Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to an anti-drip centrifuge. Background Art

[0002] Centrifuges use centrifugal force to achieve efficient separation of solid and liquid materials and are widely used in industry.

[0003] In conventional centrifuges, the hub is rotatably mounted within the drum. During centrifugation, material is placed into the hub and then rotated. Liquid within the material flows through the holes in the hub, passing through the hub and into the gap between the hub and the drum. After centrifugation is complete, the centrifuged material is discharged through a discharge port at the bottom of the hub.

[0004] However, during the centrifugal dehydration process of the equipment, a mixture of liquid and material drips from the discharge port, causing pollution to the discharge port and the following structures, affecting product quality. Utility Model Content

[0005] In view of this, the utility model provides an anti-drip centrifuge, which can prevent the occurrence of dripping and improve the quality of the material after centrifugation.

[0006] The utility model provides an anti-drip centrifuge, comprising a rotating hub and a cylinder, wherein the rotating hub is rotatably arranged in the cylinder, a gap is formed between the bottom plate of the rotating hub and the bottom plate of the cylinder, a spoiler is formed on the side of the bottom plate of the rotating hub facing the gap, and the spoiler extends from the center of the rotating hub to the edge of the rotating hub.

[0007] Furthermore, there are a plurality of spoilers, and the plurality of spoilers are arranged at the bottom of the hub along the circumference of the hub.

[0008] Furthermore, the spoiler extends along the radial direction of the hub.

[0009] Furthermore, the spoiler extends along a straight line, and a tangent line at an intersection of the extension line of the spoiler and the edge of the hub forms an angle not equal to 90° with the straight line where the spoiler is located.

[0010] Furthermore, the spoiler extends in a straight line, and the angle between the tangent line at the intersection of the extension line of the spoiler and the edge of the hub and the spoiler is 45-90°.

[0011] Furthermore, the entire spoiler or the end portion away from the center of the hub extends in an arc shape.

[0012] Furthermore, a discharge port is formed at the bottom of the rotating hub, a first convex ring protruding downward is formed at the edge of the discharge port, a discharge hole is formed at a position corresponding to the discharge port at the bottom of the cylinder, the first convex ring extends into the discharge hole, and a second convex ring protruding upward is formed at the edge of the discharge hole, when the rotating hub is installed in the cylinder, the second convex ring is located between the spoiler and the first convex ring.

[0013] Furthermore, the distance between one end of the spoiler facing the center of the hub and the second protruding ring is 10-15 mm.

[0014] Furthermore, the length of the spoiler is 40-50 mm.

[0015] Furthermore, the thickness of the spoiler is 5-10 mm.

[0016] Furthermore, the anti-drip centrifuge also includes a feed pipe, which is fixed on the cylinder and has an end portion extending into the rotating hub.

[0017] Furthermore, the anti-drip centrifuge also includes a scraper, which includes a telescopic rod and a cutter head. The telescopic rod is fixed to the top of the cylinder, and its end extends into the rotating hub. The cutter head is arranged on one end of the telescopic rod extending into the rotating hub.

[0018] Furthermore, a liquid discharge port is formed at the bottom of the cylinder.

[0020] In summary, the present invention provides a spoiler extending from the center of the hub to the edge of the hub. When the hub rotates, the spoiler rotates along with the hub. When the spoiler rotates, it acts like a fan blade, disturbing the air in the gap so that the air in the gap moves away from the center of the hub. The flow of air can also have an outflow effect on the liquid in the gap, preventing the liquid from flowing out of the assembly gap between the hub and the cylinder. Therefore, the anti-drip centrifuge can prevent the occurrence of dripping and improve the quality of the material after centrifugation.

[0021] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In addition, in order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

[0027] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description with reference to the accompanying drawings and preferred embodiments.

[0028] The utility model provides an anti-drip centrifuge, which can prevent the occurrence of dripping and improve the quality of centrifuged materials.

[0029] Figure 1 FIG. 1 is a schematic cross-sectional view of the anti-drip centrifuge provided by an embodiment of the present invention. Figure 2 Shown Figure 1 Schematic diagram of the shaft side structure of the transfer hub, Figure 3 Shown Figure 2 Schematic diagram of the transfer hub structure from an upward perspective. Figures 1 to 3 As shown, the drip-proof centrifuge provided by the embodiment of the present invention includes a rotor hub 10 and a cylinder 20. The rotor hub 10 is rotatably arranged in the cylinder 20. A gap 30 is formed between the bottom plate of the rotor hub 10 and the bottom plate of the cylinder 20. A spoiler 40 is formed on the bottom plate of the rotor hub 10 facing the side of the gap 30. The spoiler 40 extends from the center of the rotor hub 10 to the edge of the rotor hub 10.

[0030] Since the hub 10 needs to rotate within the barrel 20, a gap 30 must exist between the hub 10 and the barrel 20 during installation. When the hub 10 rotates and the material is discharged, negative pressure will exist near the discharge port. In this embodiment, a spoiler 40 is provided that extends from the center of the hub 10 to the edge of the hub 10. When the hub 10 rotates, the spoiler 40 rotates with the hub 10. When the spoiler 40 rotates, it has an effect similar to that of a fan blade, disturbing the air in the gap 30 so that the air in the gap 30 moves away from the center of the hub 10. The flow of air can also have an outward discharge effect on the liquid in the gap 30, preventing the liquid from flowing out of the assembly gap between the hub 10 and the barrel 20. Therefore, the anti-drip centrifuge can prevent the occurrence of dripping and improve the quality of the material after centrifugation.

