Description

Centrifugal sprayer

Technical Field

The utility model relates to the technical field of spraying or atomizing devices with rotating devices, in particular to a centrifugal sprayer.

Background

Atomization refers to the operation of dispersing a liquid into tiny droplets through a nozzle or with a high velocity gas stream, the numerous dispersed droplets being atomized being capable of capturing particulate matter in the gas. The liquid atomization method includes pressure atomization, turntable atomization, gas atomization, sonic atomization and the like.

Centrifugal rotary disk type atomizing disks are generally classified into three types of smooth disks, vane disks and nozzle disks in terms of structural form. Because the liquid is prone to slipping on the smooth disk rotating at high speeds, the ability of the smooth disk to atomize is generally inadequate, so that the smooth disk is less useful except where special demands are placed on the particle size of the product. The blade disc is an atomization disc similar to a blade shape formed by arranging a grating on a smooth disc in order to prevent liquid from slipping on the disc, and a cover plate can be covered on the grating to prevent liquid from sputtering. When certain corrosive materials are encountered, the grating of the blade disc is easily corroded, so that the atomization capability of the blade disc is greatly reduced. To solve this problem, the rectangular outlet of the vane disk is changed to a circular shape while lining the nozzle orifice with a corrosion resistant material, and this type of atomizing disk is called a nozzle disk.

However, in practical applications, the turntable and the blades generate a flow of ambient air during the high-speed rotation, so that the mist droplets and the materials are unevenly mixed.
