Background technology
Medium-speed pulverizer is widely used in thermal power plant, and raw coal is squeezed between the grinding roller and mill bowl of medium-speed pulverizer
Broken and grinding is crushed, the coal dust for meeting boiler combustion is eventually become.In order to reach this purpose, it is necessary to apply sufficiently large to grinding roller
Pressure, because the pressure ratio of required application is larger, thus common loading device use hydraulic loaded mode.Hydraulic loaded side
The shortcoming of formula is that hydraulic system is more complicated, hydraulic station will often in working condition, the power of loading be substantially it is constant, will not
The adjust automatically with the change of inlet amount.
The content of the invention
It is an object of the invention to provide a kind of spring charging device, make its structure simple compared with hydraulic loading device and work
Shi Wuxu additionaling powers, at the same can realize loading force can with the change of inlet amount adjust automatically.
To reach above-mentioned purpose, the technical scheme is that a kind of spring charging device is provided, including load bar, fixation
Plate, fixing bolt, fixing nut, spring spool, end cap, locking nut, loading nut, disk spring group, sealing ring, hydraulic pressure
Cylinder, hand oil pump and spanner, it is characterised in that：Loading force that the disk spring group is produced after being compressed and disk spring group
Decrement is directly proportional, and is delivered to raw coal attrition crushing by load bar on grinding roller, adds when raw coal inlet amount changes
Power energy adjust automatically is carried, the position of load bar is screwed in while loading nut can be adjusted by hand oil pump and hydraulic cylinder and then changes
Become the initial compression amount of disk spring group to set original upload power, the reading that the big I of original upload power passes through hand oil pump
Number and the convenient determination of hydraulic pressure cylinder area.
A kind of spring charging device structure chart that Fig. 1 provides for the present invention, loading device is fixed to by fixed plate 2 and needed
On the apparatus body to be loaded, spring spool 5 is fixed in fixed plate 2 by fixing bolt 3 and fixing nut 4, passes through regulation
The position of fixing nut 4 can adjust the relative position of spring spool 5 and fixed plate 2.End cap 6 is arranged on spring spool 5, plus
The right-hand member for carrying bar 1 is threaded, and loading nut 8 is screwed in the right-hand member of load bar 1, makes the disk spring group 9 being enclosed on load bar 1
In compressive state.The position of regulation loading nut 8 can change in spring spool 5 decrement of butterfly spring group 9 and then change
Become the original upload power of spring charging device.Locking nut 7 is used to prevent loading nut 8 from releasing, and sealing ring 10 is placed in fixed plate 2
Between spring spool 5, dust leakage in equipment can be prevented to outside equipment.Sealing ring 11 is placed in load bar 1 and spring spool 5
Between, prevent the dust in equipment from entering in spring spool 5.
Instant invention overcomes defect and deficiency present in the loading device using hydraulic loaded mode, loading can be realized
Power can with the change of inlet amount adjust automatically, it is simple in construction, it is easy to operate.

Embodiment
To become apparent the present invention, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below：
First according to grinding roller 20 by the crushing grinding of raw coal 21 into qualified coal dust when required extruding force, the suitable dish of selection
Groups of springs 9, makes the maximum working load and minimum workload of disk spring group 9 meet the use requirement of grinding roller 20.With reference to figure
1, it is first according to Fig. 1 and assembles spring charging device, because the loading force of the generation of disk spring group 9 is very big, so needs to borrow
Hydraulic cylinder 12 is helped to be tightened nut 8 is loaded, hydraulic cylinder 12 is loop configuration, and loading nut is provided with 8 uniform driving holes.Twist
When tight, first its hydraulic cylinder 12 is enclosed on the outside of loading nut 8, locking nut 7 is then screwed on, then by hand oil pump 13 and hydraulic cylinder
12 connect, and pressing hand oil pump 13 makes hydraulic cylinder 12 axially elongated, and load bar 1 also moves right therewith, disk spring quilt
Compression.3 poke rods 17 are laid with spanner 16, after hydraulic cylinder 12 is elongated to certain length, dialling on spanner 16 are utilized
Lever 17 is loaded in the driving hole 14 on nut 8 through the insertion of arcuate socket 15 on locking nut 7, and rotating loading nut 8 makes it
Compress end cap 6.The power that hydraulic cylinder 12 applies can be multiplied acquisition by the area of hydraulic cylinder with manometric numerical value on hand oil pump, when
The value be equal to spring charging device needed for original upload power when, you can will loading nut 8 tighten after, pull down hydraulic cylinder 12, then
Locking nut 7 is tightened, spring charging device assembling terminates.
With reference to Fig. 5, the spring charging device assembled is fixed on medium-speed pulverizer body by fixed plate 2.Coal-grinding
When machine works, mill bowl 22 rotates and drives grinding roller 20 to rotate together, and raw coal 21 is then brought into the seam between mill bowl 22 and grinding roller 20
In gap.Now load bar 1 is in the state that holds out against with grinding roller 20, and the power that disk spring group 9 is produced is delivered to grinding roller by load bar 1
On 20, it is further transferred on the raw coal between grinding roller 20 and mill bowl 22, is extruded raw coal and crushes and grind to form coal dust.Due to
The loading force that disk spring group 9 is produced after being compressed is directly proportional to the decrement of disk spring group, so when grinding roller 20 and mill bowl
Loading force energy adjust automatically when raw coal amount between 22 changes.
