Description

Axial fan shell mounting structure

Technical Field

The utility model relates to the field of fan shells, in particular to an axial flow fan shell mounting structure.

Background

The axial flow fan has very wide application, namely, the air flow in the same direction with the axis of the fan blade, such as an electric fan, and the fan of the air conditioner external unit is an axial flow running fan. This is called "axial flow" because the gas flows parallel to the fan axis. Axial fans are commonly used in applications where flow requirements are high and pressure requirements are low. The axial flow fan fixes the position and moves the air. The axial flow fan mainly comprises a fan impeller and a shell, and has a simple structure but very high data requirements.

The motor of traditional axial fan all is through support direct mount on the casing, for example, the patent of grant bulletin number CN217380945U discloses an explosion-proof axial fan convenient to maintain, including the whole inner protective housing that is hollow cylinder structure, the inner protective housing, the outside is coaxial to be provided with outer protective housing, just the inner protective housing is in the installation wall inside, and the outer protective housing with inner protective housing internally mounted has the flabellum, explosion-proof motor installs the inner protective housing with inside the outer protective housing, the mounting panel, fixed mounting is in inner protective housing surface, inside support frame installs explosion-proof motor with between the flabellum.

The novel structural design is adopted in the patent, so that the device can separate the inner protective shell from the outer protective shell by utilizing the external rotating button when the device needs to be overhauled, and the fan blade and the motor are taken out along with the outer protective shell, thereby being convenient to maintain and overhaul; however, similarly, the motor in the above patent is first installed at one end of the inner protective housing through the inner support frame and the outer protective housing, whereas the other end of the inner protective housing is installed on the wall surface through the installation plate; the weight of the motor needs to be born by the inner protective shell, the inner protective shell is easy to deform after long-time use,

therefore, there is a need for an improvement in such a structure to overcome the above-mentioned drawbacks.
