Description

Technical Field

[0001] This utility model relates to the field of liquid separation device technology, specifically a layered flow plant extraction liquid separation device. Background Technology

[0002] The stratified flow plant extract separator is a specialized device for the separation and purification of plant extracts. It is mainly used in the process of precisely separating extracts of different densities after extracting the effective components from plant raw materials.

[0003] In existing technologies, during plant extraction processes, multiphase extracts (such as mixtures containing volatile oils, water, and ethanol) often exhibit significant differences in density and viscosity among their phases (e.g., the density of volatile oils is typically 0.85–0.95 g / cm³). 3 The density of the ethanol phase is approximately 0.79–0.85 g / cm³. 3 The density of the aqueous phase is 1.0 g / cm³. 3 Furthermore, the extract often contains small amounts of fine impurities such as plant fibers and cell wall fragments. Traditional single-chamber separators rely solely on the natural settling of a single chamber to achieve stratification when processing such systems. Lacking effective buffering and diversion structures, the impact kinetic energy during the injection of the mixed extract can easily trigger violent convection within the chamber, disrupting the natural stratification trend of each phase. Moreover, the natural diffusion of each phase during settling further intensifies interphase mixing. This makes it extremely easy for operators to mix in other phase components due to the presence of transition zones when extracting the target phase. This not only leads to a significant decrease in the purity of the target extract (such as high-purity volatile oil or active polysaccharide solution) but also reduces the recovery rate of effective components. It fails to meet the refined requirements for multiphase component separation in laboratory precision extraction or small-scale production, seriously affecting the efficiency of subsequent purification processes and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a layered flow plant extract separator to solve the problem mentioned in the background art where traditional single-chamber separators cause chaotic layering and make it difficult to accurately separate the liquid phases in multiphase plant extracts (such as extracts containing volatile oils, water, and ethanol).

[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered flow-guiding plant extraction and separation device, comprising a separation tank body, a top cover bolted to the top of the separation tank body, an exhaust port fixedly connected to the top cover, an extraction and separation assembly mounted on the top cover and the separation tank body, a detachable conical distributor mounted on the top cover, a screw fixedly connected to the conical distributor, a self-locking nut threaded onto the screw, an observation window on the separation tank body, a detachable flow-guiding baffle mounted on the separation tank body, an installation assembly mounted on the flow-guiding baffle, and an anti-clogging assembly mounted on the flow-guiding baffle. The screw is detachably mounted on the top cover. The conical distributor disperses the impact force during feeding, avoiding disturbance of the initial mixture. The exhaust port vents air during feeding, preventing air accumulation in the separation tank body that could obstruct liquid flow. The installation assembly adapts to different separation requirements by installing different numbers of flow-guiding baffles. The anti-clogging assembly prevents the flow-guiding holes on the flow-guiding baffle from becoming clogged.

[0006] Based on the preferred embodiment of this technical solution, two sets of flow guide baffles are provided, and the two sets of flow guide baffles are distributed sequentially from top to bottom inside the main body of the liquid separator.

[0007] Based on the preferred embodiment of this technical solution, the diameter of the guide holes in the upper guide baffle is set to 8mm, arranged in a staggered "plum blossom" pattern. The diameter of the guide holes in the lower guide baffle is set to 4mm, arranged in the same plum blossom pattern, and the edges of the holes are all rounded to avoid disturbance of the initial mixture.

[0008] Based on the preferred embodiment of this technical solution, the two sets of flow guide baffles divide the inner cavity of the main body of the separator into upper, middle and lower cavities, thereby adapting to the extraction and separation of three-phase liquids. Furthermore, three sets of observation windows are provided, which are distributed from top to bottom in the upper, middle and lower cavities of the main body of the separator.

[0009] According to the preferred embodiment of this technical solution, the installation component includes a limiting block fixedly connected to both sides of the top cover and a first elastic locking block fixedly connected to the limiting block. The limiting block is set on the main body of the separatory tank, and the first elastic locking block is locked onto the main body of the separatory tank when the flow guide baffle is installed.

