Abstract
Description
Technical Field
[0001] The utility model relates to the field of drying equipment, in particular to a traction roller for a glass fiber drying furnace and a glass fiber drying furnace. Background Art
[0002] The fiberglass weaving preparation workshop requires the fiberglass cloth to be impregnated with oil before drying. The impregnation oil is liquid polytetrafluoroethylene. Because the polytetrafluoroethylene attached to the fiberglass cloth is adhesive and requires surface uniformity after oiling, it is crucial to prevent accidental adhesion during the drying process. Currently, a tall drying furnace is used, with traction rollers used to achieve the drying process. To ensure proper drying before leaving the furnace, the furnace is built 35 meters high, and the vehicle speed can only reach 8 meters per minute to ensure sufficient time for drying in one round trip. This results in high manufacturing costs for the drying furnace and the high construction costs of the 50-meter-high factory building.
[0003] Secondly, due to the strong adhesion of PTFE during the conversion process from liquid to solid, the traction rollers will stick to the PTFE in the drying furnace. After a single shift, a layer of PTFE sizing will form on the traction roller surface, affecting the fabric surface. Therefore, the machine must be stopped every one or two shifts for cleaning. However, the post-solidification PTFE cleaning process is extremely troublesome. It requires waiting for the drying furnace to cool naturally before manually climbing up a 35-meter high furnace to clean it. This not only creates efficiency issues but also carries risks for personnel, and the most important factor is the enormous energy costs. A drying furnace weighs 20-30 tons, and the temperature must be lowered from 300 degrees Celsius to room temperature each time, and then raised back up to 300 degrees Celsius for the next use. This makes continuous production impossible, resulting in enormous energy costs. Utility Model Content

[0005] The purpose of this utility model is achieved through the following technical measures:
[0006] A traction roller for a glass fiber drying furnace includes a traction roller body, characterized in that the traction roller body includes a traction outer roller and an inner filling roller, the inner filling roller is sleeved in the traction outer roller and a water guide cavity is formed between the two, and external pipes are respectively provided at both ends of the traction outer roller, the external pipes are connected with a sealed rotary joint for connecting cooling water, the external pipes are connected to the water guide cavity and guide the cooling water to flow through the water guide cavity between the traction outer roller and the inner filling roller.
[0007] As a preferred solution, a plurality of partition columns are provided between the inner filling roller and the traction outer roller. The partition columns are evenly distributed between the inner filling roller and the traction outer roller and make the thickness of the water guide cavity uniform.
[0008] In this application, by embedding a water pipe into the furnace body to introduce the traction roller, the traction roller temperature is maintained below 90°C, at which the polytetrafluoroethylene (PTFE) does not stick. To save energy and improve cooling efficiency, an inner liner is embedded in the roller body to reduce the gap between the inner liner and the inner wall of the roller. This maintains a constant cooling water flow rate and improves the cooling effect. The water flows through the water pipe and then through a rotary joint into the roller body. The inner liner is secured to the roller body by welding.
