[0001] The utility model relates to the technical field of asphalt heating tanks, in particular to a heating tank for emulsified asphalt. Background Art

[0002] Asphalt heating tank is a device used to heat and store asphalt, usually used in asphalt pavement construction and maintenance projects. Asphalt heating tank is mainly composed of tank body, heating device, stirring device, stirring blade, temperature sensor, control system, etc. Emulsified asphalt is a stable emulsion liquid mixed with asphalt, water and emulsifier through mechanical shearing and stirring processes. The heating device usually uses a heating rod or heating wire, which is set on the inner wall of the tank body. The spray and stirring device are evenly heated. The asphalt is left to cool into a solid state and cannot be used.

[0003] In the prior art, a Chinese patent with authorization announcement number N212128734U discloses an asphalt heating tank, which belongs to the field of asphalt heating tanks. Its technical points include a tank body, the tank body includes an inner layer and an outer layer, a heating wire is arranged between the inner layer and the outer layer, a cover plate is arranged on the top of the tank body, and a bottom plate is arranged on the bottom of the tank body. An asphalt input pipe body is installed on the cover plate, one end of the asphalt input pipe body extends downward to the inside of the tank body, and the other end is provided with a first sealing cover body, a screw drive motor is also installed on the cover plate, a scraper is installed on the drive rod of the screw drive motor, and a plurality of through holes are opened on the scraper; a plurality of heating rods are also arranged inside the tank body, one end of the heating rod is fixed on the cover plate, and the other end is fixed on the bottom plate after passing through the scraper, and the plurality of heating rods are evenly distributed inside the tank body; an asphalt heating tank of the utility model makes the asphalt more evenly heated when heated and liquefied, and will not adhere to the tank wall.

[0004] At present, most asphalt heating tanks on the market still have certain shortcomings when in use. As shown in the above-mentioned document, the device is provided with a number of heating rods to make the asphalt heated more evenly, which can reduce the occurrence of solid asphalt during use and reduce the possibility of blockage at the discharge port. However, the stirring device of the heating tank may need to be replaced with different types of stirring rods before use, or the original stirring rod cannot be used and needs to be disassembled and replaced. The traditional method of disassembling the stirring rod is to unscrew the object through a thread, which is cumbersome and time-consuming to operate, affects the use of the device, and reduces the heating efficiency of the device. Secondly, the vibration generated when the heating tank stirs asphalt or moves the tank body will increase the wear of the internal parts of the tank body, which may cause the internal parts to loosen, reduce the service life of the device, and is cumbersome to use. The existing structure needs to be improved. Utility Model Content
