Problems solved by technology

[0015] The current filter on the market is a ballast water filter application number 201520424042.8 disclosed in Chinese patent literature. This equipment uses different single-layer filter elements. By changing the structural form of the filter element, the filter occupies less space and can Increase the filtration flow, but its backwashing system and fouling problems have not been effectively solved, so after a long time of operation, the filter is easy to clog, and the backwashing effect is not good, and the filtering effect becomes worse

Abstract

The invention aims at providing a horizontal ballast water filtering device with a pleated filter screen. The horizontal ballast water filtering device with the pleated filter screen comprises a barrel, a front cover plate, a back cover plate, a filter core, a hollow sewage discharge shaft and a sewage discharge chamber, wherein the front cover plate is fixed to the front end part of the barrel; the back cover plate is fixed to the back end part of the barrel; filter core clamping ports are formed in the front end and the back end of the inner part of the barrel respectively; the filter core is mounted between the filter core clamping ports in the front end and the back end; a water inlet is formed in the front cover plate; a water outlet is formed in the barrel; one part of the hollow sewage discharge shaft stretches from the back cover plate into the barrel, and the other part of the hollow sewage discharge shaft is positioned outside the back cover plate and is fixed by a rotating shaft mounting port on the back cover plate; the sewage discharge chamber is formed in the end part of the hollow sewage discharge shaft; a sewage discharge pipe is mounted below the sewage discharge chamber; a sewage suction pipe stretches out of the hollow sewage discharge shaft; a sewage suction head is mounted on the end part of the sewage suction pipe. The horizontal ballast water filtering device with the pleated filter screen has a small floor area, can effectively solve the blocking problem caused by filtration, has a good effect of filtering suspended plants and animals in ballast water, can achieve simultaneous operation of filtration and backflushing and shortens the operating cycle.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a ship ballast water treatment device. Background technique [0002] Article 1 of the text of the International Convention on the Control and Management of Ships' Ballast Water and Sediments (hereinafter referred to as the "Ballast Water Convention") states that "ballast water" refers to the control of draft, trim, heel, stability or stress of a ship. And the water loaded on the ship and the suspended matter in it. "Sediment" refers to the material that settles in the ship from the ballast water. When a ship takes on ballast water, it also takes on the substances that are in the ballast water. Contains solid matter in muddy or shallow water, when these matter enters the ballast tanks, will settle on the bottom as "sediment", and may become a breeding ground for a variety of aquatic life to live and live. From the above two definitions, it is not difficult to find that the ballast wa...
