Description

[0002] Importance of Mariculture Tailwater Treatment Mariculture is an important economic industry, but it is also accompanied by a large amount of wastewater discharge. These wastewaters contain a large amount of pollutants such as plankton, organic matter and suspended particles. If they are not treated and directly discharged into the ocean, they will cause serious pollution and damage to the marine ecosystem. Therefore, mariculture tailwater treatment is very necessary.

[0003] Seawater aquaculture tail water can be treated using an electric flotation treatment device. The flotation machine is a water treatment equipment based on the principle of gas-liquid mixing. It injects air into the water to form bubbles, which floats solid particles, oils and other substances suspended in the water, thereby achieving the purpose of purifying the water quality.

[0004] In existing electrical flotation treatment devices, a scraper plate is usually used to clean the scum floating on the sewage surface into a scum tank. However, impurities such as fine scum are easily adhered to the scraper plate, making it difficult to clean. As the scraper plate continuously cleans the scum on the sewage surface, the scum on the scraper plate gradually accumulates. The accumulated scum adheres to the surface of the scraper plate, which affects the scraping effect, thereby reducing the sewage treatment efficiency. Summary of the invention

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] like Figures 1 to 3As shown, an electric flotation treatment device for treating tail water of marine aquaculture comprises an air flotation tank 1, a bubble generating mechanism and a scum collecting mechanism 2. A sewage inlet 3 is provided on one side of the outer wall of the air flotation tank 1 near the bottom. A decontamination tank 4 is formed on one side of the air flotation tank near the sewage inlet 3. The scum collecting mechanism 2 is arranged on the side of the decontamination tank 4 away from the sewage inlet 3. The scum collecting mechanism 2 comprises a scum tank 21, a plurality of scraping plates 22 and a driving component 23. The driving component 23 drives the plurality of scraping plates 22 to scrape the scum on the water surface into the scum tank 21 in turn. A water collecting chamber 10 is provided on the side of the scum tank 21 away from the air flotation tank 1. The water collecting chamber 10 is provided inside the water collecting chamber 10. A water passage 14 is provided on the wall and is connected to the decontamination tank 4. A clean water outflow outlet 5 is provided on the surface of the flotation tank 1 for discharging clean water in the water collecting chamber 10. A cleaning plate assembly 6 is provided on the side of the scraper plate 22 close to the scum tank 21. The cleaning plate assembly 6 is used to clean the scum (impurities) remaining on the scraper plate 22. A moving assembly 7 is connected to one side of the cleaning plate assembly 6. The cleaning plate assembly 6 includes cleaning plates 61 arranged on the upper and lower sides of the scraper plate 22 and a driving assembly 8 connected to one side of the cleaning plate 61. The driving assembly 8 drives the cleaning plate 61 to contact the surface of the scraper plate 22, and the moving assembly 7 drives the cleaning plate 61 to scrape off the scum remaining on the surface of the scraper plate 22.

[0031] Specifically, a partition is provided in the decontamination tank 4 on one side close to the sewage inlet 3, and the partition divides the decontamination tank 4 into a first tank and a second tank. The sewage inlet 3 is connected to the first tank, and the bubble generating end of the bubble generating mechanism extends into the first tank. The pretreated seawater aquaculture tail water (sewage) flows from the sewage inlet 3 into the first tank, and the bubble generating mechanism generates sewage in the first tank. The tiny bubbles generated by the bubble generating mechanism will carry away the suspended matter, plankton, colloid and other impurities in the water when they rise, so that the impurities float on the water surface. The rising sewage flows into the second tank after passing over the partition, until the liquid level of the sewage rises to the edge of the scum tank 21, and the driving component 1 23 drives the multiple scraping plates 22 to scrape the scum into the scum tank 21.

[0032] Furthermore, the driving assembly 23 is symmetrically arranged, and the driving assembly 23 includes two sets of synchronous wheels 231 and a synchronous belt 232. The two sets of synchronous wheels 231 are rotatably connected to the inner wall of the flotation tank 1, and the synchronous belt 232 is engaged with the two sets of synchronous wheels 231. One side of one set of synchronous wheels 231 is connected to a driving member 9, and the driving member 9 drives the synchronous wheels 231 to rotate, and multiple sets of scraper plates 22 are equally connected to the surface of the synchronous belt 232.

[0033] Furthermore, the driving member 9 includes a water wheel 91 and a transmission assembly 92. A water flow chamber 11 is provided below the water collecting chamber 10. A water outlet 12 is provided at the bottom of the water collecting chamber 10 and is connected to the water flow chamber 11. The clean water outflow port 5 is connected to the water flow chamber 11. The water wheel 91 is located below the water outlet 12 and is rotatably connected to the inner wall of the water flow chamber 11 through a rotating shaft 13. The water in the water collecting chamber 10 flows out from the water outlet 12, thereby driving the water wheel 91 to rotate.

[0034] Furthermore, valves are provided at the water outlet 12 and at one end of the water passage 14 close to the decontamination tank 4 .

