A Dewatering Device to Clean Filtering Materials

This Patent of practical new type is a dewatering device that can clean the filteration materials. It is composed of infiltration pack (3), draining pipe (4), dewatering pipe distribution box (5), sealing wall (6), valve (7) and pipe (8) for high-pressure air. The infiltration pipe (3), and draining pipe (4) are muff coupled on the dewatering pipe distribution box (5) through adaptor (9), the draining pipe goes through the sealing wall (6) and connects with valve (7). The pipe for high-pressure air (8) is connected with the draining pipe outside of the sealing wall via another valve (7). When the filtration materials need to be cleaned, close off the valve (7) for the draining pipe, open the valve (7) for the high-pressure air pipe (8), the high-pressure air blows through the draining pipe into the distribution box (5), and then from where (5) enters the infiltration pipe (4), enforcedly blowing outside from the pipe so as to achieve the purpose of cleaning the filtration materials outside the infiltration pipe.
