Abstract
The utility model relates to the field of an iron alloy smelting submerged arc furnace, in particular to a submerged arc furnace shell with annular slag iron smoke collecting function. The submerged arc furnace comprises a submerged arc furnace shell, wherein the side surface of the submerged arc furnace shell is provided with a tap hole and a slag hole; the annular flue is provided with a pneumatic flap valve at the position of the iron outlet and the slag outlet; and an insulating flange butted with the dust removal pipeline is arranged on the side surface of the annular flue. Simple and reasonable structure, provides loose operation space for stokehold operation and is convenient for operation. The pipeline installation is greatly reduced, the input cost is greatly reduced, and the manufacture, the installation, the maintenance and the overhaul are all easy. The insulation point position is reduced, and the insulation reliability is enhanced.
Description
Technical Field
The utility model relates to the field of an iron alloy smelting submerged arc furnace, in particular to a submerged arc furnace shell with annular slag iron smoke collecting function.
Background
In the prior art, the furnace shell of the submerged arc furnace adopts a cylinder design form, a rib plate is welded on the outside, and a refractory material is built inside. The hot stove outer covering in ore deposit generally has two slag notch and two tapholes, can produce a large amount of flue gases at tapping, slag tapping in-process, seriously influences the regional operational environment of tapping, brings health hazard for operating personnel. For solving this problem, adopt at present and set up the mode of dust collecting cover respectively alone on tapping, slag notch upper portion, send the flue gas of collecting to the dust remover after merging through the pipeline and carry out purification treatment, though the collecting function of flue gas can be realized to this mode, nevertheless has following drawback: 1. an independent dust collection cover is designed on the upper part of each slag iron hole, and each dust collection cover corresponds to one flue gas pipeline and converges into a main dust removal pipeline. The complicated and intricate pipelines occupy the operating space in front of the furnace, and the problems of inconvenient operation of the tapping equipment and the like are often caused. 2. Too many flue gas pipelines result in large system construction cost and is not economical. 3. Because the way of each flue gas pipeline is insulated, the point positions are too many, and the flue gas pipeline is unsafe.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide the submerged arc furnace shell with the annular slag iron flue gas collecting function, which has the advantages of simple and reasonable structure and good use effect.
The technical solution of the utility model is as follows: the submerged arc furnace shell with the annular collecting slag iron smoke comprises a submerged arc furnace shell body, wherein the side surface of the submerged arc furnace shell body is provided with a tapping hole and a slag hole; the annular flue is provided with a pneumatic flap valve at the position of the iron outlet and the slag outlet; and an insulating flange butted with the dust removal pipeline is arranged on the side surface of the annular flue.
The section of the annular flue is rectangular.
The utility model has the advantages that: 1. Simple and reasonable structure, provides loose operation space for stokehold operation and is convenient for operation. 2. The pipeline installation is greatly reduced, the input cost is greatly reduced, and the manufacture, the installation, the maintenance and the overhaul are all easy. 3. The insulation point position is reduced, and the insulation reliability is enhanced.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic top view of the present invention.
Fig. 2 is a side view of the structure of fig. 1.
Detailed Description
Referring to fig. 1 and 2, the names of the components are as follows: the submerged arc furnace comprises a furnace shell 1 of the submerged arc furnace, an annular flue 2, a pneumatic flap valve 3, an insulating flange 4, a taphole 5, a slag outlet 6 and a dust removal pipeline 7.
Referring to fig. 1 and 2, the submerged arc furnace shell with the annular slag iron flue gas collecting function comprises a submerged arc furnace shell 1, wherein a tapping hole 5 and a slag hole 6 are formed in the side surface of the submerged arc furnace shell 1. An annular flue 2 with a rectangular cross section is fixed on the upper parts of a tap hole 5 and a slag hole 6 of the submerged arc furnace shell 1 and is welded with the submerged arc furnace shell 1 into a whole to support. The annular flue 2 is provided with pneumatic flap valves 3 at the positions of the iron outlet 5 and the slag outlet 6, and the pneumatic flap valves are used for correspondingly opening when one of the openings works so as to enable flue gas to enter the annular flue 2. The side surface of the annular flue 2 is provided with an insulating flange 4 butted with the dust removal pipeline 7, and the insulating flange has the function of insulating the dust removal pipeline, the annular pipeline and the furnace shell.
The working principle is as follows: when the submerged arc furnace works, generally one tapping hole 5 or one slag hole 6 works, when one of the holes starts to work, one pneumatic flap valve 3 corresponding to the annular flue 2 is opened (other three pneumatic flap valves 3 are closed), flue gas generated by the hole is collected and enters the annular flue 2, and the flue gas is sent into a dust removal pipeline 7 through an outlet of the annular flue 2 to enter a dust remover for flue gas purification treatment.
The foregoing description is only exemplary of the utility model and is not intended to limit the spirit of the utility model.
