Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic ballast water treatment, in particular to an electrolytic ballast water treatment device. Background Art

[0002] In order to solve the problem of marine biological invasion caused by ship ballast water discharge operations, the Ballast Water Treatment Convention came into being. This convention requires that certain treatments be performed during ship ballast water discharge operations. The electrolytic ballast water treatment device is divided into three steps: filtration, electrolysis and neutralization. The filtration step plays a very critical role in the electrolytic ballast water treatment device. The filter element in the filter tank of the filter device needs to be removed and cleaned after long-term use to ensure the filtering effect of the filter device on the water quality.

[0003] However, when cleaning the filter element in the filter tank of the existing filter device, it is necessary to open the sealing cover of the filter tank by a lifting device, and take out the filter elements inside the filter tank for cleaning one by one. Since there are a large number of filter elements inside the filter tank, it is cumbersome to complete the process of taking out and cleaning the filter elements one by one, which is time-consuming and labor-intensive, and affects the cleaning efficiency of the filter element. In addition, the sealing cover of the filter tank is mostly connected to the filter tank by a flange with bolts and nuts to achieve the sealing of the filter tank, which makes the disassembly and assembly process of the sealing cover cumbersome and poor in practicality. Utility Model Content
