[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a mixing device for asphalt pavement construction, including a mobile platform 1, a mixing tank 2 fixedly mounted on the surface of the mobile platform 1, an asphalt pump 3 fixedly mounted on the surface of the mobile platform 1, the asphalt pump 3 being electrically connected to an external power source, and a connecting pipe 4 fixedly mounted between the asphalt pump 3 and the bottom of the mixing tank 2. The asphalt pump 3 is used to discharge the mixed material in the mixing tank 2 to the outside.
[0017] The mobile platform 1 includes a platform body 11. The four corners of the bottom of the platform body 11 are fixedly equipped with moving wheels 12. The moving wheels 12 drive the platform body 1 to move. The surface of the platform body 11 is symmetrically welded with handle frames 13 on the left and right sides. The handle frames 13 assist the platform body 11 in moving.
[0018] The inner cavity of the mixing tank 2 is equipped with a mixing mechanism 5 for mixing asphalt and other materials. The side wall of the mixing tank 2 is integrally formed with a heating chamber 6. The heating chamber 6 is equipped with a heating component 7 for heating the mixing tank 2. The heating component 7 heats the materials such as asphalt in the mixing tank 2 during mixing. An auxiliary heating mechanism 8 is also installed in the heating chamber 6. The auxiliary heating mechanism 8 can improve the heating effect of the mixing tank 2, make the heating of the mixing tank 2 more uniform, and improve the mixing quality of the materials such as asphalt in the mixing tank 2.
[0019] The top of the mixing tank 2 is integrally formed with a feed pipe 21, which is used to feed materials into the inner cavity of the mixing tank 2. The top of the mixing tank 2 is integrally formed with an exhaust pipe 22, which is used to discharge the fumes generated during the mixing process. The exhaust pipe 22 is equipped with a filter assembly 9, which filters the discharged fumes and reduces the pollution of the fumes to the surrounding environment.
[0020] like Figure 2 As shown, the stirring mechanism 5 includes a drive motor 51, which is fixedly mounted on the top of the mixing tank 2. The drive motor 51 is electrically connected to an external power source. The output end of the drive motor 51 is fixedly connected to a rotating shaft 52 that passes through the mixing tank 2. The drive motor 51 drives the rotating shaft 52 to rotate in the inner cavity of the mixing tank 2. Stirring plates 53 are evenly fixedly mounted on the side wall of the rotating shaft 52. The rotating shaft 52 drives the stirring plates 53 to rotate, thereby stirring the material located in the inner cavity of the mixing tank 2.
[0021] The heating assembly 7 includes a heater 71, which is fixedly installed inside the heating chamber 6. The heater 71 is a coil heater, which is distributed in a ring from top to bottom inside the heating chamber 6. The heater 71 is electrically connected to an external power source. The heater 71 heats the water in the heating chamber 6 by means of a water bath heating method, which improves the uniformity of heating of the mixing tank 2. The side wall of the heating chamber 6 is fixedly installed with an inlet pipe 72 and an outlet pipe 73 that are connected to the inner cavity. The inlet pipe 72 and the outlet pipe 73 are used to inject water into the heating chamber 6 and drain water, respectively. Switch valves 74 are fixedly installed in the inlet pipe 72 and the outlet pipe 73, respectively. The switch valves 74 are used to control the opening and closing of the inlet pipe 72 and the outlet pipe 73.
[0022] like Figure 2 and Figure 3 As shown, the auxiliary heating mechanism 8 includes an annular tube 81, which is fixedly assembled inside the heating chamber 6. One end of an air inlet pipe 82 is fixedly connected to the side wall of the annular tube 81, and the other end of the air inlet pipe 82 passes through the heating chamber 6 and is fixedly connected to an air pump 83. The air pump 83 is electrically connected to an external power source, and air is introduced into the annular tube 81 through the air pump 83 and the air inlet pipe 82. U-shaped tubes 84, which communicate with the inner cavity of the annular tube 81, are evenly fixedly connected to the bottom of the annular tube 81. Air outlet holes 85 are respectively opened on the opposite side walls of the U-shaped tubes 84. The U-shaped tubes 84 are located on both sides of the heater 71, and air is introduced into the heating chamber 6 through the U-shaped tubes 84. The air disturbs the water in the heating chamber 6, thereby improving the heating efficiency of the heater 71 on the water in the heating chamber 6, so that the water can be heated evenly in the heating chamber 6.
[0023] like Figure 4 As shown, the filter assembly 9 includes an upper filter frame 91 and a lower filter frame 92. A connecting shaft 93 is fixedly connected between the upper filter frame 91 and the lower filter frame 92. Filter layers 94 are embedded in the upper filter frame 91 and the lower filter frame 92 respectively. The filter layers 94 are made of activated carbon and fiber materials. By setting up dual filtration, the filtration effect on the gas emitted from the exhaust pipe 22 is enhanced.
[0024] Working principle: such as Figure 1As shown, this device is applied to the asphalt pavement construction process. First, the asphalt mixture is fed into the inner cavity of the mixing tank 2 through the feed pipe 21. The mixing mechanism 5 fully mixes the asphalt mixture in the inner cavity of the mixing tank 2. During the mixing process, water is introduced into the heating chamber 6 through the water inlet pipe 72 and heated by the heater 71. The mixing tank 2 is heated by water bath heating, which makes the asphalt mixture in the mixing tank 2 heat more evenly. At the same time, the U-shaped pipe 84 in the auxiliary heating component 8 introduces air into the heating chamber 6 through the air outlet 85. The introduced air further mixes the water in the heating chamber 6, improving the heating efficiency of the water. The gas generated during the heating and mixing of the asphalt mixture is discharged from the exhaust pipe 22. During the discharge process, the filter layer 94 filters the gas, thereby reducing the pollution to the surrounding environment.
