Description

Technical Field

[0001] This utility model relates to the field of rotifer farming equipment technology, and in particular to an integrated device for circulating water culture of rotifers. Background Technology

[0002] Rotifers are microscopic organisms that are often used in laboratory research, feed cultivation, and other fields. In particular, in aquaculture, rotifers serve as a high-quality natural feed for aquatic animals such as fish and shrimp, and play a significant role in the growth of seedlings.

[0003] Recirculating aquaculture of rotifers is an advanced farming method. The recirculating aqua system, through filtration, disinfection, and water quality regulation, can ensure stable water quality for rotifer growth and reduce the impact of water quality fluctuations on rotifer growth. However, existing rotifer farming processes do not buffer the flow rate of the recirculating water entering the culture tank. Excessive water flow makes it difficult for rotifers to remain stably suspended in the water, affecting their feeding and growth. At the same time, excessive water flow can also scatter rotifer eggs and larvae, reducing their hatching and survival rates, thereby affecting the rotifer reproduction rate. Utility Model Content

[0004] This invention provides an integrated device for culturing rotifers in circulating water, aiming to solve the problem in the prior art where the growth and reproduction of rotifers are affected by excessive circulating water flow.

[0005] This utility model provides an integrated device for culturing rotifers in recirculating water, including a culture tank and a purification tank that are circulated and connected by pipes;

[0006] The water inlet pipe of the breeding box includes a main water inlet pipe and multiple branch water inlet pipes connected to the breeding box. The main water inlet pipe and the multiple branch water inlet pipes are connected, and the outlets of the multiple branch water inlet pipes are aligned with the interior of the breeding box.

[0007] At least one slow-flow filter plate is installed below the outlet of the water inlet branch pipe. The slow-flow filter plate is connected to the breeding tank and is located above the water surface in the breeding tank. The slow-flow filter plate is used to slow down the inlet water flow rate so that the water forms a drip when it flows out.

[0008] In one embodiment, at least one outlet is provided on the wall of the inlet branch pipe;

[0009] The integrated device further includes a speed regulating mechanism, which includes an arc-shaped baffle, an adjusting gear, and an adjusting motor. The arc-shaped baffle is slidably installed inside the water inlet branch pipe, and the water outlet is provided on the sliding trajectory of the arc-shaped baffle. The arc-shaped baffle is meshed with the adjusting gear, and the adjusting gear is driven by the adjusting motor. The transmission of the adjusting gear is used to drive the arc-shaped baffle to slide circumferentially inside the water inlet branch pipe to adjust the size of the water outlet.

[0010] In one embodiment, the regulating motor is fixed to the end of the water inlet branch pipe away from the main water inlet pipe, and the regulating gear is fixed on the output shaft of the regulating motor. The regulating gear is arranged coaxially with the water inlet branch pipe.

[0011] The inner arc surface of the arc-shaped baffle is provided with multiple sets of teeth for meshing with the adjusting gear, and the teeth are arranged adjacent to the adjusting gear.

[0012] In one embodiment, multiple slow-flow filter plates are fixed to the aquaculture box, and the multiple slow-flow filter plates are arranged vertically between each other.

[0013] In one embodiment, the slow-flow filter plate is a cotton board.

[0014] In one embodiment, the purification chamber is provided with a partition that divides the purification chamber into a protein separation chamber and an ammonia nitrogen removal chamber;

[0015] A bubble generator is fixedly installed at the bottom of the protein separation chamber, and the bubble generator is used to generate bubbles in the protein separation chamber.

[0016] A base material container is hung on the ammonia nitrogen removal chamber, and the base material container is filled with ammonia nitrogen removal base material.

[0017] In one embodiment, a collection trough is fixed to the outer wall of the purification box;

[0018] At least one linear motion mechanism is fixed to the top of the purification box. The moving part of the linear motion mechanism is fixed with a defoaming pusher plate. The movement of the defoaming pusher plate is used to push the air bubbles on the purification box into the collection tank.

[0019] In one embodiment, the integrated device further includes a water replenishment mechanism;

[0020] The water replenishment mechanism includes a water level monitor and a water replenishment component. The water level monitor is located inside the breeding tank, and the water outlet of the water replenishment component is located above the slow-flow filter plate.

