[0036] The present utility model provides a nereis temporary culture and purification device, which is used to solve the technical problems of incomplete mud spitting, low water change rate, and easy breeding of pathogenic microorganisms and pathogens in the prior art.
[0037] In order to make the utility model purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0038] Please refer to Figures 1 to 4 , a nereis temporary culture and purification device provided by this embodiment includes: a culture tank 1 for culturing nereis, a water pump 7 for pumping water, a sedimentation tank 2 for precipitating solid debris in water, and a purification component 3 for purifying water;
[0039] The culture tank 1, the sedimentation tank 2, and the purification component 3 are sequentially connected through pipelines to form a circulating water path, and a water pump 7 is connected to the pipeline of the circulating water path. The water pump 7 is used to drive water to flow in the circulating water path;
[0040] The culture tank 1 has a tank opening 10 and a tank bottom 11. Along the direction from the tank opening 10 to the tank bottom 11, the tank bottom 11 gradually narrows, and a sewage discharge outlet 13 for discharging nereis excrement is provided at the bottom of the tank bottom 11;
[0041] A filter screen 12 is provided in the culture tank 1. The filter screen 12 covers the tank bottom 11, and the filter screen 12 is used to separate nereis from nereis excrement.
[0042] In actual application, the water pump 7 is turned on, and under the action of the water pump 7, water will circulate among the culture tank 1, the sedimentation tank 2, and the purification component 3. When the aquaculture personnel place nereis on the filter screen 12, the excrement of the nereis will fall from the mesh holes of the filter screen 12 to the bottom 11 of the tank. The nereis excrement moves along the bottom 11 of the tank to the sewage outlet 13, and the sewage outlet 13 will discharge the water containing nereis excrement into the sedimentation tank 2 for sedimentation. The supernatant of the sedimentation tank 2 then flows into the purification component 3 for purification, and then circulates back into the culture tank 1 to complete the purification and circulation of the nereis culture water.
[0043] After adopting such a structural arrangement, the above-mentioned embodiment has at least the following advantages: First, circulating water is provided in the nereis culture device. On the one hand, it increases the water replacement rate of the water body in the culture tank 1. On the other hand, according to existing research, nereis can respond to tidal alternation (flowing water) through a series of movement behaviors, including pumping water behavior. During the pumping water behavior, nereis can spit out the sediment in its body more thoroughly. Therefore, the flowing water will make the nereis in the culture tank 1 spit out mud more thoroughly. Second, the nereis is cultured on the filter screen 12, and the filter screen 12 can separate the nereis from its excrement. The nereis excrement will fall from inside the filter screen 12 to the bottom 11 of the culture tank 1 and move along the inclined surface of the bottom 11 of the culture tank 1 towards the water outlet, so that it can be discharged smoothly. This structure is conducive to the convenient collection and removal of nereis excrement, avoiding the long-term stay of nereis excrement in the culture tank 1 and reducing the possibility of the growth of pathogenic microorganisms and pathogens.
[0044] In a specific implementation manner, a feasible structure of the culture tank 1 is further provided. The culture tank 1 has four tank walls and a bottom 11, and a filter screen 12 is provided inside the culture tank 1.
[0045] Referring to Figure 5 and Figure 6 the structural schematic diagram of the culture tank 1 in, a water inlet pipeline is provided at the top of the culture tank 1. The water inlet pipeline is erected on the tank opening 10 of the culture tank 1. The sewage outlet 13 at the bottom of the culture tank 1 is connected to a water outlet pipeline. Through such an arrangement, the water in the water inlet pipeline can fall into the culture tank, and the water and oxygen in the air fall into the water body of the culture tank, increasing the oxygen content in the water body of the culture tank 1 and improving the survival ability of nereis.
[0046] The culture tank 1 is formed by four tank walls and a bottom 11 with a sewage outlet 13. The filter screen 12 is provided inside the culture tank 1. The four peripheral walls of the filter screen 12 are respectively abutted and fixed to the four tank walls to prevent nereis from slipping away between the filter screen 12 and the tank walls. In actual application, when water is introduced into the culture tank 1 and covers the filter screen 12, the nereis is cultured on the filter screen 12.
