Abstract

The invention discloses a rotary kiln with functions of reducing waste heat volatilization efficiency and recycling waste heat. The rotary kiln is used for firing lithium battery raw materials. The rotary kiln comprises a rotary drum body, the rotary drum body comprises a drum body and two supporting annular sleeves, and the two ends of the drum body are movably connected with the supporting annular sleeves in a sleeved mode respectively and supported by the supporting annular sleeves so that the drum body can rotate relative to the supporting annular sleeves. A driven gear is fixed to the outer wall of the drum body, and the driven gear is used for being connected with an external driving gear to drive the drum body. A raw material firing cavity and a gas heat insulation cavity which are mutually independent are arranged in the rotary drum body. The raw material firing cavity extends in the axial direction of the rotary drum body. The gas heat insulation cavity is of an annular structure and surrounds the periphery of the raw material firing cavity, and the gas heat insulation cavity also extends in the axial direction of the drum body. The gas heat insulation cavity is provided with a gas inlet which communicates with a gas source, and the gas heat insulation cavity communicates with the raw material firing cavity through a gas outlet of the gas heat insulation cavity. The volatilization efficiency of waste heat can be reduced; and the waste heat can be fully recycled and utilized, so that the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of rotary kilns, in particular to a rotary kiln with functions of reducing waste heat volatilization efficiency and recovering waste heat. Background technique [0002] Rotary kiln refers to rotary calcining kiln, commonly known as rotary kiln, which is used in many fields. According to different processing materials, there are cement kilns, metallurgical and chemical kilns, lime kilns, ceramsite kilns and lithium battery kilns. Among them, according to the different materials, the process varies widely. In particular, the required environment is also different. [0003] At present, there are many heating methods for rotary kilns used to burn lithium battery raw materials, such as galvanic heating, natural gas heating, coal mine heating, etc. Obviously, the heating methods for rotary kilns range from coal mine heating to natural gas heating to electric heating. Even heating, gradually saving energy consum...
