Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a treatment device for tail water in facility-based circulating aquaculture, specifically a sub-controlled nitrification bin. Background Art

[0002] Facility recirculating aquaculture is a method of aquaculture that uses a water circulation system to remove or transform harmful substances such as organic matter, inorganic matter and nitrogen compounds in the aquaculture water, thereby reducing the amount of water replacement, improving water utilization, reducing aquaculture costs, and protecting water resources and the environment. In facility recirculating aquaculture, the treatment of tail water mainly depends on biological nitrification, that is, using nitrifying bacteria to convert ammonia nitrogen and nitrite nitrogen in the water into nitrate nitrogen, thereby reducing the concentration of toxic nitrogen compounds in the water and improving water quality.

[0003] In the prior art, the biological nitrification reaction for treating tail water is generally carried out in a biological nitrification bin. The biological nitrification bin is generally connected to the rear end of the breeding device and is used to treat the tail water in the circulating water breeding system. The traditional biological nitrification bin is an integral structure, which is filled with biological carriers, such as ceramic rings, biological balls, plastic sheets, etc., to increase the attachment area of ​​nitrifying bacteria and improve nitrification efficiency. However, the nitrification bin in the prior art has the following disadvantages: once the nitrification bin is activated, it cannot be stopped. If the nitrification bin is stopped, the tail water in the breeding system cannot be treated in time, thereby affecting the normal breeding of fish and shrimp. As a result, the nitrification bin in the prior art has poor practicality and cannot be maintained or repaired while treating the tail water, resulting in its inability to meet the needs of the circulating water breeding system.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model provides a plurality of nitrification silo bodies. When one of the nitrification silo bodies encounters an emergency such as infection or leakage, the tail water to be treated can be diverted around the faulty nitrification silo body, while the other nitrification silo bodies are kept in normal operation. The nitrification silo body with the problem can be repaired or maintained independently, so that the whole process will not affect the treatment of the tail water in the circulating aquaculture system, thereby improving the stability and maintenance efficiency of the whole system.

[0018] (2) The utility model is provided with an overflow device. When one of the nitrification bin bodies fails, the pipe 3 can be rotated in time to make the water outlet hole and the water outlet channel completely deviate. At this time, the water in the overflow device will not flow out of the water outlet hole, thereby isolating the two nitrification bin bodies. In this way, while the failed nitrification bin body is being repaired, the other nitrification bin bodies can continue to process the tail water in the circulating aquaculture system, thereby not affecting the entire circulating aquaculture system.

[0019] (3) The utility model adjusts the total amount of tail water entering the nitrification bin body by adjusting the relative positions of the water outlet hole and the water outlet channel in the axial direction of the pipe 2, so that each nitrification bin body can maximize the amount of tail water treated while also ensuring the treatment effect of the tail water.

[0020] (4) The utility model can also adjust the amount of tail water entering the nitrification bin body through the water outlet hole per unit time by adjusting the relative position of the water outlet hole and the water outlet channel in the radial direction of the pipe 2, so as to achieve the purpose of adjusting the flow rate of the tail water, ensure that the tail water entering the nitrification bin body can be effectively treated, and improve its treatment efficiency.

[0029] The present invention is further described below in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] In the description of the present utility model, it should be noted that for directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions and positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific protection scope of the present utility model. The terms "first", "second" and the like in the specification and claims of the present utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. The terms "including" and "having" in the specification and claims of the present utility model and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] Reference Figure 1 and Figure 2As shown, an embodiment of the utility model provides a sub-controlled nitrification bin, including a plurality of nitrification bin bodies independently arranged from each other, two adjacent nitrification bin bodies are connected through a connecting pipe 4, the water inlet end of each connecting pipe 4 is connected to one of the nitrification bin bodies, and the water outlet end of each connecting pipe 4 is connected to another nitrification bin body. In this embodiment, by setting a plurality of independent nitrification bin bodies, each nitrification bin body is filled with biological carriers, such as ceramic rings, biological balls, plastic sheets, etc., to increase the attachment area of ​​nitrifying bacteria and improve nitrification efficiency. The traditional nitrification bin is an integral structure, which is generally connected to the rear end of the aquaculture device in the circulating water aquaculture system, and is used to treat the tail water in the fish and shrimp aquaculture process. If the nitrification bin needs to be treated in the prior art, the entire nitrification bin needs to be closed, and if the entire nitrification bin is closed, it will affect the normal aquaculture work of the aquaculture device. In the present application, by providing multiple nitrification silo bodies, when one of the nitrification silo bodies encounters an emergency such as infection or leakage, the tail water that needs to be treated can bypass the faulty nitrification silo body, while maintaining the normal operation of other parts of the nitrification silo bodies, and independently repairing or maintaining the problematic nitrification silo body, so that the whole process will not affect the treatment of the tail water in the circulating aquaculture system, thereby improving the stability and maintenance efficiency of the whole system.

