Abstract
A sealing device for a spraying muzzle of a top-blown foundering melting furnace is provided. The utility model pertains to a supplementary unit for the top-blown foundering melting furnace, in particular to a sealing device for the spraying muzzle. The utility model adds a dust collection cover around the spraying muzzle and the dust collection cover is connected with a flue gas discharge port by means of a dust collector and an exhaust fan sequentially so as to gather and dispose of flue gas and powder from the spraying muzzle. As a result, the goal of environmental conservation and powder colletion can be attained. The utility model has the advantages of simple structure and easy operation. The device inhales flue gas and powder dissipating from the spraying muzzle into the dust collecting system through negative pressure for gathering and disposing of flue gas and powder and it resolves the problem of no sealing device existing in the primary spraying muzzle of a top-blown foundering melting furnace.
Description
Technical field
The utility model belongs to the tightness system of the accessory device on the top-blown submergence smelting furnace, particularly gun slot.
Background technology
The top-blown submergence smelting technique is also referred to as top-blown submergence spray gun smelting technique (top submerged lancetechnology).It is the non-ferrous metal intensified smelting technology of being succeeded in developing on match sieve smelting technique (SirosmeltTechnology) basis by Australian Australia Si Maite company.Its primary process is with a spray gun through particular design, among the melt in the round tube type burner hearth of furnace roof insertion fixed vertical placement, air and fuel directly spray into the melt from the spray gun end, form the molten bath of acutely seething in stove, and furnace charge directly drops into molten bath in the stove by the top filling mouth.
When Australia furnaceman Si Maite of routine does, for reducing atmosphere preferably in the control molten bath, need have suitable furnace inner gas pressure, the result must have a certain amount of melting flue gas and overflow around gun slot, causes the loss of environmental pollution and valuable metal.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of top-blown submergence smelting furnace gun slot tightness system, and it is simple in structure, can prevent that the melting flue gas is excessive, avoids environmental pollution, reclaims valuable metal.
Solving the scheme that technical problem of the present utility model adopts is: adorned a draught hood at the gun slot place, draught hood is communicated with the clean flue gas discharge outlet by dust-precipitator, vacuum fan successively, and spray gun passes the draught hood jacking and goes in the Australia Si Maite stove.
By the above-mentioned a series of devices that around gun slot, are provided with, vacuum fan can produce negative pressure at the gun slot place, after flue gas and dust enter dust-precipitator from pipeline, can carry out effective collection and clean the processing to the valuable metal in flue gas and the dust, produce the phenomenon of polluting thereby eliminated traditional Australia Si Maite stove gun slot place; The valuable metal of collecting in the dust-precipitator is used again, has avoided the loss of valuable metal.
The utility model has overcome the problem and shortage that exists in the top blow sinking smelting process, has the following advantages:
(1) will carry out effective collection and clean the processing from excessive flue gas and the dust that comes that shed of gun slot, realize the sealing of gun slot, solve problem of environmental pollution.
(2) tightness system is convenient to operation, does not influence the normal use of spray gun.
(3) can reclaim the flue dust that overflows and shed and from gun slot effectively, improve the rate of recovery of metal.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented successively among the figure: gun slot 1, flue gas 2, movable draught hood 3, rotation stand 3a, spray gun 4, support 5, bagroom 6, vacuum fan 7, clean flue gas discharge outlet 8, spray gun sleeve 9, Australia Si Maite stove burner hearth 10, sleeve wind outlet 11, molten bath 12, spray gun wind outlet 13, Australia Si Maite stove 14, hinged door 15
Embodiment
Referring to Fig. 1, the structure of this tightness system is: adorned a movable draught hood 3 at gun slot 1 place, movable draught hood 3 is communicated with clean flue gas discharge outlet 8 by bagroom 6, vacuum fan 7 successively, and spray gun 4 passes movable draught hood 3 jackings and goes in the Australia Si Maite stove 14.For the ease of spray gun 4 being shifted out the operation of Australia Si Maite stove 14, movable draught hood 3 is contained on the support 5 of band rotating shaft, and the sidewall of movable draught hood 3 is equipped with hinged door 15, as long as hinged door 15 is opened, swinging mounting 5 just can make movable draught hood 3 move out.
During work, start vacuum fan 7 and produce negative pressure, be housed in gun slot 1 and spray gun 4 movable draught hood 3 collection extractions on every side from the gun slot 1 excessive flue gas 2 that sheds, enter bagroom 6, with after the entrained filtrating smoke dust collection, clean flue gas is extracted out through vacuum fan 7 again in bagroom 6, from 8 dischargings of clean flue gas discharge outlet, realize the sealing of gun slot, solved the purpose of problem of environmental pollution.Spray gun 4 need be opened the hinged door 15 on the movable draught hood 3 when gun slot 2 shifts out Australia Si Maite stove 14, and movable draught hood 3 goes to rotation stand 3a along support 5, just spray gun 4 can be proposed.After spray gun 4 inserts gun slots 1, movable draught hood 3 from rotation stand 3a, is threaded to original position along support 5, and the hinged door of buckling well on the movable draught hood 3 15 shuts, but just normal operation.
Claims (3)
1, a kind of top-blown submergence smelting furnace gun slot tightness system is characterized in that: adorned a draught hood at the gun slot place, draught hood is communicated with the clean flue gas discharge outlet by dust-precipitator, vacuum fan successively, and spray gun passes the draught hood jacking and goes in the Australia Si Maite stove.
2, top-blown submergence smelting furnace gun slot tightness system according to claim 1 is characterized in that: draught hood is contained on the support of band rotating shaft, and the sidewall of draught hood is equipped with hinged door.
3, top-blown submergence smelting furnace gun slot tightness system according to claim 1 is characterized in that: what dust-precipitator adopted is bagroom.
