Description
Technical field
The artificial shrimp nest that the utility model belongs to artificial shrimp nest design and cultivation water environment control technology field, the particularly a kind of freshwater shrimp ecological matrix device of holding concurrently.
Background technology
Freshwater shrimp (Macrobrachium nipponense), formal name used at school Japanese macrobrachium supernbum, is the important economic freshwater shrimps of China.It is nutritious, fine and tender taste, delicious flavour, and its culture-cycle is short, input cost is low, and economic worth advantages of higher, is subject to liking of consumers in general and raiser deeply.At present, the artificial shrimp nest that is applied to shrimp culture mainly contains the artificial shrimp nest that water peanut, tea tree branch, willow branch, bamboo branch or plastics make, and the service life that they have is short, easy polluted water in rotten process, some hard degradations, also can cause potential hazard to ecotope.Ecological matrix technology is a kind of novel artificial Water quality restoration and the technology of maintenance, and the ecological matrix being applied at present in aquaculture mainly contains shabby net sheet, hairbrush, hollow plastic pellet, nonwoven, A Keman, bamboo silk etc.Shabby net sheet, hairbrush, hollow plastic pellet be as artificial synthetic biofilm carrier, and they exist long, the shortcoming such as bioaffinity is poor of biofilm time, and price is comparatively expensive, post-processed is comparatively loaded down with trivial details; Nonwoven is applied to as ecological matrix in the cultivation of grass carp and carp, can effectively remove total nitrogen, nitrous acid nitrogen in pond water quality, can also improve fish growth speed simultaneously, reduce its feed coefficient, improve its immunity, but nonwoven average price is 40 yuan/m
2, material difficult degradation; The climing ecological matrix of A Ke has more alveolate texture compared with nonwoven, and specific surface area is larger, and in processing water, ammonia nitrogen effect is higher, and its price is more expensive, is mainly used in high density pollution waters, and also has the difficult problem of degraded.Bamboo silk is widely used in cultivating pool as ecological matrix, and it has good removal ammonia nitrogen, permanganate indices effect, but to the cultivation later stage, bamboo silk is perishable, and biomembrane easily comes off, and causes later stage water treatment effect not good.Therefore be badly in need of developing degradable, material source is extensive, cheap, adsorptivity is strong, stability the is strong facility that possesses artificial shrimp nest, ecological matrix dual-use function.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, the ecological matrix device and the artificial shrimp nest that proposes a kind of freshwater shrimp is held concurrently.
The utility model solves its technical problem and takes following technical scheme to realize:
The artificial shrimp nest of a kind of freshwater shrimp the ecological matrix device of holding concurrently, comprise the rectangle steel net sheet of being shaped by steel framework, evenly on steel net sheet in steel framework be fixed with middle reinforced rib apart from interval, on steel net sheet, be horizontally installed with two groups of parallel plastic tubes from bottom to top, one side of each rectangle palm sheet is packed on one group of plastic tube, and keep palm plate plane to become vertical state with plastic tube, described palm sheet is two rows, every row is for multiple even apart from interval and the palm sheet being parallel to each other, in the top of described steel framework and below all bolt has stationary rope on steel wire.
And, the length × wide 3m × 1m that is of a size of of described rectangle steel framework, described steel framework gauge of wire is 0.5cm, and in described steel framework, the square aperture of steel net sheet is 5.0cm × 5.0cm, and the steel wire diameter of braiding steel net sheet is 0.15cm.
And the spacing between described upper and lower two groups of plastic tubes is 30cm, in every group of plastic tube, the spacing of two tubes is 20cm.
And, described every row multiple even apart from interval and the palm sheet being parallel to each other be 15, every palm sheet is fastened on every group of plastic tube by iron wire by a pair of fixing hole of one side.
Advantage of the present utility model and good effect are:
1, the utility model Stability Analysis of Structures, durable.
2, the artificial shrimp nest of the present utility model ecological matrix material adsorptivity of holding concurrently is strong, and not only effectively increase the space of perching and ingest of freshwater shrimp, but also can be used as the bed of growth of microorganism, be a kind of new bio carrier, can be used as ecological matrix and purify water.
3, member of the present utility model can freely mount and dismount, and uses simple and convenient.
4, the artificial shrimp nest of the present utility model ecological matrix of holding concurrently cleans after using every year, after cleaning, can again utilize, and has saved production cost.
5, the utility model is simple in structure, manufacturing cost is lower, artificial shrimp nest is held concurrently ecological matrix stability of material better, can degrade, not pollute the environment, be easy to promote.
