Description

Technical Field

[0001] The invention relates to the technical field of aquaculture tail water treatment, and in particular to an energy-saving and environment-friendly tail water treatment device for aquaculture. Background Art

[0002] In the process of aquaculture, it is necessary to frequently treat and replace the water used for aquaculture. The water that needs to be treated is called tail water. Tail water usually needs to be precipitated in a sedimentation tank, and then filtered and purified through a filter dam and a sand filter tower. The filtered water is then treated with microorganisms and aerated, and then goes through multi-stage purification processes such as ecological ditch purification and ecological pond purification. At this time, the tail water can be used again. The tail water contains pollutants such as leftover bait, feces, and drugs, so it cannot be discharged directly. Direct discharge will lead to eutrophication of the water body. At the same time, good treatment of tail water can improve the aquaculture environment, reduce the risk of disease, and increase production and quality.

[0003] The commonly used method for tail water treatment in aquaculture is the three-tank and two-dam method, which includes a sedimentation tank, an aeration tank, an ecological purification tank and two filter dams. The filter dam is set between the three tanks. The tail water is filtered through the filter dam after sedimentation in the sedimentation tank, and then aerated in the aeration tank, and then enters the ecological purification tank through another filter dam. The traditional filter dam contains expanded clay, volcanic stone, etc., which are used to adsorb and filter suspended matter. The tail water in the sedimentation tank will have more sediment. At the same time, due to the eutrophication surface, a large amount of suspended matter and algae will be produced. In actual use, there is a problem of weak pollution absorption capacity of the filter dam, and the cleaning of the filter material is more troublesome, so that most filter dams need to clean the filter material frequently, otherwise the filtering effect may be poor. Summary of the invention

[0012] The working principle and beneficial effects of the present invention are: 1. In the present invention, a cover sheet and a conveying hole are provided. When the propeller blade rotates so that the cover sheet is aligned with the conveying hole, the cover sheet blocks the conveying hole, and the sediment cannot leave. The sediment contacts the propeller blade through the opening on the side of the separation cylinder and is pushed by the rotation of the propeller blade. At this time, the sediment accumulates at one end of the separation cylinder close to the conveying hole. When the cover sheet is not aligned with the conveying hole, the sediment flows toward the discharge groove through the conveying hole. When the cover sheet is aligned with the conveying hole, the sediment accumulates and is squeezed at the conveying hole. The fan-shaped setting of the cover sheet and the conveying hole makes the sedimentation tank blocked when the cover sheet is aligned with the conveying hole, so as to prevent the tail water from flowing out through the conveying hole when the sediment has not been completely precipitated. At the same time, when the sediment is discharged, due to the small conveying hole, the sediment will be repeatedly squeezed, which will also make the water content in the sediment less. 2. In the present invention, a collecting tank and a floating block are provided. The collecting tank floats on the water surface through the floating block, and rises and falls with the water level. The storage bin can be sunk into the water through the counterweight block. The side of the collecting tank away from the storage bin is provided in a shovel shape, and the side of the shovel shape is flush with the water surface. The floating objects floating on the water surface are collected, and the floating objects flow into the storage bin. Then, the water pump sucks up the floating objects in the storage bin through the suction pipe and discharges them into the discharge tank, and the sediment is discharged through the discharge hole. The buoyancy of the floating block makes the collecting tank rise and fall with the water level. By providing a return track, it is avoided to open holes on the sides of the sealing frame 1 and the sealing frame 2, and it is avoided that the tail water in the sedimentation tank flows into the sealing frame 1 and the sealing frame 2. 3. In the present invention, a sediment cleaning mechanism and a suspended matter cleaning mechanism are provided to clean the bottom sediment in the sedimentation tank and the floating objects on the water surface respectively. The impurities in the tail water of the sedimentation tank are mainly in the sediment at the bottom of the tank and the floating objects on the surface.

