Rotary atomization technology uses high-speed rotating equipment to atomize liquid materials into micron-sized droplets. Its core equipment is a rotary atomizer, which is driven by a high-speed motor to rotate at high speed. The high-speed rotating atomizing turntable generates strong centrifugal force, and materials in the form of suspension or emulsion are sprayed through the specially structured nozzle of the atomizing turntable, thereby being atomized into micron-sized droplets. Rotary atomizer is a key electromechanical product widely used in chemical industry, pharmaceutical, food, environmental protection and other fields. In the field of air pollution control and environmental protection, rotary atomizers include the Niro atomizer, which is commonly used for power plant flue gas desulfurization and waste incineration power plant exhaust gas purification. A common type of rotary atomizer on the market has the characteristics of high speed, stable operation, small vibration, continuous rotation, and long service life. It can be widely used in high-speed spray dryers to spray-dry liquid materials into powdery finished products, and can also be used in other industrial fields for atomization. But its disadvantages are: large power loss and high maintenance costs.
In view of the shortcomings of the existing technology, technicians provide a new type of Niro atomizer, which can effectively reduce power loss and maintenance costs. It adopts the following technical solution: the rotary atomizer includes a direct drive, a main shaft and an atomization disk. The direct drive is connected to the main shaft through a permanent magnetic coupling; the atomization disk includes an atomization disk mounting seat and an atomization disk body. The atomization disk body is a cylindrical cavity. The side walls of the cylindrical cavity are evenly distributed with through holes, and nozzles are installed in the through holes; the upper part of the atomization disk body is fixedly connected to the atomization disk mounting seat, and the end of the main shaft is fixedly connected to the center of the atomization disk mounting seat. It also includes a connecting piece, a feed pipe and a support frame, and the feed pipe is arranged on the support frame.
It should be noted that the permanent magnet coupler of the Niro atomizer includes a conductor mounting frame and a permanent magnet connecting column. The conductor mounting frame is fixedly connected to the output shaft of the motor. The two opposite side walls of the conductor mounting frame are respectively A conductor ring is fixedly connected; a spring is connected between two opposite permanent magnet mounting parts. Each permanent magnet mounting part is fixed with a permanent magnet ring opposite to the corresponding side conductor ring. The two permanent magnet mounting parts are fixedly connected through two upper and lower stud bolts. The upper and lower ends of the permanent magnet mounting piece are respectively provided with through holes through which stud bolts pass. The two ends of the stud bolts respectively pass through the two through holes at the same end of the two permanent magnet mounting pieces. The two ends of the stud bolts are respectively installed with fastening nuts. There are fan blades on the side of the connecting column.
Compared with the existing technology, the Niro atomizer has the following beneficial effects: 1. By optimizing the structure, the direct drive is connected to the main shaft through a permanent magnetic coupling, which overcomes the power loss problem caused by the gear speed increase box and coupling in the traditional rotary atomizer, greatly reducing equipment maintenance costs and improving economic benefits. 2. The atomizer disk can be easily removed and replaced through the connecting piece, which is beneficial to future maintenance and use. 3. In the present utility model, when the atomization disk is stationary, the closable channel on the atomization disk body is opened, and the lower end of the feed pipe is aligned with the closable channel on the atomization disk body, which can quickly add materials to the atomization disk body and improve operating efficiency. 4. By improving the design, on the one hand, a constant air gap is ensured during normal rotation; on the other hand, when the permanent magnet ring and the conductor ring collide due to external force, it can play a good buffering role, making the Niro atomizer more durable
