On electrode bore dia it is generally bigger 100~200mm than electrode diameter, in heated by electrodes, especially when adding in raw material into ladle,
The a large amount of flue gases generated are escaped from this gap, and the environment and staff to surrounding cause very big pollution and injury.
Utility model content
The purpose of this utility model provides a kind of dust-extraction unit of furnace lid electrode hole, several are set around electrode hole
Nozzle sprays into gas through piping, air curtain is formed around electrode, flue gas is pressed into bell, prevents from escaping, eventually by
Dust-removing flue is taken away；Around reducing；The pollution of environment provides more clean working environment for staff.
The technical solution of the utility model is：A kind of dust-extraction unit of furnace lid electrode hole, it is characterized in that：There are three on bell
Electrode hole is provided with ring pipe around each electrode hole, several nozzles is fixedly connected on each ring pipe, and are distributed on
On ring pipe；Three ring pipes are interconnected two-by-two by branch pipe(tube)；Branch pipe(tube) by total pipeline successively with manually-operated gate, pneumatic
Valve, filter are connected with source of the gas.
The quantity of 7 top nozzle 8 of each ring pipe is 4~24, and injection center and the horizontal plane of nozzle 8 form angle
It is 45 °~75 ° to spend scope.
The total pipeline includes the total pipeline on total pipeline and platform on bell, total pipeline and platform on bell
On total pipeline between connected by hose.
The beneficial effects of the utility model are to set ring pipe in the circumferencial direction of each electrode hole, on ring pipe
Even several nozzles of installation, interconnect with ring pipe；Ring pipe is connected by pipeline with valve, filter, source of the gas, gas warp
Filter, flow ipe is sprayed through nozzle after valve opening, forms air curtain, and flue gas is pressed into bell, prevents from escaping, finally
It is taken away by dust-removing flue；Around reducing；The pollution of environment provides more clean working environment for staff.

Specific embodiment
Embodiment 1
A kind of dust-extraction unit of furnace lid electrode hole there are three electrode hole 10 on bell 9, is set around each electrode hole 10
There is ring pipe 7, several nozzles 8 are fixedly connected on each ring pipe 7, and are distributed on ring pipe 7；Three ring pipes 7 are logical
Branch pipe(tube) 5-1 is crossed to interconnect two-by-two；Branch pipe(tube) 5-1 by total pipeline 5 successively with manually-operated gate 4, operated pneumatic valve 3, filter 2
It is connected with source of the gas 1.
Embodiment 2
As shown in Figure 1, a kind of dust-extraction unit of furnace lid electrode hole, there are three electrode hole 10 on bell 9, in each electrode hole
Ring pipe 7 is provided with around 10, several nozzles 8 are fixedly connected on each ring pipe 7, and are distributed on ring pipe 7；Three
Ring pipe 7 is interconnected two-by-two by branch pipe(tube) 5-1；Branch pipe(tube) 5-1 by total pipeline 5 successively with manually-operated gate 4, operated pneumatic valve
3rd, filter 2 is connected with source of the gas 1；The total pipeline 5 includes the total pipeline on total pipeline and platform on bell 9, in bell 9
On total pipeline and platform on total pipeline between connected by hose 6.
Manually-operated gate adjusts required flow, and operated pneumatic valve needs to open according to dedusting, and gas flows into ring by filter
Shape pipe is sprayed through nozzle, forms air curtain, prevents flue gas from being escaped from gap.
Embodiment 3
As shown in Figure 1, bell 9 is uniformly distributed three electrode holes 10, an electrode 11 is inserted into each electrode hole 10, every
Ring pipe 7 around a electrode hole 10 is set, several nozzles 8 is fixedly connected on each ring pipe 7, and is distributed on ring pipe 7
On；Three ring pipes 7 are interconnected two-by-two by branch pipe(tube) 5-1, and then branch pipe(tube) 5-1 is connected with the total pipeline on bell 9, stove
Total pipeline on lid 9 is connected by hose 6 with the total pipeline on platform.The position that hose 6 can compensate for when bell 9 moves up and down becomes
Change, hose 6 is connected by the total pipeline on platform with manually-operated gate 4, operated pneumatic valve 3, filter 2 and source of the gas 1 successively.
Manually-operated gate 4 is according to its opening degree of required flow-rate adjustment, and when needing dedusting, operated pneumatic valve 3 is opened, source of the gas 1
By filter 2, through operated pneumatic valve 3, manually-operated gate 4, hose 6 enters three ring pipes 7, most sprays downwards, is formed through nozzle 8 afterwards
Air curtain.Flue gas is prevented to escape.
The nozzle centerline of nozzle 8 and horizontal plane shape be at 45 °~75 ° of angle, specific angle should be according to electrode hole 10
Gap between electrode 11 determines.When gap is bigger, the setting angle of nozzle 8 and the angle of horizontal plane are bigger.
The quantity of 7 top nozzle 8 of each ring pipe is 4~24, and particular number should be according to the big of electrode hole 10
Small to determine, the diameter of electrode hole 10 is bigger, and the quantity of nozzle 8 is accordingly more.
