Description

Technical Field

[0001] This invention belongs to the field of centrifuge technology, specifically, it relates to an ultrafine fiber centrifuge. Background Technology

[0002] An ultrafine fiber centrifuge is a specialized device that uses centrifugal force generated by high-speed rotation (thousands to tens of thousands of rpm) to prepare or classify ultrafine fibers (micron to nanometer scale). It mainly consists of a drive system, a rotor with nozzles / filter holes, a raw material supply module, a collection / separation component, and a control system. There are two types: centrifugal spinning type (focusing on fiber forming, suitable for the preparation of non-woven fabrics, medical stents, and other materials) and centrifugal separation type (focusing on fiber purification, suitable for raw material refining). It features high efficiency and high output, controllable fiber morphology, and compatibility with multiple raw material systems, and is widely used in materials textiles, biomedicine, environmental filtration, and other fields.

[0003] In the process of producing and preparing microfibers, the raw fiber system is prone to being mixed with inorganic impurities, high molecular weight coarse fibers, mechanical debris and other foreign matter. Since these impurities and coarse fibers have significant differences in density parameters from the target microfibers, centrifugal separation technology has become the core process for purifying and refining microfibers based on the density sieving principle.

[0004] The purification process requires first uniformly dispersing the ultrafine fiber raw material to be treated in a suitable solvent or suspension medium. A stable and uniformly dispersed fiber suspension system is constructed through pretreatment methods such as stirring and ultrasound to ensure that the fiber and impurities are fully dissociated in the system. Then, the suspension system is injected into the centrifuge chamber. After the equipment is started, the centrifuge's built-in drive mechanism drives the rotor assembly to perform high-speed circular motion. Under the action of centrifugal force field, the denser impurities and coarse-diameter fibers settle radially outward to the inner wall of the rotor, while the less dense target ultrafine fibers are enriched in the upper layer of the suspension, thereby achieving efficient separation of the two and fiber purification.

[0005] Currently, most mainstream centrifugal separation equipment on the market adopts a top-opening structure design for ultrafine fiber purification applications. The feeding operation requires opening the top cover of the equipment and injecting the fiber suspension system into the cavity through the top feed port. After the centrifugation purification process is completed, the material still needs to be taken out and collected through the top opening.

[0006] While this top-in, top-out operating mode can meet basic operational needs when applied to small and medium-sized laboratory centrifuges, it has significant operational limitations and efficiency bottlenecks in industrial-scale production scenarios, particularly for large and ultra-large centrifuges with large processing capacities. When discharging from the top, the deep cavity of large equipment makes it difficult and time-consuming to remove the material, directly resulting in low discharge efficiency of ultrafine fibers. Summary of the Invention

[0007] The purpose of this invention is to provide an ultrafine fiber centrifuge that solves the technical problem in related technologies where the material is difficult to remove and takes a long time to be removed due to the deep cavity of the large equipment, which directly leads to low discharge efficiency of ultrafine fibers.

[0008] At least one embodiment of the present invention provides an ultrafine fiber centrifuge device, including a centrifuge cylinder and a rotating drum, the rotating drum being located inside the centrifuge cylinder. A top cover is hinged to the top of the centrifuge cylinder. The device also includes a side plate, a drive rod, and a swing ring. A discharge port is provided on the centrifuge cylinder. The side plate is disposed at the discharge port by a locking mechanism, which supports the side plate in opening and closing at the discharge port. The drive rod is rotatably connected to the inner wall of the centrifuge cylinder. The rotating drum is rotatably connected to the top of the drive rod. A drive mechanism is provided at the bottom of the centrifuge cylinder to drive the drive rod to rotate. The swing ring is rotatably connected to the bottom of the rotating drum. A swing mechanism is installed inside the centrifuge cylinder to drive the swing ring and the rotating drum to tilt at the top of the drive rod.

[0009] To drive the drum to tilt and swing during discharge, causing it to flip towards the discharge port for easier material discharge by the operator, the swing mechanism includes: a connecting frame, a swing frame, a rotating gear, and a power assembly. The connecting frame is fixedly connected to one side of the swing ring, and the swing frame is rotatably connected to the inner wall of the centrifuge cylinder. One end of the swing frame is rotatably connected to the connecting frame, and the rotating gear is fixedly connected to the other end of the swing frame. The power assembly is mounted on the centrifuge cylinder and is used to drive the rotating gear and the swing frame to rotate.

[0010] To drive the rotating gear to rotate, the power assembly includes a gear plate and an electric cylinder. The gear plate is slidably connected to one side of the centrifuge cylinder and meshes with the rotating gear. The electric cylinder is installed on one side of the centrifuge cylinder and its output end is fixedly connected to the top of the gear plate.

