Let's get to know the clean room transfer window!
As a kind of auxiliary equipment for clean room, the transfer window is mainly used for the transfer of small items between clean area and clean area, non-clean area and clean area, in order to reduce the number of door openings in the clean room and minimize the Pollution. Pass windows are widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCD, electronics factories and other places that need air purification.
The transfer window is a kind of auxiliary equipment for clean rooms. It is mainly used for the transfer of small items between clean areas and clean areas, and between clean areas and non-clean areas, in order to reduce the number of door openings in the clean room and contaminate the clean room. Reduced to a minimum. The transmission window is made of stainless steel, which is smooth and smooth. The double doors are interlocked with each other, effectively preventing cross-contamination, equipped with electronic or mechanical interlocking devices, and equipped with ultraviolet germicidal lamps.
The transmission window is divided into three categories: 1. Electronic chain transmission window 2. Mechanical chain transmission window 3. Self-cleaning transmission window
According to the working principle, the transfer window can be divided into air shower transfer window, ordinary transfer window and laminar flow transfer window. Various types of transmission windows can be made according to actual requirements.
Optional accessories: walkie-talkies, germicidal lights and other related functional accessories.
工作 The working table of the short-distance transmission window is made of stainless steel, which is smooth, wear-resistant
无 Long-distance transmission window work surface adopts unpowered roller, easy and convenient to transfer items
⒊The doors on both sides are equipped with mechanical interlocking or electronic interlocking and electronic latching devices to ensure that the doors on both sides cannot be opened at the same time.
4, according to customer needs, customized non-standard size and floor-to-ceiling window.
The wind speed of the air outlet of the ⒌ wind mouth is as high as 20s or more.
⒍Using a partitioned high-efficiency filter, the filtration efficiency is 99.99%, which ensures the purification level.
⒎Using EVA sealing material, high sealing performance.
Fourth, the working principle
⒈Mechanical interlocking device: Internally use mechanical form to achieve interlocking. When one door is opened, the other door cannot be opened, and the other door must be closed before the other door can be opened.
⒉Electronic interlocking device: Internally integrated circuits, electromagnetic locks, control panels, and indicators are used to achieve interlocking. When one door is opened, the other door's opening indicator light is off, telling that the door cannot be opened, and the electromagnetic The locking action realizes interlocking. When the door is closed, the other electromagnetic lock starts to work, and the indicator light is on, indicating that the other door can be opened.
Five, how to use
The transfer window is managed according to the cleanliness level of the higher-level clean zone connected to it. For example, the transfer window connected to the coding room and the filling room should be managed according to the requirements of the filling room. After work, the operator of the clean area is responsible for wiping off the internal surfaces of the transfer window and turning on the UV sterilization lamp for 30 minutes.
1 Materials entering and exiting the clean area must be strictly separated from the flow passages, and enter and exit through the special passage for materials in the production workshop.
2 When the materials enter, the raw materials and auxiliary materials are unpacked or cleaned by the person in charge of the preparation process, and then sent to the workshop's temporary raw materials storage room via the transfer window. Pass the window into the inner compartment. The workshop clerk handles the transfer of materials with the person in charge of the preparation and inner packaging process.
3 When passing through the transfer window, the rules of “one opening and one closing” for the inside and outside doors of the transfer window must be strictly implemented, and the two doors cannot be opened at the same time. Open the outer door and close the door after putting in the material, then open the inner door to take out the material, close the door, and so on.
4 When the material in the clean area is sent out, the material should be transported to the relevant material intermediate station first, and the material should be moved out of the clean area according to the reverse procedure when the material enters.
5 All semi-finished products are transported from the clean area and need to be delivered from the transfer window to the outer temporary storage room and transferred to the outer packaging room through the logistics channel.
6 Materials and wastes that are likely to cause pollution should be transported from their dedicated transfer windows to unclean areas.
7 After the materials are in and out, the sanitation of the scene of the clearing room or the intermediate station and the transfer windows should be timely cleaned, and the internal and external access doors of the transfer windows should be closed to clean and disinfect.
Six, matters needing attention
1. The transfer window is suitable for general transportation. During the transportation, prevent rain and snow, so as not to cause damage and rust.
2. The transfer window should be stored in a warehouse with a temperature of -10 ℃ ~ + 40 ℃, a relative humidity of not more than 80%, and no corrosive gases such as acid and alkali.
3. When unpacking, you should work in a civilized manner without rough and barbarous operations to avoid causing personal injury.
4. After unpacking, please first confirm whether this product is the order product, and then carefully check the contents of the packing list for missing parts, and whether there is any damage to the parts due to transportation.
Seven, operating specifications
擦拭 Wipe the items to be transferred with 0.5% peroxyacetic acid or 5% iodophor.
⒉Open the outside door of the transfer window, quickly place the items to be transferred, disinfect the transfer window with 0.5% peroxyacetic acid spray, and close the outside door of the transfer window.
⒊Turn on the ultraviolet lamp in the transfer window, and the ultraviolet light should be irradiated for at least 15 minutes.
⒋ Notify the experimenter or worker in the barrier system, open the door on the inside of the transfer window, and remove the item.
⒌Close the door inside the transfer window.
