Description
Technical field
The invention belongs to equipment used in asphalt mixing, and in particular to a kind of hot in-plant reclaimed material heating device.
Background technique
The existing generally existing following disadvantage of asphalt-regenerating material heating equipment:
1, conventional single roller hot-mix plant recycling equipment, using high-temperature flue gas reach 1000-1200 DEG C or so burner or
Person generates the hot-blast stove that hot blast temperature is 500-600 DEG C and heats, after this method heated asphalt reworked material, so that generate
Bitumen flue gas is more and ageing of asphalt degree is big, significantly affects the pavement performance of reclaimed asphalt mixture；
2, during heating, pitch can be sticked on barrel conventional single roller hot-mix plant recycling equipment, and be formed viscous
Layer is tied, during laser heating, bulk adhesion material can fall down roller, to influence the gradation of reworked material, and on barrel
Viscous bitumen will increase cost of equipment maintenance.
To solve the above problems, to disclose a kind of continous way regeneration asphalt mixed for the patent that notification number is CN 103088743A
Material mixing plant is closed, workflow is as follows:
As shown in Figure 1, primary aggregate enters inner roller 31 by feed chute 6, in the rotation of inner roller 31 and spiral charging
Under the action of blade enter inner roller 31 heat exchange zone, primary aggregate containing material blade, lifting blade under the action of be elevated,
It leaves, carry out sufficient heat exchange with the high-temperature flue gas that burner 4 generates, and to movement at material-dropping hole 311 in roller；Simultaneously
It is sent into inner roller 31 after reworked material after the recovery is broken by belt conveyor 7, in the rotation of inner roller 31 and screw unloading
Material cavity 36 is fallen into from material-dropping hole 311 under the action of blade, the primary aggregate, high-temperature flue gas after heating are also together through material-dropping hole
311 enter material cavity 36；The primary aggregate of reworked material a part and high temperature into material cavity 36 carries out heat exchange, a part
Heat exchange is carried out with high-temperature flue gas, to improve own temperature；Primary aggregate and recycled aggregate are in the first mixture paddle simultaneously
Piece, the effect of the second mixture stirring blade be lower to carry out premixing, pre- spice by screw unloading blade by discharging end plate 35 again
Raw material discharge port 351 flows out, into continuous mixing host 5, foamed asphalt feed inlet 51, powder which covers
Feed inlet 52 and pre- spice feed inlet 53 are switched according to formula, under the action of continuous mixing host 5, pre- spice and pitch,
Powder fully mixes, and flows out from reclaimed asphalt mixture finished product material discharge port 54.
But there are still following problems when drying regeneration asphalt for the continous way reclaimed asphalt mixture mixing plant:

Discharge end, material temperature is high, exhaust temperature about 180-200 degree；Concurrent heating exhaust temperature is higher, asks there are energy utilization rate is not high
Topic, and will affect the service life of cloth bag；
2, the equipment high temperature flue gas is regenerated by outer roller to exhanst gas outlet by high-temperature flue gas Convective Heating pitch
Material, high-temperature flue-gas are high, however it remains largely ageing of asphalt and the generation of more bitumen flue gas affect regeneration drip
The pavement performance of green mixture；
3, the equipment is using Convective Heating mode heated asphalt reworked material, in the bag filter of exhanst gas outlet connection
Air inducing effect under, add thermogenetic bitumen flue gas so that wind speed is very high in roller with the high-temperature flue gas of flowing heating reworked material
It can be largely inhaled into bag filter with pitch dust, cloth bag is easily caused to block, and when bitumen flue gas and pitch in roller
When dust concentration reaches a certain level, there may be certain security risk；In addition discharge gas can still exist not after dedusting
The case where meeting environmental requirements.
