[0034] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] The accompanying drawings show a specific embodiment of an intelligent self-cleaning modular bag filter according to the present invention. Figure 1 It mainly includes a filter body 1, a water inlet 2 is provided on the upper part of the filter body 1, and a water outlet 3 is provided on the lower part. A circle of inwardly protruding support parts 1a is provided on the inner wall of the filter body 1, and the support parts 1a are located below the water inlet 2.

[0037] A filter basket 4 is provided in the filter body 1 , and the filter basket 4 is mounted on the support portion 1 a . A filter bag 5 is sleeved in the filter basket 4 , and the upper portion of the filter bag 5 is stuck between the filter basket 4 and the support portion 1 a .

[0038] A circle of inwardly protruding pressing part 4a is provided on the inner wall of the top of the filter basket 4, and a pressing ring 11 is pressed on the pressing part 4a. A positioning stud 1b is provided on the support part 1a. The pressure ring 11 passes through the positioning stud 1b and is locked and fixed by a locking nut 12.

[0039] Combine Figure 2 、 Figure 3 The outer wall of the filter basket 4 is provided with a plurality of positioning hooks 6. The plurality of positioning hooks 6 are arranged in three layers, with four positioning hooks on each layer. The four positioning hooks 6 on each layer are evenly arranged around the center of the filter basket 4 to ensure that the filter bag 5 is better fixed. The upper portion of the positioning hook 6 is bent inward and extends downward at an angle to prevent it from falling out.

[0040] There is an opening 7 under each positioning hook 6, and a plurality of elastic drawstrings 8 are provided on the outer surface of the filter bag 5. The elastic drawstrings 8 can pass through the opening 7. The elastic drawstrings 8 are provided with connecting holes. By passing the connecting holes into the positioning hooks 6, the elastic drawstrings 8 can be wrapped around the positioning hooks 6 and fixed.

[0041] Combine Figure 4The filter bag 5 includes multiple filter layers arranged in sequence from the inside to the outside. The multiple filter layers are, from the inside to the outside, a hydrophobic nanofiber membrane layer 5a, an electrostatic adsorption non-woven fabric layer 5b, and a biodegradable hydrophilic membrane layer 5c. The edges of each filter layer are bonded together.

[0042] The hydrophobic nanofiber membrane layer 5a is a polytetrafluoroethylene membrane. After entering the filter bag 5 from the water inlet 2, the fluid first passes through this layer, intercepting large particles in the liquid. It then flows through the electrostatically adsorbable nonwoven fabric layer 5b, which captures micron-sized particles. Finally, it passes through the biodegradable hydrophilic membrane layer 5c, made of polylactic acid, which further filters out even smaller impurities. This three-layer filtration process in the filter bag 5 effectively traps impurities of varying sizes within the bag, allowing the clean liquid to be discharged through the water outlet 3, significantly improving filtration accuracy and ensuring optimal filtration results.

[0043] The filter bag 5 can be recycled after use. The hydrophobic nanofiber membrane layer 5a can be regenerated by high-temperature melting, the electrostatic adsorption non-woven fabric layer 5b can be reused by ultrasonic cleaning, and the biodegradable hydrophilic membrane layer 5c can be decomposed after landfill, which is very environmentally friendly.

[0044] A photocatalytic coating 5d is further provided on the innermost filter layer, that is, a photocatalytic coating 5d is provided on the hydrophobic nanofiber membrane layer 5a.

[0045] Further, refer to Figure 1 In this embodiment, a plurality of transparent covers 9 are provided on the outer wall of the filter body 1 and are arranged at intervals around the center of the filter body 1. Preferably, the plurality of transparent covers 9 can be evenly arranged. A UV lamp module 10 is provided on the outer side of each transparent cover 9, and the UV lamp module 10 is detachably connected to the filter body 1.

