Abstract
The invention discloses a rotary kiln with a barrel applying negative pressure, which comprises the barrel, a kiln head cover, a kiln tail cover and a sealing device, wherein the kiln head cover and the kiln tail cover are respectively connected with two ends of the barrel, the sealing device comprises a first sealing barrel cover and a second sealing barrel cover, and the rotary kiln is characterized in that: the first sealing cylinder cover and the second sealing cylinder cover are respectively arranged at the joint of the cylinder body and the kiln head cover and the joint of the cylinder body and the kiln tail cover; the first sealing cylinder cover and the second sealing cylinder cover comprise T-shaped cavities; the cylinder body penetrates through the T-shaped cavity; the tail part of the T-shaped cavity is arranged with the cylinder body; the front end of the T-shaped cavity is fixed with a kiln head cover or a kiln tail cover; the inner side of the T-shaped cavity is provided with a T-shaped inflatable inner container and a fold ring arranged on the front side of the T-shaped inflatable inner container. According to the rotary kiln, when the cylinder is internally provided with positive pressure, the T-shaped inflatable liner acts on the wrinkle ring, materials are difficult to leak, and when the cylinder is internally provided with negative pressure, the wrinkle ring and the wrinkle layer are sucked, so that air is prevented from entering.
Description
Technical Field
The invention relates to mechanical equipment, in particular to a rotary kiln with a barrel applying negative pressure, and belongs to the technical field of rotary kilns.
Background
The rotary kiln is an important thermal equipment for alumina factories, cement factories and other metallurgical and chemical industries. The rotary kiln comprises a barrel body, a kiln head cover and a kiln tail cover which are respectively fixed at two ends of the barrel body, wherein the kiln head cover or the kiln tail cover inevitably exists between the barrel body
There is a gap. When the rotary kiln is operated under negative pressure, external air with high pressure enters the cylinder of the rotary kiln, so that combustible materials in the kiln are combusted or the quality of products is reduced; when the rotary kiln is operated at positive pressure, the materials in the barrel of the rotary kiln are splashed, and dust is splashed out of the barrel, so that the production safety is directly influenced; the Chinese application number 201310033179.6 discloses a rotary kiln with a barrel body applying negative pressure, which comprises a barrel body, a kiln head cover and a kiln tail cover, wherein the kiln head cover and the kiln tail cover are respectively connected to two ends of the barrel body; the first end of the second sealing cylinder cover is connected to the outer wall of the kiln tail cover through a first connecting structure, the second end of the second sealing cylinder cover is connected to the cylinder through a second connecting structure, one of the first connecting structure and the second connecting structure at the two ends of the second sealing cylinder cover is a fixed connecting structure, and the other one of the first connecting structure and the second connecting structure is a movable sealing structure. The invention solves the problem that the air outside the rotary kiln enters the cylinder of the rotary kiln and the gas in the cylinder of the rotary kiln carries the material to leak; although the technical scheme can solve the problems of material splashing and air entering the rotary kiln, the structure is complex and the cost investment is large.
