Description

Technical Field

[0001] This utility model relates to the technical field of valine extraction equipment, specifically to a valine extraction device. Background Technology

[0002] Valine, scientifically known as 2-amino-3-methylbutyric acid, is a branched, nonpolar α-amino acid containing five carbon atoms. L-valine is one of the 20 amino acids that make up proteins and is an essential amino acid and glucogenic amino acid for mammals. D-valine is found in some actinomycins (such as valine). Symbol: Val or V. Valine is one of the eight essential amino acids for humans and can be synthesized from isobutyraldehyde. It is a white crystalline or crystalline powder, soluble in water and practically insoluble in ethanol.

[0003] In related technologies, valine is one of the eight essential amino acids for the human body and has high medicinal value. Therefore, some people have refined and processed it. Centrifugal separation equipment is required in the production and processing of valine. According to the search, CN215088027U discloses a centrifugal separation device for extracting valine, which includes an outer box and a centrifuge cylinder located inside the outer box. The top of the outer box is fixedly installed with an inlet, and the bottom of one side of the outer box is fixedly installed with a water outlet. The interior of the outer box is provided with a first driving component to drive the centrifuge cylinder to rotate. The periphery of the centrifuge cylinder is provided with an arc-shaped plate, which is connected to the inner cavity of the outer box through a buffer component. The effect is that by setting the arc-shaped plate, the arc-shaped plate is located on the periphery of the centrifuge cylinder.

[0004] However, after centrifugation, the solid precipitate of this valine separation and extraction device adheres directly to the bottom or inner wall of the centrifuge tube. If the precipitate is dense (e.g., high concentration of bacterial cells), it needs to be manually scraped or high-pressure washed, which makes the operation cumbersome and inconvenient to clean the centrifuge tube. In addition, a lot of fine particles (e.g., bacterial cell fragments, colloidal impurities, etc.) remain in the supernatant after centrifugation, which increases the difficulty of subsequent purification and also increases the complexity of the process. To solve the above problems, a valine extraction device is proposed to address these issues. Utility Model Content

[0005] In view of this, the present invention provides a valine extraction device. The present invention uses a motor to drive the support frame to rotate, thereby causing the separation cylinder placed on the support frame to rotate and centrifuge. After centrifugation, the supernatant is statically precipitated through a filter plate, which improves the quality of the supernatant. The separation cylinder is then removed by a handle. By manually turning the limit plate and fixing plate, the receiving ring is rotated, thereby separating the filter assembly from the separation cylinder. This allows the filter plate to be removed for cleaning or replacement, and also facilitates the cleaning of the sediment on the inner wall of the separation cylinder.

[0006] To solve the above-mentioned technical problems, this utility model provides a valine extraction device, including a casing at the bottom of a centrifuge cylinder, a motor inside the casing, a detachable cap at the top of the centrifuge cylinder, a placement rack rotatably mounted inside the centrifuge cylinder, the bottom of the placement rack being rotatably connected to the output shaft of the motor, multiple slots on the placement rack, a separation cylinder placed in each slot, a filter assembly detachably mounted in the middle of each separation cylinder, and a positioning assembly at the top of each separation cylinder.

[0007] The placement rack includes an upper support plate located at the upper part of the centrifuge tube, which is used to support and fix the upper half of the separation tube, and a lower support plate located at the lower part of the centrifuge tube, which is used to support the lower half of the separation tube. Multiple support columns are vertically arranged between the upper support plate and the lower support plate, which are used to connect the upper support plate and the lower support plate, so that the upper support plate and the lower support plate are connected as a whole to form the placement rack.

[0008] A bearing seat is fixedly installed in the center of the bottom of the lower support plate. The bearing seat is used to fix and install the connecting shaft, thereby connecting the motor and the placement frame. The connecting shaft is rotatably installed at the bottom of the bearing seat. The connecting shaft is used to connect the bearing seat to the coupling. Then, when the motor output shaft rotates, it drives the placement frame to rotate. The connecting shaft is rotatably connected to the motor output shaft through the coupling.

