[0002] With the rapid development of technology and the increasing demands for environmental protection, emulsified asphalt is being used more and more in road resurfacing. The temperature of both the soap solution and asphalt in emulsified asphalt needs to be precisely controlled. Controlling the ratio of soap solution to asphalt is one of the key factors in ensuring the quality and performance of emulsified asphalt. Therefore, in order to determine the ratio of soap solution to asphalt in emulsified asphalt, small-scale tests need to be conducted using an asphalt testing device before actual production.

[0003] Chinese patent document CN210496774U discloses a laboratory asphalt colloid mill. This laboratory asphalt colloid mill can precisely control the amount of asphalt used during feeding, ensuring the accuracy of the mixing ratio and the reliability of the test data. However, a large amount of asphalt fumes are generated during the heating of asphalt and the discharge of emulsified asphalt. Frequent inhalation of harmful asphalt fumes by laboratory personnel can cause significant harm to their health.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0042] Please see Figures 1 to 3 This utility model provides an asphalt testing device, including a colloid mill 1, a feed hopper 2, a discharge pipe 3, a flue gas extraction hood 4, a first exhaust pipe 5, a smoke blocking box 6, a second exhaust pipe 7, and an exhaust fan.

[0043] The colloid mill 1 has shearing, stirring, and mixing functions, enabling the asphalt and soap solution to be uniformly mixed to form stable emulsified asphalt. Therefore, after the experiment, the ratio of soap solution to asphalt during emulsified asphalt production can be determined by testing the performance of the emulsified asphalt. The fume extraction hood 4 is fixedly mounted above the feed hopper 2 and connected to the first exhaust pipe 5, which in turn is connected to an exhaust fan. Therefore, by mounting the fume extraction hood 4 above the feed hopper 2, the asphalt fumes escaping from the feed hopper 2 can be drawn into the first exhaust pipe 5, allowing the asphalt fumes to be discharged outside the laboratory through the first exhaust pipe 5 and the exhaust fan. This improves the laboratory environment and reduces the harm of asphalt fumes to laboratory personnel.

[0044] The smoke-blocking box 6 is located below the feed hopper 2, and the top of the smoke-blocking box 6 has an opening for the discharge pipe 3 to extend into the smoke-blocking box 6. The second exhaust pipe 7 is connected to the smoke-blocking box 6 and is also connected to the exhaust fan. Since the discharge pipe 3 releases a large amount of asphalt fumes when discharging emulsified asphalt, by setting up a smoke-blocking box 6 below the feed hopper 2 to accommodate the discharge pipe 3 and connecting the second exhaust pipe 7 to the smoke-blocking box 6, the asphalt fumes generated when the discharge pipe 3 discharges material can be prevented from entering the laboratory, and the asphalt fumes in the smoke-blocking box 6 can be discharged outside the laboratory by the exhaust fan, thereby further reducing the concentration of asphalt fumes in the laboratory and improving the health of the laboratory personnel.

[0045] Specifically, the exhaust fan can be part of an existing asphalt fume treatment system (e.g., CN218763437U), thereby enabling the asphalt fumes in the laboratory to be treated by the fume treatment system to meet the standards before being discharged, thus avoiding pollution of the environment by the asphalt fumes.

[0046] Specifically, the second exhaust pipe 7 can be connected to the first exhaust pipe 5, so that the asphalt fumes in the smoke-blocking box 6 can flow into the first exhaust pipe 5 and be discharged out of the laboratory together with the asphalt fumes drawn in by the smoke extraction hood 4 through the first exhaust pipe 5. Therefore, the length of the exhaust pipe can be reduced.

[0047] Optionally, the smoke-blocking box 6 includes a box body 61 and a smoke-blocking door 62 vertically inserted into the front opening of the box body 61. Laboratory personnel can open and close the smoke-blocking box 6 by moving the smoke-blocking door 62 up and down, ensuring that the receiving bucket 14 used to collect emulsified asphalt can be put into and taken out of the smoke-blocking box 6.

[0048] In order to facilitate the insertion of the smoke baffle 62 into the front of the housing 61, an insertion port for the smoke baffle 62 is provided on the top of the housing 61, so that the smoke baffle 62 can be inserted vertically.

