Description

Technical Field

[0001] The invention relates to the technical field of fish breeding, in particular to a fast self-cleaning fish barrel breeding pond. Background Art

[0002] At present, artificial fish breeding is mainly based on natural stocking in fish ponds. The fish density cannot be too high. For example, in a fish pond of about 110 square meters, the fish density cannot exceed 1,000 kilograms. Otherwise, the natural water environment of the fish pond cannot absorb the pollutants produced by farmed fish, such as excessive fish excrement, secretions and excess feed containing a large amount of nitrogen compounds and phosphorus compounds. Nitrogen compounds include ammonia, urea, trimethylamine, creatine, creatine ligand, protein, etc. Phosphorus compounds include inorganic phosphorus and organic phosphorus. These organic pollutants consume most of the oxygen in the water during the degradation and absorption process in the fish pond water, which will cause insufficient oxygen supply in the fish pond water, excessive ammonia nitrogen and nitrite nitrogen in the water, and serious deterioration of water quality, which will cause farmed fish to die of hypoxia, poisoning, decreased immunity, and various diseases. Fish ponds in the prior art are mostly fish farming tank pools dug out of the ground. The farming environment is greatly affected by the local natural environment and has many uncertain factors. Therefore, the cost of food safety supervision of aquatic products is high. At the same time, the earthwork workload of digging fish ponds is large and the cost is high. In addition, most of the aquaculture wastewater is discharged into the surrounding rivers without treatment, polluting the environment and water resources.

[0003] In the prior art, in order to ensure the healthy growth of high-density farmed fish, it is usually necessary to set up sedimentation tanks, filter tanks or filter machines in the circulating water loop of the fish tank breeding pond to ensure the water quality of high-density breeding water. However, it is often necessary to build large-capacity sedimentation tanks and filter tanks, and purchase filter machines and other equipment. The construction cost is too high, which makes it unaffordable for farmers. In addition, simply setting up sedimentation tanks, filter tanks or filter machines and other equipment still has limited effect on purifying the breeding water, because the excrement, secretions and excess feed of the fish stay in the sedimentation tanks, filter tanks or filter machines and other equipment in the circulating water loop for a long time, and more organic pollution waste is dissolved into the water, or converted into water-soluble organic pollution, which deteriorates the water quality of the breeding water, which will restrict the breeding density of fish and increase production costs.

[0004] Traditional fish tanks are generally round or square. The bottom of the fish tank is set as an inclined surface and a drainage hole and a drainage pipe are set at a lower position. A valve is set on the drainage pipe. The solid particle waste in the fish tank is naturally settled and gathered at the bottom of the fish tank. After reaching a certain amount, the valve of the drainage pipe is opened regularly to discharge the solid particle waste. The valve on the drainage pipe adjusts the drainage flow rate by narrowing the cross section of the drainage pipe to increase the drainage resistance. However, such an adjustment is easy to cause solid particle waste to block the narrow cross section when dealing with the discharge of particulate matter concentrate. Therefore, the drainage pipe needs a larger cross-sectional area. When discharging sewage, a large amount of water is needed to flush and take away the solid particle waste at the bottom of the fish tank. The solid particle waste in the discharged sewage is less concentrated. The discharged sewage cannot be discharged continuously for a long time, otherwise it will discharge most of the aquaculture water, wasting a lot of water resources. At the same time, solid particle wastes such as fish excrement, secretions and excess feed in traditional fish farming tank ponds stay in the fish farming tank ponds for a long time. The conversion of solid particle wastes into water-soluble pollutants in the water body will greatly increase the difficulty of purifying the farming water body and greatly increase the cost of purifying the farming water body. For example, it is necessary to build a larger volume filter pool, a larger capacity filtering machinery and equipment, consume more medicine and electricity, and require a longer time to purify the farming water body.

[0005] Therefore, it is urgent to design a low-cost, self-cleaning fish farming tank pond for the water in the pond. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the existing defects and provide a fast self-cleaning fish barrel breeding pond, which can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fast self-cleaning fish barrel breeding pond, comprising a fish barrel pond, the fish barrel pond comprising a cylindrical barrel body and an inverted conical barrel bottom, a sewage pipe is arranged at the bottom of the inverted conical barrel bottom, a discharge water pipe is arranged at the lower part of the cylindrical barrel body, a plurality of water push pipes are arranged on the outside of the fish barrel pond, the bottom of the water push pipes is connected to an external water inlet pipe, a sewage siphon device is arranged in the middle of the fish barrel pond, and an opening is arranged at the bottom center of the inverted conical barrel bottom.

