Embodiment 1

[0018] A multi-element smoke-type shrinkage hanger for the shrinkage part of the smoke chamber of a cement kiln preheater, including a main board 1 whose height is tailored according to the height of the shrinkage. The protective cover 2 is installed in the middle of the protective cover 2. There is an installation and fixing hole 3. The installation and fixing hole 3 is fixed on the shrinking wall of the smoke chamber through the main board 1 with bolts. The lower end of the main board 1 is provided with a connecting ear seat 4. There is a connection fixing hole 5, and the connecting ear seat 4 is connected with another adjacent main board 1 through the connecting and fixing hole 5 on the connecting ear seat 4 through bolts. Further explanation: the four corners of each main board are 90°, The lower end does not need to be curved, and the assembly ends up in a cylindrical shape.

Embodiment 2

[0020] A multi-element smoke-type shrinkage hanging piece for the shrinkage part of the smoke chamber of a cement kiln preheater, including a main board 1, the height of the main board is tailored according to the height of the shrinkage, and a tooth-shaped hook is provided on the back of the upper end of the main board 1 6. There is an installation protective cover 2 under the main board 1, and the installation and fixing hole 3 is arranged in the middle of the installation protective cover 2. The installation and fixing hole 3 is fixed on the shrinking wall of the smoke chamber with bolts passing through the main board 1, and the lower end of the main board 1 is provided with connecting ears. Seat 4, the center of the connecting ear seat 4 is provided with a connection fixing hole 5, the connecting ear seat 4 is connected with another adjacent main board 1 through the connection fixing hole 5 on the connecting ear seat 4 by bolts, and the tooth-shaped hook 6 Hang directly on ...

Abstract

The invention relates to a multi-element composite smoke chamber type necking hanging piece for a preheater of a cement kiln. The multi-element composite smoke chamber type necking hanging piece comprises main plates which are smooth; the main plates are classified into two types, namely the main plates with mounting protective sleeves arranged at the upper parts and the lower parts of the back surfaces of the main plates, and the main plates with tooth-shaped hooks arranged on the upper parts of the back surfaces of the main plates, wherein the tooth-shaped hooks are connected with flanges ona smoke chamber necking, and mounting protective sleeves are arranged at the lower parts of the back surfaces of the main plates; a mounting and fixing hole is formed in the center of each mounting protective sleeve; connecting lug seats are arranged at the bottom ends of the main plates; connecting and fixing holes are formed in the connecting lug seats; and the centers of the connecting and fixing holes are fixed by bolts. A complete inner cylinder can be formed by connecting a single row of main plates, and finally a square assembly and a cylindrical assembly are formed. The multi-elementcomposite smoke chamber type necking hanging piece is good in crust resistance and hardly generate any crust after being used, the situation that the kiln is shut down to treat the crust is avoided, the cost is reduced, and the production efficiency of a cement plant is improved; the multi-element composite smoke chamber type necking hanging piece is anti-corrosion, anti-oxidation, heat-resistant,wear-proof and crust-resistant, is long in life cycle, and does not require continual replacement, the cost is reduced and the manpower is saved; and the size of the multi-element composite smoke chamber type necking hanging piece can be designed as need for accomplishment of mounting and use, and the production is more convenient and quicker.

Description

technical field [0001] The invention specifically relates to a multi-element composite smoke-type shrinkage hanging piece for a cement kiln preheater. Background technique [0002] At present, the shrinkage part of the domestic cement kiln smoke chamber is used with welded anchors and castables. Due to the high temperature and severe crusting of this part, the preheater will be blocked. The blocked material will cause the change of wind speed to affect production and cause blockage. The production of the material is stopped, and the kiln will be shut down from January to February to deal with the crusting of the castables. Since the workers clean up the crusts, it is quite troublesome to deal with, and the part is easy to fall and damage. It is necessary to fix the castables in the smoke chamber with glue. Expensive costs, analysis of the loss cost caused by the one-day shutdown of the cement production enterprise: the loss cost of the 2500T / D cement production line is about...
