Gravity oil and water separator

Abstract

The invention discloses a gravity oil and water separator which comprises a main body groove, a separation groove and a circulating pump, wherein the main body groove, the separation groove and the circulating pump are connected through pipelines. The separator can be suitable for acid-washing and alkali-washing. In the invention, the two groove bodies are provided, i.e. the main body groove and the separation groove; liquid in the main body groove and the separation groove forms a circulating pipeline; an overflow hole is arranged on the upper liquid level of the main body groove to ensure that floating oil can flow into a first-stage groove of the separation groove from the overflow hole, thus the floating oil-water in the main body groove can be injected into the separation groove with overflow; the separation groove is divided into three-stage separation, the floating oil flows into an oil receiving barrel from an overflow hole of the separation groove, thus most of oil-water in the separation groove flows out of the overflow hole so that the oil and water can be separated. Acid liquor or alkali liquor in a third-stage groove in the separation groove is conveyed to the main body groove through a pump; and an injection orifice can be configured to ensure that the liquid blows the floating oil on the main body groove to the overflow hole of the main body groove to form the circulating pipeline, and the purpose of separating oil from water is achieved.

Description

technical field [0001] The invention relates to a gravity oil-water separator. Background technique [0002] Before electroplating, powder spraying, painting and other processes on the metal surface, in order to ensure the quality of the process, the workpiece must be treated by pickling and alkali cleaning. Special workpieces also need to undergo cathodic electrolysis or anodic electrolysis, the purpose is to remove grease, rust, etc. on the surface of the workpiece. In the past, when the workpiece was processed in the acid tank or alkali tank, the floating oil generated in the tank could only be taken out manually with a spoon, which seemed very inconvenient, and when the workpiece was taken out of the tank, there was still grease carried out with the workpiece, which affected the workpiece electroplating, Process quality such as dusting. In order to solve the problem of oil-water separation of the floating oil on the pickling or alkali cleaning tank, it is necessary to ...
