Description

Technical Field

[0001] This utility model relates to the field of support grid technology, specifically a PTFE composite support grid. Background Technology

[0002] PTFE composite support grid is a composite structural component that combines polytetrafluoroethylene (PTFE) and metal materials. It typically consists of a metal inner lining as a support frame and an outer layer covered with PTFE material, combining the high strength of metal with the corrosion resistance and high temperature resistance of PTFE. This type of support grid is widely used in chemical equipment, such as in steam scrubbing towers. It can enhance the strength of the packing support structure, reduce the thickness of the support orifice plate, and is resistant to high and low temperature changes and corrosion. In addition, it has good thermal stability, and its performance in complex environments can be further improved by optimizing the material combination and manufacturing process. PTFE composite support grid is a composite structure made up of PTFE strips of different lengths. During installation, in order to accurately control the spacing between the PTFE strips, the existing technology usually uses sleeves for spacing. However, this method requires a large number of sleeves to complete the installation, which not only increases the complexity of the installation, but also leads to a significant increase in installation time and cost. Therefore, a PTFE composite support grid is proposed to address the above problems. Utility Model Content

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A PTFE composite support grid includes PTFE strips 1, with a support assembly 2 and an auxiliary plug 3 inserted into the inner side of the PTFE strips 1. The support assembly 2 and the auxiliary plug 3 are fixed together by bolts 4. The support assembly 2 includes a post 21, with guide grooves 22 at both the front and rear ends of the post 21. Positioning plates 24 are fixedly connected to the upper and lower ends of the post 21. A positioning groove 23 is provided between the post 21 and the positioning plate 24. A fixing hole 25 is provided inside the post 21 near the guide groove 22. The auxiliary plug 3 includes an arc-shaped plate 31, with an extension strip 32 fixedly connected to the arc-shaped plate 31 near the post 21. An anti-torsion plate 34 is provided at the end of the arc-shaped plate 31 away from the extension strip 32. A pressure hole 33 is provided inside the arc-shaped plate 31.

[0017] As a further implementation of this solution, the PTFE strip 1 includes a PTFE strip body 11. The inner side of the PTFE strip body 11 has a round hole 12 and a square hole 13, which are connected. The insert post 21 is inserted into the inside of the round hole 12, and the positioning groove 23 is aligned vertically with the round hole 12. Through the above arrangement, by opening the connected round hole 12 and square hole 13 on the inner side of the PTFE strip body 11, a unique structural layout is formed, which provides a basis for subsequent cooperation with other components. The insert post 21 is inserted into the inside of the PTFE strip body 11, which enables the entire device to achieve the integration of positioning and support functions, reduces the complexity of positioning that requires additional components in traditional installation, improves the compactness and integrity of the structure, and lays the foundation for subsequent rapid installation and efficient operation. As a further implementation of this solution, guide grooves 22 are provided at both the front and rear ends of the insertion post 21, and the fixing holes 25 are connected to the guide grooves 22 at both the front and rear ends. With the above settings, the arc plate 31 and the insertion post 21 can be fixed by bolts 4. As a further implementation of this solution, a gap is provided between the two positioning plates 24. The two positioning plates 24 are clamped to the outside of the PTFE strip body 11 through the gap. Through the above arrangement, the PTFE strip body 11 is stably supported and positioned, effectively preventing the PTFE strip body 11 from loosening or falling off during operation, greatly improving the stability and reliability of the device, and ensuring the efficient operation and long-term stability of the entire structure under complex working conditions. As a further implementation of this solution, the end of the arc plate 31 near the extension strip 32 is attached to the outside of the insert post 21. The extension strip 32 is embedded in the guide groove 22. The outside of the anti-torsion plate 34 is attached to the inside of the square hole 13. The pressing hole 33 is aligned with the fixing hole 25. The two arc plates 31 are fixed to the insert post 21 by bolts 4. With the above arrangement, the extension strip 32 is embedded in the guide groove 22, which further enhances the stability of the connection and prevents the components from loosening or falling off during operation. The attachment of the anti-torsion plate 34 to the square hole 13 provides additional support and positioning for the device, making the entire device more stable and reliable during installation and operation. It can prevent the insert post 21 and the arc plate 31 from twisting inside the PTFE strip body 11.

[0018] Workflow: During installation, first rotate the insert post 21 90 degrees so that the positioning plate 24 faces the front-back direction. Then, align the round holes 12 and square holes 13 on the PTFE strip body 11 with the insert post 21 and the positioning plate 24, respectively. Slide the PTFE strip body 11 outside the insert post 21. When the designated round hole 12 on the PTFE strip body 11 aligns with the positioning groove 23, ensure that the round hole 12 on the PTFE strip body 11 fits against the outer side of the positioning groove 23. This achieves the positioning effect between the PTFE strip body 11 and the insert post 21. The positioning groove 23 extends to the gap between the positioning plate 24, preventing gaps from forming between the insert post 21 and the PTFE strip body 11 after the insert post 21 is rotated. Install multiple PTFE strip bodies 11 in this manner. After all multiple PTFE strip bodies 11 are fitted onto the outside of the insert post 21 and aligned, rotate the insert post 21 90 degrees. At this point, the two positioning... All plates 24 are positioned vertically. The spacing between the two positioning plates 24 is adjusted to clamp the PTFE strip body 11. After inserting the other support components 2 into the round holes 12 and square holes 13 respectively, and then rotating them for installation, after the multiple support components 2 are installed, the extension strip 32 fixed by the arc plate 31 is inserted into the guide groove 22, and the arc plate 31 is inserted into the square hole 13. When the multiple anti-torsion plates 34 are respectively located in the corresponding square holes 13, until the pressure hole 33 is aligned with the fixing hole 25, the support components 2 and auxiliary plug-in 3 are fixed by bolts 4. The remaining auxiliary plug-in 3 are installed in the same way to complete the assembly. Based on the above principles, the device changes the traditional method of positioning the sleeve one by one during installation. The positioning structure and the support structure are integrated into one, which improves the convenience of installation, reduces the installation cost, and ensures the strength of the support for multiple PTFE strip bodies 11.
