In the description of the present embodiment, it should also be noted that the terms "disposed," "connected," and "connected" are to be construed broadly, unless explicitly stated or limited otherwise.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, the embodiment discloses a water treatment device for aquaculture, which comprises a tank body 100, wherein a filter assembly 200 is arranged in the middle of the inner side of the tank body 100, and the space in the tank body 100 is divided into an upper tank area and a lower tank area by the filter assembly 200. An inner container 160 is arranged in the lower tank area of the tank body 100, the top of the inner container 160 is of an open structure, and the upper edge of the inner container 160 is in sealing contact with the inner side wall of the lower tank area of the tank body 100, so that water moving downwards through the filter assembly 200 completely enters the inner container 160. An outer cavity space is left between the side surface and the lower part of the inner container 160 and the lower tank area of the tank body 100. The water outlets 110 are uniformly formed in the side wall of the inner container 160, and all the water outlets 110 incline along the same circumference, so that water flowing out of the inner container 160 can form rotary water flow in the outer wall space, and meanwhile, the water flow at the inner side of the inner container 160 can also generate certain rotation. The bottom of the tank body 100 is provided with a water outlet pipe 120, and the rear end of the water outlet pipe 120 is connected with a water pump 300. The outer cavity space at the side of the lower tank area of the tank body 100 is provided with a first impeller 410, and the axis of the first impeller 410 coincides with the tank body 100. The middle part of the tank area on the tank body 100 is provided with a second impeller 440, a disturbance impeller 420 is arranged above the filter assembly 200, and the rotating shafts of the first impeller 410, the second impeller 440 and the disturbance impeller 420 are mutually and coaxially connected, so that rotation can be transmitted. The upper tank farm of the tank body 100 is also provided with an impurity capturing assembly 500. The upper tank area of the tank body 100 is provided with a water inlet pipe 130. The sewage enters the upper tank area from the water inlet pipe 130 and is finally pumped out by the water pump 300, and under the action of the water pump 300, the water continuously enters the inner container 160 of the lower irrigation area from the upper tank area, then enters the outer cavity space through the water outlet 110 and is finally discharged through the water outlet pipe 120. The rotary water flow in the outer cavity space of the lower tank area of the tank body 100 drives the first impeller 410 to rotate, the first impeller 410 drives the second impeller 440 and the disturbance impeller 420 to rotate, the second impeller 440 drives the water flow in the upper tank area of the tank body 100 to rotate, the rotary water flow continuously flows through the impurity capturing component 500, and the impurity capturing component 500 continuously captures solid impurities in water. Solid impurities in the water are blocked by the filter assembly 200 at the upper tank area of the tank body 100, and the water continuously flows into the lower tank area of the tank body 100 through the filter assembly 200. The perturbation action of the perturbation impeller 420 is such that solid impurities blocked at the tank farm on the tank body 100 do not stay on the surface of the filter assembly 200, but are caught by the impurity catching assembly 500 in continuous motion. The perturbation impeller 420 can also facilitate rotation of the water flow.
The water inlet pipe 130 is located at the top of the tank 100, a water wheel 430 is arranged below the water inlet pipe 130, the axis of the water wheel 430 is horizontally arranged, and the rotating shaft of the water wheel 430 is in transmission connection with the rotating shaft of the second impeller 440 through the transmission assembly 600. The liquid level in the upper tank area of the tank 100 is below the lower edge of the water wheel 430. The water to be treated enters the tank area on the tank body 100 from the water inlet pipe 130, falls down due to the gravity effect and pushes the water wheel 430 to rotate, and the water wheel 430 drives the second impeller 440 and the disturbance impeller 420 to rotate. Through the above technical solution, the second impeller 440 and the disturbance impeller 420 are driven to rotate by the water wheel 430 and the first impeller 410 together.
The tank farm on the tank body 100 is provided with a flocculant feed port 140 for adding flocculant to water, thereby polymerizing the aquatic weeds in the tail water of the aquaculture and the sundries such as dead aquatic animals, and facilitating the catching of the impurity catching assembly 500.
Flocculant feed port 140 is positioned inside inlet pipe 130 so that flocculant is initially mixed with the water to be treated and, after passing through water wheel 430, flows in a rotating manner in the tank area on tank 100, and is more thoroughly mixed.
The inner side of the liner 160 of the lower tank area of the tank body 100 is provided with a medicine feed inlet 150 for adding medicines, such as vitamins, hormones, growth promoters, antibiotics, etc., for improving the water quality of the water body. The added medicine is primarily rotated and mixed in the inner container 160, then rotates along with the water flow in the outer cavity space and collides with the first impeller 410 to be fully mixed, and finally is discharged by the water pump 300.
Referring to fig. 2, the impurity catching assembly 500 includes a filter belt 510, a drain tank 520, an upper roller 530, and a lower roller 540. Both the upper turning roll 530 and the lower turning roll 540 are rotatably mounted on the sidewall of the can 100, wherein the upper turning roll 530 is above the liquid level and the lower turning roll 540 is below the liquid level. The filter screen belt 510 is connected end to end and wound around the upper rotating roller 530 and the lower rotating roller 540 in a tight state, and the upper rotating roller 530 or the lower rotating roller 540 drives the filter screen belt 510 to perform circulating motion. The screen band 510 moves upward on one side that is being flushed by the water flow and downward on the other side. One side of the drain groove 520 contacts with one side of the filter mesh belt 510, which moves downward, scraping off solid foreign matters attached to the filter mesh belt 510. The drain groove 520 is inclined, and is low near one end of the sidewall of the tank 100 and high near one end of the middle of the tank 100. The lower end of the drain tank 520 penetrates the sidewall of the can body 100 so that the solid impurities can be discharged out of the can body 100. The water flow falling from the top falls into the drain tank 520 slightly, and is discharged with solid impurities.
The foregoing description of the preferred embodiments of the present invention should not be taken as limiting the invention, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