[0046] Specific, combined Figures 5 to 7 The outer wall of the filter body 1 is provided with an inwardly recessed cavity 1c for mounting a transparent cover 9. The interior of the cavity 1c communicates with the interior of the filter body 1, while the exterior of the cavity 1c communicates with the exterior. The transparent cover 9 seals the interior of the cavity 1c, sealing the interior of the filter body 1. The upper and lower ends of the transparent cover 9 are embedded in the inner wall of the filter body 1 to ensure a good seal. The transparent structure of the transparent cover 9 allows light to pass through.

[0047] The UV lamp module 10 specifically includes a back cover 1001 and a transparent lampshade 1002 sealed to one side of the back cover 1001. A UV lamp tube 1004 is mounted within the interior space between the transparent lampshade 1002 and the back cover 1001 via a bracket 1003. The UV lamp tube 1004 is removable from the bracket 1003 for easy maintenance. The UV lamp tube 1004 extends along the length of the filter basket 4, thereby fully irradiating the filter bag 5. The present invention utilizes a photocatalytic coating 5d coated on the surface of the hydrophobic nanofiber membrane layer 5a of the filter bag 5. This photocatalytic coating, triggered by the UV lamp 1004, decomposes organic matter adhering to the filter bag 5, reducing clogging and extending its service life. When the UV lamp module 10 is installed, the transparent lampshade 1002 conforms to the shape of the cavity 1c and fits snugly within the cavity 1c. The upper and lower ends of the back cover 1001 are respectively provided with connecting plates 1005 , and the filter body 1 is provided with connecting studs 1 d for connecting the connecting plates 1005 . The connecting plates 1005 pass through the connecting studs 1 d and are fixed by connecting nuts 13 .

[0048] When installing the UV lamp module 10, just align the transparent lampshade 1002 with the concave cavity 1c and install it, align the connecting plate 1005 with the connecting stud 1d and install it, and then use the connecting nut 13 to screw on the connecting stud 1d to lock the connecting plate 1005 to fix the UV lamp module 10.

[0049] The back cover 1001 is provided with a detachable opening and closing plate 1006. The length of the opening and closing plate 1006 is longer than the length of the UV lamp 1004, which facilitates the removal of the UV lamp 1004. The lower end of the opening and closing plate 1006 is provided with a positioning ridge 1007. The back cover 1001 is provided with a positioning groove 1001a that cooperates with the positioning ridge 1007. The upper end of the opening and closing plate 1006 is provided with a positioning block 1008. The back cover 1001 is provided with a positioning groove 1001b for the positioning block 1008 to be installed. The length of the positioning groove 1001b is longer than the length of the positioning block 1008, that is, there is a gap between the upper end of the positioning block 1008 and the upper end of the positioning groove 1001b, which facilitates the disassembly and assembly of the opening and closing plate 1006. A spring piece 15 is rotatably mounted on the back cover 1001 on one side of the positioning groove 1001 b via a pin shaft 14 . The spring piece 15 is pressed tightly against the positioning block 1008 , thereby fixing the opening and closing plate 1006 .

[0050] To install the opening and closing plate 1006, first align the positioning protrusion 1007 at its lower end with the positioning slot 1001a at the bottom of the back cover 1001 and insert it. Then, insert the positioning block 1008 at its upper end into the positioning groove 1001b at the top of the back cover 1001 to complete the pre-installation. Then, rotate the spring plate 15 and press it against the positioning block 1008 to secure the opening and closing plate 1006. Opening the opening and closing plate 1006 allows the UV lamp 1004 to be removed for maintenance.

[0051] In addition, the upper and lower portions of the opening and closing plate 1006 are provided with an air inlet port 16 and an air outlet port 17, respectively. The air inlet port 16 is connected to a cooling air source. A temperature sensor 18 is also located within the internal space between the transparent lampshade 1002 and the back cover 1001. This temperature sensor 18 monitors the internal temperature of the UV lamp module 10 in real time. If the temperature is too high, cool air is introduced through the air inlet port 16 for circulation and ventilation, and the heated air is discharged through the air outlet port 17, thereby cooling the internal UV lamp tube 1004 and ensuring its normal operation.

[0052] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications made within the spirit of the main technical solution of the present invention are intended to be included within the scope of protection of the present invention.