[0031] For further information, please refer to Figure 2 and Figure 3 In this embodiment, multiple spoilers 40 may be provided, arranged on the bottom of the hub 10 along the circumference of the hub 10. The provision of multiple spoilers 40 allows for better air drainage during rotation, further preventing leakage. This embodiment illustrates a configuration in which four spoilers 40 are evenly distributed on the bottom of the hub 10 along the circumference of the hub 10. It is understood that in other embodiments, two, three, or more spoilers 40 may be provided.

[0032] Furthermore, in this embodiment, a feed opening 11 is formed at the bottom of the hub 10 (see FIG. Figure 2 ), a first convex ring 12 protruding downward is formed on the edge of the discharge port 11. A discharge hole 21 is formed at the bottom of the cylinder 20 at a position corresponding to the discharge port 11, and the first convex ring 12 extends into the discharge hole 21. A second convex ring 22 protruding upward is formed on the edge of the discharge hole 21. When the hub 10 is installed in the cylinder 20, the second convex ring 22 is located between the spoiler 40 and the first convex ring 12. Through the arrangement of the first convex ring 12 and the second convex ring 22 and the layout relationship between the two positions, the liquid in the gap 30 can be further blocked to reduce the occurrence of dripping. It can be understood that the above-mentioned assembly gap between the hub 10 and the cylinder 20 exists between the first convex ring 12 and the second convex ring 22.

[0033] Furthermore, the distance between the end of the spoiler 40 facing the center of the hub 10 and the second protruding ring 22 is 10-15 mm. The length of the spoiler 40 is 40-50 mm. The thickness of the spoiler can be 5-10 mm.

[0034] Furthermore, in this embodiment, the spoiler 40 extends in the radial direction of the hub 10. That is, the spoiler 40 extends along a straight line, and the tangent line at the intersection of the extension line of the spoiler 40 and the edge of the hub 10 is perpendicular to the straight line where the spoiler 40 is located (i.e. Figure 3 where α is 90°).

[0035] More specifically, the anti-drip centrifuge also includes a feed pipe 51 and a scraper 52. The feed pipe 51 is fixed to the cylinder 20, and its end extends into the rotating hub 10 to feed the centrifuge. The scraper 52 includes a telescopic rod 521 and a blade head 522. The telescopic rod 521 is fixed to the top of the cylinder 20, and its end extends into the rotating hub 10. The blade head 522 is located on the end of the telescopic rod 521 that extends into the rotating hub 10.

[0036] A filter cloth (not shown) is also provided on the inner side wall of the hub 10 to facilitate collection of materials while allowing liquid to pass through.

[0037] An exhaust port 23 is formed on the side wall of the cylinder 20 to discharge gas. A liquid discharge port 24 is formed at the bottom of the cylinder 20 to discharge liquid in the gap 30 between the cylinder 20 and the hub 10.

[0038] Please continue to refer to Figure 1 In this embodiment, the projection of the end of the spoiler 40 close to the center of the hub 10 toward the bottom of the cylinder 20 falls between the drain port 24 and the second protruding ring 22. This prevents the spoiler 40 from affecting the normal drainage when the hub 10 rotates.

[0039] Figure 4 The figure shows a bottom view of the structure of the anti-drip centrifuge hub provided by the second embodiment of the present invention. Figure 4 As shown, the anti-drip centrifuge provided by the second embodiment of the present invention is basically the same as the first embodiment, except that, in this embodiment, the spoiler 40 extends along a straight line, but no longer extends along the radial direction of the hub 10. The tangent line at the intersection of the extension line of the spoiler 40 and the edge of the hub 10 forms an angle not equal to 90 degrees with the spoiler 40 (i.e. Figure 4 (where α is not equal to 90°).

[0040] More specifically, the angle between the tangent line at the intersection of the extension line of the spoiler 40 and the edge of the hub and the spoiler 40 is 45-90°.

[0041] Figure 5FIG2 is a bottom view of the hub 10 of a drip-proof centrifuge according to a third embodiment of the present invention. The drip-proof centrifuge according to the third embodiment is substantially the same as the aforementioned embodiments, except that, in this embodiment, the spoiler 40 no longer extends in a straight line. Instead, the entire spoiler 40 or the end thereof away from the center of the hub 10 extends in an arc shape.

[0042] In summary, the present invention provides a spoiler 40 extending from the center of the hub 10 to the edge of the hub 10. When the hub 10 rotates, the spoiler 40 rotates along with the hub 10. When the spoiler 40 rotates, it acts like a fan blade, disturbing the air in the gap 30 so that the air in the gap 30 moves away from the center of the hub 10. The flow of air can also have an outflow effect on the liquid in the gap 30, preventing the liquid from flowing out of the assembly gap between the hub 10 and the cylinder 20. Therefore, the anti-drip centrifuge can prevent the occurrence of dripping and improve the quality of the material after centrifugation.

Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
