Background technology
Existing material grinding equipment, as ball mill, Raymond mill, small-sized Vertical Mill etc., mill output is low, it is high to consume energy, feed separation difficulty.And containing magazins' layout difficulty in material, and the impurity that some hardness is higher, as heavy pebble coal, pyrite, iron block etc., be easy to damage grinding roller, bull ring, grinding machine is forced to stop production reparation, and impact is produced and is used, and brings the extra costs such as maintenance, maintenance to user.
Application number is 201320220884.2 disclose a kind of wear-resisting vertical coal grinding machine, and its main technical scheme is: " by material is joined bull ring central authorities, bull ring is by power source driven rotary, and grinding roller and material friction, passive rotation, rolls material.Material after milling brushes through the warm braw of air inlet, and the material of milling, through grinding machine top sorting machine, is discharged by discharging opening, and the larger material particles of the proportion that cannot brush is discharged by the slag-drip opening of bottom." program exists and following to determine: 1), material joins bull ring from charging aperture; easily occur local accumulation, uneven; be unfavorable for the friction of grinding roller and material; 2), the sphere of action of grinding roller is limited; the material outside grinding roller is difficult to be rolled, 3), the solid accumulation of local easily causes air inlet and slag-drip opening to block.
Utility model content
The utility model mainly solves technical problem existing in prior art, thus provides a kind of novel vertical coal mill rolling evenly, prevent solid accumulation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The novel vertical coal mill that the utility model provides, comprise base, charging aperture, discharging opening, collecting bin and storehouse of milling, described storehouse of milling is provided with air inlet and slag-drip opening, its inside is provided with bull ring, described base is also fixed with power source, described power source rotates for driving described bull ring, also sorting machine is provided with in described collecting bin, it also comprises the first holder, second holder, two bearing blocks, fixed axis, cylinder and multiple grinding roller, described first, to mill described in second holder is separately fixed at the both sides, bottom in storehouse, two described bearing blocks are corresponding is respectively fixed on described first, on second holder, and its inside is all provided with bearing, described fixed axis is located between two described bearing blocks, and its one end also connects with described cylinders, wherein, described cylinder moves left and right for controlling described fixed axis.
Further, the quantity of described grinding roller is four, and equidistantly distributes along on the length direction of described fixed axis.
Further, the periphery of described grinding roller is also provided with multiple flange, and the cross sectional shape of each described flange is triangle.
Further, the one end away from described cylinder on described fixed axis is also provided with a limiting plate.
Further, described bearing is linear bearing.
The beneficial effects of the utility model are: promote fixed axis by cylinder and move left and right, multiple grinding roller is driven to move left and right, material can be stirred while grinding roller carries out rolling material, prevent solid accumulation, also the material outside grinding roller is made to be rolled, improve and roll efficiency, and material is struck evenly and makes air inlet and slag-drip opening decrease blocked phenomenon.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of novel vertical coal mill of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, novel vertical coal mill of the present utility model, comprise base 1, charging aperture 2, discharging opening 3, collecting bin 4 and storehouse 5 of milling, storehouse 5 of milling is provided with air inlet 6 and slag-drip opening 8, its inside is provided with bull ring 7, base 5 is also fixed with power source, power source rotates for driving bull ring 7, sorting machine 17 is also provided with in collecting bin 4, it also comprises the first holder 9, second holder 10, two bearing blocks 11, fixed axis 12, cylinder 13 and multiple grinding roller 14, first, second holder (9, 10) both sides, bottom in storehouse 5 of milling are separately fixed at, two bearing blocks 11 are corresponding is respectively fixed on first, second holder (9, 10) on, and its inside is all provided with bearing, this bearing is linear bearing, reduce sliding-frictional resistance.Fixed axis 12 is located between two bearing blocks 11, and its one end is also connected with cylinder 13.Wherein, cylinder 13 moves left and right for controlling fixed axis 12.The utility model promotes fixed axis 9 by cylinder 13 and moves left and right, multiple grinding roller 14 is driven to move left and right, material can be stirred while grinding roller 14 carries out rolling material, prevent solid accumulation, also the material outside grinding roller 14 is made to be rolled, improve and roll efficiency, and material is struck evenly and makes air inlet 6 and slag-drip opening 8 decrease blocked phenomenon.
