Self-rotation swing spray head for high-pressure cleaning

Abstract

The invention discloses a self-rotation swing spray head for high-pressure cleaning. The outer part of a shell comprises an inlet end cover, a No.2 end cover, an outer shell, a No.3 end cover, a nozzle shell and a nozzle protection cover sequentially arranged from back to front; the inner part of the shell comprises an impeller, a retarding mechanism and a swing mechanism sequentially arranged from back to front; the retarding mechanism is arranged on the outer shell through an inner end cover; and the swing mechanism is arranged on the No.3 end cover. The retarding mechanism comprises three groups of planetary reducers; the impeller transmits a torque to the first group of planetary reducer, then transmits to the second group of planetary reducer, and finally transmits to the third group of planetary reducer through an input shaft, and outputs the torque to the swing mechanism through an output shaft, so that a nozzle is rotated and swung at the same time. The output shaft, an inertia wheel, a branch pipe and a nozzle branch pipe are of hollow structures; and a high-pressure water flow sequentially passes through and then enters the nozzle through the branch pipe and the nozzle branch pipe so as to be ejected. The self-rotation swing spray head for high-pressure cleaning is simple in structure, convenient to plan a runner and seal, compact in structure, small in size, high in cleaning efficiency, modular in internal structure, and convenient to disassemble, assemble and maintain.

Description

technical field [0001] The invention relates to a high-pressure jet cleaning device, in particular to a high-pressure cleaning self-rotating swing nozzle. Background technique [0002] At present, domestic storage tank cleaning mainly adopts manual cleaning method, but this method has high requirements on the number and quality of operators, and the working environment is very unfriendly to operators, and there are toxic and harmful gases in the storage tank, so automatic high-pressure water jet cleaning has become It has become an inevitable trend, and its core component, the self-rotating nozzle, will also occupy a large market in the future. At present, the more mature nozzle is the omni-directional rotating nozzle, but for chemical containers, the dirt is mainly at the bottom of the container, and for the container wall and top. Surface cleaning requirements are not high, the cleaning efficiency of this type of nozzle is low, and water resources are wasted. Contents of...
