Description

Technical Field

[0001] This invention relates to a pressure aerator and its operating method, which can increase the turbulence of water bodies to control cyanobacterial blooms in natural water bodies. It belongs to the field of aeration and water pumping technology, and specifically relates to a pressure aerator that supplies air to a pressure tank through an air pump, precisely controls the opening and closing of the release device through an automatic control device, and cyclically releases gas to disturb the water body and increase turbulence, thereby effectively destroying the growth conditions of cyanobacteria and controlling cyanobacterial blooms. Background Technology

[0002] The rapid proliferation of cyanobacteria can severely disrupt the ecological balance of aquatic bodies, threatening water quality and impacting the surrounding environment as well as human production and daily life. Various technologies have been developed to control cyanobacterial blooms. Commonly used impeller-type aerators control blooms by increasing water turbulence and are suitable for waters of varying depths. However, their surface-mounted nature can disrupt navigation, interfering with normal water traffic in busy areas. Furthermore, their operating costs are high, and long-term maintenance and repair expenses are also significant. The water-lifting aerator developed by Xi'an University of Architecture and Technology is placed underwater, avoiding interference with navigation. However, this equipment is bulky and only suitable for deep water areas such as reservoirs and lakes with a depth of ≥8m. It is ineffective in shallower waters, and its cost is relatively high. Whether it's a paddlewheel aerator or a pumping aerator, both face enormous economic and management costs when dealing with large-scale cyanobacteria outbreaks, making it difficult to achieve the goals of efficient prevention and long-term stable management.

[0003] Publication No. CN1554601A discloses a multifunctional water-lifting aerator, a highly efficient water mixing and oxygenation device. The device mainly consists of a central riser, an aeration chamber, an air chamber, and an air release pipe. The central riser is a section of circular pipe that automatically adjusts its length according to the water level. Concentric large-diameter pipe walls surround the aeration chamber and air chamber on its lower outer side. A perforated air release pipe is installed at the inlet below the aeration chamber. Compressed air enters the aeration chamber through the air release pipe to oxygenate, while exhaust gas enters the air chamber. Once the air chamber is full, the gas is released into the central riser, forming large bubbles that propel the water flow upwards. The multifunctional water-lifting aerator is suspended by a float, vertically installed in the water, and anchored at the bottom by anchoring blocks. This multifunctional water-lifting aerator can be used to mix the upper and lower water layers of reservoirs and lakes, inhibiting algae growth; oxygenating the bottom water, improving the bottom aquatic ecological environment, and inhibiting the dissolution and diffusion of substances such as phosphorus, ammonia nitrogen, iron, and manganese from the bottom sediment into the water. The aforementioned water-lifting aerator is only suitable for deep water areas such as reservoirs and lakes. It cannot be effective in shallow water areas, and its equipment cost is relatively high. Summary of the Invention

[0004] To improve the above situation, the present invention provides a pressure aerator and operating method that provides a pressure aerator that supplies air to a pressure tank by an air pump, precisely controls the switch of the release device by an automatic control device, and releases gas in a cyclical operation to disturb the water body and increase turbulence, thereby effectively destroying the growth conditions of cyanobacteria and controlling cyanobacteria blooms.

[0005] The pressure aerator and its operating method of the present invention are implemented as follows: The pressure aerator and its operating method of the present invention include a pump assembly and a power assembly.

[0008] The pressure tank has a hollow cylindrical structure.

[0009] Preferably, the volume of the pressure tank is less than 5L.

[0010] The bottom surface of the connecting tank is fixedly placed on the top surface of the pressure tank. The connecting tank has a cylindrical structure and an open bottom.

[0011] One end of the air inlet pipe passes through the side of the pressure tank from inside the pressure tank to the outside of the pressure tank, and is sealed to the side of the pressure tank.

[0012] The release device is placed inside the connecting tank, and the release device is fixedly placed on the top surface of the pressure tank.

[0013] The vent pipe is divided into two parts. One part of the vent pipe extends from the inside of the pressure tank to the side of the pressure tank, then passes through the side of the connecting tank and enters the interior of the connecting tank to connect with the release device. The other part of the vent pipe is connected to the release device at one end, and extends from the inside of the connecting tank through the top surface of the connecting tank to the outside of the connecting tank.

[0014] One end of the power cord is connected to the release device, and the other end of the power cord passes through the side of the connecting can and is placed outside the connecting can. The connection between the power cord and the side of the connecting can is sealed.

[0015] Preferably, the power cord is fitted with a waterproof sleeve or heat shrink tubing.

[0016] Preferably, one of the aforementioned automatic control devices can be connected to multiple release devices via multiple connection lines, and the multiple release devices are connected in parallel.

