Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture tail water circulation purification systems. Specifically, it particularly relates to an aquaculture tail water circulation purification system with an anti-misoperation function. Background Art

[0002] The development of the aquaculture industry is restricted by the current extreme shortage of water resources, especially the lack of a stable and clean water source. Therefore, the efficient treatment of aquaculture tail water can simultaneously achieve the recycling of aquaculture water, reduce the discharge risk of unqualified tail water, and achieve the efficient utilization of water resources.

[0003] When discharging and purifying the tail water inside the culture pond, it is necessary to discharge the tail water through the sewage outlet. At the same time, in order to prevent the fish inside the culture pond from swimming out through the sewage outlet, it is necessary to install a fence at the sewage outlet to block the fish. At this time, under the pumping of the water pump, a strong suction force is likely to appear at the sewage outlet. This phenomenon is likely to cause the fish cultured inside the culture pond to collide with the protective net under the suction force, resulting in injury to the fish. In severe cases, it is also likely to cause the death of the fish.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is an aquaculture tail water circulation purification system with an anti-misoperation function, including a culture pond. A through groove is provided on the inner wall of the culture pond. Both sides of the culture pond are fixedly connected with inclined baffle boxes. A rotating roller is rotatably connected to the inner wall of the inclined baffle box. A filter transport assembly is arranged on the outer surface of the rotating roller. The filter transport assembly is inside the culture pond through the through groove. A sewage outlet is provided at the bottom of the culture pond. An installation groove is provided on one side of the inclined baffle box. The installation groove penetrates the inclined baffle box. A blower is fixedly installed on one side of the installation groove. A collection assembly is arranged on the other side of the installation groove.

[0008] Further, the filter transport assembly includes a conveyor belt. The conveyor belt is rotatably connected to the rotating roller. A push plate is fixedly connected to the outer surface of the conveyor belt. The push plate is movably connected to the through groove and the top inner wall of the inclined baffle box. Both sides of the push plate are movably connected to the inner wall of the culture pond. Filter holes are provided on the outer surface of the conveyor belt.

[0009] Furthermore, a first guiding roller is rotatably connected to the inner wall of the inclined baffle box, the first guiding roller is movably connected to the inner wall of the conveyor belt, a second guiding roller is rotatably connected to the inner wall of the inclined baffle box, and the second guiding roller is movably connected to the upper surface of the conveyor belt.

[0010] Furthermore, a motor is fixedly installed on one side of the inclined baffle box, and the motor penetrates through the inclined baffle box and is fixedly connected to the roller.

[0011] Furthermore, the collection assembly includes a guiding frame, the guiding frame is fixedly installed on the other side of the inclined baffle box, a support box is fixedly connected to one side of the guiding frame, a collection box is movably connected inside the support box, a handle is fixedly connected to the top of the collection box, a magnetic suction door is rotatably connected to the top of the support box, and a first filter screen is fixedly connected to one side of the support box.

[0012] Furthermore, a first guiding plate is fixedly connected inside the installation groove, the first guiding plate is flush with the upper surface of the conveyor belt, the bottom of the guiding frame is flush with the bottom of the first guiding plate, a second guiding plate is fixedly connected to the top inner wall of the inclined baffle box, one side of the second guiding plate is movably connected to the push plate, the bottom of the second guiding plate is movably connected to the conveyor belt, and a second filter screen is fixedly connected between the bottom of the second guiding plate and the installation groove.

