Description

Rotary kiln for lithium battery processing Technical Field The utility model relates to a rotary kiln, in particular to a rotary kiln for lithium battery processing, and belongs to the technical field of lithium battery processing equipment. Background The lithium battery is a battery using a nonaqueous electrolyte solution and using lithium metal or lithium alloy as a positive/negative electrode material, wherein main materials of the lithium battery, such as lithium iron phosphate, lithium cobaltate, lithium manganate and the like, need to be subjected to high-temperature treatment through a rotary kiln. In the prior art, like a rotary kiln for processing lithium batteries in China patent CN2018216585112, a water cooling device is arranged in the kiln body, so that the internal environment of the kiln body which generates heat can be rapidly cooled, the combustion or bursting in the processing process is prevented, the processing of the lithium batteries is facilitated, and the water pipe of the water cooling device is arranged along the axial direction of the kiln body, the water pipe is bent into a wavy shape, the contact area between the water pipe and the internal environment of the kiln body is increased, namely the heat exchange area of the water pipe is increased, the heat dissipation speed of the kiln body can be further increased, and the processing of the lithium batteries is more stable. However, the rotary kiln cannot rotate the kiln body, so that lithium battery powder cannot be sufficiently heated, and the heating is uneven, thereby affecting the heating efficiency. Disclosure of utility model The utility model mainly aims to solve the problems of insufficient heating and uneven heating, and provides a rotary kiln for processing lithium batteries. The aim of the utility model can be achieved by adopting the following technical scheme: The utility model provides a rotary kiln is used in lithium cell processing, includes two assembly plates and installs heating kiln between the two assembly plates, the heating kiln includes the kiln body and installs hot plate on the kiln body outer wall, the front seal board is installed to the one end of the kiln body, the rear seal board is installed to the other end of the kiln body, one side of rear seal board is provided with second driving motor, second driving motor's output is connected with the (mixing) shaft, play bin door has been seted up to the lower part of the kiln body, the screw plate is installed to the inner wall of the kiln body, the outside of the kiln body is provided with first driving motor.
