Description
Technical field
The present invention relates to the hydroelectric project operating technique, specifically, relate to the concreting machinery conveyer.
Background technology
The high spud angle corrugated flange blet conveyor is a kind of later-model belt conveyer; Its structural principle is the rubber waveform vertical " shirt rim " that is stained with retractable in flat shape rubber conveyor belt both sides; Between the shirt rim, be stained with certain intensity and elastomeric cross wall again and form the box bucket; Material is carried in bucket continuously, and the conveying scope can several meters high high to tens meters.Industrialized country is used widely abroad, is mainly used in industries such as coal, building materials, metallurgy, chemical industry, harbour, electric power, and in ambient temperature was-19 ℃～40 ℃ scopes, the conveying bulk specific weight was 0.5-2.5t/m
3Various bulk materials, like the medium that aggregate, ore etc. are block, cohesiveness is lower.
Its inclination angle of conventional belt conveyer reaches bigger hoisting depth generally below 20 ° like need, shortcomings such as fed distance is long, floor area is big, civilwork engineering quantity is big, technology arrangement complicacy will occur.In recent years, for reducing land seizure, reducing construction investment and operating cost, realize energy-saving and cost-reducing an urgent demand, the high spud angle corrugated flange blet conveyor is applied because of its particular structure and outstanding feature just step by step.This machine is suitable to transport various dried bulk cargos, but moisture surpasses at 10% o'clock, and the material of conveying just can stick to and cause not easy-clear totally and not of discharging on cross wall or the rib; And its tape surface has adopted the bucket of wave baffle board at its edge and cross wall to rise structure, can't scraper blade cleaning device be installed as the ordinary straps machine, but pats cleaning through the eccentric wheel beating device of head horizontal segment.
Roller compacted concrete belongs to does poor property (ultra-dry stiff) cement concrete; But behind Binder Materials such as the cement in the concrete proportioning, fly ash, ground phosphate rock, additive, air entraining agent and the aggregate water mixing mix certain adhesiveness is arranged; By the general slave mode beating device (relying on load-transfer device to drag the beating device that makes its rotation) of carrying the high spud angle corrugated flange blet conveyor design setting of dried bulk cargo; Slap to cement mortar in certain adhering roller compacted concrete, fine aggregate etc. are arranged is very undesirable; The backhaul load-transfer device will be taken back cement mortar, the fine aggregate in a small amount of roller compacted concrete of loss; Cause the variation of VC value, air content and proportioning, cause the standard specimen mean compressive strength to reduce, quality of concrete is had certain influence; Therefore need take effective measures, to reduce the adhesion of base band, cross wall and shelves limit to cement mortar and fine aggregate; The loss of the cement mortar of must strict control backhaul load-transfer device taking back, fine aggregate etc. reduces aggregate separated, with each item performance figure of guaranteeing roller compacted concrete, the quality of roller compacted concrete is unaffected in transportation.