[0047] Among them, the connection method between the tank wall and the filter screen 12 includes, but is not limited to, detachable connection methods such as snap connection and bolt screwing, nor is it limited to fixed connection methods such as bonding and welding. The different connection methods depend on the different maintenance methods, and those skilled in the art can choose according to their actual needs.
[0048] It should be noted that the materials used for the tank wall and the tank bottom 11 of the breeding tank 1 are preferably PP materials (polypropylene). Of course, those skilled in the art can choose other common tank materials or wall materials in the breeding industry.
[0049] Please refer to Figure 5 and Figure 6 , based on the above embodiments, a realizable structure of the filter screen 12 is further provided. The filter screen 12 is horizontally arranged in the breeding tank 1. After the nereis are regularly laid on the filter screen 12, the horizontally arranged filter screen 12 can evenly spread the nereis on the filter screen 12, providing a good breeding environment for the nereis. If the filter screen 12 is inclined, it may cause the nereis to accumulate in a certain area of the filter screen 12, which is likely to affect the development of the nereis.
[0050] The mesh size of the filter screen 12 is 1 - 2 mm. This is to match the diameter size of the nereis and avoid the possibility of the nereis falling through the filter screen 12 during the breeding process. For example, when there are 300 Neanthes succinea in the breeding tank 1, the mesh diameter of the filter screen 12 is 1 mm; when there are 200 Neanthes succinea in the breeding tank 1, the mesh diameter of the filter screen 12 is 1.5 mm; when there are 150 Neanthes succinea in the breeding tank 1, the mesh diameter of the filter screen 12 is 2 mm. That is, after the mesh size of the filter screen 12 is set at 1 - 2 mm, it can prevent the nereis from falling through the filter screen 12 during the breeding of nereis.
[0051] It should be noted that the material used for the filter screen 12 is preferably PE material (polyethylene). Of course, those skilled in the art can choose other common filter screen materials in the breeding industry.
[0052] Please refer to Figure 5 and Figure 6, Based on the above embodiments, a feasible structure of the tank bottom 11 is further provided. In the direction from the tank opening 10 to the tank bottom 11, the gradually narrowing setting of the tank bottom 11 is conducive to the convenient collection and drainage of nereis excrement. Preferably, the tank bottom 11 is a V-shaped tank bottom 11. In practical applications, the V-shaped tank bottom 11 will form two opposite planes with an inclined angle. When the nereis excrement falls along the tank wall into the tank bottom 11, the nereis excrement will slide along the inclined plane to the water outlet for waste discharge, and the collection efficiency of the excrement is higher. If the tank bottom is set to be flat, only the excrement on the sewage outlet can be discharged, and it is difficult to discharge the excrement accumulated on other flat bottoms, increasing the possibility of the growth of pathogenic microorganisms and pathogens.
[0053] Of course, in some other embodiments, the tank bottom 11 can also be an arc-shaped narrowing tank bottom 11. However, after adopting the arc-shaped tank bottom 11, compared with the inclined plane being a flat surface, the sliding of the nereis excrement is not as smooth.
[0054] A plurality of sewage outlets 13 are opened at the bottom of the V-shaped tank bottom 11. Sewage outlets 13 are provided on both sides of the V-shaped tank bottom 11, and a plurality of sewage outlets 13 are evenly arranged between the two sides. In practical applications, the setting of sewage outlets 13 on both sides and in the middle of the V-shaped tank bottom 11 can ensure that the nereis excrement is quickly drained away, avoid the problem of a large accumulation of nereis excrement, effectively reduce the level of Vibrio nereis, and is more conducive to subsequent transportation and storage.
[0055] It should be understood that in addition to increasing the sewage outlet area by adding more sewage outlets 13, based on the above embodiments, a vortex can also be formed at the sewage outlet 13 to increase the sewage outlet area by using the vortex. That is, the diameter of the generated vortex is larger than the diameter of the sewage outlet 13, and the adsorption range of the vortex is larger than the adsorption range of the simple sewage outlet 13. Therefore, the vortex can adsorb water or dirt outside the sewage outlet 13, effectively increasing the sewage outlet area.
[0056] In a specific embodiment, a hollowed-out cover plate (not shown in Figure 5 and Figure 6 ) is installed in each sewage outlet 13. The hollowed-out cover plate covers the corresponding sewage outlet 13. When the water flow flows out of the sewage outlet 13 from the hollowed-out cover plate, a vortex will be formed at the hollowed-out cover plate. The adsorption range of the vortex is larger than the area range of the sewage outlet 13, increasing the sewage discharge capacity.
