Protection device of glass kiln charging machine and glass kiln charging machine

Abstract

The invention relates to a glass kiln charging machine and a protection device thereof. The charging machine comprises a charging machine body, a spiral charging barrel arranged above the charging machine body and a hopper connected to the spiral charging barrel, and the spiral charging barrel is used for stretching into a charging opening in a charging wall of a glass kiln; the protection device comprises a heat insulation part fixedly installed on the spiral feeding barrel, the heat insulation part is located between the charging wall and a hopper, and an insulating part is arranged on the side, facing the charging wall, of the heat insulation part and used for being attached to the charging wall. Therefore, the heat insulation part can insulate radiant heat generated by the glass kiln, the heat is prevented from directly acting on the hopper and working parts of a charging machine, the hardening probability of powder in the hopper is greatly reduced, the melting quality of the glass kiln is improved, and related parts of the charging machine can be effectively protected. Meanwhile, the insulating part can prevent flames from jumping out and can also prevent the heat insulation part from making direct contact with the charging wall, and the insulativity of the charging machine and the kiln body is improved.

Description

technical field [0001] The present disclosure relates to the technical field of glass substrate production and manufacturing, and in particular, relates to a protective device for a glass furnace feeder and a glass furnace feeder. Background technique [0002] During the manufacturing process of OLED glass substrates, it is necessary to install the feeding machine on the feeding wall of the glass kiln for feeding operations. Since the radiant heat of the kiln feeding wall is around 85°C, when the feeder is installed on the feeding wall, the radiated heat will directly act on the hopper and the equipment body. On the one hand, the temperature rise of the hopper will cause the internal compound powder to compact and affect the stability of the feeding, and the feeding needs to be stopped when cleaning the powder compact, which will cause the furnace glass level to fluctuate and affect the quality of glass melting. On the other hand, long-term high-temperature operation of the...

AI Technical Summary

Problems solved by technology

On the one hand, the temperature rise of the hopper will cause the internal mixed powder to harden, which will affect the stability of the feeding, and the feeding needs to be stopped when cleaning the powder hardened, which will cause fluctuations in the glass level of the furnace and affect the quality of glass melting

On the other hand, long-term high-temperature operation of the equipment body will accelerate the aging and damage of the screw rod, transmission bearing, and seal.
