Description

Technical Field

[0001] The utility model relates to the technical field of waste battery recycling, in particular to a punching machine for recycling waste batteries. Background Art

[0002] Waste lead-acid batteries are composed of positive and negative plates, electrolyte, separator, battery tank, and some parts such as terminals, exhaust plugs, connecting strips, etc. Among them, the electrolyte is mainly sulfuric acid. The existing way to recycle lead-acid batteries is to directly mechanically crush the lead-acid batteries, and then decompose the various parts through hydraulic sorting. Direct mechanical crushing will be mixed with more impurities in the electrolyte, which increases the cost of electrolyte recovery. Therefore, in order to reduce the electrolyte recovery effect, it is necessary to use a hydraulic puncher to punch holes in the outer shell of the lead-acid battery before mechanical crushing to discharge the electrolyte in the lead-acid battery through the holes. The existing puncher punches from top to bottom. During the punching process, the punching piece is easy to touch the bus. Due to the large thickness of the bus, it is necessary to apply a large pressure to the battery during the punching process. The strength requirements of the punching piece are high, and the punching efficiency is low.

[0003] The patent document with application number CN202223109404.3 discloses a puncher for recycling used batteries, which makes a hole at the bottom of the battery, and the slurry in the battery is discharged through the hole at the bottom of the battery. However, during the process of discharging the slurry inside the battery, the air outside the battery also enters the battery through the hole at the bottom of the battery, so the discharge efficiency of the slurry inside the battery is low.

[0004] The patent document with application number CN202123094437.0 discloses a lead-acid battery slurry recovery device, which first cuts the lead-acid battery and then recovers the slurry of the lead-acid battery of the electric vehicle. During operation, the lead-acid battery is transported to the stop plate by a conveyor belt, and then the motor is started. The motor drives the rotating shaft to rotate and then drives the paddle plate to rotate. During the rotation process, the paddle plate will paddle the lead-acid battery located on the stop plate, so that the lead-acid battery slides to the two cover plates, and then the telescopic cylinder is controlled to drive the pressure plate to press down, and the vertical plate is against the lead-acid battery, so that the cover plate presses down the spring, the lead-acid battery contacts the cutter and is cut by the cutter, and the slurry in the lead-acid battery flows into the liquid collection box along the cutter, and then the telescopic cylinder is controlled to rise, the lead-acid battery rebounds under the action of the spring, and the limit block is used to block the position to restore the cover plate to a horizontal state, and then the next lead-acid battery is driven by the paddle plate to slide along the cover plate, and the cut lead-acid battery is pushed into the solid collection box, and the recovered solid is taken out through the collection door for use. After the device cuts the battery, the slurry inside the battery only relies on gravity to flow downward, so the outflow efficiency of the slurry inside the battery is low. Utility Model Content
