A brushed bushing for basalt fiber processing

Abstract

The invention relates to the field of basalt fiber processing equipment, and discloses a wire drawing bushing for basalt fiber processing, including a bushing shell, a bottom plate, a nozzle, an electrode, a preheating plate and reinforcing ribs, and the bottom plate is arranged on the bushing The bottom of the casing and the two sides of the bottom plate are electrically connected to two opposite electrodes, and the bottom of the bottom plate is provided with leaking nozzles arranged at equal distances. By setting two preheating plates in the leaking plate shell, using the preheating plates to heat the flowing melt, the melt to be drawn is heated evenly and fully, and the depth of the bottom plate leaking nozzle is also reduced, so that when the drawing work is in progress, the effective Ensure that the melt to be drawn above the bottom plate is heated sufficiently and evenly, and the depth of the leak nozzle is small, which causes little impact on heat exchange. While not affecting the effect of melt outflow, it avoids crystallization and blockage of the leak nozzle due to insufficient melt temperature Internal problems, while clogs located at the spout are easy to clear.

Description

technical field [0001] The invention relates to the field of basalt fiber processing equipment, in particular to a drawing bushing used for basalt fiber processing. Background technique [0002] Basalt is an inorganic silicate that has been tempered over fire and in a furnace to change from hard rock to soft fiber. Compared with glass fiber, its material has thermal conductivity, low hygroscopicity, corrosion resistance, With excellent properties such as radiation resistance and high crack resistance and excellent processing performance, it is often used to make high-end products. In the process of basalt fiber processing, the drawing bushing is an indispensable fiber drawing equipment. [0003] The working principle of the existing fiber drawing bushing is as follows (refer to image 3 ): The basalt melt enters the cavity inside the drain plate shell 1, and energizes the two electrodes 3 on both sides of the bottom plate 2, so that the bottom plate 2 heats the upper melt, a...

Problems solved by technology

[0004] However, the existing wire drawing bushing heats the basalt melt through the bottom plate 2, the heat of the upper and lower layers of the melt located in the bushing shell 1 is uneven, and the melt flows quickly through the drain nozzle 201 under the force of gravity, resulting in uneven heating of the melt. Sufficient, affecting the effect of wire drawing, when the depth of the nozzle 201 is increased to ensure that the melt is sufficiently heated for wire drawing, because the existing wire drawing bushing is equipped with a cooling mechanism at the bottom of the bottom plate 2, so that the wire drawing melt Rapid cooling and molding, at this time, the depth of the leak nozzle 201 is relatively long, and the heat exchange caused by the operation has a great influence, and the temperature of the solution flowing through the bottom plate cannot be guaranteed to be uniform, which affects the solution outflow effect, resulting in crystallization and leak nozzle blockage. And it is difficult to clean the blockage located in the leak nozzle, which leads to the inability to carry out the work of the drawing bushing
