Description

Technical Field

[0002] Chinese mitten crabs are widely distributed and are found in provinces along the Bohai Sea, the Yellow Sea, and the East China Sea. They are found in abundance in the Yangtze River Basin from Chongming to the eastern part of Hubei. Chinese mitten crabs often live in burrows on the muddy banks of rivers, lakes, and ponds, hiding during the day and coming out at night. They feed on animal carcasses or grains. Nowadays, they are also intensively raised indoors to ensure production and quality, and to achieve higher production value.

[0003] During artificial breeding, due to the absence of other links in the ecosystem, eutrophication of the water body is likely to occur during the breeding process, causing water pollution and affecting the growth of crabs.

The existing treatment method generally adopts a circulating filtration method, but the overall circulation is relatively simple, and the uneaten feed cannot be separated, increasing the feeding cost.

[0061] The implementation principle of the embodiment of the present application is:

[0062] When working, crabs are cultured in the breeding pond 02. During the breeding process, crabs are fed and metabolized. Metabolites enter the water body, making the water body eutrophic after a certain period of time. At this time, the valve on the leakage hole 03 is opened to allow the water in the breeding pond 02 to enter the collection box 39 through the leakage hole 03 for collection. Solid waste is concentrated at the bottom of the breeding pond 02 by gravity, making the collection and discharge faster and more stable.

[0063] The liquid entering the concentration box 39, then through the action of gravity, enters the mixing chamber 36 along the guide pipe 38. The guide pipe 38 is connected with a one-way valve to prevent the fluid from flowing back. After entering the mixing chamber 36, the liquid enters the operation box 43 through the guide pipe 35, and then is pumped by the sewage pump 49, and is sprayed onto the screening plate 53 through the lifting pipe 51. The synchronous power component 60 works, thereby causing the flywheel 58 to rotate, driving the swing rod 57 to swing, so that the screening plate 53 shakes, speeding up the screening, and the larger feed is intercepted on the screening plate 53, and then discharged through the discharge pipe 21. The smaller debris, excrement, residue, etc. fall to the bottom of the operating box 43, and are then extracted by the sewage pump three 55 and enter the filter two 54 for re-filtration. After the sewage is filtered, it enters the distinction box one 47, and is then pumped by the sewage pump one 45 and filtered again by the filter one 46, and enters the mixing cylinder 41 through the guide tube three 42, and further passes through the follower ring 18 and the rotating tube 19, and enters the mixing cylinder 13, and further passes through the conducting tube 10, the sleeve ring one 09, the telescopic tube 06, the floating bar 05, and the follower sheet 17 to re-enter the water body for circulation.

[0064] During the circulation process, the corresponding flocculants, disinfectants or other necessary medicines can be filled in the medicine box 24 as needed. When necessary, they can be pumped through the extraction pump 29 and then enter the reflux pipe 28 with fluid through the sleeve ring 2 30 for addition. The medicine can also be sent to the functional box 33 through the quantitative tube 32 and then pumped through the extraction pump 3 34 for preliminary addition. When the fluid flows, the material in the storage box 11 can be entered into the mixing barrel 13 through the extraction pump 1 12 as needed, and then added through the guide tube 10 and the follower plate 17 along the flow of the internal fluid. At the same time, the slow-release agent in the slow-release box 07 can enter the fluid through the installation sleeve 14 for slow release to meet the needs of work.

[0065] During the treatment process, the air pump 37 can be used for preliminary aeration to pressurize the fluid and provide a certain disturbance, so as to separate the larger particles that may be stuck together and ensure the subsequent separation. At the same time, the air pump 40 is used to pump the gas into the mixing tube 41 to supplement oxygen, avoid hypoxia in the water, and ensure the subsequent breeding.

[0066] During the water circulation process, the thrust of the fluid flow causes the entire rotating tube 19 to rotate, and further through transmission, drives the extension tube 08 and the floating bar 05 to rotate. The floating bar 05 floats on the water surface and hits the foam. At the same time, the follower sheet 17 assists in removing the foam. At the same time, the water body is disturbed during the rotation process, increasing the oxygen content of the water body. The follower sheet 17 is located at the bottom of the water. During the circulation process, the water flow impact is reduced, noise and bubbles are reduced, and at the same time, a stable and uniform supply of medicines can be guaranteed.
