Therefore, it is understood that these terms can be used interchangeably where appropriate, so that the embodiments described can be implemented in a different order, unless otherwise specified in the drawings or descriptions.

[0025] In this application, a "module" or "unit" refers to a computer program or part of a computer program that has a specific function and works in conjunction with other related parts to achieve a predetermined goal. These modules or units can be implemented by software, hardware (such as processing circuits or memories), or a combination of the two.

[0026] The technical solutions in this application will be described in detail below in conjunction with the accompanying drawings in the embodiments. It should be noted that the embodiments described are only part of this application, not all embodiments. In the following description, the "some embodiments" mentioned are only a subset of all possible embodiments, which may be the same or different subsets, and different embodiments can be combined with each other without conflict.

[0027] Figure 1 This is a flow chart of a method for setting a filter element protective layer provided in an embodiment of the present application. Figure 1 The filter element protective layer setting method provided in the embodiment of the present application may include the following steps 101 to 104:

[0028] Step 101: obtaining an initial filter material having an initial resistance less than or equal to 30 Pa, wherein the initial filter material is made of a coarse fiber non-woven fabric;

[0029] In some examples, the initial resistance is the resistance encountered by air when passing through the filter material, usually in Pascals (Pa). The lower the initial resistance, the smoother the air flow and the higher the operating efficiency of the equipment. For the initial filter material, its initial resistance is required to be less than or equal to 30 Pa to ensure that the filter element does not generate excessive airflow resistance during initial use, affecting the operation of the equipment. The initial filter material is the original material used for the protective layer of the filter element, and is the filter material before further processing or customization. Non-woven fabric is a fabric made by non-woven processes (such as spinning, compression, etc.), which has high air permeability and filtration performance; coarse fiber non-woven fabric refers to non-woven fabric with coarser fibers, which usually has better pressure resistance and filtration performance, and is suitable for filtering large particulate matter in the air.

[0030] By implementing step 101, using a coarse fiber non-woven fabric material with an initial resistance less than or equal to 30 Pa, the airflow resistance of the filter device is effectively reduced, the smoothness of the air flow is ensured, and the efficiency of the equipment is not affected by airflow obstruction during operation, thereby reducing the burden on the inhalation equipment; the coarse fiber non-woven fabric has good filtering performance, can effectively capture large particles of impurities in the air, while avoiding the influence of fine impurities on the system, and providing a stable filtering effect.

[0031] Step 102 , screening the shape, size, and thickness of the initial filter material according to the filter element shape, filter element size, and filter element installation gap of the target filter element to obtain a finalized filter material;

[0032] In some examples, a target filter element is a filter element designed and used for a specific device or system. It typically refers to the filter component to be installed and protected. The target filter element's function is to protect the device from contamination and damage by filtering particulate matter, pollutants, or impurities from the air. The filter element shape refers to the geometric form of the target filter element, which may be cylindrical, conical, or other shapes. The filter element shape determines how the filter material fits on the filter element surface, affecting overall installation effectiveness and filtration efficiency. The filter element size refers to the physical dimensions of the target filter element, such as length, width, or diameter. The filter element size must match the filter installation space and design requirements to ensure proper installation and use. The filter element installation clearance is the gap or spacing between the target filter element and the installation component (such as the equipment housing). The size of the installation clearance must take into account the thickness of the filter material to ensure that the filter material can be smoothly installed on the outer surface of the filter element without obstructing airflow. Material shape, material size, and material thickness refer to the adjustment of the filter material's shape, size, and thickness based on the specific shape and size of the target filter element during initial filter material screening to ensure it precisely fits the filter element. Different shapes, sizes, and thicknesses can optimize filtration effectiveness and align with the design requirements of the target filter element. Shaped filter materials are the final filter materials obtained after screening and customization. Shaped filter materials are adjusted according to the shape, size and installation gap of the target filter element to ensure that they can function stably and effectively on the surface of the filter element.

