Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal extractors, in particular to a centrifugal extractor for extracting and separating amino acid mixed solution. Background Technique

[0002] A centrifugal extractor for extracting and separating amino acid mixed solution is a device specifically designed for the transfer or separation of substances between liquid phases. It uses centrifugal force to accelerate the liquid-liquid separation process and realizes the efficient extraction and separation of amino acid mixed solution through two main steps: mixing mass transfer and centrifugal separation.

[0003] In the prior art, in order to ensure the separation efficiency of the centrifugal extractor, it is usually necessary to stir and mix the amino acid mixed solution before inputting it into the centrifugal extractor. However, the stirring shaft of the existing stirring and mixing device usually runs continuously for a long time. Long-term use will not only cause increased wear, shorten the service life of the equipment, and increase the maintenance cost, but also when stirring is not required, it often needs to be manually turned off by the staff, which not only increases the burden on the staff, but also causes the stirring shaft to continue running when it is not needed, thus wasting energy and accelerating the wear and failure rate of the stirring shaft.

[0004] Therefore, we have proposed a centrifugal extractor for extracting and separating amino acid mixed solution to solve the above problems. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present invention provides a centrifugal extractor for extracting and separating amino acid mixed solution, which solves the problems put forward in the above background technique.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A centrifugal extractor for extracting and separating amino acid mixed solution includes a centrifuge. A liquid inlet pipe is fixedly connected to the centrifuge. A stop valve is fixedly connected through the center of the liquid inlet pipe. A stop rod is slidably connected through the upper end of the stop valve. One end of the liquid inlet pipe away from the centrifuge is fixedly connected with a liquid storage tank. A stirring shaft is rotatably connected through the liquid storage tank. A frame is fixedly connected to the outer surface of the liquid storage tank near the centrifuge. A power switch is fixedly connected to the side wall of the frame. The power switch is electrically connected to the stirring shaft. A lifting plate is slidably connected inside the frame. A lever is fixedly connected to the side of the lifting plate close to the power switch. A circular ring is fixedly connected to the end of the lifting plate away from the frame. The circular ring is sleeved on the stop rod.

[0008] As a further scheme of the utility model: A fixing plate is fixedly connected to the upper end of the stop rod. A limiting plate is fixedly connected to the outer surface of the stop rod. The limiting plate is located below the circular ring.

[0010] As a further solution of the utility model: a shaft sleeve is sleeved on the outer surface of the stirring shaft, the shaft sleeve penetrates through the liquid storage tank, vertical grooves are symmetrically formed on the outer surface of the stirring shaft, the shaft sleeve is vertically slidably connected to the outer surface of the stirring shaft through the vertical grooves, and a plurality of stirring rods are fixedly connected to the outer surface of the shaft sleeve.

[0011] As a further solution of the utility model: sliding rods are symmetrically and fixedly connected to the upper end of the outer surface of the shaft sleeve, a hollow column is sleeved outside the shaft sleeve, the hollow column is fixedly connected to the upper end surface of the liquid storage tank, a reciprocating lifting groove is formed on the inner wall of the hollow column, and the far ends of the sliding rods away from the shaft sleeve are slidably connected in the reciprocating lifting groove.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1.

At the same time, this design adopts automatic control, effectively reducing the steps of manual operation, avoiding the cumbersome process of manually starting and stopping stirring, thereby saving manpower and time.

[0014] 2.

Specific embodiments

[0021] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] As Figures 1-4 shown, a centrifugal extractor for extracting and separating an amino acid mixture solution includes a centrifuge 1. A liquid inlet pipe 3 is fixedly connected to the centrifuge 1. A stop valve 4 is fixedly connected through the center of the liquid inlet pipe 3. A stop rod 11 is slidably connected through the upper end of the stop valve 4. One end of the liquid inlet pipe 3 away from the centrifuge 1 is fixedly connected to a liquid storage tank 2. A stirring shaft 6 is rotatably connected through the liquid storage tank 2. A frame 8 is fixedly connected to one side of the outer surface of the liquid storage tank 2 close to the centrifuge 1. A power switch 16 is fixedly connected to the side wall of the frame 8. The power switch 16 is electrically connected to the stirring shaft 6. A lifting plate 10 is slidably connected inside the frame 8. A lever 15 is fixedly connected to one side of the lifting plate 10 close to the power switch 16. One end of the lifting plate 10 away from the frame 8 is fixedly connected to a ring 14. The ring 14 is sleeved on the stop rod 11.

