Abstract
The utility model discloses a kind of fork truck impedance composite muffler, comprise muffler body, suction tude, outlet pipe, described suction tude, one end of outlet pipe is respectively equipped with suction tude leg, outlet pipe leg, it is characterized in that: described muffler body includes cylindrical shell, the two ends of described cylindrical shell are separately installed with air inlet end cap, exhaust end cover, in described cylindrical shell, be provided with air inlet inner tube, middle inner tube, exhaust inner tube, dividing plate, the air inlet port of described air inlet inner tube and suction tude are connected, described exhaust inner tube port and outlet pipe are connected, described air inlet inner tube, middle inner tube, exhaust inner tube is through the dividing plate composition silencing cavity of inner barrel, in described silencing cavity, be provided with muffler material.The sound-absorbing cover that the utility model anechoic room adopts utilizes bi-material compressing, easy to assembly, and cost is cheaper than the single muffler material with Steel Wool.Soundproof effect is better than single use basalt cotton.Through evidence, under fork truck full-speed state, silencing apparatus insertion loss is than the single increase 10% with basalt cotton.
Description
Technical field
The utility model relates to a kind of silencing apparatus, specifically a kind of fork truck impedance composite muffler.
Background technique
In recent years, Chinese fork truck market sales volume is with annual more than 30% mean velocity rapid growth; Wherein internal combustion large-tonnage fork truck is with the carrying capacity of its super large, the adaptive faculty of rugged environment, favor in the handling market that enjoys flexibly, and demand doubles every year, but powerful power depends on the motor of large air displacement and realizes, the use of large air displacement motor will certainly produce very large noise.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of simple in structure, good muffling effect, fork truck impedance composite muffler that cost is low.。
The technical solution of the utility model is:
A kind of fork truck impedance composite muffler, comprise muffler body, suction tude, outlet pipe, described suction tude, one end of outlet pipe is respectively equipped with suction tude leg, outlet pipe leg, it is characterized in that: described muffler body includes cylindrical shell, the two ends of described cylindrical shell are separately installed with air inlet end cap, exhaust end cover, in described cylindrical shell, be provided with air inlet inner tube, middle inner tube, exhaust inner tube, dividing plate, the air inlet port of described air inlet inner tube and suction tude are connected, described exhaust inner tube port and outlet pipe are connected, described air inlet inner tube, middle inner tube, exhaust inner tube is through the dividing plate composition silencing cavity of inner barrel, in described silencing cavity, be provided with muffler material.
Further, described exhaust inner tube exhaust port one side is provided with one deck muffler material, and described muffler material outside is provided with sleeve pipe.
Further, described muffler material is by basalt cotton and Steel Wool is compound forms.
Further, the position contacting with described quieter material in the air inlet inner tube of described silencing apparatus, middle inner tube, exhaust inner tube is evenly equipped with a lot of apertures.
The beneficial effects of the utility model are:
The sound-absorbing cover that the utility model anechoic room adopts utilizes bi-material compressing, easy to assembly, and cost is cheaper than the single muffler material with Steel Wool.Soundproof effect is better than single use basalt cotton.Through evidence, under fork truck full-speed state, silencing apparatus insertion loss is than the single increase 10% with basalt cotton.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model silencing apparatus internal structure schematic diagram.
Embodiment
As depicted in figs. 1 and 2, a kind of fork truck impedance composite muffler of the present utility model, comprise muffler body 1, suction tude 2, outlet pipe 3, described suction tude 2, one end of outlet pipe 3 is respectively equipped with suction tude leg 4, outlet pipe leg 5, it is characterized in that: described muffler body 1 includes cylindrical shell 6, the two ends of described cylindrical shell 6 are separately installed with air inlet end cap 7, exhaust end cover 8, in described cylindrical shell 6, be provided with air inlet inner tube 9, middle inner tube 10, exhaust inner tube 11, dividing plate 12, air inlet port and the suction tude 2 of described air inlet inner tube 9 are connected, described exhaust inner tube 11 ports and outlet pipe 3 are connected, described air inlet inner tube 9, middle inner tube 10, exhaust inner tube 11 forms silencing cavity 13 through the dividing plate 12 of cylindrical shell 1 inside, in described silencing cavity 13, be provided with muffler material 14.
Further, described exhaust inner tube 11 is provided with one deck muffler material 14 near port one side, and described muffler material 14 outsides are provided with sleeve pipe 15.
Further, described muffler material 14 is by basalt cotton and Steel Wool is compound forms.
Further, the position contacting with described quieter material 14 in the air inlet inner tube 9 of described silencing apparatus 1, middle inner tube 10, exhaust inner tube 11 is evenly equipped with a lot of apertures.
The utility model working principle: gas enters silencing apparatus inside through suction tude, a part enters by aperture the sound absorption cavity that is furnished with sound-absorbing material, when a part is discharged in least significant end cavity without relief opening, still need to circle round to sound absorption cavity, in sound absorption cavity, a part of acoustic energy rubs and energy transform into heat energy is consumed in the space of quieter material, and another part conducts to other chambers of silencing apparatus.Finally import outlet pipe into, be furnished with the sealed environment of eliminating the noise of sound absorbing material and steel pipe composition at outlet pipe exhaust port, noise is consumed again, thereby reaches better acoustically effective.
