Embodiment Construction

[0016] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0017] see figure 1 . It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the implementation of the present invention. Limiting conditions, so there is no technical substantive meaning, any modification of structure, change of proportional relationship or adjustment of size, without affecting the effect and purpose of the present invention, should still fall within the scope of the present invention. The disclosed technical content must be within the scope covered. At the same time, term...

Abstract

The invention provides a rotary noise reduction device capable of removing static electricity and dust in a pulse mode and meanwhile lowering friction noise of a pulse air flow to the smallest through design on an air passage structure, so that the dust and the static electricity are removed in a buffer mode. Under the condition of a certain pressure, when the air flow blows towards an air passage through an outer shell, the air flow directly acts on a swing nozzle through the section air passage, so that the swing nozzle rotates at a high speed under a high-pressure effect; when the swing nozzle deviates from the air passage, the air flow is small; when the swing nozzle is in parallel with the air passage, the air flow is large, so that the pulse air flow is formed; and when the pulse air flow passes through a noise reduction spray head and brings an external air flow into an air outlet head through a noise reduction hole array at the end of the noise reduction spray head, the friction noise of the internal pulse air flow and the air flow brought into by the external edge noise reduction hole array are countered, so that the purpose that electricity and dust quick removing through pulse noise reduction is achieved.

Description

technical field [0001] The invention relates to a rotary noise reduction device. Background technique [0002] The clean room has high requirements for the concentration of suspended solids in the air. When entering and leaving the clean room, no matter the human body or parts must pass through the cleaning area to remove dust before entering the clean room. Since there are multiple cleaning air guns in the cleaning area, high-decibel noise will be generated during dust cleaning, which will bring discomfort to the operators. Therefore it is particularly important to arrange the silencer nozzle on the air gun. By investigation, there is no silencer nozzle device on the existing air gun in the market in the industry. [0003] Patent announcement number CN202789045U discloses a double-ring muffler, which is characterized in that a circular nozzle plate is arranged at one end of the cavity, and a plurality of steam branch pipes run through the circular nozzle plate transversel...
