Abstract

The utility model relates to a separated room vertical preheater which is characterized in that the utility model is composed of an upper loading chamber (1), a support body (5) and a lower loading chamber (8), wherein the upper loading chamber is arranged above the support body, a plurality of respectively independent storage bunkers (2) are arranged along the circumference of the support body under the upper loading chamber, the bottom of each storage bunker is communicated with each corresponding preheating bunker (6) through baiting tubes (4), and the preheating bunkers are communicated with the lower loading chamber which is connected with a rotary kiln (9). The utility model realizes the counter current of flue gas and materials, and the materials can be sufficiently preheated. When a single preheating bunker breaks down, the single preheating bunker can be stopped to be repaired and other bunkers can work normally.

Description

Novel branch storehouse shaft preheater
Technical field:
The utility model relates to quickened lime production unit technical field, a kind of novel branch storehouse shaft preheater.
Background technology:
At present, the production unit of calcined by rotary kiln system, preheater, water cooler, rotary kiln also are called three big main frames of quickened lime calcined by rotary kiln system.Wherein the form of preheater mainly contains two kinds:
1, chain comb formula preheating machine, principle of work is: the material above movably grid section drives in the preheating machine is done slowly motion, and material bed the high temperature hot gas of coming out in rotary kiln is passed and moved carries out heat exchange.This device structure complexity, drive disk assembly is many, and operation factor is low, the manufacturing cost height, and also the bed of material position on the grid section is static relatively, and the bed of material is heated inhomogeneous, has influenced the even calcining in the rotary kiln.
2, ring storehouse formula shaft preheater is made up of several parts such as top feed compartment, body, push rod device, bottom feed compartments.Material regularly is discharged into preheater by vibratory feeder in hopper in the storage bunker of top; Its body part is cylindrical, material drops in the annular feed bin that whole body part builds by laying bricks or stones, and bed thickness is bigger, and the hot flue gas of kiln tail enters feed bin by the slotted eye of material-pulling device top, material is carried out preheating, and the flue gas after the exchange is discharged by feed bin top flue.Because charging system has a large amount of movement parts to constitute, run duration breaks down easily; When especially annular feed bin breaks down in some or several push rod device, will cause the accumulation of material, the internal heat wind flow is obstructed, influence the pre-heat effect of material, also can cause when serious stopping production at this place.
Summary of the invention:
In order to overcome the deficiency on the prior art, the utility model provides a kind of novel branch storehouse shaft preheater.The technology that it adopts flue gas and material adverse current makes the sufficient preheating of material, if single especially at work heating cabinet goes wrong, can be single immediately the shutdown maintenance, other bin still can works better, has improved efficient.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
This novel branch storehouse shaft preheater is made up of top feed compartment, supporting body and bottom feed compartment, supports
There is the top feed compartment body top; The below of top feed compartment is along independently storage bunker of several difference is arranged on the circumference of bracing frame body; The bottom of each storage bunker is connected by the tremie pipe preheating storehouse corresponding with each; The preheating storehouse is connected with the bottom feed compartment; The bottom feed compartment connects rotary kiln.
The branch storehouse shaft preheater that this is novel, its each independently storage bunker be cone structure, the bottom of storage bunker connects tremie pipe, tremie pipe is connected with a rod valve.
The branch storehouse shaft preheater that this is novel, its each preheating storehouse is the regular polygon structure, and the top in preheating storehouse is connected to exhaust duct, and some blanking arches are arranged at the bottom, between blanking arch and the bottom feed compartment wind box are arranged.
The branch storehouse shaft preheater that this is novel, its top add the level gage that is used to detect height of materials also are housed on the feed bin.
The branch storehouse shaft preheater that this is novel, the below device in its each preheating storehouse has push rod device.
Owing to adopted technique scheme, the utlity model has following superiority:
The branch storehouse shaft preheater device that this is novel, utilize hot flue gas of kiln tail and normal temperature material to carry out the heat exchange of gas thing, make material before entering rotary kiln, just be preheating to more than 900 ℃, realize about 20% predecomposition, its waste gas can also be with a wind preheating of kiln hood, thereby being reached, hot flue gas in the whole rotary system makes full use of, energy-efficient, be widely used in fields such as metallurgy, chemical industry, building materials.Simple in equipment has reduced manufacture difficulty, has alleviated weight of equipment, makes operation and controls conveniently, and running efficiency significantly improves.

Embodiment:
As shown in FIG.: this novel branch storehouse shaft preheater is made up of top feed compartment (1), supporting body (5) and bottom feed compartment (8); There is the top feed compartment bracing frame body top, the below of top feed compartment is along independently storage bunker (2) of several difference is arranged on the circumference of bracing frame body, the bottom of each storage bunker is connected by tremie pipe (4) the preheating storehouse (6) corresponding with each, the preheating storehouse is connected with the bottom feed compartment, and the bottom feed compartment connects rotary kiln (9).Its each independently storage bunker be cone structure, the bottom of storage bunker connects tremie pipe, tremie pipe is connected with a rod valve (10).Its each preheating storehouse is the regular polygon structure, and the top in preheating storehouse is connected to exhaust duct (3), and some blanking arches (11) are arranged at the bottom, and a wind box (12) is arranged between blanking arch and the bottom feed compartment.Its top adds also is equipped with the level gage (13) that is used to detect height of materials on the feed bin, the below device in its each preheating storehouse has push rod device (7).
After material enters the top feed compartment, separately enter each tremie pipe naturally, by in each the independent preheating storehouse (6) in each tremie pipe inflow preheater supporting body, can regulate excellent valve (10) the control mass flow on the filling tube therebetween again along cone storage bunker (2).From the hot flue gas of rotary kiln (9) tail by push rod device push rod cup the place ahead blanking arch (11) and the up process of wind box (12) in the material formation adverse current that falls, pass material bed realization heat exchange, flue gas after the exchange enters smoke processing system through the exhaust duct (3) of top, preheating storehouse, and the material after the preheating is pushed the bottom feed compartment to by push rod device (7) and entered rotary kiln (9).
