Description
Technical field
The present invention relates to a kind of fixed closing device, relate in particular to a kind of ventilation equipment relevant with door and window.
Background technology
A lot of places or workshop require very high to the ventilation effect of blind door and window, as dancing hall, machine shop, chemical workshop, processing of stone etc., generally speaking, the workshop temperature can reach more than 40 degree, that have even to 80 degree, can't operate as normal under this environment, heat radiation becomes the problem of primary solution.Existing radiating mode is natural ventilation, promptly carries out interchange of heat by blind door and window and outdoor air, though can dispel the heat effectively by blind door and window, a large amount of noises also passes to outdoor through blind door and window, causes noise pollution.So a kind ofly both can prevent dust, noiseproof, the device that can breathe freely becomes people's first-selection again.
On February 23rd, 2005 disclosed Chinese patent application, publication number is CN1584976A, it discloses a kind of shutter of eliminating the noise laminated material and making, comprise metal sheet, centrifugally glass-wool, also disclose a kind of laminated material of eliminating the noise and curved the noise elimination louvre blade that the bridge shape is made, it comprises par and turn of bilge, and this device can abate the noise preferably, but its gas permeability is bad; And want to change the length that gas permeability must shorten blade, its antinoise performance is bad again like this.So abate the noise with to increase gas permeability be implacable contradiction.
Summary of the invention
Effect of the present invention can overcome above-mentioned defective, and a kind of blind door and window that not only can effectively prevent noise but also have fine gas permeability is provided.
For achieving the above object, the present invention adopts following technical scheme: it comprises framework and sound absorption air-permeable layer, and the sound absorption air-permeable layer is fixed in the framework, and the sound absorption air-permeable layer comprises absorbent treatment and ventilation stack, is provided with ventilation stack between the adjacent absorbent treatment, and ventilation stack adopts curve form.
The sound absorption air-permeable layer is provided with two-layer, adjacent sound absorption air-permeable layer at least and fixes as one, and a plurality of air-permeable layer combine and can reduce noise better; For ventilating better, exhaust fan can be installed on shutter, carry out forced ventilation.Ventilation stack can adopt multiple curve form: as adopt the form of sine or cosine curve, the form of employing square-wave curve, the form of employing sawtooth curve etc., can also be used in combination by multiple curve.Be provided with the glass silk flosssilk wadding in the absorbent treatment, can reach good sound-absorbing effect.The bending place of ventilation stack is provided with sound-absorption hole or groove on absorbent treatment, be provided with the resistance soundboard of arc at sound-absorption hole or groove periphery, can improve sound-absorbing effect greatly with the more noise wave absorption in sound-absorption hole or groove like this.When sound wave sees through sound-absorption hole or groove and enters in the glass silk flosssilk wadding, there is quite a few acoustic energy to convert heat energy to, discharge outdoorly with air, further reached the effect that reduces noise.The bending height of curve is higher than the climbing height of raindrop, can effectively prevent entering of rainwater like this, has rainproof effect.
Framework comprises frame cover and framework, and the frame cover is connected with the dual-side of framework; Frame puts and is provided with draw-in groove or Ka Tai, and the frame cover on each framework adopts two usually, and a frame puts draw-in groove is set therein, and another frame puts Ka Tai must be set, and the frame that draw-in groove and Ka Tai promptly are set overlaps supporting use; The both sides of framework are respectively equipped with channelling and boss, channelling is positioned on the opposite side of framework with boss and also can be arranged on the same side, a plurality of like this frameworks can be cascaded, be about to the channelling of one of them framework and the boss strings of another framework and be connected together, have good fastness; The central authorities of framework are provided with fixing hole, adopt screw that framework is fixed on the absorbent treatment usually.Because frame puts and is provided with draw-in groove or Ka Tai, the frame cover that like this one of them is provided with draw-in groove is enclosed within on the boss of framework, and the frame cover string that Ka Tai is set can be formed complete framework on the channelling of framework.Width according to user's needs framework can be regulated arbitrarily, only needs according to circumstances a plurality of frameworks series connection to be used get final product; If frame width needs smaller adjusting, only need with framework the draw-in groove that overlaps of channelling and boss and frame or Ka Tai finely tune and get final product, promptly can only the part channelling of framework and the part draw-in groove or the Ka Tai of boss or frame cover be fastened, reach the width that needs and get final product.
This device can reduce the pollution that noise brings effectively, and has good permeability, and has rainproof effect, can be widely used in technical fields such as door and window.
