treatment system. The dust treatment system of the device of this patent adopts multiple measures to ensure that the dust generated during the grinding process is efficiently collected and treated. The centrifugal impeller introduces the dust and gas generated during the grinding process into the cyclone separation box through centrifugal force, and the wet adsorption layer further adsorbs and treats the dust. Through this system, the device can effectively prevent dust leakage and protect the operation environment and the health of personnel.

[0026] 4. The application of the wet adsorption layer improves the dust treatment effect. The design of the wet adsorption layer significantly improves the dust treatment effect. The adsorption layer is made of a water-absorbing material and can effectively adsorb fine dust particles in a wet state, avoiding the secondary suspension of dust in the cyclone separation box. Combined with the scraping functions of the first scraper and the second scraper, the dust can be efficiently removed from the surface of the adsorption layer and centrally collected, reducing the dust accumulation inside the equipment and extending the service life of the device.

[0027] 5. Centralized collection and safe discharge of dust. The design of the dust collection box and exhaust pipe enables the centralized collection and safe discharge of dust. The gas that has undergone cyclone separation and wet adsorption treatment is discharged through the exhaust pipe, further reducing pollution to the external environment. This design not only improves the environmental protection performance of the device but also simplifies the subsequent dust treatment process, facilitating the overall environmental management of the factory.

[0028] 6. Operational convenience and equipment safety. The design of the device's box body takes into account operational convenience and safety. The box body is hinged through a rotating shaft and is designed with a magnetic handle and a one-way intake valve, enabling operators to conveniently load, maintain, and inspect the equipment. At the same time, the sealing design of the box body and the use of the intake valve ensure the airtightness of the equipment, preventing dust leakage and improving the safety of the equipment.

[0029] 7. Dual protection of environmental protection and operator health. The patented device significantly reduces the harm of dust to the environment and operator health through multi-level dust treatment measures. The coordinated action of components such as the wet adsorption layer, cyclone separation box, centrifugal impeller, and dust collection box ensures the efficient collection and treatment of dust. This not only enhances the environmental protection performance of the equipment but also provides a safer and healthier working environment for operators. Description of the Drawings

[0042] The following will describe in detail three embodiments of the present application with reference to the accompanying drawings.

[0043] Embodiment 1

[0044] As Figures 1 to 10 shown, this embodiment provides a basic grinding device for quartz tube processing. The device includes box bodies 1 symmetrically arranged on the left and right. Inside the box body 1, a clamping rotating shaft 2 is connected through a shaft structure. At the bottom end of the clamping rotating shaft 2, a clamping cylinder 3 is fixedly connected. A plurality of clamping rings 4 are clamped on the clamping cylinder 3. These clamping rings 4 are all made of flexible materials and can flexibly adapt to quartz tubes of different diameters. At the positions corresponding to the clamping cylinder 3 and the clamping rings 4, a plurality of through holes are provided for adjusting the expansion and contraction of the clamping rings 4 through air pressure, so as to realize the clamping and fixing of the quartz tube.

[0045] The clamping cylinder 3 is fixed at the top end of the box body 1. At the top end of one of the box bodies 1, a motor 1 5 is fixedly connected to the position of the clamping rotating shaft 2. The power shaft of the motor 1 5 is slidably connected to the clamping rotating shaft 2 along its axis direction to ensure the stability of the clamping rotating shaft 2 during the loading and grinding of the quartz tube. The top end of the clamping rotating shaft 2 passes through the power shaft of the motor 1 5 and extends to the upper side of the motor 1 5. The extended part is connected through an external air supply system. The air supply system can introduce high-pressure gas into the clamping rotating shaft 2 and the clamping cylinder 3, so that the clamping rings 4 expand outwards and firmly fix the quartz tube on the device.

[0046] A guide rail 6 and a lead screw 7 are also arranged inside the box body 1. The guide rail 6 is fixedly connected to the box body 1. Both ends of the lead screw 7 penetrate through the box body 1 and are rotatably connected to the box body 1. At the position corresponding to the lead screw 7 at the outer end of the box body 1, a motor 2 is fixedly connected for driving the rotation of the lead screw 7, so as to drive the grinding head fixing seat 8 to move back and forth along the axis direction of the guide rail 6 to complete the uniform grinding of the quartz tube.

[0047] The bottom end of the grinding head fixing seat 8 is connected to the centrifugal impeller 10 through the dust removal rotating shaft 9. The centrifugal impeller 10 is arranged on the lower side of the box body 1 and penetrates through the entire box body 1 through the dust removal rotating shaft 9, so that during the grinding process, the generated dust is sucked into the cyclone separation box 11 by centrifugal force for preliminary dust separation.

