3, adopt products such as sound-proof and ventilating window that basic structure of the present utility model is made, sound insulation vent window, noise reduction dedusting vent window, the ventilative unit box of noise reduction, be fit to be applied to the demand sound insulation of both sides, major urban arterial highway road also needs ensure the user of ventilation.Preferably resolve indoor ventilating problem, greatly reduce the noise pollution of external environment producing in the room.Be specially adapted to life, workplaces such as near the dwelling house of elevated road, the main line of communication, lively fairground or industrial enterprise, hospital, school, can effectively improve people's living environment quality.
Description of drawings
The utility model has three accompanying drawings, wherein:
Accompanying drawing 1 is a kind of structure mounting arrangement figure of sound-proof and ventilating dust arrester;
Accompanying drawing 3 accompanying drawings 2 overlook horizontal cross-section structure.
Among the figure: 1 dust-separation screen window, 2 venetian blind types open and close plate, 3 sound insulation bar batten assemblys, 4 unit bar battens, the vertical section of 4.1 unit bar battens, the horizontal section of 4.2 unit bar battens, the indoor quiet new wind of A---, B---outdoor noise field.
The specific embodiment
The specific embodiment of the present utility model as shown in drawings, opening and closing plate 2 by dust-separation screen window 1, venetian blind type is formed, it is characterized in that: open and close the plate 2 middle sound insulation bar batten assemblys 3 that are equipped with at dust-separation screen window 1 and venetian blind type, sound insulation bar batten assembly 3 is made up of one group of unit bar batten 4, all has the gap that the air communication of guaranteeing is crossed between each unit bar batten 4, each unit bar batten 4 multi-layer intercrossed formula constitutes the chamber, labyrinth, and each unit bar batten 4 right angle launches face orientation to outdoor noise field B.The unit bar batten 4 that sound insulation bar batten assembly 3 is arranged by multi-layer intercrossed formula is formed, and the section configuration of described each grizzly bar is rectangular in shape, and the right angle face formula of intermeshing of multilayer grizzly bar is arranged, the concave surface of right angle type over against the noise sound wave come to.Unit bar batten (4) has 6 rows, and the quantity of every row unit bar batten 4 is 5.The open-work that has 16 row＜shapes on the vertical section 4.1 of unit bar batten; The quantity of＜shape open-work is 96.Each independently between the unit bar batten (4) all at a distance of the distance of 6mm.
Operating principle of the present utility model: usually, sound wave has the characteristics of straightline propagation in air; And the right angle mask has the characteristics of vertical reflection.Basic structure of the present utility model is utilized above-mentioned basic principle exactly, utilize the right angle of each grizzly bar effectively to reflect earlier in the face of outdoor noise sound wave, utilize multi-layer intercrossed formula to constitute the chamber, labyrinth again the noise sound wave that enters is effectively reflected decay, so insulating noise effectively.This basic structure utilization is simultaneously carried out multi-layer intercrossed formula to grizzly bar and is arranged and constitute the chamber, labyrinth, can carry out turbulent flow to the air-flow that enters, form multiple vortical flow, make the dust of grain greatly in the air-flow that enters to lose kinetic energy and hang, so have certain dedusting function.This basic structure again because of relatively independent between the grizzly bar, all at a distance of certain distance, for the air-flow that enters stays complications but unobstructed relatively wind path, does not enter passing through of air-flow so do not influence, so can keep ventilation function between each grizzly bar simultaneously.The grizzly bar that basic structure of the present utility model is arranged by multi-layer intercrossed formula is formed, and the section configuration of described each grizzly bar is rectangular in shape, and the right angle face formula of intermeshing of multilayer grizzly bar is arranged, the concave surface of right angle type over against the noise sound wave come to.The surface of grizzly bar can be a smooth surface, also can be attached with sound absorption materials such as felt, sound absorption cotton.The outdoor face of sound-proof and ventilating dust arrester can be provided with nylon or steel wire window screening, stops that leaf or winged insect etc. enter ventilation opening.The chamber internal surface of sound-proof and ventilating dust arrester can be provided with venetian blind type and open and close plate, supplies opened manually or closes ventilation opening.The sound-proof and ventilating dust arrester can add ventilation fan, and by the blower fan forced convection, it is more unobstructed that indoor-outdoor air is exchanged, and guarantees effectively sound insulation, ventilation under the various weather conditions.Adopt products such as sound-proof and ventilating window that basic structure of the present utility model is made, sound insulation vent window, noise reduction dedusting vent window, the ventilative unit box of noise reduction, be installed on room and the outdoor wall or window that links to each other, can make the room under the situation that window is closed, still keep good sound insulation ventilation effect, make outdoor fresh air enter the room.
