Energy consumption-related quasi-cosine curve type temperature control method and device for rubber internal mixer

Abstract

The invention provides an energy consumption related quasi cosine curve type temperature control method and a device of a rubber internal mixer, and a constant-temperature control method which is adopted in a material mixing process by a traditional rubber internal mixer is changed. Consumed electric energy input into a driving motor of the rubber internal mixer in the material mixing process is measured and is changed into a numerical signal which represents the consumed electric energy so as to be transferred to a temperature control system as a temperature control parameter to participate in temperature control, and additionally, according to a specific material mixing temperature control process of the internal mixer, different mixing cycle and time sequence mathematical model parameter equivalent controllers are set, so that temperature control nodes and time sequences at different moments in the mixing process are determined, an energy consumption related type variable-temperature curve method in the material mixing process of the internal mixer is mastered so as to perform intelligent optimal design on the temperature control device in the material mixing process of the internal mixer, electric energy and cooling water are saved, the unit energy consumption for mixing materials is reduced, and the purposes of saving energy and reducing consumption in timely temperature adjustment are achieved.

Description

technical field [0001] The invention relates to the field of rubber processing machinery, in particular to a quasi-cosine curve type temperature control method and device related to energy consumption (electric energy) of a rubber internal mixer during the material mixing process. Background technique [0002] Rubber internal mixer is one of the most basic and key equipment in rubber industry enterprises. It not only consumes a lot of power, but also consumes a lot of cooling water, and has high requirements for temperature control. In order to mix the high-performance rubber compound and achieve the ideal temperature control effect, it not only improves the material mixing efficiency of the internal mixer, but also prevents the material in the internal mixer from being too high in temperature during the mixing process to cause glue burning. People have been doing research in this area for many years. [0003] The traditional temperature control method of the rubber intern...

[0005] In view of the above characteristics, the traditional internal mixer temperature control method, because the temperature control of each section is based on the comparison between the circulating return water temperature and its set temperature value to achieve constant temperature temperature adjustment, input electric energy-mechanical energy-thermal energy from the internal mixer ( Make the temperature of the mixed rubber material rise)--the rubber material is transferred to the circulating water through heat mass; when the temperature sensor 8-1 (8-2, 8-3) installed on the circulating water return pipeline detects that the temperature of the circulating water is higher than When setting the temperature, the temperature regulator outputs a cooling control signal to open the cooling valve 1-1 (1-2, 1-3), so that the temperature of the circulating water drops, and then the temperature of the rubber material drops through the transfer of heat and mass. It can be seen that Such a temperature adjustment method, due to the heat transfer causality and timing relationship, will inevitably produce a serious temperature adjustment lag, making the temperature control untimely
