Description
Technical field
The utility model relates to the corollary apparatus that aquaculture field is cultured the pond, specifically is the automatic adder-subtractor in a kind of circulating water culture system.
Background technology
Along with China's rapid economy development, water area ecological environment pollutes and destruction is on the rise, and the waters faces the serious threat of ecological desertification.The existing mode of production is restricted, and the closed circulation water breeding system is risen gradually in China.The industrial circulating water cultivating workshop has successively been built on ground such as China Guangdong, Sichuan, Shandong, Xinjiang, Fujian at present.The circulating water system water treating equipment have guaranteed fish reproduction to water quality requirement, have realized the water body repeated use, and it is low to have the water resources requirement, to advantage such as a little less than the water environment dependency.The pH value realizes its automatic development trend that is inevitable of controlling as one of water-quality guideline important in the aquaculture system.
The too high or too low culturing fish and shrimp that all influences of pH is grown.The pH value is low excessively, the pH value of culturing in fish, the shrimp blood is descended, weaken its blood oxygen carrying capability, although the dissolved oxygen in the water is higher, still to cause fish, shrimp physiology anoxia, often raise the nose above water to breathe, and growth retardation or ill, the pH value is too high then may corrode fishes and shrimps gill portion tissue, makes fishes and shrimps etc. lose respiration capability and large quantities of death.
Fish excrement, biofiltration etc. usually cause the water pH value slant acidity in the modern circulating water cultivation, need to add in the suitable alkaline matter and acidity, are controlled between the reasonable range to reach pH.The problem that existing cultivation water pH control method mainly exists is:
1, traditionally add alkaline matter by solenoid control and can't regulate flow, though also can change change pH values, main still at Steel Plant of factory, waste water water body amounts such as sewage disposal can not increase, under the situation that the water body composition can not change;
2, artificial regulatory mainly is divided into throwing alkali, changes water.Throw the alkali method only by rule of thumb, error is big, sharpness of regulation is difficult to control; Circulating water cultivation is controlled the pH value by changing water, and water consumption is big, and water resources consumption is big;
3, the pH value could be regulated after needing to measure, and control lag influences the growth of aquaculture organism;
4, existing method is intermittent the adjusting, if carry out high-precision adjusting, necessary frequent starting causes structure deteriorate too fast;
5, the method for using now mainly is that potential of hydrogen is regulated simultaneously, promptly acid the mistake just adds alkali by force, otherwise add acid, this method can't be used in the circulating water cultivation environment, the variation of pH value can badly influence the environment of aquaculture organism, adjusting can cause fish kill repeatedly, also can cause the death of the microorganism of evolution water body in the system simultaneously.
Along with the fast development of aquaculture, above defective presses for and overcomes, solves.
Summary of the invention
The purpose of this utility model is to overcome above shortcoming, and the automatic adder-subtractor in a kind of circulating water culture system is provided.
The purpose of this utility model is achieved by following structure.
Automatic adder-subtractor in a kind of circulating water culture system is characterized in that:
Insert the pH transmitter in culturing the pond, the pH transmitter is connected to industrial computer by electrical control cabinet, and industrial computer connects volume pump by electrical control cabinet, the output flow of control volume pump;
The input terminus of volume pump connects the sodium hydrogen carbonate solution jar, and the metering delivery side of pump is connected to equalizing tank by pipeline;
Culture the water outlet in pond and deliver to water correction plant by pipeline, the water after water treating equipment are handled is connected to equalizing tank by pipeline, and the water after the mixed adjusting of equalizing tank is sent back to and cultured the pond.
Further, the water outlet in described breed pond is positioned at the sidewall of culturing the pond.
Adopt the technical solution of the utility model, press foregoing description and connect configuration, during use, the pH value signal of pH transmitter is inputed to industrial computer, industrial computer compares the setting data of signal with inside, analysis and judgement is cultured the variation in pond, the pH value of aquaculture water is maintained near the set(ting)value ± 0.3 scope in, as requested, control volume pump flow makes volume pump that suitable sodium hydrogen carbonate solution is added to equalizing tank, simultaneously, culture the pond and carry out water after the filtration treatment and deliver in the equalizing tank and mixes, send back to again and culture the pond with sodium hydrogen carbonate solution, make water in the circulating water cultivation pond maintain to be provided with pH value neighbouring ± be able to recycle on 0.3 the interior basis of scope.
The pH value of the water body that the utility model collects by the pH transmitter is handled calling program can be identified, judge with reference to the value of setting whether the pH value satisfies the needs of system then, and in conjunction with the Changing Pattern of historical pH and throw and raise, change the water time and give suitable output valve of volume pump, thereby the pH of control total system changes.
Advantage of the present utility model and beneficial effect:
1. present method is primarily aimed at the circulating water cultivation environment, not only adds alkali automatically, has also saved water resources;
2. the only single alkali that adds of present method is regulated, because the cultivating system water body only can change toward the slightly acidic direction, so do not need to add acid, makes pH value in the system maintain the environment of suitable growth always, and is with strong points, reduces and avoided the unnecessary sour operation that adds;
3. present method is continuous adjusting, and regulate process does not have and stops, thus can be in a small scope with the pH value stabilization of water body, and keep the volume pump long term operation, reduced loss, the damage of equipment.
4. operating process such as water, blowdown are raised, added to present method at throwing commonly used in the cultivating system, can judge automatically and regulate;
5. the utility model carries out continuously uninterrupted the adjusting at circulating water culture system, the pH value of water body is remained on a stationary value help biological growth numerical value; The water body environment of regulating is a mobile, water pH value is changed to prejudge add alkali number and make control;
6. the utility model is monitored cultivation water pH in real time and is changed, and judges automatically, the pH value of aquaculture water is maintained near the set(ting)value ± 0.3 scope in, solved precision control problem;
7. the pH on-line monitoring has solved and can't monitor in real time, and dynamic auto adjusting pH value has realized that pH effectively controls near the narrow range of breed optimum value, has solved the big problem of aquaculture water fluctuation.
8. the utility model replaces traditional magnetic valve mode with volume pump, has remedied the shortcoming that the magnetic valve of traditional method can't accurate flow adjustment; By with being used in combination of online water quality monitoring system, order remotely changing flow under running status according to program, more can reach lasting the adjusting and make water pH value remain near the interior effect of the small scope of set(ting)value, for industrial circulating water cultivating provides effective guarantee.
Above advantage is that prior art is not available, has demonstrated fully outstanding effect and significant advantage that the utility model brings, and very big marketing prospect and value are arranged.
