[0002] Plant extracts are products made from plants as raw materials. According to the needs of the final use of the extracted product, they undergo a physical and chemical extraction and separation process to selectively obtain and concentrate one or more active ingredients in the plant without changing the structure of the active ingredients. The plant extraction process requires the use of an extraction tank, which uses the solubility difference between the solvent and different components in the raw material to achieve the extraction and separation of the target ingredients.

[0003] When the existing extraction tank is in use, the raw materials are prone to floating during the extraction process and float on the surface of the extraction solvent, resulting in uneven contact; the equipment heating efficiency is slow, affecting the extraction efficiency and product quality; and the discharge is not smooth, and the residue is difficult to clean up. Therefore, an extraction device for plant raw materials is needed to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an extraction device for plant raw materials, comprising an extraction tank body and a heating mechanism, wherein a material pressing mechanism and a heat conducting plate are arranged in the extraction tank body;

[0006] A feeding pipe is arranged on the side of the extraction tank, a discharge port is arranged on the bottom of the extraction tank, a manhole is arranged on the top of the extraction tank, the pressing mechanism is installed on the inner end surface of the extraction tank and is slidably connected thereto, the pressing mechanism comprises a buoyancy ring, a filter plate and a waste filter box, the buoyancy ring is fixedly installed on the upper end surface of the filter plate, and the waste filter box is detachably installed at the center of the upper end surface of the filter plate.

[0008] As a preferred extraction device for plant materials of the utility model, a limiting ring is provided on the inner end surface of the extraction tank body, and the limiting ring is located at the upper end of the connection between the feeding pipe and the extraction tank body.

[0009] As a preferred device for extracting plant materials of the utility model, the filter plate is a conical structure, and the center height of the filter plate is lower than the edge height thereof.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model cooperates with the buoyancy ring and the filter plate, and automatically adjusts the position by the buoyancy principle, ensuring that the plant raw materials are always effectively pressed into the extraction liquid. This floating structure not only avoids the reduction of the contact area of ​​the raw materials due to compression and accumulation, but also can continue to apply pressure as the liquid level drops, ensuring the dynamic and full contact between the plant raw materials and the extraction liquid, greatly improving the extraction efficiency. The conical filter plate design ensures that even if a small amount of raw materials penetrates the filter plate, it will slide along the cone surface to the central waste filter box due to its own weight, which is convenient for later cleaning and improves the convenience of equipment cleaning.

[0015] 2. The utility model uses a spiral heating wire as a heating mechanism and arranges a spiral heat-conducting strip on its inner end surface. This design not only increases the heating area, but also enhances the heat energy transfer efficiency through the spiral structure of the heat-conducting strip, making the heat distribution more uniform and greatly improving the heating efficiency. The heat-conducting strip with a semicircular cross-section also reduces material residue and facilitates cleaning and maintenance, which helps to maintain the efficient operation of the equipment in the long run.

[0016] 3. The utility model uses a spiral heat-conducting strip design to promote vortex flow of the raw materials inside the equipment during the discharge process. This dynamic fluid movement helps to quickly and thoroughly discharge the internal raw materials, reduce residues, speed up the discharge speed, and improve the overall operating efficiency.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 , an extraction device for plant raw materials, comprising an extraction tank 1 body and a heating mechanism 2, wherein a material pressing mechanism 3 and a heat conducting plate 4 are arranged in the extraction tank 1 body;

[0024] A feeding pipe 101 is provided on the side of the extraction tank 1, a discharge port 102 is provided at the bottom of the extraction tank 1, a manhole 103 is provided on the top of the extraction tank 1, and a pressing mechanism 3 is installed on the inner end surface of the extraction tank 1 and is slidably connected thereto. The pressing mechanism 3 includes a buoyancy ring 301, a filter plate 302 and a waste filter box 303. The buoyancy ring 301 is fixedly installed on the upper end surface of the filter plate 302, and the waste filter box 303 is detachably installed at the center of the upper end surface of the filter plate 302.

