Technical Field

[0001] The present application relates to the technical field of aquaculture warehouse oxygenation, and in particular to an aquaculture warehouse oxygenation system with automatic adjustment. Background Art

[0002] The "breeding chamber" in aquatic oxygen cone refers to a closed or semi-closed structure used for oxygen cone aquatic organisms. These breeding chambers are usually designed to accumulate a certain amount of oxygen cone water and provide a relatively stable living environment for oxygen cone organisms.

[0003] The oxygenation system in the breeding tank is very important for maintaining appropriate dissolved oxygen levels, ensuring the healthy growth of aquatic organisms and improving the efficiency of oxygen cones. By using the oxygenation system, it can ensure that the oxygen cone organisms grow in a stable and healthy environment, thereby improving the success rate and economic benefits of the oxygen cone.

[0004] Traditional oxygenation systems are not convenient for accurately adjusting the ratio of oxygen and seawater according to the actual needs of oxygen cone organisms, which can easily lead to too high or too low dissolved oxygen levels. Too high dissolved oxygen levels may lead to oxygen waste, while too low dissolved oxygen levels will affect the growth and health of oxygen cone organisms. At the same time, if the oxygen supply is not adjusted according to actual conditions, it may lead to unnecessary oxygen supply and increase energy consumption. Secondly, the main equipment of the oxygenation system may malfunction after long-term use, which will cause unstable supply of seawater or oxygen, thereby affecting the efficiency of dissolved oxygen. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems in the prior art that the traditional oxygen enrichment system is not convenient for automatically and accurately adjusting the ratio of oxygen and seawater according to the actual needs of oxygen cone organisms, which easily leads to too high or too low dissolved oxygen levels. Too high dissolved oxygen levels may lead to oxygen waste, while too low dissolved oxygen levels may affect the growth and health of oxygen cone organisms. To this end, the present application proposes an aquaculture tank oxygen enrichment system with automatic adjustment.

[0006] According to an embodiment of the present application, an oxygen enrichment system for a breeding warehouse with automatic adjustment includes a breeding warehouse main body, a water quality sensor, a transformer and a PLC controller. A water quality sensor is installed inside the breeding warehouse main body. When the dissolved oxygen level inside the breeding warehouse main body detected by the water quality sensor is lower than the set value, a signal is sent to the PLC controller. The PLC controller controls the adjustable oxygen enrichment system to increase the oxygen supply. The adjustable oxygen enrichment system is provided with two groups located on both sides of the breeding warehouse main body.

[0007] Furthermore, the adjustable oxygenation system includes a pipeline installed on the side wall of the breeding warehouse body, and an inlet valve, an oxygen cone pump, a check valve, a flow valve, an oxygen cone, a stop valve and an outlet valve are installed on the pipeline in sequence.

[0009] Furthermore, a safety valve is installed at the upper end of the oxygen cone.

[0010] Furthermore, a liquid level meter and a liquid level sensor are installed at a position close to the lower side of the oxygen cone.

[0011] Furthermore, an oxygen supply pipeline is installed at the oxygen inlet of the oxygen cone, and the oxygen inlet of the oxygen supply pipeline is connected to the oxygen outlet of the oxygen generator.

[0012] Furthermore, a flow regulating valve, a flow meter, a ball valve, and a check valve are sequentially installed on the oxygen delivery pipeline.

[0013] Furthermore, a pressure sensor is installed at the connection portion between the oxygen concentrator and the oxygen supply pipeline.

[0014] Furthermore, filter 1 and filter 2 are installed at positions corresponding to inlet valve 1 and inlet valve 2 inside the breeding warehouse body, respectively.

