Abstract
The utility model discloses a muffler for a blower. The muffler consists of a cross-shaped framework, a cylinder body, tile-shaped muffling blocks and a muffling cone. The muffler is characterized in that a shaft sleeve is arranged in the center of the cross-shaped framework; a mounting plate is arranged at the end of the cross-shaped framework; a flange is welded on the neck of the cylinder body; a sound-absorbing medium is filled in a tile-shaped muffling block framework, and a porous plate is assembled on the inner surface of the tile-shaped muffling block framework; the tile-shaped muffling block framework is provided mounting legs which are assembled on the neck of the cylinder body through screws; the muffling cone is biconical in shape and is assembled in the shaft sleeve of the cross-shaped framework through a muffling cone center through shaft; and the cross-shaped framework is assembled on the neck of the cylinder body through the mounting plate. A porous plate is assembled on the outer surface of the muffling cone. The tile-shaped muffling blocks and the sound-absorbing medium in the muffling cone are easy to disassemble and assemble or replace, so that the sound-absorbing and denoising effects of the muffler are ensured.
Description
Technical field
The utility model belongs to fan manufacturing technology field, is specifically related to a kind of blower fan and uses silencing apparatus.
Background technique
Noise is many-sided to the harm of body and mind, and blower fan is one of many industrial and mining enterprise visual plant, also is one of numerous industrial and mining enterprise pollution source of noise.Blower fan is a kind of supplementary equipment of using always with silencing apparatus, and it is installed in the air channel, can not imitate to reduce blower fan medium-high frequency noise.Conventional fan adopts porous medium to make sound absorbing material with silencing apparatus, also can absorb airborne steam in the time of sound-absorbing, and in a single day the sound-absorbing medium makes moist, and then sound absorption qualities can be had a greatly reduced quality, and conventional fan can not disassembling, assembling and replacing with the sound-absorbing medium in the silencing apparatus.
Summary of the invention
The purpose of the utility model is to design and develop a kind of dismounting of being convenient to, and can be convenient for changing or handle the make moist blower fan of sound-absorbing medium and use silencing apparatus.
The utility model is made up of crossing skeleton, stack shell, watt shape silencing block and noise reduction awl, it is characterized in that the crossing skeleton center establishes axle sleeve, and mounting plate is established in the crossing skeleton end; Stack shell neck welding flange; Watt shape silencing block framework filling sound-absorbing medium, its internal surface assembling porous slab, a watt shape silencing block framework is established installation foot; Be assemblied in the stack shell neck through screw; The noise reduction awl is biconial, wears axle through noise reduction awl center and is assemblied in the axle sleeve of crossing skeleton, and crossing skeleton is assemblied in the stack shell neck through mounting plate.
Said noise reduction awl outer surface assembling porous slab.
In the utility model using process; If the sound-absorbing medium makes moist, sound absorption qualities reduces; As long as remove an end crossing skeleton, just can easily split out watt shape silencing block and noise reduction awl, the sound-absorbing medium in airing or replacing watt shape silencing block and the noise reduction awl; Ressembled silencing apparatus, the performance of silencing apparatus just can be recovered as before.
The utility model beneficial effect is: the sound-absorbing medium in watt shape silencing block and the noise reduction awl is easy to dismounting and handles or change, and can guarantee the absorbing sound and lowering noise effect of silencing apparatus.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cross-sectional schematic.
Among the figure, the 1-crossing skeleton, the 2-axle sleeve, the 3-mounting plate, the 4-flange plate, the 5-stack shell, 6-watt of shape silencing block, 7-watt of shape silencing block framework, 8-sound-absorbing medium, the 9-porous slab, the 10-installation foot, 11-noise reduction awl, axle is worn at 12-noise reduction awl center.
Embodiment
As shown in Figure 1, a kind of blower fan is used silencing apparatus, is made up of crossing skeleton 1, stack shell 5, watt shape silencing block 6 and noise reduction awl 11; It is characterized in that crossing skeleton 1 center establishes axle sleeve 2, mounting plate 3 is established in crossing skeleton 1 end, stack shell 5 neck welding flanges 4; Watt shape silencing block framework 7 filling sound-absorbing media 8, its internal surface assembling porous slab 9, a watt shape silencing block framework 7 is established installation foot 10; Be assemblied in stack shell 5 necks through screw; Noise reduction awl 11 is biconial, wears axle 12 through noise reduction awl center and is assemblied in the axle sleeve 2 of crossing skeleton 1, and crossing skeleton 1 is adorned 3 through mounting plate and fitted over stack shell 5 necks.
11 outer surfaces assembling porous slab 9 is bored in said noise reduction.
The quantity of watt shape silencing block is six in Fig. 2 sectional view.If consider big radian watt shape silencing block easy accessibility, wherein a watt of shape silencing block framework 7 is made wedgewise, and contiguous two pieces watts of shape noise reduction frameworks 7 make fit shapes.If cylindrical shell 5 internal diameters are enough big, then watt shape noise reduction framework 7 transverse section are close to rectangle, do not have the inconvenient problem of dismounting.
In the utility model using process; If sound-absorbing medium 8 makes moist, sound absorption qualities reduces; As long as remove an end crossing skeleton 1, just can easily split out watt shape silencing block 6 and noise reduction awl 11, the sound-absorbing medium 8 in airing or replacing watt shape silencing block 6 and the noise reduction awl 11; Ressembled silencing apparatus, the performance of silencing apparatus just can be recovered as before.
Claims (2)
1. a blower fan is used silencing apparatus, is made up of crossing skeleton, stack shell, watt shape silencing block and noise reduction awl, it is characterized in that the crossing skeleton center establishes axle sleeve; Mounting plate is established in the crossing skeleton end, stack shell neck welding flange, watt shape silencing block framework filling sound-absorbing medium; Its internal surface assembling porous slab; Watt shape silencing block framework is established installation foot, is assemblied in the stack shell neck through screw, and the noise reduction awl is biconial; Wear axle through noise reduction awl center and be assemblied in the axle sleeve of crossing skeleton, crossing skeleton is assemblied in the stack shell neck through mounting plate.
