In this embodiment, the deviation rectifying mechanism further includes a driving structure capable of driving the adjustment wheel connecting plate 21 to swing, a handle 25 in the driving structure is inserted on the limiting rod 23, positioning blocks 24 are disposed at two ends of the limiting rod 23 and can be used for limiting the swing angle of the handle 25, the handle 25 is pulled, the movement is transmitted to the connecting rod 27, the connecting rod 27 transmits the movement to the connecting shaft 26 through the radial knuckle bearing, and further the purpose of driving the adjustment wheel connecting plate 21 on the connecting shaft 26 to swing is achieved, the handle 25, the connecting rod 27 and the connecting shaft 26 are arranged here as labor-saving levers, the connecting rod 27, the connecting shaft 26 and the adjustment wheel connecting plate 21 are also as labor-saving levers, and two paths of labor-saving levers are arranged in this way, so that the action amplitude input at the handle 25 is large, but the output end, namely the swing amplitude of the adjustment wheel connecting plate 21 is, the adjustment structure can be driven only by pulling the handle 25 by one person, and after the adjustment is completed, the positioning block 24 can be used for positioning the position of the handle 25 to prevent the handle 25 from swinging randomly.

Further, also comprises

And the water return disc 28 is positioned below the crystallization wheel 1 and is arranged at a water outlet 29 of the external circulating water structure.

In this embodiment, the water return plate 28 is disposed at the water outlet 29 of the external circulation water structure, so that the cooling water can be reused, and the used cooling water does not pollute the working environment.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
