Casting asphalt mixture vertical stirrer

Abstract

The invention relates to a casting asphalt mixture vertical stirrer. The stirrer comprises a frame, a motor, a first deceleration mechanism, a second deceleration mechanism, a stirring shaft, a stirring blade, a guiding screw, a guiding nut, and a stirring pot, wherein the second deceleration mechanism mainly comprises a second deceleration box body, a main transmission gear, at least two driven gears, a second input shaft, and a second output shaft; the main transmission gear is fixedly connected to the second input shaft; the input shaft is connected to an input shaft of the first deceleration mechanism; the two driven gears are uniformly distributed in the circumferential direction of the main transmission gear and are engaged with the main transmission gear; the driven gears are fixedly connected to the corresponding second output shaft; the second output shaft is hinged with the second deceleration box body; the second deceleration box body is hinged with the second input shaft; when the main transmission gear is engaged and rotates with the driven gears, the driven gears rotate around the second output shaft, and simultaneously revolves around a driving wheel of the second input shaft. The invention has the advantages of uniform stirring, no dead angle, large stirring pot capacity, and good sealing.

Description

technical field [0001] The invention relates to asphalt processing equipment, in particular to a castable asphalt mixture vertical mixer. Background technique [0002] At present, epoxy asphalt concrete is still the main pavement for domestic steel bridge decks. Epoxy asphalt concrete has been widely recognized for its excellent quality after the actual traffic inspection. However, castable asphalt mixture is recognized and widely used in developed countries for its high temperature resistance, anti-aging, natural fluidity at high temperature, and high viscosity. [0003] At present, epoxy asphalt concrete is the main pavement for domestic steel bridge decks. Epoxy asphalt concrete is rarely used due to factors such as high cost and difficulty in construction control. The pourable asphalt mixture is made of modified asphalt and pure natural asphalt from the bottom of Trinidad Lake in the United States. It has high stirring temperature, high viscosity, and large fluidity. It...

Problems solved by technology

Because, during actual stirring, the blade 5 is subject to a large stirring resistance moment, which makes the spring 4 deform toward the center of the small moment, causing the stirring blade to tilt to the center of the stirring pot for stirring, and other places cannot be stirred, resulting in uneven stirring; and Stirring blade 5 is easily deformed and damaged by the strong viscosity resistance of castable asphalt mixture, thus affecting normal stirring

In addition, the distribution of the blades makes the mixing range of the blades not large, which limits the capacity of the mixing pot
