Description
Technical field
The present invention particularly relates to a kind of volute of blower for reducing noise and being adjustable air outlet size in relation to a kind of spiral case.
Background technique
Currently, blower, especially dedusting fan are for improving air quality, improving cross-ventilated equipment, using normal
Short axle ventilating and purifying air system is pressed, the purification on the spot of dust can be effectively realized, especially have higher dedusting to respirable dust
Efficiency.Dedusting fan is the important component of high powered diesel locomotive traction electric machine VENTILATING SYSTEM BY VOLTAGE STEP, is generated at work
Aerodynamic noise can produce a very large impact environment with mechanical noise.And the air outlet of current dedusting fan is unadjustable, can not
Meet the dust removing effects under different situations.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of blowers for reducing noise and being adjustable air outlet size
Spiral case.
In order to achieve the above objectives, the present invention provides a kind of volute of blower comprising the first side plate, the second side plate and volute
Plate, first side plate and the second side plate are separately fixed at the right and left of the volute plate, and the volute plate is by plate curved bend
The discontiguous curved in the both ends Qu Ercheng, and one end is high, the other end is low, and the high one end of the volute plate is along a tangential direction to extension
It stretches to form top plate, the low one end of the volute plate extends outward to form bottom plate, and first side plate is to the top plate and bottom plate direction
Left front side plate is extended to form, second side plate extends to form forward right side plate to top plate and bottom plate direction, wherein the front left side
Plate, forward right side plate, top plate and bottom plate besieged city volute of blower air outlet, the air outlet inner wall be equipped with muffler.
The muffler is set on the inside of the bottom plate and on the inside of top plate.
First side plate and the second side plate inner wall also are provided with the muffler.
The muffler surface is irregular concaveconvex shape.
The muffler is acoustical cotton or foamed glue.
At the air outlet, it is outward extended with work respectively at the edge of the left front side plate, forward right side plate, top plate and bottom plate
The extended plate of dynamic connection.
The extended plate expands radially outward, or closes up to the air outlet contract.
The rear side of the extended plate is equipped with regulating device.
Volute of blower of the invention can reduce noise, and be adjustable air outlet size, to meet different noise reduction dedusting demands.
Detailed description of the invention
Fig. 1 is the schematic perspective view of volute of blower of the present invention；
Fig. 2 is the internal cross section figure of volute of blower of the present invention；
Fig. 3 is the structural schematic diagram of another embodiment of volute of blower of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is the present invention
A part of the embodiment, instead of all the embodiments, the embodiment of the present invention are exemplary, it is intended to it is used to explain the present invention,
And it is not considered as limiting the invention.
As shown in Figure 1, volute of blower of the invention, including the first side plate 1, the second side plate 2 and volute plate 3, volute plate 3 by
Plate arc-shaped bend forms the discontiguous curved in both ends, and one end is high, and the other end is low, and the high one end of volute plate 3 is tangentially square
To being outward extended with top plate 30, the low one end of volute plate 3 is outward extended with bottom plate 31, and the first side plate 1 is to top plate 30 and bottom plate 31
Direction extends to form left front side plate 10, and the second side plate 2 extends to form forward right side plate 20 to top plate 30 and 31 direction of bottom plate, wherein left
Front side board 10, forward right side plate 20, top plate 30 and bottom plate 31 are encircled a city the air outlet 6 of volute of blower.
First side plate 1 and the second side plate 2 are separately fixed at the right and left of volute plate 3, and 6 inner wall of air outlet can be equipped with noise reduction
Device 60, preferably muffler 60 are set on the inside of bottom plate and on the inside of top plate, and 60 surface of muffler is irregular concaveconvex shape, noise reduction
Device can be acoustical cotton or foamed glue.The muffler back side can be coated with adhesive sticker, can peel protection sheet off when in use, directly by muffler
It is pasted in air outlet.
It is as shown in Figure 2 can also to be equipped with muffler 60(for the first side plate 1 and 2 inner wall of the second side plate in the present invention), more to have
The noise for reducing blower and generating of effect.
As shown in figure 3, at air outlet in the present invention, left front side plate 10, forward right side plate 20, top plate 30 and bottom plate 31 side
Along the extended plate 4 for being outward extended with flexible connection respectively, which can expand radially outward, to increase air outlet
