Emulsified modified asphalt experimental machine

Abstract

The invention discloses an emulsified modified asphalt experimental machine, which belongs to the field of asphalt equipment. The emulsified modified asphalt experimental machine consists of an asphalt tank, an asphalt measuring and transporting device, a soap liquid tank, a soap liquid measuring and transporting device, a colloid mill, an asphalt cooling system and a PLC (Programmable Logic Controller) control system. When in work, asphalt and soap liquid are respectively added into the asphalt tank and the soap liquid tank, the asphalt and the soap liquid are heated to a needed technological temperature by utilizing an automatic temperature control system, the asphalt measuring and transporting device and the soap liquid measuring and transporting device are switched on to extract a corresponding medium, the medium is injected into the colloid mill according to a ratio, the asphalt is emulsified by virtue of shearing and grinding of the colloid mill, and under the action of a back pressure system, the finished product emulsified asphalt is obtained by virtue of heat exchange of a heat exchanger. The temperature, pressure and valve switching at various positions in the whole process as well as the starting and stopping of each system are all controlled by the PLC, so that the operating efficiency is increased.

Description

Technical field [0001] The invention relates to the field of asphalt equipment, in particular to an emulsified modified asphalt test machine. Background technique [0002] At present, the emulsified asphalt produced by the mass production equipment of factory-based emulsified modified asphalt may have problems such as poor product quality and unstable product indicators. The main causes of the problems are unqualified raw material indicators, unreasonable production processes, and defective process equipment Therefore, the mass production of emulsified modified asphalt without small-scale laboratory production has great risks and waste. [0003] If the emulsified modified asphalt experimental equipment is used for small-scale trial production before mass production, it will have a positive guiding significance for determining and optimizing the batch production ratio, process parameters, etc.; at the same time, the use of small-scale trial production can be used to study high perfo...
