Description

Technical Field

[0001] This utility model belongs to the field of extraction box technology, and more specifically, relates to an extraction modification device that saves costs and increases efficiency. Background Technology

[0002] An extraction chamber is an extraction device that uses mechanical stirring to mix materials in one container and allows them to naturally clarify in another container by gravity, thereby achieving the function of clarification and separation. It is widely used in chemical, metallurgical and pharmaceutical industries and has the advantages of high extraction efficiency, easy maintenance, low energy consumption and strong adaptability.

[0003] In the extraction process, multiple extraction tanks connected in series are typically used to form an extraction line. The aqueous and organic phases of the extraction tanks are connected to the mixing chamber from the end of the clarification chamber via pipes. In existing extraction lines, the mixing chamber and the clarification chamber are in the same row, and the pipes from the clarification chamber to the mixing chamber are long, thus requiring a large amount of pipework for construction. For example, a waste solvent washing device and a washing system for nuclear fuel reprocessing plants disclosed in Chinese invention patent literature (CN202311560823.5) are provided. This invention has multiple mixing and clarification stages, which are arranged in parallel between the organic phase inlet and the organic phase outlet. The mixing and clarification stages are divided into acid washing stages and alkali washing stages, so that the waste solvent can be washed by alternating alkali and acid. However, this method still requires the transfer between adjacent extraction tanks, and the pipeline still has the risk of leakage. At the same time, the crystallization in the pipeline is difficult to clean, requiring a large amount of manpower and resources to stop production for cleaning, unloading and cleaning, which increases the difficulty of operation, reduces production efficiency, and ultimately affects product quality.

[0004] Therefore, we need an extraction modification device that saves costs and increases efficiency. It should be easy to operate and able to directly transport the liquid phase from the clarification chamber to the mixing chamber by alternating extraction tanks, thereby reducing pipeline usage, achieving cost reduction and efficiency improvement, and shortening maintenance and cleaning time. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an extraction modification device that saves costs and increases efficiency. It has a reasonable structure and directly transfers the liquid phase in the clarification chamber to the mixing chamber of the adjacent extraction tank, thereby reducing the use of pipelines, avoiding the risk of pipeline leaks, reducing maintenance frequency and cleaning difficulty, and achieving the goal of cost reduction and efficiency improvement.

[0006] This utility model discloses an extraction modification device for cost reduction and efficiency improvement, comprising an extraction line, wherein the extraction line includes several extraction boxes that are fixed and sealed to each other. The extraction boxes are used for continuous extraction of raw materials to improve extraction efficiency and product quality.

[0007] The extraction chamber includes a mixing chamber and a clarification chamber, which are separated by a baffle. The mixing chamber and clarification chamber of adjacent extraction chambers are alternately arranged to achieve direct transfer of liquid phase, reduce pipeline length, and reduce the risk of leakage.

[0008] The bottom of the mixing chamber at the connection of the extraction boxes, which are fixed and sealed to each other, has an aqueous phase reflux tank and an organic phase reflux tank. These are used to allow the organic and aqueous phases inside the clarification chamber of the adjacent extraction box to flow directly into its mixing chamber for mixing and extraction, ensuring smooth liquid flow and avoiding uneven distribution of organic and aqueous phases in the subsequent mixing chamber.

[0009] As a further improvement of this utility model, the mixing chamber is equipped with a motor and a stirrer. The motor is detachably installed on the top of the mixing chamber, and the stirrer is located inside the mixing chamber. The output shaft of the motor is detachably connected to the stirrer and is used to drive the stirrer to mix the aqueous phase and the organic phase evenly. The evenly mixed liquid phase overflows into the clarification chamber through the baffle.

[0010] As a further improvement of this utility model, the bottom of the agitator is provided with a partition plate to divide the mixing chamber into an upper mixing chamber and a lower liquid inlet chamber; the partition plate has a liquid inlet in the middle, which is used to cooperate with the top agitator to suck the organic phase and water phase that have entered the liquid inlet chamber through the aqueous phase return tank and the organic phase return tank into the mixing chamber, avoiding the use of a pump to extract them, thereby reducing the cost of equipment use and maintenance.