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 to Figure 6 As shown, this embodiment proposes an energy-saving and environmentally friendly tailwater treatment device for aquaculture, including a slope 1, a filter material installation groove 2 is opened on the slope 1, the filter material installation groove 2 is opened in the center of the slope 1, and a sedimentation tank 3 and an aeration tank 4 are respectively arranged on both sides of the filter material installation groove 2. It also includes filter material 5, a sealing frame mechanism, a sediment cleaning mechanism and a suspended matter cleaning mechanism. A plurality of filter materials 5 are provided, and the plurality of filter materials 5 can be detachably installed in the filter material installation groove 2. The sealing frame mechanism is arranged on the slope 1, and the sealing frame mechanism is detachably connected to the filter material 5. The sealing frame mechanism is used to fix the filter material 5. The sediment cleaning mechanism is arranged on the slope 1 and the sealing frame mechanism. The sediment cleaning mechanism is used to separate and discharge the sediment in the sedimentation tank 3. The sediment cleaning mechanism includes a separation cylinder 11, and the separation cylinder 11 is fixedly connected to the bottom of the sedimentation tank 3. The separation cylinder 11 is used to accommodate the sediment at the bottom of the sedimentation tank 3. The suspended matter cleaning mechanism is arranged on the sealing frame mechanism. The suspended matter cleaning mechanism is used to separate and discharge the suspended matter in the sedimentation tank 3.

[0018] like Figure 1~Figure 3 As shown, the sealing frame mechanism includes a sealing frame 1 7 and a sealing frame 2 8. The sealing frame 1 7 is opened on one side of the slope 1, and the sealing frame 1 7 is not connected to the sedimentation tank 3 and the aeration tank 4. The sealing frame 1 7 is detachably connected to the filter material 5. The sealing frame 2 8 is opened on the side of the slope 1 away from the sealing frame 1 7. The sealing frame 2 8 is not connected to the aeration tank 4, and the sealing frame 2 8 is detachably connected to the filter material 5. The suspended matter cleaning mechanism includes a collecting tank 6, and the collecting tank 6 is slidably arranged on the sealing frame mechanism. A lifting tank 9 is opened on the side of the sealing frame 1 and the sealing frame 2 8 close to the sedimentation tank 3. The collecting tank 6 is slidably arranged on the lifting tank 9. The sealing frame 1 7 and the sealing frame 2 8 are tightly fitted with the filter material 5, so that the water in the sedimentation tank 3 must be filtered into the aeration tank 4 through the filter material 5.

[0019] like Figure 1~Figure 5As shown, the sediment cleaning mechanism is arranged on the side of the filter material 5 close to the sedimentation tank 3, and the sediment cleaning mechanism includes a motor 10, a conveying hole 12 and a propeller blade 13. The motor 10 is fixedly installed in the sealing frame 1 7, and the two ends of the separation cylinder 11 are fixedly connected to the sealing frame 1 7 and the sealing frame 2 8 respectively. The conveying hole 12 is opened on the sealing frame 2 8, and the conveying hole 12 is connected with the separation cylinder 11. The propeller blade 13 is rotatably arranged on the separation cylinder 11 and the sealing frame 2 8. The output end of the motor 10 is connected with the propeller blade 13 in a transmission manner. In the process of water in the sedimentation tank 3 flowing toward the aeration tank 4 through the filter material 5, the sediment at the bottom of the sedimentation tank 3 moves toward the separation cylinder 11 with the water flow, and the output end of the motor 10 drives the propeller blade 13 to rotate, and the propeller blade 13 drives the sediment to move toward the conveying hole 12, and the sediment is conveyed to the discharge tank 20 through the conveying hole 12, thereby reducing the contact between the sediment and the filter material 5 and reducing the amount of dirt adsorbed in the filter material 5. Then the sediment is discharged through the discharge hole.

[0020] like Figure 5~Figure 6 As shown, the separation cylinder 11 is set to a C shape, and the separation cylinder 11 is fixedly set at the bottom of the sedimentation tank 3. The opening on the separation cylinder 11 faces one side of the sedimentation tank 3, and the conveying hole 12 is set to a fan shape. The end of the propeller blade 13 close to the sealing frame 28 is in contact with the conveying hole 12, and the side of the propeller blade 13 that is in contact with the conveying hole 12 is fixedly connected with a cover plate 23. When the propeller blade rotates to align the cover plate 23 with the conveying hole 12, the cover plate blocks the conveying hole 12, and the sediment cannot leave. The sediment contacts the propeller blade 13 through the opening on the side of the separation cylinder 11 and is pushed by the rotation of the propeller blade 13. When the cover sheet 23 is aligned with the conveying hole 12, the sediment accumulates at one end of the separation cylinder 11 close to the conveying hole 12. When the cover sheet 23 is not aligned with the conveying hole 12, the sediment flows toward the discharge trough 20 through the conveying hole 12. When the cover sheet 23 is aligned with the conveying hole 12, the sediment accumulates and is squeezed at the conveying hole 12. Through the fan-shaped setting of the cover sheet 23 and the conveying hole 12, the sedimentation tank 3 is blocked when the cover sheet 23 is aligned with the conveying hole 12, preventing the tail water from flowing out through the conveying hole 12 when the sediment has not completed sedimentation. At the same time, when the sediment is discharged, due to the small conveying hole 12, the sediment will be repeatedly squeezed, which will also make the water content in the sediment less.

