Description

Technical Field

[0001] The invention relates to the field of stirring device processing, and in particular to an assembled adjustable stirring paddle. Background Art

[0002] A stirring paddle is a tool used for stirring. It is an important component in the mixing equipment. The structure and blade shape of the paddle determine the overall stirring form of the liquid in the kettle. Conventional stirring forms include anchor type, paddle type, turbine type, propulsion type, frame type, etc. When the height-diameter ratio of the stirring device is relatively large, a multi-layer stirring paddle can be used. In order to facilitate installation, transportation, adjustment and other functions, some combined stirring paddles have appeared, such as the combined stirring paddle proposed in application number: CN201110088762.8 to improve the leaching rate of metal manganese electrolyte. However, this type of stirring paddle generally uses more bolts for connection. Once it is used for a long time, the probability of its bolts loosening becomes higher. At the same time, most of this type of stirring paddles cannot adjust the angle of each stirring blade, which affects the scope of application of the stirring paddle. Summary of the invention

At this time, the rear end faces of cube A and cube B are against the bottom of the splicing groove, screw hole A, screw hole C and a screw hole D of the blade inserted into cube B are coaxial and have equal inner diameters, and bolts are used to screw in to fix connector A, connector B and blade, screw hole B and a screw hole D of the blade inserted into cube A are coaxial and have equal inner diameters, and bolts are used to screw in to fix connector A and blade.
