Description
Technical field
The present invention relates to a kind of carrying roller, be specially wear-resistance and anti-corrosion composite roller and preparation method thereof for a kind of belt conveyer.
Background technology
Belt conveyer is that the industries such as mine transportation, electric power, chemical industry, metallurgy, harbour are used a kind of load transfer device comparatively widely, it is mainly that load is placed on belt, by driving the displacement of belt, material transportation, to desired location, is provided with to a plurality of cylindrical carrying roller group back-up belts conventionally below belt.Existing carrying roller generally adopts metallic material to make, for cylindrical, and being generally rubber, makes belt conveyor, the larger noise that carrying roller and belt conveyor phase mutual friction in operation are sent, and the carrying roller of metal manufacture is easily corroded when acid or alkali environment operation, long-term use easily produces cutting edge, cuts and scrapes belt conveyor, reduces the service life of belt conveyor.In addition, existing carrying roller water proof and dust proof sealing property is poor, greatly affects its service life and in-use performance.
Summary of the invention
There is the problem of above-mentioned shortcomings in the present invention, wear-resistance and anti-corrosion composite roller and preparation method thereof for a kind of belt conveyer is provided in order to solve existing carrying roller.
The present invention adopts following technical scheme to realize: a kind of belt conveyer wear-resistance and anti-corrosion composite roller, the roll body, axle, bearing, the bearing seat that comprise coaxial setting, roll body two ends are fitted together by bearing seat and axle, bearing set respectively, roll body two ends are respectively equipped with seal cover cap, innovative point of the present invention is along the axial direction of axle and is positioned at bearing inner side retaining ring for shaft shoulder, axle circlip are installed, between bearing outside and seal cover cap, circlip for bore, labyrinth type sealing ring are housed successively, the outer circlip of axle is equipped with in seal cover cap outside.Adopt structure design of the present invention, between roll body and axle, bearing, adopt multi-sealedly, fully guaranteed water proof and dust proof performance, especially being sealed and matched by labyrinth type sealing ring of carrying roller, both increase the resistance to flow in medium leakage process, also played better water proof and dust proof effect.
Cavity between described labyrinth type sealing ring and seal cover cap is filled with lithium grease lubricating oil, plays the effect of supplemental lubrication; Described axle is light pulling shaft.Described bearing is large play bearing.To prevent conveyer long time running high-temperature expansion, cause burn-out of bearing locking, extended the service life of carrying roller.
Prepare a method for wear-resistance and anti-corrosion composite roller for described belt conveyer, described roll body is to be made by the raw material of following weight ratio, basalt powder 50-60%, high density polyethylene (HDPE) powdered resin 30-40%, acetylene conductive black 2-4%, graphite powder 2-4%, antimony oxide 1-3%; Described preparation method comprises the following steps: A, basalt, through 1350 ℃ of fusings of high temperature, 880-920 ℃ crystallization, fragmentation, are made 140-160 order basalt powder through grinding machine; B, basalt powder, high density polyethylene (HDPE) powdered resin, acetylene conductive black, graphite powder and antimony oxide are mixed according to above-mentioned part by weight; C, the mixed material after mixing is delivered to extrusion press, is heated to 150 ~ 250 ℃, extrude; D, then extruded stock is put into mould, compressing under the pressure through hydraulic compressor at 20-30MPa, obtain roll body; E, by roll body and bearing, axle, seal ring, back-up ring assembling, obtain carrying roller of the present invention.
The present invention adopts basalt through fragmentation, abrasive dust, batching, extrusion forming, the material with excellent abrasion-proof corrosion-proof performance that the techniques such as machine up make, utilize basalt to there is good withstanding corrosion, the feature of wear resisting property, use it for making carrying roller, make carrying roller there is good wear-and corrosion-resistant characteristic, also there is the poor feature of toughness and heatproof simultaneously, solved that other materials carrying roller is not suitable for acid or alkali environment and short-term is just returned the problem of wearing and tearing, simultaneously can overcome the larger noise that belt conveyor and the phase mutual friction in operation of other materials carrying roller are sent, improved working environment.
In order further to prove the premium properties of carrying roller of the present invention, the present invention has also done following test,
Test one, composite roller wall thickness is designed to 25mm, after within 150 hours, turning round through installing, the wearing and tearing of actual measurement radius are 0.73-0.66mm.By these data, calculate that the whole polishings of roll body approximately needed about 14 years, consider irregular wear and the on-the-spot unfavorable factor that cannot estimate, lifetime safety factor calculates by 3, the thick roll body of 25mm, life-span can reach 4.6 years, because having good two-way labyrinth type waterproof and dustproof sealing and lithium grease lubricated, guarantee 20000 hours (about 2 years) service life.
Test two, the test of acid-fast alkali-proof degree, at room temperature soak roll body sample 100 hours, the milligram number 98%H that every sq cm loses
2sO
4be less than 0.01 milligram, 20%NaOH is less than 0.15 milligram.Prove that it has good acidproof, alkaline resistance properties.
Compared with prior art, structure of the present invention is advanced, manufacture craft is meticulous, function admirable, and this carrying roller adopts special-purpose large play, low noise Special bearing for carrier rollers, oil clearance is that C4 precision is G level, adopts good two-way labyrinth type dustproof and waterproof sealing, and with lithium grease, fills lubricated, guarantee the sealing property that has good anti-dust and water to pollute, its work life is guaranteed more than 20000 hours.The good characteristic not only with wear-resisting, corrosion prevention, dustproof, waterproof, but also there is toughness and the feature such as heatproof is poor, the substituting other materials carrying roller of having filled up is not suitable with acid or alkali environment operation and the drawback of short-term with regard to wearing and tearing, simultaneously also overcome the larger noise that load-transfer device and the phase mutual friction in operation of other materials carrying roller are sent, improved working environment; With the comparison of steel carrying roller, the carrying roller weight of same size is approximately light by 1/4, can reduce equipment energy consumption, alleviate the labour intensity of support load-bearing and maintenance fortune dress carrying roller, Main Economic technical index has met or exceeded domestic and international carrying roller advanced level, is widely used in the various travelling aprons of all trades and professions such as metallurgy, electric power, coal, harbour, mine, chemical industry, food.
