Description

Technical Field

[0001] This utility model relates to filtration equipment, specifically aquaculture filtration equipment, and belongs to the field of aquaculture technology. Background Technology

[0002] Aquaculture refers to the process of artificially planning breeding sites to cultivate aquatic products, such as the cultivation of various fish, seafood, and algae. Through aquaculture, the quantity of aquatic products can be artificially increased to meet the needs of various consumer groups.

[0003] In aquaculture, filtration equipment is used to treat the aquaculture water. This equipment removes impurities such as feces, ensuring the cleanliness of the water and facilitating its recycling. Existing filtration devices use rotating screens to filter the water. For example, using screens with specific pore sizes can meet the needs of aquatic products with different growth requirements. The screens are fixed to the outside of the support frame using various bolts and other fasteners. When the aquaculture water flows inside the filter cartridge, it filters out impurities, which remain inside the cartridge and are discharged to the outside as it rotates. However, the screens in these products can only filter impurities of a single diameter and cannot filter the water by different sizes. Filters with only a single filtration function experience more severe wear and tear during use, affecting their longevity. Therefore, we offer aquaculture filtration equipment to solve these problems. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This aquaculture filtration equipment utilizes the cooperation between filter screen one, filter screen two, and a fixing frame. Filter screen one and filter screen two are fixed inside the protective shell by support frame one and support frame two, with filter screen one located outside filter screen two. Filter screen two has a coarse filtration function, while filter screen one has a fine filtration function. The aquaculture water entering the support shaft first undergoes coarse filtration through filter screen two, which can screen out impurities with larger diameters in the aquaculture water. Then, filter screen two can screen out impurities of other diameters in the aquaculture water. This reduces the risk of increased wear and tear associated with a single filtration function, extending the service life of filter screens and other filtration components. It achieves the function of separating coarse and fine filtration of aquaculture water during the aquaculture process, which helps reduce wear and tear on the filter screens under a single filtration function.
