Description

Technical Field

[0001] The utility model relates to the technical field of water filtering equipment, more specifically to a secondary water circulation recycling device for a fish pond. Background Art

[0002] When fish are raised in existing fish ponds for a long time, more impurities will be generated in the fish ponds. Therefore, the water in the fish ponds needs to be filtered and cleaned every once in a while to prevent the water from being too dirty and causing harm to the fish. Therefore, a circulating water treatment device is usually set in the existing fish ponds. The circulating water treatment device is also called a circulating filter. It is a device used to purify water and oxygenate the water in the fish pond so that the water in the pond can be recycled. Its purpose is to remove dirt such as feces in the water, keep the water clear and circulate it in the fish pond, so that the fish pond has sufficient oxygen, no harmful substances, no pollution, and is suitable for the growth of fish. However, the existing circulating water treatment device often has poor filtering and circulation effects, resulting in poor water quality in the fish pond, which affects the growth of fish. In view of this, the inventor proposes a secondary water circulation recycling device for fish ponds to solve this problem. By filtering and circulating the water in the water pond with high efficiency and high quality, the water quality is improved, making the fish pond suitable for the growth of fish.

[0003] In order to make better use of water resources, effectively filter the fish pond water, remove impurities, floating objects, bacteria and odors, and solve the problem of large waste of fish pond water resources, a Chinese patent application, announcement number: CN210215069U, discloses a circulating filtration device for fish ponds. The utility model includes a filter box, and the filter box is provided with a first filter unit, a second filter unit and a third filter unit from top to bottom. The utility model uses a water pump to extract the fish pond water and send it to the filter box. The first filter unit, the second filter unit and the third filter unit arranged in the filter box will remove large particles of impurities, floating objects, small particles of impurities, bacteria and odors contained in the water. The multi-layer filter unit provided in the utility model improves the water cleaning efficiency. The filtered water can be sent to the fish pond again. The recycling of water saves a lot of water resources and protects the environment.

[0004] This solution still has some shortcomings or needs to be improved in its application. The ecology of the fish pond is complex. Simple treatment of impurities, floating objects and bacteria cannot make the water recyclable. It also includes water temperature, oxygen and pH value. Improper treatment of these factors may cause the death of fish. At the same time, not only the water in the fish pond needs to be recycled, but also the removed sewage needs to be recycled and reused to protect water resources. Therefore, it is necessary to improve the structure of the fish pond water circulation device to make it have better recycling effect, improve the ecology of the fish pond, and promote the practicality of the water circulation device.