[0021] In one embodiment, the integrated device further includes a water temperature regulating mechanism;

[0022] The water temperature regulation mechanism includes a controller, a heating element, and a water temperature monitor, both of which are located inside the breeding tank. The controller is signal-connected to the heating element and the water temperature monitor, and is used to control the heat output of the heating element based on the monitoring data from the water temperature monitor.

[0023] In one embodiment, the water temperature regulation further includes a cooling fan directed at the main water inlet pipe, and the cooling fan is signal-connected to the controller.

[0024] As can be seen from the above technical solutions, this utility model has the following advantages:

[0025] This embodiment provides an integrated device for circulating water culture of rotifers. Since the main water inlet pipe is connected to multiple branch water inlets, the branch water inlets divert the water in the main water inlet pipe, reducing the impact force of the water flow. Furthermore, since the water flowing out of the branch water inlets falls onto the slow-flow filter plate, the water flow stays and filters within the slow-flow filter plate, forming a drip curtain after the circulating water passes through the slow-flow filter plate. This not only increases the surface area and time of contact between the water and air, improving the oxygen content of the water and promoting the growth of rotifers, but also slows down the flow rate of the circulating water entering the culture tank, preventing excessive water flow from affecting the growth and reproduction of rotifers, thus improving the efficiency of the culture.

Detailed Implementation

[0035] This utility model provides an integrated device for culturing rotifers in circulating water, which solves the technical problem in the prior art where the growth and reproduction of rotifers are affected by excessive circulating water flow.

[0036] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0037] Please see Figures 1 to 6 The present invention provides an integrated device for culturing rotifers in recirculating water, comprising a culture tank 1 and a purification tank 2 that are connected by a pipeline;

[0038] The water inlet pipe 10 of the breeding box 1 includes a main water inlet pipe 100 connected to the breeding box 1 and multiple water inlet branch pipes 101. The main water inlet pipe 100 and multiple water inlet branch pipes 101 are connected, and the outlets 1010 of the multiple water inlet branch pipes 101 are aligned with the interior of the breeding box 1.

[0039] At least one slow-flow filter plate 3 is installed below the outlet 1010 of the inlet branch pipe 101. The slow-flow filter plate 3 is connected to the breeding tank 1 and is located above the water surface of the breeding tank 1. The slow-flow filter plate 3 is used to slow down the inlet flow rate so that the water forms a drip when it flows out.

[0040] The inlet end of the inlet pipe 10 is connected to a first pump body 12, which is used to pump water from the purification tank 2 into the breeding tank 1 through the inlet pipe 10. The outlet pipe 11 of the breeding tank 1 is connected to the purification tank 2, and the outlet pipe 11 of the breeding tank 1 is connected to a second pump body 13, which is used to pump water from the breeding tank 1 into the purification tank 2 through the outlet pipe 11. The first pump body 12 and the second pump body 13 are both installed inside the purification tank 2. The water circulation in the breeding tank 1 and the purification tank 2 is realized through the cooperation of the first pump body 12, the second pump body 13 and each pipe.

[0041] In the operation of this embodiment, water in the purification tank 2 enters the breeding tank 1 through the inlet pipe 10. The water flows from the main inlet pipe 100 into multiple inlet branch pipes 101, and then flows out from the multiple inlet branch pipes 101 onto the slow-flow filter plate 3. The water stays on the slow-flow filter plate 3 for filtration, and under the action of the dense pores of the slow-flow filter plate 3, the water flows out and forms a dripping water curtain that falls into the breeding tank 1. The excrement produced by the rotifers' metabolism and the remaining feed residue in the breeding tank 1 are recycled back to the purification tank 2. The equipment in the purification tank 2 is used to purify the organic matter and suspended solids in the water, thereby completing the water cycle.

