Adding device of bi-component asphalt additive

Abstract

The invention discloses an adding device of a bi-component asphalt additive. The adding device comprises a stirring tank, reagent storage tanks and quantifying tanks, the stirring tank is communicatedwith the two quantifying tanks through pipelines, each quantifying tank is communicated with the corresponding reagent storage tank through a pump body, a stirring mechanism is arranged on the stirring tank, and the two reagent storage tanks are used for storing two asphalt modifiers respectively. According to the invention, two components of the asphalt modifier are separately added; the stirring tank is used for improving the stirring uniformity; the two components of the modifier can be fully and uniformly mixed and reacted, the adding proportion of the two-component asphalt modifier can be accurately controlled, and the problem that in the existing asphalt concrete production process, the adding proportion of a two-component asphalt additive is not accurately controlled, and consequently the performance of an asphalt mixture is unstable is solved.

Description

technical field [0001] The invention relates to the technical field of asphalt mixing equipment, in particular to a device for adding two-component asphalt additives. Background technique [0002] With the continuous development of asphalt pavement materials in my country, the emergence of various asphalt modifiers has greatly improved the performance of ordinary petroleum asphalt, and improved the performance and service life of asphalt pavement. However, some asphalt modifiers are not added to the base asphalt in advance, and need to be mixed with the base asphalt into the aggregate during the production of asphalt mixture, which brings certain difficulties to the production of asphalt mixture. At present, most asphalt modifiers are single-component. In the process of asphalt mixture production, most of the mixture production units add a channel in the mixing station, add the modifier into the mixing pot, and mix with the asphalt . But for the two-component asphalt modif...

AI Technical Summary

Problems solved by technology

However, due to factors such as the control accuracy of the motor itself and the blockage of the delivery pipeline, the proportion of the components that actually enter the mixing pot often does not meet the preset requirements, resulting in a greatly reduced modification effect of the two-component modifier.
