Abstract
The utility model discloses a grinding roller device of a vertical grinder. An annular roller body is fixed at end part of a grinding roller shaft by a bearing and the end of the grinding roller shaft is fixed by a gland; the roller body is externally provided with a circle of roller skin which is matched with a grinding disk liner for grinding materials; and the surface of the roller skin is provided with an overlaying layer. The whole grinding roller is stable and reliable with slight vibration during the operation process of the vertical grinder. The roller skin is in the shape of a tire, so that the grinding of the materials can be effectively enhanced; meanwhile due to the use of the overlaying layer at the grinding part of the roller skin, after a use cycle, an abraded part can be patch-welded by means of an overlaying mode, so that the service life of the grinding roller is prolonged effectively; and the working efficiency is increased and the cost is saved.
Description
Technical field
The utility model relates to grinding roller of vertical mill.
Background technology
At present, during grinding roller manufacturer production grinding roller of vertical mill, be at home and abroad mainly to adopt potassium steel or rich chromium cast iron monoblock cast to form.If adopt the potassium steel casting, because it wears no resistance, the life-span is shorter, and the grinding roller replacement cycle is short, and workload is very large; If adopt the rich chromium cast iron monoblock cast, use noble metal more, its price comparison is expensive, and because the conical central hole of grinding roller of wheat flour-milling is to process after heat treatment, and the rich chromium cast iron hardness after heat treatment is higher, processes very difficultly, and efficient is low.
The utility model content
Technical problem to be solved in the utility model is to realize a kind of superperformance that can guarantee grinding roller, can effectively guarantee again the grinding roller of vertical mill device of grinding roller quality.
To achieve these goals, the technical solution adopted in the utility model is: a kind of grinding roller of vertical mill device, the ring-type roll body is fixed on the shaft of grinding roller end by bearing, and this end is fixed by gland, described roll body is provided with a circle coordinates grinding material with lining board for grinding discs roller skin outward, and described roller epidermis face is provided with overlay cladding.
Described roller skin and roll body junction are provided with conical ring, and described conical ring is fixed on roll body by set bolt.
Described bearing comprises double taper roll bearing and double cylinder roller bearing, and described double taper roll bearing is positioned at outside roll body and shaft of grinding roller connecting portion, and described double cylinder roller bearing is positioned at roll body and the shaft of grinding roller connecting portion is inboard.
Be provided with cavity between described shaft of grinding roller and gland, described cavity is communicated with bearing, is fixed with door by the door bolt on described roll shaft, is arranged on lubricating oil pipe in shaft of grinding roller and is stretched out in cavity by door and carry lubricating oil.
The described shaft of grinding roller other end is installed on rocking arm.
The utility model has the advantage of that whole grinding roller is reliable and stable in the Vertical Mill running, vibrate little.The roller skin adopts tire shape, can effectively improve the grinding to material, the overlay cladding that roller skin grinding place is simultaneously used, after life cycle, the abrading section can carry out repair welding by the mode of online built-up welding, effectively improves the service life of grinding roller, both improved operating efficiency, provided cost savings again.
Description of drawings
The below is briefly described the content of every width accompanying drawing expression in the utility model specification and the mark in figure:
Fig. 1 is grinding roller of vertical mill apparatus structure schematic diagram;
Mark in above-mentioned figure is: 1, roller skin, 2, roll body, 3, conical ring, 4, set bolt, 5, gland, 6, door, 7, set bolt, 8, lubricating oil pipe, 9, double taper roll bearing, 10, double cylinder roller bearing, 11, grinding layer, 12, lining board for grinding discs, 13, shaft of grinding roller, 14, rocking arm.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help those skilled in the art, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding.
Referring to Fig. 1 as can be known, the grinding roller of vertical mill device is provided with a shaft of grinding roller 13, these shaft of grinding roller 13 1 ends are connected with rocking arm 14 and are fixed by rocking arm 14, the other end is fixed with ring-type roll body 2 by bearing, be fixed with the roller skin 1 of tire-like outside roll body 2, roller skin 1 surface is provided with overlay cladding, and roller skin 1 adopts the cast steel material casting to form, contain the high-abrasive material built-up welding such as chromium, nickel, molybdenum in the 1 overlay cladding use of roller skin and form, roll body 2 is to contain the manganese steel-casting.Utilize conical ring 3 and gland fastening after 1 assembling of roller skin, being roller skin 1 is provided with conical ring 3 with roll body 2 junctions, conical ring 3 is to be fixed on roll body 2 by set bolt 4, roll body 2 outer ends are provided with gland 5, such grinding roller structure is not only reliable and stable, reduce the difficulty on manufacturing process, and the service life that can effectively improve grinding roller.
During grinding roller work, shaft of grinding roller 13 is supported to tilt to stretch in Vertical Mill by rocking arm 14, and mill 12 is rotated in the rotation of reductor, after material enters, formation abrasive lapping layer 11 between grinding roller and mill 12, the rotation of mill drives grinding roller and rotates, and grinds material bed 11.Because shaft of grinding roller 13 is obliquely installed, vibration when slowing down the grinding roller grinding, bearing between shaft of grinding roller 13 and roll body 2 is made of 10 two kinds of double taper roll bearing 9 and double cylinder roller bearings, wherein double taper roll bearing 9 is positioned at roll body 2 and the shaft of grinding roller 13 connecting portions outsides, and wherein double cylinder roller bearing 10 is positioned at roll body 2 and shaft of grinding roller 13 connecting portions are inboard.
Shaft of grinding roller 13 is provided with lubricating oil pipe 8 entrances at rocking arm 14 1 ends, lubricating oil pipe 8 extends to the other end always in shaft of grinding roller 13, be provided with cavity between shaft of grinding roller 13 and gland 5, this cavity is communicated with bearing and is used to bearing to add lubricating oil, be fixed with door 6 by door bolt 7 on roll shaft 13, be arranged on lubricating oil pipes 8 in shaft of grinding roller 13 and stretched out in cavity by door 6 and carry lubricating oil.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