[0017] A connecting buckle is fixedly placed in the middle of the bottom surface of the pressure tank. The connecting buckle has an arc-shaped structure, and its two ends are fixedly connected to the bottom surface of the pressure tank.

[0018] One end of the soft rope is wrapped around the connecting buckle, and the other end of the soft rope is wrapped around the fixing component.

[0019] Preferably, the fixing element is a falling stone.

[0020] The power unit consists of an air pump and an automatic control device.

[0021] The air pump exhaust nozzle is sealed to the air intake pipe.

[0022] Preferably, one of the air pumps can be connected to multiple air inlet pipes simultaneously via a connector.

[0023] Preferably, one of the air pumps can simultaneously inflate multiple air inlet pipes.

[0024] The automatic control device is connected to the other end of the power cord, and the release device is electrically connected to the automatic control device through the power supply box.

[0025] Preferably, one of the self-control devices can be electrically connected to multiple releases via multiple power lines, and the multiple releases are connected in parallel.

[0026] Furthermore, the fixing component is a small cast iron weight, and the other end of the soft rope passes through the through hole of the small cast iron weight and is tied to the soft rope.

[0027] Furthermore, a multi-hole nozzle is fixedly mounted on one end of the vent pipe that extends out of the top surface of the connecting tank. The multi-hole nozzle has a frustum-shaped structure with an open bottom. The multi-hole nozzle is connected to the vent pipe, and its diameter gradually increases from the end connected to the vent pipe to the other end. The top of the multi-hole nozzle has multiple exhaust holes.

[0028] Furthermore, a spiral guide plate is placed inside the vent pipe that extends from the inside of the connecting tank to the top surface of the connecting tank. The edge of the spiral guide plate is fixedly connected to the inner side of the vent pipe and is placed near the top of the vent pipe. The spiral guide plate has a spiral structure.

[0029] This invention also relates to an operating method for a pressure aerator, comprising the following steps:

[0030] (1) Based on the actual size of the water area, accurately determine the number of pumping device components required, and the number is greater than or equal to one. Combine multiple pumping device components in parallel so that they can be connected together and use the same air pump and automatic control device.

[0031] (2) For each pressure tank, use a soft rope to tightly connect its bottom to the fixed part, and then slowly sink it into the water so that the water pump assembly can be stably suspended in the water above the fixed part. If there are multiple water pump assemblies, it is necessary to ensure that the distance between each water pump assembly is the same in order to achieve uniform and comprehensive aeration treatment of the water area and avoid uneven aeration or missed areas.

[0032] (3) Start the air pump and supply air into the pressure tank through the air inlet pipe. When the pressure in the tank reaches the set value, the automatic control device sends a signal and the release device opens the valve. The gas in the pressure tank is suddenly released into the water in the form of an air bomb, and then rises rapidly and sprays out of the water surface. Under the action of air lifting, it will cause great disturbance to the water body, increase the turbulence of the water body, and effectively destroy the stable water flow environment required for the growth of cyanobacteria.

[0033] (4) As the gas is released, the pressure inside the pressure tank gradually decreases. When the pressure drops to a specific set value, the automatic control device sends a signal and the valve of the release device closes.

[0034] (5) After that, the air pump continues to work, and the pressure in the pressure tank will gradually rise and reach the set value again. The above operation steps are repeated in this way, thereby continuously and stably increasing the turbulence of the water body, realizing the effective control and suppression of cyanobacterial blooms, and maintaining the balance and stability of the aquatic ecological environment. Beneficial effects

[0035] First, it can flexibly determine the number of pumping unit components based on the water area and use them in parallel, making it suitable for water areas of different sizes, whether large or small.

[0036] Second, it is suitable for water bodies of various depths, especially shallow water bodies, and can be applied to more types of aquatic environments.

[0037] Third, multiple pumping units can share a single air pump and automatic control device, resulting in a lower overall equipment purchase cost. Furthermore, due to the use of intermittent aeration, the rated flow rate of the air pump is small, leading to lower operating power costs.

[0038] Fourth, the pump itself has no moving parts, resulting in a low failure rate and reducing the risk of use due to wear and tear or malfunction of parts. At the same time, the air pump and automatic control device are located on the shore, making their installation, maintenance and operation simple. Attached Figure Description

Detailed Implementation Example 1

[0047] The present invention discloses a pressure aerator and its operating method, which are implemented as follows: The present invention discloses a pressure aerator and its operating method, comprising a pump assembly and a power assembly.

The other part of the vent pipe (6) is connected to the release device (10) at one end, and the other end extends from the inside of the connecting tank (3) through the top surface of the connecting tank (3) and is placed outside the connecting tank (3).

