Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The rotation of the driven gear 1 4 causes the stirring plate 13 to stir and mix the polyethylene wax raw material inside the inner shell 21, and at the same time, the scraper 9 is used to scrape and clean the inner wall of the inner shell 21 to prevent the polyethylene wax from accumulating on the inner wall of the inner shell 21 and being difficult to clean, thereby affecting the subsequent mixing and stirring effect. Furthermore, several evenly distributed gears on the outer side of the rotating shaft 7 are welded and fixed to the driving gear 2 8, and the outer side of the rotating drum 3 is welded and fixed to the sleeve 11. The rotating drum 3 is rotatably connected to the outer side of the connecting shaft 10 through the sleeve 11. One end of the connecting shaft 10 extends to the inside of the oil storage chamber 15 and is welded and fixed to the driven gear 2 12. The driven gear 2 12 is meshed and connected with the driving gear 2 8. The rotating drum 3 and the rotating shaft 7 rotate synchronously, and the rotating shaft 7 drives the driving gear 28 to make the connecting shaft 10 and the driven gear 2 12 rotate, thereby driving the stirring plate 13 to rotate around the rotating drum 3 as the center and rotate at the same time, so as to fully mix the upper and lower layers of polyethylene wax, and avoid the situation that the circumferential rotation of the stirring plate 13 easily leads to the uniform distribution of the upper and lower layers of polyethylene wax. At the same time, the outer side of the connecting shaft 10 is welded and fixed to a plurality of stirring plates 13, and the connecting shaft 10 is evenly distributed on the outer side of the rotating drum 3. The stirring plates 13 are cross-distributed in the horizontal direction and the vertical direction in sequence, so as to expand the stirring contact area of the stirring plates 13, and the gaps generated by the cross-distributed stirring plates 13 enhance the shear force on the polyethylene wax during the stirring process, thereby avoiding agglomeration and bubble pushing in the polyethylene wax raw material, and enhancing the stirring and mixing efficiency of the polyethylene wax.

The oil holes 14 are all located inside the rotating shaft 7 and are connected to the oil storage chamber 15. The oil storage chamber 15 is set between the rotating shaft 7 and the drum 3. The top of the rotating shaft 7 is rotatably connected to one end of the oil inlet pipe 18, and the bottom of the rotating shaft 7 is rotatably connected to one end of the oil delivery pipe 16. The oil delivery pipe 16 is spirally fixedly distributed on the outside of the inner shell 21. The inner shell 21 is sleeved inside the outer shell 1. The ultrasonic generator 20 inside the inner shell 21 is connected and fixed. A one-way valve is set on the outside of the inner shell 21. The upper surface of the outer shell 1 is connected and fixed to the oil pump 17 by bolts. One end of the oil delivery pipe 16 is welded and fixed to the output end of the oil pump 17. The output end of the oil pump 17 is connected to the rotating shaft 7 through the oil inlet pipe 18. A heater 19 is set on the outside of the oil inlet pipe 18. The outside of the outer shell 1 is fixedly connected to the controller 27. The controller 27 is electrically connected to the driving gear 6 and the oil pump 17 through a wire. The outside of the outer shell 1 is fixedly connected to the support column 28. The oil is pumped into the shaft 7 through the oil inlet pipe 18. In the process, the oil is heated by the heater 19. After entering the shaft 7, the oil is discharged from the top oil hole 14 into the oil storage chamber 15, and then discharged from the bottom oil storage chamber 15 and enter the oil delivery pipe 16 to flow back to the oil pump 17 to form a circulation loop. The outer side of the inner shell 21 is heated by the spirally distributed oil delivery pipe 16, and the hot oil in the oil storage chamber 15 exchanges heat with the drum 3, that is, the contact area with the polyethylene wax in the inner shell 21 is expanded through the drum 3 and the stirring plate 13. At the same time, the fixed position of the heating source causes the polyethylene wax raw material to be locally heated to coking or even unevenly distributed. The oil delivery pipe 16 is located between the outer shell 1 and the inner shell 21, and an insulation layer and heat insulation cotton are arranged between the outer shell 1 and the inner shell 21, which effectively reduces the heat loss of the hot oil in the oil delivery pipe 16 and the waste of resources, while enhancing the uniform heating effect of the polyethylene wax. In another embodiment, the upper surface of the top plate 2 is welded and fixed to the filter box 