Description
Technical field
The present invention relates to a kind of fans silencer, particularly a kind of booster silencer for air outlet adopting all-plastic to make.
Background technique
At present, ventilation system is an important component part of pit mining, it is the basic guarantee of mine safety production, the effect of booster (hereinafter referred to as portable blower) is in Mine Production, continually by fresh air conveying to mining face under mine, staff is breathed and is diluted and get rid of various poisonous, the harmful gas in down-hole and mine dust, creates good working environment, ensures the healthy and safety of underground operators.
Current countries in the world are all the general objectives around energy saving and protection of the environment in the research of mine local ventilator.Energy saving, raise the efficiency in, one is adopt advanced technology and equipment, improve accuracy of manufacturing, the efficiency of blower fan is made to improve 5%-10% to some extent, two is the numerical simulation epoch having entered now ternary N-S equation, corresponding blower fan actual flow model is established to booster, utilizes computer technology stream field to carry out computational analysis.Adopt Three-dimension flow impeller, make the unit efficiency of blower fan obtain further raising.In protection of the environment, reduce in noise, mine local ventilator adopts clad type structure, is improved by the optimization of pneumatic design and selecting of sound-absorbing material meanwhile.In this regard, the noise of external blower fan generally 5-10dB(A lower than domestic like product).There are Hao Dun company of Britain, the Mitsui three pond company of Sulzer company of Switzerland and Japan, the Ke Fu Man etc. of Germany in company main abroad, and there are Chongqing Mei Ke institute, Hubei match good fortune etc. in domestic main company.
My company, since the eighties exploitation in last century JBT, YBT booster series, has occupied considerable status, one of these series product leading products also becoming company in mine ventilator market always at home.Along with the increase of blower fan manufacturing firm, market competition is more and more fierce, and quality, price are also more and more responsive in market competition.This just proposes higher requirement to us: continue to optimize manufacturing process, improve product performance, strengthen cost control.Around this center requirement, we are doing various trial and research always, also achieve some achievements.Product structure and performance, progressively had and improved and promote, also make the technical merit of mine local ventilator of company maintain the leading position at home, product receives the extensive approval of user always.
At present my mine local ventilator of company mainly FBY series flame-proof type forced axial flow booster and FBDY series explosion-proof type press in type disrotatory axial flow local ventilating fan for mine be main, the motor of this two classes blower fan all adopts YBF2 series explosion separation motor; Casing, impeller, silencer are all with the welding of Ordinary Steel material, are processed into; The weight of complete machine lays particular stress on, and is inconvenient to carry under mine.Silencer is the bundling type structure adopting orifice plate to add noise elimination cotton, and soundproof effect is not obvious.Noise differs greatly according to blower fan model, and № more than 6.0 is to revolving air-blower noise generally at 93 ~ 105dB(A), the FBY № 5.6/30 not with baffler even reaches 110dB(A).Noise mainly concentrates on medium, high frequency scope, ear-piercing shriek, has had a strong impact on normal work and the physical and mental health of operating worker.Sometimes even mask driving sound, machine operation sound and electric bell signal sound, have certain potential safety hazard.
So, the development of mine local ventilator progressively with efficient, low noise, light weight for target.Anhui in 2007 China auspicious invention integral molded plastic impeller, solves the technology barriers such as the fire-retardant and antistatic that plastics use in down-hole.Injection molding, it is leaf Well-recovered, and Leaf positional distribution is even, improves aerodynamic performance.According to test result, injection molding impeller can make the highest total pressure efficiency of blower fan promote more than 5%, plays good effect to mine is energy-conservation.My company in 2007 have developed electric machine stand and flow blower casing is welded into overall all-in-one machine structure, enormously simplify the mounting process of blower fan.
