Asphalt mixing system

Abstract

The invention provides an asphalt mixing system. The asphalt mixing system comprises a pot body, a feeding door, a discharging door, a mixing device and a heating device, wherein the feeding door is arranged at the upper right of the pot body, and the discharging door is arranged at the lower right of the pot body; a liner plate is arranged on the inner wall of the pot body, and a motor is arranged at the upper end of the pot body; the mixing device consisting of a mixing shaft and mixing blades is arranged in the pot body; the mixing shaft is connected to the motor; the mixing blades which are uniformly distributed are arranged on the mixing shaft, and the adjacent mixing blades are different in transverse length; the heating device, comprising solenoid coil sets, thermal insulation sleeves and a controller, is arranged on the outer surface of the pot body; a plurality of solenoid coil sets are uniformly arranged around the outer wall of the pot body, and the thermal insulation sleeves are arranged at the outer sides of the solenoid coil sets; the controller is connected to the solenoid coil sets. The asphalt mixing system is simple in structure, and uniform to mix, and can prevent a mixture from adhering.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an asphalt mixing system. Background technique [0002] In modern traffic, large flow, heavy load, high speed, and environmental differences in different places have put forward higher requirements for asphalt pavement, such as high temperature stability, low temperature crack resistance, anti-aging, anti-fatigue, anti-peeling ability, easy maintenance Wait. In order to meet this requirement, asphalt must be modified to improve the rheological properties of asphalt, improve the adhesion between asphalt and aggregate, and prolong the durability of asphalt. It meets different usage requirements. The admixture and asphalt need to be mixed and compatible at a certain high temperature. At the same time, with the continuous addition of the admixture, continuous stirring is required to make the admixture and asphalt fully mixed. [0003] With the extensive development of various...

Problems solved by technology

However, in the actual industrial production process, the addition amount and addition speed of other materials are relatively large. With the continuous addition of other materials, the temperature of asphalt will drop rapidly by about 20-30°C, which will cause the asphalt mixture to stick. , resulting in uneven stirring, and even the stirring cannot continue