[0025] Furthermore, the buoyancy ring 301 is a circular hollow stainless steel tube, the filter plate 302 is a honeycomb stainless steel plate, the outer diameters of the buoyancy ring 301 and the filter plate 302 are equal to the inner diameter of the extraction tank 1 , and the buoyancy ring 301 is slidably connected to the extraction tank 1 .

[0026] The buoyancy ring 301 floats on the upper end surface of the extract under the action of buoyancy, and the filter plate 302 fully presses the raw material into the extract, so that the plant raw material is fully in contact with the extract, increasing the contact area between the extract and the plant raw material, thereby improving the extraction efficiency. The floating structure can provide sufficient space for the plant raw material to avoid compressed accumulation of the plant raw material. At the same time, it can float with the liquid level of the extract as the extract decreases, and continuously press the plant raw material in the extract.

[0027] Furthermore, a limiting ring 104 is provided on the inner end surface of the main body of the extraction tank 1 , and the limiting ring 104 is located at the upper end of the connection between the feeding pipe 101 and the main body of the extraction tank 1 .

[0028] The initial position of the pressing mechanism 3 is limited by the limiting ring 104 to ensure that the plant raw material is located at the lower end of the pressing mechanism 3 when feeding, so as to prevent the raw material from floating up.

[0029] Furthermore, the filter plate 302 is a conical structure, and the center height of the filter plate 302 is lower than the edge height thereof.

[0030] When a small amount of raw materials passing through the filter plate 302 cannot flow back to the lower end of the filter plate 302, they can slide along the upper end surface of the filter plate 302 to the waste filter box 303 at the center of the filter plate 302 during flushing, which is convenient for centralized cleaning later.

[0031] Furthermore, a screw hole 305 is provided at the center of the filter plate 302 , and an outer end surface of the waste filter box 303 is provided with an external thread corresponding to the screw hole 305 . The waste filter box 303 is inserted into the screw hole 305 and is threadedly connected to the filter plate 302 .

[0032] The threaded waste filter box 303 structure makes it easy for operators to remove it from the manhole 103 for flushing, thereby improving the convenience of equipment cleaning.

[0033] Furthermore, a vertical plate 304 is provided on the top of the inner end surface of the waste filter box 303 .

[0034] The vertical plate 304 facilitates workers to enter the extraction tank 1 to turn the knob of the waste filter box 303, and the vertical plate 304 can be directly hooked from the manhole 103 by a long hook to turn the knob, thereby facilitating the removal of the waste filter box 303.

[0035] Furthermore, the heating mechanism 2 is a spiral heating wire, the heat conducting plate 4 is located at the inner end surface of the heating mechanism 2, and the inner end surface of the heating mechanism 2 is provided with a heat conducting strip 401, which is a spiral structure and has a semicircular cross-section.

[0036] The heat exchange area between the heating mechanism 2 and the extractant is increased by the heat conducting plate 4 with the heat conducting strips 401, thereby improving the heating efficiency. The spiral structure enables a vortex to be formed inside the device when the device is discharging materials, thereby improving the discharging efficiency. The semicircular structure is not easy to leave waste.

[0037] When using the device, first ensure that all parts are intact, especially whether the buoyancy ring 301, filter plate 302, waste filter box 303, heat conduction plate 4 and heating mechanism 2 are installed correctly. Before use, thoroughly clean and disinfect the extraction tank 1 to ensure that there is no residue that affects the extraction quality. Slowly add the pre-treated plant raw material into the extraction tank 1 through the feeding pipe 101, and pay attention to controlling the feeding speed to avoid raw material accumulation or blockage. Press the plant raw material through the pressing mechanism 3 to prevent the raw material from floating up. Turn on the power, start the spiral heating wire, and quickly heat the extract through the heat conduction plate 4 and the heat conduction strip 401. As the heating, the extraction solvent evaporates, and the buoyancy ring 301 will drop with the extraction solvent liquid level, driving the filter plate 302 to press the raw material into the extraction liquid, forming a good material contact, automatically adapting to the change of the liquid level, and continuously performing efficient extraction. After the extraction is completed, clean the extraction tank 1 through the manhole 103. If necessary, enter the extraction tank 1 to remove the waste filter box 303 for washing.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
