Abstract
The utility model belongs to the technical field of environment protection and particularly relates to a ventilator silencer. The ventilator silencer comprises a ventilator silencer body, wherein an outlet is formed in the upper part of the body; an inlet is formed in the lower part of the body; a resistant shell, a dust-cleaning door, a rubber compressing bar and a rain-proof cap are also arranged on the shell; the dust-cleaning door is arranged on the resistant shell; the rubber compressing bar is arranged between the dust-cleaning door and the resistant shell; and the rain-proof cap is arranged at the upper end of the outlet of the body. The silencer is arranged at a ventilating outlet of a large fan, stable in running and stable in noise-reducing effect, and the requirement on designed noise reduction is kept.
Description
Technical field
The utility model belongs to environmental technology field, relates in particular to a kind of silencing apparatus of ventilator noise reduction.
Background technique
In a lot of chemical industry, cement product, grain are raised the production process of the industries such as processing, all to use ventilator and carry out mass transport, dust discharge and ventilation, clean operational site.Due to the restriction of the condition of ventilator own, the change due to air-flow during blower fan work produces powerful pneumatic noise.Because its medium is air-flow, and the blower fan place in these industries, basically all with tiny dust.This is for technological difficulties in ventilator reduction noise, and silencing apparatus has been installed according to environmental requirement by a lot of enterprises, but after a period of time, silencer internal wall has sticked dust, lost its original effect, and the airflow obstruction impact of conveying is produced, reduce manufacturing efficiency and quality of product.
At present, domestic silencing apparatus manufacturing enterprise is a lot, and kind is also a lot, and main in process of production what consider is the noise reduction of silencing apparatus, and its structure designs according to this principle.Because the noise-cancelling theory of silencing apparatus is that sound wave enters the sound-absorbing material of silencing apparatus inner chamber by the hole of silencer internal wall, sound wave constantly compresses to loosen has flexible material, reaches reduction sound thereby change energy.After the hole of the perforated plate of silencer internal wall is sticked by dust, sound wave can't be entered in sound-absorbing material in the chamber go, naturally just lost the effect of noise reduction.Therefore, eliminating the dust that sticks to silencer internal wall, keep the effect of noise elimination, extend the working life of silencing apparatus, is problem needing to overcome.
Summary of the invention
Technical problem to be solved in the utility model is to provide the ventilator silencing apparatus that a kind of soundproof effect is better, increase working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of ventilator silencing apparatus, comprise the ventilator muffler body, the top of described body is provided with outlet, the bottom of described body is provided with import, also be provided with resistance housing, deashing door, rubber press strip and rainhat on described body, described deashing door is installed on the resistance housing, and described rubber press strip is arranged between described deashing door and described resistance housing, and described rainhat is arranged at body and exports the upper end.
As the further optimization of technique scheme, be connected through the hinge between described deashing door and resistance housing, described hinge comprises fastener and fixing bolt.
At impedance complex formula silencing apparatus, resistance is partly installed deashing door.
Deashing door and silencing apparatus resistance partial shell are installed the rubber press strip.
Deashing door is connected hinge, fastener, bolt to be fixed with silencing apparatus resistance housing, detachable during deashing.
The beneficial effect main manifestations of a kind of ventilator silencing apparatus of the utility model is:
(1) preparation process is simple, application easy to implement;
(2) solved the difficulty of removing dust in silencing apparatus;
(3) extended the service life of silencing apparatus;
(4) ensure that enterprise normally uses;
(5) kept the silencing apparatus noise reduction.
Description of drawings
Fig. 1 is the structural representation of a kind of ventilator silencing apparatus of the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
As shown in Figure 1, preferred forms as a kind of ventilator silencing apparatus of the utility model, it comprises ventilator muffler body 1, the top of described body 1 is provided with outlet 2, the bottom of described body l is provided with import 3, also is provided with resistance housing, deashing door 4 and rubber press strip on described body 1, and described deashing door 4 is installed on the resistance housing, described rubber press strip is arranged between described deashing door and described resistance housing, and described body 1 upper end also is provided with rainhat 5.
As the further optimization of technique scheme, be connected through the hinge between described deashing door 4 and resistance housing, described hinge comprises fastener and fixing bolt.
At impedance complex formula silencing apparatus, resistance is partly installed deashing door.
Deashing door and silencing apparatus resistance partial shell are installed the rubber press strip.
Deashing door is connected hinge, fastener, bolt to be fixed with silencing apparatus resistance housing, detachable during deashing.
The above has done detailed description to the utility model preferred implementation by reference to the accompanying drawings, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
