Abstract
The utility model relates to a furnace door tube for a hydrogen burning furnace. The furnace door tube for the hydrogen burning furnace comprises a tube body; a gas inlet connecting tube which is communicated with a cavity of the tube body is arranged on the tube body. A flange is arranged at one end, at which the gas inlet connecting tube is arranged, of the tube body. A cooling water jacket is welded circularly on the tube body. The right side of the cooling water jacket is connected with the flange. A water inlet connecting tube is arranged on the lower left side of the cooling water jacket. A water outlet connecting tube is arranged on the right upper side of the cooling water jacket. The water inlet connecting tube and the water outlet connecting tube are communicated with the cavity of the cooling water jacket. A furnace door is arranged at the left end of the tube body and the furnace door is connected with the tube body through a bolt. The furnace door tube for the hydrogen burning furnace provided by the utility model is simple in structure, and a furnace core tube and the furnace door tube are connected separately, so that the trouble that integral change is needed is avoided when the furnace core tube is changed, labor and material resources are saved, and the changing cost is reduced. The tube body is provided with the cooling water jacket, so that the furnace door is cooled better, transfer of high temperature to an inlet and an outlet is prevented and production and operation are carried out conveniently.
Description
Technical field:
The utility model relates to a kind of hydrogen-burning stove, relates in particular to a kind of hydrogen-burning stove and uses the fire door pipe.
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 hydrogen-burning stove is used the fire door pipe, comprises body, and body is provided with the inlet mouth pipe connecting; Said inlet mouth pipe connecting leads to the inner chamber of body, and body is provided with a flange at an end of inlet mouth pipe connecting, on the body around being welded with a watercooling jacket; The right side of watercooling jacket is connected with flange; Left downside at watercooling jacket is provided with the water-in pipe connecting, and the upper right side 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; Left end at body is provided with fire door, is connected with body through screw.
Further, the material of said body and watercooling jacket is a heat-resistance stainless steel.
The beneficial effect of the utility model is: the utility model is simple in structure, and furnace core tube adopts separable the connection with the fire door pipe, needs the trouble of integral replacing when having avoided changing furnace core tube, has practiced thrift manpower and materials, has reduced replacement cost; And on 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.
Description of drawings:
The structural representation of Fig. 1 the utility model embodiment.
Embodiment:
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation:
Its design agents mechanism comprised body 1 when a kind of hydrogen-burning stove of the utility model was implemented with the fire door pipe; Body 1 is provided with inlet mouth pipe connecting 7; Inlet mouth pipe connecting 7 leads to the inner chamber of body 1, and body 1 is provided with a flange 2 at an end of inlet mouth pipe connecting 7, on the body 1 around being welded with a watercooling jacket 3; The right side of watercooling jacket 3 is connected with flange 2; Left downside at watercooling jacket 3 is provided with water-in pipe connecting 6, and the upper right side of watercooling jacket 3 is provided with water outlet pipe connecting 8, and water outlet pipe connecting 8 and water-in pipe connecting 6 all lead to the inner chamber of watercooling jacket 3; Left end at body 1 is provided with fire door 5, is connected with body through screw.Body 1 all uses the heat-resistance stainless steel material with watercooling jacket 3.
