[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0029] A waste lithium battery rapid discharge system, such as Figure 1-3 As shown, it includes: a feed mechanism 1, a material distribution mechanism 2, a needle discharge mechanism 3, a water cooling mechanism 4 and a draining mechanism 5 connected in sequence, and the needle discharge mechanism 3 and the water cooling mechanism 4 are also connected to an exhaust gas treatment mechanism 6; a first height limiting device 7 for adjusting the feed thickness and angle is provided at the feed port of the feed mechanism 1. The feed mechanism 1 includes a conveyor belt (or conveyor belt) and a feed port. The first height limiting device 7 is arranged in the feed port of the feed mechanism 1. When the waste lithium battery enters, it is limited by the first height limiting device 7 so that it can only enter the conveyor belt or conveyor belt of the feed mechanism 1 along the wall of the feed port at a certain angle.

[0030] In some specific embodiments, Figure 3As shown, the first height limiting device 7 is composed of an adjusting rod 71, a fixing rod 72 and a baffle 73; the fixing rod 72 is fixedly arranged on the wall of the feed port and vertically connected to the adjusting rod 71, one end of the adjusting rod 71 is connected to the baffle 73, the lower surface of the baffle 73 is parallel to the upper surface of the conveyor belt or the conveyor belt, and the baffle 73 moves up and down under the action of the adjusting rod 71, thereby adjusting the feed thickness. When the waste lithium battery enters the conveyor belt at a certain angle, it is ensured that it can pass through the baffle 73 along the conveying direction of the conveyor belt, so that the thickness of the waste battery entering the material distribution mechanism 2 is uniform.

[0031] In some specific embodiments, Figure 4 As shown, adjustment mechanisms 21 are respectively provided on both sides of the cloth mechanism 2, and multiple sets of second height limiting devices 8 with adjustable heights are provided between the adjustment mechanisms 21. The second height limiting devices 8 include height limiting rods 81, and the height limiting rods 81 are arranged between the two adjustment mechanisms 21. The adjustment mechanisms 21 are arranged on both sides of the conveyor belt of the cloth mechanism 2.

[0032] In some specific embodiments, two height limiting rods 81 are provided between the adjustment mechanisms 21 , and a height limiting plate is provided between the two height limiting rods 81 .

[0033] In some specific embodiments, Figure 5 As shown, the adjustment mechanism 21 is provided with a U-shaped groove 22, and the height limiting rod 81 passes through the U-shaped groove and moves along the U-shaped groove 22 to adjust the height. The position of the height limiting rod 81 in the U-shaped groove 22 is adjusted, and then the height of the height limiting rod 81 and the surface of the material distributing mechanism 2 is adjusted, so as to adjust the feeding thickness entering the acupuncture mechanism 3.

[0034] In some specific embodiments, Figure 5 As shown, the adjusting mechanism 21 is also provided with a driving motor 23 for adjusting the height of the adjusting mechanism 21 , which, combined with the design of the U-shaped groove 22 , jointly adjusts the height of the second height limiting device 8 from the surface of the material distributing mechanism 2 .

[0035] In some specific embodiments, Figure 6 As shown, bolts 82 are respectively provided at both ends of the adjusting rod 81 , and the second height limiting device 8 is fixed to the material distributing mechanism 2 and the position of the height limiting rod 81 in the U-shaped groove 22 is fixed by the bolts 82 .

[0036] In some specific embodiments, the water cooling mechanism 4 includes a conveyor belt and a spray mechanism. The spray mechanism is arranged above the conveyor belt, and mesh holes are arranged on the conveyor belt.

[0037] In some specific embodiments, the water cooling mechanism 4 further includes a motor, which is electrically connected to the conveyor belt and is used to control the rotation speed of the conveyor belt.

[0038] In some specific embodiments, the water cooling mechanism 4 includes a multi-layer conveyor belt and a multi-layer spray mechanism. The multi-layer conveyor belt is arranged in a zigzag structure to fully utilize the spray water washing to improve the cooling efficiency.

[0039] In some specific embodiments, the water cooling mechanism 4 also includes a water circulation device. A spray mechanism may be provided above each conveyor belt, and the spray water is filtered and purified in the water circulation device to achieve circulation, thereby saving the amount of spray water and reducing the amount of waste water discharged.

[0040] In some specific embodiments, the acupuncture discharge mechanism 3 is composed of a fixed roller and a movable roller, wherein the movable roller is provided with a pricking needle. The movable roller is arranged on an adjustable bracket, and height adjustment devices are provided at both ends of the bracket. The movable roller is moved up and down by adjusting the adjustment devices at both ends of the bracket, thereby adjusting the distance between the movable roller and the fixed roller, which solves the requirement of the gap for batteries of different thicknesses to pass through while ensuring the acupuncture depth, and prevents the problem of equipment jamming due to insufficient gap. After the thickness of the waste battery is adjusted by the cloth mechanism 2, it enters the gap between the fixed roller and the movable roller in the acupuncture discharge mechanism 3, and the pricking needle discharges the waste battery. The acupuncture discharge mechanism 3 in the present application can also be a structure with acupuncture discharge function in other prior arts.

[0041] In some specific embodiments, Figure 1 As shown, it also includes an integrated control mechanism 9, which is electrically connected to the feeding mechanism 1, the material distribution mechanism 2, the needle puncture discharge mechanism 3, the water cooling mechanism 4 and the draining mechanism 5. The integrated control mechanism 9 sets the conveying rate of the feeding mechanism 1 and the material distribution mechanism 2 according to the type of the waste battery, adjusts the height of the first height limiting device 7 and the second height limiting device 8, and realizes the controllable feeding thickness; and adjusts the gap width between the moving roller and the fixed roller (that is, adjusts the needle puncture depth). After the waste battery passes through the needle puncture discharge mechanism 3, it enters the water cooling mechanism 4, and the waste gas enters the exhaust gas treatment mechanism 6 for treatment and discharge. The waste battery is quickly cooled by spraying water in the water cooling mechanism 4 and transferred to the draining mechanism 6 for draining or air drying.

[0042] In some specific embodiments, the integrated control mechanism 9 adopts a modular design, and through the hierarchical control of each mechanism, the adjustment and matching of each mechanism can be carried out quickly, which greatly improves the degree of system automation and reduces the input of manpower. For example, the integrated control mechanism 9 is provided with an anti-stuck interlocking program. When the discharge system is stuck, the feeding mechanism 1 will automatically stop, and the speed of the material distribution mechanism 2 will be slowed down; the integrated control mechanism 9 is provided with a shutdown interlocking program. When the temperature in the water cooling mechanism 4 is too high, the feeding mechanism 1 and the material distribution mechanism 2 will automatically stop, and the speed of the conveyor belt in the water cooling mechanism 4 will automatically slow down.
