Abstract
The utility model relates to an end cooling air duct of a rotary kiln, which is composed of an air duct outer wall, a cylinder wall, a bayonet iron and a partition board. The utility model is characterized in that a channel (6) is arranged between the partition board and the bayonet iron. With the utility model, when the cooling air enters one air duct, the cooling air can flow to the right and the left adjacent air ducts along the circumferential direction of the cylinder wall to form direction flow so as to improve cooling effect.
Description
Technical field
The utility model relates to a kind of rotary kiln end cooling air channel.
Background technology
Rotary kiln end cooling air channel is an annular space, will be divided into each independently air channel a week with dividing plate radially, mutually UNICOM not.Air channel with the cylindrical shell rotation, accept fixed limited several tuyere air-supplies in turn, when a certain air channel faced toward tuyere, cooling air did not have fixing loop in this air channel, formed turbulent flow, cooling effect is bad, barrel, dividing plate, the easy oxidation of air channel outer wall, and barrel dilatancy at high temperature, cracking easily, the refractory material of barrel liner comes off, and causes cylindrical shell short service life.
Summary of the invention
The purpose of this utility model is that the rotary kiln end cooling air channel of UNICOM mutually will be provided between a kind of air channel that makes separation.
The technical solution of the utility model is: by the air channel that air channel outer wall, barrel, bayonet socket iron, dividing plate are formed, reserve a passage between dividing plate and bayonet socket iron.
When using the utility model, cooling air to enter a certain air channel, can circumferentially form directed flow toward adjacent air channel, the left and right sides along barrel, improve cooling effect through passage.
Description of drawings
Fig. 1 is the utility model front view.
Among the figure 1, air channel outer wall 2, tuyere, 3, barrel, 4, dividing plate, 5, bayonet socket iron, 6, passage.
The specific embodiment
Introduce the utility model below in conjunction with accompanying drawing.
With reference to accompanying drawing, the annular passage by air channel outer wall 1, barrel 3 are formed along the circumferential direction has plurality of partitions 4, and the end has bayonet socket iron 5 to bind.Reserve a passage 6 between dividing plate 4 in the air channel and the bayonet socket iron 5, in the air channel, blow into the cold wind cooling by tuyere 2.
Claims (1)
1, a kind of rotary kiln end cooling air channel is made up of air channel outer wall, barrel, bayonet socket iron, dividing plate, it is characterized in that: reserve a passage (6) between dividing plate and bayonet socket iron.
