Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically a dynamic extraction and separation unit for herbicide production. Background Technology

[0002] Extraction and separation technology is one of the key steps in the herbicide production process. Its effectiveness directly affects the purity, yield, and production cost of the final product. In the herbicide production process, it is often necessary to take advantage of the differences in solubility of different components in specific solvents and separate the target product from the complex reaction mixture through liquid-liquid extraction.

[0003] However, in actual production applications, traditional mixing and clarification tanks typically separate mixing and separation into two independent spaces or equipment units, resulting in a relatively large overall structure. Furthermore, the two phases are easily disturbed during the transfer process, affecting separation efficiency and stability. In addition, a single stirring and mixing method often leads to insufficient contact between the light and heavy phases, limiting mass transfer efficiency, and the resulting droplets are of uneven size, which can easily cause emulsification or breakage, thus affecting the subsequent stratification speed and separation effect. At the same time, during dynamic extraction, the phase interface is difficult to control. After the two phases are separated, impurities are easily accumulated or blockages occur at the outlet of the light phase, affecting the continuous and stable operation of the equipment.

[0004] Therefore, to address the above issues, it is necessary to develop an extraction and separation unit for herbicide production to achieve a close integration of mixing and separation functions, enhance the disturbance and mass transfer between the two phases, improve extraction efficiency, and solve the problem of discharge blockage, thereby meeting the demand for efficient and stable separation equipment in the industrial production of herbicides. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic extraction and separation unit for herbicide production, which has the advantages of compact structure, high mass transfer efficiency, good separation effect, stable operation and effective prevention of discharge blockage, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dynamic extraction and separation unit for herbicide production includes:

[0008] Lower tank body;

[0009] The lower end of the upper tank is connected to the upper end of the lower tank via a butterfly valve.

[0010] A mixing tank is fixed to the side wall of the upper tank, and a mixing mechanism is installed inside the mixing tank.

[0011] A light phase input component is located on the upper part of the outer peripheral wall of the upper tank and is used to input the light phase;

[0012] The multiple phase input component is located at the upper end of the upper tank and is used to input multiple phases;

[0013] A connecting groove is formed through the inner wall of the upper tank to connect the interior of the upper tank with the interior of the mixing tank.

[0014] Both the retaining ring and the support ring are fixed to the inner wall of the upper tank, and a guide slide is formed between them;

[0015] The inner magnet ring is slidably positioned within the guide rail.

[0016] An electromagnetic lifting mechanism is installed on the outer peripheral wall of the upper tank. The electromagnetic lifting mechanism includes an upper arc-shaped block and a lower arc-shaped block fixed to the outer peripheral wall of the upper tank. An electric cylinder is fixed to the upper arc-shaped block. An electromagnet is fixed to the lower end of the output shaft of the electric cylinder. The electromagnet is arc-shaped. There is a gap between the concave surface of the electromagnet and the outer peripheral wall of the upper tank. An inner magnetic ring is slidably installed on the inner wall of the upper tank. The inner magnetic ring and the electromagnet are magnetically attracted to each other. A second fixed ring is fixed to the inner wall of the inner magnetic ring. Multiple connecting blocks are fixed to the inner wall of the second fixed ring. A turbulence mechanism is fixed to one end of the connecting block near the center of the second fixed ring.

[0017] The repetitive phase output component is located on the lower part of the outer peripheral wall of the lower tank and is used to output the repetitive phase.

[0018] The light phase output component is installed through the lower end of the lower tank and is used to output the light phase.

[0019] Preferably, a support mechanism is fixed to the outer peripheral wall of the lower tank body. The support mechanism includes a first fixing ring fixed to the outer peripheral wall of the lower tank body and a plurality of support legs fixed to the outer peripheral wall of the first fixing ring.

