Description
Technical Field
The utility model relates to an online grinding roller device that can extensively be used for four roller equipment.
Background
As is well known, the sintering plant of an iron works is an important component of the whole iron-making system, is the first place of production of iron works raw materials, and plays a significant role in normal production operation. The fuel is the key for sintering the sinter, and the crushing of the fuel in a four-roller fuel crushing chamber is an important process before sintering, wherein the crushing granularity of the fuel has strict technical requirements and control standards, and the quality and the yield of sintering the sinter are seriously influenced if the crushing granularity does not reach the standard.
With the continuous progress of the fuel crushing process, the abrasion degree of the middle part and the edge part of the roller equipment is inconsistent due to the uneven blanking of the four-roller equipment, so that tiny depressions can be formed between the rollers, and the fuel crushing granularity can not reach the standard in the past, thereby influencing the quality and the yield of the sintering ore.
According to the traditional method, when the deviation between the granularity of the raw materials and the standard granularity is overlarge, the standby rollers are replaced regularly, the replacement period is generally three days, and the rollers which are off-line are repaired off-line, so that a large amount of manpower, material resources and financial resources are wasted, and the quality and the yield of the sinter are influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides an online grinding roller device for four roller equipment realizes online adjustment and the restoration of roller.
According to the utility model discloses an aspect provides an online grinding roller device, including sleeve, wearing parts and adjustment mechanism, wearing parts is located the sleeve can be followed sleeve lower extreme opening and stretched out the effect of hugging closely on the roller surface and reaching online grinding roller under adjustment mechanism's the effect. The adjustment mechanism includes:
the baffle is positioned above the wear-resistant part in the sleeve;
the two ends of the supporting piece are fixed and are positioned above the baffle;
an adjusting part located above the support;
the screw rod penetrates through the adjusting part and the supporting part and then is connected with the baffle;
the spring is sleeved on the lead screw, one end of the spring is connected with the supporting piece, and the other end of the spring is connected with the adjusting part;
the screw rod nut is sleeved on the screw rod and is positioned above the adjusting part;
in the above-mentioned on-line grinding roller device, both ends of the supporting member are fixed to the sleeve.
Under the effect of the prestress of the spring, the wear-resistant part is always tightly attached to the surface of the roller, the effect of continuously grinding the roller on line is achieved, the maintenance time of the roller equipment is shortened, the service life of the roller equipment is prolonged, the cost is saved, the production efficiency is improved, and the waste of unnecessary manpower and material resources is reduced.

Detailed Description
Fig. 1 shows a schematic structural view of an on-line grinding roll arrangement for a four-roll plant according to an embodiment of the present invention. Referring to fig. 1, the online grinding roller device comprises a sleeve 1, a wear-resistant part 7 and an adjusting mechanism, wherein the sleeve 1 is welded and fixed on a four-roller equipment sealing cover, the wear-resistant part 7 is positioned in the sleeve 1, and can extend out from an opening at the lower end of the sleeve 1 to be tightly attached to the surface of a roller under the action of the adjusting mechanism, so that the effect of online grinding roller is achieved. Wherein, the wear-resistant part 7 can be made of the same material as the grinding wheel.
Referring to fig. 1 to 3, the adjusting mechanism comprises a screw 2, a spring 3, a support 4, a baffle 6 and a screw nut 8; the baffle 6 is positioned above the wear-resistant part 7 in the sleeve 1; two ends of the supporting piece 4 can be fixed on the sleeve 1 and positioned above the baffle 6; the adjusting part 5 is positioned above the baffle 6; the screw rod 2 passes through the adjusting part 5 and the support 4 and then is connected with the baffle 6; the spring 3 is sleeved on the screw rod 2, one end of the spring is connected with the supporting piece 4, and the other end of the spring is connected with the adjusting part 5; the screw nut 8 is sleeved on the screw 2 and is positioned above the adjusting part 5.
Compress tightly spring 3 between support piece 4 and the adjusting part 5 through adjusting nut 8, make wearing parts 7 hug closely the roller surface and reach the effect of online grinding roller, when abrasive brick appears wearing and tearing, under the effect of spring prestressing force, make abrasive brick hug closely the roller surface all the time, reach the effect of lasting online grinding roller, the maintenance time of equipment has been reduced, the life of roller equipment has been improved, the cost is practiced thrift, the waste of unnecessary manpower and materials has been reduced, the quality of sintering deposit has been guaranteed, and the production efficiency is improved.
