Description

Technical Field

[0001] This utility model belongs to the technical field of chemical production equipment and organosilicon refining, specifically a high-efficiency packing support structure for organosilicon distillation towers. Background Technology

[0002] In the production and processing of organosilicon materials, distillation is a core process for achieving product purification and ensuring product quality. The packing support structure within the distillation column, as a critical load-bearing component, directly affects the uniformity of packing distribution, gas-liquid contact efficiency, and the long-term stable operation of the distillation system. During organosilicon distillation, the column must withstand the long-term effects of high temperature, high pressure, and corrosive media. Simultaneously, the support structure must possess sufficient mechanical strength to support the weight of the packing and ensure smooth gas-liquid flow, preventing channeling, flooding, and other phenomena, thereby guaranteeing distillation separation efficiency.

[0003] Meanwhile, a high-efficiency distillation extraction device for organosilicon coupling agents is disclosed (announcement number CN216725845U), including a device body, the device body including a distillation column, a mounting frame fixed at the upper end of the distillation column, a slide rail slidably provided on the surface of the mounting frame, two stops fixed on both sides of the mounting frame, a return spring connected to both sides of the slide rail and the two stops, and a packing frame rotatably provided on the slide rail.

[0004] In the aforementioned high-efficiency distillation extraction device for organosilicon coupling agents, the sliding and oscillating function of the packing frame is achieved through a combination of a return spring, a support spring, a slide, and a sliding plate. However, the springs are constantly under fatigue from repeated extension and contraction, and under the temperature changes and vibrations during the operation of the distillation column, they are prone to elastic decay or breakage, leading to uncontrolled swaying of the packing frame and affecting the uniformity of packing placement. Furthermore, the device assists in the oscillation of the packing frame through the contact between the support wheel frame and the sliding plate, and the wear between the wheel frame and the sliding plate will exacerbate the risk of equipment failure.

[0005] Therefore, a high-efficiency packing support structure for organosilicon distillation columns is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a high-efficiency packing support structure for organosilicon distillation columns, which has the advantages of good adaptability and durability, strong support stability, and efficient assembly and disassembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency packing support structure for an organosilicon distillation column, comprising a fixed column, a central column fixedly disposed at the middle of the lower end face of the fixed column, an arc-shaped plate fixedly disposed at the lower end face of the fixed column, a positioning plate fixedly disposed on the outside of the arc-shaped plate, a connecting plate fixedly disposed at the lower end face of the fixed column, a buckle fixedly disposed on the outside of the connecting plate, and a limiting plate fixedly disposed on the outside of the connecting plate. The arc-shaped plate can increase the strength and load-bearing capacity of the structure and may help guide the flow of fluid.

[0008] Preferably, the buckle is externally fixed with a fixing tube, and the fixing tube has a positioning groove inside, which is slidably disposed with the positioning plate.

[0009] By adopting the above technical solution, the positioning plate can slide within the positioning groove through the fixed pipe positioning groove, playing a role in precise guidance and positioning during the installation process, thus ensuring the accuracy of the connection between components.

[0010] Preferably, the fixing tube has a bayonet opening inside, and the buckle is fitted with the bayonet opening. The upper end face of the fixing column is fixed with a connecting tube, and the connecting tube has a threaded hole inside.

[0011] By adopting the above technical solution, the tightness of the connection between components is further enhanced through the use of bayonets and buckles, which can effectively prevent the components from loosening and shifting during use, and improve the overall stability of the support structure.

[0012] Preferably, a fixing ring is fixedly provided on the left end face of the fixing tube, and a square groove is provided inside the fixing ring.

[0013] By adopting the above technical solution, the square groove provides operators with a convenient operating space. For example, the square groove can be used to install, debug, and maintain the components inside the fixing ring, thus improving the convenience of operation.

[0014] Preferably, a threaded rod is fixedly provided inside the fixing ring, and the threaded rod is spirally arranged with the threaded hole; a fine-mesh screen is fixedly provided inside the fixing ring.

[0015] By adopting the above technical solution, the threaded rod and threaded hole can effectively prevent the components from loosening under vibration or fluid impact, thus ensuring the stability and reliability of the connection between the support structure and other components.

[0016] Preferably, a support ring one is fixedly provided on the upper end face of the connecting pipe, and a support ring two is fixedly provided on the upper end face of the support ring one.

[0018] Preferably, a fixing rod is fixedly provided inside the second support ring, and a coarse-mesh screen is fixedly provided inside the second support ring.

[0019] By adopting the above technical solution, some larger particles can be blocked through the coarse-mesh screen, while allowing the fluid to pass through evenly, ensuring the uniform distribution of the fluid in the distillation column and improving distillation efficiency and quality.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the use of arc-shaped plates, can reduce eddies and stagnant flow phenomena during fluid flow, and avoid the formation of dead zones by liquid staying on the surface of the support structure. This can prevent organosilicon materials from undergoing local polymerization due to prolonged residence, ensuring product purity, and also reduce energy loss during fluid flow. It can also reduce the occupation of cross-sectional area inside the tower, reserve more space for gas-liquid flow, reduce pressure drop, and avoid problems such as flooding at the support that affect distillation efficiency.

[0021] 2. This utility model, through the second support ring and the fixing rod, can distribute the weight of the filler to various parts of the second support ring, avoiding uneven stress on the support ring due to the middle area being suspended. At the same time, it can also enhance the deformation resistance of the support ring itself, ensure the flatness of the support ring for long-term use, and provide a stable support foundation for the filler layer.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following describes an embodiment of this utility model based on its overall structure.

