Description

Technical Field

[0001] This utility model belongs to the field of filter material technology, specifically a reinforced and strengthened high-temperature resistant filter material. Background Technology

[0002] In modern industry, numerous high-temperature operating scenarios place an indispensable demand on filter media. For example, in steel smelting, high-temperature furnaces generate large amounts of dust-laden waste gas, often reaching temperatures of several hundred degrees Celsius. In cement production, the flue gas emitted from kilns is not only high in temperature but also contains complex chemical components. Furthermore, waste incineration power generation produces high-temperature flue gas carrying various dust particles, acidic gases, and other pollutants. In these high-temperature industrial scenarios, filter media plays a crucial role in filtering dust and purifying gases, ensuring a safe production environment and reducing pollutant emissions. However, traditional filter media often fall short in the face of such harsh high-temperature conditions. When the temperature exceeds a certain limit, the fiber structure of ordinary filter media undergoes thermal degradation, resulting in a significant decrease in strength, making the filter media prone to breakage and shortening its service life. The filter media's chemical stability deteriorates rapidly at high temperatures, making it prone to chemical reactions with acidic or alkaline substances in the flue gas, further damaging the filter media. This not only reduces filtration efficiency, failing to meet environmental emission standards, but also requires frequent filter media replacements, increasing production costs and maintenance workload for enterprises. Against this backdrop, the innovative design of reinforced and strengthened high-temperature resistant filter media has emerged. Like a ray of light in the darkness, it brings new hope for solving the problem of high-temperature industrial filtration. This innovative design aims to fundamentally improve the high-temperature resistance, mechanical strength, and chemical stability of the filter media. By selecting new materials, optimizing structural design, and adopting advanced processing technology, the filter media can operate stably and efficiently in high-temperature environments, providing strong support for the environmental protection and sustainable development of high-temperature industrial production.

[0003] Meanwhile, a high-temperature resistant needle-punched and hydroentangled composite filter material with announcement number CN212073233U is disclosed, which relates to the field of filter material technology for high-temperature flue gas dust removal equipment. It includes an expanded glass fiber base cloth, one side of which is provided with an aramid fiber web, and the other side of which is provided with an aramid-PA6T and PTFE fiber web. The dust-facing side of the aramid-PA6T and PTFE fiber web is provided with a PTFE membrane.

[0004] Although the aforementioned high-temperature resistant needle-punched and hydroentangled composite filter media adopts a needle-punched and hydroentangled composite process during use, the rigid hooked needles during the needle-punching process may still cause some damage to the fibers, especially for brittle glass fibers, which may affect the flexibility and service life of the filter media. The hydroentanglement process is only suitable for short fiber materials. If long fibers are used in this filter media, they may become entangled, thus affecting the uniformity and performance of the filter media.

[0005] Therefore, a reinforced and strengthened high-temperature resistant filter material is proposed to address the above problems. Utility Model Content

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 an enhanced and reinforced high-temperature resistant filter material, including a fixing frame 4. The fixing frame 4 has a threaded rod 5 spirally arranged inside, and a rotating shaft 11 spirally arranged outside the threaded rod 5. A pressure plate 12 is fixedly arranged outside the rotating shaft 11. A connecting column 13 is fixedly arranged on the right end face of the pressure plate 12. A limiting frame 8 is fixedly arranged on the right end face of the connecting column 13. Through the threaded rod 5, the rotating shaft 11 can be driven to move along the axial direction of the rod, so that the pressure plate 12 forms a uniform and controllable pressure on the filter material, avoiding excessive local compressive stress that damages the filter material, or insufficient pressure that causes the filter material to loosen. Through the connecting column 13 and the pressure plate 12, a frame-like limiting can be formed from the edge and outer periphery of the filter material, further limiting the thermal expansion and deformation of the filter material at high temperature, ensuring that the filter material always maintains a flat filter surface and maintains a stable filter channel.

[0027] In this embodiment, a limiting block 9 is slidably provided inside the limiting frame 8, and a pressure plate 10 is fixedly provided on the right end face of the limiting block 9. The limiting frame 8 can limit the range of motion of the limiting block 9.

[0028] A spring 14 is fixedly installed on the lower end face of the pressure plate 12, a telescopic rod 15 is fixedly installed on the lower end face of the spring 14, and a filter plate body 1 is fixedly installed on the lower end face of the telescopic rod 15. Through the spring 14 and the telescopic rod 15, the filter material is given a certain degree of flexibility and adjustability, so that the filter material can better adapt to different working environments and pressure changes.