[0008] Furthermore, the sewage siphon device includes a siphon channel, an air pressure regulating chamber and an air pressure regulating valve. The siphon channel consists of an inner tube, an outer tube and a top cover. The inner tube is arranged in the middle of the outer tube, and the top of the outer tube is flush with the top of the fish tank pond. The air pressure regulating chamber is arranged between the top of the inner tube and the top of the outer tube. The top of the outer tube is provided with a top cover, and the upper end of the top of the top cover is provided with a through hole and an air pressure regulating valve. One end of the air pressure regulating valve is connected to the through hole, and the other end is connected to the outside air. A base frame is provided at the bottom of the outer tube, and the base frame is arranged above the bottom center of the inverted conical barrel bottom. The lower part of the inner tube passes through the opening to connect to the sewage pipe.

[0009] Siphon is a physical phenomenon in which liquid flows from the end with a higher liquid level to the end with a lower liquid level due to pressure difference in a closed channel. The siphon flow rate is generally regulated by setting a valve in the siphon pipe to adjust the cross-section of the siphon pipe to increase the water flow resistance and adjust the flow rate, but it is easy to cause solid particle waste to block the narrow cross-section of the channel.

[0010] The sewage siphon device for fish barrel culture pond of the present invention is provided with a siphon channel, and an air pressure regulating chamber and an air pressure regulating valve are provided at the top of the siphon channel to adjust the siphon flow rate. When the siphon device is working, the solid particle waste concentrated pollutant liquid flow at the bottom of the fish barrel culture pond enters the siphon channel between the inner tube and the outer tube under the pressure of the high liquid level of the fish barrel culture pond, and the liquid flow passes through the transition point of the inner tube and the outer tube, that is, the air pressure regulating chamber, and flows to the inside of the inner tube under the action of gravity, and then leads to the sewage pipe for discharge. In the process of the solid particle waste concentrated pollutant liquid flow flowing through the siphon channel, negative pressure is generated in the siphon channel, and an air pressure regulating chamber is provided in the siphon channel to centrally reflect and regulate the pressure in the siphon channel, and the air pressure regulating chamber is connected to the air pressure regulating valve, and the external air pressure is introduced through the air pressure regulating valve, and the negative pressure in the air pressure regulating chamber is adjusted by adjusting the opening of the air pressure regulating valve, and the flow rate of the solid particle waste concentrated pollutant liquid flow is changed and regulated by adjusting the negative pressure in the air pressure regulating chamber.

[0011] The design of the sewage siphon device does not require changing the cross-sectional area of ​​the siphon channel when adjusting the flow rate of the siphon liquid. It can continuously use a smaller water flow rate to concentrate the pollutant liquid flow at a speed close to real time, quickly separating fish feces and remaining feed from the aquaculture water, greatly reducing the conversion of solid organic pollutants into water-soluble pollutants in the aquaculture water.

[0012] Furthermore, the bottom of the inverted conical barrel bottom is a disc.

[0013] Furthermore, the base frame includes a bottom disc and a bottom disc support frame, and the diameter of the bottom disc is less than or equal to the diameter of the disc.

[0014] Furthermore, the water push pipe includes a straight pipe and an oblique water outlet pipe, the straight pipe and the oblique water outlet pipe are connected through elbow 1 and elbow 2, and a ball valve 1 is arranged between elbow 1 and elbow 2.

[0015] Furthermore, the water push pipe is arranged every 0.6 to 1 meter along the length of the arc edge of the fish barrel pond, and 3 to 10 water push pipes are arranged according to the size of the fish barrel pond.

[0016] Furthermore, the angle between the inclined outlet pipe and the water surface of the fish tank pond is 45 degrees to 60 degrees.

[0017] Furthermore, the outlet of the inclined water outlet pipe is set between 30 cm above the water surface of the fish barrel pond and 50 cm below the water surface of the fish barrel pond according to the flow rate of the water body in the fish barrel pond.

[0018] Furthermore, the water outlet thrust of the water outlet causes the water body of the fish barrel breeding pond to form a rotating water flow. When the water outlet thrust of the water outlet satisfies the formation of a rotating water flow and a vortex in the water body of the fish barrel breeding pond, the water outlet can be set above the water surface of the water body of the fish barrel breeding pond, or part of the water outlet is set above the water surface of the water body of the fish barrel breeding pond, and part of the water outlet is set below the water surface of the water body of the fish barrel breeding pond.

[0019] Furthermore, the flow rate of the water flow in the fish barrel pool is set to 0.5 to 2.0 times the body length of the farmed fish per second.

[0020] Furthermore, the inner pipe is connected to the sewage pipe via an elbow three, and a ball valve two is provided between the elbow three and the inner pipe.

[0021] Furthermore, the length of the inner tube is greater than the length of the outer tube.

[0022] The length of the inner tube is 900 mm, the diameter of the inner tube is 50 mm, the length of the outer tube is 690 mm, and the diameter of the outer tube is 90 mm.

[0023] Furthermore, a tube bracket is provided on the outer surface of the upper end of the inner tube, which can fix the inner tube inside the outer tube (52) and prevent the inner tube from shaking left and right inside the outer tube.

