Abstract
The invention discloses a honeycomb dehumidification silencer which comprises a silencer shell, wherein cylindrical inner wall sound-absorbing pieces are arranged on front and rear inner walls of the silencer shell; a honeycomb silencing piece bracket is mounted on the inner wall on the left side; an inlet neck extending outwards is arranged on the left side wall; a honeycomb silencing piece is mounted on the honeycomb silencing piece bracket; a cylindrical flange plate is connected to the outer side of the inlet neck; and an inlet neck inner wall silencing piece is arranged in the inlet neck, and the inlet neck extends into the silencer shell. According to the invention, the defect that the existing fan silencer is complicated in structure, high in cost and large in size is improved; and moreover, the honeycomb dehumidification silencer disclosed by the invention has the characteristics of simple structure, high manufacturability, small size, low cost and good silencing effect.
Description
Technical field
The present invention relates to deafener field, refer in particular to a kind of honeycomb dehumidifying deafener.
Background technology
In plastic granulating production process, the means using pressure fan conveying and cooling product have become mainstream configuration, because power of fan is bigger, the noise produced is higher, human body and environment is had certain harm, you must use deafener to reduce its noise, at present, although pressure fan deafener is structurally not quite similar, but, generally have that structure is complicated, manufacturing process is poor, noise reduction is than little, relatively costly shortcoming.
Present invention aim at: for the defect that existing muffler for fan structure is complicated, bulky, relatively costly, it is provided that the blower fan honeycomb deafener that a kind of simple in construction, volume are little, overcome the drawbacks described above that existing muffler for fan is deposited.Summary of the invention
The technical problem to be solved there is provided a kind of honeycomb dehumidifying deafener, solves the shortcoming that existing muffler for fan structure is complicated, relatively costly, bulky.
A kind of honeycomb dehumidifying deafener of the present invention, including muffler shell, is provided with cylinder inboard wall sound-absorbing sheet, inner left wall is provided with honeycomb bloop support at inwall before and after described muffler shell, left side wall is provided with outward extending import neck；Being provided with honeycomb bloop on honeycomb bloop support, connecting outside import neck has shell flange sheet, is provided with import neck inwall bloop and extends in muffler shell body in import neck.
Improving further, described honeycomb bloop is formed by stacking by multiple porcelain foaming cellular bloops, is not set in qually spaced on support.
Improving further, described shell flange sheet is made up of corrosion resistant plate or iron plate.
Improving further, described honeycomb bloop support is stainless steel welded support.
The beneficial effects of the present invention is:
Compared with prior art, the present invention improves the shortcoming that existing muffler for fan structure is complicated, relatively costly, bulky, and present configuration is simple, and anufacturability is preferable, and volume is little, cost is relatively low, the preferable feature of erasure effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, a kind of honeycomb dehumidifying deafener, including muffler shell 1, being provided with cylinder inboard wall sound-absorbing sheet 2, inner left wall is provided with honeycomb bloop support 3 before and after described muffler shell at inwall, left side wall is provided with outward extending import neck 4；Being provided with honeycomb bloop 6 by clamp nut 5 on honeycomb bloop support, connecting outside import neck 4 has shell flange sheet 7, is provided with import neck inwall bloop 8 and extends in muffler shell body in import neck.
Wherein, described honeycomb bloop is formed by stacking by the porcelain foaming cellular bloop of multiple sharp angle surface shapes, use superposition, the gap increased between sheet, play loss sound wave transmission, increase air-flow unimpeded, its bloop be designed to sharp angle surface also functions to buffer gas flow, strengthen absorb noise area good effect.
Wherein, described in cylinder inboard wall sound-absorbing sheet, import neck inwall bloop be ceramic foam inwall bloop, play inwall noise reduction, increase steam flow kinetic damping effect.
Wherein, described honeycomb bloop support is stainless steel welded support, plays the fixing ceramic foam honeycomb sheet effect of support.
Wherein, described shell flange sheet is made up of corrosion resistant plate or iron plate, rises and couples supporting role.
The principle of the present invention is: the noise of blower fan comes from the effect that import is centrifugal, when blower fan high speed inspiration air, owing to there being bigger space outside import, unexpected compressed air volume during air-flow inlet.Become instantaneous in volume of air space, the compression creating steam flow sends the sound of perverse ear, changing rapidly of steam flow speed just produces serious noise, for this, this patent uses ceramic foam honeycomb sheet silencing means at air inlet, it it is exactly the drastically change reducing air motion, when air-flow flows in honeycomb, owing to the direction of motion of steam flow is by generation side, the path transformationization of honeycomb, create the sound wave of different directions, air inlet produces the loss absorbed by honeycomb hole on diffuse-reflectance i.e. ceramic foam sheet, then makes the sound wave of all directions cancel each other and has reached the purpose of noise elimination.
This programme test effect contrasts
The invention provides thinking and the method for a kind of honeycomb dehumidifying deafener; the method and the approach that implement this technical scheme are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.Each component part the clearest and the most definite in the present embodiment all can use prior art to be realized.
