Control, detection and alarming device for circulating water system for internal mixer

Abstract

The invention relates to a control, detection and alarming device for circulating water system for an internal mixer, which is characterized in that a solenoid electric valve is assembled on a soften water pipe communicated with a circulation loop system of the internal mixer, a temperature detection element and a digital electro connecting pressure gauge are respectively assembled in the circulation loop system of the internal mixer, the switching value signal of the upper pressure limit and the lower pressure limit of the digital electro connecting pressure gauge is accessed into an input interface circuit of a PLC (programmable logic controller), and an output interface circuit of the PLC outputs relevant switch on or switch off control signal for the solenoid electric valve and a combined aural and visual alarm. In the system, when the pressure of circulation water is higher or lower than a rated value, the PLC is used for controlling the on and off of the solenoid electric valve so as to replenish water for the system or cut off the water replenished; and when interval time spent on switching on the solenoid electric valve under the control of the PLC for replenishing water for three times is lower than the rated value, leak point occurs in the system, and the combined aural and visual alarm alarms. The device is prompt and efficient in water replenishment controlling and water leakage detection and alarming, softened water leakage amount is reduced, and sizing material quality is improved.

Description

technical field [0001] The invention relates to heating or cooling parts of mixing or kneading equipment, especially a control, detection and alarm device for the circulating water system of an internal mixer. Background technique [0002] As we know, in order to ensure the stability of the rubber material produced in the internal mixer, demineralized water is connected to the mixing chamber, rotor and upper and lower top bolt circulation circuits, and these parts are cooled or heated according to the process requirements to ensure The glue works in a relatively stable closed space. However, during the production process, the alloy layer on the surface of the above-mentioned parts will be severely worn due to long-term friction with the rubber material, and it is easy to generate leakage points in the circulation loop. Large leaks can be found by the operator, but relatively small leaks are not easy to detect. The softened water will be replenished all the time, and the lea...

Problems solved by technology

However, during the production process, the alloy layer on the surface of the above-mentioned parts will be severely worn due to long-term friction with the rubber material, and it is easy to generate leakage points in the circulation loop.

Large leaks can be found by the operator, but relatively small leaks are not easy to detect. The softened water will be replenished all the time, and the leaked softened water will be mixed into the rubber compound, which not only wastes water resources, but also has a great impact on the performance of the rubber compound.