[0056] One end of the power cord (4) is connected to the release device (10), and the other end of the power cord (4) passes through the side of the connecting can (3) and is placed outside the connecting can (3). The connection between the power cord (4) and the side of the connecting can (3) is sealed.

[0057] Preferably, the power cord (4) is covered with a waterproof sleeve or heat shrink tubing.

[0058] Preferably, one of the self-control devices (5) can be connected to multiple releases (10) via multiple connecting lines, and the multiple releases (10) are connected in parallel.

[0060] One end of the soft rope (8) is wrapped around the connecting buckle (11), and the other end of the soft rope (8) is wrapped around the fixing member (9).

[0061] The power unit consists of an air pump (1) and an automatic control device (5).

[0062] The exhaust port of the air pump (1) is sealed to the intake pipe (2).

[0063] Preferably, one of the air pumps (1) can be connected to multiple air inlet pipes (2) simultaneously via a connector.

[0064] Preferably, one of the air pumps (1) is capable of simultaneously filling multiple air inlet pipes (2).

[0065] The automatic control device (5) is connected to the other end of the power cord (4), and the release device (10) is electrically connected to the automatic control device (5) through the power supply box.

[0066] Preferably, one of the self-control devices (5) can be electrically connected to multiple releases (10) via multiple power lines (4), and the multiple releases (10) are connected in parallel.

[0067] This invention also relates to an operating method for a pressure aerator, specifically including the following steps:

[0068] (1) Based on the actual area of ​​the water body, accurately determine the number of pumping components required, and the number is greater than or equal to one. Combine multiple pumping components in parallel so that they can be connected and use the same air pump (1) and automatic control device (5).

[0069] (2) For each pressure tank (7), use a soft rope (8) to tightly connect its bottom to the fixing part (9), and then slowly sink it into the water so that the water pump assembly can be stably suspended in the water above the fixing part (9). If there are multiple water pump assemblies, it is necessary to ensure that the distance between each water pump assembly is the same in order to achieve uniform and comprehensive aeration treatment of the water area and avoid uneven aeration or missed areas.

[0070] (3) Start the air pump (1) and supply air to the pressure tank (7) through the air inlet pipe (2). When the pressure inside the tank reaches the set value, the automatic control device (5) sends a signal and the release device (10) opens the valve. The gas in the pressure tank (7) is suddenly released into the water in the form of an air bomb, and then rises rapidly and sprays out of the water surface. Under the action of air lifting, it will cause great disturbance to the water body, increase the turbulence of the water body, and effectively destroy the stable water flow environment required for the growth of cyanobacteria.

[0071] (4) As the gas is released, the pressure in the pressure tank (7) gradually decreases. When the pressure drops to a specific set value, the automatic control device (5) sends a signal and the valve of the release device (10) closes.

[0072] (5) After that, the air pump (1) continues to work, and the pressure in the pressure tank (7) will gradually rise and reach the set value again. The above operation steps are repeated in this way, thereby continuously and stably increasing the turbulence of the water body, realizing the effective control and suppression of cyanobacterial blooms, and maintaining the balance and stability of the aquatic ecological environment. Example 2

[0073] The difference between this embodiment and embodiment 1 is that the fixing component (9) is a small cast iron weight (12), and the other end of the soft rope (8) passes through the through hole of the small cast iron weight (12) and is tied to the soft rope (8). When in use, its own through hole makes it easy to tie, and the tie is relatively strong, so the soft rope (8) will not come off. Example 3

[0074] The difference between this embodiment and embodiment 1 is that: a multi-hole nozzle (13) is fixedly placed at one end of the air outlet pipe (6) that passes through the top surface of the connecting tank (3). The multi-hole nozzle (13) has a frustum-shaped structure and an open structure at the bottom. The multi-hole nozzle (13) is connected to the air outlet pipe (6). The diameter of the multi-hole nozzle (13) gradually increases from one end connected to the air outlet pipe (6) to the other end. The top of the multi-hole nozzle (13) has multiple exhaust holes. When in use, when the gas in the pressure tank (7) reaches the multi-hole nozzle (13) through the air outlet pipe (6), it will be dispersed into multiple fine airflows and sprayed out from each exhaust hole, which will instantly increase the contact area between the gas and the water body and generate a large number of tiny bubbles. These bubbles will continuously disturb the water body during the rising process, forming a more dense and uniform turbulent effect, which can more accurately destroy the growth environment of algae in different water layers, especially for some algae that are distributed in layers in the water body, which has a better inhibitory effect. Example 4

[0075] The difference between this embodiment and embodiment 1 is that: a spiral guide plate (14) is placed inside the air outlet pipe (6) that passes through the inside of the connecting tank (3) and extends out of the top surface of the connecting tank (3). The edge of the spiral guide plate (14) is fixedly connected to the inner side of the air outlet pipe (6) and placed near the top of the air outlet pipe (6). The spiral guide plate (14) has a spiral structure. When in use, the gas can form a spiral upward airflow under the guidance of the spiral guide plate (14). When this spiral airflow rises in the water, it will drive the surrounding water to rotate. Combined with the original vertical upward air lift effect, it forms a complex three-dimensional water flow movement, which greatly enhances the mixing effect and turbulence of the water, making it difficult for algae to grow and reproduce in a relatively stable environment. In addition, this complex water flow movement can better mix the bottom water rich in nutrients with the surface water, change the distribution of nutrients available to algae, and further inhibit their abnormal growth.

