[0026] In the description of the utility model, it needs to be explained that, unless there is explicit provision and limitation, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or it can be detachable connection, or it can be integrally connected, it can be mechanical connection, or it can be electrical connection, it can be directly connected, or it can be indirectly connected through intermediate medium, it can be the communication inside two elements, for ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.
[0027] The technical scheme of the utility model will be described clearly and completely in combination with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary skilled in the art without creative labor belong to the protection scope of the utility model.
[0028] Referring to Figure 1 And Figure 2 The utility model provides a kind of waste lithium battery four-axis oxygenless crushing system, comprising:
[0029] Weighing hoist 1, weighing hoist 1 side is equipped with crusher;
[0030] Transition sealing bin 4 and shredding sealing bin 6 are arranged on the crusher, sealing gate one 3 and sealing gate two 5 are installed on the crusher, four-axis pulverizer 7 is installed on the crusher, and feed hopper 2 is installed on the top of the crusher.
[0031] Specifically, weighing hoist 1 is provided with a lifting hopper, a weighing sensor is arranged on the lifting hopper, an alarm and a controller are arranged on the weighing hoist 1, and the weighing sensor and the alarm are electrically connected with the controller.
[0032] Through the above structure, the weight of the feed can be accurately measured to ensure the sealing crushing feed amount.
[0033] Specifically, transition sealing bin 4 is located between sealing gate one 3 and sealing gate two 5, nitrogen valve one and oxygen content analyzer one are installed on transition sealing bin 4, it needs to be explained that, waste lithium battery is in transition sealing bin 4, nitrogen valve one in transition sealing bin 4 is opened to start spraying nitrogen, when the oxygen content concentration in transition sealing bin 4 decreases to the set value, nitrogen valve one is closed, and sealing gate two 5 is opened.
[0034] Specifically, the nitrogen valve two and the oxygen content analyzer two are installed on the shredding sealed bin 6. It should be noted that if the oxygen content concentration in the shredding sealed bin 6 exceeds the set value during the crushing process, the crusher stops and the nitrogen valve two on the shredding sealed bin 6 is opened. When the oxygen content concentration is lower than the set value, the crusher restarts and the crushing process begins. The full-sealed oxygen-free crushing effectively prevents short circuit and fire during the lithium battery crushing process, and is safer.
[0035] Specifically, a screen is installed at the bottom of the crusher. It should be noted that the size of the discharged material after shredding can be accurately controlled.
[0036] Specifically, a safety explosion venting membrane and a flameless explosion venting valve are installed on the shredding sealed bin 6. It should be noted that when the internal pressure of the shredding sealed bin 6 exceeds the set value, the explosion venting membrane will rupture and rapidly release the internal pressure to prevent the shredding sealed bin 6 from exploding. The flameless explosion venting valve can be quickly opened to release the explosion pressure and prevent the flame and explosion products from spreading outward. The combination of the safety explosion venting membrane and the flameless explosion venting valve provides double safety protection. When the internal pressure of the shredding sealed bin 6 exceeds the set value, the explosion venting membrane ruptures first to release the internal pressure. If the explosion venting membrane fails to completely control the explosion, the flameless explosion venting valve will open under the action of the explosion pressure to further release the pressure and prevent the flame from spreading.
[0037] Working principle:
[0038] 1. The waste lithium battery is put into the lifting hopper on the weighing lifting machine 1. When the weight reaches the set weight, the alarm gives an alarm to stop feeding, the lifting hopper starts to lift and automatically turns over to the upper limit position, and the waste lithium battery in the lifting hopper is poured into the feeding hopper 2 of the crusher;
[0039] 2. The lifting hopper descends to the lower limit position, the sealing gate one 3 is closed, the waste lithium battery is in the transition sealed bin 4, the nitrogen valve one in the transition sealed bin 4 is opened to start spraying nitrogen, and when the oxygen content concentration in the transition sealed bin 4 decreases to the set value, the nitrogen valve one is closed and the sealing gate two 5 is opened;
[0040] 3. When the sealing gate two 5 is closed, it stops for 10 seconds and then the sealing gate two 5 is closed;
[0041] 4. The crusher starts to crush the waste lithium battery, and the four-axis pulverizer 7 on the crusher is used to crush the waste lithium battery. When the size of the material is crushed to the qualified size, it is discharged through the bottom screen. If the oxygen content concentration in the shredding sealed bin 6 exceeds the set value during the crushing process, the crusher stops and the nitrogen valve two on the shredding sealed bin 6 is opened. When the oxygen content concentration is lower than the set value, the crusher restarts and the crushing process begins. The full-sealed oxygen-free crushing effectively prevents short circuit and fire during the lithium battery crushing process, and is safer;
[0042] 5. The combination use of the safety explosion relief membrane and the flameless explosion relief valve can provide double safety protection, when the internal pressure of the shredded sealed bin 6 exceeds the set value, the explosion relief membrane is first broken to release the internal pressure; if the explosion relief membrane fails to completely control the explosion, the flameless explosion relief valve will be opened under the action of the explosion pressure to further release the pressure and prevent the flame from spreading.
[0043] The above has carried out the detailed introduction to the four-axis oxygen-free crushing system of the waste lithium battery provided by the utility model. The principle and implementation mode of the utility model are described in the text by applying specific examples, and the above example is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary skilled personnel in the technical field, on the premise of not departing from the principle of the utility model, the utility model can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the utility model claims.
