Description

Technical Field

[0001] This utility model relates to the field of disc separator technology, and in particular to a disc for use in a disc separator. Background Technology

[0002] A disc centrifuge is a vertical centrifuge primarily used to separate difficult-to-separate materials, such as suspensions of viscous liquids and fine solid particles, or emulsions composed of liquids with similar densities. Its core component is a rotating drum mounted on a vertical shaft. Inside the drum are a set of stacked discs with very small gaps between them. When the suspension enters the drum through the feed pipe and flows through the gaps between the discs, the solid particles settle onto the discs under centrifugal force, forming sediment. The sediment slides along the disc surface and accumulates at the edge of the drum, while the separated clear liquid is discharged from the outlet. The existing technical solutions have the following shortcomings: The discs equipped in the current disc separators have a poor separation effect and are not conducive to the collection of clarified liquid. They also have significant deficiencies in structural strength. When these disc separators are in operation for a long time, the discs are more prone to wear and deformation due to insufficient strength. The continuous accumulation of these wear problems will not only directly lead to a significant reduction in the service life of the discs themselves, making it impossible for them to maintain stable working performance for a long time, but also gradually reduce the value of the discs in the separation work, making it difficult to meet the increasingly stringent separation process requirements. This will adversely affect the normal operation and efficiency of the entire disc separator equipment. At the same time, the discs equipped in the current disc separators are inconvenient to disassemble and clean. Utility Model Content The purpose of this invention is to overcome the defects in the existing technology and provide a design method for a disc guide channel and a disc for a disc separator.

[0003] To achieve the above objectives, the technical solution of this utility model is to design a disc guide channel for a disc separator. By digitally modeling the outer peripheral surface of the disc body, its geometric shape data is obtained, and feature extraction is performed in the generatrix direction to determine the layout scheme of the spaced guide channel. Based on the layout scheme of the guide channel, the structural parameters of the lower end connection and the upper end spacing are simulated using the finite element analysis method to obtain the preliminary distribution state of the emulsion flow in the disc gap. If the uniform distribution effect of the emulsion flow does not reach the preset threshold in the initial distribution state, the optimized structural data is regenerated by adjusting the interval distribution parameters of the guide channel. By performing fluid dynamics simulation on the optimized structural data, the dynamic distribution information of the emulsion flow in the disc gap is obtained, and it is determined whether a stable flow splitting structure is formed. If the dynamic distribution information shows that there is local unevenness in the diversion structure, then the structure is optimized for the local area of ​​the outer peripheral surface to obtain the adjusted diversion channel design scheme.

[0004] A further optimized technical solution involves digitally modeling the outer peripheral surface of the disc body to obtain several guide channels spaced apart along the generatrix direction. These channels are used to uniformly divide the emulsion entering the disc gap, thus obtaining a preliminary flow distribution structure.

[0005] A further preferred technical solution involves setting trumpet-shaped guiding arc surfaces at both ends of the guiding channel based on the preliminary diversion structure, guiding the flow path of the light liquid phase in the emulsion, and determining the optimal direction for the liquid to converge in the guiding channel.

[0006] A further optimized technical solution involves analyzing the initial diversion, digitally modeling the end of the guide channel, obtaining the geometric morphology data of the trumpet-shaped surface, and determining the initial arrangement scheme of the guide arc surface. Based on the initial layout plan, fluid dynamics simulation tools were used to analyze the distribution of the light liquid phase in the flow path and obtain preliminary data for path guidance. If the initial data for path guidance does not reach the preset threshold, the geometric parameters of the trumpet-shaped surface are adjusted, the arrangement scheme of the guiding arc surface is regenerated, and the optimized distribution information is obtained. By processing the optimized distribution information, it is determined whether the liquid collection method meets expectations and the direction of adjustment of the collection method is determined. Based on the adjustment direction of the collection method, local optimization is performed on the arrangement of the channel end to generate new design data for the guide channel end and obtain dynamic change information of liquid collection. A pre-established analytical model is used to process the dynamic changes in liquid collection, determine whether the diversion structure meets the design standards, and determine the final optimization direction. By implementing the final optimization direction, stable distribution data of the light liquid phase in the flow path is obtained, and the overall verification of the diversion structure is completed.

