[0002] In the field of organic chemical synthesis, chemical reagents are mostly used for various chemical reactions. Especially in the synthesis of OLED materials and liquid crystal materials, toluene has the characteristics of low cost and stable properties, and is often used as a reaction solvent in large quantities. When toluene is used as a solvent in a reaction kettle for a chemical reaction, sometimes an extraction process is carried out by utilizing the different solubilities of materials and the fact that toluene is insoluble in water. At the end of the extraction stage, it is necessary to separate toluene and water in a timely manner to facilitate subsequent reactions. In the current phase separation operation, when separating, the water level at the lower layer is unstable, which easily leads to a relatively high water content in the separated toluene. Summary of the Utility Model

[0032] In this text, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0034] Referring to Figures 1 - 2 , for the first embodiment of the present utility model, a toluene-water separator is proposed for separating toluene and water, including: a tank body 1 having an accommodation space 2, and a feed port 3 and a first discharge port 4 communicating with the accommodation space 2. The accommodation space 2 is used for storing a mixed solution of toluene and water; a partition plate 5 is arranged in the accommodation space 2. The partition plate 5 divides the accommodation space 2 into an upper space 6 and a lower space 7. The partition plate 5 has a through hole 8, and the through hole 8 communicates the upper space 6 and the lower space 7; a stopper 9 is arranged in the upper space 6 in a lifting manner. When the stopper 9 is lifted or lowered, the through hole 8 is opened or closed.

[0035] In this embodiment, the accommodation space 2 is divided into the upper space 6 and the lower space 7 by the partition plate 5. The mixed solution of toluene and water enters the upper space 6 and the lower space 7 through the feed port 3. After standing for a period of time, using the density difference between toluene and water, toluene floats on the upper layer of water, and water sinks to the lower layer, improving the separation efficiency of toluene and water. At the same time, the design of the partition plate 5 ensures the stability of toluene and water during the separation process, reduces the shaking of the mixed solution in the tank body 1, and improves the controllability of the separation process. After the stopper 9 descends, it can close the through hole 8. By controlling the opening and closing of the through hole 8 with the stopper 9, it can effectively prevent the mixing of toluene and water during the separation process, improving the safety of the separation process. Through the design of the partition plate 5 and the stopper 9, the accuracy of toluene and water during the separation process is ensured, and the purity after separation is improved.

[0036] As a further technical solution, there is also a stopper 9 in the lower space 7. The two stoppers 9 are symmetrically arranged. The stopper 9 has a threaded hole 10 and a round hole 11. It further includes: a bidirectional screw 12 is rotatably arranged in the accommodation space 2, and the bidirectional screw 12 cooperates with the threaded hole 10; there are several limiting rods 13 arranged on the tank body 1. The several limiting rods 13 are respectively located in the upper space 6 and the lower space 7. The limiting rods 13 cooperate with the round holes 11, and the limiting rods 13 are used to limit the sliding of the stopper 9.

[0037] In this embodiment, through the cooperation of the limiting rod 13 and the through hole 8, the block 9 will not rotate with the rotation of the bidirectional screw 12 when the bidirectional screw 12 rotates. Through the cooperation of the bidirectional screw 12 and the threaded hole 10, the lifting of the block 9 can be accurately controlled, so as to more effectively control the flow of toluene and water, and improve the separation efficiency. At the same time, the design of the bidirectional screw 12 and the limiting rod 13 makes the maintenance and cleaning simple and fast, and reduces the maintenance cost.

[0038] As a further technical solution, there are two partition plates 5 and they are conical. The cross-sectional area of the partition plate 5 gradually decreases along the direction close to the through hole 8, and the two partition plates 5 are symmetrically arranged.

[0039] In this embodiment, through the design of the two conical partition plates 5, toluene and water will be guided to the vicinity of the through hole 8 during the rising process, which promotes the separation of toluene and water and improves the separation efficiency. The design of the conical partition plate 5 helps to stabilize the flow state of toluene and water in the tank body 1, reduces the liquid sloshing, and improves the controllability of the separation process. The design of the conical partition plate 5 makes toluene and water naturally gather towards the center, simplifies the operation process. The design of the conical partition plate 5 helps to reduce the mixing of toluene and water during the separation process and improves the safety of the separation process.