[0057] Furthermore, in order to control the water level of the culture tank 1, a water inlet valve (not shown in Figure 5 and Figure 6 ) is connected to the water inlet pipeline of the culture tank 1. The water inlet valve is used to control the water inflow of the water inlet pipeline; a drain valve (not shown in Figure 5 andFigure 6 (not shown in the figure), the drain valve is used to control the water discharge volume of the water outlet pipeline. In actual application, when the water inlet volume of the water inlet valve is increased and the water discharge volume of the drain valve is decreased, the aquaculture tank 1 can be maintained at a high water level state. On the contrary, when the water inlet volume of the water inlet valve is decreased and the water discharge volume of the drain valve is increased, the aquaculture tank 1 can be maintained at a low water level state. Those skilled in the art can adjust the water level height according to needs.
[0058] In some specific application scenarios, the application of multiple aquaculture tanks 1 is further provided. The nereis temporary culture and purification device further includes multiple culture racks 4, and multiple aquaculture tanks 1 are arranged on each culture rack 4, forming a culture schematic diagram as Figures 1 to 4 shown.
[0059] More specifically, the culture rack 4 is formed with multiple layers of installation spaces, and each layer of installation space is used to install an aquaculture tank 1. In actual application, a culture rack 4 is provided with multiple aquaculture tanks 1. Coupled with the setting of multiple culture racks 4, the culture space is fully utilized, and it can be widely used in large-scale indoor nereis culture.
[0060] Of course, those skilled in the art can select the number of culture racks 4 and the number of aquaculture tanks 1 on the culture rack 4 according to their actual needs.
[0061] In a specific embodiment, a realizable structure of the sedimentation tank 2 is further provided. The sedimentation tank 2 is a vertical flow sedimentation tank 2. The top of the vertical flow sedimentation tank 2 is provided with a water outlet for the supernatant to flow out, and the water outlet is communicated with a water outlet pipeline. The vertical flow sedimentation tank 2 is provided with a water inlet, and the water inlet is communicated with the water outlet pipeline of the aquaculture tank 1. In actual application, the wastewater discharged from the aquaculture tank 1 flows into the vertical flow sedimentation tank 2, and the large particle metabolic wastes in the wastewater are separated by their own gravity and begin to precipitate and accumulate downward, forming supernatant and sediment.
[0062] Further, in order to achieve the purpose of timed sewage discharge of the vertical flow sedimentation tank 2, a sewage outlet is provided at the bottom of the vertical flow sedimentation tank 2, and a timed solenoid valve 8 is communicated in the sewage outlet. The timed solenoid valve 8 is used to control the timed sewage discharge of the sewage outlet. In actual application, the user can set the periodic sewage discharge time of the timed solenoid valve 8 according to the sewage discharge cycle. The timed solenoid valve 8 is switched on and off at preset time intervals, so that the dirt in the vertical flow sedimentation tank 2 can be discharged from the vertical flow sedimentation tank 2 regularly.
[0063] In a specific implementation manner, a realizable structure of the purification component 3 is further provided. The purification component 3 includes an ultraviolet sterilization device 30, a protein separation and ozone generator 32, forming a schematic diagram of the purification component 3 as Figures 1 to 4 shown.
[0064] A feasible structure of the ultraviolet sterilization device 30 is further provided. The ultraviolet sterilization device 30 preferably adopts a flow-through ultraviolet sterilization device 30. The water inlet of the ultraviolet sterilization device 30 is communicated with the water outlet pipeline of the sedimentation tank 2, and the water outlet of the ultraviolet sterilization device 30 is communicated with the water inlet pipeline of the protein separator 31. In actual application, the water flowing out of the sedimentation tank 2 is sterilized and disinfected once by the flow-through ultraviolet sterilization device 30.
[0065] A feasible structure of the protein separator 31 is further provided. The water inlet of the protein separator 31 is communicated with the water outlet pipeline of the ultraviolet sterilization device 30, and the water outlet of the protein separator 31 is communicated with the water inlet pipeline of the culture tank 1. In actual application, the water after sterilization and disinfection flows into the protein separator 31 for organic matter separation.
