Description
Technical field
Provided by the utility model is the heat preservation of metal smelting-furnace crest of weir chute and smoke collecting device that field of metallurgy uses.
Background technique
The high-temperature fusant that existing smelting furnace generates is flowed out from crest of weir overflow, is entered sedimentation electric furnace by crest of weir chute and is sunk
Drop separation, since chute is longer, when high-temperature fusant passes through crest of weir chute, heat is largely lost, the melt heat insulation effect in chute
Bad, clinker and molten mixture cause the excessive of blend melt easily in the cooling blocking chute in chute two sides.Meanwhile high temperature
Melt contacts when passing through crest of weir chute with air, generates a large amount of flue gas, and flue gas is more dispersed, is not easy to be enriched with, and deteriorates live ring
Border.There is producer to use straw or rock wool board for the heat preservation of crest of weir chute, also have and covered on crest of weir chute using muti-piece iron plate, but protects
Temp effect is all bad, and leakproofness is poor, and flue gas is easy excessive, while service life is short, frequently replaces, production cost is caused to rise.
Utility model content
In order to overcome heat insulation effect existing for existing metal smelting-furnace crest of weir chute bad, leakproofness is poor, and flue gas is easy outer
Excessive disadvantage, the utility model provide the heat preservation of metal smelting-furnace crest of weir chute and smoke collecting device.The heat preservation and smoke collecting device are logical
Setting removable cover, cover board inside holding are crossed, crest of weir uses top air inducing, chute side air inducing, chute and holding furnace junction top
Air inducing, each air inducing pipeline installation butterfly valve adjust draft, solve chute heat preservation and the excessive technical problem of flue gas.
The utility model solves scheme used by technical problem:
It is equipped with crest of weir in metal smelting-furnace lower part side, for the outflow of melt, is bathtub construction, weir is housed on crest of weir
Mouth enclosure, is connected with crest of weir smoke discharging pipe on crest of weir enclosure, is connected between crest of weir lower part and sedimentation electric furnace top
Chute, sedimentation electric furnace and chute junction are equipped with exhaust fume collecting hood, flue are connected on exhaust fume collecting hood, the side of chute is connected with
Chute smoke discharging pipe is stamped heat-preserving cover plate on chute top.
Heat-preserving cover plate side is provided with hook, and drawstring is connected on hook, and drawstring determines cunning by being arranged on bracket
Wheel is connected with weight；The crest of weir smoke discharging pipe, chute smoke discharging pipe and flue are pooled to main line and are connected with air-introduced machine.
Good effect is connected with crest of weir smoke exhaust pipe since the utility model is equipped with crest of weir enclosure above crest of weir thereon
Road, and chute smoke discharging pipe is also connected in chute, while also being provided with flue in chute and sedimentation electric furnace junction, institute
It can timely and effectively be drawn with the flue gas generated when melt passes through chute.Heat-preserving cover plate is stamped on chute, it can be to slipping
Melt in slot is kept the temperature, and heat radiation and heat convection are reduced.Therefore compared with existing chute cover board, there is superior performance
With practical advantage.It is suitable for being used as the heat preservation of metal smelting-furnace crest of weir chute with smoke collecting device.
Detailed description of the invention
Fig. 1 is the utility model structure chart；
In figure, 1. metal smelting-furnaces, 2. sedimentation electric furnaces, 2.1. exhaust fume collecting hood, 3. crest of weir enclosures, 4. chutes, 5. insulation covers
Plate, 6. brackets, 7. fixed pulleys, 8. drawstrings, 9. weights, 10. crest of weir smoke discharging pipes, 11. chute smoke discharging pipes, 12. fume pipes
Road, 2.1. exhaust fume collecting hood, 13. air-introduced machines.
Specific embodiment
According to the figure, it is equipped with crest of weir in 1 lower part side of metal smelting-furnace, is bathtub construction, on weir for the outflow of melt
Crest of weir enclosure 3 is housed on mouth, crest of weir smoke discharging pipe 10 is connected on crest of weir enclosure, in crest of weir lower part and sedimentation electric furnace 2
Chute 4 is connected between top, sedimentation electric furnace and chute junction are equipped with exhaust fume collecting hood 2.1, fume pipe are connected on exhaust fume collecting hood
Road 12, the side of chute are connected with chute smoke discharging pipe 11, are stamped heat-preserving cover plate 5 on chute top.
Heat-preserving cover plate side is provided with hook, is connected with drawstring 8 on hook, drawstring determining on the frame 6 by setting
Pulley 7 is connected with weight 9；The crest of weir smoke discharging pipe, chute smoke discharging pipe and flue are pooled to main line and air-introduced machine
13 are connected.
The heat-preserving cover plate is equipped with insulating layer.
The chute insulation cover subsection setup, convenient for raising.
It is respectively arranged with butterfly valve on the crest of weir smoke discharging pipe and chute smoke discharging pipe and flue, for adjusting smoke evacuation
Amount.
The course of work:
The melt of metal smelting-furnace output is flowed into sedimentation electric furnace by crest of weir and chute and carries out Gravity Separation.
When needing to open heat-preserving cover plate, heat-preserving cover plate is opened using manpower by fixed pulley, the use of weight can subtract
The small aperture exerted oneself and keep cover board.
When needing to discharge fume to crest of weir and chute, then the butterfly valve on each pipeline is opened, is discharged fume using air-introduced machine.
Feature:
Compared with existing chute, due to being equipped with smoke discharging pipe in crest of weir, chute and sedimentation electric furnace junction, so can
The flue gas that high-temperature fusant generates is discharged, guarantees that crest of weir, chute, chute and the flue gas of holding furnace junction be not excessive, flue gas is made to converge
Collection is discharged by air-introduced machine, protects environment.
Due to being stamped heat-preserving cover plate on chute top, so can keep the temperature to by the melt of chute, temperature is prevented
Decline it is too fast cause molten mixture in the cooling blocking chute in chute two sides, cause the excessive of blend melt.
Due to being provided with chute heat preservation lid support and fixed pulley in chute side, is conducive to start by drawstring and closing is slipped
Slot insulation cover facilitates the opening and closing of chute insulation cover.
Due to being equipped with butterfly valve on flue, so flue gas discharge rate can be controlled, air introduction volume is reduced.
