Embodiment Construction

[0018] In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0019] like Figure 1-3 As shown, the present invention is an aluminum plate-based fan protection casing, which includes two semicircular half shells 2 . The two half-shells 2 are fastened together to form a cover body. The two half-shells 2 have a centrosymmetric structure with the center of the cover body as a symmetrical point. By designing the cover body as two half shells 2 structures, the left and right sides of the fan can be directly fitted during the installation process, which is very convenient.

[0020] The front end of the half shell 2 is provided with an air outlet, and the rear end of the half shell 2 is fixedly connected with a tailgate 7 . This design can provide good protection for the exhaust fan from the rear. A half-circle installation ring 3 is fixedly connected to the h...

Abstract

The invention provides an air fan protection shell based on aluminum plates. The air fan protection shell comprises two half shell bodies, the two half shell bodies are buckled and closed into a hoodbody and are of a central symmetry structure with the center of the hood body being the symmetry point, the front ends of the half shell bodies are provided with air outlets, the rear ends of the halfshell bodies are fixedly connected with rear baffles, the parts, on the peripheries of the air outlets, of the half shell bodies are fixedly connected with semicycle installation rings, a dustproof net is installed inside the installation rings, the parts, at the buckled and closed positions of the two half shell bodies, of the half shell bodies are provided with half shell body installation blocks, the half shell body installation blocks are provided with installation holes, installation surfaces of the installation blocks are provided with protrusions and grooves convenient to install and position, and the protrusions are fixed with the corresponding grooves in an insert connection manner. The air fan protection shell based on the aluminum plates has the beneficial effects that by meansof the manner that the installation rings are internally provided with the dustproof net, the probability of outside dust, fine cellosilk and the like invading into the inner portion of an air exhaust fan can be effectively lowered, so that the capacity of keeping clean of the air exhaust fan is greatly improved, and the cleaning frequency is significantly lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment and components thereof, in particular to an aluminum plate-based fan protection casing. Background technique [0002] In industrial production, exhaust fans are one of the common ventilation and cooling equipment. Because the thickness of the fan blades of the exhaust fan is relatively thin, a fan cover is usually added on the outside of the exhaust fan to protect the exhaust fan from being damaged due to accidents. In industrial workshops, the air quality is generally poor, especially in workshops that produce powder or fiber filaments. The exhaust fans will inevitably be polluted if they work in this environment for a long time. When the dust or fine fibers accumulate to a certain extent, these exhaust fans will not be able to operate normally. For this reason, the staff needs to regularly clean and maintain the exhaust fan. Due to the high installation position of the traditiona...
