Description

Technical Field

[0001] This utility model relates to a moving and stationary disk structure for a supergravity device, specifically a moving and stationary disk structure for a supergravity device with no residual liquid accumulation. Background Technology

[0002] Centrifugal devices achieve efficient mixing, separation, or reaction processes through centrifugal force generated by high-speed rotation. Their core components typically include a coaxially arranged moving disk and a stationary disk, with a ring-shaped moving coil structure on the surface of the moving disk to enhance mass transfer.

[0003] In existing technologies, the moving disc mostly adopts a horizontally arranged rigid disc structure, and the mounting surface of the moving ring is strictly perpendicular to the axis of rotation. During the gas-liquid two-phase operation, when the liquid phase component is subjected to centrifugal force and gathers towards the outer edge of the moving ring, it is easy to form a stagnation zone at the root of the moving ring. This causes local liquid accumulation to be unable to be discharged in time, and long-term liquid accumulation will corrode the root of the moving ring, thereby affecting the service life of the overall equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a structure for the moving and stationary discs of a supergravity device that leaves no residual liquid.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a rotating shaft, a moving disk, a stationary disk, a moving ring, and a stationary ring. The moving disk is disposed on the rotating shaft and is opposite to the stationary disk. Multiple moving rings of different diameters are sequentially disposed on the moving disk. Multiple stationary rings are disposed on the stationary disk and are opposite to the moving rings. The moving disk is inclinedly disposed on the rotating shaft. Multiple drain holes are provided on the moving disk and the drain holes are adjacent to the moving rings.

[0006] By adopting the above technical solution, after the equipment stops, due to the tilted setting of the moving plate, the residual liquid at the root of the moving coil will automatically flow to a lower position along the surface of the tilted moving plate under the action of gravity, and be completely discharged through the drain hole adjacent to the moving coil without manual intervention; it completely eliminates the residual liquid at the root of the moving coil after shutdown, avoiding long-term corrosion of key components by corrosive liquid; it greatly reduces the cleaning workload during equipment maintenance and improves operating efficiency; the structure is simple and reliable, with no additional energy consumption, and is suitable for frequent start-stop conditions.

[0007] The present invention is further configured such that: the moving disc is convex, and the drain hole is located on the side of the moving ring that is relatively close to the rotating shaft, and is convex, that is, the center is high and the edge is low.

[0008] By adopting the above technical solution, the center of the moving plate is higher than the edge. After the machine stops, the liquid remaining at the root of the moving ring flows from the high point of the center to the low point of the edge under the action of gravity. Finally, it is discharged through the drain hole located on the side of the moving ring near the rotating shaft. The high center and low edge cause the liquid to flow outward until it comes into contact with the moving ring, and is then discharged through the drain hole near the moving ring.

[0009] The present invention is further configured to include a shim ring, the moving plate is concave, the drain hole is located on the side of the moving ring that is relatively far from the rotating shaft, the shim ring is set on the rotating shaft and located on the moving plate, the diameter of the shim ring is smaller than the diameter of the moving ring, and the moving plate is provided with a drain hole opposite to the shim ring, the concave type, that is, the center is low and the edge is high.

[0010] By adopting the above technical solution, the center of the moving plate is lower than the edge. After the machine stops, the accumulated liquid flows from the high point of the edge to the low point of the center under the action of gravity and is discharged through the drain hole located on the side of the moving plate away from the rotating shaft. The purpose of setting the shim ring is to prevent the accumulated liquid from accumulating in the center, thereby raising the central area so that the accumulated liquid flows to the shim ring and then flows out from the drain hole.

[0011] The present invention is further configured such that the angle between the moving plate and the horizontal plane is 1-2 degrees.

[0012] The present invention is further configured such that the diameter of the drain hole is 1-3 mm.