[0033] Through the implementation of step 102, the initial filter material is screened according to the shape, size and installation gap of the target filter element to ensure that the selected material can perfectly fit the target filter element, thereby enhancing the close fit between the filter material and the filter element, thereby improving the filtering effect and avoiding air leakage caused by improper installation.

[0034] Step 103, sewing the Velcro hook strips to the edge overlapping area of ​​the shaped filter material to obtain the target filter material to be used;

[0035] In some examples, Velcro hook strips are a component form of Velcro, and the surface is covered with tiny and tough hook-shaped fiber structures. This design gives it strong adhesion and can be tightly combined with non-woven fabrics. Compared with traditional fixing methods, such as rivets and glue, it does not require complicated installation tools and processes, and can be connected with just a light press. It is convenient for quick assembly in the production process and facilitates disassembly operations during subsequent maintenance, greatly improving production efficiency and the convenience of equipment maintenance. The edge overlapping area is the area formed by properly stacking the edge parts of the material during the processing of the shaped filter material in order to achieve better sealing, connection stability and adapt to the installation of Velcro hook noodles. On the one hand, this area provides sufficient attachment area for the Velcro hook noodles to ensure that the two are firmly connected and prevent separation due to airflow impact, vibration and other factors during equipment operation. On the other hand, through precise overlapping design, it can effectively prevent air from bypassing the filter layer from the edge gap of the material, thereby ensuring the integrity of the filtration effect. Taking cylindrical shaped filter materials as an example, the circumferential edges of one or both ends are usually overlapped with an appropriate width (such as 1.5% of the overall width) to meet the subsequent Velcro installation and sealing requirements. The target filter material goes through a series of processing steps, including screening the initial filter material according to the target filter element parameters, customizing the shape and size according to installation requirements, and then sewing the Velcro hook noodles to the edge overlapping area. The final form is a complete filter material that can be directly used for installation on the target filter element. It integrates multiple functions such as filtration, adaptation, and convenient installation. It is the core product of the entire filter element protection layer technology solution, which is directly related to the protection effect of the target filter element and the air intake quality of the suction equipment.

[0036] For example, for a cylindrical target filter element, the shape and size of the target filter material can be found in Figure 2 The target filter material shown, Figure 2 The units of the digital dimensions are all millimeters; for conical target filter elements, the shape and size of the target filter material can be found in Figure 3 The target filter material shown, Figure 3 The units of the digital dimensions are all millimeters.

[0037] By implementing step 103, the Velcro hook strips are sewn to the edge of the shaped filter material, which can achieve quick and stable fixation during the installation and disassembly process, avoiding the complexity and installation time of traditional fixing methods, and saving labor costs; and the design of the Velcro ensures that the filter material can be firmly attached to the surface of the filter element and will not fall off or shift under high load or vibration conditions, thereby maintaining a stable filtering effect.

[0038] Step 104: fix the target filter material to be used on the outer surface of the target filter element by wrapping it around the Velcro hooks;

[0039] In some examples, the characteristics of the Velcro hook noodles are utilized to tightly fit the target filter material to be used on the outer surface of the target filter element in a winding manner, thereby achieving stable installation. The advantages of Velcro, which is convenient and can be opened and closed repeatedly, are fully utilized. Compared with traditional fixing methods such as bundling and welding, the operation is extremely simple. It is only necessary to place the side of the target filter material with the Velcro hook noodles close to the target filter element, and then wrap it along the outer contour of the filter element so that the Velcro hook noodles are tightly adhered to the Velcro velvet noodles or the non-woven fabric itself pre-sewn on the other side of the filter material, and the installation can be quickly completed.

[0040] By implementing step 104, the target filter material can be easily installed on the filter element and can be quickly disassembled during maintenance, thereby reducing downtime and improving equipment maintenance efficiency.