[0015] 1. The beneficial effects of the present application are as follows: the dissolved oxygen level in the main body of the breeding warehouse is continuously monitored by a water quality sensor. When the dissolved oxygen level is detected to be lower than a set value, the seawater in the main body of the breeding warehouse is pumped into the oxygen cone 1 through the oxygen cone pump 1. The water quality sensor sends a signal to the PLC controller, and the PLC controller controls the flow regulating valve to open to increase the oxygen supply. The flow meter records the inflow of oxygen to ensure that an appropriate amount of oxygen is added to the main body of the breeding warehouse, and by adjusting the water volume of the oxygen cone pump 1 and the opening of the flow valve 1 after the pump, more seawater is allowed to enter to prevent the liquid level in the oxygen cone from dropping due to excessive oxygen, thereby maintaining the dissolved oxygen efficiency; and when the current set of adjustable oxygenation systems cannot meet the demand, the other set is turned on and used in combination to balance the dissolved oxygen level in the breeding warehouse.

[0016] 2. The beneficial effect of the present application is: installing a pressure sensor on the oxygen delivery pipeline to monitor the pressure of the oxygen supply in real time, prevent insufficient oxygen supply, and ensure the continuity of dissolved oxygen operation.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] A breeding warehouse oxygenation system with automatic adjustment according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] like Figure 1-Figure 6 As shown, according to an embodiment of the present application, an aeration system for a breeding warehouse with automatic adjustment includes a breeding warehouse main body 1, a water quality sensor 24, a transformer 28 and a PLC controller 27. A water quality sensor 24 is installed inside the breeding warehouse main body 1. The water quality sensor 24 is installed in the middle position of the breeding warehouse main body 1 as much as possible, so as to better reflect the average water quality of the entire breeding warehouse main body 1.

[0035] When the dissolved oxygen level inside the breeding warehouse body 1 detected by the water quality sensor 24 is lower than the set value, a signal is sent to the PLC controller 27, and the PLC controller 27 controls the adjustable oxygenation system to increase the oxygen supply. The adjustable oxygenation system has two groups located on both sides of the breeding warehouse body 1.

[0036] Priority is given to using one set of adjustable oxygenation systems for dissolved oxygen. When the current set of adjustable oxygenation systems cannot meet the demand, another set is turned on. The two sets are used in coordination to balance the dissolved oxygen level in the breeding chamber. Even if one system needs maintenance or repair, the other system can take over seamlessly to reduce downtime and avoid negative impacts on oxygen cone organisms. In addition, the two systems can be flexibly adjusted according to the needs of oxygen cone organisms at different growth stages to ensure that the dissolved oxygen level always remains within the optimal range.

[0037] Among them, the adjustable oxygenation system includes a water outlet pipe installed at the water outlet of the breeding warehouse body 1, and the water outlet pipe is sequentially installed with an inlet valve 2, an oxygen cone pump 3, a check valve 4 and a flow valve 5. When extracting seawater, the PLC controller 27 controls the operation of the oxygen cone pump 3 and opens the inlet valve 2 at the same time, and the seawater is pumped into the oxygen cone 6 through the oxygen cone pump 3.

[0038] A liquid level meter 21 and a liquid level sensor 22 are installed near the lower side of the oxygen cone 6. The liquid level meter 21 can intuitively display the current height of the seawater in the oxygen cone 6, so that the operator can grasp the liquid level in the oxygen cone 6 at any time. The liquid level sensor 22 can monitor the liquid level in real time and send the data to the PLC controller 27, which can realize automatic control. When the liquid level is too low, water is automatically replenished. When it is too high, water supply is stopped or excess water is discharged. Through automatic control, the need for manual intervention is reduced and the overall operation efficiency of the system is improved.

[0039] Since a filter 23 is installed at a position corresponding to the inlet valve 2 inside the breeding tank body 1, and a filter 29 is installed at a position corresponding to the inlet valve 9 inside the breeding tank body 1, the seawater is filtered through the filter 23 or the filter 29 when being drawn. The filter 23 uses microorganisms to decompose organic matter, such as ammonia nitrogen and nitrite, and converts them into forms that are less harmful to organisms, such as nitrates, to remove substances in the seawater that may affect the dissolved oxygen level. Filtering the seawater before it leaves the breeding tank body 1 can help reduce the return of harmful substances to the inside of the breeding tank body 1.

