Embodiment 1

[0021] Embodiment one: if Figure 1 to Figure 3 As shown, an exhaust sound-absorbing purification cap includes a cap body 1 , support feet 2 and a diversion cone 3 .

[0022] The diversion cone 3 is conical, and the diversion cone 3 is set upside down, that is, the pointed head is downward, and the diversion cone 3 is fixedly connected with the bottom of the cap body 1; the diversion cone 3 is used to disperse the airflow, even if the airflow diffuses around.

[0023] Both the cap body 1 and the diversion cone 3 are thin-walled components, and the inner cavity of the cap body 1 and the diversion cone 3 are connected together to form a sound-absorbing cavity. There are a plurality of air holes 4 on the side wall of the sound-absorbing chamber, and fillers 5 fill up the sound-absorbing chamber. In order to ensure the effect of air intake and exhaust, and to avoid the leakage of the filler 5, the air holes 4 are numerous and dense, the air holes 4 are arranged in an orderly mann...

Embodiment 2

[0029] Embodiment two: if Figure 4 As shown, the structure and principle of this embodiment are basically the same as those of Embodiment 1, and the basic similarities will not be described redundantly, only the differences are described. The differences are: the cap body 1 is columnar, and the diversion cone 3 is positive Set up vertically, that is, the pointed head faces upwards, the diversion cone 3 is located in the cap body 1, and the diversion cone 3 is fixedly connected with the bottom of the cap body 1; the diversion cone 3 makes the airflow gradually flow into the cap body 1. The bottom of the cap body 1 is fixedly connected with an inclined deflector 7 , and the deflector 7 makes the air flow toward the center of the cap body 1 .

Embodiment 3

[0030] Example three: as Figure 5 As shown, the structure and principle of this embodiment are basically the same as that of Embodiment 1, and the basic similarities are no longer described in detail, only the differences are described, and the difference is that the exhaust noise reduction purification cap does not include the diversion cone 3 , the bottom wall of the sound-absorbing chamber is flat, and the bottom wall of the sound-absorbing chamber is located above the bottom edge of the cap body 1 .

Abstract

The invention provides an exhaust noise reduction purification cap, and belongs to the technical field of ventilation. The exhaust noise reduction purification cap solves the problems that when an existing dust remover is used in a narrow workshop, airflow is prone to generating noise, and a dust pollution area is formed in a wall surface or a ceiling. The exhaust noise reduction purification capcomprises a cap body and supporting legs, a noise reduction cavity is formed in the cap body, a plurality of air holes are formed in the side wall of the noise reduction cavity of the cap body, and the noise reduction cavity is filled with filler; and the upper ends of the supporting legs are fixedly connected with the cap body, the lower ends of the supporting legs are provided with an installation connecting structure, and air dispersing gaps are formed between the installation connecting structure and the cap body. The exhaust sound reduction purification cap can ensure smooth exhaust of the airflow and ensure the efficiency of the dust remover. When the dust remover is used in the narrow workshop, the exhaust noise reduction purification cap prevents the airflow from directly impactingthe wall surface or the ceiling, and the dust pollution area is prevented from being formed on the wall surface or the ceiling. According to the exhaust noise reduction purification cap, by graduallyreducing high-speed large airflow, noise is prevented from being formed, and meanwhile dust in the airflow can be further separated.

Description

technical field [0001] The invention belongs to the technical field of ventilation, and relates to a noise reduction device, in particular to an exhaust noise reduction purification cap. Background technique [0002] A dust collector is a device that separates dust from flue gas. The dust collector must include a fan, and the fan will generate a lot of noise when it is running. Therefore, people think of connecting a muffler in series on the exhaust pipe, such as a smoke and dust purifier (application number 201120355404.4). [0003] When the dust collector is used in a spacious factory building, the muffler can reduce the noise, but when it is used in a narrow factory building, there are usually problems such as the air flow is not smooth, and the distance between the exhaust port and the wall or ceiling is not far enough, which leads to the drop. The noise effect is not obvious, and because the dust removal efficiency of the dust collector is not 100%, the area on the wal...