[0011] In order to drive the drive rod and the drum to rotate, the drive mechanism includes: a drive wheel, a drive belt and a motor. There are two drive wheels, one of which is fixedly connected to the bottom end of the drive rod. The drive belt is connected between the two drive wheels. The motor is installed on one side of the centrifuge cylinder and the output end of the motor is fixedly connected to the other drive wheel.

[0012] In order to control the opening and closing of the side plate and facilitate the discharge of material from the drum at the discharge port, the locking mechanism includes: a fixed seat, a rotating block and a latch lock. There are two fixed seats, both of which are fixedly connected to one side of the centrifuge drum. A rotating block is rotatably connected inside each of the two fixed seats. Both rotating blocks are fixedly connected to the side plate. The latch lock is installed on the side plate and the centrifuge drum.

[0013] To increase the sealing between the side plate and the discharge port, a sealing strip is fixedly connected to the discharge port, and the inner wall of the side plate contacts the sealing strip when the side plate is closed.

[0014] To support the drum's swinging motion at the top of the drive rod, a connecting seat is fixedly connected to the top of the drive rod, and a connecting block is rotatably connected inside the connecting seat. The top of the connecting block is fixedly connected to the drum.

[0015] To increase the stability of the drum as it rotates on the swing ring, a fixed ring is fixedly connected to the bottom end of the drum, and the swing ring is rotatably connected to the circumferential surface of the fixed ring.

[0016] The present invention provides an ultrafine fiber centrifuge device. When discharging ultrafine fibers, the side door is opened and the drum is driven to rotate by a swing mechanism, so that the opening of the drum faces the discharge port, which makes it convenient for the operator to discharge the ultrafine fibers in the drum. The material is easier to remove and takes less time, thus improving the discharge efficiency of ultrafine fibers. Attached Figure Description

[0026] like Figures 1-7 The diagram illustrates an ultrafine fiber centrifuge according to an embodiment of the present invention, comprising a centrifuge cylinder 1 and a rotating drum 2. The rotating drum 2 is located inside the centrifuge cylinder 1. A top cover 3 is hinged to the top of the centrifuge cylinder 1. The centrifuge cylinder 1 also includes a side plate 4, a drive rod 5, and a swing ring 6. A connecting seat 19 is fixedly connected to the top of the drive rod 5, and a connecting block 20 is rotatably connected within the connecting seat 19. The top of the connecting block 20 is fixedly connected to the rotating drum 2. To support the rotating drum 2 in swinging motion on the drive rod 5, a discharge port is provided on the centrifuge cylinder 1, allowing the rotating drum 2 to tilt towards the discharge port for easy discharge of ultrafine fibers from the rotating drum 2. The side plate 4 is positioned at the discharge port via a locking mechanism, which supports the side plate. Plate 4 opens and closes at the discharge port. Drive rod 5 is rotatably connected to the inner wall of centrifuge cylinder 1. Drum 2 is rotatably connected to the top of drive rod 5. A drive mechanism is provided at the bottom of centrifuge cylinder 1 to drive drive rod 5 to rotate. Swing ring 6 is rotatably connected to the bottom of drum 2. Swing mechanism is installed inside centrifuge cylinder 1. Swing mechanism is used to drive swing ring 6 and drum 2 to tilt at the top of drive rod 5. When discharging ultrafine fibers, the side door is opened, and drum 2 is driven to rotate through swing mechanism, so that the opening of drum 2 faces the discharge port, which makes it convenient for operators to discharge ultrafine fibers in drum 2. The material is easier to remove and takes less time, thus improving the discharge efficiency of ultrafine fibers.

[0027] The oscillation mechanism includes: a connecting frame 7, an oscillation frame 8, a rotating gear 9, and a power assembly. A fixed ring 21 is fixedly connected to the bottom end of the drum 2. The oscillation ring 6 is rotatably connected to the circumferential surface of the fixed ring 21, which increases the stability of the oscillation ring 6 when rotating on the drum 2. The connecting frame 7 is fixedly connected to one side of the oscillation ring 6, allowing the connecting frame 7 to drive the oscillation ring 6 and the drum 2 to oscillate under force, thus facilitating the tilting and oscillation of the drum 2. The oscillation frame 8 is rotatably connected to the inner wall of the centrifuge cylinder 1. One end of the oscillation frame 8 is rotatably connected to the connecting frame 7, and the rotating gear 9 is fixedly connected to the other end of the oscillation frame 8. The power assembly is mounted on the centrifuge cylinder 1 and is used to drive the rotating gear 9 and the oscillation frame 8 to rotate. The power assembly includes: a toothed plate 10. The electric cylinder 11 and the toothed plate 10 are slidably connected to one side of the centrifuge drum 1. The toothed plate 10 meshes with the rotating gear 9. The electric cylinder 11 is installed on one side of the centrifuge drum 1. The output end of the electric cylinder 11 is fixedly connected to the top of the toothed plate 10. After the side plate 4 is opened, it is necessary to tilt the drum 2 so that the opening of the drum 2 faces the discharge port. The electric cylinder 11 drives the toothed plate 10 to move upward. When the toothed plate 10 moves upward, it meshes with the rotating gear 9, thereby driving the swing frame 8 to rotate. When the swing frame 8 rotates, it drives the connecting frame 7 and the swing ring 6 to flip, thereby driving the drum 2 to flip on the drive rod 5, so that the opening of the drum 2 faces the discharge port, making it convenient for the operator to discharge the ultrafine fibers in the deeper part of the drum 2.

