Description

Technical Field

[0001] This invention relates to electrode material recycling and separation equipment, and particularly to a device for cleaning and recycling the surface coating of electrode waste. Background Technology

[0002] To avoid waste of lithium battery raw materials at various stages of production, it is necessary not only to improve processes and increase raw material utilization, but also to recycle scrap materials. Current electrode scrap recycling processes involve manual cleaning of the scrap materials. A simple water storage tank is purchased, and the electrode material to be cleaned is manually placed into the tank. Then, the cleaning solvent NMP is manually added, and a stick is used to stir the material to improve the cleaning effect. The material is then allowed to stand. After standing, the NMP solution is scooped out with a ladle, and the cleaned electrode waste is removed using pliers. The remaining sediment is the recycled slurry, which is then manually filtered to obtain the final material.

[0003] To address the slow efficiency of existing manual separation methods, some current separation equipment employs mechanical automatic separation systems. Waste is placed in a material frame, which is then mounted on a stirring shaft. The separation process is automated using an electric agitator. However, the process of placing the waste into the material frame is difficult, and the frame, fixed to the stirring shaft, cannot be removed. This makes it challenging to extract the cleaned waste from the separation tank, directly impacting separation efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a device for cleaning and recycling the surface coating of electrode waste.

[0005] The objective of this invention is achieved through the following technical solution: a surface coating cleaning and recycling device for electrode waste, comprising a machine base, a cleaning tank, a tank cover, and a rotary drive mechanism. The tank cover can cover the cleaning tank to form a sealed cleaning cavity. A rotary mounting plate is provided inside the cleaning cavity. Multiple detachable and removable material frames are spaced apart on the rotary mounting plate. Each material frame has elastic limiting structures on both sides to restrict the removal of the material frame from the cleaning cavity. Multiple unlocking cylinders are spaced apart on one side of the machine base corresponding to the cleaning tank, and multiple detection cylinders are spaced apart on the other side of the machine base corresponding to the cleaning tank. Each unlocking cylinder and each detection cylinder corresponds to a set of elastic limiting structures. When the unlocking cylinder moves against the elastic limiting structure, the elastic limiting structure can release the restriction on the removal of the material frame.

[0006] When the unlocking cylinder releases its resistance to the elastic limiting structure, the detection cylinder extends and resists the elastic limiting structure to detect its reset position. The detection cylinder can detect whether the limiting platform has completely moved to directly above the limiting protrusion. If it has not completely moved to directly above the limiting protrusion, it can push the push rod to move, ensuring the limiting platform is completely above the limiting protrusion. This prevents the material frame locking from failing.

[0007] The rotary drive mechanism can drive the rotary mounting plate to rotate within the cleaning cavity.

[0008] As an improvement to the electrode waste surface coating cleaning and recycling equipment of the present invention, multiple limiting protrusions are provided at intervals on both sides of the bottom of the material frame. The limiting protrusions cooperate with the limiting platform to realize the limiting function of the material frame. The material frame can be locked and unlocked through the elastic limiting structure, realizing the fixing and removal of the material frame. After the material frame is removed, it is convenient to take out the waste material in the material frame and put in the new waste material to be cleaned. The material frame can be prepared in advance, reducing the material replacement time and improving the cleaning efficiency.

[0009] As an improvement to the electrode waste surface coating cleaning and recycling equipment of the present invention, the elastic limiting structure includes a push rod and multiple elastic sliders. The multiple elastic sliders are fixed at intervals on the push rod, and the push rod can drive the elastic sliders to generate displacement when it moves. The elastic sliders can achieve elastic displacement, and the elasticity of the return spring is used to achieve locking and reset.

[0010] As an improvement of the electrode waste surface coating cleaning and recycling equipment of the present invention, the rotating mounting plate is provided with multiple fixed blocks at intervals on both sides of each material frame, the push rod passes through the fixed block, the elastic slider is located on one side of the fixed block, a return spring is provided between the elastic slider and the fixed block, and a limiting platform extends horizontally from the upper end of the elastic slider, the limiting platform can restrict the movement of the limiting protrusion.

[0011] As an improvement to the electrode waste surface coating cleaning and recycling equipment of the present invention, when the unlocking cylinder cancels the push rod, the reset spring drives the elastic slider to move, and the limiting platform is located just above the limiting protrusion and restricts the movement of the limiting protrusion;

[0012] When the unlocking cylinder abuts against the push rod, the elastic slider moves with the push rod, the reset spring is compressed, the limiting platform is misaligned with the limiting protrusion, and the movement restriction on the limiting protrusion is lifted.

[0013] As an improvement to the electrode waste surface coating cleaning and recycling equipment of the present invention, the flipping of the tank cover is controlled by a flip cover control drive, and the two ends of the tank cover are respectively provided with a locking block, and the locking block is provided with a hook.

[0014] As an improvement of the electrode waste surface coating cleaning and recycling equipment of the present invention, the machine base is provided with mounting seats at both ends of the tank cover.

A swing arm control cylinder is provided on one side of the cylinder mounting seat. The swing arm control cylinder controls a swing block to rotate.

[0015] As an improvement to the electrode waste surface coating cleaning and recycling equipment of the present invention, the middle part of the swing block is movably connected to the cylinder mounting seat through a bearing and a shaft. The swing arm control cylinder can control the rotation of the swing block, and the rotation of the swing block can separate the hook seat from the hook.

[0016] As an improvement of the electrode waste surface coating cleaning and recycling equipment of the present invention, the flip-top control drive includes a rotary control motor, a reducer and a rotating rod. The slot cover is connected to the rotating rod through a sleeve. The output shaft of the reducer is connected to the rotating rod through a coupling. The rotary control motor drives the reducer to rotate.

[0017] The cleaning tank has multiple bearing seats spaced apart on one side edge, and bearings are provided on the bearing seats. The rotating rod passes through the bearings.

[0018] As an improvement to the electrode waste surface coating cleaning and recycling equipment of the present invention, the tank cover is provided with an NMP exhaust gas discharge pipe, and the bottom of the cleaning tank is provided with a slurry recycling pipe.

[0019] The opening edge of the cleaning tank is provided with an annular sealing groove, and a sealing ring is provided inside the annular sealing groove to seal the gap between the tank cover and the cleaning tank.

[0020] The material frame has a mesh structure, with a frame cover at the top. One side of the frame cover is hinged to the upper edge of the material frame, and the other side of the frame cover has a locking lug. The frame cover also has a handle. The locking lug can be secured with screws, allowing the frame cover to cover the material frame and prevent waste material from escaping during cleaning.

[0021] The beneficial effects of this invention are as follows: The material frame of this invention can be locked and unlocked through an elastic limiting structure, realizing the fixing and removal of the material frame. After removal, it is convenient to remove the waste material inside the material frame and put in new waste material that needs to be cleaned. The material frame can be prepared in advance, reducing the material change time and improving cleaning efficiency. This invention also adopts an openable tank cover, which facilitates the removal of the material frame and the insertion of a material frame filled with unwashed waste material after opening the tank cover.
