Abstract
The utility model discloses a kiln head sealing device of a rotary kiln. The kiln head sealing device comprises a cold air sleeve and a kiln head cover which are arranged on a rotary kiln cylinder and further comprises a truncated cone-shaped flange. One end of the truncated cone-shaped flange is welded on the kiln head cover, while the other end of the truncated cone-shaped flange is connected to the cold air sleeve. The outer wall of the truncated cone-shaped flange is fixedly connected with a friction plate, a sealing plate, and a pressing plate sequentially from the inside to the outside sequentially via bolts. The friction plate is tightly attached onto the cold air sleeve. The outer side of the pressing plate is provided with a tensioning device. According to the utility model, by virtue of seamless contact of contact faces among the cold air sleeve, the friction plate, the sealing plate, and the pressing plate, the ideal sealing effect is achieved, the phenomena of air and material leakage of the rotary kiln are greatly reduced, and the installation and the utilization are more convenient at the same time.
Description
Technical field
The utility model belongs to rotary kiln technical field, particularly a kind of kiln end sealing device of rotary kiln.
Background technology
The kiln hood sealing of rotary kiln, the sealing of kiln tail all play and connect the superior and the subordinate's equipment in rotary kiln, are connected and fixed the sealing function between parts and pivoting part.
Not only there is high temperature, high dust, negative pressure process environments in the kiln tail of rotary kiln, there is the comprehensive compound movement such as revolution, swing, axial float in kiln tail end simultaneously, and there is the distortion such as oval, bending in cylindrical shell, between pivoting part and fixed part, exist constantly change radially, the axial and three-dimensional gap of hoop.Therefore, under this extremely complicated process conditions, require kiln hood sealing, the sealing of kiln tail should there is following features: not leak out, do not leak ash, do not leak material, high temperature resistant, wear-resistant, long-life, high reliability, easy for installation, non-maintaining use and low Integrated using cost.And existing kiln head and tail sealing device adopts the hermetically-sealed constructions such as cylinder type, labyrinth, flap graphite mostly, when being subject to random positive/negative pressure fluctuation, can cause the phenomenon of leaking out, leaking material, and more serious, and the sealing effectiveness of these hermetically-sealed constructions is very undesirable.
Utility model content
Utility model object: the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of kiln end sealing device of rotary kiln of good sealing effect
Technical scheme: for realizing above-mentioned utility model object, the technical solution adopted in the utility model is a kind of kiln end sealing device of rotary kiln, comprise the cold wind shroud and the kiln head cover that are arranged on cylinder of rotary kiln, also comprise truncated cone-shaped flange, described truncated cone-shaped flange one end is welded on kiln head cover, the other end is connected on cold wind shroud, outer wall at described truncated cone-shaped flange is fixedly connected with friction plate, sealing plate and pressing plate with bolt from inside to outside successively, wherein said friction plate is close on cold wind shroud, in the outside of described pressing plate, is provided with tensioning apparatus.
Wherein, sealing plate is preferably the stainless steel sealing plate of 1Cr18Ni9Ti model, and described pressing plate is preferably spring steel pressing plate, makes so the existing some strength of sealing plate and pressing plate have again enough elasticity, and whole sealing device can be tightly fitted on the cylindrical shell of rotary kiln.
Described friction plate preferably adopts the stratiform friction plate being comprised of aluminosilicate refractory fiber layer, heat-resistant steel wire stratum reticulare and ceramic fibre layer of cloth successively.Such layer structure has increased the wear resistence of friction plate.
Described tensioning apparatus comprises steel wire rope, pulley gear, support and weight, and wherein, described pulley gear is fixed on support, and described steel wire rope two ends hang weight, and steel wire rope is pressed in the outside of described pressing plate by pulley gear.Such tensioning apparatus not only has enough elasticity, and convenient adjusting.
Operation principle: during the utility model normal operating, rotary kiln is interior in negative pressure, and outside cold wind can only enter in rotary kiln the radial clearance between friction plate, sealing plate, pressing plate and cylinder of rotary kiln.The existing some strength of friction plate, sealing plate, pressing plate that kiln end sealing device adopts has again enough elasticity, friction plate, sealing plate, pressing plate are tightly fitted on cylinder of rotary kiln, reduce as much as possible the radial clearance between seal and cylinder of rotary kiln, guarantee that sealing effectiveness reaches best.
Beneficial effect: the utility model compared with prior art, by the seamless contact of the contact-making surface between cold wind shroud, friction plate, sealing plate and pressing plate, thereby reach desirable sealing effectiveness, greatly reduce rotary kiln and leak out, leak the phenomenon of expecting, install and use convenient simultaneously.