[0011] As a further improvement of this utility model, the clarification chamber is equipped with an aqueous phase reflux device and an organic phase reflux device. The aqueous phase reflux device and the organic phase reflux device are detachably installed on the wall of the clarification chamber, respectively, to reflux the aqueous phase and the organic phase to the mixing chamber of the extraction box on the adjacent side through the aqueous phase reflux tank and the organic phase reflux tank, respectively, to ensure that the liquid phase reflux is efficient and leak-free, and further optimize the extraction process.

[0012] As a further improvement of this utility model, the aqueous phase reflux device includes a first outer folding plate and an inner folding plate. The two ends of the first outer folding plate are respectively fixedly installed on the inner wall of the clarification chamber on the side away from the mixing chamber and on the inner wall of the aqueous phase reflux tank near the adjacent extraction chamber. There is a gap between the bottom of the first outer folding plate and the bottom of the inner wall of the clarification chamber, allowing the aqueous phase located in the lower layer of the clarification chamber to flow into the interior of the first outer folding plate along the gap. The inner folding plate is located inside the first outer folding plate, and its two ends are respectively fixedly installed on the inner wall of the clarification chamber on the side away from the mixing chamber and on the inner wall of the aqueous phase reflux tank near the adjacent extraction chamber. The inner wall of one side of the water phase reflux tank has an inner folding plate whose bottom is fixedly connected to the bottom of the clarification chamber wall. The top of the inner folding plate is lower than the top of the first outer folding plate, which allows the water phase entering from the gap between the bottom of the first outer folding plate and the bottom inner wall of the clarification chamber to overflow into the inner folding plate through the top of the inner folding plate. The bottom of the inner folding plate has a reflux port corresponding to the water phase reflux tank, which guides the water phase overflowing into the inner folding plate into the mixing chamber through the reflux port and the water phase reflux tank, thereby achieving efficient separation of the water phase during reflux and ensuring that the water phase does not mix with the organic phase during the reflux process.

[0013] As a further improvement of this utility model, the organic phase reflux device includes a second outer folding plate and a second reflux port. The two ends of the second outer folding plate are respectively fixedly installed on the inner wall of the clarification chamber away from the mixing chamber and on the inner wall of the organic phase reflux tank near the adjacent extraction chamber. The bottom of the second outer folding plate is fixedly connected to the bottom of the inner wall of the clarification chamber, and is used to allow the organic phase located in the upper layer of the clarification chamber to overflow into the interior of the second outer folding plate. The second reflux port is located in the position of the organic phase reflux tank, and is used to guide the organic phase overflowing into the interior of the second outer folding plate into the mixing chamber through the second reflux port and the organic phase reflux tank, ensuring that the organic phase does not mix with the aqueous phase during the reflux process, further improving the separation effect, thereby ensuring that the organic phase and aqueous phase entering the mixing chamber are evenly distributed, and improving the quality and stability of the extraction.

[0014] As a further improvement of this utility model, a slag discharge port is opened at the bottom of the clarification chamber. The slag discharge port is located between the aqueous phase reflux device and the organic phase reflux device, and is used to discharge the slag in the clarification chamber.

[0015] Compared to existing technologies, the advantages of this invention are as follows: By alternating the mixing and clarification chambers of the extraction tank to achieve multi-stage separation of the residue, the extraction efficiency and separation purity are significantly improved, while reducing the use of pipelines, thereby saving costs and achieving the goal of cost reduction and efficiency improvement; by setting up a water phase reflux device that enters the aqueous phase from the bottom and an organic phase reflux device that overflows into the organic phase from the top, the transport of the aqueous and organic phases to adjacent extraction tanks through pipelines is avoided, reducing the risk of pipeline leaks, lowering maintenance frequency and cleaning difficulty, and making the separation and reflux of the aqueous and organic phases more precise; by setting up a reflux port one corresponding to the aqueous phase reflux tank and a reflux port two corresponding to the organic phase reflux tank, it is ensured that the aqueous and organic phases are accurately refluxed to the mixing chamber respectively, effectively avoiding uneven distribution of the organic and aqueous phases due to mixing, further improving product quality and stability, and optimizing the overall process flow.

