Preparation equipment and preparation method of binder asphalt

Abstract

The invention relates to the technical field of asphalt, in particular to preparation equipment and a preparation method of binder asphalt, and the preparation equipment comprises a box body, a box cover, a fixed plate, an air outlet, a stirrer and a heating resistor; the box body is in a cuboid shape, a fixing plate is fixedly connected to the edge of the side face of the box body, a liquid outlet is formed in the bottom of the box body, and a rectangular groove is formed in the box body. The device further comprises a defoaming unit and a collecting unit; the defoaming unit is used for treating floating foam on the surface of binder asphalt; the collecting unit is used for collecting floating foam of the defoaming unit; a rectangular through hole is formed in the position, close to the collecting unit, of the box body. The defoaming unit is used for scraping floating foam on the surface of the medium-temperature asphalt, and the collecting unit is used for collecting the floating foam on the surface, so that the floating foam on the surface of the medium-temperature asphalt is scraped into the collecting box, the situation that the floating foam enters the medium-temperature asphalt again, and the quality of the finally prepared binder asphalt is affected is reduced, and therefore the device has reasonability and is suitable for popularization and application. The method has a practical application effect.

Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to a preparation equipment and method for binder asphalt. Background technique [0002] The main performance indicators of binder asphalt include softening point, quinoline insoluble matter, toluene insoluble matter, coking value, ash, moisture, sodium ion content and mesophase content. When coke is mixed and kneaded, it needs to be well wetted with aggregate coke on the surface of the coke, and can be immersed into the voids of the coke, that is, good penetration performance. In addition, it needs to have a high carbonization yield, that is, the coking value. The higher the coking value, the higher the carbonization yield of the formed composite material during firing, the higher the bulk density of the material, and the greater the mechanical strength, the lower the resistivity of the material, so that the consumption and The lower the cost, the binder asphalt is usually produced...

Problems solved by technology

[0003] For example, a Chinese patent with the application number CN201821570744.7 discloses a modified asphalt preparation equipment, including a device body, a base, a heat-conducting pipe, and a stirring tank. The device body includes a shell and an insulation layer, and the shell is sleeved On the outside of the stirring tank, a heat-conducting pipe and an insulation layer for insulating the heat-conducting pipe are arranged between the stirring tank and the shell. The shell is plugged with a heat-conducting liquid outlet pipe and a heat-conducting liquid inlet pipe. The heat-conducting liquid The outlet pipe and the heat-conducting liquid inlet pipe communicate with the heat-conducting pipe through the heat-conducting liquid outlet and the heat-conducting liquid inlet. The feed inlet, the base supports and fixes the device body at its top end. This technical solution has the advantages of reasonable design, simple operation, convenient overall heating of the stirring tank and reduction of adhesion; but this technical solution cannot The froth of modified asphalt is processed, which will affect the final quality of modified asphalt, resulting in the limitation of this scheme
