Description
Technical Field
The utility model relates to a cement manufacture equipment technical field specifically is labyrinth kiln head coal injection pipe sealing device.
Background
In the production process, the kiln head coal injection pipe needs to continuously move back and forth along with the change of the calcination condition in the kiln, and generally, the back and forth movement distance of the coal injection pipe is about 600 to 800 millimeters under the normal calcination condition, so that a gap between the coal injection pipe and a kiln door spray hole becomes an air leakage point. Because the rotary kiln is generally used for maintaining negative pressure calcination, cold air is introduced from the position while the rotary kiln is still hot, unnecessary heat loss is caused, and the reason for increasing the coal consumption is also caused.
SUMMERY OF THE UTILITY MODEL
The technique that exists is not enough to the aforesaid, the utility model aims at providing labyrinth kiln head coal injection pipe sealing device, through adding between coal injection pipe and kiln door orifice and establishing labyrinth sealing device, realize sealed lock wind, reduce the extravagant purpose of the energy.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a labyrinth type kiln head coal injection pipe sealing device, which comprises a fixed cover, a telescopic pipe and a sealed flange plate, wherein the fixed cover is fixed at a kiln door spraying hole, and one end of the telescopic pipe is fixedly connected with a coal injection pipe through the sealed flange plate; fixed cover establishes inside and outside two pipe together, two including the cover the pipe is close to one end body coupling of kiln gate orifice, flexible pipe cover is established interior bobbin outer wall with in the first clearance that outer bobbin inner wall formed, flexible pipe's inner wall with the outer wall of interior pipe forms the second clearance, flexible pipe's outer wall with the inner wall of outer pipe forms the third clearance, the second clearance and all pack in the third clearance has the rock wool.
Preferably, one end of the outer circular tube, which is close to the kiln door spray hole, extends outwards along the circumferential direction to form an annular fixing plate, one end of the outer circular tube, which is far away from the kiln door spray hole, extends outwards along the circumferential direction to form an annular reinforcing plate, the fixing cover is fixed at the kiln door spray hole through an expansion bolt which is arranged on the annular fixing plate in a penetrating mode, and the inner diameter of the fixing cover is larger than the diameter of the kiln door spray hole.
The beneficial effects of the utility model reside in that: the labyrinth sealing device is additionally arranged between the coal injection pipe and the kiln door spray hole, so that the purposes of sealing and locking air and reducing energy waste are achieved.

Description of reference numerals:
1-fixed cover, 2-telescopic pipe, 3-sealed flange, 4-kiln body, 5-coal injection pipe, 6-inner circular pipe, 7-outer circular pipe, 71-annular fixed plate, 72-annular reinforcing plate and 8-rock wool.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 2, the labyrinth coal injection pipe sealing device comprises a fixed cover 1, an extension pipe 2 and a sealing flange 3, wherein the fixed cover 1 fixes a kiln body 4 at a kiln door spray hole, and one end of the extension pipe 2 is fixedly connected with a coal injection pipe 5 through the sealing flange 3; fixed cover 1 establishes including the cover in together, two outer pipes, two pipes are close to the one end body coupling of kiln door orifice, flexible pipe 2 cover is established in the first clearance that interior 6 outer walls of pipe and the formation of outer round pipe 7 inner wall, the inner wall of flexible pipe 2 forms the second clearance with the outer wall of interior pipe 6, the outer wall of flexible pipe 2 forms the third clearance with the inner wall of outer round pipe 7, it has rock wool 8 all to fill in second clearance and the third clearance, flexible pipe 2 is when flexible, owing to there is rock wool 8 to fill, remain sealed throughout between kiln door orifice and the coal injection pipe 5, it is extravagant to reduce to cause the unnecessary energy because of the cold air gets into.
Furthermore, one end of the outer circular tube 7 close to the kiln door spray hole extends outwards along the circumferential direction to form an annular fixing plate 71, one end of the outer circular tube 7 far away from the kiln door spray hole extends outwards along the circumferential direction to form an annular reinforcing plate 72, the fixing cover 1 is fixed at the kiln door spray hole through an expansion bolt penetrating through the annular fixing plate 71, and the inner diameter of the fixing cover 1 is larger than the diameter of the kiln door spray hole.
The utility model discloses an add between coal-injection pipe and kiln door orifice and establish labyrinth sealing device, realize sealed lock wind, reduce the extravagant purpose of the energy.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
