Description
Technical field
This utility model is related to Colophonium processing technique field, more particularly to a kind of modified pitch premix kettle.
Background technology
With increasing rapidly for highway in China transport development, road transport is increasingly busy.The rut of bituminous paving, cracking,
The diseases such as pit are extremely serious.For the performance for improving bituminous paving comprehensively, it is one of effective measures using modified pitch.Mesh
Before, mainly there are a modified pitch such as SBR, PE, EVA, rubber powder, SBS using more, and SBS is because which is good two-way modified
Performance (changing the ability of the high temperature with cryogenic property of matrix pitch simultaneously) obtains comparing being widely applied in recent years.SBS
Modified pitch is prepared as modifying agent with one styrene block copolymer of styrene-butadiene (i.e. SBS), is passed through
There is Swelling in physical blending process, the aromatic hydrocarbons and colloid in SBS adsorptive pitch, form new colloform texture system, that is, exist
Network structure is formed in Colophonium, the performance of Colophonium is improved comprehensively.
At present, in the mixed process of the modifying agent such as SBS and matrix pitch, its premix degree of being uniformly dispersed can be directly influenced
The process that later stage is modified, as asphalt viscosity is big, is needed modifying agent could be uniformly dispersed by prolonged stirring, is caused
Production cost increases.
Utility model content
The purpose of this utility model is to provide a kind of modified pitch to premix kettle, can shorten modified pitch and do time in advance,
Reduce enterprise's production capacity.
The technical solution adopted in the utility model is：
A kind of modified pitch premixes kettle, including column type and the kettle body with heating interlayer, on the top of the kettle body
Portion is provided with charging aperture, is provided with agitator and agitator is driven with being arranged on the outside of kettle body bottom portion in the bottom of the kettle body
The rotating shaft connection of motor, discharging opening are located on the outside of kettle body bottom portion, it is characterised in that：It is additionally provided with the outside of the kettle body bottom portion
One loop exit, is provided with along the hand of spiral in several circulation imports and the hand of spiral on the kettle body upper side wall
The position of minimum circulation import is higher than agitator work surface position, and several circulate imports with loop exit Jing bitumenpumps and pipe
Road links together.
Further, an independent flow valve is provided with the pipeline being connected with circulation import per root, adjust from each
Circulation circumfluence is to the intrinsic flow rate of asphalt of kettle and flow velocity.
Further, one block of annulus bushing is fixed with below the kettle inner body wall and annulus bushing is located at agitator
Top, the strong shear stirring region of agitator is further reduced, and causes the stirring dynamics in the region to become strong.
Further, the neighbouring position of the annulus bushing and kettle body interior junction is in arc-shaped, and middle part is to downward
Stretching and diameter being tapered into, overall flare shape, the Colophonium Jing annulus bushing for rolling being acted on by agitator stop and then edge
Arc and return to and be stirred at agitator again, raising is uniformly dispersed degree, shortens mixing time.
The beneficial effects of the utility model are：
This utility model architecture is simple, and mixing is stirred by the way of lower stirring, and kettle sheet is stirred below in vivo
The Colophonium mixed in device region is pumped back to zones of different above kettle body by Colophonium, and Colophonium is disturbed, then top area
In domain, Colophonium is fallen through annulus bushing and carry out at agitator strong stirring.When can shorten modified pitch premix using this device
Between, reduce enterprise's production capacity.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order that the advantage of the purpose of this utility model and technical scheme becomes more apparent, below in conjunction with accompanying drawing and reality
Example, is further elaborated to this utility model.
As shown in Figure 1, a kind of modified pitch premixes kettle, including column type and the kettle body 1 with heating interlayer, in institute
The top for stating kettle body 1 is provided with charging aperture 2, be provided with agitator 3 in the bottom of the kettle body 1 and agitator 3 be arranged on
The rotating shaft connection of 1 bottom outside motor 4 of kettle body, discharging opening 5 are located at 1 bottom outside of kettle body, it is characterised in that：Institute
State 1 bottom outside of kettle body and be additionally provided with a loop exit 6, be provided with along the hand of spiral on 1 upper side wall of the kettle body
The position of circulation import 7 minimum in several circulation imports 7 and the hand of spiral is higher than 3 work surface position of agitator, several
Circulation import 7 is linked together with 6 Jing bitumenpumps 8 of loop exit and pipeline.Set on the pipeline being connected with circulation import 7 per root
There is an independent flow valve 9.One block of annulus bushing 10 is fixed with below 1 inwall of kettle body and annulus bushing 10 is located at
The top of agitator 3.The neighbouring position of the annulus bushing 10 and 1 internal connection of kettle body is in arc-shaped, and middle part is to downward
Stretch and diameter is tapered into, overall flare shape.
Operation principle of the present utility model is：
Modifying agent and matrix pitch are added in kettle body 1 from charging aperture 2, are heated and are maintained technological temperature.Start motor
4, agitator 3 is then quick to be rotated, and carries out high speed shear dispersion to the mixture of matrix pitch and modifying agent.Area near agitator 3
In domain, Colophonium receives shear action and rolls up and down, and the Colophonium of rolling is subject to annulus bushing 10 and 1 diapire of kettle body to stop backflow
Mixed at agitator 3.Moreover, 8 the following from various location of part Colophonium Jing bitumenpump in 3 near zone of agitator
Ring import 7 is back to kettle body 1, and the Colophonium on upper strata is disturbed.The Colophonium on upper strata is then entered into through annulus bushing 10 and is stirred
Mixing 3 near zone of device carries out THE ADIABATIC SHEAR IN stirring, until pre-dispersed uniform.
