Dry ice cleaning nozzle with multi-angle flow direction

Abstract

The invention relates to a dry ice cleaning nozzle with a multi-angle flow direction, and belongs to the technical field of dry ice cleaning. The dry ice cleaning nozzle comprises a spray head, a spray pipe, a locking device and a fixed seat, wherein the spray pipe is rotationally connected with the spray head, the locking device is arranged between the spray head and the spray pipe, the spray head and the spray pipe are rotationally adjustable through the locking device, a plurality of spray holes are annularly formed in the spray head, a spray flow pipeline is arranged in the spray pipe, each spray hole corresponds to one spray flow pipeline, the included angles between the spraying directions of the spray holes and the rotating axis of the spray head are different from each other, the fixing base is arranged at the tail end of the spray pipe, and the spray pipe communicates with a dry ice supply device. According to the dry ice cleaning nozzle with the multi-angle flow direction, the angles of the spray head are different, the positions of the spray head are adjustable, multiple spraying flow directions are achieved, cleaning is more uniform, and the cleaning effect is higher.

Description

technical field [0001] The invention relates to a dry ice cleaning nozzle with multi-angle flow directions, belonging to the technical field of dry ice cleaning. Background technique [0002] Dry ice blasting uses compressed air and dry ice particles as power and cleaning materials, and is sprayed onto the surface of the object to be cleaned by a special jet cleaning machine to clean the surface of the object. Since it will not affect the surface of the object to be cleaned, especially Any damage to the metal surface will not affect the smoothness of the metal surface. Therefore, the application range of dry ice blasting is becoming more and more extensive. However, the existing nozzles for dry ice blasting are fixed structures, and the spraying direction is fixed and cannot be adjusted. The dead angle that is difficult to be cleaned by spraying, the spraying direction is fixed, resulting in uneven spraying, uneven cleaning, and poor cleaning effect. Contents of the invent...
