[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0021] The present application provides a preparation device for rock asphalt modified asphalt, which is mainly used to solve the problem that the melted asphalt will adhere to the stirring blades during the stirring process, and needs to be manually cleaned regularly, which reduces the sustainability of the drying cylinder, and provides the following technical solutions. Figure 1-Figure 3 Make a detailed description:
[0022] A preparation device for rock asphalt modified asphalt, comprising:
[0023] A fan 2 is installed on one side of the fan 1, a discharge hopper 3 is connected to the middle of the bottom of the fan 1, and brackets are arranged on both sides of the bottom;
[0024] The heating kettle 4 is arranged on the top of the side of the wind hood 1 away from the fan 2. A guide hopper 401 is connected obliquely downward between the middle of the side wall of the heating kettle 4 and the wind hood 1. The lower end of the guide hopper 401 is located above one side of the discharge hopper 3. Support legs are arranged between the bottom surface of the heating kettle 4 and the wind hood 1. A burner 5 is installed on the top of the wind hood 1 below the heating kettle 4.
[0025] A transmission barrel 6 is arranged on the other side of the top of the wind hood 1. The end of the transmission barrel 6 close to the discharge hopper 3 is conical and is connected to the wind hood 1 by a material guide pipe 7. The connection between the material guide pipe 7 and the wind hood 1 is located above the other side of the discharge hopper 3. A motor 8 is installed at the end of the transmission barrel 6 away from the discharge hopper 3. The output shaft of the motor 8 passes through the wall of the transmission barrel 6 and is connected to a rotating rod 9. An auger blade 10 is installed on the surface of the rotating rod 9. A feed pipe 11 is connected to the side of the top of the transmission barrel 6 close to the motor 8, and the upper end of the feed pipe 11 is connected to a feed barrel 12.
[0026] More specifically, the specific implementation process and principle of the preparation device of rock asphalt modified asphalt are as follows:
[0027] When in use, the block asphalt is put into the heating kettle 4 so that its stacking height exceeds the upper port of the guide hopper 401, and is heated to a melted state through the burner 5, and is introduced into the wind hood 1 through the guide hopper 401. At the same time, the staff adds the modifier powder into the transmission barrel 6 through the feed barrel 12, and the motor 8 drives the auger blade 10 to rotate, and the modifier powder is sent into the wind hood 1 through the guide pipe 7. In the wind hood 1, the airflow generated by the fan 2 promotes the modifier powder to fully contact and mix with the falling rock asphalt liquid. This design uses airflow instead of traditional physical stirring blades to achieve the purpose of mixing, effectively avoiding the problem of regular manual cleaning due to the modified asphalt adhering to the stirring blades, and improving the mixing efficiency.
[0028] like Figure 3As shown, in some embodiments, the side of the hood 1 away from the fan 2 is connected to the exhaust pipe 13. More specifically, the side of the hood 1 away from the fan 2 is connected to the exhaust pipe 13. This is to ensure that the exhaust gas generated in the mixing process can be discharged in time to ensure that the production environment is well ventilated. Through the setting of the exhaust pipe 13, the generated exhaust gas can be effectively discharged from the device to avoid adverse effects on the production environment and operators.
[0029] like Figure 3 As shown, in some embodiments, the discharge hopper 3 is triangular in shape. More specifically, the triangular design helps to guide the material to flow in a specific direction, reduce the retention of material in the hopper, improve the efficiency of unloading, and allow the material to be discharged from the discharge hopper 3 more smoothly.
[0030] like Figure 3 As shown, in some embodiments, a dust-proof net 14 is provided inside the air hood 1 below the guide hopper 401. More specifically, the dust-proof net 14 provided inside the air hood 1 is used to prevent the modifier powder from escaping from the exhaust pipe 13 to the outside and diffusing into the working environment during the production process, thereby ensuring the safety and cleanliness of the production environment.
[0031] like Figure 3 As shown, in some embodiments, the inner wall of the wind shield 1 is located below the material guide pipe 7 and is provided with material-push wheels 15 at equal intervals. More specifically, the material-push wheels 15 have the following functions:
[0032] First, slowing down the falling speed: the paddle wheel 15 generates resistance to the falling modifier powder through its rotation, thereby slowing down the falling speed of the powder, which helps to increase the residence time of the powder in the wind hood 1, providing more sufficient time for the mixing of the powder and the melted asphalt;
[0033] Second, powder dispersion: the rotation of the paddle wheel 15 can disperse the aggregated powder and make it more evenly distributed in the asphalt. This dispersion effect helps to improve the homogeneity of the mixture, thereby improving the quality of the final product;
[0034] Third, promoting mixing: the equally spaced paddle wheels 15 can evenly distribute the modifier powder over the entire cross section of the wind hood 1, so that the powder can be more fully contacted and mixed with the asphalt during the falling process, thereby improving the uniformity and quality of the mixture.
[0035] like Figure 3 As shown, in some embodiments, a discharge valve is installed on the pipe body of the material guide pipe 7. More specifically, by adjusting the opening of the discharge valve, the speed and amount of material flowing out of the discharge pipe can be accurately controlled, which is crucial to ensuring the ratio accuracy in the modified asphalt preparation process.
[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
