Abstract
The utility model discloses a flame sealing device for a discharging hole of a non-muffle mesh-belt furnace. The flame sealing device comprises a flame spraying pipe, wherein the flame spraying pipe is a hollow round pipe; sand is put inside the flame spraying pipe; a row of drainage nozzles communicated with a core of the flame spraying pipe are uniformly distributed at the axial periphery of the flame spraying pipe; one end of the flame spraying pipe is connected with a hollow bamboo tube; the bamboo tube is connected with a rubber pipe leaded by an air source through an adjustment valve; a step shaft is fixed blocked at the other end of the flame spraying pipe. According to the flame sealing device, the drainage nozzles are mounted, so that the sprayed flame is straightly dense and uniform; the discharging hole of the non-muffle mesh-belt furnace is selected to be subjected to enhancing sealing, and the sealing device can rotate and plays a good sealing roll, so that the quality of a quenching workpiece is obviously improved; the sand is put in the flame spraying pipe, so that the pressure inside the pipe is effectively adjusted, and the sprayed flame is uniform. After being detected in use, a decarburized layer after the workpiece is quenched is obviously reduced, the surface quality of the workpiece is obviously improved, and a crack phenomenon on the workpiece after being quenched is avoided.
Description
Technical field
The utility model relates to a kind of without horse meshbeltfurnace furnace mouth seal device not, especially a kind of for without the horse flame sealing device of fire door under meshbeltfurnace not.
Background technology
Without horse not the shortcoming of meshbeltfurnace maximum be exactly that sealing is poor.The sealing of its lower fire door backward channel only depends on the jam-pack of rockwool blocks can not deal with problems completely.Because guipure ceaselessly moves back and forth, tend to cause loosening, the slippage of rockwool blocks, thereby produce gap, cause workpiece oxidation and decarbonization.
Summary of the invention
The purpose of this utility model is to provide a kind of without horse fire door flame sealing device under meshbeltfurnace not, improves without the horse sealing of meshbeltfurnace not, thereby reduces workpiece oxidation and decarbonization, improves workpiece surface quality, avoids the generation of workpiece crack.
The purpose of this utility model realizes as follows: comprise a flame jet pipe, flame jet pipe is the circular pipe of a hollow, in flame jet pipe, sand is housed, along the drainage nozzles that is uniform-distribution with a row in flame jet pipe axial periphery and communicates with the die of flame jet pipe, flame jet pipe one end connects the ring pipe of hollow, the rubber tube that ring pipe is drawn with source of the gas by control valve is connected, and the other end of flame jet pipe is Step Shaft of shutoff fixedly.
The in-built appropriate sand of flame jet pipe, with the husky amount of dress number can regulate the size of flame jet pipe internal pressure to make the flame of ejection close and even.The two ends of flame jet pipe are supported on two supports by Step Shaft and ring pipe, and support is fixed on body of heater, and flame jet pipe can be rotated on support, so that the angle of nozzle can regulate.Control valve is for adjusting the size of flame.
On the connecting line of ring pipe and control valve, be connected to check-valves, to guarantee its security.
The utility model design and installation drainage nozzles, makes the flame of ejection directly close, even; Be chosen in without horse not the lower fire door of meshbeltfurnace carry out enhanced leaktightness, and sealing device can rotate, and played good sealing effectiveness, and quenching part quality is obviously improved; At the in-built sand of flame jet pipe, effectively regulated overpressure, make the flame of ejection more even.Through using, detect, after workpiece quenching, decarburized layer obviously reduces, and workpiece surface quality obviously improves, and does not find seminess after workpiece quenching.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, there is a flame jet pipe 1, flame jet pipe 1 is the circular pipe of a hollow, sand 6 is housed in flame jet pipe 1, along being uniform-distribution with the drainage nozzles 2 that a row communicates with die in flame jet pipe 1 axial periphery, drainage nozzles 2 is the circular short tube of a hollow, and drainage nozzles 2 plays the effect of drainage orientation, make the flame of ejection can reach predetermined height, and directly close, even; Flame jet pipe 1 one end connects the ring pipe 3 of hollow, and the rubber tube that ring pipe 3 is drawn with source of the gas by control valve 5 is connected, and on the connecting line of ring pipe 3 and control valve 5, is connected to check-valves 4, and the other end of flame jet pipe 1 is Step Shaft of shutoff fixedly.Flame jet pipe 1 is supported on the support on lower fire door both sides by Step Shaft and ring pipe 3, and flame jet pipe 1 can be rotated relative to support, to regulate the direction of drainage nozzles 2, makes the flame of drainage nozzles 2 ejections can seal well lower fire door.Control valve 5 is controlled flame size in order to adjusting gas flow.Sand 6 is evenly distributed in the bottom of flame jet pipe 1 substantially, play the auxiliary effect of controlling flame jet pipe 1 interior gas pressure, prevent that the gas entering from ring pipe 3 is trapped in the interior one end near ring pipe 3 of flame jet pipe 1, or excessive and can not arrive smoothly the other end of flame jet pipe 1 from the amount near the 3 one end ejections of ring pipe, pack into after sand 6, can make the flame of drainage nozzles 2 ejections substantially even.
