Description
Technical field
A kind of grinding roller is the utility model is related to, more particularly to a kind of assembled wear-resistant grinding roller, belongs to milling disintegrating apparatus
Technical field.
Background technology
Each discharge plate roller mill powder is largely used in industries such as coal, metallurgy, mine, electric power, building materials, refractory material, the energy
Machine and disintegrating machine, the grinding roller wear-out part main as one among these, the height of its rub proofness, the length of service life, one
Determine to determine the economic benefit of enterprise in degree.The metal wear resistant material grinding roller of the grinding roller used at present, predominantly monoblock cast.
This grinding roller is due to using single metal material, and grinding roller is because installation requirement needs to be machined, therefore hardness can not
It is too high, the machining property of grinding roller is otherwise influenceed, therefore cause that monoblock cast grinding roller wearability is poor, and service life is shorter.
To improve the service life of grinding roller, the method used at present is to use casting bimetal composite grinding roll, and grinding roller outer layer is using high resistance to
Material such as rich chromium cast iron, ni-hard cast iron etc. of performance are ground, grinding roller internal layer uses the material such as carbon structural steels of preferable toughness.Production
During first grinding roller internal layer, i.e. roller core are produced, then roller core is placed in sand mold and pours into a mould grinding roller outer layer i.e. outer roller again,
Both are made to be combined with each other, outer roller serves wear-resisting during work, and internal layer roller core plays connection supporting role, is convenient for being machined
To meet the requirement of assembling.The grinding roller of this technique productions is with respect to the abrasive roller of monoblock cast mono-material, and anti-wear performance is significantly
Improve, the requirement generally to abrasive roller service life can be met.But this grinding roller is also deposited in actual use
Following the problem of：Because grinding roller outer roller and roller core are the inside and outside overall grinding roller connected as one, thus in use when
After wear out failure occurs in outer roller, although now no damage occurred for roller core, remain to normal use, due to both be connected as it is whole
Body, it is still to dismantle with outer roller and integrally scraps.In use, it is different in the height direction that it wears to other grinding roller
, the difference of the degree of wear is also very big in the case of having, and generally middle abrasion is very serious, and abrasion is more slight up and down,
In this case, when the size scrapped is may wear among grinding roller, although abrasion is smaller up and down, it is still to entirety and scraps, because
This causes very big waste, needs solve this problem using new process and structure for this.
The content of the invention
A kind of assembled wear-resistant grinding roller for broken material is described wear-resisting comprising roller core, wear resistant roll skin, connecting bolt
Roller skin is provided with counterbore, and the roller core is provided with screwed hole, and the connecting bolt passes through on the counterbore and roller core on wear resistant roll skin
Screwed hole wear resistant roll skin is connected on roller core.
The wear resistant roll skin is divided into 3 ~ 6 circles in grinding roller short transverse.
Each circle wear resistant roll skin is split into 3 ~ 6 pieces in grinding roller short transverse.
Each piece of wear resistant roll skin is attached by least three bolts.
The connecting bolt is interior six point cylindrical head bolt.
Pass through the fritter being separated from each other that grinding roller outer roller is split into along in grinding roller short transverse and arranged on circumferencial direction
Wear resistant roll skin, and these wear resistant roll skins are connected on roller core by bolt, after wear out failure occurs in wear resistant roll skin, only pass through
Change wear resistant roll skin can be continuing with grinding roller, avoid because outer roller wear out failure need integral replacing grinding roller the problem of, can
To substantially reduce the use cost of grinding roller, the advantages of having clearly.Further, since wear resistant roll skin is in grinding roller short transverse
It is divided into some circles, is adapted to the operating mode that the degree of wear differs in grinding roller short transverse, serious wear needs in grinding roller middle part
In the case of scrapping, only by change among grinding roller one circle or a few wear resistant roll skins can be continuing with grinding roller, avoid
The problem of needing all to change grinding roller outer roller because of the concentrated wear of grinding roller outer roller, also have very much to the use cost for reducing grinding roller
Profit.
Hole is threaded on roller core, counterbore is set on wear resistant roll skin, connecting bolt uses interior six point cylindrical head bolt,
It is easy to the installation and dismounting of wear resistant roll skin, there is clear advantage in terms of the maintenance convenience of equipment.
Because wear resistant roll skin is fixed on roller core mainly by connecting bolt, thus bolted reliability to grinding roller just
Often work has very important influence.In order to ensure the reliability of connection, each piece of wear resistant roll skin is at least using three connections
Bolt, so in the grinding roller course of work, even if there is a connecting bolt to go wrong, still ensure that the reliable work of wear resistant roll skin
Make.
Counterbore is set on wear resistant roll skin, and is attached using interior six point cylindrical head bolt, can both facilitate wear resistant roll skin
Installation when can also avoid installing/dismounting the problem of spanner insufficient space.
Brief description of the drawings
Accompanying drawing show the structure and installation diagram of the utility model specific embodiment, and wherein Fig. 1 is C-C positions in Fig. 2
Sectional view, Fig. 2 are the sectional view of B-B in Fig. 1.
Embodiment
In the embodiment shown in attached Fig. 1 and 2, each part sequence number meaning is as follows：Sequence number 1 is wear resistant roll skin, and sequence number 2 is company
Connecting bolt, sequence number 3 are roller core, and sequence number 4 is the counterbore on wear resistant roll skin, and sequence number 5 is the screwed hole on roller core.
When grinding roller produces, first roller core is cast out to come, roller core material selection mild steel.It is processed after cleaning, and
The relevant position thread mill drilling on the roller core corresponding to wear resistant roll skin.By regulation profile casting wear-resistant roller skin, wear resistant roll skin is adopted
Make of rich chromium cast iron material, after the completion of casting, be heat-treated accordingly, improve the hardness of wear resistant roll skin.Heat treatment is completed
Afterwards, assembled using interior six point cylindrical head bolt on roller core, wear resistant roll skin is divided into 3 circles, each circle along grinding roller short transverse
It is divided into 4 pieces, each piece of roller skin is attached using 3 connecting bolts.After the completion of assembling, used on disintegrating apparatus.
During use, after the wear resistant roll shelling damage of centre, to be dismantled, the wear resistant roll skin more renewed, up-down rollers skin is changed without, because
This can substantially reduce the use cost of grinding roller.If the wear resistant roll shelling damage in short transverse is basically identical, disposably more
All wear resistant roll skins are changed, but roller core mechanical can still use, and it also avoid because what outer roller wear out failure was brought needs integral replacing
The problem of grinding roller.
