A New Type of High Temperature Asphalt Cold Filling System

Abstract

The invention discloses a novel high-temperature asphalt cold filling system, and relates to the technical field of asphalt cold filling equipment. The novel high-temperature asphalt cold filling system comprises a first hydraulic piston pump, a hydraulic station, a first heat exchanger, a first cooling tower, air blowers, filling machines, a second heat exchanger, a second cooling tower and a second hydraulic piston pump, wherein a first hydraulic pipeline is fixedly connected between the hydraulic station and the first hydraulic piston pump, a second hydraulic pipeline is fixedly connected between the hydraulic station and the second hydraulic piston pump, and air rings are fixedly arranged at the inner position of the filling machines. According to the novel high-temperature asphalt cold filling system, the first hydraulic piston pump, the hydraulic station, the first heat exchanger, the first cooling tower, the air blowers, the filling machines, the second heat exchanger, the second cooling tower, the second hydraulic piston pump and the air rings are arranged, and the high-temperature liquid asphalt can thus be smoothly and directly filled after being greatly cooled, so that the filling efficiency is guaranteed, and the risk of pipe blockage is avoided.

Description

technical field [0001] The invention relates to the technical field of asphalt cold filling equipment, in particular to a novel high-temperature asphalt cold filling system. Background technique [0002] Asphalt is a viscous object at room temperature, and it becomes a liquid at high temperature. As the temperature decreases, the viscosity of liquid asphalt becomes larger and larger. Usually, when the modified asphalt is around 130°C, the road When asphalt is around 100°C, its fluidity becomes very poor. It is this characteristic that has made asphalt only used at high temperatures (modified asphalt above 130°C and road asphalt above 100°C) for a long time. Filling, storage and transportation in iron barrels or tank trucks. [0003] However, when the modified asphalt is lower than 130°C and the road asphalt is lower than 100°C, the fluidity of the asphalt has become very slow. At this time, the efficiency of filling is not only extremely low, but a little carelessness will ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of high-temperature asphalt cold filling system to solve the problem in the above-mentioned background technology that when the modified asphalt is lower than 130°C and the road asphalt is lower than 100°C, the fluidity of the asphalt becomes very slow. At this time, the efficiency of filling is not only extremely low, but a little carelessness will cause the asphalt to solidify in the conveying pipeline, causing the danger of pipe blockage, which is very unfavorable for asphalt filling, and when the temperature is higher than 130°C, the liquid supply Asphalt packaging containers are very limited, and are usually only suitable for iron drum packaging and filling truck storage and transportation, which greatly consumes energy and increases production costs.
