Environment-friendly asphalt concrete mixing equipment

Abstract

The invention relates to environment-friendly asphalt concrete mixing equipment, which includes drying that inn cylinder, stirring drum, the drying inner cylinder and the stirring outer cylinder are connected with each other through a rotatable sealing structure, A drying inn barrel is rotatably movable relative to that stirring outer barrel, A material discharge box is arrange at that rear end outside the stirring, The rear end of the drying inner cylinder is fixedly connected with one end of a plurality of supporting rods, the other end of the supporting rods is fixedly connected with the stirring shaft, the central axis of the stirring shaft coincides with the central axis of the stirring outer cylinder, the rear end of the stirring shaft is assembled on the outer wall of the discharging box through bearings, and a plurality of stirring devices are installed on the stirring shaft; The invention combines the drying drum with the forced stirring, which is small in volume, convenient to carry, plays the role of drying and stirring, improves the stirring effect, shortens the process flow and accelerates the construction progress.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete mixing, in particular to an environment-friendly asphalt concrete mixing equipment. Background technique [0002] Asphalt concrete is to mix various specifications of aggregate (sand), binder (asphalt or residual oil) and filler mineral powder in a certain proportion to form an asphalt mixture, which is formed into a concrete block for mixing asphalt The mechanical equipment of the mixture is called asphalt concrete mixing equipment. The asphalt plant mixing heat recycling equipment is the old asphalt mixture planed from the invalid asphalt pavement by using regeneration technology. After screening, heating, storage and metering, it is added according to different proportions. In the agitator of each type of asphalt mixing plant, it is evenly mixed with the raw material of the agitator to produce excellent asphalt mixture. [0003] At present, the commonly used asphalt concrete mixing eq...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used asphalt concrete mixing equipment is a mixing station or a mixing building, which has high manufacturing cost, complex structure, large floor space, and inconvenient disassembly. The regenerative drying mixing drums are all continuous non-forced mixing, and natural blanking is carried out by using a paddle plate Stirring, the mixing effect is worse than that of the forced mixing blade, and the mixing is uneven, which affects the construction quality. However, the front of the current forced mixer needs to be dried and heated by a drying drum, and then fed and stirred by the feeding equipment. There are many equipments and long process routes. , increase energy consumption and affect construction progress
