Abstract
The utility model relates to a muffler device for a diesel generator, comprising a housing and at least two perforated pipes arranged in the housing. An air inlet and an air outlet are arranged at the two adjacent lateral faces of the housing respectively, and sound absorption material is arranged on the medial wall of the housing. The utility model is characterized in that a cleaning hole and a disassembly sealing cover are arranged at the lower end of the housing, and the sealing cover at the lower end of the cleaning hole is arranged on the outer flank of the housing and seals the cleaning hole. Compared with the prior art, the utility model has the advantages of effectively reducing noise, prolonging service time of the muffler device, cleaning the housing without disassembling, greatly reducing the production cost, greatly saving manpower and material resources, improving the productivity, and facilitating the operation with simple structure due to the cleaning hole and the sealing cover.
Description
Technical field
The utility model relates to a kind of silencer of diesel generator.
Background technique
The silencer of existing diesel generator, its structure is housing, and housing is provided with suction port, relief opening, and suction port, relief opening be located at respectively on the adjacent sidewall, is provided with a plurality of perforated tubes in the housing, and inner walls is provided with sound-absorbing material.
As Chinese patent literature CN2357134 " exhaust Muffler of Diesel Powered Generator ", a kind of exhaust Muffler of Diesel Powered Generator is disclosed, its shell is that cylindrical two ends are the spherical crown shape, shell is provided with suction port, relief opening, in be provided with the labyrinth, be provided with the wave filter that perforated pipe is formed in the enclosure, outer casing inner wall is provided with sound-absorbing material.
But the silencer of this structure will gather volume of smoke because of inside after using a period of time, cause silencer ineffective.The user has only replacing or silencer is dismantled lower casing clean, and has therefore significantly increased cost of production, has consumed lot of manpower and material resources, has reduced manufacturing efficiency, uses very inconvenient.
Summary of the invention
The purpose of this utility model is that prior art is improved, a kind of silencer of diesel generator is provided, can effectively guarantees to reduce the effect of noise, and can significantly prolong the service time of silencer, need not often to dismantle shell and clean, the technological scheme of employing is as follows:
The silencer of diesel generator of the present utility model, comprise housing and at least two perforated tubes that are located in the housing, be respectively equipped with suction port and air outlet on two adjacent side on the housing, the housing madial wall is provided with sound-absorbing material, it is characterized in that: described housing lower end is provided with lancing door and dismountable sealing cover, sealing cover is installed in hull outside, and is positioned at the lancing door lower end, seals lancing door.In the time of proper functioning, because sealing cover seals lancing door, therefore, the gas of the discharge of diesel generator enters from suction port, enters in the housing by perforated tube, through the effect of sound-absorbing material, discharges from the air outlet by perforated tube again.After long-term work, a large amount of flue dust is collected in the housing, and the user can pull down sealing cover, and flue dust is discharged, and installs sealing cover again, just can continue to use.
The utility model beneficial effect against existing technologies is, owing to be provided with lancing door and sealing cover, therefore can effectively guarantee to reduce the effect of noise, and can significantly prolong service time of silencer, and need not to dismantle shell and clean, significantly reduced cost of production, need not to have consumed lot of manpower and material resources, improved manufacturing efficiency, very easy to use, it is simple in structure, be easy to realize.
Description of drawings
Accompanying drawing is the structural representation of the utility model preferred embodiment.
Embodiment
As shown in drawings, the silencer of the diesel generator in this preferred embodiment, comprise housing 1 and two perforated tubes 2,3 that are located in the housing, be respectively equipped with suction port 4 and air outlet 5 on two adjacent side on the housing, housing 1 madial wall is provided with sound-absorbing material 6, and described housing 1 lower end is provided with lancing door 7 and dismountable sealing cover 8, and sealing cover 8 is installed in housing 1 outside, and be positioned at lancing door 7 lower ends, lancing door is sealed.
In the time of proper functioning, because sealing cover 8 is with lancing door 7 sealings.Therefore, the gas of the discharge of diesel generator enters from suction port 4, enters in the housing 1 by perforated tube 2, through the effect of sound-absorbing material 6, again by perforated tube 35 discharges from the air outlet.After long-term work, a large amount of flue dust is collected in the housing 1, and the user can pull down sealing cover 8, and flue dust is discharged, and installs sealing cover 8 again, just can continue to use.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
