Metal product quenching medium cyclic utilization device

Abstract

The invention relates to a metal product quenching medium cyclic utilization device. The device comprises a heating furnace, a spray chamber, an infiltration groove, an elution chamber, a liquid storage tank, a quenching groove and a melting convergence groove, wherein a liquid conveying pipeline is arranged between one end of the insulating furnace door of the heating furnace and a water pump in the liquid storage tank; a spray water conveying pipeline is arranged between the other end of the insulating furnace door and the spray chamber; the melting convergence groove is arranged above the quenching groove; a spray water splash guard is covered in the melting convergence groove; the spray water splash guard is provided with a splash-proof cover plate; a spray water branch is divided from the spray water conveying pipeline at the position of the melting convergence groove; the branch is communicated with the melting convergence groove; an electromagnetic valve is added on the spray water branch; a temperature controller is connected with the quenching groove; and a medium conveying pipeline, a medium reflux pipeline, the melting convergence groove and the quenching groove constitute a medium circulation circuit. By using the device of the invention, the recovery and cyclic utilization of the medium are both performed in the melting convergence groove automatically, the procedures of medium recovery are reduced to the minimum, the operation is safe; and the medium can not be wasted and the environment can not be polluted.

Description

technical field [0001] The invention relates to a device for reducing and recycling the medium in the quenching and spraying water of metal parts, in particular, the metal parts are quenched by using the heat released during the quenching and cooling process of metal parts to evaporate the spraying water to recover the medium Media recycling device. Background technique [0002] In the production process of quenching steel shovels or other metal parts with large continuous operations, the rinsing and soaking water and the recycled spray water are poured into the liquid storage pool together. After a long time of use, the liquid in the liquid storage pool will The concentration of the contained medium will increase, and the amount of liquid will also increase. Generally, the liquid storage tank is set to three levels, and the medium is recovered by using the temperature difference method. When the concentration of the medium in the liquid storage tank reaches a certain level,...

Problems solved by technology

The disadvantages of this mode are firstly that it requires a large area of ​​the site, and secondly that manual harvesting and drying not only wastes manpower, but also is greatly affected by the natural environment such as weather and site, and will cause secondary pollution.

Disadvantages of this method: first, clean water is wasted, and second, scale is easy to form in the water pipes and cause blockage, requiring frequent maintenance and repairs
