Description

Technical Field

[0001] The utility model relates to the technical field of fish pond microfiltration, in particular to a microfiltration device for fish farming. Background Art

[0002] There are two types of fish farming: one is fish farming in ornamental ponds, and the other is for breeding. For breeding in ornamental ponds, the water in the pond is generally filtered to filter out the brown algae and other debris formed in the pond to prevent the brown algae in the ornamental fish pond from sticking to the surface and affecting the ornamental value. At the same time, when raising fish, the breeder generally feeds the fish in the pond. Therefore, when too much brown algae and other impurities are produced in the pond, it is easy to have overnutrition, resulting in algae on the surface of the pond, which in turn affects the dissolved oxygen rate of the pond, causing the fish in the pond to die due to lack of oxygen.

[0003] Therefore, microfiltration equipment is generally used in outdoor fish farming to filter algae in the water. The filter screen generally used is cylindrical. At the same time, when filtering, the cylinder rotates under the beating of the water flow. During the filtering process, the cylindrical filter screen needs to be cleaned to prevent the surface filtration speed of the filter screen from being less than the speed of the water entering, so that the height of the water flow is higher than the height of the filter screen, so that the impurities on the surface of the filter screen float on the surface and flow back into the river water. At the same time, there is no designer-related mechanism on the surface of the cleaning mechanism to remove the impurities on the surface, so that the impurities on the surface of the filter screen cannot be discharged in time and flow back into the filtered river water, which causes too many impurities in the river water and too much duckweed, which makes the dissolved oxygen rate of the river water low, affecting the survival rate of the fish.

[0004] In view of the above situation, we propose a microfiltration device for fish farming. Utility Model Content
