Currently, emulsified asphalt waterproof coatings are widely used in various building waterproofing projects due to their excellent waterproofing performance, convenient construction, and environmental friendliness. During the production process of emulsified asphalt waterproof coatings, heating devices are required to raise the raw materials to the required temperature for mixing with other raw materials.

[0003] Utility model patent CN221999581U discloses a heating device for raw materials of emulsified asphalt waterproof coating, belonging to the technical field of emulsified asphalt waterproof coating production.

Then, through the combined action of the scraping mechanism 8 and the stirring mechanism 7, the raw materials of the emulsified asphalt waterproof coating inside the mixing drum 2 are heated and stirred, and the raw materials adhering to the inner wall of the mixing drum 2 are scraped off.

[0027] like Figures 2 to 4 As shown, the stirring mechanism 7 includes: a fixed frame 9 fixedly connected to the top center of the stirring drum 2; a stirring shaft 10 rotatably connected to the bottom center of the fixed frame 9; the bottom end of the stirring shaft 10 penetrates the stirring drum 2 and extends into the interior of the stirring drum 2; a hollow tube 11 is sleeved on the outer surface of the stirring shaft 10 near the stirring drum 2; a first bevel gear 12 is fixedly connected to the top outer surface of the hollow tube 11; second bevel gears 13 mesh on both sides of the top of the first bevel gear 12; a first rotating shaft 14 is fixedly connected to the center of each of the two second bevel gears 13; the first rotating shaft 14 is located away from the second bevel gears 13.

The stirring blades 16 and the rectangular blades 18 stir the raw materials inside the stirring drum 2. At the same time, the heating tube 19 heats the raw materials inside the stirring drum 2 through the stirring drum 2, so that the raw materials are heated evenly. The temperature sensor 20 can detect the temperature inside the stirring drum 2 in real time. When the temperature reaches the set maximum threshold, it can automatically control the heating tube 19 to turn off.

[0029] like Figure 2 and Figure 5 As shown, the scraping mechanism 8 includes: a motor frame 21 fixedly connected to the side of the mixing drum 2 away from the feed inlet 5; a motor 22 fixedly connected to the top of the motor frame 21; a second rotating shaft 23 fixedly connected to the output end of the motor 22; the bottom end of the second rotating shaft 23 passing through the motor frame 21 and extending to the mixing drum 2; the second rotating shaft 23 rotatably connected to the motor frame 21 and the mixing drum 2; a first synchronous pulley 24 fixedly connected to the outer surface of the middle part of the second rotating shaft 23; a second synchronous pulley 26 connected to the first synchronous pulley 24 via a synchronous belt 25; the second synchronous pulley 26 fixed to the outer surface of the hollow tube 11; and the diameter of the first synchronous pulley 24 being larger than that of the second synchronous pulley 26. Scrapers are fixedly connected to both sides of the bottom end of the hollow tube 11. Plate 27, the bottom ends of both scrapers 27 are fixedly connected to rotating sleeve 28, rotating sleeve 28 is rotatably connected to stirring shaft 10, scraper 27 is adapted to stirring drum 2, start motor 22, the output end of motor 22 drives second rotating shaft 23, the second rotating shaft 23 rotates while driving first synchronous wheel 24, the first synchronous wheel 24 rotates while driving second synchronous wheel 26 to rotate rapidly through synchronous belt 25, the second synchronous wheel 26 rotates while driving hollow tube 11, the hollow tube 11 rotates while driving scraper 27, scraper 27 rotates on the outer surface of stirring shaft 10 through the cooperation of rotating sleeve 28, scraper 27 continuously scrapes off raw materials adhering to the inner wall of stirring drum 2 while rotating.

[0030] like Figure 3 As shown, a matching sealing ring 29 is fitted on the outer surface of the hollow tube 11 near the stirring cylinder 2. The sealing ring 29 is fixedly connected to the stirring cylinder 2, which improves the sealing performance at the connection between the hollow tube 11 and the stirring cylinder 2.

[0031] like Figure 1 As shown, the bottom four corners of the base plate 1 are all fixedly connected with casters 30 with braking function, which makes it convenient for users to push the device to move and fix it.

[0032] like Figure 1 As shown, a control box 31 with an internal touch screen is fixedly connected to one of the support frames 4 on the side away from the insulation cylinder 3, which makes it convenient for users to operate the device.

[0033] Working principle: The user pours the raw materials of the emulsified asphalt waterproof coating into the mixing drum 2 through the inlet 5, and then starts the motor 22 and the heating tube 19. The output end of the motor 22 drives the second rotating shaft 23. The rotation of the second rotating shaft 23 drives the first synchronous pulley 24. The rotation of the first synchronous pulley 24 drives the second synchronous pulley 26 to rotate rapidly through the synchronous belt 25. The rotation of the second synchronous pulley 26 drives the hollow tube 11. The rotation of the hollow tube 11 drives the scraper 27. The scraper 27 rotates on the outer surface of the mixing shaft 10 through the cooperation of the rotating sleeve 28. As the scraper 27 rotates, it continuously scrapes the surface of the mixing shaft 10. The raw materials adhering to the inner wall of the mixing drum 2 are scraped off, allowing for rapid reverse heating and stirring of the raw materials near the inner wall and at the center of the device. This ensures uniform heating of the raw materials, improves the heating effect, and consequently enhances the processing efficiency. Furthermore, the rapid rotation of the hollow tube 11 drives the first bevel gear 12, which in turn drives the second bevel gears 13 on both sides. The second bevel gears 13 rotate within the fixed frame 9 via the first rotating shaft 14. Simultaneously, the rotation of the second bevel gears 13 drives the third bevel gear 15, which in turn drives... The stirring shaft 10 rotates, driving the stirring blades 16 and the rotating disk 17. The rotating disk 17 drives the rectangular blades 18. While the stirring blades 16 and 18 stir the raw materials inside the stirring drum 2, the heating tube 19 heats the raw materials inside the stirring drum 2, ensuring uniform heating. The temperature sensor 20 can detect the temperature inside the stirring drum 2 in real time. When the temperature reaches the set maximum threshold, the heating tube 19 can be automatically shut off. This allows for the simultaneous heating and stirring of the raw materials for emulsified asphalt waterproof coating, while also scraping off the raw materials adhering to the inner wall of the device. This avoids a large amount of raw materials adhering to the inner wall and causing waste, thus improving the utilization rate of raw materials. This solves the problem that while existing heating devices for emulsified asphalt waterproof coating raw materials can stir and heat them, the raw materials have a certain viscosity, resulting in a large amount of raw materials adhering to the inner wall of the device during heating and stirring. Furthermore, these devices cannot simultaneously heat and stir the raw materials inside the device and scrape off the raw materials adhering to the inner wall, easily leading to a large amount of waste.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
