Description

TECHNICAL FIELD

[0001] The application belongs to the field of solid waste treatment, and particularly relates to a solid waste treatment device for lithium battery processing and production. BACKGROUND

[0002] With the continuous rise of global demand for clean energy, the lithium battery industry is developing rapidly and is widely used in new energy vehicles, energy storage equipment and many other fields. However, a large amount of solid waste is generated during the processing and production of lithium batteries, mainly including battery shells, electrode materials, separators and various chemical substances left over during the production process. If these wastes are discarded at will, they will not only pollute the ecological environment but also pose a potential threat to human health. However, the existing solid waste treatment devices basically do not have a screening structure, which results in a large particle size of the crushed solid waste, increases the decomposition period of the solid waste, and may require secondary crushing treatment, thereby reducing the treatment efficiency of the solid waste.

[0003] A solid waste treatment device is disclosed in Chinese Patent No. CN220048321U. The device can effectively solve the problem that the existing solid waste treatment device does not have a screening structure during the crushing treatment of solid waste, resulting in a large particle size of the crushed solid waste, increasing the decomposition period of the solid waste, and possibly requiring secondary treatment, thereby reducing the treatment efficiency of the solid waste. However, during the processing and production of lithium batteries, if there is a winding deviation or cutting failure during the separator slitting process, long strip-shaped separator waste belts will be generated. The separator itself is a thin film with light and thin texture and high toughness, and is easy to form a continuous silk belt. If such a separator is directly crushed in the crusher, it may be wound on the crushing roller due to its length, thereby affecting the normal use of the crushing roller.

DETAILED DESCRIPTION

[0021] The present application will now be further described in detail in conjunction with the drawings.

[0022] Please refer to Figures 1-15As shown, in this embodiment, a solid waste treatment device for lithium battery processing is provided, which comprises a base 1, a crushing mechanism 2 and a discharge port 25, further comprising a treatment box 3, which is arranged in communication with the feeding end of the crushing mechanism 2, and the top of the treatment box 3 is provided with a feeding port 14, and a first rotating shaft 17 is rotatably arranged in the treatment box 3, and the first rotating shaft 17 is driven by a first motor 10, a plurality of cleaning rod assemblies are arranged along the length direction of the first rotating shaft 17 at intervals, each cleaning rod assembly comprises a plurality of hook rods 4 arranged at intervals along the circumference of the first rotating shaft 17, and the plurality of hook rods 4 are arranged opposite to the feeding port 14, and a mounting block 19 and a guide block 20 are fixedly arranged in the treatment box 3 opposite to the first rotating shaft 17, a plurality of cutting grooves 23 are arranged in the mounting block 19 opposite to the plurality of cleaning rod assemblies, and the plurality of cutting grooves 23 are arranged one-to-one corresponding to the plurality of cleaning rod assemblies, and a cutting assembly 9 for cutting the long strip-shaped separator on the hook rod 4 is arranged in the cutting groove 23.

[0023] Specifically, in this embodiment, the long strip-shaped separator waste belt generated by the lithium battery separator slitting enters the treatment box 3 from the feeding port 14 at the top of the treatment box 3 (the feeding port 14 is arranged opposite to the hook rod 4 to ensure that the waste belt can be effectively contacted by the hook rod 4), and the first motor 10 is controlled by an external control device to drive the first rotating shaft 17 to rotate, thereby driving the plurality of cleaning rod assemblies to rotate synchronously, and the rotating hook rod 4 will directly contact and hook the entering long strip-shaped separator waste belt. Since the separator waste belt is light and thin and in the form of continuous ribbon, the circumferential interval distribution and rotating motion of the hook rod 4 can effectively "grasp" the waste belt, avoiding its floating or accumulation in the treatment box 3. With the continuous rotation of the hook rod 4, the long strip-shaped separator waste belt hooked by the hook rod 4 enters the cutting groove 23 corresponding to the mounting block 19, at this time, the cutting assembly 9 in the cutting groove 23 is controlled by the control device to cut the long strip-shaped separator on the hook rod 4, thereby cutting the originally continuous long strip-shaped waste belt into short segments. The short segment separator waste belt after cutting, under the pushing force of the continuously rotating hook rod 4 or the guiding effect of the guide block 20, enters the crushing mechanism 2 from the treatment box 3, and finally enters the crushing mechanism 2 together with other solid waste for crushing. The crushed waste is discharged from the discharge port 25. The overall structure has high automation degree. Through the cooperation of the hook rod 4 and the cutting assembly 9, the continuous long strip-shaped waste belt is cut into short segments in advance, and the short segments will not be wound on the crushing roller due to the length being too long after entering the crushing mechanism 2, thereby ensuring the normal operation of the crushing roller.

[0024] It should be noted that in this embodiment, the structures of the guide block 20 and the mounting block 19 can refer to Figure 5 and Figure 6As shown, the first motor 10 is fixedly installed on the treatment box 3, and the driving shaft of the first motor 10 is fixedly connected with the first rotating shaft 17; the hook rod 4 is fixedly installed on the first rotating shaft 17, and the crushing mechanism 2 is fixedly installed on the base 1, and the discharge port 25 is arranged at the bottom of the crushing mechanism 2.

The barbs 42 are bent towards the first rotating shaft 17, and a plurality of barbs 43 are fixedly installed on the inner side of the barbs 42 along the length direction thereof. Specifically, the rod body 41 of the hook rod 4 is fixed to the first rotating shaft 17, the barbs 42 are bent towards the rotating shaft, and the inner barbs 43 increase the friction force. When the hook rod 4 rotates, the barbs 42 and the barbs 43 are embedded into the surface of the long strip of the membrane, and the membrane is firmly gripped by the centrifugal force and the friction force, preventing it from slipping off. The combination design of the barbs 42 and the barbs 43 enhances the holding force of the flexible membrane, especially for light and thin materials that are easy to slide. During the gripping process, the membrane is evenly spread, reducing the risk of entanglement caused by local stress concentration. It should be noted that the first rotating shaft 17 drives the hook rod 4 to rotate towards the feeding port 14, and the barbs 42 rotate towards the feeding direction, so that the barbs 42 directly contact the long strip of the membrane flowing into the feeding port 14.
