Description

Technical Field

[0001] This utility model relates to the field of air supply system technology, specifically an air supply structure for uniform airflow distribution in a cleanroom of a biological agent building. Background Technology

[0002] The air supply system in the cleanroom of the biopharmaceutical building plays a crucial role in protecting the pharmaceutical production environment. Through primary, medium, and high-efficiency filters, it filters out dust, microorganisms, and other contaminants from the air, ensuring that the air supplied to the cleanroom meets extremely high cleanliness standards. Employing a 100% fresh air or partial return air mode, it precisely controls indoor temperature and humidity, creating a stable and suitable environment for biopharmaceutical production. This effectively guarantees drug quality and safety and is an indispensable core facility for maintaining a clean production environment in the biopharmaceutical field. However, existing air supply systems still have certain problems in use:

[0003] For example, the energy-saving cleanroom air supply device with application number 202120742457.5, which facilitates stable air supply, has the following technical solution: It includes a filter connection port, a filter screen mounting groove fixedly formed on the front surface of the filter connection port, a spring mounting groove fixedly formed on the rear surface inside the filter screen mounting groove, an air filter movably installed inside the filter screen mounting groove, a limiting groove fixedly formed on the front surface of the air filter, and an airflow regulating air outlet fixedly formed on the lower end face of the filter connection port. An regulating air duct is fixedly formed on the lower end face of the airflow regulating air outlet. Adjustable blades are movably installed on both sides of the duct near the lower edge of the port. However, the duct design and outlet layout of the existing air supply system are not reasonable enough, resulting in uneven airflow distribution in the clean room. In some areas, the airflow speed is too fast, which easily stirs up dust, while in other areas the airflow is weak, making it difficult to remove pollutants. This seriously affects the uniformity of cleanliness in the room, increases the risk of microbial contamination, and threatens the quality stability of biological agents. On the other hand, as the core component of air purification, the filter plate needs to be replaced and maintained frequently. The filter plate installation method of the existing system is complicated and difficult to disassemble.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing air supply device. Utility Model Content

[0006] The purpose of this invention is to provide an air supply structure that provides uniform airflow distribution in a cleanroom of a biological agent building, in order to solve the problems of uneven airflow distribution and difficulty in disassembling, cleaning, or replacing filter plates in the aforementioned background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An air supply structure for uniform airflow distribution in a cleanroom of a biological reagent building includes an installation plate installed on the rooftop terrace of the cleanroom. A blower is installed above the installation plate, and an air inlet is provided on the outside of the blower. A main air duct is connected below the air inlet. The main air duct runs through the interior of the ceiling of the cleanroom. A first branch air duct is vertically connected to the far right side of the main air duct, and several second branch air ducts are connected to the front and rear sides of the main air duct. Air outlets are provided on the interior walls of the cleanroom, and each air outlet has an air supply port inside. A filter plate is provided on the left side of the main air duct.

[0009] Preferably, a maintenance plate is provided on the bottom left side of the main air duct, and the top edge of the maintenance plate is engaged with the bottom inside the main air duct.

[0010] Using the above technical solution, the top edge of the maintenance plate on the left bottom side of the main air duct is snapped into the bottom inside the main air duct, which makes it convenient to push the maintenance plate upward and open it quickly when maintenance is needed inside the main air duct, especially near the filter plate, thus facilitating maintenance operations.

[0011] Preferably, a snap-fit ​​groove is fixedly installed on the top left side of the main air duct above the maintenance plate, and the front side of the snap-fit ​​groove is inverted U-shaped.

[0012] By adopting the above technical solution, the inverted U-shaped locking groove on the top left side of the main air duct above the maintenance plate can more firmly lock the filter plate, prevent the filter plate from shaking or shifting inside the main air duct, and ensure the stability of the filtration effect.

[0013] Preferably, a filter plate is snapped into the slot, and a vertical plate is fixedly installed on the bottom surface of the main air duct, with the filter plate and the vertical plate fixed together by bolts.

[0014] Using the above technical solution, the filter plate is snapped into place by a snap-fit ​​groove and fixed to the vertical plate on the bottom of the main air duct with bolts. This installation method not only ensures the firmness of the filter plate installation, but also facilitates the operation by removing the bolts when the filter plate needs to be replaced or cleaned, thus simplifying the maintenance process of the filter plate.

[0015] Preferably, the main air duct, the first branch air duct, and the second branch air duct are all square pipe structures.

[0016] Using the above technical solution, the main air duct, the first branch air duct, and the second branch air duct are all square pipe structures. Compared with other shapes, square pipes are more conducive to the stable delivery of airflow, reduce the turbulence of airflow in the pipe, and help to achieve a more uniform distribution of airflow in the clean room.

[0017] Preferably, an air outlet is provided at the junction of the main air duct and the second branch air duct, and an air outlet is provided at the junction of the second branch air ducts near the interior of the clean room.

[0018] By adopting the above technical solution, air outlets are set at the junction of the main air duct and the second branch air duct, as well as near the interior of the clean room in the second branch air duct. This increases the number and distribution range of air outlets, enabling the airflow to more comprehensively cover all areas of the clean room and further optimizing the uniform distribution of airflow within the clean room.

[0019] Preferably, each of the air outlets is equipped with an air conditioner, and each air conditioner is provided with an air outlet near the air outlet. The air outlet is horn-shaped and is equipped with a fan inside.

