Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 The present invention provides a technical solution: an emulsified asphalt production device that utilizes waste heat to preheat asphalt, comprising a base 10, a heating box 20, a motor 30, a rotating shaft 301, a stirring rod 302, a rotating rod 40, a scraper 401, a baffle 402, a clamping block 403, a rotating shaft 404, a belt 405, a discharge port 406, a stirring rod 407, a filter box 50, an air inlet pipe 501, an air outlet pipe 502, a heat preservation box 503, a heat conduction box 504, and a guide plate 505;

[0034] This emulsified asphalt production unit can utilize waste heat. The specific implementation method is as follows:

[0035] The heating chamber 20 has a heating mechanism on its surface, which includes: a filter box 50 connected to the surface of the heating chamber 20, an air inlet pipe 501 connected to the surface of the filter box 50, and the other end of the air inlet pipe 501 connected to the surface of the heating chamber 20; an air outlet pipe 502 installed on the surface of the filter box 50; a heat preservation box 503 installed on the surface of the base 10, and an air outlet pipe 502 fixedly connected to the surface of the heat preservation box 503; and a heat conduction box 504 embedded in the surface of the heat preservation box 503. A guide plate 505 is connected between the heat conduction boxes 504. The first rotating shaft 301 is rotatably connected to the heating box 20, and the heating box 20 is rotatably connected to the first stirring rod 302. The heat conduction boxes 504 are made of heat-conducting material, and the heat conduction boxes 504 are rotatably connected to the second rotating shaft 404.

The second rotating shaft 404 is located above the guide plate 505.

[0036] Heating chamber 20 heats the preheated asphalt inside. At this time, gas enters the interior of the inlet pipe 501 through heating chamber 20. The gas then enters the interior of filter chamber 50 through inlet pipe 501. The material inside filter chamber 50 filters the gas and adsorbs impurities. The gas then enters the outlet pipe 502 through filter chamber 502 and enters the interior of insulation chamber 503. Heat enters between insulation chamber 503 and heat conduction chamber 504. The heat between the gas and the surface of heat conduction chamber 504 heats heat heat conduction chamber 504. The gas then moves downward along guide plate 505 to the bottom of insulation chamber 503, and is discharged through exhaust port of heat conduction chamber 504. Heat conduction chamber 504 then transfers heat to the interior of asphalt inside heat conduction chamber 504, heating it.

[0037] The emulsified asphalt production device prevents the heating box 20 from accumulating during material feeding. The specific implementation method is as follows:

[0038] The base 10 is a plate structure, and a heating box 20 is fixedly connected to the surface of the base 10. A motor 30 is mounted on the surface of the heating box 20, and a rotating shaft 301 is rotatably mounted inside the heating box 20. The other end of the rotating shaft 301 passes through the heating box 20 and is connected to the motor 30. A stirring rod 302 is connected to the surface of the rotating shaft 301 and is located on the surface of the heating box 20. A rotating mechanism is provided inside the heating box 20, and the rotating mechanism includes: a discharge port 406 fixedly connected to the bottom of the heating box 20; a rotating rod 40 fixedly connected to the surface of the rotating shaft 301; a scraper 401 connected to the end of the rotating rod 40; and a baffle 402 rotatably mounted on the bottom surface of the discharge port 406. Furthermore, a locking block 403 is connected to the surface of the baffle 402, and the other end of the locking block 403 is inserted into the surface of the discharge port 406. A second rotating shaft 404 is rotatably installed inside the heat conduction box 504, and belts 405 are fitted onto the surfaces of the second rotating shaft 404 and the first rotating shaft 301. A second stirring rod 407 is fixedly connected to the surface of the first rotating shaft 301. One side of the baffle 402 is rotatably connected to the discharge port 406, and a locking block 403 is provided on the other side of the baffle 402. The locking block 403 is rotatably connected to the discharge port 406. The bottom of the rotating rod 40 is located inside the discharge port 406, and the end of the scraper 401 is in contact with the inner wall of the discharge port 406. The discharge port 406 and the scraper 401 are rotatably connected.

[0039] Start the motor 30, which drives the rotating shaft 301 to rotate, causing the rotating shaft 301 to rotate inside the heating box 20. The rotating shaft 301 drives the surface stirring rod 302 to rotate, causing the stirring rod 302 to stir the emulsified asphalt inside the heating box 20. The rotating shaft 301 drives the surface belt 405 to move through the surface transmission roller. At this time, the belt 405 drives the rotating shaft 404 to rotate through the transmission roller, causing the rotating shaft 404 to rotate inside the heat conduction box 504. The rotating shaft 404 drives the surface stirring rod 407 to rotate, causing the stirring rod 407 to mix the asphalt inside the heat conduction box 504.

[0040] When the material is being mixed and fed, the clamp 403 can be rotated to remove it from the surface of the feed port 406. At this time, the surface of the baffle 402 is no longer in contact with the feed port 406, and the baffle 402 is no longer blocking it. The material is discharged through the feed port 406, and the emulsified asphalt is discharged. At the same time, the rotating shaft 301 drives the rotating rod 40 to rotate, and the rotating rod 40 drives the scraper 401 on the surface to rotate. At this time, the scraper 401 rotates on the inner surface of the feed port 406, which can clean the inner wall of the feed port 406 and prevent the emulsified asphalt from being fixed inside the feed port 406 and causing blockage.

[0041] Working principle: When using this emulsified asphalt production device that utilizes waste heat to preheat asphalt, a filter box 50, an insulation box 503, a heat conduction box 504, and a guide plate 505 are set up to utilize waste heat. A rotating rod 40 and a scraper 401 are set up to prevent the heating box 20 from accumulating during material feeding, thus increasing the overall practicality.
