Lithium Battery High Temperature Cracking Furnace

The appearance of lithium battery pyrolysis furnace improves the recovery rate of metal resources (nickel, cobalt, lithium, copper, aluminium, etc.). Formed a green lithium battery recycling mode. Lithium battery cracking furnace process. Without discharge treatment, the cracking furnace can effectively recover electrolyte. Let the waste lithium battery reduce the emission of harmful gases in the decomposition process. The whole process adopts high temperature pyrolysis process under oxygen-poor conditions. Cry improve the recovery efficiency of electrolyte and metal recovery rate. So as to achieve the resourcefulness of leaving the shop. High-value conversion and utilisation.


The pyrolysis furnace is equipped with several burners on the four axes of the rotating cylinder. The interior of the pyrolysis furnace can he connected to the heat exchanger through a waste heat recovery pipe. The air inlet is connected to the combustion fan through the air inlet pipe. An air pressure valve is mounted on top of the air inlet pipe. The first outlet gas of the heat exchanger is connected to one side of the burner via a combustion tube. An explosion-proof valve is mounted on the combustion tube. The second outlet of the heat exchanger is fitted with an exhaust pipe. The raw material is stored in a silo. Through the discharge valve into the loading screw device, the material will be fed into the lithium battery pyrolysis furnace inside, natural gas in the pyrolysis furnace inside combustion, produce high temperature flue gas radiation on the pyrolysis furnace inside the rotating cylinder outer indirect heating. The heat is transferred to the raw material inside the rotating cylinder through the outer wall of the rotating cylinder. The material is heated up. The flue gas from the pyrolysis furnace passes through the waste heat recovery tube into the interior of the heat exchanger and the room temperature air from the workshop. Then it is pressurised by the combustion fan. Heat is exchanged with the heat exchanger. The waste heat in the flue gas is recovered. The hot air goes to the pyrolysis furnace as combustion air. Another hot air into the exhaust gas combustion chamber as combustion air, play the purpose of waste heat recycling, can effectively save the use of natural gas. It can save natural gas effectively. The exhaust gas treatment system includes: secondary combustion chamber, cyclone dust collector, temperature sensor, pulse dust collector, spray tower, cooling tower and so on.

Lithium battery high temperature cracking furnace, lithium battery material calcining rotary kiln, black mass high temperature roasting rotary kiln components:

1. The combustion system is mainly composed of burner, proportional adjustment valve, solenoid valve, electric actuator, atomised combustion aid device, ignition device and so on.

2. The cylinder body with sprocket or gear, supported by rollers at both ends, is driven by FM motor through sprocket or gear. The material of the cylinder body can be chosen different materials according to the process requirements. It is equipped with coping board inside.

3、The kiln body is situated on the steel frame, which is mainly made of lightweight heat preservation material masonry. The use of folding blocks, zirconium-containing ceramic cotton blanket, reducing heat storage. The labyrinth seal is made up of refractory material and fire stopping ring of the cylinder body.

4, the driving device can be chain drive and gear drive, reducer has two out of the shaft, can be added to the manual device, in order to shake the cylinder in case of emergency to protect it from damage.

5、Feeding and discharging system, mainly consists of feeding hopper, feeding screw, mixing device, feeding cover and so on.

6、 Electric heating device, according to the thermocouple display temperature and finished product drying, adjust the power of electric heating device, so as to change the drying effect.
