Problems solved by technology

[0003] Lithium batteries can be crushed without discharging to save time and cost, and the heat generated by lithium battery discharge can also be used in subsequent steps. At present, there are also some crushing equipment for charged lithium batteries. The Chinese invention patent with application number 201611075908.4 discloses a scrap lithium battery. Ion power lithium battery charged crushing combination device, the Chinese invention patent application number 201610748755.9 discloses a crushing device for scrapped lithium ion power batteries, and the Chinese invention patent application number 201611075907.X discloses a scrap power lithium battery Nitrogen protection crushing equipment, the equipment disclosed in the above three patents is to crush the charged lithium battery, but the above three equipments are all sprayed with water after the battery is broken and heated, and waste gas and waste water will be generated in the middle process, and the water in the battery During the discharge heating process, it is easy to decompose into hydrogen and oxygen, and it is easy to explode during the discharge process. The above three devices cannot avoid the discharge of the battery.

Embodiment 1

[0023] Embodiment one, such as figure 1 and 2 , a star-shaped impeller 8 charged lithium battery crusher, including an insulating silo 1 above, a vacuum feeding chamber 2 connected below the insulating silo 1, and a crushing chamber 4 below the vacuum feeding chamber 2 , the bottom of the crushing chamber 4 is a vacuum discharge chamber 7, and the bottom of the vacuum discharge chamber 7 is a vertical discharge port 11, and the vacuum feeding chamber 2 and the vacuum discharge chamber 7 pass through The vacuum tube 14 is connected with a vacuum pump 12. The crushing chamber 4 is filled with protective gas. The vacuum feeding chamber 2 is a cylindrical structure with connection ports on the top and bottom. The inside of the vacuum feeding chamber 2 A star-shaped impeller 8 is provided, and the star-shaped impeller 8 includes a plurality of evenly distributed composite blades 9, the edges of the composite blades 9 are close to the inner wall of the vacuum feed chamber 2, and th...

Embodiment 2

[0025] Embodiment two, such as figure 1 , basically the same as the first embodiment, the difference is that a feeding chamber 3 is connected between the vacuum feeding chamber 2 and the crushing chamber 4, and one side of the feeding chamber 3 is connected with a protective gas The original protective gas pipe 15 of the source, the middle part of one side of the vacuum feeding chamber 2 is connected with the vacuum pumping pipe 14, and the middle part of the other side is connected with a recovery protective gas pipe 16, and one side of the vacuum discharge chamber 7 The middle part is connected to the vacuum pumping pipe 14, and the middle part on the other side is also connected to a recovery protection gas pipe 16. The recovery protection gas pipe 16 communicates with the air inlet of the protection gas circulation pump 13, and the gas outlet of the protection gas circulation pump 13 A reusable protective gas pipe 17 communicating with the other side of the feeding cavity ...

Embodiment 3

[0027] Embodiment three, such as figure 1 , which is basically the same as Embodiment 1 or Embodiment 2, except that the left side of the vacuum feeding chamber 2 is connected to the vacuum pumping pipe 14, and the right side is connected to the recovery protective gas pipe 16, and the vacuum exhaust The left side of the material chamber 7 is connected to the vacuum pumping pipe 14, and the right side is connected to the recovery protection gas pipe 16. The star-shaped impeller 8 in the vacuum feeding chamber 2 rotates counterclockwise, and the vacuum discharge chamber 7 The star impeller 8 rotates clockwise.

[0028] In specific operation, the insulating silo 1 can be made of insulating materials such as outer metal and inner insulating plastic (the silo can be entirely made of insulating materials). Before entering the silo, the charged lithium battery must be dehydrated to prevent moisture from entering the crusher. In the crushing chamber, the crusher vacuumizes the lithi...

Abstract

The invention discloses a star-shaped impeller charged lithium battery crusher. The star-shaped impeller charged lithium battery crusher comprises an upper insulation material bin; the lower part of the insulation material bin is connected with a vacuum feeding chamber; the lower part of the vacuum feeding chamber is provided with a crushing chamber; the lower part of the crushing chamber is provided with a vacuum discharging chamber; the lower part of the vacuum discharging chamber is provided with a vertical material outlet; the vacuum feeding chamber and the vacuum discharging chamber are connected with a vacuum pump through vacuumizing pipes; the crushing chamber is filled with a protective gas; before introduction of materials into the crushing chamber, the vacuum feeding chamber is used for vacuumizing of lithium batteries to be crushed, it is ensured that there is no oxygen in the crushing chamber, the crushing chamber is filled with the protective gas, so that discharging of the lithium batteries in crushing is prevented, and a heating problem in lithium battery crushing process is solved.

Description

technical field [0001] The invention relates to the technical field of lithium battery crushing, in particular to a star-shaped impeller charged lithium battery crusher. Background technique [0002] At present, there are more and more applications of lithium batteries. Compared with lead-acid batteries, the main advantage of lithium batteries is that they are more environmentally friendly. The recovery rate of lithium batteries is relatively high. Lithium batteries need to be crushed during recycling. The battery discharges and generates heat during the crushing process, causing danger, which will increase the steps of the recycling process and increase the cost. [0003] Lithium batteries can be crushed without discharging to save time and cost, and the heat generated by lithium battery discharge can also be used in subsequent steps. At present, there are also some crushing equipment for charged lithium batteries. The Chinese invention patent with application number 201611...
