Powder and 2 parts of foaming agents, 1 part of improver and 1 part of adhesive mixing resulting mixture；Feed the mixture into reactor, add 3 parts
Solvent；The reactor is heated to melt mixture, and the mixture of uniform stirring fusing forms plastic cement emulsion；
C, spraying, the corresponding shell in the spiral case air channel is uniformly sprayed by high pressure nozzle by the plastic cement emulsion
On the inwall of body；
D, formed honeycomb sample sound-absorbing ball, from inwall from another high pressure nozzle to the housing for being sprayed with the plastic cement emulsion
Upper spraying liquid nitrogen cooling agent, makes the plastic cement emulsion be quickly cooled to the honeycomb sample sound-absorbing ball.
Preferred embodiment is that in the step b, the improver selects aliphatic alcohol polyethenoxy.
Preferred embodiment is, in the step b, the adhesive selects ABS glue.
Preferred embodiment is that in the step b, the foaming agent selects blowing agent AC.
Preferred embodiment is, in the step b, then to adding 3 parts of dichloromethane solvents in the reactor.
Preferred embodiment is, in the step b, the reactor is heated to 260 degree and melts mixture.
Preferred embodiment is that each described sound-absorption hole is crude fibre hole.
After adopting the above technical scheme, the beneficial effects of the invention are as follows：Due to low noise clarifier spiral case of the invention
Processing technology, wherein low noise clarifier spiral case include housing, and one end of the housing is provided with air outlet, while the centre of housing sets
There is wind inlet, and wind inlet runs through housing, the inside of the housing is spiral case air channel, is set in the corresponding inner walls in spiral case air channel
Have and multiple sound-absorption holes are equipped with some acoustic(al)absorbents, and each acoustic(al)absorbent.So after spiral case air channel is entered from wind inlet, air-flow
Operation and collision generation volume noise are adsorbed and decomposed by acoustic(al)absorbent, so as to greatly reduce the noise of clarifier spiral case generation.And
It is easy to operate because processing step is simple when processing clarifier spiral case using processing technology of the invention, so that in spiral case air channel
Coarse-fibred porous honeycomb sample attraction ball can quickly be formed.Because of processing technology effect of the invention substantially, make it have very
Good prospect.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As depicted in figs. 1 and 2, a kind of processing technology of low noise clarifier spiral case, the low noise clarifier snail processed
Shell includes housing 1, and one end of housing 1 is provided with air outlet 4, and the centre of housing 1 is provided with wind inlet 3, and wind inlet 3 runs through housing 1, shell
The inside of body 1 is spiral case air channel, and the corresponding inwall of housing 1 in spiral case air channel is provided with multiple acoustic(al)absorbents, and each acoustic(al)absorbent
It is provided with multiple sound-absorption holes.Each acoustic(al)absorbent in the present embodiment selects honeycomb sample sound-absorbing ball 2, and above-mentioned each sound-absorption hole is equal
It is crude fibre hole.Each honeycomb sample sound-absorbing ball 2 of the present embodiment is formed by plastic cement spray simultaneously.
As shown in figure 3, the processing technology of low noise clarifier spiral case of the invention, including step：Housing 1 is first made, so
Make to form spiral case air channel in housing 1 again afterwards.Processing technology is further comprising the steps of：
