Description
Technical Field
The utility model belongs to the technical field of the ventilation, a silencing device, especially a amortization purification cap of airing exhaust is related to.
Background
A dust collector is a device that separates dust from flue gas. The dust collector necessarily includes a fan which generates a large noise when operating, and for this reason, it is conceivable to connect a silencer, such as a smoke purifier, in series with the exhaust duct (application No. 201120355404.4).
When the dust remover is used in a spacious factory building, the silencer can reduce noise, but when the dust remover is used in a narrow factory building, the problem that airflow flows unsmoothly and the distance between an air outlet and a wall surface or a ceiling is not far enough exists usually, and then the noise reduction effect is not obvious, and the dust removal efficiency of the dust remover is not 100%, so that the region opposite to the air outlet in the wall surface or the ceiling is very easy to become dirty.
For this reason, it is conceivable to use a noise reduction cap having a structure for changing the flow direction of the air stream, such as a roof fan cap (application No. 200920271596.3), a noise reduction cap (application No. 201821992227.9). The air volume and the air pressure difference in the dust remover are very important technical requirements, and the air volume of the dust remover is larger, so that the smoothness of air flow can be seriously influenced by the silencing cap, the air volume of the dust remover is further reduced, the air pressure difference is reduced, and the dust collection and dust removal efficiency of the dust remover is influenced; because the dust removal efficiency of the dust remover is not 100%, dust is easy to adhere to the interior of the silencing cap, and the silencing effect and the service life of the dust remover are influenced.
Disclosure of Invention
The utility model provides an exhaust silencing purification cap, which solves the technical problem of ensuring the efficiency of a dust remover and reducing noise; it is desirable to reduce the noise of the airflow when the dust collector is used in a narrow factory.
The to-be-solved technical problem of the utility model can be realized through the following technical scheme: an exhaust silencing and purifying cap comprises a cap body and supporting legs, wherein a silencing cavity is arranged in the cap body, a plurality of air holes are formed in the side wall of the silencing cavity of the cap body, and a filler is filled in the silencing cavity; the upper end of the supporting leg is fixedly connected with the cap body, the lower end of the supporting leg is provided with an installation connecting structure, and a wind-dispersing gap is formed between the installation connecting structure and the cap body.
When in use, the exhaust silencing and purifying cap is arranged on other parts, such as an exhaust pipe or a shell of a dust remover, through the mounting and connecting structure. The supporting legs enable a certain distance to be reserved between the cap body and the end port of the exhaust pipe, after the air flow is exhausted through the exhaust pipe, part of the air flow is diffused to the periphery through the air-diffusing gap, and the other part of the air flow impacts on the cap body. The air flow is diffused to the periphery at the blocking lower part of the cap body, and the space between the cap body and the port of the exhaust pipe ensures that the air flow can be diffused smoothly. Most of the air flows through the air holes and enters the silencing cavity, the air pressure on the side, opposite to the air flow, of the cap body is larger than the air pressure on the other side, obviously, the air flow enters the air holes in one side wall of the silencing cavity, is discharged from the air holes in the other side walls and diffuses to the periphery. The filler makes the amortization intracavity form numerous circuitous tortuous passageways, and then makes the big air current that flows rapidly divide into a plurality of gentle flowing little air currents gradually, and the amortization of airing exhaust purifies the cap from this has the amortization function, and the air current dust is the adhesion gradually on the filler in the flow process simultaneously, has the dust removal function, can improve the dust collection efficiency of dust remover.

In the above-mentioned exhaust silencing and purifying cap, the cap body may be in any one of a frustum shape and a columnar shape. The frustum-shaped cap body enables the air flow central area to have a larger stroke relative to the outer area through the exhaust silencing and purifying cap, and the stroke is matched with the speed of the air flow central area relative to the outer area, so that the silencing effect and the dedusting effect are improved, and the using amount of the filler is reduced.
In the above-mentioned air exhaust silencing and purifying cap, when the cap body is in the shape of a frustum, the bottom area of the tapered side wall of the cap body is a flow blocking part; or when the cap body is columnar, the bottom of the cap body is fixedly connected with a guide plate which is obliquely arranged. The flow blocking part and the flow guide plate can improve the flow of air flowing through the cap body, reduce the diffusion amount, further reduce noise and eliminate dust pollution areas in the wall or the ceiling as far as possible.
In the above-mentioned exhaust silencing and purifying cap, the exhaust silencing and purifying cap further comprises a conical diversion cone, and the diversion cone is fixedly connected with the bottom of the cap body; the guide cone is also provided with a plurality of air holes communicated with the silencing cavity. The flow guide cone not only enables the central area of the airflow to be more easily dispersed, but also enables the airflow to gradually enter the silencing cavity, so that the flowing smoothness of the airflow is improved, and the possibility of generating turbulent flow is reduced.
The flow guide cone can be installed in any one of the following manners, namely, in the exhaust silencing and purifying cap, the pointed end of the flow guide cone is arranged downwards, and the inner cavity of the cap body is connected with the inner cavity of the flow guide cone. Secondly, in the above-mentioned silencing and purifying cap for exhausting air, the pointed end of the diversion cone is arranged upward, and the diversion cone is located in the cap body.
