Description
Technical field:
The present invention relates to a kind of emulsified asphalt measuring technology, the testing tool that specifically a kind of emulsified asphalt can duration of mixing.
Technical background:
Emulsified asphalt can duration of mixing, is an important indicator of mix type emulsified asphalt, often with the length of duration of mixing, evaluates the operable time of slurry mixture in engineering, and according to test moulding situation, qualitatively judges the compatibility quality of compound.
At present, the duration of mixing of mensuration both at home and abroad can to(for) emulsified asphalt, is mainly the experience that relies on testing crew, and test findings is subject to the impact of artificial subjectivity very large, and can accurately can duration of mixing according to the tachometry of standard 60-70r/min.Meanwhile, adopt the mode (similar to spoon mix Emulsified Asphalt Mixture in container) of mix spoon mix, can not simulate well Practical Project mix situation, the conclusion drawing is rough duration of mixing.
Summary of the invention:
A difficult problem that is difficult to Accurate Determining for emulsified asphalt duration of mixing, emulsified asphalt can duration of mixing tester accurately to the invention provides a kind of test result.This instrument not only can Accurate Determining emulsified asphalt can duration of mixing, that can also measure emulsified asphalt simultaneously can not the engineering time.
The concrete technical scheme of this emulsified asphalt duration of mixing tester is:
This tester mainly by bucket, paddle, dynamic torque sensor, controller, data acquisition system (DAS) (torque signal data derive line), connector, rotating shaft, track, motor, be configured to.Paddle, dynamic torque sensor, connector, motor, all link together from bottom to up by rotating shaft, general designation A structure, and A structure is connected with support by track.Controller is positioned on support.A structure can be realized and being moved up and down by track, and capable of regulating paddle rotating speed and adjustment A structure are in track displacement.In support lower end, settle bucket.
Described paddle, is the plane net structure with certain size, has the function that is uniformly mixed material under power system effect;
Described dynamic torque sensor is a kind of precision measurement instrument of measuring moment of torsion, rotating speed and mechanical output; Adopt electric measurement technique of strain gage, on elastic shaft, form strain bridge, to strain bridge, provide power supply can record the electric signal that this elastic shaft is turned round.After this strain signal is amplified, through the conversion of overvoltage/frequency, become and the frequency signal that is twisted into direct ratio;
Described controller, is mainly used in controlling motor speed and A structure moves up and down;
Described data acquisition system (DAS), refers to that torque signal data derive line, and being responsible for derives dynamic torque signal data;
Described connector is a kind of device of adjusting motor speed.
When A structure is during by track decline appropriate location, start stirring power supply, just can in charge Gutter, realize agitating function, now in A structure, dynamic torque sensor just can spread out of moment of torsion data, realizes data analysis.By controller, set rotating speed, motor reaches rotating shaft according to the rotating speed of setting by moment of torsion, rotating shaft is by being connected with connector, dynamic torque sensor, paddle, paddle stirs the Emulsified Asphalt Mixture in material pot, Emulsified Asphalt Mixture reaches dynamic torque sensor by opplied moment in whipping process by rotating shaft, and then draws change in torque situation in whipping process.
Testing procedure and the test philosophy of this tester are as follows:
According to standard ratio by standard grading gather materials, adjuvant etc. first pours in bucket, paddle is dropped to correct position in material pot by track, set after rotating speed, first water (anionic emulsifier does not need to add water) is added to and just mix in gathering materials to evenly, then add again proper proportion emulsified asphalt to material pot, start formal stirring, paddle is by being connected with turning axle, can reach torque sensor by mixing leaf resistance, gather moment of torsion data, torque sensor and then data are reached to computer, m-torque diagram shape while drawing by related software.There is obviously turnover in curve in the drawings, and by the point of intersection of tangents at turnover two ends, i.e. moment of torsion sudden change place is the sign that compound starts breakdown of emulsion, and be can duration of mixing the time this moment.And then can draw Emulsified Asphalt Mixture intensity forming process Changing Pattern by analyzing slope variation, and can better instruct actual production, to on-site construction time, control shop experiment data are accurately provided.
This emulsified asphalt duration of mixing tester advantage:
1, mentality of designing of the present invention is simple, and test result accurately and reliably, has been evaded the harmful effect of human factor in mensuration process.
2, the present invention is by setting paddle rotating speed, and by torque sensor, will mix accurately leaf resistance and reach computer, m-torque diagram during drafting, to analyze emulsified asphalt duration of mixing, can not only meet exactly code requirement, paddle stirs and more can simulate Practical Project situation simultaneously.
3, the present invention can draw Emulsified Asphalt Mixture intensity forming process Changing Pattern by analyzing moment of torsion slope variation situation, to site operation, provides reliable Data support.
4, the present invention not only can measure the duration of mixing of emulsified asphalt, also can measure the duration of mixing of cement admixture; Etc..
5, the present invention also can contrast the moment of torsion of hot-mix asphalt mixture and Warm-Mix Bitumen Mixture, thereby determine the required warm mix temperature of Warm-Mix Bitumen Mixture accurately by setting fixed rotating speed, for warm mix provides reliably, experimental data accurately.
