Abstract
The invention relates to an electrode extension rod jacket which belongs to a key part on equipment for producing nanometer bismuth oxide powder and is mainly formed by enclosing a semi-arm aluminum card board (1) and two small-arc aluminum card boards (2,3) in the length equal to half the arc length of the semi-arm aluminum card board (1), wherein the two small-arc aluminum card boards (2,3) are connected by tenon match, and connected with two edges of the semi-arm aluminum card board (1) by a temperature compensation device, and one arc edge of the semi-arm aluminum card board (1) is connected with a power supply bus joint/or feed cable joint (7) by a fixed bolt (6). The invention can satisfy the tight combination of electrode carbon rods or electrode extension rods in different circular degrees and automatically adjust the clamping stress along with temperature fluctuation to keep stable electric contact.
Description
Technical field
The present invention relates to a kind of parts of producing on the nano bismuth oxide powder equipment, is the electrode extension rod jacket on a kind of bismuth gasification furnace specifically.
Background technology
Utmost point extension bar chuck is the critical component that plays conduction and holding electrode effect in the bismuth gasification furnace equipment, and at present, the electrode carbon-point on existing bismuth gasification furnace or the electric arc all is to adopt the electrode fixed card to be electrically connected with cable to contact.Because arc furnace frequent start-stop furnaceman do, the heat of vaporizer tends to be delivered on the electrode fixed card of cable connection along electrode carbon-point, plunger contact, low when high when causing high temperature to be, fixed card is different with the thermal coefficient of expansion of plunger contact, produces nip stress and changes with temperature fluctuation.Time one is long, the connection of the two will be loosening relatively, directly cause electrode fixed card loose contact oxidation, the electrode carbon-point after oxidized or the circularity of plunger contact often produce irregular change of shape again, more aggravated the vicious circle of electrode fixed card loose contact, arc furnace work is played pendulum.
In order to address the above problem, on August 30th, 1989, Chinese utility model patent notification number CN2043742U disclosed the hot stove in a kind of ore deposit (arc furnace) electrode holde, locking device on it is by copper jaw, arc clamp and connecting rod retaining mechanism are formed, its connecting rod retaining mechanism adopts four connecting rods, adjust screw mandrel and hinge and form, four connecting rod generations under the tension of adjusting screw mandrel are cut fork power and are removed to push arc clamp locking electrode carbon rod or plunger contact, realize the clamping to electrode.Its complex structure does not still solve the problem that nip stress changes with temperature fluctuation
Summary of the invention
Technical problem to be solved by this invention is the above-mentioned shortcoming at prior art, a kind of electrode extension rod jacket is provided, this electrode extension rod jacket can satisfy the electrode carbon-point of different circularity or the tight amplexis of plunger contact, its nip stress is adjusted adaptively with the fluctuation of temperature, makes electric contact keep stable.
Technical scheme of the present invention can be implemented by following measure: a kind of electrode extension rod jacket, by a semicircular arc aluminium alloy clamp, two roundlet arc aluminium alloy clamps surround and combine, and the arc length of roundlet arc aluminium alloy clamp is half of semicircular arc aluminium alloy clamp arc length; Between two roundlet arc aluminium alloy clamps is to be connected by tenon, and the fillet of a roundlet arc aluminium alloy clamp wherein is cylindric tenon; The fillet of another corresponding piece roundlet arc aluminium alloy clamp is the circular arc tongue-and-groove; The roundlet arc aluminium alloy clamp and another fillet that the roundlet arc aluminium alloy clamp of circular arc tongue-and-groove is arranged of cylindric tenon are arranged, connect by temperature compensation means respectively and between the both sides fillet of semicircular arc aluminium alloy clamp; One end arc limit of above-mentioned semicircular arc aluminium alloy clamp connects power source bus joint/or feeder line cable joint by hold-down screw; Described temperature compensation means is by " worker " font location hole at roundlet arc aluminium alloy clamp middle part, " T " font location hole at semicircular arc aluminium alloy clamp middle part, and alignment pin, the back-moving spring of copper-manganese material and pin bolt are formed; Back-moving spring one end inserts in " worker " font location hole at roundlet arc aluminium alloy clamp middle part, and end compresses semicircular arc aluminium alloy clamp in addition; Alignment pin inserts from " T " font location hole and passes back-moving spring, and " worker " font location hole is connected with the pin bolt;
Compared with the prior art, when the present invention was connected with electrode carbon-point or plunger contact, three plate actings in conjunction of roundlet arc aluminium alloy clamp of adopting semicircular arc aluminium alloy clamp and two tenons to be connected were filled the span of a man's arms and are clamped the excircle of electrode carbon-point or plunger contact; Form 360 ° annular contact surface,, also can guarantee the electric contact area of big electric current even during the periphery circularity inaccuracy of electrode carbon-point or plunger contact.Retaining mechanism of the present invention adopts two cover alignment pins, the back-moving spring structure of copper-manganese material, electrode carbon-point or plunger contact become big with temperature rising diameter the time, electrode extension rod jacket has the trend of increase to the nip stress that it produced, because the back-moving spring of copper-manganese material has the characteristic that elastic force raises and lowers with temperature, offset the increase of a part of nip stress conversely adaptively, therefore overcome nip stress, made electric contact keep stable with the problem that temperature fluctuation changes; In addition, as long as unclamp pin bolt on the alignment pin, semicircular arc aluminium alloy clamp can separate under the effect of back-moving spring structure reliably with the roundlet arc aluminium alloy clamp that two tenons are connected, and has realized that maintenance changes the convenience of electrode.