[0007] A disc for a disc separator, the disc comprising a disc body having a conical through hole inside the disc body and a plurality of guide grooves on the outer peripheral surface of the disc body.

[0008] In a further preferred embodiment, the guide channel is obtained by the design method of the disc guide channel for a disc separator.

[0009] In a further preferred embodiment, the disc body is provided with twelve guide grooves, which are evenly arranged.

[0010] A further preferred technical solution is that two parallel reinforcing ribs are provided on the disc body between two adjacent flow channels, and a reinforcing rib is provided on the line connecting the two ends of the upper reinforcing rib and the center of the lower reinforcing rib, forming multiple triangular areas on the disc body.

[0011] In a further preferred embodiment, the upper end of the disc body has an inner ring formed by an annular platform, the inner ring extends radially inward, and the inner side of the inner ring is provided with a set of discharge ports that extend axially through the inner ring.

[0012] In a further preferred embodiment, the inner side of the inner ring is provided with a set of positioning grooves, and each positioning groove is provided with a slidingly fitted positioning block. The cross-sectional shape of the positioning groove and the positioning block is V-shaped.

[0013] In a further preferred embodiment, each side of the positioning block is provided with a fastening screw hole, and the inner ring is thus threadedly connected to the fastening screw hole by a fastening bolt.

[0014] The advantages and beneficial effects of this utility model are as follows: An initial digital model is constructed using high-precision laser scanning. Parametric modeling and curvature analysis are then used to generate a flow guide channel. Fluid dynamics simulation software is employed to model the turbulent path and velocity gradient distribution, optimizing the radius of curvature to improve flow uniformity. Simultaneously, finite element analysis is used to evaluate stress distribution and deformation resistance. Flow guide channel parameters and reinforcing rib layout are iteratively adjusted to ensure the design meets dual requirements. Finally, design parameters and fluid behavior data are integrated to generate a complete solution, which is then validated through classification to ensure uniform distribution and structural stability. This invention significantly improves separation efficiency and equipment durability, providing reliable technical support for complex fluid separation scenarios.

[0015] Because of the flow guide channels, when the emulsion enters the gap between the disc bodies, the flow guide channels can evenly divide the flowing emulsion. Through this diversion effect, the impact force generated by the emulsion on the disc body surface under high-speed flow can be significantly reduced. This design can not only reduce the probability of wear and fatigue cracks caused by long-term impact on the disc body, but also fundamentally extend the actual service life of the disc body, further enhancing its value in industrial production or separation processes, and ensuring that the separation equipment maintains stable and reliable working performance during long-term operation. At the same time, by fixing reinforcing ribs between the flow guide channels, the shape of which is triangular, due to the unique geometric stability of the triangle itself, this structural characteristic can effectively enhance the overall structural strength of the separator disc body, making it less prone to deformation or damage when subjected to external loads or high-speed operation.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] A design method for disc guide channels in a disc separator involves digitally modeling the outer peripheral surface of the disc body to obtain its geometric morphology data, extracting features along the generatrix direction, and determining a layout scheme for the spaced guide channels. Based on the layout scheme of the guide channel, the structural parameters of the lower end connection and the upper end spacing are simulated using the finite element analysis method to obtain the preliminary distribution state of the emulsion flow in the disc gap. If the uniform distribution effect of the emulsion flow does not reach the preset threshold in the initial distribution state, the optimized structural data is regenerated by adjusting the interval distribution parameters of the guide channel. By performing fluid dynamics simulation on the optimized structural data, the dynamic distribution information of the emulsion flow in the disc gap is obtained, and it is determined whether a stable flow splitting structure is formed. If the dynamic distribution information shows that there is local unevenness in the diversion structure, then the structure is optimized for the local area of ​​the outer peripheral surface to obtain the adjusted diversion channel design scheme.

