Abstract
The utility model relates to a heating body and specifically relates to a heating body of a vacuum resistance furnace. The heating body comprises a heating body cylinder, wherein at least two inner conductive rings are arranged on the inner wall of the heating body cylinder along the axial direction, outer conductive rings corresponding to the inner conductive rings are arranged on the outer wall of the heating body cylinder, and electrode joints are arranged on the outer conductive rings. The heating body cylinder of the heating body disclosed by the utility model is manufactured by conductive heating body film cloth, thereby having the advantages of low price, low using quantity, simplicity and reliability in assembly and more uniform heating. As the conductive rings adopt conical contact surfaces, the clamping between the conductive rings and the heating body film cloth can become tighter and tighter, the connection is reliable, a two-phase power supply or a three-phase power supply can be selected according to needs, free temperature control is facilitated, and the current among all sections on the heating body can mutually pass through a shaft, the applicability to the power supply is enhanced, and the mutual inductance shock is eliminated.
Description
Technical field
The utility model relates to a kind of heater, is specifically related to a kind of vacuum resistance furnace heater.
Background technology
The vacuum resistance furnace heater mainly comprises at present: monotubular formula, bar rod connect composite type, guipure structure etc.; Wherein monotubular formula heater is on whole shape barrel, to process groove; To form current circuit; Power up after-current and flow through current circuit and generate heat, this structure can only be used for small-sized heater, and the lower and warpage of large-scale heating material utilance more seriously, does not have big specification tube material available yet yet.It is that rod, strip conductive heating unit are connected to form the heater that current circuit is made through connector that rod connects composite type; This structure is because tie point is a lot; Can produce mutual inductance between the rod when electric current is crossed the heater rod and very big vibrations take place; Thereby the destruction tie point causes loose contact to cause equipment fault, so equipment failure rate is very high.Guipure structure heating body generally adopts refractory metal to be processed into net, belt shape; Guipure is fixed in powers up heating in the stove; This structure is simple relatively, but because the refractory metal cost is very high, and in stove, be easy to infiltrate other impurity and become fragile; Brittle failure takes place, so reliability is not high yet, use cost is also higher.
Summary of the invention
The utility model is high to present vacuum resistance furnace heater failure rate, and the problem that the working service cost is high proposes high, the with low cost heating element structure of a kind of reliability.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of vacuum resistance furnace heater comprises the heater tube, and heater tube inwall upper edge is axially arranged with at least two interior conducting rings, and the heater drum outer wall is provided with and the corresponding outer conducting ring of interior conducting ring, and outer conducting ring is provided with electrode nipple.
Said heater tube is processed by conductive heating unit film cloth.
Conducting ring is conical contact face with the contact-making surface of outer conducting ring and heater tube in said.
The utility model heater tube is processed by conductive heating unit film cloth, and heater film cloth is cheap, consumption is few, assembling is simple and reliable; Because heater is a tubular, has played water conservancy diversion and sealing process, has saved the guide shell structure; Because heater forms surface current on heating film cloth, it is more even to generate heat; Because conducting ring adopts conical contact face, conducting ring and heater film cloth holder can be more and more tighter, connect reliable; Outer conducting ring is provided with electrode nipple, can select two phases, three phase mains as required for use, can conveniently carry out the free temperature control of each section branch warm area; The mutual axis of electric current on the heater between each section, the mutual inductance vibrations of having avoided the heater electric current to cause strengthen the power supply applicability, have eliminated the mutual inductance concussion.

Embodiment
As shown in Figure 1, the utility model structural representation, a kind of vacuum resistance furnace heater comprises heater tube 1, heater tube 1 is processed by conductive heating unit film cloth, can piece together to be rolled into tubular or to select for use whole tubular material to cut with conductive heating unit film cloth to form; Heater tube 1 inwall is provided with at least two interior conducting rings 2 vertically, can for two, three or more, heater tube 1 outer wall is provided with and interior conducting ring 2 corresponding outer conducting rings 3; Conducting ring adopts heat-resistant conductive material to process; Inner and outer ring cooperates clamping heater tube, and the inner and outer ring clamp structure is the self-locking structure, and it is tightr to be tending towards clamping in stresses such as gravity, vibrations, heating cylindrical shell tractives; Interior ring can conveniently be pegged graft for integral type or split-type structure; Outer conducting ring 3 is provided with electrode nipple 4, and conducting ring and electrode nipple 4 are drawn power connection points outside the stove, can select multiple different circuit connecting mode as required; When the utility model uses, be suspended on through conducting ring outside the top on the dielectric support block 5 of body of heater 6 inboards, the top electrodes ring has played the effect of suspending whole heater tube in midair simultaneously; As shown in Figure 2, interior conducting ring 2 is conical contact face with the contact-making surface of outer conducting ring 3 and heater tube.
When the utility model specifically uses, at first assembling the utility model, is example as connecting heater with three sections triangles, and its assembly program is:
(1) select for use graphite paper to be wound into the high 2400mm graphite of diameter 1200mm paper web;
(2) the conducting ring outer shroud is a ring structure, and interior ring is selected two lobe formula structures for use;
(3) with frock the graphite paper web is suspended in midair, keep paper web vertical, each position flattens; (4), the graphite paper web is vertically called in four groups of outer shrouds with four groups of coaxial stacking of outer shroud; (5) by putting into conduction ring in the paper web, and with go up most one group of outer shroud and cooperate clamping graphite paper web;
(6) sling the graphite paper web and go up to connect first group of conducting ring to the second group conducting ring and paper web connecting portion after be connected last second group of conducting ring;
(7) connect third and fourth group conducting ring successively by above-mentioned operation;
(8) conducting ring hangs in heater in the furnace chamber after connecting completion, will go up one group of conducting ring most and be articulated on the insulation supporting seat, removes frock, and the unnecessary graphite paper web that prunes away is connected the electrode bar on the conducting ring with the electrode nipple of getting involved furnace shell;
(9) will connect from the furnace shell outside heater tube topmost, connect three of three phase mains respectively with middle two arrays of electrodes rod behind bottom two electrode bar short circuits and extremely go up, this moment, assembled just can come into operation.
