Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine aquatic organism breeding technology, and in particular to a small-scale marine ornamental aquatic organism isolation and quarantine special circulating water system. Background Technology
[0002] Marine ornamental fish, as a mainstay of the marine aquarium industry, have a huge demand in the domestic aquarium market. Currently, most marine ornamental fish are caught in the wild, with a small number of species bred in captivity also having some artificial breeding sources. Wild-caught organisms carry a significant risk of disease, and disease infection plays a decisive role in the survival and health of the organisms. Therefore, most aquariums, importers, and aquarists quarantine imported marine ornamental fish. However, there is currently no dedicated recirculating aquaculture system for quarantine in China, which is a gap in the current marine ornamental aquarium aquaculture technology. Therefore, constructing a small-scale recirculating aquaculture system for the quarantine of marine ornamental fish is one of the important issues that the ornamental aquarium industry needs to address. Summary of the Invention
[0003] This invention aims to address the shortcomings of existing technologies by providing a small-scale marine aquarium biological quarantine and recycling system.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a small-scale marine aquarium biological quarantine and isolation circulating water system, comprising a tank system, a water circulation system, and a filtration system. The tank system includes a partitioned tank, an aluminum support frame, a bottom tank, and acrylic partition plates. The partitioned tank is installed on top of the aluminum support frame, and the bottom tank is installed at the bottom of the aluminum support frame. The partitioned tank has several layers from top to bottom, with three tank cavities in each layer. Each tank cavity has an overflow trough on one side and several compartments for placing individual biological organisms formed by interlocking acrylic partition plates on the other side. The overflow troughs in adjacent tank cavities are staggered. The water circulation system includes a circulating water pump, a water replenisher, and a circulation pipeline. The circulating water pump, water replenisher, and filtration system are respectively installed in the bottom tank, and the circulating water pump is connected to the partitioned tank and the bottom tank through the circulation pipeline to achieve water circulation and filtration purification.
[0005] In particular, the acrylic partition plate has several through holes.
[0006] In particular, the split cylinder body is set with three layers, and the inner wall of the bottom cylinder has five sets of staggered partitions, and the bottom cylinder is divided into six spaces by the partitions.
[0007] Specifically, the circulating water pump is installed at the bottom of the space at one end of the bottom cylinder, and the water replenisher is installed on the inner side wall of the space. The circulation pipeline includes an inlet water pipeline, a outlet water pipeline, and an overflow pipe. The inlet water pipeline is connected to the outlet of the circulating water pump, and after passing through the bottom cylinder and the aluminum support, the inlet water pipeline is laid on the top of the partitioned cylinder and connected to the compartment at the end of each cylinder cavity away from the overflow trough. The top of the overflow pipe is connected to the overflow trough, and the bottom is connected to the adjacent compartment below. The lowest overflow pipe extends into the aluminum support and connects to the outlet water pipeline. The outlet of the outlet water pipeline is connected to the space at the other end of the bottom cylinder. An overflow screen is provided on the top of the overflow pipe.
[0008] Specifically, the filtration system includes a protein skimmer and filter media. The protein skimmer is installed in the space immediately adjacent to the drain outlet, and the filter media is installed in the remaining three spaces.
[0009] Specifically, each cylinder has 20-30 compartments.
[0010] The beneficial effects of this utility model are: This utility model provides the necessary life-sustaining conditions (including water quality conditions, filtration conditions and a stable water environment), efficient isolation space and reasonable management and maintenance system for the isolation and quarantine of ornamental aquatic organisms. Under the premise of ensuring good water quality conditions in the water body where the organisms are located, the water body is divided into as many independent spaces as possible, which can isolate and quarantine ornamental aquatic organisms more efficiently, densely and stably.

[0015] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0017] like Figures 1-3As shown, a small-scale marine aquarium biological quarantine and isolation circulating water system includes a tank system, a water circulation system, and a filtration system. The tank system includes a partitioned tank 1, an aluminum support 2, a bottom tank 3, and acrylic partition plates 4. The partitioned tank 1 is installed on top of the aluminum support 2, and the bottom tank 3 is installed at the bottom of the aluminum support 2. The partitioned tank 1 has several layers from top to bottom, and each layer has three tank cavities. Each tank cavity has an overflow channel 5 on one side and several compartments 15 formed by interlocking acrylic partition plates 4 on the other side for placing individual biological organisms. The overflow channels 5 in adjacent tank cavities are staggered. The acrylic partition plates 4 have several through holes to facilitate water flow and fill each compartment 15.
