Description

A kind of grating type pipeline silencer
Technical field
The utility model relates to silencing apparatus technical field, specifically refers to a kind of grating type pipeline silencer.
Background technique
Pipe ventilated silencing apparatus is usually used in heating ventilation class engineering, as subway tunnel ventilation system, Central Air Conditioner Used in Buildings ventilation system, machine room heat dissipation ventilation system etc., its objective is under the prerequisite guaranteeing air-conditioning requirement, the impact of abatement apparatus Noise upon Environment.Pipe ventilated silencing apparatus is generally installed in ventilation duct, can be installed on the positions such as intake grill, exhaust port, air outlet.When adopting the mechanical ventilation equipments such as large fan in ventilation system, can produce very large noise, noise is propagated outward by ventilation duct, can cause pollution from environmental noise to relevant position or region, particularly tuyere position indoor or close residential belt, its influence of noise is particularly serious.In modern city and industrial development, pipe ventilated silencing apparatus is absolutely necessary industrial products, uses very general.
The acoustical behavior of silencing apparatus and aerodynamic quality, depend on the factors such as the effective length of the cross-section size of the internal structure of the acoustical behavior of acoustics filler, anechoic sheet, air-flow path, airspeed and silencing apparatus.Major parameter has insertion loss, reproduced air-flow noise, the pressure loss etc.
At present, mostly what market was applied is integrated type silencing apparatus, and need overall carrying, integral hoisting, installation difficulty is large, is not suitable for large-scale ventilation system.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of grating type pipeline silencer, and this silencing apparatus sound-adsorbing sound-insulating hung performance is better, and installation and removal efficiency is high, facilitates plant maintenance and maintenance.
For solving the problems of the technologies described above, model utility by the following technical solutions:
A kind of grating type pipeline silencer, comprise conduit enclosure, described conduit enclosure is assembled by muffler plate, anechoic sheet is provided with in conduit enclosure, anechoic sheet is plank frame, and crisscross splicing is connected in conduit enclosure, in muffler plate and anechoic sheet, be equipped with sound-adsorbing sound-insulating hung material, muffler plate inside and anechoic sheet sidewall are equipped with sound-absorption hole.
Preferably, above-mentioned muffler plate and anechoic sheet are galvanized steel plain sheet, corrosion resistant plate or aluminium sheet.
The beneficial effects of the utility model are:
The utility model grating type pipeline silencer features simple structure, reasonable in design, cost is low, modularization assembling, adopt said structure, for the carrying of product and installation provide convenient, facilitate the maintenance repair of staff, and, vent area equal in length is identical, absorption area is larger, soundproof effect is better, and air distribution is smooth and easy, can meet higher noise elimination requirement with shorter length, be applicable to all kinds of medium-sized and large-scale ventilation air duct system, should be widely promoted use.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model spacing grid type pipeline silencer perspective view;
Accompanying drawing 2 is another spacing grid type pipeline silencer perspective view of the utility model.
Embodiment
Model utility to be explained in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
As shown in accompanying drawing 1-2, a kind of grating type pipeline silencer, comprise conduit enclosure 1, conduit enclosure 1 is assembled by muffler plate, in conduit enclosure 1, be provided with anechoic sheet 2, anechoic sheet 2 is plank frame, and crisscross splicing is connected in conduit enclosure 1, its structure shape is intersecting parallels, and the spacing between the thickness of anechoic sheet 2, length and anechoic sheet 2 is selected according to noise elimination requirement.Sound-adsorbing sound-insulating hung material is equipped with in muffler plate and anechoic sheet 2, muffler plate inside and anechoic sheet 2 sidewall are equipped with sound-absorption hole, water proof and dust proof encapsulation process made by the sound-absorbing material of sound-adsorbing sound-insulating hung material, guarantee that sound-absorbing material does not escape, maintain the physical state that sound-absorbing material is good, sound insulating material can select highdensity centrifugally glass-wool, and glass wool decrement is 5%; Sound-absorption hole aperture is Ф 2.5mm, and sound-absorption hole spacing is 5.0mm, and sound-absorption hole is equilateral triangle arrangement, and punching rate is set to 23%.In order to meet the usage requirement of multiple occasion, the proportioning of different sound insulating materials and sound-absorbing material can be adopted to combine.
In the present embodiment, conduit enclosure 1 is assembled by muffler plate, and anechoic sheet 2 is plank frame, and crisscross splicing is connected in conduit enclosure 1, thus making this pipeline silencer adopt modular sheet material to combine, assembling, removal efficiency is very high, greatly facilitates maintenance and the maintenance of silencing apparatus.
In addition, muffler plate and anechoic sheet 2 can select galvanized steel plain sheet, corrosion resistant plate or aluminium sheet, the process such as can carry out spraying paint in muffler plate and anechoic sheet 2 surface, powder spray, play the antirust and decoration functions of silencing apparatus.
During the assembling of the utility model grating type pipeline silencer, pipeline silencer two ends can be connected with ventilation duct by mounting flange, gas is through this grating type pipeline silencer, noise is absorbed by sound-absorbing material by sound-absorption hole, and intercepted by sound insulating material, substantially reduce noise and spread out of outside, cause noise pollution, equal in length, when vent area is identical, absorption area is larger, soundproof effect is better, air distribution is smooth and easy, higher noise elimination requirement can be met with shorter length, be applicable to all kinds of medium-sized and large-scale ventilation air duct system, should be widely promoted use.Because sound-adsorbing sound-insulating hung material is that market is common, be not described in detail at this.
Above-described embodiment is the preferred version that the utility model realizes, and indefiniteness is exhaustive, and under same idea, the utility model can also have other variations.It should be noted that, under the prerequisite not departing from the present utility model design, any apparent replacement is all within the utility model protection domain.
