Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a kiln head air inlet structure. Background Art

[0002] The rotary kiln is composed of processes such as gas flow, fuel combustion, heat transfer and material movement. The rotary kiln is about how to make the fuel burn fully and the heat of the fuel combustion can be effectively transferred to the material. After the material receives the heat, a series of physical and chemical changes occur and finally the finished clinker is formed. Therefore, the rotary kiln head is equipped with an air intake structure to facilitate auxiliary fuel combustion and increase the demand for the rotary kiln. The rotary kiln head is equipped with an air intake structure, and the air intake structure needs to control the air volume according to demand to reduce energy consumption and increase waste heat power generation.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN203478939U, which discloses a rotary kiln air inlet device. The utility model comprises: a fan, a straight pipe and a spiral pipe, and is characterized in that: a fan support is welded to the rotary kiln cylinder, the fan is installed on the fan support, the straight pipe is supported by a sliding support, one end of the straight pipe is connected to the fan outlet, and the other end is connected to the spiral pipe, a metal flexible pipe is provided on the spiral pipe and communicates with the rotary kiln cylinder, and the two sets of straight pipes are connected by an interconnecting pipe. Since the spiral pipe is arranged in a spiral line toward the air supply port in the rotary kiln cylinder, the calcined petroleum coke in the rotary kiln can only bury one air supply port at a time, and does not affect the normal air supply of other air supply ports.

[0004] Although the above-mentioned rotary kiln air inlet device solves the problem of normal air supply of multiple air supply holes, the rotary kiln works in a high-temperature state. During the operation, the air inlet structure is not convenient for adjusting the air volume according to the combustion conditions of the rotary kiln fuel, which reduces the use function of the air inlet structure and causes large energy consumption. At the same time, the single air inlet structure leads to certain limitations in the use of the air inlet structure temperature control, which reduces the use effect of the kiln tail air inlet structure.
