DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The aquaculture water recycling and reuse treatment device disclosed in the present invention is mainly used in the existing aquaculture water recycling and reuse treatment device. During use, after the circulating water is filtered through the arc screen, a large amount of waste residue remains on the arc screen. The accumulation of the waste residue affects the water filtration efficiency. At the same time, part of the waste residue will clog the filter holes on the arc screen. The manual cleaning effect is poor. Only part of the waste residue accumulated on the arc screen can be collected, and the waste residue that clogs the screen holes on the arc screen cannot be collected and processed, thereby reducing the water circulation treatment efficiency and effect.

[0033] Reference Figure 1-Figure 11A water recycling and treatment device for aquaculture includes a filter tank 1 and a sterilization tank 7. A cleaning mechanism 2 is arranged inside the filter tank 1, and the cleaning mechanism 2 includes an intermediate platform 202. The intermediate platform 202 is fixedly connected to the inner walls on both sides of the filter tank 1 near the top. Rotation grooves are provided on both sides of the intermediate platform 202. The interiors of the two rotation grooves are connected to a deflection shaft 11 through a bearing. The outer walls of the two deflection shafts 11 are fixedly connected to an arc screen 8. The two arc screens 8 are distributed in an inner eight-shaped manner. The bottoms of the two arc screens 8 are fixedly connected to a telescopic sealing belt 221. The bottoms of the telescopic sealing belt 221 It is fixedly connected to the inner wall of the filter tank 1 below the arc screen 8, the outer wall of the filter tank 1 at the bottom ends of the two arc screens 8 are provided with waste discharge holes, and the filter tank 1 is fixedly connected with a hydraulic cylinder 203 at an equal distance above the two waste discharge holes, the output ends of the multiple hydraulic cylinders 203 on one side are fixedly connected with the same blocking door panel 201, the blocking door panel 201 is fitted with the outer wall of the filter tank 1 at the waste discharge hole, the side of the blocking door panel 201 facing the inside of the filter tank 1 is provided with a groove 220, and the arc screen 8 is fixedly connected with a matching clamping frame 219 at the groove 220.

[0034] In a specific application scenario, when the water circulation is in the intermittent stage, start the air compressor 213, adjust the hydraulic cylinder 212 to drive the limiting slider 207 to move back and forth, start the drive motor 217, and drive the motor 217 to drive the cleaning fine bristles 215 to brush the sieve holes of the arc screen 8. During the brushing process, compressed gas is ejected from each directional air needle 218, thereby pushing the cleaning fine bristles 215 that rotate to the sieve holes of the arc screen 8, and pushing part of the cleaning fine bristles 215 into the sieve holes, thereby improving the cleaning effect of the waste residue blocked inside the sieve holes. At the same time, the impact of the gas has a further effect of removing the waste residue blocked in the sieve holes. The two cooperate to achieve efficient cleaning of the sieve holes of the arc screen 8.

[0035] Specifically, during the cleaning process of the arc screen 8, the gas ejected from each directional air needle 218 has a pushing effect on the waste slag accumulated on the arc screen 8, accelerating the flow of the waste slag from the top of the arc screen 8 to the bottom, and then gradually exporting it. At the same time, during the cleaning process of the arc screen 8, the hydraulic cylinder 203 is adjusted to drive the blocking door panel 201 to move upward, so that the clamping frame 219 is separated from the cutting groove 220, and the connecting spring rod 208 in a compressed state drives the arc screen 8 to be in a state of vibration, further accelerating the falling of the waste slag, quickly exporting it, and improving the waste slag cleaning effect.

[0036] It should be noted that when the connecting spring rod 208 is reset and drives the arc screen 8 to be in an oscillating state, the waste residue blocked in the sieve holes of the arc screen 8 in the oscillating state is more easily separated from the sieve holes under the impact of the gas and the push of the cleaning fine bristles 215, further improving the waste residue cleaning effect in the sieve holes.

[0038] Reference Figure 1 , Fig.10 and Fig.11 In a preferred embodiment, the filter tank 1 is provided with a circulation diversion mechanism 3 above the two arc-shaped screens 8, and the circulation diversion mechanism 3 includes a diversion chamber 301, and the top of the diversion chamber 301 is fixedly connected to two mounting frames 4, and the two mounting frames 4 are respectively fixedly connected to the two sides of the filter tank 1, and the diversion chamber 301 is located in the middle as a cavity, and the diversion chamber 301 is located below the cavity and has a drainage channel 309 at an equal distance, and the diversion chamber 301 is located at one side of the cavity and is fixedly connected to a drive motor 2 310 , and the output shaft of the second driving motor 310 is fixedly connected with a rotating guide piece 314 through a coupling, a connecting hole is opened at the top of the diversion chamber 301, and a guide frame 308 is fixedly connected to the top of the diversion chamber 301 located above the connecting hole, and the top of the guide frame 308 is fixedly connected with an inlet cover 302, and a plurality of guide diverter plates 315 are fixedly connected to the inner side wall of the guide frame 308, and the inlet cover 302 is connected to the guide frame 308, and the tops of the guide diverter plates 315 are all located below the inlet cover 302.

[0039] Specifically, in the process of introducing the water drawn from the inside of the breeding pond into the filter tank 1, the water is introduced into the collection cover 302 through the circulation pump 306, and then flows to the space above each drainage channel 309 below under the action of each guide diversion plate 315, and the driving motor 2 310 is started, and the driving motor 2 310 drives the rotating guide plate 314 to rotate, thereby driving this part of the water to various positions of the drainage channel 309, so that it flows evenly through the drainage channel 309 into the arc screen 8 below, thereby improving the initial filtration efficiency of the water body and accelerating the overall progress of the water circulation.

[0040] It should be noted that, during the process of extracting water from the breeding pond, the filter plate 316 blocks large particles of impurities to prevent them from entering the circulation pump 306 and causing damage to the circulation pump 306. At the same time, when the circulation pump 306 stops running, the large particles of impurities below the filter plate 316 are gradually introduced into the collection tube 312 under the action of the obliquely directed arc piece 317, thereby completing the rapid collection of large particles of impurities.

At the same time, when the water flows out from the extrusion channel stack 1001, if the water flow is fast, the water will impact the flow limiting arc plate 1004, and the adaptive spring rod 1007 will be stretched, so that the water can pass quickly. If the water flow is slow, the gap between the flow limiting arc plate 1004 and the extrusion channel stack 1001 becomes smaller, and the thickness of the water flowing to the corrugated plate 1002 is smaller, thereby improving the sterilization effect.
