Abstract
A novel muffler comprises a tubular casing, a muffling layer, a muffling cone and a muffling cone support. The muffling layer is bonded to the inner wall of the tubular casing, a cylinder is arranged in the middle of the muffling cone, cone bodies are connected with two ends of the cylinder, and the bottom faces of the cone bodies are connected with the end face of the cylinder. The muffling cone is connected in a hollow cavity of the tubular casing through the muffling cone support, and the axis of the muffling cone is identical with that of the tubular casing. Compared with similar products, the muffler is good in muffling effect, simple in structure, light in weight, less in material consumption and convenient to install. The muffling value can reach 20-30db, resistance loss is small, a high pressure fan is 40 water millimeters, and a low pressure fan is 10 water millimeters. The muffler is directly connected onto an air outlet of a fan and is applicable to various fans.
Description
Technical field
The technical program belongs to silencing apparatus technical field, specifically a kind of silencing apparatus that is applicable to blower fan.
Background technique
In prior art, in industrial and mining enterprise's production process, the noise that blower fan produces is one of main noise.The general method adopting is, is the pedestal of blower fan isolation ground with padded coaming.This method is that blower fan is rotated and produces noise and ground isolation, can partly eliminate the energy that produces noise.But, because another part noise of blower fan is that wind is made an uproar, said method concerning wind is made an uproar, erasure effect and limited.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of new silencing apparatus, comprises cylindrical outer casing, noise reduction layer, noise reduction cone and noise reduction cone support; Described noise reduction laminating is on the inwall of cylindrical outer casing; The centre of described noise reduction cone is cylindrical body, is connected with respectively taper at cylindrical body two ends, and the bottom surface of taper is connected with cylindrical end face; Described noise reduction cone is bored support by noise reduction and is connected in the hollow cavity of cylindrical outer casing, and the axis of noise reduction cone is identical with the axis of cylindrical outer casing.
Described noise reduction cone support has two groups, lays respectively at two opening ends of cylindrical outer casing, and the summit place of two noise reduction cones is connected with a noise reduction cone support respectively.
Described noise reduction cone comprises coated housing and packing material; Described packing material is in coated housing, and through hole gathers in encasement surface.
Described noise reduction layer comprises coated housing and packing material; Described packing material is in coated housing, and through hole gathers in encasement surface.
Described packing material is rock wool, and filling density is 60Kg/m
3.
Two opening ends of described cylindrical outer casing are connected with flange.
Compared with similar products, this serial silencing apparatus soundproof effect is higher, and its noise elimination value can reach 20～30 decibels, and drag losses is also very little, and high pressure positive blower is 40 column, and fan with low voltage is 10 column; Simultaneously simple in structure, lightweight, consumptive material is few, easy for installation.This silencing apparatus is directly connected to the exhaust outlet of blower fan, is applicable to multiple blower fan.
