[0037] The application will be further described in detail below with reference to the accompanying drawings. Figure 1 - The application is described in detail below with reference to the accompanying drawings. Figure 4 , and further described in detail.

[0038] The application discloses a kind of net taste asphalt preparation and smoke test integrated test device.

[0039] A kind of net taste asphalt preparation and smoke test integrated test device, the device is used to the preparation of asphalt and the detection of smoke.

[0040] Reference Figure 1 And Figure 2 As shown in the drawings, the test device includes asphalt test barrel 1, test barrel cover 2, stirring mechanism 3 and smoke detector 5; test barrel cover 2 is detachably connected with asphalt test barrel 1, and asphalt test barrel 1 can be made of a metal barrel or a barrel made of a high-temperature-resistant material according to requirements. Since it is used for testing, the size of the asphalt test barrel 1 should not be too large, and a cylindrical barrel with a height of about 200 mm and a diameter of about 165 mm can be selected. Similarly, the inner diameter of the test barrel cover 2 is also the same as the outer diameter of the asphalt test barrel 1, so that the test barrel cover 2 can be stably covered on the asphalt test barrel 1.

[0041] The detachable connection of the asphalt test barrel 1 and the test barrel cover 2 can be screwing. An external thread is formed on the top outer wall of the asphalt test barrel 1, and an internal thread is formed on the inner wall of the test barrel cover 2. The asphalt test barrel 1 and the test barrel cover 2 are connected by screwing the external thread and the internal thread. When disassembly is needed, the two can be separated by rotating in the opposite direction. The detachable test barrel cover 2 can be easily cleaned and reused. One set of test barrel cover 2 can be used with the same size asphalt test barrel 1, saving test cost.

[0042] The test barrel cover 2 is provided with a stirring connection pipe 21, an air inlet pipe 22 and an air outlet pipe 23. The stirring connection pipe 21 is located at the center of the test barrel cover 2, and the air inlet pipe 22 and the air outlet pipe 23 are respectively located on both sides of the stirring connection pipe 21. The stirring connection pipe 21 is connected with the stirring mechanism 3. The stirring connection pipe 21 located at the center can centrally stir the asphalt raw materials during stirring, so that a stirring vortex can be formed in the asphalt test barrel 1, ensuring that the asphalt raw materials at each position in the asphalt test barrel 1 can be uniformly and fully stirred.

[0043] Among them, the stirring mechanism 3 can adopt an electric mixer and a stirring frame. The stirring end of the electric mixer is connected with the stirring frame and can extend into the asphalt test barrel 1. After starting the electric mixer, the stirring frame is driven to rotate, so that the stirring frame located in the asphalt test barrel 1 can stir the asphalt raw materials.

[0044] Both the inlet pipe 22 and the outlet pipe 23 are equipped with a flue gas detector 5 or a rubber plug 4. When the flue gas detector 5 is needed, the rubber plug 4 can be removed from the inlet pipe 22 and the outlet pipe 23 and then inserted into the flue gas detector 5. Conversely, when the flue gas detector 5 is not needed, the rubber plug 4 can be used to block the inlet pipe 22 and the outlet pipe 23.

[0045] The flue gas detector 5 includes an inflation end and a detection end. The inflation end is connected to the air inlet pipe 22, and the detection end is connected to the air outlet pipe 23. The inflation end can deliver gas to the asphalt test barrel 1 through the air inlet pipe 22, and the gas is discharged from the air outlet pipe 23 and detected by the detection end.

[0046] Specifically, after the test barrel lid 2 is opened, the asphalt test barrel 1 is placed into the asphalt test barrel 1, and then the test barrel lid 2 is closed. The asphalt raw material is stirred and shaped using the stirring mechanism 3. During the stirring process, the air inlet pipe 22 and the air outlet pipe 23 are blocked with rubber stoppers 4 to prevent heat loss. After stirring is completed, the rubber stoppers 4 are removed and the flue gas detectors 5 are inserted into the air inlet pipe 22 and the air outlet pipe 23 respectively. The air inlet pipe 22 delivers gas into the asphalt test barrel 1, and at the same time, the gas in the asphalt test barrel 1 is discharged from the air outlet pipe 23. The flow of gas is used to enable the flue gas detectors 5 to detect whether the asphalt is odorless.

[0047] By integrating the two experimental processes of odorless asphalt preparation and asphalt fume testing, the experimental procedures are streamlined, and the secondary repeated heating of asphalt is reduced, which greatly shortens the entire experimental cycle and improves the experimental efficiency of asphalt preparation and asphalt fume testing.

[0048] Furthermore, during use, it includes a odorless asphalt preparation stage and an asphalt fume testing stage. The odorless asphalt preparation stage is used to stir the asphalt raw materials into odorless asphalt. Specifically, the high-temperature asphalt raw materials are placed into the asphalt test barrel 1, and the odorless asphalt is formed by stirring through the stirring mechanism 3.

[0049] In the asphalt fume testing stage, the formed odorless asphalt is subjected to fume testing to determine whether the odor level of the formed asphalt meets the standard. Specifically, the rubber stopper 4 is removed and replaced with a fume detector 5. Gas is then introduced through the inlet pipe 22 and discharged through the outlet pipe 23, allowing the gas to flow from the detection end of the fume detector 5. The fume detector 5 is used to detect whether the odorless asphalt meets the odorless standard.

