Abstract
The utility model relates to the technical field of aquaculture, in particular to a dissolved oxygen device for aquaculture, which comprises a tube body, wherein a water inlet is formed at one end of the tube body and a water outlet is formed at the other end of the tube body. The dissolved oxygen device for aquaculture is characterized in that a throat port with small diameter is formed at the middle part of the tube body, the water inlet is communicated with the throat port through a tapered hole, the water outlet is connected with an outlet opening through a tapered expansion hole, and an air inlet is formed on the wall of the tapered expansion hole. On the basis of the physical principle of Venturi effect, the dissolved oxygen device for aquaculture, when in use, is directly connected with the water intake pipe, and low pressure can be produced due to the thinner throat port part and the increased water flow speed; and when the pressure is less than one atmospheric pressure, the air outside the tube body is pulled into the tube body through the air inlet to be mixed with the water therein, thereby increasing the oxygen content of the water inside the tube body. The dissolved oxygen device for aquaculture has the advantages of simple structure, no power consumption, low processing and use costs and fine bubble in water; greatly increases the contact area of the water body and the oxygen; improves the upward/downward convection and the leftward/rightward convection of the water body; and increases the overall content of dissolved oxygen in the aquaculture pond.
Description
Technical field:
The utility model relates to technical field of aquaculture, specifically a kind of simple in structure, aquaculture dissolving device that result of use is good.
Background technology:
As everyone knows, extensive aquaculture is the industry of new light in recent years, aquaculture is provided with cultures the pond, breed is provided with water inlet pipe and drainpipe, in order to improve the general breed pond of culture efficiency oxygen increasing equipment is arranged all, common cultivation equipment is divided into large-scale and small-sized two clocks, large-scale cultivation equipment adopts air compression aerator, air pump is generally adopted in small-sized breed, and the gas outlet of air compression aerator and air pump is connected with an end of wireway, and the other end of wireway inserts in the water of culturing the pond, to improve the amount of supporting that contains of culturing pool inner water, its less than one is that the bubble that produces is big, and bubble and water body contact area are little, and the water body dissolved oxygen amount is little; The 2nd, need extra aeration equipment, comprise air pump or air compression aerator, wireway, gas exhausting stone etc., equipment investment is big, the use cost height.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the aquaculture dissolving device that provide simple in structure, the water body dissolved oxygen amount is big, cost is low, result of use is good.
The utility model can reach by following measure:
A kind of aquaculture dissolving device, be provided with body, one end of body is a water inlet, the other end is a delivery port, it is characterized in that the body middle part is provided with the larynx hole of one section minor diameter, water inlet is connected with the larynx hole through the taper shrinkage hole, and delivery port is connected with outlet opening through the cone expansion hole, and the tube wall in cone expansion hole is provided with air admission hole.
The utility model can be provided with air inlet pipe, and air inlet pipe is connected with air admission hole, and connected mode can adopt and be threaded, and also can adopting pegs graft links to each other.
The larynx hole is isometrical hole in the utility model, and the diameter of water inlet is greater than the delivery port diameter.
The utility model utilizes the physics principle of " Venturi effect " (Venturi effect), during use, the aquaculture dissolving device directly links to each other with water inlet pipe, because larynx hole portion is thinner, water velocity improves, can produce low pressure, when pressure during less than 1 atmospheric pressure, water in can managing outer air and manage by the air admission hole pulling mixes, increase the oxygen content of water in the body, have simple in structure, not power consumption, processing and use cost are low, tiny at underwater bubble, improved the contact-making surface of water body and oxygen greatly, about the increasing water body, left and right sides convection current, the pond dissolved oxygen content is cultured in order to be increased comprehensively.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, a kind of aquaculture dissolving device, be provided with body 1, one end of body 1 is a water inlet 7, the other end is a delivery port 8, the tube wall external diameter of water inlet 7 and delivery port 8 is provided with connecting thread, also can on the tube wall internal diameter of water inlet 7 and delivery port 8, be provided with connecting thread, be connected with water pipe with convenient, above-mentioned same as the prior art, this does not give unnecessary details, body 1 middle part that is characterised in that of the present utility model is provided with the larynx hole 2 of one section minor diameter, water inlet 7 is connected with larynx hole 2 through taper shrinkage hole 3, delivery port 8 is connected with outlet opening through cone expansion hole 4, the tube wall in cone expansion hole 4 is provided with air admission hole 5, air admission hole 5 is connected with air inlet pipe 6, connected mode can adopt and be threaded, also can adopting pegs graft links to each other, in addition, larynx hole 1 is isometrical hole, and the diameter of water inlet 7 is greater than the diameter of delivery port 8, during use, the utility model is directly installed on the water inlet pipe, because larynx hole 1 is thinner, water velocity improves, can produce low pressure, when pressure during less than 1 atmospheric pressure, can mix with water in the pipe by the outer air of air admission hole 5 pulling pipes, increase the oxygen content of the interior water of body, the utlity model has simple in structure, not power consumption, processing and use cost are low, tiny at underwater bubble, improved the contact-making surface of water body and oxygen greatly, about the increasing water body, left and right sides convection current, the pond dissolved oxygen content is cultured in order to be increased comprehensively.
