Description

Technical Field

[0001] This utility model relates to the field of extraction technology, and in particular to a purification device for plant extraction. Background Technology

[0002] The active ingredients of natural plants, such as flavonoids, alkaloids and polysaccharides, are often obtained by distillation extraction. The steam is condensed to form an extract, which is then purified using molecular-level technologies such as membrane separation to remove impurities and refine the active ingredients.

[0003] A search revealed that patent CN222694010U discloses a device for extracting effective components from natural plants based on membrane separation. This device utilizes a double-ended lead screw and a support plate, allowing for easy assembly and disassembly of the end caps via the lifting and lowering of the support plate. This design changes the traditional connection method between the membrane separator's outer shell and the end caps, improving the ease of assembly and disassembly of the membrane separator, increasing the efficiency of microporous membrane assembly and disassembly, and ensuring the extraction efficiency of effective components from natural plants.

[0004] However, the aforementioned device has the following drawbacks: During the replacement of the microporous filter membrane, current operations require the simultaneous replacement of all three membranes; they cannot be replaced sequentially to achieve continuous operation without shutdown. However, a complete replacement necessitates a shutdown, impacting continuous equipment use. Furthermore, the end caps are fixedly connected to external pipelines, which are typically rigid metal pipes. This necessitates disassembling these external connections when raising or lowering the end caps, making the operation cumbersome and further increasing maintenance complexity. Therefore, further improvements are needed. To this end, we propose a plant extractor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a purification device for plant extraction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plant extractor, comprising a collection box and a booster pump fixedly connected to the top of the collection box, three upper solenoid valves fixedly connected to the bottom of the collection box, a bent pipe fixedly connected to the bottom of each of the three upper solenoid valves, a movable pipe sealed and slidably sleeved on the outer surface of each of the three bent pipes, and an end cap fixedly connected to the bottom of each of the three movable pipes.

[0007] The bottom of the collection box is fixedly connected to a support frame, and the inner walls on both sides of the support frame are fixedly connected to an installation frame. The bent pipe is fixedly connected to the installation frame, and the three end caps are all mounted with screw-type lifting components together with the installation frame.

[0008] The bottom of each of the three end caps is sealed and pressed with a cylindrical body, and the top of the cylindrical body is sealed and mounted with a filter element, and the end cap is sealed and pressed onto the top of the filter element.

[0009] A rotating pipe is installed at the bottom of each of the three cylinders and between it and the mounting bracket. A lower solenoid valve is fixedly connected to the bottom of each of the three rotating pipes.

[0010] Furthermore, a condenser connecting pipe is fixedly connected to one side of the top of the collection box.

[0011] Furthermore, each of the three end caps has a pressure ring fixedly connected to its inner surface, which facilitates the sealing and pressing of the filter element.

[0012] Furthermore, all three screw-type lifting assemblies include a handle, which is positioned above the mounting frame. A drive gear is fixedly connected to the bottom of the handle and is rotatably connected to the mounting frame. Driven gears are meshed on both sides of the outer surface of the drive gear. Screws are fixedly connected to the bottom of both driven gears, and the screws pass through the mounting frame and are rotatably connected to it. A slider is threaded onto the outer surface of both screws, and the slider is fixedly connected to the end cover, which can drive the end cover to rise and fall stably.

[0013] Furthermore, all three filter elements include a skeleton, which is sealed and mounted on the top step of the cylinder and abuts against the pressure ring. A microporous filter membrane is fixedly connected to the inner surface of the skeleton, and the skeleton can increase the strength of the microporous filter membrane.

[0014] Furthermore, all three rotating pipe fittings include Z-shaped pipes, and the Z-shaped pipes are fixedly interconnected at the bottom of the cylinder. The bottom of the Z-shaped pipes is fixedly interconnected with a rotary joint, and the fixed end of the rotary joint is fixedly connected to the mounting bracket and fixedly interconnected with the lower solenoid valve. The rotary joint can prevent the rotation of the Z-shaped pipe from affecting the connection with the lower solenoid valve.

[0015] The beneficial effects of this utility model are:

[0016] In use, this utility model sets up three independent parallel filter units, each controlled by an upper solenoid valve. Each unit has a unique screw-type lifting assembly to drive the end cover to separate from the cylinder. At the same time, a rotating pipe is used to connect the cylinder to a fixed lower pipe. This solves the problem in the prior art that the entire machine must be stopped to replace the filter element and the external metal rigid pipe must be disassembled. It realizes the rapid and independent online replacement and maintenance of a single filter element, which greatly improves the continuity of equipment use and the convenience of maintenance operations.

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, a plant extractor is disclosed, comprising a collection tank 1 and a booster pump 2 fixedly connected to the top of the collection tank 1. The booster pump 2 can increase the pressure inside the collection tank 1. A condenser connecting pipe 3 is fixedly connected to one side of the top of the collection tank 1. The condenser connecting pipe 3 can be connected to an external condenser for collecting the distilled and condensed liquid.