[0029] A pre-filter anti-sticking layer 16 is fixedly provided inside the filter plate body 1, and a filter layer 17 is fixedly provided on the lower end face of the pre-filter anti-sticking layer 16. The pre-filter anti-sticking layer 16 can prevent impurities from sticking together, ensure the long-term stable operation of the filter material, and provide better working conditions for the subsequent filter layer.

[0030] A silicon carbide fiber layer 18 is fixedly provided on the lower end face of the filter layer 17, and an ultrafine glass fiber layer 19 is fixedly provided on the lower end face of the silicon carbide fiber layer 18. Through the silicon carbide fiber layer 18 and the ultrafine glass fiber layer 19, impurities of different sizes and properties can be intercepted more effectively, thereby improving the filtration accuracy of the filter media.

[0031] A second filter layer 20 is fixedly provided on the lower end face of the ultrafine glass fiber layer 19, and a support layer 21 is fixedly provided on the lower end face of the second filter layer 20. The support layer 21 provides structural support for the entire filter plate body 1, ensuring the stability and reliability of the filter material during operation.

[0032] A connecting plate 2 is fixedly provided on the lower end face of the fixing frame 4. A threaded post 3 is fixedly provided inside the connecting plate 2. A rotating handle 6 is fixedly provided on the upper end face of the threaded rod 5. An anti-slip strip 7 is fixedly provided on the outer side of the rotating handle 6. The connecting plate 2 and the threaded post 3 provide a more stable installation method for the fixing frame 4, ensuring that the filter material will not loosen due to vibration or external force during operation, thus enhancing the overall stability of the filter material.

[0033] The working principle and process of a reinforced and strengthened high-temperature resistant filter material: First, rotating the handle 6 causes the threaded rod 5 to rotate spirally inside the fixed frame 4. Since the threaded rod 5 is spirally equipped with a rotating shaft 11 on its outer side, the rotating shaft 11 will move along with the threaded rod 5 when it rotates. A pressure plate 12 is fixed on the outer side of the rotating shaft 11, and the pressure plate 12 will move together with the rotating shaft 11. The connecting post 13 and the limiting frame 8 on the right end face of the pressure plate 12 will also move accordingly. At the same time, a limiting block 9 is slidably provided inside the limiting frame 8, and the pressure plate 10 on the left end face of the limiting block 9 will also move under the restriction of the limiting frame 8. During this process, the pressure plate 10 and the pressure plate 12... 2. The filter plate body 1 is initially fixed by mutual cooperation. In addition, the connecting plate 2 on the lower end face of the fixing frame 4 and the internal threaded post 3 can be used to install the entire filter media device onto the corresponding equipment to ensure the stability of the filter media during operation. The pre-filtration anti-sticking layer 16 inside the filter plate body 1 begins to play its role. When gas or liquid containing impurities enters the filter plate body 1, the pre-filtration anti-sticking layer 16 can pre-intercept some larger impurity particles, and its anti-sticking performance can effectively prevent impurities from adhering to the surface of the filter media, ensuring the smooth progress of the subsequent filtration process. After pre-filtration... After initial filtration by the anti-sticking layer 16, the gas or liquid enters the first filter layer 17, which further filters smaller impurities, improving the filtration effect. Next, the gas or liquid reaches the silicon carbide fiber layer 18, which has good high-temperature resistance and high strength, enabling it to work stably in high-temperature environments and further filtering impurities. Subsequently, the ultrafine glass fiber layer 19 intercepts even finer impurities; its dense structure effectively captures tiny particles. After that, the gas or liquid enters the second filter layer 20 for final fine filtration, ensuring that the output gas or liquid reaches a high purity. During the filtration process, the spring 14 and the telescopic rod 15 on the lower end face of the pressure plate 12 play an important role. The spring 14 can buffer the pressure and vibration generated during the filtration process, protecting the filter plate body 1 from damage. The telescopic rod 15 ensures the stability of the extension and retraction direction of the spring 14, ensuring the stability of the filter plate body 1 during operation. Through this series of processes, the reinforced and high-temperature resistant filter material can efficiently and stably complete the filtration task, providing reliable filtration guarantees for industrial production and related fields.
