Description
Technical Field
[0001] The present invention belongs to the technical field of air purification devices, and particularly relates to an assembled sterile and dust-free operation room. Background Art
[0002] An assembled sterile and dust-free operation room is a facility specifically designed to provide a sterile and dust-free environment, and is widely used in industries such as pharmaceuticals, biotechnology, and electronic manufacturing. This operation room adopts a modular design, has a very flexible configuration and layout method, and can be quickly built and adjusted according to the needs of different occasions; compared with traditional fixed clean rooms, the assembled operation room has many advantages. The modular design makes the layout of the operation room more flexible, and can be quickly adjusted and reconfigured according to different production and research needs. The construction period of the operation room is short, and it can be quickly put into use, greatly shortening the project implementation period; the maintenance of the assembled operation room is relatively simple, and can better meet the fast-paced needs of modern production and research.
[0003] Patent document CN118750621A discloses a disinfection and purification device for a sterile room, including an installation frame. An isolation door is rotatably connected in the installation frame through a hinge. The installation frame is embedded in a wall body. An isolation mechanism, a disinfection mechanism, and an air circulation mechanism are arranged in the installation frame. The isolation mechanism includes an air pump fixedly connected in the installation frame. The output end of the air pump is fixedly connected with an output pipe. One end of the output pipe far away from the air pump is fixedly connected with a connecting pipe. One end of the connecting pipe far away from the output pipe is fixedly connected with a first shunt pipe. A jet head is fixedly connected in the first shunt pipe. In the present invention, the jet head sprays gas downward to form an air curtain at the inlet and outlet of the installation frame, isolating the gas in two spaces, and effectively preventing bacteria in the external gas from entering. Subsequently, the air circulation mechanism extracts the indoor gas and performs disinfection and purification, thereby achieving the effect of continuously disinfecting and purifying the indoor air.
[0004] Although the above patent document achieves the effect of air disinfection and purification, in order to minimize the direct entry of external gas into the sterile and dust-free operation room as much as possible, a positive pressure wind needs to be maintained in the main working chamber assembly all the time. The prior art usually uses an axial flow fan at the top of the main working chamber assembly, and designs a multiple filtration system or filter screen at the air inlet of the axial flow fan. Since the filtration accuracy of the sterile and dust-free operation room is high, the filter screen is easily blocked in a short time. Moreover, the main working chamber assembly itself is at a high position. If the filter screen is replaced manually, the efficiency is low and there are safety hazards. And the filter screen itself has the danger of shaking at high altitude, which is easy to generate gaps, allowing some air to directly enter the sterile and dust-free operation room without being filtered, failing to meet the requirements of sterility and dust-free, and unable to meet the requirements of safe production of products.

When the jacking assembly 720 is in the working stroke state, at this time the telescopic bag 710 is in a contracted state, and the square boss below the plugging member 730 is separated from the square filter plate 550. A filter baffle 741 is arranged on the square filter support assembly 740 to limit the movement of the square filter plate 550 driven by the electric push rod 510. The rising or falling of the jacking assembly 720 is generally executed by an electric cylinder or an electric push rod and is connected to the PLC control system.
[0062] It should be noted that usually an electromagnetic valve (not shown in the figure) is installed on the straight pipe section of the inclined exhaust pipe 431 close to the re-filtering assembly 700. When the plugging member 730 and the square filter plate 550 below it are clamped, the electromagnetic valve is in an open state. When the plugging member 730 and the square filter plate 550 below it are separated, the electromagnetic valve is in a closed state.
