Abstract

The invention relates to a rotary kiln body, in particular to a novel rotary kiln body used for rotary kilns in the industries of cement, chemical engineering and metallurgy. The novel rotary kiln body is mainly composed of a transmission gear, rolling rings, an inner barrel, an outer barrel, zirconium-aluminum cotton heat insulation plates, annular inner barrel supports and heat-resisting bricks. The inner barrel and the outer barrel are both formed by rolling and welding a heat-resisting steel sheet, the annular inner barrel supports and the zirconium-aluminum cotton heat insulation plates are arranged between the inner barrel and the outer barrel, the heat-resisting bricks are arranged on the inner periphery of the inner barrel, the rolling rings and the transmission gear used for enabling the kiln body to rotate are arranged on the periphery of the outer barrel, and the rolling rings and the transmission gear are welded with the outer barrel. Due to the technical scheme, the heat insulation layer composed of the inner barrel, the annular inner barrel supports and the zirconium-aluminum cotton heat insulation plates is added between the heat-resisting bricks and the outer barrel, and the purposes of guaranteeing temperature in the kiln body, improving production efficiency, lowering energy consumption and prolonging the service life of the kiln body are achieved.

Description

A kind of Novel rotary kiln body

Technical field

The present invention relates to a kind of rotary kiln body, mainly refer to a kind of Novel rotary kiln body of using on cement, chemical industry, metallurgical rotary kiln.

Background technology

At present, at cement, chemical industry, in metallurgical industry, a kind of equipment that producer is often used is exactly rotary kiln, this rotary kiln is mainly by kiln cylinder body, rolling ring, travelling gear and heat resisting brick form, wherein, kiln cylinder body is made by steel plate, the heat-resisting brick inner side at kiln cylinder body forms refractory layer, for cement, chemical products, the manufacture of metallurgical workpiece provides thermal environment, yet, a large amount of practices show, the rotary kiln body of this double-layer structure formula, exist many deficiencies, as: the heat resisting brick coefficient of heat conduction is larger, in the process of producing, heat resisting brick can conduct by kiln cylinder body a large amount of heats in atmosphere, cause the loss of mass energy, simultaneously, conduction because of heat resisting brick, the surface temperature of kiln cylinder body is raise greatly, steel plate and the airborne oxygen of kiln cylinder body have been accelerated, the chemical reaction velocity of etchant gas, also just accelerated the damage progress of rotary kiln cylindrical shell, cause unnecessary economic loss.

Summary of the invention

The object of the invention is to overcome deficiency of the prior art, a kind of Novel rotary kiln body is provided, in the process of utilizing this Novel rotary kiln body to produce; reach minimizing hear rate, improve output, protection kiln body; extension device service life, the object reducing production costs.

For solving the problems of the technologies described above, a kind of Novel rotary kiln body of the present invention, by travelling gear, rolling ring, outer cylinder body, annular inner barrel support, inner barrel, zirconium aluminum wool thermal insulation thermal insulation board, heat resisting brick forms, inner barrel and outer cylinder body are welded by heat-resisting steel sheet and plate rolling, between inner barrel and outer cylinder body, be provided with zirconium aluminum wool thermal insulation thermal insulation board and annular inner barrel support, on the circumference of the inside of inner barrel, be provided with heat resisting brick, the travelling gear that is provided with rolling ring and rotates for kiln body on the periphery of outer cylinder body, rolling ring is connected with outer cylinder body periphery by welding procedure with travelling gear.Annular inner barrel support is connected with the outer circumference surface of inner barrel by welding.

Owing to having adopted such scheme: in the process of cement, chemical products, metallurgical work piece production; heat in rotary kiln body; under the effect of the heat-insulation layer forming at inner barrel, annular inner barrel support, outer cylinder body and zirconium aluminum wool thermal insulation thermal insulation board; the outside transmission speed of kiln intimate heat has slowed down; temperature in kiln body is maintained; the temperature on outer cylinder body surface is significantly reduced, thus the multipurpose that reaches protection rotary kiln body, saves the energy, reduces production costs.
