For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] As shown in the figure, an oil-water automatic separation combined device includes a reactor 1, a water receiving tank 7 and an oil receiving tank 8, a bottom valve 3 and an oil-water interface detector 4 are sequentially installed on the liquid outlet pipe 2 at the bottom of the reactor 1, the end of the liquid outlet pipe 2 is connected to the water receiving tank 7 through a first liquid distributor 5, and is connected to the oil receiving tank 8 through a second liquid distributor 6, and a first cut-off valve 9 is installed on the first liquid distributor 5, and a second cut-off valve 10 is installed on the second liquid distributor 6, and the oil-water interface detector 4, the bottom valve 3, the first cut-off valve 9 and the second cut-off valve 10 are all connected to a microprocessor. In this embodiment, the oil-water interface is detected by the oil-water interface detector 4, and the first cut-off valve 9 or the second cut-off valve 10 is controlled to be linked, so that the first cut-off valve 9 or the second cut-off valve 10 is opened, so that water enters the water receiving tank 7 and oil enters the oil receiving tank 8.

[0023] A first liquid level gauge 11 is installed on the water receiving tank 7, and a second liquid level gauge 12 is installed on the oil receiving tank 8. Both the first liquid level gauge 11 and the second liquid level gauge 12 are connected to a microprocessor. The first liquid level gauge 11 and the second liquid level gauge 12 are interlocked with the corresponding first shut-off valve 9 and the second shut-off valve 10 to prevent the material from overflowing due to excessive liquid level, which is safer.

[0024] The end of the liquid outlet pipe 2 is connected to the first liquid distributing pipe 5 through a first U-shaped pipe 13 set downward, and is connected to the second liquid distributing pipe 6 through a second U-shaped pipe 14 set downward, and a first liquid discharge pipe 15 is provided at the bottom of the first U-shaped pipe 13, and a second liquid discharge pipe 18 is provided at the bottom of the second U-shaped pipe 14, a first liquid discharge valve 16 is installed on the first liquid discharge pipe 15, and a second liquid discharge valve 17 is installed on the second liquid discharge pipe 18. In this embodiment, the liquid entering the water receiving tank 7 is pre-stored by the first U-shaped tube 13. Similarly, the liquid entering the oil receiving tank 8 is pre-stored by the second U-shaped tube 14. This prevents mixed liquid from flowing out from the end of the liquid outlet pipe 2 and directly entering the water receiving tank 7 or the oil receiving tank 8 during the period from when the oil-water interface detector 4 detects a change in the detection value to when the interlocking with the first shut-off valve 9 or the second shut-off valve 10 is completed. For example, when water stratification is being performed, water flows out from the end of the liquid outlet pipe 2. When the water-oil interface is reached, the oil-water interface detector 4 detects that this is the detection value corresponding to the oil, and then controls the first shut-off valve 9 to close. During this period, it is very likely that part of the oil will enter the water receiving tank 7. Therefore, the first U-shaped tube 13 and the second U-shaped tube 14 are used for pre-storage, and this part of the mixed liquid will be retained in the U-shaped tube. Finally, the first drain valve 16 or the second drain valve 17 can be opened to discharge it, thereby ensuring the singleness of the liquid in the water receiving tank 7 and the oil receiving tank 8, which is especially practical for the water receiving tank 7 side.

[0025] A three-way joint 19 is connected to the end of the liquid outlet pipe 2, and the outlets at both ends of the three-way joint 19 are connected to the first straight pipe 20, and the first elbow 21 is connected to the end of the first straight pipe 20. The first U-shaped tube 13 is connected to the end of the first elbow 21 near the moisture receiving tank 7, and the second U-shaped tube 14 is connected to the end of the first elbow 21 near the oil receiving tank 8.

[0026] The other end of the first U-shaped tube 13 is connected to the first liquid dispensing tube 5 through the second straight tube 22, and the two ends of the second straight tube 22 are respectively connected to the first U-shaped tube 13 and the first liquid dispensing tube 5 through the second elbow 23; the other end of the second U-shaped tube 14 is connected to the second liquid dispensing tube 6 through the third straight tube 24, and the two ends of the third straight tube 24 are respectively connected to the second U-shaped tube 14 and the second liquid dispensing tube 6 through the third elbow 25.

[0027] In this embodiment, the oil-water interface detector 4 is a short-wave oil-water interface detector 4 .

[0028] The working process of this embodiment is as follows:

[0029] After the reactor 1 has completed the static stratification, the bottom valve 3 of the reactor is opened to discharge the material, and the liquid to be tested passes through the oil-water interface detector 4, and the oil-water interface is detected by using the difference in the absorption of electrical energy by the oil and water media. When the detection value of the oil-water interface detector 4 is greater than 13000Hz, the first cut-off valve 9 on the water receiving tank 7 will be automatically opened through the circuit interlock, and when the detection value is less than 13000Hz, the first cut-off valve 9 will be automatically closed through the circuit interlock, and the second cut-off valve 10 on the oil receiving tank 8 will be opened. When the first liquid level gauge 11 on the water receiving tank 7 or the second liquid level gauge 12 on the oil receiving tank 8 reaches the upper limit, the first cut-off valve 9 or the second cut-off valve 10 will be closed through the liquid level interlock to achieve automatic separation of oil and water.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
