Waste lithium battery pyrolyzing furnace

Abstract

The invention discloses a waste lithium battery pyrolyzing furnace, comprising a frame. A pyrolyzing furnace is installed at the top of the frame; a feed sealing box is provided at one end of the pyrolyzing furnace, and is connected with a feed assembly; a material turning plate is rotatably connected to one side of the feed sealing box in the pyrolyzing furnace; the material turning plate is connected with a drive motor fixed to the outer wall of the pyrolyzing furnace; a discharge sealing box is fixed to the other end of the pyrolyzing furnace; the discharge sealing box is connected with a discharge assembly through a discharge port in the bottom; a rotating cylinder is rotatably connected to one side of the discharge sealing box in the pyrolyzing furnace; a tail gas treatment assembly is mounted at the furnace head part of the pyrolyzing furnace; and a plurality of burners are mounted on the pyrolyzing furnace and positioned at the periphery of the rotary cylinder at equal intervals. The waste lithium battery pyrolyzing furnace is novel in structure and ingenious in conception, achieves the purpose of waste heat recycling, can effectively save the consumption of natural gas, andachieves the purposes of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the technical field of lithium battery treatment, in particular to a waste lithium battery pyrolysis furnace. Background technique [0002] Abandoned lithium batteries contain a large amount of non-renewable heavy metal resources with high economic value. The positive electrode material in lithium batteries is lithium cobalt oxide powder, and the negative electrode material is graphite powder. Both positive and negative electrodes contain a large amount of cobalt, Nickel, manganese, copper, aluminum and other metal materials; if discarded or unqualified lithium batteries can be effectively recycled, it will not only reduce the environmental pressure of waste batteries, but also avoid the waste of heavy metal resources such as cobalt, nickel and manganese. Therefore, due to the shortage of resources and the needs of environmental governance, countries all over the world attach great importance to the recycling of waste lithium b...

Problems solved by technology

However, the existing pyrolysis treatment system cannot recycle the waste heat. The loss of a large amount of heat will increase the consumption of natural gas and consume a lot of data.
