TECHNICAL FIELD
[0001] The utility model relates to the technical field of asphalt processing, especially to a mixed asphalt heating tank. BACKGROUND
[0002] In the field of infrastructure construction that is booming today, asphalt, as a key road-building material, its processing efficiency and accuracy are crucial to ensuring project quality and progress. As the core equipment in the asphalt processing process, the performance of the asphalt heating tank directly affects the quality of the final asphalt product and the efficiency of the entire production operation.
[0003] Traditional asphalt heating tanks have certain limitations in structure and function. The heating method is relatively single, generally only heating elements such as heat-conducting oil heating coil or electric heating wire are arranged at the bottom or sidewall of the tank. This single heating layout leads to uneven heating of the asphalt in the tank. During the heating process, heat is mainly transferred from the location of the heating element to the surrounding area. The asphalt near the heating element can quickly absorb heat and the temperature rises rapidly; while the asphalt far from the heating element is heated slowly, forming a large temperature gradient.
[0004] However, this heating method of traditional asphalt heating tanks leads to insufficient and uneven heating of asphalt, ultimately causing a series of problems. Due to frequent local overheating, the asphalt in the overheated area may age and deteriorate, changing its physical and chemical properties, and thus affecting the durability and stability of the road after paving. At the same time, uneven heating results in low overall heating efficiency, requiring more energy to achieve the desired heating effect, increasing production costs. Moreover, asphalt is prone to adhere to the tank wall during the heating process, forming thick residues over time. These residues not only affect the heating and stirring effect, but also hinder heat transfer, further exacerbating uneven heating, shortening the service life of the heating tank, and increasing the frequency and cost of equipment maintenance and cleaning.
