Description

Technical Field

[0001] The invention relates to the technical field of aquaculture wastewater treatment, in particular to a tailwater treatment device for industrial aquaculture. Background Art

[0002] With the rapid development of aquaculture, the problem of wastewater discharge has become increasingly prominent. These wastewaters contain a large amount of pollutants, such as ammonia nitrogen, nitrite, organic pollutants, phosphorus and fouling organisms, which have caused serious pollution to the water environment. Secondly, through the treatment of aquaculture wastewater by various methods such as physical, chemical and biological methods, resources can be reused, such as using the treated water for agricultural irrigation or recycling it for aquaculture, thereby improving the utilization efficiency of water resources.

[0003] The treatment of aquaculture tail water can be achieved through three-stage filtration, namely physical filtration, biological filtration and chemical filtration. Drip filtration will be used to remove large particles of impurities and suspended matter in the water. Drip filtration is a physical filtration method and is usually classified as primary filtration in a three-stage filtration system. Drip filtration allows water to pass through one or more filter material layers by the natural fall or pumping of water. These filter materials can be sand, filter screens, sponges, etc. They can effectively intercept solid particles in the water, thereby achieving the purpose of purifying water quality.

[0004] However, the water inlet pipe is usually fixed and has multiple leakage holes at the bottom of the pipe. Water flows out of the leakage holes and falls on the filter material below for filtration, which will cause uneven distribution of water on the filter plate, which means that the filter material in some areas may be impacted by strong water flow, while other areas may not be covered by enough water flow, thereby affecting the filtration efficiency.

When the inclined plate 5 rotates in the direction away from the filter plate 2, the water flowing on the inclined plate 5 will fall on the filter plate 2 at a position farther from the fixed rod 3. At this time, the vertical plate 21 and the movable plate 22 are moved outward along the notch 51, so that the rotating fan 24 moves outward to disperse the flowing water. Similarly, when the inclined plate 5 rotates in the direction close to the filter plate 2, the water flowing on the inclined plate 5 will fall on the filter plate 2 at a position closer to the fixed rod 3. At this time, the vertical plate 21 and the movable plate 22 are moved inward along the notch 51, so that the rotating fan 24 moves inward to disperse the flowing water. When the angle of the inclined plate 5 changes, the position of the rotating fan 24 also needs to change accordingly so that the rotating blades of the rotating fan 24 can contact the water when the rotating fan 24 rotates.

[0038] See also Figure 8-Figure 9 As shown, in the present embodiment, preferably, a second gear 26 is fixedly provided on the top of the other rotating wheel 23, and a second rack 27 is fixedly provided in the inclined plate 5 located in the notch 51, and the second gear 26 is meshed with the second rack 27 for transmission; during the movement of the movable plate 22 along the notch 51, the second gear 26 will mesh with the second rack 27 to realize the rotation of the second gear 26, and the rotation of the second gear 26 drives one of the rotating wheels 23 to rotate, thereby driving the other rotating wheel 23 and the rotating fan 24 to rotate through the belt 25, and this step can realize the rotation of the rotating fan 24 in the process of adjusting the position of the rotating fan 24, thereby dispersing the water flow.

[0039] See also Fig. 9As shown, in the present embodiment, preferably, a fixing plate 28 is fixedly provided in the notch 51, and the fixing plate 28 is located on one side of the vertical plate 21. A push rod 29 is movably provided through the center of the fixing plate 28, and one end of the push rod 29 is fixedly connected to the vertical plate 21, and a spring 30 is fixedly connected between the fixing plate 28 and the vertical plate 21; when it is necessary to adjust the position of the rotating fan 24, the position of the rotating fan 24 can be adjusted by moving the vertical plate 21 outward or inward along the notch 51, and when the vertical plate 21 is moved outward, the rotating fan 24 also moves outward, and the spring 30 is in a stretched state, and then the vertical plate 21 and the rotating fan 24 are driven to move inward to the initial position under the action of the spring 30 restoring the state.

