Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal fan components, in particular to a sealing composite plate for a double-duct fan. Background Art

[0002] Centrifugal fans usually adopt a single air duct structure during production. In some demanding and complex application environments, a dual air duct structure will be required. The existing dual air duct structure components are assembled and combined using separate channel pipes. The space occupied during production is relatively large, and the position stability between each other when assembled is relatively poor. In order to improve the safety of the use of dual-duct centrifugal fans, the company has designed a dual-duct integrated centrifugal fan. By integrating the two air ducts together and arranging them in a staggered distribution manner, the stability of the air duct and the overall occupied volume can be effectively reduced. The existing air duct components cannot meet the coordination requirements during use, and new air duct components need to be designed to meet the coordination connection during installation.

[0019] like Figures 1 to 7As shown, a dual-duct fan sealing assembly plate includes a main body mating connecting plate 1 made of PVC material. The right side of the main body mating connecting plate 1 is provided with an installation assembly connecting plate 2. Through this structure, the assembly plate is assembled and matched as a whole, enabling the assembly plate to be sealed and matched with the dual-duct assembly. The lower end of the main body mating connecting plate 1 is provided with a first duct mating groove 3 opening to the left, near the rear side, and the upper end of the main body mating connecting plate 1 is provided with a second duct mating groove 4 opening to the left, which are respectively mated and connected with different air ducts. The upper end surface of the first duct mating groove 3 and the lower end surface of the second duct mating groove 4 are respectively provided with a conical first duct acceleration groove 5 and a second duct acceleration groove 6, which ensure better accelerated circulation inside the air duct during use. The lower end of the installation assembly connecting plate 2 is provided with an installation locking mating boss 7, which is used for locking connection. The upper end of the installation assembly connecting plate 2 is provided with a combination sealing limit boss 8 to ensure the mating sealing and stability during assembly. The upper and lower positions of the assembly connecting plate 2 are composed of air duct matching mounting surfaces of different heights, so that when it is installed, it takes up less space and fits more tightly when it is installed with the air duct structure at different positions. When in use, it can be combined and connected with the channel position of the dual-duct fan, and can play a role in sealing and covering the connection and matching. The main ventilation position of the assembly connecting plate 2 is provided with an air duct acceleration slot, which can ensure a higher wind speed during use. During installation, it is installed and matched by a locking method, which can ensure that the operation during installation is more convenient. During installation, it can meet the installation requirements of the integrated dual-duct assembly when sealing. During later maintenance and cleaning, the assembly plate can be disassembled separately, making maintenance more convenient.

[0020] Preferably, the first air duct acceleration groove 5 and the second air duct acceleration groove 6 are both composed of two matching grooves with arc-shaped cross-sections, which have a better acceleration effect during use.

[0021] Preferably, the size of the outer position of the installation snap-fitting boss 7 is larger than the size of the position close to the side of the installation combination connecting plate 2, which makes the snap-fitting smoother and can play a role of transition fit during the snap connection.

[0022] Preferably, the left and right sides of the main body and connecting plate 1 are respectively provided with mounting stop seal fitting grooves to ensure the connection sealing during fitting.

[0023] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or replacements can be made without departing from the principles described in the present invention. These improvements or replacements should also be regarded as the scope of protection of the present invention.
