Description

Technical Field

[0001] The utility model relates to an anchor, in particular to a special anchor suitable for suspending microcrystalline plates on a cement rotary kiln body. Background Art

[0002] At present, the refractory material used in the preheater system of the cement clinker production line is high-strength alkali-resistant castable. With the development needs of the cement industry, the treatment of municipal solid waste has been gradually introduced into the cement clinker burning system. At the same time, with the increase of harmful components (such as sulfur, alkali, chlorine, etc.) in coal quality, more scale is generated in the chute, throat, smoke chamber, decomposition furnace, cyclone and connecting pipes of the cement rotary kiln burning system, which affects the operation quality of the rotary kiln; when the scale is serious, it even causes the blockage of the preheater system, resulting in the shutdown accident of the production line. At the same time, there are great potential safety hazards in the subsequent cleaning process, causing a serious passive situation in the production operation of the company.

[0003] In view of the problem of system scaling, refractory material manufacturers have developed a microcrystalline material, which has the advantages of high strength, high wear resistance, good anti-scaling performance, etc. To facilitate the construction of microcrystalline plates, the existing anchors are difficult to achieve the effect of stably fixing microcrystalline plates. The main reason is that the welding point area of the anchor is small, and the anchor is easy to fall off under high temperature and thermal expansion stress, resulting in the fall of microcrystalline plates, which seriously restricts the use effect of microcrystalline plate products.
