Heat insulation recycling transport vehicle for hot air circulation asphalt mixture

Abstract

A heat insulation recycling transport vehicle for hot air circulation asphalt mixture comprises a vehicle chassis, an asphalt mixture bin, a bin lifting mechanism, an excess material recycling transport mechanism, a follow charging hopper and an electric control device. The asphalt mixture bin is a tipper-hopper discharge type hot air circulation heating heat insulation bin mechanism, the heat insulation bin mechanism comprises a flipping frame, a heat insulation bin, a hot air circulation furnace device and a generator set, a feeding hopper is arranged on the heat insulation bin and is in butt joint with the follow charging hopper, the heat insulation bin comprises a heat insulation box, a bottom hot air channel, a tail hot air channel, two side wall hot air channels, two groups of spoilers and an inner bin, and the hot air circulation furnace device comprises a diesel tank, a diesel supply device, a hot air furnace and a high-temperature circulation fan. The heat insulation recycling transport vehicle has the advantages that heating is quick and uniform, the heat efficiency is high, hot air with waste heat can be recycled, loading transport heat insulation effects are fine, and the best laying temperature and quality of the asphalt mixture are constantly ensured.

Description

technical field [0001] The invention belongs to the technical field of heat preservation of asphalt mixture, in particular to a hot air circulation type asphalt mixture heat preservation recovery transport vehicle. Background technique: [0002] During the overhaul of the asphalt pavement, it is necessary to carry out long-distance and large-scale transportation of the asphalt mixture mixed in the mixing plant and long-term insulation work during the construction process. Through specialized maintenance machinery (such as asphalt pavement thermal recycling machine) to realize the repair and maintenance of asphalt pavement diseases. During the construction process, the temperature of the asphalt mixture is kept within a certain range, which plays a vital role in the maintenance quality of the pavement. If the temperature of the asphalt mixture is too low, it will have a significant impact on the compactness of the pavement. [0003] At present, there are several kinds of as...