[0032] like Figure 1 and Figure 3 As shown, each nitrification bin body is provided with an overflow device 5, and the overflow device 5 includes a pipe 1 51, a pipe 2 52, and a pipe 3 53. One end of the pipe 1 51 is fixed to the inner wall of the nitrification bin body and connected to the water outlet end of the connecting pipe 4. The connection between the connecting pipe 4 and the pipe 1 51 can be sealed by a sealing ring or other device to improve the stability of the connection between the connecting pipe 4 and the pipe 1 51. The connecting pipes 4 are provided with a pump, and the pump can transport the water in one nitrification bin body to the other nitrification bin body through the connecting pipe 4, thereby effectively treating the tail water in the circulating aquaculture and improving its treatment efficiency.

[0033] Please refer to Figures 5 to 7As shown, the pipe 1 51 and the pipe 2 52 are integrally formed, and the pipe 2 52 is fixed on the side of the pipe 1 51 away from the inner wall of the nitrification warehouse body. The pipe 2 52 is provided with a water outlet channel 521, and the water outlet channel 521 is arranged along the axial direction of the pipe 2 52. The pipe 2 52 includes an outer pipe 2 522 and an inner pipe 2 523. The outer pipe 2 522 and the inner pipe 2 523 are co-centered structures, and the inner diameter of the outer pipe 2 522 is greater than the outer diameter of the inner pipe 2 523. A sliding cavity 524 is formed between the outer pipe 2 522 and the inner pipe 2 523. One end of the pipe 3 53 is inserted into the sliding cavity 524 and slides along the axial direction of the pipe 2 52. The pipe 3 53 is provided with a water outlet hole 531, the aperture of the water outlet hole 531 is less than or equal to the width of the water outlet channel 521, and the water outlet hole 531 is aligned with or deviates from the water outlet channel 521.

[0034] When the water outlet hole 531 is completely aligned with the water outlet channel 521, the amount of tail water in the second pipe 52 flowing into the nitrification bin body through the water outlet hole 531 is the largest. When a portion of the water outlet hole 531 is aligned with the water outlet channel 521, the amount of tail water in the second pipe 52 flowing into the nitrification bin body through the water outlet hole 531 decreases as the overlap between the water outlet hole 531 and the second pipe 52 increases. When the water outlet hole 531 is completely offset from the water outlet channel 521, the water in the connecting pipe 4 will not flow out of the water outlet hole 531, and the overflow device 5 can achieve the purpose of isolating the water flow between the two nitrification bin bodies.

