Description

Technical Field

[0001] The utility model relates to the technical field of asphalt, in particular to an asphalt storage tank for road construction. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly existing in the form of liquid or semi-solid petroleum, with a black surface, soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosive organic cementing material, which can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground, some forming ore layers or accumulating on the earth's crust surface. Asphalt is mainly used in industries such as coatings, plastics, rubber, etc. and for paving roads.

[0003] For example, in the Chinese patent with the publication number CN207360989U, an asphalt storage device is proposed. In this patent, the controller is used to turn on the heater. After the heater is turned on, the temperature of the heat-conducting oil in the outer cylinder will rise rapidly. At this time, the asphalt in the inner cylinder will quickly melt under the high temperature of the heat-conducting oil. Then, refer to the reading on the weighing device, and the controller is used to open the solenoid valve. When the reading on the weighing device drops to the preset value, immediately close the solenoid valve, and the sampling is completed, that is, the preset amount of asphalt is obtained. In addition, the inner cylinder is detachably installed in the outer cylinder, and the staff can regularly remove the inner cylinder to clean the inner walls of the inner cylinder and the outer cylinder. However, in this solution, since the asphalt in the inner cylinder is stirred by the spiral stirring blades, and asphalt has strong viscosity, the asphalt sticking to the inner wall of the inner cylinder may not be easily contacted by the spiral stirring blades when heated and discharged, and then the asphalt on the inner wall of the inner cylinder may not be easily discharged, which may affect the subsequent use effect of the inner cylinder.
