Abstract

The invention discloses asphalt concrete plant-mix hot recycling equipment with an improved structure. The equipment comprises an old asphalt mixture treatment system, a new aggregate treatment system, a new asphalt material treatment system, an additive treatment system and a stirring device, and is characterized in that: the old asphalt mixture treatment system comprises an old hot reclaimed asphalt storing and metering device for storing and metering old hot reclaimed asphalt, and the device is arranged above the stirring device and is arranged in the way of directly putting the old hot reclaimed asphalt into the stirring device below the device; the new aggregate treatment system comprises a new aggregate storing and metering device and a new aggregate conveying device; the new aggregate storing and metering device is used for storing dried, heated and sieved new aggregate and metering the new aggregate; and the new aggregate conveying device is connected with the new aggregate storing and metering device and the stirring device and is used for conveying the new aggregate to the stirring device. By using the structure, the problem of material sticking brought by conveying the old hot reclaimed asphalt can be solved, and the failure rate of the equipment can be reduced.

Description

technical field [0001] The invention relates to an asphalt concrete plant mixing heat regeneration equipment with improved structure. technical background [0002] It is known that the asphalt concrete pavement will be aged and damaged after being used for a period of time, and needs to be refurbished. A lot of waste material - old asphalt concrete - is generated during the renovation. From the perspective of environmental protection and circular economy, it is necessary to recycle these old asphalt concrete. The factory mixing hot recycling method is to transport the excavated old asphalt concrete back to the mixing plant, and then concentrate on crushing, and according to the quality requirements of the road construction, carry out the ratio design, determine the addition ratio of the old asphalt mixture, and then mix the old asphalt Raw materials and regeneration agent, new asphalt materials, new aggregates, etc. are remixed in a mixer in a certain proportion to form a ...