[0020] It is worth noting that by setting up a support mechanism, a stable installation foundation can be provided for the entire extraction and separation unit. The first fixing ring is fixed to the outer peripheral wall of the lower tank, and then multiple support legs are evenly distributed and fixed to the first fixing ring. This structural design allows the weight of the equipment to be evenly transferred to the support legs, ensuring the stability and verticality of the equipment during operation and avoiding tilting or shaking caused by uneven ground or equipment vibration.

[0021] Preferably, the stirring mechanism includes a motor fixed to the upper end of the stirring tank, a rotating rod fixed to the lower end of the motor output shaft, a fixed cylinder fixed to the outer peripheral wall of the rotating rod, and a plurality of stirring blocks fixed to the outer peripheral wall of the fixed cylinder.

[0022] It is worth noting that the stirring mechanism adopts a top-driven approach, with the motor installed at the top of the stirring tank. The motor drives the fixed cylinder and stirring blocks to rotate via a rotating rod. This structure ensures that the stirring components are completely located inside the stirring tank, avoiding the leakage risk that may occur if a drive shaft is placed at the bottom of the stirring tank. Multiple stirring blocks are distributed on the outer peripheral wall of the fixed cylinder, which can generate multi-directional shearing and mixing effects on the light and heavy phase liquids entering the stirring tank during rotation. This causes the two phase liquids to disperse rapidly, forming fine droplets, which greatly increases the contact area between the two phases, thereby significantly improving mass transfer efficiency and extraction rate.

[0023] Preferably, the light phase input component includes a light phase feed pipe that is disposed through the upper part of the outer peripheral wall of the upper tank and a first valve body disposed on the light phase feed pipe; the heavy phase input component includes a heavy phase feed pipe that is disposed through the upper end of the upper tank and a second valve body disposed on the heavy phase feed pipe.

[0024] It is worth noting that placing the light phase feed pipe on the upper part of the outer peripheral wall of the upper tank conforms to the characteristics of light phase having low density and naturally floating, allowing the light phase to quickly form a light phase layer at the top after entering. Placing the heavy phase feed pipe at the upper end of the upper tank allows the heavy phase to directly enter the bottom area of ​​the tank with a certain drop, which is conducive to its downward settling and forming a reverse contact with the light phase. The first valve body and the second valve body are respectively installed on the two feed pipes, which can independently and accurately control the feed flow rate and feeding timing of the light and heavy phases, ensuring the accuracy of the initial phase ratio.

[0025] Preferably, the heavy phase output assembly includes a heavy phase discharge pipe that is disposed through the lower part of the outer peripheral wall of the lower tank and a third valve body disposed on the heavy phase discharge pipe; the light phase output assembly includes a light phase discharge pipe that is disposed through the lower end of the lower tank and a fourth valve body disposed on the light phase discharge pipe.

[0026] It is worth noting that the heavy phase discharge pipe is located on the lower part of the outer peripheral wall of the lower tank, which is exactly in the bottom area where the heavy phase accumulates. This allows for the maximum extraction of pure heavy phase and avoids the entrainment of light phase. The light phase discharge pipe is located at the lower end of the lower tank. This is an unconventional but highly innovative design. It works in conjunction with the structure in which the upper and lower tanks are connected by a butterfly valve. After extraction is completed and the tank has been allowed to settle and separate, the butterfly valve is closed, and the lower tank becomes an independent sealed container. At this time, the fourth valve is opened, and the light phase located in the upper part can be discharged from the light phase discharge pipe at the bottom under pressure or by pumping.

[0027] Preferably, the turbulence mechanism includes a cylindrical box fixed to one end of the connecting block near the center of the second fixed ring. The cylindrical box has a hollow structure. A pump body is fixed to the inner wall of the cylindrical box. A pumping end of the pump body is fixed to a pumping pipe, and an outlet end is fixed to an outlet pipe. The outlet pipe passes through the cylindrical box and extends to the top of the cylindrical box and is vertically upward. The pumping pipe passes through the bottom of the cylindrical box and extends to the bottom of the cylindrical box.

