A method for replacing the feeder to ensure the stability of convection in the pool furnace

Abstract

The invention discloses a method for replacing a feeder to ensure stable convection in a pool furnace. At least two feeders are arranged in the pool furnace; 1. Replace the feeder that needs to be replaced, and stop the work of the feeder that needs to be replaced. During the replacement, The unreplaced feeder works normally, and the opening remains unchanged; 2. After the replacement of the feeder to be replaced is completed, open the replaced feeder and start feeding; 3. After the feed amount is stable, compare the replaced feeder with the The size of the feed volume of the unreplaced feeder ensures that the feed volume difference of each feeder is within 5Kg; and simultaneously increases the feed volume of all feeders to restore the liquid level, and the recovery range of the liquid level is 0.5‑ 1.5mm / 4h; 4. When the liquid level returns to the required height, the feeding volume of all feeding machines will return to the normal working feeding volume. By reducing the height of the liquid level by a small amount, the large adjustment of the feeding amount is reduced to cause the convection instability of the pool furnace.

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 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. Affect the instability of stone and air bubble state....