[0042] As can be seen from the above, the water is first diverted through the inlet branch pipe 101. The diversion effect can effectively reduce the impact force of the water flow. In addition, the slow-flow filter plate 3 forms a dripping water curtain with a slower flow rate. The combination of the diversion by the inlet branch pipe 101 and the dripping water curtain of the slow-flow filter plate 3 greatly slows down the flow rate of the circulating water into the breeding tank 1, avoiding the impact of excessive water flow on the growth and reproduction of rotifers, which is conducive to improving breeding efficiency.

[0043] Compared with existing technologies, the advantages of this embodiment are as follows: First, existing rotifer farming processes do not buffer the flow rate of circulating water entering the farming tank 1. Excessive water flow makes it difficult for rotifers to remain stably suspended in the water, affecting their feeding and growth. In this embodiment, the dripping of the slow-flow filter plate 3 effectively controls the water flow rate entering the farming tank 1, effectively solving the problem of rotifer growth and reproduction being affected by excessive circulating water flow. Second, the slow-flow filter plate 3 can filter bacterial films and bacteria in the circulating water, playing a secondary filtration role outside of the purification tank 2, making the water entering the farming tank 1 cleaner.

[0044] In one specific embodiment, such as Figures 1 to 3As shown, a feasible arrangement structure for the slow-flow filter plates 3 is further provided. Multiple slow-flow filter plates 3 are fixed to the breeding box 1. The multiple slow-flow filter plates 3 are arranged vertically between each other, and sufficient gap space is left between adjacent slow-flow filter plates 3. That is, when water flows out from the inlet branch pipe 101, it will pass through the upper slow-flow filter plate 3 and the lower slow-flow filter plate 3 in sequence. Drips will be formed under the multiple layers of slow-flow filter plates 3. Therefore, the more slow-flow filter plates 3 there are, the more layers of drip curtains will be formed, which will further slow down the water flow speed. As for the number of slow-flow filter plates 3, it can be two layers, three layers, or other reasonable numbers. This application does not impose too many restrictions on this.

[0045] In this embodiment, the slow-flow filter plate 3 includes a mounting frame and a filter plate body. The filter plate body is fixed inside the mounting frame, and the mounting frame is fixedly connected to the inner wall of the breeding box 1, thereby realizing the connection between the slow-flow filter plate 3 and the breeding box 1.

[0046] Based on the above embodiments, such as Figure 3 As shown, the slow-flow filter plate 3 is a rattan cotton board. The rattan cotton board has the special characteristics of high-density pores and fine spiral structure, which has good permeability, good durability, good deformation resistance and long service life. It can not only make the circulating water form a drip curtain in the gaps of the rattan cotton board, increasing the surface area and time of contact between the water and the air, and increasing the oxygen content of the water, which is conducive to the growth of rotifers, but also the rattan cotton board can filter the bacterial film and bacteria and insects in the circulating water, making the water entering the breeding tank 1 cleaner.

[0047] It should be noted that the slow-flow filter plate 3 can also be a porous structure plate or a ceramic filter plate. However, although the porous structure plate can also perform the function of filtration, its durability and resistance to deformation are poor. As for the ceramic filter plate, the pores of the ceramic filter plate are prone to scaling and clogging. Those skilled in the art can choose according to actual needs.

[0048] In one specific embodiment, such as Figure 3 and Figure 4As shown, in order to control the rate of circulating water flow, at least one outlet 1010 is provided on the wall of the inlet branch pipe 101. The integrated device also includes a speed regulating mechanism 4, which includes an arc-shaped baffle 40, an adjusting gear 41, and an adjusting motor 42. The arc-shaped baffle 40 is slidably installed inside the inlet branch pipe 101, and the outlet 1010 is provided on the sliding trajectory of the arc-shaped baffle 40. The arc-shaped baffle 40 is meshed with the adjusting gear 41, and the adjusting gear 41 is driven by the adjusting motor 42. The drive of the adjusting gear 41 is used to drive the arc-shaped baffle 40 in the inlet branch pipe 101. The size of the outlet 1010 is adjusted by circumferential sliding within the pipe 101. Circumferential sliding refers to the sliding of the arc-shaped baffle 40 in the circumferential direction of the inner wall of the inlet branch pipe 101. In practice, when it is necessary to adjust the water flow rate at the outlet 1010 of the inlet branch pipe 101, the adjusting motor 42 can be started and the adjusting gear 41 can be rotated to make the arc-shaped baffle 40 slide circumferentially within the inlet branch pipe 101. This allows the arc-shaped baffle 40 to move closer to or further away from the outlet 1010, thereby adjusting the area of ​​the outlet 1010 and controlling the rate of the circulating water droplets, effectively improving the practicality of the device.

