Abstract
The utility model discloses a nitrogen gas supply device which comprises a gas storage reservoir and a nitrogen gas bottle. At least two gas inlet connecting pipes and one gas outlet connecting pipe are arranged on the gas storage reservoir. Gas inlet pipes are fixedly connected on the gas inlet connecting pipes. The gas inlet pipes are connected with a pressure-reducing valve on the nitrogen gas bottle via gas pipe quick joints. A gas outlet pipe is fixed connected on the gas outlet connecting pipe, and a gas pipe quick joint is connected at the other end of the gas outlet pipe so as to realize the quick connection with a desulphurization molten iron ladle. The nitrogen gas supply device realizes continuous nitrogen gas supply when the porous-plug nitrogen gas blowing agitation method is adopted for the desulphurization treatment on the continuously-produced or large-volume high-temperature molten iron of nodular cast iron in the casting production, thereby ensuring that the desulphurization treatment is carried out normally and continuously without interruption, and has the advantages of simple structure and easy use.
Description
Technical field
The utility model relates to the Foundry Production technical field, and especially a kind of energy nitrogen without interruption is used for Foundry Production and carries out the nitrogen air feeder that desulfurization is handled.
Background technology
Continuous expansion along with the foundry goods range of application, people also improve day by day to the requirement of foundry goods use properties, especially for the spheroidal graphite cast iron of making important spare part, content to wherein objectionable impurities sulphur must be strict controlled in the very low scope, the sulphur of too high amount can make the nodularization effect of spheroidal graphite cast iron descend, reduce the mechanical property of foundry goods, need that therefore molten casting iron is carried out the desulfurization processing and just can meet the demands.Using the most extensive effective desulfuration processing method at present is porous plug nitrogen blowing paddling process, promptly the reducing valve by nitrogengas cylinder connects desulfurization bag that the root tracheae directly feeds molten iron and carries out desulfurization and handle, this simple method is more suitable for small-sized or single foundry goods, but in the time of will carrying out desulfurization and handle continuous production or jumbo molten iron, nitrogen amount does not often satisfy the production usage quantity, as suspend desulfurization and handle, handle again after treating to change nitrogengas cylinder again, can cause the high temperature liquid iron fast cooling, have a strong impact on sweetening effectiveness, do not reach technical requirements, after molten iron being melted down intensification, carry out the desulfurization processing again, will upset normal rhythm of production, reduce production efficiency, increase the casting cost.
The utility model content
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of nitrogen air feeder is provided, solving in the foundry production, the continuous air feed problem of nitrogen when continuous production or jumbo spheroidal graphite cast iron high temperature liquid iron are adopted porous plug nitrogen blowing paddling process to carry out desulfurization to handle.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of nitrogen air feeder, comprise gas storage bag and nitrogengas cylinder, gas storage is wrapped and is provided with two air inlet tubes and an outgoing gas connection tube at least, be fixedly connected with inlet pipe on the air inlet tube, inlet pipe is connected with reducing valve on the nitrogengas cylinder by the tracheae hydraulic quick coupler, be fixedly connected with escape pipe on the outgoing gas connection tube, the escape pipe the other end is connected with the tracheae hydraulic quick coupler, be connected with the desulfurizing iron bag by the tracheae hydraulic quick coupler, molten iron carried out desulfurization handle.
For easy to use, layout is attractive in appearance, and described air inlet tube and outgoing gas connection tube are separately positioned on the relative both sides of gas storage bag; In order to be connected firmly, described inlet pipe is fixed on the air inlet tube by the tracheae clamp, and escape pipe is fixed on the outgoing gas connection tube by the tracheae clamp.
In addition, place for ease of moving, the utility model also comprises support, and the gas storage bag can be fixed on the support.
The beneficial effects of the utility model are that the utility model is simple in structure, and is easy to use, when the replacing nitrogengas cylinder, because the nitrogen transition temporarily of storage is used in the gas storage bag, thereby can not influence normally carrying out continuously of desulfurization processing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
1. gas storage bags, 2. nitrogengas cylinders, 2.1 reducing valve, 3. supports, 4. air inlet tubes, 5. outgoing gas connection tubes, 6. inlet pipe, 7. escape pipes, 8. tracheae clamps, 9. tracheae hydraulic quick couplers among the figure
Embodiment.
With preferred embodiment the utility model is further described in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of nitrogen air feeder as depicted in figs. 1 and 2, comprise gas storage bag 1 and nitrogengas cylinder 2, also comprise a support 3, gas storage bag 1 is fixed on the support 3, convenient moving carried, gas storage bag 1 is welded by weldless steel tube and two end plates, assurance has enough resistance to air loss and resistance to pressure, gas storage bag 1 is provided with two air inlet tubes 4 and four outgoing gas connection tubes 5, two air inlet tubes 4 and four outgoing gas connection tubes 5 are arranged with respect to gas storage bag medullary ray zygomorphy, be fixedly connected with inlet pipe 6 on the air inlet tube 4, be fixedly connected with escape pipe 7 on the outgoing gas connection tube 5, inlet pipe 6 is fixed on the air inlet tube 4 by tracheae clamp 8, escape pipe 7 is fixed on the outgoing gas connection tube 5 by tracheae clamp 8, the other end of inlet pipe 6 and escape pipe 7 is connected with the tracheae hydraulic quick coupler 9 with self-enclosed function respectively, inlet pipe 6 is connected with reducing valve 2.1 on the nitrogengas cylinder 2 by tracheae hydraulic quick coupler 9, after opening the reducing valve 2.1 on the nitrogengas cylinder 2, nitrogen just can be stored in the gas storage bag 1, in order to using, the desulphurised hot metal bag quantity that escape pipe 7 can be handled is as required selected, one or several escape pipes 7 are connected with the desulphurised hot metal bag by tracheae hydraulic quick coupler 9, just can carry out desulfurization to molten iron has handled, present embodiment can carry out desulfurization to four desulphurised hot metal bags simultaneously to be handled, behind the work certain hour, show by the indicator gauge of observing reducing valve 2.1 on the nitrogengas cylinder 2, when nitrogen pressure is not enough, tracheae hydraulic quick coupler 9 on available another inlet pipe 6 is connected with new nitrogengas cylinder 2, then the nitrogengas cylinder 2 of sky is unloaded and change, because the nitrogen transition temporarily that stores in the gas storage bag 1 is used, thereby normally carrying out continuously of can guaranteeing that desulfurization handles and not interrupting, prevent to produce the pause of production process.
