Description

Technical Field

[0001] This utility model relates to the technical field of bitter substance extraction equipment, and in particular to a bitter substance extraction tank with pretreatment function. Background Technology

[0002] Bitter compounds are a class of naturally occurring active ingredients widely found in plants. They possess antibacterial, anti-inflammatory, and metabolic-regulating biological activities and are widely used in medicine, health foods, and feed additives. Common examples include chicory root extract, berberine, artemisinin, and momordicin, all of which fall into the category of bitter compounds.

[0003] Currently, the extraction process of bitter substances usually includes steps such as "raw material crushing - solvent extraction - solid-liquid separation", which are mostly operated independently: first, the plant raw materials (such as bitter melon, chicory root, etc.) are crushed to a certain particle size using separate crushing equipment (such as crusher, pulverizer), then the crushed material is transferred to the extraction tank for solvent soaking and extraction, and finally filtered using filtration equipment.

[0004] In practice, the extraction of bitter substances is inefficient because the raw material crushing, solvent extraction, and solid-liquid separation are performed separately. Utility Model Content

[0005] Therefore, in response to the above problems, this utility model proposes a bitter substance extraction tank with pretreatment function, which solves the technical problem of low work efficiency in the extraction of bitter substance caused by the separate operation of raw material crushing, solvent extraction and solid-liquid separation in traditional processes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bitter substance extraction tank with pretreatment function includes an extraction tank body, a cover on the extraction tank body, a crushing device installed on the cover, a feed pipe on the upper part of the side wall of the extraction tank body, a water outlet pipe on the lower part of the side wall of the extraction tank body, a stirring assembly installed at the bottom of the extraction tank body, an electric slag discharge gate valve installed on the upper part of the side wall of the extraction tank body, and a slag filter device installed inside the extraction tank body.

[0008] The filter device includes a No. 1 drive motor fixed on the cover, the output shaft of the No. 1 drive motor is connected to a movable rod, the lower end of the movable rod is equipped with an installation sleeve, the side wall of the installation sleeve is respectively equipped with a scraper and a connecting rod, and the surface of the connecting rod is rotatably fitted with a slag pressing roller.

[0009] The extraction tank is detachably equipped with a filter screen frame, which contains a filter screen. The surface of the filter screen is in contact with the scraper plate and the pressing roller, respectively. The side wall of the filter screen frame is provided with a discharge port corresponding to the electric discharge gate valve.

[0010] Furthermore, multiple fastening frames are installed on the upper edge of the filter screen frame, and fastening hooks that engage with each fastening frame are provided on the inner side wall of the extraction tank. The filter screen frame is securely hung on the inner side wall of the extraction tank through each fastening frame.

[0011] Furthermore, the crushing device includes a crushing chamber mounted on the cover, a feeding pipe extending into the extraction tank and connected to the bottom of the crushing chamber, crushing blades mounted inside the crushing chamber, and a second drive motor mounted outside the crushing chamber for driving the crushing blades to crush materials.

[0012] Furthermore, the stirring assembly consists of a stirring paddle located inside the extraction tank and below the filter screen, and a third drive motor that drives the stirring paddle to rotate.

[0013] Furthermore, a transparent observation window is provided on the side wall of the extraction tank, and the transparent observation window is located below the filter frame.

[0014] Furthermore, a flow control valve is installed on the feed pipe.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] This invention primarily optimizes the operation of traditional single-use equipment by integrating raw material crushing, solvent extraction, and solid-liquid separation, thereby improving the extraction efficiency of cucurbitacin and saving significant operating time. Specifically, the device utilizes a crushing unit to crush the material to be extracted for cucurbitacin extraction. The processed material then falls directly into the extraction tank. A filter screen at the upper part of the extraction tank catches the material, and then an appropriate amount of cucurbitacin extraction solvent is introduced through the feed pipe. The material is soaked in the solvent until it covers the filter screen, leaching out the cucurbitacin. Simultaneously, a stirring component at the lower part of the tank agitates the solvent, accelerating cucurbitacin diffusion and improving soaking efficiency. Once the cucurbitacin in the material has been fully extracted, the cucurbitacin extraction solvent containing cucurbitacin is discharged through the outlet pipe. The liquid level is observed to drop below the filter screen through a transparent observation window. Then, the first drive motor of the filter residue device is activated. Under the action of the scraper and pressing roller, the residue on the filter screen is pressed, squeezing out the remaining cucurbitacin extraction solvent. Since the scraper and pressing roller operate synchronously, the material can be scraped up and rolled again simultaneously, repeating this process to further optimize the pressing effect and achieve solid-liquid separation. Finally, the electric slag discharge valve is opened, and the residue is pushed out by the scraper for easy collection. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to Figures 1-4 This embodiment provides a bitter substance extraction tank with pretreatment function. Its structure includes an extraction tank body 1 for bitter substance extraction, a cover body 2 on the extraction tank body 1, a crushing device 3 installed on the cover body 2, a feed pipe 5 for the bitter substance extraction solvent (the bitter substance extraction solvent is a solvent used for bitter substance leaching, such as ethanol, methanol, etc.) to be input into the extraction tank body 1 through the side wall, a water outlet pipe 6 for the bitter substance extraction solvent to be discharged through the lower part of the side wall of the extraction tank body 1, a stirring assembly 7 installed at the bottom of the extraction tank body 1, an electric slag discharge gate valve 8 installed on the upper part of the side wall of the extraction tank body 1, and a slag filter device installed inside the extraction tank body 1.

