Abstract

The embodiment of the invention discloses a multistage segmental malaxation cold adding recycled asphalt concrete plant mixing device, and relates to the field of building devices. The plant mixing device comprises a frame body, a hot material scale, a cold adding material scale, a primary malaxation cylinder, a hot material storage bin and a secondary malaxation cylinder, and the hot material scale and the cold adding material scale are arranged on the upper part of the frame body; the primary malaxation cylinder is arranged below the hot material scale and the cold adding material scale; thematerial inlet of the primary malaxation cylinder is connected with the material outlet of the hot material scale and the material outlet of the cold adding material scale; and the material inlet ofthe hot material storage bin is connected with the material outlet of the primary malaxation cylinder, and the material outlet of the hot material storage bin is connected with the material inlet of the secondary malaxation cylinder. The number of the malaxation cylinders is increased, new asphalt concrete is mixed with old asphalt concrete more evenly, the heat released by the new asphalt concrete is used for making the old asphalt concrete be fully melted, and the quality of finished products is improved. The asphalt concrete plant mixing device has the advantages that the structure is simple, the production cost is low, energy consumption is low, mix ratio of old materials is furthest ensured, and the product quality is high.

Description

technical field [0001] The embodiment of the present invention relates to the field of construction equipment, in particular to a multi-stage segmental mixing cold-added recycled asphalt concrete factory mixing equipment and method. Background technique [0002] The existing cold-adding old asphalt concrete technology can only add 15% of the old asphalt concrete, and more than 15% must be hot-added, and hot-adding needs to add a series of equipment such as regeneration rollers, which increases production costs; due to the heating of hot-adding The method is direct combustion heating, which has large heat loss, high energy consumption and is easy to cause asphalt aging, changing the original asphalt concrete mix ratio, so that the quality of the product cannot be guaranteed. Contents of the invention [0003] For this reason, the embodiment of the present invention provides a multi-stage segmental mixing cold-added recycled asphalt concrete plant mixing equipment and method...