[0050] Furthermore, refer to Figure 1 As shown, during the preparation stage of the odorless asphalt, the air inlet pipe 22 and the air outlet pipe 23 are connected to the rubber stopper 4. During the preparation stage of the odorless asphalt, the air inlet pipe 22 and the air outlet pipe 23 are closed by the rubber stopper 4 to reduce the temperature leakage inside the asphalt test barrel 1, so that the asphalt raw material is in a plastic and fluid softened state during the mixing process.

[0051] Further, referring to Figure 2 As shown, during the asphalt fume detection stage, the gas inlet pipe 22 is connected with the gas outlet pipe 23 with the fume detector 5. When the gas inlet pipe 22 is connected with the gas outlet pipe 23, the gas inlet pipe 22 delivers gas into the asphalt test barrel 1. The gas enters the asphalt test barrel 1, so that a positive pressure is formed in the asphalt test barrel 1. The gas in the asphalt test barrel 1 is discharged from the gas outlet pipe 23. During the discharging process, the gas passes through the fume detector 5. The fume detector 5 detects the components in the gas to ensure that the odor of the asphalt is qualified.

[0052] Further, referring to Figure 1 Or Figure 2 As shown, the gas inlet pipe 22 and the gas outlet pipe 23 are both inclined at a preset angle. The gas inlet pipe 22 and the gas outlet pipe 23 are spaced apart at a preset angle. This can prevent the use area of the stirring mechanism 3 from being too large and avoid the stirring mechanism 3 being affected by interference. In particular, when the fume detector 5 is replaced with the rubber plug 4, a wider replacement space is provided, so that the installation is more convenient.

[0053] In some embodiments, the inner wall of the test barrel cover 2 is provided with a sealing layer. The sealing layer can be a high-temperature-resistant plastic layer, a high-temperature-resistant plastic layer, or a graphite sealing gasket. The sealing layer is used to provide a sealing effect to prevent gas leakage when the test barrel cover 2 is connected with the asphalt test barrel 1 and to ensure the stability of the heat of the asphalt test barrel 1. The sealing layer has a layered structure, which is difficult to show in the figure, so the sealing layer is not shown in the figure.

[0054] Further, referring to Figure 2 As shown, the detection end of the fume detector 5 is provided with a rubber ring 51. The detection end of the fume detector 5 is inserted into the gas inlet pipe 22 or the gas outlet pipe 23. Therefore, the rubber ring 51 can block the gap of the gas inlet pipe 22 or the gas outlet pipe 23 to prevent gas from being discharged from the gap and to affect the detection accuracy of the fume detector 5.

[0055] Further, referring to Figure 3 As shown, the stirring connection pipe 21 is provided with a sealing member 6. The sealing member 6 is connected with the pipe opening of the stirring connection pipe 21. The stirring end of the stirring mechanism 3 is pivotally connected with the sealing member 6. The sealing member 6 can be a sealing bearing. The sealing bearing is installed at the pipe opening of the stirring connection pipe 21. When the stirring mechanism 3 is an electric mixer and a stirring frame, the stirring end of the stirring mechanism 3 is the stirring frame. The stirring frame is pivotally connected with the sealing bearing. The stirring frame can rotate along the sealing bearing. In addition to the pivot point, the sealing bearing is closed to the pipe opening of the stirring connection pipe 21 by a sealing material. Therefore, the sealing performance can be further improved, and the heat loss can be prevented.

[0056] Wherein, when the stirring frame is pivotally connected with the sealing bearing, the electric mixer and the stirring frame can be detachably connected, so as to separate the electric mixer and the stirring frame for maintenance or replacement. The driving end of the electric mixer can be connected with the stirring frame by using high-temperature-resistant and heat-insulating materials, such as graphite materials, to avoid high temperature from being transferred to the driving end of the electric mixer and affecting the service life.

[0057] In some embodiments, reference is made to Figure 4 As shown, the sealing member 6 is further provided with a heating member 7. The heating member 7 can be a heating ring, and the heating ring is provided with an electric heating wire. The heating ring is connected with a power line to provide power supply for heating. After the heating ring is heated, the heating wire in the heating ring generates heat, which can be transferred to the stirring end of the stirring mechanism 3, i.e. the stirring frame. The stirring frame can be made of metal material. Therefore, when the heat of the heating ring is transferred to the stirring frame, the heat can be transferred to the asphalt test barrel 1 through the stirring frame. The heat is transferred through the stirring frame, thereby reducing the heat loss of the asphalt raw materials in the asphalt mixing barrel during the stirring process, and maintaining the plastic and flow softening state of the asphalt raw materials.

[0058] Wherein, the surface of the heating ring is provided with a heat shield 71, and the heat shield 71 is provided with a through hole for the stirring end of the stirring mechanism 3 to penetrate. After the stirring frame penetrates the through hole, the heating ring and the sealing member 6, the stirring frame extends into the asphalt test barrel 1. The heat shield 71 can prevent the heat of the heating ring from leaking out, and also prevent workers from being scalded by touching the heating ring.

[0059] Further, the surface of the heat shield 71 can be provided with a temperature sensor 72 and a display screen 73. The display screen 73 can display the temperature data detected by the temperature sensor 72, thereby reminding the workers to be careful of the high temperature on the heat shield 71 and avoiding the workers from touching it casually.

[0060] Wherein, the bottom of the display screen 73 is provided with a heat insulation pad to separate the display screen 73 from the heat shield 71, thereby avoiding the heat from affecting the display screen 73.

[0061] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same parts are indicated by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
