Description
Technical field
The utility model relates to milling apparatus technical field, in particular to a kind of roller ring mill.
Background technique
Roller ring mill is the professional equipment of blast furnace process auxiliary material stock processing, can be provided for high smelting system
Suitable auxiliary material (such as: coal dust).
Existing coal pulverizer mainly utilize it is multiple with the close-fitting mixing roll of coal pulverizer cabinet wall to coal cinder into
Row grinding, it may be assumed that coal cinder is squeezed using the gap between gap and mixing roll between each mixing roll and coal-grinding box body
Pressure is to be made coal dust；But since the gap between each mixing roll and mixing roll and coal-grinding box body is smaller, and coal cinder
Size is larger, therefore can not store a certain amount of coal cinder, therefore in coal pulverizer work, it needs lasting coal to be added into coal pulverizer
Block, not only process is heavy, and there is also the defects of grinding efficiency difference.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of roller ring mill, purport
The problem in solving above-mentioned background technique.
The technical solution of the utility model is achieved in that a kind of roller ring mill, including grinds case and divide
Not She Yu the grinding box top and grinding bottom portion inlet port and outlet port, it is characterised in that: including be set to the grinding case
Interior grinding assembly, set on the grinding assembly two sides feeding device and be set to grinding case two sides outer wall and spaced cunning
The sliding slot of slot, the grinding case two sides shifts to install；The grinding assembly includes being set to inside the grinding case and with charging
Mouth is two mixing rolls of symmetry axis symmetrical clearance setting, and each mixing roll passes through shaft and grinds the inner wall rotation connection of case,
The storage cavity that section is " quadrant " is each formed between each mixing roll and grinding case；Each feeding device includes and each turn
The swivel becket of axis outer wall rotation connection, the outer wall of each swivel becket pass through fixed block and are fixedly connected with and storage cavity bottom end face phase
The upper flitch of adaptation, each upper flitch be fixedly connected with far from a side end face of fixed block be adapted with the sliding slot and for across
The thorn material block of material, the thorn material block are fixedly connected with far from the side of upper flitch and play material block by Driven by Hydraulic Cylinder；It is described
Grinding case is equipped with the inner cavity penetrated for each thorn material block.
It is preferred that are as follows: thorn material block is set as tip close to one end of feed inlet and to be equipped with multiple thorns material on the surface of tip convex
It rises.
It is preferred that are as follows: it is connected to inside the bottom of the inner cavity and grinding case.
It is preferred that are as follows: each upper flitch is fixedly connected with close to the top edge of mixing roll side and mutually fits with mixing roll surface radian
The arc block matched.
By using above-mentioned technical proposal: a certain amount of coal cinder can be added on feeding device before the grinding for storing up
It deposits, and a certain amount of module is added between mixing roll, when starting grinding, first pass through mixing roll to the coal cinder between mixing roll
It is ground, after when the part, coal cinder has been ground, by driving feeding device by the coal cinder of storage between mixing roll
Conveying in gap, so that the coal cinder to another part is ground, and then avoids the need for continuing that coal cinder is added into coal pulverizer, then
Simplify process, with the efficiency for improving grinding；In more detail: coal cinder can be added to grinding case by feed inlet, due to
Mixing roll is symmetrical arranged by feed inlet for symmetry axis, therefore when coal cinder is added in grinding case, coal cinder can be slided by mixing roll
To upper flitch, when storing a certain amount of coal cinder in upper flitch and between each mixing roll, driving mixing roll rotation is to it
Coal cinder in gap is ground, and after coal cinder is ground into coal dust, can drop to discharge port by the gap between mixing roll
Place is simultaneously expelled to grinding case by the discharge port, thus the process for completing grinding；Secondly, the coal cinder between mixing roll is ground
After, upper flitch (that is: upper flitch is overturn using each swivel becket as several points) and upper flitch are risen by driving hydraulic cylinder
Coal cinder in its top end surface is transported into the gap between mixing roll, thus to realize grinding to the coal cinder in upper flitch,
And then improve the efficiency of grinding；It should be understood that (one), each upper flitch overturning during, due in upper flitch
Coal cinder is more, and when upper flitch is overturn to highest point, due to the superposition between coal cinder, coal cinder falls to grinding case in order to prevent
Outside, spinosity flitch is set therefore in upper flitch, it may be assumed that the thorn flitch may pass through the coal cinder in grinding case, reach the crushing to coal cinder
Effect, not only can be improved the efficiency of grinding, and the situation for also effectively avoiding coal cinder from falling to outside grinding case occurs；(secondly),
The thorn material protrusion of one end setting of thorn material block, can further improve the puncture effect to coal cinder, and then further increase grinding
Efficiency；(thirdly), due to thorn material block after being punctured to coal cinder enter inner cavity in, part coal dust will necessarily be brought into interior
Chamber, therefore may make the part coal dust that can fall in grinding case for being connected to inside inner cavity and grinding case, and arrange by discharge port
Out；(its four), the arc block being fixedly connected in upper flitch close to the top edge of mixing roll side, can be improved the feeding of upper flitch
Efficiency avoids coal cinder from being just discharged from discharge outlet without grinding, to further increase the grinding efficiency to coal cinder.
The utility model is further arranged to: it is " isosceles that multiple rows of section is equidistantly equipped in the top end surface of the upper flitch
The abrasive material block of triangle ", the angle that angle is formed between the side and upper flitch of the abrasive material block is 60 °.
By using above-mentioned technical proposal: the purpose for the abrasive material block being arranged in upper flitch top end surface is: (one), mill
Expect that block can be when coal cinder be added to upper flitch, the module that first choice is contacted with upper flitch carries out pretreatment crushing, thus further
Improve the efficiency of grinding；(secondly), the formation of abrasive material block is set as isosceles triangle and is formed as 60 ° of angles between upper flitch
Purpose be, when upper flitch is overturn to highest point, the rate of blanking to be improved, so that the efficiency of grinding is improved, secondly, can also
The structural strength of abrasive material block is improved, to guarantee that abrasive material block crushes the pretreatment of coal cinder, and then is indirectly improved to coal cinder
Grinding efficiency.
