[0035] Example

[0036] A drainage mist device for online quenching equipment for aluminum materials comprises a mesh cap 1, a fan 2, a water collecting device 3, a round sealing gasket 4, a curved pipe 5, a square sealing gasket 6, a heat exchanger 7, a merging pipe 8, a small square sealing gasket 9, a telescopic air duct 10, an air nozzle 11, an air nozzle fixing frame 12 and a merging pipe fixing frame 13.

[0037] Position and function of each structure:

[0038] The mesh cap 1, preferably a steel mesh cap, is arranged at the end of the axial flow fan to further condense water vapor and provide safety precautions;

[0039] Axial flow fan 2, arranged on the main pipeline to provide water vapor collection power for the pipeline;

[0040] The water collecting device 3 is located below the axial flow fan and is used to collect the condensed water vapor on the mesh cap 1 to prevent the uncondensed water vapor at the air outlet from condensing and corroding the equipment, and is connected and fixed to the bracket through the water collecting support frame;

[0041] A round sealing gasket 4 is arranged at the end of the axial flow fan to seal the pipeline;

[0042] The elbow 5 is arranged on the main pipe and plays a connecting role;

[0043] The square sealing gasket 6 is arranged between the heat exchanger and the elbow to seal the pipeline;

[0044] The heat exchanger 7 is arranged on the main pipe to connect the elbow and the merging pipe, and plays the role of liquefying water vapor;

[0045] The merging pipe 8 is arranged at the front end of the heat exchanger to merge the air nozzles on both sides, thereby reducing the number of axial flow fans;

[0046] Small square gasket 9, plays a sealing role between the branch line and the main line;

[0047] The telescopic air duct 10, the air nozzle is connected to the water shield in the quenching upper assembly. Since the water shield needs to be raised and lowered, the telescopic air duct can better adapt to the position change of the water shield when the water shield is raised and lowered;

[0048] One end of the air nozzle 11 is connected to the telescopic air duct 10, and the other end is welded and fixed to both sides of the water shield through the air nozzle fixing frame 12 to collect the rising water mist.

[0049] The air nozzle fixing frame 12 fixes the air nozzle 11 to the water shield.

[0050] The merging pipe fixing frame 13 fixes the merging pipe 8 to the bracket.

[0051] The working process of this embodiment is as follows: when the water shield of the quenching upper component is lowered into place, the axial flow fan of the drainage mist device is started, the cold circulating water of the heat exchanger begins to be supplied and circulated, and the water mist is liquefied and refluxed; when the water shield of the upper component is lifted, the axial flow fan of the drainage mist device is stopped, and the cold circulating water of the heat exchanger stops supplying.

[0052] The present invention uses an axial flow fan to provide water mist collection power, so that the water mist is liquefied through heat exchange in the heat exchanger and then flows back to the water pool along the side wall of the pipeline. The present invention is used for collecting and liquefying water mist in water-cooled quenching and wind-mist quenching, which can effectively prevent the diffusion of water mist, reduce the air humidity in the factory, extend the service life of upper related equipment and electrical components, and reduce the damage to the equipment in the factory due to excessive humidity.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
