Melting device for glass fiber production

The invention discloses a melting device for glass fiber production. The melting device comprises a channel-type melting tank. The upstream end of the melting tank is a melting zone, and a closed feeding mechanism is arranged at the port of the upstream end. The downstream end of the melting tank is provided with a melting-down zone, the tail end of the melting tank is provided with a clarification tank, and a smoke exhaust pipeline is arranged at the top of the melting tank. and a vibration defoaming mechanism is arranged in the clarification tank. According to the invention, a large amount of volatile gas generated by high-temperature melting is effectively prevented from overflowing from a discharge port, so that the volatile gas is prevented from entering a working environment to cause irreversible damage to the respiratory system of a worker; and through vibration bubble removal, the bubble content of a molten glass solution is reduced, the quality of glass fibers is improved, the use amount of a clarify
