Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tail water treatment for aquaculture, in particular to an energy-saving and environmentally-friendly tail water treatment device for aquaculture. BACKGROUND

[0002] In the process of aquaculture, the water used for cultivation needs to be treated and replaced frequently. The water that needs to be treated is called tail water. The 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. After that, the filtered water is treated by microorganisms and aerated, and then purified by an ecological ditch and an ecological pond, etc. At this time, the tail water can be used again. The tail water contains pollutants such as leftover feed, feces, and drugs, so it cannot be directly discharged. Direct discharge will lead to eutrophication of the water body. At the same time, good treatment of the tail water can improve the breeding environment, reduce the risk of disease, and improve the yield and quality.

[0003] A commonly used method in the tail water treatment method for aquaculture is the three-tank two-dam method, which includes a sedimentation tank, an aeration tank, an ecological purification tank, and two filter dams. The filter dams are arranged between the three tanks. The tail water is precipitated in the sedimentation tank and then filtered through the filter dam. After that, it is aerated in the aeration tank and then enters the ecological purification tank through another filter dam. The traditional filter dam contains ceramic particles, volcanic rocks, etc. for adsorption and filtration of suspended solids. The tail water in the sedimentation tank has a lot of sediment. At the same time, due to eutrophication, a large amount of suspended solids and algae are produced on the surface. In actual use, the filter dam has a weak pollution capacity, and the cleaning of the filter material is troublesome. Therefore, most filter dams need to be cleaned frequently, otherwise the filtration effect may be poor. SUMMARY

[0004] The present application proposes an energy-saving and environmentally-friendly tail water treatment device for aquaculture, which solves the problem of poor pollution capacity of the filter material in the traditional filter dam and the need for frequent cleaning of the filter material.

[0005] The technical solution of the present application is as follows:

[0006] The utility model provides an energy -conserving and environmental protection tail water treatment device for aquaculture, including slope body, filter material installation groove is set up in slope body, filter material installation groove sets up in the central part of slope body, both sides of filter material installation groove are provided with sedimentation tank and aeration tank respectively, still include filter material, sealing frame mechanism, sediment cleaning mechanism and suspended solid cleaning mechanism, filter material is provided with a plurality of, a plurality of filter material can detachable installation in filter material installation groove, sealing frame mechanism sets up on slope body, sealing frame mechanism with filter material is detachable connection, sealing frame mechanism is used for fixing filter material, sediment cleaning mechanism sets up on slope body with sealing frame mechanism, sediment cleaning mechanism is used for separating and discharging the sediment in sedimentation tank, sediment cleaning mechanism includes separation cylinder, separation cylinder fixedly connected in the bottom of sedimentation tank, separation cylinder is used for containing the sediment of sedimentation tank bottom, suspended solid cleaning mechanism sets up on sealing frame mechanism, suspended solid cleaning mechanism is used for separating and discharging the suspended solid in sedimentation tank, wherein, the suspended solid cleaning mechanism is provided with, collection groove collection groove is slidably arranged on the sealing frame mechanism.

[0007] The sealing frame mechanism includes a sealing frame one and a sealing frame two. The sealing frame one is set on one side of the slope body and does not communicate with the sedimentation tank and the aeration tank. The sealing frame one is detachably connected with the filter material. The sealing frame two is set on the side of the slope body away from the sealing frame one and does not communicate with the aeration tank. The sealing frame two is detachably connected with the filter material. The suspended solid cleaning mechanism includes a collection groove, which is slidably arranged on the sealing frame mechanism. Lifting grooves are set on the side of the sealing frame one and the sealing frame two close to the sedimentation tank. The collection groove is slidably arranged in the lifting grooves.

[0008] The sediment cleaning mechanism is set on the side of the filter material close to the sedimentation tank. The sediment cleaning mechanism includes a motor, a conveying hole, and a propeller blade. The motor is fixedly installed in the sealing frame one. The conveying hole is set in the sealing frame two and communicates with the separation cylinder. The propeller blade is rotatably arranged on the separation cylinder and the sealing frame two. The output end of the motor is drivingly connected with the propeller blade. The two ends of the separation cylinder are fixedly connected with the sealing frame one and the sealing frame two.