[0020] When digitally modeling the outer peripheral surface of the disc body, geometric data can be obtained through high-precision 3D scanning technology. Assuming the disc diameter is 200 mm and the thickness is 2 mm, the scanning accuracy reaches 0.01 mm, ensuring that the minute undulations and feature points of the outer peripheral surface are captured. After modeling, feature extraction in the generatrix direction can identify areas on the outer peripheral surface suitable for arranging flow channels. For example, within a 5 mm range near the edge, 10 evenly distributed key points can be extracted as the starting point of the channel. This method helps to accurately locate the layout of the flow channels and improve the uniformity of subsequent fluid distribution.

[0021] In one possible implementation, the finite element analysis of the flow channel layout can be performed using a fluid-structure coupled simulation tool to simulate the distribution of the emulsion flow within the disc gaps. Assuming the width of the lower connected region is 3 mm and the upper spacing is 1.5 mm, the simulation results show that the flow rate of the emulsion near the lower end reaches 60%, while the flow rate in the middle and upper regions is insufficient. If this uneven distribution does not reach a preset threshold, such as uniformity less than 85%, the spacing parameters of the flow channels need to be adjusted. For example, the channel spacing can be adjusted from a uniform 5 mm to a gradual 3 to 7 mm to optimize the fluid distribution effect.

[0022] When performing fluid dynamics simulations on the optimized structural data, the dynamic distribution information of the emulsion flow can be further analyzed. Suppose the simulation shows that the velocity distribution of the fluid in the gap between the discs fluctuates greatly, with the flow velocity in some areas reaching as high as 0.5 m / s, while in other areas it is only 0.2 m / s, indicating that the flow splitting structure is unstable. In this case, for the local area optimization of the outer surface, micro-guide protrusions with a height of 0.3 mm and a width of 1 mm can be added in areas with excessively high flow velocities to reduce local flow velocities and improve overall uniformity.

[0023] After performing fluid dynamics simulation again on the adjusted guide channel design, the final emulsion flow distribution data can be obtained. Assuming that the final simulation shows that the fluid uniformity reaches 90% and there is no obvious local accumulation phenomenon, it can be determined that the flow splitting structure meets the design requirements. This optimized design can significantly reduce the energy loss of the emulsion flow during the separation process and improve the separation efficiency.

[0024] For the analysis and verification of the final distribution data, virtual flow field visualization technology can be used to observe the fluid distribution within the disc gaps. If a slight flow deviation is found near the edge, the optimal structural parameters of the outer surface can be further fine-tuned, such as adjusting the depth of the guide channel from 1 mm to 1.2 mm, to ensure that the fluid distribution reaches its optimal state. This method not only improves the scientific rigor of the design but also effectively extends the disc's lifespan and reduces maintenance costs.

[0025] A further optimized technical solution involves digitally modeling the outer peripheral surface of the disc body to obtain several guide channels spaced apart along the generatrix direction. These channels are used to uniformly divide the emulsion entering the disc gap, thus obtaining a preliminary flow distribution structure.

[0026] A further preferred technical solution involves setting trumpet-shaped guiding arc surfaces at both ends of the guiding channel based on the preliminary diversion structure, guiding the flow path of the light liquid phase in the emulsion, and determining the optimal direction for the liquid to converge in the guiding channel.

[0027] A further optimized technical solution involves analyzing the initial diversion, digitally modeling the end of the guide channel, obtaining the geometric morphology data of the trumpet-shaped surface, and determining the initial arrangement scheme of the guide arc surface. Based on the initial layout plan, fluid dynamics simulation tools were used to analyze the distribution of the light liquid phase in the flow path and obtain preliminary data for path guidance. If the initial data for path guidance does not reach the preset threshold, the geometric parameters of the trumpet-shaped surface are adjusted, the arrangement scheme of the guiding arc surface is regenerated, and the optimized distribution information is obtained. By processing the optimized distribution information, it is determined whether the liquid collection method meets expectations and the direction of adjustment of the collection method is determined. Based on the adjustment direction of the collection method, local optimization is performed on the arrangement of the channel end to generate new design data for the guide channel end and obtain dynamic change information of liquid collection. A pre-established analytical model is used to process the dynamic changes in liquid collection, determine whether the diversion structure meets the design standards, and determine the final optimization direction. By implementing the final optimization direction, stable distribution data of the light liquid phase in the flow path is obtained, and the overall verification of the diversion structure is completed.

