Abstract

The utility model provides a regenerating device for asphalt concrete, which is composed of a metal cylinder arranged aslant, a dynamic rotary mechanism, a heating mechanism, a stirrer fixed in the metal cylinder and a metal net. Asphalt concrete fragments generated from the excavation of the engineering, such as the overhauling of asphalt pavements or pipes and electrical cable laying, etc., are thrown into the metal cylinder, turned, stirred and heated to be crushed and softened. Fine fragments are further separated and crushed after passing through the metal net. At last, granules mixed evenly are formed, are sieved by a tubular metal net and are leaked. The device can treat the regeneration of large quantity of asphalt waste materials, which is favorable for saving resources and reducing environment pollution.

Description

Reprocess device for slag of bituminous concrete

The present invention relates to a kind of Aided Machine of building the road, particularly a kind ofly be used to handle the bituminous concrete waste material, the mechanical device that asphalt-regenerating is wherein utilized.

The black flexible pavement occupies very big proportion in highway construction, the use amount of pitch is huge.Produce a large amount of bituminous concrete fragments because of engineering excavation road surfaces such as pavement recapping or tubing, cables simultaneously,, not only waste resource but also contaminated environment as these fragments are abandoned.Because the fusing point height of pitch, viscosity is big, combines firmly with fillers such as sand, stones, and desire is separated pitch with filler, makes its regeneration to utilize, and then workload is big, and acquires a certain degree of difficulty.Therefore, press for special-purpose machinery, had not yet to see this class machinery and gone on the market.

The application's task provides a kind of special disposal bituminous concrete waste material, and pitch is separated with husky, stone, is able to the mechanical device of regeneration.

Present design is as follows: be obliquely installed a large-scale metallic cylinder, the dynamic mechanism of tube outer join is to drive it around self axis rotation.Actuating unit and bind mode thereof can utilize prior art (for example motor, reductor and gear drive or diesel engine and belt pulley transmission or the like).Also be provided with heating arrangements simultaneously to cylinder heating (also using prior art, for example electrical heating or oils burner heating).Be fixed with many agitators on the cylinder inner wall, this agitator can be some pointed cones or polyhedron, projection radially in tube.Drop into the fragment of bituminous concrete waste material from the higher end (charging aperture) of cylinder, because the inclination and the rotation of cylinder, these fragments are constantly upset and move to lower end (discharging opening) in tube.In moving, be heated softeningly, be stirred the device collision simultaneously, stir and be broken into fritter gradually.On the certain position in cylinder behind one section agitator radially wire lath is set, its mesh is bigger, and the fragment of waste material is passed through; The bulk retaining is continued on cylinder top to stir, heat.The bottom of wire lath, cylinder inner structure are identical with top, and fragment continues to be stirred, fragmentation.This radially wire lath also can repeat to be provided with several layers, and every layer order number increases progressively (being setting from coarse to fine).At the lower end (discharging opening) of cylinder, be one section netted cylinder (being one section tubular wire lath of fixed connection).Fragment is screened at last, pitch with husky, stone separates and the granule that is broken into leaks down by cylindrical net, can heap standby or directly drains on the automobile, entrucking is transported to the building site and uses.

The design has solved the handling problem of bituminous concrete fragment, makes the asphalt-regenerating utilization.Because this device is practical, can be set directly near building site or its, also can fixedly install and be waste disposal factory, can make things convenient for, handle efficiently a large amount of bituminous concrete waste materials, help economizing on resources, and reduced environment pollution.

Now in conjunction with the accompanying drawings embodiment is described further.

Fig. 1 is an example structure schematic diagram;

Fig. 2 is the cross section of Fig. 1;

Fig. 3 is metal mesh structure figure.

With reference to Fig. 1 and Fig. 2, work durm (1) be obliquely installed and link (omitting actuating unit among the figure) with actuating unit.Inwall is provided with agitator, and this agitator is the iron plate (4) that equi-spaced apart is provided with, and every iron plate is all made the setback shape, is fixed with spike post (2) between iron plate (4), both several rows of settings of reporting to the leadship after accomplishing a task.Iron bar cylinder (3) (with reference to Fig. 3) is divided into two parts with cylinder.In first (5), the burned device of the waste material that dog-house is come in (heating arrangements) is heated to the high temperature about 500 ℃, rotation with cylinder constantly is stirred, softens, broken bulk is blocked by iron net (3), continue broken, fine grained chippings enters second portion cylinder (6) by iron net (3), further be stirred (agitator structure in two parts cylinder is identical), under 200 ℃ of left and right sides temperature, continue broken, separation.Second layer iron net (7) is bigger than first floor iron net (3) order number, after particle passes through, mixes in rotation, reverts to the material form of paving the way, and by leaking down in the cylindrical net (8), uses for collecting then.

Claims