[0024] Furthermore, it also includes a bottom bracket, which is arranged at the bottom of the fish tank pond.

[0025] Furthermore, the bottom bracket is composed of a bottom frame 1, a bottom frame 2, a bottom frame 3, a bottom frame 4 and a bottom frame 5, the bottom frame 1 is arranged below the circular plate, the bottom frame 2 and the bottom frame 3 are arranged at intervals on the outside of the bottom frame 1, and the bottom frame 4 and the bottom frame 5 are arranged between the bottom frame 2 and the bottom frame 3.

[0026] The working principle of the present invention is as follows: the aquaculture water flowing out of the circulation filtering device enters the main water inlet pipe, the bottom water inlet pipe is connected to three or more water push pipes through a three-way pipe or a multi-way pipe (according to the increase in the diameter of the fish barrel aquaculture pond, more water push pipes can be designed to be connected), the water push pipe is inclined through the inlet of the inclined water outlet pipe, and the water outlet thrust of the inclined water outlet pipe makes the water body of the fish barrel aquaculture pond form a rotating water flow and a vortex. Through the sewage siphon device set, in the process of discharging sewage, the principle of hydraulic cyclone concentration is utilized, that is, the centrifugal force of the cyclone generated by the water body of the fish barrel aquaculture pond itself and the solid particle waste in the water body of the fish barrel aquaculture pond are utilized. Solid-liquid separation is carried out according to the density difference between organic matter and water. The solid particulate waste organic matter component with higher density in the water mixture of the fish barrel breeding pond remains in the center of the bottom of the cylindrical fish barrel breeding pond, and sinks to the center of the bottom of the inverted cone barrel bottom of the fish barrel breeding pond under the action of vertical gravity, becoming a solid particulate waste organic matter concentrate. The water with lower density in the water mixture of the fish barrel breeding pond moves outward and downward along the central axis of the fish barrel breeding pond, forming a vortex under the constraint of the wall of the fish barrel breeding pond, and the particulate waste in the water sinks to the lower part of the inverted cone barrel bottom and slides to the center of the bottom of the inverted cone barrel bottom, achieving the purpose of solid-liquid separation.

[0027] The concentrated liquid rich in solid particulate pollutants such as fish feces and leftover feed accounts for about 5% of the water discharged from the fish barrel breeding pond. The concentrated liquid of solid particulate pollutants is discharged from the central opening at the bottom of the inverted cone bottom of the bottom frame after the flow rate is controlled by a siphon device. 95% of the discharged water from the fish barrel breeding pond is discharged through the discharge pipe set at the bottom of the circular barrel body and returned to the circulating water filtration device for treatment.

[0028] Compared with the prior art, the beneficial effects of this fish barrel breeding pond are: 1. The present invention, through the design of the working area, water push pipe and sewage siphon device of the cylindrical-inverted cone combination of the fish barrel culture pond, can quickly separate fish feces and residual feed from the culture water at a speed close to real time, greatly reducing the conversion of solid organic pollutants into water-soluble pollutants in the water, reducing the formation of ammonia nitrogen in the water, reducing the production of harmful pollutants such as ammonia and nitrite nitrogen that are sensitive to cultured organisms, reducing the pollutants in the culture water from the source, thereby achieving the purpose of purifying the culture water environment, providing a stable, reliable, comfortable and high-quality growth environment for cultured organisms, and providing favorable conditions for high-density culture.

[0029] 2. The design of the fish barrel culture pond device of the present invention combines the culture area for cultured organisms and the area for precipitation and solid-liquid separation and discharge of pollutants generated during the culture into one, which greatly saves construction space and construction costs.

[0030] 3. A sewage siphon device is arranged in the fish barrel breeding pond of the present invention, and the solid particle waste from the bottom of the fish barrel breeding pond is continuously discharged by adopting a sewage discharge method of a siphon structure. The solid particle waste in the discharged sewage has a high concentration degree, and the discharged sewage can be discharged at a small flow rate for a long time. The amount of discharged sewage is small, which saves sewage treatment energy consumption, sewage treatment chemicals, sewage treatment time, and sewage treatment device space, thereby achieving the purpose of environmental protection and energy saving.

[0031] 4. The fish barrel breeding pond of the present invention gathers, precipitates, concentrates and removes the solid particle pollutants as much as possible at the source of the solid particle pollutants, avoids the breakage caused by the water circulation disturbance, reduces the operating burden of the subsequent circulating water filtration device for water treatment, reduces the use of mechanical filtration equipment, thereby reducing the water resources used in the breeding water body, reduces the waste of water resources, and saves system energy consumption.

