Embodiment Construction

[0028] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element, or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may be present. "Vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in t...

Abstract

The invention discloses a rotary kiln with functions of reducing waste heat volatilization efficiency and recovering waste heat, which is used for firing lithium battery raw materials. It includes a rotary cylinder, the rotary cylinder includes a cylinder body and two support ring sleeves, and the two ends of the cylinder body are respectively movably socketed on one of the support ring sleeves, and are supported by the support ring sleeves, so that the cylinder body can be rotated relative to the support ring sleeves. Make a turn. A driven gear is fixed on the outer wall of the cylinder, and the driven gear is used to connect with an external driving gear to drive the cylinder. The rotary cylinder is provided with independent raw material firing chamber and gas heat insulation chamber. The raw material firing chamber extends along the axial direction of the rotary cylinder. The gas heat-insulation chamber is in the form of a ring structure and is arranged around the periphery of the raw material firing chamber, and the gas heat-insulation chamber also extends along the axial direction of the cylinder body. The gas heat insulation chamber has an air inlet connected with the gas source, and the gas heat insulation chamber communicates with the raw material firing chamber through its own gas outlet. It can reduce the volatilization efficiency of waste heat; and can fully recover and utilize waste heat, thereby reducing energy consumption.

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...
