Abstract
The utility model provides a kiln dust treatment device of a rotary cement kiln, which comprises a kiln tail dust collector, a raw material storehouse, a small raw material bin and a rotary kiln. The kiln dust treatment device is characterized in that: the kiln dust treatment device is further provided with a kiln dust bin, and kiln dust collected by the kiln tail dust collector enters the kiln dust bin through a conveying device; a metering balance is arranged at a discharging opening at the bottom part of the kiln dust bin, and the metered kiln dust and metered raw materials in the raw material storehouse enter the small raw material bin through the conveying device after being mixed together; a metering balance is also arranged at the bottom part of the small raw material bin, and a mixture of the metered raw materials and the kiln dust enters the rotary kiln. The kiln dust entering the kiln is separately metered; the kiln dust can be reduced and even stopped from entering the kiln when a pre-heater is slightly blocked, so as to restore the abnormal running state of the rotary kiln; when the pre-heater is not blocked, the kiln dust feeding quantity is increased or maintained in the normal state, and the kiln dust bin is emptied as far as possible to prepare for the treatment of the next abnormal state.
Description
Technical field
The utility model relates to the kiln ash handling equipment of cement rotary kiln.
Background technology
In the cement rotary kiln production method, the kiln ash that kiln tail dust-precipitator is collected is generally sent in little storehouse of kiln tail or the raw material storage vault by level or vertical transportation machinery, is metered to kiln jointly in company with going into the kiln raw material then.It is simple to do method like this, but because the kiln ash contains the more harmful element that the revolution kiln tail preheater is stopped up, can not control its feed quantity separately in addition, thereby often stops kiln owing to preheater stops up, and influence is produced, and causes very big economic loss.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of kiln ash handling equipment of improved cement rotary kiln, goes into the metering separately of kiln kiln ash, does not influence the normal operation of rotary kiln when preheater slightly stops up.
The kiln ash handling equipment of the utility model cement rotary kiln, comprise kiln tail dust-precipitator, raw material storage vault, the little storehouse of raw material, rotary kiln, it is characterized in that also being provided with kiln ash storehouse, the kiln ash that kiln tail dust-precipitator is collected enters into kiln ash storehouse by conveying device, kiln ash Cang Dibuchuliaokou is provided with weigher, through grey the mixing by conveying device through the raw material that measure of the kiln of metering entering the little storehouse of raw material with the raw material storage vault, bottom, the little storehouse of raw material is provided with weigher, goes into rotary kiln through the raw material of metering and the mixture of kiln ash.
Kiln ash handling equipment of the present utility model, can when preheater slightly stops up, reduce so that stop the kiln ash and go into kiln to save the abnormal state of rotary kiln running, do not have when stopping up by normal condition or add Dayao ash feed quantity at preheater, vacate kiln ash storehouse as far as possible and be the preparatory condition of abnormal state processing next time.
Technology condition is preferably: the capacity in kiln ash storehouse or dress ash amount per hour feed 5 to 7 times of raw material amount (mixture of raw material and kiln ash) for rotary kiln.The measuring accuracy of kiln ash weigher is identical with the raw material weigher, and its measures range is 3% to 30% of a raw material weigher.
Advantage of the present utility model:
Be provided with simply, do not change the processing step or the technical conditions of original rotary kiln substantially.Go into the metering separately of kiln kiln ash, when preheater slightly stops up, do not influence the normal operation of rotary kiln.When having obstruction, preheater can or not add Dayao ash feed quantity by normal condition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 9 weighers, 10 rotary kilns of the little storehouse of 4 weighers, 5 raw material storage vaults, 6 weighers, 7 conveying devices, 8 raw material, 1 kiln tail dust-precipitator, 2 conveying devices, 3 kilns ash storehouse
The specific embodiment
(arrow is represented the material feedstock direction among the figure) as shown in the figure, the kiln ash handling equipment of the utility model cement rotary kiln, comprise kiln tail dust-precipitator 1, kiln ash storehouse 3, raw material storage vault 5, the little storehouse 8 of raw material, rotary kiln 10, the kiln ash that kiln tail dust-precipitator 1 is collected enters into kiln ash storehouse 3 by conventional level or vertical transportation machinery (conveying device 2), kiln ash storehouse 3 bottom discharge mouths are provided with weigher 4, mix by level or vertical transportation machinery (conveying device 7) through the kiln ash of metering and raw material that raw material storage vault 5 measures through weighers 6 and to enter the little storehouse 8 of raw material, 8 bottoms, the little storehouse of raw material are provided with weigher 9, go into rotary kiln 10 through the raw material of metering and the mixture of kiln ash.
Claims (1)
1. the kiln ash handling equipment of a cement rotary kiln, comprise kiln tail dust-precipitator, raw material storage vault, the little storehouse of raw material, rotary kiln, it is characterized in that also being provided with kiln ash storehouse, the kiln ash that kiln tail dust-precipitator is collected enters into kiln ash storehouse by conveying device, kiln ash Cang Dibuchuliaokou is provided with weigher, through grey the mixing by conveying device through the raw material that measure of the kiln of metering entering the little storehouse of raw material with the raw material storage vault, bottom, the little storehouse of raw material is provided with weigher, goes into rotary kiln through the raw material of metering and the mixture of kiln ash.
