Description

Technical Field

[0001] This utility model relates to the field of medicinal liquid extraction technology, and more specifically, to a separation device for extracting plant medicines. Background Technology

[0002] Separation devices for herbal medicine extraction are a type of equipment used to extract active ingredients from plant materials and separate them from impurities. They utilize porous media to separate liquids and solid particles. When a mixture containing herbal medicine extracts passes through a filter medium, solid impurities are trapped on the surface of the medium, while the liquid portion passes through, thus achieving separation.

[0003] Centrifugal separators are used to separate plant residues and extracts, effectively achieving separation through centrifugation combined with a filtration system. However, existing centrifugal separators' filtration mechanisms tend to retain large amounts of plant residues, requiring frequent disassembly and cleaning to prevent clogging and ensure proper separation quality. Therefore, we propose a separation device for plant extracts. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a separation device for extracting plant medicines, so as to solve the technical problem that current centrifugal separation devices need to be frequently disassembled and cleaned to avoid blockage and affect the separation quality.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a separation device for extracting plant medicines, including a shell, a base, a centrifugal mechanism and a conical cover. The outer side of the base is provided with a side groove, and a liquid collection box is inserted and installed in the side groove. A turntable is rotatably installed at the middle of the upper end face of the base via a rotating shaft. The shell is installed on the upper end face of the base, and the turntable is located at the bottom of the shell. A top cover is rotatably installed at the opening of the upper end face of the shell via a hinge. A guide rail is provided on the inner side of the top cover. The centrifugal mechanism is installed inside the shell, and the centrifugal mesh of the centrifugal mechanism fits the inclined surface inside the shell.

[0006] In use, this invention is powered by an external power source. The operator starts the device via an external control device, feeding the crushed plant mixture into the feed hopper, then closing the top cover. The built-in motor in the base starts the turntable, which rotates intermittently. The turntable, through the connecting plate, drives the centrifugal mesh of the centrifugal mechanism to rotate. The centrifugal mesh drives the feed hopper to rotate, generating centrifugal force that forces the liquid medicine in the mixture through the feed hopper into the centrifugal mesh. Large particles of residue remain in the feed hopper. The centrifugal force generated by the rotation of the centrifugal mesh further filters the liquid medicine after the initial filtration, allowing the liquid medicine to be guided into the collection box through the liquid guide tube. Small particles of impurities remain in the centrifugal mesh. Due to centrifugal action, the small particles of residue adhere to the inclined inner surface of the centrifugal mesh. The intermittent rotation causes the residue adhering to the inner wall of the centrifugal mesh to fall off due to gravity. The secondary filtration method, extending to the bottom of the centrifuge mesh, effectively reduces the frequency of disassembly and cleaning. The vertical centrifuge design, combined with the conical centrifuge mesh structure, guides small particles of residue to the bottom of the mesh during intermittent centrifugal separation and filtration, facilitating later disassembly and cleaning. Inner spiral strips cover the residue at the bottom of the mesh, preventing it from rebounding and impacting the inclined inner surface of the mesh during subsequent centrifugal rotations. As the number of filtration cycles increases, the amount of residue grows, and frequent backflow can clog the mesh filter holes, affecting filtration quality. The conical centrifuge mesh design, along with the anti-backflow inner spiral strips, isolates the small particles of residue remaining at the bottom, preventing clogging due to untimely cleaning and ensuring processing quality.

[0007] Preferably, a liquid guide tube is installed in a ring array on the outer side of the upper end face of the base, and the lower end of the liquid guide tube passes through the connecting side groove, while the upper end of the liquid guide tube passes through the interior of the docking shell.

[0008] Preferably, the centrifugation mechanism consists of a top ring, a centrifugation mesh cover, a docking plate, and a cone cover. The docking plate is installed at the lower end of the centrifugation mesh cover and is connected to the turntable. The top ring is installed on the upper opening of the centrifugation mesh cover.

[0009] Preferably, the centrifuge mesh cover is cone-shaped, and an inner spiral strip is fixed on the inner side of the centrifuge mesh cover. The inner spiral strip is spiral-shaped, and the inner spiral strip has staggered partitions.

