Description

Technical Field

[0001] This application relates to the field of centrifugal separation, and in particular to a centrifuge disc with adjustable neutral pores. Background Technology

[0002] A disc centrifuge is a purification and separation machine that utilizes the principle that light and heavy liquid phases and solid phases with different densities and incompatible properties in a mixture have different settling velocities under centrifugal force, thereby achieving the purpose of separation and stratification or causing solid particles to settle.

[0003] Typical disc centrifuges currently on the market are shown in the attached image. Figure 1 As shown, the main components affecting the separation performance of a disc centrifuge include the drum, discs, light-phase centrifugal pump, and heavy-phase centrifugal pump, among which the disc is the most crucial component. Under centrifugal force, the heavy phase liquid moves outward along the disc and flows out through the heavy phase channel, while the light phase liquid moves inward along the disc and flows out through the light phase channel. Due to their immiscibility and continuous flow, a separation interface forms between the light and heavy phases inside the disc. This interface significantly impacts the centrifuge's separation accuracy, and the matching of the neutral pore distribution on the disc with the interface position determines the centrifuge's separation accuracy and operational stability. Therefore, the design of the neutral pores is of paramount importance in disc design.

[0004] During the development of new products, it is necessary to produce disc prototypes based on the design results and verify the rationality of the disc design through testing.

[0005] Regarding the aforementioned technologies, the inventors believe that disc centrifuges contain a large number of discs, typically around 200. If a set of discs is produced for each design and tested, it would have a significant negative impact on both economic costs and development cycle. Summary of the Invention

[0006] To improve the compatibility of centrifuge discs and reduce the need to produce corresponding discs for different design schemes, this application provides a centrifuge disc with adjustable neutral orifice.

[0007] This application provides a centrifuge disc with an adjustable neutral pore, employing the following technical solution:

[0008] A centrifuge disc with an adjustable neutral orifice includes a mother disc with a horizontally formed channel hole. An adjusting plate is positioned on the mother disc relative to the channel hole. An assembly is provided between the mother disc and the adjusting plate, and the assembly mounts the adjusting plate onto the mother disc. The adjusting plate has a neutral orifice opposite to the channel hole.

[0009] Optionally, the length of the channel hole along the height direction is greater than the length of the neutral hole along the height direction, and the neutral hole is opened at the end opposite to the channel hole or at the center of the channel hole.

[0010] Optionally, the width of the neutral hole is the same as the width of the channel hole.

[0011] Optionally, the width of the neutral hole is smaller than the width of the channel hole.

[0012] Optionally, the neutral hole is a waist-shaped hole.

[0013] Optionally, the channel hole is an oblong hole.

[0014] Optionally, the mounting assembly includes a positioning block located on the side of the female disc opposite to the channel hole, the positioning block having a positioning groove, and a locking block fixedly connected to the position of the adjusting piece relative to the positioning groove, the locking block being able to extend into the interior of the positioning groove.

[0015] Optionally, the thickness of the card block is the same as the spacing between two adjacent master discs, and the thickness of the adjustment piece is less than the thickness of the card block.

[0016] Optionally, multiple positioning blocks are arranged opposite each other on both sides of the channel hole, and the multiple positioning blocks are arranged symmetrically about the center position of the channel hole.

[0017] Optionally, the thickness of the card block is 1 mm, and the thickness of the adjusting piece is 0.3 mm.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By combining master discs and adjusting plates, and keeping the master disc unchanged, the experimental effects of multiple disc structure schemes can be quickly verified by producing adjusting plates of different specifications.

[0020] 2. Due to the small size, simple structure, and superior processing performance of the adjustment plate, only one master disc needs to be produced during the development of the new prototype. With the help of several sets of adjustment plates, the design optimization process of the disc structure can be realized, thereby greatly reducing the production cost and development cycle of the disc.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0030] The following is in conjunction with the appendix Figures 2-6 This application will be described in further detail.

[0031] This application discloses a centrifuge disc with an adjustable neutral pore. (See also...) Figure 2 , Figure 3 A centrifuge disc with adjustable neutral hole includes a mother disc 2, which has a trapezoidal structure and a horizontal channel hole 21 on the mother disc 2. The channel hole 21 completely penetrates the mother disc 2. The channel hole 21 is an oblong hole, and the long axis of the channel hole 21 is set along the vertical direction.

