Description

Technical Field

[0001] This utility model relates to the field of cleanroom technology, and more specifically to a two-layer transfer window for transferring items between different clean areas in a cleanroom. Background Technology

[0002] The transfer of small items between cleanrooms and non-clean areas or between cleanrooms of different levels requires the items to be disinfected. The air velocity of traditional transfer windows is generally 0.36-0.54 m / s, which is not enough to blow away the dust attached to the surface of the items. Utility Model Content

[0003] The purpose of this invention is to provide a two-layer transfer window for transferring items between different clean areas in a cleanroom, in order to solve the technical problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A two-tiered pass-through window for transferring items between different clean areas in a cleanroom, comprising:

[0006] Air shower transfer units arranged side by side; air shower transfer units arranged side by side can work simultaneously;

[0007] The air shower transfer unit includes:

[0008] The frame has a lower part as a transfer compartment and an upper part as an installation compartment.

[0009] A blowing unit is installed in the installation chamber and is used to blow air at a preset wind speed into the transfer chamber;

[0010] A return air unit is installed in the transfer chamber and is used to guide the air in the transfer chamber to the installation chamber.

[0011] In some embodiments, a partition plate is installed in the middle of the frame, which divides the interior of the frame into two independent transfer compartments and an installation compartment.

[0012] In some embodiments, a front access door and a rear access door are respectively installed on the front and rear sides of the installation compartment.

[0013] In some embodiments, the blowing unit is a bottom-mounted FFU, which blows air at a preset wind speed into the transfer chamber.

[0014] In some embodiments, the return air unit includes: a return air perforation plate, the return air perforation plate being disposed on both sides of the transfer chamber, and the return air perforation plate forming a sealed return air cavity with the side walls of the transfer chamber, the top of the return air cavity communicating with the installation chamber, and the return air perforation plate being provided with a plurality of return air holes.

[0015] In some embodiments, the return air perforator plate is provided with a UV lamp on the side away from the return air cavity.

[0016] In some embodiments, the air velocity of the air blown by the blowing unit into the transfer chamber is 18-20 m / s.

[0017] In some embodiments, a differential pressure gauge is provided on the outside of the installation compartment.

[0018] This utility model has the following beneficial effects:

[0019] The technical solution of this application is a specialized device for transferring small items between cleanrooms and non-clean areas, or between clean areas of different levels. It utilizes two independent compartments to transfer items, offering advantages over traditional pass-through windows in terms of material saving and floor space. Traditional construction methods require two pass-through windows to accommodate two compartments on a wall, necessitating two openings in the wall, resulting in a large footprint and greater challenges in subsequent wall sealing. This invention, however, uses a single pass-through window with two independent compartments (upper and lower), requiring only one opening in the wall, thus occupying significantly less space.

[0020] Traditional pass-through windows typically have an air velocity of 0.36-0.54 m / s, which is insufficient to remove dust adhering to the surface of items. However, the air velocity of this new type of air shower can reach 18-20 m / s. The high-speed airflow can remove most of the dust from the surface of items, and the dust is then filtered through a high-efficiency filter to achieve the effect of cleaning the surface of items.

[0030] The following will combine Figure 1-3 This application provides a detailed description of a two-tiered transfer window for transferring items between different clean areas in a cleanroom, as described in the embodiments of this application. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0031] Example 1:

[0032] like Figure 1-3A two-tiered transfer window for transferring items between different clean areas in a cleanroom includes: air shower transfer units arranged side-by-side; the air shower transfer units arranged side-by-side can operate simultaneously; each air shower transfer unit includes: a frame 1, the lower part of which is a transfer chamber, and the upper part of which is an installation chamber; a blowing unit, which is located in the installation chamber and is used to blow air at a preset wind speed into the transfer chamber; the wind speed of the air blown into the transfer area by the blowing unit is 18-20 m / s; and a return air unit, which is located in the transfer chamber and is used to guide the air in the transfer chamber to the installation chamber.

[0033] In some embodiments, a partition plate is installed in the middle of the frame 1, dividing the interior of the frame 1 into two independent transfer compartments and an installation compartment. A front access door 3 and a rear access door 2 are respectively installed on the front and rear sides of the installation compartment. Both the front access door 3 and the rear access door 2 are made of stainless steel and have two pieces of transparent tempered glass on them for easy observation of the items in the transfer area. The doors are controlled by electromagnetic locks. The system is equipped with an interlock between the two access doors to prevent air exchange between the two sides of the transfer compartment.

[0034] The blowing unit is a bottom-mounted FFU5 (including a fan and a high-efficiency filter), which blows air at a preset speed into the transfer chamber. This circulates the air and achieves a self-cleaning effect through high-efficiency filtration.

[0035] In some embodiments, the return air unit includes: a return air perforation plate 4, which is disposed on both sides of the transfer chamber, and the return air perforation plate 4 and the side walls of the transfer chamber form a sealed return air cavity. The top of the return air cavity communicates with the installation chamber, and the return air perforation plate 4 is provided with a plurality of return air holes. An ultraviolet lamp is provided on the side of the return air perforation plate 4 away from the return air cavity.

[0036] When items need to be transferred, the electromagnetic lock is disengaged via the control panel 7, allowing the front access door 3 to be opened. After the items are placed into the transfer chamber through the front access door 3, it is closed. The controller then activates the fan, and air first passes through a high-efficiency filter, then is sprayed at high speed through the air shower nozzles onto the chamber, removing dust from the surface of the items. The dust-laden air enters the return air chamber through the return air vents on the return air plate 4, and is then blown into the installation chamber by the fan to complete the circulation. Simultaneously, during the air shower process, ultraviolet lamps are activated, emitting ultraviolet light to sterilize the surface of the items. A differential pressure gauge 6 is installed on the outside of the installation chamber. By observing the 500Pa differential pressure gauge 6 on the front, the high-efficiency filter needs to be replaced when the specified value is reached. (The differential pressure gauge 6 is used to measure the differential pressure of the high-efficiency filter to determine whether replacement is necessary).

[0037] This transfer window contains two independent control systems, which control the entry and exit of items in the upper and lower air shower transfer units, as well as the sterilization and cleaning of the items. When items need to be transferred, the electromagnetic lock is disengaged via the control panel 7, allowing the passage door to be opened and the items to be sent into the transfer chamber. After the passage door is closed, the controller will automatically start the fan and ultraviolet lamps for cleaning and sterilization. The time can be set by the user. Only after cleaning and sterilization are completed can the other passage door be opened to retrieve the items.

[0038] The above description is only a preferred embodiment of the present utility model and is used to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
