Design method of molten glass flow channel

Abstract

The invention discloses a design method of a molten glass flow channel, which comprises a flow channel, a kiln front wall, a kiln tank bottom, a baffle brick and a refractory material, wherein a pit with a height difference is formed at the kiln tank bottom; the kiln front wall is arranged at the front end of the pit in a molten glass incoming direction; the rear end of the pit and a flow channelmain path form a 45 DEG obliquely upward channel; the 45 DEG obliquely upward channel is connected with the flow channel main path; the kiln front wall is connected with an obliquely upward brick wallarranged in the middle of the pit; the flow channel main path is further internally provided with the baffle brick; and a tank bottom and a tank wall of the flow channel are attached with the refractory material. The design method has the benefits that molten glass can be forced for convection and homogenization; an upper layer and a lower layer of the molten glass are intensively and uniformly mixed; a temperature difference between the upper layer and the lower layer of the molten glass is reduced; the viscosity of the molten glass is uniform; the operating efficiency is improved; and the production cost is lowered.

Description

technical field [0001] The invention relates to a device before glass wire drawing in glass production, in particular to a design method of a glass liquid flow path. technical background [0002] The drawing line in the glass tank kiln is the basis for the production of ECR ​​glass fiber. The ECER reinforced fiber produced by our company is a high-performance fiber with high Tex technology content. However, the wire drawing operation in fiber production is unstable, and the current design of the flow hole is designed parallel to the bottom of the kiln pool, resulting in a large temperature difference between the upper and lower layers of glass flowing into the passage, the upper layer of glass with high temperature and low viscosity and the lower layer with low temperature and high viscosity The glass cannot be fully mixed, and the glass with uneven viscosity will cause temperature difference of the bushing when it reaches the bushing, and it is difficult to adjust, and the ...

Problems solved by technology

However, the wire drawing operation in fiber production is unstable, and the current design of the flow hole is designed to be parallel to the bottom of the kiln pool, resulting in a large temperature difference between the upper and lower layers of glass flowing into the passage, the upper layer of glass with high temperature and low viscosity and the lower layer with low temperature and high viscosity The glass cannot be fully mixed. The glass with uneven viscosity will cause the temperature difference of the bushing when it reaches the bushing, and it is difficult to adjust. The drawing operation has been abnormal.
