Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically to a high-temperature filter media support structure. Background Technology

[0002] In the field of filtration technology, filtration operations in high-temperature environments are particularly complex and challenging. Traditional high-temperature filter media often rely on external support devices to maintain their shape and filtration efficiency. However, most existing support structures are simply designed, directly inserting the support components inside the filter bag. While this design provides some support, it presents numerous problems in practice. For example, the filter bag is prone to detaching from the support components due to airflow impact or material friction, leading to decreased filtration efficiency or even filter bag damage. Furthermore, the direct contact between the support components and the inside of the filter bag can cause contamination from burrs, stains, and other debris on the component surface, affecting filtration quality. Therefore, developing a stable, reliable, and contamination-free high-temperature filter media support structure is crucial. Utility Model Content

[0003] The purpose of this invention is to provide a high-temperature filter material support structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes an external fixing component, the inner wall of which has an internal cavity, and the inner wall of which is provided with an internal support component. The external fixing component includes an external fixing ring, the outer wall of which is fixedly connected to a bottom connecting ring, and the bottom of which is fixedly connected to an external support filter. The internal cavity is located inside the external support filter. The internal support component includes an internal fixing ring, the outer wall of which is fixedly connected to a top connecting ring, and the bottom of which is uniformly fixedly connected to multiple support columns. The bottoms of the multiple support columns are jointly fixedly connected to a base plate.

[0005] As a further embodiment of this utility model: the outer diameter of the top connecting ring matches the outer diameter of the bottom connecting ring, and the outer diameter of the base plate is smaller than the inner diameter of the internal cavity.

[0006] As a further improvement of this utility model: the top outer walls of the multiple support columns are jointly fixedly connected with multiple reinforcing rings, and the top connecting rings are evenly provided with multiple through threaded holes.

[0007] As a further embodiment of this utility model: the bottom connecting ring and the top of the multiple through threaded holes are all fixedly connected with connecting bolts, and the multiple connecting bolts are movably connected through the through threaded holes that match the positions.

[0008] As a further improvement of this utility model, each of the multiple connecting bolts having a locking nut threadedly connected to one end of the threaded hole is a connecting bolt.

[0009] As a further improvement of this utility model, the distance between the top and bottom of the plurality of support columns is less than the height distance between the top and bottom of the internal cavity.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: The separate design of the inner support component and the outer fixing component makes the installation and replacement of the filter bag more convenient and quick, improving work efficiency. Secondly, the use of connecting bolts and locking nuts ensures a stable connection between the inner support component and the outer fixing component, effectively preventing the filter bag from detaching during use. Simultaneously, the external support filter screen not only enhances the overall structural stability but also provides isolation and protection for the outer wall of the filter bag, preventing direct contact and contamination from external pollutants. Furthermore, the design of this support structure considers the expansion and contraction space of the filter bag, ensuring stable filtration performance under different operating conditions. In summary, the high-temperature filter media support structure of this utility model exhibits excellent performance in terms of filtration efficiency, stability, and service life.

They 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. Therefore, they should not be construed as limitations on this utility model.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figures 1-4In this embodiment of the utility model, an external fixing component 1 is included. An internal cavity 15 is formed on the inner wall of the external fixing component 1. An internal support component 2 is provided on the inner wall of the internal cavity 15. The external fixing component 1 includes an external fixing ring 11. A bottom connecting ring 12 is fixedly connected to the outer wall of the external fixing ring 11. An external support filter 14 is fixedly connected to the bottom of the external fixing ring 11. The internal cavity 15 is formed inside the external support filter 14. The internal support component 2 includes an internal fixing ring 21. A top connecting ring 22 is fixedly connected to the outer wall of the internal fixing ring 21. A plurality of support columns 24 are uniformly fixedly connected to the bottom of the internal fixing ring 21. A base plate 26 is fixedly connected to the bottom of the plurality of support columns 24.

[0018] Multiple reinforcing rings 25 are fixedly connected to the top outer walls of multiple support columns 24. Multiple through-threaded holes 23 are evenly distributed through the top of the top connecting ring 22. Connecting bolts 13 are fixedly connected to the top of the bottom connecting ring 12, which corresponds to the positions of the multiple through-threaded holes 23. Each connecting bolt 13 is movably connected through the corresponding through-threaded hole 23. A locking nut 3 is threaded to one end of each connecting bolt 13 that passes through the through-threaded hole 23.

[0019] The outer diameter of the top connecting ring 22 matches the outer diameter of the bottom connecting ring 12. The outer diameter of the base plate 26 is smaller than the inner diameter of the inner cavity 15. The distance between the top and bottom of the multiple support columns 24 is smaller than the height distance formed between the top and bottom of the inner cavity 15.

[0020] In filtration operations, filter bags are commonly used. These filter bags require external support devices for support. Common filter bags often have the support components directly inserted inside, which can easily lead to the filter bag detaching or external devices contaminating the bag. This device, however, inserts the inner support component 2 inside the filter bag, and then inserts both the inner support component 2 and the filter bag into the internal cavity 15 of the outer fixing component 1. The locking nut 3 and connecting bolt 13 limit the movement of the outer fixing component 1 and the inner support component 2, while also locking the filter bag in place. During use, filtration is performed through the filter bag, and the outer wall of the filter bag is isolated by the external support filter screen 14.

[0021] Meanwhile, the materials of the inner support component 2 and the outer fixing component 1 can be optimized during use. For example, high-temperature resistant and corrosion-resistant alloy materials can be used to make key components such as the outer fixing ring 11, the inner fixing ring 21, and the support column 24 to improve the stability and service life of the entire support structure in high-temperature environments. Additionally, an anti-stick coating can be applied to the surface of the outer support filter screen 14 to reduce material adhesion and accumulation on the filter screen, further improving filtration efficiency.

[0022] The working principle of this invention is as follows: In practical applications, the inner support component 2 is first inserted into the filter bag to provide internal support and prevent deformation or damage to the filter bag under the impact of high-temperature airflow or materials. Then, the inner support component 2 with the filter bag is inserted into the internal cavity 15 of the outer fixing component 1, and the inner support component 2 and the outer fixing component 1 are tightly connected together by the tightening action of the connecting bolts 13 and the locking nuts 3. This design not only ensures the stable installation of the filter bag, but also effectively isolates and protects the outer wall of the filter bag through the external support filter screen 14, avoiding direct contact and contamination of the filter bag by external pollutants. During operation, the high-temperature airflow or material first undergoes preliminary filtration and isolation through the external support filter screen 14, and then enters the filter bag for fine filtration. Because the filter bag is firmly clamped between the inner support component 2 and the outer fixing component 1, it can maintain stable filtration performance and shape. At the same time, the split design makes the replacement and cleaning of the filter bag more convenient and quick, reducing maintenance costs and time. In summary, the high-temperature filter media support structure of this utility model, through its unique design and working principle, demonstrates excellent performance and stability in high-temperature filtration operations.
