Description
Technical field
The utility model belongs to calcium oxide production technical field, more particularly to a kind of calcium oxide production system.
Background technology
Calcium oxide is commonly called as quick lime, and typically lime stone is made after calcining at high temperature, and certain applications field is to quick lime
The fineness of powder has requirements at the higher level, to meet customer requirement, and the quick lime that baked first need to be machined through grinding, then through whirlwind point
After device, quality can meet customer requirement substantially, but due to the influence of existing raw limestone, cause the quick lime matter burnt till
Amount is not good enough, shows as raw burn greatly, the calcium lime powder quality prepared by existing design technology is unstable, wherein inevitably pressing from both sides
With insufficiently burnt agstone, and then influence the main content of calcium lime powder, it would be highly desirable to improve.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of calcium oxide production system
System, the problems such as solving to be entrained with insufficiently burnt lime stone, influence product quality in obtained pulverized limestone in the prior art.
In order to achieve the above objects and other related objects, the utility model provides a kind of calcium oxide production system, including mill
Powder machine, the air outlet of the flour mill, which is connected to below cyclone separator, the discharging opening of the cyclone separator, is provided with first
Spiral shell transports machine, and the discharging opening of the first spiral shell fortune machine is connected to elevator, and the discharging opening of the elevator is connected to finished bin；It is described
The bottom of flour mill offers mud hole, and the air inlet of the flour mill is connected with blower fan, the air outlet of the cyclone separator
It is connected to the air inlet of the blower fan.
Further, the second spiral shell fortune machine is installed below the mud hole of the flour mill.
Further, the discharging opening of the second spiral shell fortune machine is connected to slag bucket.
Further, the discharge pipe of the blower fan is provided with the lingering remnants of past customs pipe towards atmospheric environment.
Further, the air outlet of the lingering remnants of past customs pipe is connected with cloth bag separator.
Further, the charging aperture of the flour mill is provided with oscillating feeder.
Further, the flour mill is YGM190 high pressure pulverizers.
Further, the cyclone separator is two, and the air outlet of the flour mill is connected in parallel to cyclone separator
Air inlet.
Further, the aperture of the mud hole of the milling motor spindle is 100-110mm.
Further, the elevator is bucket elevator.
As described above, calcium oxide production system of the present utility model, has the advantages that：Equipment of the present utility model
Arrangement, large-block material is continually fed into flour mill through oscillating feeder equal and quantitative and is ground, after grinding
Calcium lime powder rises with fan airflow, is classified, accorded with through the analysis machine (being located at the upper end inside flour mill) inside flour mill
Powder for closing fineness enters in willy-willy collector with air-flow through pipeline, is separated and collected, then through going out cyclone separator bottom
Discharge, i.e. quick lime powder.Air-flow sucks air blower by cyclone separator upper end backwind tube, and whole air flow system is circulation,
And it is that, in negative pressure state flowing, unnecessary gas imports in sack cleaner, the calcium lime powder in residual air is collected,
Residual air is discharged after being cleaned, while making the pressure of whole system maintain balance.
The flour mill course of work is to drive central axis by reductor, and the upper end of axle is connected to fill on plum blossom frame, frame
There is Burnisher apparatus and form swing pivot.Burnisher apparatus is turned round not only about central shaft, is also about bull ring revolution, grinding roller is in itself
The rotation because of rubbing action.Plum blossom frame lower end is equipped with perching knife system, and its position is in grinding roller lower end, and perching knife turns over journey together with grinding roller
It is middle that material is thrown between feeding grinding roller bull ring, form padding layer, the bed of material is rotated by grinding roller to be produced outside centrifugal force and (squeeze
Pressure) by material grinding, powder purpose processed is reached therefrom.After grinding roller and bull ring reach certain abrasion, adjustment high pressure spring is long
Degree, keeps constant grinding pressure between grinding roller and bull ring, so as to ensure the product yield and fineness of stabilization.
The analysis machine of flour mill inner upper end drives the blade on rotating disk to rotate by buncher, and formation divides powder
Level effect.The speed of blade rotational speed is adjusted by the sub- granule size of finished powder.When the finer grain powder period of the day from 11 p.m. to 1 a.m to be obtained, then carry
High blade rotational speed, makes blade contact increase with powder, undesirable set of powder is thrown to outer wall by blade, and flow shedding, slightly
Powder is refaced because the effect of gravity falls into mill room, and qualified finished powder sucks willy-willy collector by blade with air-flow
Interior, after air-flow is separated with powder, powder is collected.
Milling motor spindle opens up mud hole, and the large granular materials majority for being deposited in milling motor spindle is insufficiently burnt lime
Stone, this kind of material is gradually excluded by the mud hole, is not returned between grinding roller and bull ring and is crushed again, effectively reduces lime stone
The mixed volume of powder, improves the mass content of the calcium oxide in fine powder product.When in the lime burnt till contain a small amount of raw burn material and mistake
In the presence of imitation frosted glass, mass fraction >=91% of calcium lime powder can also be made using the utility model, outward appearance is white powder, is as good as
Thing, does not lump, and hand pinches not agglomerating, and color and luster is homogeneous, and granularity is less than mass fraction≤1% of the material of 80 mesh, and the uniformity is (with CaO
Calculated)≤1%, obtained fine powder particle diameter typically can reach 400 mesh.The utility model can be less desirable by source
Quick lime, up to product quality requirement, is unlikely to influence product quality because source quality is not good, plays good sieve after processing
It is elected to be use.
