[0018] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.
[0019] As shown in Figures 1, 2 and 3, the sterile gas input mechanism in the sterile isolation chamber includes: a sterile chamber 1 for connecting to the sterile isolation chamber, and one end of the bottom of the sterile chamber 1 is a connection end 14 connected to the sterile isolation chamber. The function of the sterile isolation chamber is to seal the filling equipment and ensure that the interior is sterile. The top of the sterile chamber 1 is sealed and connected to a high-efficiency air filter 2, and the top of the high-efficiency air filter 2 is sealed and connected to an air input box 3, and an air input power mechanism is provided in the air input box 3, and the air input power mechanism is a fan 31. The top of the air input box 3 is sealed and connected to a primary filter box 4 with an air inlet hole, and an air primary filter 41 is provided in the primary filter box 4. In this embodiment, in order to improve the cleanliness of the air, the high-efficiency air filter 2 is stacked in two levels, upper and lower.
[0020] The sterile chamber 1 is divided, from bottom to top, into a sterile buffer zone 11, a sterile diffuser zone 12, and a sterile isolation zone 13. The sterile buffer zone 11 is equipped with a cleaning device 101 for spraying and cleaning the interior of the sterile buffer zone 11. The sterile diffuser zone 12 is equipped with a diffuser assembly that prevents liquid from entering the sterile isolation zone and diverts gas flow. The sterile isolation zone 13 is equipped with a sterilization device capable of ultraviolet sterilization. In this embodiment, the sterilization device is a magnetic UV lamp 103. Two magnetic UV lamps 103 are provided, and they can operate alternately.
[0021] As shown in FIG3 , the structure of the diffuser assembly within the sterile diffuser zone 12 includes: a fixed orifice plate 5 having a plurality of diffuser holes 501 evenly distributed thereon, each having a diameter of 1.5 to 2.5 mm, and a height of 1 to 2 times the diameter of each diffuser hole 51. Setting the aperture of the diffuser holes 51 to 1.5 to 2.5 mm not only achieves airflow distribution but also effectively prevents liquid below the orifice plate 5 from entering the sterile isolation zone 13. Preferably, the height of the diffuser holes 51 is appropriately increased, such as by setting the height of the diffuser holes 51 to twice the aperture of the diffuser holes 51, to more effectively prevent liquid below the orifice plate 5 from passing through the orifice plate and entering the sterile isolation zone 13.
[0022] In this embodiment, tie screws 7 are provided on both sides of the top of the sterile chamber 1. Connecting plates 32 with connection holes are fixedly provided on the outer walls of both sides of the air input box 3. The HEPA filter 2 and the air input box 3 are located on the inner sides of the tie screws 7. The tie screws 7 extend into the connection holes of the connecting plates 32 on the corresponding air input box 3. The tie screws 7 are fastened to the connecting plates 32 via bolts. This connection structure is very convenient for installation, greatly facilitating the replacement of the HEPA filter 2.
[0023] In order to quickly discharge the liquid during cleaning, the bottom plate 16 of the sterile bin 1 is tilted downward in this embodiment. In addition, a sterile bin window 15 made of transparent material for observing the inside of the sterile bin 1 is provided on one side of the sterile bin 1.
[0024] The operating principle is as follows: During aseptic filling production, air is filtered by the primary filter 41 in the primary filter housing 4 under the action of the fan 31. It is then further filtered by the two-stage high-efficiency air filter 2 to form clean air. The clean air then passes through the sterile isolation area 13, the sterile bulk area 12, and the sterile buffer area 11, and then enters the sterile isolation chamber through the connection end 14 of the sterile chamber 1.
[0025] When the aseptic filling equipment is being cleaned and sterilized, the cleaning device 101 sprays and cleans the interior of the sterile buffer zone 11 with a sterilizing spray. The arrangement of the orifice plate 5 in the sterile bulk flow area 12 can effectively prevent liquid from entering the sterile isolation area 13 and soaking the air high efficiency filter 2 when the cleaning device 101 sprays and cleans the interior of the sterile buffer zone 11. The bulk flow components in the sterile bulk flow area 12 not only play a good role in gas distribution, but also play a role in preventing liquid from entering the sterile isolation area 13 upward, thereby effectively protecting the air high efficiency filter 2. In addition, the structure of the orifice plate 5 is very simple, which can effectively reduce the overall production cost of the equipment.
[0026] At the same time, the magnetic ultraviolet lamp 103 in the sterile isolation area 13 is turned on, and the ultraviolet rays generated by the magnetic ultraviolet lamp 103 effectively sterilize the interior of the sterile isolation area 13. The two magnetic ultraviolet lamps 103 can work alternately as needed to ensure that the interior of the sterile isolation area 13 is effectively completed. In the present application, the magnetic ultraviolet lamp 103 is provided, which can effectively avoid the technical problem that the sterile isolation area 13 becomes a sterilization dead corner. Since the sterilizing liquid cannot enter the sterile isolation area 13 due to the blockage of the bulk component during spray cleaning, the provision of the magnetic ultraviolet lamp 103 effectively solves this technical problem, which can also effectively ensure the sterility of the gas entering the sterile isolation chamber, thereby effectively extending the sterility maintenance time of the entire aseptic filling equipment.
[0027] It can be seen that the advantages of the utility model are: simple structure, no sanitary dead corners, can effectively ensure the sterility of the gas delivered to the inside of the sterile isolation chamber, thereby effectively ensuring the sterility of the inside of the sterile isolation chamber, and can effectively extend the sterility retention time of the entire aseptic filling equipment, thereby greatly improving the quality of the products produced by aseptic filling.