[0040] At the same time, the flow regulating valve 16, the check valve 19 and the ball valve 18 on the oxygen supply pipeline are opened, so that the oxygen generated by the oxygen generator 26 enters the oxygen cone 6 through the oxygen supply pipeline, and the oxygen flow rate entering is recorded by the flow meter 17 when the oxygen enters, ensuring that an appropriate amount of oxygen is added to the breeding warehouse body 1, and a pressure sensor 25 is installed at the connection between the oxygen generator 26 and the oxygen supply pipeline. The pressure sensor 25 continuously monitors the pressure of the oxygen delivery pipeline. When the pressure is lower than the set safety threshold, the pressure sensor 25 will send a signal to the PLC controller 27, so that the workers can understand it in time and respond in time to avoid insufficient oxygen supply.

[0041] A safety valve 20 is installed at the upper end of the oxygen cone 6. During the oxygen enrichment process, if the oxygen supply is excessive or the oxygen pressure inside the oxygen cone 6 exceeds the safe range, the system may be damaged. The safety valve 20 can automatically release the excess pressure to prevent the internal pressure of the oxygen cone 6 from being too high.

[0042] The flow rate of oxygen is recorded by the flow meter 17 to ensure that an appropriate amount of oxygen is added to the breeding tank body 1. At the same time, the water volume of the oxygen cone pump 3 and the opening of the flow valve 5 after the pump are adjusted according to the inflow of oxygen to allow more seawater to enter, prevent the liquid level in the oxygen cone 6 from dropping due to excessive oxygen, and maintain the dissolved oxygen efficiency.

[0043] Since the water outlet pipe is connected to the water inlet pipe, after the outlet valve 8 and the stop valve 7 are opened, the dissolved oxygen in the oxygen cone 6 can be injected back into the interior of the breeding warehouse body 1.

[0044] Embodiment 2

[0045] like Figure 1 and Figure 6 As shown, considering that the oxygen cone pump 3 and the flow valve 5 may malfunction after long-term use, in order to ensure the normal use of the adjustable oxygenation system, a second set of pipelines is installed on the other side wall of the breeding warehouse body 1, and an inlet valve 9, an oxygen cone pump 10, a check valve 11, a flow valve 12, an oxygen cone 13, a stop valve 14 and an outlet valve 15 are installed on the pipeline in sequence.

[0046] When the oxygen cone pump 13 runs for the set hours, the PLC controller 27 controls the oxygen cone pump 10 to operate, and at the same time opens the inlet valve 29, and the seawater is pumped into the oxygen cone 13 through the flow valve 212 by the oxygen cone pump 10; at the same time, the PLC controller 27 opens the oxygen valve, and the oxygen enters the oxygen cone 13 and is mixed with the seawater, and the mixed high-dissolved oxygen seawater returns to the aquaculture warehouse main body 1 through the stop valve 214 and the outlet valve 215.

[0047] After the oxygen cone pump 10 and the oxygen cone pump 13 are running stably, the PLC controller 27 stops the oxygen cone pump 3 and closes the inlet valve 2 and the outlet valve 8, and at the same time stops the oxygen supply and closes the flow regulating valve 16.

[0048] The working process of an aquaculture tank oxygenation system with automatic adjustment is as follows: a water quality sensor 24 continuously monitors the dissolved oxygen level in aquaculture tank body 1, and when it is detected that the dissolved oxygen level is lower than a set value, a signal is sent to a PLC controller 27 to control an oxygen cone pump 3 to pump seawater in the aquaculture tank body 1 into an oxygen cone 6. The water quality sensor 24 sends a signal to the PLC controller 27, and the PLC controller 27 controls the flow regulating valve 16 to open, increase the oxygen supply, and record the inflow of oxygen through a flow meter 17 to ensure that an appropriate amount of oxygen is added to the aquaculture tank body 1. Moreover, by adjusting the water volume of the oxygen cone pump 3 and the opening of the flow valve 5 after the pump, more seawater is allowed to enter, so as to prevent the liquid level in the oxygen cone 6 from dropping due to excessive oxygen and maintain the dissolved oxygen efficiency. Furthermore, when the current set of adjustable aeration systems cannot meet the demand, another set is opened and used in combination to balance the dissolved oxygen level in the aquaculture tank.

[0049] The above are only embodiments of the present application and are not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0050] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
