The tank cover mechanism can reduce the quenching liquid sputtering and the quenching liquid steam drifting; When the quenching tank is idle, the cover of the tank can be closed to effectively prevent foreign matter and personnel from falling, and improve safety. The automatic slot cover is driven by the reducer, and the opening and closing mode can be set to automatic and manual modes; The small quenching tank is mostly manual tank cover.

Multifunctional automatic quenching tank carbon dioxide/nitrogen extinguishing device

      Fire extinguishing device adopts awakening pipe line type nitrogen (carbon dioxide) fire extinguishing system. A nitrogen fire extinguishing pipe is arranged on the inside of the quenching oil tank tank, and holes are evenly cut on the fire extinguishing pipe. When the light sensor and the temperature sensor jointly detect the fire, the fire extinguishing process can be automatically started or the sound and light alarm can be switched to manually extinguish the fire. When extinguishing the fire, nitrogen (carbon dioxide) is released in the quenching tank to cover the surface of the oil to isolate oxygen to achieve the extinguishing effect. Nitrogen/carbon dioxide gas is used to extinguish the fire, which is not only safe and reliable but also does not pollute the quenching oil.
