Abstract
The utility model provides a window type ventilation silencer, comprising a centrifugal fan (2), a filter screen (3) and a sound absorption material (8). The indoor air enters from an air inlet and flows to a lower right cavity (7) through an upper right cavity (6). The duct in the air is filtered through the filter screen (3), and then is transmitted to a left cavity (9). The centrifugal fan (2) down exhausts the air to the ouside from an air outlet (11). Cooperated with a sound proof window, the uility model has the efficacies of sound proof and ventilation guarantee. The window type ventilation silencer is suitable for users of residences, office buildings, schools and hospitals at both sides of city main roads and elevated roads.
Description
Technical field
The utility model relates to the ventilation installation that a kind of building is used, particularly with the matching used ventilation installation of sound proof window.
Background technology
The traffic noise of major urban arterial highway road and viaduct is serious day by day at present, the people that are positioned at these highway sections bear serious noise, people have to close the doors and windows to reduce the interference of noise, but so brought the room ventilation problem, along with the performance of existing market soundproof door, window is constantly improved, the ventilation installation that matches with soundproof door, window that market demand is not only ventilated but also can be eliminated the noise reduces the circulation of noise jamming assurance room air to satisfy when closing the doors and windows.Gong Ying ventilation silencer structure is complicated in the market, and it is not too convenient to install.
Summary of the invention
The purpose of this utility model provides a kind of good looking appearance, and is simple and practical, adopts the mechanical ventilation form, reaches the ventilation installation that not only ventilates but also insulate against sound.Window formula ventilation silencer mainly is existing aluminum window of cooperation or soundproof door, ensures when window is realized reducing noise jamming that room air circulates.
The purpose of this utility model is achieved in that window formula ventilation silencer comprises casing (1), centrifugal fan (2), screen pack (3), sound absorption material (8) composition.Longitudinal baffle (4) is separated into left and right two cavitys with casing (1), and lateral partitions (5) is divided into upper right cavity (6) and bottom right cavity (7) with right cavity, and centrifugal fan (2) is installed in left cavity (9), pastes sound absorption material (8) around casing (1) inwall.Room air enters from air inlet port (10), changes bottom right cavity (7) over to through upper right cavity (6), through flowing to left cavity (9) behind filter screen (3) Chalk-dust filtering, discharges outdoor by centrifugal fan (2) downwards from air outlet (11) at last.The outdoor noise that enters air outlet (11) is absorbed by the sound absorption material of left cavity (9), bottom right cavity (7) and upper right cavity (6), and noise acoustic energy is reached the purpose of noise elimination by effective attenuation.
Description of drawings
Fig. 1 is the utility model application example schematic diagram.
Fig. 2 is the A-A sectional view of Fig. 1.
In Fig. 1～2,1. casing, 2. centrifugal fan, 3. screen pack, 4. longitudinal baffle, 5. lateral partitions, 6. upper right cavity, 7. bottom right cavity, 8. sound absorption material, 9. left cavity, 10. air inlet port, 11. exhaust openings, gravity vent about in the of 12., 13. left and right sides gravity vents.
The specific embodiment
In conjunction with the accompanying drawings 1,2 and embodiment the utility model is described in further detail.Window formula ventilation silencer overall fixed is on body of wall, and the outer body of wall that stretches out of casing (1) partly supports with angle-iron frame.Casing (1) material is galvanized iron sheet or fiber cement increased pressure board (FC plate).Cabinet wall pastes sound absorption material (8), and sound absorption material is mineral wool sound absorption board or foam sponge.By longitudinal baffle (4) and lateral partitions (5) casing (1) inner chamber is separated into upper right cavity (6), bottom right cavity (7) and left cavity (9), centrifugal fan (2) is installed in the left cavity (9).Because the negative pressure that centrifugal fan (2) is produced makes room air suck from air inlet port (10), enter upper right cavity (6), flow to bottom right cavity (7) by gravity vent (12) up and down, on longitudinal baffle (4), have left and right sides gravity vent (13), screen pack (3) is installed on left and right sides gravity vent (13), air communication enters left cavity (9) after crossing screen pack (3) remove dust, discharges outdoor by exhaust opening (11) under the centrifugal fan effect.The external noise that enters in the casing (1) is decayed by the sound absorption material in the labyrinth type air channel of being made up of left cavity (9), bottom right cavity (7), upper right cavity (6), reaches the purpose of noise elimination.
Claims (3)
1. window formula ventilation silencer, comprise casing (1), centrifugal fan (2), screen pack (3) composition, it is characterized in that longitudinal baffle (4) is separated into left and right two cavitys with casing (1), lateral partitions (5) is divided into upper right cavity (6) and bottom right cavity (7) with right cavity, pastes sound absorption material (8) around casing (1) inwall.
2. by the described window formula of claim 1 ventilation silencer, it is characterized in that centrifugal fan (2) is positioned at left cavity (9), room air enters from air inlet port (10), flow to bottom right cavity (7) through upper right cavity (6), go to left cavity (9) through filter screen (3), discharge outdoor from exhaust opening (11) by centrifugal fan (2).
3. by the described window formula of claim 1 ventilation silencer, it is characterized in that casing (1) inwall subsides all around sound absorption material (8), sound absorption material (8) is mineral wool sound absorption board or foam sponge.
