A bubbling device for glass etching

Abstract

The invention proposes a glass etching bubbling device, comprising: a bubbling tube, the bubbling tube includes an air supply pipe and a horizontal pipe, and the air supply pipe and the horizontal pipe are connected through an air supply three-way pipe fitting; a spraying device, the spraying The device includes a circulation pump providing liquid circulation power and a plurality of spray pipes arranged in parallel, and the circulation pump and the spray pipes are connected through a spray tee pipe; a rectification plate with a plurality of bubbling holes, the The rectifying plate is used to shield the spraying liquid flow generated by the spraying device, and allow the generated air bubbles to enter the top of the rectifying plate evenly from the bottom of the rectifying plate, and at the same time prevent the powder produced by etching from falling and blocking the horizontal tube hole. The invention can greatly improve the production quality , Extend the maintenance cycle and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of glass production equipment, in particular to a bubbling device. Background technique [0002] In the process of liquid crystal glass production, the glass plate needs to be thinned. At present, the most common method is to immerse the glass in an acid bath filled with hydrofluoric acid to etch the glass. During the glass etching process, the glass surface will produce Powder, different parts of the powder naturally fall off at different speeds, which will cause the surface of the glass to become rough after etching. [0003] In the prior art, in order to solve the problem of powder adhesion, a bubbling device is generally added to remove the powder on the glass surface through the bubbles generated at the bottom of the etching tank. However, the use of air bubbles will still cause some problems, such as the bubbles will gather during the process of rising from the bottom, and the bubbles gathered in the ...

AI Technical Summary

Problems solved by technology

However, the use of air bubbles will still cause some problems, such as the bubbles will gather during the process of rising from the bottom, and the bubbles gathered in the local area will generate eddy currents, and the eddy currents will cause the pressure difference in the local area to increase. For liquid crystal glass with a thickness of less than 1mm In other words, eddy currents and excessive pressure differences in local areas will cause glass damage, affect production efficiency, and reduce production quality

The falling powder will block the bubbling device and affect the bubbling effect. In order to ensure the normal production, the company will regularly clean and dredge the bubbling device, which takes time and effort and brings great inconvenience to production.
