Description

TECHNICAL FIELD

[0001] The utility model relates to the aquaculture technical field more specifically, the utility model relates to a water quality improvement device for aquaculture. BACKGROUND

[0002] Aquaculture refers to the activity of cultivating aquatic organisms in a controllable environment, such as ponds, net cages and recirculating water systems, to meet food, economic or ecological needs. It is an important part of fisheries and alleviates the pressure of overfishing of wild fishery resources.

[0003] The culture water body is easily polluted by feed residues, excrement and the like, leading to accumulation of harmful substances such as ammonia nitrogen and nitrite, insufficient dissolved oxygen, and triggering diseases and even large-scale death. Water quality deterioration also accelerates the outbreak of algae (such as blue-green algae), further threatening biological health, so water quality improvement devices are needed to maintain water stability. The current water quality improvement device, for example, Chinese patent publication (announcement) No. CN220131943U "water quality improvement device for aquaculture", the device can be completely replaced on the shore when the activated carbon needs to be replaced, so that the user does not need to use the whole device from the water to replace it, and the improved water will be flushed into the culture water area at a high pressure, which can make the water surface of the culture water area turbulent, thereby oxygenating the water of the culture water area. However, high-pressure water flow mainly causes water surface disturbance, but oxygen dissolution mainly depends on gas-liquid contact area and contact time. Although the simple water surface turbulence can increase the contact area, if the water flow is too fast, oxygen is difficult to fully dissolve into the water, and most of the bubbles will quickly escape into the air, so the oxygen supply effect is not high, and it needs to be improved and optimized.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, this utility model provides a water quality improvement device for aquaculture, including a circulation tank 1 and a fixed frame 2. A drain pipe 4 is fixedly installed on the front side of the fixed frame 2, and a water pumping pipe 3 is fixedly installed on the rear side of the fixed frame 2. A water pump 11 is fixedly installed on the top of the circulation tank 1. The water pump 11 and the connecting pipe 17 are interconnected. The connecting pipe 17 and the water pumping pipe 3 are interconnected. A water pump 2 12 is fixedly installed on the bottom of the circulation tank 1. The water pump 2 12 and the connecting pipe 2 18 are interconnected. The connecting pipe 2 18 and the drain pipe 4 are interconnected.

[0026] Both the pumping pipe 3 and the drain pipe 4 are equipped with an aeration mechanism 5 on their outer walls. The aeration mechanism 5 includes a fixed shell 51 fixedly installed on the outer walls of the pumping pipe 3 and the drain pipe 4. A transmission blade 52 is rotatably installed inside the fixed shell 51. A float 53 is fixedly installed on the top of the fixed shell 51. A baffle 54 is fixedly installed on the inner wall of the float 53. A reciprocating screw 55 is rotatably installed inside the float 53. One end of the reciprocating screw 55 passes through the interior of the fixed shell 51 and is fixedly connected to the rotating shaft of the transmission blade 52. A piston plate 56 is movably installed inside the float 53. The piston plate 56 and the reciprocating screw 55 are threadedly connected. A counterweight 59 is fixedly installed on the bottom of the fixed shell 51. The float 53 and the counterweight 59 are interconnected through an exhaust pipe 58. A one-way exhaust valve 7 is installed inside the exhaust pipe 58. An air extraction pipe 57 is fixedly installed on the outer wall of the float 53. A one-way air inlet valve 6 is installed inside the air extraction pipe 57.

[0027] When the water quality needs to be improved, the staff first places the water suction pipe 3 and the drain pipe 4 in the aquaculture water area, then rotates the spiral pile 22, so that the bottom of the spiral pile 22 penetrates through the convex edge 21 and penetrates into the soil, and further fixes the fixing frame 2. At this time, due to the heavy weight of the counterweight 59, it can ensure that the water suction pipe 3 and the drain pipe 4 are immersed in the water, and the floating block 53 is hollow and light in weight, which can avoid the water suction pipe 3 and the drain pipe 4 sinking into the bottom of the water. Then the staff starts the water pump one 11 and the water pump two 12. The operation of the water pump one 11 can suck the water into the inside of the circulating box 1 through the aeration mechanism 5, and the operation of the water pump two 12 can discharge the improved water into the water through the drain pipe 4. When improving the water quality, the water flows in the inside of the water suction pipe 3 and the drain pipe 4, and further the transmission blade 52 is driven to rotate by the water flow, so as to rotate the reciprocating screw rod 55. The rotation of the reciprocating screw rod 55 drives the piston plate 56 which is sleeved with the reciprocating screw rod 55 to displace up and down. When the piston plate 56 displaces downward, the air in the floating block 53 pushes the plug two 71 downward, further makes the air pass through the one-way exhaust valve 7 and the exhaust pipe 58, and finally is sprayed from the bottom of the counterweight 59. The porous setting at the bottom of the counterweight 59 can discharge the air into the water and form dense bubbles, so as to ensure the contact area between the air and the water. When the piston plate 56 displaces upward, the plug two 71 is reset by the elastic potential energy of the spring two 73, so as to block the one-way exhaust valve 7, and the plug one 61 is pulled inward, so as to make the external air supplement into the inside of the floating block 53 through the air suction pipe 57 and the one-way air inlet valve 6. At this time, when the circulating box 1 improves the water quality, the aeration mechanism 5 can also supplement the nutrients in the water, so as to improve the healthy growth of aquatic products.

[0028] By continuously sucking the water into the inside of the circulating box 1 to improve the water quality, and then discharging the improved water into the water body through the drain pipe 4, compared with the traditional device, the device can also convert the kinetic energy generated by the water flow into the energy for the piston plate 56 to displace up and down when improving the water quality through the setting of the transmission blade 52 in the aeration mechanism 5. Further, the piston plate 56 continuously punches the external air into the counterweight 59, and finally sprays out through the exhaust hole at the bottom of the counterweight 59, so as to increase the contact area between the oxygen and the water and improve the oxygen content in the water.

[0029] Among them, the outer wall of the water suction pipe 3 and the drain pipe 4 is provided with a plurality of aeration mechanisms 5, and each group of aeration mechanisms 5 is staggered front and back.

One end of the dosing tank 15 and the atomizing nozzle 14 are in communication with each other.

[0036] When the water quality is improved, the water will enter from the top of the circulating box 1, and after being filtered by the filter assembly 13, it will be discharged through the bottom of the water pump two 12. When being filtered by the filter assembly 13, the staff can spray the nutrient solution in the dosing tank 15 through the atomizing nozzle 14 by the water pump in the dosing tank 15, so as to ensure the nutrients of the improved water body.

[0037] Through the setting of the filter assembly 13 in the circulating box 1, the water can automatically complete the filtration of impurities when circulating, avoiding the turbidity of the water body caused by feed and excrement. At the same time, the staff can add nutrient solution in the dosing tank 15 to supplement the nutrients of the water body, improve the growth efficiency of aquatic products, and the staff can also open the box door 16 to realize the cleaning of the filter assembly 13, which is convenient and fast. Compared with the traditional device, the device can also fix the fixing frame 2 through the setting of the spiral pile 22, so as to ensure the convenience of the staff to recycle.
