Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass etching, in particular to a device for uniform bubbling in glass etching. BACKGROUND

[0002] The bubbling device in the glass etching tank produces fine bubbles, which impact and remove the powder generated on the glass surface, so that the speed of powder falling off in different parts is uniform, thereby ensuring the flatness of the glass surface.

[0003] The bubbling device of the prior art generally has a small hole on the air pipe to generate small bubbles. In order to reduce the blockage of the small hole, various structures have been proposed in the prior art. For example, a bubbling device for glass etching and thinning is disclosed in Chinese Utility Model Patent No. ZL202121078395.9, which sets a downwardly inclined air outlet hole. A bubbling device for glass etching is disclosed in Chinese Invention Patent No. ZL201810832346.6, which sets an upwardly inclined air outlet hole. Some have a spraying device. A bubbling device for a glass etching machine is disclosed in Chinese Utility Model Patent No. ZL201721375971.X, which sets a rotatable air outlet hole.

[0004] The above structures have good effects on avoiding blockage of the air outlet hole, but still have deficiencies. For example, the above structures lack a vibration function, which causes the air outlet pipe to easily hold glass powder. After a long period of work, special cleaning is required. Since the air outlet hole is continuously emitting air, the size of the generated bubbles is related to the diameter of the air outlet hole, resulting in a relatively single size of the generated bubbles, which cannot further generate smaller bubbles and has a greater impact on thin glass. SUMMARY

[0005] To solve the above technical problems, the present application provides a device for uniform bubbling in glass etching, which can vibrate the air outlet pipe to shake off the attached glass powder, generate smaller bubbles of different sizes, reduce the impact on thin glass, and has good practicality.

[0006] This invention discloses an apparatus for uniform bubbling during glass etching, comprising an etching tank, an air supply pipe, and an oil-water separator. The oil-water separator is installed at the input end of the air supply pipe, which extends into the bottom of the etching tank. The apparatus also includes multiple air outlet pipes, multiple air nozzles, multiple supports, and an air outlet regulating structure. The multiple air outlet pipes are elastically mounted at the bottom of the etching tank via multiple supports. The input ends of the multiple air outlet pipes are connected to the output ends of the air supply pipe. The multiple air outlet pipes are arranged parallel to each other and staggered vertically. Multiple air nozzles are obliquely arranged on the side walls of each air outlet pipe, with each nozzle facing an adjacent air outlet pipe. Each of the multiple air outlet pipes is equipped with an air outlet regulating structure. Under the action of airflow, the air outlet regulating structure vibrates the multiple air outlet pipes and intermittently blocks the air outlets. The air nozzles decongest the air flow, creating finer and more varied bubbles. The oil-water separator filters and separates the oil and water from the compressed air entering the air supply pipe. The air is then fed into multiple outlet pipes and ejected through multiple nozzles, generating bubbles. These bubbles propagate towards adjacent outlet pipes, creating turbulence and impacts that reduce glass powder buildup. The outlet pipes vibrate under the influence of the air flow regulating structure, dislodging the glass powder and reducing the need for specialized cleaning. Simultaneously, the air flow regulating structure adjusts the airflow rhythm of the nozzles, resulting in discontinuous airflow and finer, more varied bubbles, further reducing impact on thin glass and enhancing practicality.
