Abstract
The utility model discloses a crushing system for asphalt mixture. The crushing system comprises a hopper, wherein a discharge port of the hopper is provided with a horizontally-arranged belt conveyor, a slantwise dust screen is arranged under a discharge end of the belt conveyor, a first crusher for crushing coarse material is arranged under the lower edge of the dust screen, an outlet of the first crusher is provided with a first conveyor, a first vibrating screen is arranged under the discharge end of the first conveyor, a second crusher for crushing fine material is arranged under the first vibrating screen, an outlet of the second crusher is provided with a second conveyor, and a second vibrating screen is arranged under the discharge end of the second conveyor. The crushing system for the asphalt mixture has the functions of multi-stage crushing and screening, so that the identity of the mixture can be improved, and the crushing system is simple in structure, reasonable to design, and very good in practical applicability.
Description
Technical field
The utility model relates to a kind of crushing system, is specifically related to a kind of thermal-regeneration crushing system for waste asphalt mixtures.
Background technology
The highway in China construction is rapid, the high-grade highway total kilometrage that is open to traffic has leapt to the second place of the world, because the comprehensive function of traffic loading and natural cause, bituminous paving is through the use of certain time limit, its surface layer is attenuation and aging gradually slowly, can occur such as check crack, depression, rut, gather around various diseases and the progressively expansion such as bag, have a strong impact on driving.But be that asphalt concrete pavement just need to be overhauled once about 10 years the service life of bitumen concrete highway generally speaking.The method of in the past safeguard processing is exactly that milling is carried out on the road surface that disease occurs, then making again.Can cause like this three large problems: the one, stack occupied ground; The 2nd, wasted a large amount of non-renewable petroleum resources, required a large amount of pitches and the building stones of making asphalt concrete pavement will make us face huge resource pressure again; The 3rd, destroy ecological environment.
Because it is extremely huge that highway is overhauled the annual waste asphalt concrete quantity that produces, if effectively recycling will cause huge pressure and destruction to environmental protection.
At present, the bitumen concrete highway is overhauled the waste asphalt concrete that produces, the hot regeneration techniques of main employing recycles, but existing technology only can realize the one-level screening, produces two kinds of specification material after the screening: material up to specification and ultra-specification rejected material, in the material up to specification, be mingled with the impurity such as dust, the homogeneity of the stylish compound of heat regeneration is poor, and affects the quality of reclaimed asphalt mixture.
The utility model content
The purpose of this utility model is to provide a kind of asphalt crushing system, and described asphalt crushing system has multiple stage crushing and screening, has improved the homogeneity of compound.
For achieving the above object, the technical solution of the utility model is a kind of asphalt crushing system of design, comprise hopper, the discharging opening of hopper is furnished with the belt feeder of horizontal, belt feeder discharge end below is provided with tilting dust sieve, the below of dust sieve lower edge is provided with the first disintegrating machine for broken coarse fodder, the outlet of the first disintegrating machine is furnished with the first conveyer, the first conveyer discharge end below is provided with the first vibratory sieve, the below of the first vibratory sieve is provided with the second disintegrating machine for broken fines, the outlet of the second disintegrating machine is furnished with second conveyor, and second conveyor discharge end below is provided with the second vibratory sieve.
Preferably, the sieve screen apertures order of described the first vibratory sieve is of a size of 25mm.
Preferably, the sieve screen apertures order of described the second vibratory sieve is of a size of 10mm.
Preferably, described dust sieve under also be provided with dust collecting box.
Preferably, be provided with agitator in the described hopper.
By the discharging direction at the hopper of crushing system the dust sieve is set, can in advance the dust in the waste asphalt mixture be screened out, and the vibratory sieve that adopts two gradation sizings, improved the homogeneity of compound, improve the quality of thermal regeneration bitumen material; Reduce heat dust material bonding in the process of the old material of hot reclaim equiment, improve the service behaviour of hot reclaim equiment.
Advantage of the present utility model and beneficial effect are: a kind of asphalt crushing system is provided, and described asphalt crushing system has multiple stage crushing and screening, has improved the homogeneity of compound, and simple in structure, reasonable in design, has good practicality.
