Abstract
The utility model relates to a kiln ash kiln-entering system. The system comprises a silo-entering elevator, a homogenizing silo, a kiln-entering elevator and a preheater which are sequentially arranged, wherein the homogenizing silo is used for conveying materials into the bottom of the kiln-entering elevator by virtue of a conveying device. An ash returning jar is also arranged in the system, wherein the top end of the ash returning jar is connected with the top end of the silo-entering elevator by virtue of a conveying track driven by a motor; the bottom end of the ash returning jar is connected with the bottom end of the kiln-entering elevator by virtue of the conveying track driven by the motor; a conical discharging pipe is arranged at the lower part of the ash returning jar; a plurality of compressed air inlets communicated with a hollow cavity in the discharging pipe are formed in the outer wall of the discharging pipe. According to the system provided by the utility model, the problems that the conditions of the kiln are unstable, the coal consumption is increased, the yield is decreased and the like because the ingredients of the raw materials entering the kiln are changed due to the influences of returned ash in the kiln when the operation of vertical milling is stopped for a long time are solved.
Description
Technical field
The utility model relates to cement manufacture plant technical field, and a kind of kiln ash enters kiln system specifically.
Background technology
In cement production process, because of the kiln ash that quality coal in cement kiln systems reclaims, in chemical composition, dioxide-containing silica is lower than normal raw material, and calcium oxide, higher than normal raw material, returns the KH value of ash material far above producing raw material.But it is very little to enter kiln raw material composition influence to raw material in the time that low dose of admixture returns ash, therefore, industrially generally add the kiln ash of recovery to carry out finished cement in raw material preparation by doses.Conventionally, kiln ash is sneaked into the process of raw material, that kiln ash is transported in homogenizing storehouse and is mixed with raw material, but under this mode, if when Vertical Mill shutdown period is longer, can cause raising into the rising of kiln raw material saturation ratio, the reduction of silicon rate, aluminium rate, have a strong impact on the steady running of kiln system, cause the production line underproduction, kliner coating rises, falls frequency and increases, clinker quality is defective, and coal consumption, power consumption rise.For ensureing the steady running of kiln system, usually before stopping grinding 5 hours, adjust the composition of mill raw material.
Generally speaking, kiln ash in the past enters kiln flow process to be made, into kiln raw ingredients, larger variation has occurred in the time that Vertical Mill stops, 1 ton of increase pulverized coal consumption per hour after saturation ratio raises, system is also used power consumption increase per hour 80Kwh left and right, the quality of guarantee clinker discharging with air quantity increase.This safe and stable operation to kiln causes very major injury.
Utility model content
The purpose of this utility model is to provide a kind of kiln ash and enters kiln system, and when solution stops Vertical Mill for a long time, because returning ash impact in kiln, entering kiln raw ingredients can change, and causes the problems such as kiln condition is unstable, increase coal consumption, reduction output.
The utility model is for solving the problems of the technologies described above, the technical scheme providing is: a kind of kiln ash enters kiln system, this system is provided with warehouse-in lift successively, homogenizing storehouse, enter kiln lift and preheater, described homogenizing storehouse is transported to the bottom into kiln lift by e Foerderanlage by material, in this system, also establish ash can once, the top of described time ash can is connected with the top of warehouse-in lift by motor-driven delivery track by one, the bottom of described time ash can is connected with the bottom that enters kiln lift by motor-driven delivery track by one, the described bottom of returning ash can is also provided with the discharge nozzle of taper, on the outer wall of discharge nozzle, be provided with multiple compressed air inlets that are connected with discharge nozzle internal cavity.
Described motor is by Controlling System control.
The bottom of described time ash can is also provided with one and returns grey feeding scale.
Described time grey feeding scale is that electron helical claims.
The inside of described time ash can is provided with by motor-driven stirring homogenizing unit.
Described returning on ash can is provided with viewing window.
The beneficial effects of the utility model:
1, kiln ash of the present utility model enters kiln system, and increase equipment is less, only increases by one and returns ash can, one time grey feeding scale and two delivery tracks, and this setup engineering time is short, does not affect normal technical process, does not affect normal production when installation.
2, kiln ash of the present utility model enters kiln system, can, stably by returning returning in ash feeding kiln in ash can, reach stable into kiln raw ingredients by returning grey feeding scale, and kiln condition is good.Meanwhile, also effectively reduce coal consumption and power consumption, stablized production, improved production efficiency, be conducive to the continuous industrial production running of cement producing line.
3, kiln ash of the present utility model enters kiln system, after system stability, can effectively save the time of adjusting operating mode, ensures the stable and high effective operation of kiln, increases the duration of service of refractory materials.
4, kiln ash of the present utility model enters kiln system, returns in ash can and is provided with stirring homogenizing unit, makes back material in ash can either rely on the Gravity Homogenization of self, can utilize again strength and electric power to assist homogenizing, uses item matter even, and finished product stability is good.

Reference numeral: 1, warehouse-in lift, 2, homogenizing storehouse, 3, enter kiln lift, 4, preheater, 5, e Foerderanlage, 6, return ash can, 601, compressed air inlet, 7, delivery track, 8, return grey feeding scale.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model:
A kind of kiln ash enters kiln system, this system is provided with warehouse-in lift 1 successively, homogenizing storehouse 2, enter kiln lift 3 and preheater 4, described homogenizing storehouse 2 is transported to the bottom into kiln lift 3 by e Foerderanlage 5 by material, in this system, also establish ash can 6 once, the top of described time ash can 6 is connected with the top of warehouse-in lift 1 by motor-driven delivery track 7 by one, the bottom of described time ash can 6 is connected with the bottom that enters kiln lift 3 by motor-driven delivery track 7 by one, the described bottom of returning ash can 6 is also provided with the discharge nozzle of taper, on the outer wall of discharge nozzle, be provided with multiple compressed air inlets 601 that are connected with discharge nozzle internal cavity.