[0010] Based on the preferred embodiment of this technical solution, the main body of the separator has an installation groove at the corresponding position of the limiting block. When the flow guide baffle is installed, the limiting block slides into the installation groove of the main body of the separator. The main body of the separator has a slot at the corresponding position of the first elastic block. When the flow guide baffle is installed, the first elastic block is engaged with the slot of the main body of the separator.

[0011] Based on the preferred embodiment of this technical solution, the anti-clogging component includes an arc-shaped baffle plate detachably installed on the top of the flow guide baffle, a support protrusion fixedly connected to the bottom of the arc-shaped baffle plate, and a second elastic locking block fixedly connected to the support protrusion. The second elastic locking block is engaged with the flow guide baffle plate when the arc-shaped baffle plate is installed. The arc-shaped baffle plate prevents residue from entering the flow guide hole of the flow guide baffle plate, while the liquid can flow smoothly into the flow guide hole through the 5mm gap between the arc-shaped baffle plate and the inner wall of the liquid separator body.

[0012] Based on the preferred embodiment of this technical solution, the extraction and separation component includes an inlet fixedly connected to the top cover at one end, a drain pipe fixedly connected to the bottom of the separation tank body at one end, a second one-way valve fixedly connected to the drain pipe, three sets of guide pipes fixedly connected to the upper, middle and lower chambers of the separation tank body at one end, and a first one-way valve fixedly connected to the guide pipes.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The main body of the separator is divided into three independent stratified chambers by two sets of flow guide baffles, with decreasing flow guide hole diameters and visual monitoring through observation windows. Compared with traditional single-chamber separators, this design effectively avoids interference from multiphase liquid mixing, significantly improves separation accuracy and effective component recovery rate, and solves the pain point of chaotic stratification in traditional devices.

[0014] 2. The installation component design consisting of a limiting block and a first elastic locking block enables precise positioning and quick snap-fit ​​of the flow guide baffle without the need for additional fastening tools. The number of baffles can be detached and adjusted to flexibly adapt to the separation requirements of multiphase and two-phase extracts, simplifying the operation process while improving the adaptability of the device and solving the limitation of traditional baffles that cannot be flexibly adjusted.

[0015] 3. The arc-shaped baffle plate can accurately intercept residues to prevent blockage of the guide hole, and the fixed gap can ensure the flow of liquid. It is also detachable for easy maintenance, ensuring a continuous and stable liquid separation process, and solving the problems of easy clogging and inconvenient maintenance of traditional devices.

[0018] 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.

[0019] Please see Figure 1-6 This utility model provides an embodiment: a layered flow-guiding plant extraction and dispensing device, including a dispensing tank body 1, a top cover 21 bolted to the top of the dispensing tank body 1, an exhaust port 23 fixedly connected to the top cover 21, an extraction and dispensing assembly mounted on the top cover 21 and the dispensing tank body 1, a detachable conical distributor 24 mounted on the top cover 21, a screw 25 fixedly connected to the conical distributor 24, a self-locking nut 26 threadedly connected to the screw 25, an observation window 22 on the dispensing tank body 1, a detachable flow-guiding baffle 27 mounted on the dispensing tank body 1, an installation assembly mounted on the flow-guiding baffle 27, and an anti-clogging assembly mounted on the flow-guiding baffle 27. The screw 25 is detachably mounted on the top cover 21. The conical distributor 24 disperses the impact force during feeding to avoid disturbance of the initial mixture. The exhaust port 23 vents air during feeding to prevent... Gas accumulation inside the separator 1 obstructs liquid flow. The installation components adapt to different separation requirements by installing different numbers of flow guide baffles 27. The anti-clogging component prevents the flow guide holes on the flow guide baffles 27 from becoming blocked. The top cover 21 is securely installed with bolts and is easy to disassemble and maintain. The conical liquid distributor 24 is detachably fixed with screws 25 and self-locking nuts 26, which ensures effective dispersion of the impact force during feeding and prevents the initial mixture from being disturbed and disrupting the stratification trend. The vent 23 can timely discharge the gas accumulated in the tank during feeding, eliminating the obstruction of liquid flow by the gas. The observation window 22 enables real-time visual monitoring of the stratification state. The installation components and the anti-clogging component respectively solve the problems of flexible adaptation of the flow guide baffles 27 and flow guide hole blockage, effectively avoiding the multiple pain points of traditional devices such as large feeding impact, gas accumulation interference, poor adaptability, and easy clogging, laying a structural foundation for the accurate separation of multiphase extracts.

