Abstract
A kind of honeycomb dehumidifying muffler that the utility model discloses, including muffler shell, is provided with cylinder inboard wall sound-absorbing piece, 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；Honeycomb bloop support is provided with honeycomb bloop, outside import neck, is connected with shell flange piece, be provided with import neck inwall bloop in import neck and extend in muffler shell body.The utility model improves complicated, relatively costly, the bulky shortcoming of existing muffler for fan structure, the utility model simple in construction, and anufacturability is preferable, and volume is little, cost is relatively low, the preferable feature of erasure effect.
Description
Technical field
The utility model relates to muffler field, refers in particular to a kind of honeycomb dehumidifying muffler.
Background technology
In plastic granulating production process, use pressure fan to carry and the means of cooling product have become mainstream configuration, because of wind
Acc power is relatively big, and the noise of generation is higher, has certain harm to human body and environment, you must use muffler to reduce it
Noise, at present, although pressure fan muffler is structurally not quite similar, but, generally there is structure complexity, manufacturing process relatively
Difference, noise reduction are than little, relatively costly shortcoming.
The utility model purpose is: for complicated, bulky, relatively costly the lacking of existing muffler for fan structure
Fall into, the blower fan honeycomb muffler that a kind of simple in construction, volume are little is provided, overcomes the drawbacks described above that existing muffler for fan is deposited.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of honeycomb dehumidifying muffler, solves existing blower fan
Complicated, relatively costly, the bulky shortcoming of muffler structure.
A kind of honeycomb dehumidifying muffler described in the utility model, including muffler shell, before and after described muffler shell
Being provided with cylinder inboard wall sound-absorbing piece at inwall, inner left wall being provided with honeycomb bloop support, left side wall is provided with and stretches out
Import neck；Honeycomb bloop support is provided with honeycomb bloop, outside import neck, is connected with shell flange piece, import
It is provided with import neck inwall bloop in neck and extend in muffler shell body.
Improving further, described honeycomb bloop is formed by stacking by multiple porcelain foaming cellular bloops, and unequal-interval
It is arranged on support.
Improving further, described shell flange piece 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 utility model are:
Compared with prior art, the existing muffler for fan structure of the utility model improvement is complicated, relatively costly, bulky
Shortcoming, the utility model simple in construction, anufacturability is preferable, and volume is little, cost is relatively low, the preferable feature of erasure effect.
Brief description
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of honeycomb dehumidifying muffler, including muffler shell 1, before and after described muffler shell at inwall
Be provided with cylinder inboard wall sound-absorbing piece 2, inner left wall be provided with honeycomb bloop support 3, left side wall be provided with outward extending enter
Mouth neck 4；Honeycomb bloop support is provided with honeycomb bloop 6 by clamp nut 5, outside import neck 4, is connected with cylinder
Body flange plate 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, uses
Superposition, the gap increasing between piece, play loss sound wave transmission, to increase air-flow unimpeded, and its bloop is designed to sharp angle surface also
Play buffer gas flow, strengthen the good effect absorbing noise area.
Wherein, the cylinder inboard wall sound-absorbing piece described in, import neck inwall bloop are ceramic foam inwall bloop, rise
To inwall noise reduction, increase steam flow kinetic damping effect.
Wherein, described honeycomb bloop support is stainless steel welded support, rises and supports fixing ceramic foam honeycomb piece work
With.
Wherein, described shell flange piece is made up of corrosion resistant plate or iron plate, rises and couples supporting role.
Principle of the present utility model is: the noise of blower fan comes from the centrifugal effect of import, when blower fan high speed inspiration air
When, 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, and changing rapidly of steam flow speed just produces serious noise, to this end, this patent
Use ceramic foam honeycomb piece silencing means at air inlet, it is simply that reduce the drastically change of air motion, when air-flow is in honeycomb
During flowing, owing to the direction of motion of steam flow is by the path generation side transformationization of honeycomb, create the sound wave of different directions, air inlet
Produce the loss being absorbed by honeycomb hole on diffusing reflection i.e. ceramic foam piece, then make the sound wave of all directions cancel each other and reach
The purpose eliminated the noise.
The utility model provides thinking and the method for a kind of honeycomb dehumidifying muffler, implements the side of this technical scheme
Method and approach are a lot, and the above is only preferred embodiment of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from the utility model principle, can also make some improvements and modifications, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.In the present embodiment, not clear and definite each component part all can use existing skill
Art is realized.