[0041] In summary, the embodiment of the present application uses a coarse fiber non-woven fabric material with an initial resistance less than or equal to 30 Pa, which can effectively reduce the airflow resistance, ensure the smoothness of air flow and the efficient operation of the equipment, so that the filter can provide a lower airflow resistance in the initial use, avoid affecting the operating efficiency of the equipment due to excessively high initial resistance, reduce the burden on the suction equipment, and extend the service life of the equipment; according to the specific shape, size and installation gap of the target filter element, the appropriate initial filter material is screened, so that each filter element can get a customized protective layer design, which not only enhances the protection effect, but also ensures the adaptability of the material and the convenience of installation; by using Velcro hook noodles to fix the protective layer on the surface of the filter element, it can be easily installed and removed. Compared with the traditional fixing method, the maintenance and replacement process is greatly simplified. Velcro can firmly fix the protective layer, and it is also convenient for quick removal during maintenance, saving time and manpower. In summary, the filter element protective layer setting method provided in the embodiment of the present application effectively reduces airflow resistance, extends the life of the equipment, simplifies the installation and maintenance process, and improves the operating efficiency and convenience of the equipment by selecting a coarse fiber non-woven fabric material with low initial resistance, a customized protective layer design and a Velcro fixing method.

[0042] In some embodiments, the aforementioned filter element protective layer setting method may further include: in response to a protective layer replacement signal, removing the used target filter material and fixing the target filter material to be used to the outer surface of the target filter element by wrapping it around Velcro hooks.

[0043] In some examples, the protective layer replacement signal is a prompt signal sent by the system or equipment, indicating that the protective layer of the filter element (i.e., the filter material) needs to be replaced. This signal can be based on the filter's working time, working pressure, decline in filtering effect, or changes in other monitoring parameters, to notify the operator or automated equipment to perform maintenance and replacement in a timely manner. The used target filter material is the filter material that has been installed and used for a period of time. These materials usually need to be replaced or cleaned due to the accumulation of dust, impurities or loss of some filtering effect. The target filter material to be used is new or cleaned filter material that has been prepared and is waiting to be installed. After receiving the protective layer replacement signal, these materials can replace the used filter material and continue to perform the filtering work.

[0044] For example, a pressure pipe is installed before and after the air intake chamber (before and after the filter element). The pressure before and after the filter element is transmitted to the distributed control system (DCS) through a differential pressure transmitter. When the pressure difference reaches a certain limit, the DCS issues an alarm, indicating that the pressure difference before and after the filter element exceeds the limit and needs to be replaced.

[0045] Through the implementation of the above embodiment, in response to the protective layer replacement signal, the used material can be quickly removed and replaced with the stand-by material. With the convenient feature of Velcro, there is no need to shut down the equipment and online operation can be achieved, which greatly improves the operation and maintenance efficiency and ensures production continuity. Especially for large-scale production lines, it can avoid the huge losses caused by local shutdowns and restore the high-quality air intake filtration state in time.

[0046] In some embodiments, the aforementioned filter element protective layer setting method may further include: washing and drying the used target filter material to obtain the target filter material to be used.

[0047] For example, the used target filter material can be cleaned to remove accumulated dust, impurities, and other contaminants, and then completely dried using a drying device to obtain the target filter material ready for use. The cleaning step typically uses water, chemical detergents, or compressed air, while drying is accomplished using hot air, an oven, or other equipment to ensure the filter material is dry and its structure is restored.

[0048] Through the implementation of the above embodiments, the used materials can be cleaned, dried and reused, which can reduce the consumption of raw materials and save procurement costs. At the same time, it can reduce the generation of waste filter materials, conform to the concept of environmental protection, enhance the environmental image of the enterprise, and provide dual guarantees of economic and environmental benefits for the long-term stable operation of the enterprise.

[0049] In some embodiments, before step 103, the filter element protective layer setting method may further include: performing ultrasonic pretreatment on the edge overlapping area to cause the fiber surface of the edge overlapping area to slightly melt.