[0022] Specific Implementation Example 1: Please refer to... Figures 1-4 An extraction modification device for cost reduction and efficiency improvement includes an extraction line, which includes several extraction boxes 1 that are fixed and sealed to each other. The extraction boxes 1 are used for continuous extraction of raw materials to improve extraction efficiency and product quality.

[0023] Extraction chamber 1 includes a mixing chamber 2 and a clarification chamber 3, which are separated by a baffle 4; the positions of the mixing chamber 2 and the clarification chamber 3 of adjacent extraction chambers 1 are alternated, thereby realizing direct transfer of liquid phase, reducing pipeline length and reducing the risk of leakage.

[0024] like Figure 2 As shown, the single extraction box 1 has an aqueous phase reflux tank 21 and an organic phase reflux tank 22 at the bottom of the mixing chamber 2 where it is connected to the adjacent extraction box 1. These are used to directly transfer the organic phase and aqueous phase inside the clarification chamber 3 of the adjacent extraction box 1 to the mixing chamber 2 of the single extraction box 1 for mixing and extraction, ensuring smooth liquid phase flow and avoiding uneven distribution of organic and aqueous phases in the subsequent mixing chamber 2.

[0025] Specifically, the mixing chamber 2 is equipped with a motor 23 and a stirrer 24. The motor 23 is detachably installed on the top of the mixing chamber 2, and the stirrer 24 is located inside the mixing chamber 2. The output shaft of the motor 23 is detachably connected to the stirrer 24 to drive the stirrer 24 to mix the aqueous phase and the organic phase evenly. The evenly mixed liquid phase overflows into the clarification chamber 3 through the baffle 4.

[0026] Specifically, the bottom of the agitator 24 is provided with a partition plate 25, which is used to divide the mixing chamber 2 into an upper mixing chamber 26 and a lower liquid inlet chamber 27. The partition plate 25 has a liquid inlet 251 in the middle. The agitator 24 at the top of the liquid inlet 251 generates a low-pressure zone at the liquid inlet 251 by rotating, so as to draw the organic phase and the aqueous phase that enter the liquid inlet chamber through the aqueous phase return tank 21 and the organic phase return tank 22 into the mixing chamber 26, avoiding the use of a pump to extract them, thereby reducing the cost of equipment use and maintenance.

[0027] Specifically, such as Figure 3 The clarification chamber 3 shown is equipped with an aqueous phase reflux device 31 and an organic phase reflux device 32. The aqueous phase reflux device 31 and the organic phase reflux device 32 are detachably installed on the wall of the clarification chamber 3, and are used to reflux the aqueous phase and the organic phase to the mixing chamber 2 of the extraction box 1 on the adjacent side through the aqueous phase reflux tank 21 and the organic phase reflux tank 22, respectively, to ensure that the liquid phase reflux is efficient and leak-free, and further optimize the extraction process.

