Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations.

[0037] like Figure 1-Figure 3 Shown are the structural schematic diagram and cross-sectional view of the noise reduction nozzle. Its structure includes a base 11, a nozzle head 12, a nozzle core 13, a bamboo tube 14 and an infusion hose 15; and the nozzle head 12 is provided with a coaxial cavity arranged through the axial direction, the nozzle core 13 is installed in the inner cavity of the base 11 and the nozzle head 12, and the rear end of the nozzle core 13 is connected with the fluid source through the infusion hose 15 , the infusion hose 15 is arranged through the bamboo tube 14, and the front end of the nozzle core 13 faces the front end of the nozzle head 12; The squares of 12 and nozzle core 13 are arranged offset by 45 degrees.

[0038] An axial injection channel is provided inside the nozzle core 13 , and the injection channe...

Abstract

The invention discloses a square inner cavity nozzle with a noise reduction function. The nozzle structurally comprises a base, a nozzle head, a nozzle core, a bamboo joint pipe and a liquid conveying hose. The nozzle head is coaxially installed at the front end of the base, the bamboo joint pipe is installed at the rear end of the base, the nozzle core is installed in inner cavities of the base and the nozzle head, and the rear end of the nozzle core is connected with a fluid source through the infusion hose. The nozzle head inner cavity is a square-column-shaped nozzle inner cavity, and the local section of the nozzle core is square. Extra equipment does not need to be added, evolution of a shear layer in the nozzle is accelerated by changing the shape of the nozzle core and the section shape of the inner cavity of the nozzle, the complete structure of a vortex is destroyed, the purpose of reducing noise is achieved, the manufacturing process is slightly changed, and the nozzle has the advantages of being simple and economical.

Description

technical field [0001] The patent of the invention belongs to a noise reduction nozzle structure in the technical field of nozzle noise reduction, and specifically relates to a nozzle that uses gas as a carrier to spray droplets. Background technique [0002] The commonly used spray production method is pneumatic atomization. The air flow and liquid are collected in two coaxial pipes, the liquid is transported by the central pipe, and the gas is transported by the outer pipe. The liquids contact each other to generate vibration and friction, and after the liquid is broken into fine droplets, the droplets are atomized and ejected at the nozzle. This method is often used in industrial production to achieve directional delivery of cooling liquid or lubricating liquid. [0003] The main function of the nozzle is to realize the atomization of the liquid, so the existing nozzles often only consider technical indicators such as atomization effect and spray distance in the design p...
