Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery recycling, and in particular to an immersion discharge device for lithium battery recycling. Background Art

[0002] Lithium-ion batteries have become an ideal power source for the new generation of electric vehicles due to their excellent performance. The widespread use of lithium-ion batteries will inevitably bring a large number of waste batteries. If they are discarded at will, it will not only cause serious pollution to the environment, but also a waste of resources. Lithium-ion batteries contain more metal resources such as lithium, aluminum, and iron, which need to be recycled. For lithium-ion battery recycling, they must first be immersed and discharged.

[0003] The current recycling of waste lithium batteries is still in its early stages, and the relevant supporting equipment is still not perfect. In actual operations, staff are often required to manually place the waste lithium batteries into salt water, wait for them to be fully discharged, and then use tools to remove the waste lithium batteries from the salt water and place them in a net bucket, and then drain the remaining water on the outside. The whole process is inefficient and the level of automation is low. Summary of the invention

[0004] The present invention relates to an immersion discharge device for lithium battery recovery, which solves the problem that the existing waste lithium battery recovery operation is just in its infancy and the supporting equipment is not perfect. It is usually necessary to manually place the waste lithium batteries in salt water, wait for them to be fully discharged, and then use tools to fish the waste lithium batteries out of the salt water into a net bucket to drain the residual water on the outside, resulting in low efficiency.

[0006] Furthermore, the rotating wheel frame is rotatably connected to the immersion tank, a large pulley is provided at the end of the rotating wheel frame, a small pulley is provided on the driving shaft of the motor, and the small pulley is transmission-connected to the large pulley through a synchronous belt.

[0007] Furthermore, U-shaped grooves are symmetrically arranged around the outside of the rotary wheel frame. Connecting blocks are provided at both left and right ends of the steel mesh bag, and the connecting blocks are connected within the U-shaped grooves.

[0008] Furthermore, C-shaped strips are provided on the left and right inner sides of the immersion water tank. The openings of the C-shaped strips face upward, and the angle of the C-shaped strips is 270 degrees. When the rotary wheel frame drives the steel mesh bag to move to the bottom, the C-shaped strips are in sliding contact with the ends of the connecting blocks.

[0009] Furthermore, a track frame is provided at the top of the main body. Roller A is symmetrically arranged at both left and right ends of the feeding slide seat, and roller A is in rolling contact with the track frame. Roller B is symmetrically arranged at both left and right ends of the discharging slide seat, and roller B is in rolling contact with the track frame.

[0010] Furthermore, the front end of the X-shaped frame is fixedly connected to the feeding slide seat, and the rear end of the X-shaped frame is fixedly connected to the discharging slide seat. When the feeding slide seat is located at the top of the loading platform, the discharging slide seat is at the top of the immersion water tank. When the feeding slide seat is at the top of the immersion water tank, the discharging slide seat is at the top of the discharging platform.

[0011] Furthermore, the cylinder block of the hydraulic cylinder is connected to the track frame, the piston rod of the hydraulic cylinder is connected to the feeding slide seat, a lifting handle is provided at the top of the steel mesh bag, and the lifting handle is magnetically attracted and connected within the electromagnet.

[0012] Furthermore, the bottom of the support frame is fixedly connected to the top of the electromagnet. A suspension rope is connected to the top of the solid ball, and the top end of the suspension rope is connected within the top of the support frame. The three solid balls are arranged within the support frame.

[0013] The present invention provides an immersion discharge device for lithium battery recycling, which has the following beneficial effects:

[0014] When the present invention is in use, the motor drives the rotary wheel frame to rotate within the immersion water tank. The bottom of the rotary wheel frame is immersed in the salt water. When the notch of the U-shaped groove faces upward, the connecting blocks at both ends of the steel mesh bag are placed within the U-shaped groove. The rotary wheel frame drives the steel mesh bag to move, and the notch of the U-shaped groove gradually changes from the upward state to the downward state, and then changes back to the upward state. When the notch of the U-shaped groove faces downward, the C-shaped strip contacts the connecting block, which plays a role in limiting the connecting block and preventing the connecting block from separating from the U-shaped groove, enabling the rotary wheel frame to continuously drive the steel mesh bag to move. The lithium batteries within the steel mesh bag are immersed in the salt water to achieve the discharge effect. By driving the steel mesh bag to move through the rotary wheel frame, continuous lithium battery water inlet and discharge operations are realized, improving the lithium battery discharge treatment efficiency; when the notch of the U-shaped groove faces upward, the C-shaped strip separates from the connecting block, and the connecting block is released from the limit, so that the steel mesh bag can be taken and placed.

[0015] In addition, the hydraulic cylinder drives the loading slide to move back and forth, and the loading slide drives the unloading slide to move back and forth synchronously through the X-shaped frame; when the hydraulic cylinder drives the loading slide to move to the front end, the loading slide is above the loading platform, and the steel mesh bag storing the lithium batteries to be discharged is placed on the loading platform. The winch at the top of the loading slide drives the electromagnet to move downward, so that the electromagnet is attracted to the steel mesh bag on the top of the loading platform, and the steel mesh bag is lifted to a specified height by the winch; at the same time, the steel mesh bag storing the discharged lithium batteries moves to the top of the rotating wheel frame, the unloading slide moves above the rotating wheel frame, and the winch at the top of the unloading slide drives the electromagnet to move downward, so that the electromagnet is attracted to the steel mesh bag on the top of the rotating wheel frame, and the steel mesh bag is lifted to a specified height by the winch; the hydraulic cylinder drives the loading slide to move to the rear end, the loading slide is above the rotating wheel frame, the winch at the top of the loading slide drives the steel mesh bag to move downward, so that the connecting block is located in the U-shaped groove, the electromagnet is powered off, and the winch drives the electromagnet to reset upward automatically; at the same time, the unloading slide moves above the unloading platform, the winch at the top of the unloading slide drives the steel mesh bag to move downward, places the steel mesh bag on the unloading platform, the electromagnet is powered off, and the winch drives the electromagnet to reset upward automatically; the lithium battery loading and unloading operations are carried out synchronously through the loading slide and the unloading slide, effectively saving time and further improving the lithium battery discharge treatment efficiency.

[0016] In addition, when the electromagnet stops moving back and forth, due to inertia, the electromagnet will swing, and the solid ball in the support frame will swing accordingly, thus achieving the effect of swing damping, which can effectively reduce the swing amplitude of the electromagnet and make the electromagnet return to a stable state faster.

[0039] The working principle of this embodiment: First, place the steel mesh bag 2 storing the lithium batteries to be discharged on the loading platform 101. The hydraulic cylinder 9 drives the feeding slide seat 6 to move to the front end. The feeding slide seat 6 is above the loading platform 101.
