Lithium battery recycling and crushing protection device generating protective gas through reaction

Abstract

The invention relates to the technical field of lithium battery recovery, and discloses a lithium battery recycling and crushing protection device generating a protective gas through the reaction. The device comprises a top cover, a hydrochloric acid storage tank is fixedly connected in the top cover, the outlet end of the hydrochloric acid storage tank is fixedly connected with a connecting pipe, and the bottom of the top cover is fixedly connected with a detection box. The interior of the detection box is fixedly connected with a support frame, and one end of the support frame is fixedly connected with a hydrochloric acid inlet pipe. Diluted hydrochloric acid in the hydrochloric acid storage tank is pumped into a reaction chamber by a suction pump through the connecting pipe and the hydrochloric acid inlet pipe, so that calcium carbonate in the reaction chamber reacts with the diluted hydrochloric acid, a large amount of the carbon dioxide gas and liquid water are generated instantly, the generated liquid water absorbs heat in the box and cools the environment in the box, and meanwhile, the generated carbon dioxide gas is an inert gas. Good flame retardance is achieved, so that the environment in the box is protected by the carbon dioxide gas, and the hazard of fire in the box is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of lithium battery recycling, in particular to a lithium battery recycling broken protection device that utilizes reaction to generate protective gas. Background technique [0002] Lithium batteries are widely used in daily life due to their advantages of high energy density, large working voltage, no memory effect and long cycle life, such as cameras, mobile phones, notebook computers and portable measuring instruments and other electronic products. The preferred light and high-energy power source for electric vehicles. However, after lithium batteries are scrapped, they often bring certain harm to the environment and human health, and cause waste of resources; the recycling and harmless recycling of waste lithium batteries is imminent. At present, in the recycling process of lithium batteries, lithium Battery crushing is the most important step. [0003] In the prior art, it is usually necessary to disch...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a lithium battery recycling and crushing protection device that uses reaction to generate protective gas, which has the characteristics of generating carbon dioxide gas and water by the reaction of calcium carbonate and dilute hydrochloric acid, and uses the generated water to carry out crushing in the crushing chamber. Cool down, use the generated carbon dioxide gas to block combustible gas, and avoid fire and explosion. Problems prone to fire or even explosion hazards
