[0015] 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. Example

[0016] like Figures 1-4 As shown; An extraction device for the production of γ-aminobutyric acid includes a base 1, an extraction tank 2, and a filter box 9. The extraction tank 2 and the filter box 9 are fixed on the base 1. The top of the extraction tank 2 is provided with a sealing cover 3, and the sealing cover 3 is provided with a feed pipe 4 and a drive motor 5. A liquid pump 8 is installed between the extraction tank 2 and the filter box 9. The filter box 9 is provided with a first filter plate 10 and a second filter plate 11. A lifting rod 12 is fixed above the first filter plate 10 and the second filter plate 11. A pusher scraper 15 is installed at one end of the filter box 9, and a hydraulic telescopic rod 16 is connected to one end of the pusher scraper 15.

[0017] In this implementation scheme, by setting up a multi-stage filtration structure consisting of a first filter plate 10 and a second filter plate 11, solid impurities can be graded and intercepted, avoiding the clogging problem caused by excessive instantaneous load on a single filter plate, and significantly improving filtration efficiency. The push scraper 15 driven by the hydraulic telescopic rod 16 can automatically and thoroughly push the residue accumulated at the bottom of the filter box 9 forward and discharge it through the detachable sealing plate 14, effectively preventing cross-contamination between different batches of materials.

[0018] In an optional embodiment, the output end of the drive motor 5 is connected to a stirring shaft 6 that extends into the extraction tank 2, and a plurality of stirring blades 7 are fixed on the stirring shaft 6.

[0019] In this embodiment, the arrangement of the stirring blades 7 can generate strong eddies and shear forces, so that the extraction solvent and the material solution are fully and uniformly mixed in the extraction tank 2, which greatly increases the contact area between the two phases, thereby significantly improving the extraction rate and extraction efficiency of γ-aminobutyric acid.

[0020] In an optional embodiment, the extraction tank 2 and the filter box 9 are interconnected via a connecting pipe.

[0021] In this implementation scheme: the liquid pump 8 is installed on the connecting pipe, which directly connects the extraction tank 2 and the filter box 9, forming a continuous and integrated extraction-filtration workflow. With the liquid pump 8, the extracted mixture can flow directly into the filtration unit by gravity or system pressure, avoiding the transfer and transportation steps required in the traditional process. This reduces material loss and possible external contamination, and simplifies the operation process.

[0022] In an optional embodiment, both the first filter plate 10 and the second filter plate 11 are perforated mesh structures, the first filter plate 10 and the second filter plate 11 are arranged in parallel, and the pore size decreases gradually from left to right.

[0023] In this implementation scheme, the design of double-layer filter plates with progressively smaller pore sizes constitutes a highly efficient multi-stage filtration system. The first filter plate 10 with a larger pore size intercepts most of the larger solid particles, preventing them from quickly clogging the subsequent filter pores. The second filter plate 11 with a smaller pore size is responsible for trapping finer impurities. This graded loading and step-by-step fine filtration method greatly alleviates the clogging pressure of a single-layer filter plate, significantly extends the filtration cycle, improves filtration efficiency, and ensures the clarity of the final filtrate.

[0024] In an optional embodiment, a discharge pipe 13 is fixed to one side of the filter box 9, and a removable sealing plate 14 is bolted to the front end of the filter box 9.

[0025] In this embodiment: the bolt-mounted removable plate 14 provides maximum access to the interior of the filter box 9. When large-scale cleaning, maintenance or replacement of internal components is required, it can be opened simply by removing the bolts. The discharge pipe 13 facilitates the collection and discharge of the filtered pure extract.

[0026] In an optional embodiment, the first filter plate 10 and the second filter plate 11 are fixed relative to each other by a lifting rod 12, and both the first filter plate 10 and the second filter plate 11 are detachably connected to the filter box 9.

[0027] In this implementation scheme: the lifting rod 12 connects the two-stage filter plates into a whole module, realizing the linkage of filter plate loading and unloading. The operator can easily lift the entire filter module from the filter box 9 by simply lifting the lifting rod 12, so that the filter plates can be thoroughly cleaned offline or quickly replaced.

[0028] In an optional embodiment, the push scraper 15 is matched to the internal dimensions of the filter box 9, and the push scraper 15 is driven by the hydraulic telescopic rod 16 to move horizontally along the box.

[0029] In this implementation scheme: the pusher scraper 15, which matches the inner wall size, ensures that all filter residues accumulated at the bottom of the filter box 9 can be scraped off without dead angles during its movement. The hydraulic telescopic rod 16, as the driving source, can provide strong, stable and controllable linear thrust, realize automated cleaning, effectively eliminate residues, prevent batch contamination, and significantly improve cleaning efficiency and operational safety.

[0030] Working principle: Feeding and extraction: The culture broth fermented by microorganisms such as lactic acid bacteria is pumped into or flows into the extraction tank 2 through the feed pipe 4. Then, an organic solvent that is immiscible with water is added into the extraction tank 2. The drive motor 5 is started, and the drive motor 5 drives the stirring shaft 6 and stirring blades 7 to rotate, so that the solvent and the material are fully mixed and the extraction efficiency is improved. Filtration and Separation: Start the liquid pump 8. The liquid pump 8 draws the mixture into the filter box 9 through the connecting pipe. After entering the filter box 9, the mixture is impacted and forced to flow upward. It passes through the first filter plate 10 and the second filter plate 11 in sequence, ensuring that all liquid is filtered by the filter plates and preventing impurities from settling directly to the bottom. Due to the special shape of the filter box 9, the liquid can continue to flow to the right and pass through the first filter plate 10 and the second filter plate 11 in sequence for two-stage filtration, effectively intercepting solid impurities and improving the purity of the filtrate. The filtered liquid is discharged through the discharge pipe 13 and enters the next process. The first filter plate 10 and the second filter plate 11 are sealed with a sealing strip or groove structure between them and the inner wall of the filter box 9 to ensure that there is no gap between the filter plate and the bottom of the box after installation, preventing impurities from wrapping around the filter plate. Filter plate cleaning and maintenance: When extraction is complete, stop the machine and clean the device. Lift the first filter plate 10 and the second filter plate 11 as a whole using the lifting rod 12 for cleaning or replacement. The removable plate 14 is fixed with bolts and can be removed to allow access to the filter box 9 for thorough cleaning. Impurity cleaning and discharge: After removing the removable sealing plate 14, start the hydraulic telescopic rod 16. The hydraulic telescopic rod 16 pushes the push scraper 15 to move along the bottom of the filter box 9, pushing the accumulated solid impurities to one side of the removable sealing plate 14. The bottom of the push scraper 15 is equipped with a flexible scraper to ensure close contact with the bottom of the filter box, thoroughly scraping away the deposits until the impurities are pushed out of the box, thus completing the cleaning.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
