Abstract
The utility model belongs to the technical field of a polyvinyl butyral (PVB) extrusion machine workshop exhaust system, in particular to a soft exhaust for reducing noise. A basic framework of the exhaust duct is formed by rebars, windbreaker cloth is arranged outside the framework in a wrapped mode to form an exhaust pipeline, the outer end of the exhaust pipeline penetrates through an exhaust opening on a roof of a workshop and extends outside the roof of the workshop, an exhaust fan is arranged at the outer end of the exhaust pipeline extending out of the roof of the workshop, and an downward exhaust inlet of the exhaust pipeline is arranged in the workshop. By utilizing the exhaust pipeline formed by the basic framework of the exhaust pipeline and the windbreaker cloth, the soft exhaust for reducing the noise greatly reduces huge metal trill generated inside the workshop because of air exhausting of a metal pipeline. Noise generated by the metal pipeline is 89 dB originally and 70 dB now, thereby according with the rule stated by environmental protection administration that the noise of a workshop is no larger than 85 dB, and meanwhile, the present noise of 70 dB is lower that the rule. An outer cover of film-in glass adopts colorized film-in glass, thereby being elegant and sound-proofing. The soft exhaust for reducing the noise is further applicable to occasions where air exhaust is needed in any workshop.
Description
Technical field:
The utility model belongs to PVB extruder workshop exhaust system technical field, refers in particular to a kind of soft raft wind pipeline that reduces noise.
Background technology:
As everyone knows, the workshop with the exhaust blower pipeline generally with material take iron sheet, aluminium alloy or stainless steel sheet| as main.The major defect of the exhaust duct made from metal sheet is: in exhaust blower air draft process, the friction of wind and pipeline and pipeline are under the effect of inner and outer air pressure, and metal sheet can constantly produce huge vibration, sends and makes the insufferable metal trill of people.Exhaust blower has also produced noise when discharging workshop hot blast and pernicious gas, have a strong impact on the Workshop Production environment, affects workshop workman's physical and mental health.
Summary of the invention:
But the purpose of this utility model provides a kind of effective noise reduction function, improves the soft raft wind pipeline of Workshop Production environment.
The utility model is achieved in that
A kind of soft raft wind pipeline that reduces noise, reinforcing bar forms the exhaust duct basic framework, be provided with windbreaker cloth in the framework outsourcing and form exhaust duct, the exhaust outlet that the outer end of exhaust duct is passed on the roofing of workshop stretches out outside the roofing of workshop, the outer end of the exhaust duct outside stretching out the workshop roofing is provided with exhaust blower, and the inlet scoop of exhaust duct is arranged in the workshop down.
Above-mentioned exhaust duct basic framework includes several and is 90 ° turning round, it is parallel with the workshop roofing to stretch out the outer part of workshop roofing, the exhaust duct basic framework is arranged by several rectangular supports, be connected and fixed by reinforcing bar between the adjacent support, the reinforcing bar in the corner with arc connects.
The above-mentioned outer part of workshop roofing of stretching out is arranged on roofing top, workshop by the exhaust duct bracket-suspending.
The above-mentioned inlet scoop of exhaust duct basic framework from the exhaust outlet on the roofing of workshop to exhaust duct that is provided with windbreaker cloth is outside equipped with folder film glass outer cover.
Above-mentioned windbreaker cloth is fixed on the exhaust duct basic framework with iron hoop.
Above-mentioned windbreaker cloth is the terylene windbreaker cloth.
Above-mentioned folder film glass outer cover is formed by colour folder film glass.
Folder film glass on the above-mentioned folder film glass outer cover is that drawing and pulling type connects.
Above-mentioned folder film glass covers on the place, inlet scoop outward and is formed with enlarging.
The advantage that the utility model is given prominence to compared to existing technology is:
1, the utility model utilizes the exhaust duct that exhaust duct basic framework and windbreaker cloth form, the huge metal trill that sends when greatly reducing workshop internal cause metallic conduit air draft, originally the noise of metallic conduit generation is 89 decibels, present noise is 70 decibels, and the Noise In Workshop that is lower than environmental administration's regulation is not more than 85 decibels regulation;
2, the folder film glass outer cover of the utility model setting adopts colored folder film glass, and is both attractive in appearance, again sound insulation;
3, the folder film glass on the folder film glass outer cover of the present utility model adopts the structure of drawing and pulling type, easy access;
4, windbreaker cloth of the present utility model adopts the terylene windbreaker cloth, and is not only windproof but also firm;
5, the utility model need in the various workshops to be applicable to the occasion of air draft.
Description of drawings:
Fig. 1 is simplified schematic diagram of the present utility model.
The specific embodiment:
The below is further described the utility model with specific embodiment, referring to Fig. 1:
A kind of soft raft wind pipeline that reduces noise, reinforcing bar forms exhaust duct basic framework 5, be provided with windbreaker cloth 6 in framework 5 outsourcings and form exhaust duct, the exhaust outlet 2 that the outer end of exhaust duct is passed on the workshop roofing 1 stretches out outside the workshop roofing 1, the outer end of the exhaust duct outside stretching out workshop roofing 1 is provided with exhaust blower 4, exhaust blower 4 is from about 2 about ten meters of workshop roofing 1 exhaust outlets, to reduce exhaust blower 4 noises to the impact in workshop, the inlet scoop 9 of exhaust duct is arranged in the workshop down, according to the true bearing setting of PVB workshop.
Above-mentioned exhaust duct basic framework 5 includes several and is 90 ° turning round, the part of stretching out outside the workshop roofing 1 is parallel with workshop roofing 1, exhaust duct basic framework 5 is arranged by several rectangular supports, rectangular support is to adopt the steel bar welding of φ 8mm to be connected into the rectangular support frame that ratio is 40 * 60cm, spacing between support and the support is 1m, be connected and fixed with reinforcing bar between the adjacent support, the reinforcing bar in the corner with arc connects, and is smooth to keep air draft.
Above-mentioned stretches out workshop roofing 1 part outward by exhaust duct support 3 unsettled workshop roofing 1 tops that are arranged on.
The above-mentioned inlet scoop 9 of the exhaust duct basic framework 5 that is provided with windbreaker cloth 6 from the exhaust outlet 2 on the workshop roofing 1 to exhaust duct is outside equipped with folder film glass outer cover 7.
Above-mentioned windbreaker cloth 6 usefulness iron hoops are fixed on the exhaust duct basic framework 5.
