Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery recycling, in particular to an electrolyte collection device for recycling lithium batteries. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the very 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, and lithium batteries need to be recycled after use.

[0003] However, existing lithium batteries need to be crushed after recycling. During the crushing process, the electrolyte cannot be fully leached out, and most of the crushed lithium batteries are mixed with the electrolyte, resulting in impurities in the electrolyte, which cannot achieve the recycling effect. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides an electrolyte collection device for recycling lithium batteries, which is capable of fully squeezing out the electrolyte inside the lithium battery through an extrusion plate and completely decomposing the electrolyte through a second filter screen to achieve a recycling effect, thereby solving the above-mentioned technical problems.

[0008] Preferably, the first motor is rotatably connected to the crank.

[0009] Through the above technical solution, the output shaft of the first motor is connected to the crank through one end passing through the mounting plate, that is, when the first motor is started, the first motor can drive the end of the crank to rotate around the output shaft of the first motor.

When the connecting rod swings, it can slide inside the slide groove through the slider and drive the extrusion plate to move. In this way, the electrolyte inside the lithium battery can be squeezed out by the mutual approach of the two extrusion plates, until the qualified lithium battery passes through the first filter.

[0014] Preferably, a second motor is fixedly mounted on the upper end of the pad, and the second motor is rotationally connected to the gear.

[0015] Through the above technical solution, after the electrolyte passes through the first filter and flows into the inside of the drum, the second motor is started, and the second motor drives the gear to rotate. When the gear rotates, it can drive the gear ring meshing with it to rotate, and the gear ring can drive the drum to rotate, so that the electrolyte can be mixed and rotated.

[0016] Preferably, a second filter screen is arranged inside the drum, and the swing rod is located on the upper surface of the second filter screen.

[0017] Through the above technical solution, as the drum driven by the second motor rotates the electrolyte, the fixed rod, i.e., the two rocker arms at the upper end, can further sweep the electrolyte on the second filter screen inside the drum when the drum rotates, so that the electrolyte is fully subdivided. The qualified electrolyte flows to the lower end through the second filter screen, thereby achieving the effect of energy recovery, and then the solenoid valve is controlled to open to allow the electrolyte to flow out from the liquid outlet pipe.

In this way, the electrolyte inside the lithium battery can be fully squeezed out by the mutual approach of the two extrusion plates, until the qualified lithium battery passes through the first filter and falls into the inside of the drum.

[0020] 2. The utility model sets a second motor and a second filter and other components. By starting the second motor, the second motor drives the gear to rotate.
