[0006] In the above technical solution, the material is poured into the kettle body through the feed port, the lid is closed, and the rotary motor is started. The rotary motor drives the stirring paddle to rotate and stir the material. During the rotation of the output end of the rotary motor, the fan blade can rotate to cool the fixed end of the rotary motor.

[0007] Furthermore, a support frame is installed at the top of the vessel body, the fixed end of the rotary motor is installed on the support frame, and the driving component includes a driving bevel gear coaxially fixedly installed on the output end of the rotary motor and a follower bevel gear fixedly installed with the fan blade, wherein the driving bevel gear and the follower bevel gear mesh.

[0008] In the above technical solution, the rotation of the output end of the rotary motor can drive the bevel gear to rotate, and the rotation of the bevel gear can drive the follower bevel gear and the fan blade to rotate. The fan blade can deliver air to the fixed end of the rotary motor to cool the rotary motor.

[0009] Furthermore, the fan blades include a fixed block fixedly mounted on the follower bevel gear and several fan blades formed on the fixed block. A receiving basket is installed on the fan blades, dry ice is provided in the receiving basket, and a sealing plate is installed on the receiving basket. The sealing plate is fixed to the receiving basket by a fastener.

[0010] In the above technical solution, dry ice can generate cold air, and the fan blades can deliver the cold air to the surface of the rotating motor during rotation, resulting in a better cooling effect on the rotating motor.

[0011] Furthermore, several follower bevel gears and fan blades are provided, and the several follower bevel gears and several fan blades are arranged around the axis of the output end of the rotary motor.

[0012] In the above technical solution, by setting several follower bevel gears and fan blades, the fan can dissipate heat evenly to the rotating motor.

[0013] Furthermore, the fastener is a screw.

[0014] In the above technical solution, the sealing plate is fixed to the container with screws to prevent the dry ice from leaving the container.

[0015] Furthermore, the stirring paddle includes a stirring rod, an arc plate formed at the end of the stirring rod, and two connecting plates. The two connecting plates are formed at both ends of the arc plate along its length, and the connecting plates are provided with connecting holes.

[0016] In the above technical solution, when installing the agitator, firstly, the arc plates of the two agitators are arranged opposite each other and the arc plates are attached to the side wall along the length of the agitator shaft. Then, the bolts are inserted into the two connecting holes of the two oppositely arranged connecting plates, and the nuts are connected to the bolts. The two agitators can then be fixed relative to the agitator shaft due to friction.

[0017] Furthermore, the upper end of the fastener is formed with anti-slip texture.

[0018] In the above technical solution, the anti-slip texture makes it easier for a person to turn the screws and open the sealing plate.

[0019] Furthermore, several lifting lugs are formed on the outer wall of the vessel.

[0020] In the above technical solution, the overall weight of the vessel is relatively heavy. By setting up lifting lugs, it is easier for workers to move the vessel.

[0021] In summary, this application has the following technical effects: the material is poured into the kettle body through the feed port, the lid is closed, the rotary motor is started, the rotary motor drives the stirring paddle to rotate and stir the material, and the output end of the rotary motor can drive the fan blade to rotate and cool the fixed end of the rotary motor.

There are eight stirring paddles 4 in total. Each stirring paddle 4 includes a stirring rod 41, an arc plate 42 formed at the end of the stirring rod 41, and two connecting plates 43. The two connecting plates 43 are formed one-to-one at both ends of the arc plate 42 along its length. The connecting plates 43 have connecting holes. During installation, the arc plates 42 of the two stirring paddles 4 are first arranged opposite each other and the arc plates 42 are made to fit against the side wall along the length of the stirring shaft 3. Then, bolts are inserted into the two connecting holes on the two opposite connecting plates 43, and nuts are connected to bolts. The two stirring paddles 4 can then be fixed in position relative to the stirring shaft 3 due to friction.

[0028] Referring to Figures 1 and 3, this embodiment also includes three fan blades 6. Each fan blade 6 includes a fixing block 61 and three fan blades 62 formed on the fixing block 61. Each of the three fan blades 62 is equipped with a receiving basket 11. The receiving basket 11 is used to hold dry ice. A sealing plate 12 is installed at the opening of the receiving basket 11 by means of a fixing member. The sealing plate 12 can limit the dry ice to prevent the dry ice from falling out of the receiving basket 11.
