Description

Technical Field

[0001] The invention specifically relates to the technical field of fish breeding and reproduction, and in particular to a fish breeding and reproduction system that simulates a marine environment. Background Art

[0002] Since the marine environment includes many factors, such as water temperature, which varies with seasons, ocean currents, depth and other factors, and salinity, which also changes due to sea location, freshwater injection and other conditions, traditional marine fish breeding systems are often unable to accurately simulate the complex and changeable conditions of the marine environment. Moreover, the cleanliness of the ocean is also very important for fish reproduction. If there are too many impurities such as fish bait and fish feces in the water, it will cause a certain stimulation to the fish eggs and is not conducive to the fish's gonadal development and reproductive behaviors such as ovulation and fertilization.

[0003] In the existing simulated marine environment aquaculture and breeding systems, the filter material type of the filtration system is single or the amount of filter material is insufficient to effectively filter out the remaining bait and excrement in the water, making it difficult to effectively remove harmful substances, odors and colors in the water. Some filtration systems even only use simple filter cotton, which cannot effectively treat substances such as ammonia nitrogen, and the filter cotton replacement cycle is relatively frequent. Summary of the invention

[0058] Specifically, the microbial filter cartridge 104 uses ceramic rings, biochemical balls, etc. This layer mainly provides a place for beneficial microorganisms such as nitrifying bacteria to attach. These bacteria can decompose harmful substances such as ammonia nitrogen in the water and convert them into relatively harmless substances, providing healthy waters for fish reproduction;

[0059] The activated carbon filter cartridge 102 is mainly used to absorb pigments, odors and other residual chemicals in water.

[0065] In this embodiment, the secondary filter press assembly includes:

[0066] Two spacers 118 are provided, which are fixed on the filter cartridge and the lower sealing seat respectively. The opposite end surfaces of the two spacers 118 are provided with a plurality of limiting slide grooves in a circumferential array, and a slider 119 is adapted to slide in each limiting slide groove;

[0068] and a cotton filter cartridge 121, which is disposed between the two partitions 118, both ends of the cotton filter cartridge 121 are connected to the two partitions 118 by elastic sealing rings 120, so that water can only be filtered out from the cotton filter cartridge 121, and the inner wall of the cotton filter cartridge 121 is connected to each pressure rod 122;

[0069] Specifically, when the forward and reverse motors drive the screw rod 112 to rotate counterclockwise, under the limiting effect of each pressure rod, the internal threaded tube and the screw rod 112 rotate in coordination with each other, and move upward in a straight line, and pull the inclined rod 111 to increase its inclination. However, when the length of the inclined rod 111 remains unchanged, each pressure rod 122 moves toward the direction of the internal threaded tube, thereby compensating for the inclination requirement of the inclined rod 111, and achieving a squeezing effect by reducing the volume of the filter cotton cylinder, thereby performing a second pressure filtration on the water body therein, and the squeezing effect can speed up the filtration speed, and can avoid the clogging of the filter cotton through the pressurization effect, thereby continuously ensuring the cleanliness of the water body in the aquaculture tank;

[0070] Moreover, when the internal threaded pipe moves upward, it drives the first-stage filter press assembly to push upward to filter out the newly entered water, so that larger particles of impurities in the water remain in the inner sealing ring, thereby reducing the physical filtration burden of the filter cotton cartridge;

[0071] When the forward and reverse motor drives the screw 112 to rotate clockwise, similarly to the above, the secondary filter press assembly and the primary filter press assembly return to their original positions.
