Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to a tail water treatment device for grouper aquaculture. Background Art

[0002] The whole body of the grouper is bright red, with high economic and ornamental value. It is a precious farmed fish in the sea. Due to the large market demand, the number of wild populations has dropped sharply due to overfishing, making the grouper a scarce fish in the market. In recent years, with the breakthrough and development of artificial breeding technology of grouper, the breeding scope and scale have gradually expanded. The breeding of grouper requires feeding a large amount of bait, resulting in a large amount of feces, residual bait, nitrogen, phosphorus and other pollutants in the discharged breeding tail water. The direct discharge of a large amount of breeding tail water will cause pollution to the water environment around the breeding area. The breeding tail water needs to be treated before discharge. Most tail water treatment devices intercept impurities in the water by setting filter plates, but the intercepted impurities adhere to the surface of the filter and are difficult to clean. The filter plate needs to be removed, and the bottom of the treatment pool is also prone to precipitation and accumulation of impurities, which is more troublesome to clean manually. Summary of the invention

[0003] The technical problem to be solved by the utility model is that the intercepted impurities adhere to the surface of the filter and are difficult to clean, and the filter plate needs to be disassembled, and the bottom surface of the treatment tank is also prone to precipitation and accumulation of impurities, which is troublesome to clean manually.

[0004] To solve the above problems, the technical solution adopted by the utility model is: a tailwater treatment device for grouper aquaculture, comprising a treatment tank and a top plate fixed at the upper end of the treatment tank, a filter plate being slidably provided inside the treatment tank, the treatment tank being divided into an inlet chamber and a drainage chamber by the filter plate, a water inlet pipe connected to the water inlet chamber being provided on one side of the treatment tank, a water outlet pipe connected to the drainage chamber being provided on the other side of the treatment tank, a fixed plate being fixedly provided at the upper end of the interior of the drainage chamber, a sliding rod being movably penetrated through the middle of the fixed plate, one end of the sliding rod being fixedly connected to the filter plate, the filter plate and the fixed plate being connected by a spring, a cleaning port being provided at the bottom of the drainage chamber, a sealing plate matching the cleaning port being provided on one side of the filter plate, and a cleaning assembly being provided inside the water inlet chamber.

[0005] The beneficial effects of the utility model are as follows: by setting a cleaning port, a sliding filter plate and a sealing plate, the staff can squeeze the cleaning port to make the cleaning port expand, so that the staff can easily scrape and clean the impurities at the bottom of the treatment pool and the impurities on the surface of the filter plate, and discharge them from the cleaning port.

[0006] As a further improvement of the present invention, the technical problem to be solved is that it is laborious to manually clean the impurities remaining inside the treatment pool, and external tools are needed for the operation.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the cleaning component includes a rotating plate symmetrically rotatably arranged inside the water inlet chamber and a mounting shell fixedly arranged at the upper end of the top plate, the two rotating plates are rotatably connected to the bottom surface of the water inlet chamber through rotating shafts respectively, the upper ends of the two rotating shafts pass through the mounting shell and are fixedly sleeved with gears that mesh with each other, the upper end of the mounting shell is provided with a motor for driving one of the gears to rotate, and a scraper for scraping the filter plate is provided on one side of the two rotating plates.

[0008] The beneficial effect of the above improvement is: by rotating the rotating plate and the scraper, when the inside of the treatment pool needs to be cleaned, the scraper is deflected and squeezed on the surface of the filter plate. At this time, the scraper scrapes along the surface of the filter plate and pushes the filter plate to move, thereby gradually misaligning the sealing plate and the cleaning port, so that the cleaning port is opened, and the impurities scraped off fall out of the cleaning port.

[0009] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to carry out preliminary sedimentation treatment of sewage.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: sealing plates that cooperate with each other are provided on one side of the two rotating plates, and water holes are opened on the surfaces of the two rotating plates.

[0011] The beneficial effect of the above improvement is: by setting the sealing plate and the water outlet, when the two sealing plates are in close contact with each other, the water in the water inlet chamber is initially precipitated, and then filtered by the filter plate after passing through the water outlet, thereby improving the filtering and purification effect.

[0012] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to clean up the impurities precipitated in the water inlet chamber at the same time.

[0013] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the lower end surfaces of the rotating plate and the scraper are in close contact with the bottom surface of the treatment tank.

[0014] The beneficial effect of the above improvement is that the rotating plate and the scraper can scrape and sweep the impurities deposited on the bottom surface of the water inlet chamber and push them to the side of the cleaning port during the deflection process.