[0048] The cyclone separation box 11 is fixedly connected to the bottom end of the box body 1. The top end of the cyclone separation box 11 is a cylindrical structure, and the bottom end is a conical structure. The end with the smaller diameter of the conical structure is arranged away from the centrifugal impeller 10. A base is fixedly connected to the outer end of the cyclone separation box 11 to maintain the overall stability of the device.

[0049] A dust collection box 18 is also connected to the bottom end of the cyclone separation box 11. The dust collection box 18 is connected to an external collection system through a pipeline for centrally collecting the dust generated during the grinding process. A exhaust pipe 19 is fixedly connected to the center of the dust collection box 18, and the top end of the exhaust pipe 19 extends to the top end of the conical structure of the wetting adsorption layer 12 for discharging the clean gas after dust separation.

[0050] Working process

[0051] When in use, first open the box body 1, put the quartz tube to be ground on the outer ends of the clamping cylinder 3 and the clamping ring 4, and then introduce high-pressure gas into the clamping rotating shaft 2 and the clamping cylinder 3 through the air supply system. Under the action of the air pressure, the plurality of clamping rings 4 expand outwards to firmly fix the quartz tube. After that, start the first motor 5 to drive the clamping rotating shaft 2, the clamping cylinder 3, the clamping ring 4 and the quartz tube to rotate together. At the same time, the second motor drives the lead screw 7 to rotate, and the grinding head fixing seat 8 moves back and forth along the axis direction of the guide rail 6 to complete the grinding of the surface of the quartz tube.

[0052] The dust generated during the grinding process will be sucked into the cyclone separation box 11 by the centrifugal force of the centrifugal impeller 10 for preliminary separation. The larger dust particles settle in the cyclone separation box 11 and finally enter the dust collection box 18, while the gas separated by the cyclone is discharged through the exhaust pipe 19. The dust collection box 18 is connected to an external collection system for safely treating the collected dust.

[0053] The grinding device for processing quartz tubes in this embodiment can adapt to quartz tubes of different specifications through the flexible design of the clamping ring 4 to achieve a stable clamping effect, and improves the operation convenience of the device through air pressure adjustment. Through the coordinated work of the first motor 5 and the second motor, uniform grinding of the quartz tube is achieved, ensuring the quality and efficiency of grinding.

[0054] In addition, the combined use of the centrifugal impeller 10 and the cyclone separation box 11 effectively reduces the dust pollution generated during the grinding process, protects the operating environment and the health of the operators. The design of the dust collection box 18 ensures the centralized treatment of dust, further improving the safety and environmental protection of the device.

[0055] Example 2

[0056] As Figures 1 to 10 shown, on the basis of Example 1, Example 2 further improves and optimizes the dust removal and dust treatment system of the grinding device to improve the dust treatment efficiency and the cleaning performance of the equipment.

[0057] In the grinding device of this embodiment, a wetting adsorption layer 12 is added in the cyclone separation box 11. The top end of the wetting adsorption layer 12 is of a cylindrical structure, and the bottom end is of a conical structure. The end with a smaller diameter of the conical structure is arranged away from the centrifugal impeller 10. This structural design enables the dust to gradually concentrate at the bottom end of the conical structure during the cyclone separation process, thereby improving the dust adsorption efficiency. The wetting adsorption layer 12 is made of a water-absorbing material, which can effectively adsorb and retain moisture, further enhancing the ability to capture dust. The setting of the wetting adsorption layer 12 controls the distance between the symmetrically arranged box body 1 and the outer end of the dust removal rotating shaft 9 within the range of three to five centimeters, which can ensure that the dust is quickly adsorbed under the action of centrifugal force.

[0058] The structure of the cyclone separation box 11 is also optimized. The cyclone separation box 11 is of a hollow structure. A plurality of through holes are opened at one end close to the wetting adsorption layer 12. The through holes are communicated with the hollow part of the cyclone separation box 11. The hollow part of the cyclone separation box 11 is connected to an external water supply system through a pipeline, so that the wetting adsorption layer 12 always remains in a wet state during the entire working process. This design ensures that during the dust adsorption process, the wetting adsorption layer 12 can continuously and effectively adsorb fine dust particles and prevent the dust from re-suspending in the cyclone separation box 11.

