Abstract
The utility model relates to a temperature-controlled flowing water cycle testing device by a water-boiling method. The device is characterized by comprising a semi-sealed groove, a frequency change micro motor, a turbine, a heater, a temperature sensor, a temperature control device, porous filter plates and suspending platforms, wherein the porous filter plates are installed in the semi-sealed groove, one side of the frequency change micro motor is connected with a power supply while the other side of the frequency change micro motor is connected with the turbine, and the heater and the temperature sensor are connected with the temperature control device; the suspending platforms are placed in the middle of the semi-sealed groove, the porous filter plates are detachable, and the aperture of filter holes is 0.1-0.3 mm. The device provided by the utility model can simulate an actual scene and quantitatively analyze adhesion of asphalt and aggregates by flowing water cycle and temperature control for micro boiling. The testing device is simple in structure, simple in operating method and applicable to indoor tests and field tests.
Description
Technical field
The utility model relates to pitch and gathers materials adhesiveness test, relates in particular to the moving water circulation water-boiling method test unit of temperature control.
Background technology
Bituminous pavement is under the effect of water or freeze thawing circulation, due to the effect of automotive wheel dynamic loads, enter water in space, road surface and constantly produce the iterative cycles effect of pressure or negative pressure of vacuum suction, moisture infiltrates on pitch and the interface that gathers materials gradually, asphalt adhesion is reduced and lose gradually cohesive force, asphalt membrane comes off (peeling off) from building stones surface, and asphalt falls grain, loose, then form bituminous pavement hole groove, push the damage of distortion etc.Pitch is adhered in sex process with gathering materials evaluating water, water-boiling method is because its method of operating is simple and can test fast at the scene and be used widely in pitch and the adhesiveness test of gathering materials.But " micro-boiling " state requiring due to water-boiling method is difficult to control, and the personal error of artificially observing qualitative evaluation adhesion grade bring is larger, makes simple and quick water-boiling method cannot accurately be applied to scientific research.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of and on-the-spot actual test unit contacting of setting up and comes quantitative evaluation pitch and the adhesiveness of gathering materials.
For addressing the above problem, water circulation water-boiling method test unit is moved in temperature control described in the utility model, it is characterized in that: this device comprises semiclosed groove, frequency conversion micromotor, turbine, well heater, temperature sensor, attemperating unit, porous filter plate and suspension platform; Described semiclosed groove is provided with described porous filter plate; One side of described frequency conversion micromotor is connected with power supply, and its opposite side is connected with described turbine; Described well heater, temperature sensor are all connected with described attemperating unit; Described suspension platform is positioned in the middle of described semiclosed groove.
Described porous filter plate is dismountable.
In described porous filter plate, filter opening aperture is 0.1mm to 0.3mm.
The utility model compared with prior art has the following advantages.
1, owing to being provided with well heater, temperature sensor and attemperating unit in the utility model, can manual control " micro-boiling " state under different atmospheric pressure, accurately experiment.
2, because the utility model adopts moving water circulation, the actual moving water of simulated field washes away pitch and the adhering impact of gathering materials, and adjustable frequency motor also can be simulated different moving water flow velocities, contacts with on-the-spot actual foundation.
3, the utility model is under moving water circulation, flake-off and be free in water medium pitch, and flake-off but be still suspended on the pitch of building stones lower end because of molecular force between pitch, capital sticks on porous filter plate with current, prevent that test specimen " secondary pollution " and each test specimen are separate between filter plate, be independent of each other.After having tested, only need to remove filter and clean.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-semiclosed groove 2-frequency conversion micromotor, 3-turbine, 4-well heater, 5-temperature sensor, 6-attemperating unit, 7-porous filter plate, 8-suspension platform.
Embodiment
As shown in Figure 1, water circulation water-boiling method test unit is moved in temperature control, it is characterized in that: this device comprises semiclosed groove 1, frequency conversion micromotor 2, turbine 3, well heater 4, temperature sensor 5, attemperating unit 6, porous filter plate 7 and suspension platform 8; Described semiclosed groove 1 is provided with described porous filter plate 7; One side of described frequency conversion micromotor 2 is connected with power supply, and its opposite side is connected with described turbine 3; Described well heater 4, temperature sensor 5 are all connected with described attemperating unit 6; Described suspension platform 8 is positioned in the middle of described semiclosed groove 1.
Wherein, described porous filter plate 7 is dismountable; In described porous filter plate 7, filter opening aperture is 0.1mm to 0.3mm.
When use, semiclosed the utility model groove 1 is placed on experiment table, frequency conversion micromotor 2 switches on power, drive water circulation by turbine 3, regulate attemperating unit 6 to " micro-boiling " state, test specimen is suspended on respectively on suspension platform 8 and is placed between two porous filter plates 7, after 3min, take off test specimen, removed porous filter plate 7 and cleaned, air-dry its mass loss of rear survey of test specimen.
