Embodiment Construction
[0011] The specific embodiment of patent of the present invention is illustrated below in conjunction with accompanying drawing:
[0012] The structural principle of the dynamic moment strengthening device of the fixed mechanism of the dirt rotating cleaning part in the pipe of the present invention is shown in figure 1 . The bearing bowl 3 and the reverse spiral flow channel 5 are of an integral structure, or may be of a split structure. The rotating shaft 7 is riveted or welded to the bearing cap 1 and fixed. The helical direction of the reverse helical channel 5 is opposite to the helical (or helical) direction of the rotating cleaning element 11 . The plastic power wheel 9 is integrally formed with the rotating shaft 7 during injection molding. The rotating shaft 7 is connected with a rotating cleaning element 11 . The diameters of the spiral guide fins 6 and the power wheel fins 8 are smaller than the inner diameter of the heat transfer tube 10 . During production, t...
