[0035] A rotatable bracket 5 is arranged inside the annular fixing frame 4, and a ring body 6 is fixedly connected to the bracket 5. The ring body 6 is rotatably connected to the annular fixing frame 4, and a nozzle assembly 7 that can change the jet amount of the inlet pipe 2 is arranged on the ring body 6. The raw material is added to the airflow mill 1 from the feed channel 3, and at the same time, the motor 10 is turned on. During the operation of the motor 10, the motor 10 will drive the bevel gear 2 12 to rotate through the connecting shaft 11, and the meshing transmission between the bevel gear 2 12 and the bevel gear 1 9 is used to drive the bracket 5 to rotate, and then drive the ring body 6 to rotate, select a suitable nozzle, and align the nozzle with the inlet pipe 2. In this process, the protective sleeve 8 is used to seal the transmission parts, and the sealing plate 24 is used to cover the rotating part of the ring body 6 from above, which can avoid the impact of falling materials on the ring body 6, thereby avoiding the dust environment from affecting the normal switching of the nozzle, and thus facilitating the change of the particle size of the processed finished product by adjusting the nozzle, thereby improving the work efficiency.

One end of the connecting shaft 11 penetrates the airflow mill 1 and extends to the inside of the airflow mill 1. The connecting shaft 11 is rotatably connected with the protective sleeve 8. One end of the connecting shaft 11 is fixedly connected with a bevel gear 2 12, and the bevel gear 2 12 is meshed with the bevel gear 9. The bevel gear 2 12 and the bevel gear 9 are both located in the protective sleeve 8. The motor 10 is electrically connected to the external power supply and is controlled by an external control program.

[0037] The annular fixing frame 4 includes an upper fixing frame 41 and a lower fixing frame 42 . The upper fixing frame 41 and the lower fixing frame 42 are detachably connected to each other. An air intake passage for clamping the air intake pipe 2 is arranged between the upper fixing frame 41 and the lower fixing frame 42 .

[0038] A sealing plate 24 is fixedly connected to the top of the annular fixing frame 4 , and the outer side of the annular baffle 22 is in contact with the nozzle assembly 7 .

[0039] The present invention also discloses a method for processing positive electrode materials based on gas compression technology, which specifically comprises the following steps:

[0040] Step 1: First, add the raw materials into the jet mill 1 through the feed channel 3;

[0041] Step 2: Then, the bracket 5 is rotated to drive the ring body 6 to rotate, and then a suitable nozzle assembly 7 is selected and aligned with the air inlet pipe 2;

[0042] Step 3. Finally, during the processing of the raw materials, the vertical rod 13 is rotated, and the connecting rod 14 is used to drive the feed plate 15 to rotate, so that the rotating feed plate 15 is used to beat the added raw materials, and at the same time, the rotating scraper 25 is used to clean the raw materials on the sealing plate 24 and the annular baffle 22.

[0043] Embodiment 2

[0044] Based on Example 1, see Figure 2-Figure 4 and Figure 8 shown.

[0045] The jet mill 1 is provided with a rotatable vertical rod 13 , to which a connecting rod 14 is fixedly connected, to which a feeding plate 15 is fixedly connected, and the feeding plate 15 is arranged in an inclined manner.

[0046] The jet mill 1 is fixedly connected with a support rod 16, and a protective sleeve 2 17 is fixedly connected to the support rod 16. The protective sleeve 2 17 is rotatably connected to the vertical rod 13, and a bevel gear 3 18 is fixedly connected to the vertical rod 13. The outside of the jet mill 1 is fixedly connected with a motor 2 19, and the output end of the motor 2 19 is fixedly connected with a shaft 20, one end of which passes through the jet mill 1 and extends to the inside of the jet mill 1, and the shaft 20 is rotatably connected to the protective sleeve 2 17, and a bevel gear 4 21 is fixedly connected to one end of the shaft 20, and the bevel gear 4 21 is meshed with the bevel gear 3 18, and the bevel gear 4 21 and the bevel gear 3 18 are both located in the protective sleeve 2 17. The motor 2 19 is electrically connected to an external power supply and is controlled by an external control program. The raw materials are added to the air flow mill 1 from the feed channel 3, and at the same time, the motor 2 19 is turned on. When the motor 2 19 is working, the motor 2 19 will drive the bevel gear 4 21 to rotate through the shaft 20, and utilize the meshing transmission between the bevel gear 4 21 and the bevel gear 3 18 to drive the vertical rod 13 to rotate, and then drive the connecting rod 14 to rotate, thereby driving the feed plate 15 to rotate; when the raw materials fall from the feed channel 3, they will collide with the rotating feed plate 15, so that the rotating feed plate 15 can be used to beat the added raw materials while changing the original falling trajectory of the raw materials. The beating of the raw materials can not only produce some dust, but also help to disperse the raw materials and facilitate the processing of the raw materials.

