Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model; below in conjunction with accompanying drawing, this utility model is described in detail; the description of this part is only exemplary and explanatory, and protection domain of the present utility model should not have any restriction effect.
As shown in figs 1 to 6, concrete structure of the present utility model is: a kind of big flow fan acoustic filter, it includes urceolus 2, and described urceolus about 2 both ends of the surface are provided with mounting flange 1；Described urceolus 2 is internally provided with the first tubular muffler material 3；Described first tubular muffler material 3 is interspersed to be connected on mounting flange 6；Described mounting flange 6 outer wall is connected with urceolus 2 inwall；Described first tubular muffler material about 3 two ends are provided with anechoic sheet 5；Described anechoic sheet 5 is cylindric, and its outer wall is connected with urceolus 2 inwall；Described anechoic sheet 5 is provided with air vent 501；Described air vent 501 is in the same size with the internal diameter of the pipeline of described first tubular muffler material 3 to be mated；Described urceolus about 2 two ends inwall is provided with the second tubular muffler material 4.
Preferably, described first tubular muffler material 3 quantity is multiple, is arranged on the middle part of urceolus 2, and uniformly arranges according to the circumferencial direction of urceolus 2.
Preferably, described anechoic sheet 5 is connected on the first tubular muffler material 3；The quantity of described air vent 501 is multiple, and consistent with the first tubular muffler material 3 quantity mates.
Preferably, two, described left and right the second tubular muffler material 4 is for being symmetrical arranged, and its outer face is concordant with mounting flange 1 outer face, and its inner face is connected on anechoic sheet 5.
As shown in Figure 6, first produce at noise during fan operation is absorbed by anechoic sheet 5 to noise elimination process of the present utility model, and a part of noise is reflected back；Unabsorbed noise has carried out absorption repeatedly inside the second tubular muffler material 4 and the first tubular muffler material 3, thus improve soundproof effect.Due to the resistance of wind speed is less in the process of fan operation, therefore ventilation effect is better.