[0066] A feasible structure of the ozone generator 32 is further provided. The ozone generator 32 is communicated with the protein separator 31, and a jet ejector is communicated between the ozone generator 32 and the protein separator 31 through a silica gel hose. The jet ejector is used to inject the ozone generated by the ozone generator 32 into the protein separator 31. In actual application, the ozone generator 32 generates ozone, and the ozone is injected into the protein separator 31 by the jet ejector, so that the water and ozone are fully mixed in the protein separator 31 to achieve the purpose of secondary sterilization.
[0067] As can be seen from the above, when the purification assembly 3 is actually applied, the water flowing out of the sedimentation tank 2 is sterilized and disinfected once by the flow-through ultraviolet sterilization device 30. Then, the water after sterilization and disinfection flows into the protein separator 31 for organic matter separation. At the same time, the ozone generator 32 generates ozone, so that the water and ozone are fully mixed in the protein separator 31 to achieve the purpose of secondary sterilization, better realizing the aseptic water circulation, being beneficial to improving the quality of nereis, and ensuring the stability and high quality of the bait for the parent shrimp end.
[0068] Further, in order to achieve the purpose of secondary water regulation, the nereis temporary culture and purification device further includes a sump 5 and a chiller 6. A sump 5 is communicated between the ultraviolet sterilization device 30 and the sedimentation tank 2, and a chiller 6 is communicated between the ultraviolet sterilization device 30 and the sump 5. In actual application, the supernatant of the sedimentation tank 2 flows into the sump 5 for secondary sedimentation and water redistribution. The supernatant of the sump 5 flows into the chiller 6 for temperature control to keep the water temperature within the temperature required for nereis culture. Finally, the water after temperature adjustment flows into the purification assembly 3 for purification.
[0069] A water pump 7 is communicated on the pipeline between the sump 5 and the chiller 6. The whole system can complete the water body circulation through this water pump 7. Of course, the water pump 7 can also be arranged on the water outlet pipeline of the purification assembly 3, and other feasible positions can also be selected by those skilled in the art.
[0070] A return water valve is also provided between the collecting tank 5 and the chiller 6. A three-way pipe is connected to the outlet pipeline of the collecting tank 5. One end of the three-way pipe is connected to the collecting tank 5, one end is connected to the chiller 6, and the other end is connected to the return water valve. The pipeline connected to the return water valve is connected back to the collecting tank 5 to adjust the water flow rate of the entire system.
[0071] It should be noted that the materials used for the above-mentioned inlet pipeline and outlet pipeline are preferably PVC pipes (Polyvinyl chloride), and of course, other pipeline body materials commonly used in the aquaculture industry can be selected by those skilled in the art.
[0072] As can be seen from the above text, the basic structure and principle of this solution are known. The following will be described in combination with actual application scenarios.
[0073] Before temporary cultivation, first clean the entire system with fresh water, and then add seawater to make the seawater circulate through the entire system to simulate the survival of Nephtys bidentata.
[0074] Subsequently, turn on the water pump 7. After the water body can complete the circulation, adjust the inlet and outlet valves of each device and the temporary cultivation tank. After the water level is stable, put Nephtys bidentata (3.5 - 7.0 kg per square meter), turn on the exhaust and ventilation system, close the access passage for personnel in the temporary cultivation system, evacuate personnel from the workshop, and sequentially turn on the timing solenoid valve 8, chiller, in-line ultraviolet disinfection device, and ozone generator 32 in the central control box; during temporary cultivation, the water temperature will slowly drop from room temperature to 15 °C and be maintained until the end of temporary cultivation, and the ozone concentration in the water body is controlled below 0.05 mg / L; after maintaining purification for 20 hours, turn off the ozone machine. After the exhaust and ventilation system discharges the ozone residue in the workshop, turn off the chiller and in-line ultraviolet disinfection device, then open the personnel passage, take out the worms and pack them for sale.
[0075] After the temporary cultivation is over, open the sewage valve of the protein separator 31 and the sewage valve of the vertical flow sedimentation tank 2. After discharging the metabolic waste, close them. Then turn on the ozone machine and ultraviolet, close the personnel passage, increase the ozone concentration, and use the ozone in the system itself to disinfect the system to prepare for the next batch of worm temporary cultivation.
