I. Centrifugal atomizerWorking principle
The atomizer is a component in the spray drying device that allows the atomized medium to obtain high energy and high speed. It is also a key component that plays an important role in atomization efficiency and stability of the atomization process. . The motor drives the large gear through the coupling, and the large gear meshes with the small gear on the rotating shaft. The increased speed of the first gear shaft drives the second large gear to achieve high-speed rotation of the atomization disk. When the feed liquid enters the feed pipe of the centrifugal atomizer, it flows evenly into the high-speed rotating spray plate through the feed liquid distribution plate. The material liquid is sprayed into tiny atomized droplets, which increases the surface area of the material liquid. Contact with hot air in the drying chamber. Evaporates quickly and can be dried into finished products in a very short time.
Second, Centrifugal Atomizer Structural Features
(1) When the material feed speed fluctuates, the gear transmission speed is constant and the mechanical efficiency is high;
(2) Using a long cantilever structure, the "automatic centering" effect can be achieved when the main shaft is running, reducing the vibration of the main shaft and atomization disk.
(3) Set up a floating bearing and use three fulcrums to support the flexible shaft. This enables the shaft system to quickly cross the critical speed.
(4) Reasonably arrange the fixed support positions. Arrange the fixed support position at the node position to reduce the vibration load of the shaft system.
Technical Overview
Centrifugal atomizer is a widely used process in the liquid processing, molding and drying industry. It is suitable for producing powdery and granular solid products from solutions, emulsions, suspensions and plastic paste liquid raw materials. . Therefore, when the particle size distribution, residual moisture, bulk density and particle shape of the finished product need to meet precise standards. . Spray drying is an ideal process.
Technical features
The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization by the high-speed centrifugal atomizer. In the hot air flow, 95%-98% of the water can evaporate instantly, and the drying time is only a few seconds. Especially suitable for drying heat-sensitive materials.
The product has good uniformity, fluidity and solubility. High purity and good quality. The production process is simplified and operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials). It can be dried into powdery products in one go. There is no need for crushing and screening after drying, which reduces the production process and improves product purity. By changing operating conditions within a certain range,. The particle size, bulk density and moisture content of the product can be adjusted, making control and management very convenient.
