Abstract
The utility model provides a tank furnace wiredrawing device adopting a double-crown glass furnace, belonging to the glass fiber production equipment. The device comprises a furnace body, a wiredrawing mechanism and a glass melt ascending channel, wherein the furnace body includes a heat exchange chamber, a small furnace, a burner of the small furnace, a primary molten pool, a secondary molten pool, an internal crown and an external crown; the wiredrawing mechanism includes a main glass melt channel, forming channels with bushing groups, a gas jet and jet gun groups which are arranged on the main glass melt channel and the forming channels, a flue gas emission hole, a dirty material discharge hole and a bearing support. As the primary and secondary convective molten pools are arranged, the device increases the residence time of the glass melt in the high temperature zone, the convection intensity, diffusion area and concentration gradient of the glass melt, the melting rate of the furnace in unit area, the quality of the glass melt and the temperature of the glass melt in the channels, the glass fiber output can be improved by over 10% and the comprehensive energy consumption can be reduced by about 15%; therefore, the device is characterized by effectively improving the quality, grade and output of the glass fiber products and reducing the energy consumption and production cost, etc.
Description
Technical field
The utility model belongs to a kind of glass fibre production unit, particularly a kind of pool kiln wiredrawing device that adopts double arched kiln stove fusion cast glass liquid and directly be drawn into glass fibre.This glass furnace especially is fit to adopt the direct method wire drawing to produce glass fibre.
Background technology
At present, adopting the direct method drawing process to produce glass fibre is the production method that generally adopt the home and abroad, also claims pool kiln wiredrawing.At notification number is that CN2485306Y, name are called the patent documentation of " two arch glass spinning kiln ", disclose to contain Heat Room a kind of comprising, and port and burner thereof, melting pool, inside and outside big arch is at interior kiln body; Containing glass metal main channel, bottom is provided with the subchannel (shaping channel) of platinum bushing group and is located at combustion gas spout and corresponding spray gun group on two passages, fume emission hole and resting support be at interior wire-drawing mechanism, and the glass metal rising passway that the glass metal main channel is communicated with melting pool.Characteristics such as though it is less that this kiln has one-time investment, operational path is short, and energy consumption is low, can be than ball farad silk energy saving technology more than 2/3, and production cost is low.But because two arch glass furnaces of its fusion cast glass liquid only are provided with a melting pool (district), the residence time of glass metal in the high-temperature zone is short, the glass metal convection intensity is low, and diffusion area and concentration gradient are little, and the melting rate of kiln unit surface and glass metal quality are low; Can only be used for the lower rove of production technology and specification of quality defectives such as (silks).
Summary of the invention
The purpose of this utility model is the defective that exists according to back of the body technology, improve a kind of pool kiln wiredrawing device that adopts two arch glass furnaces of design, with the melting rate of the residence time, convection intensity, diffusion area, concentration gradient and the kiln unit surface of raising glass metal in the high-temperature zone and the quality of glass metal, and the temperature of the interior glass metal of each passage of wire-drawing frame.Finally reach the melting rate of grade, quality and the kiln unit surface of effective raising fiberglass products, cut down the consumption of energy and purpose such as production cost.
But solution of the present utility model is with the melting pool (district) in two arch glass furnaces of former fusion cast glass liquid by a melting pool that increases to two convection current on basis of background technology, when prolonging the residence time of glass metal in the high-temperature zone, improve the melting rate of its convection intensity and kiln unit surface and the quality of glass metal; Thereby realize its goal of the invention.Therefore, the utility model comprises and contains Heat Room, port and burner thereof, melting pool, in, (greatly) arch is at interior kiln body with contain the glass metal main channel outward, the bottom is provided with the shaping channel (subchannel) of platinum bushing group, be located at combustion gas spout and corresponding spray gun group on two passages, fume emission hole and resting support are at interior wire-drawing mechanism, and the glass metal rising passway that the glass metal main channel is communicated with melting pool, it is characterized in that melting pool is before the kiln axis, the master that the back is provided with, but the melting pool of secondary two convection current, main, be provided with a partition wall that is lower than glass metal between the secondary melting pool, the two ends of partition wall and bottom link into an integrated entity with the both walls and the melting pool bottom of melting pool respectively.
The above-mentioned partition wall that is lower than glass metal, its partition wall upper surface are lower than the normal height of metal level 100~250mm in the melting pool.And described major and minor melting pool is 3: 1.8~2.2 along the length ratio of kiln axis direction, the dark 100~250mm of the more main deeply melting pool in the pond of secondary melting pool, and the width in two ponds is identical.For the long-term quality of glass metal in main channel and shaping channel that keep, also have additional dirty material discharge outlet in the bottom, main channel.
The utility model is owing to increase to two melting pools of convection current mutually with melting pool by traditional one, thereby both prolonged the residence time of glass metal in the high-temperature zone, improved the convection intensity of glass metal again, diffusion area, the melting rate of concentration gradient and kiln unit surface and the quality of glass metal, and the temperature of glass metal in the material road, compare with the background technology of same specification model, its comprehensive energy consumption descends about 15%, thereby glass fibre output can improve more than 10%. have the quality that can effectively improve fiberglass products, grade and output, and the melting rate of kiln unit surface, cut down the consumption of energy and characteristics such as production cost.