[0028] The drive mechanism includes a drive wheel 12, a drive belt 13, and a motor 14. There are two drive wheels 12, one of which is fixedly connected to the bottom end of the drive rod 5. The drive belt 13 is driven between the two drive wheels 12. The motor 14 is installed on one side of the centrifuge cylinder 1. The output end of the motor 14 is fixedly connected to the other drive wheel 12. When centrifuging the ultrafine fibers in the drum 2, the motor 14 drives the drive wheel 12 to rotate. The drive belt 13 drives the other drive wheel 12 to rotate. When the other drive wheel 12 rotates, it drives the drive rod 5 to rotate. When the drive rod 5 rotates, it drives the drum 2 to rotate, thereby centrifuging the ultrafine fibers in the drum 2.

[0029] The locking mechanism includes: a fixed seat 15, a rotating block 16, and a latch lock 17. There are two fixed seats 15, both of which are fixedly connected to one side of the centrifuge cylinder 1. The rotating block 16 is rotatably connected inside each of the two fixed seats 15. The two rotating blocks 16 are fixedly connected to the side plate 4. The latch lock 17 is installed on the side plate 4 and the centrifuge cylinder 1. When the drum 2 rotates to centrifuge the ultrafine fibers, the side plate 4 is locked by the latch lock 17, thereby sealing the centrifuge cylinder 1 and preventing the ultrafine fibers from splashing out of the centrifuge cylinder 1 during centrifugal rotation. A sealing strip 18 is fixedly connected to the discharge port. When the side plate 4 is closed, the inner wall of the side plate 4 contacts the sealing strip 18. When the side plate 4 is closed, the side plate 4 contacts the sealing strip 18, thereby improving the sealing performance of the centrifuge cylinder 1.

[0030] Working principle: When centrifugal purification of ultrafine fibers is required, the top cover 3 is opened, and the ultrafine fibers are added into the drum 2. The top cover 3 is then closed. The motor 14 drives the drive wheel 12 to rotate, and a drive belt 13 transmits power between the two drive wheels 12, thus driving the other drive wheel 12 to rotate. The rotation of the other drive wheel 12 drives the drive rod 5 to rotate, which in turn drives the drum 2 to rotate, thereby centrifuging the ultrafine fibers inside the drum 2. After centrifugation of the ultrafine fibers is complete, the operator opens the latch lock 17. Then, the electric cylinder 11 moves the toothed plate 10 upwards. When in motion, the toothed plate 10 meshes with the rotating gear 9, thereby driving the swing frame 8 to rotate. When the swing frame 8 rotates, it drives the connecting frame 7 and the swing ring 6 to flip, thereby driving the drum 2 to flip on the drive rod 5, so that the opening of the drum 2 faces the discharge port, making it convenient for the operator to discharge the ultrafine fibers from the deeper part of the drum 2. After the ultrafine fibers are discharged, the electric cylinder 11 drives the toothed plate 10 to move in the opposite direction. When the toothed plate 10 moves in the opposite direction, it drives the rotating gear 9 to rotate in the opposite direction, thereby driving the swing frame 8 to rotate in the opposite direction, so that the drum 2 returns to the vertical position, closes the side plate 4, and locks the latch lock 17, so that the drum 2 can perform centrifugation operation on the subsequent ultrafine fibers.

[0031] It should also be noted that when the drum 2 is rotating in the vertical position, the swing ring 6 does not rotate. At this time, the fixed ring 21 rotates within the swing ring 6, thereby supporting the drum 2 to rotate stably. In addition, when the drum 2 flips, it rotates around the center point of the connecting block 20 rotating within the connecting seat 19. Therefore, it is necessary to adjust the angle of the connecting seat 19 so that when the connecting block 20 rotates within the connecting seat 19, the drum 2 swings towards the discharge port.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
