Description

Technical Field

[0001] This application relates to the field of filter element structure technology, and in particular to a bendable filter screen and filtration system. Background Technology

[0002] Filters are functional components in filtration systems that play a role in interception. They can separate impurities, particles, or pollutants in the medium through their own pore structure, ensuring the stable operation of downstream equipment and the purity of the medium. They are widely used in water treatment, air purification, industrial fluid filtration, and other scenarios.

[0003] In practical applications, cylindrical filters, with their spiral-shaped structure, provide circumferential protection for their surrounding components and are compatible with the installation requirements of most cylindrical containers or pipeline filtration systems, making them a commonly used filter type in industrial and civilian settings. However, most existing cylindrical filters are manufactured using a one-piece molding method, meaning they are directly processed into a cylindrical structure. This results in numerous ineffective gaps when stacked, failing to fully utilize space and significantly reducing the load capacity per shipment, leading to low transportation efficiency and high transportation costs. Furthermore, the cylindrical filter structure has relatively weak stability, and its walls are at high risk of deformation due to bumps and collisions during transportation. Therefore, the need for more packaging and protective materials further increases the overall packaging and transportation costs. Utility Model Content

[0050] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0051] Please see Figure 1 The first aspect of this application provides a bendable filter (hereinafter referred to as a filter), comprising: a filter body 10, a flexible layer 20 and two connectors 30.

[0052] The flexible layer 20 is disposed on at least one side of the filter body 10 along the first direction x; the connector 30 includes at least two and is disposed on both sides of the filter body 10 along the second direction y; the first direction x is perpendicular to the second direction y; the filter body 10 can be bent into a cylindrical structure in which the two connectors 30 are mutually constrained and connected.

[0053] In one embodiment, in the cylindrical structure, the two connecting members 30 can be mutually positioned along the thickness direction z; the thickness direction z is the thickness direction of the filter body 10; the thickness direction z is perpendicular to the first direction x and the second direction y.

[0054] In this embodiment, the first direction x is as follows: Figure 1 and Figure 2 In the context of the x-axis, the first direction x can be understood as the axial direction of the cylindrical structure formed after the filter screen is bent. Normally, when the filter screen is placed vertically (i.e., the end face of the filter screen body 10 along the first direction x is placed on a horizontal plane), the first direction x is vertical. However, in some cases, when the filter screen is not placed vertically, the first direction x should be based on the axial direction of the cylindrical filter screen.

[0055] The second direction is as follows Figure 1 and Figure 2 In the y-axis direction, when the filter screen is placed vertically, the first direction y is located in the horizontal plane, and it is also the circumferential direction of the cylindrical structure after the filter screen is bent.

[0056] thickness direction z such Figure 1 and Figure 2 In the z-axis direction, when the filter screen is placed vertically, the first direction z is located in the horizontal plane, and it is also the radial direction of the cylindrical structure after the filter screen is bent.

[0057] like Figure 2As shown, during transportation and sales, the filter body 10 can be laid flat, allowing multiple filters to be directly stacked, thereby improving space utilization and reducing the amount of packaging protective material used. In use, the filter body 10 can be bent so that two connectors 30 interlock, thus maintaining its position within the cylindrical structure through the interlocking of the connectors 30, as shown. Figure 1 As shown.

[0058] In the cylindrical structure, the two connecting parts 30 are mutually restrained along the thickness direction z. That is, when a force is applied to the two connecting parts 30 along the thickness direction z, the two connecting parts 30 cannot be separated. This can improve the stability of the cylindrical structure and reduce the risk of the cylindrical structure being damaged or unable to be used normally due to the expansion of the cylindrical structure caused by external force or the elastic force of the filter itself spreading in the flat direction during use.

[0059] As one implementation, the flexible layer 20 can serve as a sealing structure, which can seal both sides of the filter body 10 along the first direction x, ensuring the airtightness of the filter body 10 after it is connected to the filter system.

