The rotation of the impeller generates a suction force, which draws the dust-laden gas in the fixed frame into the purification chamber through the suction port. The fiber filter plate in the purification chamber intercepts impurities and particulate matter in the gas. Finally, the clean gas is discharged from the air outlet. It has a dust removal and purification function, timely collects and treats the generated dust and impurities, protects the health of personnel, and improves the surrounding environment.

A threaded plate 6 is threadedly connected to the surface of the reciprocating screw 4. A positioning mechanism 10 is provided on the other side of the fixed frame 19. By sequentially inserting steam seals of the same batch into the rotating cylinder 8, when the steam seals are processed... After the sealing is completed, the second cylinder 101 is activated to push the first baffle 102 to move and position it. Then, the second motor 7 and the third motor 92 are activated simultaneously. After the second motor 7 is activated, it will drive the rotating cylinder 8 and the workpiece to rotate. After the third motor 92 is activated, it will drive the grinding wheel 93 to rotate. After the first cylinder 2 is activated, it will drive the housing 3 and the grinding wheel 93 to move downward. When the grinding wheel 93 is in contact with the workpiece, the first motor 5 is activated to drive the threaded plate 6 to rotate. When the threaded plate 6 rotates, it will drive the threaded plate 6 and the grinding wheel 93 to move slowly to the right. This can achieve a good grinding effect and can process multiple workpieces of the same batch at the same time, thus improving processing efficiency.
[0028] Referring to Figures 1 and 3, the grinding mechanism 9 includes a fixed plate 91, which is bolted to the bottom of the threaded plate 6. A third motor 92 is bolted to one side of the fixed plate 91, and a grinding wheel 93 is fixedly sleeved at the output end of the third motor 92. Through the arrangement of the fixed plate 91, the third motor 92 and the grinding wheel 93, foreign objects, stains and burrs and other impurities on the surface of the gas seal workpiece can be removed to achieve the purpose of cleaning and smoothing.
[0029] Referring to Figures 1 and 2, the positioning mechanism 10 includes a second cylinder 101, which is bolted to the other side of the fixed frame 19. A first baffle 102 is installed on the piston end of the second cylinder 101, and a second baffle 103 is rotatably connected to the other side of the first baffle 102. Both the first baffle 102 and the second baffle 103 have through grooves inside. By setting the second cylinder 101, the first baffle 102 and the second baffle 103, the steam seal workpiece that slides onto the surface of the rotating cylinder 8 can be fixed. After the second cylinder 101 is started, it drives the first baffle 102 and the second baffle 103 to move to the left. When the second baffle 103 moves to the left, it pushes the workpiece to be positioned.
[0030] Referring to Figure 2, a slide rail 15 is bolted inside the housing 3, and a slider 16 that is slidably connected to the slide rail 15 is welded to the top of the threaded plate 6. By setting the slide rail 15 and the slider 16, the threaded plate 6 can be limited to prevent it from flipping over during left and right movement.
[0031] Referring to Figure 2, the reciprocating screw 4 and the threaded plate 6 are both made of stainless steel. The reciprocating screw 4 and the threaded plate 6 have the characteristics of high strength, low density and excellent corrosion resistance.
[0032] Brief description of the usage process: By sequentially inserting the steam seals of the same batch into the rotating cylinder 8, after the steam seals are inserted, the second cylinder 101 is started to push the first baffle 102 to move and position it. Then, the second motor 7 and the third motor 92 are started at the same time. After the second motor 7 is started, it will drive the rotating cylinder 8 and the workpiece to rotate. After the third motor 92 is started, it will drive the grinding wheel 93 to rotate. After the first cylinder 2 is started, it will drive the housing 3 and the grinding wheel 93 to move downward. When the grinding wheel 93 is in contact with the workpiece, the first motor 5 is started to drive the threaded plate 6 to rotate. When the threaded plate 6 rotates, it will drive the threaded plate 6 and the grinding wheel 93 to move slowly to the right.
[0033] Example 2:
[0034] Referring to Figures 1 and 2, a grinding device for gas seal processing includes a purification box 11 bolted between the bottom of a fixed frame 19 and a frame 1. A suction fan 12 is bolted inside the purification box 11, and a fiber filter plate 13 is placed inside. An air intake 14 communicating with the purification box 11 is opened at the bottom of the fixed frame 19. When the suction fan 12 is started, its internal impeller rotates, generating suction. Under this suction, dust-laden gas inside the fixed frame 19 is drawn into the purification box 11 through the air intake 14. The fiber filter plate 13 in the purification box 11 intercepts impurities and particulate matter in the gas. Finally, clean gas is discharged from the air outlet. This device possesses dust removal and purification functions, promptly collecting and treating generated dust and impurities, protecting personnel health, and improving the surrounding environment.
[0035] Referring to Figure 2, the top and bottom of the fiber filter plate 13 are both secured with a retainer 17, and the other side of the retainer 17 is bolted to the inside of the purification box 11. The retainer 17 can limit the fiber filter plate 13 and prevent it from tipping over after being placed in the box.
[0036] Referring to Figure 2, an air outlet is provided on the other side of the purification box 11, and a dustproof net 18 is attached to the other side of the purification box 11. The diameter of the dustproof net 18 is larger than the diameter of the air outlet. The dustproof net 18 can play a dustproof role and prevent dust in the air from falling into the suction fan 12.
[0037] Brief description of the usage process: By starting the suction fan 12, the internal impeller will rotate. When the impeller rotates, it will generate a suction force. Under the action of the suction force, the dust-laden gas in the fixed frame 19 will be sucked into the purification box 11 through the suction port 14. The fiber filter plate 13 in the purification box 11 will intercept impurities and particulate matter in the gas. Finally, the clean gas will be discharged from the air outlet.
