Magnetically-driven rotary atomizer

Abstract

The invention relates to a magnetically-driven rotary atomizer. An atomizer shell is connected with an atomizer inner container in a welded mode. An atomizer cover plate is connected with an upper bearing. A feeding device is arranged on the left side of the atomizer shell and the left side of the atomizer inner container, and the feeding device is provided with a feeding opening. A feed liquid distribution disc is arranged at the portion, at the bottom of the atomizer shell, of the feeding device. A feed liquid outlet is formed in the rear side of the feed liquid distribution disc. A main shaft containing space is arranged below the atomizer cover plate, a main shaft is arranged in the main shaft containing space and is a tapered main shaft, and a shaft end cover is fixed to the top of the main shaft through a locking bolt. A plurality of upper bearings are arranged below a connecting end. The upper bearings are connected with the main shaft and the shaft end cover through locking rings. A plurality of magnetic force receiving devices are symmetrically arranged on the periphery of the main shaft, a plurality of magnetic force generating devices are symmetrically arranged outside the magnetic force receiving devices, and the outer portions and the bottoms of the magnetic force generating devices are fixedly connected with a cooling jacket. The cooling jacket is detachably connected with the atomizer inner container.

Description

technical field [0001] The invention relates to the technical field of evaporation and drying, in particular to a magnetically driven rotary atomizer. Background technique [0002] Evaporation and drying of liquids by means of rotary atomization evaporation is a common drying and granulation method. The main method of rotary atomization is that when the liquid is sent to the high-speed rotating atomizing disc, due to the action of centrifugal force, the liquid is stretched into a thin film or drawn into filaments (depending on the rotational speed and the amount of slurry), and breaks at the edge of the atomizing disc Disperses into droplets. The size of the droplets depends on the rotation speed and the amount of liquid handled. The atomizer can ensure that the particle size distribution of the atomized droplets does not change significantly when the liquid flow rate does not change greatly. The atomized liquid is fully and uniformly mixed with the high-temperature gas, ...

Problems solved by technology

Its disadvantages are: in the drying field, the working temperature of the atomizer is generally high, the ambient temperature often reaches above 300°C, and the working temperature near the atomizer is also above 150°C. The ordinary motor and shafting structure cannot operate at this temperature. Long-term operation under low conditions will shorten the life of the atomizer and increase the failure rate

At present, the atomizer is generally composed of a motor, a speed increase box, a cooling and lubrication system, and an atomizing disc; such an atomizer is generally large in size and heavy in weight, which is not conducive to installation and daily cleaning and maintenance.

The structure of the traditional gearbox and shaft system requires high motor power and relatively low energy conversion
