Description
Technical field
The utility model relates to a kind of air curtain locking devices of high-temperature heater, for avoiding heating substance by air oxygen
Change.
Background technique
Currently, the fire door of high-temperature heater has been generally used sealing device, and is provided with air curtain and closes, these air curtains envelope
It closes simple use to spray closing by aperture or spray head with gas, so as to form air curtain, due to spraying from aperture or spray head
Gas can interfere with each other, partial region can be such that outside air enters in furnace instead sometimes, influence the quality of workpiece in furnace.
Utility model content
The purpose of this utility model is to provide a kind of air curtain locking devices, to improve the air exclusion of heating furnace inlet and outlet
Degree, specific technical solution are as follows:
A kind of air curtain locking device, including air-jet device and getter device;Wherein air-jet device includes cloth closed at both ends
Tracheae is connected with air inlet pipe and air nozzle, air nozzle length direction arrangement in long strip and along gas distribution pipe, spray on gas distribution pipe
Gas nozzle is provided with the slit of the inner cavity of connection gas distribution pipe, and slit is arranged along the length direction of gas distribution pipe;
The air intake duct that getter device includes vacuum plant, is connect with vacuum plant, closed at both ends, the air intake duct phase of air intake duct
Gas distribution pipe is arranged in parallel, the suction slot of the inner cavity of connection air intake duct is provided on air intake duct, suction slot is along air intake duct
The slit of length square arrangement, suction slot and air nozzle is positioned opposite.
It further, is control jet amount and saving gas consumption, the width of slit is 0.5-1.5mm.
To make gas reduce diffusing capacity, the width of slit and the ratio of depth are 1:5-1:8.
To be conducive to aspiration take in air curtain in air intake duct, the width of suction slot is 1-2 times of the width of slit.
Further, the side wall of suction slot is inclined outwardly, and making suction slot is in the shape of interior narrow outer width.Being inclined outwardly for side wall makes
The outlet of suction slot is capable of forming large-scale negative pressuren zone, is conducive to the absorption of air curtain gas.
When the utility model operation when, start vacuum plant, make the suction slot of air intake duct pair region formed negative pressuren zone,
The air curtain sprayed out of air nozzle slit is inhaled into air intake duct with gas, air nozzle continuously jet in air nozzle and air-breathing
Air curtain is formed between pipe.The single air nozzle with slit is used in the utility model, the gas of ejection will not interfere with each other,
And due to being siphoned away by air intake duct, the gas sprayed from air nozzle will not generate eddy-currents due to encountering the obstruction of surrounding, shadow
Ring the leakproofness of air curtain.
Detailed description of the invention
Fig. 1 is the schematic diagram of one embodiment of the utility model.
Fig. 2 be Fig. 1 in A-A to profile.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Please refer to Fig. 1 and Fig. 2, a kind of air curtain locking device, including air-jet device and getter device;Wherein air-jet device packet
Gas distribution pipe 5 closed at both ends is included, air inlet pipe 1 and air nozzle 6 are connected on gas distribution pipe 5, air nozzle 6 is in long strip and along gas distribution
The length direction of pipe 5 arranges that air nozzle 6 is provided with the slit 61 of the inner cavity 51 of connection gas distribution pipe 5, and slit 61 is along gas distribution pipe 5
Length direction arrangement;
Getter device includes the air intake duct 4 that vacuum plant 20, clearance pipeline 3 are connect with vacuum plant 20, and the two of air intake duct 4
End seal is closed, and air intake duct is arranged in parallel relative to gas distribution pipe 5, and the air-breathing of the inner cavity 42 of connection air intake duct is provided on air intake duct 4
Seam 41, for suction slot 41 along the length square arrangement of air intake duct 4, suction slot 41 and the slit 61 of air nozzle are positioned opposite.
The width L1 of slit is 0.5mm, and the depth H of slit is 2.5mm.The width of suction slot L2 is 1mm.
In the present embodiment, the side wall of suction slot is inclined outwardly, and making suction slot is in the shape of interior narrow outer width.
The width L1 of above-mentioned slit, which is set as 1-1.5mm, to be advisable, and the width of slit and the ratio of depth are between 1:5-1:8
Preferably.The width of suction slot is that 1-2 times of the width of slit is advisable.
When the utility model operation when, start vacuum plant, make the suction slot of air intake duct pair region formed negative pressuren zone,
The air curtain gas 10 sprayed out of air nozzle slit is inhaled into air intake duct, and air nozzle continuously in air nozzle and inhale by jet
Air curtain is formed between tracheae.The single air nozzle with slit is used in the utility model, the gas of ejection will not mutually be done
It disturbs, and due to being siphoned away by air intake duct, the gas sprayed from air nozzle will not generate eddy-currents due to encountering the obstruction of surrounding,
Influence the leakproofness of air curtain.
