Description

Technical Field

[0001] The invention relates to a powder removal device, in particular to a waste battery recycling and powder removal device. Background Art

[0002] Waste batteries are batteries that have been used and discarded. Waste batteries are seriously harmful to the environment and should be collected and recycled. Whether in the atmosphere or buried deep underground, the heavy metal components of waste batteries will leak out with the seepage, causing groundwater and soil pollution, which will seriously endanger human health over time.

[0003] Patent announcement number CN113113691A discloses a dry de-powdering device for waste lithium-ion battery separators, the de-powdering device comprises a frame, a feeding device and a de-powdering device; the feeding device comprises a feeding hopper, a screw feeder and a feeder driving motor, the screw feeder is arranged above the frame, and the feeding hopper is arranged above the screw feeder; the de-powdering device comprises a de-powdering screen drum, a de-powdering paddle, a de-powdering device housing, a de-powdering paddle driving motor, a transmission belt, a discharging hopper and a powder outlet; the de-powdering screen drum is installed in the housing of the de-powdering device, the end of the screw feeder is connected to the de-powdering screen drum, and the other end is connected to the coaxially arranged feeder driving motor, the de-powdering paddle is installed in the de-powdering screen drum, and the de-powdering paddle driving motor is vertically installed on the side of the housing of the de-powdering device. The de-powdering equipment is provided with a de-powdering paddle in the de-powdering device. The blade structure and arrangement design on the de-powdering paddle can not only realize the continuous upward lifting of the waste lithium-ion battery diaphragm, but also avoid the entanglement between the diaphragms. When the diaphragm enters, the extrusion and friction between the diaphragms and the diaphragm and the sieve drum are utilized to realize the separation of the black powder and the diaphragm, and the black powder falls under the action of gravity and is thrown out of the sieve drum under the action of centrifugal force. The fallen black powder is collected at the bottom powder outlet. The whole diaphragm de-powdering process does not require the use of water, thus protecting the environment and reducing costs.

The second top plate 1804 will contact the connecting plate 1802 when it moves downward.

[0035] When it is necessary to crush and remove powder from the discarded batteries, the staff pours a certain amount of discarded batteries into the crushing box 2, and then starts the servo motor 6. The output shaft of the servo motor 6 rotates to drive the first rotating shaft 3 on the right to rotate, and the rotation of the first rotating shaft 3 on the right drives the gear 5 on the right to rotate. Under the action of the mutual meshing of the two gears 5, the first rotating shaft 3 on the left rotates, and the rotation of the first rotating shaft 3 on both sides drives the crushing drum 4 to rotate to crush the discarded batteries. Under the action of the filter plate 7, larger pieces can be filtered and left in the crushing box 2 for further crushing, and smaller pieces of discarded batteries fall into the de-powdering box 8. The rotation of the first rotating shaft 3 on the left drives the first top plate 1703 to rotate, and the first top plate 1 703 rotates and squeezes the sliding plate 1702 to move upward, and the sliding plate 1702 moves upward to drive the slider 11 to slide upward on the slide groove 9 and the first guide rod 10, and the first elastic member 1701 is compressed accordingly, and the slider 11 slides upward to drive the powder removal frame 12 to move upward, and the screen 13 moves upward accordingly.

The powder then passes through the screen 13 and falls into the powder removal box 8, and then falls out through the discharge port 801. The staff uses a tool to fix the container at the bottom of the powder removal box 8 and align it with the discharge port 801. The powder falls into the container for centralized collection. After the waste batteries in the powder removal box 8 are de-powdered, the staff turns off the servo motor 6 to stop the crushing and de-powdering operations. Then the staff starts the cylinder 1803. The extension end of the cylinder 1803 extends to drive the second top plate 1804 to move downward. Since the bottom of the second top plate 1804 is an inclined surface, the second top plate 1804 moves downward and squeezes the connecting plate 1802 to move to the left through the inclined surface. The connecting plate 1802 moves to the left and drives the slide bar 14 to slide to the left, and the second elastic member 1801 is pressed accordingly. The sliding bar 14 slides to the left, driving the pushing plate 15 to move to the left, pushing the waste batteries after de-powdering into the discharging hopper 16, and the waste batteries fall out through the discharging hopper 16, and the staff uses a container to collect them. After all are pushed out, the staff controls the telescopic end of the cylinder 1803 to shorten, and the shortening of the telescopic end of the cylinder 1803 drives the second top plate 1804 to move upward and reset, and no longer squeezes the connecting plate 1802 through the inclined surface. The second elastic member 1801 is reset accordingly, driving the connecting plate 1802 to move to the right and reset, and the connecting plate 1802 moves to the right and drives the sliding bar 14 to slide to the right and reset, and the sliding bar 14 slides to the right and drives the pushing plate 15 to move to the right and reset. After use, the staff closes the cylinder 1803 and stops the operation.

[0039] The connecting plate 1802 moves to the left, driving the third top plate 2002 to move to the left. The third top plate 2002 moves to the left to squeeze the mounting block 2001 and drive the first baffle 1903 to slide downward. The third elastic member 1904 is compressed accordingly. The first baffle 1903 slides downward to open the discharge hopper 16. The waste batteries after de-powdering are dropped and collected by the staff. The connecting plate 1802 moves to the right and resets, driving the third top plate 2002 to move to the right and reset, and no longer squeezes the mounting block 2001. The third elastic member 1904 is reset accordingly, driving the first baffle 1903 to slide upward and reset to block the discharge hopper 16 again, thereby preventing the crushed waste batteries from falling through the discharge hopper 16 during the de-powdering process and affecting the de-powdering.
