Glass fibre is a kind of good insulating, thermotolerance is strong, erosion resistance good, the ceramic that physical strength is high.The production process of glass fibre is, first raw material is obtained glass melt after homogenizing, clarification in tank furnace, described glass melt enters bushing by operation access, and by the filtering net in bushing and let slip a remark and form stable glass melt stream, after described glass melt flows through refrigerating unit cooling, enter wire-drawing frame, obtain glass fibre through the traction of wire-drawing frame and stretching.Bushing is the thermosteresis of compensation glass melt in operation access in glass fibre preparation process, ensures that glass melt forms the key equipment of stable glass fibre.
At present, bushing uses the PtRh alloy of Rh content 10wt% ~ 20wt% to make usually, and such bushing tensile strength is high, and fusing point is high, is applicable to high-temperature service environment.Existing bushing generally includes: be laid on the filtering net above base plate, is arranged on leting slip a remark below base plate, is arranged on the thermopair on bushing sidewall and the electrode being arranged on base plate two ends.
Traditional technology is protecting platinum shield or coating powder and becoming toothpaste-like and spread upon on bushing, and with in mould material or high-temperature cement filling process, coating powder can come off, and cannot play the effect of protection platinum.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of glass bushing, and surface is provided with coating, reduces bushing loss, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of glass bushing, comprise flanged plate, the central position of described flanged plate is provided with rectangular through-hole, base plate is provided with directly over rectangular through-hole, the first-class pitch arrangement of base plate has multiple wire drawing hole, sloping core plate is provided with between the rectangular limit of base plate and the rectangular limit of rectangular through-hole, the other both sides side of described base plate and rectangular through-hole is provided with bulkhead, the both sides of base plate are provided with electrode, this glass bushing has conductive metal material to make, and the surface coverage of glass bushing has coating.
Preferably, the end of described electrode is provided with U-type groove.
Preferably, described wire drawing hole place is provided with sleeve pipe.
Preferably, the inner side between described bottom and sloping core plate is provided with stiffening web
Preferably, described rectangular through-hole place is provided with the filter screen of 100 mesh sieves, and filter screen removably connects relative to rectangular through-hole, and the edge of rectangular through-hole is provided with multiple groove, and the edge of described filter screen is provided with projection at correspondence position, and projection is stuck in groove.
Adopt the beneficial effect of above technical scheme to be: the glass bushing of the utility model structure, electrode, plays electrified regulation; Base plate, to glass liquid heating; Sloping core plate, heats and gains in strength; Flanged plate, the effect be connected with corundum brick; Stiffening web, increases the intensity of base plate, prevents distortion; Bulkhead, the effect of gaining in strength and heating; Wire drawing hole, glass fibre is shaping, and the rectangular through-hole place of flanged plate is provided with filter screen, impurity in glass metal is played to the effect of filtration, improve purity and the quality of glass, filter screen removably connects, convenient cleaning, the surface coverage of glass bushing has coating, reduces bushing loss.

Embodiment
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 and Fig. 3 show embodiment of the present utility model: a kind of glass bushing, comprise flanged plate 1, the central position of described flanged plate 1 is provided with rectangular through-hole 2, base plate 3 is provided with directly over rectangular through-hole 2, the first-class pitch arrangement of base plate 3 has multiple wire drawing hole 4, sloping core plate 5 is provided with between the rectangular limit of base plate 3 and the rectangular limit of rectangular through-hole 2, described base plate 3 is provided with bulkhead 6 with the other both sides side of rectangular through-hole 2, the both sides of base plate 3 are provided with electrode 7, this glass bushing has conductive metal material to make, and the surface coverage of glass bushing has coating.
The end of electrode 7 is provided with U-type groove 8, wire drawing hole 4 place is provided with sleeve pipe 9, inner side between bottom and sloping core plate 5 is provided with stiffening web 10, rectangular through-hole 2 place is provided with the filter screen 11 of 100 mesh sieves, filter screen 11 removably connects relative to rectangular through-hole 2, the edge of rectangular through-hole 2 is provided with multiple groove 12, and the edge of described filter screen 11 is provided with projection 13 at correspondence position, and projection 13 is stuck in groove 12.
The glass bushing of the utility model structure, electrode, plays electrified regulation; Base plate, to glass liquid heating; Sloping core plate, heats and gains in strength; Flanged plate, the effect be connected with corundum brick; Stiffening web, increases the intensity of base plate, prevents distortion; Bulkhead, the effect of gaining in strength and heating; Wire drawing hole, glass fibre is shaping, and the rectangular through-hole place of flanged plate is provided with filter screen, impurity in glass metal is played to the effect of filtration, improve purity and the quality of glass, filter screen removably connects, convenient cleaning, the surface coverage of glass bushing has coating, reduces bushing loss.
First water is coated with fine, soft fur brush toward bushing surface, again by 100 mesh sieve protecting platinum shield or coating powder is sieved on bushing uniformly, the bushing of coated is put into electric furnace sinter, temperature is spending insulation 2 hours to 1200 degree-1300, drop to 150 degree Deng furnace temperature to take out, bushing builds rear use with cement again.
Traditional technology one piece of 1200 hole bushing is after a life cycle completes, the loss of platinum rhodium is at about 200 grams, and this coating bushing is a loss 60-70 gram after the same life cycle completes, and platinum rhodium 130 grams saved by every platform kiln, about 30,000 5 thousand yuan, greatly reduce enterprise's production cost.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