[0028] It is worth noting that this is an active turbulence scheme. When the inner magnetic ring drives the entire turbulence mechanism to rise and fall, the pump works synchronously, drawing liquid from the bottom of the cylindrical box through the liquid extraction pipe, and then spraying the liquid at high speed to the top of the cylindrical box through the vertically upward liquid outlet pipe. This process achieves two technical effects: First, it forcibly transports the lower layer of liquid to the upper layer, forming a strong vertical circulation flow in the tank, which greatly enhances the mass transfer between the light and heavy phases throughout the entire tank, breaking the limitation that traditional stirring can only affect local areas; Second, the upward jet flow can effectively impact and disperse impurities or flocs that may accumulate in the light phase near the light phase outlet, causing them to re-participate in the circulation or settle, thereby preventing the blockage problem of the light phase outlet pipe.

[0029] Preferably, the turbulence mechanism includes a first fixed post fixed to one end of the connecting block near the center of the second fixed ring, and a conical groove is provided through the upper end of the first fixed post, the diameter of the upper end face of the conical groove being smaller than the diameter of the lower end face.

[0030] It is worth noting that this is a passive flow disturbance scheme. The conical groove on the first fixed column, with its structure of being smaller at the top and larger at the bottom, forms a fluid guiding channel. When the inner magnetic ring drives the first fixed column to rise in the liquid, the liquid below will relatively enter the larger diameter at the bottom of the conical groove due to inertia. As the first fixed column continues to rise, the liquid entering the conical groove is compressed and accelerated out through the smaller diameter at the top, forming an upward jet. Similarly, when the first fixed column descends, the liquid above will also be guided downward. This design does not require an additional power source. It can transform simple vertical motion into efficient directional flow disturbance simply through lifting and lowering motion and special geometry. While saving energy, it can also disturb the liquid in the tank, promote the dispersion and merging of droplets, and optimize the mass transfer and separation environment.

[0031] Preferably, the turbulence-disrupting mechanism is a second fixed column.

[0032] It is worth noting that the second fixed column itself is a solid columnar structure. When the inner magnetic ring drives it to reciprocate up and down in the tank, the second fixed column exerts a physical pushing and squeezing effect on the surrounding liquid through the change of its spatial position. This pushing can destroy the static boundary layer and concentration gradient that may exist in the liquid, and promote more collisions and contacts between light and heavy phase droplets, thereby achieving the purpose of enhancing mass transfer. Although its turbulence intensity is not as good as the previous two schemes, its structure is extremely simple, there are no vulnerable parts, the manufacturing cost is low, and it is maintenance-free. It is suitable for working conditions where the requirements for turbulence intensity are not high or the materials being processed are relatively mild, providing users with a more cost-effective option.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0034] 1. This utility model achieves a compact integration of mixing and separation functions by connecting the upper and lower tanks via a butterfly valve and installing a light phase discharge pipe at the bottom of the lower tank. During extraction, the butterfly valve is opened, allowing the light and heavy phases to mix and transfer within the space connecting the upper and lower tanks. After settling and stratification, the butterfly valve is closed, making the lower tank an independent, sealed container, with the light phase accumulating at the top and discharging through the bottom discharge pipe. This structure effectively solves the problems of large size and susceptibility to interference during phase transfer caused by the separation of mixing and separation units in traditional equipment, while avoiding the drawback of easy blockage at the light phase discharge port, ensuring continuous and stable operation of the equipment.

[0035] 2. This utility model significantly enhances the two-phase mass transfer process by setting an electromagnetic lifting mechanism to drive the turbulence mechanism to reciprocate within the tank. The electric cylinder drives the arc-shaped electromagnet to rise and fall, and the inner magnet ring and the turbulence mechanism move synchronously through magnetic force. During the rising and falling process, the turbulence mechanism generates vertical disturbances to the liquid. This dynamic disturbance breaks the limitation of single stirring affecting only a local area, making the contact between the light and heavy phases more sufficient and greatly improving the mass transfer efficiency. It solves the problems of uneven two-phase mixing and limited mass transfer in traditional equipment.