[0049] In this embodiment, in order to further slow down the water flow rate, the outlet 1010 is evenly arranged on the pipe wall of the inlet branch pipe 101, and the outlet 1010 forms a drip hole structure. In specific implementation, the water flowing out from the drip hole will fall into the slow flow filter plate 3 in the form of drips, which further limits the water flow rate.

[0050] In this embodiment, as Figure 3 and Figure 4 As shown, a feasible arrangement structure for the speed regulating mechanism 4 is further provided. An regulating motor 42 is fixed at one end of the water inlet branch pipe 101 away from the main water inlet pipe 100. An regulating gear 41 is fixed on the output shaft of the regulating motor 42. The regulating gear 41 is arranged coaxially with the water inlet branch pipe 101. Multiple sets of teeth 400 for meshing with the regulating gear 41 are provided on the inner arc surface of the arc-shaped baffle 40. The teeth 400 are arranged adjacent to the regulating gear 41. That is, multiple teeth 400 form an arc-shaped arrangement structure along the edge of the arc-shaped baffle 40. In specific implementation, the regulating motor 42 can drive the regulating gear 41 to rotate, thereby driving the teeth 400 to mesh and move, thereby driving the arc-shaped baffle 40 to slide in the circumferential direction of the inner wall of the water inlet branch pipe 101.

[0051] In one specific embodiment, such as Figure 5As shown, to improve the purification effect, a feasible arrangement structure for the purification chamber 2 is further provided. The purification chamber 2 is equipped with a partition 25, which divides the purification chamber 2 into an interconnected protein separation chamber 20 and an ammonia nitrogen removal chamber 21. Along the water flow direction of the purification chamber 2, the protein separation chamber 20 and the ammonia nitrogen removal chamber 21 are arranged sequentially, that is, the protein separation chamber 20 is closer to the water inlet of the purification chamber 2. A bubble generator 200 is fixedly installed at the bottom of the protein separation chamber 20, and the bubble generator 200 is used to generate bubbles within the protein separation chamber 20. A substrate container 210 is hung on the ammonia nitrogen removal chamber 21. The chamber 10 is filled with ammonia nitrogen removal substrate. In practice, the water entering the purification tank 2 first enters the protein separation chamber 20. In the protein separation chamber 20, the bubble generator 200 generates a large number of bubbles. As these bubbles rise, they adsorb fine suspended solids and organic matter in the water, forming foam and overflowing from the top of the protein separation chamber 20, effectively separating the solids and liquids in the circulating water and purifying the circulating water quality. Subsequently, the water enters the ammonia nitrogen removal chamber 21. In the ammonia nitrogen removal chamber 21, the ammonia nitrogen in the water is converted into non-toxic salts by the ammonia nitrogen removal substrate, providing a healthy and stable water quality environment for the growth and reproduction of rotifers.

[0052] It should be noted that rotifers produce a large amount of ammonia nitrogen during metabolism. This ammonia nitrogen is toxic and can affect the vitality of rotifers. Therefore, the ammonia nitrogen removal chamber 21 mentioned above is needed to remove it.

[0053] In this embodiment, the bubble generator 200 is a microbubble generator 200. The microbubble generator 200 can generate a large number of tiny bubbles. These tiny bubbles can further increase the ability to adsorb fine suspended matter and organic matter, making the separation of proteins in the water more thorough.

[0054] In this embodiment, the substrate container 210 includes a container support, a perforated container plate, and a filter rod containing ammonia nitrogen removal substrate. The container plate is hooked to the inner wall of the purification tank 2 by the container support, and the filter rod is installed in the holes on the container plate, thereby realizing substrate containment. This allows the ammonia nitrogen removal substrate to convert ammonia nitrogen in the water into non-toxic salts. The ammonia nitrogen removal substrate is nitrifying bacteria. Through the nitrification of the nitrifying bacteria, these ammonia nitrogen substances are converted into non-toxic nitrates, providing a healthy and stable water quality environment for the growth and reproduction of rotifers.

