Abstract
The utility model relates to a lamp filament hydrogen furnace which comprises a furnace body. A furnace core tube penetrates through the furnace body. The furnace core tube comprises a heating tube arranged in an inner cavity of the furnace body and furnace door tubes at two ends outside the furnace body, a lamp filament penetrates through the furnace core tube, an electric heating wire is wound on the outer wall of the heating tube in the inner cavity of the furnace body, two ends of the heating tube are provided with a flange plate respectively, a flange is respectively arranged at the contact positions between the furnace door tube at two ends of the furnace body and the furnace body, the furnace door tubes and the heating tube are fixedly connected through the flanges and the flange plates, and thermal insulation bricks are positioned on the inner wall of the furnace body. The lamp filament hydrogen furnace is reasonable in structural design, the thermal insulation bricks are arranged in the furnace body to enable hydrogen temperature to be easy to remain, and the heating tube and the furnace door tubes are connected through flanges and can be detachably dismounted so as to avoid troubles whole replacement of the heating tube, save labor and materials and reduce replacement cost. Cooling water jackets are arranged on the furnace door tubes so as to well cooling a furnace door, preventing high temperature from being transferred to an inlet/outlet and facilitate production operation.
Description
Technical field:
The utility model relates to a kind of hydrogen-burning stove, relates in particular to a kind of filament hydrogen-burning stove.
Background technology:
In bulb and luminescent lamp, all contain filament, filament is generally all formed by the tungsten filament spirally-wound, and in order to make coiled filament typing and not oxidation, the typing of must in hydrogen-burning stove, annealing is annealing in hydrogen atmosphere and handles.The key that annealing in hydrogen atmosphere is handled is the concrete structure design of hydrogen-burning stove equipment, and the key of hydrogen-burning stove equipment is furnace core tube, and the furnace core tube of existing hydrogen-burning stove equipment is the body of an integral body; Be included in the heating tube part in the hydrogen-burning stove, also comprise the fire door tube portion that stretches out outside the hydrogen-burning stove two ends, body is just very long like this; Because long-time hot operation can cause heating tube breakage, the metamorphism partly in the hydrogen-burning stove, and the fire door pipe damages not; But when changing furnace core tube, need integral replacing, and replacing is not only very inconvenient, and the fire door pipe is changed in the lump also; Waste a lot of manpower and materials, cost is bigger.
The utility model content:
The technical problem that the utility model will solve is the above-mentioned deficiency to prior art, provides a kind of easy to use, can realize the cooling processing well and use the fire door pipe with the isolating hydrogen-burning stove of furnace core tube.
For solving the problems of the technologies described above, the utility model adopts following technical scheme to be:
A kind of filament hydrogen-burning stove comprises body of heater, has crossed furnace core tube in the body of heater; Furnace core tube comprises the fire door pipe at the heating tube that is positioned at the body of heater inner chamber and the outside two ends of body of heater; Passed filament in the furnace core tube, the outer wall that is positioned at the heating tube of body of heater inner chamber is wound with electrical heating wire, and the two ends of heating tube respectively are provided with a ring flange; The position of the fire door Guan Zaiyu body of heater contact at body of heater two ends also respectively is provided with a flange, fixes that through flange and ring flange fire door pipe and heating tube are linked together; The inwall of body of heater is provided with insulating brick.
The fire door pipe is provided with the inlet mouth pipe connecting; The inlet mouth pipe connecting leads to the inner chamber of fire door pipe; Around being welded with a watercooling jacket, an end of watercooling jacket is connected with flange on the fire door pipe, is provided with the water-in pipe connecting at the downside of watercooling jacket; The upside of watercooling jacket is provided with the water outlet pipe connecting, and water outlet pipe connecting and water-in pipe connecting all lead to the inner chamber of watercooling jacket; The other end at the fire door pipe is provided with fire door, through screw and fire door pipe coupling.
The beneficial effect of the utility model is: the reasonable in design of the utility model, be provided with insulating brick in the body of heater, and the annealing in hydrogen atmosphere temperature in the hydrogen-burning stove is maintained easily; Heating tube adopts flange to be connected separable mounting or dismounting with the fire door pipe, needs the trouble of integral replacing when having avoided changing heating tube, has practiced thrift manpower and materials, has reduced replacement cost; And on the fire door body, being provided with watercooling jacket, realization fire door cooling that can be good has stoped high temperature to transmit to the gangway, has made things convenient for production operation.
