Description

Technical Field

[0001] This application relates to the field of extract filtration technology, specifically a multi-layer filtration device for plant extraction. Background Technology

[0002] Plant extracts are natural nutrients or colors extracted from various plants. They are usually obtained by extracting from plant leaves, stems, flowers, seeds, etc. Extraction methods include steaming extraction, alcohol extraction, and glycerol extraction.

[0003] According to Chinese patent publication number CN218421287U, a plant extract filtration device is described. After filtering the plant extract, the device installs a fixing frame, then rotates a screw to move it downwards, thereby causing the pressure plate to move downwards and squeeze the plant fibers or impurities on the filter plate. This squeezes out the adhering extract, making the separation more thorough and reducing waste.

[0004] This solution has the following drawbacks:

[0005] During the pressing process, impurities may accumulate on the side of the plater closest to the filter screen. When these impurities accumulate excessively, the surface of the plater will become uneven, and the residual impurities will provide nutrients and an environment for the growth of microorganisms. Under suitable conditions, microorganisms will multiply in large numbers, not only contaminating the extract but also potentially producing odors and harmful substances, causing the extract to deteriorate and become unusable, resulting in economic losses.

[0006] Therefore, this application provides a multi-layer filtration device for plant extraction to solve the above-mentioned problems. Utility Model Content

[0007] This application provides a multi-layer filtration device for plant extraction, which aims to solve the problem mentioned in the background art that the side of the pressure plate near the filter screen will be covered with impurities during the pressing process, and when these impurities accumulate too much, it will cause the surface of the pressure plate to be uneven and bacteria to grow.

[0008] To achieve the above objectives, this application provides the following technical solution: a multi-layer filtration device for plant extraction, comprising a housing and a fixed frame detachably mounted on the housing, a screw rotatably connected to the fixed frame, a pressure plate aligned with the opening at the top of the housing being fixedly mounted at the lower end of the screw, and a filter plate being disposed inside the housing;

[0009] The fixing frame is equipped with a cleaning mechanism for cleaning impurities on the surface of the pressure plate;

[0010] The impurity removal mechanism includes movable rails symmetrically mounted on a fixed frame and a collection tray connected to the movable rails. The ends of the two movable rails away from the fixed frame are fixedly connected by a reinforcing frame. A movable shaft is rotatably connected to the center of the collection tray. A scraper is fixedly mounted on the upper end of the movable shaft. A cleaning cloth seat is detachably mounted on the upper end of the scraper. A second servo motor is mounted on the lower end of the collection tray. The output end of the second servo motor is fixedly connected to the lower end of the movable shaft.

[0011] Preferably, the cross-section of the scraper and the cleaning cloth seat is conical, which optimizes the adaptability of the cleaning structure, solves the problem of blind spots in cleaning impurities at the edge of the pressure plate, and improves the thoroughness of cleaning.

[0012] Preferably, the upper end of the scraper is provided with a magnetic mounting groove, and limit blocks are symmetrically installed at the magnetic mounting groove. The cleaning cloth seat is symmetrically provided with limit grooves for fitting the limit blocks, thereby improving the replacement efficiency of the cleaning cloth seat and ensuring the stability of the cleaning effect.

[0013] Preferably, the magnetic mounting groove is provided with a magnetic surface, and the lower end of the cleaning cloth seat is provided with a metal sheet that is magnetically fixed to the magnetic mounting groove.

[0014] Preferably, a first servo motor is mounted on the fixed frame, and sliders are symmetrically mounted on the outer side of the collection tray. The sliders are slidably connected to the interior of the movable rail frame. A threaded screw is rotatably connected inside the movable rail frame on the side closer to the first servo motor, and the threaded screw is threadedly inserted into the nearby slider. The output end of the first servo motor is fixedly connected to the threaded screw. A guide rod is fixedly mounted inside the movable rail frame on the side away from the first servo motor, and the guide rod is inserted into the nearby slider.

[0015] Preferably, a limiting plate for limiting the upward movement of the pressure plate is installed on the inner side of the fixing frame.

[0016] In this filtration device, the second servo motor drives the movable shaft to rotate, which in turn drives the scraper and cleaning cloth seat to rotate and clean the impurities on the surface of the pressure plate. During the impurity removal process, the collection tray and the bottom of the pressure plate are in a closed state, and the scraped impurities will fall into the inside of the collection tray, which solves the problem that excessive accumulation of impurities will cause unevenness on the surface of the pressure plate and the growth of bacteria.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a multi-layer filtration device for plant extraction, such as... Figure 1-5 As shown, the filter device includes a housing 1 and a fixing frame 2 detachably mounted on the housing 1. A screw 3 is rotatably connected to the fixing frame 2. A pressure plate 4 aligned with the top opening of the housing 1 is fixedly mounted on the lower end of the screw 3. A filter plate 11 is provided inside the housing 1.

[0026] The fixed frame 2 is equipped with a cleaning mechanism 5 for cleaning impurities on the surface of the pressure plate 4;

[0027] The impurity removal mechanism 5 includes movable rail frames 51 symmetrically mounted on the fixed frame 2 and a collection tray 54 connected to the movable rail frames 51. The ends of the two movable rail frames 51 away from the fixed frame 2 are fixedly connected by a reinforcing frame 52. A movable shaft 56 is rotatably connected at the center of the collection tray 54. A scraper 57 is fixedly mounted on the upper end of the movable shaft 56. A cleaning cloth seat 58 is detachably mounted on the upper end of the scraper 57. A second servo motor 59 is mounted on the lower end of the collection tray 54. The output end of the second servo motor 59 is fixedly connected to the lower end of the movable shaft 56.

