Description
Technical field
The present invention relates to a kind of carrying roller, be specially a kind of ribbon conveyer wear-resistance and anti-corrosion composite roller and preparation method thereof.
Background technology
Ribbon conveyer is that the industries such as Mine haul, electric power, chemical industry, metallurgy, harbour use relatively broad a kind of conveying equipment, load is mainly placed on belt by it, by driving the displacement of belt, by material transportation to desired location, below belt, generally it is provided with multiple cylindrical idler machining back-up belt.Existing carrying roller typically uses metal material to make, for cylinder, and conveyer belt generally rubber is made, carrying roller and the conveyer belt loud noise that phase mutual friction sends in operation, and the carrying roller of metal manufacture is easily corroded when acid or alkali environment operation, Long-Time Service easily produces cutting edge, cuts and scrapes conveyer belt, reduces the service life of conveyer belt.Additionally, existing carrying roller water proof and dust proof sealing property is poor, largely effect on its service life and serviceability.
Summary of the invention
The present invention is to solve the problem that existing carrying roller exists above-mentioned shortcomings, it is provided that a kind of ribbon conveyer wear-resistance and anti-corrosion composite roller and preparation method thereof.
The present invention adopts the following technical scheme that realization: a kind of ribbon conveyer wear-resistance and anti-corrosion composite roller, including the roll body being coaxially disposed, axle, bearing, bearing block, roll body two ends are fitted together with axle, bearing group by bearing block respectively, roll body is respectively arranged at two ends with sealing lid, innovative point of the present invention is along the axial direction of axle and is positioned at inside bearing and is provided with retaining ring for shaft shoulder, axle circlip, being sequentially arranged with circlip for hole, labyrinth type sealing ring outside bearing and between sealing lid, close closure skirt is equipped with the outer circlip of axle.Use the structure design of the present invention, using multi-sealed between roll body and axle, bearing, fully ensured that the water proof and dust proof performance of carrying roller, the sealing especially by labyrinth type sealing ring coordinates, both increase the flow resistance during medium is revealed, also play more preferable water proof and dust proof effect.
Described labyrinth type sealing ring and the cavity sealed between lid are filled with lithium saponify lubricating oil, play the effect of supplemental lubrication；Described axle is light pulling shaft.Described bearing is big play bearing.To prevent conveyer long time running high-temperature expansion from causing burn-out of bearing locking, extend the service life of carrying roller.
A kind of method preparing described ribbon conveyer wear-resistance and anti-corrosion composite roller, described roll body is made up of 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 high temperature 1350 DEG C fusing, 880-920 DEG C of crystallization, broken, make 140-160 mesh 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, will mixing after mixed material be delivered to extruder, be heated to 150 ~ 250 DEG C, extrusion；D, then extruded stock is put into mould, through hydraulic press under the pressure of 20-30MPa compressing, obtain roll body；E, roll body and bearing, axle, sealing ring, back-up ring are assembled, i.e. obtain carrying roller of the present invention.
The present invention uses basalt through broken, abrasive dust, dispensing, extruded, the material with excellent abrasion-proof corrosion-proof performance that the techniques such as machining prepare, basalt is utilized to have the most corrosion-resistant, the feature of anti-wear performance, use it for making carrying roller, carrying roller is made to have excellent wear-and corrosion-resistant characteristic, the most also there is toughness and the feature of the resistance to temperature difference, solve other materials carrying roller and be not suitable for acid or alkali environment and the problem of short-term just time abrasion, conveyer belt and the other materials carrying roller loud noise that phase mutual friction sends in operation can be overcome simultaneously, improve working environment.
In order to prove the premium properties of carrying roller of the present invention further, the present invention has also done tests below,
Testing one, composite roller wall thickness is designed as 25mm, after installation operating in 150 hours, actual measurement radius abrasion is 0.73-0.66mm.Calculate that roll body all polishes by these data and about need about 14 years, consider uneven wear and the on-the-spot unfavorable factor that cannot estimate, lifetime safety factor is by 3 calculating, then thick for 25mm roll body, life-span was up to 4.6 years, because having good two-way labyrinth type waterproof and dustproof to seal and lithium saponify lubrication, 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 square centimeter loses2SO4Less than 0.01 milligram, 20%NaOH is less than 0.15 milligram.Prove that it has excellent acidproof, alkaline resistance properties.
Compared with prior art, present configuration is advanced, manufacture craft is fine, function admirable, and this carrying roller uses special big play, low noise Special bearing for carrier rollers, oil clearance be C4 precision be G level, use good two-way labyrinth type dustproof and waterproof to seal, and with lithium saponify fill lubrication, guaranteeing the sealing property having good anti-dust and water to pollute, its working life guarantees more than 20000 hours.Not only there is wear-resisting, anticorrosion, dust-proof, waterproof good characteristic, but also there is the feature such as toughness and the resistance to temperature difference, substituting other materials carrying roller of having filled up is not suitable with acid or alkali environment operation and the drawback of short-term just abrasion, also overcome conveyer belt and the other materials carrying roller loud noise that phase mutual friction sends in operation simultaneously, improve working environment；Compare with steel carrying roller, the carrying roller weight of same size is the lightest by 1/4, equipment energy consumption can be reduced, alleviate support load-bearing and the labour intensity of maintenance fortune dress carrying roller, Main Economic technical indicator has met or exceeded domestic and international carrying roller advanced level, is widely used in the various rubber conveyers of all trades and professions such as metallurgy, electric power, coal, harbour, mine, chemical industry, food.
