Description

Technical Field

[0001] This utility model relates to the field of air shower technology, and in particular to an air shower-type cleanroom airflow circulation structure. Background Technology

[0002] Air showers are an essential passageway for entering cleanrooms, reducing contamination from people entering and exiting. They are versatile local purification devices installed between cleanrooms and non-cleanrooms. When people or goods need to enter the clean area, they must pass through the air shower, where the clean air removed dust carried by the people and goods, effectively blocking or reducing dust sources from entering the clean area.

[0003] Existing air showers generally use a direct airflow method, creating a vertical turbulent flow field. However, their airflow organization has several defects: First, it easily creates a large number of dead air zones, especially in areas such as the armpits, back, waist, and legs where cleaning is inadequate. Second, the air velocity distribution is uneven, with some areas experiencing excessively high air velocities that cause discomfort, while other locations have insufficient air pressure, making it difficult to effectively remove dust. The overall airflow coverage is discontinuous and directional, resulting in an upper limit to the particulate matter removal efficiency and making it difficult to achieve efficient and uniform removal of pollutants from the human body surface.

[0004] To address the aforementioned problems, this utility model proposes an airflow circulation structure for an air shower-type cleanroom. Utility Model Content

[0017] Please see Figure 1-3 This utility model provides a technical solution: an air shower type cleanroom airflow circulation structure, including an air shower 1, with automatic doors 2 slidably installed on both the front and rear sides of the air shower 1.

[0018] The air shower chamber 1 has symmetrical guide grooves 3 on both sides inside. Two sets of annular sprayers 4 are installed in the guide grooves 3 on both sides. The annular sprayers 4 include annular pipes 11 and air outlet pipes 12. Connecting plates 13 are fixedly installed on both sides of the annular pipes 11. The connecting plates 13 slide in the guide grooves 3. Multiple air outlet pipes 12 are fixedly installed in a spiral shape on the bottom side of the annular pipes 11. The air outlet pipes 12 are connected to the interior of the annular pipes 11. The annular pipes 11 and the air outlet of the first fan 5 are connected through air pipes 14.

[0019] The top surface and the bottom surface of the air shower 1 are provided with mounting grooves 7 at the positions of the annular sprayers 4. The first fan 5 is fixedly installed in the top mounting groove 7. The top spray head 6 is fixedly installed on the top surface of the air shower 1. Both the annular sprayer 4 and the top spray head 6 are connected to the air outlet of the first fan 5. The second fan 8 is fixedly installed in the bottom mounting groove 7.

[0020] The top of each of the two mounting slots 7 is fitted with a filter assembly 9; the filter assembly 9 includes an air inlet plate 16 and a filter plate 17, the lower end face of the air inlet plate 16 abuts against the upper end face of the filter plate 17, and a boss is fixedly installed on the inner wall of each mounting slot 7, the bottom end of the filter plate 17 abuts against the upper end face of the boss, and the air inlet plate 16, the filter plate 17 and the inner wall of the mounting slot 7 are in transition fit.

[0021] In this embodiment of the invention: air ducts 10 are fixedly installed on both sides of the air shower 1. The bottom end of the air duct 10 is connected to the air outlet of the second fan 8, and the top end of the air duct 10 is connected to the air inlet of the first fan 5. This achieves airflow circulation, improves energy efficiency, and maintains stable internal pressure in the clean room.

[0022] In this embodiment of the invention: hydraulic push rods 15 are fixedly installed on both the upper and lower sides of the guide groove 3, and the telescopic ends of the hydraulic push rods 15 are fixedly connected to the corresponding connecting plates 13. This enables flexible adjustment of the height of the annular sprayer, adapting to users of different heights and optimizing the spraying effect.

[0023] Specifically, an air guide plate 18 is fixedly installed on the inner top surface of the air shower room 1, and multiple top spray nozzles 6 are evenly fixedly installed on the lower end face of the air guide plate 18. An air guide channel is opened inside the air guide plate 18, and the air pipe 14 and the top spray nozzles 6 are all connected to the air guide channel.

[0024] Working principle: In use, after personnel enter the air shower 1, the automatic door 2 closes, and the hydraulic push rod 15 is activated to push the connecting plate 13 to move up and down along the guide groove 3: the upper hydraulic push rod 15 extends, and the lower hydraulic push rod 15 retracts, driving the two sets of annular sprayers 4 to move downwards synchronously until they are positioned at appropriate heights above the personnel's shoulders and below their waists, respectively. Then, the first fan 5 starts, and the intake air is purified by the filter assembly 9. The clean airflow is delivered to the top spray head 6 through the air guide channel of the air guide plate 18, and simultaneously delivered to the annular pipe 11 and multiple spirally distributed air outlet pipes 12 through the air pipe 14. The angled nozzles of the air outlet pipes 12 generate a high-speed spiral airflow, which completely wraps around the personnel's entire body in a top-down motion. Through the shearing action and centrifugal effect, it achieves efficient removal of contaminants from the surface of clothing.

[0025] The airflow carrying pollutants continues to move downwards and is drawn in by the second fan 8 in the bottom mounting slot 7. It undergoes initial filtration and purification through the bottom filter assembly 9, and is then transported back to the top through the air duct 10, where it undergoes secondary filtration again through the top filter assembly 9. This forms a continuous, closed airflow circulation system, achieving efficient reuse of clean air and thorough removal of pollutants.

[0026] It should be noted that the devices in this application, such as the automatic door 2 and the first fan 5, are all common devices on the market. They can be selected according to the specific needs when used. The circuit connection relationship of each device is a simple series and parallel connection circuit.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
