Abstract

The invention relates to quenching oil on line dewater unit. It includes oil feed control valve, backing stage filter, secondary filter, heater, anti-foaming machine, vacuum tank, pressure sensor, cooler, cooling fan, vacuum valve, vacuum pump, cistern, oil pump, and tertiary filter. The oil inlet is set oil feed control valve. The filter is set at the front and back of the heater. The anti-foaming machine is set at the front of the vacuum tank. Its upper is set cooler. Its inner is set pressure sensor. The vacuum valve is set at the front of the cooler. Its side is set cooling fan. Its lower is set cistern whose front and back are set vacuum valve. The lower of the vacuum tank is set the tertiary filter and oil pump. The unit can separate the water from the oil at vacuum by using the characteristic that the boiling point of the liquid is reduced with the lowering of the surface pressure. In addition, it has the advantages of fast impurity removing, on line running, low cost, safe, big quenching oil mass etc.

Description

technical field [0001] The invention relates to a dehydration device, in particular to an online dehydration device for quenching oil, which belongs to the technical field of metal material heat treatment. Background technique [0002] Quenching is an important process in mechanical processing. A small amount of water in the quenching oil will cause great harm to the normal quenching operation: it will deteriorate the cooling performance of the quenching oil and accelerate the aging of the quenching oil. When the water content is greater than 0.1%, it will cause quenching. When the water content is greater than 0.5%, the water at the bottom will suddenly boil during the quenching process, resulting in the risk of quenching oil overflow and fire. How to separate the water and other impurities in the quenching oil becomes the key to ensure the quality of the quenching oil.