[0026] Three upper solenoid valves 11 are fixedly connected to the bottom of the collection box 1. Each of the three upper solenoid valves 11 is fixedly connected to a bend 10. The outer surface of each of the three bends 10 is sealed and slidably fitted with a movable tube 9. A sealing ring is fixedly fitted to the outer surface of the bend 10, and the sealing ring abuts against the outer wall of the movable tube 9 to achieve a seal between the movable tube 9 and the bend 10. The bottom of each of the three movable tubes 9 is fixedly connected to an end cap 13. In actual use, a pressure relief valve can be installed on the end cap 13 as needed for inclined pressure when replacing the filter element. The inner surface of each of the three end caps 13 is fixedly connected to a pressure ring 19. The pressure ring 19 and the end cap 13 are designed as an integral piece, reducing processing steps and ensuring connection strength. At the same time, the pressure ring 19 matches the top step of the cylinder 5 and has a limiting and positioning function.

[0027] A support frame 7 is fixedly connected to the bottom of the collection box 1. A mounting frame 4 is fixedly connected to the inner walls of both sides of the support frame 7. The bent pipe 10 is fixedly connected to the mounting frame 4. Each of the three end caps 13 is mounted with a screw-type lifting assembly along with the mounting frame 4. Each of the three screw-type lifting assemblies includes a handle 18, which is positioned above the mounting frame 4. A drive gear 17 is fixedly connected to the bottom of the handle 18, and the drive gear 17 is rotatably connected to the mounting frame 4. Driven gears 12 are meshed on both sides of the outer surface of the drive gear 17. Screws are fixedly connected to the bottom of each of the two driven gears 12. 8. The screw 8 passes through the mounting bracket 4 and is rotatably connected to the mounting bracket 4. The outer surfaces of the two screws 8 are threaded with sliders 14, and the sliders 14 are fixedly connected to the end cover 13. The mounting shaft of the drive gear 17 and the two screws 8 are rotatably connected to the mounting bracket 4 through bearing seats. The bearing seat body is fixed to the mounting bracket 4. The inner rings of the bearings built into the three bearing seats are respectively fixedly sleeved on the mounting shaft of the drive gear 17 and the outer surfaces of the two screws 8. The thread helix angle of the screw 8 is less than the friction angle, so that the screw 8 has a self-locking ability and can avoid displacement due to vibration or load.

[0028] The bottom of each of the three end caps 13 is sealed and pressed with a cylinder 5. The top of the cylinder 5 is sealed and mounted with a filter element, and the end caps 13 are sealed and pressed onto the top of the filter element. Each of the three filter elements includes a skeleton 21, and the skeleton 21 is sealed and mounted at the top step of the cylinder 5 and seals against the pressure ring 19. A microporous filter membrane 20 is fixedly connected to the inner surface of the skeleton 21. The skeleton 21 can increase the strength of the microporous filter membrane 20 and ensure its performance. The top and bottom of the mounting ring of the skeleton 21 are fixedly connected with annular sealing gaskets to ensure the sealing between the skeleton 21 and the pressure ring 19 and the step of the cylinder 5.

[0029] Rotary pipe fittings are installed at the bottom of each of the three cylinders 5 and the mounting bracket 4. The bottom of each of the three rotating pipe fittings is fixedly connected to a lower solenoid valve 16. Each of the three rotating pipe fittings includes a Z-shaped pipe 6, which is fixedly connected to the bottom of the cylinder 5. A rotary joint 15 is fixedly connected to the bottom of the Z-shaped pipe 6, and the fixed end of the rotary joint 15 is fixedly connected to the mounting bracket 4 and fixedly connected to the lower solenoid valve 16. The rotary joint 15 is a 360° rotating sealed rotary connector for conveying fluid media, used to transfer fluid media between stationary pipes and rotating equipment.

[0030] Working principle: The crude plant extract first enters the collection tank 1 through the condenser connecting pipe 3. After being pressurized by the booster pump 2, it forms a high-pressure extract. The high-pressure extract then enters the filtration chamber composed of the end cap 13 and the cylinder 5 through three parallel pipes controlled by the upper solenoid valve 11, the bend 10, and the movable pipe 9. Under pressure, the extract penetrates the microporous filter membrane 20 of the filter element. The small molecule effective components, as the filtrate, pass through the membrane and enter the lower part of the cylinder 5, and are then discharged and collected through the Z-shaped pipe 6, the rotary joint 15, and the lower solenoid valve 16; while large molecule impurities are retained to form a concentrated liquid.

[0031] When a single filter element becomes clogged, it can be replaced using the unit's independent screw-type lifting assembly: the corresponding upper solenoid valve 11 and lower solenoid valve 16 are closed, and then the handle 18 drives the drive gear 17, which in turn drives the two driven gears 12 to rotate, causing the screw 8 to rotate and drive the slider 14 to lift the end cover 13, thereby releasing the clamping force on the filter element frame 21. Then, the cylinder 5 is rotated. The design of the rotary joint 15 allows the cylinder 5 to maintain a sealed connection with the bottom lower solenoid valve 16 during rotation, without the need to disassemble rigid pipe components such as the lower solenoid valve 16. The filter element is then pulled out for replacement. After replacement, all components are reset.

[0032] In actual use, a controller can be installed. The controller is electrically connected to the booster pump 2, the upper solenoid valve 11, and the lower solenoid valve 16, which is conducive to controlling the overall operation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