[0028] Specifically, the aqueous phase reflux device 31 includes a first outer folding plate 311 and an inner folding plate 312. The two ends of the first outer folding plate 311 are respectively fixedly installed on the inner wall of the clarification chamber 3 on the side away from the mixing chamber 2 and on the inner wall of the aqueous phase reflux tank 21 near the adjacent extraction tank 1. There is a gap between the bottom of the first outer folding plate 311 and the bottom of the inner wall of the clarification chamber 3. Because the aqueous phase has a relatively higher density than the organic phase, it is located in the lower layer inside the clarification chamber 3. Figure 4As shown, the aqueous phase flows into the interior of the first outer folding plate 311 along the spacing. The inner folding plate 312 is located inside the first outer folding plate 311. The two ends of the inner folding plate 312 are fixedly installed on the inner wall of the clarification chamber 3 on the side away from the mixing chamber 2 and on the inner wall of the aqueous phase reflux tank 21 near the adjacent extraction tank 1, respectively. The bottom of the inner folding plate 312 is fixedly connected to the bottom of the inner wall of the clarification chamber 3. The top of the inner folding plate 312 is lower than the top of the first outer folding plate 311, so that the aqueous phase entering from the gap between the bottom of the first outer folding plate 311 and the bottom inner wall of the clarification chamber 3 overflows into the interior of the inner folding plate 312 through the top of the inner folding plate 312. The bottom of the inner folding plate 312 has a reflux port 313 corresponding to the aqueous phase reflux tank 21, so as to guide the aqueous phase overflowing into the interior of the inner folding plate 31 through the reflux port 313 and the aqueous phase reflux tank 21 into the interior of the mixing chamber 2, so as to achieve efficient separation of aqueous phase reflux and ensure that the aqueous phase does not mix with the organic phase during the reflux process.

[0029] Specifically, the organic phase reflux device 32 includes a second outer folding plate 321 and a second reflux port 322. The two ends of the second outer folding plate 321 are fixedly installed on the inner wall of the clarification chamber 3 on the side away from the mixing chamber 2 and on the inner wall of the organic phase reflux tank 22 near the adjacent extraction tank 1, respectively. The bottom of the second outer folding plate 321 is fixedly connected to the bottom of the inner wall of the clarification chamber 3. Because the organic phase has a lower density than the aqueous phase, it is located in the upper layer inside the clarification chamber 3. Figure 4 As shown, the organic phase overflows into the interior of the second outer baffle plate 321; the position of the second reflux port 322 corresponds to the organic phase reflux tank 22, which is used to guide the organic phase overflowing into the interior of the second outer baffle plate 321 into the mixing chamber through the second reflux port 322 and the organic phase reflux tank 22, ensuring that the organic phase does not mix with the aqueous phase during the reflux process, further improving the separation effect, thereby ensuring that the organic phase and aqueous phase entering the mixing chamber 2 are evenly distributed, and improving the quality and stability of extraction.

[0030] Specifically, a slag discharge port 33 is opened at the bottom of the clarification chamber 3. The slag discharge port 33 is located between the aqueous phase reflux device 31 and the organic phase reflux device 32. It can be opened or closed under the control of the user to discharge the slag in the clarification chamber 3.

[0031] During use, the initial organic phase and aqueous phase are added to the mixing chamber 2 of any extraction tank 1 in proportion. The stirrer 24 is started by motor 23. After thorough mixing, the liquid overflows into the clarification chamber 3 of the extraction tank 1. Due to the density difference between the organic phase and the aqueous phase, the liquid naturally separates into layers in the clarification chamber 3, with the organic phase floating to the top and the aqueous phase sinking to the bottom. The aqueous phase flows into the interior of the first outer folding plate 311 along the gap between the bottom of the first outer folding plate 311 and the bottom of the inner wall of the clarification chamber 3. As the aqueous phase accumulates inside the first outer folding plate 311, it overflows into the interior of the inner folding plate 312 through the top of the inner folding plate 312 and returns from the return port 313 at the bottom of the inner folding plate 312 and the aqueous phase return port on the adjacent side of the extraction tank 1. The flow channel 21 delivers the organic phase to the mixing chamber 2 of the adjacent extraction tank 1; the organic phase overflows into the second outer folding plate 321 from the top, and is then delivered to the mixing chamber 2 via the return port 322 and the organic phase return channel 22 of the adjacent extraction tank 1; during the delivery of the aqueous and organic phases, the stirrer 24 inside the mixing chamber 2 rotates continuously, creating a low-pressure zone at the inlet 251, thereby drawing the organic and aqueous phases that have entered the inlet chamber via the aqueous phase return channel 21 and the organic phase return channel 22 into the mixing chamber 26; by reducing the use of pipes and pumps, cost savings are achieved, and the risk of pipe leaks is avoided, reducing maintenance frequency and cleaning difficulty, thus achieving the goal of cost reduction and efficiency improvement.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
