The supports 11 are fixed at both ends and on both sides of the bottom of the mounting plate 1 and are used to support and stabilize the entire equipment to ensure that it does not shake or tilt during operation.

[0021] The base 26 is fixedly installed at the center of the upper surface of the mounting plate 1, and a groove is provided at the center of the surface of the base 26. It should be added that the base 26 is fixedly installed at the center of the mounting plate 1 and serves as the main structure of the dust removal device 2.

[0022] A dust suction hood 22 is fixedly installed at the center of one side of the groove. A second fixing plate 251 is fixedly installed at the center of the bottom inside the dust suction hood 22. A rotating shaft 252 is rotatably installed at the center of the top of the second fixing plate 251. A placement table 25 is fixedly installed at the top end of the rotating shaft 252. A trimming pen 23 is installed at the center of one side of the dust suction hood 22. The bottom of the trimming pen 23 is rotatably installed with a first fixing plate 24. It should be added that the length of the dust suction hood 22 is equal to the length of the groove. A number of spraying holes 221 are respectively and circularly penetrated through both ends of the outer wall of the dust suction hood 22. The number of spraying holes 221 corresponds to a number of nozzles 34, and the aperture size of the spraying holes 221 is larger than the aperture size of the nozzles 34. A cavity is provided inside the second fixing plate 251, and a first motor is fixedly installed inside the cavity. The bottom end of the rotating shaft 252 penetrates through the second fixing plate 251 and is coaxially connected to the output shaft of the first motor. A groove 253 is provided on the upper surface of the placement table 25. One end of the first fixing plate 24 is fixedly installed at the center of one side of the dust suction hood 22.

[0023] The spraying holes 221 are provided so that water sprays the dust inside the dust suction hood 22 from the nozzles 34 through the spraying holes 221. The trimming pen 23 grinds or trims the coating of the quartz crucible placed on the placement table 25 to remove uneven parts or burrs. The groove 253 is used to fix the quartz crucible to prevent the quartz crucible from moving or slipping during grinding or trimming. The dust suction hood 22 is used to collect the dust blown by the pneumatic cleaning gun rod 21 to ensure the cleanliness of the working area.

[0024] It should be noted that a pneumatic clamp is provided inside the groove 253, and the pneumatic clamp can be used to fix the quartz crucible to ensure stability during the grinding and trimming process.

[0025] A through hole communicating with the groove is penetrated through the center of the top of the base 26, and an opening is penetrated through the center of the top of the dust suction hood 22. One end of the pneumatic cleaning gun rod 21 is fixedly installed in the through hole and the opening.

[0026] It should be added that: An air amplifier is provided inside the pneumatic cleaning gun rod 21, which can use only a small amount of compressed air as the power source to drive the surrounding air to flow and form a high-pressure and high-speed air flow, converting the compressed air into an air flow with a strong suction force, thereby completing the adsorption of dust. A dust storage bag can be arranged at the end of the pneumatic cleaning gun rod 21 in the horizontal direction for centralized collection of dust.

[0027] The atomization device 3 includes a mounting pipe 33, which is fixedly installed inside both ends of the base 26. Support pipes 35 are fixedly connected between the two sides of the two mounting pipes 33 respectively.

It should be added that: An atomizer 32 is fixedly installed near the bottom of the water pipe 31, and the top end of the water pipe 31 is connected to a small shoulder-mounted water tank. The atomization of water by compressed air further reduces the harm of dust. At the same time, the heat generated during the cutting of the crucible can be reduced.

[0028] The spray nozzles 34 are fixedly connected in a surrounding manner on the inner peripheral wall of the mounting pipe 33 for spraying water mist to inhibit the generation or dispersion of dust. The support pipe 35 connects the two mounting pipes 33 to enhance the structural stability of the entire atomization device 3. The water pipe 31 is fixedly installed on the other side of the base 26, and the bottom penetrates through the base 26 and is connected to one of the mounting pipes 33 for supplying water source to the mounting pipe 33.

[0029] For the specific use of the present utility model, first, when the crucible repair worker trims the quartz crucible, place the quartz crucible to be polished or trimmed in the groove 253 of the placement table 25, turn on the first motor to make the placement table 25 start to rotate, thereby driving the quartz crucible to be polished or trimmed at multiple angles. Turn on the second motor to make the trimming pen 23 start to work to polish or trim the coating of the quartz crucible. Open the pneumatic cleaning gun rod 21, and the air amplifier inside it starts to generate a strong suction force to adsorb dust through the openings of the dust suction hood 22 and the through holes of the base 26. At the same time, the pneumatic cleaning gun rod 21 adsorbs the dust trimmed from the crucible to a designated area. During the polishing process, turn on the atomizer 32, water enters the mounting pipe 33 from the water pipe 31, and then the water sprays the dust inside the dust suction hood 22 through the spray holes 221 of the spray nozzles 34. After the crucible trimming is completed, turn off all motors and the pneumatic cleaning gun rod 21, and disconnect the connection of the water pipe 31.
