[0014] like Figures 1 to 3 As shown, a heating storage tank for rubber asphalt includes a support base 1, a support leg 2 is installed at the bottom of the support base 1, a tank body 3 is installed on the top of the support base 1 via a rotating device, the tank body 3 is a double-layer structure, a serpentine heating pipe 4 is provided in the interlayer of the tank body 3, the rotating device includes a slewing bearing 5, the inner ring of the slewing bearing 5 is fixedly mounted on the top of the support base 1 via a flange 6, the outer ring gear of the slewing bearing 5 is meshed with a driving gear 7, and the driving gear 7 is mounted on the driving shaft of a drive motor 8, a flange 6 is installed at the bottom of the tank body 3, the bottom of the flange 6 is connected to the top of the outer ring gear of the slewing bearing 5, and a cleaning device is provided in the tank body 3;

[0015] Specifically, the serpentine heating tube 4 heats up the asphalt in the tank body 3 so that it is not easy to solidify. The drive motor 8 is started, driving the driving gear 7 to rotate, and the outer ring gear of the slewing bearing 5 meshing with the driving gear 7 rotates, driving the tank body 3 to rotate, thereby causing the asphalt to rotate and not easy to solidify. A cleaning device is also provided in the tank body 3 to clean it.

[0016] The cleaning device includes a driving motor 29 installed on the top of the tank body 3. A screw 10 is connected to the driving shaft of the driving motor 29. The screw 10 extends downward into the tank body 3. The bottom of the screw 10 is rotatably connected to the bottom of the tank body 3. An external thread is provided on the screw 10. A connecting ring 11 is threadedly connected to the screw 10. Several support rods 12 are distributed on the outer circumference of the connecting ring 11. The outer end of the support rod 12 is connected to a connecting ring 2 13. The connecting ring 2 13 is a cavity structure. Several nozzles 14 are distributed on the outer circumference of the connecting ring 2 13.

[0017] Specifically, when cleaning is required, the drive motor 2 9 is started, driving the screw 10 to rotate, and the connecting ring 11 threadedly connected to the screw 10 moves up and down along the screw 10, driving the connecting ring 2 13 to move up and down asphalt cleaning liquid is sprayed from the nozzle 14 to clean the inner wall of the tank body 3, and finally discharged from the discharge pipe 20.
