      With the gradual rise of waste lithium battery recycling machinery  in the utilization, it is required that the waste lithium battery recycling treatment technology and devices should also be further improved. Because according to the latest market data, from January to November 2021, the production and sales of new energy vehicles completed 3.023 million and 2.99 million respectively, both up 1.7 times year-on-year; the market penetration rate reached 12.7%. Among them, the market penetration rate of new energy vehicles has reached 17.8% in November, and the penetration rate of the new energy passenger car market even reached 19.5%. It only took 11 months for the production of new energy vehicles to come to the level of 3 million units, which is much higher than expected. It is widely predicted that in 2022, the sales of new energy vehicles are expected to exceed 6 million units. From 1.3 million units to 3 million units, and then to the expected 6 million units, new energy vehicles are really ushering in the "first year of the explosion".


     Scrap lithium battery recycling machinery and retired lithium battery recycling device technology has been further improved, from the previous separate physical crushing of used lithium batteries to the current combination of fire method, a single line can be disposed of 50,000 tons per year. The charged lithium battery into the oxygen-poor crushing system, the crushed charged lithium battery materials directly into the oxygen-free cracking system under the protection of inert gas, the charged lithium battery heated in the cracking system to discharge heat to make the secondary use of charged electrical energy, while the electrolyte, plastic film, plastic and adhesives and other organic materials for their own cracking, cracking gas generated by the purification of the cracking system for heating, cracking materials after cooling, magnetic separation, After wind selection, iron, nickel, aluminum block, copper block, stainless steel are sorted out, and then the sorted out cracked pole piece is screened and graded by friction de-powdering to separate the pole powder and metal particles, and the metal particles are then graded by specific gravity sorting for copper and aluminum separation. Production in a variety of waste gas cracking gas and vacuum by the integrated combustion system combustion heating, combustion exhaust gas after cooling spray, water vapor separation and adsorption for standard emissions.

 

Scrap lithium battery recycling processing machinery and equipment (fire method) advantages: 


      1. Inert gas protection crushing to ensure production stability, safety and environmental protection, and charged in the cracking of the discharge heat to achieve the re-use of electricity, reduce the discharge input and production costs.

      2 lithium charged recovery requires a smaller amount of inert gas, reducing production costs and production difficulties, the same amount produces waste gas treatment and wastewater volume is reduced, cracking gas purification to furnace heating. Combustion exhaust gas by simple spraying treatment to meet the standard emissions.

      3 charged recovery production process is simpler, the production line equipment investment is smaller, resulting in a small footprint, the pole piece of cracking after the pole powder and aluminum and copper recovery rate is higher and the output is large, the annual processing capacity of a single production line up to about 45,000 tons;

      4. Inhibit dioxin and harmful gas generation due to oxygen-free cracking. Less investment in waste gas treatment, low treatment cost, no need for heat storage and combustion equipment.

      5. The material is not separated out from the heavy metal before cracking, and there is no odor generated from the heavy material separated out by cracking.

      6. Lithium hexafluorophosphate (LIPF6) produces hydrogen fluoride by volatile pyrolysis, and anhydrous hydrogen fluoride reacts with FE, AL, NI, MG and other metals to form a protective film of fluoride insoluble in hydrogen fluoride, so solid and gaseous hydrogen fluoride is not corrosive. Cracking flammable gas is purified to heat the furnace. Combustion exhaust gas is treated to meet the standard emission to reduce

 

      Waste lithium battery recycling equipment Waste lithium battery recycling device as follows


      Waste lithium battery recycling machinery and equipment Waste lithium battery recycling device consists of feeding system, poor oxygen crushing and breaking system, electrolyte thermal volatile poor oxygen system, sorting system, diaphragm dry cleaning system, high speed friction sorting, closed screening system, specific gravity sorting system, thermal volatile system of electrolyte, tail gas waste heat recycling system again, waste gas treatment and purification system. The use of adjustable quantitative feeding, without manual labor, makes the feeding uniform; the sealed conveying belt is designed as a small square grid to ensure that only a small number of square-cased cells enter each time, ensuring that the cells are not discharged during the conveying process. And the feeding volume is adjusted by the rotational speed of the belt with metering device. Negative pressure suction is carried out at the top end of the fully enclosed belt to prevent odor emission from broken batteries.
