Description

Technical Field

[0001] The invention relates to the technical field of aquaculture boxes, and in particular to an aquaculture box pollution treatment device and a treatment method thereof. Background Art

[0002] Aquaculture boxes are indispensable tools in aquaculture, mainly used for the breeding of aquatic organisms such as fish, shrimp, crabs, etc. They can be placed in certain waters for fish farming. They are mostly set in lakes, rivers, reservoirs and other waters with certain water flow, fresh water quality and high dissolved oxygen content.

[0003] When the breeding boxes are placed in lakes for breeding, the fish feces will cause water pollution in the breeding boxes and the lake. When some aquaculture boxes are placed in lakes to breed fish, the feces produced during the growth of the fish are directly discharged into the lake, causing long-term water pollution in the lake. In addition, the fish feces produced in some aquaculture boxes are manually salvaged and discharged, which is inefficient. In addition, when discharging sewage, the fish in the breeding boxes need to be salvaged and transferred for processing of the feces. The fish cannot adapt to the new environment during the transfer process, which affects their growth.

[0021] The present invention provides a method for treating pollution in an aquaculture tank, which is applied to the above-mentioned device for treating pollution in an aquaculture tank, and comprises the following steps:

[0022] S1: When discharging sewage, the remote start motor starts working, and under the belt drive, the crankshaft and the spiral dragon are driven to rotate, and the fish feces that pass through the fish intercepting net and fall into the sewage trough are pushed toward the sewage outlet net until the feces are pushed through the sewage outlet net and enter the water tank;

[0023] S2: The fish excrement pushed into the inner surface of the water tank can be operated by remotely controlling the water pump, and the water on the inner surface of the water tank and the fish excrement can be pumped into the water pump pipe and then discharged from the drain pipe to carry out the sewage treatment of the fish excrement;

[0024] S3: During the sewage discharge process, the fish blocking net blocks the fish from entering the spiral auger, and only feces fall down, and the water inlet net is set between the sewage guide plate and the sewage trough to block the feces from being discharged from the bottom of the breeding box;

[0025] S4: During breeding, the crankshaft can be rotated to drive the connecting rod to move, so that the fish intercepting net and the intercepting plate can move up and down, and the plurality of fish driving plates can be driven to move up and down inside the breeding box to drive the fish to swim.

[0026] Beneficial effects of the present invention:

[0027] 1. The invention remotely controls the crankshaft to drive the spiral dragon to rotate and push the fish feces in the breeding box into the water tank, and then the feces are pumped out of the water tank to discharge the feces, so as to decontaminate the breeding box, and the sewage can be discharged without salvaging the fish school, which is convenient and saves trouble. In the process of crankshaft rotation, the fish intercepting net is driven to move up and down to be washed by water, so that the feces fall off and prevent the fish intercepting net from being attached to the fish intercepting net and causing blockage, which is beneficial to sewage discharge. In the process of the fish intercepting net moving up and down, the fish driving plate is driven to move on the inner surface of the breeding box, stirring the internal water flow, simulating the dynamic environment on the inner surface of the breeding box, driving the fish to swim, and promoting the growth of the fish school. It can not only discharge sewage, but also promote the movement and health of fish, so that the breeding box no longer has a single breeding function, and scientific fish breeding is achieved.

[0028] 2. After the fish food is stored in the food box, part of the fish food enters the inside of the distribution trough. At this time, the stepper motor is remotely controlled to drive the distribution plate to rotate at a low speed, and the fish food in the distribution trough is sent to the upper end of the feeding trough. Under the action of gravity, the fish food slowly flows downward inside the feeding trough. The wavy structure of the feeding trough can make the fish food flow more slowly and prevent the fish food from rushing down directly to the water inside the breeding box and causing huge splashes to scare the fish. Then the fish food flows out from the lower end of the feeding trough into the breeding box to supplement the fish food and provide for the growth of the fish, so as to achieve automatic feeding, fixed-point and quantitative feeding, and provide convenience for people to breed fish.

