Method for ensuring stability of convection in tank furnace during replacement of batch feeder

Abstract

The invention discloses a method for ensuring the stability of convection in a tank furnace during replacement of a batch feeder. At least two batch feeders are arranged in the tank furnace. The method comprises the following steps: 1, replacing a to-be-replaced batch feeder, stopping work of the to-be-replaced batch feeder, keeping regular work and stayed opening of a batch feeder which is not replaced during replacement; 2, opening the replaced batch feeder and performing feeding after the to-be-replaced batch feeder is replaced; 3, comparing the batch of the replaced batch feeder with thatof the batch feeder which is not replaced after the batch is stabilized, and the batch difference of each batch feeder is ensured to be within 5Kg; synchronously increasing the batch of all batch feeders, restoring the liquid level in a range of 0.5-1.5mm / 4h; and 4, restoring all batch feeders to normal working batch after the liquid level is restored to a required height. According to the method,unstable convection of the tank furnace caused be great batch adjustment can be reduced by slightly reducing the height of liquid level.

Description

Technical field [0001] The invention belongs to the field of cover plate and substrate glass manufacturing, and relates to a method for replacing a feeder to ensure stable convection in a pool furnace. Background technique [0002] In the manufacture of cover and substrate glass, the charging equipment for the cover and substrate glass tank furnace is commonly used equipment, which is mainly used to continuously put the batch materials into the tank furnace, and the charging equipment is the main equipment for the cover and substrate, which is inevitable. At the same time, the current feeding equipment has a short life and is frequently replaced. However, during the replacement of the current feeding equipment of the pool furnace, a large adjustment of the feeding amount is likely to occur, resulting in unstable convection in the pool furnace and unstable convection in the pool furnace. Affect the instability of stones and bubbles. Summary of the invention [0003] The purpose of...

[0002] In the manufacture of cover plate and substrate glass, the feeding equipment for cover plate and substrate glass pool furnace is commonly used equipment, which is mainly used to continuously input batch materials into the pool furnace, and the feeding equipment is the main equipment for cover plate and base plate, which inevitably occurs Various failures and the current feeding equipment have a short service life and are frequently replaced. During the replacement of the current feeding equipment of the pool furnace, it is easy to have a large adjustment of the feeding amount, resulting in unstable convection in the pool furnace. At the same time, the convection in the pool furnace is unstable. Affects the instability of the state of stones and bubbles
