Abstract
The utility model discloses a fast dryer for a macroporous core sample on an asphalt pavement for drainage. The fast dryer comprises a drying chamber (1), a vacuum pump (2), a control valve (4) and a condensing chamber (3), wherein the drying chamber (1) is used for holding the core sample to be dried, and a heating device is arranged in the drying chamber; the vacuum pump (2) is used for vacuumizing the drying chamber (1) and connected with the drying chamber (1) through a pipeline; the control valve (4) is arranged on the pipeline connecting the vacuum pump (2) with the drying chamber (1); and the condensing chamber (3) is connected with the vacuum pump (2)via a pipeline. The dryer provided by the utility model can quickly dry the common core sample on the asphalt pavement within ten minutes in the normal temperature, and ensure that the asphalt core sample can not be deformed, thereby greatly saving the waiting time for quality detection of compactness, achieving high drying efficiency and ensuring the reliability of detection results.
Description
Technical field
The utility model relates to a kind of drying equipment, relates in particular to a kind of drying instrument that is used for the big space core on drainage asphalt road surface.
Background technology
It is density measurement and then the key means that calculates compactness and voidage that bituminous paving bores core, but cause moisture to enter core because bituminous paving is unbearable, the test of core dry mass must take means to make moisture evaporation clean, otherwise, the core that contains moisture causes that the density of testing is big, compactness is bigger than normal, causes the quality evaluation error.
At present, core moisture processing method commonly used has two kinds: first natural drying, and this is one of conventional means on the building site, but efficient is very low, even under ventilation, bright day gas condition, also need to wait at least the time of a couple of days usually; It two is that core is put into flash baking in the baking oven, but common asphalt time when being heated to 50～60 ℃, because factor such as pitch is softening, marked change will take place mixture gap rate index, and dissimilar compound Changing Pattern differs greatly.Therefore, oven temperature can not be too high condition under, even add air blast, effect is also very nearly the same with natural drying efficient, particularly to existing the more time of big voidage, suction all the more so, and this performance of compactness deficiency often.
Summary of the invention
The purpose of this utility model is exactly to handle the problem that exists in order to overcome above-mentioned prior art core moisture, a kind of big space core rapid draing instrument that is used for the drainage asphalt road surface is provided, this drying instrument can be at normal temperatures bores common bituminous paving the flash baking of core test specimen in ten minutes, and guarantee that pitch core test specimen any distortion can not take place, significantly saved the stand-by period of compactness quality testing, the drying efficiency height has more guaranteed the reliability of testing result.
For realizing the purpose of this utility model, provide following technical scheme:
A kind of big space core rapid draing instrument that is used for the drainage asphalt road surface comprises: be used to place the hothouse of core to be dried, be provided with heater in it; Be used for evacuated vavuum pump in the hothouse is linked to each other with hothouse by pipeline.
Wherein, the pipeline of described vavuum pump of connection and hothouse is provided with control valve.
In addition, also comprise condensation chamber, be connected with described vavuum pump by pipeline.
Wherein, the pipeline of described condensation chamber of connection and vavuum pump is provided with control valve.
Particularly, be provided with semiconductor cooling device in the condensation chamber.
The beneficial effects of the utility model embody in the following areas:
1, heater is set in hothouse, adopts vavuum pump to be evacuated in the hothouse in the time of heating, quickened the evaporation of moisture in the core, shortened drying time and made core can not deform, thereby guaranteed the accuracy of density measurement;
2, can once carry out the oven dry of a plurality of test specimens, further improve drying efficiency;
3, the device structure simplicity of design is reliable, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of big space core rapid draing instrument of the present utility model.
Description of reference numerals: 1-hothouse; The 2-vavuum pump; The 3-condensation chamber; 4,5-control valve.
The specific embodiment
Shown in the structural representation of Fig. 1 big space core rapid draing instrument of the present utility model, big space core rapid draing instrument of the present utility model comprises hothouse 1, be used to place big space core to be dried, be provided with the heater (not shown) in the hothouse, be used for the core in the hothouse is heated; Vavuum pump 2 links to each other with hothouse 1 by pipeline, so that will be evacuated in the hothouse.
The pipeline that connects vavuum pump 2 and hothouse 1 is provided with control valve 4.
Big space core rapid draing instrument of the present utility model also comprises condensation chamber 3, and condensation chamber 3 is connected with vavuum pump 2 by pipeline.
The pipeline that connects vavuum pump 2 and condensation chamber 3 is provided with control valve 5.
Wherein, be provided with the semiconductor cooling device (not shown) in the condensation chamber 3.
When needs carry out drying to core, core to be dried is positioned in the hothouse 1, and with hothouse 1 sealing, open control valve 4, start the heater in the hothouse 1 when opening vavuum pump 2, make vavuum pump 2 that evacuated while heater in the hothouse 1 is heated core, so that quicken the evaporation of moisture in the core, core can flash baking, and core any distortion can not take place.
After a period of time, close heater, closed control valve 4, opening controlling valve 5, the air that vavuum pump 2 extracts enters condensation chamber 3, and the condensation in condensation chamber 3 of airborne steam changes into water droplet, and dry gas is discharged by vavuum pump.Can take out core this moment in hothouse, the moisture in the core is measured, and do not reach preassigned as moisture, core can be positioned in the hothouse 1 and dry once more, and the content of moisture reaches predetermined requirement in core.
Big space core rapid draing instrument of the present utility model once can be dried a plurality of cores simultaneously, and the time of first drying is short, accelerated drying rate greatly, improved drying efficiency, the change of any distortion and composition characteristic can not take place in the core test specimen in drying course, thereby has guaranteed the accuracy of density measurement.
Although above the utility model has been done detailed description; but the utility model is not limited thereto; those skilled in the art can make amendment according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
