Heating spacer 5 is including communicating first heating jacket 5a, transfer tube 5b and second heating jacket 5c in proper order, first heating jacket 5a cover is located the outside of second output portion 3b, second heating jacket 5c cover is located the outside of third output portion 3c, second heating branch pipe 7 with first heating jacket 5a intercommunication, outer flow tube 8 with second heating jacket 5c communicates with each other.

The second heating branch pipe 7 is connected to the bottom of the first heating jacket 5a, and the transfer pipe 5b is connected to the top of the first heating jacket 5 a. A spiral first guide sheet 9 is arranged in the inner cavity of the first heating sleeve 5a, and two sides of each position of the first guide sheet 9 are connected with the inner wall of the first heating sleeve 5 a. A spiral second guide piece 10 is arranged in the inner cavity of the second heating sleeve 5c, and two sides of each position of the second guide piece 10 are connected with the inner wall of the second heating sleeve 5 c. And heat preservation layers 11 are arranged on the outer walls of the heating pipe 4, the first heating sleeve 5a and the second heating sleeve 5 c.

The first heating branch pipe 6 is provided with a first control valve 12, and the second heating branch pipe 7 is provided with a second control valve 13. The heating device further comprises a flushing header pipe 14, a third control valve 15 is arranged on the flushing header pipe 14, two flushing branch pipes 16 are arranged at the downstream end of the flushing header pipe 14, which is located at the third control valve 15, in a communicating manner, the two flushing branch pipes 16 are respectively communicated with the first heating branch pipe 6 and the second heating branch pipe 7, and the flushing branch pipes 16 are communicated with the first heating branch pipe 6 at the downstream of the first control valve 12 or the second heating branch pipe 7 at the downstream of the second control valve 13.

When heating the asphalt in the asphalt tank 1, firstly, a heating medium is input through the heating medium input pipe 2, and the heating medium respectively flows into the heating pipe 4 and the heating spacer 5 through the first heating branch pipe 6 and the second heating branch pipe 7, so that the asphalt tank 1 and the output pipe 3 are heated; therefore, the asphalt tank 1 can be heated only by one heat medium input pipe 2, and the output pipe 3 is heated, so that the investment of equipment is saved.

Furthermore, in practical use, the diameters of the first heating branch pipe 6 and the second heating branch pipe can be selected according to specific flow requirements, so that the flow rates in the asphalt tank 1 and the heating spacer 5 can be controlled, more heating is required outside the asphalt tank 1, and the output pipe 3 is lower in demand, so that the diameter of the first heating branch pipe 6 can be set to be larger than that of the second heating branch pipe 7.

Meanwhile, in actual use, if the temperature of the asphalt is low, the second control valve 13 and the valve on the first output part 3a are closed; then only the first heating branch pipe 6 and the heating pipe 4 heat the asphalt; when the temperature of the asphalt reaches a certain temperature, the valve on the first output part 3a and the second control valve 13 are opened, so that the output pipe 3 can be heated in time.

The heating medium in the second heating branch pipe 7 firstly flows into the first heating jacket 5a, and then flows into the second heating jacket 5c through the transfer pipe 5b, so that the second output part and the third output part 3c can be heated and insulated, and the temperature of the asphalt is ensured (the first output part 3a is short in length, can be buried in the insulating layer 11, and the heat loss of the first output part can be ignored). Wherein the temperature change of the whole output pipe 3 is large before and after the flow of the asphalt, so that the second output part 3b can deform to a certain extent, thereby better preventing the output pipe 3 from deforming or even being damaged. Meanwhile, the first heating jacket 5a and the second output part 3b are in a bonding state rather than being fixedly connected, so that the first heating jacket 5a can not influence the deformation of the second output part 3 b.

When the heat medium flows in the first heating sleeve 5a and the second heating sleeve 5c, under the guiding action of the first guide piece 9 and the second guide piece 10, the heat medium flows spirally, so that the heat preservation and heating actions of the heat medium on the whole output pipe 3 are increased, the output pipes 3 with different heights and positions can be well preserved, the heat preservation effect is good, and the conveying quality of the asphalt is also guaranteed. The heating medium in the second heating jacket 5c flows out through the outflow pipe 8 and circulates, namely is conveyed to the heating station and then is heated for recycling.

After the heating pipe is used for a certain time, the heating pipe 4 and the heating spacer 5 are usually required to be cleaned periodically; at this time, the heating pipe 4 and the heating spacer 5 can be flushed respectively through the two flushing branch pipes 16 only by closing the first control valve 12 and the second control valve 13, then opening the third control valve 15, and inputting flushing liquid through the flushing main pipe 14, which is simple and convenient. The third control valve 15 is in a closed state when the asphalt is normally heated.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