[0036] 3. This utility model, through the diversified design of the turbulence mechanism, can adapt to different working conditions and optimize the separation effect. When the cylindrical box is combined with the pump body, the liquid in the lower layer is actively sprayed upward through the liquid extraction pipe and the vertical liquid outlet pipe, which not only enhances vertical mass transfer, but also impacts and disperses impurities near the outlet of the light phase, preventing blockage from the source. When the first fixed column with a conical groove is used, the liquid is guided and accelerated by the lifting motion, realizing energy-saving and efficient passive turbulence. When the second fixed column is used, the static boundary layer of the liquid is destroyed by the solid push, providing an economical and reliable turbulence solution. All three methods can promote droplet dispersion and merging, accelerate the stratification speed, and solve the problems of difficult phase interface control and poor stratification effect of traditional equipment.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] To address the problems of existing technologies, such as bulky structure, fragmented mixing and separation functions, insufficient two-phase contact leading to limited mass transfer efficiency, difficulty in phase interface control, and easy clogging of the light phase outlet, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-8 ;

[0048] A dynamic extraction and separation unit for herbicide production includes:

[0049] Lower tank 1;

[0050] The upper tank 5 is connected at its lower end to the upper end of the lower tank 1 via a butterfly valve 4;

[0051] The mixing tank 6 is fixed to the side wall of the upper tank 5, and the mixing tank 6 is equipped with a mixing mechanism.

[0052] A light phase input component is located on the upper part of the outer peripheral wall of the upper tank 5 and is used to input the light phase;

[0053] The duplicate phase input component is located at the upper end of the upper tank 5 and is used to input duplicate phases;

[0054] A connecting groove 15 is formed through the inner wall of the upper tank 5 to connect the interior of the upper tank 5 with the interior of the mixing tank 6.

[0055] The retaining ring 16 and the support ring 17 are both fixed to the inner wall of the upper tank 5, and a guide slide is formed between them;

[0056] The inner magnet ring 22 is slidably disposed within the guide rail;

[0057] An electromagnetic lifting mechanism is installed on the outer peripheral wall of the upper tank 5. The electromagnetic lifting mechanism includes an upper arc-shaped block 18 and a lower arc-shaped block 21 fixed to the outer peripheral wall of the upper tank 5. An electric cylinder 19 is fixed to the upper arc-shaped block 18. An electromagnet 20 is fixed to the lower end of the output shaft of the electric cylinder 19. The electromagnet 20 is arc-shaped. There is a gap between the concave surface of the electromagnet 20 and the outer peripheral wall of the upper tank 5. An inner magnetic ring 22 is slidably installed on the inner wall of the upper tank 5. The inner magnetic ring 22 and the electromagnet 20 are magnetically attracted to each other. A second fixed ring 23 is fixed to the inner wall of the inner magnetic ring 22. A plurality of connecting blocks 24 are fixed to the inner wall of the second fixed ring 23. A turbulence mechanism is fixed to one end of the connecting block 24 near the center of the second fixed ring 23.

[0058] The repetitive phase output component is located on the lower part of the outer peripheral wall of the lower tank 1 and is used to output the repetitive phase.

[0059] The light phase output component is installed through the lower end of the lower tank 1 and is used to output the light phase.

[0060] It should be noted that the retaining ring 16 and the support ring 17 are fixed to the inner wall of the upper tank 5, forming a guide slide between them. The inner magnetic ring 22 is accommodated in this slide and slides up and down along it, thereby limiting the movement range of the inner magnetic ring 22 and preventing it from falling out of its predetermined track or interfering with the butterfly valve 4. The arc-shaped concave surface of the electromagnet 20 is non-contact with the outer peripheral wall of the upper tank 5, with a 1-5mm annular gap between them. This design allows the magnetic force of the electromagnet 20 to penetrate the tank wall of the upper tank 5, which is made of non-magnetic material, and attract the inner magnetic ring 22 to move synchronously when the electromagnet 20 is raised and lowered by the electric cylinder 19, while avoiding mechanical friction.