[0010] Preferably, the top ring has a ring array of sliders fixed on its upper side, and the sliders slide and engage with the guide rail, and the top ring has a slot on its upper side.

[0011] Preferably, the outer side of the cone cover is provided with a ring array of locking blocks, the cone cover is inserted into the upper opening of the centrifuge mesh cover, and the locking blocks are aligned with the corresponding locking slots.

[0012] Preferably, a material mesh cylinder is inserted into the middle opening of the cone cover of the centrifugal mechanism, and the lower end of the material mesh cylinder is located inside the centrifugal mesh cover.

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

[0014] 1. This utility model, through the design of a centrifugal mechanism, ensures that during centrifugal filtration, large particles of medicinal residue remain inside the material screen cylinder. After the medicinal liquid enters the centrifugal screen, it undergoes secondary filtration through rotation, allowing the medicinal liquid to be guided into the liquid collection box through the liquid guide cylinder. Small particles of impurities remain inside the centrifugal screen. Due to centrifugal action, the small particles of medicinal residue adhere to the inclined inner surface of the centrifugal screen. Intermittent rotation causes the medicinal residue adhering to the inner wall of the centrifugal screen to fall to the bottom of the centrifugal screen due to gravity. This secondary filtration method effectively reduces the frequency of disassembly and cleaning. At the same time, the vertical centrifugal design, combined with the conical centrifugal screen structure, guides the small particles of medicinal residue to remain at the bottom of the centrifugal screen during the intermittent centrifugal separation and filtration process, facilitating subsequent disassembly and cleaning.

[0015] 2. This utility model also incorporates an inner spiral strip design to cover the residue at the bottom of the centrifuge mesh, preventing it from rebounding and impacting the inclined surface inside the mesh during subsequent centrifugal rotations. As the number of filtration cycles increases, the amount of residue grows, and frequent rebounds can easily clog the filter holes of the centrifuge mesh, affecting filtration quality. Furthermore, the conical centrifuge mesh design, combined with the anti-rebound inner spiral strip, isolates small particles of residue remaining at the bottom, preventing clogs caused by untimely cleaning and ensuring processing quality.

Detailed Implementation

[0024] like Figures 1 to 5 As shown, this utility model relates to a separation device for extracting plant medicines, including a shell 2, a base 3, a centrifugal mechanism 4, and a conical cover 407. A side groove 303 is provided on the outer side of the base 3, and a liquid collection box 301 is inserted into the side groove 303. A turntable 304 is rotatably mounted on the middle of the upper end face of the base 3 via a rotating shaft. The shell 2 is mounted on the upper end face of the base 3, and the turntable 304 is located at the bottom of the shell 2. A liquid guide tube 302 is arranged in a circular array on the outer side of the upper end face of the base 3, with the lower end of the liquid guide tube 302 penetrating into the side groove 303 and the upper end of the liquid guide tube 302 penetrating into the shell 2. A top cover 1 is rotatably mounted on the opening of the upper end face of the shell 2 via a hinge. A guide rail 101 is provided on the inner side of the top cover 1. The centrifugal mechanism 4 is installed inside the shell 2 and consists of a top ring 401, a centrifugal mesh cover 403, a docking plate 404, and a conical cover 407. The docking plate 404 is mounted on... Installed at the lower end of the centrifuge screen 403 and connected to the connecting plate 404 and the turntable 304, the top ring 401 is installed on the upper opening of the centrifuge screen 403. During centrifugal filtration, large particles of medicine residue remain in the material screen cylinder 5. After the medicine enters the centrifuge screen 403, it undergoes secondary filtration through rotation, allowing the medicine to be guided into the liquid collection box 301 through the liquid guide cylinder 302. Small particles of impurities remain in the centrifuge screen 403. Due to centrifugation, the small particles of medicine residue adhere to the inclined inner surface of the centrifuge screen 403. Intermittent rotation causes the medicine residue adhering to the inner wall of the centrifuge screen 403 to fall to the bottom of the centrifuge screen 403 due to gravity. The secondary filtration method can effectively reduce the frequency of disassembly and cleaning. At the same time, the vertical centrifuge design, combined with the conical centrifuge screen 403 structure, can guide the small particles of medicine residue to remain at the bottom of the centrifuge screen 403 during the intermittent centrifugal separation and filtration process, making it easy to disassemble and clean later.