[0047] Embodiment 3

[0048] Based on Example 1, see Figure 2-Figure 6 shown.

[0049] An annular baffle 22 is fixedly connected to the inner side of the annular fixing frame 4 via a protruding rod. A through hole 23 is formed through the annular baffle 22 . There are four through holes 23 , and the through holes 23 are aligned with the air intake pipe 2 .

[0050] One end of the vertical rod 13 passes through the protective sleeve 17 and extends to the outside of the protective sleeve 17, and a scraper 25 is fixedly connected to the vertical rod 13. When the raw materials are added to the airflow mill 1 from the feed channel 3, some of the raw materials will fall on the sealing plate 24 and the annular baffle 22. Therefore, when the vertical rod 13 rotates, the scraper 25 will rotate with the vertical rod 13, so that the raw materials on the sealing plate 24 and the annular baffle 22 can be cleaned.

[0051] The top of the annular baffle 22 is flush with the top of the sealing plate 24 , and the scraper 25 is respectively in contact with the annular baffle 22 and the sealing plate 24 .

[0052] Embodiment 4

[0053] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, see Figure 1-Figure 8 shown.

[0054] By using a motor 10 to drive the ring body 6 to rotate and using 8 pairs of transmission parts to seal, and using a sealing plate 24 to cover the rotating part of the ring body 6 from above, the impact of falling materials on the ring body 6 can be avoided, thereby preventing the dust environment from affecting the normal switching of the nozzle, which is beneficial to changing the particle size of the processed product by adjusting the nozzle, thereby improving work efficiency.

[0055] The working principle of the present invention is as follows: raw materials are added to the jet mill 1 from the feed channel 3, and at the same time, the motor 1 10 and the motor 2 19 are turned on;

[0056] When the motor 10 is working, the motor 10 will drive the bevel gear 2 12 to rotate through the connecting shaft 11, and utilize the meshing transmission between the bevel gear 2 12 and the bevel gear 1 9 to drive the bracket 5 to rotate, and then drive the ring body 6 to rotate, select a suitable nozzle, and align the nozzle with the air intake pipe 2. In this process, the protective sleeve 8 is used to seal the transmission parts, and the sealing plate 24 is used to cover the rotating part of the ring body 6 from above, which can prevent the falling material from affecting the ring body 6, thereby preventing the dust environment from affecting the normal switching of the nozzle, which is beneficial to change the particle size of the processed product by adjusting the nozzle, thereby improving work efficiency.

[0057] When the motor 2 19 is working, the motor 2 19 will drive the bevel gear 4 21 to rotate through the shaft 20, and utilize the meshing transmission between the bevel gear 4 21 and the bevel gear 3 18 to drive the vertical rod 13 to rotate, and then drive the connecting rod 14 to rotate, thereby driving the feeding plate 15 to rotate; when the raw materials fall from the feed channel 3, they will collide with the rotating feeding plate 15, so that the rotating feeding plate 15 can be used to beat the added raw materials while changing the original falling trajectory of the raw materials. The beating of the raw materials can not only produce some dust, but also help to disperse the raw materials and facilitate the processing of the raw materials.

[0058] When adding raw materials into the air flow mill 1 from the feed channel 3, some raw materials will fall onto the sealing plate 24 and the annular baffle 22. Therefore, when the vertical rod 13 rotates, the scraper 25 will rotate along with the vertical rod 13, so as to clean the raw materials on the sealing plate 24 and the annular baffle 22.

[0059] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
