Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a drug extraction centrifuge. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids with different densities in emulsions. Centrifuges are also required when extracting the active ingredients of drugs.

[0003] Existing centrifugal extraction devices for traditional Chinese medicine are not convenient to disassemble and clean during actual use. Excessive accumulation of medicinal residue can easily affect centrifugal extraction. Related technologies have achieved the effect of convenient disassembly and cleaning of the screen frame by setting up installation components, making it easy to remove the screen frame for cleaning and preventing excessive accumulation of medicinal residue from affecting the centrifugal extraction effect. This improves the convenience of the centrifugal extraction device for traditional Chinese medicine. However, during centrifugation, a large amount of active ingredients remain in these medicinal residues, requiring multiple centrifugations to achieve a high extraction efficiency, which has certain limitations and causes inconvenience in use.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] When using it, add the medicine to the inside of the centrifuge, start the motor inside the centrifuge to drive the centrifuge drum to rotate at high speed, and use the centrifugal force generated to separate the active ingredients in the medicine from the residue.

[0032] In related technologies, the installation of components allows for convenient disassembly and assembly of the mesh frame, facilitating its removal and cleaning. This prevents excessive accumulation of medicinal residue, which can negatively impact the centrifugal extraction process and improves the convenience of the centrifugal extraction device. However, during centrifugation, a significant amount of active ingredients remain in the residue, requiring multiple centrifugations to achieve higher extraction efficiency. This presents certain limitations and causes inconvenience in use.

[0033] To address some of the problems in related technologies, this application provides a drug extraction centrifuge. During use, simply align the locking block 22 on the mesh frame 21 with the slot at the top of the centrifuge cylinder 14 to complete the installation of the mesh frame 21, which is convenient and quick. Simultaneously, during drug centrifugation extraction, simply open the drive mechanism 26 to drive the turntable 25 and frame 23 downwards together. The turntable 25 compresses the drug residue downwards, thereby extracting most of the active ingredients and increasing the efficiency of drug extraction. After use, simply open the top cover of the centrifuge body 11 and pull it vertically upwards. The drive mechanism 26 will then drive the turntable 25 and frame 23 to slide out of the internal groove of the mesh frame 21, facilitating cleaning of the turntable 25 and increasing its service life.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-5This application provides a drug extraction centrifuge, including: a centrifuge body 11, with a support base 12 fixedly installed at its bottom; a control cabinet 13 fixedly connected to the top of the support base 12; a centrifuge cylinder 14 installed inside the centrifuge body 11 via a motor, and the motor at the bottom of the centrifuge cylinder 14 is electrically connected to the control cabinet 13; a compression assembly 2 is provided inside the centrifuge cylinder 14; the compression assembly 2 includes: a wire mesh frame 21, slidably connected to the inside of the centrifuge cylinder 14, and the wire mesh frame 21 is engaged with the centrifuge cylinder 14 via a locking block 22; a frame body 23 is provided inside the wire mesh frame 21; the frame body 23 is slidably connected to the inside of the wire mesh frame 21 via an externally fixed limiting block 24; a turntable 25 is rotatably connected inside the frame body 23; a drive mechanism 26 and a funnel 27 are provided on the top of the turntable 25, and a through groove located directly below the funnel 27 is opened inside the frame body 23.

