The ballast water pretreatment device with the backwashing function comprises a shell, a water inlet pipe, a first water outlet pipe and a second water outlet pipe are arranged on the shell, the second water outlet pipe is located at the position, close to the lower end, of the side face of the shell, and the water inlet pipe and the first water outlet pipe are located on the opposite side faces of the shell; a filtering piece capable of moving up and down is further arranged in the shell, a floating block is arranged on the filtering piece, a sealing film is arranged on the floating block, the upper end of the sealing film is connected with the side wall of the shell, the water inlet pipe extends to the lower portion of the filtering piece, and after the device is used for a long time, a large amount of impurities, sludge and the like can be accumulated in the shell, and at the moment, the filtering piece can move up and down. When the water inlet pipe is closed and the second water outlet pipe is opened, seawater in the shell can flow out through the second water outlet pipe, and when the seawater in the shell is about to completely flow out, water in the backwashing water tank can flow out through the through hole, and the filtering piece can be washed to a certain extent, so that the backwashing effect is achieved.

    本发明公开了一种具有反冲洗功能的压载水前处理装置,包括外壳,在外壳上设置有进水管、第一出水管以及第二出水管,第二出水管位于外壳的侧面靠近下端的位置,进水管与第一出水管位于外壳的相对侧面上,在外壳内还设置有能够上下移动的过滤件,在过滤件上设置有浮块,浮块上设置有密封膜,密封膜的上端与外壳的侧壁相连,所述进水管延伸到过滤件的下方,在本装置长时间使用后,在外壳内可能会积留有大量的杂质、污泥等,此时,关闭进水管,打开第二出水管,外壳内的海水能够通过第二出水管流出,且在外壳内的海水快要流完的时候,反冲洗水箱内的水能够通过通孔流出,还能对过滤件进行一定程度的冲洗,以实现反冲洗的效果。
