Performance test system of vertical type mechanical agitation equipment

Abstract

The invention discloses a performance test system of vertical type mechanical agitation equipment. A spiral semicircular tube clamping sleeve is welded on the outer side of the agitation equipment; steam heating, heat conducting oil heating and cooling water cooling are realized by controlling a valve in a pipeline; a flow meter, a temperature meter and a pressure meter are arranged on an upper port and a lower port of the clamping sleeve; two driving systems are arranged at the upper end of the agitation equipment, so that dual-shaft agitation (having three motion modes, namely homodromous rotation, reverse rotation and single-shaft rotation) as well as frequency conversion and speed regulation are realized; torque sensors are arranged on agitation shafts at the output ends of two motors; a thermal resistance sensor is arranged on the surface of the inner wall of the agitation equipment; a thermocouple sensor is arranged in internal liquid; and the sensors are connected with a console. The performance test system can perform cold and hot die tests on low-viscosity fluid, middle-high-viscosity fluid, Newton fluid and non-Newton fluid under different operating parameters so as to obtain parameters such as a heat conducting coefficient, a mixing time, agitation power and the like, and evaluate the heat conducting performance, the mixing characteristic and the power consumption characteristic of various working conditions.

Description

technical field [0001] The invention relates to a performance test system of a mechanical stirring device, in particular to a performance test system of a vertical mechanical stirring device. Background technique [0002] Mechanical stirring equipment can be used for single-phase mixing or multi-phase mixing of materials. It can be operated intermittently or continuously. It has the characteristics of good mixing effect, large phase contact area, high heat transfer and mass transfer efficiency, and is widely used. In the chemical process industry, it is suitable for the mixing process of various physical properties (low viscosity and medium-high viscosity, Newtonian fluid and non-Newtonian fluid) and various operating conditions (temperature, pressure), used in synthetic plastics, synthetic fibers, synthetic rubber, medicine , Pesticides, fertilizers, coatings, food, metallurgy, wastewater treatment and other industries. However, the requirements for mechanical stirring equ...

Problems solved by technology

However, the general stirring test bench can only carry out a single experiment. If a certain operating condition changes, the experimental test cannot be carried out. This requires the construction of a wide controllable range of operating conditions (such as concentration, temperature, residence time, pressure, etc.). , a mixing equipment test bench that can adapt to a wide range of physical properties and can conduct experiments on various working conditions
