[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a water purification and circulation device for fish fry farming includes an inlet pipe 1. The device is characterized in that: a purification device 2 corresponding to itself is fitted around one end of the inlet pipe 1; the purification device 2 includes a separation chamber 21 sealed to the inlet pipe 1; several uniformly distributed sedimentation pipes 22 corresponding to itself are provided above the separation chamber 21; a filter layer 23 is provided at the end of the sedimentation pipes 22 away from the separation chamber 21; an outer shell 11 corresponding to itself and penetrated by the inlet pipe 1 is fitted around the separation chamber 21; and a water storage tank 13 is connected to the end of the outer shell 11 away from the separation chamber 21 via an arched connecting pipe 12.

[0026] In this implementation scheme, an inlet pipe 1 is used to introduce the water to be treated into the system, while the purification device 2 is directly sleeved and sealed to one end of the inlet pipe 1. Inside the purification device 2, the key component is the separation chamber 21, located at the end of the inlet pipe 1, which is used for the initial separation of solid impurities in the water. Several sedimentation tubes 22 are evenly distributed above the separation chamber 21. These sedimentation tubes 22 guide the water flow, causing solid particles to settle under gravity, thereby achieving solid-liquid separation. A filter layer 23 is connected to the end of the sedimentation tubes 22 furthest from the separation chamber 21. The filter layer 23 further removes tiny suspended solids from the water, ensuring the clarity of the effluent. This structural design of the entire system aims to improve water purification efficiency, reduce costs, and simplify the operation process.

[0027] like Figure 3 and Figure 4As shown, to further improve water quality and ensure sufficient oxygen for fish fry growth, a supply pipe 14 is specially designed on one side of the connecting pipe 12, penetrating the outer shell 11. The other end of the supply pipe 14 is directly connected to the oxygen generator to directly deliver oxygen to the water, increasing the dissolved oxygen content and promoting the growth and development of the fish fry. Simultaneously, a fan blade 25, centered on itself and distributed around the separator, is connected inside the separation chamber 21 via a fixed shaft 24. This design allows the fan blade 25 to tilt at a certain angle towards the inlet pipe 1 when water flows through, effectively blocking and dispersing the water flow. This allows the water to tumble fully within the separation chamber, increasing the contact area and time between the water and the sedimentation pipe 22 and the filter layer 23, thereby improving solid-liquid separation and filtration efficiency. This structural design not only optimizes the water purification process but also reduces space occupation and operational complexity through an integrated system, lowering maintenance costs and labor intensity, making the entire water purification and circulation device more efficient, energy-saving, and easy to manage.

[0028] In operation, the water to be treated is first introduced into the system through the inlet pipe 1. A purification device 2 is fitted onto one end of the inlet pipe 1, forming a sealed water flow path. Next, the water enters the separation chamber 21, located inside the purification device 2, which is used for the initial separation of solid impurities in the water. Subsequently, sedimentation pipes 22, evenly distributed above the separation chamber 21, guide the water flow, causing solid particles to settle under gravity, achieving solid-liquid separation. The settled water continues to flow to the end of the sedimentation pipe 22 furthest from the separation chamber 21, contacting the filter layer 23. The filter layer 23 further removes tiny suspended solids from the water, ensuring clear effluent. Simultaneously, an outer shell 11 is fitted onto the outside of the separation chamber 21, penetrated by the inlet pipe 1. The outer shell 11 furthest from the separation chamber 21... The end is connected to the water storage tank 13 via an arched connecting pipe 12 to store purified water. In addition, one side of the connecting pipe 12 is provided with a supply pipe 14 that penetrates the outer shell 11. The other end of the supply pipe 14 is connected to an oxygen generator to directly deliver oxygen to the water, increase the dissolved oxygen content in the water, and promote the growth and development of fish fry. Finally, inside the separation tank 21, fan blades 25 are connected to the surrounding area via a fixed shaft 24. The fan blades 25 are tilted at a certain angle towards the water inlet pipe 1 to effectively block and disperse the water flow, so that the water can tumble fully in the separation tank, increase the contact area and time between the water and the sedimentation pipe 22 and the filter layer 23, and improve the solid-liquid separation and filtration efficiency. The entire device has a compact structure, is easy to operate, reduces resource consumption and labor intensity, improves water purification efficiency, simplifies the operation process, and realizes efficient water purification and recycling.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
