Description

Technical Field

[0001] The utility model relates to the technical field of water filtration, in particular to a water filtration device for fish breeding. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive farming, intensive farming and high-density intensive farming.

[0003] For example, the Chinese utility model patent with patent publication number CN216677232U includes a water purifier body, a water inlet and a water outlet are respectively arranged on both sides of the water purifier body, two sewage outlets are arranged on the front of the water purifier body, and four bases are fixedly connected to the lower surface of the water purifier body. The patent uses a cleaning component to make the four moving seats slide along the inner wall of the water purifier body, thereby driving the two roller brushes to slide up and down. At this time, as the roller brush is squeezed with the filter plate, the roller brush rotates during the movement. The roller brush moves to clean the filter plate. When the cleaning is completed, the residue of the water purifier body is discharged and collected through the sewage outlet. However, when the filter plate is cleaned by the roller brush, since the roller brush is connected to the sliding seat in rotation, the roller brush contacts the filter plate during cleaning. The friction between the two will cause the roller brush to rotate, and the rotation direction is connected to the movement direction, which causes the contact point between the roller brush and the filter plate to be relatively stationary during the movement, thereby reducing the cleaning efficiency. In view of this, we propose a water filtration device for fish farming. Utility Model Content
