AI Technical Summary
In existing coal washing equipment, the centrifuge screen basket is easily clogged when processing fine particles, which reduces the outflow channels for water and fine particles, decreases the filtration area, and affects the dewatering efficiency. Existing cleaning methods are ineffective and waste water resources significantly.
The cleaning method combines high-pressure water and tapping. High-pressure water jets and rotating cleaning pipes are used in conjunction with tapping rods to clean the sieve basket. High-pressure water washes away the attached substances, tapping removes stubborn impurities, and the cleaning water is recycled through the filtration system. High-pressure air is then used to blow away residual moisture from the surface.
This method enables rapid and thorough cleaning of the screen basket, reduces water waste, improves dewatering efficiency, lowers the moisture content of the clean coal, and ensures the efficient operation of the screen basket.
