Abstract
The invention provides a new method for filling the insulation filling of the electric heat pipe. The characteristic of the method is to save the commonly used ducts, and adopt a positioning piece with certain geometry and good insulation and thermal conductivity, so that it can obviously improve the center degree of the electric heat wire in the electric heating tube, and ensure and improve the electricity of the product. Gas performance, saving a large number of ducts used in 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, saving operation field.
Loading method in the past roughly has following two kinds:
(1) method of employing conduit: (seeing figure mono-)
First heating wire (5) is penetrated to 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 metal sleeve (4), and leading-off rods (1) is fixed on to the lower end of metal sleeve (4) through limit plug (3) with nut (2), rely on location lug (8) to ensure the concentricity of heating wire (5) and metal sleeve (4), then pour into insulation filler (6) in the upper end of metal sleeve (4), vibrations limit, limit upwards proposes conduit (9), until fill comprehensively.
This method is owing to always having some gaps between conduit (9) and metal sleeve (4) and between conduit (9) and heating wire (5), and these gaps are just caused heating wire (5) always can not be positioned at well the center of metal sleeve (4) and affected the electric property of product.Meanwhile, first such loading method will have the conduit that different in size, thickness differs in a large number.Secondly, factory is also had to certain requirement, at least will have two times of above height of metal sleeve length of being loaded, therefore this loading method is all made troubles to production management and factory building construction.
(2) do not adopt catheter method: (seeing figure bis-)
In metal sleeve (4), put into the heating wire (5) that connects leading-off rods (1), (7), 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 location of the self-dependent elasticity tension of heating wire (5) and up and down leading-off rods (1), (7) and remain on the center of metal sleeve (4).Filler powder flows in metal sleeve (4) by the aperture in fixture (10) under metal sleeve (4) Vibration Condition.
This kind of structure, the only larger situation of suitable metal sleeve pipe and leading-off rods elastic stiffness shorter, heating wire.If metal sleeve and extraction tube are longer, only relying on upper and lower two ends fixing is inadequate with one heart, therefore usually occurs that heating wire can not affect electric property at 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 ensure the centrad of heating wire.
The present invention completes like this: before heating wire packs metal tube into, first on heating wire, put several and have the keeper of certain geometrical shape, be that its profile is made imaging triangle, oval, concave arc triangle, concave arc quadrangles etc. are the keeper of shape like that, to pack in metal tube and can form the passage that allows insulation filler pass through, keeper overall dimension 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 like this to each position of heating wire, then to keeper processing, it is fixed on resistance wire no longer moves.Again leading-off rods is loaded onto in one end of the resistance wire that is fixed with keeper, penetrate metal sleeve, install rubber stopper, be fixed on one end of metal sleeve.Then, again the metal sleeve that heating wire is housed is contained in and on powder filling support, the other end of heating wire is loaded onto to leading-off rods and be fixed on support, pour into insulation filler with powder filling device again, fill with on shake limit, limit, completes the filling work of insulation filler after filling with rubber stopper plug jail.
The present invention can just make heating wire correctly be fixed on center, especially the electrothermal tube manufacture to long size of metal tube without conduit, only needs suitably to increase keeper and just can ensure good insulation properties and the thermal conductivity between heating wire and 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 using in a large amount of production, and makes simplified control.
Fig. 1 is longitudinal cross-sectional schematic of employing conduit filling method in the past.
Fig. 2 is the longitudinal cross-sectional schematic without the filling method of conduit in the past.
Fig. 3 is longitudinal 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, for embodiment, invention is described in further detail.
First the keeper of quantity (11) distance in accordance with regulations is on demand enclosed within to heating wire (5) upper, keeper (11) is processed, keeper (11) is packed tightly on heating wire (5).Then load onto leading-off rods (1) and (7) at heating wire (5) two ends, penetrate metal sleeve (4), put rubber stopper (3) in 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, the metal sleeve (4) that this is equipped with to heating wire (5) is contained on powder filling device, with the vibrations limit powder filling of powder filling device limit insulation filler is filled after, the electrothermal tube of filling insulation filler (6) is unloaded from powder filling device, put rubber stopper (13) and packing ring (14) and screw on nut (15), whole powder filling work has just been accused.
Claims (1)
1. the fill method of an electrothermal tube insulant, it is characterized in that first on heating wire (5), putting several keepers (11), this keeper (11) has size and is slightly larger than the centre bore of heating wire (5), profile is done triangularity, oval, concave arc triangle, the geometries such as concave arc quadrangle, make to pack into the passage that can form insulation filler in metal tube, then there is the heating wire (5) of keeper (11) to process to cover, it is fixed on heating wire (5), pack heating wire (5) into metal sleeve (4) again, be contained on powder filling device, fill insulation filler.