[0060] In this design, the flexible layer 20 is elastic and can bend synchronously with the bending of the filter body 10. For example, as Figure 1 As shown, in its cylindrical state, the flexible layer 20 is roughly formed into a ring shape; as Figure 2 As shown, in its flat state, the flexible layer 20 is generally elongated. When the filter is installed in the filtration system, both sides of the filter along the axial direction abut against the components in the filtration system to ensure that airflow passes only through the filter; therefore, at least one side of the filter along the axial direction, i.e., at least one side along the first direction x, will be subjected to the compressive force of other components. In this embodiment, the flexible layer 20 can withstand the aforementioned compressive force, while filling the gap between the filter body 10 and the components, and fixing the position of the filter body 10 through the frictional force generated by the compression, thereby improving the stability of the filter body 10 after installation.

[0061] As one implementation method, flexible layers 20 are provided on both sides of the filter body 10 along the first direction x, so as to improve the protection and buffering effect of the flexible layers 20 on the filter body 10.

[0062] Preferably, the surface of the flexible layer 20 furthest from the filter body 10 is configured as an anti-slip surface, i.e., a non-smooth surface. The outer surface of the flexible layer 20 can be configured as an anti-slip surface by providing a porous structure, providing friction stripes, making it a rough surface, or using a high-friction material, etc.

[0063] It should be noted that the filter provided in this embodiment can form cylindrical structures of different diameters by varying the number of filter screens in practical applications. For example, if the length of a filter screen body 10 along the y-axis is L, then one filter screen body 10 can be used to form a cylindrical structure with a circumference of L, and two filter screen bodies 10 can be used to form a cylindrical structure with a circumference of 2L, and so on. Specifically, the connectors 30 of multiple filter screens can be connected end to end.

[0064] In one embodiment, the flexible layer 20 has a porous structure, which gives it good flexibility and increases the friction between it and the contacting components, thereby improving the stability of the filter after installation. As one implementation, the flexible layer can be a sponge layer, specifically a dense sponge. In other embodiments, the flexible layer can be made of materials such as polyurethane, rubber, or fabric.

[0065] In practical applications, the flexible layer 20 can be configured to be located in a non-effective filtration area in the filtration system after installation, so as to ensure that the flexible layer 20 does not affect the filtration effect.

[0066] In one embodiment, the filter body 10 is connected to the flexible layer 20 on both sides along the first direction x through a sealing layer.

[0067] The sealing layer can block the media flow gap between the flexible layer 20 and the filter body 10, preventing the filter media from passing through the gap and ensuring that the filter media is effectively intercepted by the filter body 10.

[0068] In one embodiment, the sealing layer is a polyurethane adhesive layer. The polyurethane adhesive layer can seal the gap between the flexible layer 20 and the filter body 10 while firmly connecting the flexible layer 20 and the filter body 10, ensuring the stability of the overall filter structure. In other embodiments, the sealing layer can also be an adhesive material such as hot melt adhesive.

[0069] In one embodiment, the thickness of the flexible layer 20 is 2-6 mm, determined based on its functional role in the overall filter structure and practical application requirements. On one hand, the flexible layer 20 needs to bend along with the filter body 10 to form a cylindrical structure, and must withstand deformation stress caused by shape transformation during bending. When the thickness is less than 2 mm, its structural strength and elasticity reserves as a porous sponge layer are insufficient, making it prone to breakage or connection failure with the filter body due to localized stress concentration during bending, thus failing to guarantee stable bending of the filter body. On the other hand, when the thickness is greater than 6 mm, the overall rigidity of the porous sponge layer increases significantly with thickness, leading to a substantial increase in bending resistance. Therefore, in this embodiment, to facilitate the bending of the flexible layer 20 along with the filter body 10 and reduce the risk of breakage, its thickness is set to 2-6 mm.

[0070] In one embodiment, in the cylindrical structure, the ratio of the height to the diameter of the filter body 10 is less than 2.5:1.

