Vertical vibration conveying continuous sintering kiln

Abstract

The invention discloses a vertical vibration conveying continuous sintering kiln. The vertical vibration conveying continuous sintering kiln comprises a kiln body, a feed pipe, a discharge pipe, a conveying device and a heating device. The conveying device comprises a stand column, a conveying plate, a vibrator and a base assembly. The base assembly is located at the bottom of the kiln body. The stand column is perpendicularly erected in the kiln body and mounted on the base assembly. The conveying plate is wound around the stand column upward spirally to form a spiral conveying channel. The vibrator is used for driving the stand column and the conveying plate to vibrate to make powder move upwards along the spiral conveying channel. The feed pipe communicates with the bottom end of the spiral conveying channel. The discharge pipe communicates with the top end of the spiral conveying channel. The heading device is used for heating the powder in the kiln body. According to the vertical vibration conveying continuous sintering kiln, the motion state and the motion manner of the powder are changed, the reactivity of the power during sintering is greatly improved, products are high in reactivity and good in uniformity, the occupied space and energy consumption are reduced, and continuous production is realized. The vertical vibration conveying continuous sintering kiln not only has high-temperature uniformity and sealing performance of small kilns but also has high production efficiency of large kilns.

Description

technical field [0001] The invention relates to the technical field of powder sintering, in particular to a vertical vibration conveying continuous sintering kiln. Background technique [0002] Energy issues have always been a major issue in the development of human society and science and technology. As a green secondary battery with high energy density, lithium-ion batteries have been widely used in consumer electronics such as notebook computers, mobile phones, and cameras. Lithium ion battery cathode active material or negative electrode active material is an important part of lithium ion battery, powder sintering is currently a common method for preparing lithium ion battery cathode active material or negative electrode active material. [0003] There are two main types of powder sintering kilns (mainly referring to the sintering of ferrite, lithium battery cathode materials, vanadium-iron additives, etc.), continuous sintering kiln and discontinuous sintering kiln.

AI Technical Summary

Problems solved by technology

[0004] (1) Because of its continuous sintering function, it needs some auxiliary equipment, such as propulsion mechanism, atmosphere protection gate, automatic feeding device, automatic unloading device, etc., so the equipment is often bulky, occupies a large area, and consumes a lot of power;

[0005] (2) A large number of devices and components have high requirements for automation design and control, and the failure rate is high;

[0006] (3) High cost and high maintenance cost; high power consumption and high use cost

[0008] (1) Only one batch (tray) of products can be sintered at a time, the production is discontinuous, the output is small, the production efficiency is relatively low, and the consistency of the products is difficult to guarantee;

[0009] (2) Its structure determines that each sintering requires manual feeding, and the labor intensity of workers is high;

[0010] (3) Every time the product is fired and the furnace is turned on, a lot of energy will be wasted and heat radiation will be caused to the environment
