Glass fiber drawing machine with uniform heating

Abstract

The invention discloses a glass fiber drawing machine with a uniform heating function. The machine comprises a wire drawing machine, a discharge pipe is fixedly connected to the input end of the wiredrawing machine; the input end of the discharge pipe is fixedly connected with the melting chamber; a heating device is fixedly mounted on the melting chamber; the input end of the melting chamber isfixedly connected with the impurity removal device; the outer side of the impurity removal device is covered with a charging box; the impurity removing device comprises a filtering device and a magnetic metal removing device; according to the glass fiber drawing machine, the wire drawing machine is directly connected with the melting chamber and the impurity removing device; the raw materials arecontinuously subjected to impurity removal and melting treatment, consumption of treatment equipment is reduced, consumption of cost resources is reduced, meanwhile, an asbestos heat preservation layer and a heat insulation sleeve are arranged on the outer side of the discharging pipe, heat preservation conveying of the molten raw materials is guaranteed, heat loss is prevented, and the raw materials are kept in a molten state all the time.

Description

Technical field: [0001] The invention relates to the field of glass fiber production, in particular to a glass fiber drawing machine with uniform heating. Background technique: [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and circuit board in various fields of national economy. [0003] In the existing glass fiber drawing device, generally two sets of equipment are required for raw material melting and raw material removal, which directly brings about a lar...

AI Technical Summary

Problems solved by technology

[0003]In the existing glass fiber drawing device, generally two sets of equipment are required for raw material melting and raw material removal, which directly brings about a large consumption of cost resources, and the raw material Contains other large particles of impurities, which cannot be directly removed for magnetic separation metal debris, which will directly damage the filter screen, resulting in a large number of fractures or damages in the subsequent glass fiber drawing, which seriously affects the production efficiency