[0049] Optionally, the top of the housing 61 is provided with an observation window. The discharge status of the discharge pipe 3 inside the housing 61 can be observed through the observation window. Preferably, when the experimenter observes through the observation window that the discharge port of the discharge pipe 3 is no longer discharging emulsified asphalt, the receiving bucket 14 can be removed from the housing 61, preventing the emulsified asphalt from dripping onto the ground and helping to maintain a clean laboratory environment.

[0050] Optionally, the upper part of the smoke baffle 62 is provided with a carrying handle 621. The carrying handle 621 can be an opening structure that extends through the upper part of the smoke baffle 62, or it can be a groove structure located on the front side of the upper part of the smoke baffle 62, thereby facilitating the experimenter to pick up and put down the smoke baffle 62.

[0051] Optionally, the discharge pipe 3 includes a first discharge pipe 31 and a second discharge pipe 32; the first discharge pipe 31 is fixedly connected to the discharge end of the colloid mill 1; the second discharge pipe 32 is detachably connected to the first discharge pipe 31 via a flange, and the discharge end of the second discharge pipe 32 extends into the smoke-blocking box 6 through the opening. This invention designs the discharge pipe 3 as having two detachable parts, so that when a part of the discharge pipe 3 (e.g., the first discharge pipe 31 or the second discharge pipe 32) is damaged or blocked, it is not necessary to completely remove the discharge pipe 3, thus facilitating maintenance and cleaning.

[0052] Furthermore, designing the discharge pipe 3 as two detachable parts facilitates placing the discharge port of the discharge pipe 3 inside the smoke-blocking box 6. Before installing the smoke-blocking box 6 below the feed hopper 2, the second discharge pipe 32 can be installed on the smoke-blocking box 6 first, and then the first discharge pipe 31 and the second discharge pipe 32 can be assembled, thereby ensuring that the discharge port of the discharge pipe 3 is located inside the smoke-blocking box 6.

[0053] Optionally, a limiting ring 13 and a sealing ring 8 are fitted onto the second discharge pipe 32; the limiting ring 13 is fixedly fitted onto the second discharge pipe 32 and is located above the sealing ring 8; when the second discharge pipe 32 is assembled onto the smoke-blocking box 6, the limiting ring 13 presses the sealing ring 8 downward, so that the sealing ring can contact the top of the smoke-blocking box 6, thereby sealing the opening at the top of the smoke-blocking box 6 and preventing asphalt fumes from leaking out from the opening at the top of the smoke-blocking box 6.

[0054] Optionally, the colloid mill 1 includes a motor 101, a housing 102, a main shaft 103 connected to the output shaft of the motor 101 and disposed within the housing 102, a grinding chamber 104 connected to the housing 102, a rotor disc (not shown in the figure) sleeved on the main shaft 103 and located within the grinding chamber 104, and a stator disc (not shown in the figure) fixedly disposed within the grinding chamber 104 and cooperating with the rotor disc. The feed hopper 2 and the discharge pipe 3 are both connected to the grinding chamber 104. When the motor 101 is working, it drives the main shaft 103 and the rotor disc to rotate at high speed, while the stator disc remains stationary. Therefore, when the mixture of soap solution and asphalt is fed into the grinding chamber 104, and the mixture is located in the gap between the stator disc and the high-speed rotating rotor disc, the mixture is subjected to strong shearing and frictional forces, thereby effectively emulsifying, dispersing, homogenizing, and pulverizing it to form stable emulsified asphalt.

[0055] Optionally, the asphalt testing apparatus further includes a support frame 9, a driving pulley 10, a driven pulley 11, and a transmission belt 12.

[0056] The support frame 9 is used to support the machine box 102, so that the colloid mill 1 can be set at a high position, which is convenient for collecting emulsified asphalt, and also allows the discharge port of the discharge pipe 3 to extend into the smoke-blocking box 6.

[0057] The driving pulley 10 is coaxially arranged with the output shaft of the motor 101, and the driven pulley 11 is coaxially arranged with the main shaft 103. The transmission belt 12 is wound around both the driving pulley 10 and the driven pulley 11. The driving pulley 10, the driven pulley 11, and the transmission belt 12 wound around both the driving pulley 10 and the driven pulley 11 constitute a belt drive mechanism. This ensures that the colloid mill 1 can work when it is installed at a high position, and also reduces the load on the support frame 9, thus preventing safety hazards in the laboratory.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
