Figures 1-5 The application will be described below in detail:

[0025] A rapid heating device for modified asphalt production, comprising:

[0026] A heating bin 1, four corners at the bottom of the heating bin 1 are provided with electric heating rods 2, and the heating ends of the electric heating rods 2 extend into the interior of the heating bin 1;

[0029] An air supply assembly 5 is arranged outside the heating bin 1, the air supply assembly 5 is used for supplying hot air into the installation pipe 4, and the air supply assembly 5 comprises a high-temperature air pump 501 arranged on the side wall of the heating bin 1, the air inlet end of the high-temperature air pump 501 is communicated with the interior of the heating bin 1, a cylinder cover 502 is fixedly arranged at the bottom of the stirring tank 3, the air outlet end of the high-temperature air pump 501 is communicated with the bottom of the cylinder cover 502, the top side of the heating bin 1 is communicated with a flow guide pipe 503, the other end of the flow guide pipe 503 is communicated with a connecting cylinder 504, and the upper end of the installation pipe 4 is rotatably connected with the connecting cylinder 504 through a sealing bearing.

[0030] Working process description:

[0031] Preparation stage: the modified asphalt raw material is added into the stirring tank 3 through the feeding hopper 301;

[0032] Heating start: the electric heating rods 2 are started, the gas temperature in the interior of the heating bin 1 is increased, the high-temperature air pump 501 is started, the high-temperature air pump 501 extracts hot air from the interior of the heating bin 1, the hot air enters the interior of the installation pipe 4 through the cylinder cover 502, in the interior of the installation pipe 4, the high-temperature gas exchanges heat with the asphalt in the interior of the stirring tank 3, then the cooled gas returns to the interior of the heating bin 1 through the flow guide pipe 503;

[0033] Discharge: when the modified asphalt reaches the required temperature and mixing degree, open the valve of the discharge pipe 302 to discharge the modified asphalt out of the stirring tank 3, and complete the entire production process.

[0034] The rapid heating device for modified asphalt production can heat the asphalt inside and outside at the same time by placing the stirring tank 3 inside the heating bin 1 and setting the ventilation assembly 5 to pass the high-temperature gas inside the heating bin 1 into the installation pipe 4 inside the stirring pipe body. In this way, the asphalt can be heated quickly and uniformly compared with the traditional heating method, the heating time is shortened, the production efficiency is improved, and the quality of the modified asphalt produced is more stable and reliable. At the same time, the device can more effectively utilize energy, reduce energy waste and environmental pollution.

[0035] As shown in Figure 5 In some embodiments, a pressure relief valve 505 is installed on the pipe body of the flow guide pipe 503. More specifically, during the production of modified asphalt, the gas inside the heating bin 1 may expand as the temperature rises, causing the pressure to rise. The pressure relief valve 505 can ensure that when the pressure inside the heating bin 1 exceeds a certain set value, the valve will automatically open to release excess pressure, thereby keeping the pressure inside the heating bin 1 stable. The presence of the pressure relief valve 505 can also indirectly improve production efficiency. When the pressure inside the heating bin 1 remains stable, the heating and mixing process of the modified asphalt will be more uniform and efficient. This helps to shorten the production cycle and improve product quality.

[0036] As shown in Figure 4 In some embodiments, the installation pipe 4 inside the stirring tank 3 is spiral-shaped. More specifically, the spiral-shaped pipe design ensures that the hot gas entering the stirring tank 3 can be uniformly distributed inside the entire tank body, avoiding the occurrence of local overheating or overcooling. This uniform heating method helps to ensure the quality and stability of the modified asphalt.

[0037] As shown in Figure 1As shown, in some embodiments, further comprising a driving member 6 arranged above one side of the heating bin 1, the driving member 6 is used to drive the rotating of the mounting pipe 4, the driving member 6 comprises a driving motor 601 fixed above the side wall of the heating bin 1, the output shaft of the driving motor 601 is connected with a driving pulley 602, the upper side of the pipe body of the mounting pipe 4 is fixed with a driven pulley 603, and the driving pulley 602 and the driven pulley 603 are transmissionally connected with a transmission belt 604, more specifically, the main function of the driving member 6 is to drive the rotating of the mounting pipe 4 in the stirring tank 3, so as to realize the efficient stirring and mixing of the modified asphalt. By rotating the mounting pipe 4, the driving member 6 can promote the uniform distribution of heat in the stirring tank 3, improve the heating efficiency and mixing effect of the modified asphalt, so as to ensure the stability and consistency of the product quality, the working principle is that the driving motor 601 drives the rotating of the driving pulley 602, when the driving pulley 602 rotates, the driven pulley 603 rotates under the transmission of the transmission belt 604, so as to drive the rotating of the mounting pipe 4 in the stirring tank 3, it should be noted that the driving member 6 cannot be used at the beginning, and it needs to be used after the asphalt in the stirring tank 3 is melted to a certain degree.
