Description
Technical field
The present invention relates to the grinding roller pressure adjustable hot air circulation roller mill that a kind of back-blowing seals
Device.
Background technology
Vertical roll grinder is called for short Vertical Mill, a kind of for cement slurry, clinker, slag and coal
Ground-slag mill processing, has simple in construction, a feature that manufacturing cost and use cost is low.Including body,
Millstone device and actuating device, be provided with between body and millstone device and determine determining of the centre of gyration
Core structure, the bottom of millstone device is fixedly installed circular guideway, and millstone device is led by revolution
Rail is rotatable to be supported on body, and millstone device is connected with drive.Owing to transmission fills
Putting weight and the contour axial load of pressure of milling being not subject to mill, therefore actuating device can use
General reductor, thus there is structure and configure compact, the advantage of reliable operation, can shorten and stop mill
Time, reduce the operation and maintenance cost of equipment.
Vertical roll grinder operation principle: motor is rotated by reductor band movable grinding disc, material
Falling in mill central authorities from charging aperture through lock feeding device, hot blast enters in mill from air inlet simultaneously.
Along with mill rotates, material, under centrifugal action, moves to mill edge, on mill
Rolled by grinding roller during cannelure and pulverize, crushing rear material at mill edge by vane high speed gas
Stream takes up, and bulky grain falls directly on mill grinding again, and in air-flow, material separates through top
During device, under rotor effect, coarse powder falls mill grinding again, qualified fine powder from cone bucket
Trip out mill with air-flow one, collected by dust arrester installation, be product, containing moisture material with
Thermal current contact process is oven-dried, by regulation hot blast temperature, different humidity material can be met
Requirement, reaches required product moisture.By adjusting separator, needed for can reach different product
Fineness degree.
Roller mill after carrying out material grinding, need heat blow in powder selection device, and different
The different material of fineness degree, needs different size of hot blast to blow process to complete this, if wind-force
Excessive, the defective material that some are thicker can be blown in powder selection device, if wind-force is too small, nothing
Qualified material is blown in powder selection device by method.
According to different materials and the fineness degree of required product, need the oil pressure driving grinding roller
Oil pressure in cylinder is adjusted, thus adjusts the pressure between grinding roller and mill, at present, one
Oil pressure in the oil hydraulic cylinder of bench roller grinding machine cannot be carried out regulation, causes a bench roller grinding machine to be merely able to powder
One the serial material in end.
Simultaneously as the inwall rotating cage top outer and roller mill of powder selection device exists all the time
Certain gap, material can enter hot-blast outlet by this gap under the drive of hot blast, thus
That has avoided rotation cage selects powder step, and then can affect the quality selecting powder.
After material is ground by roller mill, the product needed obtained is absorbed by dust-precipitator, receives
After dirt device absorbs, by the hot blast discharged in roller mill also has bigger heat, if this heat is straight
Run in and be put in air, not only waste a part of heat energy, the most also can atmosphere pollution, time long
Between discharge affect the environment of periphery.
Summary of the invention
For the problems referred to above, the grinding roller pressure that the invention provides the sealing of a kind of back-blowing is adjustable
Hot air circulation roll mill apparatus, regulate air inlet at any time according to the different product of different thicknesses degree
Wind speed, in order to more effectively qualified material is blown in powder selection device, by rotate cage with
Back-blowing structure is set on the gap of roller mill inwall, thus prevents material from being tapped into by this direct clearance
Entering hot-blast outlet discharging, be effectively increased rotation cage selects opaque amount, by receiving through dust-precipitator
Hot blast after dirt is circulated utilization, thus improves heat utilization rate, prevents heat energy from producing environment
Raw adverse influence.
