Abstract
The utility model provides a metallurgical furnace siphoning deslagging device which comprises lining bricks which are attached to a furnace wall of a metallurgical furnace in an embedded mode. Fireproofing materials are arranged on the outer sides of the lining bricks, siphoning channels are arranged on the lining bricks and the fireproofing materials. Each siphoning channel is composed of a siphoning opening, a siphoning molten bath and a siphoning cornice, wherein the siphoning opening is communicated with the metallurgical furnace, and the position of the siphoning cornice is higher than the position of the siphoning opening. In the metallurgical furnace siphoning deslagging device, a siphon principle is effectively used for deslag, slags on the inner surface of the metallurgical furnace can be controlled not to be removed, unseparated slags, non-settling valuable metal and beneficial components on the inner surface of the metallurgical furnace are guaranteed to be not easy to remove outside the metallurgical furnace, and economic indicators are optimized.
Description
Technical field
The utility model belongs to technical field of non-ferrous metallurgy, relates to a kind of metallurgical furnace slag tapping equipment, is specifically related to a kind of metallurgical furnace siphon deslagging device that is applicable to the heavy non-ferrous metal slag emissions such as copper, lead, zinc, nickel.
Background technology
At present, heavy non-ferrous metallurgy field at home and abroad, the discharging of metallurgical furnace slag is general to be adopted interrupted or continuous blow-down is surface discharge and middle level discharging, intermittently discharges such as the continuous blow-down of Flash Smelting Furnace slag, electric-furnace slag.Wherein, the characteristics of continuous blow-down slag are: the quantity of slag is stablized easy to control, but the unclarified valuable metal of stove inner surface and the useful composition that does not melt also discharge with slag, strengthened valuable metal loss, reduced the utilization rate of beneficiating ingredient.The characteristics of interrupted discharging slag are: slag emission is unstable, and when the melt face was high in the stove, the discharging quantity of slag was larger, and there is potential safety hazard in discharging; Slag emission is when the melt face is concordant with cinder notch to the later stage, the stove inner surface do not clarify valuable metal and the useful composition that does not melt is also discharged with slag, strengthened equally valuable metal loss, reduced the utilization rate of beneficiating ingredient.Therefore existing slag emission technology all exists and does not clarify valuable metal and the useful composition that does not melt easily with slag is discharged, the valuable metal loss is high problem.
The utility model content
The purpose of this utility model is to provide a kind of stove inner surface not separate the metallurgical furnace siphon deslagging device that slag, unclarified valuable metal and beneficiating ingredient are difficult for discharging out of the furnace for the problem of prior art existence.
For this reason, the utility model adopts following technical scheme:
A kind of metallurgical furnace siphon deslagging device comprises the lining brick that the furnace wall embedding of applying metallurgical furnace is built, and the described lining brick outside is provided with refractory material, offers the siphon passage that connects on described lining brick and the refractory material; Described siphon passage is made of siphon port, siphon molten bath and siphon cornice, and described siphon port is connected with metallurgical furnace, and the position of described siphon cornice is higher than the position of siphon port.
Be provided with the lining brick water jacket between described lining brick and the refractory material.
Described refractory material is coated with the refractory material water jacket.
Described siphon cornice is coated with the cornice water jacket.
Top, described siphon molten bath has opening and opening part is provided with cover plate.
The beneficial effects of the utility model are:
(1) effectively utilizes siphon principle to carry out deslagging, can control all the time stove inner surface slag and not be excluded, guarantee that the stove inner surface does not separate slag, unclarified valuable metal and beneficiating ingredient and is difficult for discharging out of the furnace, optimized economic indicator;
(2) adopt siphon slagging technology, strengthened the performance of metallurgical furnace slag continuous blow-down;
(3) can realize that instantaneous bed drain purge is controlled, can because of the excessive damage follow-up equipment of quantity of slag facility, not improve the security of tapping process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of metallurgical furnace siphon deslagging device comprises the lining brick 3 that the furnace wall embedding of applying metallurgical furnace is built, and lining brick 3 peripheral side are provided with refractory material 8, offers the siphon passage that connects on lining brick 3 and the refractory material 8; Siphon passage is made of siphon port 2, siphon molten bath 1 and siphon cornice 6, and wherein, siphon port 2 is connected with metallurgical furnace, and the position of siphon cornice 6 is higher than the position of siphon port 2.Be provided with lining brick water jacket 4 between lining brick 3 and the refractory material 8; Refractory material 8 is coated with refractory material water jacket 9; Siphon cornice 6 is coated with cornice water jacket 7.1 top, siphon molten bath has opening and opening part, and to be provided with cover plate 5(opening not shown).
During slagging, the slag system material constantly raises with the liquid level that carries out of smelting process in the stove, when arriving siphon port 2 height, liquid slag enters siphon molten bath 1, liquid level continues to raise, be full of siphon molten bath 1 until siphon cornice 6, when the liquid slag height surpassed siphon cornice 6, liquid slag was by 6 outflows of siphon cornice.When slag when variation appears in siphon cornice 6, namely finish the discharge process of slag.
