Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The timer (model is TPG-110), the PLC (model is FX3GA-60MR-CM) and the water pump (model is 50ZW10-20) mentioned in the utility model can be obtained by ordering in the market or private

Please refer to fig. 1-3, an automatic blowdown system for aquaculture, comprises an aquaculture pond 1 and a sewage pond 2, one side of the sewage pond 2 is connected with a blowdown pipe 3 extending to the interior of the aquaculture pond 1, both ends of the blowdown pipe 3 are respectively provided with a water inlet 4 and a water outlet 5, the outer side of the blowdown pipe 3 is provided with a sleeve 6, the bottom end of the sleeve 6 is provided with an anti-escape net 7, the bottom end of the anti-escape net 7 is provided with a fixing seat 8, one side of the sleeve 6 is connected with an air duct 9, the air duct 9 is communicated with the sleeve 6 through an air inlet 10, and one end of the air duct far away from the air inlet 10 is.

This kind of automatic sewage disposal system of aquaculture is through at blow off pipe 3, under the cooperation of sleeve pipe 6 and air duct 9, realize the automatic blow off water of breeding pond 1, also can maintain the water level in breeding pond 1 all the time under the condition that does not have artificial intervention between the gas outlet 11 of the water inlet 4 of blow off pipe 3 and air duct 9, make the condition that pond overflow or pond by the evacuation can never appear in breeding pond 1, water in breeding pond must be through preventing escaping net 7 and just can get into blow off pipe 3, prevent escaping net 7 and be in the bottom of breeding pond 1, and the bottom of breeding pond 1 is the district that gathers of all kinds of solid state pollutants, consequently, can discharge the sewage that the pollutant concentration of breeding pond 1 bottom is the highest, and the investment is few, it is fast to take effect, the practicality is higher.

Please refer to fig. 3, the fixing base 8 is connected to the inner wall of the bottom end of the cultivation pool 1 by a screw thread, and the cultivation pool 1 is provided with a column 12 inside, and the air duct 9 is connected to the column 12 by a hoop.

This kind of automatic blowdown system of aquaculture is through fixed the fixing base with the bottom in breed pond 1, also can weld fixing base 8 and breed pond 1 or pour, fixes air duct 9 through stand 12 and the staple bolt that sets up.

Please refer to fig. 3, the water inlet 4 is located inside the culture pond 1, the culture pond 1 is located above the sewage tank 2, the air inlet 10 is located above the water inlet 4, the air outlet 11 is located below the water inlet 4, and one end of the air duct 9 close to the air outlet 11 is provided with a valve.

This kind of automatic blowdown system of aquaculture is water earlier to spill over gas outlet 11 of air duct 9 when the blowdown, continue the water injection to water spill over the water inlet 4 of blow off pipe 3, water this moment is because self gravity flows into in sewage tank 2 from blow off pipe 3, produce the filth suction blow off pipe 3 internal discharge of siphon 1 bottom in with the breed pond, the liquid level descends to gas outlet 11 and exposes in the air, the siphon is inefficacy, realize automatic blowdown, if after water spills over gas outlet 11 of air duct 9, close the valve, water stops the water injection when water spills over the water inlet 4 of blow off pipe 3, then can be with the whole discharges of water in the breed pond 1.

Please refer to fig. 2, the aperture of the escape-proof net 7 is smaller than the diameter of the released fry.

This kind of automatic blowdown system of aquaculture avoids the fry to escape from blow off pipe 3 through the net 7 that prevents escaping that sets up, and filth accessible such as fish excrement and urine, fodder impurity prevents escaping net 7 and gets into and discharge in blow off pipe 3.

The working principle is as follows: in the normal culture stage, the water level in the culture pond 1 is between the water inlet 4 of the sewage discharge pipe 3 and the air outlet 11 of the air guide pipe 9, when the water quality in the culture pond 1 is deteriorated, water is injected into the culture pond 1, the timer and the PLC controller can control the water pump to inject water at regular time, when the timer reaches a specified time value, a signal is transmitted to the PLC controller, the PLC controller controls the water pump to start to inject water into the culture pond 1, automatic timing water injection is realized, the labor intensity is reduced, water firstly flows over the air outlet 11 of the air guide pipe 9 and continuously injects water until the water flows over the water inlet 4 of the sewage discharge pipe 3, at the moment, the water flows into the sewage discharge pipe 2 from the sewage discharge pipe 3 due to the self gravity, siphoning is generated to suck the sewage at the bottom of the culture pond 1 into the sewage discharge pipe 3 to discharge, the escape-proof net 7 prevents fish fry from escaping from the sewage discharge pipe 3, and the fish feces, feed impurities and the like can, the liquid level descends to the air outlet 11 and is exposed in the air, siphon is invalid, the water level of water injection is continuously raised, automatic pollution discharge is realized through the reciprocating circulation, the water level in the culture pond 1 can be always maintained between the water inlet 4 of the sewage discharge pipe 3 and the air outlet 11 of the air guide pipe 9 under the condition without manual intervention, the condition that the pond overflows or the pond is emptied can never occur in the culture pond 1, if water overflows after the air outlet 11 of the air guide pipe 9, the valve is closed, water injection is stopped when the water overflows the water inlet 4 of the sewage discharge pipe 3, and then the water in the culture pond 1 can be completely discharged.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
