Description

Technical Field

[0001] This utility model relates to the field of waste battery recycling, and in particular to a cutting device for recycling plastic parts of waste storage batteries. Background Technology

[0002] Currently, my country has become a major producer and consumer of storage batteries. Waste storage battery pollution is a major environmental problem that urgently needs to be solved. The plastic casings of waste batteries are mostly made of PP or ABS materials. Before recycling, the waste lead-acid batteries are cut in half with the lead column down to 50mm using a cutting machine. The internal lead plates, electrolyte, and heavy metals in the tank are processed separately. The plastic parts are then transported to the first water pressure cleaning tank. Based on the material properties, the plastic parts are separated by buoyancy and crushed into 25mm to 30mm granules.

[0003] For example, patent document CN217862291U discloses a cutting device for recycling plastic parts from waste batteries, including: a frame, a cutting machine, a clamping component, a guide groove, a lead screw, a cover, and a slotting mechanism; the cutting device also includes: a protective shell configured to have a protective space so that a portion of the blade located at the bottom of the worktable is within the protective space; and a storage box configured to have a storage space partially connected to the bottom of the protective space; wherein, a plurality of nozzles are provided along the length direction on the worktable so that the nozzles spray gas into the slot along the slotting direction. The advantage of this application is that it provides a cutting device for recycling plastic parts from waste batteries for collecting cutting waste. In the above-mentioned device, a saw blade is used to cut the waste battery, and then the battery is recycled. However, because the electrolyte and electrode plates inside the waste battery are recycled differently from the plastic of the battery casing, the electrolyte plates, electrolyte, and battery casing should be separated before the plastic is crushed. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for recycling plastic parts of waste batteries in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:
