Description

Technical Field

[0001] This utility model relates to the field of organic matter separation equipment technology, and in particular to a water washing and stratification device. Background Technology

[0002] Organic compounds can be purified based on the principle of "like dissolves like." For example, some dye intermediates are soluble in toluene (or other organic solvents). The intermediate and toluene are added to a water washing and separation device, followed by rinsing with pure water. After a period of time, the mixture is allowed to stand and separate. Water-soluble impurities in the intermediate dissolve in the aqueous layer, while the intermediate dissolves in the toluene. The aqueous layer is then discharged, yielding a mixture of toluene and the intermediate. Further removal of the toluene yields the purified intermediate. However, in practice, discharging the aqueous layer first, followed by the mixture, and then discharging the aqueous layer slowly to avoid accidental discharge of the mixture, is less efficient. Furthermore, since the mixture and aqueous layer use the same path, small amounts of impurities in the aqueous layer may adhere to this path and contaminate the mixture. Therefore, the initially discharged mixture usually needs to be discarded, ultimately resulting in the loss of the intermediate. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a water washing and stratification device that solves the problems of low efficiency and loss of intermediate materials in existing technologies.

[0004] According to an embodiment of this utility model, a water washing and stratification device includes a tank body, which comprises a widening section, a funnel-shaped section, and a narrowing section connected sequentially from top to bottom. A first inlet pipe is provided within the narrowing section, with one end of the first inlet pipe fixedly extending outside the tank body. A second inlet pipe is provided within the widening section, with one end of the second inlet pipe fixedly extending outside the tank body. A vertical shaft is also rotatably mounted within the widening section, and an agitator plate is fixedly connected to the vertical shaft. A driver for driving the vertical shaft to rotate is also provided outside the widening section. An orifice plate is fixedly connected to the upper end of the funnel-shaped section, and the lower end of the vertical shaft is rotatably connected to the orifice plate. A drain pipe is fixedly connected to the orifice plate, extending fixedly outside the tank body, with one end of the drain pipe inside the tank located above the orifice plate. During discharge, the mixed liquid is first discharged through the drain pipe, and then the remaining water layer is quickly released, thereby improving efficiency. Simultaneously, this prevents the mixed liquid from contacting the lower water layer, thus avoiding the introduction of impurities. Therefore, it solves the problems of low efficiency and loss of intermediate materials in the prior art.

[0005] Furthermore, a balance pipe connecting the inside and outside of the section is fixedly connected to the top of the section.

[0006] Furthermore, the second inlet pipe is fixedly connected to the top of the abbreviated section, and a third inlet pipe extending into the tank body is also fixedly connected to the upper end of the abbreviated section, and the third inlet pipe has an outlet end facing the installation vertical axis.

[0007] Furthermore, the lower end of the vertical shaft is installed with the outlet end facing downwards at an angle.

[0008] Furthermore, the first inlet pipe extends upward to the funnel-shaped section and is laterally fixed to extend outside the funnel-shaped section.

[0009] Furthermore, a mounting base is fixedly connected to the center of the perforated plate, and the lower end of the mounting vertical shaft is rotatably connected to the mounting base. The perforated plate is provided with multiple slots that are equidistantly arranged around the mounting base.

[0010] Furthermore, the perforated plate is also provided with polygonal holes located between two adjacent holes.

[0011] Furthermore, the vertical shaft is fixedly connected to multiple connecting rods, and the agitator plate includes a spiral plate that surrounds all the connecting rods and is fixed to them.

