The solution treatment or heat treatment process with a rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, tempered glass, etc. is also generally called quenching.

In the quenching process, the temperature of the cooling medium is uneven, and the loss such as quenching distortion, cracking or scrapping can be caused. How to make the medium in the quenching tank flow uniformly and reasonably is always a problem which is regarded by heat treatment workers. In order to ensure that the parts are compensated with required hardness and good mechanical properties after heat treatment, reduce deformation, avoid cracking and the like, a stirring device for cooling media is arranged in a quenching tank at the present stage, but the stirring position of the stirring device cannot be adjusted according to the spreading position of the workpieces, so that energy waste is easily caused, and the requirements of energy conservation and environmental protection are not met.

Furthermore, the liquid guide pipe and the flange plate are both positioned outside the liquid surface of the quenching tank, and the liquid guide pipe is sequentially connected with a centrifugal pump, a variable frequency motor and an electric appliance control cabinet. The liquid guide pipe and the flange plate are both positioned outside the liquid surface of the quenching tank, so that the angle of the liquid outlet pipe can be conveniently adjusted.

Furthermore, the centrifugal pump is also connected with a liquid pumping pipe, and the liquid pumping pipe extends into the position below the liquid level of the quenching tank. The liquid pumping pipe pumps the cooling liquid and discharges the cooling liquid through the liquid guide pipe and the liquid outlet pipe.

Furthermore, angle marks are carved beside the connecting holes in the circumferential direction of the flange plate. The rotation angle of the liquid outlet pipe can be conveniently known, and the direction of the liquid outlet of the spraying unit can be conveniently known.