22, the interior of the filter box 22 is connected to the filter box 22 through the air hole 25, the interior of the filter box 22 is slidably connected to the outer side of the pressing plate 23, the pressing plate 23 is welded and fixed to one end of the spring 24, the purification plate 26 is located at the top of the filter box 22, the spring 24 is located between the pressing plate 23 and the purification plate 26, a plurality of air holes 25 are provided on the upper surface of the top plate 2, the purification plate 26 is provided inside the filter box 22, the filter plate and the adsorption plate are provided inside the purification plate 26, so as to absorb and process the harmful tail gas generated in the production process of polyethylene wax, there is a gap for gas flow between the outer side of the pressing plate 23 and the filter box 22, the air hole 25 is located at the bottom of the pressing plate 23, The ultrasonic generator 20 generates high and low currents, so that the raw materials inside the inner shell 21 are vibrated and degassed, which is convenient for the discharge of harmful gases in the polyethylene wax and solvent, and avoids the presence of bubbles in the raw materials that affect the subsequent processing effect. The polyethylene wax raw material will produce water vapor during the heating process. The production of tail gas and water vapor will increase the pressure inside the inner shell 21, thereby pushing the pressing plate 23 to move upward, squeezing the spring 24 while allowing the gas to enter the filter box 22 from the air hole 25, and then be discharged into the air after being filtered and purified by the purification plate 26, thereby reducing damage to the staff. A one-way valve is also arranged on the outside of the inner shell 21. The elastic force of the spring 24 pushes the pressing plate 23 to close the air hole 25, so that a sealed space is formed inside the inner shell 21, thereby avoiding interference from external air and dust. The air intake of the one-way valve facilitates the discharge of the raw materials inside the outer shell 1 from the discharge port at the bottom, and the scraping of the scraper 9 is used to avoid the problem that the raw materials adhere to the inner wall of the inner shell 21 and are difficult to clean. Working principle: When in use, the staff puts raw materials such as polyethylene wax into the feeding port on the top of the top plate 2, and the driving gear 1 6 drives the driven gear 1 4 and the driving gear 2 8 to rotate synchronously through the motor 5, so that the driven gear 1 4 and the rotating shaft 7 rotate in the opposite direction, and the stirring plate 13 stirs and mixes the polyethylene wax raw materials inside the inner shell 21 through the rotation of the driven gear 1 4, and further the rotating shaft 7 drives the driving gear 2 8 to make the driven gear 2 12 rotate synchronously, so that the connecting shaft 10 and the stirring plate 13 rotate, and through the cooperation of several connecting shafts 10 and stirring plates 13, the stirring plate 13 rotates while rotating, so as to fully mix the upper and lower layers of polyethylene wax, and avoid the situation that the circumferential rotation of the stirring plate 13 easily leads to uniform distribution of the upper and lower layers of polyethylene wax; The oil is pumped into the shaft 7 through the oil inlet pipe 18. In the process, the oil is heated by the heater 19. After entering the shaft 7, the oil is discharged from the top oil hole 14 into the oil storage chamber 15, and then discharged from the bottom oil storage chamber 15 and enters the oil delivery pipe 16 to flow back to the oil pump 17 to form a circulation loop. The outer side of the inner shell 21 is heated by the spirally distributed oil delivery pipe 16. The hot oil in the oil storage chamber 15 exchanges heat with the drum 3 to heat the polyethylene wax in the inner shell 21. The drum 3 and the stirring plate 13 are combined to stir and mix, so that the heating of the polyethylene wax is more uniform, and the consistency of the distribution of the polyethylene wax is improved. The raw materials inside the inner shell 21 are vibrated and degassed by the ultrasonic generator 20, which facilitates the discharge of harmful gases in the polyethylene wax and the solvent and reduces the bubbles inside the raw materials. The rotation of the raw materials by the stirring plate 13 and the heating of the raw materials by the oil body further increase the discharge of bubbles and water vapor. The exhaust gas and water vapor generated will push the pressing plate 23 to move upward, squeeze the spring 24, and allow the gas to enter the filter box 22 from the air hole 25, and then be discharged into the air after being filtered by the purification plate 26.
