A Lithium battery recycling broken protection device using reaction to generate protective gas

Abstract

The present invention relates to the technical field of lithium battery recycling, and discloses a lithium battery recovery crushing protection device that uses reaction to generate protective gas, including a top cover, and a hydrochloric acid storage tank is fixedly connected to the inside of the top cover, and the hydrochloric acid storage tank The outlet end is fixedly connected with a connecting pipe, the bottom of the top cover is fixedly connected with a detection box, the inside 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; The dilute hydrochloric acid is sucked into the reaction chamber by the suction pump through the connecting pipe and the hydrochloric acid inlet pipe, so that the calcium carbonate in the reaction chamber reacts with the dilute hydrochloric acid, and a large amount of carbon dioxide gas and liquid water are generated instantly, so that the generated liquid water absorbs the heat in the tank and is The environment in the box is cooled, and at the same time, the carbon dioxide gas produced is an inert gas, which has good flame retardancy, so that the carbon dioxide gas can protect the environment in the box, thereby effectively avoiding the danger of fire in the box.

Description

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

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
