The terms "comprises", "comprising", "includes", "including", "has", "having" and any variations thereof herein are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless otherwise specified, terms of degree such as "substantially", "approximately", "generally", "exactly", and "precisely" are used herein to mean "to a degree acceptable or appropriate under the circumstances in which the term is used" and not to exact numerical limits.

[0024] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that any of the embodiments described herein can be incorporated into any other embodiment.

[0025] The utility model embodiment provides a kind of asphalt production heat preservation device, as shown in Figures 1-5 As shown in the drawing, the asphalt production heat preservation device comprises:

[0026] Barrel 100, the barrel 100 inside is equipped with the storage area 101 of containing asphalt, the lateral wall of the barrel 100 is equipped with heating pipe chamber 102, the heat transfer conduit 300 is arranged inside the heating pipe chamber 102, the heat transfer conduit 300 is maintained by the circulating liquid circulating flow inside temperature stability, the lower head portion of the barrel 100 is equipped with containing cavity 103, the containing cavity 103 is stored for heating circulating liquid;The containing cavity 103 is equipped with heating unit for heating circulating liquid.

[0027] The circulating pump assembly comprises a circulating pump 400, a first three-way control valve 410 and a third three-way control valve 420, the heat transfer conduit 300, the first three-way control valve 410, the containing cavity 103, the third three-way control valve 420 and the circulating pump 400 are sequentially connected in series to form a main pipeline, and a bypass pipeline is further arranged to communicate between the first three-way control valve 410 and the third three-way control valve 420, so that the circulating liquid can be selected to be directly circulated or to pass through the containing cavity 103 to maintain the temperature of the circulating liquid by the heating unit;

[0028] When the circulating liquid flows in the main pipeline, which is usually used for the asphalt heating process, the circulating liquid transmits heat to the asphalt inside the cylinder 100 through heat conduction, and the containing cavity 103 replenishes the heat lost by the circulating liquid with the help of the heating unit to maintain the stability of the heat in the heating process.

[0029] When the temperature inside the cylinder 100 needs to be cooled and maintained, the circulating liquid will pass through the bypass pipeline to bypass the containing cavity 103, and a new circulating pipeline is formed by the added bypass pipeline. The circulating liquid in the new circulating pipeline loses external heat replenishment, and the heat loss of the circulating liquid during the circulation process is faster. Compared with natural cooling, the temperature drop of the cylinder 100 can be improved, and the temperature drop speed of different areas of the cylinder 100 during the cooling process can be maintained at the same amplitude. The separation of the additive components added to the asphalt inside due to uneven heat distribution, and the large amount of circulating liquid stored in the containing cavity 103 not participating in the circulation will help to accelerate the temperature drop of the cylinder 100, avoid the heat stored in the circulating liquid in the containing cavity 103 being exchanged into the cylinder 100 again during the circulation process, and affect the temperature drop efficiency of the cylinder 100. When the temperature is lower than the preset value, the bypass pipeline will be closed again to maintain the temperature stability by the main pipeline.
