It causes.Relative to existing hot adding technique, the cold addition regeneration asphalt concrete plant mix equipment of the multistage subsection mix of the embodiment of the present invention
Have the advantages that structure is simple, production cost is low, low energy consumption and product quality is high.
Correspondingly, the present invention also provides a kind of cold addition regeneration drips of multistage subsection mix corresponding with above-described embodiment
Qing Tong plantmix method, the cold addition regeneration asphalt concrete plantmix method of multistage subsection mix the following steps are included:
Step a, using hot material scale 20 and cold additive scale 30 respectively to the rubble and unheated Bituminous concrete surface concrete after heating
It is weighed；
Rubble temperature is higher after heating, therefore releasable a large amount of heat, the initial temperature of the present embodiment medium stone are higher than
220 DEG C, and Bituminous concrete surface concrete is heated due to not needing, and does not need to increase a series of equipment such as regeneration roller, and life is effectively reduced
Produce cost.Raw material needs respectively to weigh rubble and Bituminous concrete surface concrete before entering mix cylinder 40, it is ensured that rubble and old
Bitumen concrete enters according to a certain percentage in a mix cylinder 40, and Bituminous concrete surface concrete amount is avoided excessively to influence the quality of finished product.
Step b imports rubble and Bituminous concrete surface concrete in mix cylinder, and pitch is added and carries out a mix, rubble with
Pitch forms new pitch concrete；
Rubble and Bituminous concrete surface concrete, which enter in a mix cylinder 40, carries out a mix, and rubble and Bituminous concrete surface concrete is made to be blended in one
It rises, the heat transfer of rubble release gives Bituminous concrete surface concrete, melts part Bituminous concrete surface concrete.Pitch is added, rubble is formed with pitch
New pitch concrete.
Step c, by the new pitch concrete and the Bituminous concrete surface concrete importing storage certain time of hot material storage silo 50 after a mix；
Since pitch heat conduction of velocity is slow, the storage time of new pitch concrete and Bituminous concrete surface concrete in hot material storage silo 50
Greater than 15min, during hot material storage silo 50 stores, new pitch concrete and Bituminous concrete surface concrete have longer time of contact, can make big portion
The Bituminous concrete surface concrete divided melts.By by after mix new pitch concrete and Bituminous concrete surface concrete import hot material storage silo 50 storage one timing
Between, the time of contact of new pitch concrete Yu Bituminous concrete surface concrete is extended, the heat for discharging new pitch concrete sufficiently passes to Bituminous concrete surface concrete,
Ensure that Bituminous concrete surface concrete sufficiently melts, further increases the quality of finished product.
New pitch concrete and Bituminous concrete surface concrete are imported in secondary mix cylinder 60 and carry out secondary mix by step d.
New pitch concrete and Bituminous concrete surface concrete pass through secondary mix, and the two mixes more evenly, during mix new pitch concrete by itself
The heat transfer of carrying improves the quality of finished product to the remaining Bituminous concrete surface concrete not melted.
As shown in Fig. 2, in another embodiment of the invention, the cold addition regeneration asphalt concrete plant mix equipment of multistage subsection mix
Including frame body 10, hot material scale 20,30, mix cylinders 40 of cold additive scale, secondary mix cylinder 60 and mix cylinder 70 three times,
In, frame body 10 is the cuboid support body being welded by more angle steel.Due to 30, hot material scale 20, cold additive scale mixs
Cylinder 40, secondary mix cylinder 60 and three times mix cylinder 70 be in the market can firsthand equipment, therefore its specific structure is no longer
It is discussed in detail.Hot material scale 20 and cold additive scale 30 are set to the top of frame body 10, and hot material scale 20 is used for the rubble after heating
It is weighed, cold additive scale 30 is for weighing unheated Bituminous concrete surface concrete, it is ensured that rubble and Bituminous concrete surface concrete are according to one
Certainty ratio enters in a mix cylinder 40.Mix cylinder 40 is set to the lower section of hot material scale 20 and cold additive scale 30, and with
Frame body 10 connects；The feed inlet of mix cylinder 40 connects with the discharge port of the discharge port of hot material scale 20, cold additive scale 30 respectively
It connecing, secondary mix cylinder 60 is set to the lower section of a mix cylinder 40, and mix cylinder 70 is set to the lower section of secondary mix cylinder 60 three times,
Secondary mix cylinder 60 and mix cylinder 70 is connect with frame body 10 three times；The feed inlet of secondary mix cylinder 60 and mix cylinder 40
Discharge port connection, the discharge port of secondary mix cylinder 60 are connect with the feed inlet of mix cylinder 70 three times.In order to ensure the charging of raw material
The discharging speed of speed and finished product is consistent, in the present embodiment, a mix cylinder 40, secondary mix cylinder 60, three times mix cylinder
70 model is all the same.
Correspondingly, the present invention also provides a kind of cold addition regeneration drips of multistage subsection mix corresponding with above-described embodiment
Qing Tong plantmix method, the cold addition regeneration asphalt concrete plantmix method of multistage subsection mix the following steps are included:
Step a, using hot material scale 20 and cold additive scale 30 respectively to the rubble and unheated Bituminous concrete surface concrete after heating
It is weighed；
Rubble temperature after heating is higher, and the initial temperature of the present embodiment medium stone is higher than 220 DEG C, and Bituminous concrete surface concrete due to
It does not need to heat, therefore does not need to increase a series of equipment such as regeneration roller, production cost is effectively reduced.Raw material, which enters, once to be mixed
It needs respectively to weigh rubble and Bituminous concrete surface concrete before closing cylinder 40, it is ensured that rubble and Bituminous concrete surface concrete enter according to a certain percentage
In mix cylinder 40, Bituminous concrete surface concrete amount is avoided excessively to influence the quality of finished product.
Step b imports rubble and Bituminous concrete surface concrete in mix cylinder, and pitch is added and carries out a mix, rubble with
Pitch forms new pitch concrete；
Rubble and Bituminous concrete surface concrete, which enter in a mix cylinder 40, carries out a mix, and rubble and Bituminous concrete surface concrete are blended in one
It rises, the heat transfer of rubble release gives Bituminous concrete surface concrete, melts part Bituminous concrete surface concrete.Pitch is added, rubble is formed with pitch
New pitch concrete.
Step c will carry out secondary mix in the new pitch concrete and the secondary mix cylinder 60 of Bituminous concrete surface concrete importing after a mix；
New pitch concrete and Bituminous concrete surface concrete mix more evenly after carrying out secondary mix, and the heat of new pitch concrete release makes major part
Bituminous concrete surface concrete melts.
Step d, by after secondary mix new pitch concrete and Bituminous concrete surface concrete import and carry out mix three times in mix cylinder 70 three times；
New pitch concrete and Bituminous concrete surface concrete mix more evenly after mix three times, and mix also corresponds to extend newly three times
The time of contact of bitumen concrete and Bituminous concrete surface concrete makes the heat transfer of more new pitch concrete releases give Bituminous concrete surface concrete, it is ensured that Bituminous concrete surface
Concrete sufficiently melts, and further increases the quality of finished product.In order to ensure the charging rate of raw material and the discharging speed of finished product keep one
It causes, a mix, secondary mix and the duration of mixing of mix is equal three times.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
