Description

Technical Field

[0001] This utility model relates to the field of filter material technology, and in particular to a multifunctional filter material that integrates VOCs purification and dust removal. Background Technology

[0002] In the fields of industrial production and environmental protection, the purification and efficient removal of VOCs and dust are key to ensuring air quality and reducing health risks. With increasingly stringent environmental regulations and higher requirements for production environments from enterprises, integrated devices that combine VOCs purification and dust removal functions are widely used in industries such as chemical, coating, and printing. Their performance directly affects the efficiency of pollutant treatment and production and operating costs.

[0003] In existing technologies, the filter media used in VOCs purification and dust removal devices are mostly integral structures, with complex installation and fixing methods. They typically require specialized tools to disassemble multiple connectors to replace or recycle the filter media, which is not only cumbersome and time-consuming but also increases the workload of maintenance personnel, leading to higher downtime maintenance costs. Furthermore, the structural design of traditional filter media is relatively simple, often making it difficult to balance dust removal efficiency, VOCs purification effect, and their own lifespan: some filter media, while capable of capturing dust, are prone to frequent replacement due to rapid surface clogging; others, although capable of VOCs treatment, suffer from low purification efficiency due to weak catalyst adhesion and limited contact area with pollutants, and lack effective regeneration methods, resulting in significant performance degradation after long-term use and failing to meet the requirements for long-term stable operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional filter media that integrates VOCs purification and dust removal. The modular design simplifies the filter media installation and replacement process, and the three-layer structure with clear division of functions improves filtration efficiency and VOCs treatment capacity. The low-temperature heating regeneration function of the conductive layer extends the filter media's lifespan and ensures long-term stable filtration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional filter material integrating VOCs purification and dust removal, comprising a frame, with a supporting skeleton fixedly connected to both the upper and lower ends of the frame. A coarse filter layer is fixedly connected to the lower side of the upper supporting skeleton. The coarse filter layer is a high-porosity fiber material with a cross-sectional shape of X. A conductive layer is fixedly connected to the lower end of the coarse filter layer. The conductive layer has a conductive structure. A purification layer is fixedly connected to the lower end of the conductive layer. The purification layer is catalytically activated carbon fiber. A sealing plate is fixedly connected to the front end of the frame. A pin is connected to the upper front side of the sealing plate via a sliding component. A fixing rod is fixedly connected to the outer wall of the pin. A limit plate is fixedly connected to the middle of the pin. A spring is sleeved on the lower outer wall of the pin.

[0006] Furthermore, the sliding assembly includes a mounting plate fixedly connected to the upper front side of the sealing plate, a first fixing block fixedly connected to the upper front side of the mounting plate, a second fixing block fixedly connected to the lower front side of the mounting plate, a limit block fixedly connected to the middle front side of the mounting plate, and the upper outer wall of the pin slidably connected to the inner wall of the first fixing block.

[0007] Furthermore, a sealing rubber is fixedly connected to the outer wall of the support frame, and sliding plates are fixedly connected to both the left and right sides of the outer wall of the frame, with limit grooves opened on both the upper and lower sides of the sliding plates.

[0008] Furthermore, a conductive interface is fixedly connected to the middle of the sealing plate, and the conductive interface passes through the sealing plate and is connected to the conductive layer.

[0009] Furthermore, magnetic strips are fixedly connected to both the upper and lower ends of the rear side of the sealing plate, and a handle is fixedly connected to the lower end of the front side of the sealing plate.

[0010] Furthermore, the upper end of the spring is connected to the lower side of the limiting plate, and the lower end of the spring is connected to the upper side of the second fixing block.

[0011] Furthermore, the lower end of the pin is slidably connected to the inner wall of the second fixing block.

[0012] Furthermore, the limiting block prevents the pin from slipping out by restricting the position of the limiting plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the combination of modular design with sliding connection, magnetic initial fixation and pin final fixation greatly simplifies the filter material replacement and recycling process, and reduces the difficulty and time cost of maintenance operations.

[0015] 2. In this utility model, a three-layer structure design is adopted with clear division of labor. The coarse filter layer efficiently captures dust of different particle sizes while preventing the surface from clogging too quickly. The conduction layer reduces resistance by enhancing capture through electrostatics. The purification layer improves the VOCs treatment efficiency. At the same time, the low-temperature heating regeneration function of the conduction layer can restore the performance of the filter material, extend its service life, and ensure a long-term stable filtration effect.

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.

A coarse filter layer 7 is fixedly connected to the lower side of the upper supporting skeleton 6. The coarse filter layer 7 is a high-porosity fiber material with a cross-sectional shape resembling a star. A conductive layer 8 is fixedly connected to the lower end of the coarse filter layer 7. The conductive layer 8 has a conductive structure. A purification layer 9 is fixedly connected to the lower end of the conductive layer 8. The purification layer 9 is catalytically activated carbon fiber. A sealing plate 2 is fixedly connected to the front end of the frame 1.

