[0041] Specifically, a stepped groove 112 is provided in the mounting portion 101. The mounting portion 101 is mounted on the top of the crystallizer through the stepped groove 112. The stepped groove 112 enables the mounting portion 101 to be mounted on the top of crystallizers of different sizes, thereby increasing the applicability of the cleaning device.

[0042] Specifically, there are four second driving devices 105, each of which is connected to the mounting plate 106; the four second driving devices 105 are arranged at equal intervals along the circumferential direction of the connecting portion 104.
