Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, in particular to a biological bait filter screen. Background Art

[0002] Factory-scale recirculating aquaculture is a new aquaculture model with numerous advantages, including low water consumption, small footprint, minimal pollution, fewer diseases, and high resource utilization. It represents advanced productivity in aquaculture and is a key development direction for future fisheries. Factory-scale seedling production is a highly efficient method for aquatic seedling propagation, offering advantages such as controllable water quality and improved resistance to environmental fluctuations.

[0003] Newly hatched fry often use biological bait as their starter feed. When feeding biological bait artificially, newly hatched fry are more likely to consume smaller bait, while larger fish prefer larger bait. If unfiltered biological bait is fed directly to fry at different growth stages, fish of different sizes will selectively choose the bait that is more palatable, resulting in waste. Furthermore, there is currently a lack of equipment on the market that can filter and separate biological bait by size.

[0004] Therefore, a biological bait filter screen is now proposed to solve the problem of filtering and separating biological baits of different sizes and feeding them to fry at different growth stages. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3, the utility model provides a technical solution: a biological bait filtering screen, comprising a cylinder 1 and a screen 2;

[0020] The mesh screen 2 is composed of a stainless steel mesh frame 21 and a flexible filter screen 22. The stainless steel mesh frame 21 is connected to the interior of the cylinder 1 by a hemispherical hook. The flexible filter screen 22 has filtering properties, allowing smaller biological bait to pass through while intercepting larger biological bait. The flexible filter screen 22 is flatly attached to one side of the stainless steel mesh frame 21, which facilitates the stable and multi-directional passage of smaller biological bait through the mesh screen 2. The flexible filter screen 22 is equipped with multiple filter screens of different mesh sizes according to the volume of the biological bait to be screened. By replacing the flexible filter screens 22 of different mesh sizes, the mesh screen 2 can achieve multi-stage filtration of the biological bait.

[0021] A waterproof light 3 is fixedly provided at the bottom of the barrel 1. The light emitted by the waterproof light 3 is conducive to utilizing the phototaxis of the biological bait to attract it to swim to the bottom of the barrel, thereby accelerating the filtering effect.

[0022] The bottom of the cylinder 1 is provided with a water outlet 4, which can be directly connected to the factory circulating water where the juveniles are located. The water outlet 4 is conducive to directly feeding the small volume of biological bait screened out to the juveniles;

[0023] The upper cover of the cylinder 1 is connected to the upper cover 5, and a motor frame 6 is welded to one side of the upper cover 5. A motor 7 is fixedly installed on the upper part of the motor frame 6. A motor protection cover 12 is provided on the outer side of the motor 7. A transmission shaft 8 is connected to one side of the motor 7. An impeller 9 is fixedly installed on one side of the transmission shaft 8. The motor 7 drives the transmission shaft 8 to rotate, thereby rotating the impeller 9 on the transmission shaft 8. The rotation of the impeller 9 is conducive to accelerating the flow rate of water, pushing the biological bait to move with the water flow, thereby accelerating the filtering effect;

[0024] A water inlet 10 is provided on the upper cover 5 and is located in front of the impeller 9. The water inlet 10 can be connected to the water area where the biological bait is located. This is beneficial for reducing the pressure on one side of the water inlet 10 in the barrel under the action of the rotation of the impeller 9, so that the biological bait is continuously drawn into the barrel 1 along with the water flow.

[0025] A bracket 11 is provided on the outside of the cylinder 1, which plays a supporting and protective role for the cylinder 1 and its accessories;

[0026] Working principle: connect the water inlet 10 to the water area where the biological bait is located, connect the water outlet 4 to the factory circulating water where the juvenile fish are located, start the motor 7, and the motor 7 drives the impeller 9 to rotate, and the water mixed with the biological bait is drawn into the cylinder 1 from the water inlet 10. Due to the action of gravity and the attraction of the waterproof lamp 3 at the bottom of the cylinder 1, the biological bait swims downward. At this time, the rotation of the impeller 9 also produces a downward thrust on the water flow, thereby accelerating the swimming speed of the biological bait. When the biological bait swims to the edge of the mesh screen 2, the smaller biological bait will smoothly pass through the flexible filter screen 22, and then flow out from the water outlet 4 with the water flow into the factory circulating water where the juvenile fish are located, so as to directly feed the smaller fry. After the biological bait is filtered, the mesh screen 2 is removed from the cylinder 1, and the biological bait in the mesh screen 2 is fed to the larger fry, thereby achieving the filtering effect of the biological bait filtering mesh screen.
