Description
Technical field
The utility model relates to a kind of aquaculture collection dirt, discharging pollution apparatus structure, particularly relates to jetting type circulative convection blowdown cultivator.
Background technology
Prawn culturing is that significant contribution has been made in China's sea fishery economic development.In recent years, rapidly, cultured area and output are all at the forefront in the world for China's shrimp culture industry development.While scoring achievements, the pollution of shrimp farming self is also more and more serious.These pollutions are from the residual bait of feeding and prawn metabolite, if the same water body of Long-Time Service impacts safely water body certainly.But a lot of raiser is almost just directly discharge without any process to aquaculture wastewater for prawns again.Its consequence pollutes local marine site, destroys the coastal ecological balance, cause culture zone to occur the popular of large area prawn disease, coastally also occurs red tide phenomenon, the development of serious threat shrimp farming.Therefore, solving the problem of aquaculture wastewater process in the urgent need to a kind of effective and continuable scientific method, remove residual bait and prawn metabolite in pond in time, is the important measures keeping pool inner water body safety.
At present, the shrimp pond sewage water treatment method of China mainly adopts biology, chemistry to decompose, precipitates dirt, but the method process cost that is complicated and cost is higher, uneconomical impracticable, therefore can not extensively popularize.Also there are some state-of-the-art technologies to be adopt physical method, utilize hydrodynamic force driving principle to achieve not need the system of adding any biochemical pharmacology and just automatically can collect dirt, discharging pollution.The utility application of prior art as application publication number CN 102893944 A discloses a kind of cultivating system of automatic pollution discharge, comprise culturing pool, funnel type sewage sump, " L " type blow-off pipe, blowdown control device, receive dirty basket, dirt discharge groove, blow-off pipe, water level control pipe and push away water device, automatic control of sewage disposal valve is arranged to by blowdown control device of the present utility model, can according to throw something and feed number of times setting blowdown number of times and the blowing time of cultivated animals, after certain hour that cultivated animals is thrown something and fed, residual bait in culturing pool, ight soil, spoils etc. gather in funnel type sewage sump under the current of annularly flow, eliminating dirt opened automatically by automatic control of sewage disposal valve, avoid because of residual bait, ight soil, spoils etc. are to the pollution of breeding water body, reduce the probability that aquatic animal disease breaks out.But it is embodied as originally higher, and larger to taking of breeding water body.
Summary of the invention
The purpose of this utility model is that providing a kind of for prior art does not need to add any biochemical pharmacology and can utilize that fluid mechanics principle realizes automatically collecting dirt, discharging pollution, water body takies little, cost-saving synergistic, protecting ecology jetting type circulative convection blowdown cultivator yet.
The utility model solves the problems of the technologies described above adopted technical scheme: jetting type circulative convection blowdown cultivator, comprises the tank with funnel type bottom surface, wherein: sink center is provided with the bearing of taper; Rest base is provided with the screen pack matched with the sewage draining exit bead of tank; The side of bearing has the inlet opening run through; Holder top has centre pipe; The upper side of centre pipe has radiant type jet orifice; Reverse propeller is provided with inside centre pipe.Reverse propeller, under the driving of drive motors, along centre pipe formation current upwards, outwards penetrates current at the radiant type jet orifice through top.Bottom of gullet forms flow compensated and drives residual bait and ight soil to center convergence, and Action of Gravity Field makes it to fall into sewage draining exit through filter screen, and thus Zhi Xu center arranges centre pipe and takies water body less.By said structure, make this device not need to use chemicals just can remove residual bait and ight soil, effectively reduce quantity of exchanged water, and this device simple structure, with low cost, there is the advantage of cost-saving synergistic, ecology close friend.
For optimizing technique scheme, the measure taked also comprises: sink center is provided with the bearing of taper; Rest base is provided with the screen pack matched with the sewage draining exit bead of tank; The side of bearing has the inlet opening run through; Holder top has centre pipe; The upper side of centre pipe has radiant type jet orifice; Reverse propeller is provided with inside centre pipe.Reverse propeller, under the driving of drive motors, along centre pipe formation current upwards, outwards penetrates current at the radiant type jet orifice through top.Bottom of gullet forms flow compensated and drives residual bait and ight soil to center convergence, and Action of Gravity Field makes it to fall into sewage draining exit through filter screen, and thus Zhi Xu center arranges centre pipe and takies water body less.By said structure, make this device not need to use chemicals just can remove residual bait and ight soil, effectively reduce quantity of exchanged water, and this device simple structure, with low cost, there is the advantage of cost-saving synergistic, ecology close friend.Reverse propeller is connected with the drive motors being arranged on centre pipe top through extension rod.Centre pipe top seal.Centre pipe top seal can make Reverse propeller extrusion fluid, forms current more at a high speed, have more useful effect at radiant type jet orifice place.Specifically top seal bearing can be set.
Because the utility model have employed the bearing that sink center is provided with taper; Rest base is provided with the screen pack matched with the sewage draining exit bead of tank; The side of bearing has the inlet opening run through; Holder top has centre pipe; The upper side of centre pipe has radiant type jet orifice; Reverse propeller is provided with inside centre pipe.Reverse propeller, under the driving of drive motors, along centre pipe formation current upwards, outwards penetrates current at the radiant type jet orifice through top.Bottom of gullet forms flow compensated and drives residual bait and ight soil to center convergence, and Action of Gravity Field makes it to fall into sewage draining exit through filter screen, and thus Zhi Xu center arranges centre pipe and takies water body less.By said structure, make this device not need to use chemicals just can remove residual bait and ight soil, effectively reduce quantity of exchanged water, and this device simple structure, with low cost, there is the advantage of cost-saving synergistic, ecology close friend.Thus the utility model has does not need to add any biochemical pharmacology and also can utilize that fluid mechanics principle realizes automatically collecting dirt, discharging pollution, water body takies little, cost-saving synergistic, protecting ecology advantage.
