Abstract
Provided is an end face protection device of a roller sleeve of a high pressure roller grinder with the column nail roller surface. A smooth round ring formed by fixing a plurality of abrasion-resisting plates for locating a plurality of fixing plates on the lateral face of the roller sleeve through bolts. The tops surfaces of the abrasion-resisting plates are connected with the roller sleeve through welding, and an abrasion-resisting overlaying welding layer is formed on the top surface of the roller sleeve. The end face protection device of the roller sleeve of the high pressure roller grinder with the column nail roller surface effectively prevents a hard alloy column nail of the roller surface from shedding and prolongs service life of the lateral face of the roller sleeve.
Description
Affiliated technical field: efficient, the energy-conservation disintegrating apparatus of novel ore deposit rock
The utility model is designed a kind of protector of novel post nail roll surface high-pressure roller mill roller shell end face; Especially can bear elevated pressures, can improve the abrasion resistance of roller shell end face greatly, can effectively prevent to cause the post nail on the roll surface to come off owing to the layer wearing and tearing of roller shell end face from the extruding of ore deposit rock; Improved the service life of roller shell; And volume is little, and is in light weight, easy to replace and maintain.
Background technology
High-pressure roller mill is the novel energy-conserving milling equipment of the eighties appearance in mid-term, is that cement grinding and metallic ore are pulverized one of intermediate equipment in the link, realizes the key equipment of how broken few mill, can reduce energy resource consumption significantly.High-pressure roller mill has obtained applying greatly in the cement field; But because roll surface wear; Pulverizing at the ore of metal mine still is in the starting stage; Adopt the roll surface of hard alloy columnar nail, greatly improved the abrasion resistance of roll surface, make high-pressure roller mill obtain breakthrough progress in the pulverizing of the ore of metal mine.When powder ore, in order to improve roll-in efficient, prevent that material is overflowed in the cavity, must surround a relative hermetic cavity body with two side shields in the side of two roller shells.When roller shell rotates with linear velocity 1～3 meter per second; Tightly being pressed on the roller shell side of two side shields; Cause the wear extent of roller shell and side shield all very big, because roller shell adopts intensity and all higher material of hardness, size is (the roller shell external diameter can reach 2 meters) greatly also; Heavy Weight (the roller shell substance reaches 30 tons), on-the-spot being difficult to repaired after wearing and tearing.In order to improve the wearability of roller shell, present method in common is to adopt wear resistance electrode that built-up welding is carried out in the end face and the side of roller shell end.Since the overlaying surface out-of-flatness, and be difficult to processing, must leave the gap in the side of side shield and roller shell, caused material effusion in the cavity.Because the edge effect between ore and the rod cover end face in the course of the work; Make the overlay cladding of end face come off easily, and further cause the end face overlay cladding to come off, thus the coming off of hard alloy columnar nail of causing roll surface; Be merely 2～3 months its service life, and equipment operation rate reduces greatly.
Summary of the invention
In order to overcome the technical deficiency of existing equipment, the compound mode of wear-resistant composite board splicing is adopted in the side that the utility model provides the end face of roller shell end to adopt wear resistance electrode built-up welding and roller shell end.
The utility model solves the technical scheme that its technical problem adopted: a kind of roller shell end face protector of post nail roll surface high-pressure roller mill; Be connected with roller shell at the abrasion-proof composite plate of roller shell end face by easily detachable; The easily detachable wearing plate is connected through retainer ring with roller shell; End face at the roller shell end face is fixed wearing plate with welding manner, and forms overlay cladding.
Further, wearing plate and retainer ring are multi-disc, and are spliced into a smooth annulus by multi-disc.
Further, wearing plate and retainer ring adopt wedge surface and bayonet socket form.
The end face of roller shell end adopts the mode of whole built-up welding, fuses into one with roller shell, in use difficult drop-off.The mode of wear-resistant composite board splicing is adopted in the side of roller shell end, and fixes wear-resistant composite board with retainer ring.Wear-resistant composite board by polylith is spliced into a smooth annulus, realizes that the side of roller shell closely contacts with side shield.This mode has greatly reduced the edge effect between ore and the rod cover end face, has reduced the impact between the side of ore and roller shell end simultaneously, owing to the high-wearing feature of wear-resistant composite board, has protected the side of roller shell.Adopt this kind structure, can protect the end face wearable overlay of roller shell end well, prevent the coming off of hard alloy columnar nail of roll surface, prolonged the service life of roller shell side,
The result of use of the utility model is: in the post nail roll surface high-pressure roller mill course of work, roller shell realizes that the side of roller shell closely contacts with side shield in running; And wear extent is little; Effectively prevent the coming off of hard alloy columnar nail of roll surface, the life-span of roller shell prolongs, and is simple in structure.
