A roller kiln sealing transmission device

Abstract

The invention discloses a transmission device for sealing of a roller kiln. The transmission device comprises a plurality of rollers, one end of each roller is mounted on one side wall of the roller kiln through a bearing, and the other end of each roller penetrates the other side wall of the roller kiln and is connected with a power output shaft; one end, with the bearing, of the roller is sealed by a driven-side sealing cover mounted on one side wall of the roller kiln, and the other end of the roller is sealed by a driving-side sealing cover mounted on the other side wall of the roller kiln; the power output shaft is sealed by a main transmission case, and a shaft sealing structure is arranged between an input shaft of the main transmission case and the main transmission case. The transmission device has the advantages that a roller driving portion is enabled to be well hermitically isolated from an external power source, sealing performance of the roller kiln is improved greatly, technological requirements on sintering of lithium battery anode materials are met, and yield and quality of the lithium battery anode materials are improved.

Description

technical field [0001] The invention relates to a roller kiln sealing transmission device, which is especially suitable for a roller kiln developed for sintering positive electrode materials of lithium batteries. Background technique [0002] With the increasingly prominent energy and environmental issues and the need for the development of clean energy technology, lithium batteries have received high attention due to their remarkable advantages and wide applicability. Cathode materials are an important part of lithium-ion batteries, and their performance will be very high. It greatly affects the performance of lithium batteries. The sintering of positive electrode materials is mainly completed by a fully sealed pusher kiln. However, the output of positive electrode materials sintered by pusher kiln is small, the product consistency is poor, the energy consumption per unit output is high, and the maintenance of pusher kiln is cumbersome and takes a long time. .

Problems solved by technology

[0002] With the increasingly prominent energy and environmental issues and the need for the development of clean energy technology, lithium batteries have received high attention due to their remarkable advantages and wide applicability. Cathode materials are an important part of lithium-ion batteries, and their performance will be very high. It greatly affects the performance of lithium batteries. The sintering of positive electrode materials is mainly completed by a fully sealed pusher kiln. However, the output of positive electrode materials sintered by pusher kiln is small, the product consistency is poor, the energy consumption per unit output is high, and the maintenance of pusher kiln is cumbersome and takes a long time.

[0003] Roller kiln sintering cathode materials can improve the above problems very well, but due to the poor sealing effect of roller kiln, it cannot meet the sintering process requirements of cathode materials, and the sealing of the roller rod transmission structure is the fundamental problem affecting the poor sealing performance of roller kiln

[0004] Chinese patent CN200920180946.5 discloses a shaft head sealing device in the non-insulation area of ​​the flat glass annealing kiln roller table. This sealing device is only suitable for sealing in the non-insulation area and cannot be applied to the sintering field of battery positive electrode materials.

Therefore, it is still not really possible to sinter positive electrode materials with roller kilns.