[0024] In this embodiment, as Figure 2 shown, a fixing plate 12 is fixedly connected to the upper end of the stop rod 11, and a limiting plate 13 is fixedly connected to the outer surface of the stop rod 11. The limiting plate 13 is located below the ring 14.

[0025] In this embodiment, as Figure 2As shown in the figure, a piston rod 9 is fixedly connected to the upper end surface of the lifting plate 10. The upper end of the piston rod 9 passes through and is slidably connected to the frame 8. The upper end of the piston rod 9 is fixedly connected to a cylinder 7, and the cylinder 7 is fixedly connected to the upper end surface of the frame 8. When the cylinder 7 is opened to drive the piston rod 9 to expand and contract, the lifting plate 10 can be driven to move up and down synchronously within the frame 8.

[0026] In this embodiment, as Figure 3 and Figure 4 shown in the figure, a sleeve 17 is sleeved on the outer surface of the stirring shaft 6. The sleeve 17 penetrates through the liquid storage tank 2. Vertical grooves 19 are symmetrically formed on the outer surface of the stirring shaft 6. The sleeve 17 is vertically slidably connected to the outer surface of the stirring shaft 6 through the vertical grooves 19. A plurality of stirring rods 18 are fixedly connected to the outer surface of the sleeve 17. When the stirring shaft 6 rotates, the sleeve 17 can be toggled through the vertical grooves 19 formed on the outer surface to drive the stirring rods 18 to rotate synchronously.

[0027] In this embodiment, as Figure 1 and Figure 4 shown in the figure, sliding rods 21 are symmetrically and fixedly connected to the upper end of the outer surface of the sleeve 17. A hollow column 5 is sleeved outside the sleeve 17. The hollow column 5 is fixedly connected to the upper end surface of the liquid storage tank 2. A reciprocating lifting groove 20 is formed on the inner wall of the hollow column 5. The ends of the sliding rods 21 away from the sleeve 17 are all slidably connected within the reciprocating lifting groove 20. When the sleeve 17 rotates, the sliding rods 21 on both sides can be driven to slide along the path of the reciprocating lifting groove 20 formed on the inner wall of the hollow column 5, and the sleeve 17 can be toggled to move up and down reciprocally synchronously during the horizontal rotation process.

[0028] The effects achieved by this embodiment are as follows: In the prior art, the stirring shaft 6 of the existing stirring and mixing device usually runs continuously for a long time. Long-term use will not only cause its wear to increase, shorten the service life of the equipment, and increase the maintenance cost, but also when stirring is not required, it often needs to be manually turned off by the staff, which not only increases the burden on the staff, but also causes the stirring shaft 6 to continue running when it is not needed, thus wasting energy and accelerating the wear and failure rate of the stirring shaft 6. Compared with the prior art, not only can the stirring shaft 6 be automatically opened to stir the liquid inside the liquid storage tank 2 before the liquid is input into the centrifuge 1, ensuring that the components in the liquid are fully mixed, avoiding precipitation or stratification phenomena, thereby improving the effect of subsequent centrifugation treatment and the accuracy of data, but also after the infusion stops, the stirring inside the liquid storage tank 2 can be automatically paused, reducing unnecessary energy consumption and reducing the unnecessary running time of the stirring shaft 6, thereby reducing the wear and failure rate of the stirring shaft 6, extending the service life of the equipment. At the same time, this design adopts automated control, effectively reducing the steps of manual operation and avoiding the cumbersome process of manually starting and stopping stirring, thus saving manpower and time.

