Description

Two arch glass spinning kilns

The utility model belongs to a kind of glass fibre production unit, particularly a kind of wire drawing kiln that adopts two arch heat exchange tank furnace fusion cast glass and directly it is supplied the drawn glass fiber.This wire drawing kiln especially is suitable for producing all kinds of glass fibre.

At present, adopting the direct method drawing process to produce glass fibre, is the more advanced production method of the common employing in home and abroad, also claims pool kiln wiredrawing.The major equipment of this method comprises unit kiln, metallic recuperator, main channel, subchannel (shaping channel) and bushing group etc., its process characteristic is that direct production goes out required various glass fibre after going into stove by glass batch, and has that operational path is short, energy consumption is low, the wire drawing quality is good, level of automation is high and produce characteristics such as comprehensive cost is lower.But have that one-time investment is big, product is single and be subjected to the influence of turn of the market big, defectives such as adaptive faculty difference.And traditional ball method crucible drawing process though have characteristics such as one-time investment is less, exists energy consumption height, production cost height and feed temperature stability and wire drawing are second-rate, and is difficult to form defectives such as scale and benefit.

The purpose of this utility model is a kind of pair of arch glass spinning kiln of design, with overcome background technology or one-time investment big, be subjected to the market restraining factors big; Or energy consumption height, production cost height and quality stability is poor, the disadvantage of scale and benefit difference.Thereby reach that one-time investment is less, energy consumption is lower, scale and benefit are moderate, good product quality, be easy to control and stable, to purposes such as turn of the market adaptability are stronger.

Solution of the present utility model is to adopt conventional glass furnace---two arch Heat Room tank furnaces as utensils such as blow-molded glass bottles, remove its rear face wall work pool afterwards to bottle-making machine kiln main body partly, as kiln body of the present utility model, with fusion cast glass liquid.Below the back face breastwork of kiln, the glass metal main channel of a band heating unit is set up in molten-glass pool uptake exit, glass metal is transported to each subchannel for platinum bushing and wire drawing unit drawn glass fiber.Therefore, the utility model comprises and contains Heat Room, port and be located at the burner of its underpart, and inside and outside big arch, sidepiece breastwork, flue, melting pool and base thereof, the glass metal uptake, forward and backward face wall is at interior kiln body; Key is that rear face wall bottom, the glass metal uptake exit end of kiln body also are provided with the glass metal main channel of a band combustion gas spout and spray gun group, also be provided with the glass metal subchannel in these both sides, main channel, also be provided with combustion gas spout and spray gun group thereof on top, subchannel, then be provided with platinum bushing group in its bottom; Glass metal main channel and rear face wall are fastened and connected and are integral, and its liquor inlet exports over against the glass metal uptake; Each glass metal subchannel inner chamber is also connected and is fastened and connected with its main channel inner chamber and is integral.The length and width ratio of above-mentioned kiln melting pool is 1.3～4.0, melting area 2～30m ², the pond is 300～1200mm deeply, glass metal uptake discharge area (wide * height) 200～600 * 100～300mm.And the described glass metal subchannel that also is provided with in both sides, glass metal main channel, two passages are the setting of " T " font each other, it is long to be respectively 4000～12000mm and 5000～18000mm, in the main channel or the subchannel tail end also be provided with exhanst gas outlet; And each channel lumen sectional area is (wide * height) 200～600 * 300～500mm, is positioned at metal level at each passage and establishes a combustion gas spout and corresponding gas gun with 200～400mm place, every interval, upper part.And described platinum bushing group, bushing is the platinum bushing that is not less than 800 holes.

The utility model is owing to adopt the kiln body of two arch recuperative tank furnaces as fusion cast glass liquid, and adopt main channel, subchannel to draw glass metal for big specification bushing and the wire drawing of wire drawing unit, its design is rationally advanced, the industrial scale regulation range is wide, power to adapt itself to the channing market is strong, and one-time investment is moderate, the cycle is short, and the glass metal quality is good, glass fibers quality height, unit consumption of energy is lower, can form characteristics such as scale production and remarkable in economical benefits.