[0029] 3. When the liquid level inside the breeding box and water tank rises with the liquid level of the lake, the floating box floats up and touches the sliding block, driving the water inlet trough in the round plug to rotate. At this time, the nutrient additives flow from the water inlet pipe, water inlet trough, and drainage trough and then enter the water tank and breeding box for fish to inhale and absorb, promoting fish growth. In the process of breeding fish in the lake breeding box, with the dynamic changes of the lake liquid level, the nutrient additives in the storage box are intermittently sent to the breeding box, providing nutrients for the fish growth intermittently to meet their needs, and realizing humane breeding.

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.

[0043] Embodiment 1

[0044] See also Figure 1 - Fig.10 As shown, a pollution treatment device for an aquaculture box comprises a culture box 1, a fixing frame 101 is fixed on one side of the culture box 1, and the fixing frame 101 is used to be installed on a prefabricated cement column at a fish farming position in a lake, so that the culture box 1 enters the lake, and the water in the lake enters from the bottom of the culture box 1, and the culture box 1 is installed for fish farming; a decontamination mechanism 8, a decontamination mechanism 8 is installed inside the culture box 1, and the decontamination mechanism 8 comprises a decontamination guide plate 84, two decontamination guide plates 84 are arranged obliquely and separated at the lower ends, and the lower ends of the two decontamination guide plates 84 are both vertically slidably provided with an interception plate 810 A fish intercepting net 86 with an arched structure is fixed between the two intercepting plates 810, a sewage trough 87 is fixed to the inner wall of the lower end of the breeding box 1, and a spiral dragon 88 is rotatably arranged inside the upper end of the sewage trough 87. A crankshaft 81 is fixed to one end of the spiral dragon 88, and the axis of the crankshaft 81 is rotatably connected to one side of the breeding box 1. A water inlet 102 is opened on the other side of the breeding box 1, and a sewage outlet net 85 located on one side of the spiral dragon 88 is fixed to the inner wall of the water inlet 102. The lower surfaces of the two intercepting plates 810 are fixed with an arc-shaped water inlet net on the side wall of the sewage trough 87. 89, a motor 83 is fixed to the fixing frame 101, and a belt 82 is connected to the output shaft of the motor 83 and one end of the crankshaft 81; during breeding, the breeding box 1 is installed in the water of the lake, and water enters from the water inlet net 89 at the bottom of the breeding box 1 and then enters the inside of the breeding box 1 through the fish intercepting net 86, and the fish are bred by the water of the lake. When sewage is discharged, the feces of the fish pass through the sewage guide plate 84 downward through the fish intercepting net 86 (which can be a wire mesh, fish cannot pass through, but feces can pass through) and enter the sewage trough 87. When a lot of feces accumulates, personnel uniformly pass through the remote The motor 83 is controlled by a program to work, driving the crankshaft 81 to rotate, so that the spiral dragon 88 rotates, pushing the fish feces in the sewage trough 87 to the sewage outlet net 85, until it passes through the sewage outlet net 85 and enters the water tank 51 and is then pumped out, so as to treat the pollution in the breeding box 1, and prevent the feces from being directly discharged into the lake and causing pollution. In addition, during the sewage discharge process, the fish intercepting net 86 intercepts the fish and prevents them from entering the sewage trough 87, so that sewage can be discharged without salvaging the fish. Moreover, the feces can be discharged remotely without the need for personnel to be on duty for a long time, which provides convenience for the sewage discharge of farmed fish and breeding boxes.

[0045] Fish-driving mechanism 9, the fish-blocking net 86 is equipped with a fish-driving mechanism 9; the light-filling mechanism 2, the bottom of the breeding box 1 is open, and the light-filling mechanism 2 is installed on the upper end of the back of the breeding box 1; the automatic feeding mechanism 3, the automatic feeding mechanism 3 is installed on the upper end of the light-filling mechanism 2; the nourishing mechanism 5, the nourishing mechanism 5 is installed on one side of the breeding box 1; the material dividing mechanism 7, the automatic feeding mechanism 3 is installed with the material dividing mechanism 7; the discharge mechanism 6, the discharge mechanism 6 for drainage and defecation is installed on the upper end of the nourishing mechanism 5.

