Description

Technical Field

During use, cutting fluid will be contaminated by metal chips, oil, bacteria, etc., resulting in its performance degradation, affecting processing quality and production efficiency. With the increasingly stringent environmental protection regulations, the discharge standards of industrial wastewater are constantly improving. The cutting fluid oil-water separator can effectively separate the oil and metal chips in the processing fluid, reduce the pollutant content in the wastewater, and reduce pollution to the environment.

[0003] The traditional method of separating oil and water in cutting fluid is to use the density difference between oil and water. By introducing the cutting fluid mixture into a sedimentation tank and letting it stand or flow slowly, the oil will float to the water surface, while the water will sink to the bottom, and the metal chips will settle on the top of the filter plate. The oil on the top of the water surface is then absorbed using an oil-absorbing cloth, and the cutting fluid is then recycled.

[0004] However, this method requires the oil to stand for a period of time before it can float to the water surface, and some oil-water separation devices cannot continuously adsorb the oil on the water surface, resulting in low oil-water separation efficiency. In addition, the filter plate is easily clogged by metal chips, and the filter plate is fixed inside the sedimentation tank. When the filter plate is clogged, it is inconvenient to remove it and clean the filter holes on the filter plate.
