[0047] Example 2

[0048] refer to Figure 1-Figure 9, based on the improvement of Example 1: In order to automatically clean the dust, a plurality of scrapers 31 are protruding from the upper end surface of the lower sealing cover 3, and during the rotation process, the scrapers 31 can scrape the dust between the upper sealing gland 2 and the lower sealing cover 3. The plurality of scrapers 31 are arranged in a spiral shape on the upper end surface of the lower sealing cover 3, and a blade surface 311 is provided on the scraper 31. The angle α corresponding to the projection of the blade surfaces 311 of the plurality of scrapers 31 on the rotating shaft 1 covers at least 360° in combination, ensuring that the dust can be completely scraped off.

The second stepped portion 32 includes a transverse inclined surface 321 and a vertical surface 323, the angle between the transverse inclined surface 321 and the vertical surface 323 is an acute angle, and the transverse inclined surface 321 protrudes from the vertical surface 323 in the direction close to the rotating shaft 1, so that an outer protrusion 322 is formed between the transverse inclined surface 321 and the vertical surface 323. This design can further enhance the sealing effect and prevent dust from entering.

[0050] In the present application, first, the sealing adjustment block 4 and the stirring blade 9 are sleeved on the rotating shaft 1, and the stirring blade 9 is fixed on the rotating shaft 1 by screwing the bolt head 10;

[0051] Then, the two lower sealing covers 3 are placed in the positioning sleeve 13, and the two upper sealing glands 2 are placed in the two lower sealing covers 3. At this time, the two lower sealing covers 3 can approach each other through the conical surface, and the upper sealing glands 2 can be limited.

[0052] Then tighten the first bolts 22 to fix the two lower sealing covers 3 in the positioning sleeves 13, and the two upper sealing glands 2 in the lower sealing covers 3;

[0053] Then push the positioning sleeve 13 upward until the injection pipe 14 is inserted into the corresponding insertion hole 24, and the top of the upper sealing gland 2 is in contact with the bearing shell 11, and finally the two chucks 12 are clamped on the positioning ring 19. The positioning sleeve 13 can be in contact during the clamping process, and finally the two pairs of chucks 12 are fixed by the second bolt 25;

[0054] At this time, the rotation of the rotating shaft 1 can drive the stirring blade 9 to rotate to stir and mix the powder. The stirring blade 9 can drive the chuck 12 and the positioning sleeve 13 to rotate during the rotation. The rotation of the positioning sleeve 13 can drive the two lower sealing covers 3 to rotate. During the rotation of the lower sealing cover 3, the dust between the upper sealing cover 2 and the lower sealing cover 3 can be cleaned out by the scraper 31. The rotating shaft 1 can drive the protrusion 18 to rotate during the rotation. When the protrusion 18 contacts the piston rod 16, it can drive the piston rod 16 to move into the injection pipe 14, which can The gas is compressed. Since both the intake pipe 15 and the nozzle 27 are provided with a one-way valve, the piston rod 16 can push the gas in the nozzle 14 to be discharged through the nozzle 27 during the movement of the piston rod 16 into the nozzle 14. During the gas discharge process, the dust between the upper sealing cover 2 and the lower sealing cover 3 can be further cleaned. When the bump 18 is away from the piston rod 16, the piston rod 16 can be reset and moved under the action of the spring 17. During the outward movement of the piston rod 16, the external gas can enter the nozzle 14 through the intake pipe 15, and reciprocating cleaning is performed in sequence.
