Blower fan special consideration: blower fan is high-speed rotation equipment, can produce more strong vibration, is postponed using high-order cloth,
There are two problems: the stability 1. vibrating the beam column to building brings adverse effect, especially high-order cloth postpones, to building
Beam column produces bigger destructive power.2. import and export air main 7 bore of blower fan is big, diameter of up to 1.2m, and the vibration of blower fan passes to
After air main 7, cause larger rocking to piping, piping stability reduces.The seam of pipeline and blower fan is due to Long-term Vibration
It is also easy to produce tear.For solving the above problems, take following measures: 1. blower fan adopts spring shock absorption basis, fully absorb blower fan and pass
Pass the vibration on basis, eliminate the impact vibrated to flooring of taking root, beam column of blower fan.2. blower fan is imported and exported and is adopted flexible joint, every
The vibration of exhausted blower fan is to the transmission of air main 7.Take out dirt blower fan 5 and a sorting blower fan 6 is all subtracted using spring for described No. one
Shake basis, and take out dirt blower fan and sort the import and export of blower fan all using flexible joint.
Preferably, can be in two sets of agstone preparation system (not shown)s of same local arrangement, this spline structure
Compacter, effect is more excellent.It is interpreted as in two sets of agstone preparation systems of same local arrangement: set accordingly in same layer

Tool Room, control room and mcc room.
As shown in figure 5, a kind of agstone preparation system technological process, it comprises the steps:
S1: limestone block enters pan feeding surge bunker 2 by pan feeding elephant trunk；
S2: the limestone block in pan feeding surge bunker 2 enters in column mill 1 and is milled；
S3: the agstone after milling is promoted to a waterfall current classifier 9, a sorting blower fan 6 by bucket elevator 10
Blast high-pressure blast to a waterfall current classifier 9 and carry out stock grading；
S4: after classification, qualified agstone and air mixture are admitted to a cyclone separator 11, in a whirlwind
In the presence of separator 11, qualified agstone is captured, and sends into limestone powder bin 16；Underproof Calx after classification
Stone powder returns pan feeding surge bunker 2 by returning charge elephant trunk 4, again goes into column mill 1 and crushes, until becoming qualified product.
Preferably, the air that in described step s4, cyclone separator is discharged is taken out dirt blower fan and is delivered to cleaner unit, at purification
Reason heel row is to air；The agstone that cleaner unit stays sends pan feeding surge bunker 2 back to by returning charge elephant trunk 4.
The present invention at least employs following key technology, and achieves corresponding technique effect.
(1) adopt elephant trunk technology, save equipment link
All replace drag conveyor in grinding machine pan feeding link, sorting returning charge link and finished powder warehouse-in link using elephant trunk,
Elephant trunk adopts wear-resistant material, and inclination angle is more than the natural packing angle of agstone.And on pan feeding elephant trunk configuring pipes tramp iron separator, clearly
Except the irony in material, it is to avoid damage grinding machine.The use of elephant trunk, saves 3 sets of drag conveyors and significantly reduces occupation of land space.
(2) space lamination placement technique, saves and takes up an area
Equipment is arranged, the utilization ratio of spatial altitude is relatively low by conventional arrangement along the horizontal plane.And space lamination placement technique
Then focus on the space utilization of short transverse.Using the space of short transverse, using connecting line, realize the concentration cloth of equipment
Put, profit reduces plane and takes up an area.Such as sorting blower fan in preparation system, take out dirt blower fan, conventional arrangement distribution is more scattered, takes up an area
Greatly；Using lamination placement technique, then can reduce plane and take up an area two kinds of blower fan centralized arrangement together.
(3) flat bed nested arrangement technology, saves and takes up an area
Flat bed Nesting Technique, as the term suggests, its theory is: on the premise of meeting Regulations, by equipment
Arranged crosswise, saves plane and takes up an area.Below, in conventional arrangement taking the separation system of pulverized coal preparation system as a example, cleaner unit and separation
Device is in that " one " font is arranged, layout is more loose, and after nested arrangement technology, separator and cleaner unit are in that " t " type is arranged, cloth
Office is more compact.
(4) employing side storehouse technology, this technology can make in preparation system the capacity utilization of conventional powder cabin improve to 95% with
On, thus reducing equipment volume, save equipment investment and space expenses further
Square storehouse is directed to warehouse entrance, stage casing and outlet section and is all processed, and the effect being obtained is:
There is the function of automatic filling, in limited space, so that square storage capacity is maximized, increase the storage capacity in storehouse；
Realize bulk flow discharging, make in square storehouse, to occur without dead angle and mouse hole (mouse hole: in limestone powder bin discharging
When, the agstone easily being formed around discharge port draws off, and the agstone of surrounding is motionless, finally will be formed in storehouse around
Discharge port occur a cylindric hole) phenomenon it is ensured that in the storehouse in storage limestone meet engineering production storage time requirement.
Solve the Dead Core Problems in square storehouse, make agstone at square storehouse Nei Buliu dead angle, and prevent limestone powder
Hardened arch camber in square storehouse.
Conventional arrangement (Yunnan power plant of patrol and inspection office) and high-order arrangement (agstone preparation system arrangement knot of the present invention
Structure) (Sichuan Baima Power Plant 300mw) contrast
Primary operating parameter contrast table:
As can be seen from the table, exerted oneself more greatly using the pulverized coal preparation system that the high-order cloth of high-order arrangement postpones, pipe resistance is less.
Indicators of overall performance and the comparison of domestic and international similar technique
Indicators of overall performance compares
Impetus to society, economic development and scientific and technological progress
Meaning of the present invention is:
(1) significantly reduce initial cost and the operating cost of agstone preparation system itself
(2), due to the occupation of land of preparation system is greatly reduced, it is prerequisite to be that preparation system provides near boiler room region arrangement
Condition.So significantly shorten the fed distance that agstone adds system (from preparation station to burner hearth entrance), not only reduce and add
System initial cost, also can be greatly reduced the operation energy consumption of addition system.
(3) reduce station service power consumption rate, reduce maintenance cost, for building green, low-carbon (LC) power plant provides support.
Promotion and application prospect
Present invention application remarkable in economical benefits, has a extensive future, and economic benefit, social benefit and environmental benefit are notable,
Can will make tremendous contribution in China's wide popularization and application for construction green, low-carbon (LC) power plant.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention it is noted that all
Any modification, equivalent and improvement of being made within the spirit and principles in the present invention etc., should be included in the guarantor of the present invention
Within the scope of shield.
