Description

Technical Field

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

[0002] Asphalt refers to a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is mainly used in industries such as coatings, plastics, rubber, and road paving. In the processing of asphalt, the raw materials for processing asphalt are mainly petroleum, oil sands, and hydrogenated refined agents. When processing asphalt, a variety of asphalt raw materials must be mixed. Therefore, a mixing tank for asphalt processing is needed.

[0003] For this purpose, a Chinese patent with publication number CN220425135U discloses a double-layer mixing tank for asphalt production and processing, including a first tank body and a conveying tank body, wherein a motor 1 is arranged on the right side of the outside of the first tank body, a rotating shaft 1 is fixedly connected to the output end of the motor 1, a driving wheel is fixedly connected to the outside of the rotating shaft 1, a driven wheel is arranged on the opposite side of the driving wheel, the driving wheel is rotatably connected to the driven wheel through a belt, a rotating shaft 2 is fixedly connected to the inside of the driven wheel, and a connecting rod 1 is fixedly connected to the outside of the rotating shaft 2. In the utility model, the asphalt raw materials inside the tank body are uniformly stirred, and the asphalt raw materials are prevented from settling inside the tank body, thereby improving the efficiency of production and processing and the product quality, thereby realizing the transportation of asphalt after production, avoiding the occurrence of the transportation pipe blockage phenomenon caused by the cooling and solidification of asphalt due to too slow transportation speed, and improving the working efficiency of the device.

[0004] However, in this patent, when the processed asphalt is discharged, some processed asphalt will remain on the inner wall of the tank to a certain extent. Since there is no scraping device inside the tank, the processed asphalt remaining on the inner wall of the tank to a certain extent cannot be scraped to the bottom of the tank, which will cause a certain degree of loss in the amount of processed asphalt discharged, resulting in a low utilization rate of the processed asphalt.
