Abstract
The utility model discloses a kiln tail iron-protecting structure of a chemical hazardous waste rotary kiln, which comprises at least one layer of structural member arranged on the kiln tail iron-protecting structure; the structural member is vertically fixed on the surface of the kiln tail iron protector; and triangular iron matched with the structural member is reinforced on the side surface of the structural member. The kiln tail iron-protecting structure of the chemical hazardous waste rotary kiln improves the service life of the coating kiln tail iron-protecting castable, overcomes the corrosion of the kiln tail iron-protecting under high-temperature chemistry in the using process, and prolongs the service time of the kiln tail iron-protecting; the service life of the kiln tail iron protection castable is prolonged to more than 1 year from 4-6 months, and the service life of the castable is synchronous with the overall overhaul of the rotary kiln refractory, so that the times of stopping the kiln in one operation period are reduced, and considerable economic benefit is increased for a user unit.
Description
Technical Field
The utility model relates to a useless rotary kiln tail of chemical industry danger protects iron structure belongs to chemical industry equipment technical field.
Background
The kiln tail temperature can reach 950 ℃ -1200 ℃ in the operation process of the chemical hazardous waste rotary kiln, and the kiln tail iron protector is extremely easy to be corroded by high-temperature smoke and materials in a high-temperature environment, so that the kiln tail iron protector is generally wrapped by refractory castable to prolong the service life of the kiln tail iron protector in the high-temperature corrosion environment. Under the influence of the kiln tail iron protection structure of the rotary kiln which is hazardous and waste in the chemical industry, the supporting force of the castable wrapping the kiln tail iron protection is mainly from the anchoring part in a suspension state in the operation process, the anchoring part is influenced by high-temperature corrosion, thermal stress change and the increase of the weight of slag on the surface of the kiln tail castable, the fracture and the reduction of the strength of welding spots are easily caused, so that the castable falls off in a large area, further the kiln tail iron protection is corroded, the kiln is stopped and overhauled, the service life of the kiln tail iron protection is correspondingly shortened, and the overhauling time is prolonged. At present, the service life of the castable for wrapping the kiln tail iron protector is 4-6 months generally, frequent kiln shutdown maintenance not only increases the maintenance cost, but also causes great loss to the normal operation of production units.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a useless rotary kiln tail back iron structure of chemical industry danger has high temperature resistant, corrosion-resistant, improves the characteristics of kiln tail back iron castable life, and life is more than 1 year, realizes maintaining with the rotary kiln resistant material overhaul in step, has solved the service life that the kiln stopping of an operating cycle was examined and repaired and has improved kiln tail back iron.
The kiln tail iron protection structure of the chemical hazardous waste rotary kiln comprises at least one layer of structural member arranged on the kiln tail iron protection; the structural member is vertically fixed on the surface of the kiln tail iron protector; the side face of the structural part is reinforced with triangular iron matched with the structural part, the sheet structural part is vertically arranged on the surface of the kiln tail iron protector, and the triangular iron made of the same material is used for reinforcement, wherein one layer of structural part or two layers of structural parts can be arranged on the kiln tail iron protector, and the structural parts can be arranged according to the structure, the installation mode and the like of the kiln tail iron protector on site.
Further, the structural part is of a sheet structure, and the thickness of the structural part is 10-15 mm.
Furthermore, the structural part and the kiln tail iron protector are welded and fixed, a402 heat-resistant stainless steel welding rod is selected to weld and fix the structural part and the kiln tail iron protector, and the structural part and the kiln tail iron protector are reinforced through triangular iron.
In a preferred embodiment, the structural member is a heat-resistant stainless steel plate having a composition of 0Cr25Ni 20.
In a preferred embodiment, the triangular iron is a heat-resistant stainless steel plate with a composition of 0Cr25Ni20, and the side length of the plate is 1/2 of the structure.
Compared with the prior art, the utility model discloses a useless rotary kiln tail of chemical industry danger protects indisputable structure has improved the life of parcel kiln tail protection indisputable material, has overcome the erosion of kiln tail protection iron under high temperature chemistry in the use, has prolonged the live time of kiln tail protection iron; the service life of the kiln tail iron protection castable is prolonged to more than 1 year from 4-6 months, and the service life of the castable is synchronous with the overall overhaul of the rotary kiln refractory, so that the times of stopping the kiln in one operation period are reduced, and considerable economic benefit is increased for a user unit.