[0032] 5. The present invention is suitable for industrial high-density fish farming, and can self-clean and recycle the water in the fish barrel farming pond. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The water outlet thrust causes the water body of the fish barrel breeding pond to form a rotating water flow. When the water outlet thrust satisfies the formation of a rotating water flow and a vortex in the water body of the fish barrel breeding pond, the water outlet can be set above the water surface of the fish barrel breeding pond, or part of the water outlet can be set above the water surface of the fish barrel breeding pond, and part of the water outlet can be set below the water surface of the fish barrel breeding pond.

The siphon channel consists of an inner tube 51, an outer tube 52 and a top cover 54. The inner tube 51 is arranged in the middle of the outer tube 52. The top of the outer tube 52 is flush with the top of the fish tank pond 1. The air pressure regulating chamber 55 is arranged between the top of the inner tube 51 and the top of the outer tube 52.

[0046] The sewage siphon device adjusts the siphon flow rate by setting a siphon channel, and setting an air pressure regulating chamber 55 and an air pressure regulating valve 56 at the top of the siphon channel. When the sewage siphon device is working, the solid particle waste concentrated pollutant liquid flow at the bottom of the fish barrel breeding pool enters the siphon channel between the inner tube 51 and the outer tube 52 under the pressure of the high liquid level of the fish barrel breeding pool, and the liquid flows through the transition between the inner tube 51 and the outer tube 52, and the air pressure regulating chamber 55 flows to the inside of the inner tube 51 under the action of gravity, and then leads to the sewage pipe 3 for discharge.

The air pressure regulating chamber 55 is connected to the air pressure regulating valve 56, and the external air pressure is introduced through the air pressure regulating valve 56. The negative pressure in the air pressure regulating chamber 55 is adjusted by adjusting the opening of the air pressure regulating valve 56, thereby changing and adjusting the flow rate of the solid particle waste concentrated pollutant liquid flow.

[0047] The design of the sewage siphon device 5 does not require changing the cross-sectional area of ​​the siphon channel when adjusting the flow rate of the siphon liquid flow. It can continuously use a smaller water flow rate and concentrate the pollutant liquid flow at a speed close to real time to quickly separate fish feces and remaining feed from the aquaculture water body, thereby greatly reducing the conversion of solid organic pollutants into water-soluble pollutants in the aquaculture water body.

[0048] See also Figure 4-Figure 5 The bottom of the inverted conical barrel bottom 12 is a disc-shaped barrel bottom.

[0049] The bottom frame 53 includes a bottom disc 531 and a bottom disc support frame 532 . The diameter of the bottom disc 531 is smaller than or equal to the diameter of the disc-shaped barrel bottom.

[0050] See also Figure 6 , and also includes a bottom bracket 2, which is arranged at the bottom of the fish barrel pond 1.

[0052] The working principle of the present invention is as follows: the aquaculture water flowing out of the circulating filtration device enters the main water inlet pipe, the bottom water inlet pipe is connected to three or more water push pipes 4 through a three-way pipe or a multi-way pipe (according to the increase in the diameter of the fish barrel aquaculture pond, more water push pipes can be designed to be connected), the water push pipe 4 is inclined through the inlet of the oblique water outlet pipe 42, and the water outlet thrust of the oblique water outlet pipe 42 causes the water body of the fish barrel aquaculture pond to form a rotating water flow and a vortex. Through the sewage siphon device 5, in the process of discharging sewage, the principle of hydraulic cyclone concentration is utilized, that is, the centrifugal force of the cyclone generated by the water body of the fish barrel aquaculture pond itself and the solid in the water body of the fish barrel aquaculture pond are utilized. The solid-liquid separation is carried out according to the density difference between the solid particulate waste organic matter and the water body. The solid particulate waste organic matter component with higher density in the water mixture of the fish barrel breeding pond remains in the center of the bottom of the cylindrical fish barrel breeding pond, and sinks to the center of the bottom of the inverted cone barrel bottom of the fish barrel breeding pond under the action of vertical gravity, becoming a solid particulate waste organic matter concentrate. The water with lower density in the water mixture of the fish barrel breeding pond moves outward and downward along the central axis of the fish barrel breeding pond, forming a vortex under the constraint of the wall of the fish barrel breeding pond, and the particulate waste in the water body sinks to the lower part of the inverted cone barrel bottom and slides to the center of the bottom of the inverted cone barrel bottom, achieving the purpose of solid-liquid separation.

[0053] The concentrated liquid rich in solid particulate pollutants such as fish feces and leftover feed accounts for about 5% of the water discharged from the fish barrel breeding pond. The concentrated liquid of solid particulate pollutants is discharged from the central opening at the bottom of the inverted cone-shaped barrel bottom under the bottom frame after the flow rate is regulated by the sewage siphon device 5. 95% of the discharged water from the fish barrel breeding pond is discharged from the discharge pipe 6 set at the lower part of the circular barrel body and returned to the circulating water filtration device for treatment.
