Therefore, the service life of the whole fused salt is effectively prolonged, when the fused salt in the whole furnace body needs to be cleaned or replaced, only the cover of the discharging opening needs to be opened, the fused salt is discharged from the discharging opening, and convenience and rapidness are achieved.

Description

Technical Field

[0001] This application relates to the technical field of glass strengthening, and particularly to a chemical strengthening furnace. Background Art

[0002] During the process of chemically strengthening glass, especially in the application process at the back end of ultra-thin electronic glass substrates, in order to improve the strength of the glass, it is usually necessary to chemically strengthen the ultra-wave glass substrate. Existing strengthening usually uses a strengthening furnace to heat the strengthening salt until it melts, and then the cleaned ultra-thin glass is lifted into the molten strengthening salt through a rack, so that the glass undergoes ion exchange in the strengthening salt to achieve chemical strengthening of the ultra-thin glass plate. However, during the strengthening process, it is inevitable to introduce impurities into the strengthening salt. Since the impurities cannot be effectively cleaned, the service life of the strengthening salt is short, and the impurities will accumulate continuously, eventually resulting in the need to replace the molten salt. The existing strengthening furnace is not convenient for replacing the strengthening salt. Utility Model Content

[0025] For ease of description, spatial relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position inversion, attitude change, or change in motion state, then these directional indications will change accordingly.
