And regenerative system.
Background technology
Required with regard to " building a conservation-minded society ", " developing a circular economy " etc. to respond country in recent years, along with stone
Oil, the rise of the resource price of building stones, all positive the taking action of various places highway division, with " sustainable development " as objective, with
Development " green traffic " is target, and the recycling of old road asphalt material retrieves attention and pays close attention to.
Waste asphalt mixture broken be old road asphalt material recovery technique important step, specially by waste and old road
Big particle diameter (generally higher than 40mm) Particle Breakage of the ultra-specification in the waste asphalt that face recovery comes becomes the small particle of below 40mm
Particle.Existing unit can be entered to the big size particle materials of ultra-specification in waste asphalt with impact breaker using jaw crusher
Row is broken, and jaw crusher is widely used in mine field, and it is applied and can be caught broken stone (coarse aggregate) in waste asphalt crushes,
The original level destroying waste asphalt is joined.Impact breaker is higher due to the speed of mainshaft, applies and hits in waste asphalt crushes
Block and buffer board abrasion meeting ratio are very fast, also can smash stone, the original level destroying waste asphalt is joined simultaneously.Above-mentioned disintegrating machine is
Carried out broken by way of extruding or tapping, and waste asphalt is to be bonded in the building stones of all size by the pitch of viscosity
Together, extrude or tap viscosity limited use to pitch, the low degree being therefore broken it is impossible to reach the technology that level joins will
Ask.

Specific embodiment
The utility model is further described it should explanation is, the description below is merely to solve in conjunction with the embodiments
Release the utility model, its content is not defined.
As shown in figure 1, a kind of waste asphalt breaker roll, including rotating cylinder 2 and several cutting structures, cut structure
Two ends are cutting teeth 4, and middle is connecting portion, and each cutting structure rotates cylinder 2 substantially along rotating extending radially through of cylinder 2,
Make connecting portion in the inside rotating cylinder 2, the cutting teeth 4 at two ends all extends the outer wall rotating cylinder 2;Cutting teeth 4 with turn
It is provided with the fixed seat that cutting structure is fixed, fixed seat is removably solid by cutting teeth 4 between the outer wall of dynamic cylinder 2
It is scheduled on rotation cylinder 2.
Described cutting teeth 4 cross-distribution on rotating cylinder 2, rotates cylinder 2 generally cylindrical.The reason cross-distribution
To intercept bulk materials positioned at two cutting teeths 4 rotating on cylinder 2, another rotate on cylinder 2 positioned at this two
Cutting teeth 4 between cutting teeth 4 cuts to bulk materials, and the bus that cutting teeth 4 is arranged with respect to rotate cylinder 2 inclines
Tiltedly arrange, during rotating cylinder 2 rotation, bulk materials are produced used by tear, destroy between aggregate and pitch
Active force, makes bulk materials crush, and avoids simultaneously and applies extruding force it is ensured that the integrity degree of aggregate to aggregate.Cutting teeth 4
Angle of inclination be 12-17 degree, more preferably 15 degree, when angle of inclination for 15 degree when, tear crushing effect can be made more
Good.
The thickness of cutting teeth 4 is 25-30mm, and the spacing between two neighboring cutting teeth is 150-250mm.Between cutting teeth
Away from can according to live degree of crushing require be adjusted.
As shown in Figures 2 and 3, a kind of waste asphalt fragmentation cell, including two described breaker rolls and base plate 3, two are broken
Broken roller includes the first breaker roll and the second breaker roll 6, and two breaker rolls coordinate installation side by side, and two breaker rolls are respectively with first

18 connections, air inducing, so that heating medium is entered in the interior cartridge heater 3 of heating stirrer 18, obtain mixed material.Mixed material is through adding
The outlet of thermal agitation device 18 is flowed out, and is temporarily stored in surge bunker 20.The lower section setting compound belt of surge bunker 20
Weigher 21 and new pitch belt weigher 22, if construction ground needs to add new pitch in the reworked material of waste asphalt,
Compound belt weigher 21 weighs to the compound obtaining, and new pitch belt weigher 22 weighs to new pitch,
After mixed material is mixed by a certain percentage with new pitch, obtain Recycled Asphalt Pavement, regeneration asphalt is used for reality
In engineering.
From said process, the sieve that shaken of the thinner dust except obtaining in crushing process 14 screens out, other useless
Bituminous concrete surface all can be obtained by by regeneration, substantially increases the utilization rate of waste asphalt.
Although the above-mentioned accompanying drawing that combines is described to specific embodiment of the present utility model, not to utility model
The restriction of protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, this area
Technical staff does not need to pay the various modifications that creative work can make or deformation still in protection domain of the present utility model
Interior.