[0040] See also Figure 8 As shown, in this embodiment, preferably, an arc plate 31 is fixedly provided on the outer side of the fixing rod 3, and the push rod 29 slides and fits with the arc plate 31 at one end away from the vertical plate 21; when the inclined plate 5 rotates along the fixing rod 3 in the direction away from the filter plate 2, the end of the push rod 29 moves along the position with a smaller arc of the arc plate 31 to a position with a larger arc. During the movement, the push rod 29 moves outward along the notch 51, and the spring 30 stretches, thereby driving the push plate to move outward to adjust the position of the rotating fan 24. During the movement, the rotating fan 24 will rotate with the cooperation of the second gear 26 and the second rack 27. Similarly, when When the inclined plate 5 rotates along the fixed rod 3 toward the direction approaching the filter plate 2, the end of the push rod 29 moves along the position with a larger curvature of the arc plate 31 to the position with a smaller curvature. Due to the loss of the abutment of the arc plate 31, the spring 30 will pull the vertical plate 21, the push rod 29 and the movable plate 22 inward during the recovery process. Since the return depends on the elastic potential energy of the spring 30, it is necessary to ensure that the energy stored in the spring 30 can overcome the resistance generated when the second gear 26 and the second rack 27 are engaged and the friction force generated when the vertical plate 21 moves in the slot 51. The fixed plate 28 provides support for the push rod 29.

[0042] The working principle of the present invention is: connect the breeding pond with one end of the water inlet pipe 4, let the tail water in the breeding pond flow into the filter barrel 1 through the water inlet pipe 4, the tail water flowing into the water inlet pipe 4 flows into the filter plate 2 below through multiple leakage holes 41, and the large particles mixed in the water body are removed by the filter plate 2. There is a certain height difference between the water inlet pipe 4 and the filter plate 2. The water flows through the leakage holes 41 and falls on the filter plate 2, which will cause a certain impact on the filter plate 2. Over time, the filter plate 2 will cause certain damage. Therefore, an inclined plate 5 is arranged below the water inlet pipe 4. The water flowing down through the leakage holes 41 first falls on the inclined plate 5, and then flows to the filter plate 2 through the inclined plate 5. The inclined plate 5 can play a buffering role and can protect the filter plate 2. Secondly, the water inlet pipe 4 is fixedly installed in the filter barrel, and the leakage holes 41 are fixedly installed in the filter barrel. 1 remains in position, and the area where the tail water flows down and contacts the filter plate 2 is also fixed, which will cause this area to bear all the tail water filtering work. After a long time, a large amount of impurities will be mixed in this area, and the filtering effect will be greatly reduced. Secondly, the rest of the filter plate 2 cannot contact the tail water, which will also affect the filtering efficiency of the tail water. The motor of the rotating shaft 15 is started, and the rotation of the rotating shaft 15 drives the rotating plate 14 to rotate. The rotation of the rotating plate 14 drives the limit block 13 to move up and down along the limit groove 121, thereby driving the swing rod 12 to swing back and forth. The reciprocating swing of the swing rod 12 drives the limit plate 11 and the fixed frame 9 to move back and forth horizontally. The reciprocating movement of the fixed frame 9 will drive the ring 7, the rotating block 8, the rotating rod 10, the disc 65 and the inclined plate 5 to move together The reciprocating movement of the inclined plate 5 can make the tail water fall on more areas of the filter plate 2. The reciprocating movement of the fixed frame 9 will also drive the rotating rod 10 and the first gear 19 to move reciprocally. During the movement of the first gear 19, it will mesh with the first rack 20 to realize the rotation of the first gear 19. The rotation of the first gear 19 drives the rotating rod 10 and the disc 65 to rotate. The rotation of the disc 65 drives the limit rod 64 to rotate. The rotation of the limit rod 64 drives the cylinder 63 to move back and forth along the positioning rod 62. The reciprocating movement of the cylinder 63 along the positioning rod 62 will drive the positioning rod 62 to swing back and forth up and down. The swing of the positioning rod 62 will drive the connecting rod 61 and the inclined plate 5 to swing back and forth up and down. The swing of the inclined plate 5 can adjust the angle of the inclined plate 5, thereby changing the tail water on the inclined plate 5 falling to the filter plate 2, when the inclined plate 5 rotates along the fixed rod 3 in the direction away from the filter plate 2, the end of the push rod 29 moves along the position of the smaller arc of the arc plate 31 to the position of the larger arc. During the movement, the push rod 29 moves outward along the notch 51, and the spring 30 is stretched, thereby driving the push plate to move outward to adjust the position of the rotating fan 24. During the movement, the rotating fan 24 will rotate under the cooperation of the second gear 26 and the second rack 27. Similarly, when the inclined plate 5 rotates along the fixed rod 3 in the direction close to the filter plate 2, the end of the push rod 29 moves along the position of the larger arc of the arc plate 31 to the position of the smaller arc. Due to the loss of the abutment of the arc plate 31, the spring 30 will pull the vertical plate 21, the push rod 29 and the movable plate 22 inward during the recovery process.The rotating fan 24 can always be in contact with the tail water flowing down from the inclined plate 5 to ensure the filtration quality.
