Abstract
The utility model discloses a silencing shade presenting a box type, which is composed of a hard sound-absorbing plate and a soft sound-absorbing plate which are combined; an air-in silencing channel is arranged in a box body; two soft sound-absorbing plates for closing the opening of the box body are arranged at the neck position of the outlet of a burner. The utility model which adopts an assembly type structure is provided with the special-purpose air-in silencing channel; the two soft sound-absorbing plates with notches are arranged at the neck position of the outlet of the burner; magnetic materials are filled at the periphery of the sound-absorbing plates; the two soft sound-absorbing plates and a whole plane are sucked together. The utility model has the advantages of good sealing effect, no leakage, convenient assembly and good silencing effect.
Description
Technical field
The utility model relates to a kind of sound arrester that disappears, especially a kind of acoustic hood that disappears that is applicable to fuel oil (gas) boiler-burner.
Background technology
Along with people's improving constantly to environmental protection consciousness; in order to improve air quality; fuel oil (gas) boiler has progressively replaced coal-burning type boiler; and during fuel oil (gas) boiler combustion; the dry sound pitch that burner produced reaches 80-90dB; seriously pollute environment, affected operating personnel and peripheral resident's physical and mental health. in order to reduce noise, the easiest method adds a sound proof housing to oil burner exactly.Sound proof housing as patent No. ZL01217459.9, because this technology has only adopted four wallboards that have sound-absorbing material to combine, and during burner combustion, the air inlet of burner bottom is wanted a large amount of air of inspiration, this technology does not have special-purpose air inlet, air can only suck from the one side of opening, and the one side of opening does not have soundproof measures fully, add as ground, boiler room injustice, reveal for producing noise on shirt rim that seals and ground, thereby influenced the noise elimination effect. and as increasing the noise elimination effect, also needing increases the air intake silencer at air inlet, supporting use, so just the maintenance to burner has brought inconvenience.
Summary of the invention
The utility model is to overcome the defective that existing sound proof housing exists, and provides a kind of sealing tight, and air intake is eliminated the noise and the whole sound proof housing of eliminating the noise and being integrated.
For achieving the above object, the utility model is achieved in that a kind of sound proof housing, is box, is combined by hard and soft abatvoix.In casing, be provided with an air intake noise elimination road, the two block soft abatvoixs airtight with box mouth are installed at burner outlet neck place.
Air intake noise elimination road is to be made of air intake breach and air inlet abatvoix, wherein the air intake breach is arranged on the casing abatvoix, place the air inlet abatvoix below the air intake breach, the air inlet abatvoix is close to positive side draught soundboard and left side plate and is tightly connected, and leaves a breach between header board.
Two blocks of soft abatvoixs respectively are equipped with magnetic material on its surrounding edge, between two blocks of soft abatvoixs and and the casing actinal surface between adhesive sealing.
The utility model is owing to adopt modular construction, be provided with special-purpose air intake noise elimination passage, the burner outlet neck, adopt two blocks of soft abatvoixs that have breach, around the abatvoix magnetic material be housed, can two between and be pull-in on one with whole plane, good sealing effect, do not have and reveal, easy to assembly, the noise elimination effect is remarkable.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is the right cutaway view of Fig. 1;
Fig. 3 is the schematic diagram behind the soft abatvoix of removal.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As Fig. 1, shown in 2,3, sound proof housing is by top abatvoix 3, positive side draught soundboard 5, and six blocks of hard abatvoixs such as left and right sides abatvoix 6 grades and two blocks of soft abatvoixs 1 are assembled into box sound proof housing.Four universal wheels 8 are installed below the end abatvoix, are used for mobile sound proof housing.
In casing, below the top abatvoix 3, there is an air intake noise elimination road 10 the blower fan top, and air intake noise elimination road 10 is to be made of air intake breach 9 and air inlet abatvoix 4.Above the positive side draught soundboard 5 of casing, have an air intake breach 9, air intake breach 9 also can be located on the top abatvoix 3, one air inlet abatvoix 4 is installed below the air intake breach 9 in casing, air intake abatvoix 4 is close to positive side draught soundboard 5 and left and right sides sound-absorbing side plate 6 and is sealedly and fixedly connected, and and front panel between leave a breach 11.During burner combustion, the air inlet of burner bottom just can be by the air intake a large amount of air of 10 inspirations of eliminating the noise, and air intake noise elimination road 10 can play again and eliminate the noise and the effect of sound insulation simultaneously.
The burner outlet neck adopts two blocks of soft abatvoixs 1 that have breach, around the abatvoix 1 magnetic material 2 is housed, and can make between two blocks of soft abatvoixs 1 and with whole plane and be pull-in on one, and good sealing effect does not have and reveals, and easy to assembly, it is effective to eliminate the noise.
Claims (3)
1. a sound proof housing is box, is combined by hard and soft abatvoix, it is characterized in that, is provided with an air intake noise elimination road (10) in casing, and the two block soft abatvoixs (1) airtight with box mouth are installed at burner outlet neck place.
2. sound proof housing according to claim 1, it is characterized in that, described air intake noise elimination road (10) is to be made of air intake breach (9) and air inlet abatvoix (4), wherein air intake breach (9) is arranged on casing abatvoix (3) or (5), place air inlet abatvoix (4) below the air intake breach (9), air inlet abatvoix (4) is close to abatvoix (5) and left and right sides abatvoix (6) and is tightly connected, and leaves a breach (11) between header board.
3. sound proof housing according to claim 1 is characterized in that, described two blocks of soft abatvoixs (1) respectively are equipped with magnetic material (2) on its surrounding edge, between two blocks of soft abatvoixs (1) and and the casing actinal surface between adhesive sealing.
