Net.
Implement above-mentioned technical proposal, the setting of filter screen reduces dust or impurity enters the generation of the phenomenon in cavity.
Further, the filter screen includes frame and grenadine, and the company being detachably connected with wall is provided on the frame
Fitting, the connector include bolt and threaded sleeve, and the threaded sleeve is embedded on wall, and the bolt-through frame is set
It sets and one end is threadedly coupled with threaded sleeve.
Implement above-mentioned technical proposal, filter screen and wall are detachably connected so that the mesh on filter screen is by dust and impurity
Removable unload down of filter screen is cleaned and is replaced when blocking.
Further, the dust block board for entering air inlet or air outlet for reducing dust, the gear are provided on the wall
Hawk is set as two, and a dust block board is arranged above air inlet, another dust block board is arranged above air outlet.
Implement above-mentioned technical proposal, the setting of dust block board, which reduces the dust above air inlet or air outlet and falls, is filtering
Online phenomenon occurs, and reduces the blocked phenomenon of the mesh on filter screen and occurs.
Further, the dust block board is obliquely installed and inclined higher-end and wall connecting.
Implement above-mentioned technical proposal, the impurity fallen on dust block board rolls eventually off gear along the inclined side wall of dust block board
Hawk, dust block board are obliquely installed the adhesion amount for reducing dust and impurity on dust block board.
In conclusion the utility model has the following beneficial effects:
One, the setting of soundproof plate is so that sound wave reaches the path at air outlet and increases, so that sound wave is sprung back between soundproof plate
It is absorbed by the sound-absorbing cotton piece in cavity;
Two, the setting of filter screen reduces dust or impurity enters the generation of the phenomenon in cavity.

Specific embodiment
Below in conjunction with attached drawing, the technical solution of the utility model embodiment is described.
Embodiment:
As shown in Figure 1, a kind of sound insulation ventilation wall, including wall 1, the wall 1 are internally provided with cavity 11, cavity 11 is leaned on
The extraneous air inlet 12 of connection is offered on nearly outdoor side wall, and air inlet 12 is arranged close to ground.Cavity 11 is close to indoor
Side wall on offer the indoor air outlet 13 of connection and air outlet 13 is arranged far from ground.
As shown in Figure 1, 2, air inlet 12 and air outlet 13 far from one end of cavity 11 be provided with closing air inlet 12 or
The filter screen 4 of air outlet 13, filter screen 4 include frame 41 and grenadine 42, are provided on the frame 41 and detachably connect with wall 1
The connector 5 connect, the connector 5 include the threaded sleeve 52 being embedded on wall 1 and are threadedly coupled with threaded sleeve 52
Bolt 51, the bolt 51 run through frame 41.Rotating bolt 51 can dismantle filter screen 4, facilitate operator to mistake
The cleaning and replacement of strainer 4.
As shown in Figure 1, the top of air inlet 12 and air outlet 13 is provided with inclined dust block board 6, the higher-end of dust block board 6
It is connect with wall 1.Dust block board 6 is obliquely installed so that the impurity fallen on dust block board 6 rolls most along the inclined side wall of dust block board 6
Dust block board 6 is left eventually, reduces the adhesion amount of dust and impurity on dust block board 6.
As shown in Figure 1, being provided with sound-absorbing cotton piece 2 and soundproof plate 3 on the side wall of the cavity 11, the soundproof plate 3 is set
Set between the soundproof plate 3 adjacent thereto of the free end for opening up the side wall of air inlet 12 and air outlet 13 and soundproof plate 3 that there are gaps.
Soundproof plate 3 is obliquely installed and inclined lower end is connect with 11 side wall of cavity, and the soundproof plate 3 on different lateral is arranged in vertical
11 bottom wall of cavity is blocked in projection on direction.Soundproof plate 3 is made of acoustical cotton in the present embodiment.The setting of soundproof plate 3 is so that sound
Wave reaches the path at air outlet 13 and increases, and is absorbed so that sound wave is sprung back between soundproof plate 3 by the sound-absorbing cotton piece 2 in cavity 11,
Reduce the phenomenon that noise enters the room.
The process of ventilation: the gas in cavity 11 at air inlet 12 is contacted with ambient atmos, and under the action of heat exchange
It is gradually warmed up, since the temperature of the gas in cavity 11 is lower than the temperature of ambient atmos, in cavity 11 on the higher gas of temperature
It rises, the gap between soundproof plate 3 simultaneously enters the room from air outlet 13.Because of the factor of draught head, the higher gas of outdoor temperature
Body enters in cavity 11 from air inlet 12, rises enter the room from air outlet 13 again, finally gradually form siphonic effect, make
It obtains outdoor gas and is constantly transported to indoor completion ventilation process.
Noise reduction process: noise enters from air inlet 12 in cavity 11, and partial noise is absorbed by sound-absorbing cotton piece 2, partially makes an uproar
The sound wave of sound is sprung back between soundproof plate 3, is absorbed when recoiling at sound-absorbing cotton piece 2 by sound-absorbing cotton piece 2, reduces noise from air outlet
It is entered the room at 13.
