Abstract
The invention discloses an anti-drifting rotating table centrifugal spray nozzle which comprises a flow-diversion cover shell with an upper opening and a lower opening. The flow-diversion cover shell is internally and fixedly provided with a double-shaft motor. An upper shaft of the double-shaft motor is connected with a fan, and a lower shaft is connected with a centrifugal rotating table. The air flow generated by the fan is guided by the inner wall of the flow-diversion cover shell and evenly distributed and downwards acts on a lower rotating table opening of the centrifugal rotating table. A liquid separation cavity is formed between the centrifugal rotating table and the double-shaft motor. The liquid separation cavity is connected with an external liquid source. The side face of the liquid separation cavity is provided with flow-diversion openings. The centrifugal rotating table is of an inverted-bowl-shaped structure, and the flow-diversion openings right face a flow-diversion circular bead on the upper portion of the inner side of the centrifugal rotating table. The anti-drifting rotating table centrifugal spray nozzle has the advantages that the wind power is utilized to make centrifugal liquid droplets have a vertically downwards initial speed, the liquid droplet attachment speed can be increased, and the free floating loss of the liquid droplets in the air is lowered.