[0055] It should be noted that the tiny bubbles generated by the microbubble generator 200 adsorb organic matter and suspended matter, forming foam that floats on the water surface. In one embodiment, in order to remove debris from the water surface of the purification tank 2, a collection tank 22 is fixed to the outer wall of the purification tank 2, and at least one linear motion mechanism 23 is fixed to the top of the purification tank 2. The moving part of the linear motion mechanism 23 is fixed with a defoaming pusher 24. The movement of the defoaming pusher 24 is used to push the bubbles on the purification tank 2 into the collection tank 22. In specific implementation, the linear motion mechanism 23 will drive the defoaming pusher 24 to move back and forth, pushing the bubbles or foam floating on the water surface of the purification tank 2 into the collection tank 22 for collection. The collection tank 22 can prevent foam from overflowing and contaminating the purification tank 2, and remove the foam containing organic matter and suspended matter generated by the protein separation chamber 20.

[0056] In this embodiment, as Figure 5 As shown, the collection tank 22 is arranged around the outer wall of the protein separation chamber 20 of the purification box 2. There are two linear movement mechanisms 23, and the linear movement mechanism 23 is an electric push rod. The two electric push rods are respectively arranged on the top of the wall of the ammonia nitrogen removal chamber 21 of the purification box 2. The piston rods of the two electric push rods face the protein separation chamber 20. The same defoaming push plate 24 is connected to both electric push rods. The defoaming push plate 24 is mounted on the top of the purification box 2. In specific implementation, the piston rod of the electric push rod can drive the defoaming push plate 24 to move, thereby pushing the foam on the water surface into the collection tank 22.

[0057] It should be noted that the water in breeding tank 1 and purification tank 2 will decrease due to evaporation, causing the salinity of the circulating water to rise. Excessive salinity will inhibit the growth and reproduction of rotifers, and may even lead to their death. After the water in breeding tank 1 decreases due to evaporation, the water level in breeding tank 1 will drop. Figure 2 As shown, in order to replenish water to the breeding tank 1 normally, the integrated device also includes a water replenishment mechanism 5; the water replenishment mechanism 5 includes a water level monitor 50 and a water replenishment component 51. The water level monitor 50 is located inside the breeding tank 1, and the water outlet of the water replenishment component 51 is located above the slow-flow filter plate 3. In specific implementation, the water level monitor 50 detects the water level in the breeding tank 1. When the water level is low, the water replenishment component 51 replenishes water to the breeding tank 1 to avoid excessive salinity of the water due to water evaporation, which would affect the growth of rotifers.

[0058] In this embodiment, the water supply component 51 includes a water supply pipe and an electromagnetic valve for controlling the water flow in the water supply pipe. The outlet end of the water supply pipe is located above the slow-flow filter plate 3. The electromagnetic valve is electrically connected to the water level monitor 50. In specific implementation, after the water level monitor 50 detects the water level, it transmits an electrical signal to the electromagnetic valve. The electromagnetic valve opens, and the external water in the water supply pipe flows into the breeding tank 1, so that the salinity of the water in the breeding tank 1 is maintained within a suitable range. The outlet end of the water supply pipe is located on the rattan board. The rattan board can buffer the water flow from the water supply pipe to prevent the water flow from being too large, which would affect the growth and reproduction of rotifers. The water level monitor 50 is a WH311 Dongfang Wanhe water level monitor 50.

