Modern industry fast development makes the wearability of equipment to parts have higher requirement, as cement, mine, metallurgical, the grinding roller of the vertical grinder used in power station or various similar industry, mill and plate hammer for crusher etc., the hardness of conventional steel iron material and toughness normally contradiction, prior art many employings bimetallic compound and ceramet complex technique improve the wearability of material, the main wear-resisting position of this series products consumes completely, because wearability is lower, use value reduces at ductile metal position, but because itself and wear-resisting position are linked together by metallurgical binding and cannot realize dismantling, usually will as waste disposal, this will cause a large amount of wastings of resources.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of combined vertical wear resistant roll of the energy quick-replaceable abrading section fan-shaped wear-resistant block and the split of grinding roller body arranged, and can reach the effect of recycling grinding roller body.
To achieve these goals, the technical solution of the utility model is as follows: a kind of combined vertical wear resistant roll, comprise the grinding roller body of taper, it is characterized in that: the outer circumference surface of described grinding roller body is distributed with some axially extended grooves, hook groove is provided with near grinding roller body osculum end in groove, the notch of described hook groove is towards the osculum end of grinding roller body, ring baffle is provided with at the big opening end of the outer circumference surface of grinding roller body, on described ring baffle, corresponding each groove is provided with two positioning through hole that axis extends along grinding roller body axis, inserting bolt in a positioning through hole wherein, the head of described bolt is arranged in groove,
The outer circumference surface of grinding roller body is distributed with some fan-shaped wear-resistant blocks, the lower surface of the small end of described fan-shaped wear-resistant block be provided with to downward-extension with the hook of hook slot fit, the large end of described fan-shaped wear-resistant block is provided with limited post and bolt draw-in groove, described fan-shaped wear-resistant block is contained in groove, its top reaches outside groove, the extension of all fan-shaped wear-resistant blocks surrounds conical ring, the hook of described fan-shaped wear-resistant block hooks in hook groove, the limited post of described fan-shaped wear-resistant block inserts in another positioning through hole of ring baffle, the head of described bolt stretches in bolt draw-in groove, and fan-shaped wear-resistant block is locked by nut in the outside of ring baffle.
Wear-resisting for entirety roller shell is divided into the fan-shaped wear-resistant block of fritter by the utility model, convenient with the installation and removal of grinding roller body, solves the problem of large-scale vertical taper grinding roller installation and removal difficulty.When partial sector wear-resistant block damages, only can change the fan-shaped wear-resistant block of this partial destruction, can reuse for unspoiled fan-shaped wear-resistant block and grinding roller body, avoid the waste causing resource, reduce manufacturing cost.
Fan-shaped wear-resistant block and grinding roller body, by realizing the location of fan-shaped wear-resistant block under hook groove and hook cooperation, limited post and the cooperation of positioning through hole and the effect of bolt, connect reliable, easy installation and removal.
Arranging ring baffle at the large end of grinding roller body, is because the structure of large-scale vertical taper grinding roller itself causes in use, and fan-shaped wear-resistant block easily slides to big opening end, arranges baffle plate and fan-shaped wear-resistant block can be avoided to the slip of large end.
Finally we are by wear-resisting roller shell fritter, split casting, reduce the difficulty of the operations such as shaping, processing, heat treatment, improve yield rate.
In such scheme: described fan-shaped wear-resistant block is by antifriction metal (AFM) or metal alloy or ceramet high-abrasive material casting.
In such scheme: described fan-shaped wear-resistant block is by rich chromium cast iron or ni-hard cast iron or steel alloy casting, or described fan-shaped wear-resistant block has the ceramic-metal composites casting of ceramic oxide particle or carbide ceramic particles or compound ceramic particle by Near Surface Mounted.Fan-shaped wear-resistant block anti-wear performance obtained is thus good.
In such scheme: described grinding roller body is made up of cast iron or cast steel.
Preferred: described grinding roller body is made up of spheroidal graphite cast-iron or graphitic steel.These materials have obdurability simultaneously.
In such scheme, described grinding roller body and ring baffle integrally casting shaping.
Beneficial effect: the utility model is by wear-resisting roller shell and grinding roller body split design, and wear-resisting roller shell is divided into some fan-shaped fritters, reduce difficulty of processing, improve yield rate, avoid the phenomenon causing because of the wearing and tearing of roller cover directly also being scrapped by grinding roller body simultaneously, reduce costs, the installation and removal of fan-shaped wear-resistant block and grinding roller body are convenient, and bonding strength is strong.
