Abstract
The invention discloses a kind of old asphalt mixture Pneumatic type flexible crusher, including control device, high-pressure air feed device, drawing-in device and frame；High-pressure air feed device and drawing-in device are installed in frame；Control device is arranged on high-pressure air feed device；High-pressure air feed device includes high-pressure pump and pressure piping；One end of pressure piping is connected on high-pressure pump.With respect to other breakers, because air pressure size is adjustable at any time, and air, as non-rigid medium, can be carried out to old asphalt mixture flexible broken, so that Bituminous concrete surface is peeled off along its interface with building stones, join requirement with the regenerative meeting Colophonium the present invention.
Description
Technical field
The invention belongs to engineering machinery field, particularly to a kind of old asphalt mixture Pneumatic type flexible crusher.
Background technology
Bituminous paving is the main Types of China's road, and asphalt is as road surface structare layer, its asphalt performance meeting
Decay with the growth of service life and lead to Pavement Performance to reduce.Use can not be met when Pavement Performance declines to a certain extent
During requirement, need to carry out pavement recapping or reconstruction, thus producing substantial amounts of old asphalt mixture.With people to sustainable development
And the concern of environmental protection problem, the regeneration problem of waste asphalt mixture becomes focus.
Current regeneration technology mainly has in-place regeneration method and plant-mix recycling method.Regardless of whether adopted which kind of method, crush dress
Putting is the indispensable equipment of waste asphalt mixture recycling.Conventional crumbling method is mainly dependence extruding or impacts
Realize broken, the mode of this " hard-hard " easily squeezes the coarse aggregate inside broken old asphalt mixture, thus destroying original level
Join, reduce regeneration and be worth.For this reason, do not destroy coarse aggregate old asphalt mixture flexibility breaking method and equipment have very heavy
The meaning wanted.
Content of the invention
It is an object of the invention to provide a kind of old asphalt mixture Pneumatic type flexible crusher, to solve prior art
In the presence of problem；Old asphalt mixture in the present invention is to realize old asphalt mixture by way of high pressure draught impacts
Broken, the cutting force of this high pressure breaker air knife is higher than adhesive strength between aggregate, is but less than aggregate self-strength, because
This, in shattering process, while ensureing crushing efficiency, it is to avoid aggregate broken.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of old asphalt mixture Pneumatic type flexible crusher, including control device, high-pressure air feed device, feeding dress
Put, high pressure breaker and frame；High-pressure air feed device and drawing-in device are installed in frame；Control device is arranged on high pressure
On feeder；
High-pressure air feed device includes high-pressure pump and pressure piping；One end of pressure piping is connected on high-pressure pump；High-voltage tube
The other end in road connects high pressure breaker；
Drawing-in device includes support and skewed slot；Support is arranged in frame, and support is provided with skewed slot；Drawing-in device oblique
Groove end is provided with the base plate of level；There is gap between drawing-in device and base plate.
Further, the gap between drawing-in device and base plate is used for the aggregate by being broken.
Further, control device includes sensor, pressure regulator valve, gas switch and pressure gauge；Pressure regulator valve, gas switch and
Pressure gauge is installed on pressure piping；Sensor is arranged on the end of drawing-in device.
Further, high pressure breaker includes several nozzles.
Further, high pressure breaker is located at the surface in the gap between drawing-in device and base plate.
Compared to prior art, the present invention has following technology effect：
, with respect to other breakers, because air pressure size is adjustable at any time, and air is as non-rigid medium for the present invention,
Old asphalt mixture can be carried out flexible broken, so that Bituminous concrete surface is peeled off along its interface with building stones, to meet Colophonium
Regenerative joins requirement.
The present invention is by high speed and high pressure air-flow, old asphalt mixture to be crushed, pressure size can by control system with
When adjust, easy to operate.
Rationally, structure is simple, good economy performance for the present invention program, can give full play to flexible broken advantage.

Specific embodiment
The specific embodiment of the present invention given below, implements in detail below it should be noted that the invention is not limited in
Example, the equivalents done on the basis of all technical schemes in application each fall within protection scope of the present invention.
Refer to shown in Fig. 1, a kind of old asphalt mixture Pneumatic type flexible crusher, supply including control device, high pressure
Device of air, drawing-in device 2, high pressure breaker and frame 1；High-pressure air feed device and drawing-in device 2 are installed in frame 1；
Control device is arranged on high-pressure air feed device；
High-pressure air feed device includes high-pressure pump 10 and pressure piping 7；One end of pressure piping 7 is connected on high-pressure pump；High
The other end of pressure pipeline 7 connects high pressure breaker；
Drawing-in device 2 includes support and skewed slot；Support is arranged in frame 1, and support is provided with skewed slot.Drawing-in device 2
Skewed slot end be provided with the base plate 8 of level；There is gap between drawing-in device 2 and base plate 8.
Gap between drawing-in device 2 and base plate 8 is used for the aggregate by being broken.
Control device includes sensor 3, pressure regulator valve 9, gas switch 5 and pressure gauge 6；Pressure regulator valve 9, gas switch 5 and pressure
Power table 6 is installed on pressure piping 7；Sensor 3 is arranged on the end of drawing-in device 2.
High pressure breaker includes several nozzles 4.
High pressure breaker is located at the surface in the gap between drawing-in device 2 and base plate 8.
The operation principle of the present invention is as follows：
When broken, old asphalt mixture enters at the gap between base plate 8 and drawing-in device 2 by drawing-in device 2, old
When asphalt presses through sensor 3, material is detected, open high-pressure pump 10 simultaneously, adjust pressure regulator valve 9, gases at high pressure pass through
High-pressure pump 10 enters pressure piping 7, then opens gas switch 5, last gases at high pressure are ejected by high pressure breaker,
Old asphalt mixture is crushed, the gases at high pressure of the ejection gap between drawing-in device 2 and base plate 8 flows away, it is to avoid will
Base plate 8 impact failure；
In aggregate, between aggregate, interface is impacted by gases at high pressure, you can aggregate is implemented separately broken；Satisfaction after broken will
The aggregate grain asked falls from gap, if big aggregate is impacted, gas impulsive force is less than the intensity of aggregate, protects big aggregate not break
Broken, the big aggregate not being broken is stayed on base plate 8, thus realizing flexible broken.