[0009] The separation cylinder is set as a C type and is fixedly arranged on the bottom of the sedimentation tank. The opening on the separation cylinder faces the side of the sedimentation tank. The conveying hole is set as a fan shape. The end of the propeller blade close to the sealing frame two is fitted with the conveying hole. The side of the propeller blade fitted with the conveying hole is fixedly connected with a cover sheet.

[0010] The suspension cleaning mechanism is arranged on the side of the filter material close to the sedimentation tank, and further comprises two return tracks, a water pump, etc.

[0011] The collecting groove is provided with a receiving bin, floating blocks and a counterweight.

[0012] The sealing frame two is provided with a discharge groove, a drive cylinder and a scraping block.

[0013] The working principle and advantages of the present application are as follows:

[0014] 1. In the present application, the covering plate blocks the delivery hole when the propeller blade rotates to align the covering plate with the delivery hole, so that the sediment cannot leave. The sediment contacts the propeller blade through the opening on the side of the partition cylinder and is pushed by the rotating propeller blade. At this time, the sediment accumulates at the end of the partition cylinder close to the delivery hole. When the covering plate is not aligned with the delivery hole, the sediment flows through the delivery hole towards the discharge groove. When the covering plate is aligned with the delivery hole, the sediment accumulates and is squeezed at the delivery hole. The fan-shaped arrangement of the covering plate and the delivery hole ensures that the sedimentation tank is blocked when the covering plate is aligned with the delivery hole, preventing the tail water from flowing out through the delivery hole before the sedimentation is completed. At the same time, when the sediment is discharged, the sediment is repeatedly squeezed due to the small size of the delivery hole, resulting in less water in the sediment.

[0015] 2. The present invention provides a collecting trough and a floating block. The collecting trough floats on the water surface through the floating block and rises and falls with the water level. The collecting bin is sunk into the water by the counterweight block. The side of the collecting trough away from the collecting bin is configured in a shovel shape. The shovel-shaped side is flush with the water surface to collect floating objects on the water surface. The floating objects flow into the collecting bin. After that, the water pump sucks up the floating objects in the collecting bin through the suction pipe and discharges them into the discharge trough, where they are discharged together with the sediment through the discharge hole. The buoyancy of the floating block allows the collecting trough to rise and fall with the water level. The provision of a return track avoids opening holes on the sides of the sealing frame 1 and the sealing frame 2, thereby preventing the tail water in the sedimentation tank from flowing into the sealing frame 1 and the sealing frame 2.

[0016] 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 in the sedimentation tank are mainly in the sediment at the bottom of the tank and the floating objects on the surface. By discharging them in a targeted manner, the amount of dirt that the filter material needs to filter can be greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] 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 embodiments described 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 making any creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 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 provided 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 provided 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 provided 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 separating cylinder 11, and the separating cylinder 11 is fixedly connected to the bottom of the sedimentation tank 3. The separating cylinder 11 is used to accommodate the sediment at the bottom of the sedimentation tank 3. The suspended matter cleaning mechanism is provided on the sealing frame mechanism. The suspended matter cleaning mechanism is used to separate and discharge the suspended matter in the sedimentation tank 3.

[0027] like Figures 1 to 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. 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. The sealing frame 2 8 is detachably connected to the filter material 5. The suspended matter cleaning mechanism includes a collecting tank 6, which is slidably arranged on the sealing frame mechanism. A lifting tank 9 is provided 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.