[0035] like Figures 5 to 7As shown, in this embodiment, the length of the slide cavity 524 along the axial direction of the second pipe 52 is much longer than the length of the water outlet channel 521 in the axial direction of the second pipe 52, and in the axial direction of the second pipe 52, the distance between the lowest end of the water outlet channel 521 and the lowest end of the slide cavity 524 is longer than the length of the water outlet channel 521 itself in the axial direction of the second pipe 52. It is ensured that even if the third pipe 53 moves upward to the point where the water outlet hole 531 is flush with the uppermost end of the water outlet channel 521, the section of the third pipe 53 below the water outlet hole 531 will block the water outlet channel 521, so that the water in the second pipe 52 can only flow out along the water outlet hole 531. When the lowest end of the third pipe 53 is inserted into the lowest end of the slide cavity 524, the water outlet hole 531 is flush with the lower end of the water outlet channel 521, that is, at this time, the water outlet position of the overflow device 5 is the lowest. When the water outlet position of the overflow device 5 needs to be adjusted, the pipe 3 53 can be pulled to make the pipe 3 53 slide upward along the sliding cavity 524, so that the water outlet hole 531 will also move upward with the pipe 3 53. When the water outlet hole 531 moves to a suitable position, the pipe 3 53 is stopped from being pulled, so as to adjust the water outlet position of the entire overflow device 5, so as to adjust the depth of the tail water entering the nitrification bin body through the overflow device 5. The whole adjustment process is simple and convenient, and the adjustment effect is good. In addition, by setting the overflow device 5, when one of the nitrification bin bodies fails, the pipe 3 53 can be rotated in time to make the water outlet hole 531 completely deviate from the water outlet channel 521. At this time, the water in the overflow device 5 will not flow out from the water outlet hole 531, so as to achieve the separation between the two nitrification bin bodies. In this way, while the nitrification bin body with a fault is being repaired, the other nitrification bin bodies can also continue to process the tail water in the circulating aquaculture system, thereby not affecting the entire circulating aquaculture system. In addition, in actual operation, the pipe 3 53 can be rotated to partially deviate between the water outlet hole 531 and the water outlet channel 521, so that the amount of water discharged through the water outlet hole 531 is reduced, thereby adjusting the water output of the overflow device 5. Through the above description, the overflow device 5 in this embodiment can not only adjust the flow rate of the tail water entering the nitrification bin body, but also adjust the height of the water outlet hole 531, and can also block the water flow between the two nitrification bin bodies, making the whole device more practical.

[0036] It can be understood that in this embodiment, during the actual operation, the amount of tail water in the nitrification bin body can be related to the position of the water outlet 531. Because the overflow device 5 and the connecting pipe 4 can be regarded as a communicating vessel, the position of the water outlet 531 can determine the amount of water entering the next nitrification bin body. When the nitrification bin body to be entered can process more tail water, the height of the water outlet 531 can be adjusted upward, so that the amount of tail water entering the nitrification bin body through the overflow device 5 is larger. When the volume of the nitrification bin body to be entered is small and the ability to process tail water is limited, the height of the water outlet 531 can be adjusted downward, so that the amount of tail water entering the nitrification bin body is smaller. In the actual operation, the above operation can be used to reasonably allocate the amount of tail water processed by each nitrification bin body, so that the amount of tail water processed by each nitrification bin body is within a reasonable range, thereby realizing rapid and effective treatment of tail water.

[0037] like Figure 5 and Figure 7 As shown, the water outlet channel 521 is a long strip through hole structure. The long strip through hole structure can adjust the water outlet height of the overflow device 5 by changing the relative position between the water outlet hole 531 and the water outlet channel 521, thereby adjusting the amount of tail water entering the nitrification bin body.

[0038] like Figure 1 and Figure 3As shown, the overflow device 5 also includes a cylinder 54 and a motor, the motor is fixed to the nitrification bin body through a mounting plate, one end of the cylinder 54 is connected to the pipe 3 53, and the other end of the cylinder 54 is connected to the motor, and the cylinder 54 drives the pipe 3 53 to slide along the slide cavity 524 to adjust the relative position of the water outlet hole 531 and the water outlet channel 521 in the axial direction of the pipe 2 52. By setting the cylinder 54, the cylinder 54 is connected to the pipe 3 53, so that the cylinder 54 can drive the pipe 3 53 to slide along the slide cavity 524, thereby driving the water outlet hole 531 to move upward, thereby adjusting the relative position between the water outlet hole 531 and the water outlet channel 521. In this embodiment, by adjusting the relative position between the water outlet hole 531 and the water outlet channel 521, the depth of the tail water entering the nitrification bin body can be adjusted. The motor drives the pipe three 53 to rotate along the central axis direction of the pipe two 52 through the cylinder 54 to adjust the relative position of the water outlet hole 531 and the water outlet channel 521 in the radial direction of the pipe two 52. When it is necessary to adjust the relative position of the water outlet hole 531 and the water outlet channel 521 in the radial direction of the pipe two 52, the motor can be started, and the motor can drive the pipe three 53 to rotate through the cylinder 54, so that the water outlet hole 531 on the pipe three 53 will rotate along the radial direction of the pipe two 52, thereby adjusting the relative offset between the water outlet hole 531 and the water outlet channel 521. Through the above operation, the water output of the water outlet hole 531 can be adjusted, and the water in the overflow device 5 cannot be discharged through the water outlet hole 531 by adjusting the water outlet hole 531 and the water outlet channel 521 to be completely offset, thereby isolating the water flow between the two nitrification warehouse bodies.

