[0028] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, below will be combined with the further detailed introduction of the utility model to the drawing.

[0029] The utility model provides a kind of heating device with temperature control mechanism for liquid phase asphalt dissolution as shown in Figures 1-6

[0031] Heating mechanism 4 is arranged outside heating tank 3, for asphalt heating, and heating mechanism 4 includes heat conducting oil tank 401, heat conducting oil tank 401 is fixed at the right side of heating shell 1, electric heating 402 is fixedly provided at one side inside heat conducting oil tank 401, circulating pump 403 is fixedly provided above heat conducting oil tank 401, conveying pipe 404 is fixedly connected to the other end of circulating pump 403, and pipeline 405 is fixedly connected to the other end of conveying pipe 404.

When the asphalt is heated, the temperature sensor 5 is used to monitor the temperature of the asphalt in real time. The temperature sensor 5 should have the characteristics of high precision and fast response, so as to accurately reflect the actual temperature of the asphalt. When the temperature sensor 5 senses that the temperature exceeds the set temperature, the temperature sensor 5 will transmit a signal to the controller 2, and the controller 2 controls the on-off of the electric heating 402 and the circulating pump 403, so as to ensure temperature control.

[0037] As shown in Figure 4 and Figure 5 The two sides of the transmission rod 802 are fixedly connected with connecting sleeve rods 804, the inside of the connecting sleeve rods 804 is fixedly provided with springs 805, the outside of the springs 805 is fixedly connected with top blocks 806, the rear side of the top blocks 806 is fixedly connected with telescopic rods 807, the outer end of the telescopic rods 807 is fixedly connected with scrapers 808, when the transmission rod 802 rotates, the outside connecting sleeve rods 804, telescopic rods 807 and scrapers 808 are scraped in the inner wall of the heating tank 3, so that the asphalt residues left on the inner wall are avoided, and the rear side of the telescopic rods 807 is pushed by the spring 805 inside the connecting sleeve rod 804 to rebound and extrude, so that the scraper 808 can tightly adhere to the inner wall of the scraper 808, and the scraping effect is improved.