[0046] Embodiment 2

[0047] As an example, in order to simulate the dynamic environment of fish growth, see Figure 4 , Figure 5 The fish-driving mechanism 9 includes a fish-driving plate 91. A plurality of fish-driving plates 91 are fixed on both sides of the fish-blocking net 86. The middle part of the fish-driving plate 91 is in an S-shaped structure to increase the cross-section and stir the water flow. The crankshaft 81 is rotatably connected to a connecting rod 93. The upper end of the connecting rod 93 is rotatably connected to a rotating rod 94. One end of the rotating rod 94 is rotatably connected to a fixed cylinder 92. The fixed cylinder 92 is fixedly connected to the lower surface of the fish-blocking net 86. The fish-blocking net 86 is used to intercept fish from entering the sewage trough 87 and for fish feces to pass through and fall. When the crankshaft 81 is driven by the motor 83 to rotate and drive the spiral dragon 88 to rotate and discharge feces, the crankshaft 81 rotates to drive the connecting rod 93 to move. Under the action of the connecting rod 93, the rotating rod 94 and the fixed cylinder 92 are driven. The fish blocking net 86 and the two intercepting plates 810 move together, so that the fish blocking net 86 and the two intercepting plates 810 move up and down (move between the lower ends of the two sewage guide plates 84). The up and down movement of the fish blocking net 86 can be repeatedly impacted by the water in the breeding box 1, so that the fish feces fall and are pushed away by the spiral auger. Furthermore, the up and down movement of the fish blocking net 86 drives the multiple fish driving plates 91 to move up and down on the surface of the breeding box 1, stirs the internal water flow, drives the fish to swim, and simulates a dynamic environment. Appropriate driving can stimulate the physiological response of fish and increase the vitality of fish. Fish need to swim continuously to avoid or adapt to the new environment, which helps to exercise the muscles of fish, improve physical fitness, and enhance the immunity of fish, so that they can better resist the invasion of diseases and parasites, and scientific breeding.

[0048] Specifically, in order to facilitate the growth of fish, the fill light mechanism 2 includes a bracket 22, which is fixed to the upper end of the breeding box 1. A horizontally arranged flat plate 21 is fixed to the upper end of the bracket 22. Two fill lights 23 are installed on the surface of the flat plate 21. The upper end of the feeding square tube 34 is vertically slidably connected to the flat plate 21.

[0049] As an example, see Figure 1 , Fig. 9The automatic feeding mechanism 3 includes a food box 32, which is fixed on the upper surface of the flat plate 21. A feeding tube 31 is fixedly passed through the upper end of the food box 32, and a feeding square tube 34 passing through the flat plate 21 is fixedly connected to the lower end of the food box 32. The upper end of the feeding square tube 34 is open, and a feeding trough 36 is provided inside the feeding square tube 34. The feeding trough 36 has a wavy structure. An exhaust pipe 35 with an arc-shaped structure is fixed to one side of the feeding square tube 34. The lower end of the exhaust pipe 35 extends into the interior of the breeding box 1. An exhaust hole 33 is obliquely arranged near the lower end of the inner wall of the feeding square tube 34. The two ends of the exhaust hole 33 are respectively connected to the feeding trough 36 and the exhaust pipe 35. The distributing mechanism 7 includes a distributing plate 72, which is rotatably connected between the food box 32 and the feeding square tube 34. A stepping motor 7 is fixed to the outside of the food box 32. 1. The output shaft of the stepper motor 71 is fixedly connected to the center of the distribution plate 72, and three distribution troughs 73 are opened on the outer side of the distribution plate 72; after the fish food is stored in the food box 32, a part of the fish food enters the inside of the distribution trough 73, and at this time, the stepper motor 71 is remotely controlled to work, driving the distribution plate 72 to rotate at a low speed, and the fish food in the distribution trough 73 is sent to the upper end of the feeding trough 36, and the fish food slowly flows downward inside the feeding trough 36 under the action of gravity. The wavy structure of the feeding trough 36 can make the fish food flow more slowly, and prevent the fish food from rushing down directly to the water inside the breeding box 1 and causing huge splashes to scare the fish, and then the fish food flows out from the lower end of the feeding trough 36 into the breeding box 1 to supplement the fish with food for the growth of the fish, so as to achieve automatic feeding, fixed-point and quantitative feeding, and provide convenience for personnel to breed fish.

