DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. The methods used in the present utility model are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercial products unless otherwise specified.

[0018] Depend on Figure 2 , Figure 3 As shown, the utility model provides a freshwater aquaculture water circulation system, which is provided with a water tank 1 and a water storage tank 9, the water storage tank 9 is connected to a drain pipe 13, the drain pipe 13 is connected to a filter 14, a filter screen 12 is installed in the filter 14, and a valve 15 is installed on the drain pipe 13; the drain pipe 13 is provided with a waste outlet 16, and the waste outlet 16 is arranged between the filter screen 12 and the valve 15; the waste outlet 16 is sealed and connected to a waste pipe 17, and the waste pipe 17 is detachably and sealedly connected to a sealing cover 18.

[0019] When the utility model is in use, the drain pipe 13 is first closed through the valve 15, and it is best to close the water pump 6 at the same time; then the sealing cover 18 is opened, and the waste pipe 17 is preferably connected to an external pipeline so that the waste water can be discharged into the waste water bucket through the pipeline; then the external flushing pipe is sealed and connected to the pipe mouth of the water outlet pipe of the filter 14; the external flushing pipe is connected to the external water pump.

[0020] After the preparation work is completed, the external water pump is started, and the extracted clean water enters the filter 14 through the external flushing pipe to flush the filter screen 12 in the filter 14. After the food residues and excrement on the filter screen 12 are flushed away, the waste water formed is discharged successively through the waste outlet 16 and the waste pipe 17. The cleaning of the food residues and excrement on the filter screen 12 is completed, and the whole process saves time and labor, and will not pollute the aquaculture water in the water tank 1.

[0021] After the filter screen 12 is cleaned and the cleaning process is completed, the external water pump is turned off, and after all the water in the filter 14 flows out through the waste pipe 17, the sealing cover 18 is used to seal the waste pipe 17, the external flushing pipe is separated from the outlet pipe of the filter 14, the valve 15 is opened, the water pump 6 is started, and the aquaculture water circulation process is restarted. The whole process is convenient and fast, saving time and effort.

[0022] As a preferred embodiment, Figure 2 , Figure 4 As shown, the outlet pipe of the filter 14 is sealed and connected with a drainage ring device, and the drainage ring device is provided with a connecting pipe 19 and a drainage ring assembly 20; the connecting pipe 19 is a hollow tubular structure with two ends open, and one end of the connecting pipe 19 is sealed and connected with the pipe mouth of the outlet pipe of the filter 14; the drainage ring assembly 20 is a chain structure, which is provided with a plurality of drainage rings 21, and the drainage rings 21 are annular structures, and the drainage rings 21 are interlocked with each other to form a chain structure; the upper end of the drainage ring assembly 20 is connected to the inner wall of the connecting pipe 19, and the lower end of the drainage ring assembly 20 extends into the water tank 1. When the drainage device is in use, the lower end of the drainage ring assembly 20 hangs on the aquaculture water surface or in the water surface in the water tank 1, and the aquaculture water discharged from the outlet pipe of the filter 14 enters the aquaculture water in the water tank 1 through the connecting pipe 19 and the drainage ring assembly 20 in turn. Due to the drainage effect of the drainage ring assembly 20, the aquaculture water discharged from the outlet pipe of the filter 14 will not fall directly from a high place into the aquaculture water in the water tank 1, avoiding the generation of water splashes that may scare the fish and affect their normal growth.

[0023] In addition, when flushing with water to clean the food residues and excrement on the filter screen 12, it is only necessary to remove the drainage ring assembly 20 and seal the external flushing pipe with the connecting pipe 19, which saves time and effort. The other contents are the same as the above operation and will not be repeated.

[0024] As a further preferred embodiment, Figure 2 , Figure 4 As shown, a connecting piece 22 is connected in the connecting pipe 19, and the upper end of the drainage ring assembly 20 is connected to the connecting piece 22. It is best to detachably connect the upper end of the drainage ring assembly 20 to the connecting piece 22 through a buckle, so as to facilitate the replacement of the connecting piece 22.

[0025] As a further preferred embodiment, Figure 2 , Figure 4 As shown, the connecting pipe 19 is a circular tubular structure, the connecting piece 22 is a straight rod structure, the two ends of the connecting piece 22 are respectively connected to the inner wall of the connecting pipe 19, and the connecting piece 22 coincides with a diameter of the circular cross section of the connecting pipe 19, and the upper end of the drainage ring assembly 20 is connected to the middle of the connecting piece 22. The aquaculture water discharged from the outlet pipe of the filter 14 is discharged more smoothly, and the water flow is more soothing and easy to control.

[0026] As a preferred embodiment, Figure 2 As shown, a baffle 2 is installed inside the water tank 1, and a drainage channel 3 is opened at the bottom of the water tank 1. The baffle 2 is inclined, and its lowest end faces the direction of the drainage channel 3. During the drainage process, food residues and excrement falling into the bottom of the water tank 1 can flow into the drainage channel 3 along the baffle 2 inclined downward and along the direction of water flow.

[0027] The utility model provides a freshwater aquaculture water circulation system. When cleaning the filter screen 12, it is only necessary to let external clean water enter the water inlet pipe through the filter 14 to flush the filter screen 12 in the filter 14. After the food residues and excrement on the filter screen 12 are flushed away, the formed waste water is discharged through the waste outlet 16 and the waste pipe 17 in turn. There is no need to dismantle the entire filter 14, which saves time and effort. The entire cleaning process is carried out in the sealed filter 14, and the aquaculture water in the water tank 1 will not be polluted.