[0028] Specifically, when digitally modeling the end of the guide channel, one can start by understanding the geometric data of the trumpet-shaped surface to grasp its design principle. The trumpet-shaped surface is usually designed to guide the fluid through a smooth transition and reduce flow resistance. Its geometry directly affects the distribution of the fluid. Assuming that the geometric data of the channel end is obtained through a high-precision scanning device, and the opening angle of the trumpet-shaped surface is set to 30 degrees, the bottom width is 4 mm, and the top width is extended to 8 mm, this design can initially guide the fluid to diffuse from a narrow area to a wide area, forming a relatively gentle flow path.

[0029] For the fluid dynamics simulation analysis of the initial layout scheme, professional software can be used to simulate the distribution of light liquid phase in the flow path. Assuming that the fluid inlet velocity is set to 0.2 m / s and the path length is 50 mm in the simulation, it is observed that the fluid distribution in the funnel-shaped area shows a certain bias, with the flow rate on the side closer to the other side accounting for 70%. If the preset threshold is uniformity of 80%, the geometric parameters need to be adjusted, such as adjusting the opening angle from 30 degrees to 35 degrees, and regenerating the layout scheme of the guide arc surface in order to improve the distribution state.

[0030] In the optimized distribution information processing, when judging whether the liquid collection method meets expectations, we can pay attention to the dynamic characteristics of the fluid when it collects at the end of the tank. Assuming that the uniformity of fluid distribution in the collection area is improved to 82% after optimization, but there are still local cases of excessively fast collection, it can be inferred that the radius of curvature of the collection path needs to be further adjusted, for example, from 10 mm to 12 mm, to slow down the fluid collection speed and achieve a smoother transition effect.

[0031] For local optimization of the channel end arrangement, one can start with the edge surface design of the guide channel end. For example, adding a 2mm radius arc transition surface to the edge region reduces the impact force of the fluid during convergence. Simultaneously, placing small guide protrusions near the convergence point, with a height of 0.5mm and a width of 1mm, further disperses the fluid pressure. This design helps improve fluid stability.

[0032] When analyzing the dynamic changes in liquid collection, a pre-established analytical model can be used to observe the changes in the collection velocity of the fluid over different time periods. If the model shows that the collection velocity of the fluid fluctuates greatly in the first 5 seconds, reaching a maximum of 0.3 m / s, and then tends to stabilize, it can be determined that the diversion structure still has room for improvement in dynamic adaptability. The geometric details of the guide channel end need to be further optimized, such as deepening the depth of the channel end to 1.5 mm.

[0033] To implement the final optimization direction, multiple iterative simulations can be used to obtain stable distribution data of the light liquid phase in the flow path. Assuming that the final simulation shows that the fluid distribution uniformity reaches 88% and there is no significant fluctuation in the collection area, the diversion structure design can be considered to basically meet the standard. This design method can effectively improve the accuracy of fluid guidance and provide reliable support for subsequent processes.

[0034] During the overall verification process, virtual visualization tools can be used to visually present the flow trajectory of fluid in the diversion structure. If the visualization results show that the fluid path is smooth and there is no obvious flow deviation, the rationality of the design is further verified. This method helps to discover potential problems and make timely adjustments to ensure that the design achieves the expected goals.

[0035] Reference Figure 1-4As shown, a disc is used in a disc separator. The disc is a key component of the disc separator and is mostly conical in structure. The disc separator contains several discs, which are stacked in the direction of finished product flow to form multiple channels in the direction of finished product flow. The material is separated in the space between two adjacent discs. The emulsion enters the gap between the disc bodies 3 of the separator. At this time, the heavy liquid phase in the emulsion settles under centrifugal force and flows along the disc body 3 of the separator to one side and gradually accumulates. The light liquid phase in the emulsion flows upward along the surface of the disc body 3 of the separator and is finally discharged from the discharge pipe under the action of a centrifugal pump. The disc includes a disc body 3, which has a conical through hole 7 inside. The disc body 3 is made by punching a large-size steel plate into a circular blank suitable for spinning, and then processing the blank into the shape of a disc by rollers. Then, the mechanical properties of the disc are improved by heat treatment.