[0035] It should be noted that the valve is an electrically controlled valve.

[0036] It should be further explained that when the liquid level of the sewage in the second tank rises to the edge of the scum tank 21, the electrically controlled valve at the water passage 14 is opened, and the clean water at the bottom flows into the water collecting chamber 10 through the water passage 14, until the liquid level of the sewage in the second tank rises to the edge of the scum tank 21 again, the water outlet 12 in the water collecting chamber 10 is opened, and the clean water flowing out of the water outlet 12 drives the water wheel 91 to rotate.

[0037] Specifically, the water outlet 12 is located above the water wheel 91 and away from the scum tank 21. Therefore, when the water in the water collecting chamber 10 flows out from the water outlet 12, the water wheel 91 will always rotate in one direction, thereby driving the missing gear 924 to rotate through the rotating shaft 13.

[0038] like Figure 4 and Figure 5 As shown, the transmission assembly 92 includes two sets of synchronous wheels 921, synchronous belt 922, fan-shaped block 923 and missing circular plate 925. The synchronous belt 922 is meshed with the two sets of synchronous wheels 921. The end of the rotating shaft 13 close to the clean water outlet 5 extends to the outside of the flotation tank 1 and is connected with a missing gear 924 and a fan-shaped block 923. The surface of the flotation tank 1 is rotatably connected with a driven gear 926, which is meshed with the missing gear 924. The driven gear 926 is coaxially connected with a set of synchronous wheels 921 and a missing circular plate 925. The missing circular plate 925 and the fan-shaped block 923 cooperate with each other to limit the rotation of the driven gear 926.

[0039] It should be noted that the missing circular plate 925 is an incomplete circular plate (i.e., an arc-shaped notch is opened on the complete circular plate). When the missing gear 1 924 cannot drive the driven gear 1 926 to rotate, the arc surface of the fan-shaped block 923 away from the rotating shaft 13 will contact the arc surface at the notch of the missing circular plate 925, thereby limiting the rotation of the synchronous wheel 2 921. Each time the synchronous wheel 2 921 stops rotating, one set of scraper plates 22 will be located above the scum trough 21 and in a horizontal state.

[0040] like Figure 6 and Fig.10 The partial structure shown in the figure, the driving component 8 includes a shell 81, a rotating shaft 82, a push plate 83, a triangular plate 84 and a driving member 85. The moving component 7 is connected to the surface of the shell 81. The middle part of the slag cleaning plate 61 is connected to the inner wall of the shell 81 through the rotating shaft 82. The end of the slag cleaning plate 61 away from the scraper plate 22 is rotatably connected with a roller 86. The push plate 83 is slidably connected to the inner wall of the shell 81. The end of the push plate 83 close to the slag cleaning plate 61 is provided with two inclined surfaces corresponding to the slag cleaning plate 61. The roller 86 rolls along the inclined surface. The triangular plate 84 A corner is rotatably connected to the inner wall of the shell 81, and a slide groove 87 is provided at a corner of the surface of the triangular plate 84 near the slag cleaning plate 61. A slider 88 is connected to the corner of the side of the surface of the triangular plate 84 near the push plate 83. A slide groove 89 is provided on the surface of the push plate 83. A slider 810 is connected to the surface of the slag cleaning plate 61. The slider 810 slides along the inside of the slide groove 87, and the slider 88 slides along the inside of the slide groove 89. The push plate 83 is connected to the driving end of the driving member 85, and the driving member 85 is connected to the inner wall of the shell 81.

[0041] It should be noted that the second driving member 85 is any mechanical structure capable of linear motion, and specifically, may be an electric push rod, a hydraulic rod, etc.

[0042] In actual use, when one group of scraper plates 22 is located above the scum groove 21 and is in a horizontal state, the moving component 7 will drive the scum cleaning plate 61 to move in the direction of the scraper plate 22, so that the scraper plate 22 is located in the middle of the two groups of scraper plates 61, and then the driving member 2 85 is started to push the push plate 83 to slide along the inner wall of the shell 81. Due to the two inclined surfaces set on the push plate 83, the two groups of scraper plates 61 will be driven to rotate along the rotating shaft 82, thereby contacting the upper and lower surfaces of the scraper plates 22 respectively. At this time, the driving member 2 85 is started again to make the scraper plate 61 scrape off the scum remaining on the surface of the scraper plate 22.

[0043] It should be noted that the coordinated arrangement of the triangular plate 84, the first slide groove 87, the first slider 810, the second slide groove 89 and the second slider 88 enables the push plate 83 to drive the cleaning plate 61 to rotate and restore it to its original position when it moves away from the scraping plate 22.

