Referring to fig. 1, the embodiment discloses a flow channel temperature control system 3 based on card-issuing water drum control, which comprises a flow channel temperature feedback mechanism 1, a card-issuing water drum device 2 and a control system 3.
The fluid channel temperature feedback mechanism 1 is arranged at the fluid channel and used for detecting the temperature of the fluid channel; the key loop of temperature control is a real-time temperature detection feedback mechanism, and the temperature control cannot realize closed loop without accurate temperature detection feedback. The flow channel is the outlet of the end of the melting section and is also the inlet of the tin bath section, and production staff can observe whether the quality of the glass liquid can reach the condition of producing ultrathin glass. The temperature of the fluid channel is generally controlled within 1100-1150 ℃, and the fluid channel thermocouple of the control system 3 is an S-shaped platinum-rhodium 10-platinum thermocouple. The S-type platinum-rhodium 10-platinum thermocouple has the advantages of highest accuracy, best stability, wide temperature measurement temperature area, long service life and the like, has good physical and chemical properties, good thermoelectric stability and oxidation resistance at high temperature, and is suitable for oxidizing and inert gases.

The driving chain wheel 23 is wound on a driving shaft 26 and a driven shaft 27, the driving shaft 26 and the driven shaft 27 are arranged on the frame 21 in parallel, so that the driving chain wheel 23 is horizontally elongated in an O shape, and the driving shaft 26 is connected with a transmission shaft of the motor 22; the upper end chain of the driving sprocket 23 is located on the slide rail and fixedly connected with the sliding mounting portion 241, specifically, when the chain of the driving sprocket 23 passes through the sliding mounting portion 241, the corresponding chain is removed, and then the sliding mounting portion 241 is connected to the missing chain, so that the support member 24 is fixedly connected with the driving sprocket 23.
Wherein a plurality of support members 24 can be provided for ensuring a reliable connection of the water drum 25, in this embodiment two support members 24 are provided for clamping the water drum 25.
When the water drum 25 is required to extend into the cooling part, the motor 22 is controlled to start, the driving shaft 26 of the motor 22 drives the driving shaft 26 to rotate, and the driving shaft 26 drives the driving sprocket 23 to rotate, so that the driving sprocket 23 slides on the sliding rail, thereby driving the supporting piece 24 to move towards the direction of the cooling part, and further driving the water drum 25 below the supporting piece 24 to extend into the cooling part.
