Description

A fish culture aeration device

Technical field

The invention relates to the field of fish pond aeration equipment, in particular to a fish culture aeration device and a using method thereof.

Background technique

In the field of fish pond farming, oxygen aerators are often used to aerate fish ponds, such as the common water spray aerators, which operate on the principle that the water spray aerator is installed in the center of the fish pond. The water is pumped into the sprinkler and then ejected into the air, thereby increasing the contact area between the air and the water, so that excessive carbon dioxide in the water body and high dissolved oxygen in the air enter the water body, and at the same time, the upper dissolved oxygen is saturated. After the water body flips into the lower water body, the water in the fish pond dissolves more oxygen as much as possible, avoiding the decline of the body due to lack of oxygen, and even causing a large area of death.

The existing water spray aerator has the following problems: (1) The water spray aerator has higher use cost, higher power consumption, and relatively higher input cost for farmers; (2) water spray aeration The water spray range is limited, and the density distribution of dissolved oxygen in the water in the fish pond cannot be more uniform, resulting in a large amount of fish gathering around the water spray aerator, while the water in other places is less fish, due to limited space and volume. Large fish occupy most of the oxygen-rich waters, while other smaller fish do not get enough oxygen in time to suffer from anorexia, slow movement, decreased resistance, etc., which causes these fish to grow slowly and become prone to illness. Death, causing losses to farmers.

The method for using the fish culture aeration device of the present invention comprises the following steps:

Step 1. Prepare an aeration device to empty the impurities in the aerobic body and the liquid thereof, and insert the third storage chamber as a bottom through the cutting portion and the fixing portion to insert the aerator device vertically at the bottom of the fish pond, and increase the chain through the chain. The oxygen device is connected to the rotating device disposed on the edge of the fish pond, wherein the water inlet hole of the first receiving chamber is not higher than the water surface of the fish pond and the water hole is sealed first, and the upper portion of the first receiving chamber is exposed to the water surface. The outlet end of the two-way pipe is higher than the water surface;

Step 4. Repeat

steps

2 and 3 to achieve a continuous water spray effect.

Taking a single oxygenator as an example, the operation principle of the aeration device of the present invention is: at the beginning, the three accommodation chambers of the oxygenator are all air; then, through the water inlet hole in the upper portion of the first storage chamber, the first accommodation chamber is Loading water, at this time, the water in the first accommodating chamber is discharged into the third accommodating chamber through the first through pipe, and the air in the third accommodating chamber is squeezed through the third through pipe into the second accommodating chamber, and the second accommodating chamber will enter The air is discharged through the second through pipe; after the water in the third receiving chamber reaches a predetermined height (generally the third receiving chamber is not filled with water), the water supply to the third receiving chamber is stopped, and then the whole oxygenator is inverted by 180°. The third receiving chamber is placed at the top. At this time, the third receiving chamber is filled with water into the second receiving chamber through the third connecting tube, and the air in the second receiving chamber is squeezed and discharged to the third receiving chamber through the third connecting tube. After entering the air; after the third receiving chamber no longer supplies water to the second receiving chamber, the second receiving chamber is not filled with water at this time, and the first receiving chamber is filled with water because it is completely placed in the water; The oxygen body is rotated 180° to return it to the initial position At this time, the first extending portion of the third through pipe discharges the excess water in the second receiving chamber to the third receiving chamber, so that the water level in the second receiving chamber is not higher than the first extending portion, due to the first receiving portion The room is filled with water, and the first receiving chamber again feeds water into the third receiving chamber through the first through pipe, and the air in the third receiving chamber is again squeezed to discharge air into the second receiving chamber through the third through pipe, thereby making the first The water in the two accommodating chambers is squeezed and discharged through the second through pipe, thereby forming water spray until the water level in the second accommodating chamber is lower than the height of the connecting hole at the junction of the second accommodating chamber and the second connecting pipe, and then The above method is repeated again, and after the second storage chamber is again obtained with a sufficient amount of water, the water spray is again formed to form a cycle in which water and air are mutually fused. Compared with the existing water spray aerator, the aeration device of the present invention only needs power when flipping the oxygenator, but does not need it when spraying water. Obviously, the invention consumes very little energy. The earth reduces the consumption of energy, which in turn reduces the cost of the farmers; in the spraying time, as long as the capacity of the second and third holding chambers is large enough, a spray can obtain a longer water spray. The time for the second storage chamber to refill the water is relatively short and negligible, and as a result, the effect of continuous water spray can be achieved as a whole.

