Embodiment approach

[0046] Such as figure 2 As shown, according to an embodiment of the present invention, the rotary furnace tube of the present invention includes: a furnace chamber 111 , an outer shell 112 , and a filling layer 113 between the furnace chamber 111 and the outer shell 112 . In this embodiment, the shell 112 is also a hollow cylindrical body, and is sheathed on the outside of the furnace 111. The outer diameter of the shell 112 is larger than the outer diameter of the furnace 111, so a ring is formed between the shell 112 and the furnace 111. shaped accommodating space, the filling layer 113 is located in the accommodating space between the shell 112 and the furnace 111.

[0047] Such as figure 2 As shown, according to an embodiment of the present invention, the filling layer 113 includes a first filling portion 1131 and a second filling portion 1132 at opposite ends of the first filling portion 1131 . In this embodiment, the expansion coefficient of the second filling part 1...

Abstract

The invention relates to a boiler furnace, a furnace pipe of a rotary furnace, a rotary furnace and a rotary kiln. The boiler furnace comprises a hollow cylindrical cannular body (1111) and a continuous spiral protrusion (1112) which is arranged on the inner wall of the cannular body (1111) and is integrally formed with the cannular body (1111). The continuous and spiral protrusion is integrally pressed in the boiler furnace, in the process that the furnace pipe of the rotary furnace is used for sintering a high-nickel ternary anode material, the protrusion rotates along with the rotation of the boiler furnace, due to the action of the protrusion, functions of stirring and pushing the material are achieved, the effect that the material is heated evenly in the sintering reaction process canbe achieved, the material makes sufficient contact with oxygen, and the product quality is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of material forming and manufacturing, and in particular relates to a furnace chamber, a rotary furnace tube, a rotary cylinder and a rotary kiln. Background technique [0002] New materials and new energy technologies are changing with each passing day. With the rapid development of lithium batteries, various vehicles and various green energy storage stations are rapidly adopting lithium batteries. Among them, the positive electrode materials in lithium batteries are extremely important and have a wide variety. Recently, a high-nickel ternary cathode material has quickly entered the market because of its high energy density, low self-discharge rate, and excellent cycle life. The prior art is that these materials are formulated, mixed and put into a kind of ceramic "saggar" (commonly used specifications are 320*320*120) and sent to some kind of kiln for high-temperature reaction sintering. The most widely used kilns ...
