Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail, the present invention is used for controlling the rotation speed and the phase angle of stirring blade, and its working environment is the kiln neck place (10) of float process, see image 3 . Initially, the six stirring blades (9) are staggered at 90° and arranged at the kiln neck (10). During operation, the adjacent stirring blades (9) turn in opposite directions, and the phase difference remains unchanged to ensure that the glass liquid entering the forming area All can be homogenized by stirring with a mixer. Such as figure 1 , 2 As shown: the proximity sensor (1) is installed on the bracket (8), the trigger (2) is fixed on the clutch (7), the motor (4) with the frequency conversion speed controller (5) is directly connected to the reducer (6) and The clutch (7) drives the stirring blade (9) to rotate once, and the proximity sensor (1) can receive a signal sent b...

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...