[0018] Specifically, the partitioned tank 1 is the main space for the isolation and quarantine of aquarium organisms. The partitioned tank 1 has three layers, with three tank chambers in each layer. Each tank chamber contains 20-30 compartments 15. Acrylic partitions 4 maximize the partitioning and management of the water, facilitating isolation, quarantine, and maintenance. Each compartment 15 holds an individual organism, making full use of the water space for isolation and quarantine work. The acrylic partitions 4 also effectively prevent organisms from attacking each other and reduce the probability of disease transmission to a certain extent, thus enabling more efficient and stable isolation and quarantine of aquarium organisms. The overflow trough 5 is used to effectively maintain the water level in each tank layer.
[0019] The water circulation system includes a circulating water pump 8, a water replenisher 11, and circulation pipelines. The circulating water pump 8, water replenisher 11, and filtration system are respectively installed in the bottom tank 3. The circulating water pump 8 is connected to the partitioned tank 1 and the bottom tank 3 through the circulation pipelines to achieve water circulation and filtration purification. The circulating water pump 8 is used for water circulation in the circulation system, and the water replenisher 11 is used to maintain the water level, water volume, and salinity of the circulation system.
[0020] Specifically, the aluminum support 2 is used to support the partitioned cylinder 1 and place the bottom cylinder 3, and has the same length and width as the partitioned cylinder 1; the bottom cylinder 3 is the space where the water circulation system and the filtration system are located, and is placed inside the aluminum support 2. The inner wall of the bottom cylinder 3 is provided with five sets of staggered partitions 14, and the bottom cylinder 3 is divided into six spaces by the partitions 14 for water circulation and water filtration.
[0021] A circulating water pump 8 is installed at the bottom of a space at one end of the base cylinder 3. A water replenisher 11 is installed on the inner side wall of this space. The circulation pipeline includes an upper water pipe 9, a lower water pipe 10, and an overflow pipe 7. The upper water pipe 9 is connected to the outlet of the circulating water pump 8. After passing through the base cylinder 3 and the aluminum support 2, the upper water pipe 9 is laid on the top of the partitioned cylinder body 1 and connected to the compartment 15 at the end of each cylinder cavity away from the overflow trough 5. The top of the overflow pipe 7 is connected to the overflow trough 5, and the bottom is connected to the adjacent compartment 15 below. The lowest overflow pipe 7 extends into the aluminum support 2 and connects to the lower water pipe 10. The outlet of the lower water pipe 10 is connected to the space at the other end of the base cylinder 3. An overflow screen 6 is provided on the top of the overflow pipe 7. The upper and lower layers of the partitioned cylinder body 1 are connected by overflow. The overflow screen 6 is used to allow water to pass through and overflow to the lower cylinder body, while simultaneously replenishing the oxygen content in the water in a small amount.
[0022] The filtration system includes a protein skimmer 12 and filter media 13. The protein skimmer 12 is installed in the space immediately adjacent to the outlet of the drain pipe 10, and the filter media 13 are installed in the remaining three spaces. The protein skimmer 12 discharges organic debris, proteins, and other components from the circulation system, while the filter media 13 is the main site for microbial decomposition and other related processes in the circulation system. The filtration system effectively reduces large particulate organic matter in the water and ensures that nutrients are maintained at a stable low level, ensuring a good living environment and water quality for organisms during quarantine.
[0023] In operation, the ornamental organisms to be quarantined are placed individually in compartment 1. The water in the circulation system flows from the top compartment of the partitioned tank 1 through the overflow pipe 7, passing through three layers of tanks in sequence, and finally flowing from the drain pipe 10 to the bottom tank 3. The water then flows through the protein skimmer 12 and filter media 13 in the bottom tank 3, and is finally pumped by the circulating water pump 8 through the water inlet pipe 9 back to the top compartment of the partitioned tank 1, thus completing the entire water circulation process. The water replenishment device 11 is used to maintain the water volume and salinity of the circulation system at a constant level.
[0024] This invention provides the necessary life-sustaining conditions (including water quality, filtration, and a stable aquatic environment), efficient isolation space, and a reasonable management and maintenance system for the quarantine of ornamental aquatic organisms. While ensuring good water quality in the water body where the organisms are located, it divides the water body into as many independent spaces as possible, enabling more efficient, high-density, and high-stability quarantine of ornamental aquatic organisms.
