Abstract

The invention relates to an efficient multi-air outlet energy-saving anti-explosion fan, which comprises a volute (1), an impeller (2) and a motor (3), wherein the volute (1) comprises an air inlet device (11), a front side plate (12), an air tongue (13) and a rear side plate (14), the air tongue (13) is connected between the inner edge of the front side plate (12) and the outer edge of the rear side plate (14), and adopts a flat air tongue or a curve air tongue, and the front side plate (12), the rear side plate (14) and the air tongue (13) are connected into a hollow cylindrical body or a hollow multilateral body; and the impeller (2) adopts a back tilting impeller, and comprises a front plate (21), a blade (22), a rear plate (23) and a hub (24), the blade (22) is connected between the front plate (21) and the rear plate (23), and adopts a single plate double-arc blade, the double-arc blade respectively is a first arc blade and a second arc blade, and the first and the second arc blades extend from the edge of the impeller to the middle to be arranged end to end. The fan provided by the invention has the advantages of small volume, larger whole air outlet area, high static pressure efficiency, lower noise and the like.

Description

technical field [0001] The utility model relates to a fan. It belongs to the technical field of wind power machinery. Background technique [0002] Before the invention was made, all blowers had only one air inlet and one air outlet, and there was no fan that only produced pure static pressure and had multiple air outlets. In particular, the fan formed by the original fan design concept has disadvantages such as large volume, small air outlet area, low static pressure efficiency, and high noise. Usually the dynamic pressure of the fan accounts for 10~30% of the total pressure or even higher. Contents of the invention [0003] The purpose of this utility model is to overcome the above-mentioned shortcomings, to provide an effect that can make the fan obtain the maximum static pressure, and reduce the outlet dynamic pressure to the greatest extent, thereby forming a high-efficiency energy-saving multi-air outlet that converts all energy into the static pressure of the suct...
