Description

Technical Field

[0001] The present invention belongs to the technical field of water cycle treatment, and specifically relates to a device and method for water cycle treatment. Background Art

[0002] According to the patent document with the authorization announcement number "CN215774984U" and the invention name "A water circulation device for aquaculture", it is recorded in its specification that during the use of the water circulation device for aquaculture, first, the device is placed on the surface of the river water, and then the water pump is turned on. Under the action of the water pump, the water intake starts to absorb the river water, and a filter screen is arranged inside the water intake. The filter screen can simply filter the river water sucked into the water circulation device to prevent large-volume sundries from blocking the pipeline. At the same time, the water pump transports the river water to the inside of the sand filter tank through the first connecting pipeline to further filter the absorbed river water, improve the quality of the river water, remove harmful substances in the river water, and the sand filter tank transports the filtered river water to the inside of the water collection tank through the second connecting pipeline. After being buffered by the water collection tank, the river water flows into the inside of the foam separator through the water delivery pipeline, filtering out suspended solid particles in the water, removing ammonia nitrogen in the water, adjusting the acid-base neutralization degree of the river water, and at the same time, the processed river water is treated by an oxygenation pump to increase the oxygen content in the river water. The water is returned to the river water through the oxygenation spray disc and the spray pipeline, and the spray pipeline and the oxygenation spray disc can increase the oxygen content in the aquaculture water, making the river water more suitable for fish survival and achieving the effect of water cycle. However, there are still the following defects:

At the same time, the rotating conical plate 7081 is arranged in a conical shape, so that the water is sprayed towards the ozone inlet position, improving the acting force between the water and ozone and improving the sterilization reaction effect.

[0042] The water communication member 707 includes an internal cavity 7071 opened inside the rotating shaft 703. A communication control member 709 is arranged inside the internal cavity 7071. Upper communication holes 7072 are equally angled and opened on the outer wall of the internal cavity 7071.

When the water treatment tank 1 is placed upright, the upper communication hole 7072 and the lower communication hole 7073 are respectively communicated with the filtered completion cavity and the spraying and throwing cavity, facilitating the flow of water for spraying and sterilization. When the water treatment tank 1 is inverted, the active stop cylinder 7094 moves downward, opening the intake slots 7091, the first ventilation slots 7095, and the second ventilation slots 7096, while closing the lower communication hole 7073, enabling the clean air to backwash the first filter cartridge 502, the second filter cartridge 503, and the third filter cartridge 504, facilitating cleaning.

[0044] A drain pipe 2 is installed at the bottom end of the water treatment tank 1. A first valve 3 is installed on the drain pipe 2. A rotation driving mechanism is arranged on the back of the water treatment tank 1. The rotation driving mechanism is used to drive the water treatment tank 1 to rotate and invert.

[0045] Working principle: During the process of aquatic product water treatment, the water to be treated is introduced into the intake ring 505 through the total intake pipe 507, and then dispersed into the initial intake cavity formed by the water treatment tank 1 and the first filter cartridge 502 through each intake branch pipe 506. Then the water flows along the inclined interior of the fixed conical plate 501, enabling the water to pass through the first filter cartridge 502, the second filter cartridge 503, and the third filter cartridge 504 in sequence, thus completing three - stage filtration;

[0046] At this time, under the action of gravity, the top wall of the active stop cylinder 7094 is flush with the top wall of the fixed stop rod 7093, and the active stop cylinder 7094 closes the intake slots 7091. The upper communication hole 7072 and the lower communication hole 7073 on the inner cavity 7071 are respectively communicated with the filtered completion cavity and the spraying and throwing cavity. After the water enters the filtered completion cavity, it enters the inner cavity 7071 through the upper communication hole 7072, and then enters the spraying and throwing cavity between the fixed conical plate 501 and the rotating conical plate 7081 through the lower communication hole 7073;

[0047] During use, the drive motor 706 operates to drive the driving gear 705 to rotate. The driving gear 705 meshes with the driven gear 704 on the rotating shaft 703, thereby driving the rotating shaft 703 to rotate, and then driving the rotating conical plate 7081 to rotate. As a result, the water entering the spray and centrifugal chamber is dispersed and thrown into the space below the rotating conical plate 7081 under the action of centrifugal force. At this time, the intake pipe 603 is connected to the ozone generator, and ozone enters the interior of the water treatment tank 1 evenly and dispersedly through the intake holes 602. At this time, the sprayed water comes into violent contact with ozone, improving the uniformity and effect of ozone sterilization and disinfection of water;

[0048] After the treated water is discharged from the drain pipe 2, the first valve 3 is in the open state at this time. When the first filter cartridge 502, the second filter cartridge 503, and the third filter cartridge 504 are blocked due to a large amount of impurities filtered on them, the first valve 3 is closed at this time, and the intake pipe 603 is disconnected from the ozone generator. The water treatment tank 1 is rotated and inverted by the rotation driving mechanism, and then the intake pipe 603 is connected to the clean air backwashing device. After the water treatment tank 1 is inverted, the movable baffle cylinder 7094 inside the internal cavity 7071 moves downward under the action of gravity until the end of the movable baffle cylinder 7094 contacts the limit ring 7092, so that the intake groove 7091, the first ventilation groove 7095, and the second ventilation groove 7096 are opened, and the lower communication hole 7073 is closed. At this time, the clean air backwashing device is started. After the clean air enters the interior of the water treatment tank 1, it passes through the intake groove 7091, the first ventilation groove 7095, the second ventilation groove 7096, and the upper communication hole 7072 and enters the filtered cavity, and backwashes the impurities in the filter holes of the first filter cartridge 502, the second filter cartridge 503, and the third filter cartridge 504, flushing the impurities onto the top cover body 401. Then, the top cover body 401 is removed, the impurities are collected, and then the water treatment tank 1 is rotated back to the upright position to perform subsequent water treatment.