[0059] It should be noted that although rotifers are relatively adaptable to water temperature, the optimal water temperature for their growth is 24℃-30℃. When the water temperature is too low, the low temperature will reduce the metabolic activity of rotifers, affecting their feeding, digestion, and absorption abilities. Figure 2 As shown, in order to ensure the normal temperature of the breeding tank 1, the integrated device also includes a water temperature regulation mechanism 6; the water temperature regulation mechanism 6 includes a controller 62, a temperature regulation component 60, and a water temperature monitor 61. The controller 62 is connected to the temperature regulation component 60 and the water temperature monitor 61 by signal. The water temperature monitor 61 is installed inside the breeding tank 1. The controller 62 is used to control the temperature regulation component 60 to regulate the water temperature according to the monitoring data of the water temperature monitor 61. In specific implementation, when the water temperature monitor 61 detects that the water temperature is too low or too high, it will send an electrical signal to the controller 62. The controller 62 sends a signal to make the temperature regulation component 60 work to keep the water at a suitable temperature, avoid the water temperature being too high or too low, and promote the growth of rotifers.

[0060] In this embodiment, as Figure 2 and Figure 6 As shown, the temperature regulation component 60 includes a heating wire 600 and a cooling fan 601. The heating wire 600 is installed inside the breeding tank 1, and the cooling fan 601 is directed towards the water inlet pipe 100. In practice, when the water temperature monitor 61 detects that the water temperature is too low, it sends an electrical signal to the controller 62. The controller 62 then sends a signal to activate the heating wire 600, which heats the water. Conversely, when the water temperature monitor 61 detects that the water temperature is too high, it sends an electrical signal to the controller 62. The controller 62 then sends a signal to activate the cooling fan 601, which blows air to reduce the surface temperature of the water inlet pipe 100, thereby cooling the water flowing through it. The cooled water then enters the breeding tank 1, thus lowering the circulating water temperature and maintaining it at a suitable temperature.

[0061] In this embodiment, the water temperature monitor 61 is a BN-SW Born water temperature meter, and the controller 62 is a programmable PLC controller 62.

[0062] Based on the above embodiments, in one embodiment, in order to improve the heat dissipation effect, the main water inlet pipe 100 includes a first connecting pipe section 1000, a serpentine connecting pipe section 1001, and a second connecting pipe section 1002 connected in sequence. The first connecting pipe section 1000 is connected to the purification tank 2, and a first pump body 12 for pumping water from the purification tank 2 into the breeding tank 1 is connected to the water inlet end of the first connecting pipe section 1000. The serpentine connecting pipe section 1001 is located within the working range of the cooling fan 601. The serpentine connecting pipe section 1001 can increase the water flow trajectory, thereby better heat dissipation. The second connecting pipe section 1002 is connected to the water inlet branch pipe 101.

[0063] With the above settings, the water temperature monitor 61, together with the controller 62, heating resistance wire, serpentine tube and cooling fan 601, controls the water temperature for rotifer cultivation. The water level monitor 50, together with the water supply pipe, controls the salinity of the water for rotifer cultivation, so that the water is kept at a suitable temperature and salinity for rotifer growth, which is conducive to increasing rotifer farming yield and improving the practicality of the device.

[0064] As described above, the overall structure of this application is as follows: Rotifers are placed in a rearing tank 1 for cultivation. A second pump 13, through an outlet pipe 11, discharges the excrement from the rotifers' metabolism, residual feed, and water from the rearing tank 1 into a purification tank 2. In the rearing tank 1, a bubble generator 200 produces a large number of fine bubbles. As these bubbles rise, they adsorb fine suspended solids and organic matter in the water, forming foam that is pushed into a collection tank 22 by a defoaming pusher 24 for collection. Subsequently, the water is nitrified by nitrifying bacteria in the ammonia nitrogen removal substrate, reducing... The ammonia nitrogen produced by rotifer metabolism in the water is converted into non-toxic nitrates, thereby purifying the circulating water. The purified water is pumped into the main inlet pipe 100 through the first pump body 12. The inlet branch pipe 101 diverts the water in the main inlet pipe 100 to reduce the impact force of the water flow. The water in the main inlet pipe 100 forms a drip curtain through the drip holes of the outlet 1010 and falls onto the two layers of rattan cotton board below. The circulating water forms a drip curtain in the gaps of the rattan cotton board, which slows down the flow rate of the circulating water entering the breeding tank 1 and avoids the water flow being too large, which will affect the growth and reproduction of rotifers and help improve the breeding efficiency.
