Abstract
Provided is a rotary kiln head sealing device. A rotary kiln head is sleeved with the sealing device. The sealing device comprises a friction base, friction plates and a friction ring, wherein the friction plates are connected with the friction base, and the friction ring makes contact with the friction plates in a sealed mode. The friction ring is connected to the kiln head in a sleeving mode and rotates together with the kiln head. A conical sleeve formed by welding steel plates is used as the friction base. The rectangular friction plates with edges being overlaid mutually are laid on the conical surface of the conical sleeve around the circle center. The tail ends of the rectangular friction plates are in compression joint with the surface of the friction ring in a sealed mode. A rubber gasket is arranged on the contact surfaces of the friction plates and the friction ring. The contact surfaces of the friction plates and the friction ring are in seamless contact, so that the ideal sealing effect is achieved, and the probability of air leakage and material leakage of a rotary kiln is greatly reduced; meanwhile, the sealing device is more convenient to mount and use.
Description
Technical field
The invention belongs to rotary kiln technical field, particularly a kind of kiln end sealing device of rotary kiln.
Background technology
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 cylindrical shell exists the distortion such as oval, bending, between pivoting part and fixed part, there is the three-dimensional gap of the radial direction of constantly change, axis and hoop.When being subject to the fluctuation of random positive/negative pressure, can cause leaking out, leaking the phenomenon of expecting, and relatively more serious, and the sealing effectiveness of these hermetically-sealed constructions is very undesirable, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of good sealing effect, effectively prevent the revolution kiln end sealing device of expecting that leaks out.
For realizing the object of the invention, there is provided following technical scheme: a kind of revolution kiln end sealing device, described sealing device is sheathed on revolution kiln hood, it is characterized in that comprising friction seat, connecting wearing piece with friction seat and contact the ring friction sealed with wearing piece, ring friction is socketed on kiln hood and rotates with kiln hood, friction seat is the taper sheath that Plate Welding becomes, the conical surface of taper sheath is equipped with around the center of circle the stacking rectangle wearing piece in mutual edge, and rectangle wearing piece end crimps with ring friction surface and seals.The contact surface of wearing piece and ring friction is provided with rubber blanket.
As preferably, wearing piece arranges bolt with the conical surface of taper sheath and is fixedly connected with.
As preferably, be provided with L-type sealing ring in friction seat, L-type sealing ring is sheathed on revolution kiln hood.
As preferably, wearing piece material is 0Cr18Ni9.
As preferably, ring friction is polyethylene ring.
Beneficial effect of the present invention: wearing piece of the present invention contacts with the contact surface of ring friction is seamless, thus reaches desirable sealing effectiveness, greatly reduces the phenomenon that rotary kiln leaks out, leaks material, installs and uses convenient simultaneously.