[0071] Specifically, taking a cylindrical structure with a filter body 10 having a diameter of 2R and a dimension of H along the first direction x as an example, in this embodiment, H:2R < 2.5:1. By configuring the above-mentioned height-to-diameter ratio, it is possible to avoid the center of gravity of the cylindrical structure being too high, which would affect the stability of the cylindrical structure. At the same time, it is possible to reduce the axial stress, which would affect the external pressure resistance of the cylindrical structure and improve the axial load-bearing capacity, as well as ensure that there is an effective filtration space inside the cylindrical structure.

[0072] In one embodiment, the flexible layer 20 completely covers the end face of the filter body 10 in the first direction x, so as to ensure that the flexible layer 20 can provide protection and support for the entire end face of the filter body 10.

[0073] In one embodiment, the flexible layer 20 extends out of the filter body 10 on both sides along the second direction y. Specifically, taking the total length of the filter body 10 in the flat state along the second direction y as L, in this embodiment, the length of the flexible layer 20 in the flat state along the second direction y is greater than L, so that after bending, the flexible layer 20 can extend out of the filter body 10 on both sides along the second direction y. This ensures that when bent into a cylindrical shape, the flexible layer 20 can abut against itself end to end, thereby fully covering the end face of the filter, avoiding cracks at the joints, and increasing the stability and sealing effect of the structure.

[0074] In one embodiment, the flexible layer 20 may be flush with one of the connectors 30 on one side along the second direction y, and the flexible layer 20 may extend beyond the other connector 30 on the other side along the second direction y.

[0075] In one embodiment, the flexible layer 20 extends out of the outside of one connector 30 along one side of the second direction y, and the flexible layer 20 extends out of the outside of another connector 30 along the other side of the second direction y.

[0076] refer to Figure 1 In one embodiment, the flexible layer 20 has a chamfered structure on its outer side along the thickness direction z. The outer side of the flexible layer 20 refers to the side away from the axis when the filter body 10 is bent into a cylindrical structure. The chamfered structure means that the outer side of the flexible layer 20 along the thickness direction z is configured with a rounded chamfer or a beveled chamfer. The chamfered structure softens the outer edge of the flexible layer 20 into a smoother transition surface, facilitating stretching after bending and reducing the risk of breakage during bending or long-term use.

[0077] In one embodiment, the connector 30 may be a structure such as Velcro, and multiple connectors 30 may be provided on the end face of the filter body 10 along the second direction y.

[0078] In one embodiment, the connector 30 covers the end face of the filter body 10 along the second direction y, which can reduce the number of connectors 30 and ensure the connection effect when the connectors 30 on both sides of the filter body 10 are mutually limited and connected.

[0079] In one embodiment, the connector 30 may be configured as a plate-like structure.

[0080] As one implementation method, please refer to Figure 1 , Figure 3 and Figure 4 The connector 30 is provided with a locking groove 31 and / or a locking buckle 32. Specifically, the connector 30 may include a plate-shaped or strip-shaped main body structure. The locking groove 31 and / or the locking buckle 32 are provided on this main body structure. Furthermore, the connectors 30 on both sides of the filter body 10 along the second direction y are provided with different locking structures, so that in the cylindrical structure, the locking groove 31 of one connector 30 engages with the locking buckle 32 of the other connector 30, thereby making the locking groove 31 and the locking buckle 32 mutually restrict each other along the thickness direction z and the second direction y. At this time, applying a force along the thickness direction z or applying a force along the second direction y to the two connectors 30 will not separate the two connectors 30.

[0081] In one embodiment, one connector 30 may have multiple engaging slots 31 and the other connector 30 may have multiple engaging buckles 32.

[0082] In one implementation, one of the two connectors 30 may have a plurality of engaging slots 31 and a plurality of engaging buckles 32 provided on one connector 30, and the other connector 30 may have a plurality of engaging slots 31 and a plurality of engaging buckles 32 provided on the other connector 30.

[0083] In this embodiment, when the engaging groove 31 and the engaging buckle 32 engage, the engaging groove 31 limits the engaging buckle 32 in the thickness direction z and the second direction y.

