Abstract
The present invention relates to a method for preparing filtration aid by utilizing diatomaceous earth. It is characterized by that the raw earth can be directly broken and dried, and can be fed into production system of filtration aid so as to make the production from raw earth to filtration aid product implement matched systematization. Said method is simple, and its application range is extensive.
Description
Technical field:
The present invention relates to a kind of is the method for feedstock production filter aid with diatomite.
Background technology:
At present be: at first use a large amount of soils and personnel at production filter aid off-site in the method for utilizing diatomite to prepare filter aid, diatomite original soil is become moisture about 15% dry body, dried piece through air dry (sun-dried mud brick) or artificial drying (soil block), through being ground into required dry powder, send into the filter aid production line of plant area again.The preliminary preparation of this filter aid is all carried out in the open, its shortcoming is: the occupation of land amount is big, recruitment is many, and be subjected to climatic effect, not only can not make rainy season influences output, diatomite original soil also is subjected to washing away of rainwater and soaks, loss big (losing about 20% approximately), examining of land occupation in addition, the applications of recruitment etc. bother very much.The more important thing is and to form unified production system with the filter aid production line.Increase management difficulty, can not guarantee the quality and the output of raw material.
Technology contents:
For solve existing diatomite produce the filter aid process in shortcoming, the invention provides and a kind ofly realize that original soil is directly broken, drying enters the filter aid production system, make original soil prepare the method for filter aid to the diatomite of filter aid production corollary systemization.
Step of the present invention is as follows:
A, at first diatomite original soil is packed into crusher in crushing becomes small clod;
B, small clod are sent into brokenly mixed doubles pipe feeding machine by conveyer belt, add cosolvent in course of conveying, broken once more stirring the in broken mixed doubles pipe feeding machine;
C, again by in the two-tube feeder feeding strong drying machine, and broken once more;
D, dried material enter cyclone separator and carry out the separation of gas material by one-level grader, secondary grader, three grades of graders, and gas purifies emptying through deduster;
E, the dry mash that separates with deduster through cyclone separator are sent into rotary kiln baking by conveying worm and are entered the filter aid production system.
The present invention's dry material in drying machine separates by the one-level grader, by the secondary classification, qualified material enters cyclone separator to the material that classification goes out again, and defective material enters No. three the further classifications of grader again, qualified material enters cyclone separator, and defective material is discharged; Defective material is still in the drying machine fragmentation, till being separated in one-level grader classification process.
Cyclone separator of the present invention and deduster are a cover at least.
Advantage of the present invention is:
1, the present invention has realized that directly fragmentation, drying enter the filter aid production system, make original soil to filter aid production corollary systemization original soil.
2, of the present invention coming into operation calculated by producing 5000 tons of filter aids per year, can save to take up an area of and reduce artificial 80-100 name more than 20 mu.Reduce resource loss more than 15%.
3, the present invention has reduced the pollution to personnel and environment of dust and noise because of removing the dry body crushing process from.
4, the present invention is because of avoiding expenditure, but 1 ton of product synergy more than 100 yuan, 10,000 tons of year products, but 1,000,000 yuan of synergy.
5, the present invention has changed the method for adding cosolvent in dry mash, adds cosolvent in original soil, makes it utilize original soil moisture content to be dissolved in the original soil, guarantees the filter aid product quality.
6, the device that need adjust of the present invention is adjustable, easy to operate, and the scope of application is extensive.
The specific embodiment:
Concrete steps of the present invention are as follows:
A, diatomite original soil is packed into disintegrating machine at first, original soil be broken under disintegrating machine zigzag tooth brute force is knocked and cut＜small clod about 3cm.
B, small clod fall within and send into brokenly mixed doubles pipe feeding machine on the conveyer belt, in course of conveying, quantitatively add cosolvent by the single-tube quantitative feeding machine, send into brokenly compound in the mixed doubles pipe feeding machine, broken once more the stirring, its soil, solvent are fully mixed, utilize the moisture in the original soil that cosolvent is dissolved in the soil simultaneously.
C, again by in the two-tube feeder feeding strong drying machine, enter the rotation grating disk of the compound high speed rotating in machine in the strong drying machine and fixedly the brute force of crushing tooth pulverize under the bump, be ground into once more＜particle of the granularity of 0.1mm.
D, dried material enter cyclone separator and carry out the separation of gas material by one-level grader, secondary grader, three grades of graders, and gas purifies emptying through deduster;
E, the dry mash that separates with deduster through cyclone separator are sent into rotary kiln baking by conveying worm and are entered the filter aid production system.
The present invention's dry material in drying machine separates by the one-level grader, by the secondary classification, qualified material enters cyclone separator to the material that classification goes out again, and defective material enters No. three the further classifications of grader again, qualified material enters cyclone separator, and defective material is discharged; Defective material is still in the drying machine fragmentation, till being separated in one-level grader classification process.
Rotary kiln produces 300 ℃ of tail gas are heated into 500 ℃ through gas burner thermal current, and the multiple action of the eddy flow that the one-level grader produces in the machine forms the material stream that suspends and rotate down, material stream is finished heat exchange in last current downflow and rotation, make particle moisture≤5%, particle separates the granularity that is fit to and is sent into classification again in secondary grader, the three grades of graders by blower fan in adjustable one-level grader.The particle that is not separated is still pulverized till being separated repeatedly interior.
Being inhaled into cyclone separator through the particle (dry powder) of secondary split pole machine and three grades of grader classifications carries out the gas material and separates, gas is through deduster udst separation emptying, sends into rotary kiln baking by conveying worm and enters the filter aid production system through separating the dry mash that separates with deduster.
Material of the present invention enters behind the strong drying machine all in the negative pressure current downflow.
System is tunable arrangement except that strong drying machine and blower fan, with the production of the different size type product that adapts to different cultivars.
According to the requirement of producing, cyclone separator and deduster are a cover at least, when requirement is little, only need a cover cyclone separator and a deduster, and amount is big if desired, can according to circumstances need two covers or above cyclone separator and the deduster of two covers.
