Description

Oil-water separator and its oil discharge adjusting device

The invention relates to an oil-water separator, in particular to an oil-water separator and an oil discharge adjusting device.

According to the general metal processing machine, high heat will be generated during the cutting operation, so it is necessary to cool the cutting tool and the workpiece with the cutting fluid (or other oil-water mixture) in a timely manner to prevent damage to the tool and the workpiece. When the cutting fluid is recycled, in addition to filtering the impurities first, the oil and water (cutting fluid and impurity oil) must be separated before they can be recycled.

The general oil-water separator, especially the air-driven oil-water separator, mainly uses a pump (pump) to draw the cutting fluid from the water inlet 6 into a static tank (the cutting fluid enters the static Before the tank, impurities are filtered by a filter tank and most of the oil-water separation operation is performed. As shown in Figure 1, the existing static tank 1 will be provided with a row of oil holes 2 on one side and a side There is a drain hole 3, the vertical height of the bottom of the oil drain hole 2 is slightly higher than the vertical height of the drain hole 3, when the cutting fluid enters through the water inlet hole 6, the air pumping speed is affected by the air pressure. The water level is high and low So that the oil drain hole 2 discharges the oil layer 4 on top of the cutting fluid, and the water hole 5 below the oil layer 4 is drained by the drain hole 3.

However, the pumping speed will be affected by the clogging of the filter tank, so the water inlet speed is getting slower and slower, the water level drops to the oil and cannot be discharged. The air intake must be increased to increase the horsepower and speed of the pump and increase the water intake. However, the adjustment of the pump speed to the water level has a very low instantaneousness and cannot immediately reflect the water level. If the pump speed is too slow, it is too time-consuming. For example, when the pump extraction speed is too fast, the water level is often too high and the water layer The water in 5 will go out from the oil drain hole 2, resulting in the cutting fluid discharged from the oil drain hole 2 will have a high water content, so that the effect of oil and water separation is greatly reduced. In order to cope with the above problems, it needs personnel to monitor at any time As well as adjusting the pumping speed of the pump, it may consume manpower. In addition, the water level cannot be accurately adjusted by the adjustment of the pump speed. If the oil level and the water level are too close when the oil layer is thin, it is easy to adjust the water level and the oil level by the pump speed. 5 water is discharged from the oil drain hole 2. In addition, because the height of the drain hole 3 and the oil drain hole 2 are close, the level must be adjusted during installation, otherwise the effect cannot be achieved, and the flatness of the installation place requires high, so the installation is troublesome.

Therefore, the above is an introduction to the components and composition of an oil-water separator 100 according to a preferred embodiment of the present invention, and then the use characteristics are described as follows:

When the present invention is used, the pump device 20 generates suction power to draw the cutting fluid 90 into the outer pipeline 22, and after filtering the impurities through the filter tank 30 (as shown in FIG. 3) , And then into the pump body 21, and then through the pump body 21, the filtered cutting fluid 90 is filtered through the inner pipe 23 to the oil-water separation tank 41 of the oil-water separation device (such as the fourth Figure Shown), so that the cutting fluid 90 gradually flows upward along the flow holes 423 of each layer 421 of the oil-water separator 42 (as shown in FIGS. 4 and 5). Since the positions of the flow holes 423 are different, the cutting fluid can be increased 90 The time and area of contact with the laminate 421, so that the oil can stick to the laminate 421, so as to achieve the effect of oil-water separation.

Next, after the oil-water separator 42 separates the oil-water separator, the cutting fluid 90 flows into the stationary tank 60 from the top of the oil-water separation tank 41 (as shown in FIGS. 6 to 10). Light, so the water layer 91 in the cutting fluid 90 in the stationary tank 60 settles down and is located at the bottom, while the oil layer 92 in the cutting fluid 90 floats upward and is located at the top.

Thereby, when the oil layer 92 gradually floats upward and passes through the groove 722 of the movable pipe 72 of the oil discharge regulator 70, the oil layer 92 flows into the oil discharge hole 74 inside the oil discharge regulator 70 through the groove 722 ( (As shown in Figs. 10 and 11), it is collected by being discharged outward through the oil discharge hole 74.
