Description

Technical Field

[0001] The utility model relates to the technical field of clean air duct installation, in particular to a connection structure of a return air wall plate and a clean air duct. Background Art

[0002] With the acceleration of urbanization, the number of buildings is increasing, and people have higher and higher requirements for the comfort, energy saving and functionality of buildings. Especially in places with cleanliness requirements such as laboratories, hospitals, GMP workshops, etc., there are functions such as supply and return air to ensure indoor cleanliness and pressure difference. Therefore, during the installation process, it is necessary to consider many factors such as the selection of building materials and installation methods. On the basis of keeping the return air volume unchanged, the connection form of each component is optimized to ensure that it is not affected by equipment vibration during use and reduce the risk of air leakage.

[0003] The traditional method for installing return air panels and clean air ducts is to wrap the clean air duct around the outside of the return air panel. This installation method is extremely inconvenient for subsequent disassembly and maintenance of the return air panel, requiring the clean air duct to be removed as well. This involves many steps and is costly, making it difficult to perform subsequent maintenance. Furthermore, the lack of sealing strips at the interface creates the risk of air leakage over time and fails to maintain indoor pressure differentials. Therefore, a connection structure between the return air panel and the clean air duct is needed to address the above technical issues. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure between a return air panel and a clean air duct, wherein the L-shaped bend of the clean air duct is extended into the hollow return air duct of the return air panel. When cleaning and inspecting the return air duct, the return air panel only needs to be disassembled, and the clean air duct does not need to be disassembled first. This effectively reduces the disassembly process for subsequent cleaning and inspection, and is low in cost. At the same time, by adding sealing strips A and B, a double-layer seal is formed to ensure the sealing of the connection between the clean air duct and the return air panel. At the same time, sealing strip B has a vibration-reducing effect, which increases the cushioning of the connection between the clean air duct and the return air panel during return air operation.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a return air wall panel and clean air duct connection structure, comprising a clean air duct and multiple return air wall panels; the clean air duct is fixed to the ceiling through a hanging assembly; wherein: the hollow space between the return air wall panels forms a return air duct; the clean air duct is provided with multiple L-shaped bending parts; the clean air duct is connected with the return air duct through the L-shaped bending parts; the tail of the clean air duct entering the return air duct is provided with a G-shaped mounting part; a sealing strip A is installed on the G-shaped mounting part; a strip keel is provided on the top of the return air wall panel; a sealing strip B is fixed on the strip keel; the sealing strip B and the clean air duct are connected into a whole by glue.

[0006] As a further improvement to the technical solution of the present invention, the clean air duct is wrapped with B1 grade thermal insulation cotton.

[0007] As a further improvement to the technical solution of the present invention, a color steel plate ceiling is provided at the top between the return air wall panels; the B1 grade thermal insulation cotton abuts against the color steel plate ceiling.

[0008] As a further improvement to the technical solution of the present invention, the hanging assembly includes a hot-dip galvanized hanger rod and a gasket; the clean air duct is fixed to the ceiling through the hot-dip galvanized hanger rod and the gasket.

[0009] As a further improvement to the technical solution of the present invention, a return air box is provided on the L-shaped bending portion.

[0010] As a further improvement to the technical solution of the present invention, the clean air duct is a galvanized air duct.

[0011] The utility model has the following beneficial effects:

[0012] The utility model sets the L-shaped bending part of the clean air duct in the hollow return air duct of the return air wall panel. When cleaning and repairing, it is only necessary to disassemble the return air wall panel without first disassembling the clean air duct, which effectively reduces the disassembly process for subsequent cleaning and repair and reduces labor costs. At the same time, by adding sealing strips A and B, a double-layer seal is formed to ensure the sealing of the connection between the clean air duct and the return air wall panel. At the same time, the sealing strip B has a vibration reduction effect, which increases the buffering of the connection between the clean air duct and the return air wall panel during the return air operation. The utility model is convenient for subsequent disassembly, cleaning, inspection, and maintenance. There is no need to disassemble the clean air duct and then the return air wall panel, which can better protect the finished product. The entire return air wall panel and clean air duct of the utility model are assembled, and are flexible and convenient to install and disassemble, which is conducive to promotion and use.
