[0002] In industries such as drinking water production, pharmaceuticals, and food processing, cleanrooms are critical areas for ensuring products are free from microbial and particulate contamination. Cleanroom air purification systems typically employ multi-stage filtration, with the high-efficiency particulate filter (HEPA filter) at the end serving as the final barrier to ensure the cleanliness of the supplied air. Traditional cleanroom HEPA filters are usually fixed in the ductwork using bolts or pressure strips, making installation and replacement cumbersome and time-consuming.

[0003] Traditional installation methods are difficult to disassemble. When removing the old filter, the filter plate is prone to vibration, causing accumulated pollutants to scatter and resulting in secondary pollution. Summary of the Invention

[0004] In order to overcome the difficulties in disassembly of traditional installation methods in the background technology, and the problem that the filter plate is prone to vibration when disassembling the old filter, causing the accumulated pollutants to scatter and causing secondary pollution, this utility model provides a quick-disassembly sterile purification and filtration mechanism for clean rooms in drinking water production.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a quick-release aseptic purification and filtration mechanism for cleanrooms used in drinking water production. The mechanism mainly includes a filter housing 1, a limiting frame 2, and a plate filter 3. The filter housing 1 has an air inlet 11 and an air outlet 12 at its two ends. The limiting frame 2 is evenly installed inside the filter housing 1. Through holes 13 for assembling and disassembling the plate filter 3 are opened on the side wall of the filter housing 1 corresponding to the limiting frame 2. The plate filter 3 is inserted into the filter housing 1 through the through holes 13, and is supported and limited on both sides by the limiting frame 2. Lugs 14 are provided at both ends of the through holes 13, and limiting holes 15 are provided on the lugs 14. Elastic pins 4 are installed at the ends of the plate filter 3. The filter 3 and the filter housing 1 are fixedly connected by a flexible pin 4 and a limiting hole 15. A dust removal pipe 5 is provided at the bottom of the air inlet end of the filter housing 1, and a gate valve 6 is provided on the dust removal pipe 5. The plate filter 3 and the filter housing 1 are fixedly connected by a flexible pin 4 and a limiting hole 15 without any tools. The vibration generated during disassembly is small, which effectively avoids a large amount of pollutants from falling and maintains the stability of the cleanroom environment. During disassembly, the valve of the air purification system is closed and the gate valve 6 is opened. The dust removal equipment is used to collect the dust scattered during disassembly through the dust removal pipe 5. The air at the plate filter 3 is reversed by the dust removal equipment, and the scattered dust is sucked away through the dust removal pipe 5 to prevent dust or polluted air from entering the cleanroom and to ensure the cleanliness of the cleanroom environment.

[0020] The lug 14 has a guide notch 16 communicating with the limiting hole 15; the elastic pin 4 includes a sleeve 41, a pin 42, and a tension spring 43. The pin 42 is telescopically inserted into the sleeve 41, and the two ends of the tension spring 43 are respectively fixed to the bottom of the pin 42 and the bottom of the sleeve 41. The pin 42 has a guide section 44 that can enter the limiting hole 15 through the guide notch 16 and a limiting section 45 that matches the limiting hole 15; the top of the pin 42 has a pull ring 46 for easy operation; when installing the plate filter 3, when the plate filter 3 is inserted to a certain position, pull the pull ring 46 to extend the pin 42, so that the guide section 44 is aligned with the guide notch 16, and then... Continue pushing the plate filter 3, the guide section 44 slides within the guide notch 16. When the guide section 44 is within the limiting hole 15, release the pull ring 46. Under the pulling force of the pull spring 43, the pin 42 retracts, and the limiting section 45 is embedded in the limiting hole 15. Because the size of the limiting section 45 is larger than the guide notch 16, it can form a stable limit. When disassembling the plate filter 3, pull the pull ring 46 to extend the pin 42, so that the guide section 44 is within the limiting hole 15. Pull the disassembled plate filter 3 to pull it out. The entire disassembly process is relatively smooth, effectively reducing the vibration of the disassembled plate filter 3 and effectively preventing dust from falling off the disassembled plate filter 3.

[0021] The plate filter 3 includes a mounting frame 31 and a filter plate 32. The filter plate 32 is installed inside the mounting frame 31. Inflatable sealing rings 33 are embedded on both sides of the mounting frame 31. The mounting frame 31 is sealed to the limiting frame 2 through the inflatable sealing rings 33. An air inlet 34 connected to the inflatable sealing rings 33 is installed at the outer end of the mounting frame 31. An easy-to-operate handle 35 is provided at the outer end of the mounting frame 31. The mounting frame 31 is sealed to the limiting frame 2 through the inflatable sealing rings 33. Before disassembly, the air in the inflatable sealing rings 33 is discharged, which can effectively reduce the frictional resistance during the pushing and pulling process of the plate filter 3, ensure that the pushing and pulling of the plate filter 3 is smoother, and effectively prevent dust from falling off the disassembled plate filter 3.

[0022] The dust removal pipe 5 is equipped with an exhaust fan 61. The end of the dust removal pipe 5 is fitted with a dust removal bag or extends to the outside. With the exhaust fan 61, there is no need to use dust removal equipment. The dust can be collected into the dust removal bag or discharged to the outside by starting the exhaust fan 61.

[0023] Work process: When installing the plate filter 3, once it is inserted to a certain position, pull the pull ring 46 to extend the pin 42, aligning the guide section 44 with the guide notch 16. Continue pushing the plate filter 3, allowing the guide section 44 to slide within the guide notch 16. When the guide section 44 is within the limiting hole 15, release the pull ring 46. Under the tension of the pull spring 43, the pin 42 retracts, and the limiting section 45 embeds into the limiting hole 15. Because the size of the limiting section 45 is larger than the guide notch 16, it forms a stable limit. When disassembling the plate filter 3, pull the pull ring 46 to extend the pin 42, positioning the guide section 44 within the limiting hole 15. Pulling the disassembled plate filter 3 will then remove it. The entire disassembly process is relatively smooth, effectively reducing vibration and preventing dust from scattering from the disassembled plate filter 3. The mounting frame 31 is sealed to the limiting frame 2 via an inflatable sealing ring 33. Before disassembly... Expelling the air from the inflatable sealing ring 33 effectively reduces the frictional resistance during the pushing and pulling of the plate filter 3, ensuring smoother pushing and pulling and effectively preventing dust from falling off the disassembled plate filter 3. With the exhaust fan 61, there is no need to use dust removal equipment; simply starting the exhaust fan 61 will collect the scattered dust into the dust collection bag or discharge it outdoors. The plate filter 3 and the filter housing 1 are fixed together by the elastic pin 4 and the limiting hole 15, requiring no tools. The vibration generated during disassembly is small, effectively preventing a large amount of pollutants from falling off and maintaining the stability of the cleanroom environment. During disassembly, the valves of the air purification system are closed, and the gate valve 6 is opened. The dust removal equipment collects the dust scattered during disassembly through the dust removal pipe 5. The dust removal equipment reverses the airflow at the plate filter 3, sucking away the scattered dust through the dust removal pipe 5, preventing dust or polluted air from entering the cleanroom and ensuring the cleanliness of the cleanroom environment.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
