[0034] The present invention will be further described below with reference to the accompanying drawings:
[0035] like Figures 1-3As shown, a cathode material premixing device includes a main body 1. A feed inlet 6 is provided on the side wall of the main body 1. At least three support legs 2 are evenly distributed at the bottom of the main body 1 to provide stable support. An inner cavity 3 is provided inside the main body 1, and the feed inlet 6 communicates with the inner cavity 3. A heating module is provided at the bottom of the inner cavity 3, and a discharge port 24 is also provided through the bottom of the inner cavity 3. A bottom valve 14 is fixedly installed on the discharge port 24 to facilitate the output of the material after mixing in the inner cavity 3. The bottom valve 14 can control the opening and closing of the discharge port 24. A stirring shaft 10 is provided at the top of the inner cavity 3, and several connecting rods 11 are fixedly installed on the stirring shaft 10. A stirring paddle 12 is fixedly installed at the free end of each connecting rod 11. The stirring rods and stirring paddles 12 can achieve mixing of the material in the inner cavity 3, improving mixing efficiency. A spraying device 5 is fixedly installed on the stirring shaft 10. The main body 1 is equipped with a connecting ring 4 and a spraying device 5, which is provided with a spraying chamber 13. The spraying chamber 13 consists of multiple chambers that are evenly distributed around the circumference of the spraying device 5 and are interconnected. A limiting ring 25 is provided at the opening of the spraying chamber 13. The limiting ring 25 is connected to the spraying chamber 13 by a threaded connection. In this way, the spraying amount of the agent can be controlled by the limiting ring 25. The spraying amount can also be adjusted by replacing the limiting ring 25 with a different aperture. The connecting ring 4 is provided with a through hole 21. One end of the through hole 21 is connected to the spraying chamber 13. The main body 1 is equipped with a motor 7 and a feeding hopper 8. The motor 7 is a permanent magnet motor. The permanent magnet motor is stable in operation and has a low failure rate. It can not only provide stable power output for the equipment, but also reduce maintenance and repair costs and improve production efficiency. The output end of the motor 7 is connected to the stirring shaft 10. The output end of the feeding hopper 8 is connected to the spraying chamber 13 through the through hole 21 on the connecting ring 4.
[0036] Specifically, the output end of the feeding hopper 8 is provided with a conveying pipe 9, and the free end of the conveying pipe 9 is provided with a rotating ring 16. The rotating ring 16 has a channel 20. The rotating ring 16 is rotatably mounted on the connecting ring 4. The conveying pipe 9 is connected to the through hole 21 through the rotating ring 16. The spraying device 5 and the connecting ring 4 are both provided with flow channels 15, and the flow channels 15 are positioned opposite each other. The flow channel 15 on the spraying device 5 is connected to the spraying chamber 13, and the flow channel 15 on the connecting ring 4 is connected to the through hole 21. In this way, the agent to be added can be transported to the spraying device 5 through the conveying pipe 9, and the agent can be sprayed by the spraying device 5.
[0037] The connecting ring 4 has a groove 18 on its outer wall, and the rotating ring 16 is located in the groove 18. A ball bearing 17 and a sealing strip 19 are respectively provided between a set of relatively mating surfaces of the rotating ring 16 and the groove 18. This can reduce the friction between the connecting ring 4 and the rotating ring 16 when they rotate relative to each other, reduce the wear of parts, and extend the service life of the equipment. The sealing strip 19 can prevent the agent from leaking from the joint. The sealing strip 19 is made of high temperature and corrosion resistant silicone material and is vulcanized into one piece with the rotating ring 16.
[0038] The heating module located at the bottom of the inner cavity 3 includes a heating block 22 and multiple heating rods 23. The heating block 22 is fixedly located at the bottom of the inner cavity 3 and is preferably made of copper or aluminum, which have good thermal conductivity. The multiple heating rods 23 are embedded inside the heating block 22. This increases the heating area and achieves uniform heating of the material.
[0039] It should be noted that in this embodiment, the vertical height of the inlet 6 from the bottom surface of the inner cavity 3 is not less than the vertical height of the spraying device 5 from the bottom of the inner cavity 3. This setting can prevent the agent from being thrown out of the inlet 6 due to excessive rotation speed of the spraying device 5. Although the inlet 6 is generally equipped with a shielding component, in some special working conditions, it is still necessary to add the agent to the inner cavity 3 during the mixing process. Therefore, by limiting the height of the inlet 6 and the spraying device 5, the situation of the agent being thrown out of the inlet 6 can be avoided.
[0040] The working process of this embodiment is as follows: During operation, firstly, an appropriate amount of solvent is added to the inner cavity 3 through the feed inlet 6, and then the feed inlet 6 is closed. Then, the power supply to the heating rod 23 and the motor 7 is turned on. After the power supply is turned on, the heating rod 23 will heat the heating block 22, which in turn heats the solvent in the inner cavity 3 to improve the mixing efficiency. After the power supply is turned on, the motor 7 will drive the stirring shaft 10 to rotate. After the stirring shaft 10 rotates, the connecting rod 11 and the stirring paddle 12 will stir the solvent. The spraying device 5 and the connecting ring 4 will rotate synchronously with the stirring shaft 10. At this time, the agent is added to the hopper. The agent will enter the spraying chamber along the conveying pipe 9. The agent entering the spraying chamber 13 will be thrown out from the limiting ring 25 at the opening of the spraying chamber 13 under the action of centrifugal force, so as to achieve uniform spraying of the agent and improve the mixing efficiency.
[0041] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