[0036] In use, the drug to be extracted is first placed into the funnel 27. The drug slides down the funnel 27 through the groove inside the turntable 25 and falls into the mesh frame 21. Then, the motor at the bottom of the centrifuge body 11 is started, which drives the centrifuge cylinder 14 to rotate, thereby causing the mesh frame 21 and the frame 23 to rotate. Since the frame 23 is slidably connected to the turntable 25, and the turntable 25 is fixedly connected to the threaded sleeve 263, and the threaded sleeve 263 is not located on top of the turntable 25... The frame 23 is located at the center of the centrifuge drum, so the rotation of the frame 23 will not cause the turntable 25 to rotate. The centrifugal force generated when the frame 21 rotates at high speed will separate the active ingredients of the drug from the drug and allow them to pass through the filter mesh on the frame 21 and the centrifuge drum 14, flowing into the interior of the centrifuge body 11 and then out through the discharge port at the bottom of the centrifuge body 11. When installing the frame 21, align the locking block 22 on the frame 21 with the locking groove on the top of the centrifuge drum 14 and insert it. Then install the top cover with the drive mechanism 26 and the funnel 27. On the centrifuge body 11, slide the limiting block 24 into the groove inside the mesh frame 21, and then fix the top cover on the top of the centrifuge body 11 to complete the installation of the mesh frame 21. At this time, the top cover is rotatably connected to both the centrifuge cylinder 14 and the mesh frame 21, which facilitates limiting their movement when they rotate, making the process convenient and quick. Simultaneously, when centrifuging and extracting drugs, turn on the second motor 261 to drive the threaded rod 262 to rotate. Under the action of the external thread of the threaded rod 262, the... The moving threaded sleeve 263 drives the turntable 25 to move downward, so that the turntable 25 and the frame 23 slide downward along the inner groove of the mesh frame 21 through the limiting block 24, and compress the drug residue, thereby pressing out most of the active ingredients in the drug residue, thus increasing the efficiency of drug extraction. After use, the top cover of the centrifuge body 11 is opened and pulled vertically upward, so that the turntable 25 and the frame 23 can be driven out of the inner groove of the mesh frame 21 by the drive mechanism 26, which facilitates the cleaning of the turntable 25 and increases the service life of the turntable 25.

[0037] In some embodiments, the drive mechanism 26 includes: a second motor 261, which is fixedly installed on the top of the centrifuge body 11; a threaded rod 262 is fixedly connected to the output end of the bottom of the second motor 261; a threaded sleeve 263 is threadedly connected to the outside of the threaded rod 262, and the bottom of the threaded sleeve 263 is fixedly connected to the top of the turntable 25. The outside of the threaded rod 262 and the threaded sleeve 263 are coated with anti-rust paint to increase their service life.

[0038] In some embodiments, the second motor 261 and the funnel 27 are both fixedly installed on the top cover of the centrifuge body 11, and the top cover of the centrifuge body 11 is connected to the centrifuge body 11 by bolts, which makes it easy to disassemble the drive mechanism 26 and the turntable 25 as a whole by removing the top cover, thereby facilitating the cleaning of the turntable 25.

[0039] In some embodiments, a connecting component 3 is provided between the funnel 27 and the internal through groove of the frame 23; the connecting component 3 includes: a first cylinder 31, which is fixedly connected to the bottom of the funnel 27; a second cylinder 32 is slidably connected to the outside of the first cylinder 31; a sealing ring 33 is fixedly connected between the bottom of the second cylinder 32 and the internal through groove of the frame 23. When the turntable 25 is adjusted up and down by the drive mechanism 26, the second cylinder 32 will slide outside the first cylinder 31, thereby achieving the overall contraction of the bottom of the funnel 27, so that no matter where the turntable 25 moves inside the mesh frame 21, material can be added to the bottom of the turntable 25 through the funnel 27.

[0040] In some embodiments, the inner diameter of the second cylinder 32 is the same as the outer diameter of the first cylinder 31, and the inner diameter of the sealing ring 33 of the first cylinder 31 is the same as the aperture of the groove inside the turntable 25, which is used to convey materials and enhance the practicality of the device.

[0041] In some embodiments, a solenoid valve is fixedly installed inside the funnel 27 to facilitate the control of drug addition by switching the solenoid valve on and off.

[0042] In some embodiments, the locking block 22 is arranged around the outside of the wire frame 21, and the limiting block 24 is arranged around the outside of the frame 23. Multiple locking blocks 22 and limiting blocks 24 are provided to enhance the stability of the locking block 22 and the limiting block 24.

[0043] In some embodiments, when the centrifuge body 11 is performing centrifugation, the tops of the centrifuge cylinder 14 and the mesh frame 21 are rotatably connected to the bottom of the top cover of the centrifuge body 11. The rotation of the centrifuge cylinder 14 and the mesh frame 21 is limited by the top cover, thereby reducing the shaking that occurs when the centrifuge cylinder 14 and the mesh frame 21 rotate.
