Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, specifically a material transfer buffer room in a cleanroom to prevent cross-contamination. Background Technology

[0002] A cleanroom, also known as a dust-free room or cleanroom, is a specially designed room that eliminates airborne particles, harmful gases, bacteria, and other contaminants within a defined space. It controls temperature, humidity, cleanliness, pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within specific requirements. Material transfer buffer rooms, on the other hand, are transitional spaces between clean and non-clean areas, or between areas of different cleanliness levels. They are primarily used for material transfer to prevent cross-contamination and ensure the clean area's environment is unaffected by external pollution or interference between areas of different cleanliness levels. They typically have two or more doors connecting different areas, and these doors cannot be opened simultaneously, creating an "airlock" effect. The internal space is generally small but rationally planned, with shelves or platforms for storing materials. Some buffer rooms are also equipped with pass-through windows with interlocking devices, preventing both doors from opening simultaneously. This facilitates the rapid transfer of small items, improving efficiency while preventing excessive airflow. However, existing material transfer buffer rooms, when in use, make it inconvenient to exhaust air from the transfer area, hindering air circulation and making it difficult to retrieve materials from within.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4This utility model provides a technical solution: a material transfer buffer room in a clean room to prevent cross-contamination, including a transfer box 10, a first cover 20, a second cover 30, a water tank 40, a water pump 401, a pipe 402, an atomizing nozzle 403, an ultraviolet lamp box 404, a wind box 50, a motor 501, a rotating shaft 502, a fan 503, a placement plate 504, a filter screen 505, a reducer 506, an infrared sensor 507, an exhaust pipe 508, an air inlet pipe 509, and a solenoid valve 5010;

[0029] This material transfer buffer room is designed for easy venting, and the specific implementation method is as follows:

[0030] The transfer box 10 has an internal rotating structure, which includes: a motor 501 installed inside the air box 50, with a rotating shaft 502 connected to the output shaft of the motor 501; a fan 503 connected to the surface of the rotating shaft 502; a filter 505 embedded in the bottom surface of the air box 50; a reducer 506 installed at the bottom of the filter 505; the output shaft of the rotating shaft 502 passing through the filter 505 and connected to the reducer 506; and a placement plate 504 connected to the end of the output shaft of the reducer 506. An infrared sensor is installed on one side of the cover 30. The linear sensor 507 and the air box 50 are connected to an exhaust pipe 508. An air inlet pipe 509 is installed on the surface of the cover 30, and a solenoid valve 5010 is installed inside the air inlet pipe 509. The rotating shaft 502 is rotatably connected to the filter screen 505, and the fan 503 is positioned correspondingly to the filter screen 505. The bottom of the placement plate 504 is in contact with the bottom surface of the transfer box 10, and the transfer box 10 is rotatably connected to the placement plate 504. The placement plate 504 is set as a cylindrical structure, and the atomizing nozzles 403 are symmetrically arranged on both sides of the placement plate 504.

[0031] During installation, place cover 20 inside the cleanroom and cover 20 outside the cleanroom. Open cover 20 and allow it to rotate on the surface of transfer box 10. This allows materials to be placed on the surface of placement plate 504. Then close cover 20 and disinfect the materials using atomizing nozzle 403. Simultaneously, start solenoid valve 5010 and motor 501. Motor 501 drives rotating shaft 502 to rotate, which in turn drives surface fan 503 to rotate on the surface of filter screen 505. This allows humid gas inside transfer box 10 to enter air box 50. The air box 50 then transmits the gas to exhaust pipe 508, which discharges the gas. Exhaust pipe 508 is equipped with a one-way valve to prevent gas backflow. At the same time, solenoid valve 5010 opens, allowing gas inside the cleanroom to enter transfer box 10 through air inlet pipe 509.

[0032] Simultaneously, the rotating shaft 502 transmits power to the reducer 506, causing the reducer 506 to drive the placement plate 504 to rotate. At the same time, the rotation speed of the placement plate 504 relative to the rotating shaft 502 decreases, causing the placement plate 504 to rotate inside the transfer box 10. This rotation of the placement plate 504 causes the surface material to rotate, allowing the atomizing nozzle 403 to spray it in all directions. After the gas is discharged, the motor 501 is turned off, and the solenoid valve 5010 is also turned off. At the same time, the reducer 506 reduces the rotation speed of the placement plate 504. At this time, the infrared sensor 507 senses the position of the material, which sends an electrical signal to the control device to keep the material positioned on one side of the cover 30. Then, the cover 30 is opened, allowing the material to be easily removed.

[0033] This material transfer buffer room can disinfect materials. The specific implementation method is as follows:

[0034] The surface of the transfer box 10 is symmetrically and rotatably equipped with a first cover 20 and a second cover 30. An air box 50 is installed inside the transfer box 10. A water tank 40 is symmetrically installed on the surface of the transfer box 10. A water pump 401 is installed on the surface of the water tank 40. A pipe 402 is installed on the surface of the water pump 401. The end of the pipe 402 is inserted into the transfer box 10 and connected to an atomizing nozzle 403. An ultraviolet lamp box 404 is symmetrically installed on the inner wall of the transfer box 10. The transfer box 10 is designed as a hollow structure. The first cover 20 and the second cover 30 are symmetrically arranged on both sides of the opening of the transfer box 10. An air outlet is provided on the top of the transfer box 10. The atomizing nozzles 403 are symmetrically arranged on both sides of the transfer box 10, and the positions of the atomizing nozzles 403 and the ultraviolet lamp boxes 404 are staggered.

[0035] After the material is placed on the surface of the placement plate 504, the water pump 401 is started. The water pump 401 draws disinfectant water from the water tank 40 and transfers the disinfectant water to the pipe 402. The disinfectant water passes through the pipe 402 and the atomizing nozzle 403, and is sprayed out through the atomizing nozzle 403, so that the disinfectant water is sprayed on the surface of the material. After the disinfectant water cleaning is completed, the ultraviolet lamp box 404 is turned on to irradiate the material and disinfect it. Then the cover 30 is opened.

[0036] Working principle: When using the material transfer buffer room in this cleanroom to prevent cross-contamination, it is equipped with atomizing nozzles 403, ultraviolet lamp box 404 and air box 50 to disinfect materials. It is also equipped with infrared sensor 507, exhaust pipe 508, air inlet pipe 509 and solenoid valve 5010 to facilitate exhaust and increase the overall practicality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
