The separator main body 1 is connected to the water collection box 2. The bottom of the oil-water separation box 21 is connected to a pressure pipe. 23. The lower end of the pressure pipe 23 extends into the main body 1 of the separator.

After the sewage to be treated enters the inner casing 11 of the separator main body 1, the sewage reaches a steady flow state under the buoyancy balance of the thin-walled tube 111. Difference in specific gravity, in which the upper layer precipitates oil, the lower layer is clean water, the separated oil floats up into the oil collection box 24, and is discharged through the oil discharge pipe 211, and the clean water in the lower layer flows upward from the lower end of the pressure pipe 23 into the oil-water separation box 21, and discharge through the drain pipe 22, which is convenient for recycling.

In a preferred embodiment, the lower end of the pressure pipe 23 extends downwards to the bottom of the separator main body 1, and the pressure pipe 23 is arranged at a position away from the opening end of the inner casing 11, since the bottom of the separator main body 1 is far away from the inner casing 11 The position of the open end of the separator is relatively pure water, and the lower end of the pressure pipe 23 is arranged at this position to collect the purest water in the separator main body 1 and discharge the water.

According to the difference in specific gravity between oil and water, the utility model is based on the principle that oil floats on the water surface, so that oil and water are separated, and the separation speed is fast, the separation effect is good, and energy saving and environmental protection are achieved.

As shown in FIG. 9 , the height of the top surface of the oil collection box 24 in this embodiment is lower than that of the oil-water separation box 21 . Since the oil is lighter than water, the oil separated out from the inner casing 11 of the separator main body 1 rises rapidly, and when the liquid level of the floating oil is higher than the height of the top surface of the oil collection box 24, the oil enters the oil collection box 24 is collected and then discharged through the oil discharge pipe 211. The top surface height of the oil collection box 24 is lower than the top surface height of the oil-water separation box 21 to ensure that the oil can be smoothly discharged from the oil-water separation box 24 and will not flow into the oil-water separation box 21, improving the oil-water separation box. seperate effect. Further, the top of the oil-water separation box 21 is connected to the top of the water collection box 2, which effectively prevents the precipitated oil from flowing into the oil-water separation box 21 and improves the oil-water separation effect.

Since the oil is lighter than water, the oil separated out from the inner casing 11 of the separator main body 1 rises quickly, while the water enters the oil-water separation box 21 from the lower end of the pressure tube 23 and is discharged due to the pressure, which improves the separation of oil and water. Effect.

As shown in Fig. 1, Fig. 6 and Fig. 7, the industrial cleaning machine oil-water separator of the present embodiment also includes a coarse filter 3, and the coarse filter 3 includes a gland 31, a coarse filter screen 32, a sewage filter for accessing sewage The water inlet 34 and the coarse filter outlet 33, the sewage water inlet 34 and the coarse filter outlet 33 are respectively connected to the upper end and the lower end of the coarse filter 3, and the gland 31 is arranged on the top of the coarse filter 3, and the coarse filter is 32 is arranged in the coarse filter 3 , and the coarse filter 3 communicates with the inner casing 11 through the coarse filter drain 33 .

The oily water is first coarsely filtered by the coarse filter 3 and then enters the main body 1 of the oil-water separator. The coarse filter screen 32 of the coarse filter 3 can ensure that the impurities in the oily water do not directly fall into the separator main body 1, and filter the larger impurities in the coarse filter. On the filter screen 32, on the one hand, the separation effect of the oil and sewage in the inner casing 11 of the separator main body 1 is guaranteed to avoid clogging; The gland 31 takes out the coarse filter 32 to remove impurities, which is easy to operate and improves the reliability of the coarse filter 3 . The oily water filtered by the coarse filter 3 enters the inner casing 11 of the separator main body 1 through the coarse filter drain 33, so that the oil is separated and precipitated quickly, and the oil-water separation speed is improved, and the process of the separation equipment is less, reducing the operation and separation costs of the equipment.

As shown in Figure 3, the industrial cleaning machine oil-water separator of the present embodiment also includes a sewage tank 7, which is provided with a buoyancy balance buoy 8 suspended under the liquid surface of the sewage by relying on the buoyancy of the sewage, and the buoyancy balance The buoy 8 includes an inner buoy 82, an outer buoy 81 and a sewage inlet pipe 71, the inner buoy 82 is sleeved in the inner cavity of the outer buoy 81, the water inlet end of the sewage inlet pipe 71 is connected to the inner buoy 82, and the water outlet of the sewage inlet pipe 71 The end is connected with the sewage water inlet 34 of the strainer 3. Due to the effect of buoyancy balance, the upper end surface of the inner buoy 82 is always equal to or slightly lower than the liquid level of the sewage in the sewage tank 7, and due to the difference in specific gravity of oil and water, the sewage in the sewage tank 7 is left standing for a certain period of time. The oil separated from the upper layer easily enters the inner buoy 82 and flows into the strainer 3 through the sewage water inlet pipe 71, realizing the first oil-water separation before filtration and improving the separation effect of the utility model.

As shown in FIG. 5 , the top of the water collection box 2 of this embodiment is provided with a vacuum port 6 for communicating with outside air. The setting of the vacuum port 6 avoids negative pressure in the water collecting box 2 . After the sewage enters the main body of the separator 1, the oil and water are separated. The oil density is small and located in the upper layer, and the water density is high and located in the lower layer. Therefore, the lower layer of the separator main body 1 is pure water, the upper layer is oil, and the pure water in the lower layer passes through the pressure. The pipe 23 enters the oil-water separation box 21, and the water flowing into the oil-water separation box 21 is discharged through the drain pipe 22, and the water discharged through the drain pipe 22 can be drained into the liquid storage tank for easy recycling.
