Automatic temperature control dual-horizontal shaft asphalt mixture mixing machine for laboratory

Abstract

The invention relates to an automatic temperature control dual-horizontal shaft asphalt mixture mixing machine for a laboratory. The automatic temperature control dual-horizontal shaft asphalt mixture mixing machine comprises a heat-insulating heating device, a discharging device and a mixing cylinder fixedly provided with a motor at the outer side, wherein a speed reducer is fixedly arranged on an output shaft of the motor, a driving gear is fixedly arranged on the speed reducer, and connected with a first driven gear by virtue of a belt, the first driven gear is fixed at one end of a first mixing shaft positioned in the mixing cylinder, and a second synchronization gear is fixedly arranged at the other end of the first mixing shaft. The first mixing shaft and a second mixing shaft are arranged in the mixing cylinder, so that the working efficiency is remarkably improved and the mixing time is shortened in comparison with the original mixing machine with an single mixing shaft; meanwhile, mixing equipment for a practical engineering can be simulated, so that an experiment result has strong practicability and reliability. Meanwhile, the speed reducer is provided, so that the rotating speeds of the first mixing shaft and the second mixing shaft are conveniently regulated.

Description

technical field [0001] The invention relates to a mixer for a laboratory, in particular to an automatic temperature-controlled double-shaft asphalt mixture mixer for a laboratory. Background technique [0002] At present, the equipment used in the asphalt mixture mixing test in the laboratory is a single-shaft mixer, although the single-shaft mixer has the advantages of simple structure, convenient operation and low cost. However, its stirring efficiency is low, it takes a long time to mix the mixture evenly, and the equipment is too heavy. Experimental research shows that: too long mixing time will cause aging and hardening of asphalt, decrease of penetration and ductility, increase of softening point, and decrease of fatigue resistance of asphalt mixture. As a result, the performance of the mixture changes, which affects the accuracy of the subsequent road performance test of the mixture. Contents of the invention [0003] The purpose of the present invention is to ove...

However, its stirring efficiency is low, it takes a long time to mix the mixture evenly, and the equipment is too heavy

Experimental research shows that: too long mixing time will cause asphalt to age and harden, the penetration and ductility will decrease, the softening point will increase, and the fatigue resistance of asphalt mixture will decrease.

The performance of the mixture will change, which will affect the accuracy of the subsequent road performance test of the mixture.
