Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fish farming equipment, and in particular relates to indoor factory-based fish farming pond oxygenation equipment. Background Art
[0002] Oxygen content in water is a crucial indicator for aquaculture. Fish and other aquatic organisms absorb oxygen in the water to maintain respiration. Oxygen content in water is affected by factors such as temperature and water quality. Natural water bodies in the wild, due to the presence of flow or large bodies of water, contain sufficient oxygen, meeting the needs of aquatic organisms. However, fish ponds, due to their confined water bodies and limited flow, are often more sensitive to factors such as temperature and water quality, making them prone to hypoxia. Traditional fish ponds typically use aeration pumps installed in the middle of the pond. However, these pumps are noisy, energy-intensive, and inefficient, resulting in low oxygen delivery. In recent years, a trend toward indoor, factory-style fish farming has emerged, utilizing multiple fish ponds within a shed. These ponds are smaller than traditional ponds and utilize precise temperature control and well-equipped filtration systems to maintain water quality. This allows for a factory-style fish farming model and higher stocking densities. However, these indoor fish ponds are not suitable for conventional aeration pumps, which are bulky, noisy, energy-intensive, and inefficient, and thus cannot guarantee optimal operation. Utility Model Content
[0003] The purpose of this utility model is to address the problems of existing indoor aquatic fish ponds lacking good oxygenation equipment, which cannot ensure sufficient oxygen content in the water under the requirements of low power consumption and low noise, and cannot guarantee the healthy growth of aquatic products. The utility model patented indoor factory fish pond oxygenation equipment automatically draws in air and mixes water and oxygen twice, ensuring sufficient oxygen content in the water under the premise of low power consumption and low noise, so as to ensure the healthy growth of indoor aquatic products.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] An indoor factory-scale fish pond oxygenation device includes an oxygenation water pump; the outlet of the oxygenation water pump is connected to a water-gas mixing head and a water outlet nozzle in sequence; the water-gas mixing head includes an outer sleeve and a mixing core; the mixing core is matched and arranged in the outer sleeve; the mixing core includes an inlet head, an arc trough and a water outlet head connected in sequence; a plurality of water-gas mixing tubes are provided through the mixing core; an air inlet hole I is provided on the arc trough; an air inlet hole II is provided on the water-gas mixing tube; an air inlet pipe is provided on the outer sleeve; the air inlet hole I, the air inlet hole II and the air inlet pipe are matched; the space between the arc trough and the outer sleeve forms a water-gas mixing section I; the space between the oxygenation water pipe and the inner wall of the arc trough forms a water-gas mixing section II.
[0006] The aeration water pump draws water into the pool, and oxygenates it through the water-gas mixing head, and finally sprays it out through the water outlet nozzle; the water flows into the water-gas mixing pipe from the water inlet head, and the air enters from the air inlet pipe, air inlet hole I and air inlet hole II, and water and air are mixed once in the water-gas mixing section I and water-gas mixing section II respectively, so that the oxygen content in the water increases; the water mixed with small air bubbles finally enters the water outlet nozzle from the water outlet head and then flows out; the aeration water pump can adopt a silent and low-power submersible pump. Compared with the traditional aerator set up on the water surface, which generates loud noise and high energy consumption, the water pump of this patent scheme is more suitable for use in indoor fish ponds.
[0007] As a further technical improvement, the inlet of the water-gas mixing tube is located at the water inlet, and the outlet is located at the water outlet. The inlet diameter of the water-gas mixing tube is the largest, the diameter of the middle portion gradually decreases inward, and the outlet diameter is larger than the middle diameter but smaller than the inlet diameter. Because the inlet of the water-gas mixing tube is large and the outlet is small, according to Bernoulli's principle, the flow rate increases when water flows from a larger diameter tube into a smaller diameter tube. Furthermore, the diameter of the water-gas mixing tube is the smallest in the middle portion, forming a Venturi tube. This creates a negative pressure suction force at the small diameter portion of the tube in the middle, allowing gas to be drawn into the aeration pipe through the inlet, where it is fully mixed with the water and increases the oxygen content of the water.