[0029] The working process and principle involved in the overall content of the above embodiment are as follows:

[0030] When the staff needs to open the globe valve 4 and input the amino acid mixture inside the liquid storage tank 2 into the centrifuge 1 through the liquid inlet pipe 3 for extraction and separation, the staff first opens the air cylinder 7, driving the piston rod 9 to slide out from inside the frame 8 and pulling the lifting plate 10 inside the frame 8 to rise synchronously. During the rising process of the lifting plate 10, the lifting plate 10 will first drive the lever 15 on one side to move upward synchronously, causing the lever 15 to toggle the power switch 16 connected to the side wall of the frame 8. Since the power switch 16 is electrically connected to the stirring shaft 6, the stirring shaft 6 is turned on to rotate on the liquid storage tank 2. And during the process that the lifting plate 10 rises and drives the lever 15 to toggle the power switch 16, the ring 14 connected to the side wall of the lifting plate 10 will first slide upward on the outer surface of the stop rod 11 and approach the fixing plate 12 connected to the upper end of the stop rod 11. When the upper end surface of the ring 14 contacts the lower end surface of the stop rod 11, as the lifting plate 10 continues to rise inside the frame 8, the lifting plate 10 can drive the ring 14 to push the lower end surface of the fixing plate 12, lifting the stop rod 11 connected to the lower end surface of the fixing plate 12 out of the globe valve 4, thereby opening the valve core inside the globe valve 4, enabling the liquid in the liquid storage tank 2 to enter the centrifuge 1 through the liquid inlet pipe 3. Thus, before the liquid is input into the centrifuge 1, the stirring shaft 6 can be automatically turned on to stir the liquid inside the liquid storage tank 2, ensuring that the components in the liquid are fully mixed, avoiding precipitation or stratification phenomena, and thus improving the effect of subsequent centrifugation treatment and the accuracy of data;

[0031] When the power switch 16 is turned on to drive the stirring shaft 6 to rotate, the stirring shaft 6 can drive the sleeve 17 sleeved on its outer surface to rotate synchronously through the vertical groove 19 opened on the side wall, so that the stirring rod 18 connected to the outer surface of the sleeve 17 can stir and mix the liquid inside the liquid storage tank 2 before the globe valve 4 is opened. During the process that the sleeve 17 rotates following the stirring shaft 6, the sleeve 17 can drive the sliding rods 21 symmetrically connected to its outer surface to rotate horizontally synchronously, causing the other ends of the sliding rods 21 to slide in the reciprocating lifting groove 20 opened on the inner wall of the hollow column 5. And as the sliding rods 21 move along the path of the reciprocating lifting groove 20, the sliding rods 21 can cooperate with the vertical groove 19 opened on the outer surface of the stirring shaft 6 to drive the sleeve 17 to move up and down reciprocally synchronously during the horizontal rotation process. This design combines the up-and-down reciprocating movement and horizontal rotation of the stirring rod 18 to form a three-dimensional stirring effect, which can more comprehensively cover the liquid in the liquid storage tank 2, reduce the stirring dead angle, and make the components in the liquid mix evenly more quickly;

[0032] When the liquid injection inside the centrifuge 1 is completed, the staff can open the cylinder 7 again, push the piston rod 9 to slide into the frame 8, and push the lifting plate 10 connected to the lower end of the piston rod 9 to descend. As the lifting plate 10 descends, the ring 14 connected to the side wall of the lifting plate 10 will preferentially slide downward on the outer surface of the stop rod 11, close to the limit plate 13 connected to the outer surface of the stop rod 11, and after the ring 14 fits against the upper end surface of the limit plate 13, as the ring 14 continues to descend, the ring 14 will press the limit plate 13 downward, press the stop rod 11 into the stop valve 4, close the valve core inside the stop valve 4, and prevent the liquid from entering the centrifuge through the liquid inlet pipe 3. 1, in the process of the lifting plate 10 descending to close the stop valve 4, the lifting plate 10 can drive the lever 15 connected to the side wall to descend synchronously, and again toggle the power switch 16 connected to the side wall of the frame 8 to turn off the stirring shaft 6 connected to the liquid storage tank 2, so that after stopping the infusion, the stirring inside the liquid storage tank 2 can also be automatically suspended, reducing unnecessary energy consumption and unnecessary running time of the stirring shaft 6, thereby reducing the wear and failure rate of the stirring shaft 6 and extending the service life of the equipment. At the same time, the design adopts automated control, which effectively reduces the steps of manual operation and avoids the cumbersome process of manually starting and stopping stirring, thereby saving manpower and time.
