Description

Blast cleaner for outer surface of steel pipe

A kind of outer wall of steel pipe shot-blast cleaning machine belongs to field of metal surface treatment technology, removes various outer wall of steel pipe surface rusty stain, oxide skin and blast sanded surface but be mainly used in, and is beneficial to anticorrosive coating and table of discovery planar defect.

In prior art, has only the cast(ing) surface shot-blast cleaning machine, the rigidity and the damping performance of its cleaning chamber are poor, work noise is big, no sealing device, and the contaminated environment and the bullet of easily dishing out are hurted sb.'s feelings, the charging aperture of its hoisting mechanism easily stops up, belt often skids, and can only be hung in cleaning chamber by cleaning piece, can not overturn at any time, clear up inhomogeneously, not thorough, often stay the dead angle; The helical blade of two kinds of rotation directions is respectively by two driven by motor on its auger conveyor, and waste motor, structure are not compact, and it also needs two-stage dust removal in addition, dirt ball disintegrate-quality is poor, the impeller head blade is short service life, can not get rid of the bulk foreign matter, and serious accident easily takes place.

The purpose of this utility model is to provide a kind of bullet recovering mechanism with the cleaning chamber of good seal, efficient impeller head, novelty, the steel pipe that good dirt ball separating mechanism and making is cleared up ceaselessly rotates while advancing and the oblique idler roller-way of adjustable speed, the above-mentioned every defective that exists in the prior art can be overcome and series of products can be made, the outer wall of steel pipe shot-blast cleaning machine that the steel pipe of various different-diameters can both use.

Basic principle and general technology requirement according to Treatment of Metal Surface, at the subject matter that exists in the prior art, basic design of the present utility model is: the shot-blast cleaning machine commonly used with the foundry machinery industry is that the basis is transformed: cleaning chamber adopts the steel plate welding, the two ends of interior wall liner Special Casting Iron slab and specific rubber plate and steel pipe turnover all install sealing device and oblique idler roller-way additional, set up inspection platform and auger conveyor and make it and the hoisting mechanism interlock, separator change into the BP formula and deduster changes cloth-bag type into, impeller head by yielding rubber pad or ring directly seat on cleaning chamber and in the middle of it and hoisting mechanism, install a pill-flowing valve additional, thereby realize purpose of design.

Of the present utility modelly be characterised in that described outer wall of steel pipe shot-blast cleaning machine, by cleaning chamber and by yielding rubber pad and support from lower to upper successively seat or be loaded on this impeller head above cleaning chamber, dust-pill separator, the bucket elevator structure and be loaded on this cleaning chamber nearby with this cleaning chamber and above-mentioned dust-pill separator between the deduster that is connected by pipeline and with the electricity consumption parts between the electrical control cubicles that is connected by lead constitute, the steel pipe of above-mentioned cleaning chamber is imported and exported two ends and all is equipped with by at least 2 roads and is enclosed within the sealing mechanism that rubber Curtain on the steel pipe and metal matter valve are formed, in case dust is raised outward and the shot of dishing out is hurted sb.'s feelings; The oblique idler roller-way of an adjustable speed is respectively established in this outside, two ends, so that being advanced while rotating, the steel pipe of being cleared up passes through cleaning chamber, auger conveyor and it and above-mentioned bucket elevator structure interlock are housed, in order to avoid the charging aperture of hoisting mechanism is blocked in cleaning chamber one end front lower place; Inspection platform also is housed on the support on above-mentioned cleaning chamber, between above-mentioned hoisting mechanism and impeller head pill-flowing valve is housed, above-mentioned in addition deduster is the one-level cloth-bag type, and promptly complete machine only needs deduster.

The shape of above-mentioned cleaning chamber can justify, can just, also can be polyhedron shape, be welded by steel plate, and its inwall is lined with Special Casting Iron slab and two kinds of wall liners of specific rubber plate, not only wear-resisting but also damping.

Above-mentioned auger conveyor for the blade of two kinds of rotation directions is housed on the same axis, by a driven by motor, is concentrated to the centre by both sides to realize material, or by the purpose of centre to the both sides dispersion.Above-mentioned oblique idler roller-way is the V-type oblique idler, and all there is sprocket wheel on both sides, is connected by chain between each carrying roller and is driven by variable speed electric motors, particularly and decelerator, and the stepless speed regulation running is to adapt to the speed that the different tube diameters steel pipe advances.

Outstanding advantage of the present utility model is: the cleaning chamber good seal, taked multinomial glissando again and matched with fiber bag precipitator, so free from environmental pollution, the safety of this machine, work noise are lower than 85 decibels, sturdy and durable, hoisting mechanism and auger conveyor interlock, it is blocked both can to have avoided promoting charging aperture, can avoid belt creep stopping accident to occur again; The oblique idler roller-way of adjustable speed is housed, the steel pipe of various different-diameters is advanced while rotating with rational speed pass through cleaning chamber, the dead angle evenly, thoroughly, is not stayed in the outer wall of steel pipe cleaning, the blade of adorning two kinds of rotation directions on the auger conveyor same axis is by a driven by motor, both be convenient to material and concentrated or disperse to both sides, and can save motor again, reduce cost, make compact conformation by the centre from both sides to the centre; Adopt BP type dust-pill separator, the disintegrate-quality height both can be got rid of the bulk foreign matter, avoided impeller head generation serious accident, can prolong the service life of blade again; Inspection platform is housed, and the machine installation and maintenance are convenient, and this machine can be made into and is adapted to the series of products that the different-diameter steel pipe needs in addition, and is of many uses, can clear up the outer surface of steel tube of diameter 20--1100mm.
