Abstract
The utility model provides a platinum crucible for basalt fiber drawing, belonging to the technical field of glass fiber drawing, in particular to the manufacturing field of platinum crucibles used for drawing, comprising a top cover 1, a feed pipe 2, a plurality of heating lugs 3, a platinum crucible body 4, and a plurality of expanding discharge spouts 5. The utility model is characterized in that: a baffle 6 is arranged in the platinum crucible body 4; a plurality of leaks 7 are positioned on the baffle 6. The utility model has the advantages of reasonable structure, easy and convenient manufacturing, solving the problems of uneven temperature in the crucible and easy crystallization at the discharge spout in high-temperature drawing, improving the productivity of the high-temperature fibers, and wide application in other high-temperature fiber drawing production besides in the basalt fiber production.
Description
(1) technical field
Relate to the glass fiber wire-drawing technical field, relate in particular to wire drawing and make the field with platinum crucible.
(2) background technology
Basalt fibre has good resistance to elevated temperatures; with it is the primitive fiber (mean diameter≤3 μ m) that raw material makes; all be better than glass wool and common ore deposit rock wool from common physicals to thermomechanical property greatly, be widely used in the thermal insulation protection at positions such as aircraft engine, instrument department, passenger cabin.It is the ideal lagging material of aircraft.
Basalt fibre generally is to be raw material with natural basalt stone, forms through the platinum crucible wire drawing by high temperature melting again.If but utilize common drawn glass fiber to draw it with platinum crucible, can run into many troubles.Because silicon oxide and alumina content are very high in the chemical constitution of natural basalt, the fusing point that causes it is often more than 1400 ℃, and is more much higher than general glass melting temperature.After cold burden directly added crucible from filling tube, it can cause the crucible baseplate temp inhomogeneous in the straight heavy the bottom of a pan, influences wire-drawing operation.In addition, its material is short, the crystallization ceiling temperature up to 1300 ℃ about, often because of crystallization causes fracture of wire, reduce production efficiency in wire drawing.
(3) summary of the invention
This utility model a kind of drawing basalt fibre platinum crucible is proposed, it can solve because the reinforced not even crystallization problem of the improper crucible baseplate temp that causes, raising basalt fibre production efficiency.
The utility model technical solution is as follows: it is by top cover 1, filling tube 2, heating ear 3, crucible body 4 and let slip a remark and 5 constitute, it is characterized in that: in crucible body 4, be provided with dividing plate 6, dividing plate 6 is provided with many small openings 7, and in addition, its 5 the exit diameter of leting slip a remark is greater than inlet diameter.
In general, temperature is higher near crucible heating ear 3 upper ends, after this is provided with a dividing plate 6, the cold burden of adding is stopped at this, falls into base plate again from small opening 7 after waiting to turn to small powder, thereby reduces the temperature difference of base plate, keeps the stable of wire-drawing operation.At the higher characteristics of basalt raw material crystallization ceiling temperature, former vertical barrel type let slip a remark 5 is designed to exit diameter greater than inlet diameter, so just can effectively avoid melt at the 5 place's crystallizatioies of leting slip a remark, and enhances productivity.Dividing plate 6 is designed to recessed poor formula, the small opening 7 φ=3-4mm on the dividing plate 6, and spacing is 5-8mm, line-spacing is 4-8mm.5 middle outlet diameter/inlet diameter=1.1-1.6/1 let slip a remark.
The drawing basalt fibre platinum crucible that adopts the utility model scheme to make, rational in infrastructure, be skillfully constructed.Solved the interior non-uniform temperature of crucible that the high temperature wire drawing often runs into, and the easy crystallization problem in place of leting slip a remark.Improved high temperature fiber production efficiency.This crucible also can be widely used in other high temperature fiber production of drawing except that being used to produce the basalt fibre.

(5) embodiment
It is 150 μ m basalt fibre production platinum crucibles that design has a daily output of 15 kilograms of diameters.The high 200mm of crucible, crucible height 350mm (the containing electrode) hole count of leting slip a remark is 100 holes.Near heating ear 3 upper ends, be provided with a recessed poor formula platinum dividing plate 6.Dividing plate 6 is provided with three row's small openings 7.Every small opening 7 Φ=4mm, pitch of holes is 5mm, row distance also is 5mm.Let slip a remark 5 for staged on the base plate, its inlet diameter is 1.2mm, and exit diameter is 1.4mm.With of the production of this crucible through one month, 5 places of leting slip a remark can be for a long time crystallization not, baseplate temp is even, produces reliable and stablely, meets the needs of production fully.
Claims (4)
1, draw the basalt fibre platinum crucible, be made of top cover (1), filling tube (2), heating ear (3) crucible body (4) and let slip a remark (5), it is characterized in that: be provided with dividing plate (6) in crucible body (4), dividing plate (6) is provided with many small openings (7); Let slip a remark the exit diameter of (5) greater than inlet diameter.
2, drawing basalt fibre platinum crucible according to claim 1 is characterized in that: dividing plate (6) is recessed poor formula, and it is arranged near heating ear (3) upper end, small opening (7) φ=3-4mm on the dividing plate (6), and spacing is 5-8mm, line-spacing is 4-8mm.
3, drawing basalt fibre platinum crucible according to claim 1 is characterized in that: let slip a remark (5) are one of following form: 1) staged; 2) horn.
4, drawing basalt fibre platinum crucible according to claim 1 is characterized in that: (5) middle outlet diameter/inlet diameter=1.1-1.6/1 lets slip a remark.
