Description
Technical field:
The utility model relates to technical field of sewage, relates in particular to a kind of sedimentation basin effluent weir sound-adsorbing sound-insulating hung noise reduction cover plate.
Background technology:
In the conventional sewage disposal plant process flow, in when advancing to go out in week the normal water outlet of formula sedimentation basin (such as second pond), water after the precipitation process flows into braiding channel through the triangle overflow weir at effluent weir top, braiding channel both sides, and subsequently penetration depth treatment process section or direct discharging dispatched from the factory.In this overflow exiting water process, the drop of water level can produce drop sound, and the drop underwater sound that more slumps is then larger.This drop sound is a kind of low-frequency noise.Low-frequency noise has the characteristics such as energy is large, penetrability strong, do not have directionality, propagation distance is far away.The drop low-frequency noise that continues is polluted, the day-to-day operation attendant of sewage treatment plant and the resident of sewage treatment plant's periphery are caused larger harm, not only damage people's the sense of hearing, make the people feel easily tired, produce negative feeling, even all can produce in various degree harmful effect to people's nervous system, cardiovascular system, internal system, digestive system and vision, intelligence etc.Therefore, must take measures the low-frequency noise pollution of sedimentation basin effluent weir is administered.
In order sewage treatment process not to be impacted, conventional sedimentation basin effluent weir drop noise abatement measure is to add a cover certain thickness cover plate at the braiding channel top, such as fibreglass reinforced plastic cover etc., to stop the propagation of the noise that drop causes.In order to increase soundproof effect, see Fig. 1, usually the length of this cover plate 2 will extend to respectively scum board 1 place and sedimentation basin pool wall 7 places of sedimentation basin, scum board 1 is connected with braiding channel wall 6 by scum board bracing frame 5, cover plate 2 is connected by the triangle overflow weir 4 of 6 liang of side roof parts of noise reduction cover plate bracing frame 3 and braiding channel wall, however, because processing and installation accuracy are limit, between cover plate 2 and the scum board 1, between cover plate 2 and the sedimentation basin pool wall 7, more or less having assemblage gap exists, see through these gaps, the drop noise leakage is still arranged out.
The utility model content:
The purpose of this utility model provides a kind of sedimentation basin effluent weir sound-adsorbing sound-insulating hung noise reduction cover plate, it is the route of transmission of blocking-up braiding channel effluent weir drop noise effectively, reduce noise to the impact of surrounding environment, can also save simultaneously cost of investment and the duration of newly-built sedimentation basin, and guarantee the effluent quality of sedimentation basin.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises flap 9, sound-adsorbing sound-insulating hung material layer 10, cover plate maintenance handle 11, flap 9 is rectangle, the two ends of flap 9 are vertically installed with two flap shirt rim 9-1, one side of flap 9 length directions is provided with cover plate sound insulation flanging 12, flap 9 is connected by the triangle overflow weir 4 of 6 liang of side roof parts of noise reduction cover board support 3 and braiding channel wall, sound-adsorbing sound-insulating hung material layer 10 is arranged on the lower inner part of flap 9, and the upside of flap 9 is provided with cover plate maintenance handle 11.
Described flap 9 is stainless steel flap or anti-corrosion material flap.
In the water with the direct immersion precipitation of 9-1 pond, flap shirt rim when the utility model is installed, do not had between cover plate and the scum board, the slit between cover plate and the second pond pool wall, just do not had the leakage of drop noise, sound-adsorbing sound-insulating hung material layer 10 can significantly reduce the ability that the drop noise penetrates cover plate.During flap 9 contiguous concatenation, the noise that cover plate sound insulation flanging 12 both can effectively have been blocked in the effluent weir leaks out from the slit of 9 of two blocks of adjacent flaps, simultaneously, can also block sunlight direct projection from the slit of 9 of two blocks of adjacent flaps enter effluent weir, even so that in summer, also be difficult in the effluent weir grow the microorganisms such as algae and moss, avoided the secondary of effluent quality to worsen.Flap 9 upsides are provided with cover plate maintenance handle 11 convenient for maintaining, when being applied to newly-built sedimentation basin, the shirt rim 9-1 in flap 9 left sides can also replace the scum board of sedimentation basin, and therefore the construction cost of sedimentation basin can be saved to a certain extent, and therefore the construction period also can suitably shorten.
The utility model is effectively blocked the route of transmission of braiding channel effluent weir drop noise, reduces noise to the impact of surrounding environment, can also save cost of investment and the duration of newly-built sedimentation basin simultaneously, and guarantees the effluent quality of sedimentation basin.
