[0002] Emulsified asphalt is a liquid asphalt that is formed by the reaction of asphalt and emulsifiers under certain process conditions, which is oil-in-water or water-in-oil (which one is in the other depends on the type of emulsifier). Emulsified asphalt is a road construction material that is usually used at high temperatures, and is diffused into water and liquefied to have very low viscosity and good fluidity at room temperature after mechanical stirring and chemical stabilization (emulsification). It can be used at room temperature or with cold and wet stones. During the storage process, emulsified asphalt often has asphalt particle flocculation and agglomeration.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The heat insulation mechanism 3 includes an annular groove 301, a spring 302, a temperature sensor 303, a heat insulation cover 304, a slot 305, a block 306 and a lever 307. An annular groove 301 is provided on one side of the surface of the base 2, a spring 302 is provided inside the base 2, a temperature sensor 303 is installed on one side of the surface of the base 2, the annular groove 301 is engaged with the heat insulation cover 304, a slot 305 is provided on one side of the surface of the heat insulation cover 304, one end of the spring 302 is fixedly connected with the block 306, and one side of the surface of the block 306 is fixedly connected with the lever 307. Through the arrangement of the annular groove 301, the spring 302, the temperature sensor 303, the heat insulation cover 304, the slot 305, the block 306 and the lever 307, when in use, first align the heat insulation cover 304 with the annular groove 301, and then press the insulation cover 304 to release the temperature sensor 303. When the block 306 moves to the position of the card slot 305, the spring 302 begins to reset without being subject to external force, so that the spring 302 drives the block 306 to engage with the card slot 305. At this time, the heat shield is engaged with the annular groove 301 of 304, so as to avoid the influence of the external temperature change on the accuracy of the test. At the same time, the temperature sensor 303 can monitor the temperature change inside the heat shield 304 in real time, so as to further improve the test accuracy. When the heat shield 304 needs to be removed, the lever 307 is firstly pushed, so that the lever 307 drives the block 306 to disengage from the card slot 305. At this time, the heat shield 304 can be pulled to make the heat shield 304 separate from the base 2, so as to achieve the purpose of convenient disassembly and assembly.

[0021] Furthermore, the other end of the spring 302 is fixedly connected to the base 2, and the block 306 is engaged with the slot 305. Through the setting of the spring 302, when in use, the spring 302 will shrink and deform when squeezed. When the squeezing force disappears, the spring 302 will reset due to its own characteristics, so that the spring 302 can provide power for the reset movement of the block 306.

[0022] Furthermore, the heat insulation cover 304 is made of heat insulation material, and the card slots 305 are provided with four groups. Through the setting of the heat insulation cover 304, when in use, the heat insulation cover 304 can reduce the heat exchange between the inside of the heat insulation cover 304 and the outside during the test, thereby avoiding the outside temperature change from affecting the test results.

[0023] Furthermore, the clamping mechanism 4 includes a support frame 401, a limiting groove 402, a rotating key 403, a screw rod 404, a first slider 405, a second slider 406, a first clamping plate 407, a second clamping plate 408 and a limiting rod 409. The support frame 401 is connected to one side of the surface of the base 2, and the limiting groove 402 is provided on one side of the surface of the base 2. The rotating key 403 is installed on one side of the surface of the support frame 401, and the screw rod 404 is connected to one side of the surface of the rotating key 403. The first slider 405 is threadedly connected to one side of the surface of the screw rod 404, and the second slider 406 is threadedly connected to one side of the surface of the screw rod 404. The first clamping plate 407 is fixedly connected to one side of the surface of the first slider 405, and the second clamping plate 408 is fixedly connected to one side of the surface of the second slider 406. The limiting rod 409 runs through the interior of the first clamping plate 407, and the support frame 401 is connected to one side of the surface of the base 2. , the setting of the limiting groove 402, the rotating key 403, the screw rod 404, the first slider 405, the second slider 406, the first clamping plate 407, the second clamping plate 408 and the limiting rod 409. When in use, first insert the test tube 1 into the limiting groove 402, and then rotate the rotating key 403, so that the rotating key 403 drives the screw rod 404 to rotate. Since the thread directions at both ends of the screw rod 404 are opposite, and the first slider 405 and the second slider 406 are respectively arranged at both ends of the screw rod 404, the screw rod 404 drives the first slider 405 and the second slider 406 to move relative to each other along the direction of the screw rod 404, so that the first slider 405 and the second slider 406 drive the first clamping plate 407 and the second clamping plate 408 to move relative to each other, so that the first clamping plate 407 and the second clamping plate 408 clamp the test tube 1, thereby preventing the test tube 1 from tipping over during the test.

[0024] Furthermore, the support frame 401 is provided with four groups, the thread directions of the two ends of the screw rod 404 are opposite, and the limiting rod 409 passes through the second clamping plate 408. Through the setting of the support frame 401, when in use, the four groups of support frames 401 can provide support for the screw rod 404 and the limiting rod 409, and the support frame 401 can limit the position of the screw rod 404 and the limiting rod 409.

[0025] Furthermore, the first clamp 407 is in contact with the test tube 1, and the second clamp 408 is in contact with the test tube 1. By setting the first clamp 407 and the second clamp 408, when in use, the first clamp 407 and the second clamp 408 cooperate with each other to clamp and fix the test tube 1, thereby improving the stability of the test tube 1 during the test.

[0026] Working principle: first, insert the test tube 1 into the limit groove 402, and then rotate the rotation key 403, so that the rotation key 403 drives the screw rod 404 to rotate. Since the threads at both ends of the screw rod 404 are in opposite directions, and the first slider 405 and the second slider 406 are respectively arranged at both ends of the screw rod 404, the screw rod 404 drives the first slider 405 and the second slider 406 to move relative to each other along the direction of the screw rod 404, so that the first slider 405 and the second slider 406 drive the first clamping plate 407 and the second clamping plate 408 to move relative to each other, so that the first clamping plate 407 and the second clamping plate 408 clamp the test tube 1, so as to prevent the test tube 1 from tipping over during the test, and then align the heat insulation cover 304 with the annular groove 301, and then press the heat insulation cover 304, so that the heat insulation cover 304 squeezes the block 306 to move, so that the block 306 squeezes the spring 302 to contract. When the block 306 moves to the slot 305 position, the spring 302 begins to reset without being subject to external force, so that the spring 302 drives the block 306 to engage with the slot 305. At this time, the heat shield is engaged with the annular groove 301 of 304, so as to avoid the influence of external temperature changes on the accuracy of the test. At the same time, the temperature sensor 303 can monitor the temperature changes inside the heat shield 304 in real time, so as to further improve the test accuracy. When the heat shield 304 needs to be removed, the lever 307 is first pushed, so that the lever 307 drives the block 306 to disengage from the slot 305. At this time, the heat shield 304 can be pulled to separate the heat shield 304 from the base 2, so as to achieve the purpose of convenient disassembly and assembly.
