Description
Technical field
It is especially a kind of for double flap valve controls the utility model relates to metal melt smelting equipment manufacturing technology field
Elephant trunk blanking sealing device processed.
Background technique
Emission of baiting chute is the key component of pneumatic steelmaking blanking system, and various furnace charges converge after hopper weighs from branch's elephant trunk
Collect and summarize storehouse, is then entered in furnace by emission of baiting chute.In addition to undertaking conveying furnace charge effect, emission of baiting chute latter end position is main
Effect is that the flue gas and dust emitted up in steelmaking process is sealed using nitrogen, to guarantee dust removing effects and coal-gas recovering amount.
Original nitrogen-sealed pipe outlet is mounted on elephant trunk least significant end, and the cutting-off valve and converter oxygen gun operation for controlling nitrogen interlock, whole
The time of a switch nitrogen and flow control are unreasonable, cause nitrogen consumption excessive, and coal-gas recovering amount is not high.Disappear from the energy
From the point of view of consumption and coal-gas recovering use aspects, the sealing means and interlock method of emission of baiting chute latter end play the role of vital.
Current emission of baiting chute nitrogen-sealed mode not only causes a large amount of wastes of the energy, and blanking system equipment exists because explosion is damaged
Hidden danger, and smolder and cause very big influence to production environment.
Utility model content
The problems solved by the utility model are to provide a kind of double flap valve control elephant trunk blanking sealing devices, solve existing
Emission of baiting chute nitrogen-sealed mode effect difference causes energy waste and there are problems that security risk.
To solve the above-mentioned problems, the technical solution adopted in the utility model is: this double flap valves control elephant trunk blanking
Sealing device includes being mounted on emission of baiting chute and being equipped with the pneumatic of flap to turn over plate valve and the pneumatic lower turnover panel equipped with lower turnover panel
Valve, the plate valve that pneumatically turns over are equipped with cylinder for controlling the flap and the lower turnover panel, the cylinder with it is described
Flap is connected with the lower turnover panel by connecting rod, and described pneumatically turn over is additionally provided with nitrogen between plate valve and the pneumatic lower turnover panel valve
Device is sealed, the nitrogen envelope device is equipped with nitrogen tube sealing, and the nitrogen tube sealing protrudes into inside the nitrogen envelope device, forms circumferential sealing.
In above-mentioned technical proposal, more specific technical solution may also is that middle section and institute of the cylinder by upper connecting rod
Flap to be stated to carry out hingedly, one end of the upper connecting rod is hinged with middle connecting rod, and the other end of the middle connecting rod is hinged with lower link,
The other end of the lower link is hinged with the lower turnover panel.
By adopting the above-described technical solution, the utility model has had the following beneficial effects: furnace compared with prior art
When material falls, cylinder controls flap and lower turnover panel is opened, while nitrogen tube sealing gas source is opened, by the flue gas and dust of smelting process
It is sealed by the nitrogen that nitrogen seals device；Furnace charge stops lower backwardness, and cylinder controls flap and lower turnover panel is closed, while nitrogen tube sealing gas source
It closes, seals flue gas and dust by flap and lower turnover panel, to reach entire smelting process sealing effect, nitrogen is greatly lowered
Consumption improves coal-gas recovering amount；The start-stop of furnace charge and Telescopic-cylinder, the interlocking of nitrogen tube sealing gas source switch are got up, realize automatic control
System；Cylinder can control the synchronous operation of Dual-layer turnover panel, and the gas source pipe in the middle part of nitrogen envelope device enters inside nitrogen envelope device, form encircling type
Sealing, improves the sealing effect of emission of baiting chute.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram for pneumatically turning over plate valve.
Fig. 3 is the structural schematic diagram of pneumatic lower turnover panel valve.
Fig. 4 is the structural schematic diagram of nitrogen envelope device.
Specific embodiment
The utility model is described in further detail for example with reference to the accompanying drawing:
Double flap valves as shown in Figure 1, Figure 2, Figure 3 and Figure 4 control elephant trunk blanking sealing device, including are equipped with flap 1-
1 pneumatically turns over plate valve 1 and the pneumatic lower turnover panel valve 2 equipped with lower turnover panel 2-1, pneumatically turns over plate valve 1 equipped with cylinder 4, cylinder 4
It is connected with flap 1-1 and lower turnover panel 2-1；It pneumatically turns over and is additionally provided with nitrogen envelope device 3, nitrogen envelope between plate valve 1 and pneumatic lower turnover panel valve 2
Device 3 is equipped with nitrogen tube sealing 3-1；Cylinder 4 is carried out hingedly by the middle section of upper connecting rod 4-1 and flap 1-1, and the one of upper connecting rod 4-1
End is hinged with middle connecting rod 4-3, and the other end of middle connecting rod 4-3 is hinged with lower link 4-2, the other end and lower turnover panel of lower link 4-2
2-1 is hinged.
In use, cylinder 4 is opened simultaneously with nitrogen tube sealing 3-1, and cylinder 4 passes through upper connecting rod 4-1 when opening furnace charge whereabouts switch
It controls flap 1-1 to open, connecting rod 4-3, middle connecting rod 4-3 drive lower turnover panel 2-1 to open in upper connecting rod 4-1 drive, and furnace charge is under
Material elephant trunk 5 successively enters in furnace by pneumatically turning over plate valve 1, nitrogen envelope device 3 and pneumatic lower turnover panel valve 2, by opening nitrogen tube sealing 3-1
Effect be to be sealed the flue gas and dust that smelting process is emerged using nitrogen；After closing furnace charge whereabouts switch, cylinder 4 and nitrogen are sealed
Pipe 3-1 is simultaneously closed off, and cylinder 4 controls flap 1-1 by upper connecting rod 4-1 and closes, connecting rod 4-3 in upper connecting rod 4-1 drive, middle company
Bar 4-3 drives lower turnover panel 2-1 to close, and seals flue gas and dust by flap 1-1 and lower turnover panel 2-1.To improve entire smelt
Procedure seals effect is greatly lowered nitrogen consumption, improves coal-gas recovering amount.
