Guarantee that axial force suffered by agitating shaft is smaller, to extend the service life of blender；In addition, the flow velocity by control valve is realized
Mixture it is without interruption, be further ensured that construction quality and meet continuous construction requirement.
Detailed description of the invention
Detailed description of the invention of the invention is as follows:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is that mixture flow of the invention moves schematic diagram.
Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing, but the present invention does not limit to
In these embodiments, any improvement or substitution on the present embodiment essence spirit still falls within the claims in the present invention and is wanted
Seek the range of protection.
Embodiment 1: as shown in Figure 1, 2, a kind of multicomponent high viscosity material containing sand material mixing continuous mixer, the stirring
Machine includes upper end with feed inlet 1, and lower end has the cylindrical agitator tank 3 of discharge port 2, is vertically arranged in the agitator tank 3
There is second level agitating device, the upper end of the second level agitating device is stretched out agitator tank 3 and passed with the power that 3 top of agitator tank is arranged in
Dynamic device 4 connects.
Wherein, the second level agitating device includes agitating shaft 5, the upper and lower part of the agitating shaft 5 be provided with to
Few one group of stirring blade combination.
In order to form second level stirring, so that mixing quality is more preferable, being horizontally disposed in the agitator tank 3 has band to cross material mouth 8
Partition 9, the agitator tank 3 is divided into upper stir chamber 10 and lower stir chamber 11 by the partition 9, described to be located on agitating shaft 5
The stirring blade combination in portion is located in upper stir chamber 10, and the stirring blade combination positioned at 5 lower part of agitating shaft is located at lower stir chamber 11
It is interior.
It further describes, the stirring blade combination includes left-handed stirring blade 6 and dextrorotation stirring blade 7, described left-handed
Stirring blade 6 and dextrorotation stirring blade 7 are symmetrical arranged around agitating shaft 5, have phase angle a between the two；The left-handed stirring blade 6
It is mutually staggered with dextrorotation stirring blade 7 along 5 axis direction of agitating shaft and there is spacing.
For the ease of controlling the speed of material, control valve A12 is respectively arranged at the discharge port 2 and excessively at material mouth 8
With control valve B13.
Further, the top and middle part of the agitating shaft 5 pass through respectively is arranged at the top of agitator tank 3 on upper and partition 9
First support shaft 14 and the second support shaft 15 connect support with agitator tank 3 and partition 9.
Continuous in order to meet discharging process, the control valve A12 discharging speed is v1, control valve B13 discharging speed is v2,
5 mixing speed of agitating shaft is v3, meet v1≤1/v2+1/v3。
In the present invention, actuating unit can be motor, the power-equipments such as engine.
The present invention operates in such a way: upper agitator tank 3 is added from feed inlet 1 respectively in each component heavy viscous material, to height
Viscosity mixture can start actuating unit 4 after not having one group of stirring blade, and agitating device 5 is driven to rotate.It is stirred
When, left-handed stirring blade 6 pushes high viscosity mixture to be rotated in the counterclockwise direction and flow up in upper stir chamber 10, when this height
After viscosity partial blend is pushed to certain altitude, and then dextrorotation stirring blade 7 acts on the part high viscosity mixture,
High viscosity mixture is pushed to move downward rapidly, while further urged clockwise high viscosity mixture.On the whole, high viscosity
Mixture continuously does circular motion and moves up and down simultaneously in upper agitator tank 3, and two kinds of sports reinforcements high viscosity is mixed
The impact between stream and kneading action are closed, to ensure that the mixing quality of high viscous material.Stirring finishes, and opens control valve
B13 and control valve A12 start to be fed, and since inlet valve A12 feeding speed is smaller, carry out so that with whipping process, lower stirring
10 inside material stock of chamber can gradually increase.Therefore, the agitating device inside lower stir chamber 10 can prevent from having stirred the mixing of completion
Material occurs precipitating or isolate.Meanwhile as long as guaranteeing that control valve A12 discharging speed is v1, control valve B13 discharging speed is v2, stirring
5 mixing speed of axis is v3, meet v1≤1/v2+1/v3, that is, can guarantee continuous feeding.
