Embodiment Construction

[0016] Such as figure 1 As shown, the process flow of the cold aggregate batching system of the existing widely used continuous asphalt concrete mixing plant is inside the dotted line box. Aggregate is loaded from the well-graded stockpile area to several "cold aggregate batching bins", and batched through each batching device (assuming that 4 specifications of aggregates are used for batching). The metering method of the batching process Usually, the "volume method" is adopted, that is, the cold aggregates of four specifications are sent to a collection belt conveyor after batching, and then the total weight of several kinds of aggregates flowing per unit time is measured by a "belt electronic scale". The detection is used as the basis for proportion control in the future asphalt metering and mineral powder metering. figure 1 The batching process is: multiple cold aggregate batching bins-continuous measurement of cold aggregate (to measure the total amount of aggregate). De...

Abstract

The present invention relates to a cold aggregate batching treatment method for continuous-stirring equipment of bituminous concrete for highroad surface construction and asphalt parement regeneration engineering, and is characterized by that before the cold aggregate is continuously metered, firstly, said cold aggregate is passed through sieving machine to implement pregradation, then continuously metered by means of metering device then fed into continuous bituminous concrete stirring equipment and its next stoving procedure.

Description

technical field [0001] The invention relates to a cold aggregate batching processing method and device for continuous asphalt concrete mixing equipment used in highway pavement construction and asphalt pavement regeneration engineering, in particular to a cold aggregate pre-grading processing method and device. Background technique [0002] In asphalt pavement construction, there are two types of equipment for processing asphalt mixture, continuous asphalt concrete mixing equipment and batch asphalt concrete mixing equipment. Compared with batch asphalt concrete mixing equipment, continuous type asphalt concrete mixing equipment has high efficiency, large output, low energy consumption and high reliability, and has been widely used in road pavement engineering in advanced countries. Since the 1990s, it has become an irreversible trend for continuous asphalt mixing plants to replace intermittent asphalt mixing plants in foreign highway projects. However, even if the continuo...
