[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-3As shown, an anti-clogging powder feeder includes a powder feeding air path connection device 1. A feeding driver 2 is provided at the front middle of the powder feeding air path connection device 1. A powder hopper 3 is provided at the upper middle of the powder feeding air path connection device 1. An internal circulation drying powder pre-storage hopper 4 is provided on the upper outer surface of the powder hopper 3. Large particle powder filter assembly 5 is provided on the inner surface of the internal circulation drying powder pre-storage hopper 4. The internal circulation drying powder pre-storage hopper 4 includes a feeding hopper 401, a sealing cover 402, a sealing connection groove 403, a dust filter screen 404, a heating fan 405, a side air supply plate 406, a one-way exhaust valve 407, and a return air duct 408. The large particle powder filter assembly 5 includes a filter support plate 501, an internal support frame 502, a mesh dust filter column 503, an arc-shaped guide cover 504, a one-way guide pipe 505, a feeding driver 506, and a connecting base 507.

[0025] It should be noted that this utility model is an anti-clogging powder feeder. In use, powder is first added to the internal circulation drying powder pre-storage silo 4, which dries the powder. After drying, the powder is filtered by the large particle powder filter assembly 5 and guided to the powder silo 3. Then, the feeding driver 2 drives the powder feeding air connection device 1 to transport the powder inside the powder silo 3. The internal circulation drying powder pre-storage silo 4 includes a feeding bin 401, a sealing cover 402, a sealing connection groove 403, a dust filter 404, and a heating fan 405. 5. The side air supply plate 406, one-way exhaust valve 407, and return air duct 408 are used to first add powder to the feeding hopper 401. After the powder is added, the heating fan 405 guides the air inside the feeding hopper 401 to the heating fan 405 through the return air duct 408 and the dust filter 404. The heating fan 405 heats and dries the incoming air. The dried and heated air is blown out through the one-way exhaust valve 407 on the side air supply plate 406. The heated and dried air blown out by the one-way exhaust valve 407 purifies the powder inside the feeding hopper 401. The airflow blows out the moisture in the powder, completing the drying process. The moisture in the powder is then guided through the return air duct 408 and the dust filter 404 to the heated fan 405 for further heating and drying, thus completing the circulating drying process. During use, this allows for the continuous drying of added powder, reducing moisture content and preventing clogging due to excessive humidity. The large-particle powder filter assembly 5 includes a filter support plate 501, an internal support frame 502, a mesh dust filter column 503, an arc-shaped guide cover 504, a one-way guide pipe 505, and a feeding driver 5. 06 and connecting base 507, in use, the arc-shaped guide cover 504 on the internal support frame 502 first diverts the added powder, distributing the powder to the periphery of the mesh dust filter column 503. After dispersion, the feeding driver 506 generates guiding force inside the mesh dust filter column 503 through the one-way guide pipe 505, guiding the dust outside the mesh dust filter column 503 through the mesh dust filter column 503 and guiding it to the powder hopper 3 to complete the post-filtering feeding work. In use, it can complete the filtering of impurities and larger particles in the powder, avoiding the blockage of the powder feeder by larger particles.
