Description

Technical Field

[0001] This utility model relates to the field of centrifugal extractor technology, specifically to a high-efficiency and energy-saving centrifugal extractor. Background Technology

[0002] A centrifugal extractor is a rapid and efficient extraction device. It offers superior mixing and separation performance compared to conventional equipment. While conventional equipment struggles to mix systems with significant differences in specific gravity or viscosity, the centrifugal extractor's powerful mixing capability ensures thorough mixing of the two phases, facilitating easy reactions and mass transfer between them. Furthermore, it easily separates systems with small differences in specific gravity or high viscosity. This is because centrifugal extractors utilize centrifugal force, hundreds of times stronger than gravity, for separation.

[0003] Chinese patent CN118417064A discloses a centrifuge for achieving the effect of stratification of mixed solutions.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: In actual use, when centrifuging single-solution reagents, the reagents need to be symmetrically balanced before they can be used. However, in actual use, the balancing accuracy is affected by human error, which causes the high-speed centrifuge to rotate eccentrically. The vibration generated by the eccentric rotation reduces the kinetic energy transmission efficiency of the centrifuge.

[0005] This invention proposes a high-efficiency and energy-saving centrifugal extractor to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to enable the layering of mixed solutions through this device. The balancing component provides auxiliary balancing, thereby ensuring a more stable rotation process. At the same time, the movable shaft transmission structure effectively achieves stable rotation of the centrifuge shell while fine-tuning the horizontal position, thus avoiding eccentric rotation of the centrifuge shell, improving transmission efficiency, and overcoming the problems mentioned in the background art.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0008] A high-efficiency and energy-saving centrifugal extractor includes a shell and a control console connected to its top. A support column is fixedly connected to the top of the shell, a support ring is connected to the top of the support column, and a centrifugal shell is rotatably connected to the top of the support ring. A rotating component is provided inside the shell to drive the centrifugal shell to rotate, and a balancing component is provided at the bottom of the centrifugal shell to balance the rotation.

[0009] Further defining the above technical solution, the rotating component includes a rotating motor connected to the inner wall of the housing, a drive gear connected to the output end of the rotating motor, a driven gear meshing with the drive gear, the drive gear and the driven gear being rotatably connected to the inner wall of the housing, and a transmission shaft connected to the center of the driven gear. The rotational transmission stability of this device can be improved by means of gear transmission.

[0010] Further defining the above technical solution, the transmission shaft passes through the top of the housing, and the end of the transmission shaft away from the driven gear is connected to the transmission housing. A circular groove is provided at the center of the bottom of the inner wall of the transmission housing. The transmission housing structure can ensure that the subsequent connecting shaft and other structures are limited, thereby preventing the transmission process of this device from being interrupted.

[0011] Further defining the above technical solution, the inner arc surface of the circular groove at the bottom center of the inner wall of the transmission housing is provided with several transmission protrusions. A connecting shaft is slidably connected inside the circular groove, and a connecting part is fixedly connected to the outer arc surface of the connecting shaft inside the circular groove. The connecting part contacts the transmission protrusions. The combination of the connecting part and the transmission protrusions can ensure continuous and stable rotational transmission when the connecting shaft moves horizontally.

[0012] Further defining the above technical solution, the outer arc surface of the connecting shaft is rotatably connected to a rotating connecting member. The bottom of the rotating connecting member is slidably connected to the inner wall of the transmission housing. Several circumferentially distributed return springs are connected to the outer arc surface of the rotating connecting member. The other end of the return spring is connected to the side of the inner arc surface of the transmission housing. The top of the connecting shaft is connected to the bottom of the centrifugal housing. The return springs can ensure a centered rebound force on the connecting shaft, thereby preventing the connecting shaft from being too eccentric during rotational transmission.

[0013] Further defining the above technical solution, the balancing component includes several sliding shells that are circumferentially distributed at equal intervals and fixedly connected to the bottom of the centrifugal shell. A sliding spring is connected to the inner sidewall of each sliding shell, and a counterweight is connected to the other end of each sliding spring. The counterweight is slidably connected to the inner wall of the sliding shell. A sliding groove is provided at the bottom of the sliding shell, and a sliding limiting member is slidably provided on the inner wall of the sliding groove. The sliding limiting member is fixedly connected to the bottom of the counterweight. Through the effect of centrifugal force, the counterweight slides to different positions when the centrifugal shell rotates, thereby achieving a self-balancing effect.

[0014] Further defining the above technical solution, the diameter of the support ring is larger than the outer diameter of the centrifuge shell, and an annular blocking member is provided at the top of the support ring. There is a gap between the annular blocking member and the outer diameter of the centrifuge shell, and the maximum displacement of the centrifuge shell can be limited by the annular blocking member.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The rotational transmission effect is stable. The rotational transmission structure, which can be offset to a certain extent, can avoid eccentric vibration caused by the centrifugal shell not being fully balanced during actual use, thereby improving the kinetic energy conversion efficiency of this device.

