The combustion engine filtering sound insulation box body is characterized in that: the combustion engine filters sound insulation box still include ventilation system, ventilation system include two sets of ventilation structures, two sets of ventilation structures arrange at the preceding rear end face of box main part, ventilation structure mainly includes air inlet tripe, air inlet muffler, fan, air inlet fire prevention valve and the muffler of airing exhaust, the air inlet muffler arrange the outside rear end face of box main part, the fan arrange the inboard of box main part, link to each other with air inlet muffler and air inlet fire prevention valve, the muffler of airing exhaust arrange the outside front end face of box main part.
Vehicle-mounted combustion engine filter sound insulation box, characterized by: the gas turbine box body further comprises a filtering system, the filtering system is installed on the side face of the air inlet filtering cover, and the filtering system comprises a framework, an outer wall plate and a plate type filter; the framework is formed by welding metal profiles, the outer wall plate is a metal bending plate, the filtering grade of the plate filter is G4, and the plate filter is installed on the framework.
Has the advantages that:
1. the utility model discloses a box main part comprises sound insulation layer, box door group and rain-proof shutter plate, and the sound insulation layer comprises sheet metal, skeleton, perforated plate and sound absorbing material, and the sound insulation layer has that the sound insulation is effectual, and structural strength is high, characteristics such as light in weight. The box door set comprises an outer surface metal plate layer, a sound absorption material, a perforated plate, a door lock, a hinge and the like, and can be used for daily maintenance and overhaul of personnel. The rainproof louver boards are formed by bending after being stamped by metal steel plates and form a detachable structure with the box body main body, and the protruding shape after stamping forming can effectively prevent rain, so that the box body is suitable for outdoor operation.
2. The utility model discloses an it includes frame main part, fixed rain-proof tripe, board-like filter, folded plate formula muffler and unit air inlet flange to admit air the filter mantle, and the frame main part plays the main tributary and supports the effect, and intensity is high, simple structure. The fixed rainproof shutter can effectively prevent rainwater and insects from entering an air inlet channel of the gas turbine. The plate filter provides dry, clean air for the combustion engine. The folded plate type silencer can effectively reduce the air inlet noise of the combustion engine, so that the noise emission of the unit meets the national standard.
3. The utility model discloses a ventilation system includes two sets of ventilation structures, and ventilation structure mainly comprises air inlet tripe, air inlet muffler, fan, air inlet fire prevention valve and the muffler of airing exhaust. The air inlet shutter can effectively prevent rainwater and insects from entering the box body. The air inlet fire-proof valve can ensure that the air inlet is closed quickly after combustible gas leaks or catches fire in the box body, so that the aim of isolating the air inlet from the box body is fulfilled, and the fire point in the box body is extinguished. The silencer adopts a folded plate type silencer, and the folded plate type silencer has the characteristics of light weight, short silencing length, small volume, small occupied space, low manufacturing cost, attractive appearance and no corrosion.
4. The utility model discloses a filtration system has that the wholeness is strong, and area is little, characteristics such as integrated degree is big, filtration system install the filter mantle side of admitting air, filtration system include skeleton, outer wallboard and plate filter, plate filter's filtration grade be G4, large granule dust in the effective filtration air.
5. The utility model discloses a bottom half crossbeam comprises the welding of rectangle tubular section bar, and this crossbeam plays the effect of being connected with the vehicle bottom dish, and the intensity of rectangle tubular crossbeam is high, simple structure, and light in weight can provide stable connection plane for the box main part.
