Abstract

The utility model discloses a silencer, which comprises multi-layer filter-mesh-shaped structures, an air inlet pipe, an air exhaust pipe and a cuboid casing, wherein the multi-layer filter-mesh-shaped structures are overlapped in the cuboid casing layer by layer, and each layer of the multi-layer filter-mesh-shaped structures is separated by a short partition plate. The position of one side of the casing corresponding to a bottom-layer filter-mesh-shaped structure is provided with the air inlet pipe provided with a flange, and the position of the other end of the casing corresponding to a top-layer filter-mesh-shaped structure is provided with the air exhaust pipe. The bottom surface of the casing is provided with two fixing seats parallel to each other. The silencer adopts the multi-layer filter-mesh-shaped structures which are overlapped layer by layer, and is compact in structure and good in silencing effect.

Description

A kind of silencing apparatus

Technical field

The utility model relates to the engine exhaust parts, particularly relates to a kind of silencing apparatus.

Background technique

During the motor combustion gas, the pressure of waste gas changes rapidly at the exhaust pipe mouth place, produces vibration, and vibration produces noise.In waste pipe, install silencing apparatus, be used to consume flowed energy, reduce the pressure surge amplitude of air-flow, can play the effect that reduces noise.In the existing silencing apparatus, it is big that air communication is crossed resistance, the exhaust back pressure height, and the engine power loss that causes is big, and oil consumption increases, and influences erasure effect; And most complex structure, volume is bigger than normal.

Summary of the invention

For overcoming above-mentioned shortcoming, the utility model proposes a kind of compact structure, the silencing apparatus of good muffling effect.

For achieving the above object, the technological scheme that the utility model proposes is: a kind of silencing apparatus comprises multistorey strainer mesh shape structure, suction tude, outlet pipe and a cuboid shell; Described multistorey strainer mesh shape construction layer is stacked to be placed in the cuboid shell, and each interlayer is separated by a breviseptum; This shell one end corresponds to bottom and filters cancellated position and be provided with a flanged (FLGD) suction tude, and the other end corresponds to top layer and filters cancellated position one outlet pipe is set, and its bottom surface is provided with two parallel fixed bases.

Further, described filter screen shape structure level number is more than or equal to 2 layers.

The beneficial effects of the utility model: this silencing apparatus uses stacked the putting of multistorey strainer mesh construction layer, compact structure, and erasure effect is good.

Description of drawings

Fig. 1 is the schematic perspective view of silencing apparatus of the present utility model;

Fig. 2 is the generalized section of silencing apparatus of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As illustrated in fig. 1 and 2, a kind of silencing apparatus of the present utility model comprises multistorey strainer mesh shape structure 2, suction tude 4, outlet pipe 5 and a cuboid shell 1; Described multistorey strainer mesh shape structure 2 is stacked and placed in the cuboid shell 1 layer by layer, and each interlayer is separated by a breviseptum 7; The position that these shell 1 one ends correspond to bottom filter screen shape structure 2 is provided with one flanged 3 suction tude 4, and the position that the other end corresponds to top layer filter screen shape structure 2 is provided with an outlet pipe 5, and its bottom surface is provided with two parallel fixed bases 6.

Air-flow enters the filter screen shape structure 2 that promptly enters bottom after the suction tude 4, is discharged to suction chamber by filter screen, is diffused into top layer through breviseptum 7 and the passage that shell 1 constitutes, and enters into top layer filter screen shape structure 2 after outlet pipe 5 is discharged through filter screen.Filter screen can reach good erasure effect layer by layer, form stacked layer by layer, compact structure.

Multistorey strainer mesh shape structure 2 can be two-layer or two-layer more than, separate by a breviseptum 7 between each layer.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; the various variations that the utility model is made are protection domain of the present utility model in the form and details.