[0026] like Figures 1 to 5 As shown, this utility model provides a high-efficiency packing support structure for an organosilicon distillation column, including a fixed column 10, a central column 16 fixedly disposed at the middle of the lower end face of the fixed column 10, an arc-shaped plate 12 fixedly disposed at the lower end face of the fixed column 10, a positioning plate 11 fixedly disposed on the outside of the arc-shaped plate 12, a connecting plate 13 fixedly disposed at the lower end face of the fixed column 10, a buckle 15 fixedly disposed on the outside of the connecting plate 13, and a limiting plate 14 fixedly disposed on the outside of the connecting plate 13. Through the arc-shaped plate 12, eddies and stagnant flow phenomena during fluid flow can be reduced, and liquid can be prevented from staying on the surface of the support structure to form dead zones. This can prevent organosilicon materials from undergoing local polymerization due to prolonged residence, ensuring product purity, reducing energy loss of fluid flow, reducing the occupation of cross-sectional area inside the column, reserving more space for gas-liquid flow, reducing pressure drop, and avoiding problems such as flooding at the support that affect distillation efficiency.

[0027] In this embodiment, the buckle 15 is further fixed with a fixing tube 20 on the outside. The fixing tube 20 has a positioning groove 18 inside, and the positioning groove 18 is slidably disposed with the positioning plate 11. Through the fixing tube 20 and the positioning groove 18, the positioning plate 11 can slide in the positioning groove 18, which plays a role in precise guidance and positioning during the installation process, ensuring the accuracy of the connection between the components.

[0028] The fixed tube 20 has a bayonet 19 inside, and the buckle 15 is fitted with the bayonet 19. The upper end face of the fixed column 10 is fixed with a connecting tube 5, and the connecting tube 5 has a threaded hole 9 inside. Through the bayonet 19 and the buckle 15, the tightness of the connection between the components is further enhanced, which can effectively prevent the components from loosening and shifting during use, and improve the overall stability of the support structure.

[0029] A fixing ring 6 is fixedly provided on the left end face of the fixing tube 20. A square groove 17 is provided inside the fixing ring 6. The square groove 17 provides an easy space for the operator to operate. For example, the components inside the fixing ring 6 can be installed, adjusted and maintained through the square groove 17, which improves the convenience of operation.

[0030] The fixed ring 6 is internally provided with a threaded rod 8, and the threaded rod 8 and the threaded hole 9 are spirally arranged. The fixed ring 6 is internally provided with a fine mesh screen 7. Through the threaded rod 8 and the threaded hole 9, the components can be effectively prevented from loosening under vibration or fluid impact, thus ensuring the stability and reliability of the connection between the support structure and other components.

[0031] A support ring 1 is fixedly provided on the upper end face of the connecting pipe 5, and a support ring 2 is fixedly provided on the upper end face of the support ring 1. The weight of the packing can be distributed through the support rings, reducing the pressure on the connecting pipe 5, thereby improving the support capacity of the entire support structure for the packing and ensuring the stable placement of the packing in the distillation column.

[0032] The support ring 2 is fixedly equipped with a fixing rod 4 and a coarse-mesh screen 3. The coarse-mesh screen 3 can block some larger particles while allowing the fluid to pass through evenly, thus ensuring the uniform distribution of the fluid in the distillation column and improving the distillation efficiency and quality.

[0033] Working principle and process of a high-efficiency packing support structure for an organosilicon distillation column: First, the fixing column 10 is placed in a suitable position inside the distillation column. The central column 16 in the middle of the lower end face of the fixing column 10 plays a preliminary positioning role, providing stable central support for the entire support structure. The arc plate 12 and its external positioning plate 11, connecting plate 13 and its external buckle 15 and limiting plate 14 are also in place. The fixing tube 20 is installed on the outside of the buckle 15. Since the fixing tube 20 has a positioning groove 18 inside, the positioning plate 11 can slide in the positioning groove 18 to achieve preliminary connection and positioning. At the same time, the buckle 15 is fitted with the bayonet 19 inside the fixing tube 20, which further enhances the connection stability between the fixing column 10 and the fixing tube 20. On the upper end face of the fixing column 10, the connecting tube 5 plays an important role. The connecting tube 5 has a threaded hole 9 inside, and the threaded rod 8 inside the fixing ring 6 is spirally arranged with the threaded hole 9. By rotating... The fixing ring 6 can be tightly connected to the connecting pipe 5. The fine-mesh screen 7 inside the fixing ring 6 can perform preliminary filtration of the material to remove impurities. The upper end face of the connecting pipe 5 is sequentially equipped with support ring 1 and support ring 2. The fixing rod 4 inside the support ring 2 enhances the stability of the structure. The coarse-mesh screen 3 can further filter and disperse the material, making the material more evenly distributed in the packing layer. When the distillation column is running, the material enters from the top, first passes through the coarse-mesh screen 3 in the support ring 2 for preliminary dispersion and filtration, and then enters the space below the fixing column 10 through the connecting pipe 5. The fine-mesh screen 7 in the fixing pipe 20 performs fine filtration of the material again to ensure the purity of the material entering the packing layer. At the same time, the various components of this support structure are closely matched to provide stable support for the packing and ensure the efficient operation of the distillation process.
