Description

Technical Field

[0001] This utility model relates to the field of aquaculture, specifically to an aquaculture wastewater recycling treatment device. Background Technology

[0002] With the rapid development of aquaculture in my country, the issue of wastewater and tailwater discharge from aquaculture has gradually attracted attention and importance. During aquaculture, the presence of a large amount of aquatic plants, garbage, insoluble plankton, and leftover feed residue and aquatic animal excrement in the water can easily lead to eutrophication, resulting in serious exceedances of ammonia nitrogen, nitrite, and phosphorus in the aquaculture water. This causes a decline in water quality, affects the normal feeding and growth of aquatic animals, and can even cause the water to emit foul odors and affect the ecological environment around the aquaculture ponds. Therefore, in the aquaculture process, it is usually necessary to filter the discharged aquaculture tailwater to remove insoluble impurities, ensure solid-liquid separation, and prevent impurities from remaining in the tailwater for a long time and causing environmental pollution.

[0003] However, large aquaculture tanks can usually handle impurities during the aquaculture process due to their large size. Small aquaculture tanks, on the other hand, require the aquatic products to be removed before cleaning, and the back-and-forth movement can easily lead to the death of the aquatic products. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an aquaculture wastewater recycling treatment device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an aquaculture wastewater recycling treatment device, including an aquaculture tank and a purification tank. The aquaculture tank is equipped with a slag discharge mechanism, and the slag discharge mechanism is equipped with a placement frame. The upper surface of the placement frame has an array of insertion grooves, and the insertion grooves are equipped with intercepting mesh plates. The lower surface of the placement frame has a cover plate groove, and the inside of the cover plate groove, on the side away from the purification tank, is equipped with a slag scraper. The upper surface of the placement frame, on the side away from the slag scraper, is equipped with a fixed pulley frame, and a pull rope is provided between the fixed pulley frame and the slag scraper.

[0006] As a further embodiment of this utility model: a drainage pump is connected between the breeding chamber and the purification chamber, and an adsorption baffle is installed in the internal array of the purification chamber.

[0007] As a further improvement of this utility model: the side surface of the breeding silo is provided with an installation slot, and an installation block is installed on the outer side of the placement rack corresponding to the inner side of the installation slot.

[0008] As a further improvement of this utility model: a rubber gasket is installed on the outer wall of the slag scraper, and the slag scraper is slidably positioned with respect to the sliding groove of the cover plate.

[0009] As a further improvement of this utility model, the pull rope is fixedly connected to the slag scraper.

[0010] As a further improvement of this utility model: the drainage pump is connected in a continuous manner to the breeding chamber and the purification chamber, and the adsorption partition is filled with biological filler.

[0011] As a further improvement of this utility model, the outer diameter of the placement rack matches the inner diameter of the breeding chamber.

[0012] As a further improvement of this utility model: the placement rack is engaged with the mounting slot via the mounting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The pull rope drives the entire scraper plate to move inside the cover plate groove, causing the scraper plate to push the impurities adhering to the inside of the breeding tank towards the drain pump. This allows for sludge removal and purification without completely draining the water from the breeding tank.

[0015] When no intercepting net is placed inside the aquaculture rack, the impurities produced by the feeding will all settle inside the aquaculture tank. When the intercepting net is placed, there is no need to move the aquatic products, and the water will not become turbid when scraping the sludge. Attached Figure Description

[0022] 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.

[0023] like Figure 1-5 As shown, this embodiment provides an aquaculture wastewater recycling treatment device, including an aquaculture chamber 1 and a purification chamber 5. The aquaculture chamber 1 is equipped with a slag discharge mechanism 3, and a placement rack 301 is installed inside the slag discharge mechanism 3. The outer diameter of the placement rack 301 matches the inner diameter of the aquaculture chamber 1. The upper surface of the placement rack 301 has arrayed insertion grooves 302, and an intercepting mesh plate 304 is installed inside the insertion grooves 302. The intercepting mesh plate 304 can be selected according to the type of impurities in the aquaculture water. The material of the aperture is set, and a cover plate groove 308 is opened on the lower surface of the placement rack 301. A scraper plate 307 is set inside the cover plate groove 308 on the side away from the purification chamber 5. A rubber gasket is installed on the outer wall of the scraper plate 307. The scraper plate 307 and the cover plate groove 308 are limited and slidably set. A fixed pulley frame 305 is installed on the upper surface of the placement rack 301 on the side away from the scraper plate 307. A pull rope 306 is set between the fixed pulley frame 305 and the scraper plate 307. The pull rope 306 is fixedly connected to the scraper plate 307.

[0024] like Figure 2-3 As shown, in this embodiment, a drainage pump 4 is connected between the aquaculture tank 1 and the purification tank 5. The drainage pump 4 is connected to both the aquaculture tank 1 and the purification tank 5. An adsorption baffle 6 is installed in the internal array of the purification tank 5. The adsorption baffle 6 is filled with biological filler. The biological filler can be determined according to the composition of impurities in the aquaculture water. An installation slot 2 is provided on the side surface of the aquaculture tank 1. An installation block 303 is installed on the outer side of the placement rack 301 corresponding to the inner side of the installation slot 2. The placement rack 301 is engaged with the installation slot 2 by the installation block 303.

[0025] The working principle of this utility model is as follows: During use, the aquaculture tank 1 can be used for aquaculture. Before aquaculture, the sludge removal mechanism 3 is inserted and positioned inside the mounting slot 2 using the mounting block 303. During aquaculture, no intercepting mesh plate 304 is placed inside the placement rack 301. Therefore, impurities generated from feeding will settle inside the aquaculture tank 1. When the aquaculture water inside the tank 1 needs cleaning, the intercepting mesh plates 304 can be placed one by one from one side of the sludge removal mechanism 3 into the insertion groove 302. This separates the aquatic products above the sludge removal mechanism 3, allowing the aquatic products to be cleaned. By pulling the rope 306, which is wrapped around the fixed pulley frame 305, the rope 306 drives the scraper 307 to move inside the cover plate groove 308. This causes the scraper 307 to push the impurities adhering to the inside of the breeding tank 1 towards the drain pump 4. At the same time, it prevents a large amount of impurities from mixing with the water when scraping. The drain pump 4 drives the impurities and tailwater in the lower position to be absorbed and discharged into the purification tank 5. It is not necessary to completely empty the water in the breeding tank 1. After the tailwater and impurities are discharged into the purification tank 5, the water is purified by the packing material inside the adsorption baffle 6.
