Abstract

The invention discloses an automatic backwash filter for a ballast water management system. The automatic backwash filter consists of a cleaning motor, a transmission component, a filter component, a lower cylinder component, an upper cylinder component and a differential pressure instrument, wherein the filter component consists of four filter cartridges; filter tips are uniformly distributed on a sewage discharge shaft; the upper end of the sewage discharge shaft is closed, and the lower end of the sewage discharge shaft is provided with an opening; the transmission component consists of a driving wheel train, a limiting mechanism, a fixed plate and four driven wheel trains; threads are formed in a bearing sleeve through hole and are in threaded connection with a screw shaft; a hollow shaft is provided with a key groove and is connected with the screw shaft through a key; threads are formed on the circumferential surface of the screw shaft, and a key groove with a through end is also formed in the circumferential surface of the screw shaft; a water inlet, a drain outlet, a sewage collecting chamber and four sewage discharge bend pipes are arranged on the lower cylinder component. The automatic backwash filter disclosed by the invention has the characteristics of large filtering area, strong assimilative capacity, small pressure loss, small floor area, small amount of backwash water, good installation and maintenance performance and the like, and can greatly meet actual requirements for ship installation.

Description

technical field [0001] The invention relates to the field of automatic backwashing filters, in particular to an automatic backwashing filter for a ballast water management system. Background technique [0002] When ocean-going ships inject and discharge ballast water, it is easy to cause the spread of harmful aquatic organisms and pathogens across sea areas. The uncontrolled discharge of ballast water has caused serious harm to marine ecology and public health. According to statistics, as many as 3,000-4,000 species of organisms are carried through ballast water every day in the world. The alien organisms that spread with the discharge of ballast water pose a serious threat to the marine environment of the port state. [0003] In order to deal with the biological invasion brought by the ship's ballast water, the International Maritime Organization (IMO) formulated the "Convention on the Control and Management of Ship's Ballast Water and Sediments". According to the prov...
