A cold recycling mixing tank for emulsified asphalt

Abstract

The invention relates to the field of pavement construction equipment, and particularly relates to an emulsified asphalt in-plant cold recycling mixing cylinder which comprises a mixing cylinder and a pair of stirring shafts, wherein the mixing cylinder is in a box-shaped structure of which the upper end is open; the opening of the mixing cylinder is provided with a plurality of water supply pipes and asphalt pipes; the water supply pipes and the asphalt pipes are horizontally arranged at the opening of the mixing cylinder in a staggered manner; the stirring shafts are arranged in the mixing cylinder in parallel; each of the stirring shafts is provided with a plurality of serrated stirring blades; the stirring blades on each stirring shaft comprise long-diameter stirring blades and short-diameter stirring blades; the long-diameter stirring blades and the short-diameter stirring blades are distributed at equal intervals on the stirring shafts in a staggered manner; and the long-diameter stirring blades and the short-diameter stirring blades on a first stirring shaft are respectively arranged corresponding to the short-diameter stirring blades and the long-diameter stirring blades on a second stirring shaft. Thus, the emulsified asphalt in-plant cold recycling mixing cylinder provided by the invention is high in stirring efficiency, realizes uniform and sufficient mixing of a mixture and simultaneously reduces waste of raw materials.

Description

technical field [0001] The invention relates to the field of road surface construction equipment, in particular to an emulsified asphalt plant mixed cold recycling mixing tank. Background technique [0002] The asphalt mixed cold recycling process is a new pavement engineering process that is being gradually promoted at present. It can not only save a lot of energy and resources, but also has significant economic benefits, and is conducive to environmental protection. Most of the existing emulsified asphalt plant mixed cold regeneration mixing tanks are single-shaft mixing, the mixing efficiency is low, and the mixing is insufficient. When the mixing speed is fast and there is a lot of mixture in the mixing tank, the mixture is easy to overflow from the mixing tank, causing Raw material wastage. Contents of the invention [0003] Aiming at the above technical problems, the present invention designs and develops an emulsified asphalt plant cold recycling mixing cylinder, t...
