Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1-2, the directly-heated asphalt tank for spreading vehicles comprises a heating mechanism arranged in a tank body 1, wherein the heating mechanism is arranged in the tank body 1 for rotating, the heating mechanism comprises a rotating shaft 2 and blades 5 arranged on the rotating shaft 2, the rotating shaft 2 is arranged along the axis direction of the tank body 1 and rotates in the tank body 1, a heating device is arranged in the rotating shaft 2, the part of the rotating shaft 2 extending out of the tank body 1 is provided with an air inlet 3, and the air inlet 3 is communicated with an air compressor. Heating device directly heats pivot 2, utilizes the heat heating of pivot 2 to jar pitch in the body 1, and 2 rotations of pivot in the heating process drive blade 5 stir pitch, can make the pitch homoenergetic of the different degree of depth heated like this for the pitch heating is more even. Simultaneously in order to reduce the risk that pitch adheres to on blade 5, set up gas outlet 6 on blade 5, gas outlet 6 is first gas simultaneously when blade 5 stirs, blow pitch, avoid the pitch adhesion on blade 5, and gas passage directly sets up in pivot 2, therefore can heat gas through heating device, utilize the air after the heating to avoid the pitch adhesion on blade 5 on the one hand, on the other hand can preheat pitch, make pitch heat to appointed temperature rapider.
The rotating shaft 2 is hollow, the heating device is arranged in the rotating shaft 2, and the rotating shaft 2 is a gas channel.
The blade 5 is fixed on the rotating shaft 2 and a cavity is arranged in the blade 5, the blade 5 is communicated with the rotating shaft 2, and a plurality of air outlets 6 are arranged on the surface of the blade 5.
