Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of asphalt storage equipment, specifically an asphalt storage tank. Background Technology
[0002] With the continuous development of science and technology, asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, which is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and corrosion-resistant organic cementing material.
[0003] Current asphalt storage tanks generally cannot remove asphalt adhering to the tank walls when emptying asphalt, which affects the quality of asphalt in subsequent storage. To solve this technical problem, existing technology has proposed an asphalt storage tank, as disclosed in Chinese Patent [Application No. CN202320273225.9], which includes a tank body. The top of the tank body is connected to a first motor, and the first motor is rotatably connected to a rotating rod. The outer edge of the rotating rod is connected to a connecting shaft. The top of the rotating rod has a first heating groove, and the outer edge of the connecting shaft has a second heating groove. A stirring rod is connected to the outer edge of the connecting shaft. The inner part of the first heating groove... The tank has a heating rod connected to its wall, and a heating wire connected to its outer edge. Although this patent can heat the asphalt inside the tank by using the rotating rod and the first heating groove, as well as the second heating groove and the heating rod, ensuring that the asphalt inside the tank does not solidify and is difficult to pour out, and also uses the outer cylinder wall and the heating wire to provide auxiliary heating to the tank and keep the asphalt inside the tank warm, the above patent has certain defects in use. For example, in actual use, after a long period of use, a certain amount of asphalt will adhere to the scraper, connecting shaft and stirring rod. If it is not cleaned regularly, it will affect the quality of the asphalt stored next time. Utility Model Content

[0010] Preferably, the bottom of the tank is fixedly connected to a support leg, and the bottom of the tank is fixedly connected to a discharge pipe, which is equipped with a valve.
[0011] The beneficial effects of this utility model are as follows: When the asphalt storage tank provided by this utility model is needed, asphalt enters the tank through the inlet. The first motor is started to drive the stirring mechanism to stir the asphalt. Simultaneously, the asphalt is heated by an electric heating element, preventing it from easily solidifying and thus better preserving it. When the asphalt needs to be poured out, it is discharged through the discharge pipe. At the same time, the second motor is started to rotate the connecting mechanism, causing the lead screw to rotate and thus moving the scraper ring up and down, thereby cleaning the asphalt from the inner wall of the tank for subsequent use. If it is necessary to clean the stirring rod, stirring shaft, and scraper ring, the top cover is screwed off to separate it from the tank body. Then, the fixing nut is screwed off to separate the positioning post from the positioning hole, making it easy to remove the scraper ring for cleaning. Finally, the stirring rod is screwed off to separate it from the connecting frame, facilitating the cleaning of the stirring rod and stirring shaft. Attached Figure Description
