Description

Technical Field

[0001] The utility model relates to the technical field of separation switches, in particular to an oil-water extraction separation switch. Background Art

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that uses the different solubilities of components in the system in the solvent to separate the mixture. That is, it is a method of transferring the solute from one solvent to another solvent by using the difference in solubility or distribution coefficient of materials in two immiscible (or slightly soluble) solvents. It is widely used in chemical, metallurgical, food and other industries, and is commonly used in the petroleum refining industry. In addition, the operation of separating the two immiscible liquids after extraction is called liquid separation. In the extraction of oil and water, a separation switch is generally used to separate the oil and water by the different densities of oil and water.

[0003] In the existing oil-water extraction separation switch, a one-way valve and a liquid separation mechanism are provided in the separation switch. The one-way valve controls the overall switch state to control the circulation of the water-oil mixture. The water-oil mixture is at the upper liquid level and the water is at the lower liquid level according to its density difference. The oil and water are separated by the liquid separation mechanism. The liquid separation mechanism and the one-way valve are both arranged in a pipe body. The liquid separation mechanism used for a long time needs to be maintained and replaced. The integrated liquid separation mechanism is not convenient for quick disassembly and replacement separately, which brings certain difficulties to the disassembly and replacement.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an oil-water extraction separation switch is proposed. Utility Model Content

[0016] 1. The utility model is provided with an installation disk, a slot, a positioning pin, a tension spring, a connecting disk, an insert block, a positioning slot and a sealing ring. The insert block is aligned with the slot and inserted. When the insert block is inserted, the inclined surface of the positioning pin is pushed to move the positioning pin outward to stretch the tension spring.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown together, the oil-water extraction separation switch comprises a one-way valve tube 1 and a connecting plate 6, one end of the one-way valve tube 1 is an inlet end, and the other end is an outlet end, and a mounting plate 2 is fixedly provided at the outlet end of the one-way valve tube 1, and the mounting plate 2 is connected to the connecting plate 6, and the connecting plate 6 is connected to a separation tube 10, and the separation tube 10 is provided with an oil discharge port 11;

[0025] A slot 3 is provided on the end surface of the mounting plate 2 opposite to the connecting plate 6. A positioning pin 4 is provided on the slot 3 and slides through the groove wall on the outer peripheral surface of the mounting plate 2. A tension spring 5 is connected between the positioning pin 4 and the mounting plate 2.

[0026] An insert block 7 is fixedly provided on the end surface of the connection plate 6 opposite to the installation plate 2. The insert block 7 is plugged into the slot 3. A positioning groove 8 is opened on one side surface of the insert block 7. The positioning pin 4 is plugged into the positioning groove 8.

[0027] In this embodiment, a drain port 12 is provided at the middle of the bottom end of the inner surface of the separation tube 10, and a filter screen 13 is fixedly installed at one end of the inner surface of the oil drain port 11;

[0028] A hydrophobic oil filter membrane 14 is fixedly provided on one side of the surface of the filter screen 13 close to the connection plate 6 , and an oleophobic water filter membrane 15 is fixedly provided on the upper end of the inner surface of the drain port 12 .

[0029] The hydrophobic oil filter membrane 14 can prevent water from passing through, but allows oil to be filtered and circulated. The oleophobic water filter membrane 15 is opposite to the hydrophobic oil filter membrane 14. Water can be filtered and circulated, but oil cannot pass through, thereby achieving water-oil separation, with a simple structure and low cost.

[0030] In this embodiment, a branch pipe 16 is fixedly connected to the lower end of the drain outlet 12 , and a control handle 17 is provided in the middle of the upper surface of the one-way valve pipe 1 .

[0031] In this embodiment, the lower end of the surface of the positioning pin 4 is arranged as an inclined surface near the opening of the slot 3. When the insert block 7 pushes the inclined surface of the positioning pin 4, the positioning pin 4 is controlled to move, and no manual stretching is required during installation.

[0032] In this embodiment, a sealing ring 9 is provided between the mounting plate 2 and the connecting plate 6. After the one-way valve tube 1 and the separation tube 10 are installed, they fit tightly to each other, thereby enhancing the sealing between the mounting plate 2 and the connecting plate 6 to prevent oil and water leakage.

[0033] Working principle of this embodiment: When using the oil-water extraction separation switch, first, the plug block 7 is aligned with the slot 3 and inserted. When the plug block 7 is inserted, the inclined surface of the positioning pin 4 is pushed, so that the positioning pin 4 moves outward, and the tension spring 5 is stretched. When the positioning pin 4 is aligned with the positioning groove 8, it will be inserted into the positioning groove 8 under the force of the tension spring 5, and the one-way valve tube 1 and the separation tube 10 are connected and installed, and the sealing ring 9 is set to fit each other to increase the sealing of the installation joint to prevent leakage, and then the one-way valve is opened by the control handle 17 to allow the water-oil mixture to enter the separation tube 10. Due to different densities, oil will float on the upper layer and water will settle on the lower layer. The water in the lower layer will enter the drain port 12 through the oleophobic filter membrane 15 and then flow out through the branch pipe 16. The oil in the upper layer will pass through the hydrophobic filter membrane 14 and the filter screen 13 and be discharged from the oil drain port 11, thereby realizing the separation of oil and water. The structure is simple, practical and convenient. After long-term use of the separation tube 10, only the positioning pin 4 needs to be pulled again to disassemble the one-way valve tube 1 and the separation tube 10, which is convenient for the quick disassembly and assembly of the separation tube 10 for replacement and maintenance, thereby improving the convenience of use. This is the working principle of the oil-water extraction separation switch.
