Abstract
The present invention provides a kind of laboratory concrete stirring means and mixer, mixer used in this method is its top feed, the twin-shaft mixer of bottom discharge, and mixer is equipped with variable-frequency motor, when using, first by mixer its top feed, after charging, its top feed mouthful is closed, starts mixer, regulation variable-frequency motor rotating speed to setting speed is stirred to concrete, until stirring is completed, after the completion of stirring, by mixer bottom discharge.To solve in existing concrete experiment aggregate weighing, once the scale weighed goes wrong, especially problem occurs for precision, it is impossible to find in time, can cause the problems such as entirely experiment loses researching value.The invention belongs to concrete test research field.
Description
Technical field
The present invention relates to a kind of concrete test mixer and stirring means, belong to concrete test research field.
Background technology
At present, the concrete stirring actual with mixing plant scene of the concrete stirring in laboratory concrete stirring research exists
Mixer agitating mode, feeds discharge method, and cleaning way or view mode are differed, and this allows for the coagulation in laboratory
Native achievement in research is not usually inconsistent with actual use situation, and most laboratory research achievement does not possess its due actual use valency
Value, and for the research of actual production problem, it also usually has relatively large deviation with actual conditions, meanwhile, current laboratory coagulation
During soil stirring, blade and the interaction of mixer inwall easily smash stone, influence concrete quality, and mixer capacity is small,
Generally 60L, maximum is no more than 100L.
The content of the invention
It is an object of the invention to：A kind of laboratory concrete stirring means and mixer are provided, to solve existing coagulation
During soil experiment aggregate is weighed, once the scale weighed goes wrong, especially problem occurs for precision, it is impossible to finds, can cause in time
The problems such as whole experiment loses researching value.
To solve the above problems, intending using such a laboratory concrete stirring means, specific method is as follows：
Mixer used in this method is its top feed, the twin-shaft mixer of bottom discharge, and mixer is equipped with variable-frequency motor,
In use, first by mixer its top feed, after charging, close its top feed mouthful, start mixer, regulation variable-frequency motor rotating speed to
Setting speed is stirred to concrete, until stirring is completed, after the completion of stirring, by mixer bottom discharge.
In preceding method, using the mixer, to multigroup with when total amount phase by way of adjusting variable-frequency motor rotating speed
Same concrete material is stirred respectively with various rotating speed, to study influence of the mixer mixing speed to concrete quality；
In the different phase of same group of concrete material stirring, adjust variable-frequency motor rotating speed, then with raw material and condition all same, but
It is compared with the control group that single mixing speed is stirred, to study the different phase of concrete stirring, mixing speed is to coagulation
The influence of soil property amount；
The present invention also provides a kind of laboratory concrete mixer, and the mixer is twin-shaft mixer, mixer dischargeable capacity
225L, discharge volume 150L, and the motor of mixer is to be respectively arranged with and can beat at the top and bottom of variable-frequency motor, mixer
The charging aperture and discharging opening of open type.
In foregoing mixer, the bottom of mixer is provided with support, and the side of mixer is additionally provided with observation platform, and correspondingly
The side of the mixer of observation platform is provided with observation window.
Compared with prior art, the present invention has following advantage compared with prior art：
1. the agitating mode of the present invention uses variable-frequency motor, speed of agitator can be adjusted, so as to study mixing speed to mixed
The influence of solidifying soil property amount, including same concrete stir influence of the different phase mixing speed to concrete quality；
2. simulating agitating mode, input and output material mode and the view mode of mixing plant, the actual stirring feelings of mixing plant are simulated as far as possible
Condition, it is to avoid experimental study loses contact with reality production, it is ensured that the feasibility and practicality of achievement in research, to problem found in generation
Research also can more fit reality, timely solving practical problems；
3. horizontal-type biaxial stirring, which can be prevented effectively from, smashes stone, it is ensured that concrete quality.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the dimensional structure diagram of mixer；
Fig. 3 is the positive structure schematic of mixer.

With bottom be respectively arranged with can opening type charging aperture 12 and discharging opening 13, the bottom of mixer 1 is provided with support 2, mixer 1
Side be additionally provided with observation platform 3, and the side of the mixer 1 of correspondence observation platform 3 is provided with observation window 14.
Its stirring means is as follows：
Mixer used in this method is its top feed, the twin-shaft mixer of bottom discharge, and mixer is equipped with variable-frequency motor,
In use, first by mixer its top feed, after charging, close its top feed mouthful, start mixer, regulation variable-frequency motor rotating speed to
Setting speed is stirred to concrete, to multigroup with when total amount identical coagulation by way of adjusting variable-frequency motor rotating speed
Native raw material is stirred respectively with various rotating speed, to study influence of the mixer mixing speed to concrete quality；Meanwhile, also may be used
In the different phase of same group of concrete material stirring, adjust variable-frequency motor rotating speed, then with raw material and condition all same, but with list
The control group of one mixing speed stirring is compared, and to study the different phase of concrete stirring, mixing speed is to coagulation soil property
The influence of amount, after the completion of stirring, by mixer bottom discharge.
