Pressure reducing device for electronic display glass platinum channel stirring tank

Abstract

The invention relates to a pressure reducing device for an electronic display glass platinum channel stirring tank. The pressure reducing device comprises a stirring tank (1), wherein a stirring rod (5) vertically upwards penetrates out of a cover plate (4) at the top of the stirring tank (1), a secondary cover plate (6) is connected onto the cover plate (4), a cover plate hole (6a) is formed in the secondary cover plate (6), and the top end of the stirring rod (5) penetrates out of the cover plate hole (6a); a buffer space (7) is formed between the cover plate (4) and the secondary cover plate (6), a gas suction pipe (10) is arranged on one side of the buffer space (7), and the buffer space (7) is communicated with the outside of the gas suction pipe (10); an isolating disc (8) is arranged in the buffer space (7), and the middle part of the isolating disc (8) penetrates through the stirring rod (5); an annular slope bulge (9) is formed at a gap between the stirring rod (5) and the cover plate (4), and the lower surface of the isolating disc (8) is in spacing fit with the annular slope bulge (9). The pressure reducing device has the advantages as follows: gas space pressure is reduced, tiny bubbles are conveniently discharged, the condensate is prevented from reversely dropping into molten glass, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of glass manufacturing equipment, in particular to a decompression device for an electronic display glass platinum channel stirring barrel. Background technique [0002] In the field of electronic display glass manufacturing, in order to increase the uniformity of the molten glass and discharge the tiny bubbles in the molten glass, a stirring process for the molten glass is specially added before entering the forming process. [0003] In the mixing process, the mixing device is composed of a mixing tank, a stirring rod, a stirring tooth, a cover plate, a cover plate hole, a liquid inlet channel, a liquid outlet channel, a liquid discharge channel, an electric heater, etc. The mixing tank and the stirring rod are arranged vertically. The stirring rod is made of platinum material, rotates at a slow speed (1~15rpm), and has a single-ended fixed structure. The stirring rod is inserted into the mixing tank through the hole...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that tiny air bubbles are not easily discharged in the existing mixing tank, and the condensate is easy to reversely fall into the glass liquid. The pressure in the gas space of the barrel makes it easier to discharge the bubbles in the glass liquid, and ensures that the high-temperature gas will not fall back into the glass liquid after condensation, which improves the product quality
