Description
Technical Field
The utility model belongs to the nickel field of smelting, concretely relates to top-blown smelting furnace spray gun mouth sealing device.
Background
The top-blown converter adopts an oxygen-rich nickel smelting process, and the technological process of the system adopts an oxygen-rich top-blown submerged lance molten pool smelting-P-S converting process. The flow is that after various concentrates are mixed and granulated, flux and limestone are mixed and enter a top-blown furnace through a feeding system. The fuel, wind and oxygen required in the smelting process are supplied by the spray gun, and generate physical and chemical reaction under the stirring action of the airflow of the spray gun, so that the enrichment of valuable metal sulfides and the separation of slag are realized. Therefore, the top-blown converter spray gun is the core of the top-blown converter smelting process, and the spray gun is inserted into the top-blown converter through a spray gun port at the top of the converter and invades into a molten pool. However, because the reaction in the furnace is violent and the pressure is high, flame, splashed objects and partial high-temperature smoke are sprayed out from the inlet of the spray gun, so that the surrounding environment is polluted and the life safety of surrounding workers is threatened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem existing in the prior art, providing a top-blowing type smelting furnace spray gun mouth sealing device with simple structure and capable of blocking splashes and high-temperature flue gas.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a top-blown smelting furnace spray gun mouth sealing device, includes the ring flange, the conical duct is connected to the ring flange, and the spray gun is passed by conical duct inside, conical duct top is equipped with sealed round platform, the sealed round platform outside is equipped with sealed round shell, sealed round platform, sealed round shell and spray gun form the seal groove, the sealing material is filled in the seal groove, sealed round shell outside is equipped with the lug, the lug passes through anchor chain and is connected with welded rings on the spray gun, the anchor chain bottom is equipped with the system and moves back the hook, the system moves back the hook and is connected with the lug through breaking out.
The inner diameter of the flange plate is the same as the diameter of the spray gun opening.
The utility model discloses relative prior art has following beneficial effect: the utility model discloses sealing device is through setting up the pressure of conical tube buffering high temperature splash thing, and the sealing material of intussuseption through conical tube top seal groove intussuseption can seal flame, splash thing and high temperature flue gas, has avoided the flue gas to scald staff's potential safety hazard to the pollution of surrounding environment and high temperature splash thing. The utility model discloses simple structure, practicality are strong, have fine application prospect and use value.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the method comprises the following steps of 1-flange plate, 2-conical pipe, 3-spray gun, 4-sealing circular table, 5-sealing circular shell, 6-sealing groove, 7-lifting lug, 8-anchor chain, 9-lifting ring and 10-made withdrawing hook.
Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
As shown in figure 1, a for top-blowing smelting furnace spray gun mouth sealing device, including ring flange 1, ring flange 1 connects conical tube 2, spray gun 3 is passed by conical tube 2 is inside, ring flange 1 internal diameter is the same with spray gun mouth diameter, 2 tops of conical tube are equipped with sealed round platform 4, the sealed round platform 4 outside is equipped with sealed round shell 5, sealed round platform 4, sealed round shell 5 forms seal groove 6 with spray gun 3, the packing material is filled in seal groove 6, the sealing material is the asbestos felt, sealed round shell 5 outside is equipped with lug 7, lug 7 is connected through anchor chain 8 and welded rings 9 on the spray gun 3, 8 bottoms of anchor chain are equipped with and make and move back hook 10, make and move back hook 10 and be connected with lug 7 through breaking out.
Demolish system when the converting position is transferred to spray gun 3 and move back hook 10 and make spray gun sealing device steadily fall on the spray gun mouth entrance at smelting furnace roof, when flame, splash thing and partial high temperature flue gas spout from the spray gun entrance, the pressure that can cushion high temperature splash thing is set up to the toper structure of this sealing device conical tube 2, the sealing material of intussuseption in conical tube top seal groove 6 can be sealed flame, splash thing and high temperature flue gas, avoided the flue gas to the pollution of surrounding environment and high temperature splash thing scald staff's potential safety hazard.
