Description
Technical field
The utility model belongs to material grinding equipment; Be particularly related to a kind of center pressing type tube roller abrasive dust mill apparatus.
Background technology
At present, be used for the milling equipment of industries such as metallurgy, iron and steel, building materials and electric power, adopt tube roller abrasive material bed extrusion grinding equipment usually, be divided into the milling equipment of exerting pressure of guide tracked exert pressure milling equipment and torsion posture by the grinding mode of exerting pressure.The structure of the wherein guide tracked milling equipment of exerting pressure comprises rotating cylinder, bracing or strutting arrangement, grinding roller, charging aperture and the discharging opening of drive mechanism; Be loaded on sealed at both ends rotating cylinder on the bracing or strutting arrangement by drive mechanism, one end top of rotating cylinder is provided with inlet, other end bottom is provided with outlet, the rotating cylinder inner surface is provided with lining and abrasion-proof backing block, be provided with the bearing support of pressurization grinding roller in the carrying cylinder at the rotating cylinder two ends, and on bearing support, be provided with for the radially upper and lower mobile guide rail of pressurization grinding roller.Though, the structure of the guide tracked milling equipment of exerting pressure is comparatively simple, in light weight, but in the grinding process of complexity, that is to say that for acting on the material bed direction of making a concerted effort and the size that act on pressure roller are difficult to determine, also can produce additional wear to guide rail, in the theory design, bring many uncertain factors; And the milling equipment of exerting pressure of torsion posture, its structure is comparatively complicated, and big and heave, floor space are big, give and make, install, safeguard and bring difficulty.Simultaneously since when adopting the torsion posture to exert pressure mode the slide shoe bearing of rotating cylinder be supported for asymmetric layout, thereby make slide shoe bearing bracing or strutting arrangement unbalance stress, its result produces vibration.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and a kind of center pressing type tube roller abrasive dust mill apparatus is provided; This grinding device had both overcome the complex structure of the milling equipment of exerting pressure of torsion posture, big and heave, be difficult to make, the defectives such as unconcentrated and additional wear of making a concerted effort of the guide tracked milling equipment of exerting pressure have been overcome again, make device for exerting simple and practical, Ji possesses active adjustment ability and easy to adjust again because the slide shoe bearing bracing or strutting arrangement cooperating of center device for exerting and symmetric arrangement, make the plant equipment stress form analyze in theory simply, simple on the structure, overall operation is reliable.
The purpose of this utility model is to adopt following technical scheme to realize: described a kind of center pressing type tube roller abrasive dust mill apparatus comprises rotating cylinder, bracing or strutting arrangement, grinding roller, charging aperture and discharging opening by drive mechanism; It is characterized in that: rotating cylinder is supported by the slidnig track type bracing or strutting arrangement; Be symmetrical arranged two memorial archways of exerting pressure on the outer basis of the corresponding rotating cylinder in two axial ends position of grinding roller axle, at the two top symmetry installings two of the exerting pressure memorial archway oil cylinder of exerting pressure, the two two-piston bar external parts of exerting pressure oil cylinder go out the outer two axial ends of rotating cylinder with the grinding roller shaft extension respectively and are connected, and two other ends of exerting pressure oil cylinder are hinged on two respectively and exert pressure on the memorial archway; And simplified vertical centre of revolution and the vertical centre phase line that is loaded on the grinding roller in the cylindrical shell are coincided, form center pressing type tube roller mill.
Described slidnig track type bracing or strutting arrangement is made up of slide shoe bearing and slide shoe bearing support, at slide shoe bearing support upper support slide shoe bearing.
Described two oil cylinders of exerting pressure all adopt the servo-hydraulic oil cylinder; Two oil cylinders of exerting pressure drive the vertically upper and lower motion of grinding roller in the two memorial archway inter-syncs of exerting pressure respectively.So, exert pressure in the memorial archway because the two ends of grinding roller axle are installed in two, make grinding roller limit motion in the horizontal direction in movement in vertical direction, therefore, the equipment that makes operates steadily.
In the liquid oil return line of described each oil cylinder of exerting pressure, be provided with the hydraulic leather bag type accumulator that absorbs vibration and overvoltage.
Principle of the present utility model and operation are described below:
Because the grinding roller in the utility model vertically is synchronized with the movement up and down, solved the problem of " just not low " in the material bed grinding process with regard to height in the memorial archway of exerting pressure; When entering under the mill inner press roll, material formed uniform material bed, the both sides servo-cylinder is simultaneously by the synchronism of an oil pump feed with the assurance oil cylinder, pressure roller is under the effect of waiing upon the clothes oil cylinder, guaranteed the synchronism of both sides hydraulic jack actions, when running into the bigger lump material of particle, lump material is higher than the material bed, this moment pressure roller in depressing process, at first touch the lump material that is higher than average material bed thickness and and then with its pulverizing, it is suitable with the material bed height that pulverized lump material becomes at this moment, because of short transverse changes, so can be to its periphery extruding diffusion at material bed thickness direction, and peripheral other granular materials that are higher than average material bed height are also done identical variation, material on the whole grinding track width so moves in circles, so formed material bed extruding grinding process, weakened because the vibrations that the low injustice of the material height of bed is brought operate steadily equipment.
Combine the above technical scheme of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, simple in structure, both overcome the torsion posture exert pressure mode shape big body weight, implement the problem that is difficult for, overcome the guide tracked problem such as additional wear of making a concerted effort not concentrate again, make device for exerting simple, possess the active adjustment ability and reconcile conveniently, equipment operates steadily; And, also because with symmetrically arranged slidnig track type bracing or strutting arrangement upper support rotating cylinder, the grinding roller in rotating cylinder is the employing center mode of exerting pressure again, makes both active forces cooperate consistent, make that mechanically stressed form analysis is simple, overall operation is reliable and use characteristics such as very convenient.
Combine the above technical scheme of being taked, realize the purpose of this utility model.
