[0027] Furthermore, a slot 13 is provided on the top surface of the plug plate 7, and a parallel plug 14 is engaged inside the slot 13. Several grooves 16 are evenly provided on the surface of the plug plate 7.

[0028] During operation, the structure design of having several grooves 16 evenly distributed on the surface of the insert plate 7 facilitates the adsorption of solidified sludge on the surface of the insert plate 7, making it easy to clean the impurities inside the device.
