[0002] Lead-acid batteries are a common type of battery, and their electrolyte contains sulfuric acid. During use, charging and discharging, lead-acid batteries will produce some waste acid, which needs to be treated and recycled to reduce the impact on the environment.

[0003] The patent with the patent announcement number CN111799525B relates to a device and a method for recovering waste acid from used lead-acid batteries, including a recovery tank, a liquid discharge pump, and a circulating filtration device. This patent can reduce the floor area of existing waste acid treatment equipment and is easy to control by completing the treatment of waste acid liquid in the recovery tank; by setting a circulating filtration device on the recovery tank, the waste acid liquid in the recovery tank can be filtered repeatedly, which can improve the filtration effect of the acid liquid.

[0004] In the above patent, by setting a circulating filtration device on the recovery tank, the waste acid liquid in the recovery tank can be filtered repeatedly, which can improve the filtration effect of the acid liquid. When taking out the waste acid by crushing the battery, since the waste acid has certain corrosiveness and danger, if the crushing device is not sealed in time, the waste acid will splash out and cause danger, and it is difficult to stop crushing the battery when the crushing device is not sealed.

When the two sliding plates move downward simultaneously, they will push the balance plate downward; Step 3: The two sliding plates will push the balance plate and the moving plate downward. When the moving plate moves downward, it will push the positioning plate to rotate; Step 4: When the positioning plate rotates, it will disengage from the positioning gear. The positioning gear will release the limit on the positioning gear and the crushing wheel, so that the driving device can drive the crushing wheel to rotate.

[0015] The present invention provides a device and a recycling method for the remaining acid of waste lead-acid batteries of new energy vehicles. It has the following beneficial effects: (1) In this invention, the battery is crushed by the crushing device, and the top of the crushing frame is sealed by the cover plate to prevent the battery remaining acid from splashing out of the crushing frame. When the two cover plates completely seal the crushing frame, the two pressing plates will push the moving plate downward. When the pressing plate moves downward, it will push the positioning plate to rotate and release the limit on the positioning gear, so that when the two cover plates do not seal the crushing frame in time, the crushing wheel cannot crush the battery, improving the safety of recycling the battery remaining acid.

[0016] (2) In this invention, when the flat plate and the filter plate rotate, the residual acid in the battery can be separated under the action of centrifugal force. When the flat plate rotates, the flap will press the battery on the flat plate to prevent the battery from detaching from the flat plate. When the rotating shaft rotates, the L-shaped rod will push the movable rod and the elastic rod to move, and the elastic rod will push the battery on the flat plate to move, preventing the unchanged position of the battery from affecting the effect of the residual acid detaching from the battery.

[0017] (3) In this invention, when there are too many batteries on the flat plate, the batteries will push the flap to rotate upward. When the flap rotates to a certain height, it will push the bent rod to move upward. When the bent rod moves upward, it will push the linkage rod and the plug board to release the limit on the bolt. The rotation of the bolt will drive the movable rod and the inclined block to move, so that the movable block will drive the transmission rod to move upward. When the transmission rod drives the limiting plate to rotate upward, the limiting plate will limit the batteries inside the feeding cylinder from continuing to move onto the flat plate, preventing too many batteries from accumulating on the flat plate and affecting the effect of residual acid recovery.

[0018] (4) In this invention, the electric push rod will drive the push plate to move. When the push plate moves, it will push the trapezoidal block and the connecting rod to move downward. When the connecting rod moves downward, it will drive the filter plate and the extrusion rod to move downward. When the extrusion rod moves downward, it will no longer squeeze the inclined plane block, so that the inclined plane block releases the limit on the discharge plate, causing the discharge plate to open the discharge port, and the battery will fall onto the collection frame for collection, thereby improving the separation effect of the battery and the residual acid.

Under the gravity of the battery, it will push the discharge plate 68 to move downward. When the discharge plate 68 moves downward, it will open the discharge port, and the battery will fall into the inside of the collection box 611 through the discharge port. When the motor 61 works, it will drive the scraper 612 to rotate. When the scraper 612 rotates, it will push the remaining acid to be discharged from the bottom of the recycling box 1.
