Description

A kind of bait algae is cultivated and throwing device automatically

Technical field:

The invention belongs to culturing marine products equipment technical field, relate to marine automatically cultivation with the equipment, particularly a kind of bait algae that add bait algae in a kind of sea farming process and automatically cultivate and throwing device.

Background technology:

At present, it is food source that the marine cultured animals such as shellfish mainly be take specific several Micro Algaes in seawater, generally does not need to drop into bait in breeding process; As everyone knows, kind and the concentration of cultured output and sea area Micro Algae are closely related, but the abundance of Micro Algae is subject to the impact of various uncontrollable environmental factorss larger in seawater, if can add bait algae to mariculture shellfish, can significantly improve its cultivation efficiency, but have not yet to see the technology report of this kind equipment, therefore, design a kind of automatic cultivation and add the device of bait algae, fill up the blank of prior art, improve marine cultured animal output, there is very high economic benefit and social value.

Summary of the invention:

The object of the invention is to overcome the shortcoming that prior art exists, seeking design provides a kind of sea automatically to cultivate and add the device of bait algae, realize the sea of bait algae and automatically cultivate and throw in, without coal, oil and electric homenergic consumption, improve the output of marine cultured animal.

To achieve these goals, agent structure of the present invention comprises that nutritive salt hold tank, nutritive salt add pipe, micro-filtration net cage, CO ₂pressure-pot, CO ₂add pipe, Pneumatic piston pump, filtering sea and add pipe, nutritive salt and CO ₂supply pipe, bait algae culture bag, bait algae liquid add pipe, variable valve, the first check valve, the second check valve, reducing valve, photoswitch, spring, piston and the 3rd check valve; In the micro-filtration net cage of box rectangular structure, Pneumatic piston pump is installed, in Pneumatic piston pump, is fixedly shaped with spring and piston; Nutritive salt hold tank adds pipe by nutritive salt and is connected with the below pass-through type of piston in Pneumatic piston pump, and nutritive salt adds upper variable valve and the first check valve of being fixedly shaped with of pipe; Filtering sea adds pipe and affixed connection below the piston of Pneumatic piston pump, and filtering sea adds and on pipe, is shaped with the second check valve, and the first check valve and the second check valve can only be opened towards Pneumatic piston pump is unidirectional; CO ₂pressure-pot passes through CO ₂add pipe and be connected with the piston top in Pneumatic piston pump, CO ₂add on pipe and be fixedly installed reducing valve and photoswitch, photoswitch is photoresponse trip switch, controls Pneumatic piston pump and automatically moves, and sees that light opens daytime, and automatically close night, and photoswitch cuts out rear Pneumatic piston pump and quits work; The below outlet of the piston in Pneumatic piston pump is by nutritive salt and CO ₂supply pipe is communicated with bait algae culture bag, nutritive salt and CO ₂on supply pipe, be fixedly shaped with the 3rd check valve, the 3rd check valve can only be towards unidirectional the opening of bait algae culture bag, and the bait algae culture bag that plastic material is made is provided with bait algae liquid at normal level of liquid height and adds pipe.

The automatic cultivation that the present invention realizes bait algae with the concrete technology step adding is:

(1) first assembling bait algae cultivates and throwing device automatically, regulate nutritive salt to add the variable valve on pipe, making nutritive salt add-on and filtering sea add the seawater amount that pipe adds matches, the mixed-culture medium concentration that makes to enter Pneumatic piston pump reaches the grow concentration of required nutrient solution of conventional bait algae, its nutritive salt and mixed-culture medium are according to the difference of bait algae, its composition is different, is conventional commercially available prod;

(2) below Pneumatic piston pump inner carrier, fill with the nutrient solution of bait algae growth desired concn;

(3) regulate again CO ₂add the reducing valve on pipe, make CO ₂cO in pressure-pot ₂by reducing valve control pressure, make CO ₂gas enters Pneumatic piston pump;

(4) the pulling force driving pump inner carrier that the pressure of air pressure overcomes spring moves down, and under the thrust of piston, the first check valve and filtering sea that nutritive salt adds on pipe add the second closed check valve on pipe, nutritive salt and CO ₂the 3rd one-way valve opens on supply pipe, the nutritive medium in Pneumatic piston pump enters nutritive salt and CO ₂supply pipe; When piston is crossed nutritive salt and CO ₂during the mouth of pipe of supply pipe, with the CO of pressure ₂enter nutritive salt and CO ₂supply pipe, causes the air pressure of piston top to reduce, and spring pulls on piston and moves rapidly, makes the pressure decreased of piston below produce suction, under the effect of suction, and nutritive salt and CO ₂the 3rd closed check valve on supply pipe prevents nutritive medium and CO ₂refluence, the first check valve and filtering sea that nutritive salt adds on pipe add the second one-way valve opens on pipe, nutritive salt and filtering sea supplement the bottom enter piston by preset proportion, with micro-filtration net cage, filter extraneous seawater, prevent that other assorted algaes from entering;

(5) along with CO ₂gas constantly enters Pneumatic piston pump, the CO on piston top ₂gaseous tension increases gradually, promotes piston and restarts to move down, and repeats said process (4), completes seawater, nutritive salt and CO ₂automatic feeding;

(6) nutritive salt and CO ₂by nutritive salt and CO ₂supply pipe adds in bait algae culture bag, and bait algae carries out photosynthesis growth and breeding in bait algae culture bag, and along with adding of nutritive medium, algae liquid adds pipe automatic overflow from bait algae liquid and adds; Complete the automatic cultivation of bait algae and add.

Compared with prior art, it is simple in structure in the present invention, safe and reliable, easy to operate, saves manpower, and without power such as coal, oil and electricity, environmental friendliness, can be widely used in seawater animal cultivation, improves the output of marine cultured animal.
