Description

Technical Field

[0001] This utility model relates to the field of filters, specifically to a high-efficiency air filter for cleanrooms. Background Technology

[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. To achieve a cleanliness level, a comprehensive set of measures is required, including process layout, building plan, building structure, building decoration, personnel and material purification, air purification measures, and maintenance management. Among these, air purification measures are the fundamental guarantee for achieving a cleanliness level, and air purification is usually achieved through high-efficiency air filters.

[0003] While conventional high-efficiency air filters can achieve air filtration, their filter plates are inconvenient to replace, and the high-efficiency air filter must be taken out of service during the replacement process, resulting in a lack of continuous air purification. Further improvements are needed.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Please refer to the appendix. Figures 1-4 The present invention provides a high-efficiency air filter for cleanrooms, including a filter housing 1, a partition 2 fixed inside the filter housing 1, two sets of air filtration components fixed inside the filter housing 1, a dual-channel air intake component fixedly connected to the rear end of the filter housing 1, the two sets of air filtration components corresponding to the dual-channel air intake component, and a dustproof component fixed to the front end of the filter housing 1.

[0021] The dual-channel air intake assembly includes two air collection hoods 3, which are symmetrically and fixedly connected to the rear end of the filter housing 1. A partition 2 is located between the two air collection hoods 3. A right-angle bend 4 is fixedly connected to the rear end of each air collection hood 3. A shut-off valve 5 is fixedly connected to the body of each of the two right-angle bends 4, which can be used to switch the dual-channel air intake. A three-way pipe 6 is fixedly connected to the rear end of each of the two right-angle bends 4. An air intake pipe 7 is fixedly connected to the rear end of the three-way pipe 6. That is, outside air can be filtered inside the filter housing 1 and then enter the clean room through the air collection hoods 3, right-angle bends 4, three-way pipe 6 and air intake pipe 7.

[0022] Each air filter assembly includes several filter plates 8. The filter plates 8 of the same group are inserted into the filter housing 1 from front to back. Two sets of filter plates 8 are located in front of two air collection hoods 3, and are symmetrically arranged on both sides of the partition 2. HEPA high-efficiency filters 9 are fixed inside each filter plate 8 for efficient air filtration. Several insertion sockets 10 are symmetrically fixed on both sides of the partition 2. A first rubber sealing gasket 11 is fixed inside each insertion socket 10. The ends of the filter plates 8 located inside the filter housing 1 are inserted into the insertion sockets 10, and the filters... One end of the filter plate 8 located inside the filter housing 1 abuts against the first rubber sealing gasket 11. Several second rubber sealing gaskets 12 are symmetrically fixed on both sides of the filter housing 1. The surface of the filter plate 8 abuts against the surface of the second rubber sealing gasket 12. An end plate 13 is fixed to one end of the filter plate 8 located in the filter housing 1. A handle 14 is fixed to the surface of the end plate 13. Specifically, under the joint sealing action of the first rubber sealing gasket 11 and the second rubber sealing gasket 12, the sealing performance of the filter plate 8 when inserted into the filter housing 1 can be effectively guaranteed, which is beneficial to the air filtration effect.

[0023] Several connecting rods 15 and several baffles 16 are symmetrically fixed on both sides of the filter housing 1. The connecting rods 15 are located on one side of several end plates 13. Each connecting rod 15 is fixed with a limiting plate 17. One end of the baffle 16 has a through hole 18 through which the connecting rod 15 passes. A nut 19 is threaded onto the surface of the connecting rod 15. One end of the baffle 16 abuts against the surface of the limiting plate 17, and the other end of the baffle 16 abuts against the surface of the end plate 13. Specifically, under the blocking action of the baffle 16, the corresponding filter plate 8 can be stably and sealed in the filter housing 1. The operator only needs to loosen or tighten the nut 19 to control the rotation of the baffle 16, which makes it easy to disassemble the filter plate 8 and convenient to use.

[0024] The dustproof component includes two fixed frames 20, which are symmetrically fixed on both sides of the front end of the filter housing 1. The partition 2 is located between the two fixed frames 20. Dustproof nets 21 are fixed inside the fixed frames 20. Specifically, under the dustproof function of the dustproof nets 21, dust and other impurities in the air can be effectively pre-filtered, thereby effectively reducing the replacement frequency of the filter plate 8.

[0025] The usage process of this utility model is as follows: When in use, the operator keeps the shut-off valve 5 on the right-angle bend 4 open and the shut-off valve 5 on the other right-angle bend 4 closed, so that the outside air is pre-filtered by the dustproof net 21 and then highly filtered by the HEPA high-efficiency filter 9 on the filter plate 8. The filtered clean gas enters the clean room through the corresponding air collection hood 3, right-angle bend 4, three-way pipe 6 and air inlet pipe 7, thus having the function of highly filtering the air entering the clean room.

[0026] When the HEPA filter 9 on the filter plate 8 in one channel becomes clogged and needs to be replaced, the operator closes the shut-off valve 5 in that channel and opens the shut-off valve 5 in another channel. The air is then continuously filtered through the HEPA filter 9 on the filter plate 8 in the other channel without interrupting use. When replacing the filter plate, the operator can loosen the nut 19, then rotate the baffle 16 and pull out the corresponding filter plate 8 using the handle 14. The new filter plate 8 is then reinserted into the filter housing 1 and secured by the baffle 16. This allows for convenient disassembly and replacement of the filter plate 8. The dual-channel air intake system enables alternating air filtration. When the filter plate 8 in one channel is being disassembled or replaced, the air can be continuously purified through the filter plate 8 in the other channel, thus ensuring continuous filtration of the cleanroom air.

[0027] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
