Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, in particular to a dirt collection device for high-density culture of Acrossocheilus fasciatus. Background Art
[0002] Acrossocheilus fasciatus is commonly known as grouper and Ross fish. It lives in mountain streams and is a small omnivorous stream economic fish, widely distributed in the streams of Jiangsu, Zhejiang, Jiangxi, Anhui, Fujian and other places. Because Acrossocheilus fasciatus has beautiful markings and grows in the cracks of mountain stream stones, people call it "grouper". It has delicate meat, delicious taste and rich nutrition. The market price is more than 100 yuan per kilogram, with high value.
[0003] Traditional artificial culture of Acrossocheilus fasciatus mainly focuses on hilly areas, using stream water for flowing water culture. The stocking density per mu is less than 15,000 tails per mu, and the average yield per mu is usually 200-500 kilograms, with a culture cycle of more than 18 months. Generally, it is considered that the original living environment of Acrossocheilus fasciatus is mountain streams, so the culture pond requires good water quality and high transparency. However, when the water quality is too clear, the natural biological bait is relatively scarce, and at the same time, parasitic diseases are prone to occur, affecting the yield. The key to carrying out high-density culture experiments of Acrossocheilus fasciatus is to improve the water body fertility while always paying attention to the water quality situation to prevent the deterioration of the water environment.
[0004] Traditional aquaculture does not suck dirt or replaces sucking dirt with water change in daily production. After all the commercial fish are fished and sold at the end of a culture cycle, the pond is then emptied and dredged. It is often prone to deterioration of the bottom quality and water quality in the middle and late stages of culture, resulting in the disease of cultured fish. The emerging in-pond recirculating flow fish culture collects the cultured dirt deposited in the dirt collection area by installing a waste collection device at the other end of the "water tank". Factory or factory-like fish culture requires the design and pre-burial of a complete sewage system before production, with a large investment in construction time and cost. Summary of the Utility Model
[0005] Aiming at the problem of dirt collection in the process of high-density culture of Acrossocheilus fasciatus in existing ponds, the utility model researches and constructs a dirt collection device for high-density culture of Acrossocheilus fasciatus, and improves the culture efficiency and water quality management effect by reasonably designing the pond structure and sewage system.

[0021] See also Figure 1 Aiming at the problem of waste collection in the process of high-density breeding of smooth lipped fish in existing ponds, the utility model studies and constructs a new type of simple and practical waste collection device: the original pond is rectangular, with an area of about 3 mu, a bottom of fine sand, and an average water depth of 2 to 2.5 m; the original pond 1 is transformed into a pot-bottom shape with high sides and low middle; a groove-type sewage suction trough 2 with a width of 100 cm × length of 200 cm × depth of 80 cm is built with cement bricks in the center of the pond, and a stainless steel porous plate 3 is covered on it; the sewage suction trough 2 is connected to the wastewater pool 8 with a sewage suction pipe, and a siphon 601 is led out of the sewage suction pipe to the valve well as a switch for sewage suction; at the same time, 4 1.5-kilowatt waterwheel-type aerators are installed at the four corners of the pond to stir the pool water to form a micro-circulation water flow in the pool.
[0022] The device process design provided in this embodiment is as follows:
[0023] 1. Installation conditions
[0024] After the pond is dried and dredged, the pond bottom 101 is leveled and transformed into a pot-shaped bottom with high sides and low middle, so that the dirt will gather in the middle (the pond bottom 101 is at a relative elevation of 0.00m); the drainage channel (wastewater pool 8) is sound, and the relative elevation of the channel bottom is less than 1.40m.
[0025] 2. Device design
[0026] The device consists of three parts: a sewage suction tank 2, a sewage suction pipeline and a control system.
[0027] Sewage suction tank 2: In the middle of the pond bottom, a grooved sewage suction tank with a width of 100 cm, a length of 200 cm, and a depth of 80 cm is built with cement bricks, and a stainless-steel perforated plate 3 is covered on it. The upper edge of the groove is at the same height as the lowest point of the pond bottom; the stainless-steel perforated plate is in a "V" shape with a pore diameter of 5 mm. This allows dirt such as the excrement of cultured fish in the pond to settle.