[0050] For example, ultrasonic pretreatment uses the vibration of high-frequency sound waves to treat the edge overlapping areas of the filter material. Ultrasonic waves can cause micro-melting of the surface of the material through vibration, improve its surface contact performance, enhance subsequent stitching or bonding effects, and thus improve the stability and adhesion of the material.

[0051] Through the implementation of the above embodiment, the edge overlapping area is ultrasonically pretreated before sewing the Velcro, so that the fiber surface is slightly melted, which can increase the fusion between the fibers, make the Velcro and the material more tightly combined, and further enhance the adhesion. Even in the environment of strong airflow impact and severe equipment vibration, it can still maintain a firm connection to prevent the filter material from accidentally detaching.

[0052] In some embodiments, before step 102, the filter element protective layer setting method may further include: scanning the target filter element by three-dimensional laser to obtain the filter element shape, filter element size and filter element installation gap of the target filter element.

[0053] For example, three-dimensional laser is a technical means that uses the principle of laser ranging and combines precise scanning technology to quickly and accurately obtain three-dimensional spatial information of objects. After the three-dimensional laser contacts the surface of the target filter element, part of the laser will be reflected back. By measuring the time or phase change of the laser's round trip, the distance from the laser irradiation point to the scanning device is calculated; at the same time, the scanning device continuously changes the emission direction of the laser, performs a full-range and multi-angle scan of the target filter element, and collects massive point cloud data. This data contains the coordinate information of each position on the surface of the target filter element, and can then be processed through professional software to reconstruct an accurate three-dimensional model of the target filter element, from which key parameters such as the filter element shape, size and installation gap are directly extracted, providing an accurate basis for the subsequent customization of the adapted initial filter material.

[0054] Through the implementation of the above embodiment, three-dimensional laser scanning is used to scan the target filter element to obtain accurate shape, size and installation gap data. Compared with the existing technology, it is more accurate and faster, providing a reliable basis for subsequent material screening and customization, ensuring that the produced filter element protective layer fits the target filter element tightly, optimizing the filtering effect and installation convenience.

[0055] In some embodiments, photocatalytic nanoparticles are added during the preparation of the coarse fiber non-woven fabric.

[0056] For example, photocatalyst nanoparticles are a type of nanoscale material that can exert a catalytic effect under light, usually composed of substances such as titanium dioxide (TiO2) and zinc oxide (ZnO); under the action of light, photocatalyst nanoparticles can promote chemical reactions, produce redox reactions, degrade organic pollutants or kill bacteria, and have self-cleaning, antibacterial, and anti-pollution functions.

[0057] Through the implementation of the above embodiments, the crude fiber non-woven fabric is prepared by adding photocatalytic nanoparticles to give the material photocatalytic properties; under light, it can decompose adsorbed organic pollutants (such as volatile organic compounds), assist physical filtration, and further improve the quality of intake air purification, providing better quality air for industrial scenarios with strict requirements on air quality (such as electronic chip manufacturing workshops), thereby ensuring product quality.

[0058] In some embodiments, the aforementioned filter element protective layer setting method may further include: spraying fluorescent marking paint in a grid pattern on the outer surface of the target filter material to be used.

[0059] For example, fluorescent marking paint is a paint containing fluorescent substances that can emit bright light under ultraviolet light or specific light sources, making it easy to observe and locate in low light or special environments. Fluorescent paint can enhance visibility and recognition. Coating it on the outer surface of the target filter material can provide convenient identification for subsequent inspection, maintenance or monitoring.

[0060] Through the implementation of the above embodiment, the fluorescent marking paint is sprayed in a grid pattern on the outer surface of the material to be used. During daily inspections or maintenance, staff can quickly locate the filter material with the help of a specific light source, especially in the dim light environment inside the equipment, so as to facilitate timely detection of abnormal conditions of the filter material (such as damage, displacement), improve maintenance efficiency, and ensure stable operation of the equipment.
