Description
Technical Field
The utility model belongs to the technical field of breed technique and specifically relates to a solid-liquid separator who is arranged in tilapia fry hatching system.
Background
In the breeding of tilapia fries after hatching, because the feed intake of the fries is small but the feeding times are large, more feed is generated and is sunk into water to become solid precipitate, and excrement is mixed with the solid precipitate, so that bacteria are easy to breed. The prior art has two processing methods: 1) filtering by a water and excrement filtering device and returning clear water to the culture pond; 2) precipitating by a solid-liquid separator (sedimentation tank), and returning clear water to the culture pond.
Both of the above methods have drawbacks: in the first method, the feed which is not eaten by the fry is directly filtered as waste, and the well-known waste which is filtered and intercepted is difficult to separate from the filtering consumables, cannot be utilized and can only be discarded, thereby causing waste; in the second method, filter-feeding big-headed fishes are generally put into a sedimentation tank, and the settled feed is eaten by the big-headed fishes for recycling the settled feed, but obviously, the settled feed discharged into the sedimentation tank and excrement of fries easily sink and finally settle at the bottom of the sedimentation tank (the big-headed fishes cannot be eaten by one hundred percent, and the big-headed fishes can also produce excrement and urine in addition), and are difficult to take out, and in addition, the bottom of the whole tank is sludge (rotten feed and excrement and urine), so that the meat quality of the big-headed fishes is fishy after being inhabited in the environment for a long time.
Disclosure of Invention
To the deficiency of the prior art, the utility model provides a solid-liquid separator with function is collected and takes out to the precipitate, the device still has the effect that improves quality of water in the sedimentation tank.
The technical scheme of the utility model is that:
a solid-liquid separator for among tilapia fry hatching system, including sedimentation tank, inlet tube and overflow pipe, the external fry rearing pond of inlet tube, its characterized in that: the inlet tube sets up the right-hand member at the sedimentation tank, the overflow pipe sets up the left end at the sedimentation tank, a rectangle platform has been laid to sedimentation tank bottom left part, the sedimentation tank bottom just is located the slope that the upper berth on rectangle platform right side was equipped with the top to the right slope, a rectangle basket has been placed in the activity on the position that sedimentation tank bottom just is located the slope right side, one of them lateral wall welding of rectangle basket has a pull rod, the pull rod stretches out in the sedimentation tank top, and the workman of being convenient for pulls out rectangle basket from the sedimentation tank, sedimentation tank upper portion just is gone up to be equipped with a baffle in the position of slope right-hand member face, leave the clearance (can pass through big-head fish at least) between baffle and the slope.
Furthermore, a sand table is movably placed on the top surface of the rectangular platform, the sand table is a stainless steel tray, and aquatic grass sand is uniformly placed in the sand table, so that a comfortable sleeping and resting place is provided for the big-headed fishes.
Furthermore, a plurality of aquatic plant planting frames are fixedly arranged on the slope and used for planting aquatic plants, and the aquatic plants can reduce the concentrations of carbon dioxide, ammonium ions, nitrate ions and the like in water, improve the oxygen content of the water body and improve the water quality; in addition, the material also has certain capacity of absorbing suspended particles.
Furthermore, the handle is welded at the top of the pull rod, so that the pull rod is convenient to grasp.
Furthermore, the rectangular basket is made of stainless steel wires, and the mesh density (mesh number) of the basket is 20 meshes. The diameter of the mesh is about 0.7 mm, and the settled feed and excrement are easy to be fished out because the settled feed and excrement absorb water and have the diameter of more than 0.7 mm.
The utility model discloses a theory of operation:
1) water enters the water inlet pipe;
2) after filling the sedimentation tank, the overflow pipe begins to discharge clear water (clear relative to the inlet water, but obviously not clear water of drinking water standard);
3) the feed and the excrement begin to sink above the rectangular basket in the water inlet process, and due to the blocking of the partition plates, the feed and the excrement do not easily reach the slope, and can slide into the rectangular basket along the landslide even if a small amount of the feed and the excrement reaches the slope;
4) the big-headed fish can forage in the area due to the fact that the rectangular basket and the space above the rectangular basket are rich in feed, and can swim back to a sand table for rest due to the fact that the big-headed fish likes a clear and quiet water area, and the big-headed fish is a filter-feeding animal and cannot gnaw water plants generally, so that water plants on a slope cannot be damaged;
5) after a certain time, workers can pull up the rectangular basket to dump the excrement, and the excrement is cleaned by using a high-pressure water gun after being dumped.
The utility model has the advantages that: be equipped with the rectangle bamboo basket, as the big head fish in the sedimentation tank foraging the food place, the sedimentation tank corresponds the position and is equipped with baffle and slope for the fodder is difficult to leave the sedimentation tank, does benefit to big head fish edible fodder, also does benefit to the workman and retrieves fodder and excrement and urine that deposit in the rectangle bamboo basket, still is provided with the sand table specially in addition, provides the big head fish and has a rest, reduces big head fish contact deposit at submarine rotten material, thereby reduces the mud fishy smell of big head fish.