[0009] Several sliding plates are fixedly installed on the surfaces of the upper and lower support plates. The sliding plates are used to connect the slider to the upper support plate. The sliding plates are arc-shaped. Each sliding plate has a slider on both sides away from the center of the centrifuge. The slider is used to engage with the guide rail. The slider is arc-shaped. The upper and lower parts inside the centrifuge are each provided with a guide rail. The guide rail is used for the slider to rotate and move. The guide rail is used to stabilize the stability of the frame during rotation. The guide rail is circular in shape. The track inside the guide rail is adapted to the slider to slide.

[0010] Each separator has an internal thread located slightly below the center. This internal thread is used to receive an external thread. Each filter assembly includes an external thread that matches its corresponding internal thread. This external thread connects with the internal thread, thereby connecting the receiving ring to the inner wall of the separator. A receiving ring is fixedly installed at the top of the external thread. The receiving ring is used to place the filter plate. The filter plate is placed inside the receiving ring. The filter plate is used to improve the liquid-liquid separation effect of the supernatant after solid-liquid separation in the separator. The filter plate is circular.

[0011] A fixing plate is symmetrically arranged on the upper part of the receiving ring. The fixing plate is used to install the limiting plate. The fixing plate is set vertically. On the side of the fixing plate facing the center of the filter plate, there is a horizontal limiting plate. The limiting plate is used to open threaded holes and fix the limiting bolts. Each limiting plate has a threaded hole in the middle, and a limiting bolt is installed in each threaded hole. The limiting bolt is used to drive the pressing plate to move up and down. A pressing plate is set at the bottom of each limiting bolt. The pressing plate is used to press the filter plate to prevent the filter plate from being thrown away during rotation. The pressing plate is in contact with the surface of the filter plate. The limiting plate is also used to limit the pressing plate, thereby controlling the gap at the top of the filter plate for easy disassembly and replacement.

[0012] Each positioning component includes a positioning ring fixed to the outer wall of the top of the corresponding separation cylinder. The positioning ring is used to install pins and handles. Each positioning ring has multiple pins at its bottom, which are inserted into slots to position the upper part of the separation cylinder and prevent excessive shaking when the separation cylinder rotates. Each pin has a slot at its bottom to receive the pin, thereby connecting the positioning ring to the upper support plate. The slots are all embedded in the top of the upper support plate.

[0013] Each positioning component also includes a handle symmetrically arranged on the top of the positioning ring. The handle is used to facilitate the operator to remove the separation cylinder after solid-liquid separation. The handle is a hollow rectangle, and the bottom of the handle is rotatably set on the top of the positioning ring via a pivot. The rotatable design is used to reduce the space occupied by the handle.

[0014] The bottom of the cylinder cover is equipped with multiple plugs, which are used to seal the top of the separation cylinder to prevent the supernatant from being thrown away during centrifugation. The number of plugs is matched with the number of separation cylinders. The plugs are circular and are matched to the top opening of the separation cylinder for sealing.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The motor drives the support frame to rotate, which in turn causes the separation cylinder placed on the support frame to rotate and centrifuge. After centrifugation, the supernatant is allowed to settle through the filter plate, which improves the quality of the supernatant. The separation cylinder is then removed by the handle. The receiving ring is rotated by manually turning the limit plate and fixing plate, which separates the filter assembly from the separation cylinder. This allows the filter plate to be removed for cleaning or replacement, and also facilitates the cleaning of the sediment on the inner wall of the separation cylinder.

[0016] 2. The internal thread is used to receive the external thread, and the external thread is used to connect with the internal thread, so that the receiving ring is connected to the inner wall of the separation cylinder. The inner ring of the receiving ring is used to place the filter plate. The filter plate is placed inside the receiving ring, which facilitates the detachable connection between the separation cylinder and the filter assembly. The filter plate is used to make the supernatant after solid-liquid separation in the separation cylinder more liquid.

[0017] 3. The handle is used to facilitate the operator to take out the separation cylinder after solid-liquid separation. The flip-up design reduces the space occupied by the handle. The plug is used to seal the top of the separation cylinder to prevent the supernatant from being thrown away when the separation cylinder is rotated and centrifuged. Attached Figure Description
