Embodiment 1

[0018] like figure 1 and figure 2 As shown, the conical fume hood mechanism of this titanium slag furnace includes the main beam composed of the outer cone 1 and the inner cone 2. The welding seam of the main beam is reduced, the inner cone 2 is located above the outer cone 1, and the diameter of the inner cone 2 is smaller than the diameter of the outer cone 1, and there are several auxiliary beams 9 between the outer cone 1 and the inner cone 2 The connection is fixed, the gap formed between the main beam and the sub-beam 9 is fixed with a cover plate 4, and the outside of the outer cone 1 is also connected with a dust suppression box 3, thus forming a conical smoke hood structure, and all the sub-beams 9 are It is the butt joint of the whole seamless steel pipe, and all welds are under pressure, thus realizing a seamless skeleton and changing the original historical pattern of channel steel butt joint, polygonal splicing, large weld seam volume and easy cracking.

Embodiment 2

[0024] The inner side of the inner cone circle 2 is ring-connected with a triangular frame 5 , and inside the triangular frame 5 is a polar center circle area 6 , which is reserved for electrode holes 7 and feeding holes 8 on the cover plate 4 .

[0025] Each side of the triangular frame 5 is fixedly connected to the adjacent points of the inner cone circle 2 through several sub-beams 9, and the gap between the triangular frame 5 and the inner cone circle 2 is also fixed with a cover plate 4, thereby increasing the strength of the triangular frame 5. Stability, in this embodiment, three sub-beams 9 connected with the inner cone circle 2 are uniformly fixed on each side.

[0026] Three electrode holes 7 of the same specification are distributed symmetrically in a triangular shape in the triangular frame 5, and the three graphite electrodes are respectively extended from the three electrode holes 7 to the titanium slag furnace. There are several blanking holes 8 on the blank cov...

Embodiment 3

[0028] There are two floor-standing water-cooled dust suppression boxes 3 arranged symmetrically on the outside of the outer cone 1, and the upper part of the dust suppression box 3 is a flue. These two dust suppression boxes 3 can directly absorb 60% of the flue gas temperature in the titanium slag furnace flue gas, and improve the temperature of the dust collector. The service life of the cloth bag is more than 3 times. Because it is located in the symmetrical position on both sides of the outer cone 1, the rolling smoke cloud formed with the conical furnace cover can just be sucked away, just like the suction port of a tornado. Put an end to the unorganized emission of smoke, and fundamentally solve the unfavorable historical situation of smoke pollution in the workshop.

[0029] The large particle attachments in the flue can be discharged into the dust suppression box 3 in an organized manner, and there is no possibility of polluting the production environment, which effect...

Abstract

The invention relates to a conical hood mechanism of a titanium slag furnace, which at least comprises a main beam, wherein the main beam is formed by an outer conical circle and an inner conical circle. The conical hood mechanism is characterized in that the inner conical circle is positioned above the outer conical circle, and the diameter of the inner conical circle is less than that of the outer conical circle; the outer conical circle and the inner conical circle are fixedly connected through a plurality of secondary beams; cover plates are arranged in void positions formed between the main beam and the secondary beams; and the outer side of the outer conical circle is connected with a dust box. According to the conical hood mechanism disclosed by the invention, ascending fume in the furnace is spirally moved to form spout fume cloud, the fume in the furnace is circularly moved in a hood faster and faster, so that the self forming force of the fume is increased, the fume is moved in an organized way, and the possibility of discharge and diffusion in an unorganized way cannot occur; additionally, a molten pool in the furnace can be effectively prevented from irradiating a body of the hood is effectively prevented from being irradiated by the high temperature due to high temperature and heat radiation in a molten pool by the thick spout fume cloud, so that the heat absorption capacity of high molecular jointing materials is reduced, and the high molecular jointing materials are prevented from cracking caused by large change of temperature difference and shedding caused by cripling; and the circulating water temperature of the cover plates of the hood is effectively reduced.

Description

technical field [0001] The invention relates to the field of titanium slag furnaces, in particular to a conical fume hood mechanism for titanium slag furnaces. Background technique [0002] Titanium slag furnace is a large-scale equipment for smelting titanium concentrate powder. The existing titanium slag electric furnaces are all developed on the basis of ferroalloy electric furnaces. Ferroalloy electric furnaces mostly produce oxide ores. For the yield of alloys, the high-temperature parts of the smelting work must be sealed, and open arc smelting should not occur for a long time to cause a large amount of high-temperature volatilization of ores and reduce the yield of elements. It is necessary to create a closed high-temperature dry pot reducing environment for oxide ores. For smelting, the strength and length of the electrode arc should not be too large, so that the oxide ore can reduce volatilization and have a better element yield, so the current-voltage ratio is set ...
