Description

Technical Field

[0001] This utility model mainly relates to the field of plant extraction technology, specifically a plant extraction filtration device. Background Technology

[0002] In the plant extraction process, filtration is the core step to achieve solid-liquid separation of plant raw materials and obtain the target effective components. Its effectiveness and efficiency are directly related to the purity, yield and smoothness of the production process of the extract.

[0003] Current mainstream plant extraction filtration devices mostly rely on fixed filter tanks or plates for solid-liquid separation. However, plant materials (especially root and stem plants and fibrous materials) contain a large amount of fine fibers, starch particles, and mucilage, which easily adhere to the surface of the filter pores or become embedded inside them during filtration, leading to pore blockage. Existing devices generally lack dedicated automated cleaning structures for handling pore blockage, relying on manual cleaning: when pore blockage causes a significant decrease in filtrate flow rate, the feeding and filtration process must be paused, and operators must open the filter box door, manually disassemble the filter tank or plate, and then use brushes, scrapers, and other tools to remove the blockage impurities from the surface and interior of the filter pores; some complex devices even require disassembling the filter components for cleaning. This manual cleaning method has several drawbacks: firstly, the cleaning operation is cumbersome and time-consuming; secondly, the filter box is open during cleaning, allowing outside air, dust, and contaminants from the operator's hands to easily enter the filtration area, contaminating the extract and affecting product purity; and thirdly, frequent manual intervention increases the labor intensity of operators, making it difficult to meet the efficiency requirements of large-scale production.

[0019] Please refer to the appendix carefully. Figure 1-4 A plant extraction filtration device, wherein a filter tank 2 is fixedly installed inside the filter box 1, the filter box 1 is provided with an inlet on the upper side of the filter tank 2, the filter box 1 is provided with an outlet on the lower side of the filter tank 2, and valves matching them are installed inside the inlet and outlet. The filter box 1 is provided with an observation window to facilitate the observation of the filtration status of the filter tank 2.

[0020] Inside the filter box 1, a scraper mechanism 3 is provided on the inner side of the filter tank 2. The scraper mechanism 3 includes a rotating rod 4, and scraper assemblies 5 for cleaning the filter tank 2 are symmetrically arranged on the outer side of the rotating rod 4.

[0021] One end of the rotating rod 4 is connected to the disc 41 set on the outside of the filter box 1. The filter box 1 has a through groove for the rotating rod 4 to pass through. The disc 41 is rotatably connected to the fixed frame installed on the top of the filter box 1. A drive motor 42 for driving the disc 41 to rotate is set on one side of the fixed frame. A circular mounting groove is reserved on the side of the fixed frame facing the disc 41, and a high-precision deep groove ball bearing is embedded in the groove.

[0022] The filter tank 2 is connected to the inner wall of the filter box 1 via an annular sealing plate 7. The filter tank 2 includes a conical cylinder 21. The inner wall of the conical cylinder 21 is mirror-polished to reduce the adhesion of fibrous residues to the wall surface. The conical cylinder 21 is designed so that the residues slide down naturally under gravity. An annular filter plate 22 is fixedly installed on the top of the conical cylinder 21. A matching sealing door 23 is installed inside the discharge port of the conical cylinder 21. The sealing door 23 can be automatically closed by a door closing spring hinge. A collection cylinder for collecting impurities is installed at the bottom of the conical cylinder 21 below the discharge port. The bottom end of the collection cylinder is located outside the filter box 1, and a discharge port is provided at the bottom end of the collection cylinder. The door closing spring hinge used in this application is a mature existing technology. The closing strength of the door closing spring hinge is selected according to actual needs. Therefore, the components are not described in detail here.

[0023] The scraper assembly 5 includes a drive member 51, which can drive the scraper 52 to move. The drive member 51 is slidably connected to the mounting cylinder 53, and the mounting cylinder 53 is fixedly connected to the rotating rod 4. A round-headed push rod 54 that pushes the drive member 51 to move is installed on the other side of the drive member 51. One end of the round-headed push rod 54 is located inside the rotating rod 4, and a guide hole is provided on the mounting cylinder 53 to guide the movement of the round-headed push rod 54. A reset spring is provided inside the mounting cylinder 53 to drive the drive member 51 to reset.

[0024] The rotating rod 4 is equipped with a telescopic top block 6 that drives the round-headed top rod 54 to move. The telescopic top block 6 includes a top block 61. One end of the top block 61 is provided with an arc-shaped drive boss that works with the round-headed top rod 54. The top block 61 moves inside the rotating rod 4 under the action of the electric push rod 62. The rotating rod 4 is provided with heat dissipation holes that work with the electric push rod 62. A rotary sealing joint is installed at the end of the rotating rod 4 near the disc 41. The power cord of the electric push rod 62 passes through the central hole of the rotary sealing joint and is led out to the outside of the filter box 1 to prevent the power cord from getting tangled when the rotating rod 4 rotates. A sealing door top rod 63 is provided at the end of the top block 61, and the sealing door top rod 63 can push open the sealing door 23 to discharge the material.

[0025] The specific operating procedure of this utility is as follows: the material is injected into the filter box 1 through the feed port. After the material falls onto the filter tank 2, the liquid in the material is discharged from the discharge port through the annular filter plate 22.

[0026] When the flow rate of the filtrate in the filter tank 2 decreases and it is necessary to clean the blockage in the filter tank 2, the electric push rod 62 inside the rotating rod 4 is activated by the controller. The telescopic shaft of the electric push rod 62 pushes the top block 61 to move along the inside of the rotating rod 4. The arc-shaped drive boss on one side of the top block 61 pushes the round-headed push rod 54, causing the round-headed push rod 54 to extend outward along the guide hole, thereby pushing the drive component 51 to slide in the mounting cylinder 53, and finally driving the scraper 52 to extend and adhere to the surface of the annular filter plate 22.

[0027] At the same time, the sealing door push rod 63 at the end of the top block 61 passes through the through hole at the end of the rotating rod 4 and pushes the sealing door 23 at the discharge port of the conical cylinder 21, overcoming the elastic force of the closing spring hinge to open the sealing door 23.

[0028] The scraper 52 rotates continuously with the rotating rod 4, scraping off the blockage residue on the surface of the annular filter plate 22. The residue slides down the inner wall of the conical cylinder 21 under the action of gravity and falls into the collection cylinder below through the opened sealing door 23.

[0029] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