[0020] Using the above technical solution, the air conditioner inside the air outlet can regulate the temperature and humidity of the delivered air, meeting the strict requirements of biological agent production for environmental temperature and humidity; the air outlet is horn-shaped and has a fan inside. The horn-shaped design can better guide the airflow diffusion, while the fan enhances the delivery power of the airflow, so that the airflow can be more evenly distributed in the clean room.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the air supply structure of the cleanroom in the biological agent building provides uniform airflow distribution.

[0022] 1. Optimize airflow distribution to ensure the cleanliness of the production environment: By rationally setting the layout of the main air duct, the first branch air duct and the second branch air duct, as well as the position of the air outlet, and in conjunction with the trumpet-shaped air supply outlet and fan, the airflow distribution in the clean room is effectively improved, avoiding abnormal airflow in local areas, reducing dust and pollutant accumulation, maintaining the uniformity of indoor cleanliness, and ensuring the production environment of biological agents.

[0023] 2. Convenient filter plate maintenance and ensure air purification effect: The filter plate adopts a combination of snap-fit ​​and bolt fixing, along with a maintenance plate and snap-fit ​​groove, making the disassembly and installation of the filter plate more convenient. It is easy to clean or replace the filter plate regularly, ensuring its filtration performance and continuously providing high-quality purified air for the clean room. Attached Figure Description

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.

[0031] Please see Figure 1-5 This utility model provides a technical solution:

[0032] An air supply structure for uniform airflow distribution in a cleanroom of a biological reagent building includes a mounting plate 1, which is installed on the roof terrace of the cleanroom. A blower 2 is installed above the mounting plate 1. An air inlet 3 is provided on the outside of the blower 2, and a main air duct 4 is connected below the air inlet 3. The main air duct 4 runs through the ceiling of the cleanroom and is vertically connected to a first branch air duct 5 on the far right side. Several second branch air ducts 6 are connected to the front and rear sides of the main air duct 4. Air outlets 7 are provided on the walls of the cleanroom, and each air outlet 7 has an air supply port 15 inside. A filter plate 11 is provided on the left side of the main air duct 4.

[0033] A maintenance plate 8 is provided on the bottom left side of the main air duct 4, and the top edge of the maintenance plate 8 is snapped into the bottom inside of the main air duct 4. A snap-fit ​​groove 9 is fixedly installed on the top left side of the main air duct 4 above the maintenance plate 8, and the front side of the snap-fit ​​groove 9 is inverted U-shaped. A filter plate 11 is snapped into the snap-fit ​​groove 9. A vertical plate 10 is fixedly installed on the bottom inside of the main air duct 4, and the bottom of the filter plate 11 is fixed to the vertical plate 10 by bolts 12. The maintenance plate 8 on the bottom left side of the main air duct 4 makes it easy to open and maintain and inspect the inside of the main air duct 4, especially the area where the filter plate 11 is located, improving the convenience of maintenance work. The inverted U-shaped snap-fit ​​groove 9 on the top left side of the main air duct 4 can firmly fix the filter plate 11, preventing it from shifting under the impact of airflow and ensuring the reliability of the filtration effect. The filter plate 11 is fixed to the vertical plate 10 by bolts 12, which makes it easy to disassemble and install when the filter plate 11 needs to be replaced or cleaned, reducing maintenance costs and time.

[0034] The main air duct 4, the first branch air duct 5, and the second branch air duct 6 are all square pipe structures. Air outlets 7 are provided at the junction of the main air duct 4 and the second branch air duct 6, and air outlets 7 are also provided near the interior of the clean room in the second branch air duct 6. The square shape of the main air duct 4, the first branch air duct 5, and the second branch air duct 6 is conducive to smooth airflow, reduces energy loss, and improves air supply efficiency. The placement of air outlets 7 at the junction of the main air duct 4 and the second branch air duct 6, and near the interior of the clean room in the second branch air duct 6, increases the air supply coverage, ensuring that all areas of the clean room receive sufficient fresh air and improving the air circulation effect.

[0035] Each air outlet 7 is equipped with an air conditioner 13, and each air conditioner 13 is equipped with an air supply vent 15 near the air outlet 7. The air supply vent 15 is horn-shaped and is equipped with a fan 14. The air conditioner 13 in the air outlet 7 can regulate the air temperature and humidity to meet the strict requirements of biological agent production for environmental temperature and humidity. The horn-shaped air supply vent 15 and the internal fan 14 can make the delivered air more evenly distributed in the clean room and optimize the airflow uniformity.

[0036] Working principle:

[0037] In use, the blower 2 draws in outside air through the air inlet 3. The air enters the main air duct 4, where it is first filtered by the filter plate 11 to remove dust, microorganisms, and other pollutants. The filtered air flows along the main air duct 4, with some air being transported through the rightmost first branch duct 5 and the rest through several second branch ducts 6 on the front and rear sides. Air outlets 7 are located at the junction of the main air duct 4 and the second branch ducts 6, and at the location of the second branch ducts 6 near the interior of the cleanroom, to deliver the air. The air conditioner 13 inside the air outlet 7 regulates the temperature and humidity of the air to meet the requirements of the biological agent production environment. The air outlet 15 is trumpet-shaped, and the internal fan 14 accelerates the delivery of the regulated air and guides the airflow to diffuse evenly to various areas of the clean room. When the filter plate 11 needs maintenance, push the maintenance plate 8 upward to open the bottom left side of the main air duct 4, unscrew the bolt 12 connecting the filter plate 11 to the upright plate 10, and the filter plate 11 can be removed from the snap-fit ​​groove 9 for cleaning or replacement. After maintenance, reinstall it in the original position in reverse order.
