Description

Technical Field

[0001] The invention relates to the technical field of glass fiber tube processing, in particular to a glass fiber tube drying device. Background Art

[0002] As an inorganic non-metallic material with excellent performance, glass fiber tube has the characteristics of light weight, hardness, non-conductivity, high mechanical strength, anti-aging, high temperature resistance, and corrosion resistance. It is widely used in composite materials, electrical insulation materials, thermal insulation materials, circuit substrates and other fields; In the production process of glass fiber tubes, drying is an indispensable link, which directly affects the final quality and production efficiency of the product; the existing high-temperature ovens for glass fiber tubes have a baking chamber directly connected to the heating chamber, and the products to be dried are directly placed in the baking chamber, which easily causes heat loss, insufficient concentration of hot air flow, and slow product drying speed.

[0003] A Chinese patent discloses a new high-temperature oven for glass fiber insulation pipes (authorization announcement number CN216694226U). The patented technology starts the electric heating tube to heat the baking chamber, and at the same time starts the blower and blows air into the heating chamber through the air exhaust, so that the hot air in the heating chamber flows from the lower opening to the wind cavity. The hot air flows from bottom to top in the wind cavity, and the inner and outer walls of the insulation pipe placed in the wind cavity are heated and dried at the same time. The impurity gas generated when the insulation pipe is heated and dried rises with the hot air flow and finally flows into the confluence pipe from the upper opening and the air pipe. One end of the confluence pipe can be connected to the exhaust gas impurity removal device to filter and purify the exhaust gas to avoid environmental pollution; a filter box is fixed at one end of the blower air inlet pipe, and an activated carbon filter is fixed inside the filter box to filter dust and impurities in the external air; However, it has certain disadvantages: using the same activated carbon filter for a long time will cause excessive accumulation of dust and impurities on the activated carbon filter, thereby clogging the activated carbon filter and affecting the air circulation efficiency, which will not only reduce the drying efficiency, but also affect the drying effect, and requires frequent manual cleaning and maintenance of the activated carbon filter, increasing labor intensity.