[0013] Furthermore, a suction pipe is fixedly connected to the bottom of the sewage outlet, one end of the suction pipe is fixedly connected to a filter box, a treatment box is arranged on one side of the filter box, an aeration box is arranged on one side of the aquaculture pond, the filter box, the treatment box and the aeration box are connected together through a connecting pipe, a discharge pipe is fixedly connected to the top of the aeration box, and a water pump is arranged on the outer surface of the suction pipe.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the utility model purifies the tail water, the tail water inside the aquaculture pond can directly penetrate to the lower side of the conveyor belt through the filter holes on the conveyor belt. At this time, the water pump extracts the penetrated tail water through the sewage outlet and the suction pipe. During the above working process, since the conveyor belt covers the entire aquaculture pond, the conveyor belt can block the suction force generated at the sewage outlet, so that the suction force generated at the sewage outlet will not suck the fish inside the aquaculture pond. At the same time, the setting of the filter holes enables the tail water to be normally extracted by the water pump through the sewage outlet.

At this time, the top inner wall of the inclined baffle box, the conveyor belt, the push plate, the first baffle and the second baffle can form a channel, and the impurities are inside the channel. Then, the blower blows the impurities on the conveyor belt, and makes the impurities move inside the above channel and directly fall into the collection box through the guiding frame, so that the collection box can filter the impurities. The above settings can clean the impurities falling on the conveyor belt, so that there will be no impurity accumulation on the conveyor belt, and at the same time, it can also reduce some burdens on the subsequent filter box for filtering the tail water.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0030] Please refer to Figures 1-7 As shown in the figure, the present utility model is an aquaculture tail water circulation purification system with an anti-misoperation function, including a breeding pond 1. It is characterized in that through grooves 2 are provided on the inner wall of the breeding pond 1, inclined baffle boxes 3 are fixedly connected to both sides of the breeding pond 1, rotating rollers 4 are rotatably connected to the inner walls of the inclined baffle boxes 3, a filter transportation component 5 is arranged on the outer surface of the rotating rollers 4, the filter transportation component 5 is located inside the breeding pond 1 through the through grooves 2, a sewage outlet 6 is provided at the bottom of the breeding pond 1, an installation groove 7 is provided on one side of the inclined baffle box 3, the installation groove 7 penetrates through the inclined baffle box 3, a fan 20 is fixedly installed on one side of the installation groove 7, and a collection component 8 is arranged on the other side of the installation groove 7.

[0031] The rotating roller 4 drives the filtering and transporting assembly 5 to rotate inside the aquaculture pond 1 and the two inclined baffle boxes 3. At this time, the tail water inside the aquaculture pond 1 seeps down through the filtering and transporting assembly 5. At the same time, the seeping tail water flows out of the aquaculture pond 1 along the sewage outlet 6. The impurities falling on the filtering and transporting assembly 5 are driven by the filtering and transporting assembly 5 to move into the inclined baffle box 3 on one side of the aquaculture pond 1. At this time, the blower 20 blows the impurities on the transporting assembly 5, and makes the impurities fall into the collecting assembly 8 through another mounting groove 7.

[0032] The tail water inside the aquaculture pond 1 can first seep down from the filtering assembly 5 and then flow out of the aquaculture pond 1 through the sewage outlet 6. At this time, since the filtering and transporting assembly 5 can block the suction force generated at the sewage outlet 6, the suction force generated at the sewage outlet 6 will not suck the fish inside the aquaculture pond 1. This setting avoids the phenomenon that fish are injured or die due to the suction force. At the same time, the impurities falling on the filtering and transporting assembly 5 can be driven into the inclined baffle box 3. At this time, the impurities can directly fall into the collecting assembly 8 under the blowing of the blower 20. This setting prevents the phenomenon of impurity accumulation on the filtering and transporting assembly 5.

[0033] In one embodiment, for the above-mentioned filtering and transporting assembly 5, the filtering and transporting assembly 5 includes a conveyor belt 501. The conveyor belt 501 is rotatably connected to the rotating roller 4. A push plate 502 is fixedly connected to the outer surface of the conveyor belt 501. The push plate 502 is movably connected to the top inner walls of the through groove 2 and the inclined baffle box 3. Both sides of the push plate 502 are movably connected to the inner wall of the aquaculture pond 1. Filter holes 503 are formed in the outer surface of the conveyor belt 501.

