The outer steel wire brush 2.15 is used for removing impurities on the outer filter cylinder 2.4 and ensuring that the filter holes 2.21 on the outer filter cylinder 2.4 are unblocked so as to improve the filtering efficiency.
As shown in fig. 3, a group of inner steel wire brushes 2.6 is arranged in the inner filter cylinder 2.11, the inner steel wire brushes 2.6 are connected with a group of discs 2.5 on the rotating shaft 2.1, and the inner steel wire brushes 2.6 are used for removing impurities on the inner filter cylinder 2.11 and ensuring that the filter holes 2.21 on the inner filter cylinder 2.11 are unblocked; a bottom steel wire brush 2.9 is arranged in a brush groove 2.19 on the top surface of the lower pull rod 2.8, and the bottom steel wire brush 2.9 is used for removing impurities on the disc punching plate 2.14 and ensuring that a filter hole 2.21 on the disc punching plate 2.14 is unblocked; thereby improving the filtering efficiency.
The method of the invention adopts the vortex filter with the functions of coarse filtration and fine filtration to carry out two-pass filtration on the building sewage, and reduces the turbidity of the water to reach the discharge standard regulated by the state. The invention drives the vortex filter to rotate through the motor, so that the sewage forms vortex-shaped flow in the primary sedimentation tank and the vortex filter, firstly, impurities with larger particles are separated from the slurry under the action of centrifugal force, and the impurities with finer particles are secondarily filtered through fine filtration, thereby not only improving the filtration quality, but also effectively improving the filtration efficiency. The device has the characteristics of small volume, convenient installation and repeated turnover use. Meets the construction requirements of environmental protection.
