The Receiver(National Patent,Website:http://www.chinarebo.com, Patent Number: 2009200694784)The receiver uses jacketed type, which is mainly used to connect the stator and the metal hose. Besides, it also has two functions. One is that it can match stator's rotation because in order to get high-quality drop particles, the dropping angle of the stator needs to adjust according to material's viscosity. The receiver needs to rotate 5~10°, so it is also rotation joint. The second is that the receiver contains a filter, but it is not used for filtering. Instead, it is used to ensure the holes of the stator nozzle, the metering bar and the rotating shell not to be blocked.
