Abstract

The invention discloses a differential kiln capable of automatically cooling a bearing to realize dust removal. The differential kiln comprises a kiln body, a loop tower, a loop tower bearing and a high-pressure blower communicated with the kiln body, wherein the loop tower bearing comprises balls, a lower ball seat fixedly arranged and an annular upper ball seat arranged on the lower ball seat; a ball groove is arranged between the upper ball seat and the lower ball seat; the upper ball seat or lower ball seat is provided with an air inlet communicated with the ball groove; the air inlet is communicated with the high-pressure blower; and the upper ball seat is provided with an air outlet communicating the ball groove and the upper surface of the upper ball seat. In use, high-pressure air generated by the high-pressure blower is blown into the ball groove through the air inlet and then discharged into the kiln for calcining through air outlet, and the process can effectively cool the balls and the ball groove and remove dust out of the ball groove; and meanwhile, a certain air pressure is kept in the ball groove, thereby effectively preventing external dust from moving in the ball groove. Thus, in a working environment of a low rotation speed, the bearing can not seriously damaged without use of any lubricating oil, thereby ensuring that the bearing is maintenance-free.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a shaft kiln for calcining cement. Background technique [0002] At present, there are two main types of cement kilns, one is the rotary kiln with the kiln body placed horizontally and capable of rotary motion; , Low energy consumption and other advantages. [0003] When the shaft kiln produces cement, the cement clinker will be deposited at the bottom of the shaft kiln. For normal discharge, a clinker crushing device needs to be installed at the bottom of the shaft kiln. A plane bearing is installed under the ring tower of the shaft kiln. The working environment is a high temperature and dusty environment. The existing oil-lubricated bearings are easily damaged by the high temperature and dusty environment, and have a short service life. Once damaged, it is very difficult to maintain, which greatly affects the efficiency of cement production. [0004] In view of the ...
