[0024] The stirring paddle includes a stirring shaft 304 , and the stirring shaft 304 is connected to a paddle 305 via a cross bar 303 . The paddle 305 is spirally arranged, closely attached to the inner wall of the tank body 20 and extending to the bottom of the tank body 20 .

[0025] The upper end of the stirring shaft 304 is located outside the tank body 20 and is connected to the stirring motor 301 through the reducer 302 .

[0026] like Figure 2 As shown, the crushing mechanism 10 includes a motor 101, a front end cover of the motor 101 is connected to a motor mounting seat 105, a filler shell 104 is installed at the front end of the mounting seat 105, a crushing through hole is opened at the bottom of the tank body 20, and a front end cover of the filler shell 104 is sealed and installed at the bottom of the crushing through hole. The output shaft of the motor 101 is located at the bottom of the tank body 20 and a blade group is installed.

[0027] The motor 101 is a variable frequency motor, and the filler housing 104 is filled with fillers.

[0028] The blade assembly includes a plurality of blades 103 , which are sleeved on the output shaft of the motor 101 along the axial direction. Adjacent blades 103 are staggered 90 degrees in the vertical direction and separated by retaining rings 106 , and the edges of the blades 103 are milled around the blades.

[0029] The side wall discharge structure 50 includes a discharge pipe 502, on which a feed pipe end, a discharge pipe end, and a cylinder pipe end are connected, and the vertically arranged discharge pipe end is located between the feed pipe end and the cylinder pipe end. A discharge port is opened at the lower part of the tank body 20, and the feed pipe end of the discharge pipe 502 is connected to the discharge port of the tank body 20 through a mounting sleeve 504, and a plug cylinder 503 is installed at the cylinder pipe end, and the piston end of the plug cylinder 503 faces the discharge port and is installed with a plug 501.

[0030] The mounting sleeve 504 and the discharge pipe 502 are sealed with an O-ring and connected with bolts.

[0031] The discharge pipe 502 is provided with an observation pipe end connected to the discharge pipe end; a sight glass 506 is installed on the observation pipe end, and the sight glass 506 is equipped with a scraper to facilitate clear observation of the discharge situation of the discharge pipe end of the discharge pipe 502 at any time.

[0032] In order to prevent the plug 501 from deviating from the discharge port, a guide column 505 is provided parallel to one side of the piston rod of the plug cylinder 503 . The guide column 505 slides in the flange of the plug cylinder 503 , and the end of the guide column 505 is threadedly connected to the plug 501 .

[0033] The working process of the utility model is as follows:

[0034] like Figure 1 As shown, the stirring motor 301 drives the stirring paddle to rotate through the reducer 302, and the rotating stirring paddle continuously turns the material in the tank body 20. The lower end of the outer blade 305 of the stirring paddle is close to the bottom of the tank body 20, and the bottom crushing structure 10 rotates at a high speed. Figure 2 As shown, the motor 101 drives the main shaft 102 to rotate at high speed, and the rotation of the main shaft 102 drives the five blades 103 arranged at 90 degrees at the end to rotate at high speed. The blades 103 crush the block materials at the bottom of the tank body 20 in layers along the axial direction, so that the materials participate in the circulation stirring again, and are fully mixed and dried. A packing shell 104 is added between the blades 103 and the motor mounting seat 105 and is cooled to prevent overheating from causing deformation of the main shaft 102 and the packing, ensuring sealing while extending the service life of the packing seal.

[0035] The container adopts a side wall discharge structure 50, such as Figure 1 A plug 501 is installed inside the discharge structure 50, and the end face of the plug 501 is flush with the inner wall of the tank body 20. An O-ring is used to seal the plug 501 and the mounting sleeve 504. The outer circle of the plug 501 and the inner hole of the mounting sleeve 504 are clearance-matched, and the clearance is 0-0.1mm. When the material is stirred, mixed and dried inside the tank body 20, material accumulation in the mounting sleeve 504 area is prevented; the lowest point of the mounting sleeve 504 is lower than the bottom of the inner cylinder of the tank body 20. When the stirring and mixing is completed and the material is discharged, the discharge plug 501 is moved outward by the plug cylinder 503. When it moves to a certain position, the material is discharged along the downward discharge hole on the left side of the discharge pipe 502.

[0036] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