[0050] Embodiment 3

[0051] Based on the first embodiment, refer to Fig. 9 and Fig.10Furthermore, in order to buffer the descent of fish food and reduce the splashes caused by the impact on the liquid surface, and to avoid scaring the fish, a rubber stopper 41 for buffering the falling fish food is arranged below the feeding trough 36 to further decelerate the fish food. Specifically, a buffering mechanism 4 is installed at the lower end of the feeding square tube 34, and the buffering mechanism 4 includes a counterweight plate 42. A support seat 43 is fixed to the lower end of the feeding square tube 34, and the upper end of the counterweight plate 42 is rotatably connected to the support seat 43. A rubber stopper 41 with an arc structure is fixed to the other end of the counterweight plate 42. The rubber stopper 41 is located below the feeding trough 36. An adjusting screw 45 is threadedly connected to the lower end of the feeding square tube 34, and a slider 44 is rotatably connected to the right end of the adjusting screw 45. A slide groove 46 is provided at the lower end of the feeding square tube 34, and the slider 44 is horizontally slidably connected to the inside of the slide groove 46. The cable 47 passes through the chute 46 and extends out of the lower end of the feeding trough 36. The lower end of the cable 47 is fixedly connected to the upper surface of the counterweight plate 42. During feeding, when the fish food is fed into the feeding trough 36 and flows downward until it flows out, the fish food falls on the upper surface of the rubber stopper 41, and is buffered and decelerated again by the rubber stopper 41. Then, the fish food falls from the rubber stopper 41 tilted downward into the breeding box 1. Under the conditions of double deceleration of the feeding trough 36 and the rubber stopper 41, the fish food falls into the breeding box 1 at a relatively low speed, reducing the splashing water and effectively preventing the fish from being frightened. By rotating the adjusting screw 45, the slider 44 slides left and right, the cable 47 pulls or releases the counterweight plate 42, and the rubber stopper 41 is rotated clockwise and counterclockwise to adjust the angle, so as to control the buffering strength of the falling fish food and the position of the fish food falling into the breeding box 1, so that feeding is diversified and available.

[0052] Specifically, for fish farming and growth, see Figure 2-Figure 3 , Figure 8The replenishment mechanism includes a water tank 51, which is fixed to the right outer surface of the breeding box 1. An L-shaped water inlet pipe 52 is fixed to the right side of the water tank 51, and a storage box 515 is fixed to the upper end of the water inlet pipe 52. A cylinder 53 is fixedly connected to the left end of the water inlet pipe 52. A round plug 512 is rotatably connected inside the cylinder 53. A rotating shaft 55 is fixed to the center of the round plug 512. The rotating shaft 55 is rotatably connected to the center of the cylinder 53. A drainage groove 56 is provided at the lower end of the cylinder 53. A water inlet groove 54 is provided inside the cylinder 53. The water inlet groove 54 is an L-shaped structure. A movable opening 57 is provided on one side of the cylinder 53. The movable opening 57 is rotatably connected to a lever 58 fixed to the round plug 512. The end of the lever 58 is rotatably connected to a connecting rod 59. A slide rail 511 is installed on the outer side of the breeding box 1. The slide rail 511 is vertically slidably connected to a sliding block 510. The connecting rod The lower end of 59 is rotatably connected to one side of the sliding block 510, a support rod 513 is fixed to the bottom end of the water tank 51, and the support rod 513 is vertically slidably connected to the floating box 514; the storage box 515 stores nutrient additives that promote the growth of fish (such as vitamin C and vitamin E. The addition of vitamin C to fish feed can significantly increase the daily weight gain and feed conversion rate of fish, while enhancing the immunity of fish, while vitamin E helps to improve the growth rate and antioxidant capacity of fish). The water inlet 102 of the water tank 51 is connected to the breeding box 1, and the liquid levels of the two are flush after water is taken in. When the water level of the lake changes and rises, the liquid levels of the breeding box 1 and the inner surface of the water tank 51 also rise, causing the floating box 514 to float up and touch the sliding block 510, pushing the sliding block 510 upward, and under the action of the connecting rod 59, driving the round plug 512 and the water inlet trough 54 to rotate clockwise (see Figure 8 ), when the rotating end of the water inlet trough 54 is connected with the left end of the water inlet pipe 52 and the drainage trough 56 respectively, the nutrient additives on the surface of the storage box flow from the water inlet pipe 52, the water inlet trough 54, and the drainage trough 56 and then enter the water tank 51, until they pass through the sewage outlet net 85 from the water outlet 102 and enter the breeding box 1, for the fish to inhale and absorb, thereby promoting the growth of the fish. When the liquid level of the lake drops, the liquid level of the water tank 51 drops, the floating box 514 moves down, and the sliding block 510 moves down under the action of gravity, pulling the round plug 512 to rotate counterclockwise to reset, blocking the water inlet pipe 52, and the nutrient additives no longer flow into the water tank 51, thereby preventing the breeding box 1 from breeding fish in the lake. With the dynamic changes of the lake liquid level, the nutrient additives in the storage box are intermittently sent into the breeding box 1, providing nutrients for the growth of the fish intermittently to meet their needs, and realizing humanized breeding.