[0020] Please see Figure 2 A further solution based on this embodiment is as follows: two sets of flow guide baffles 27 are provided, and the two sets of flow guide baffles 27 are distributed sequentially from top to bottom inside the main body 1 of the separator. Through the sequential distribution design of the two sets of flow guide baffles 27, the interior of the main body 1 of the separator can be divided into multi-level buffer spaces, avoiding direct mixing and stratification of multiphase extracts in a single cavity. This allows liquids of different densities to gradually achieve phase separation in progressively advancing cavities, reducing the thickness of the transition zone between each phase. At the same time, the distribution of the two sets of baffles works in conjunction with the subsequent decreasing aperture design, providing structural support for the orderly sinking of heavy phase liquids and the stable retention of light phase liquids. Compared with a single set of baffles or no baffle design, this significantly improves the hierarchy and stability of multiphase separation, creating favorable conditions for the subsequent accurate extraction of each phase liquid.

[0021] Please see Figure 5 A further solution based on this embodiment is as follows: the diameter of the guide holes in the upper guide baffle 27 is set to 8mm, arranged in a staggered "quincunx" pattern; the diameter of the guide holes in the lower guide baffle 27 is set to 4mm, also arranged in a quincunx pattern, and the edges of the holes are all rounded to avoid disturbance of the initial mixture. By designing a decreasing diameter of 8mm for the upper layer and 4mm for the lower layer guide holes, combined with the staggered arrangement in a quincunx pattern and the rounded edges of the holes, the larger diameter of the upper layer can meet the rapid settling requirements of the heavy phase liquid in the initial mixture. To avoid obstruction of heavy phase flow, the smaller aperture in the lower layer slows down the flow velocity of heavy phase liquid into the lower cavity, preventing the phase interface of the lower cavity from being impacted by excessive flow velocity. The staggered arrangement in a plum blossom shape can avoid eddy disturbance caused by direct liquid impact. The rounded corners of the holes further reduce the resistance and disturbance risk when the liquid flows through. The synergistic effect of these three factors ensures the smooth flow of each phase liquid and maximizes the protection of the clarity of the layered interface, effectively solving the problems of layering chaos and low separation accuracy caused by traditional fixed aperture and disordered arrangement of guide holes.

[0022] Please see Figure 2A further solution based on this embodiment is as follows: two sets of flow guide baffles 27 divide the inner cavity of the separator body 1 into upper, middle, and lower chambers, thereby adapting to the extraction and separation of three-phase liquids. Furthermore, three sets of observation windows 22 are provided, distributed sequentially from top to bottom in the upper, middle, and lower chambers of the separator body 1. This structural design, using two sets of flow guide baffles 27 to divide the upper, middle, and lower chambers, precisely adapts to the separation requirements of three-phase extracts such as volatile oil-water-ethanol, ensuring that each chamber corresponds to one type of phase liquid. The retention and export mechanism enables "partitioned storage and independent export" of multiphase liquids, avoiding cross-mixing between phases. At the same time, the three sets of observation windows 22 correspond one-to-one with the three chambers, allowing operators to monitor the layering status and phase interface position in each chamber in real time through the observation windows 22, keep track of the liquid separation progress, and avoid phase mixing problems caused by blind export. Compared with the single-chamber single observation window 22 design, it significantly improves the accuracy and controllability of liquid separation operation, meeting the refined needs of multiphase separation in laboratories and small-scale production.

