Description

Technical Field

[0001] The utility model relates to an asphalt aging test box, belonging to the technical field of asphalt aging test boxes. Background Art

[0002] Asphalt is an organic cementitious material that provides waterproofing, moisture resistance, and corrosion resistance. Asphalt can be primarily categorized into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue from crude oil distillation. Natural asphalt is stored underground, sometimes forming deposits or accumulating on the Earth's surface. Asphalt is primarily used in industries such as coatings, plastics, and rubber, as well as in road paving. UV aging testing of asphalt requires the use of an aging test oven.

[0003] In the existing aging test oven, the positions of the ultraviolet lamp and the sample tray are often fixed during use, and only one sample can be placed in the test oven. Therefore, when taking the sample out of the test oven after the aging test, there is a risk of burns due to the high temperature in the oven, and the operation is cumbersome. In addition, when re-taking and re-loading the material, the equipment needs to wait, which wastes time. In view of the above shortcomings, the utility model proposes an asphalt aging test chamber.

[0006] A further improvement is that an observation window is provided at the left end of the front side of the test box, a box door is hinged in the middle of the front side of the test box, a sleeve is provided in the middle of the lower end of the test box cavity, and an inlay is opened through the middle of the sleeve, and an exhaust fan is provided on the rear side of the test box.

[0007] A further improvement is that the sample stage rotation mechanism includes a rotating shaft, and a sample turntable is provided on the top surface of the rotating shaft, a bearing is embedded on the rotating shaft body, and a driven gear is provided at the lower end of the rotating shaft, and a motor and a driving gear are engaged on one side of the driven gear.

[0008] As a further improvement, the sample turntable comprises a sample turntable body, and a top surface of the sample turntable body is provided with a plurality of sample placement grooves in an annular array, and a sealing gasket is sleeved on the periphery of each of the sample placement grooves.

[0009] A further improvement is that the aging test assembly includes a telescope and a test cover arranged at the lower end of the telescope, and an ultraviolet lamp is provided on the top surface of the test cover cavity. An air inlet nozzle and a temperature sensor are provided on the cover body of the test cover, and the outer end of the air inlet nozzle is connected to the hot air generator through an air inlet hose.

[0023] The aging test assembly 3 includes a telescope 31 and a test cover 32 arranged at the lower end of the telescope 31. An ultraviolet lamp 33 is provided on the top surface of the test cover 32 cavity. An air inlet nozzle 34 and a temperature sensor 35 are provided on the cover body of the test cover 32.

[0025] Working principle:

[0026] First, an asphalt sample is placed in each sample placement slot 222 on the sample turntable body 221, and then the telescopic device 31 on the aging test assembly 3 descends to drive the test cover 32 to abut against a corresponding sealing gasket 223 for sealing, and then the ultraviolet lamp tube 33 is turned on to perform an aging test on the asphalt sample in the test cover 32, and the hot air generator 5 blows hot air into the test cover 32 through the air inlet nozzle 34 to cooperate with the aging test. When the temperature in the test cover 32 reaches the value specified by the temperature sensor 35, the hot air generator 5 pauses, and then stops for the set time to age.

[0027] In addition, when the aging test is completed, the telescopic device 31 rises and drives the test cover 32 to open. At this time, a stream of hot air will be generated in the test cover 32 and drawn out backwards through the exhaust fan 15. Then the motor 25 rotates to make the sample turntable body 221 rotate counterclockwise by the distance between the sample placement slots 222. Then the aging test component 3 re-seales the next asphalt sample for the sealing cover and heating aging test. At this time, the asphalt sample that has undergone the aging test will rotate to the corresponding position of the box door 12, and the box door 12 can only be opened to take samples for analysis.
