One end of the air inlet pipe 3 is fixedly connected to the stirring container 2 and communicates with the heating cavity 22. One end of the air outlet pipe 4 is fixedly connected to the stirring container 2 and communicates with the heating cavity 22. The opening and closing plate 5 is located below the stirring container 2. The opening and closing plate 5 is horizontally arranged and is slidably connected to the bracket 1 in the horizontal direction so that the opening and closing plate 5 can open and close the lower end of the stirring space 21.

The electric heating rod 10 can rotate relative to the stirring shaft 7.
[0028] A device for preparing phase change asphalt mixture provided by the utility model, compared with the prior art, the electric heating rod 10 is fixedly arranged on the vertical frame 6 through the fixing piece 110. The initial state of the opening and closing plate 5 is to close the lower end of the stirring space 21. Materials such as asphalt and phase change energy storage materials are put into the stirring space 21 through the upper end of the stirring space 21. The driving assembly 8 drives the stirring shaft 7 to rotate, so that a plurality of stirring blades 9 stir the materials in the stirring space 21. The air inlet pipe 3 is used to introduce steam, and the steam enters the heating cavity 22 through the air inlet pipe 3 and then flows out of the heating cavity 22 through the air outlet pipe 4. In this way, the heat of the steam heats the materials in the stirring space 21 from the surrounding to the middle through the side wall of the stirring space 21. The heat generated by the electric heating rod 10 heats the materials in the stirring space 21 from the middle to the surrounding through the stirring shaft 7.

When heating and stirring the phase change asphalt mixture, flue gas will be generated, and the flue gas needs to be filtered. The air extraction fan 1204 is started, and the rising flue gas in the stirring space 21 is drawn into the air suction pipe 1201, then enters the filtering cylinder 1202, and after being filtered by the filtering net 1203, it is discharged from the air outlet 12021 of the filtering cylinder 1202, and the filtered dust remains in the filtering cylinder 1202. When the dust in the filtering cylinder 1202 reaches a certain amount, the threaded connection between the end wall of the filtering cylinder 1202 and the air suction pipe 1201 is disconnected, so that the dust in the filtering cylinder 1202 can be handled.
