Transmission control mechanism of stirring system

Abstract

The invention relates to the field of glass production machinery, in particular to a transmission control mechanism of a stirring system. The transmission control mechanism is characterized in that: the signal input end of a programmable logic controller (PLC) controlled by a computer is connected with the signal input end of a variable frequency speed regulator set, the signal input end of the variable frequency speed regulator set is connected with the signal input end of a motor, the signal output end of the motor is connected with the signal input end of a clutch, the signal output end of the clutch is connected with the signal input end of a trigger, the signal output end of the trigger is connected with the signal input end of a proximity sensor, and the signal output end of the proximity sensor is connected with the other signal input end of the PLC. The transmission control mechanism has the advantages that: 1, the proximity sensor is matched with the trigger rather than a cheaper coder to monitor the rotational speed and the steering of a stirring blade in real time; 2, the trigger is arranged in the same plane as the stirring blade to simply monitor the phase angle of the stirring blade; and 3, by adopting the PLC for measurement, display and control operation, the transmission control mechanism has high reliability and strong adaptability.

Description

[technical field] [0001] The invention relates to a phase angle control system of each stirring blade in a vertical stirring system of high-temperature molten glass used in a float glass production line, belonging to the field of glass production machinery. Specifically, it is a transmission control mechanism of a stirring system. [Background technique] [0002] In order to reduce the impact on the output and quality of glass products caused by the chemical inhomogeneity and thermal inhomogeneity of the glass liquid, a glass liquid vertical stirrer is installed at the neck of the melting furnace, and the natural uniformity is eliminated or reduced by the mechanical stirring of the stirring blades. Eliminate insurmountable defects, ensure the thermal uniformity and chemical uniformity of the molten glass entering the forming area, and thus produce float glass with excellent optical properties and surface quality. Studies have shown that the rotation speed, rotation direction...

AI Technical Summary

Problems solved by technology

Studies have shown that the rotation speed, rotation direction and phase angle of the stirring blades of each vertical stirrer (especially the rotation speed, steering and phase angle of adjacent stirring blades) are the main factors affecting the stirring effect, but the control of the phase angle of the stirring blades is still limited. There is no good solution, which leads to the inability of various manufacturers to better control and optimize the mixing effect of the vertical mixer for different production processes