[0023] Please see Figure 4 A further solution based on this embodiment is as follows: the installation component includes limiting blocks 31 fixedly connected to both sides of the top cover 21 and a first elastic locking block 32 fixedly connected to the limiting blocks 31. The limiting blocks 31 are disposed on the main body 1 of the separatory tank, and the first elastic locking block 32 is engaged with the main body 1 of the separatory tank when the flow guide baffle 27 is installed. By designing the installation component consisting of the limiting blocks 31 and the first elastic locking block 32, the limiting blocks 31 can provide precise positioning for the installation of the flow guide baffle 27, avoiding the cavity from being poorly sealed or the liquid from being misaligned during the installation process. When the flow of liquid is obstructed, the first elastic locking block 32 uses its own elasticity to quickly lock and fix the flow guide baffle 27 to the main body 1 of the separator, without relying on bolts or other additional fastening tools. This simplifies the installation process of the flow guide baffle 27, reduces the difficulty of operation, and ensures the stability after installation. At the same time, with its detachable feature, the number of flow guide baffles 27 can be flexibly increased or decreased according to the number of liquid phases extracted (such as removing a set of baffles when separating two phases), which greatly improves the adaptability of the device to different separation requirements and solves the limitation of traditional fixed-installation baffles that cannot be flexibly adjusted.

[0024] The mounting components can also adopt other structures in the prior art, replacing the first elastic block 32 with a pin. The advantage is that the pin structure is simple and reliable. By inserting and fixing it to the corresponding insertion hole of the liquid separator body 1, the connection stability between the flow guide baffle 27 and the liquid separator body 1 can be further improved, avoiding the loosening of the baffle due to fatigue failure of the elastic block during long-term use.

[0025] Please see Figure 4A further solution based on this embodiment is as follows: The main body 1 of the separating tank has an installation groove at the corresponding position of the limiting block 31. When installing the flow guide baffle 27, the limiting block 31 slides into the installation groove of the main body 1 of the separating tank. The main body 1 of the separating tank also has a slot at the corresponding position of the first elastic locking block 32. When installing the flow guide baffle 27, the first elastic locking block 32 engages with the slot of the main body 1 of the separating tank. Through the matching design of the installation groove and the slot, the limiting block 31 slides along the installation groove to guide the installation of the flow guide baffle 27, ensuring the baffle... The precision of the plate installation position avoids gaps in the cavity or liquid leakage caused by installation deviation. The locking cooperation between the slot and the first elastic locking block 32 further enhances the fixing effect after installation, preventing the guide baffle 27 from loosening or shifting due to liquid impact during device operation. At the same time, the combination of sliding installation and locking fixation ensures the stability of the structure while retaining the convenience of disassembly, making subsequent baffle cleaning, replacement or quantity adjustment operations more efficient, effectively improving the maintenance convenience and service life of the device.

[0026] Please see Figure 5 A further solution based on this embodiment is as follows: the anti-clogging component includes an arc-shaped baffle plate 41 detachably installed on the top of the flow guide baffle 27, a support protrusion 42 fixedly connected to the bottom of the arc-shaped baffle plate 41, and a second elastic locking block 43 fixedly connected to the support protrusion 42. The second elastic locking block 43 is engaged with the flow guide baffle 27 when the arc-shaped baffle plate 41 is installed. The arc-shaped baffle plate 41 prevents residue from entering the flow guide hole of the flow guide baffle 27, while the liquid can flow smoothly into the flow guide hole through the 5mm gap between the arc-shaped baffle plate 41 and the inner wall of the liquid separator body 1. By designing the anti-clogging component consisting of the arc-shaped baffle plate 41, the support protrusion 42, and the second elastic locking block 43, the arc-shaped baffle plate 41... 1. It can accurately block plant residues mixed in the extract from entering the guide hole, thus preventing the guide hole from becoming clogged at the source. The supporting protrusion 42 forms a fixed gap of 5mm between the arc-shaped slag baffle 41 and the inner wall of the main body 1 of the separator. This gap ensures smooth flow of liquid (without affecting separation efficiency) and effectively intercepts fine residues (particle size greater than 1mm). The second elastic locking block 43 enables quick and detachable locking between the arc-shaped slag baffle 41 and the guide baffle 27, which is convenient for subsequent cleaning, maintenance or replacement. Compared with the traditional non-slag baffle structure or fixed slag baffle structure, this component not only solves the problem of device shutdown caused by guide hole blockage, but also takes into account the ease of operation and ensures the continuity and stability of the separation process.

[0027] The anti-clogging component can also adopt other structures in the existing technology, replacing the second elastic block 43 with bolts. The advantage is that the bolt connection is more secure, which can make the arc-shaped slag baffle 41 and the flow guide baffle 27 form a tight fit and fixation effect, avoiding the displacement of the slag baffle due to liquid impact during the liquid separation process, and ensuring the stability of the 5mm flow gap.