[0036] Several guide grooves 4 are spaced along the generatrix of the disc body 3 on its outer peripheral surface. These guide grooves allow the light liquid phase in the flowing emulsion to flow upwards along the surface of the separator disc body 3, and finally be discharged from the discharge pipe under the action of a centrifugal pump. This also achieves a uniform division of the emulsion. Through this diversion effect, the impact force generated by the emulsion on the surface of the disc body 3 under high-speed flow can be significantly reduced. Specifically, the guide grooves are recessed on the outer peripheral surface of the disc body 3, and the guide grooves 4 form protruding ribs on the inner side of the disc body 3, which can strengthen the disc body 3. One end of the guide groove 4 is located on the lower end face of the disc body 3 and is continuous, while the other end of the guide groove 4 is close to the upper end face of the disc body 3 and maintains a certain distance. Both ends of the guide groove 4 have trumpet-shaped guiding arc surfaces, which helps the light liquid phase to converge into the guide groove 4.

[0037] In one embodiment, the disc body 3 is provided with twelve guide channels 4, which are evenly arranged. Most of the light liquid phase in the emulsion is collected along the guide channels 4 on the surface of the separator disc body 3, and then discharged from the discharge pipe by the guide channels 4 under the action of the centrifugal pump. The twelve guide channels 4 divide the outer peripheral surface of the disc body 3 into multiple uniform fan-shaped areas, which has the effect of uniformly dividing the emulsion. Through this diversion effect, the impact force generated by the emulsion on the surface of the disc body 3 under high-speed flow can be significantly reduced. This design can not only reduce the probability of wear, fatigue cracks and other problems caused by long-term impact on the disc body 3, but also fundamentally extend the actual service life of the disc body 3, further enhance its use value in industrial production or separation process, and ensure that the separation equipment maintains stable and reliable working performance during long-term operation.

[0038] A through hole 5 is provided on the disc body 3 between the two guide channels 4. The through hole 5 penetrates the disc body 3. The through hole 5 can be used to communicate the distribution of emulsion and light liquid phase between two adjacent discs. It can evenly distribute emulsion and light liquid phase between the discs, thereby improving separation efficiency and separation quality.

[0039] The through hole 5 is located near the lower end face of the disc body 3, which helps to distribute the emulsion and light liquid phase in the initial stage of separation. In some embodiments, the through hole 5 is a circular hole, which is convenient for processing on the disc body 3 and can reduce the production cost.

[0040] In some embodiments, when the number of the flow guide grooves 4 is twelve, the number of the through holes 5 is twelve, that is, a through hole 5 is provided between two adjacent flow guide grooves 4. Of course, in some embodiments, the number of the through holes 5 is six, that is, the through holes 5 are arranged between the flow guide grooves 4 in an intermittent manner on the disc body 3.

[0041] A set of reinforcing ribs 6 are provided on the disc body 3 between two adjacent guide channels 4. The reinforcing ribs 6 protrude from the disc body 3. By using the reinforcing ribs 6, the strength of the separator disc body 3 can be enhanced, and its service life and value can be extended. Specifically, two parallel reinforcing ribs 6 are provided on the disc body 3 between two adjacent guide channels 4. A reinforcing rib 6 is provided on the line connecting the two ends of the upper reinforcing rib 6 and the center of the lower reinforcing rib 6, forming multiple triangular areas on the disc body 3. The triangular reinforcing ribs 6 can significantly improve the strength of the disc body 3. By using the reinforcing ribs 6, the strength of the separator disc body 3 can be enhanced, and its service life and value can be extended.

[0042] In one embodiment, six sets of reinforcing ribs 6 are evenly provided on the disc body 3. The six sets of reinforcing ribs 6 can not only strengthen the disc body 3, but also leave an area on the disc body 3 for the convergence of the emulsion and light liquid phase guide channel 4.