As a modification of the present invention, although the single aerator body of the present invention covers a relatively narrow water area, if a plurality of oxygenators are connected in series to form a row structure, the water of the same row of oxygenators can be made. A relatively uniform amount of dissolved oxygen can be obtained, that is, the two sets of the oxygenators are formed into an aerobic group, and the aeration device includes at least one aerobic group, and each of the aerobic groups is symmetrically arranged between the oxygenators. And one of the oxygenators is inverted by 180°. When each group of oxygenators is inverted with each other, continuous uninterrupted water spray can be realized, even if water is refilled in the second storage chamber of an aerator, the water in the fish pond will not be stopped. Both can obtain sufficient water of breathing oxygen, greatly increase the contact area of water and air, increase the amount of dissolved oxygen, and at the same time, in the same row, each flip of the oxygenator can flip the upper and lower layers of the water body. , the upper layer of the oxygen-rich water body is caused to flow to the lower layer, and the lower layer of the oxygen-poor water body is turned to the upper layer to dissolve the oxygen, thereby further increasing the dissolved oxygen amount of the water body, compared to the water spray type aerator, the invention has The oxygenation equipment of the row structure obviously has an advantage in the dissolved oxygen effect, and there is no case where the fish concentrates to absorb oxygen in one place. As for the cost problem, since the structure of the aeration device of the present invention is relatively simple, it is not required. For more complicated mechanical structures, the oxygen-enriching body can be made of low-cost materials such as polymer, bamboo, and wood, and the overall manufacturing cost is not high. Therefore, the input cost of the farmers is not high.

In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: by providing an oxygen-enhancing body, the principle of mutually squeezing water and air in a confined space is used to achieve the effect of continuous water spray, and the increase is greatly reduced. The energy consumption of the oxygen equipment greatly reduces the user's use cost. At the same time, by setting the oxygenators in a row structure, the dissolved oxygen density distribution of the whole water area can be more uniform, effectively increasing the dissolution of the water body. The amount of oxygen allows the fish in the water to obtain a sufficient amount of oxygen, reducing the incidence of fish sickness and death.

The above method of using the aquaculture aeration device includes the following steps:

Step 1. Prepare an aeration device, empty the impurities in the oxygenator 1 and the liquid thereof, and insert the third storage chamber 4 as a bottom through the cutting portion 801 and the fixing portion 1101 to insert the aerator device vertically at the bottom of the fish pond. And connecting the aeration device to the rotating device disposed on the edge of the fish pond through the chain, as shown in FIG. 2, wherein the water inlet hole of the first receiving chamber 2 is required to be no higher than the water surface of the fish pond and sealed into the water first. a hole, an upper portion of the first accommodating chamber 2 is exposed to the water surface, and an outlet end of the second through pipe 6 is higher than a water surface;

At this time, the water passing time can be obtained by the calculation formula of the flow rate and the volume, thereby controlling the height of the water level in the third receiving chamber 4)

After step 3 and step 2 are completed, the aeration device is inverted 180° to return it to the initial position. After waiting for a certain time, the water in the second storage chamber 3 can be sprayed through the second through pipe 6 until the water is sprayed. The predetermined water spray time is reached (the spray time can be obtained by the calculation formula of flow rate and volume);

Step 4. Repeat steps 2 and 3 to achieve a continuous water spray effect.

In the above method of use, the calculation formula of the flow rate and the volume is: 1, Q × t = V; 2, v × A = Q. Where Q is the flow rate, t is the water flow time or the water spray time, V is the volume, v is the average flow rate of the pipe, and A is the pipe cross-sectional area.

