Description

Technical Field

[0001] The present application relates to the technical field of metal rolling, and in particular to a device for monitoring the water volume of a dirty oil tank of a rolling oil distillation device and distillation equipment. Background Art

[0002] Aluminum cold rolling mills and aluminum foil rolling mills need to use rolling oil to cool and lubricate the rollers and rolling materials during the production process. The quality and purity of rolling oil directly affect the rolling process parameters and the surface quality of the rolled materials. During the processing of aluminum strips and foils, the rolling oil is provided to the rolling mill by the oil pump station in a continuous circulation manner. Therefore, during the circulation process, the rolling oil will be polluted in two ways: one is the pollution of mechanical impurities, such as dust, aluminum and aluminum oxide particles; the other is the pollution of lubricating oil, hydraulic oil, etc. (soluble pollution). For mechanical pollution, a plate filter is set in the process to remove solid impurities using the principle of filtration. For soluble heavy oil (relative to rolling oil) pollution, a rolling oil distillation device is used to solve it.

[0003] The distillation device is to process the oil in the rolling mill oil tank by vacuum distillation in the distillation tower, so that the rolling oil is gasified and cooled for recycling, and the soluble heavy oil is discharged into the waste oil tank. In practical applications, the distillation device not only has to process the oil in the rolling mill oil tank, but also the oil collected from the outside ditch, etc. These oils contain a lot of water. When the distillation device is used to process them, the water problem often causes system failure and equipment damage.

[0004] Therefore, how to reduce the water content in the waste oil and reduce the risk of fault alarms in the distillation unit has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In order to achieve the purpose of the utility model, a water volume monitoring device for a dirty oil tank of a rolling oil distillation device is provided, comprising:

[0007] Box and moisture content detection device;

[0009] The water content detection device is installed in the box, and the detection probe of the water content detection device is arranged close to the inclined inner wall;

[0011] According to another aspect of the present application, a distillation device is provided, comprising: a distillation tower body and a water volume monitoring device for a dirty oil tank of the rolling oil distillation device.

[0012] The present application sets a box to place waste oil still, so that the waste oil containing water to be distilled and recovered rolling oil collected from the ditch and other places can be separated into oil and water layers. The density of the oil is low in the upper layer, and the first liquid discharge port on the lower side of the inclined inner wall at the lower end of the box is used to discharge the water after stratification, while the oil in the upper layer is left to be put into the distillation tower for distillation treatment to recover the rolling oil. In addition, the present application also sets a glass transparent observation window at the lower end of the box as an observation window for whether the oil and water layers are separated after standing still and a liquid level scale for the boundary line of the oil layer and the water layer.
