Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln tail anti-falling structure. Background Art

[0002] Solid waste incineration generally uses a rotary kiln plus a secondary combustion chamber. In the incineration of hazardous waste, in order to ensure the removal rate of dioxins, the temperature of the secondary combustion chamber must reach above 1100 degrees. In this case, the temperature at the tail end of the rotary kiln connected to the secondary combustion chamber will be very high, reaching 900 to 1000 degrees or even higher. In this case, the steel structure at the tail end of the kiln will be easily damaged and deformed, and the refractory clay will fall off.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN212179547U, which discloses an anti-falling structure for the tail of a rotary kiln. The utility model has a simple structure, and replaces the ordinary Y-type anchor with a welded steel cage, so that the steel cage and the connecting matrix form an integral structure, so it is not easy to crack and fall off, and the overall strength is guaranteed. Through the return air casing, external cooling gas can enter through the return air casing to cool the local tail of the kiln, so that the tail of the rotary kiln body extending into the second combustion chamber can quickly dissipate heat, thereby increasing the service life of the equipment.

[0004] When in use, the above-mentioned anti-falling structure is only connected by elastic force. However, after long-term use, the elastic force of the elastic force weakens, which easily causes the combustion chamber to be disconnected from the rotary kiln body, the connection is unstable, and the use effect is poor. Therefore, those skilled in the art provide a rotary kiln tail anti-falling structure to solve the problems raised in the above-mentioned background technology. Utility Model Content
