Circulating water filtering system

Abstract

The invention relates to a circulating water filtering system. The circulating water filtering system is formed by detachably assembling one or more filtering barrels, each filter barrel comprises a barrel body, a filter screen and a barrel cover, each barrel body comprises a barrel bottom and barrel walls, a horizontal barrel body linking groove and a vertical barrel body linking groove are formed in the barrel walls of one group of opposite side edges of the barrel bottom, and pipeline mounting holes are formed in the barrel walls on the other group of opposite side edges of the barrel bottom; the barrel bodies of the adjacent filter barrels are matched and connected through the pipeline mounting holes and water pipelines to form a circulating water path, wherein a circulating power device is arranged in the barrel body of one filter barrel in a matched manner, and the power supply end of the circulating power device is connected with an external power supply through a power line; the filter screens are mounted at barrel openings of the barrel bodies and are provided with through holes; and the barrel covers are detachably mounted at the barrel openings of the barrel bodies and cover the filter screens. The circulating water filtering system is simple and convenient to mount and dismount, can be freely combined to a greater extent, saves space, enlarges the filtering space toa greater extent, and enhances the capacity of a nitrification system.

Description

technical field [0001] The invention relates to a fish breeding circulating water filtering device, in particular to a circulating water filtering system. Background technique [0002] At present, for ornamental fish and laboratory fish farming, circulating water filtration is generally used to achieve the purpose of water quality cleanliness. For traditional filter devices, because of the different sizes and specifications of fish tanks, there are various types of filter materials and various models, but the shapes are irregular, the models are limited, and the space occupies a large area. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned background technology, the present invention proposes a simple and reasonable structural design, easy installation and disassembly, more free combination and space saving than traditional filter cartridges, larger filtering space, and enhanced nitrification system Capacity circulating water filtra...