[0039] In this embodiment, the cylinder 54 and the motor may be directly connected, or may be connected via a flange, or may be connected via a coupling. The specific connection method may be selected according to actual needs.

[0040] like Figure 3 As shown, a connection block 1 532 is provided on the end of the second pipe 52 away from the first pipe 51, and a connection block 2 541 is provided on the end of the cylinder 54 close to the second pipe 52, and the connection block 2 541 is detachably connected to the connection block 1 532. The detachable connection facilitates the connection or disassembly between the cylinder 54 and the third pipe 53, so that the third pipe 53 can be disassembled, cleaned or replaced later.

[0041] In this embodiment, the connection block 1 532 and the connection block 2 541 can be connected by screw connection.

[0042] In other embodiments, the connection block and the second connection block 541 may be magnets, and the connection is performed by magnetic connection.

[0043] It is understandable that there can be a variety of connection methods between the connection block 1 532 and the connection block 2 541, as long as it is a detachable connection method that can be achieved between the two in the prior art.

[0044] like Figure 4 As shown, the connecting pipe 4 is an S-shaped pipe. One end of the S-shaped pipe can be connected to the water outlet of one of the nitrification bin bodies (the water outlet is located at the bottom of the nitrification bin body), and the other end of the S-shaped pipe can be connected to the water inlet of another nitrification bin body, and the water inlet is connected to the water inlet end of the pipe 1 51 in the overflow device 5, so that the water in the connecting pipe 4 can enter the pipe 1 51 through the water inlet. In this embodiment, the S-shaped pipe is vertically arranged so that the water inlet end of the S-shaped pipe is lower than the water outlet end. Therefore, the water in the nitrification bin body connected to the water inlet end of the S-shaped pipe can all enter the other nitrification bin body.

[0045] In this example, see Figure 1 and Figure 2 The number of nitrification warehouse bodies is three, and the three nitrification warehouse bodies are independently arranged. The three nitrification warehouse bodies are nitrification warehouse body 1, nitrification warehouse body 2, and nitrification warehouse body 3. The water inlet end of one of the connecting pipes 4 is connected to the water outlet of the nitrification warehouse body 1, and the water outlet end of the connecting pipe 4 is connected to the water inlet of the nitrification warehouse body 2. The water inlet end of another connecting pipe 4 is connected to the water outlet of the nitrification warehouse body 1, and the water outlet end of the connecting pipe 4 is connected to the water inlet of the nitrification warehouse body 3. The water inlet end of the third connecting pipe 4 is connected to the water outlet of the nitrification warehouse body 2, and the water outlet end of the connecting pipe 4 is connected to the water inlet of the nitrification warehouse body 3. By providing three connecting pipes 4, the nitrification bin body 1, the nitrification bin body 2 and the nitrification bin body 3 can be connected in pairs, so that when one of the nitrification bin bodies fails, the tail water can be bypassed and passed through the other two normally operating nitrification bin bodies in sequence, thereby continuing to treat the tail water, and there will be no problem that the entire tail water treatment system needs to stop operating due to the failure of one of the nitrification bin bodies, thereby improving the stability of the entire tail water treatment system. In addition, the faulty bin can be independently repaired when the tail water is being treated, so that the repair process will not interfere with the normal treatment of the tail water.

[0046] In actual operation, the number of nitrification silo bodies can be effectively combined according to the actual amount of tail water to be treated. If the amount of tail water to be treated is large, 4, 5 or more nitrification silo bodies can be selected and combined to adapt to the larger tail water volume and nitrogen load.

[0047] In the utility model, a plurality of nitrification bin bodies are freely combined and an overflow device 5 is provided in cooperation, which can not only ensure the reasonable distribution of water flow and realize the effective treatment of tail water, but also adjust the path of tail water flow under specific circumstances, so that the treatment of tail water can be in a state of continuous treatment, thereby ensuring the stability of the front-end breeding system.