[0061] In this embodiment, specifically, a support mechanism is fixedly connected to the outer peripheral wall of the lower tank 1. The support mechanism includes a first fixing ring 2 fixedly connected to the outer peripheral wall of the lower tank 1 and a plurality of support legs 3 fixedly connected to the outer peripheral wall of the first fixing ring 2.

[0062] In this embodiment, specifically, the stirring mechanism includes a motor 61 fixed to the upper end of the stirring tank 6, a rotating rod 62 fixed to the lower end of the output shaft of the motor 61, a fixed cylinder 63 fixed to the outer peripheral wall of the rotating rod 62, and a plurality of stirring blocks 64 fixed to the outer peripheral wall of the fixed cylinder 63.

[0063] In this embodiment, specifically, the light phase input component includes a light phase feed pipe 7 that is disposed through the upper part of the outer peripheral wall of the upper tank 5 and a first valve body 8 disposed on the light phase feed pipe 7; the heavy phase input component includes a heavy phase feed pipe 9 that is disposed through the upper end of the upper tank 5 and a second valve body 10 disposed on the heavy phase feed pipe 9.

[0064] In this embodiment, specifically, the heavy phase output component includes a heavy phase discharge pipe 11 that is disposed through the lower part of the outer peripheral wall of the lower tank 1 and a third valve body 12 disposed on the heavy phase discharge pipe 11; the light phase output component includes a light phase discharge pipe 13 that is disposed through the lower end of the lower tank 1 and a fourth valve body 14 disposed on the light phase discharge pipe 13.

[0065] Example 1: In this example, specifically, the turbulence mechanism includes a cylindrical box 25 fixed to one end of the connecting block 24 near the center of the second fixed ring 23. The cylindrical box 25 is a hollow structure. A pump body 26 is fixed to the inner wall of the cylindrical box 25. A pumping pipe 27 is fixed to the pumping end of the pump body 26, and an outlet pipe 28 is fixed to the outlet end. The outlet pipe 28 passes through the cylindrical box 25 and extends to the top of the cylindrical box 25 and is set vertically upward. The pumping pipe 27 passes through the lower end of the cylindrical box 25 and extends to the bottom of the cylindrical box 25.

[0066] It should be noted that in this embodiment, a battery, a controller and a wireless transceiver are also fixedly connected to the inner wall of the cylindrical box 25 for remote control of the pump body 26.

[0067] This embodiment adopts an active turbulence scheme. Through the coordination of the pump body 26 and the lifting motion, forced vertical circulation of the liquid in the tank is achieved. When the inner magnetic ring 22 drives the cylindrical box 25 to rise and fall, the pump body 26 draws liquid from below through the liquid extraction pipe 27, and then sprays it upward at high speed through the vertically upward liquid outlet pipe 28. This process not only forms strong vertical convection throughout the entire tank, enhancing the mass transfer efficiency of the light and heavy phases, but also effectively impacts and disperses impurities that may accumulate near the light phase outlet, preventing blockage of the light phase outlet pipe 13 from the source and ensuring the long-term stability of the equipment.

[0068] Example 2: In this example, specifically, the turbulence mechanism includes a first fixed post 29 fixed to one end of the connecting block 24 near the center of the second fixed ring 23. The upper end of the first fixed post 29 is provided with a conical groove 30, and the diameter of the upper end face of the conical groove 30 is smaller than the diameter of the lower end face.

[0069] This embodiment adopts a passive flow disturbance scheme, which achieves efficient fluid guidance through the conical groove 30 opened on the first fixed column 29. The upper and lower structure of the conical groove 30 forms a natural flow channel. When the inner magnetic ring 22 drives the first fixed column 29 to rise and fall, the liquid enters the conical groove 30 due to inertia and is accelerated and squeezed out, transforming simple vertical motion into directional jet. This design does not require an additional power source, and achieves effective disturbance of the liquid in the tank while saving energy, promoting the dispersion and merging of droplets, optimizing the mass transfer and separation environment, and is particularly suitable for working conditions with energy consumption requirements.

