Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a circulating water aquaculture device for fish farming. Background Art

[0002] After retrieving the patent document with the publication number of CN213127657U, this patent document filters impurities in water by setting a filter box, a fish separating net, a first filter layer, a second filter layer and a third filter layer, improving the survival rate of fish in this device. The filtered water in the inner cavity of the fishpond is pumped out by a water pump and put back into the fishpond to realize the recycling of water.

[0003] When filtering, dirt such as food residues and excreta will automatically precipitate to the bottom of the fishpond under the action of gravity and then be discharged. There is also a mixture formed by some dirt and other impurities that will adhere to the inner wall of the fishpond to form an adhesion layer, which will affect the water quality in the fishpond. And when feeding, the fish food is randomly and concentratedly scattered at a certain place in the fishpond, so that the fish food sinks to the bottom of the fishpond before being eaten up, resulting in an increase in excess food residues and an increase in the filtration burden, affecting the health of the fish.

By driving the rotating plate 404 to rotate through the first motor 402, the brush plates 403 are driven to rotate, thereby cleaning the adhesion layer formed by the dirt on the inner wall of the breeding barrel 1.

[0030] In this embodiment: The feeding mechanism 5 includes two material distribution rods 503. The rotating plate 404 is provided with two inner grooves symmetric about the first motor 402. Storage granaries 501 are fixed to the tops of the two inner grooves. The two material distribution rods 503 are respectively rotatably connected in the two inner grooves.

The filtered water is conveyed into the water delivery pipe 301 through the water pump 302 and then flows into the breeding barrel 1 from the water outlet end of the water delivery pipe 301. By extracting the filter rack 305, the first filter layer 306, the second filter layer 307, and the third filter layer 308 are cleaned.

[0032] Working principle: Start the first motor 402 to drive the rotating plate 404 to rotate. The rotating plate 404 drives the brush plates 403 on both sides to rotate in the breeding barrel 1. The upper half of the brush plate 403 cleans the dirt on the inner wall of the upper half of the breeding barrel 1, and the lower half of the brush plate 403 cleans the dirt on the inner wall of the lower half of the breeding barrel 1, so that the brush plate 403 comprehensively cleans the inner wall of the breeding barrel 1. Start the second motor 502 to drive the material distributing rod 503 to rotate. During the rotation, the fish food in the storage granary 501 is quantitatively scattered into the breeding barrel 1. Pull out the water blocking plate 304 to the other side. The dirt cleaned and the remaining fish food feces flow into the filter box 303 along with the water. The water in the breeding barrel 1 is filtered through the first filter layer 306, the second filter layer 307 and the third filter layer 308. Start the water pump 302 to pump the filtered water from the filter box 303 back into the breeding barrel 1 through the water delivery pipe 301 to realize water circulation. After filtering for a certain period of time, push the water blocking plate 304 to one side, pull out the filter rack 305, the first filter layer 306, the second filter layer 307 and the third filter layer 308 for cleaning and then put them back for recycling.
