雨水蓄集池内的雨水在水压的作用下，会从滤布处进入过滤腔内，过滤腔内的水自动流入缓冲洁净池内，主水管的两端的电控阀打开，吸污管、排污管上的电控阀关闭，缓冲洁净池内过滤后干净的水被水泵抽送到水塔中存储起来，随着雨水的过滤，滤布表面聚集大量杂质，滤布过滤效果显著降低，此时主水管的两端的电控阀关闭，吸污管、排污管上的电控阀打开，水泵开启，电机驱动螺杆转动，清洁管两侧的长槽孔沿着滤布表面移动，从而使得过滤腔内的水穿过滤布连同滤布上的杂质一起被吸入清洁管内，最后被排出，从而恢复滤布的过滤性能，然后主水管的两端的电控阀打开，吸污管、排污管上的电控阀关闭，继续过滤雨水。Under the action of water pressure, the rainwater in the rainwater storage tank will enter the filter chamber from the filter cloth, and the water in the filter chamber will automatically flow into the buffer clean pool. The electric control valves at both ends of the main water pipe are opened, and the suction pipe and sewage pipe The electric control valve on the filter is closed, and the clean water filtered in the buffer cleaning pool is pumped to the water tower for storage. With the filtration of rainwater, a large amount of impurities accumulate on the surface of the filter cloth, and the filtering effect of the filter cloth is significantly reduced. At this time, the two main water pipes The electric control valve at the end of the cleaning pipe is closed, the electric control valve on the sewage suction pipe and sewage pipe is opened, the water pump is turned on, the motor drives the screw to rotate, and the long slots on both sides of the cleaning pipe move along the surface of the filter cloth, so that the water in the filter chamber can pass through. The filter cloth and the impurities on the filter cloth are sucked into the cleaning pipe and finally discharged to restore the filter performance of the filter cloth. Then the electric control valves at both ends of the main water pipe are opened, and the electric control valves on the sewage suction pipe and sewage pipe are closed. Continue to filter rainwater.
如图6所示，长槽孔140与环形密封挡圈141之间的部位设有一圈毛刷安装槽142，毛刷安装槽内安装有毛刷143，毛刷上设有刷毛，长槽孔两侧的刷毛对称分布，长槽孔两侧刷毛外端的夹角为45°-90°，本实施例中刷毛的夹角为60°，刷毛为钢丝刷毛，刷毛的头部设有小钢珠。钢丝刷毛具有一定的刚性和良好的弹性，清洗管移动时，刷毛前端的小钢球在滤布上移动，滤布在钢丝刷毛的压力作用下，与小钢珠的接触面上会发生微小的变形，从而导致滤布上的滤孔被张大，便于滤孔内的杂质排出；由于滤布的内侧为网格板，因此清洗管移动时，小钢珠在滤布表面跳动，导致滤布表面产生振动，从而进一步把滤布上的空隙中的杂质振出来清理掉。As shown in Figure 6, the position between the long slotted hole 140 and the annular sealing retaining ring 141 is provided with a circle of hairbrush installation groove 142, and a hairbrush 143 is installed in the hairbrush installation groove, and the hairbrush is provided with bristles, and the long slotted hole The bristles on both sides are symmetrically distributed, and the angle between the outer ends of the bristles on both sides of the long slot is 45°-90°. In this embodiment, the angle of the bristles is 60°. The steel wire bristles have certain rigidity and good elasticity. When the cleaning tube moves, the small steel balls at the front of the bristles move on the filter cloth. Under the pressure of the steel wire bristles, the filter cloth will slightly deform on the contact surface with the small steel balls. , so that the filter holes on the filter cloth are enlarged to facilitate the discharge of impurities in the filter holes; since the inner side of the filter cloth is a grid plate, when the cleaning pipe moves, the small steel balls dance on the surface of the filter cloth, causing the surface of the filter cloth to vibrate , so as to further shake out the impurities in the gaps on the filter cloth and clean them up.