[0024] Specifically:

[0025] The pulverizing device 3 includes a pulverizing chamber 32 mounted on the cover 2, a feeding pipe 31 extending into the extraction tank 1 and connected to the bottom of the pulverizing chamber 32, pulverizing blades (not shown in the figure, these are existing devices in the art and will not be described in detail here) mounted inside the pulverizing chamber 32, and a secondary drive motor 33 mounted outside the pulverizing chamber 32 for driving the pulverizing blades to pulverize the material. In use, the material for bitter substance extraction is placed into the pulverizing chamber 32, and the secondary drive motor 33 is started to drive the pulverizing blades to pulverize the material, which then falls into the extraction tank 1 through the feeding pipe 31.

[0026] The filter device includes a first drive motor 11 fixed on the cover 2. The output shaft of the first drive motor 11 is connected to a movable rod 12. An installation sleeve 13 is installed at the lower end of the movable rod 12. A scraper 14 and a connecting rod 15 are respectively installed on the side wall of the installation sleeve 13. A pressing roller 16 is rotatably fitted on the surface of the connecting rod 15.

[0027] The extraction tank 1 is detachably equipped with a filter screen frame 17, and a filter screen is provided inside the filter screen frame 17 (not marked in the figure, but those skilled in the art should understand the installation position and method of the filter screen). The surface of the filter screen is in contact with the slag scraper 14 and the slag pressing roller 16 respectively. The side wall of the filter screen frame 17 is provided with a slag discharge port 18 corresponding to the electric slag discharge gate valve 8.

[0028] The extraction tank 1 is also provided with a transparent observation window 4 on its side wall. The transparent observation window 4 is located below the filter frame 17 and is used to observe the liquid level inside the extraction tank 1.

[0029] The filter screen receives the material falling from the feed pipe 31. An appropriate amount of cucurbitacin extraction solvent is introduced through the feed pipe 5, submerging the filter screen to soak the material and leach out the cucurbitacin. Once the cucurbitacin in the material has been sufficiently leached out, the cucurbitacin extraction solvent containing cucurbitacin is discharged through the outlet pipe 6. The liquid level is observed to drop below the filter screen through the transparent observation window 4. Then, the first drive motor 11 of the filter residue device is activated. Under the action of the scraper 14 and the pressing roller 16, the residue on the filter screen is pressed, squeezing out the remaining cucurbitacin extraction solvent containing cucurbitacin. Since the scraper 14 and the pressing roller 16 operate synchronously, the scraper 14 can simultaneously scrape up the pressed material and roll it again, repeating this process to further optimize the pressing effect and achieve solid-liquid separation. Finally, open the electric slag discharge gate valve 8, and use the scraper plate 14 to push the residue out of the electric slag discharge gate valve 8 for easy collection of the residue.

[0030] Furthermore, multiple fastening frames 19 are installed on the upper edge of the filter frame 17, and fastening hooks 20 are provided on the inner wall of the extraction tank 1 to fasten with each fastening frame 19. The filter frame 17 is securely hung on the inner wall of the extraction tank 1 through each fastening frame 19. This facilitates the disassembly, cleaning, and installation of the filter frame 17.

[0031] Furthermore, the stirring assembly 7 includes a stirring paddle 72 located inside the extraction tank 1 and below the filter screen frame 17, and a third drive motor 71 that drives the stirring paddle 72 to rotate. During the leaching of cucurbitacin from the material by the cucurbitacin extraction solvent, the third drive motor 71 is activated to drive the stirring paddle 72 to stir, thereby accelerating the diffusion of cucurbitacin and improving the leaching efficiency.

[0032] Furthermore, a flow control valve (not shown in the figure) can be installed on the feed pipe 5 to control the dosage of the bitter extract solvent input into the extraction tank 1.

[0033] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