[0040] As a further technical solution, it further includes: there are two liquid level tubes 14, and the two liquid level tubes 14 are respectively located in the upper space 6 and the lower space 7; a magnetic flap level gauge 15 is arranged on the tank body 1, the magnetic flap level gauge 15 is communicated with the liquid level tube 14, and the magnetic flap level gauge 15 has a measurement space 16; a floating ball 17 is arranged to lift in the magnetic flap level gauge 15, and the density of the floating ball 17 is between that of toluene and water.

[0041] In this embodiment, through specific material selection, the density of the floating ball 17 is ensured to be between that of water and toluene. At this time, the magnetic flap level gauge 15 can indicate the position of the water level in the accommodation space 2. During actual use, the ratio of toluene and water usually does not remain completely unchanged and will vary with different process conditions. Therefore, during operation, a liquid level mark needs to be made on the magnetic flap level gauge 15. The mark will be below the second discharge port 20. If the liquid level does not exceed this position, the water content in the toluene separated by the second discharge port 20 will not be very high. At this time, continue to add water-containing toluene to perform the phase separation operation again. The amount of water in the lower layer will gradually accumulate, causing the water level to rise. When the liquid level indicated by the magnetic flap level gauge 15 approaches the critical value, after the toluene in the upper layer is separated, the first discharge port 4 in the lower layer can be opened to drain the water, and the subsequent phase separation operation can be continued. This ensures the continuity of production and also ensures that there is basically no excessive water in the separated toluene. The magnetic flap level gauge 15 itself has a remote transmission function, which can transmit signals remotely. Cooperating with the use of solenoid valves, remote control of liquid separation can be achieved, reducing the labor intensity of operators.

[0042] As a further technical solution, it further includes: a rotation driving member 18 is arranged on the tank body 1, and the rotation driving member 18 is used to drive the bidirectional screw 12 to rotate.

[0043] In this embodiment, the design of the rotation driving member 18 enables the operator to control the rotation of the bidirectional screw 12 through simple actions, thereby controlling the lifting of the block 9, simplifying the operation process, and improving the operation convenience. By driving the bidirectional screw 12 to rotate through the rotation driving member 18, the lifting of the block 9 can be controlled more precisely, improving the separation effect. Through the control of the rotation driving member 18, the smooth movement of the block 9 is ensured, reducing the potential risks during the separation process and improving the use safety.

[0044] As a further technical solution, the tank body 1 is provided with an air inlet 19 and a second discharge port 20. The air inlet 19 is located at the top of the upper space 6, and the second discharge port 20 is located at the bottom of the upper space 6.

[0045] In this embodiment, during separation, after the block 9 closes the through hole 8, gas is added into the upper space 6 through the air inlet 19 to make the toluene in the upper space 6 discharge more smoothly, improving the discharging speed. The design of the position of the second discharge port 20 can also ensure that the toluene in the upper space 6 can be separated in time without excessive residue, improving the separation quality and effect.

[0046] As a further technical solution, it further includes: an explosion-proof solenoid valve 21 is arranged on the air inlet 19, and the explosion-proof solenoid valve 21 is used to control the opening and closing of the air inlet 19.

[0047] In this embodiment, the design of the explosion-proof solenoid valve 21 ensures safety when introducing gas, reducing the explosion risk caused by gas leakage. The flow rate and entry time of the gas can be precisely controlled through the explosion-proof solenoid valve 21, improving the controllability of the separation process.

[0048] As a further technical solution, the first discharge port 4 is located at the bottommost part of the lower layer space 7.

[0049] In this embodiment, by arranging the first discharge port 4 at the bottommost part of the lower layer space 7, it can ensure that water can be completely discharged, reducing the possibility of water residue and improving the separation efficiency. The design of the first discharge port 4 enables the operator to easily control the discharge of water, simplifying the operation process.

[0050] As a further technical solution, it further includes: a pressure valve 22 is arranged on the first discharge port 4 and the second discharge port 20, and the pressure valve 22 is also used to control the opening and closing of the first discharge port 4 and the second discharge port 20.

[0051] In this embodiment, the design of the pressure valve 22 ensures that the discharge of water and toluene during the separation process is carried out within a safe pressure range, reducing the safety risk caused by excessive pressure. The discharge rate of water and toluene can be precisely controlled through the pressure valve 22, improving the controllability of the separation process.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
