Sealing device for rotary kiln

Abstract

The invention relates to the field of rotary kilns and particularly relates to a novel sealing device for a rotary kiln, which is suitable for sealing gas flow and dust for various rotary kilns. The sealing device sleeves a rotary kiln barrel body; a sealing structure is formed between a massage block and the rotary kiln barrel body; one end of the sealing device is connected with a kiln head cover or a kiln tail cover through a connecting plate; the sealing device comprises a connecting plate, a fixing plate, a front wedge block, a rear wedge block, a slide wheel frame, a slide wheel, a steel wire rope, a counter weight and a friction block. The sealing device has the characteristics of a good sealing effect, a reliable structure, convenience in maintenance, and capacity of preventing material leakage, protecting the environment and saving the energy resources, and can be used for solving problems that the sealing for the kiln head and the kiln tail is invalid as axial displacement and radial jumping are produced in the barrel body in the prior ar.

Description

technical field [0001] The invention relates to the field of rotary kilns, in particular to a novel sealing device for rotary kilns, which is suitable for sealing airflow and dust of various rotary kilns. Background technique [0002] In the production of alumina, cement and carbon, the rotary kiln is an important equipment, and the seal of the kiln head and kiln tail is an important structural component. The previously used kiln head and kiln tail seals have relatively large defects. During the operation of the rotary kiln, the impact of the cylinder body will cause axial displacement and radial runout, which will affect the sealing of the kiln head and kiln tail seals. The effect, especially the large radial runout of the cylinder, sometimes causes the seal failure of the kiln head and kiln tail. Once the sealing effect of the kiln head and kiln tail is not good, a large amount of materials and heat in the kiln will flow into the atmosphere, resulting in waste of heat, po...