[0028] like Figures 1 to 5As shown, the sediment cleaning mechanism is arranged at the side of the filter material 5 close to the sedimentation tank 3, and the sediment cleaning mechanism comprises a motor 10, a conveying hole 12 and a propeller blade 13. The motor 10 is fixedly installed in the sealing frame one 7, and the two ends of the partition cylinder 11 are fixedly connected with the sealing frame one 7 and the sealing frame two 8 respectively. The conveying hole 12 is arranged on the sealing frame two 8 and communicates with the partition cylinder 11. The propeller blade 13 is rotatably arranged on the partition cylinder 11 and the sealing frame two 8. The output end of the motor 10 is in transmission connection with the propeller blade 13. During the flowing of the water in the sedimentation tank 3 to the aeration tank 4 through the filter material 5, the sediment at the bottom of the sedimentation tank 3 moves to the partition cylinder 11 along with the water flow. The output end of the motor 10 drives the propeller blade 13 to rotate, and the propeller blade 13 drives the sediment to move to the conveying hole 12. The sediment is conveyed to the discharge groove 20 through the conveying hole 12, so as to reduce the contact between the sediment and the filter material 5, reduce the amount of adsorbed dirt in the filter material 5, and then the sediment is discharged through the discharge hole.

[0029] As shown in Figure 5~Figure 6 , the partition cylinder 11 is arranged in a C shape, and is fixedly arranged at the bottom of the sedimentation tank 3. The opening on the partition cylinder 11 faces one side of the sedimentation tank 3. The conveying hole 12 is arranged in a fan shape. One end of the propeller blade 13 close to the sealing frame two 8 is in abutment with the conveying hole 12. The side of the propeller blade 13 in abutment with the conveying hole 12 is fixedly connected with a covering piece 23. When the propeller blade rotates to align the covering piece 23 with the conveying hole 12, the covering piece 23 blocks the conveying hole 12, so that the sediment cannot leave. The sediment contacts the propeller blade 13 through the opening on the side of the partition cylinder 11, and is pushed by the propeller blade 13. At this time, the sediment accumulates at one end of the partition cylinder 11 close to the conveying hole 12. When the covering piece 23 is not aligned with the conveying hole 12, the sediment flows to the discharge groove 20 through the conveying hole 12. When the covering piece 23 is aligned with the conveying hole 12, the sediment accumulates and is extruded at the conveying hole 12. Through the fan-shaped arrangement of the covering piece 23 and the conveying hole 12, when the covering piece 23 is aligned with the conveying hole 12, the sedimentation tank 3 is blocked, so as to avoid that the tail water flows out through the conveying hole 12 when the sedimentation is not completed. At the same time, when the sediment is discharged, the sediment is repeatedly extruded due to the small size of the conveying hole 12, so that the moisture in the sediment is less.

[0030] As shown in 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 fixedly connected to the two sides of the collecting tank 6 respectively. The two return tracks 14 are slidably connected to the lifting tank 9 respectively. The water pump 15 is fixedly installed in the sealing frame 2 8. The water inlet of the water pump 15 is fixedly connected with a suction pipe 16, and the suction pipe 16 is fixedly connected to the return track 14 close to the sealing frame 2 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. The collecting tank 6 is provided with a storage bin 17, a floating block 18 and a counterweight block 19. 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. The counterweight block 19 allows the receiving bin 17 to sink into the water. The side of the collecting tank 6 away from the receiving bin 17 is set to be shovel-shaped, and the shovel-shaped side is flush with the water surface, so as to collect floating objects floating on the water surface, 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 trough 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, so as to avoid the tail water in the sedimentation tank 3 from flowing into the sealing frame 1 7 and the sealing frame 2 8.

[0031] 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 to the sealing frame 8, and 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 1. The driving cylinder 21 is fixedly installed on the slope 1, and 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, which is convenient for scraping out the sediment.

[0032] The working principle of this energy-saving and environmentally friendly tailwater treatment device for aquaculture is:

[0033] The tail water is discharged into the sedimentation tank 3 for sedimentation. 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 delivery hole 12. The sediment moves to the discharge trough 20 through the delivery hole 12, and the suspended matter on the water surface moves to the storage bin 17 in the collection tank 6. The floating block 18 and the counterweight block 19 make the collection tank 6 float on the water surface, 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 trough 20 through the suction pipe 16. 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 trough 20.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
