Description

Technical Field

[0001] This utility model relates to the technical field of asphalt production and processing equipment, and in particular to a heating device for the production and processing of polymer-modified foamed asphalt. Background Technology

[0002] Polymer-modified foamed asphalt is produced by modifying high-molecular-weight polymers (such as SBS and PE) into high-temperature asphalt, thereby improving its performance. When water droplets are added to the modified asphalt at high temperatures, vapor bubbles form, creating a chain reaction that significantly enhances its bonding properties. This material exhibits strong cohesion and good stability, making it suitable for long-term storage and cold compaction. Polymer-modified foamed asphalt is widely used in the construction and maintenance of various road surfaces, such as highways, urban expressways, airport runways, and parking lots. By mixing it with other road materials, it can better meet the needs of different road sections and working conditions.

[0003] However, existing heating devices for the production and processing of polymer-modified foamed asphalt cannot adequately stir the asphalt during the heating process, causing the asphalt to easily settle at the bottom of the tank, which affects the stirring and processing efficiency of the asphalt. Utility Model Content

[0004] The main purpose of this invention is to provide a heating device for the production and processing of polymer-modified foamed asphalt, which can effectively solve the problem of insufficient asphalt mixing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A heating device for the production and processing of polymer-modified foamed asphalt includes an outer tank. Supporting mechanisms are symmetrically fixedly connected to the left and right ends of the outer surface of the outer tank. A motor is fixedly installed in the middle of the right end of the outer surface of the outer tank. A feeding pipe is fixedly connected to the upper left side of the outer surface of the outer tank. Several discharging components are fixedly connected at intervals to the lower part of the outer surface of the outer tank. An inner tank is fixedly connected to the middle of the inner cavity of the outer tank. A heating mechanism is fixedly installed in the gap between the outer surface of the inner tank and the inner surface of the outer tank. A rotating shaft is rotatably connected to the middle of the inner cavity of the outer tank. The right end of the outer surface of the rotating shaft is fixedly connected to the left output end of the motor. Several stirring mechanisms are fixedly connected at intervals to the outer surface of the rotating shaft. Each stirring mechanism is fixedly connected to a connecting component. Several scraping mechanisms are fixedly connected in a circular array on the side of each pair of connecting components that are close to each other.

[0007] Preferably, the support mechanism includes a support frame, an arc-shaped base is fixedly connected to the upper part of the outer surface of the support frame, an annular sleeve is fixedly connected to the upper part of the outer surface of the arc-shaped base, and the inner surface of the annular sleeve is fixedly connected to an outer surface of the outer tank.

[0008] Preferably, the discharge assembly includes a discharge pipe, and a leak-proof plug is slidably connected to the lower part of the inner cavity of the discharge pipe.

[0009] Preferably, the stirring mechanism includes a fixed sleeve, on which a plurality of stirring plates are fixedly connected in a ring array on the outer surface of the fixed sleeve, and the inner surface of the fixed sleeve is fixedly connected to the outer surface of the rotating shaft.

[0010] Preferably, the connecting assembly includes several connecting plates, and each pair of connecting plates has an arc-shaped plate fixedly connected to one side of each other on its outer surface, and the connecting plates are respectively fixedly connected to the corresponding stirring plates.

[0011] Preferably, the scraping mechanism includes a transmission plate, and a scraper is fixedly connected to the middle of the side of the outer surface of the transmission plate away from the rotation axis. The left and right sides of the outer surface of the transmission plate are respectively fixedly connected to the outer surfaces of two adjacent arc-shaped plates.

[0012] Preferably, the heating mechanism includes a heating tube, and a plurality of mounting kits are spaced apart on the outer surface of the heating tube, and the outer surfaces of the plurality of mounting kits are fixedly connected to an inner surface of the outer tank and an outer surface of the inner tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention provides stable support for the outer tank via a support mechanism, facilitates the discharge of asphalt via a discharge assembly, and heats the asphalt within the inner tank via a heating mechanism, thus improving the device's practicality. A stirring mechanism facilitates the mixing of the asphalt, and a connecting assembly allows for the connection of several scraping mechanisms. These scraping mechanisms not only thoroughly mix the asphalt but also scrape off residue adhering to the inner tank wall, enhancing the device's practicality and versatility.