[0017] 2. Automatic correction: The combination of sliding counterweight and return spring can automatically correct for slight tilting, ensuring stable centrifugal rotation. Attached Figure Description

[0026] The following is in conjunction with the instruction manual. Figure 1-6 This application will be described in further detail.

[0027] Reference Figure 1 and Figure 2 This application discloses a high-efficiency and energy-saving centrifugal extractor, including a housing 1 and a control console 2 connected to its top. A support column 3 is fixedly connected to the top of the housing 1, a support ring 4 is connected to the top of the support column 3, and a centrifugal housing 5 is rotatably connected to the top of the support ring 4. A rotating component 6 is provided inside the housing 1 to drive the centrifugal housing 5 to rotate, and a balancing component 7 is provided at the bottom of the centrifugal housing 5 to balance the rotation.

[0028] Refer to Figure 3 Figure 4 and Figure 5 The rotating component 6 includes a rotating motor 601 connected to the inner wall of the housing 1. A drive gear 602 is connected to the output end of the rotating motor 601. The drive gear 602 meshes with a driven gear 603. The drive gear 602 and driven gear 603 are rotatably connected to the inner wall of the housing 1. A drive shaft 604 is connected to the center of the driven gear 603. The drive shaft 604 passes through the top of the housing 1. The end of the drive shaft 604 away from the driven gear 603 is connected to a transmission housing 605. A circular groove is provided at the center of the bottom of the inner wall of the transmission housing 605. The inner arc surface of the circular groove at the center of the bottom of the inner wall of the transmission housing 605... The device has several transmission protrusions 606. A connecting shaft 608 is slidably connected inside a circular groove. A docking piece 607 is fixedly connected to the outer arc surface of the connecting shaft 608 inside the circular groove. The docking piece 607 contacts the transmission protrusions 606. A rotating connecting piece 609 is rotatably connected to the outer arc surface of the connecting shaft 608. The bottom of the rotating connecting piece 609 is slidably connected to the inner wall of the transmission housing 605. Several circumferentially distributed return springs 610 are connected to the outer arc surface of the rotating connecting piece 609. The other end of the return spring 610 is connected to the side of the inner arc surface of the transmission housing 605. The top of the connecting shaft 608 is connected to the bottom of the centrifugal housing 5.

[0029] By allowing the connecting shaft 608 to sway to a certain extent inside the circular groove, eccentric vibration of the device is avoided. Using a smaller degree of elliptical rotation trajectory instead of eccentric vibration can improve the kinetic energy transmission efficiency of the centrifugal shell 5 during rotational transmission.

[0030] Reference Figure 5 and Figure 6 The balancing component 7 includes several sliding shells 701 that are circumferentially distributed at equal intervals and are fixedly connected to the bottom of the centrifuge shell 5. A sliding spring 702 is connected to the inner side wall of the sliding shell 701, and a counterweight 703 is connected to the other end of the sliding spring 702. The counterweight 703 is slidably connected to the inner wall of the sliding shell 701. A sliding groove 704 is provided at the bottom of the sliding shell 701, and a sliding limiting member 705 is slidably provided on the inner wall of the sliding groove 704. The sliding limiting member 705 is fixedly connected to the bottom of the counterweight 703. The diameter of the support ring 4 is larger than the outer diameter of the centrifuge shell 5, and an annular blocking member is provided at the top of the support ring 4. There is a gap between the annular blocking member and the outer diameter of the centrifuge shell 5.

[0031] The structure of the balancing component 7 allows for sliding adjustment of the counterweights 703 at different positions when a small asymmetrical weight is generated, thereby achieving a balancing effect.

[0032] In summary, the high-efficiency and energy-saving centrifugal extractor disclosed in this application allows the solvent to be centrifuged to be placed inside the centrifugal housing 5 during use. Subsequently, the combination of the rotating motor 601 and gears drives the transmission shaft 604 to rotate at high speed.

[0033] During the rotational transmission process, the connecting shaft 608 extends into the circular groove inside the transmission housing 605. At this time, the transmission protrusion 606 contacts the mating part 607 to achieve the rotational transmission effect of the transmission shaft 604 on the connecting shaft 608. Meanwhile, since the outer diameter of the connecting shaft 608 is smaller than the inner diameter of the circular groove, the connecting shaft 608 can maintain the continuous rotational transmission connection while moving horizontally inside the circular groove to a certain extent.

[0034] Subsequently, by rotating the connection 609 and the return spring 610, the rotation limit effect of the connection shaft 608 can be achieved, so that after the rotation speed tends to stabilize, the connection shaft 608 tends to be located at the center of the circular groove during rotation.

[0035] The above structure avoids rigid vibration during eccentric rotation. The horizontal sway of the connecting shaft 608 maintains continuous rotational transmission while the return spring 610 reduces eccentric vibration.

[0036] Subsequently, during the high-speed rotation of the centrifugal shell 5, the centrifugal force enables multiple counterweights 703 to slide away from the centrifugal shell 5. When the contents inside the centrifugal shell 5 are not in a balanced state, the different degrees of sliding of the different counterweights 703 achieve an automatic balancing effect, thereby ensuring stable centrifugal rotation.