The operating principle of the aerator of the aeration device of the present invention is: at the beginning, the three accommodation chambers of the oxygenator 1 are air; and then the first storage chamber 2 is installed through the water inlet hole in the upper portion of the first storage chamber 2. Water, at this time, the water in the first accommodating chamber 2 is discharged into the third accommodating chamber 4 through the first through pipe 5, and the air in the third accommodating chamber 4 is pressed through the third through pipe 7 into the second accommodating chamber. 3, the second accommodating chamber 3 discharges the incoming air through the second through pipe 6; after the water in the third accommodating chamber 4 reaches a predetermined height (generally the third accommodating chamber 4 is not filled with water), stops to the third Water is added to the accommodating chamber 4, and then the entire oxygen absorbing body 1 is inverted by 180°, so that the third accommodating chamber 4 is placed at the top. At this time, the third accommodating chamber 4 is filled into the second accommodating chamber 3 through the third through tube 7. The air in the second accommodating chamber 3 is squeezed to discharge air into the third accommodating chamber 4 through the third through pipe 7; after the third accommodating chamber 4 no longer supplies water into the second accommodating chamber 3, this When the second accommodating chamber 3 is not filled with water, the first accommodating chamber 2 is filled with water because it is completely placed in the water; then the oxygenator is rotated by 180° to make it back In the initial position, at this time, the first extending portion 701 of the third through pipe 7 discharges excess water in the second accommodating chamber 3 to the third accommodating chamber 4, so that the water level in the second accommodating chamber 3 is not higher than the first In the insertion portion 701, since the first storage chamber 2 is filled with water, the first storage chamber 2 again enters the third storage chamber 4 through the first through-tube 5, and the air in the third storage chamber 4 is again squeezed. The air is discharged to the second accommodating chamber 3 through the third through pipe 7, and the water in the second accommodating chamber 3 is squeezed and discharged through the second through pipe 6, thereby forming water spray until the second accommodating The water level in the chamber 3 is lower than the height of the connection hole at the junction of the second storage chamber 3 and the second communication tube 6, and then the above method is repeated again, so that the second storage chamber 3 obtains a sufficient amount of water again, and then the water spray is formed again. Form a cycle in which water and air run against each other. Compared with the existing water spray aerator, the aeration device of the present invention only needs power when flipping the aerator 1 and does not need it when spraying water. Obviously, the invention consumes very little energy. The energy consumption is greatly reduced, thereby reducing the use cost of the farmer; in the water spray time, as long as the capacity of the second storage chamber 3 and the third storage chamber 4 is sufficiently large, one spray can be obtained longer. The water spray time, while the second storage chamber 3 is again filled with water for a relatively short period of time, negligible, thereby achieving the effect of continuous water spray as a whole.

As an improved embodiment, a plurality of oxygenators are connected in series to form a bank structure, so that a relatively uniform amount of dissolved oxygen can be obtained in the water of the same row of oxygenators 1, that is, the oxygenators 1 For a group to form an aerobic group, the aeration device comprises at least one aerobic group, and in each aerobic group, the oxygenators 1 are symmetrically arranged and one of the oxygenators is inverted by 180°. When each group of oxygenators 1 is inverted with each other, continuous uninterrupted water spray can be realized, and even when water is recharged to the second storage chamber 3 of an aerator 1, the water spray is not stopped. The fish can obtain enough water for breathing oxygen, greatly increase the contact area between the water and the air, increase the dissolved oxygen amount, and at the same time, in the same row, each flip of the oxygenator 1 can be applied to the water body. The upper and lower layers are flipped to cause the upper oxygen-rich water to flow to the lower layer, and the lower oxygen-poor water body is flipped to the upper layer to dissolve oxygen, thereby further increasing the dissolved oxygen content of the water body, compared to the water spray aerator. The aeration equipment with the townhouse structure is obviously dominant in the dissolved oxygen effect, and there is no case where the fish concentrates on oxygen in one place.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention.
