Abstract
A tubular/disc combined muffler for a blower is characterized in that the outlet of a disc muffler is hermetically connected and fixed with the inlet of a tubular muffler. The tubular/disc combined muffler adopts that the noise of a burner blower is transmitted in a wave mixing way as the theoretical principle, combines the advantages of the tubular muffler and the disc muffler, and overcomes the shortcomings of the muffler in the prior art, including large volume, high weight, inconvenient use and installation and poor noise elimination effect. The tubular/disc combined muffler has the advantages of small volume, light weight, small air flow resistance, good noise elimination effect, large air intake, and so on. The noise of the blower installed with the muffler is reduced by more than 30 db.
Description
Technical field
The utility model belongs to the pipeline oil transportation equipment technical field.
Background technique
At present, when adopting the line transportation oil, under the microthermal climate condition, oil can cause and solidify and cause mobile extreme difference, therefore also heating plant need be arranged at the oil pump station of setting up, the muffling device volume of existing heating plant is big, weight big, use installation inconvenient, and there is the long shortcoming of silencers channel in trumpet type silencer noise reduction simultaneously, and the disc type baffler uses separately and has erasure effect shortcoming not up to standard.Can not satisfy the air output problem of blower fan.
Summary of the invention
The purpose of this utility model is: provide a kind of blower fan tubular type to combine the blower fan baffler with disc type, it is big that it has solved volume, the problem that erasure effect is bad.
The technical solution of the utility model is: with the disc type silencing end and the trumpet type silencer import is airtight is connected and fixed.
The beneficial effects of the utility model are: according to the combustion fan noise is that smear passes ripple (existing shear wave has compressional wave again) as theoretical foundation, the advantage of compatible tubular type and disc type baffler, change that the conventional muffler volume is big, weight is big, use inconvenience, the unfavorable shortcoming of erasure effect are installed, advantage such as it has that volume is little, in light weight, air flow resistance is little, good muffling effect, air output are big, in the blower fan that examination is installed, the fan noise that this baffler is installed will reduce more than 30 decibels.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, disc type baffler, the 2nd, trumpet type silencer, the 3rd, disc type baffler intake grill, the 4th, trumpet type silencer exhaust outlet, the 5th, trumpet type silencer and disc type baffler joint.
Tubular type noise reduction part: the tubular type noise reduction partly is the main noise reduction part of muffling device, and it is to be made by the 16MnR material, applies sound-absorbing material and sound absorbing paint simultaneously in the pipe, and the noise that intermediate frequency and high frequency are produced all has bigger noise elimination effect.
Disc type noise reduction part: the disc type noise reduction partly is another main noise reduction part of muffling device.It also is to be made by the 16MnR material, and interior simultaneously sound-absorbing material and the sound absorbing paint of applying can reduce air power noise.Mainly utilize the porous sound absorption material to reduce noise.Sound-absorbing material is fixed on the inwall of disc type air-flow path or and in pipeline, arranges, just constituted resistive baffler according to certain way.When sound wave entered resistive baffler, a part of acoustic energy rubbed and changes into thermal dissipation to fall in the hole of porous material, and the sound wave by baffler is weakened.So because the disc type baffler is to the effective effect that can reach the expection noise reduction of medium-high frequency noise elimination.
Tubular type and disc type attachment portion: it is the very important position of muffling device that tubular type is connected with disc type, and it partly couples together disc type noise reduction part with the tubular type noise reduction by 12 bolts and rubber washer, has solved hard connection vibration problem and joint sealing problem.Intake grill: intake grill is the assurance whether the combustion fan air quantity satisfies the equipment requirement.The size of intake grill is decided by the air output of blower fan.
