Description

Negative pressure clarification platinum channel device Technical Field The utility model relates to the technical field of glass production, in particular to a negative pressure clarification platinum channel device. Background In the melting process of glass, all the physical dissolved gas in the glass liquid melt and tiny bubbles mixed in the glass body are required to be discharged out of the carrier glass melt, so that high-quality solution is obtained, and high-quality carrier glass is produced. The kiln process melts the batch into a molten glass and then generates a large amount of volatile substances such as bubbles. The glass liquid is sent into a glass liquid channel for clarification and adjustment, then sent into a forming process to be made into carrier glass or semi-finished products with other shapes, and finally finished products are obtained after post-processing. In the clarification process, the glass liquid simultaneously has the effects of homogenizing, clarifying and eliminating bubbles. At present, the high temperature required in the clarifying and bubble removing process provides higher requirements on the physical structure and the service life of a clarifying pipe section of the glass liquid channel body, and long-time high-temperature operation can seriously influence the service life of the glass liquid channel body and cause deformation and collapse of the top of the clarifying pipe section due to improper use. In addition, as for the negative pressure clarifying device and the clarifying method of the platinum channel with the patent number of CN202210894838.4, the gas of the glass solution is discharged through negative pressure, and the negative pressure pump is needed to be used for generating the gas, the gas generated by the glass solution is corrosive, and the corrosive gas flows through the negative pressure pump for a long time, so that the corrosion to the internal components of the negative pressure pump can be generated, the service lives of the negative pressure pump and a system connected with the negative pressure pump are influenced, and the production process of the carrier glass is seriously influenced.
