Description

Internal circulation aquatic product live storage ship

technical field

The utility model relates to a fishery transport ship, in particular to an internal circulation live storage ship for aquatic products.

Background technique

At present, the commonly used live fish transport ships all adopt the technical mode of transporting water bodies that can be renewed. The practical live fish transport ship for fishery is made of steel or wood, and the shell of the hull is water-proof and seamless. The water in the main cabin of the wooden ship is pumped from the reservoir. During transportation, the water in the main cabin cannot be exchanged for fresh water rich in dissolved oxygen, or only part of it can be exchanged, which cannot meet the survival requirements of live fish. The survival rate of transportation Low. Both ends of the steel live fish transport ship are equipped with airtight chambers to provide buoyancy, and two ends are also equipped with adjustment chambers to adjust the draft of the hull. This kind of live fish transport ship is convenient for lifting fish, but when transporting live fish, the water body in the main cabin cannot be exchanged for fresh water rich in dissolved oxygen, or only part of the exchange can be realized, which cannot meet the survival requirements of live fish, and the transport survival rate is low. And the manufacturing process of steely and wooden ship is complicated, and cost is high, and transportation cost is high. Such as Chinese utility model patent "live fish carrier", patent No. 200420110764.8, which discloses a carrier, especially relates to a live fish carrier for fishing operations in large and medium-sized reservoirs and lake fisheries. A live fish transport ship, comprising a hull of the boat and a cabin disposed therein, the cabin is provided with a deck, the hull of the boat is made of moso bamboos connected in series to form the whole hull, and the moso bamboos are kept There is a certain gap. The purpose of this utility model is to provide a live fish transport ship that can not only realize the renewal of the water body in the cabin, but also ensure the survival rate of live fish, and at the same time, the cost of the transport ship is relatively low, and it is easy to manufacture, so as to solve the problems existing in the prior art. The water body in the cabin cannot be renewed, and the transportation cost is high. However, when it is used for long-distance transportation, it brings the risk of alien biological invasion.

In the actual application process, when the sewage treatment bacteria grow evenly, the single or multiple bacteria bed frames can be removed as needed and transferred to other ammonia nitrogen that needs to be treated. The treatment pool, so that other inoculated pools can quickly reach the cloth bacteria density required for treatment. The attachment base clamped in the twisted gap also has the same function of adjusting the density of cloth bacteria on demand. During use, the attachment base can be added or removed as needed to adjust the bacterial density, and the attachment base can also be transferred to inoculate sewage treatment bacteria. The role of rapid scale-up of water treatment.

A baffle is arranged near the middle of the foam separation tank; the side of the baffle close to the water inlet is paved with sand and gravel.

Near the water outlet in the ammonia nitrogen treatment pool, there is an ammonia nitrogen detection device that can control the three-way valve according to the ammonia nitrogen content.

Because the utility model adopts the solid-liquid separation tank, the ammonia nitrogen treatment tank, the foam separation tank, the ultraviolet ray sterilizing device and the breeding pond that are connected successively to form a circuit in the hull; the bottom of the solid-liquid separation tank body of the solid-liquid separation tank The side is inclined and there is a sewage pipe near the bottom; the bottom of the solid-liquid separation tank is evenly distributed with aeration discs; above the aeration discs, there are solid-liquid separation discs arranged in gaps and arranged obliquely; the solid-liquid separation discs The lower side of the tank is evenly distributed with dense holes, and the solid-liquid separation plate is also connected with a solid-liquid separation outlet pipe. The aquaculture sewage enters the solid-liquid separation tank body through the water inlet pipe, churns under the action of the gas of the aeration plate and passes through the densely pore surface of the solid-liquid separation plate. The solids in the sewage are washed away by air bubbles and leave the surface with dense pores, and the liquid water enters the inner side of the solid-liquid separation plate through the dense pores on the surface of the dense pores, and is transported to the next treatment tank through the solid-liquid separation outlet pipe. The solid waste finally settles near the sewage pipe and can be collected and dried for centralized treatment after being discharged through the sewage pipe. Therefore, the utility model has the advantages of low operating cost, low cost, good stability, high breeding density, controllable scale of ammonia nitrogen treatment on demand, and no risk of foreign organism invasion.
