It is used in cement manufacturing, metallurgy, chemical industry and environmental protection. The equipment consists of a cylinder, support device, transmission device, etc. The kiln body is arranged at an incline and supported by rollers. In order to reduce the impact of high temperature radiation on the roller oil tank and journal, heat insulation structure is required for protection.

[0003] Currently, Chinese utility model patent CN221005898U discloses a protective heat insulation device for a cement rotary kiln support roller. Although the heat insulation cover in this heat insulation structure has a large protective area and the bottom can be rigidly fixed by the bracket for stable operation, there are still other problems in use. For example, it is not convenient to disassemble and assemble quickly. When the heat insulation cover malfunctions or needs maintenance, it needs to be removed from the support by personnel. Since it is directly tightened by screws, personnel need to use tools to assist in the removal, which is time-consuming and laborious, and its practicality is low. Utility Model Content

[0004] The purpose of this utility model is to provide a heat insulation structure for a cement rotary kiln, which has the advantage of being easy for personnel to quickly assemble and disassemble.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cement rotary kiln heat insulation structure, including two support seats, with fixed seats welded to the front and back of each support seat, a heat insulation cover provided on the top of each support seat, and support plates symmetrically welded to the bottom of the heat insulation cover. A guide groove is provided on the top of each fixed seat, and the bottom end of the support plate extends into the interior of the guide groove. A fixed frame is bolted to the front and back of each support seat, and a limit plate is provided inside the fixed frame. A limit groove for cooperating with the limit plate is provided inside the support plate, and a limit spring is bolted between the back of the limit plate and the fixed frame through a spring fixing piece.

[0006] The above technical solution allows for quick and easy disassembly and assembly, is simple and convenient to operate, eliminates the need for tools, improves the efficiency of personnel inspection and maintenance, and has high stability and practicality.

[0007] The present invention is further configured such that a groove is provided on the front side of the limiting plate, and a roller is rotatably connected to the inside of the groove through a bearing.

[0008] By adopting the above technical solution, the friction between the support plate and the front of the limiting plate can be reduced by setting the groove and roller.

[0009] The present invention is further configured such that a fixing plate is fixedly sleeved on the surface of the limiting plate, and the diameter of the fixing plate is larger than the inner diameter of the limiting groove.

[0010] The above technical solution allows for the setting of a fixed plate to limit the position of the limiting plate, preventing it from being excessively pushed out by the limiting spring.

[0011] The present invention is further provided that the top of the fixing base has two mounting holes.

[0012] The above technical solution allows for easy fixing of the mounting base with screws by the installation holes.

[0013] The present invention is further configured such that the surfaces of the heat insulation cover and the support plate are coated with anti-corrosion coating.

[0014] By adopting the above technical solution, the anti-corrosion and moisture-proof effects of the heat insulation cover and support plate surface can be improved through the application of anti-corrosion coating.

[0015] The present invention is further configured such that the limiting spring is made of carbon spring steel.

[0016] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.

[0017] In summary, this utility model has the following beneficial effects:

[0018] First, the support roller is lifted onto the support base and secured with screws. After the support roller is secured, the heat insulation cover is lifted. After the heat insulation cover is lifted, the bottom support plate is inserted into the guide groove in the fixed base and pushed inward. When the support plate is pushed to contact the limit plate, the limit plate is pressed inward. When the limit plate is pressed, it will retract into the fixed frame and compress the limit spring. When the limit plate is pressed all the way down, the support plate is pushed inward until the limit groove in the support plate and the limit plate are aligned. After the limit plate and the limit groove are aligned, the limit plate will reset and move forward into the limit groove. This allows for quick disassembly and assembly by personnel. The operation is simple and convenient, eliminating the need for tools and improving the efficiency of personnel inspection and maintenance. It has high stability and practicality.
