The purpose of this utility model is: a kind of a kind of silencer used for dust collector that provides is provided, and this device concentrates on one with multiple noise-reducing structure, be installed on the exhaust outlet of dust catcher after, can reduce the noise that dust catcher sends in use greatly.
The technical solution of the utility model is: a kind of silencer used for dust collector, this device comprises a closed shell, housing is provided with air intake and outlet air end, be provided with silencing cavity between air intake and the outlet air end, air intake and outlet air end are provided with air intake district and the wind outlet area of being made up of the pipe-like exhaust hole that gathers, and air intake sectional area and air-out sectional area are respectively less than the area of section of silencing cavity.
The further technical scheme of the utility model is: a kind of silencer used for dust collector, this device comprises a closed shell, housing is provided with air intake and outlet air end, be provided with silencing cavity between air intake and the outlet air end, air intake and outlet air end are provided with air intake district and the wind outlet area of being made up of the pipe-like exhaust hole that gathers, and air intake sectional area and air-out sectional area are respectively less than the area of section of silencing cavity; The air intake direction of described air intake district and wind outlet area can be identical with air-out direction, also can be angle.
The more detailed technical scheme of the utility model is: a kind of silencer used for dust collector, this device comprises a closed shell, housing is provided with air intake and outlet air end, be provided with silencing cavity between air intake and the outlet air end, air intake and outlet air end are provided with air intake district and the wind outlet area of being made up of the pipe-like exhaust hole that gathers, and air intake sectional area and air-out sectional area are respectively less than the area of section of silencing cavity; The air intake direction of described air intake district and wind outlet area can be identical with air-out direction, also can be angle; Stagger in air intake district and wind outlet area position on described air intake and the outlet air end; On the air intake that is set forth in and the outlet air end internal face zone beyond air intake district and wind outlet area be filled with the noise reduction cotton.
The utility model has the advantages that:
1. because air intake of the present utility model district and wind outlet area are made up of the pipe-like exhaust hole that gathers, can reduce the exhaust noise of dust catcher, and steam vent is more little, pipeline is long more, it is good more to reduce the effect of making an uproar.
2. between air intake and outlet air end, be provided with silencing cavity owing to the utility model, when the gas that the air intake district is entered enters silencing cavity, volume moment increase, thus can reduce noise.
3. the location arrangements of the utility model air intake district and wind outlet area staggers mutually, and the gas that the pipe-like exhaust hole in the air intake district is entered enters in the pipe-like exhaust hole that needs after the silencing cavity just can enter after the bending on the wind outlet area, thereby also can reduce noise.
4. the utility model zone beyond air intake district and wind outlet area on air intake and outlet air end internal face is filled with the noise reduction cotton, can reduce the exhaust noise of dust catcher equally.
5. above-mentioned four kinds of structures are combined on the utility model, and the sound-deadening and noise-reducing effect is strengthened greatly, after the utility model is installed on the exhaust outlet of dust catcher, can reduce the operating noise of dust catcher greatly.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is for being the stereogram of embodiment one;
Fig. 2 is the profile of embodiment one;
Fig. 3 is the stereogram of embodiment two;
Fig. 4 is the stereogram of embodiment three;
Wherein: 1 housing; 2 air intakes; 3 outlet air ends; 4 silencing cavity; 5 pipe-like exhaust holes; 6 air intake districts; 7 wind outlet areas; 8 noise reduction cottons.
The specific embodiment
Embodiment one: as Fig. 1, shown in Figure 2, a kind of silencer used for dust collector, this device comprises a closed shell (1), housing (1) is provided with air intake (2) and outlet air end (3), air intake (2) and outlet air end (3) lay respectively at the front-end and back-end of housing (1), the air intake direction is identical with air-out direction, be provided with silencing cavity (4) between air intake (2) and the outlet air end (3), air intake (2) and outlet air end (3) are provided with air intake district (6) and the wind outlet area of being made up of the pipe-like exhaust hole (5) that gathers (7), and air intake sectional area and air-out sectional area are respectively less than the area of section of silencing cavity (4); Air intake district (6) on the described air intake (2) be positioned at air intake (2) around, the inwall middle part of air intake (2) is embedded with noise reduction cotton (8), the wind outlet area (7) of described outlet air end (3) is positioned at the middle part of outlet air end (3), is embedded with noise reduction cotton (8) around the inwall of outlet air end (3).
Embodiment two: as shown in Figure 2, a kind of silencer used for dust collector, this device comprises a closed shell (1), housing (1) is provided with air intake (2) and outlet air end (3), air intake (2) and outlet air end (3) lay respectively at the front end and the side of housing (1), air intake direction and air-out direction have angle, be provided with silencing cavity (4) between air intake (2) and the outlet air end (3), air intake (2) and outlet air end (3) are provided with air intake district (6) and the wind outlet area of being made up of the pipe-like exhaust hole (5) that gathers (7), and air intake sectional area and air-out sectional area are respectively less than the area of section of silencing cavity (4).
