Small analog machine for mobile guss-asphalt heating and mixing laboratory

Abstract

The invention discloses a small analog machine for a mobile guss-asphalt heating and mixing laboratory. The small analog machine comprises a machine body, wherein wheels are arranged at the bottom of the machine body, and a stirring shaft seat is arranged on the machine body; a stirring shaft is mounted on the stirring shaft seat through a bearing, a stirring crock is arranged on the stirring shaft through a bearing, and a stirring blade is arranged on the stirring shaft in the stirring crock; a motor is arranged on the machine body, and an output shaft of the motor is connected with the stirring shaft through a speed changer; an opening is formed in the stirring crock, and a cover is arranged on the opening; a ceramic plate heating module is arranged on the outer wall of the stirring crock, and a thermal insulating layer covers the external part of the ceramic plate heating module; through holes are formed in the stirring shaft seat, an upper insertion hole and a lower insertion hole, corresponding to the through holes are respectively formed in the upper part and the lower part of one end of the stirring crock; the through holes can be respectively connected with the upper insertion hole and the lower insertion hole through bolts; a control cabinet is arranged on the right side of the machine body; a temperature sensor is arranged in the stirring crock, and the ceramic plate heating module and the temperature sensor are electrically connected with the control cabinet respectively. The small analog machine meets test results of laboratory tests for detecting various performances of mixed asphalt and producing few mixtures, is also suitable for large Cooker machines, saves resources, and is accurate in test data.

Description

technical field [0001] The invention relates to equipment for MA asphalt concrete construction, in particular to a small simulator for pouring asphalt mobile heating mixer truck (Cooker) laboratory. Background technique [0002] In the production process of the MA mixture, it is required to put the MA mixture into the Cooker machine for secondary mixing and heating. In the laboratory test, in order to test the fluidity, hardness and dynamic stability of MA asphalt mixture, it is inevitable to go through the process of Cooker machine secondary mixing and heating conditions. If the experiment is carried out on conventional Cooker equipment, too much material needs to be produced at a time to meet the Cooker working conditions (the Cooker has a large capacity, generally up to 8 tons, 10 tons, and 13 tons), which wastes resources and increases the cost of the experiment; If the material produced at one time is too little, it will not meet the working conditions of the cooker ma...

AI Technical Summary

Problems solved by technology

If the experiment is carried out on conventional Cooker equipment, too much material needs to be produced at a time to meet the Cooker working conditions (the Cooker has a large capacity, generally up to 8 tons, 10 tons, and 13 tons), which wastes resources and increases the cost of the experiment; If the material produced at one time is too little, it will not meet the working conditions of the cooker machine, and the interference of uncertain factors in large-scale cooker equipment cannot be ruled out. Moreover, the conventional cooker machine uses gas for heating, so it is difficult to control the heating temperature of the mixing tank , has an impact on the accuracy of the experimental data, and even draws wrong conclusions
