Background
The modified asphalt is an asphalt binder prepared by adding external additives (modifiers) such as rubber, resin, high molecular polymer, ground rubber powder or other fillers or by adopting measures such as mild oxidation processing of asphalt and the like, so that the performance of the asphalt or the asphalt mixture is improved. The SBS modified asphalt is polymer modified asphalt, which is prepared with base asphalt as material and SBS modifier in certain proportion, and through shearing, stirring and other steps, SBS is dispersed homogeneously in asphalt while adding special stabilizer in certain proportion to form SBS blending material, and the excellent physical performance of SBS is utilized to modify asphalt.
SBS is known collectively as thermoplastic styrene-butadiene rubber and is commercially available as small particles in the form of white or pale yellow porous strands or flakes that are typically supplied to asphalt manufacturers.
With the continuous progress of the technology, the grinding performance of the colloid mill is enhanced, the swelling time of the SBS after being put into the matrix asphalt can be greatly shortened, fig. 1 is a schematic diagram of the structural principle of a swelling tank used in the existing SBS modified asphalt production line, referring to fig. 1, the existing swelling tank 1 comprises a tank body 11, a matrix asphalt inlet pipe 12 and an SBS raw material putting port 13 are arranged at the top of the tank body 11, stirring blades 14 are arranged in the tank body 11, and an asphalt outlet pipe 15 communicated with the colloid mill (not shown in the figure) is arranged at the bottom of the tank body 11. In production, after the base asphalt heated to about 200 ° enters the tank body 11 through the base asphalt inlet pipe 12, SBS conveyed by a lifter (not shown in the figure) also falls into the tank body 11 from the SBS raw material feeding port 13, and then is mixed and stirred by the stirring blade 14, that is, conveyed to a colloid mill (not shown in the figure) through the asphalt outlet pipe 15 for grinding, and then conveyed to a finished product tank after grinding.
When the swelling tank shown in fig. 1 is used for production, the flow rate of asphalt needs to be controlled by the pump body on the pipeline before the base asphalt inlet pipe 12 and the pump body on the pipeline after the asphalt outlet pipe 15, and the asphalt liquid level in the tank body 11 needs to be kept near one third of the position of the tank body 11, so that the purpose of this is to prevent the performance change caused by overlong mixing time of SBS in high-temperature asphalt, and to adjust the feeding amount by the rotating speed of the elevator because SBS is mostly packaged in the form of woven bags and poured into the elevator by breaking the bags manually. Therefore, the woven bag fragments and other impurities are inevitably brought in, so the top of the tank body 11 is usually required to be provided with an open observation operation port (not shown in the figure) for manually fishing out the impurities entering the tank body 11, for example, if the asphalt liquid level is too high, or the stirring blade 14 rotates too fast, the high-temperature asphalt is easily splashed out of the tank body 11. The asphalt level in the can body 11 needs to be controlled. However, the space utilization efficiency of the can body 11 is low. Usually, the height of the tank body 11 is 1-1.5 m, the diameter is about 60cm, therefore, the stirring blade 14 and the matching motor are also manufactured by customization, and the stirring blade 14 belongs to a moving part, so that maintenance and/or replacement are needed in the operation period, and the operation cost is high.
