Problems solved by technology

[0003] When current lithium batteries are recycled, it is often necessary to flatten and crush the lithium batteries to extract the metal ions inside the batteries. However, the storage of batteries is huge, and generally more batteries are gathered together and poured into crushing. Dismantling, at this time, too many lithium batteries may be blocked when they are crushed and dropped, and the falling and transported batteries may be attached to each other, making it difficult for the crushing mechanism to completely flatten and crush the batteries, reducing the efficiency of subsequent battery recycling , and the recovered battery waste is difficult to collect again, which increases the difficulty and inconvenience of the operator's finishing work; when the crushed lithium battery is recovered for metal ions, the lithium battery is generally stirred to mix the metal ions Separation and collection, but a single stirring method cannot well squeeze out the metal ions inside the lithium battery, thereby reducing the utilization rate of metal ion recovery and reducing the recovery efficiency of the device

Embodiment 1

[0047] Example 1, such as figure 1 and Figure 6 As shown, when the lithium battery enters the inside of the material guide tube 19 through two sets of inclined material guide frames 18, the second pulley 14 can be driven to rotate by the start of the biaxial motor 20, and the rotation of the second pulley 14 and the belt 13 The linkage cooperation with the first pulley 12 forces the two sets of first pulleys 12 to drive the feed pipe 19 to rotate under the cooperation of the bearings, so that the lithium battery entering the inside of the feed pipe 19 is stirred and pulverized under the cooperation of the spiral stirring rod, and With the cooperation of the hemispherical guide seat, the lithium battery is evenly discharged from the bottom of the material guide tube 19, which improves the crushing accuracy of the lithium battery and the recovery effect of subsequent metal ions.

Embodiment 2

[0048] Example 2, such as figure 1 and Figure 8 As shown, after the lithium battery is rolled by two groups of rolling rollers 604, it penetrates into the filter mesh groove 601 from the filter mesh plate 602. At this time, the lithium battery in the filter mesh groove 601 is subjected to secondary Filtration promotes the metal ions of the lithium battery to be separated from the lithium battery very well. At this time, the connection and fixation of the elastic hook and the hanging ring can be canceled, and the filter mesh groove 601 can be canceled as a whole by the suction and fixation of the magnetic suction ring and the magnetic suction groove. The filter mesh tank 601 is taken out separately, and the waste materials received by the filter mesh groove 601 are recovered and processed, so as to increase the operability and convenience of the recycling process after the lithium battery is separated.

[0049] To sum up: the device uses the secondary crushing function and th...

Abstract

The invention discloses a device and process for disassembling lithium batteries and recycling metal ions. The device comprises two sets of racks, the bottoms of the sides, close to each other, of the two sets of racks are provided with mounting grooves, the tops of the two sets of racks are provided with mutually-connected material guiding grooves, the tops of the material guiding grooves are provided with mutually-communicated feeding ports, a double-shaft crushing mechanism is arranged at the tops of the interiors of the feeding ports, a fixing frame is arranged in the middles of the two sides of the interior of each material guiding groove, and inclined material guiding frames are arranged at the two sides of the top of each fixing frame; the lithium batteries entering from the feeding ports are pre-crushed through the double-shaft crushing mechanism, the crushed lithium batteries are evenly guided from the two sides through the two sets of inclined material guiding frames, and secondary crushing work is carried out through rotary stirring of material guiding pipes, stirring blades and crushing rollers in the period; and the disassembly rate of the lithium batteries and the subsequent metal ion recovery effect are further improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery recovery, in particular to a device for dismantling and recovering metal ions from a lithium battery and a process thereof. Background technique [0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from rechargeable batteries. Lithium-ion batteries are different from lithium-ion polymer batteries because the chemical properties of lithium metal are very active. , so that the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. After lithium batteries are used, they are generally crushed to extract metal ions and other elements inside the battery for recycling. It will be reprocessed and used later. [0003] When current lithium batteries are recycled, it is often...
