Abstract
The utility model relates to a rotating-preventing type vacuum furnace water-cooling electrode which comprises a compression bolt, a press plate, a mouth stopping ring and a furnace body connection pipe. The middle of a copper electrode is welded with a fixed flange provided with a rectangle positioning groove. A boss of the mouth stopping ring is correspondingly arranged in the rectangle positioning groove of the fixed flange, and is fixed with the furnace body connection pipe through the compression bolt and the press plate. According to the anti-rotating type vacuum furnace water-cooling electrode, the radial direction of the copper electrode is limited, and the copper electrode can not turn. Force-bearing condition of heating elements is greatly improved, service life of the heating elements is guaranteed, manufacturing and using cost is greatly reduced, structure sealing is reliable, and using requirements of a vacuum furnace is guaranteed.
Description
Technical field
The utility model relates to a kind of Rotaryproof vacuum drying oven water cooled electrode.
Background technology
Water cooled electrode is the important component part on the vacuum drying oven, and it is that heating element heater in the stove is linked to each other with stove dispatch from foreign news agency cable (or copper bar), transmits the transition member of large electric current, mainly is comprised of copper electrode, cooling water pipe, sealing ring, insulating part, bolt etc.With molybdenum bolt or graphite bolt heating element heater is linked to each other with an end of water cooled electrode in the stove; Stove dispatch from foreign news agency cable (or copper bar) links to each other with the other end of water cooled electrode.For about 1500 ℃ vacuum drying oven, heating element heater selects the materials such as molybdenum band, molybdenum filament or graphite to make usually, and this type of heating element heater plasticity is poor, and is more crisp, the stressed rear damage that easily causes.
The installation order of connection is generally, and first with the heating element heater in stove assembling and fixing, the furnace interior of copper electrode in the exit of heating element heater and the water cooled electrode is divided to be connected again, and then the stove with copper electrode partly is connected with cable (or copper bar) outward.Because vacuum drying oven is generally the low-voltage, high-current power supply, the specification of the cable (or copper bar) that stove is outer is larger, when connecting stove dispatch from foreign news agency cable (or copper bar), the structure of existing water cooled electrode can't guarantee that the copper electrode of water cooled electrode does not rotate, thereby cause the electrode tip of heating element heater stressed, make the heating element heater local damage that is attached thereto, because properties of materials, can't repair, cause whole to scrap.
The utility model content
The technical problem that the utility model solves provides a kind of rotation phenomenon of copper electrode in installation process in the water cooled electrode that solve; effectively protected heating element heater; prolong the service life of element, greatly reduced the Rotaryproof vacuum drying oven water cooled electrode of manufacturing and use cost.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
A kind of Rotaryproof vacuum drying oven water cooled electrode, comprise cooling water pipe, copper electrode, connection copper bar, cooling water pipe is arranged in the copper electrode, heating element heater in one end of copper electrode and the body of heater is connected, the outer part of the stove of copper electrode with is connected the copper bar connection, its special character is: also comprise hold-down bolt, pressing plate, take over seam ring, the body of heater of boss, the middle part of copper electrode is welded with the mounting flange with the rectangle locating slot, the boss correspondence of seam ring is arranged in the rectangle locating slot of mounting flange, and takes over fixing by hold-down bolt, pressing plate and body of heater.
Above-mentioned body of heater is provided with cover for seat on taking over, and is provided with insulation and seal in the cover for seat.
Compared with prior art, the utility model can't be rotated so that the copper electrode of water cooled electrode radially limits, greatly improved the stressing conditions of heating element heater, guaranteed the service life of heating element heater, greatly reduced and make and use cost, sealing structure is reliable, guarantees the vacuum drying oven instructions for use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises cooling water pipe 1, copper electrode 2, connects copper bar 3, cooling water pipe 1 is arranged in the copper electrode 2, heating element heater 11 in one end of copper electrode 2 and the body of heater 10 is connected, the outer part of the stove of copper electrode 2 with is connected copper bar 3 connections, its special character is: also comprise hold-down bolt 4, pressing plate 5, take over 9 with seam ring 6, the body of heater of boss, the middle part of copper electrode 2 is welded with the mounting flange with the rectangle locating slot, and the boss correspondence of seam ring 6 is arranged in the rectangle locating slot of mounting flange and takes over 9 fixing by hold-down bolt 4, pressing plate 5 and body of heater.
Above-mentioned body of heater is taken on 9 and is provided with cover for seat 7, is provided with insulation and seal 8 in the cover for seat 7.
During installation, the end that the heating element heater 11 in copper electrode 2 and the body of heater 10 links to each other, insulation and seal 8 that the material of successively packing into is respectively polytetrafluoroethylene (PTFE) and nitrile rubber together are inserted in 7 cover for seat again, then are fixed in the body of heater adapter 9; Outside the stove, in the seam ring 6 corresponding rectangular channels that insert on the copper electrode 2 middle part mounting flanges with boss, take over 9 with body of heater and fix by pressing plate 5, hold-down bolt 4, not only will insulate and seal 8 compressions, also so that the copper electrode 2 of water cooled electrode radially limited, can't rotate, greatly improve the situation that has been subjected to of heating element heater, guarantee the service life of heating element heater.