[0048] In addition, the nitrification bin body also needs regular maintenance after running for a period of time. Due to the continuity of the front-end breeding system, it is very difficult to maintain the nitrification bin in the prior art when it is in working state. However, in the present invention, by setting up multiple independent nitrification bin bodies, it is possible to change the path of the tail water while ensuring that the tail water can be effectively treated and one or more of the nitrification bin bodies can be vacated, so that these vacant nitrification bin bodies can be maintained. After these nitrification bin bodies are maintained, the remaining nitrification bin bodies can be selectively vacated and maintained by changing the path of the tail water, thereby achieving the maintenance of the nitrification bin body while effectively treating the tail water.

[0049] See also Figure 1 and Figure 2 At least two water outlets 1 are provided on the nitrification bin body 1, one of which is connected to the overflow device 5 in the nitrification bin body 2 2 through a connecting pipe 4, and the other water outlet 1 is connected to the overflow device 5 in the nitrification bin body 2 2 through a connecting pipe 4. By providing two water outlets 1, the nitrification bin body 1 can be connected to the nitrification bin body 2 2 or the nitrification bin body 3 3 respectively. When the nitrification bin body 2 2 fails, the nitrification bin body 2 2 can be skipped, and the nitrification bin body 1 and the nitrification bin body 3 3 can be connected; when the nitrification bin body 3 3 fails, the nitrification bin body 3 3 can be skipped, and the nitrification bin body 1 and the nitrification bin body 2 2 can be connected. Through the above operation, even if one of the nitrification bin bodies fails in the utility model, it will not affect the treatment of tail water.

[0050] In the actual design process, the number of the water outlets 1 of the nitrification bin body 1 can be selected according to the number of nitrification bin bodies that need to be connected thereto.

[0051] See also Figure 1 and Figure 2 The nitrification bin body 2 is provided with a water outlet 2, and the water outlet 2 is connected to the overflow device 5 in the nitrification bin body 3 through a connecting pipe 4. By providing the water outlet 2, the nitrification bin body 2 and the nitrification bin body 3 can be connected, so that when the nitrification bin body 1 fails, the tail water can be directly transported to the nitrification bin body 2, and then the tail water can be processed through the nitrification bin body 2 and the nitrification bin body 3.

[0052] See also Figure 1 and Figure 2 The nitrification bin body 1 and the nitrification bin body 2 are both provided with a water inlet pipe 21, and the water inlet pipe 21 and the connecting pipe 4 are not on the same side wall of the nitrification bin body. By arranging the water inlet pipe 21 and the connecting pipe 4 on different side walls of the nitrification bin body, the tail water entering through the water inlet pipe 21 can stay in the nitrification bin body for a longer time, thereby improving the treatment effect of the nitrification bin body on the tail water.

[0053] In this embodiment, by providing the water inlet pipe 21 on both the nitrification bin body 1 and the nitrification bin body 2, if the nitrification bin body 1, the nitrification bin body 2 and the nitrification bin body 3 can all process the tail water, the water outlet pipe of the tail water can be connected to the water inlet pipe 21 of the nitrification bin body 1. When the nitrification bin body 1 fails, the water outlet pipe of the tail water can be connected to the water inlet pipe 21 of the nitrification bin body 2. In this way, the water outlet pipe of the tail water and the water inlet pipe 21 can be connected according to actual needs to achieve the purpose of adjusting the path of the tail water.

[0054] See also Figure 2 , a water outlet pipe 22 is installed on the nitrification bin body 2, the water outlet pipe 22 is connected to the nitrification bin body 2, and the water in the nitrification bin body 2 can be discharged through the water outlet pipe 22. When the nitrification bin body 3 3 fails, only the nitrification bin body 1 and the nitrification bin body 2 2 are connected, and the tail water can enter through the nitrification bin body 1, and then be processed by the nitrification bin body 1 and the nitrification bin body 2 2, and then be discharged through the water outlet pipe 22. A water outlet pipe 3 31 is provided on the nitrification bin body 3 3, the water outlet pipe 3 31 is connected to the nitrification bin body 3 3, and the water in the nitrification bin body 3 3 can be discharged through the water outlet pipe 3 31.
