Description

Technical Field

[0001] The present application relates to the technical field of aquaculture, and in particular to a circulation filtration device for aquaculture. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. Aquaculture includes extensive farming, intensive farming and high-density intensive farming. Extensive farming is to release seedlings in medium and small natural waters and grow aquatic products completely relying on natural bait, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming is to use higher-density farming technology in smaller water bodies to grow aquatic products, such as pond fish farming, cage fish farming and pen fish farming. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as flowing water fish farming, factory fish farming, cage eel farming, etc.

[0003] The existing Chinese patent with announcement number CN214801736U discloses a circulating filtration device for aquaculture, comprising a first tank body for aquaculture, a second tank body arranged outside the first tank body and a purification device for circulating and filtering water inside the first tank body, wherein the purification device comprises an inlet pipe arranged inside the first tank body, a water pump connected to the inlet pipe, an outlet pipe connected to the water pump and a filtering component for purifying water discharged from the outlet pipe; the utility model can filter the water in the aquaculture pond for multiple times by arranging the first tank body, the second tank body and the purification device for coordinated use, and can improve the filtering effect of the pond water through different filtering methods, facilitate reflux after filtering, improve the circulating filtration effect of the water, and solve the problem that the existing aquaculture pond cannot circulate and filter the internal water, and the water quality will deteriorate if the water is not changed for a long time, which is easy to cause the quality and output of aquatic products to decrease.

[0004] However, the above-mentioned filtering device has the following disadvantages: the device circulates and filters the water in the breeding pond by setting up a purification device and a filtering component, but the device cannot clean the filter screen used for filtration. If the filter screen is not cleaned for a long time, it is easy for a lot of impurities to accumulate in the filter mesh, reducing the filtering effect of the filter screen, and after the mesh is blocked, it cannot be processed, which further affects the filtering effect and reduces the service life of the filter screen.

[0005] Therefore, we propose a circulating filtration device for aquaculture to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