[0015] This invention connects several arc-shaped plates to corresponding mixing plates, so that when the mixing plates rotate, they can drive the adjacent transmission plates to rotate synchronously. At the same time, the mixing plates and scraper plates begin to fully mix the asphalt in the inner cavity of the tank. Furthermore, since the mixing plates and scraper plates are in contact with the inner wall of the tank during rotation, the asphalt residue remaining on the inner wall of the tank can be scraped off in time, avoiding the impact of residue adhering to the inner wall of the tank on the asphalt production efficiency, thus improving the practicality and versatility of the device.

Several discharge components 5 are fixedly and spaced apart on the lower part of the outer surface of the outer tank 1, facilitating the discharge of asphalt. An inner tank 6 is fixedly connected to the middle of the inner cavity of the outer tank 1. A heating mechanism 7 is installed and fixed in the gap between the outer surface of the inner tank 6 and the inner surface of the outer tank 1, enabling convenient... For heating the asphalt inside the inner tank 6, a rotating shaft 8 is rotatably connected to the middle of the inner cavity of the outer tank 1. The right end of the outer surface of the rotating shaft 8 is fixedly connected to the left output end of the motor 3. Several stirring mechanisms 9 are fixedly connected at intervals on the outer surface of the rotating shaft 8, which can facilitate the stirring of the asphalt. Several stirring mechanisms 9 are fixedly connected to the outside of the external connecting components 9, which can facilitate the connection of several scraping mechanisms 11. Several scraping mechanisms 11 are fixedly connected in a ring array on the side of each pair of connecting components 10 that are close to each other, which can achieve the function of fully stirring the asphalt and scraping off the residue adhering to the inner wall of the inner tank 6.

[0024] To achieve the goal of providing stable support for the external tank 1, please refer to... Figure 2 The support mechanism 2 includes a support frame 21. An arc-shaped base 22 is fixedly connected to the upper part of the outer surface of the support frame 21, which can connect and support the annular shell 23. The annular shell 23 is fixedly connected to the upper part of the outer surface of the arc-shaped base 22, and the inner surface of the annular shell 23 is fixedly connected to the outer surface of the outer tank 1.

[0025] For the purpose of facilitating the discharge of asphalt, please refer to... Figure 3 The discharge assembly 5 includes a discharge pipe 51, and a leak-proof plug 52 is slidably connected to the lower part of the inner cavity of the discharge pipe 51, which can prevent the asphalt in the inner cavity of the inner tank 6 from leaking to the outside.

[0026] To facilitate the mixing of asphalt, please refer to... Figure 3 The stirring mechanism 9 includes a fixed sleeve 91, and a plurality of stirring plates 92 are fixedly connected to the outer surface of the fixed sleeve 91 in a ring array. The inner surface of the fixed sleeve 91 is fixedly connected to the outer surface of the rotating shaft 8.

[0027] When motor 3 starts to drive, the left output end of motor 3 will drive the rotating shaft 8 to rotate, thereby driving several mixing plates 92 to fully mix the asphalt inside the inner tank 6.

[0028] For the purpose of facilitating the connection of several scraping mechanisms 11, see [reference needed]. Figure 4The connecting assembly 10 includes several connecting plates 101. Each pair of connecting plates 101 has an arc-shaped plate 102 fixedly connected to one side of each other on its outer surface. This can connect and fix adjacent transmission plates 111.

Figure 4 The scraping mechanism 11 includes a transmission plate 111. A scraper plate 112 is fixedly connected to the middle of the side of the outer surface of the transmission plate 111 away from the rotating shaft 8.

[0033] The working principle of this utility model is as follows: First, the heating tube 71 is driven to start heating, thereby heating the inner tank 6. After the asphalt is put into the inner cavity of the inner tank 6 through the feeding pipe 4, the power supply of the drive motor 3 is turned on, so that it drives several stirring plates 92 to start rotating through the rotating shaft 8, thereby fully stirring the asphalt in the inner cavity of the inner tank 6. At the same time, through the connection of several transmission plates 111 and scraper plates 112 with the corresponding arc plate 102, the scraper plates 112 and the stirring plates 92 can simultaneously and fully stir the asphalt in the inner cavity of the inner tank 6. Meanwhile, since the stirring plates 92 and the scraper plates 112 are all in contact with the inner wall of the inner tank 6, the stirring plates 92 and the scraper plates 112 can scrape off the residue remaining on the inner wall of the inner tank 6 in a timely manner during the rotation.