[0034] The tail water inside the aquaculture pond 1 can directly seep to the lower side of the conveyor belt 501 through the filter holes 503. At the same time, the rotating roller 4 can drive the conveyor belt 501 to rotate, so that the impurities accumulated on the conveyor belt 501 can be directly moved into the inclined baffle box 3 under the drive of the push plate 502. The setting of the push plate 502 prevents the impurities from sliding down when the conveyor belt 501 transports the impurities obliquely upward. At the same time, the blower 20 and the collecting assembly 8 can better collect the impurities. The setting of the filter holes 503 enables the conveyor belt 501 to block the suction force generated at the sewage outlet 6, and at the same time, the tail water can normally pass through the conveyor belt 501 through the filter holes 503.

[0035] In one embodiment, for the above-mentioned inclined baffle box 3, a first guiding roller 9 is rotatably connected to the inner wall of the inclined baffle box 3. The first guiding roller 9 is movably connected to the inner wall of the conveyor belt 501. A second guiding roller 10 is rotatably connected to the inner wall of the inclined baffle box 3. The second guiding roller 10 is movably connected to the upper surface of the conveyor belt.

[0036] When the conveyor belt 501 moves, it can drive the first guide roller 9 and the second guide roller 10 to rotate. The cooperation between the first guide roller 9 and the second guide roller 10 enables the conveyor belt 501 to be properly inclined inside the inclined baffle box 3, so that the impurities on the conveyor belt 501 can be cleaned without the presence of tail water on the conveyor belt 501, thus separating the impurities from the tail water.

[0037] In one embodiment, for the above-mentioned motor 11, a motor 11 is fixedly installed on one side of the inclined baffle box 3, and the motor 11 penetrates the inclined baffle box 3 and is fixedly connected to the roller 4.

[0038] By driving the motor 11, the motor 11 drives the roller 4 to rotate, and the roller 4 drives the conveyor belt 501 to rotate. The setting of the motor 11 enables the transportation and filtration assembly 5 to automatically rotate inside the breeding pond 1 and the two inclined baffle boxes 3.

[0039] In one embodiment, for the above-mentioned collection assembly 8, the collection assembly 8 includes a guide frame 801. The guide frame 801 is fixedly installed on the other side of the inclined baffle box 3. One side of the guide frame 801 is fixedly connected to a support box 802. Inside the support box 802, there is a movable connection with a collection box 803. The top of the collection box 803 is fixedly connected to a handle 804. The top of the support box 802 is rotatably connected to a magnetic door 805. One side of the support box 802 is fixedly connected to a first filter screen 806.

[0040] The impurities can roll into the inside of the guide frame 801 under the blowing of the fan 20. At the same time, under the guidance of the guide frame 801, the impurities can directly fall into the inside of the collection box 803. The following air flow then flows out of the inside of the support box 802 through the first filter screen 806. When cleaning the impurities collected inside the collection box 803, directly rotate the magnetic door 805 so that the magnetic door 805 no longer blocks the top of the collection box 803. Then, through the handle 804, the collection box 803 can be lifted out of the inside of the support box 802, and then the impurities inside the collection box 803 can be cleaned. The setting of the first filter screen 806 enables the air flow blown by the fan 20 not to blow the impurities collected inside the collection box 803, and at the same time, the collection box 803 that can be moved out of the inside of the support box 802 makes it more convenient to clean the impurities collected inside the collection box 803.

[0041] In one embodiment, for the above-mentioned installation groove 7, a first guide plate 12 is fixedly connected inside the installation groove 7. The upper surface of the first guide plate 12 is flush with the upper surface of the conveyor belt 501. The bottom of the guide frame 801 is flush with the bottom of the first guide plate 12. The top of the inner wall of the inclined baffle box 3 is fixedly connected with a second guide plate 13. One side of the second guide plate 13 is movably connected with the push plate 502. The bottom of the second guide plate 13 is movably connected with the conveyor belt 501. A second filter screen 21 is fixedly installed between the bottom of the second guide plate 13 and the installation groove 7.

