Preparation facilities, including two lime bins, four sets of blanking powder feeder units.Pulverized limestone is transported by tank car to scene, empty by compression
Gas squeezes into pulverized limestone in feed bin, and blanking device is stopped by lime white tank liquid automatic control, low liquid level operation, high liquid level.
There are problems mainly to have lime powder particles thinner, good fluidity, can flow into stone by helixes feed equipment under shutdown status
In grey cream tank, and milk of lime process for preparation is exothermic reaction, and moisture ascends into lime bin, is tied after easily leading to pulverized limestone dampness
Block causes blanking device to block, and lime milk concentration is unstable in lime white tank, brings difficulty to the control of sour waste water neutralisation treatment,
And then influence sour waste water neutralisation treatment effect.
Summary of the invention
The utility model provides a kind of lime blanking device, prevents pulverized limestone from flowing into stone by powder supply machine under shutdown status
Grey cream tank, while avoiding moisture rising causes pulverized limestone in feed bin to agglomerate after making moist, and causes blanking device to block, causes lime
The unstable problem of lime milk concentration in newborn tank, it is ensured that the stable operation of device for preparing lime milk improves sour waste water neutralisation treatment
Effect.
The technical solution adopted in the utility model is:
A kind of lime blanking device, including two sets of blanking devices and star-shaped pocket feeder, lime bin lower part connect under two sets
Expect device, every set blanking device includes feed bin, cloth bag, star-shaped pocket feeder, screw feeder, cyclone, lime white tank；The star
Shape dispenser is rectangular parallelepiped structure, and it is agitating shaft on central axis, agitating shaft is set radially outside that inside, which is equipped with star blender,
There are eight agitating paddles, agitating paddle is uniformly distributed along agitating shaft surrounding.
In above-mentioned apparatus, the star-shaped pocket feeder is connect by sprocket wheel with variable-frequency motor, is controlled by adjusting electric machine frequency
The revolving speed of star-shaped pocket feeder processed makes star-like feeder discharge quantity match with screw feeder feeding coal.
In above-mentioned apparatus, the star-shaped pocket feeder is mounted on above screw feeder, by Frequency Converter Control star-shaped pocket feeder
Revolving speed；When milk of lime stops preparing, by the contact of star-shaped pocket feeder cutting pulverized limestone and lower section moisture.That is: star-shaped pocket feeder
When operation, by variable frequency adjustment, the quantitative lower ash of pulverized limestone is realized.And lime white tank high liquid level need star-shaped pocket feeder and
When screw feeder stops working, star-shaped pocket feeder is capable of the interface channel of closed lime cream tank and lime bin, avoids lime
Steam in newborn tank enters lime bin.
The utility model increases star-shaped pocket feeder, is changed to two-stage blanking by level-one blanking, pulverized limestone enters star-shaped pocket feeder
Afterwards, it is rotated by star-shaped pocket feeder, pulverized limestone is equably sent into screw feeder, then sent to cyclone by screw feeder,
Enter lime white tank after mixing in cyclone with water.It can guarantee that pulverized limestone is fed uniform, metering essence after increasing star-shaped pocket feeder
Really, dreg discharge amount is big, is not easy blocking, two-stage blanking simultaneously, is not in large quantities of lime leakage and can effectively completely cut off milk of lime
Moisture ascends into lime bin in tank, prevents pulverized limestone dampness agglomeration, guarantees the normal operation of device for preparing lime milk.
Lime blanking device provided by the utility model, bring the utility model has the advantages that
(1) the utility model is completely separated lime bin with milk of lime storage pool, prevents lime leakage problem, and lead to
The use for originally unloading grey blanking device is crossed, is measured more accurate.
(2) compared with traditional lime blanking device, the utility model dreg discharge amount is big, is not easy blocking, measures accurately, and
And two-stage blanking device is used, it is not in large quantities of lime leakage.
(3) former lime preparation facilities faults frequent needs operations staff to tap funnel position above gate valve daily, under help
Ash monthly needs to empty feed bin inspection cleaning feed bin agglomeration, and after the utility model, pulverized limestone blanking is normal, it is only necessary to every half a year
It empties feed bin to be checked, and the lime milk concentration prepared is uniform.
(4) the utility model can effectively completely cut off moisture in lime white tank and ascend into lime bin, prevent pulverized limestone from making moist
Agglomeration, guarantees the normal operation of device for preparing lime milk.
The utility model is described further with reference to the accompanying drawings and examples.
Detailed description of the invention
