Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery recycling, and more specifically, to an environmentally friendly lithium battery recycling device. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the extremely active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] The organic electrolytes in lithium-ion batteries, the alkali in nickel-cadmium and nickel-metal hydride batteries, and heavy metals such as copper, an auxiliary material for battery manufacturing, will have a certain impact on the environment if discarded at will. Lithium batteries need to be recycled. The outside of used batteries often contains impurities such as dirt, which is not convenient for direct recycling and needs to be cleaned. The current cleaning method generally involves manually cleaning the dirt on the surface of the lithium battery. However, the manual cleaning method not only increases the labor intensity of workers, but also causes heavy metal infection, posing certain safety hazards.

[0004] After searching, a Chinese patent with authorization announcement number CN212703277U discloses an environmentally friendly lithium battery recycling and utilization device. This structure has the advantages of improving cleaning efficiency, etc., which solves the current problem of lithium battery recycling. After the batteries are collected, the outside of the waste batteries often carries impurities such as mud, which is not convenient for direct recycling and requires cleaning. In the existing technology, when recycling lithium batteries, there is no professional device for cleaning lithium batteries, resulting in poor manual cleaning efficiency.

[0005] However, when this structure is actually used, once the surface of the used lithium battery is damaged, a large amount of heavy metal substances will exist in the wastewater after the lithium battery is cleaned. The structure lacks a structure for treating the wastewater and directly discharges the wastewater through a sewage pipe, which is likely to have an impact on the environment. In view of this, the utility model proposes an environmentally friendly lithium battery recycling device. Utility Model Content

[0011] In order to facilitate the disassembly of the activated carbon adsorption net, preferably, two installation ports are opened on the surface of the filter box, and sealing plates are installed inside the two installation ports by screws. The two activated carbon adsorption nets are fixedly connected to the corresponding sealing plates respectively, and the outer wall of the filter box is connected to a drain pipe.

[0012] The technical effects and advantages of this utility model are:

[0013] 1. By setting up a waste liquid treatment structure, the wastewater generated during the cleaning of lithium batteries will enter the interior of the treatment cylinder, the medicine will be added into the interior of the treatment cylinder through the feeding port, and the medicine and wastewater will be mixed by the stirring blade to accelerate the separation of heavy metals in the wastewater. The wastewater will be transported to the interior of the filter box through the delivery pipe, and will be adsorbed and filtered through two activated carbon adsorption nets before being discharged through the drain pipe. In this way, the purpose of wastewater treatment can be achieved, and the pollution caused by wastewater discharge to the environment can be avoided;

[0014] 2. Add lithium batteries into the processing box through the feed port so that the lithium batteries are on the surface of the conveying rollers. The lithium batteries are transported by the rotation of multiple conveying rollers, and the spray pipe sprays water from the water tank through multiple high-pressure nozzles to clean the lithium batteries on the surface of the conveying rollers.

Since one end of the multiple conveying rollers 5 is provided with a track wheel 6, each two track wheels 6 are jointly installed with a track 7, and then the track 7 drives the two track wheels 6 to cooperate with each other, so that the multiple conveying rollers 5 convey the lithium battery inside the processing box 1. During the transportation process, the soil on the surface of the lithium battery is washed and finally discharged through the discharge port 3;

[0025] It is worth noting that, in this structure, the rotation of the multiple conveying rollers 5 is transmitted by a crawler belt 7 driving two crawler wheels 6 of different sizes, with good tension between them, and no slipping or falling off will occur during transmission.

[0026] In a specific embodiment, as shown in the attached Figure 1 、 4As shown in Figure 5, a waste liquid treatment structure is provided on one side of the treatment box 1, and the waste liquid treatment structure includes a treatment cylinder 10, which is provided on one side of the treatment box 1, and one end of the drain pipe 9 is connected to the treatment cylinder 10.

In order to avoid the impact of direct discharge of wastewater on the environment, this structure is used to treat the cleaned wastewater.

[0028] First, the wastewater generated after cleaning the inside of the treatment box 1 is discharged into the inside of the treatment cylinder 10 through the drain pipe 9. The operator adds drugs for purifying the wastewater, such as sodium sulfide and sodium hydroxide, into the inside of the treatment cylinder 10 through the dosing port 22.