[0028] Please see Figure 1 A further solution based on this embodiment is as follows: the extraction and separation assembly includes an inlet 51 fixedly connected to the top cover 21 at one end, a drain pipe 54 fixedly connected to the bottom of the separation tank body 1 at one end, a second one-way valve 55 fixedly connected to the drain pipe 54, three sets of guide pipes 52 fixedly connected to the upper, middle, and lower chambers of the separation tank body 1 at one end, and a first one-way valve 53 fixedly connected to the guide pipes 52. Through the design of the extraction and separation assembly consisting of the inlet 51, drain pipe 54, three sets of guide pipes 52, and corresponding one-way valves, the inlet 51 provides a stable injection channel for the mixed extract, achieving uniform feeding in conjunction with the conical distributor 24. The three sets of guide pipes 52 connect with the upper, middle, and lower chambers of the separation tank body 1. The three lower chambers correspond one-to-one, enabling independent and precise discharge of each phase liquid, avoiding cross-mixing during the discharge process. The first one-way valve 53 and the second one-way valve 55 respectively prevent backflow of liquid in the guide pipe 52 and backflow of residue and liquid in the drain pipe 54, ensuring the unidirectionality and stability of the liquid separation process. The drain pipe 54 facilitates the periodic discharge of residue accumulated at the bottom of the tank, preventing long-term accumulation of residue from affecting the operation of the device. The entire component realizes a closed-loop design of the entire process of "feeding-liquid separation-discharge-drainage", which not only improves the recovery rate and purity of the target phase liquid, but also simplifies the subsequent cleaning and maintenance of the device. Compared with the traditional single discharge channel design, it significantly improves the efficiency and convenience of liquid separation operation.

[0029] Working principle: First, based on the required number of phases in the extractant, the limiting block 31 of the installation component guides and engages with the mounting groove of the main body 1 of the separator. When extracting the three-phase extractant, the two sets of flow guide baffles 27 are slid into the installation position from top to bottom. Precise positioning is achieved by the engagement and fixation of the first elastic locking block 32 with the locking groove. At the same time, the second elastic locking block 43 of the anti-clogging component detachably installs the arc-shaped slag baffle 41 on the top of each set of flow guide baffles 27. The supporting protrusion 42 ensures that the arc-shaped slag baffle... 41 forms a 5mm fixed gap with the inner wall of the main body 1 of the separator, and then the conical distributor 24 is firmly installed on the top cover 21 by screw 25 and self-locking nut 26; then the first one-way valve 53 of all guide pipes 52 and the second one-way valve 55 of drain pipe 54 are closed, and the mixed extract is injected through the feed port 51 of the extraction and separation assembly. The liquid is dispersed by the conical distributor 24 to avoid disturbing the initial mixture. During the feeding process, the gas accumulated in the tank is released through the exhaust port 23 on the top cover 21. Timely discharge prevents obstruction of liquid flow; after the extract enters the main body 1 of the separatory tank, it gradually separates into upper, middle and lower chambers divided by two sets of flow guide baffles 27. The 8mm staggered flow guide holes on the upper flow guide baffle 27 are adapted to the rapid sinking of the heavy phase liquid, while the 4mm similar flow guide holes on the lower flow guide baffle 27 slow down the flow rate of the heavy phase to protect the phase interface. The rounded corners of the holes further reduce liquid disturbance. The operator monitors the separation status and phase interface position in real time through the observation windows 22 corresponding to the three chambers. After the separation is completed, the first one-way valve 53 on the corresponding flow guide pipe 52 of each chamber is opened in sequence to realize the independent and precise discharge of each phase liquid. The one-way valve effectively prevents liquid backflow. After the separation is completed, the residue at the bottom of the tank is discharged through the drain pipe 54 and the second one-way valve 55. The small residue intercepted by the arc-shaped slag baffle 41 can be removed by disassembling the second elastic block 43 to clean it. The whole process achieves stable stratification, precise separation and convenient maintenance of multiphase extract through the synergistic action of various components.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
