A safe and automatic dismantling device for controllable discharge of waste hard-shell lithium-ion power batteries

Abstract

The invention belongs to the technical field of machinery, in particular to a controllable discharge safety automatic disassembly device for a waste hard shell lithium ion power battery, Including anexhaust gas filtration tank, an Intake pipe, a check valve, an air cylinder, an Outlet pipe, a suction pipe first pipe, case, a pipe fixing plate, hose, a second pipe, a solenoid valve, a first motor,a slider, a nitrogen tank, a transverse plate, a mounting plate, a funnel, a storage plate, support legs, a waste liquid collection bottle, a filter screen, a support column, a first pressure plate, asecond pressure plate, a case door, a second motor a amounting plate , second motor, a aguide rail mounting pl ate, guide rail, screws, a cutting knife and a screw mounting plate. The disassembly efficiency of the invention is high, As that liquid nitrogen cool the cutting place during the cutting of the power battery, the occurrence of the spontaneous combustion of the battery caused by excessive temperature during the cut is avoided, the battery explosion is avoided, the battery is cut in the box body, the personal safety of the dismantling personnel is facilitated, and the gas filtering mechanism avoids the pollution of the environment caused by the waste gas during the dismantling.

Description

technical field [0001] The invention belongs to the technical field of machinery, and specifically relates to a controllable discharge safe automatic dismantling device for waste and old hard-shell lithium-ion power batteries. Background technique [0002] Hard-shell lithium-ion power battery is the power source that provides power for tools. It refers to one of the batteries that provide power for electric vehicles, electric trains, electric bicycles, and golf carts. With the rapid development of new energy vehicles, waste power The recycling, dismantling and reuse of lithium-ion batteries has become a problem that cannot be ignored in the process of new energy development. After recycling, waste power lithium-ion batteries need to be disassembled to reduce the pollution of the battery to the environment. The electrodes of the disassembled lithium-ion batteries , casing, electrolyte, etc. can still be reused, so the dismantling of lithium-ion power batteries is of great sig...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a controllable discharge safe automatic dismantling device for waste hard-shell lithium-ion power batteries in order to solve the above problems. A cutting mechanism is provided to fix the power battery to be dismantled on the first pressure plate and the second pressure plate. Between, and then start the first motor and the second motor, the second motor drives the screw to rotate, so that the slider moves, and then the cutting knife cuts the power battery, and the disassembly efficiency is high. Cool down the temperature at the cutting place, avoiding the occurrence of spontaneous combustion of the battery caused by excessive temperature during cutting, and avoiding the explosion of the battery, and the battery cutting is located in the box, which is conducive to the personal safety of the dismantling personnel; the gas filter mechanism is set to cut the power battery The exhaust gas generated is drawn out from the box by the fan, and the extracted gas is sent into the gas filter box; the polluted gas in the exhaust gas is absorbed by the alkaline solution in the gas filter box, and then the filtered gas is discharged from the exhaust pipe, avoiding The exhaust gas pollutes the environment during dismantling, and at the same time avoids the inhalation of toxic gases by the dismantling personnel, which protects the health of the dismantling personnel. At the same time, the device contains a filter screen and a waste liquid collection bottle, which can cleanly and effectively collect the power battery. electrolyte
