Inclined turnover filter device and filtering method

Abstract

The invention discloses an inclined turnover filter device and a filtering method. The inclined turnover filter device comprises an inclined cylinder and a rectangular filter plate arranged on an axial central surface in the cylinder, wherein the inner cavity of the cylinder above the filter plate forms a water inlet cavity; the inner cavity of the cylinder below the filter plate forms a water outlet cavity; a water inlet is formed in the water inlet cavity side of the upper end surface of the cylinder; a water outlet is formed in the water outlet cavity side of the lower end surface of the cylinder; sundry outlets are formed in the water outlet cavity side of the upper end surface of the cylinder and the water inlet cavity side of the lower end surface of the cylinder; a rotating shaft ishorizontally fixed to the centers of the two sides of the cylinder; the cylinder is rotatably arranged on a machine frame through the rotating shaft. The inclined turnover filter device effectively solves the problems that the filter device in the prior art easily causes dirt accumulation, a filter screen needs to be frequently cleaned, and thus manpower and material resources are wasted; the inclined turnover filter device is simple in structure, can automatically clean the filter screen by backflushing, and has a very high practical value.

Description

technical field [0001] The invention belongs to the technical field of aquaculture filtering devices, and in particular relates to a tilting reversible filtering device and method for filtering large particle impurities at the primary stage of a filtering system. Background technique [0002] At present, marine aquaculture often needs to build a breeding pond, and then introduce seawater, and seawater often contains debris and sediment, so it needs to be filtered before seawater enters the breeding pond, and the current seawater filtration mainly uses filter mesh and natural precipitation and other treatment methods. Because the filter screen is easy to accumulate sundries, it needs to wash the filter screen frequently, which is time-consuming and laborious; natural sedimentation requires a relatively large sedimentation tank and a long sedimentation time. The publication date is June 8, 2016, and the Chinese patent document with the publication number CN205284659U disclose...
