fourth, ozone is conveyed into the clean water cavity 62 through the disinfection pipe 610, and water in the clean water cavity 62 is treated by utilizing the powerful oxidation effect of the ozone, so that most harmful microorganisms such as bacteria and viruses can be killed, the turbidity of the water can be reduced, the dissolved oxygen amount in the water can be increased, ammonia nitrogen in the water can be oxidized and removed, the hatching rate is improved, and meanwhile, the occurrence rate of seedlings can be reduced;
fifthly, the water in the clear water cavity 62 is circularly transported to the box body 1 for culturing the fishes and the shrimps through the first operation, so that the water can be recycled, the water can be saved, the incubation cost is reduced, the water quality after the filtering treatment is good, the incubation of the fishes and the shrimps is facilitated, the incubation efficiency and the incubation effect are improved, and the death of the fishes and the shrimps is avoided;
sixthly, starting the motor 134, so that the driving gear 133 drives the driven gear 132 and the filter frame 2 to rotate on the base 13, and in the rotation process of the filter frame 2, the filter screen 22 continuously moves relatively to water in the box body 1, at the moment, water flow can continuously wash the surface of the filter screen 22, and the phenomenon that fish, shrimp eggs or egg shells adhere to the surface of the filter screen 22 is avoided, so that the filter screen 22 is blocked to cause overflow escape accidents in the box body 1, the hatching quantity of the fish and the shrimp is ensured, the hatching efficiency is improved, meanwhile, the filter screen 22 rotates, the water flow around the filter screen 22 can be outwards diffused under the action of pushing force and centrifugal force, so that the fish, shrimp eggs or egg shells in the water can be far away from the filter screen 22, and the risk of blocking caused by the adhesion of the fish, shrimp eggs or egg shells to the surface of the filter screen 22 is reduced;
seventh, oxygen is provided to the aeration pipe 52 by using the air pump in the aeration box 3, and after high-pressure oxygen enters the aeration pipe 52, part of the high-pressure oxygen is sprayed into the water in the frame 21 from the air outlet 521, so that the dissolved oxygen in the water is increased;
eighth, the high-pressure oxygen in the other part of the aeration pipe 52 enters the cavity 531 of the aeration disc 53 through the connecting pipe 522, and finally is sprayed into the water of the box body 1 through the through holes on the air guide plate 532, so that the oxygen content of the water is increased, and the oxygen content of the water is further increased, and the bubbles can blow away eggs or egg shells which are carelessly adhered to the filter screen 22 in the process of entering the box body 1 through the filter screen 22, so that the risk of blocking the filter screen 22 is further reduced, and part of the bubbles can adhere to the surface of the eggs or egg shells in the process of vibration, wherein the bubbles can be separated from the surface of the egg shells by pushing the eggs or egg shells, and the air shells can be separated from the box body 1 by pushing the eggs and the egg shells;
and ninth step, until the eggs of the fish and the shrimp in the box body 1 are fully hatched into fish and shrimp seedlings, finally taking out the fish and the shrimp seedlings from the seedling collecting port 14 of the box body 1, wherein the structure is simple, the operation is convenient, and the oxygen bubbles can be suspended in the water by adopting a multiple structure and are not easy to float and crack, so that the oxygen content in the water is increased, and the hatching efficiency is improved.
The foregoing is merely illustrative of specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the design concept shall fall within the scope of the present invention.
