Abstract
The utility model relates to a rotary spray-expanding spray head, which comprises a nozzle core and a nozzle cover. An inner thread that is matched with the water source pipe is arranged at the tail part of the nozzle core and a tapered cavity and a cylindrical cavity are successively arranged at the front part of the inner thread, while the front part of the inner thread is provided with a radial through hole that is acted as a diversion hole and the forefront of the nozzle core is a columnar body on which a plurality of uniformly-distributed spiral paths are provided. An inner thread that is matched with the outer thread of the nozzle core is arranged at the tail part of the nozzle cover and a cylindrical hollow cavity is arranged at the front part of the inner thread, while the central position of the front end face of the cylindrical hollow cavity is provided with a jet hole in the front of which a trumpet-like spout is provided. A gap is arranged between the front end face of the nozzle core and the front end face of the cylindrical hollow cavity of the nozzle cover. The utility model has the advantages of less demand of hydraulic pressure, large spraying angle, small water consumption, strong defoaming capability, which is not prone to be jammed and especially suitable for eliminating foams in the aeration tank.
Description
Technical field
The utility model relates to the defoaming device that is used for the sewage aerobic pond.
