Abstract
The invention discloses a low-noise silencer of a double-cavity micro-pore plate. A No.1 middle connection pipe (13) and a No.2 middle connection pipe (14), which are arrayed up and down, are connected with a No.1 micro-pore plate (11) and a No.2 micro-pore plate (12) in parallel; the No.1 middle connection pipe (13) is connected with an air outlet pipe (2); the No.2 middle connection pipe (14) is connected with an air inlet pipe (3); the No.1 micro-pore plate (11), the No.2 micro-pore plate (12), the No.1 middle connection pipe (13) and the No.2 middle connection pipe (14) are mounted in a cavity of a shell (1); the air outlet pipe (2) and the air inlet pipe (3) stretch out of the shell (1); a flange (8) is connected onto the air inlet pipe (3); an upper end cover (5) sleeves the air outlet pipe (2) and is fixedly connected with one end of the shell (1); a lower end cover (9) sleeves the air inlet pipe (3) and is fixedly connected with the other end of the shell (1), so that the silencer is wholly formed. The low-noise silencer is used for reducing exhausting noises of engines of agricultural machines and engineering machines, the power loss of the engines is reduced, and the hearing loss and physical and psychological health of drivers are protected.
Description
Technical field
The present invention relates to the silencing apparatus being used as to reduce exhaust sound, reducing engine power loss, be specifically related to the engine exhaust low-noise muffler for dual-cavity micropore plate of farm machinery, engineering machinery.
Background technique
Noise makes people's worry, disagreeable, or even harmful sound, and the physical and mental health of what noise pollution was serious affect people, gently then upsets the normal life of people, heavy then hearing damage, initiation various diseases.Therefore, along with the raising of economic development people's living standard, noise pollution more and more receives publicity, and noise pollution causes the great attention of country and relevant industrial department already.
Summary of the invention
The object of the invention is to: provide a kind of low-noise muffler for dual-cavity micropore plate, this silencing apparatus is for reducing the exhaust sound of farm tractor, engineering mechanical device, and engine power is not lost with noise reduction simultaneously.
Technical solution of the present invention is: in the chamber of housing, install clamping plate sound absorption mechanism composition silencing apparatus, described clamping plate sound absorption mechanism comprises a microwell plate, No. two microwell plates, connecting leg in No., connecting leg, steam outlet pipe and suction tude in No. two, connecting leg, a microwell plate in parallel and No. two microwell plates on connecting leg in No. two in No. of being arranged above and below, in No. one, connecting leg connects steam outlet pipe, in No. two, connecting leg connects suction tude, form clamping plate sound absorption mechanism; A microwell plate of clamping plate sound absorption mechanism, No. two microwell plates, connecting leg in No., connecting leg is arranged in the chamber of housing in No. two, steam outlet pipe and suction tude are stretched out outside housing, adpting flange in suction tude, upper end cap is enclosed within steam outlet pipe and one end connected firmly at housing, lower end cap to be enclosed within suction tude and the other end connected firmly at housing, overallly forms silencing apparatus.
Wherein, flange and lower end cap connect firmly lower stiffening rib.
Wherein, upper end cap and steam outlet pipe connect firmly stiffening rib.
Wherein, connect firmly protective net support at housing and upper end cap, lower end cap weld, protective net connects firmly on protective net support.
Wherein, surface of shell spraying high-temperature coating.
The present invention has the following advantages: 1, in silencing apparatus inner chamber, assemble two middle connecting legs, soundproof effect is good compared with the double-outspreading silencing apparatus of a middle connecting leg, its main cause is that suction tude and two middle connecting legs stagger certain distance, air-flow enters middle gas tube after turnover, fraction just must enter middle gas tube after 180 ° of turnovers, and the distribution of this Flow Field in Muffler produces very regular with whirlpool.
2, each abrupt change of cross-section place of this silencing apparatus all arranges pod apertures, effectively improves the flowing of internal gas, reduces the intensity that whirlpool produces, and reduces drag losses.
3, double-deck microwell plate is adopted to form inlet air pathway, air column outside aperture pore-throat on plate and empty chamber air form a clamping plate sound absorption structure, when outside noise frequency is identical with elastic system natural frequency, small aperture place air is caused strongly to resonate, produce violent friction, thus consume acoustic energy.
4, outside suppressor case, the protective net of some strength and length is fixedly connected with, in case operator are burned accidentally.
5, suppressor case appearance spraying high-temperature coating, makes Muffler Performance more superior.
Accompanying drawing explanation
Fig. 1 is schematic appearance of the present invention.