[0059] At the bottom end of the box body 1 near the wetting adsorption layer 12, a planetary gear box 13 is also fixedly connected. A planetary gear train 14 is arranged inside the planetary gear box 13. The sun gear of the planetary gear train 14 is fixedly connected to the outer end of the dust removal rotating shaft 9. The planetary gears of the planetary gear train 14 are fixedly connected to the planetary gear box 13. The bottom end of the ring gear of the planetary gear train 14 is fixedly connected with a turntable 15. A first scraper 16 and a second scraper 17 are respectively fixedly connected to the top end and the bottom end of the turntable 15. The first scraper 16 is arranged corresponding to the cylindrical structure of the wetting adsorption layer 12, mainly used for scraping the dust attached to the cylindrical adsorption layer; the second scraper 17 is arranged corresponding to the conical structure of the wetting adsorption layer 12. The second scraper 17 is composed of a plurality of spiral blades, and the ends of the spiral blades close to each other are fixedly connected by a plurality of rings with different diameters. This design can push the scraped dust downward and concentrate it at the bottom end of the cyclone separation box 11, and then collect it through the dust collection box 18.

[0060] For ease of operation and maintenance, one end of the box body 1 is hinged through a rotating shaft, and the other end can be freely opened and closed. A magnetic handle is fixedly connected to the opening and closing end. A one-way intake valve is fixedly connected to the top of the box body 1 to ensure that when the box body 1 is opened, external air will not flow back into the box body 1, thereby maintaining the internal airtightness and negative pressure state.

[0061] Working process

[0062] When using the grinding device in this embodiment, first open the box body 1, put the quartz tube to be ground on the outer ends of the clamping cylinder 3 and the clamping ring 4, and make the clamping ring 4 expand through the air supply system to fix the quartz tube. Then start the first motor 5 to drive the quartz tube to rotate, and at the same time start the second motor to move the grinding head along the lead screw 7 for grinding. During the grinding process, the generated dust is sucked into the cyclone separator 11 under the action of centrifugal force and gradually deposited on the wet adsorption layer 12.

[0063] Since the wet adsorption layer 12 always remains in a wet state, dust particles will be quickly adsorbed when hitting the wet adsorption layer 12, avoiding the resuspension of dust. At the same time, the planetary gear train 14 drives the scraper 16 and the scraper 17 on the turntable 15 to rotate by rotating the dust removal rotating shaft 9, and scrapes off the dust attached to the wet adsorption layer 12. The spiral-structured scraper 17 further concentrates the dust and pushes it into the dust collection box 18 for collection.

[0064] During the whole process, the freely openable and closable design of the box body 1 enables the operator to conveniently open the box body 1 for equipment maintenance and inspection. At the same time, the one-way intake valve ensures the airtightness of the box body 1 and prevents dust from leaking out.

[0065] By adding the wet adsorption layer 12 and optimizing the structure of the cyclone separator 11, the grinding device in this embodiment significantly improves the dust collection and treatment efficiency. The existence of the wet adsorption layer 12 ensures that dust will not be resuspended during the collection process, improving the dust removal effect. The cooperation of the planetary gear train 14 with the scraper 16 and the scraper 17 enables the dust to be effectively scraped off and centrally processed, reducing the dust accumulation inside the equipment and extending the service life of the equipment.

[0066] In addition, the freely openable and closable design of the box body 1 and the setting of the one-way intake valve make the equipment maintenance more convenient, and at the same time further improve the safety and operation convenience of the equipment. Generally speaking, this embodiment improves the grinding efficiency while greatly reducing dust pollution, effectively protecting the environment and the health of operators.

[0067] Embodiment 3

[0068] As Figures 1 to 10As shown, Embodiment 3 is based on Embodiment 1 and Embodiment 2, and details the usage method of the grinding device for quartz tube processing, covering the startup, operation, and dust treatment processes of the device. This method includes the following steps:

[0069] S1: Loading and fixing the quartz tube

[0070] First, the operator opens the box body 1. By sliding the clamping rotating shaft 2 upward, the quartz tube to be ground is sleeved outside the clamping cylinder 3 and the clamping ring 4. Then, high-pressure gas is introduced into the clamping rotating shaft 2 and the clamping cylinder 3 through the air supply system. Under the action of air pressure, multiple clamping rings 4 expand outward, thereby firmly clamping and fixing the quartz tube in the device.

[0071] S2: Positioning and sealing

[0072] After the quartz tube is fixed, the operator slides the clamping rotating shaft 2 downward so that the bottom end of the clamping cylinder 3 is clamped and fixed to the top end of the dust removal rotating shaft 9. Then, the box body 1 is closed. At this time, the box bodies 1 attract each other under the magnetic attraction to form a sealed state, ensuring that dust will not leak during the subsequent grinding process.

[0073] S3: Grinding operation

[0074] The operator starts the first motor 5. The first motor 5 drives the clamping rotating shaft 2, the clamping cylinder 3, the clamping ring 4, and the quartz tube to rotate together. At the same time, the second motor is started to make the grinding head fixing seat 8 move back and forth along the axis of the lead screw 7. The grinding head on the grinding head fixing seat 8 evenly grinds the quartz tube to ensure that the surface of the quartz tube is smooth and flawless.