[0032] Reference Figure 3An adjusting plate 3 is vertically mounted on the mother disc 2 relative to the channel hole 21. The adjusting plate 3 is mounted on the mother disc 2 via the mounting assembly 4, and the adjusting plate 3 is opposite to the channel hole 21. A neutral hole 31 is horizontally opened on the adjusting plate 3, which completely penetrates the adjusting plate 3. The neutral hole 31 is positioned opposite to the channel hole 21, allowing liquid to pass through the neutral hole 31 and enter the interior of the channel hole 21.

[0033] Refer to 4. Figure 5 , Figure 6 The neutral orifice 31 can be located at different positions opposite to the channel orifice 21 according to different experimental requirements. In one embodiment, the neutral orifice 31 is located at one end of the channel orifice 21, allowing liquid to flow in from the end of the channel orifice 21 after passing through the neutral orifice 31. In another embodiment, the neutral orifice 31 is located at the center of the channel orifice 21, allowing liquid to flow in from the center of the channel orifice 21 after passing through the neutral orifice 31.

[0034] The shape and cross-sectional area of ​​the neutral hole 31 can be adjusted according to different experimental requirements. In one embodiment, the neutral hole 31 is a circular hole, and the diameter of the neutral hole 31 is the same as the width of the channel hole 21. When the neutral hole 31 is located at the end of the channel hole 21, the semi-circular structure at the end of the neutral hole 31 is opposite to that of the channel hole 21. In another embodiment, the neutral hole 31 is a circular hole, and the diameter of the neutral hole 31 is smaller than the width of the channel hole 21. In another embodiment, the neutral hole 31 is an oblong hole, and the long axis of the neutral hole 31 is arranged along the vertical direction. When the neutral hole 31 is located at the end of the channel hole 21, the semi-circular structure at the end of the neutral hole 31 is opposite to that of the semi-circular structure at the end of the channel hole 21.

[0035] Mounting assembly 4 includes positioning blocks 41 located on the mother disc 2. Multiple positioning blocks 41 are arranged opposite each other on both sides of the channel hole 21, and are symmetrically arranged along the center of the channel hole 21. This symmetrical arrangement of the positioning blocks 41 along the center point of the channel hole 21 reduces the need for operators to distinguish the direction of the adjusting piece 3. Furthermore, when the neutral hole 31 is located at the end of the adjusting piece 3, it reduces the possibility of the neutral hole 31 being located at both ends of the adjusting piece 3; the positioning hole only needs to be located at one end of the adjusting piece 3. A positioning groove 42 is horizontally formed on the surface of the positioning block 41 near the channel hole 21.

[0036] A locking block 43 is fixedly connected to the side wall of the adjusting plate 3 relative to the positioning block 41. The locking block 43 has the same shape as the positioning groove 42. The locking block 43 can extend into the interior of the positioning groove 42, thereby positioning and fixing the adjusting plate 3 and the mother disc 2.

[0037] The thickness of the locking block 43 is the same as the spacing between two adjacent female discs 2, and the thickness of other positions on the adjusting plate 3 is less than the thickness of the locking block 43. In one embodiment, the thickness of the locking block 43 is 1 mm, and the thickness of other positions on the adjusting plate 3 is 0.3 mm. This reduces the influence of the neutral hole 31 and the adjusting plate 3 on the fluid flow between the female discs 2.

[0038] Under the clamping force of the mother disc 2, the adjusting plate 3 is tightly attached to the upper mother disc 2, and only the neutral hole 31 is through which fluid flows, thus meeting the design requirements for feeding through the neutral hole 31.

[0039] During use, adjustment plates 3 with different parameters such as the diameter and distribution radius of the neutral hole 31 can be produced as needed, while the master disc 2 remains unchanged. After the master disc 2 is verified by experiments, the final position of the neutral hole 31 is determined, and the final version of the master disc 2 is produced and processed, thereby greatly improving the structural design efficiency of the master disc 2 in the process of new product development.
