Abstract

The present invention belongs to the technical field of filters, in particular to a seawater filter in front of a centrifugal backwash pump. Aiming at the problem that the existing filter is inconvenient to use and cannot handle the filter residue well, it is easy to cause re-blocking and affect the use of the filter. The following scheme is proposed now, which includes a box body, a water inlet on one side of the box body, a first water outlet opening on one side of the box body, a backwash pump is fixedly installed in the box body, and an inlet is fixedly installed on one side of the box body. For the water tank, two filter residue boxes are symmetrically and fixedly installed on the water inlet tank, and two second water outlets are symmetrically opened on the water inlet tank, and two box covers are installed symmetrically on one side of the water inlet tank, and the two box covers are Matching with the water inlet box, two baffle plates are installed symmetrically slidingly on the water inlet box, and the two baffle plates are respectively adapted to the two second water outlets. The invention is convenient to use, can recycle the filter residue, prevents the filter from being blocked again, and affects the use of the filter.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a seawater filter before a centrifugal backwash pump. Background technique [0002] At present, the seawater filter before the pump installed on the ship generally adopts the standard CB / T497 or CBM1061. The filter is installed at the suction end of the seawater pump to intercept the larger particles of impurities in the seawater. However, at the input end of the seawater pump, the space where the filter is installed is very narrow, the filter is surrounded by pipelines or valves, the maintenance space is small, some filters are often submerged by stagnant water, and the front of the pump itself does not have a backwash function. The cleaning of the filter can only be done manually, which brings great inconvenience to the repair and maintenance of the filter, so a fully automatic backwash filter is needed. [0003] However, after the filter residue on the filter screen is washed...