[0025] like Figures 2 to 7As shown, this utility model relates to a separation device for extracting plant medicines, including a shell 2, a base 3, a centrifugal mechanism 4, and a conical cover 407. The centrifugal mesh 403 of the centrifugal mechanism 4 is fitted to the inner inclined surface of the shell 2. The centrifugal mesh 403 is conical in design, and an inner spiral bar 405 is fixed on the inner side of the centrifugal mesh 403. The inner spiral bar 405 is spirally designed, and the inner spiral bar 405 has staggered distribution of partitions 406. A slider 402 is fixed in an annular array on the upper side of the top ring 401, and the slider 402 slides and engages with the guide rail 101. A slot is opened on the upper side of the top ring 401. A locking block is distributed in an annular array on the outer side of the conical cover 407. The conical cover 407 is inserted into the upper opening of the centrifugal mesh 403, and the locking blocks engage. The corresponding slot is where the material screen cylinder 5 is inserted into the middle opening of the cone cover 407 of the centrifugal mechanism 4, with the lower end of the material screen cylinder 5 located inside the centrifugal screen cover 403. The inner spiral strip 405 covers the drug residue at the bottom of the centrifugal screen cover 403, preventing the drug residue at the bottom from rebounding and impacting the inclined surface inside the centrifugal screen cover 403 due to centrifugal force when centrifuging again. As the number of filtrations increases, the amount of drug residue increases, and frequent rebound can easily clog the filter holes of the centrifugal screen cover 403, affecting the filtration quality. At the same time, the cone-shaped centrifugal screen cover 403 design, together with the inner spiral strip 405 to prevent rebound, isolates the small particles of drug residue remaining at the bottom, avoiding clogging of the centrifugal screen cover 403 due to untimely cleaning, and ensuring processing quality.

[0026] Working Principle: This embodiment provides a separation device for extracting medicinal plants. During use, it is powered by an external power source. The operator starts the device via an external control device, feeding the crushed plant mixture into the feed screen cylinder 5. Then, the top cover 1 is closed, and the built-in motor in the base 3 drives the turntable 304 to rotate intermittently. The turntable 304, through the connecting plate 404, drives the centrifugal screen 403 of the centrifugal mechanism 4 to rotate. The centrifugal screen 403 drives the feed screen cylinder 5 to rotate, generating centrifugal force that causes the medicinal liquid in the mixture to pass through the feed screen cylinder 5 and enter the centrifugal screen 403. Large particles of medicinal residue remain in the feed screen cylinder 5. The centrifugal screen 403, through rotation, generates centrifugal force to perform a secondary filtration of the initially filtered medicinal liquid, allowing it to flow through the liquid guide cylinder 302 into the liquid collection box 301. Small particles of impurities remain in the centrifugal screen 403. Due to centrifugal action, the small particles of medicinal residue adhere to each other. The inclined inner surface of the centrifugal mesh 403, through intermittent rotation, causes the drug residue adhering to the inner wall of the centrifugal mesh 403 to fall to the bottom of the centrifugal mesh 403 due to gravity. This secondary filtration method effectively reduces the frequency of disassembly and cleaning. At the same time, the vertical centrifugal design, combined with the conical centrifugal mesh 403 structure, uses inner spiral strips 405 to cover the drug residue at the bottom of the centrifugal mesh 403, preventing the drug residue at the bottom from rebounding and impacting the inclined inner surface of the centrifugal mesh 403 due to centrifugal force during subsequent centrifugal rotations. As the number of filtrations increases, the amount of drug residue increases, and frequent rebound can easily clog the filter holes of the centrifugal mesh 403, affecting the filtration quality. In addition, the conical centrifugal mesh 403 design, combined with the anti-rebound inner spiral strips 405, isolates small particles of drug residue remaining at the bottom, preventing clogging of the centrifugal mesh 403 due to untimely cleaning and ensuring processing quality.
