Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] figure 1 A specific embodiment of the rotary kiln tail sealing structure of the present invention is shown. Such as figure 1 As shown, the rotary kiln tail sealing structure of the present invention includes a kiln 1 and a smoke exhaust channel 7 arranged at the tail of the rotary kiln, and a stationary flange 4 is fixedly arranged between the kiln 1 and the smoke exhaust channel 7 . The stationary flange 4 is fixed between the kiln 1 and the smoke exhaust channel 7 through the base. Such as figure 1 As shown, a gasket 3 is provided between the kiln tail of the kiln 1 and the stationary flange 4, and the gasket 3 is made of rubber material. In order to facilitate the connection, the first fixed flange 2 is fixed at the kiln tail of the kiln 1, and the gasket 3 is fixed on the stationary flange 4. Since the kiln 1 is rotatin...

Abstract

The invention discloses a rotary kiln tail sealing structure. The rotary kiln tail sealing structure comprises a rotary kiln and a smoke discharging channel which is formed in the tail of the rotary kiln tail, wherein a static flange is fixed between the rotary kiln and the smoke discharging channel; a sealing gasket is arranged between the rotary kiln and the static flange; a connection cloth made of high-temperature heat-resistant flexible material is arranged between the static flange and the smoke discharging channel. According to the rotary kiln tail sealing structure, the static flange is arranged between a kiln furnace and the smoke discharging channel and is used for sealing, so that the problem that the rotary kiln tail is poorly sealed with an air discharging channel is effectively solved, and thus the energy is effectively used, the consumption amount of the coal is reduced and the production cost is effectively saved.

Description

technical field [0001] The invention relates to a rotary kiln tail sealing structure. Background technique [0002] In the current new dry process cement process, the impact of system air leakage on the process has attracted more and more attention from cement practitioners. The currently used rotary kiln mainly has the phenomenon of air leakage at the kiln tail, which is caused by the poor sealing of the exhaust channel of the kiln operation part. The air leakage at the kiln tail will directly affect the air volume in the kiln, and even cause insufficient coal combustion, increase coal consumption, and increase the CO content at the kiln tail, which will also cause crust formation in the ascending flue, so it is very important to prevent air leakage at the kiln tail. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotary kiln tail sealing structure with good sealing performance, so as to solve the proble...