[0028] Sewage suction pipeline: A PE pipe is used to connect the sewage suction tank to the drainage channel, and the PE pipe can be laid along the pond wall. From the sewage suction tank to a relative elevation of 1.40 m, a PE pipe with a DN110 is used as the primary sewage discharge pipe 4, and from a relative elevation of 1.40 m to the drainage channel, a PE pipe with a DN75 is used as the secondary sewage discharge pipe 5; in addition to sealing the connection between the two pipes of different specifications, a tee joint is set and another DN50 PE pipe is led out as an air inlet pipe.
[0029] Control system: The above-mentioned DN50 PE pipe is led into the valve well as the air inlet pipe 601, and a valve switch is set. The valve is externally connected to a blower or an air pipe of the same type as the blower, and a 1.5-kilowatt blower is used for air supply.
[0030] Exemplarily, the dirt collection device for high-density Acrossocheilus fasciatus farming provided by the present utility model operates as follows:
[0031] Sewage suction: 60 to 90 minutes (depending on the specific season, feeding situation, etc.) after each feeding, the valve switch is opened, air is blown in through the air inlet pipe 601, and the air flow sprays out from the dirt outlet through the secondary sewage suction pipe 5, forming a negative pressure suction on the primary sewage suction pipe 4, driving the sewage in the sewage suction tank 2 to be discharged through the primary sewage suction pipe 4 and the secondary sewage suction pipe 5. Each sewage suction takes about 3 to 5 minutes or so, and the valve is closed until the sucked sewage is the same color as the pond water, and the sewage suction immediately stops.
[0032] Implementation situation of the present utility model:
[0033] Through production tests in the breeding base of Hangzhou Liangda Aquaculture Co., Ltd. in the 17th section outside the reclamation area of Xiaoshan District, high-density breeding is carried out in the facility greenhouse, with a stocking density of 40,000 tails per mu. On the one hand, the number of natural baits such as plankton in the pond is increased by appropriate fertilization, and on the other hand, the preset dirt collection device is used for regular sewage suction to maintain a good water quality environment in the breeding pond. After 13 months of breeding, a yield of more than 1400 kg per mu is achieved, obtaining good economic, ecological and social benefits.
[0034] Compared with the prior art, the present utility model has the following beneficial effects:
[0035] 1. Save construction time. Traditional sewage suction devices require excavation and pre-burial of sewage pipes at the bottom of the pond, with a large amount of engineering work and a construction time of at least over 1 month. This utility model only needs to excavate a groove with a width of 100 cm × length of 200 cm × depth of 80 cm, equipped with auxiliary materials such as PE pipes, and the construction time can be shortened to 10 days.
[0036] 2. Energy saving. The power configuration of the sewage pump in this utility model is a 1.5-kilowatt blower for air supply, which can not only ensure the sewage discharge of multiple ponds in turn, but also be used as bottom aeration for the pond usually, which is convenient for one device to serve multiple functions, energy-saving and environmental-friendly. At the same time, due to the small power and short usage time of this utility model, the need to replenish water for the aquaculture pond due to long-term operation of the equipment can be reduced.
[0037] 3. High efficiency. Acrossocheilus fasciatus used in this utility model for aquaculture belongs to small fish, and the specification of commercial fish is within 20 tails / kg. Therefore, dirt such as artificial feed input and excrement produced by fish can enter the sewage suction tank through a 5-mm aperture. At the same time, 4 1.5-kilowatt water-wheel aerators are equipped at the four corners of the pond to stir the pond water to form a microcirculation water flow in the pond for better collection of dirt. When the device is running, the suction force formed by the airflow drive is very large, which can easily eject the small-particle dirt gathered in the sewage suction tank from the dirt outlet to achieve the effect of sewage discharge.
[0038] 4. Results. Through production tests in the breeding base of Hangzhou Liangda Aquaculture Co., Ltd. in the 17th section outside the reclamation area of Xiaoshan District, high-density breeding is carried out in the facility greenhouse, with a stocking density of 40,000 tails per mu. On the one hand, the number of natural baits such as plankton in the pond is increased by appropriate fertilization, and on the other hand, the preset dirt collection device is used to suck sewage regularly to maintain a good water quality environment in the aquaculture pond. After 13 months of breeding, the yield per mu reaches more than 1,400 kilograms, achieving good economic, ecological and social benefits.
