Embodiment two
The present embodiment optimizes the structure of the shrimp ecosystem in above-described embodiment one further.Above-mentioned physical filtering room 10 and above-mentioned filter mechanism 2 also can take the defecator of following structure:
As one of embodiment, the present embodiment provides a kind of siphon filter device, and including filtering ponds 101, described filtering ponds 101 have water inlet 1017 and outlet 1015, are disposed with at least single filter structure 1014 between water inlet 1017 and outlet 1015.Wherein, filtration 1014 includes filtering sieve plate 1014, and each described filtration sieve plate 1014 is the most detachably flush-mounted in described filtering ponds 101；The mode of detachable setting-in uses the mode that grafting is fixing, i.e. offers slot respectively relative to filtration 1014 installed position on the pool wall of filtering ponds 101 both sides, inserts corresponding slot by filtering sieve plate 1014；Detachable setting-in mode can change screen cloth according to site specific, reaches different filtering accuracies.
Optimize the structure of above-mentioned defecator further, such as Fig. 1, each described filtration sieve plate 1014 is all that an angle is arranged with vertical direction, and the horizontal range of every piece of described filtration sieve plate 1014 top and described outlet 1015 is more than the horizontal range of its bottom with described outlet 1015.The most each filtration sieve plate 1014 is obliquely installed, and incline direction is towards water inlet 1017 side.Filtration sieve plate 1014 is obliquely installed, the area filtering sieve plate 1014 can be increased first, improve filter effect, second make the dirt being jammed on sieve aperture be prone to be settled down at the bottom of pond, also can improve backwash effect when sieve plate 1014 backwash is filtered in blocking.
Such as Fig. 1, for the structure of above-mentioned filtering ponds 101, usually, sewage draining exit 1016 was set before every grade of filtration 1014, for being discharged outside pond by the dirt being settled down at the bottom of pond；That is: bottom filtering ponds 101, it is provided with multiple sewage draining exit 1016, the quantity of sewage draining exit 1016 is identical with the quantity of filtration 1014, and one_to_one corresponding is located at each filtration 1014 side away from described outlet 1015, when multistage filtering structure 1014, between every adjacent double filtration design 1014, there is an above-mentioned sewage draining exit 1016.
Optimize the structure of above-mentioned defecator further, being provided with water distributing plate 1013 between described filtering ponds 101 water inlet 1017 and adjacent described filtration 1014, described filtering ponds 101 are split formation Buffer Pool part 1011 and filtering ponds part 1012 by described water distributing plate 1013；Buffer Pool part 1011 is connected with subsequent filter pond part 1012 by porous water distributing plate 1013, and porous water distributing plate 1013 can play the purpose of stable flow velocity and water distribution uniformity, improves filter effect.Above-mentioned filtering ponds 101 pool wall is preferably and is built into by brick mix structure, is reinforced concrete floor at the bottom of pond.
The problem that screen plugging rear backwash is difficult or energy consumption is high existed for mechanical filter equipment in currently available technology, in the present embodiment, utilizes siphon principle to reach the Non-energy-consumption automatic back-flushing function of filtering ponds 101.Particularly as follows: every grade of above-mentioned filtration 1014 is each equipped with for it being carried out the siphon drainage mechanism of backwash when this filtration 1014 blocks；Above-mentioned siphon drainage mechanism is preferably and connects with corresponding sewage draining exit 1016, can be discharged in the lump by the dirt fallen at the bottom of pond, play the dual function of blowdown and backwash in siphon backwash drainage procedure.Such as Fig. 2, the concrete structure of above-mentioned siphon drainage mechanism is: this siphon drainage mechanism includes siphon blowing pipe 102 and siphon destructing tube 103；Described siphon blowing pipe 102 includes exterior tube 1022 and the inner tube 1021 of socket, below this externally-located pipe 1022 top, inner tube 1021 top, inner tube 1021 top rational height limits liquid level according to backwash in filtering ponds 101 set in advance and adjusts (i.e. inner tube 1021 top is concordant with the filtering ponds 101 backwash liquid level preset)；Described exterior tube 1022 bottom connects with corresponding described sewage draining exit 1016, and described inner tube 1021 bottom is connected with sewage collection equipment, and the rational height of sewage collection equipment should be less than inner tube 1021 tip height, to ensure being smoothed out of siphonage.Such as Fig. 2, time actually used, exterior tube 1022 bottom can be connected with corresponding sewage draining exit 1016 by water pipe, and inner tube 1021 bottom can be connected with corresponding sewage collection equipment by water pipe；Also exterior tube 1022 and inner tube 1021 can be respectively provided with l-shaped pipe, inner tube 1021 vertical portion passes bottom exterior tube 1022 and inserts in exterior tube 1022 vertical portion, the vertical portion of two L-type pipes is mutually socketed, and inner tube 1021 is located in the position encapsulation process in exterior tube 1022.Described siphon destructing tube 103 one end is connected with described exterior tube 1022 top, the described filtering ponds of other end insertion 101 are interior and are positioned at below default filtering ponds 101 backwash liquid level, and the rational height of siphon destructing tube 103 bottom terminates liquid level according to siphon in filtering ponds 101 set in advance and determines.For said structure, siphon blowing pipe 102 is preferably located at outside described filtering ponds 101.Certainly, siphon blowing pipe 102 also can be located in filtering ponds 101, does not disturbs with the generation that arranges filtering sieve plate 1014；Simply exterior tube 1022 bottom should not be connected with sewage draining exit 1016, but still can go deep into close to bottom, pond, and under siphon suction function, dirt also can be discharged therewith.
During use, rise to after in filtering ponds 101 set in advance, backwash limits liquid level when sieves plate 1014 blocking causes filtering (i.e. this filtration sieve plate 1014 is near the side of water inlet 1017) liquid level before sieve plate 1014, i.e. current are unrestrained rises to inner tube 1021 top end, now trigger siphon effect, start siphon blowdown, it is deposited in the dirt at the bottom of pond and discharges outside pond by siphon blowing pipe 102, and the water backflow of (i.e. this filtration sieve plate 1014 is away from the side of water inlet 1017) after promoting Partial filtration sieve plate 1014, thus realize the purpose of backwash.When in filtering ponds 101, water level is down to siphon destructing tube 103 bottom place height, air enters siphon blowing pipe 102 by siphon destructing tube 103, destroys siphonage, and in filtering ponds 101, liquid level no longer declines.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