A second fixing block 19 is fixedly connected to the lower front end of the mounting plate 13. A limiting block 17 is fixedly connected to the middle front side of the mounting plate 13. The upper outer wall of the pin 15 is slidably connected to the inner wall of the first fixing block 14. The lower outer wall of the pin 15 is slidably connected to the inner wall of the second fixing block 19. A fixing rod 16 is fixedly connected to the outer wall of the pin 15. A limiting plate 20 is fixedly connected to the middle of the pin 15. The limiting block 17 prevents the pin 15 from slipping by limiting the position of the limiting plate 20. A spring 18 is sleeved on the lower outer wall of the pin 15. The upper end of the spring 18 is connected to the lower side of the limiting plate 20. The lower end of the spring 18 is connected to the upper side of the second fixing block 19. A conductive interface 11 is fixedly connected to the middle of the sealing plate 2. The conductive interface 11 passes through the sealing plate 2 and is connected to the conductive layer 8. Magnetic strips 10 are fixedly connected to both the upper and lower ends of the rear side of the sealing plate 2. A handle 12 is fixedly connected to the lower front end of the sealing plate 2.

[0023] Specifically, this device adopts a modular design, transforming the integrated filter media into standard-sized modular components. Installation and replacement of the filter media are very convenient, achieved through sliding connections between the sliding plates 3 at both ends of the frame 1 and the sliding grooves on the inner wall of the filter box. A limiting rod is provided on the inner wall of the sliding groove, and the limiting groove 4 cooperates with the limiting rod to effectively prevent the filter media from shifting during sliding. The connection is sealed with sealing rubber 5 and sealing plate 2 to ensure the airtightness of the filter box. Furthermore, the filter media is initially fixed by magnetic strips 10 adsorbing onto magnetic iron sheets on the filter box, and then further fixed by pins 15 engaging with pin holes on the filter box. This dual-fixing method ensures the stability of the filter media and facilitates its replacement and recovery.

[0024] The supporting skeletons 6 at the top and bottom of the filter media frame 1 effectively support the overall strength of the internal filter media, ensuring that the filter media will not deform or collapse during operation. This filter media adopts a three-layer structure design. The coarse filtration layer 7 is located at the air inlet end and uses high-porosity fiber material with a cross-sectional shape resembling a star (X). Its multi-layered angled design increases the probability of dust particle impact, efficiently capturing dust of different particle sizes while effectively preventing excessive surface clogging and providing pre-treated airflow to the lower layers. The middle layer is the conductive layer 8, which can be connected to a safe voltage through the conductive interface 11 to form an electric field, enhancing the electrostatic capture of particulate matter and reducing the filter media's bulk resistance. The purification layer 9 is the core functional layer. By synthesizing the catalyst into the activated carbon fiber, the specific surface area and strength of the catalyst are significantly improved, thereby increasing the contact area between VOCs molecules and the catalyst and improving reaction efficiency. The conductive layer 8 can also generate Joule heat through electrical current, providing a low-temperature heating regeneration function for the filter media. During the heating process, the adsorbed VOC molecules desorb and diffuse into the catalyst area where they are decomposed, while some carbon deposits are burned off, thus restoring the filtration performance of the filter media. This design not only extends the service life of the filter media but also ensures the efficient operation of the device.

[0025] Working Principle: This device adopts a modular design, transforming the integrated filter media into standard-sized modular components. The sliding plates 3 at both ends of the frame 1 slide and connect to grooves on the inner wall of the filter box. Limiting rods are installed on the inner wall of the grooves, and limiting grooves 4 cooperate with the limiting rods to prevent displacement. The connection is sealed by sealing rubber 5 and sealing plates 2. A magnetic strip 10 initially attracts and fixes the filter media to a magnetic iron sheet on the filter box, and then a pin 15 engages with the pin hole on the filter box for final fixation. This design facilitates filter media replacement and recycling. The supporting skeletons 6 at the upper and lower ends of the frame 1 support the overall strength of the internal filter media. The filter media has a three-layer structure. The coarse filtration layer 7 is located at the air inlet and is made of high-porosity fiber material with a cross-sectional shape resembling a star, efficiently capturing dust particles of different sizes while preventing rapid surface clogging and providing pre-treated airflow to the lower layer. The middle layer is a conductive layer 8, which can be connected to a safe voltage through a conductive interface 11 to form an electric field, enhancing the electrostatic capture of particles and reducing the filter media's resistance. The purification layer 9, as the core functional layer, incorporates the catalyst into the activated carbon fiber, increasing the specific surface area and robustness of the catalyst, thereby increasing the contact area between VOCs molecules and the catalyst and improving reaction efficiency. The conductive layer 8 can also generate Joule heat through electrical current to provide low-temperature heating and regeneration for the filter media. The heat causes the adsorbed VOCs molecules to desorb and diffuse into the catalyst area for decomposition, while simultaneously burning off some carbon deposits and restoring the filtration performance of the filter media.