[0042] The first guide plate 12 divides the installation groove 7 on one side of the inclined baffle box 3 into two parts. Mainly impurities pass between the upper side of the first guide plate 12 and the inner wall of the top of the installation groove 7. A channel can be formed among the first guide plate 12, the second guide plate 13, the push plate 502 and the inner wall of the top of the inclined baffle box 3. This setting enables the fan 20 to better blow the impurities on the conveyor belt 501 into the inside of the guide frame 801. Mainly air flows between the lower side of the first guide plate 12 and the inner wall of the bottom of the installation groove 7. At this time, the fan 20 can blow the inner wall of the conveyor belt 502, so that the inner wall of the conveyor belt 502 is relatively dry under the blowing of the air flow. At the same time, the flowing air flow can flow out from the second filter screen 21. This setting makes it not easy for the roller 4 to drive the conveyor belt 501 to rotate and slip.

[0043] In one embodiment, for the above-mentioned sewage outlet 6, a suction pipe 14 is fixedly connected to the bottom of the sewage outlet 6. One end of the suction pipe 14 is fixedly connected with a filter box 15. A treatment box 16 is arranged on one side of the filter box 15. An aeration box 17 is arranged on one side of the breeding pond 1. The filter box 15, the treatment box 16 and the aeration box 17 are connected together through a connecting pipe 22. A discharge pipe 18 is fixedly connected to the top of the aeration box 17. A water pump 19 is arranged on the outer surface of the suction pipe 14.

[0044] The water pump 19 can extract the permeated tail water through the suction pipe 14 and the sewage outlet 6. The extracted tail water flows into the inside of the filter box 15 for filtration. The filtered tail water flows into the inside of the treatment box 16 for disinfection under the guidance of the connecting pipe 22. The disinfected tail water flows into the inside of the aeration box 17 for oxygen supply under the guidance of the transport pipe 22. At this time, the discharge pipe 18 transports the purified and oxygen-rich tail water back into the inside of the breeding pond 1 again. With the mutual cooperation of the above-mentioned devices, the tail water can be purified, so that the tail water can be recycled.

[0045] Through the above technical solutions: 1. When purifying the tail water, the tail water inside the aquaculture pond 1 can directly penetrate to the lower side of the conveyor belt 501 through the filter holes 503 on the conveyor belt 501. At this time, the water pump 19 extracts the penetrated tail water through the sewage outlet 6 and the extraction pipe 14. During the above operation process, since the conveyor belt covers the entire aquaculture pond 1, the conveyor belt 501 can block the suction force generated at the sewage outlet 6, so that the suction force generated at the sewage outlet 6 will not suck the fish inside the aquaculture pond 1. At the same time, the setting of the filter holes 503 enables the tail water to be normally extracted by the water pump 19 through the sewage outlet 6. The above setting enables the tail water to be discharged normally while avoiding the phenomenon that fish are injured or killed due to the suction force. 2. The motor 11 can drive the conveyor belt 501 to rotate inside the aquaculture pond 1 and the two inclined baffle boxes 3 through the roller 4. At this time, the impurities falling on the conveyor belt 501 can be moved into the inclined baffle box 3 on one side of the aquaculture pond 1 under the drive of the conveyor belt 501. At this time, the top inner wall of the inclined baffle box 3, the conveyor belt 501, the push plate 502, the first baffle 12 and the second baffle 13 can form a channel, and the impurities are inside the channel. Then the fan 20 blows the impurities on the conveyor belt 501 and makes the impurities move inside the above channel and directly fall into the collection box 803 through the guiding frame 801, so that the collection box 803 can filter the impurities. The above setting enables the impurities falling on the conveyor belt 801 to be cleaned up, so that there will be no impurity accumulation on the conveyor belt 801, and at the same time, it can also reduce some burdens on the subsequent filter tank 15 when filtering the tail water.
