Kiln for glass fiber cloth production

Abstract

The invention discloses a kiln for glass fiber cloth production, and relates to the technical field of glass fiber cloth production. The kiln comprises a glass kiln, an observation hole is formed in the left side surface of the glass kiln, a shielding device is arranged on the inner wall of the observation hole, glass liquid is arranged in the glass kiln, the shielding device comprises a trapezoidal groove, the trapezoidal groove is formed in the inner wall of the observation hole, two rotating devices are fixedly connected on the inner wall of the trapezoidal groove, and U-shaped plates are arranged on the outer walls of the rotating devices. According to the kiln for glass fiber cloth production, the observation hole is shielded under the combined action of a rotating shaft, a bearing, the U-shaped plates, a baffle plate, a contact block and a spring, so that the observation hole cannot be blocked by easily flying powder and solid cooled by other easily volatile substances, the inside of the glass kiln is conveniently observed by a worker through a heat radiation lens and a laser thermodetector, and great convenience is provided for the worker.

Description

technical field [0001] The invention relates to the technical field of glass fiber cloth production, in particular to a kiln for glass fiber cloth production. Background technique [0002] Fiberglass grid cloth is untwisted roving plain weave fabric, which is an important base material for hand lay-up FRP. The strength of the grid cloth is mainly in the warp and weft directions of the fabric. For occasions requiring high warp or weft strength, it can also be woven into a single Directional cloth, it can arrange more rovings in the warp or weft direction, single warp direction cloth, single weft direction cloth. [0003] Glass fiber cloth is made of glass balls or waste glass as raw materials, which are melted at high temperature in the kiln and then processed in the later stage. The traditional technology is to open a horizontal observation hole on the wall of the kiln pool at the position to be observed. However, due to the combination of broken glass The material contains...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a kiln for the production of glass fiber cloth, which solves the problem of easily flying powder and other volatile substances. Due to the decrease of temperature, the state will change from gaseous state to liquid state and solid state in sequence. In the end, the melt will adhere to the surface of the horizontal observation through hole, which is not conducive to the observation results of thermal radiation lens, laser thermometer and other hole equipment. It needs to be cleaned manually, which is difficult and easy to damage the pool wall. causing great inconvenience
