Problems solved by technology

The spreading effect of spreading devices of different manufacturers is not the same, and it is difficult to adjust in response to the phenomena of material collapse and material blocking
The raw meal powder in the calciner of the preheater cannot be fully dispersed, and the phenomenon of material flushing and internal back-mixing occurs from time to time, and the gas-solid two-phase heat transfer efficiency is low

Abstract

The invention relates to a combined adjustable material spreading device. The device comprises a material spreading box, a material spreading plate and an adjusting device. The material spreading plate is arranged below the material spreading box, the adjusting device is connected with a preheater connecting pipe or a decomposing furnace, the adjusting device is arranged below or above the material spreading plate, one end of the material spreading plate is connected with the adjusting device, and the adjusting device can adjust the position of a stretching plate of the material spreading plate into a preheater or into the decomposing furnace. The contacting area of the material spreading plate and materials is changed by adjusting the position of the material spreading plate stretching into the preheater or the decomposing furnace, and the adjustment to the blanking angle of the preheater can be achieved. Dispersion effect of the materials is guaranteed, heat exchange efficiency of a preheater system is improved, materials stuck to the material spreading plate can be cleaned timely, and material blocking and material collapsing occurring at the material spreading plate are avoided.

Description

technical field [0001] The invention relates to a material spreading device for improving the heat exchange efficiency of materials, in particular to a material spreading device for improving the heat exchange efficiency of materials which is applied to the calciner system of a preheater in the cement industry. Background technique [0002] The heat consumption of clinker firing is an important technical and economic indicator of the firing system besides clinker output. The level of firing heat consumption is directly related to the cost of cement and the economic benefits of the plant. The principle of the material spreading device used in the preheater calciner of the existing cement industry is to use the impact force of falling materials to hit the material spreading plane of the material spreading device to disperse automatically, so the effect of material spreading is not adjustable. The spreading effect of spreading devices of different manufacturers is not the same...
