On the other hand, some powder materials require heating during mixing, which existing mixing equipment cannot meet, or suffers from poor heating effect or overheating that damages the molecular structure of the material, resulting in wasted time and costs. Therefore, there is an urgent need to develop a lithium battery powder mixing device that has a good mixing effect, can effectively prevent dust overflow, can meet the requirements for heating materials, and is low in cost.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figures 1-2 The embodiment of the lithium battery powder mixing device of this utility model shown includes a conical tank 1, a tank cover 2 covering the conical tank 1, a mixing motor 3 mounted on the tank cover 2, a rotating main shaft 4 coaxially connected to the output shaft of the mixing motor 3, inner blades 5 spirally wound from top to bottom on the rotating main shaft 4, and outer blades 6 mounted on the rotating main shaft 4. The two ends and the middle portion of the outer blades 6 are fixed to the rotating main shaft 4 by connecting rods 13. The inner blades 5 are arranged in a ribbon-like configuration; in this embodiment, the pitch of the inner blades 5 is 120 mm. Each material is fed into the conical tank 1 through the feed inlet. The mixing motor 3 operates, driving the rotating main shaft 4 to rotate, which in turn drives the inner blades 5 and the outer screw blades 6 to stir and mix the materials, thereby achieving good mixing of the materials. The mixing effect is good. By using the inner blades 5 and the outer screw blades 6 to stir the materials together, the materials in all parts of the conical tank 1 can be stirred, resulting in good mixing effect and effectively improving mixing efficiency.

[0024] The can lid 2 is also equipped with a dust removal assembly 7, which includes: a dust collection box 70 fixed on the can lid 2, an exhaust fan 71 installed at the top of the dust collection box 70, four filter bags 72 installed inside the dust collection box 70, and a blowing assembly 73 horizontally arranged inside the dust collection box 70 and above the filter bags 72. The blowing assembly 73 shakes the material adsorbed on the outer wall of the filter bags 72 into the conical can 1. The blowing assembly 73 includes: an air tank, a connecting pipe 731 connected to the air outlet of the air tank, and a nozzle 732 installed on and connected to the connecting pipe 731. The nozzle 732 is located directly above the filter bags 72. The exhaust fan 71 draws air outward, causing the raised dust to be adsorbed on the filter bags. Air is blown out through an air bag onto the outer wall of the filter bag 72. The air passes through a connecting pipe 731 and is blown out from the nozzle 732. The airflow causes the filter bag 72 to shake, shaking off the dust adhering to the outer wall of the filter bag 72 into the conical tank 1. This effectively prevents dust from overflowing and avoids harm to the health of the workers. Since the materials are fed into the conical tank 1 according to the specified ratio, the dust removal component 7 can effectively prevent dust from overflowing and causing errors in the ratio, thereby improving the ratio accuracy and product quality. In this embodiment, four filter bags 72 are provided in the dust collection box 70. The four filter bags 72 are arranged in a rectangular array. Four nozzles 732 are provided, and the four nozzles 732 are located directly above the four filter bags 72.

[0025] A jacket 8 is provided on the outer wall of the conical tank 1, forming a jacket 9 between the jacket 8 and the conical tank 1. At least one electric heating tube 10 is inserted into the jacket 9. The lower end of the jacket 8 has a water inlet 11, and the upper end has a water outlet 12. Both the water inlet 11 and the water outlet 12 are connected to the jacket 9. A medium is introduced into the jacket 9 through the water inlet 11, and the medium in the jacket 9 is heated by the multiple electric heating tubes 10, thereby heating the material inside the conical tank 1. The temperature can be monitored in real time by a temperature measuring device 15, which facilitates temperature control.

[0026] In this embodiment, two outer screw blades 6 are provided, and the two outer screw blades 6 are distributed on both sides of the rotating main shaft 4, which can effectively enhance the mixing effect. The two ends and the middle part of the two outer screw blades 6 are respectively fixed to the rotating main shaft 4 by connecting rods 13, thereby realizing the fixation of the two outer screw blades 6.

[0027] A temperature measuring hole 14 is provided on the jacket 8, and a temperature measuring device 15 is fixed at the temperature measuring hole 14. By setting the temperature measuring device 15, the temperature of the medium in the jacket 9 can be detected in real time, which facilitates temperature control. A protective cover 16 is provided outside the temperature measuring device 15 to protect the temperature measuring device 15 and prevent it from being damaged during use.

[0028] In order to facilitate the proper discharge of the mixed powder from the discharge port at the lower end of the conical tank 1, at least one fluidizer 17 is provided at the lower end of the conical tank 1. In this embodiment, three fluidizers 17 are evenly distributed in a circumferential array on the conical tank 1. By providing fluidizers 17 at the lower end of the conical tank 1, bridging can be effectively prevented so that the material can be discharged smoothly.

[0029] In this embodiment, six electric heating tubes 10 are evenly distributed in a circumferential array within the jacket 8, which can achieve uniform heating of the medium within the jacket 8, effectively improve the heating effect, and save time.

[0030] The cone angle of the conical tank 1 is A, and the cone angle of the jacket 8 is B. In this embodiment, A=45° and B=50°.

[0031] To facilitate unloading, a star-shaped unloader 18 is connected to the discharge port at the lower end of the conical tank 1, which discharges the mixed material from the conical tank 1 by means of a rotating impeller.

[0032] To prevent heat loss, the conical tank 1 is equipped with insulation cotton 19, which can achieve a good heat preservation effect.

[0033] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention.