[0028] Specifically, the shell 1 serves as a container for filtering and collecting the extract, and the fixed frame 2 provides installation support for the screw 3 and the pressure plate 4. The rotation of the screw 3 drives the pressure plate 4 to rise and fall, thereby squeezing and filtering the material inside the shell 1. The impurity removal mechanism 5 is constructed with a movable base through the movable rail frame 51 and the reinforcing frame 52. When the pressure plate 4 moves to the predetermined impurity removal position, the second servo motor 59 drives the movable shaft 56 to rotate, which in turn drives the scraper 57 and the cleaning cloth seat 58 to rotate, cleaning the impurities on the surface of the pressure plate 4. During the impurity removal process, the collection tray 54 and the bottom of the pressure plate 4 are in a closed state, and the scraped impurities will fall into the inside of the collection tray 54, waiting for subsequent personnel to clean them up.

[0029] The cross-sections of the scraper 57 and the cleaning cloth seat 58 are conical.

[0030] More specifically, the conical cross-section of the scraper 57 and the cleaning cloth seat 58 makes it easier to fit the surface of the pressure plate 4 during rotation cleaning. The gradual angle of the conical surface enhances the scraping and wiping effect of impurities. The taper of the cleaning cloth seat 58 matches that of the scraper 57 and is made of microfiber material.

[0031] The upper end of the scraper 57 is provided with a magnetic mounting groove 571, and limit blocks 572 are symmetrically installed at the magnetic mounting groove 571. The cleaning cloth seat 58 is symmetrically provided with limit grooves 581 for fitting the limit blocks 572. The magnetic mounting groove 571 is provided with a magnetic surface, and the lower end of the cleaning cloth seat 58 is provided with a metal sheet that is magnetically fixed to the magnetic mounting groove 571.

[0032] Furthermore, the magnetic mounting groove 571 and the limiting block 572 of the scraper 57 cooperate with the limiting groove 581 of the cleaning cloth seat 58 to achieve quick disassembly and assembly of the cleaning cloth seat 58 through mechanical limiting and magnetic fixation, which is convenient for replacement and cleaning. During the cleaning process, the scraper 57 and the cleaning cloth seat 58 are in complete contact with the surface of the pressure plate 4. Therefore, there is no need to worry about the cleaning cloth seat 58 falling off during rotation. The magnetic surface of the magnetic mounting groove 571 is made of neodymium iron boron magnet, the magnetic surface is covered with a wear-resistant coating, the metal sheet is iron-nickel alloy, and the surface is galvanized.

[0033] A first servo motor 53 is installed on the fixed frame 2. Slider 55s are symmetrically installed on the outer side of the collection tray 54. The slider 55 is slidably connected to the inside of the movable rail frame 51. A threaded screw is rotatably connected inside the movable rail frame 51 on the side closer to the first servo motor 53. The threaded screw is threadedly inserted into the nearby slider 55. The output end of the first servo motor 53 is fixedly connected to the threaded screw. A guide rod is fixedly installed inside the movable rail frame 51 on the side away from the first servo motor 53. The guide rod is inserted into the nearby slider 55.

[0034] It should be noted that the first servo motor 53 drives the screw rod inside the movable rail frame 51 to rotate, which in turn drives the slider 55 to slide along the rail frame, so as to move the impurity removal components such as the collection plate 54 and scraper 57 horizontally to the predetermined position. The guide rod assists the slider 55 to slide and prevents deflection. By enabling the impurity removal mechanism 5 to have a position adjustment function, it can be moved to the standby position when the pressure plate 4 is in the working state, so as to facilitate the cleaning of the impurity removal mechanism 5 by the staff and improve the versatility of the device. The first servo motor 53 is connected through a PLC control system.

[0035] A limiting plate 6 for limiting the upward movement of the pressure plate 4 is installed on the inner side of the fixing frame 2.

[0036] It is worth mentioning that the limiting plate 6 is installed inside the fixed frame 2. When the pressure plate 4 rises to the preset height, it restricts the pressure plate 4 from rising further, and the pressure plate 4 is at the predetermined cleaning height when it contacts the limiting plate 6.

[0037] In use, when the pressure plate 4 rises to the preset height, it is restricted from rising further. The first servo motor 53 drives the threaded screw in the movable rail frame 51 to rotate, causing the slider 55 to slide along the rail frame, so that the collection plate 54, scraper 57 and other impurity removal components are moved horizontally to the predetermined position. The second servo motor 59 drives the movable shaft 56 to rotate, causing the scraper 57 and cleaning cloth seat 58 to rotate, cleaning the impurities on the surface of the pressure plate 4. During the impurity removal process, the bottom of the collection plate 54 and the pressure plate 4 are in a closed state, and the scraped impurities will fall into the inside of the collection plate 54. After the impurity removal process is completed, the second servo motor 59 drives the collection plate 54 to move to the waiting position, so that the staff can clean the impurity removal mechanism 5.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