[0053] Specifically, the discharge mechanism 6 includes a water pump 62, which is fixed at the upper end of the water tank 51. The inlet of the water pump 62 is connected to a curved pipe 61, which extends into the interior of the water tank 51. A pumping pipe 64 located inside the water tank 51 is fixed at one end of the curved pipe 61. The lower end of the pumping pipe 64 does not contact the inner wall of the bottom end of the water tank 51, and the discharge port of the water pump 62 is connected to a drain pipe 63. When discharging sewage, personnel remotely start the water pump 62 to pump water, and the water inside the water tank 51 is pumped into the curved pipe 61 from the pumping pipe 64, and then discharged from the drain pipe 63. The drain pipe 63 is externally connected to a wastewater treatment tank (installed at the breeding location).

[0054] The present invention provides a method for treating pollution in an aquaculture tank, which is applied to the above-mentioned device for treating pollution in an aquaculture tank, and comprises the following steps:

[0055] S1: When discharging sewage, the remote start motor starts working, and under the belt drive, the crankshaft and the spiral dragon are driven to rotate, and the fish feces that pass through the fish intercepting net and fall into the sewage trough are pushed toward the sewage outlet net until the feces are pushed through the sewage outlet net and enter the water tank;

[0056] S2: The fish excrement pushed into the inner surface of the water tank can be operated by remotely controlling the water pump, and the water on the inner surface of the water tank and the fish excrement can be pumped into the water pump pipe and then discharged from the drain pipe to carry out the sewage treatment of the fish excrement;

[0059] Working principle: First, the breeding box 1 is placed in the lake, and the fish are bred with the water from the lake. The feces of the fish pass through the sewage guide plate 84 downward through the fish intercepting net 86 and enter the sewage trough 87. When a lot of feces accumulates, the personnel uniformly remotely control the motor 83 to drive the crankshaft 81 to rotate, so that the spiral dragon 88 rotates, and the fish feces in the sewage trough 87 are pushed toward the sewage outlet net 85 until they pass through the sewage outlet net 85 into the water tank 51 and are then pumped out, so as to treat the pollution in the breeding box 1 and prevent the feces from being directly discharged into the lake and causing pollution. In the sewage discharge process, the fish intercepting net 86 intercepts the fish and prevents them from entering the sewage trough 87, so the sewage can be discharged without salvaging the fish, and the feces can be discharged remotely without the need for Personnel are on duty for a long time to provide convenience for the discharge of sewage from farmed fish and breeding boxes. When the crankshaft 81 rotates through the motor 83 to drive the spiral dragon 88 to rotate and discharge feces, the rotation of the crankshaft 81 drives the connecting rod 93 to move. Under the action of the connecting rod 93, the rotating rod and the fixed cylinder 92 are driven to move together, so that the fish blocking net 86 and the two intercepting plates 810 move up and down. The up and down movement of the fish blocking net 86 can be repeatedly impacted by the water in the breeding box 1, so that the fish feces fall and are pushed away by the spiral dragon. Furthermore, the up and down movement of the fish blocking net 86 drives multiple fish driving plates 91 to move up and down on the inner surface of the breeding box 1, stirring the internal water flow, driving the fish to swim, simulating a dynamic environment, and promoting fish growth.
