Fixing structure and mode of glass fiber pathway bushing brick

Abstract

The invention relates to a fixing structure and a fixing mode of a glass fiber pathway bushing brick, and belongs to the technical field of glass fiber forming. The fixing structure is mainly characterized in that: a bushing brick frame is arranged at the bottom of the bushing brick; the outside periphery of the bushing brick has a double-layer step-shaped structure; the top of the bushing brick frame has a corresponding single-layer step-shaped structure; the bushing brick frame is arranged on the lower surface of a pathway base plate through a bushing brick frame supporting hook; the fixing mode comprises the following steps of: arranging the bushing brick in the bushing brick frame, arranging the bushing brick and the bushing brick frame on the lower surface of the pathway base plate by the bushing brick frame supporting hook by using bolts, and arranging a bushing system on the lower surface of the pathway base plate by a bushing frame supporting hook. By the fixing structure and the fixing mode, damage of the bushing brick, which is caused by replacement of a bushing can be reduced effectively, production efficiency and product quality can be improved, the glass fiber pathway bushing brick can be replaced and assembled by the fixing structure and matching with other tools, replacement time is shortened, and operation staff are reduced.

Description

Technical field [0001] The invention relates to a fixing structure and a fixing method of a glass fiber passage leakage plate brick, belonging to the technical field of glass fiber molding. Background technique [0002] The production of glass fiber as a reinforcing fiber in a glass fiber composite product is a process in which the molten glass melted in the furnace is pulled out by the winding equipment below it to form fine fibers through the leakage plate installed in the passage part of the furnace. The slat is a long and narrow container with many through holes. The molten glass passes through the slats and the holes of the slats, and then becomes thinner, and the monofilaments are coated with sizing agent and bunched to form a glass fiber bundle. The leakage plate is supported by the leakage plate frame and the casting material, and the leakage plate frame is installed under the passage through bolts. [0003] Due to the extremely high temperature and strong corrosiveness o...

Problems solved by technology

[0006] In order to ensure the safety of the operation and the close combination of the plug-in board and the plug-in brick surface when replacing the plug-in board, the plug-in board bricks need to be cooled and mechanically treated. During this period, the plug-in board bricks will be subjected to thermal shock and additional stress. Due to the nature of the material of the brick, cracks will occur in the leaky bricks subjected to thermal shock and additional stress. When the molten glass passes through the liquid hole, a certain tension will be generated on the leaky bricks, which will cause displacement of the cracked bricks, and the cracks will develop into Larger gaps, so that the molten glass will flow into it and leakage will occur, and the molten glass flowing into the gap will be cooled by the surrounding environment and the viscosity will increase, which will affect the homogeneity of the molten glass

[0007] At the same time, during the replacement of the slatted bricks, the extra stress of the slatted bricks due to mechanical treatment will damage them, causing part of the slatted bricks to fall off and affect their functions, and the dropped part of the slatted bricks will hurt the operators below them. security incident

[0008] Furthermore, when the plug-in brick has to be replaced due to the above reasons, since the design of the original plug-in brick support hook only has the function of horizontal adjustment, the replaced plug-in brick will be affected in the longitudinal direction due to the thermal expansion of the passage refractory brick. The limitation of displacement caused by the difference of the coefficient makes it impossible for the plug-in brick to achieve the best cooperation with the flow material transfer above it and the plug-in device below the plug-in brick.