[0044] like Figure 3 as well as Figures 7 to 9The partial structure shown, the moving assembly 7 includes a disc 71, a missing gear 2 72, two sets of synchronous wheels 3 73, a synchronous belt 3 74, a missing gear 3 75, a sleeve frame 76, a stopper 77 and a stopper column 78. The disc 71 is located outside the flotation tank 1 and is connected to the surface of the rotating shaft 13 away from the clean water outlet 5. A tooth groove is provided on the disc 71. The missing gear 2 72 is rotatably connected to the surface of the flotation tank 1. The missing gear 2 72 is meshed with the tooth groove. The stopper 77 is connected to the surface of the missing gear 2 72. The stopper column 78 is connected to the surface of the disc 71. A set of the synchronous wheels 3 73 and The missing gear 2 72 is coaxially connected, and a slide groove is provided at a position near the upper side of the flotation pool 1. The sleeve frame 76 is slidably connected in the slide groove and fixedly connected to the surface of the shell 81. The synchronous belt 3 74 is meshed with two sets of synchronous wheels 3 73. The missing gear 3 75 is coaxially connected with the synchronous wheel 3 73 away from the disc 71. The inner walls of the sleeve frame 76 on the upper and lower sides are connected with racks 79, and the two sets of racks 79 are meshed with the missing gear 3 75. The surface of the flotation pool 1 is connected with a mounting plate 710 at a position corresponding to the slide groove, and the synchronous wheel 3 73 away from the disc 71 is rotatably connected to the surface of the mounting plate 710.

[0045] In actual use, when the synchronous wheel 2 921 stops rotating, the disc 71 will drive the missing gear 2 72 to rotate, and further drive the two sets of synchronous wheels 3 73 and the synchronous belt 3 74 to rotate. Due to the coordinated arrangement of the missing gear 3 75, the sleeve frame 76 and the rack 79, the shell 81 will reciprocate.

[0046] It should be noted that the teeth on both sides of the toothless part of the missing gear 2 72 can clamp the arc-shaped edge of the disk 71, so that the missing gear 2 72 can move intermittently, that is, the missing gear 2 72 can rotate during the time when the synchronous wheel 2 921 stops rotating, and one rotation of the disk 71 can drive the missing gear 2 72 to rotate one circle, and one rotation of the missing gear 2 72 can drive the shell 81 to perform a reciprocating motion.

[0047] It should be noted that when the teeth on both sides of the toothed portion of the missing gear 2 72 are stuck to the arc-shaped edge of the disc 71, the rotation of the disc 71 can limit the rotation of the missing gear 2 72. When the stop column 78 moves the stop block 77, it will drive the missing gear 2 72 to rotate, so that the tooth groove engages with the missing gear 2 72, thereby driving the missing gear 2 72 to rotate.

[0048] like Fig.11 In the partial structure shown, a knocking assembly 15 is arranged inside the shell 81 for knocking the slag cleaning plate 61 so as to knock the slag on the slag cleaning plate 61 into the slag groove 21.

[0049] Furthermore, the knocking assembly 15 includes a corrugated plate 151, a connecting plate 152, a spring 153, a movable plate 154, a movable plate 2 155 and a knocking rod 156. The corrugated plate 151 is arranged between the two groups of slag cleaning plates 61 and penetrates the push plate 83 and is fixedly connected to the inner wall of the shell 81. The connecting plate 152 is connected to the corresponding surfaces of the two groups of slag cleaning plates 61. The position of the slag cleaning plate 61 is arranged at one end of the slag cleaning plate 61 close to the scraping plate 22. The cross-section of the connecting plate 152 is "U"-shaped. A knocking rod 156 is pierced through the surface of the connecting plate 152, and the surface of the knocking rod 156 is located inside the connecting plate 152 and is connected to the movable plate 154, and the surface of the knocking rod 156 is located outside the connecting plate 152 and is connected to the movable plate 2 155, one end of the spring 153 is connected to the surface of the connecting plate 152, and the other end of the spring 153 is connected to the surface of the movable plate 2 155, and the end of the knocking rod 156 away from the slag cleaning plate 61 moves along the surface of the corrugated plate 151.

[0050] It should be noted that the slag cleaning plate 61 turns at the rotating shaft 82, and the slag cleaning plate 61 is located on the side of the rotating shaft 82 away from the scraping plate 22 and forms a frame. When the slag cleaning plate 61 scrapes off the slag on the scraping plate 22 and moves in the direction away from the scraping plate 22, the driving member 2 85 will be started only after the slag cleaning plate 61 is completely away from the scraping plate 22, so that the two groups of slag cleaning plates 61 are close to The ends of the scraping plates 22 are moved away from each other, and then the knocking rod 156 slides along the surface of the corrugated plate 151, and the knocking rod 156 cooperates with the spring 153, the connecting plate 152, the movable plate 154 and the movable plate 2 155 to knock on the surface of the slag cleaning plate 61 to vibrate it, so that the slag remaining on the surface of the slag cleaning plate 61 falls into the slag groove 21.

[0051] It should be further explained that the surfaces of the upper and lower sides of the corrugated plate 151 are wavy, and the end of the knocking rod 156 close to the corrugated plate 151 is curved, so that it can slide along the surface of the corrugated plate 151.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