[0008] As a further technical improvement, round balls are movable in the water-gas mixing section II.
[0009] As a further technical improvement, the ball is located between air inlet I and air inlet II; its movement space is limited to the concave portion in the middle of the water-air mixing tube. Because the arc groove is concave downward, the diameter of the water-air mixing tube is smallest in the middle, and larger at both ends than in the middle. This confines the ball to a position near the middle of the water-air mixing tube, located between air inlet I and air inlet II. Therefore, the ball can only move back and forth within the limited position between air inlet I and air inlet II and will not move out of other positions. When water flows through, it causes the ball to continuously vibrate, which can play a certain blocking role, preventing excessive water and air from entering a single air inlet II, and instead allowing it to enter multiple air inlet IIs, thus ensuring a certain degree of uniform air intake.
[0010] As a further technical improvement, a reducing sleeve is provided inside the outer sleeve; the water-gas mixing head is inserted into the reducing sleeve, and the reducing sleeve matches the water inlet head and can clamp the water inlet head.
[0011] As a further technical improvement, the two ends of the outer sleeve are respectively connected with a connecting pipe I and a connecting pipe II.
[0012] As a further technical improvement, the connecting pipe I is connected to the oxygenation water pump; the connecting pipe II is connected to the water outlet nozzle.
[0013] As a further technical improvement, a fixing seat is provided at the rear end of the oxygenation water pump.
[0014] As a further technical improvement, the fixing base is detachably connected to the inner wall of the fish pond. The fixing base is used to fix the entire device. The fixing base can be fixed to the pond wall in the form of a suction cup, or can be fixed with glass glue, etc., as long as it can be fixed in the pond. The fixing base and the entire device can be removed when the position needs to be adjusted.
[0015] How to use the above-mentioned indoor factory fish pond oxygenation equipment:
[0016] Pumping water: put the device into the fish pond and turn on the aeration pump, then the water in the fish pond is pumped into the water-gas mixing head;
[0017] Primary mixing: Water flows into the outer casing and enters the water-gas mixing pipe from the water inlet head. Since the water-gas mixing pipe has a large inlet and a small outlet, and the diameter is smallest in the middle, the water flow speed increases rapidly, and the air pressure in the water-gas mixing section I decreases. The atmosphere presses the air flow into the air inlet pipe and enters the water-gas mixing section I. Part of the water flows out from the air inlet II and the air inlet I and enters the water-gas mixing section I, where it mixes with the air flow for the first time.
[0018] Secondary mixing: Air and water after the first mixing enter each air inlet hole I and enter the water-gas mixing section II; in the water-gas mixing section II, part of the water overflows from the air inlet hole II and mixes with the gas. The gas is carried out of the water-gas mixing pipe in the form of small bubbles and ejected through the water-gas nozzle to increase the oxygen content of the water in the pool;
[0019] Uniform water vapor: In the secondary mixing step, since the round beads are movably arranged in the water vapor mixing section II, the round beads shake back and forth between the air inlet holes I and II with the water flow, which can play a certain blocking role, preventing too much water and gas from entering one of the air inlet holes II, and instead entering multiple air inlet holes II, playing a certain role in uniform air intake.
[0020] The technical solution of this utility model has the following beneficial effects:
[0021] 1. The utility model can mix air and water twice through the water-gas mixing section I and the water-gas mixing section II of the water-gas mixing head before introducing the air into the water body, so that the air can be mixed with the water flow more fully, and the oxygen content of the water in the pool is increased, which is beneficial to the healthy growth of aquatic animals such as fish.
[0022] 2. The utility model of the several water-gas mixing tubes is large at one end and small at the other end, and the diameter of the middle tube is the smallest, forming a Venturi tube, which accelerates the water flow speed and forms suction in the middle to suck air into the oxygenation water pipe, so that the air is continuously mixed with the water flow in the oxygenation water pipe to achieve the purpose of increasing the oxygen content in the water.
