Wear-resistant centrifugal atomizing disc with self-balancing function

Abstract

The invention discloses a wear-resistant centrifugal atomizing disc with a self-balancing function. The disc comprises an atomizing disc, an inlet, a nozzle assembly, a balancing disc and a power input assembly, wherein the atomizing disc is a shell with a hollow cavity; the inlet is positioned on the atomizing disc and is used for communicating the inside and the outside of the atomizing disc; the nozzle assembly is positioned on the atomizing disc and is used for spraying out a to-be-atomized material; the balancing disc is positioned on the atomizing disc; and the power input assembly is connected with the atomizing disc and used for inputting power to drive the atomizing disc to rotate. The centrifugal atomizing disc is provided with the balancing disc located in the atomizing disc, the balancing disc can supplement the eccentric weight of the atomizing disc through an elastic effect of an elastic body, the rotating force is evenly transmitted to the whole centrifugal atomizing disc, it is kept that force is evenly applied to a connecting shaft, and the service life of the centrifugal atomizing disc is prolonged; and the nozzle assembly is arranged to replace spraying holes formed in a traditional atomizing disc, so that the abrasion degree of the centrifugal atomizing disc is reduced, and the service life of the centrifugal atomizing disc is prolonged.

Description

technical field [0001] The invention relates to the field of atomization technology, in particular to a wear-resistant centrifugal atomization disc with self-balancing function. Background technique [0002] Atomization technology refers to the operation of dispersing liquid into tiny droplets through nozzles or high-speed airflow. The numerous dispersed liquid droplets that are atomized trap particulate matter in the gas. The methods of liquid atomization include pressure atomization, turntable atomization, gas atomization and sonic atomization. It means that the liquid is turned into small droplets through a special device and sprayed out in the form of mist. Among them, the atomizing disc is the core mechanism in the atomization technology. [0003] Existing centrifugal atomizing discs have some drawbacks: [0004] 1. In the centrifugal atomizing disc, it is necessary to provide high-speed rotational power to the atomizing disc, so that the liquid in the atomizing dis...

Problems solved by technology

[0004] 1. In the centrifugal atomizing disc, it is necessary to provide high-speed rotational power to the atomizing disc, so that the liquid in the atomizing disc can be accelerated in a short time to complete the atomization process. Therefore, a connecting shaft for transmitting power is required. The connecting shaft The power source is transmitted to the atomizing disc, which bears a very large centrifugal force, and has very high requirements on the uniformity of the atomizing disc. Even if the mass of the atomizing disc is a few grams heavier, the centrifugal force formed under high-speed operation will be tens of kilograms , so the unbalanced atomizing disc will cause the input shaft to be easily bent and damaged, and it is impossible for the atomizing disc to be completely weightless;

[0005] 2. During the operation of the centrifugal atomizing disc, its side wall and bottom are prone to wear under the long-term impact of the liquid, that is, figure 1 As shown in B and C of , there are some atomizing discs whose liquid droplet ejection hole is the body material of the atomizing disc, the inner ring of the atomizing disc will be worn, and the sprayed liquid will also damage the outer wall of the atomizing disc. cause wear and tear, i.e. figure 2 As shown in D, it greatly affects the service life of the atomizing disc;
