The utility model discloses a modified
asphalt constant-temperature storage anti-
caking device, and belongs to the technical field of
asphalt storage. The modified
pitch constant-temperature storage anti-
caking device comprises a closed
storage tank, a central shaft, a
spiral blade, a heat conduction plate, an annular heating cavity and a heat preservation shell. The central shaft is connected with the
storage tank through a bearing;
helical blades are arranged on the outer side of the central shaft; the heat-conducting plate is fixed on the inner wall of the
storage tank; the surface corrugated groove design improves the heat conduction efficiency; an
electric heating wire is arranged in the annular heating cavity and is connected with a heat-conducting oil circulating
system, so that the heating uniformity is ensured; the heat preservation shell is provided with adjustable heat dissipation holes, and
dynamic balance of the temperature is achieved. The modified
asphalt constant-temperature storage device can effectively prevent the
caking problem caused by uneven heating or local cooling of asphalt, has the characteristics of compact structure,
high heat conduction efficiency and high practicability, and is suitable for constant-temperature storage of modified asphalt.