[0084] In a more advanced embodiment, the engaging groove 31 includes an inlet / outlet area 311 and a limiting area 312; the inlet / outlet area 311 and the limiting area 312 are interconnected and arranged along the first direction x; when the engaging buckle 32 engages with the engaging groove 31, the engaging buckle 32 passes through the inlet / outlet area 311 and moves along the first direction x into the limiting area 312 to engage with the limiting area 312.

[0085] Similarly, when the latch 32 is released from the latching groove 31, the latch 32 moves from the limiting area 312 to the entry / exit area 311 along the first direction x, and then can separate from the latching groove 31 along the second direction.

[0086] In practical applications, the engaging groove 31 located at the top edge of the connector 30 can only be provided with a limiting area 312, that is, the blank area above the engaging groove 31 at the top edge serves as the entry and exit area for the engaging buckle 32 to align with the limiting area 312.

[0087] In this embodiment, at least one limiting area 312 and the latching buckle 32 form a unidirectional limiting along the first direction x after they are engaged, such as a downward limiting. This means that after the limiting area 312 and the latching buckle 32 are engaged, the latching buckle 32 can only move upward relative to the limiting area 312 to release the engagement, and cannot move further downward. This can play a role in limiting the travel during the engagement process between the latching buckle 32 and the latching groove 31, and prevent the latching buckle 32 from moving excessively and becoming misaligned.

[0088] In one embodiment, a marker 33 is provided on the connector 30; when the two connectors 30 abut each other and the markers 33 of the two connectors 30 are flush, the latch 32 is located in the entry / exit area 311.

[0089] In this embodiment, the marker 33 is located on the outer side of the connector 30 along the thickness direction z. The marker 33 can be identified by the user when installing the filter to determine whether the bending direction of the filter is correct and whether the locking buckle 32 is aligned with the inlet / outlet area 311 during the locking process.

[0090] As one implementation, the snap fastener 32 can be a dovetail buckle structure, and correspondingly, the limiting area 312 can be a dovetail groove structure.

[0091] In one embodiment, the connector 30 is provided with sealing strips 34 or sealing grooves 35 on both sides along the thickness direction z; in the cylindrical structure, the sealing strip 34 of one connector 30 is inserted into the sealing groove 35 of another connector 30.

[0092] The sealing strip 34, when inserted into the sealing groove 35, increases the sealing performance along the thickness direction z after the two connectors 30 are engaged. In this embodiment, the sealing groove 35 and the sealing strip 34 can be configured to penetrate the connector 30 along the first direction.

[0093] In one embodiment, a functional layer is further included; the functional layer is disposed on the side of the filter body 10 along the thickness direction z; two connectors 30 are respectively connected to the two sides of the functional layer along the second direction y. The functional layer can increase the functionality of the filter and provide protection for the side of the filter body 10.

[0094] For example, a functional layer can be disposed on the outside of the filter body 10 to provide protection for the outside of the filter body 10, while also performing preliminary filtration. Specifically, the functional layer may include one or more of an activated carbon layer, a woven mesh layer, a non-woven fabric layer, and an ion exchange layer. The activated carbon layer and ion exchange layer can be constructed by fixing activated carbon particles or ion exchange resin onto a structure such as non-woven fabric, allowing the activated carbon layer and ion exchange layer to bend with the filter body 10.

[0095] The non-woven fabric layer acts as a preliminary filter, intercepting larger impurity particles. The woven mesh layer increases structural strength while also intercepting fine fibers. The activated carbon layer adsorbs odors and organic matter, as well as small molecule pollutants that the filter body cannot intercept. The ion exchange layer removes specific ions from the medium, such as heavy metal ions.

[0096] Therefore, by using functional layers, filters can be adapted to the core needs of more different scenarios, thereby improving the functionality of filters.

[0097] A second aspect of this application provides a filtration system including a bendable filter screen as described above. Other components of the filtration system can utilize existing technology, and therefore will not be described in detail in this embodiment.

[0098] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