[0075] S4: Dust collection and treatment

[0076] During the grinding process, the generated dust is sealed in the two box bodies 1. As the clamping cylinder 3 rotates, the dust removal rotating shaft 9 and the centrifugal impeller 10 also start to rotate. The centrifugal impeller 10 sucks the gas in the box body 1 into the inner wall of the wetting adsorption layer 12 through centrifugal force. The dust is effectively adsorbed under the action of centrifugal force and the moisture of the wetting adsorption layer 12, avoiding dust leakage.

[0077] S5: Dust scraping and discharging

[0078] The dust adsorbed by the wetting adsorption layer 12 is scraped off during the rotation of the first scraper 16 and the second scraper 17. Since the second scraper 17 is composed of multiple spiral blades, the scraped dust is pushed downward by the spiral blades during the rotation and finally concentrated in the dust collection box 18 for collection. The gas after dust separation is discharged through the exhaust pipe 19 to ensure the cleanliness of the working environment.

[0079] During use

[0080] Open the rotatable box body 1, then slide the clamping rotating shaft 2 upward. After that, put the quartz tube to be polished onto the outer ends of the clamping cylinder 3 and the clamping ring 4. Then, introduce high-pressure gas into the clamping rotating shaft 2 and the clamping cylinder 3 through the air supply system. Under the action of air pressure, multiple clamping rings 4 expand outward to clamp and fix the quartz tube.

[0081] Then slide the clamping rotating shaft 2 downward to make the bottom end of the clamping cylinder 3 be clamped and fixed to the top end of the dust removal rotating shaft 9. Then close the box body 1. At this time, the box bodies 1 are attracted and fixed to each other by magnetic attraction. Then drive the clamping rotating shaft 2, the clamping cylinder 3, the clamping ring 4 and the quartz tube to rotate through the first motor 5. During the rotation of the quartz tube, the grinding head on the grinding head fixing seat 8 grinds it. During the grinding process, the second motor drives the lead screw 7 to rotate, so that the grinding head fixing seat 8 moves back and forth along the axis direction of the lead screw 7.

[0082] The dust generated during the grinding process is sealed in the two box bodies 1, effectively preventing dust from polluting the environment and harming personnel. At the same time, during the rotation of the clamping cylinder 3, it drives the dust removal rotating shaft 9 and the centrifugal impeller 10 to rotate. During the rotation of the centrifugal impeller 10, the gas in the box body 1 is pumped into the inner wall of the wetting adsorption layer 12 by centrifugal force.

[0083] The moisture in the cyclone separation box 11 is absorbed by the wetting adsorption layer 12, making the wetting adsorption layer 12 in a wet state. The dust is thrown out under the high-speed rotation of the centrifugal impeller 10 and impacts the inner wall of the wetting adsorption layer 12. Under the dual action of centrifugal force and the moisture in the wetting adsorption layer 12, it is adsorbed by the wetting adsorption layer 12. The remaining unadsorbed dust moves downward in a swirling motion in the wetting adsorption layer 12 and is gradually adsorbed by the wetting adsorption layer 12.

[0084] The dust adsorbed by the wetting adsorption layer 12 is scraped off during the rotation of the first scraper 16 and the second scraper 17. And because the second scraper 17 is a spiral structure, it can push the scraped dust downward during the rotation, making it concentrated in the dust collection box 18. The gas after dust separation is discharged through the exhaust pipe 19. The planetary gear train 14 reduces the high-speed rotation of the dust removal rotating shaft 9 to a relatively low-speed rotation.

[0085] Efficient fixation: Through the design of the air supply system and the clamping ring 4, the quartz tube can be firmly fixed during the operation, ensuring the stability and uniformity of the grinding process.

[0086] Dust sealing and collection: The sealing design of the box body 1 and the combined use of the dust removal rotating shaft 9 and the centrifugal impeller 10 make the dust generated during the grinding process not leak out, effectively protecting the health of the operator and the working environment.

[0087] Dust treatment of the wet adsorption layer: The wet adsorption layer 12 always remains in a wet state, which can efficiently adsorb fine dust particles, prevent the dust from resuspending in the cyclone separation box 11, and improve the efficiency of dust treatment.

[0088] Dust scraping and centralized discharge: The designs of the first scraper 16 and the second scraper 17 enable the dust on the wet adsorption layer 12 to be effectively scraped and centrally collected, reduce the dust accumulation inside the equipment, and extend the service life of the equipment.

[0089] Convenient operation: The combination of the freely openable design of the box body 1 and the one-way intake valve enables the operator to conveniently load, maintain, and inspect the equipment, while ensuring the safety and airtightness of the equipment.

[0090] Combined with the current actual requirements, the above implementation methods adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