[0012] Furthermore, a first valve and a second valve are respectively installed on the drain pipe and the reduced diameter section, with the second valve located below the first inlet pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Using a drain pipe allows the mixture to be discharged first, followed by a rapid release of the water layer, thus improving efficiency. This also prevents the mixture from coming into contact with residues in the water layer, preventing impurities from mixing into the mixture. This eliminates the need to discard the initial mixture, avoiding significant losses of intermediate materials and solving the problems of low efficiency and intermediate material loss in existing technologies.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, this embodiment provides a water washing and stratification device, which includes a tank body. The tank body includes a wide-diameter section 1, a funnel-shaped section 2, and a narrow-diameter section 3 connected sequentially from top to bottom. The diameter of the wide-diameter section 1 is larger than that of the narrow-diameter section 3. The upper end of the funnel-shaped section 2 is larger and connected to the wide-diameter section 1, while the lower end is smaller and connected to the narrow-diameter section 3. A first inlet pipe 4 is provided inside the narrow-diameter section 3, and one end of the first inlet pipe 4 is fixedly extended to the outside of the tank body. The end of the first inlet pipe 4 located outside the tank body is used to introduce pure water. A second inlet pipe 5 is provided inside the wide-diameter section 1, and the first inlet pipe 6 is... One end of the second inlet pipe 5 extends fixedly outside the tank. The end of the second inlet pipe 5 outside the tank is used to introduce the intermediate substance, and can also be used to introduce methanol. Alternatively, two second inlet pipes 5 can be set to introduce the intermediate substance and methanol respectively. First, pure water is introduced through the first inlet pipe 4, and then methanol and the intermediate substance are introduced. Inside the bracket section 1, a vertical shaft 6 is also rotatably installed, and an agitator 7 is fixedly connected to the vertical shaft 6. Outside the bracket section 1, a driver 8 is also provided to drive the vertical shaft 6 to rotate. The driver 8 can be... When the drive motor and driver 8 are running, the vertical shaft 6 rotates, thereby driving the agitator 7 to agitate the methanol, intermediates, and pure water. Then the driver 8 is stopped, and the mixture is allowed to settle and separate. The upper end of the hopper-shaped section 2 is also fixedly connected to the perforated plate 9, and the lower end of the vertical shaft 6 is rotatably connected to the perforated plate 9. The perforated plate 9 allows materials to pass through vertically, which, together with the agitator 7, achieves better agitation efficiency. Furthermore, the perforated plate 9 is also fixedly connected to the drain pipe 10, which extends to the outside of the tank. One end of the drain pipe 10 inside the tank is located above the perforated plate 9 and communicates with the tank. When pure water is added, the pure water level needs to be lower than the end of the drain pipe 10 inside the tank. After settling, the mixture can be directly discharged through the drain pipe 10, and then the remaining water layer can be quickly released through the narrowing section 3, thereby improving efficiency. At the same time, the mixture and the water layer below do not come into contact, thus avoiding the introduction of impurities. Therefore, the problems of low efficiency and loss of intermediates in the prior art are solved.

[0023] like Figure 1 As shown, the second inlet pipe 5 is fixedly connected to the top of the expansion joint 1. A balance pipe 11 connecting the inside and outside of the expansion joint 1 is also fixedly connected to the top of the expansion joint 1, ensuring pressure balance inside and outside the tank. A third inlet pipe 12 extending into the tank is also fixedly connected to the upper end of the expansion joint 1. The third inlet pipe 12 has an outlet end 13 facing the vertical shaft 6. Pure water can also be introduced through the third inlet pipe 12. During operation, a small amount of pure water can be introduced first, followed by methanol and intermediates. After starting the driver 8, some pure water is introduced through the third inlet pipe 12, allowing impurities to dissolve more efficiently. In pure water, the total amount of pure water introduced must also ensure that the liquid level is below the end of the drain pipe 10 located inside the tank; more specifically, the lower end of the vertical shaft 6 is inclined with the outlet end 13 facing downwards, so that the pure water introduced by the third inlet pipe 12 enters in a downward rushing manner, which, together with the stirring plate 7, can achieve a better mixing effect with the intermediate material inside the tank; furthermore, the first inlet pipe 4 extends upwards to the bucket-shaped section 2 and is horizontally fixed to extend outside the bucket-shaped section 2. The outlet of the first inlet pipe 4 inside the tank is set downwards, so when pure water is added, the water rushes downwards and then turns back upwards, which can more vigorously agitate the methanol and intermediate material.

[0024] like Figure 1 , 2 As shown, a mounting base 14 is fixedly connected to the center of the perforated plate 9. The lower end of the mounting vertical shaft 6 is rotatably connected to the mounting base 14. The perforated plate 9 has multiple slotted holes 15 equidistantly surrounding the mounting base 14. The perforated plate 9 also has polygonal holes 16 located between adjacent slots 15. The mounting shaft provides rotational support for the lower end of the mounting axis. The slotted holes 15 and polygonal holes 16 (as shown in the image)... Figure 2 The pentagons in the diagram allow materials to pass through, which, combined with agitation, makes the materials mix more thoroughly.

[0025] like Figure 1 , 3 As shown, the mounting vertical shaft 6 is fixedly connected to multiple connecting rods 17. The stirring plate 7 includes a spiral plate 18 that surrounds all the connecting rods 17 and is fixed to the connecting rods 17. The spiral plate 18 is spirally surrounded around the mounting vertical shaft 6 and plays a stirring role in the material during the stirring process. At the same time, the spiral plate 18 does not contact other components to prevent interference.

[0026] like Figure 1 As shown, a first valve 19 and a second valve 20 are respectively installed on the drain pipe 10 and the narrowed section 3, and the second valve 20 is located below the first inlet pipe 4. The first valve 19 and the second valve 20 are used to control the opening and closing of the corresponding drain pipe 10 and narrowed section 3. Similarly, valves that control the opening and closing of the first inlet pipe 4, the second inlet pipe 5 and the third inlet pipe 12 are also provided.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
