Description
Technical field
The utility model belongs to aquaculture water-treatment technology field, filters more particularly, to a kind of intensive culture shrimp ponds recirculated water
Device.
Background technique
In the prawn culturing later period, with the growth of prawn, feeding amount and excrement discharge increase severely, and microorganism will be big in pond waters
Amount ammoniacal nitrogen is oxidized to nitrite nitrogen, since the degree that nitrite nitrogen is oxidized to nitrate nitrogen is oxidized to nitrous well below ammoniacal nitrogen
The speed of state nitrogen causes a large amount of accumulation for occurring nitrite nitrogen in water body, and it is anti-that the accumulation of nitrite can directly result in prawn
The reduction of sick power causes the secondary invasion of various pathogens, is usually deemed to be the pathogenic root of prawn, probiotics
It uses, nitrite nitrogen can be effectively reduced, but cause the excessive breeding of zooplankter simultaneously, it is right that oxygen consumption, which increases severely, in shrimp-cultivation pool
Shrimp aquaculture has buried hidden danger.The outburst for cultivating later period blue-green alge simultaneously, more adds fuel to the flames, is further degrading prawn culturing ring
Border causes prawn survival rate and cultured output seriously to reduce.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of intensive culture shrimp ponds recirculated water filtering dress
It sets.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of intensive culture shrimp ponds Circulated water filter, including bottom water tank are successively fixed in the top of water tank
One layer of water tank, second layer water tank, third layer water tank and top layer water tank are equipped with top plate at the upper opening of the top layer water tank,
It is provided with blasthole on the left of top plate, filter layer is filled in the inside of each layer water tank, on the bottom plate of each layer water tank
Leakage hole is offered, adjacent layer leak hole site interlocks, and the mesh enclosure for stopping filter layer is mounted on each leakage hole, each
The side wall upper part of layer water tank is provided with handle hole, is equipped with hinge shaft in the bottom outside of handle hole, and dress and operation are twisted on hinge shaft
The sealing cover of hole cooperation, retaining ring that sealing cover is installed by sealing cover top and the retaining ring seat installed on water tank side wall are interlockingly connected reality
Existing sealing of the sealing cover to leakage hole, is equipped with water circulating pump, the aqueduct of water circulating pump is worn in the bottom water tank
Filtered cultivation water is externally provided after bottom water tank side wall out.
Moreover, the filter layer being filled in inside each layer water tank specifically: second layer water tank, third layer water tank and top
Filter layer in layer water tank is followed successively by the haydite that partial size successively increases, and the filter layer in first layer water tank is coarse sand, every layer of water tank
Interior filtering layer height is not less than the half of this layer of tank height.
Moreover, the first layer water tank, second layer water tank, third layer water tank and top layer water tank height be followed successively by 60cm,
50cm, 40cm and 30cm.
Moreover, being equipped with castor at the bottom plate following four corners of the bottom water tank.
The advantages and positive effects of the utility model are as follows:
1, the Circulated water filter of the utility model solves the problems, such as prawn culturing later period water quality deterioration, bright
It is aobvious to improve prawn culturing yield and survival rate, it escorts for the healthy aquaculture of prawn；
2, the utility model structure is simple, and design is rationally, mobile flexible, easy to use, has preferable promotion prospect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model embodiment is further described below in conjunction with attached drawing, it is emphasized that, following implementation
Be it is illustrative, cannot be in this embodiment as the restriction to the utility model without being restrictive.
