Novel feeding device for decomposing furnace for cement kiln

Abstract

The invention discloses a novel feeding device for a decomposing furnace for a cement kiln. The novel feeding device comprises an area I, an area II, an area III and an area IV, wherein the area I comprises a blanking pipe with the round top and the square bottom, and the blanking pipe is arranged obliquely; the area II is positioned below the feeding port of the area I, the area III is positionedunder the area II, and the area III and the area II are positioned on the oblique plane with the same gradient; and the area IV is connected to the bottom end of the area III and comprises a materialscattering plate which is tilted downwards. The novel feeding device for the decomposing furnace enhances the dispersion of materials to ensure the effective mixing of the materials with the rising high-temperature airflow in the decomposing furnace, so that all the materials are taken to a 5-stage preheater and deposited into the kiln. Thus, raw materials can be fully and uniformly decomposed, which is conducive to the calcination quality and an energy saving effect.

Description

technical field [0001] The invention belongs to the technical field of cement kiln production, in particular to a novel feeding device for a cement kiln calciner. Background technique [0002] All new dry-process clinker production lines in my country adopt traditional circular pipes with a large oblique angle to feed the calciner into the calciner. This design is difficult to achieve the effect of dispersing the powder on the material, resulting in two kind of disadvantage. One is that when the insufficiently dispersed material powder enters the calciner and the updraft does not increase, part of the material powder will directly fall into the bottom and enter the kiln. This kind of material will have a certain impact on the quality of clinker. In this case, we usually adopt a solution to increase the amount of coal head to increase the calcination temperature. In addition, increase the power of the high-temperature fan to increase the air volume and enhance the upward forc...

[0002] All new dry-process clinker production lines in my country adopt traditional circular pipes with a large oblique angle to feed the calciner into the calciner. This design is difficult to achieve the effect of dispersing the powder on the material, resulting in two kind of disadvantage

One is that when the insufficiently dispersed material powder enters the calciner and the updraft does not increase, part of the material powder will directly fall into the bottom and enter the kiln. This kind of material will have a certain impact on the quality of clinker. In this case, we usually adopt a solution to increase the amount of coal head to increase the calcination temperature. In addition, increase the power of the high-temperature fan to increase the air volume and enhance the upward force of the updraft to bring the material into the five-stage preheater. Increase the power of the high-temperature fan , will virtually increase energy consumption
