Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of float glass production, and in particular to a tin ash cleaning device. BACKGROUND

[0002] In the production process of ultra-thin electronic float glass, a slag box is connected to the outlet of a tin bath. In order to prevent scratches on the lower surface of the glass sheet, sulfur dioxide is usually passed through the lower part of the slag box to form a sulfur dioxide film on the lower surface of the glass to reduce scratches. Since the slag box is also connected to an annealing furnace, oxygen in the annealing furnace will enter the outlet of the tin bath. The triangular area of the lip of the tin bath is contaminated by sulfur and oxygen, forming tin oxide or stannous oxide, which gradually accumulates in the triangular area of the outlet of the tin bath. Long-term accumulation can easily cause tin sticking and form imprints, which will scratch the lower surface of the glass and seriously affect the production quality of the glass.

[0003] At present, when cleaning the contaminants in the triangular area of the lip of the tin bath, the conventional method is to use a steel belt to extend into the lip brick or the lower surface of the glass sheet to carry out tin ash. However, the above method has the following disadvantages: it affects the normal production of the glass, affects the production progress, and tin ash is easily carried from the glass sheet to the transition roller, causing secondary pollution, incomplete cleaning, and low cleaning efficiency. In addition, the steel belt is hard and can easily cause broken glass, resulting in production accidents and affecting the yield. Therefore, the present application provides a tin ash cleaning device. CONTENT OF THE PRESENT INVENTION
