[0031] Example 2

[0032] A raw material mixing device with a heating function, based on example 1, the following improvements are made, as shown in Figure 4 The transmission assembly 11 includes a box body 20 and a driving motor 19, the box body 20 is fixed to the top end outer wall of the tank body 1, the driving motor 19 is installed on the top end outer wall of the box body 20, the inner wall of the box body 20 is rotatably connected with an oval gear one 17 and an oval gear two 18, the oval gear one 17 is in transmission engagement with the oval gear two 18, the rotating shaft of the oval gear one 17 is connected with the connecting pipe 12, and the rotating shaft of the oval gear two 18 is connected with the output shaft of the driving motor 19.

[0033] When the drive center shaft 6 rotates, the drive motor 19 drives the oval gear 2 18 to rotate, and the oval gear 2 18 drives the oval gear 17 to rotate, driving the center shaft 6 to rotate. During the transmission process, the oval gear 2 18 and the oval gear 17 make pure rolling motion in an oval curve. When the oval gear 2 18 rotates once, the transmission ratio changes periodically twice to avoid stirring at a certain speed for a long time, which would cause the clay and lubricating oil to rotate at the same speed as the center shaft 6, reducing the stirring effect.

[0034] By setting oval gear 17 and oval gear 2 18, the rotation speed of the central shaft 6 is changed periodically, avoiding stirring at a certain speed for a long time, which would cause the clay and lubricating oil to rotate at the same speed as the central shaft 6, thus reducing the stirring effect.

[0035] Working principle: During mixing, the bleached clay, after being pretreated, crushed, and dried by the pretreatment mechanism 2, enters the tank 1 through the connecting flange 3. Lubricating oil is injected into the tank 1 through the feed inlet 5. The drive motor 19 drives the oval gear 18 to rotate, which in turn drives the oval gear 17 to rotate, thus rotating the central shaft 6. During the transmission process, the oval gear 18 and oval gear 17 perform pure rolling motion in an oval curve. With each rotation of the oval gear 18, the transmission ratio changes periodically twice, driving the spiral stirring blade 7 and the stirring rod 8 to rotate and stir. The spiral stirring blade 7 can carry the bleached clay and lubricating oil in the tank 1 upwards, allowing them to move longitudinally and achieving multi-level mixing, thus improving the mixing effect. The scraper 9 scrapes the bleached clay and lubricating oil located at the bottom of the tank 1 upwards and conveys them upwards through the spiral stirring blade 7, preventing them from being submerged. The clay and lubricating oil at the bottom of the tank 1 are difficult to mix thoroughly. After mixing, the mixture is discharged from the discharge pipe. At the same time, the transmission component 11 drives the central shaft 6 to reverse. The spiral stirring blade 7 can promote the discharge of the mixture from the discharge pipe and prevent the mixture from clogging the discharge pipe. After processing, the pretreatment mechanism 2 is removed from the connecting flange 3. Then the tank cover 4 is removed from the top of the tank 1. The combination of the central shaft 6 and the tank cover 4 is moved out with the tank cover 4. Then the sliding sleeve 13 is turned. The sliding sleeve 13 drives the threaded cylinder 14 to rotate, causing the threaded cylinder 14 to disengage from the connecting pipe 12. The sliding block 16 moves along the central shaft 6 with the sliding sleeve 13. After the threaded cylinder 14 is disengaged from the connecting pipe 12, the insertion rod 15 can be disengaged from the connecting pipe 12. The central shaft 6 is removed, and the combination of the central shaft 6, spiral stirring blade 7, stirring rod 8 and scraper 9 is cleaned.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