[0013] The present invention is further configured such that the distance between the drain hole and the moving coil is 1mm-2mm. Attached Figure Description

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figure 1-3 As shown, this utility model discloses a structure for a rotating and stationary disk of a gravity device that eliminates residual liquid accumulation. It includes a rotating shaft 1, a rotating disk 2, a stationary disk 3, a rotating ring 4, and a stationary ring 5. The rotating disk 2 is mounted on the rotating shaft 1 and faces the stationary disk 3. Multiple rotating rings 4 of different diameters are sequentially mounted on the rotating disk 2. Multiple stationary rings 5 ​​are mounted on the stationary disk 3 and face the rotating rings 4. The rotating disk 2 is tilted on the rotating shaft 1. Multiple drainage holes 6 are provided on the rotating disk 2 and are adjacent to the rotating rings 4. After the device stops, due to the tilted arrangement of the rotating disk 2, the residual liquid at the base of the rotating rings 4 is discharged. Under the influence of gravity, the liquid automatically flows down the inclined moving plate 2 and is completely discharged through the drain hole 6 adjacent to the moving coil 4 without manual intervention; it completely eliminates the residual liquid at the root of the moving coil 4 after shutdown, preventing corrosive liquid from corroding key components for a long time; it greatly reduces the cleaning workload during equipment maintenance and improves operating efficiency; the structure is simple and reliable, with no additional energy consumption, and is suitable for frequent start-stop conditions. It should be noted that the stationary plate 3 is fixed to the machine body, and the machine body and the motor that drives the rotating shaft 1 are very mature technologies, so they will not be described further.

[0021] The moving plate 2 is convex, and the drain hole 6 is located on the side of the moving coil 4 that is relatively close to the rotating shaft 1. The convex shape means that the center is high and the edge is low. The center of the moving plate 2 is higher than the edge. After the machine stops, the liquid remaining at the root of the moving coil 4 flows from the high point of the center to the low point of the edge under the action of gravity. Finally, it is discharged through the drain hole 6 located on the side of the moving coil 4 that is close to the rotating shaft 1. The high center and low edge cause the liquid to flow outward until it comes into contact with the moving coil 4, and then is discharged through the drain hole 6 near the moving coil 4.

[0022] It also includes a shim ring 7. The moving plate 2 is concave. The drain hole 6 is located on the side of the moving ring 4 that is relatively far away from the rotating shaft 1. The shim ring 7 is set on the rotating shaft 1 and located on the moving plate 2. The diameter of the shim ring 7 is smaller than the diameter of the moving ring 4. The moving plate 2 is provided with a drain hole 8 opposite to the shim ring 7. It is concave, that is, the center is low and the edge is high. The center of the moving plate 2 is lower than the edge. After the machine stops, the accumulated liquid flows from the high point of the edge to the low point of the center under the action of gravity and is discharged through the drain hole 6 located on the side of the moving ring 4 that is far away from the rotating shaft 1. The purpose of setting the shim ring 7 is to prevent the accumulated liquid from accumulating in the center, thereby raising the central area so that the accumulated liquid flows to the shim ring 7 and then flows out from the drain hole 8.

[0023] The angle between the moving plate 2 and the horizontal plane is 1-2 degrees, the diameter of the drain hole 6 is 1-3mm, and the distance between the drain hole 6 and the moving ring 4 is 1mm-2mm.

[0024] Example 1: After the equipment stops rotating, the liquid remaining at the root of the moving coil 4 flows along the inclined surface to the lower edge due to the curved surface structure of the moving disk 2, which is high at the center and low at the edge, under the action of gravity; when the liquid flows to the point of contact with the moving coil 4, it is discharged by the drain hole 6.

[0025] Example 2: After the equipment stops rotating, the liquid remaining at the root of the moving coil 4 flows towards the center along the inclined surface under the action of gravity due to the curved surface structure of the moving plate 2, which has a low center and high edge. When the liquid flows to the point of contact with the moving coil 4, it is discharged by the drain hole 6. The liquid in the innermost layer of the moving coil 4 flows to the padding ring 7 and is then discharged by the drain hole 8.