[0021] like Figure 3~Figure 4As shown, the suspended matter cleaning mechanism is arranged on the side of the filter material 5 close to the sedimentation tank 3, and the suspended matter cleaning mechanism also includes a return track 14 and a water pump 15. There are two return tracks 14, and the two return tracks 14 are respectively fixedly connected to the two sides of the collecting tank 6, and the two return tracks 14 are respectively slidably connected to the lifting tank 9. The water pump 15 is fixedly installed in the sealing frame 8. A suction pipe 16 is fixedly connected to the water inlet of the water pump 15, and the suction pipe 16 is fixedly connected to the return track 14 close to the sealing frame 8. The suction pipe 16 extends into the collecting tank 6. The parts of the two return tracks 14 that are respectively located in the sealing frame 1 7 and the sealing frame 2 8 are rotatably connected with a plurality of rollers, and the rollers are in contact with the lifting tank 9. A storage bin 17, a floating block 18 and a counterweight block 19 are provided on the collecting tank 6. The storage bin 17 is opened on the side of the collecting tank 6 close to the filter material 5, and the suction pipe 16 extends into the storage bin 17. In the embodiment, two floating blocks 18 are provided, and the two floating blocks 18 are fixedly connected to the two sides of the collecting tank 6 respectively, and the counterweight block 19 is fixedly connected to the collecting tank 6. Through the floating blocks 18, the collecting tank 6 floats on the water surface, and rises and falls with the water level. Through the counterweight block 19, the receiving bin 17 can be sunk into the water. The side of the collecting tank 6 away from the receiving bin 17 is set to be shovel-shaped, and the side of the shovel-shaped side is flush with the water surface. The floating objects floating on the water surface are collected, and the floating objects flow into the receiving bin 17. Then the water pump 15 sucks up the floating objects in the receiving bin 17 through the suction pipe 16 and discharges them into the discharge tank 20, and discharges them with the sediment through the discharge hole. Through the buoyancy of the floating blocks 18, the collecting tank 6 rises and falls with the water level. Through the setting of the return track 14, it is avoided to open holes on the sides of the sealing frame 1 7 and the sealing frame 2 8, and it is avoided that the tail water in the sedimentation tank 3 flows into the sealing frame 1 7 and the sealing frame 2 8.

[0022] like Figure 6 As shown, a discharge groove 20, a driving cylinder 21 and a scraping block 22 are provided in the sealing frame 8. The discharge groove 20 is fixedly connected in the sealing frame 8. The conveying hole 12 is communicated with the discharge groove 20. A discharge hole is opened on the side of the discharge groove 20, and the discharge hole passes through the slope body 1. The driving cylinder 21 is fixedly installed on the slope body 1. The output end of the driving cylinder 21 extends into the discharge groove 20. The scraping block 22 is fixedly connected to the output end of the driving cylinder 21. The side of the scraping block 22 close to the discharge hole is set to be vertical, and the side away from the discharge hole is set to be inclined. When the output end of the driving cylinder 21 is shortened, the scraping block 22 is pulled, and the vertical side pushes the sediment in the discharge groove 20 to move. When the output end of the driving cylinder 21 is extended, the inclined surface on the scraping block 22 pushes the sediment to shovel up, so as to facilitate the scraping out of the sediment.

[0023] The working principle of this energy-saving and environmentally friendly tailwater treatment device for aquaculture is: The tail water is discharged into the sedimentation tank 3 for sedimentation, and at the same time, the water is filtered through the filter material 5 and enters the aeration tank 4. The sediment at the bottom of the tank and the floating objects on the water surface pass through the filter material 5 with the water. At this time, the motor 10 is started, and the sediment moves into the separation cylinder 11. The propeller blades 13 rotate to push the sediment toward the conveying hole 12. The sediment moves to the discharge tank 20 through the conveying hole 12, and the suspended matter on the water surface moves to the storage bin 17 in the collection tank 6. The collection tank 6 floats on the water surface through the floating block 18 and the counterweight block 19, and the suspended matter moves to the storage bin 17. The water pump 15 sucks the sewage in the storage bin 17 into the discharge tank 20 through the suction pipe 16, and the output end of the drive cylinder 21 pulls the scraping block 22 to scrape and discharge the sediment and suspended matter in the discharge tank 20.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