[0023] 3. The utility model sets round beads that can shake with the water flow in the water-gas mixing section II. On the one hand, it can block the airflow and disperse the airflow so that the gas forms multiple small bubbles. On the other hand, it can prevent too much airflow and water flow from entering one air inlet II, so that all air inlet holes II can fully obtain the water flow mixed with gas, making the oxygen content of the water body higher.

DETAILED DESCRIPTION
[0029] The present invention will be further described below with reference to the accompanying drawings.
[0030] Example 1:
[0031] like Figures 1 to 4As shown, an indoor factory-type fish pond oxygenation equipment includes an oxygenation water pump 1; the outlet of the oxygenation water pump 1 is connected to a water-gas mixing head 2 and a water outlet nozzle 3 in sequence; the water-gas mixing head 2 includes an outer sleeve 5 and a mixing core 6; the mixing core 6 is matched and arranged in the outer sleeve 5; the mixing core 6 includes an inlet head 7, an arc groove 8 and a water outlet head 9 connected in sequence; a plurality of water-gas mixing tubes 10 are provided through the mixing core 6; the arc groove 8 is provided with an air inlet hole I 11; the water-gas mixing tube 10 is provided with an air inlet hole II 13; the outer sleeve 5 is provided with an air inlet pipe 14; the air inlet hole I 11, the air inlet hole II 13 and the air inlet pipe 14 are matched with each other; the space between the arc groove 8 and the outer sleeve 5 forms a water-gas mixing section I; the space between the oxygenation water pipe 10 and the inner wall of the arc groove 8 forms a water-gas mixing section II.
[0032] The inlet of the water-gas mixing tube 10 is located on the water inlet head 7, and the outlet is located on the water outlet head 9; the inlet diameter of the water-gas mixing tube 10 is the largest, the middle diameter gradually concave inward and becomes smaller, and the outlet diameter is larger than the middle diameter but smaller than the inlet diameter.
[0033] A round ball 12 is also movably provided in the water-gas mixing section II.
[0034] The ball 12 is located between the air inlet hole I 11 and the air inlet hole II 13 ; the movement space of the ball 12 is limited to the concave portion in the middle of the water-gas mixing tube 10 .
[0035] A reducing sleeve 17 is provided in the outer sleeve 5 ; the water-gas mixing head 6 is inserted into the reducing sleeve 17 .
[0036] The method of using the utility model is as follows:
[0037] Primary mixing: Water flows into the outer casing 5 and enters the water-gas mixing pipe 10 through the water inlet head 7. Since the inlet of the water-gas mixing pipe 10 is large and the outlet is small, and the pipe diameter is smallest in the middle, the water flow speed increases rapidly, the air pressure in the water-gas mixing section I decreases, and the atmosphere presses the air flow into the air inlet pipe 14 and reaches the water-gas mixing section I. Part of the water flow overflows from the air inlet hole II 13 and the air inlet hole I 11 and enters the water-gas mixing section I, where it mixes with the air flow for the first time.
[0038] Secondary mixing: Air and water after the first mixing enter the air inlet holes I 11 and enter the water-gas mixing section II. In the water-gas mixing section II, part of the water overflows from the air inlet holes II 13 and mixes with the gas. The gas is carried out of the water-gas mixing pipe 10 in the form of small bubbles and ejected through the water-gas nozzle 3, thereby increasing the oxygen content of the water in the pool.
[0039] Uniform water vapor: In the secondary mixing step, since the round ball 12 is movably arranged in the water vapor mixing section II, the round ball shakes back and forth between the air inlet hole I11 and the air inlet hole II13 with the water flow, which can play a certain blocking role, preventing too much water and gas from entering one of the air inlet holes II13, and instead entering multiple air inlet holes II13, playing a certain role in uniform air intake.

[0047] This embodiment differs from the third embodiment in that the outer sleeve 5 is connected at both ends to a connecting pipe I 15 and a connecting pipe II 16. Connecting pipe I 15 connects to the aeration pump 1, while connecting pipe II 16 connects to the water outlet nozzle 3. A fixing base 4 is provided at the rear end of the aeration pump 1. This fixing base 4 is removably connected to the inner wall of the fish pond.
