Description

Technical Field

[0001] The utility model relates to the technical field of clinker calcination, in particular to a raw coal bin for clinker calcination. Background Art

[0002] Clinker calcination is a key step in the production process of portland cement, which involves sintering raw materials at high temperatures to form clinker. This process is usually carried out in a rotary kiln or a vertical preheater-precalciner kiln. During the calcination process, the raw materials are first ground and mixed to form a homogeneous raw meal. Then, this raw meal is fed into the kiln, where a series of chemical reactions occur to form clinker. The calcination reaction is endothermic and occurs in the temperature range of 1300 to 1500 °C. These reactions cause the raw materials to sinter or fuse together to form clinker nodules. The clinker nodules are then cooled, ground, and mixed with additives to produce cement. The calcination process must be carefully controlled to ensure the formation of high-quality clinker. Factors such as temperature, atmosphere, and material composition have a significant impact on the chemical and physical properties of the clinker. The process of clinker calcination can be roughly divided into several stages. Taking the wet rotary kiln as an example, it includes water evaporation, raw meal preheating, raw meal decomposition, clinker calcination, and clinker cooling. These stages occur in different parts of the kiln, including the drying zone, preheating zone, decomposition zone, heat release zone, burning zone, and cooling zone. With the development of society, when raw coal needs to be added during the clinker calcination process, a raw coal bin is used.

[0003] Existing equipment such as CN220448639U, a raw coal bin for clinker calcination, includes a bin body. Hydraulic cylinders are symmetrically arranged at the top of the bin body. A bracket is arranged inside the bin body, and a loosening rod is installed on the surface of the bracket. In the utility model, by installing a bracket inside the bin body and cooperating with the loosening rod installed on the bracket, when the hydraulic cylinder is started, it can drive the bracket to move up and down reciprocally, and then drive the loosening rod to move up and down reciprocally, so as to drive the coal material inside the bin body to be loosened, preventing the occurrence of blanking blockage. The air supply pump conveys air flow to the heater. After the air flow is heated by the heater, it is conveyed to the annular pipe. Cooperating with the use of the air supply sleeve, the heated air flow can be conveyed into the bin body, so that the hot air dries the coal material, and because the temperature of the air flow is heated to a certain extent, the drying efficiency is further accelerated.

[0004] When workers need to calcine clinker, they put the raw coal in the raw coal bin into the processing equipment so that the raw coal can calcine the clinker. However, during the feeding process of the raw coal bin, the raw coal will be squeezed against each other, resulting in the situation that the blanking pipe will be blocked during the feeding process of the raw coal bin, and further leading to the problem that workers need to spend a lot of time unclogging the raw coal bin.
