Abstract
The utility model provides a suction tube type discharging device for a rare earth metal electrolytic furnace. A micro vacuum pump and a receiving container are placed on a trolley; the front end of a molybdenum tube is extended into a molybdenum crucible, and the tail end of the molybdenum tube is connected with the micro vacuum pump by virtue of a PU (Polyurethane) tube; a handle is arranged on an obtuse-angle bent part of the molybdenum tube, and an opening is formed in an acute-angle bent part of the molybdenum tube; a sealing cover is arranged at the middle segment of the molybdenum tube close to the opening, and can be used for sealing the opening by means of suction force when the micro vacuum pump is in a non-running state; when the micro vacuum pump is in the non-running state, the sealing cover is opened automatically under the action of gravity; a manually-reset high-temperature cutoff switch is arranged at the tail end of the molybdenum tube close to the opening, and is connected with the micro vacuum pump through an electric wire; when the temperature is over 100 DEG C, the power supply of the micro vacuum pump can be cut off. By adopting the suction tube type discharging device, fluctuation of the furnace temperature is reduced, product defects due to fluctuation of the furnace temperature are overcome, the electrolysis time is prolonged effectively, and the labor intensity is lowered. Meanwhile, the suction tube type discharging device is simple in structure, and low in manufacturing cost.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of hydrocone type drawing mechanism for re metal electrolyzing stove.
Background technology
The most fluoride system electrolytic process that adopt of rare earth metal are produced, and are placed with molybdenum crucible, for the liquid rare earth metal out of catholyte on splendid attire in conventional electrolytic furnace.Generally, every about 1 hour, need artificial taking-up after liquid rare earth metal, then continue electrolysis operation.Concrete steps are: upper negative electrode is risen, and remove a segment distance, be convenient to furnace operating, stretch in stove with crucible tongs, clamp molybdenum crucible, and move on to outside stove, pour out liquid rare earth metal, empty molybdenum crucible is put in electrolytic furnace, continue electrolysis operation.Taking out in the process of liquid rare earth metal, there is following problem: one, interrupt electrolytic process, in stove, temperature changes, and affects quality product; Two, belong to high-temperature service, labour intensity is large; Three, crucible temperature is up to 1000 degree, if crucible rollover may cause the security incidents such as burn.
At present, in rare-earth trade, oneself has and adopts siphon principle to carry out the device that electrolytic process goes out metal to be used.As: the Chinese patent (patent No.: 01209185.5) disclose a kind of " electrolytic tank siphon discharger for fluorine compounds molten rare earth salts ", its motor platform is to be placed on drive lead screw by driving nut, and drive lead screw and double-speed motor are linked togather to realize by step-down gear and move up and down.This device motor platform lifting process is not steady, poor accuracy.And for example: the Chinese patent (patent No.: 200520127615.7) disclose " a kind of device for discharging metal for rare-earth metal production by siphon principle ", this goes out metal device and mainly forms by going out metal car, hydraulic efficiency system, controlling box, lifting of lifting table system, pumped vacuum systems and casting chamber.But all there is the shortcomings such as complex structure, manufacturing cost are higher in above two kinds of Patent equipments.
Summary of the invention
The utility model is high in order to overcome manufacturing cost, and the defects such as complex structure provide a kind of hydrocone type drawing mechanism for re metal electrolyzing stove.
Scheme of the present utility model is: a kind of hydrocone type drawing mechanism for re metal electrolyzing stove, comprise molybdenum pipe, handle, opening, sealing cover, PU pipe, minipump, high temperature cut-off switch, container connects material, walkie fork lift truck, electric wire, wherein minipump and the container that connects material are positioned on walkie fork lift truck, the front end of molybdenum pipe stretches in molybdenum crucible, end is managed with minipump and is connected by PU, an obtuse angle place of molybdenum pipe is provided with handle, a sharp bend place is provided with opening, be positioned at the position that molybdenum pipe stage casing approaches opening and be provided with sealing cover, sealing cover can be because suction seals opening in the time of micro vacuum pump work, in the time of micro vacuum air pump inoperative because sealing cover gravity is opened automatically, the position that approaches opening at molybdenum pipe end is provided with the high temperature cut-off switch of hand-reset, high temperature cut-off switch is connected with minipump by electric wire, in the time that temperature exceedes 100 ℃, can cut off micro vacuum pumping source.
The utility model beneficial effect is: can liquid rare earth metal successfully be taken out from electrolytic furnace by pull of vacuum and follow-up molten metal deadweight, reduce labour intensity, reduce furnace temperature fluctuation and avoided the product that may cause because of furnace temperature fluctuation bad, and improved effective electrolysis time, there is feature simple in structure, low cost of manufacture simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of hydrocone type drawing mechanism for re metal electrolyzing stove, comprise molybdenum pipe 1, handle 2, opening 3, sealing cover 4, PU pipe 5, minipump 6, high temperature cut-off switch 7, container 8 connects material, walkie fork lift truck 9, electric wire 10, wherein minipump 6 and the container 8 that connects material are positioned on walkie fork lift truck 9, the front end of molybdenum pipe 1 stretches in molybdenum crucible, end is managed 5 by PU and is connected with minipump 6, an obtuse angle place of molybdenum pipe 1 is provided with handle 2, a sharp bend place is provided with opening 3, be positioned at the position that molybdenum pipe 1 stage casing approaches opening 3 and be provided with sealing cover 4, sealing cover 4 can be because suction seals opening in the time that minipump 6 is worked, in the time that minipump 6 is not worked because sealing cover 4 gravity are opened automatically, the position that approaches opening 3 at molybdenum pipe 1 end is provided with the high temperature cut-off switch 7 of hand-reset, high temperature cut-off switch 7 is connected with minipump 6 by electric wire 10, in the time that temperature exceedes 100 ℃, can cut off minipump 6 power supplys.
In the time producing, first by walkie fork lift truck 9 near electrolytic furnace, the front end of molybdenum pipe 1 is inserted in molybdenum crucible, adjust the position of walkie fork lift truck 9, make the opening 3 at molybdenum pipe 1 sharp bend place be positioned at the container 8 that connects material directly over, and distance is suitable, open minipump 6, sealing cover 4 is closed with instrument, liquid rare earth metal is drawn onto in molybdenum pipe 1, in the time that liquid rare earth metal approaches high temperature cut-off switch 7, because temperature raises, high temperature cut-off switch 7 auto-breakings, minipump 6 quits work, sealing cover 4 is opened automatically, liquid rare earth metal connects material in container 8 because siphonic effect flows to automatically.In the time that liquid rare earth metal has taken out, by handle 2, molybdenum pipe 1 is improved, the liquid rare earth metal in molybdenum pipe 1 and electrolyte flow be to connecting material in container 8, whole discharging end of processing.
