It is understood that the heating hole 41 is connected with a heat supply device (not shown) through a pipeline, and the heat supply device is used for flowing a heat-conducting medium, such as hot air, hot water, etc., through the stirring shaft 4 and the stirring column 5, so that heat is transferred to the material in the stirring cylinder 2 through the stirring shaft 4 and the stirring column 5 for heating and drying.

In this embodiment, when the device is installed, the handle 625 rotates the threaded rod 623 to rotate, so that the threaded rod 623 is connected with the supporting block 614 through the thread, and the movable clamp plate 622 is driven to be far away from the fixed clamp plate 621. In the process, the sliding rod 624 is supported by the supporting block 614, so that the movable clamping plate 622 can be prevented from rotating around the threaded rod 623, and the subsequent clamping of the stirring column 5 by matching with the fixed clamping plate 621 can be ensured.

After the movable clamp plate 622 and the fixed clamp plate 621 are separated from each other, a user can sleeve the sleeve hole 612 to one end of the stirring column 5 far away from the stirring shaft 4, in the process, the fixture block 626 needs to be aligned with the clamping groove 52, so that the stirring column 5 passes through the sleeve hole 612, when the stirring column is inserted between the movable clamp plate 622 and the fixed clamp plate 621, the fixture block 626 is clamped into the clamping groove 52, and meanwhile, the protruding part of the scraper 613 needs to face the rotation direction of the stirring shaft 4, so that the effect that the protruding position of the fixed scraper 613 faces is achieved.

Then the threaded rod 623 is rotated reversely and screwed, so that the threaded rod 623 drives the movable clamping plate 622 to be close to the fixed clamping plate 621, the movable clamping plate 622 and the fixed clamping plate 621 clamp the stirring column 5, and the effect of fixing the blade assembly 6 is achieved. The blade assembly 6 can be mounted by repeating the above steps.

After the stirring shaft 4 is installed in the stirring cylinder 2, the user can rotate the threaded rod 623 through the handle 625 at any time from the opening side of the scraper 613 to loosen the movable clamp plate 622 so as to adjust the position of the scraper 613, and after the adjustment is completed, the threaded rod 623 is screwed down to fix the scraper 613. So that the scraper 613 can be adjusted to be attached to the inner wall of the mixing drum 2 by the user when there is a gap between the scraper 613 and the inner wall of the mixing drum 2. In the adjusting process, the clamping block 626 is clamped with the clamping groove 52, so that the scraper 613 can be prevented from deviating in the direction in the position adjusting process, and the effects of conveniently adjusting the position of the scraper 613 and preventing the scraper 613 from deviating in the angle are achieved.

When drying, the user can add the material into the mixing drum 2 through the opening 21, the driver 32 drives the mixing shaft 4 to rotate through the driving gear 33, the chain 34 and the driven gear 31, and the mixing shaft 4 drives the mixing column 5 to rotate to mix the material. Meanwhile, the heat supply device enables the heat-conducting medium to flow through the stirring shaft 4 and the stirring column 5, so that heat is transferred to the material in the stirring cylinder 2 through the stirring shaft 4 and the stirring column 5 to be heated and dried, and the opening 21 is used for discharging water.

The rotatory in-process of (mixing) shaft 4 can drive the inner wall that the scraper blade 613 constantly scraped churn 2, will adsorb under the material of churn 2 inner wall is hung, reaches the effect of clean churn 2 inner wall to avoid the wet material to pile up at churn 2 inner wall, lead to drying efficiency to reduce, or dry not enough problem.

The paddle board 611 is used for supporting the stirring column 5, and the stirring column 5 is prevented from being bent and damaged due to insufficient strength.

Because scraper blade 613 is the slope form for 2 inner walls of churn, there is certain angle between scraper blade 613 and the 2 inner walls of churn promptly, can help scraper blade 613 to downcut the absorbent material of 2 inner walls of churn on the one hand, the scraping effect has been strengthened, another convenience, the material of 2 inner walls of churn department is pushed to the churn 2 in the middle of through the inclined plane that scraper blade 613 formed, make the material at edge be close to the higher 2 central points of churn of temperature and put every increase heating effect to the material at edge, with the speed that promotes drying.

Because the middle of the scraper 613 protrudes towards one side of the rotation direction of the stirring shaft 4, the resistance of the scraper 613 to push away materials can be reduced, and the problem that the stirring column 5 is bent and damaged due to excessive resistance is avoided.