[0043] The upper end of the disc body 3 has an inner ring 1 formed by an annular platform. The inner ring 1 extends radially inward. The inner side of the inner ring 1 is provided with a set of discharge ports 2 that are axially connected through the inner ring. The set of discharge ports 2 are evenly distributed around the axis. The light liquid phase in the emulsion flows upward along the surface of the separator disc body 3 and is finally discharged from the discharge ports 2 under the action of the centripetal pump. In one embodiment, the inner ring 1 is provided with eight discharge ports 2, and the shape of the discharge ports 2 is trapezoidal. To facilitate positioning when a set of discs is stacked, a set of positioning grooves 8 are provided on the inner side of the inner ring 1. The positioning grooves 8 are located between two adjacent discharge ports 2 and are evenly distributed on the inner side of the inner ring 1. When a set of discs is stacked together, the positioning grooves 8 of different discs are aligned, and the positioning blocks 9 arranged axially are inserted into the positioning grooves 8 to position the set of discs in a specified direction. The positioning grooves 8 and the positioning blocks 9 are slidably connected, and the positioning blocks 9 can be fixed on the disc rack 12 of the separator.

[0044] By utilizing the interlocking connection between the positioning groove 8 and the positioning block 9, the installation between the separator disc body 3 and the main shaft can be initially positioned to prevent misalignment during installation. Each side of the positioning block 9 is provided with a fastening screw hole 10, and the inner ring 1 is threadedly connected to the fastening screw hole 10 by a fastening bolt 11.

[0045] like Figure 4 As shown, by using the fastening screw hole 10, an additional locking force is applied to the connection relationship, thereby improving the stability of the connection structure through the locking effect; In one embodiment, the cross-sectional shape of the positioning groove 8 and the positioning block 9 is V-shaped. This shape can not only serve as a solid positioning structure, but also increase the contact area of ​​the continuous load, allowing the positioning structure to withstand a large centrifugal force, enabling the disc to achieve a stable working state and have a long service life. The interlocking relationship between the positioning groove 8 and the positioning block 9 plays a preliminary positioning role in the installation of the disc body 3 of the separator. After the preliminary positioning is completed, the fastening bolts 11 are used to apply additional locking force to the connection between the two, thereby further fixing the assembly relationship.

[0046] After the emulsion enters the drum of the separator, it begins to separate during the drum's rotation. During separation, the emulsion enters the gap between the separator discs 3. At this time, the heavy liquid phase in the emulsion settles under centrifugal force and flows along the separator discs 3 to one side of the drum, gradually accumulating. Meanwhile, the light liquid phase in the emulsion flows upward along the surface of the separator discs 3, gradually rising through the discharge port 2 on the inner ring 1, and finally being discharged from the discharge port 2 under the action of the centrifugal pump. Because of the flow guide 4, when the emulsion enters the gap between the disc bodies 3, the flow guide 4 can evenly divide the flowing emulsion. Through this diversion effect, the impact force generated by the emulsion on the surface of the disc body 3 under high-speed flow can be significantly reduced. This design can not only reduce the probability of wear and fatigue cracks caused by long-term impact on the disc body, but also fundamentally extend the actual service life of the disc body 3, further enhance its use value in industrial production or separation process, and ensure that the separation equipment maintains stable and reliable working performance during long-term operation. At the same time, by fixing reinforcing ribs 6 between the flow guide 4, the shape of which is triangular, due to the unique geometric stability of the triangle itself, this structural characteristic can effectively enhance the overall structural strength of the separator disc body 3, making it less prone to deformation or damage when subjected to external loads or high-speed operation. By using the interlocking connection formed by the positioning block 9 and the positioning groove 8, the installation position between the separator disc body 3 and the disc holder can be positioned. This interlocking connection can quickly define the relative position of the separator disc body 3 in the early stage of installation, preventing it from shifting or shaking on the disc holder. This provides a basic position reference for subsequent precise installation. After the initial positioning is completed, additional locking force is applied to the connection between the two using fastening bolts, thereby further fixing the assembly relationship and ensuring that the entire connection structure remains stable and reliable during equipment operation, while also facilitating its disassembly and maintenance.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
