[0002] In the substrate glass production process, the pool furnace glass melting is a key link, and the pool furnace raw material after melting needs to be continuously fed into the subsequent process by means of the continuous conveyor, so as to guarantee the continuity of production. However, in the process of the glass raw material flowing through the continuous conveyor, the following problems exist:

[0003] The glass raw material has certain viscosity and adhesion, and is extremely easy to adhere to the screw blades of the continuous conveyor and the internal parts of the conveyor which are difficult to clean during the conveying process. Due to the irregular adhesion of the raw material, the center of gravity of the continuous conveyor is offset, and the equipment is out of balance. During the operation, the unbalanced state produces great vibration and noise, which not only affects the stability and service life of the equipment, but also has adverse effects on the working environment of the operators.

The traditional sealing method has poor sealing effect when facing the special properties of the glass raw material, and the dust leakage at the tail often occurs. The dust leakage at the tail not only causes waste of the glass raw material and increases the production cost, but also seriously pollutes the working environment of the production workshop and endangers the health of the operators.
