System for replacing ceramic roll on line

Abstract

A system for replacing a ceramic roll on line comprises a cooling device and a roll replacement device, wherein the cooling device is suitable for being nested on a ceramic roll bonding part required to pass through the inside of a box body of a slag box when ceramic roll is replaced; the cooling device comprises a main cooling body surrounding the outside of the bonding part and a gas feeding device for providing cooling gas, and a gap which is 0.1-0.5 mm wide is formed between the main cooling body and the bonding part; a cooling channel communicated with the gap is formed in the main cooling body, the gas feeding device inputs the cooling gas to the gap through the cooling channel, and the gas feeding speed and pressure of the cooling channel providing gas for the gap are higher than the exhaust speed of the gap and the pressure of the slag box respectively; the roll replacement device is used for pulling the ceramic roll out of the slag box. The system solves the technical problem that a ceramic roll in the prior art is not suitable for online replacement, has a better ceramic roll cooling effect and is more suitable for online replacement of the ceramic roll.

Description

technical field [0001] The invention relates to the field of glass manufacturing. Specifically, a system for replacing ceramic rollers on-line. Background technique [0002] The transition roller table equipment is one of the key equipment on the float glass production line. The roller is the most important part of the transition roller table equipment. When the roller is running, the glass is drawn out of the tin bath, and the drawn glass ribbon is sent to Enter the annealing kiln for annealing. [0003] In order to ensure the quality of the glass, the transition roller generally uses a ceramic roller, but the ceramic roller is limited by its own material structure, and metal roller heads must be installed at both ends to meet the transmission requirements. The ceramic and metal materials are connected by bonding. This kind of glue can only maintain stable performance within 150°C. The working surface of the transition roller is set inside the slag box, and the two ends a...

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that in the prior art, the cemented part of the ceramic roller and the metal shaft head is cooled by heat exchange, the cooling effect is not good, and it is not suitable for on-line replacement of ceramic rollers. A system suitable for on-line replacement of ceramic rollers with better roller cooling
