Description
Technical field
The invention belongs to asphalt production equipment fields, and in particular to a kind of production of continous way action of forced stirring asphalt
Device and method.
Background technique
Asphalt mixture heat regeneration technology is a kind of technology for being recycled waste asphalt mixture, waste asphalt
Mixture be sent into drying heating system carry out drying heat treatment after, then with a certain proportion of new pitch mixture carry out mix.
How much hot recycling equipment yield can design according to the requirement of the maximum adding proportion of waste asphalt mixture.Existing band heat
The asphalt mixing plant of regeneration function is generally divided into intermittent and continous way according to stirring technique point.Intermittent pitch is mixed
Close the technical process for expecting production equipment are as follows: each gradation sand material ingredient conveying, drying is heated, promoted, being sieved, hot aggregate is deposited
Storage, metering (aggregate measuring, powder metering, pitch metering), a mixing bowl stirring, finished product material；Intermittent drip with hot recycling function
The technical process of green mixture production equipment is the technical process in above-mentioned intermittent asphalt mixture production equipment
On the basis of according to reworked material adding proportion require increase reworked material ingredient conveying, promoted, drying heating, hot material storage, hot material
Measure, be delivered to a mixing bowl and new sand material, powder, new pitch etc. stir together, finished product material.Intermittent asphalt mixture stirring
The advantage of equipment is to guarantee that the precision of each gradating material is higher in metering process, stir it is more uniform, but there are still
Following disadvantage: 1, intermittent asphalt mixture production equipment due to need it is intermittent measured, blowing, again measure etc. it is cumbersome
Movement, by cycle influences, equipment yield is relatively low, and plant machinery failure rate is higher；2, existing intermittent pitch mixing
Mixture need to will be sieved back original by screening plant again after the rear drying heating admixed together of different gradation material by material production equipment
The various gradating materials having, not only increase equipment cost, and increase the failure rate of equipment, this repeats the mistake for being blended in separation
Journey also results in the waste of the energy；3, the mixture after heating can be led in the process of large volume of screening and the storage of hot storage silo
The temperature loss of pyrogenicity aggregate results in the waste of the energy to a certain extent；4, the batch type with hot recycling function is set
In standby, also need it is intermittent to hot recycling material measured, blowing, the frequent movement measured again, set by cyclic effects
Standby yield is lower, and herein in frequent cycle movement, since hot recycling material has certain adhesiveness, is easy to cause heat again
Raw material putty during storage, frequent metering of long period etc., influences equipment production and application, will lead to regeneration when serious
The problems such as equipment roller failure, shutdown.
In the prior art, continous way reclaimed asphalt mixture mixing plant is that primary material is passed through internal layer by two-layer cylinder
Roller enters outer layer roller after carrying out drying heating, and reworked material is added in outer layer roller simultaneously and carries out premixing together, finally
Former regenerating mixture is subjected to secondary agitation, such mode disadvantage together are as follows: 1, regeneration cold burden mixed with the new aggregate heated
Afterwards, for reworked material in temperature-rise period, reworked material surface asphalt adhesion is strong, causes outer layer roller to block, easily so as to cause rolling
Cylinder failure, eventually leading to equipment can not normally produce；2, when regeneration adding proportion is more demanding, the temperature of reworked material is in short-term
It is interior only final finished product material temperature to be made to reach requirement by mix with primary hot aggregate.
