the filter element 14 is formed by laminating a plurality of filter layers with different elasticity, a plurality of hollow pipes which are uniformly distributed in the gravity direction and the circumferential direction are arranged on the outer circumferential surface of the filter element 14, one end of each hollow pipe is vertically and fixedly inserted in the filter element 14, the other end of each hollow pipe is a U-shaped transitional sealing opening, a fine hole is formed in the middle of each sealing opening, namely, the fine hole is formed in the position flush with the axis of each hollow pipe, and a plurality of bulges which are spaced side by side are arranged on the inner wall of the pipe body of each hollow pipe.
Furthermore, the hollow tube is made of plastic.
In the first embodiment, make sewage fully contact through the filter core 14 that turns up, adopt the physics filtration method, make the solid particle who carries in the sewage detain in filter core 14, reach the purpose of purifying sewage, the water after the purification discharges away through water purification discharge pipe 9, but the filter core itself can reach the absorption saturation very fast, its time of endurance is shorter, utilize centrifugal method to carry out temporary separation storage to the hollow tube with particulate matter or silt in the filter core 14 in this embodiment, thereby promote filter core filtration performance by a wide margin, and subsequent washing convenience, concrete working process and principle are as follows:

in addition, the motor which drives the filter element 14 to rotate works in two working modes of acceleration and smooth rotation in turn, and the duration of the acceleration rotation period is shorter than that of the smooth rotation period, for example, in the rotation process of the motor, after 5 minutes of smooth rotation, a variable acceleration period of 30 seconds is carried out, then 5 minutes of smooth rotation is carried out, and then 30 seconds of variable acceleration period is carried out, so that the cycle is repeated. The operation mode of the motor is such that after the filter element 14 has been rotated for a certain period of time to absorb the particles, a centrifugal throwing process is performed, so that the sludge in the filter element 14 is periodically stored in the hollow tube. Although a small amount of sludge can enter the hollow pipe by the centrifugal force generated in the stable rotation process of the motor, the sludge thrown away by the centrifugal force generated in the acceleration period is far less than the sludge thrown away by the centrifugal force generated in the variation period and has strong capability of crossing the raised obstacles in the hollow pipe body, because the centrifugal force generated in the variation period can promote the sludge to creep outwards while intensifying the extrusion deformation among the filter layers in the filter element 14, and the sludge can more easily pass through the raised obstacles in the pipe wall of the hollow pipe.
