Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a lithium battery powder conveying device, which includes:

[0025] The powder storage tank 5 has an air inlet at the top connected to the air outlet of the pneumatic valve 3. The air inlet of the pneumatic valve 3 is connected to one end of the first air supply pipe 10, and the other end of the first air supply pipe 10 is connected to the second air supply pipe 11. The end of the second air supply pipe 11 is connected to the air outlet of the second solenoid valve 12. The air inlet of the second solenoid valve 12 is connected to the air outlet of the high-pressure air pump 1. A pressure gauge 2 is installed on the second air supply pipe 11.

[0026] The bottom of the powder storage tank 5 is connected to the discharge pipe 9. The other end of the second air supply pipe 11 is connected to the air inlet of the first solenoid valve 4. The air outlet of the first solenoid valve 4 is connected to the discharge pipe 9 through a hose.

[0027] In one embodiment, the end of the discharge pipe 9 is connected to a powder conveying pipe 8, and a spiral blade 16 is fixed inside the powder conveying pipe 8. The powder will tumble along the spiral blade 16, thereby suspending the powder and making it easier to convey.

[0028] In one preferred embodiment, an air supply pipe 7 is connected to the powder conveying pipe 8. The air supply pipe 7 is connected to another first solenoid valve 4 and another high-pressure air pump 1, which can inject airflow into the powder conveying pipe 8, thereby increasing the powder flow speed inside the powder conveying pipe 8.

[0029] In one embodiment, an annular tube 6 is nested on the outer side of the powder storage tank 5. An air jet pipe 14 is connected to the inner wall of the annular tube 6. Air jet holes 15 are evenly spaced on one side and at the bottom of the air jet pipe 14. The air jet holes 15 are located inside the powder storage tank 5. The air inlet end of the annular tube 6 is connected to the air outlet end of the third solenoid valve 13. The air inlet end of the third solenoid valve 13 is connected to the first air supply pipe 10. The system includes a high-pressure air pump 1, a pressure gauge 2, a pneumatic valve 3, a first solenoid valve 4, and a powder storage tank. The storage tank 5, the annular pipe 6, the air supply pipe 7, the powder conveying pipe 8, the discharge pipe 9, the first air supply pipe 10, the second air supply pipe 11, the second solenoid valve 12, the third solenoid valve 13, the jet pipe 14, the jet hole 15, and the spiral blade 16 together form a positive pressure conveying mechanism. Opening the third solenoid valve 13 allows the airflow generated by the high-pressure air pump 1 to be sprayed onto the inner wall of the powder storage tank 5 through the jet hole 15, which can reduce powder adhesion to the inner wall of the powder storage tank 5 and also clean the inside of the powder storage tank 5.

[0030] In one preferred embodiment, the jet pipes 14 are angularly distributed about the central axis of the annular pipe 6, which increases the jet range of the jet pipes 14 and thus increases the cleaning area of ​​the inner wall of the powder storage tank 5.

[0031] In one embodiment, the outer wall of the powder storage tank 5 is fixed with a support frame 17 by a support plate 18, so that the powder storage tank 5 can be suspended and fixed.

[0032] In one preferred embodiment, the support plates 18 are distributed at equal angles about the central axis of the powder storage tank 5, which increases the stability of fixing the powder storage tank 5.

[0033] In one embodiment, a feed pipe is provided at the top of the powder storage tank 5, and a sealing cap is threaded onto the top of the feed pipe, through which powder can be fed into the powder storage tank 5.

[0034] In one embodiment, the air inlet of the high-pressure air pump 1 is fixed with a dust filter screen by bolts, which prevents external dust from entering the interior of the powder storage tank 5 and prevents the powder inside the powder storage tank 5 from being contaminated.

[0035] The working principle of this utility model is as follows: When using the lithium battery powder conveying device, first open the pneumatic valve 3 and the second solenoid valve 12, and at the same time close the first solenoid valve 4 and the third solenoid valve 13. Start the high-pressure air pump 1. The high-pressure air pump 1 injects gas into the powder storage tank 5 through the second air supply pipe 11 and the first air supply pipe 10, so that the inside of the powder storage tank 5 is pressurized. When the pressure gauge 2 detects that the inside of the powder storage tank 5 has reached the preset value, close the pneumatic valve 3.

[0036] Then, the first solenoid valve 4 is opened, and the airflow generated by the high-pressure air pump 1 blows the powder inside the discharge pipe 9 into the powder conveying pipe 8 through the second air delivery pipe 11 and the hose. Under the action of the spiral blades 16 inside the powder conveying pipe 8, the powder will tumble along the spiral blades 16, thereby suspending the powder and making it easier to convey the powder.

[0037] When it is necessary to clean the powder on the inner wall of the powder storage tank 5, the third solenoid valve 13 is opened. The airflow generated by the high-pressure air pump 1 enters the interior of several jet pipes 14 through the second air supply pipe 11, the first air supply pipe 10 and the annular pipe 6, and finally sprays onto the inner wall of the powder storage tank 5 through the jet hole 15 to clean the powder off the inner wall of the powder storage tank 5.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