[0070] Example 3: In this example, specifically, the turbulence mechanism is the second fixed column 31.

[0071] This embodiment adopts the most basic and economical turbulence scheme, which achieves physical turbulence through the physical structure of the second fixed column 31. When the inner magnetic ring 22 drives the second fixed column 31 to reciprocate up and down in the tank, the second fixed column 31 exerts a pushing and squeezing effect on the surrounding liquid through the change of its own occupied space, effectively destroying the static boundary layer and concentration gradient that may exist in the liquid, and promoting more collisions and contacts between light and heavy phase droplets. This scheme has an extremely simple structure, no vulnerable parts, low manufacturing cost and no maintenance, providing users with a cost-effective option, and is suitable for mild working conditions where the requirements for turbulence intensity are not high.

[0072] Working principle: First, the operator injects materials into the equipment through the light phase input component and the heavy phase input component respectively. The first valve body 8 is opened to allow the light phase to enter the upper part of the upper tank 5 through the light phase feed pipe 7. The second valve body 10 is opened to allow the heavy phase to enter the interior of the upper tank 5 through the heavy phase feed pipe 9. At this time, the butterfly valve 4 is in the open state, and the upper tank 5 and the lower tank 1 are connected to each other.

[0073] Subsequently, the stirring mechanism is started. The motor 61 drives the rotating rod 62 to rotate, which in turn drives the fixed cylinder 63 and multiple stirring blocks 64 to rotate at high speed in the stirring box 6. The stirring box 6 is connected to the interior of the upper tank 5 through the connecting groove 15, so that the light phase and the heavy phase circulate between the stirring box 6 and the upper tank 5 and are fully sheared and mixed to form a fine droplet dispersion system.

[0074] At the same time, the electromagnetic lifting mechanism starts to work. The electric cylinder 19 drives the arc electromagnet 20 to reciprocate up and down along the outer wall of the upper tank 5. The electromagnet 20 attracts the inner magnetic ring 22 through magnetic force, causing the inner magnetic ring 22 to slide synchronously along the inner wall of the upper tank 5. The inner magnetic ring 22 drives the second fixed ring 23 and the connecting block 24 to move, thereby driving the turbulence mechanism fixed to the end of the connecting block 24 to make vertical reciprocating motion in the liquid inside the tank.

[0075] When the structure of Embodiment 1 is adopted, the pump body 26 in the turbulence mechanism is activated, and liquid is drawn from below through the liquid extraction pipe 27, and then sprayed at high speed to the top through the vertically upward liquid outlet pipe 28, forming a forced vertical circulation flow in the tank.

[0076] When the structure of Embodiment 2 is adopted, the first fixed column 29 moves in the liquid with the lifting motion. When the liquid passes through the conical groove 30, it is accelerated and guided by the structure that is smaller at the top and larger at the bottom, forming a directional jet.

[0077] When the structure of Embodiment 3 is adopted, the second fixed column 31 physically pushes and squeezes the surrounding liquid through its own physical movement.

[0078] During the aforementioned dynamic disturbance process, the light phase and the heavy phase are in full contact and mass transfer throughout the entire tank, achieving efficient extraction. After extraction, the stirring mechanism and the electromagnetic lifting mechanism are stopped, and the butterfly valve 4 is closed to make the lower tank 1 an independent sealed container. The two phases are allowed to separate into layers, with the light phase accumulating in the upper part of the upper tank 5 and the heavy phase accumulating in the lower part of the lower tank 1. Then, the third valve 12 is opened, and the heavy phase is discharged through the heavy phase outlet pipe 11. The fourth valve 14 is opened, and the light phase is discharged from the light phase outlet pipe 13 at the bottom of the lower tank 1 under pressure or by pumping, thus completing the entire dynamic extraction and separation process.
