Description

Battery crushing device Technical Field The disclosure relates to the technical field of battery crushing, in particular to a battery crushing device. Background Compared with other storage batteries, the abandoned lithium ion batteries have larger hazard, potential safety hazards exist in storage and transportation links, fire and explosion accidents often occur, and collected batteries are generally intensively treated by new factories of recycling enterprises, but the whole quality of the battery recycling enterprises in the industries is poor, more than 80% of enterprises are small workshops, the equipment is crude, the process is behind, and a large amount of resource waste and serious environmental pollution are caused by the recycling services of the batteries which are engaged in rough places. Each waste battery recycling net point cannot take some measures to ensure safety even when meeting the waste batteries. Even after the batteries are recovered to manufacturers, many manufacturers do not have special treatment measures for the batteries under the conditions, and only the batteries are subjected to standing treatment or soaking treatment after the problems are found, and the batteries are not subjected to active intervention and then are subjected to subsequent disassembly after a long time. And the whole processing process is not centralized processing, and the battery is required to be transferred for a plurality of times to complete the processing process. No automatic fire control, no temperature, no smoke monitoring, no temperature control, and no special waste water and exhaust treatment device. Environmental pollution and new potential safety hazards may be caused during the transportation process. Some manufacturers will define special disposal areas and isolate the areas by using blast walls. The area of the place is large, the place replacement is inconvenient, and the comprehensive cost is high. In order to solve the technical problems, the safety disposal cabinet for the waste batteries is disclosed in the Chinese patent publication No. CN213052057U, the waste batteries which are primarily judged to be in a B-type warning state are cooled and subjected to temperature sensing and smoke sensing through an explosion-proof air conditioner of a placement area, dangerous gas detection is carried out on the waste batteries which are primarily judged to be in a B-type warning state, the waste batteries which are not abnormal and can be safely placed in the placement area are disassembled after being soaked in a soaking area, the batteries which are abnormally in the B-type dangerous state are directly soaked in the soaking area after being primarily judged to be in the B-type dangerous state, and dangerous gas detection is carried out, the disposal mode greatly improves the safety, the waste batteries are well ventilated through the arrangement of an explosion-proof fan and a ventilation window, the safety is high, waste gases are discharged after being sucked away and treated, the waste water is collected by a waste liquid collecting tank and then is introduced into waste water treatment equipment to avoid polluting the environment, and the disposal concentration of the waste batteries is high in the soaking area, the soaking area and the waste batteries are conveniently transported in a whole way or in a long distance through the manufacturing box type structure. In the actual production process, 1, the current lithium battery pack and the current battery module have different model standards and different battery monomer structure sizes, the current recovery technology only can mechanically disassemble the battery monomer, and the battery pack and the battery module can enter the crusher after being manually disassembled into the monomer, or else, the battery pack and the battery module are easy to fire. 2. The battery recycling closed-loop type industrial chain is imperfect, the full-flow recycling technology of the lithium battery is lacked, and the full-flow recycling process line of the lithium battery is complex and the investment cost is high, so that most recycling enterprises only carry out physical separation of waste lithium batteries and pyrolysis of short Cheng Huishou anode materials, copper and aluminum metals, the recycling process is short, secondary pollution exists, the metal recycling rate is low, and the purity and the value of recycled products are low, so that improvement is needed. Disclosure of Invention The technical problem to be solved by the method is that 1, the current lithium battery pack and the current battery module are different in model standards and different in battery monomer structure and size, the current recovery technology can only mechanically disassemble the battery monomer, and the battery pack and the battery module can enter the crusher only by manually disassembling the battery pack and the battery module into the monomer, or else fire is
