Abstract
The invention provides a kind of electrothermal tube filling insulation filler new method, the characteristics of this method are to have saved the conduit that generally adopts at present, and employing has the keeper of certain geometrical shape and good insulation performance and heat conductivility, thereby can obviously improve the centrad of heating wire in the electrothermal tube, guarantee and the electric property that improves product, save the conduit that uses in a large amount of the production.
Description
The present invention relates to a kind of loading method of improved electrothermal tube insulation filler, particularly can guarantee the centrad of heating wire and simplify the loading method of loading operation, save operation place.
Loading method in the past roughly has following two kinds:
(1) method of employing conduit: (seeing figure one)
Earlier heating wire (5) is penetrated external diameter than in the little conduit (9) of metal sleeve (4) internal diameter, the outer wall of conduit (9) has several location lugs (8).The conduit (9) that is installed with heating wire is inserted in the metal sleeve (4), and leading-off rods (1) passed limit plug (3) is fixed on metal sleeve (4) with nut (2) lower end, rely on location lug (8) to guarantee the concentricity of heating wire (5) and metal sleeve (4), pour into insulation filler (6) in the upper end of metal sleeve (4) then, while shaking conduit (4) is upwards proposed, till filling comprehensively.
This method is because between conduit (9) and the metal sleeve (4) and between conduit (9) and the heating wire (5) some gaps are always arranged, and these gaps are just caused heating wire (5) always can not be positioned at the center of metal sleeve (4) well and influenced the electric property of product.Simultaneously, such loading method at first will have conduit different in size in a large number, that thickness differs.Secondly, factory is also had certain requirement, the height of metal sleeve length more than two times of being loaded will be arranged at least, therefore this loading method is all made troubles to production management and factory building construction.
(2) do not adopt catheter method: (seeing figure two)
Put into the heating wire (5) that connects leading-off rods (1), (7) in the metal sleeve (4), lower end leading-off rods (1) relies on fixture (3) to make lower end leading-off rods (1) concentric with metal sleeve (4), and the self-dependent elasticity tension of heating wire (5) and up and down leading-off rods (1), (7) the location and remain on the center of metal sleeve (4).The filler powder flows in the metal sleeve (4) by the aperture in the anchor clamps (10) under metal sleeve (4) vibration situation.
This kind structure, the only bigger situation of elastic stiffness of short, the heating wire of suitable metal sleeve pipe and leading-off rods.If metal sleeve and extraction tube are longer, only relying on that two ends are fixing up and down is not enough with one heart, and therefore heating wire usually occurring can not influence electric property at the metal sleeve center.
Task of the present invention is the loading method that a kind of improved electrothermal tube insulation filler will be provided, and it not only can save conduit but also can guarantee the centrad of heating wire.
The present invention finishes like this: before heating wire is packed metal tube into, on heating wire, put earlier the keeper that several have certain geometrical shape, the overall dimension of keeper is slightly less than the internal diameter of metal sleeve, the size of its centre bore is slightly larger than the outside dimension of heating wire, can easily keeper be seated in each position of heating wire like this, then keeper is handled, it is no longer mobile that it is fixed on the resistance wire.One end that will be fixed with the resistance wire of keeper is again loaded onto leading-off rods, penetrates metal sleeve, installs rubber stopper, is fixed on an end of metal sleeve.Then, the metal sleeve that heating wire will be housed again is contained on the powder filling support, the other end of heating wire is loaded onto leading-off rods be fixed on the support, pours into insulation filler with the powder filling device again, irritate while shaking, after filling, promptly finish the filling work of insulation filler with rubber stopper plug jail.
The present invention can just make heating wire correctly be fixed on the center of metal tube without conduit, especially to the electrothermal tube manufacturing of long size, only needs suitably to increase keeper and just can guarantee good insulation properties and thermal conductivity between heating wire and the metal sleeve.Loading method as compared with the past, it has not only obviously improved the centrad of heating wire, and can save the conduit that uses in a large amount of the production, and makes simplified control.
Fig. 1 is vertical cross-sectional schematic of employing conduit filling method in the past.
Fig. 2 is in the past without vertical cross-sectional schematic of the filling method of conduit.
Fig. 3 is vertical cross-sectional schematic of one embodiment of the invention.
Fig. 4 is several geometries of the keeper (11) that adopts of the present invention.
Below in conjunction with accompanying drawing, invention is described in further detail for embodiment.
At first the keeper of quantity (11) distance in accordance with regulations is enclosed within on the heating wire (5) on demand, and keeper (11) is handled, and keeper (11) is packed tightly on heating wire (5).Load onto leading-off rods (1) and (7) at heating wire (5) two ends then, penetrate metal sleeve (4), put rubber stopper (3) in the lower end, be fixed on the lower end of metal sleeve (4) with packing ring (12) and nut (2) together with rubber stopper (3).Then, this metal sleeve (4) that heating wire (5) are housed is contained on the powder filling device, after insulation filler is filled on powder filling ground while shaking with the powder filling device, the electrothermal tube that to fill insulation filler (6) unloads from the powder filling device, put rubber stopper (13) and packing ring (14) and screw on nut (15), whole powder filling work is just accused and is finished.
Claims (3)
1, a kind of fill method of electrothermal tube insulant, it is characterized in that on heating wire [5], being equipped with the keeper [11] of the fixed-site of assurance heating wire [5] at metal sleeve [4] center, this keeper [11] has good electrical insulation properties and heat conductivility, its overall dimension is slightly less than the internal diameter of metal tube [4], and its central hole size is slightly larger than the external diameter of heating wire [5].
2, loading method according to claim 1 is characterized in that the profile of keeper (11) can be done geometries such as triangularity, ellipse, concave arc triangle, concave arc quadrangle.
3, loading method according to claim 1 is characterized in that: keeper (11) is to make with material contracting with heat.
