Abstract
The utility model discloses a mould ware is irritated to experimental accuse temperature of three big indexs of pitch, including cup and digital temperature -controlled box, the cup includes outer wall and inner wall, and the inner wall bottom is provided with heating device and temperature sensor, the numeral temperature -controlled box includes the control unit, and the control unit is connected with heating device and temperature sensor, and the control unit still is connected with switch, intensification switch, cooling switch, accuse temperature display screen and shi wen display screen. Through the internal problem of temperature sensor acquisition cup, pitch sample temperature is controlled to rethread numeral temperature -controlled box, makes pitch keep easily pouring into the state, and convenient quick watering examination mould prevents to heat the pitch sample repeatedly, and it influence the test result to send the ageing of asphalt, and through digital temperature -controlled box, can high temperature heating send pitch and at the trickling state, be convenient for topple over clean and irritate mould ware inner wall residual bitumen, the utility model discloses simple structure, it is novel reasonable to design, makes things convenient for the quick watering examination mould of experimenter, improves the test speed, and the suitability is strong, convenient to popularize and use.
Description
[technical field]
The utility model belongs to pitch three norms test field, is specifically related to a kind of pitch three norms test temperature control and fills with mould device.
[background technology]
The test of pitch three norms comprises asphalt penetration test, bituminous softening-point test, bitumen ductility test, experimentation is equipped with that the sample holder of sample is with cover puts into constant temperature oven, the bitumen samples be baked in sample holder is poured into immediately in the mould of every test, for carrying out the test of pitch three norms, evaluate the temperature sensitivity of bitumen samples, high-temperature stability and crack resistance at low-temperature respectively.
In research and practice process, utility model people of the present utility model finds to fill with in mold process at bitumen samples, and the filling mould difficulty of sample holder is large; be not easy to operation; often can overflow mould trickling on ground, pitch has very high viscosity, is not easy to scrape mould and wiping cleaning.
Fill with in mold process at pitch, sample holder medium pitch specimen temperature declines, and bitumen samples becomes sticky thick very soon, flows out with large discharge, be difficult to fill with mould, modified bitumen is particularly outstanding, again need put into baking oven through heating, just can carry out filling mould, mould could be filled with complete through repeatedly heating, bitumen samples is through the circulation of supercooling and heating, and bitumen samples is easily aging, affects test findings.
[utility model content]
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of pitch three norms to test temperature control and fills with mould device, can control bitumen samples temperature, pitch is made to keep being easy to perfusion state, water die trial easily and fast, prevent heated asphalt sample repeatedly, causing ageing of asphalt affects test findings.
In order to achieve the above object, the utility model comprises cup and digital temperature-controlled box;
Described cup comprises outer wall and inwall, heating arrangement and temperature sensor is provided with bottom inwall, described digital temperature-controlled box comprises control module, control module is connected with heating arrangement and temperature sensor, and control module is also connected with power switch, intensification switch, cooling switch, temperature control display screen and Shi Wen display screen.
The outer wall of described cup is provided with handle.
Described handle outside is coated with one deck plastics.
Described cup offers the filling die orifice be convenient to fluid and poured out.
Described cup is uncovered elliptic cylindrical with the end.
Described digital temperature-controlled box comprises housing, and power switch, intensification switch, cooling switch, temperature control display screen and Shi Wen display screen are all arranged on housing.
Compared with prior art, the utility model can gather the temperature in cup by temperature sensor, bitumen samples temperature is controlled again by digital temperature-controlled box, pitch is made to keep being easy to perfusion state, water die trial easily and fast, prevent heated asphalt sample repeatedly, cause ageing of asphalt and affect test findings, by digital temperature-controlled box, pitch can be caused be in trickling state by high-temperature heating, be convenient to topple over clean and fill with mould device inwall residual bitumen, the utility model structure is simple, design rationally novel, experimenter is facilitated to water die trial fast, improve test speed, applicability is strong, be convenient to promote the use of.
Further, the utility model is provided with high temperature resistant, that coefficient of heat conductivity is little plastic handles, prevents bitumen samples temperature height from scalding experimenter.
Further, the utility model offers filling die orifice, and the pitch after heating can be made to pour out fast.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1 and Fig. 2, the utility model comprises cup and digital temperature-controlled box, cup offers the filling die orifice 1 be convenient to fluid and poured out, and cup is uncovered elliptic cylindrical with the end, cup comprises outer wall 2 and inwall 3, heating arrangement 4 and temperature sensor 12 is provided with bottom inwall 3, described digital temperature-controlled box comprises control module, control module is connected with heating arrangement 4 and temperature sensor 12, control module is also connected with power switch 7, intensification switch 8, cooling switch 9, temperature control display screen 10 and Shi Wen display screen 11, the outer wall of cup is provided with handle 5, handle 5 outside is coated with one deck plastics, described digital temperature-controlled box comprises housing, power switch 7, intensification switch 8, cooling switch 9, temperature control display screen 10 and Shi Wen display screen 11 are all arranged on housing.
When bitumen samples pours in the mould of every test respectively, the Elliptic Cylinder ready bitumen samples in an oven being poured fast into uncovered is filled with in mould device, turn on the power switch 7, by intensification switch 8, cooling switch 9, is adjusted to temperature and is preferably more than softening point temperature 90 DEG C, by handle 5, bitumen samples being flowed in the mould of test uniformly along filling with die orifice 1, completing filling mould easily and fast.
After having tested, by intensification switch 8 high-temperature heating, cause pitch when being in trickling state, topple over and fill with mould device medium pitch sample, inwall residual bitumen can be greatly reduced, alleviate the burden of cleaning and filling with mould device inwall residual bitumen.