[0076] The pressure tank (7) is designed to have a volume of less than 5L. Its smaller volume makes it more flexible and suitable for various aquatic environments. It can be well installed in relatively narrow waters or areas where the size of the equipment is limited, and it is easy to transport and operate.

[0077] The bottom surface of the connecting tank (3) is fixedly placed on the top surface of the pressure tank (7). Its cylindrical structure and bottom opening design provide a relatively independent and stable installation space for components such as the release device (10).

[0078] The design of the air inlet pipe (2) passing through the side of the pressure tank (7) from the inside of the pressure tank (7) to the outside of the pressure tank (7) and being sealed to the side of the pressure tank (7) ensures that the gas will not leak when the air pump (1) supplies gas, and ensures the stable establishment of the pressure inside the pressure tank (7).

[0079] The design of one air pump (1) that can simultaneously fill multiple air inlet pipes (2) improves the air supply efficiency and applicability of the equipment. It can drive multiple water pump components through one power source, which is especially suitable for large-area water treatment and reduces equipment cost and operating energy consumption.

[0080] The automatic control device (5) can be electrically connected to multiple release devices (10) through multiple power lines (4). The parallel design of multiple release devices (10) enables unified management and precise control of all release devices (10) when using multiple water pump components in a large area of ​​water, thereby improving the operability and management efficiency of the equipment when applied in a large area of ​​water.

[0081] The gas outlet pipe (6) is divided into two parts. One part of the gas outlet pipe (6) passes through the inside of the pressure tank (7) and out of the side of the pressure tank (7), and then passes through the side of the connecting tank (3) and into the inside of the connecting tank (3) to connect with the releaser (10). The other part of the gas outlet pipe (6) is connected to the releaser (10) at one end and passes through the top surface of the connecting tank (3) from the inside of the connecting tank (3) and is placed outside the connecting tank (3). One part is responsible for transmitting the gas in the pressure tank (7) to the releaser (10), and the other part guides the gas released by the releaser (10) to the outside of the connecting tank (3) and finally sprays it into the water. This layout ensures the smooth transmission of gas between the pressure tank (7), the connecting tank (3) and the water, so that the gas can be sprayed into the water at the right position and time. Under the action of air lifting, it causes great disturbance to the water, increases the turbulence of the water, and effectively inhibits the growth of blue-green algae.

[0082] The design of the power cord (4) being covered with a waterproof sleeve or heat shrink tubing effectively prevents electrical faults such as short circuits or leakage caused by water erosion when the power cord (4) is working underwater, ensuring the safe operation of the equipment, extending the service life of the power cord (4), and also ensuring the reliability and stability of the control device (5) controlling the release device (10).

[0083] A connecting buckle (11) is fixedly placed in the middle of the bottom surface of the pressure tank (7). The connecting buckle (11) has an arc-shaped structure. The design of the two ends of the connecting buckle (11) being fixedly connected to the bottom surface of the pressure tank (7) provides a stable connection point for the soft rope (8). One end of the soft rope (8) is wrapped around the connecting buckle (11), which can ensure the firmness of the connection between the soft rope (8) and the pressure tank (7), prevent the soft rope (8) from falling off underwater due to factors such as water flow, ensure the reliable connection between the pump assembly and the fixing part (9), and enable the pump to maintain a stable position in the water, which is conducive to the normal operation and long-term use of the equipment.

[0084] The design of the soft rope (8) with one end wrapped around the connecting buckle (11) and the other end wrapped around the fixing part (9) has a certain degree of flexibility and strength, which can adapt to the complex underwater environment. While ensuring the reliability of the connection, it will not cause additional stress damage to the pump assembly or the fixing part (9) due to excessive rigidity. It can also buffer the impact of the water flow on the pump assembly to a certain extent, maintain the relatively stable position of the pump in the water. The use of the soft rope (8) makes the connection between the pump assembly and the fixing part (9) more convenient and flexible. It can easily adjust the distance between the two according to the actual water depth and equipment layout requirements, which is convenient for the installation and debugging of the equipment. When the equipment needs to be maintained or moved, the soft rope (8) can be easily untied or reconnected, which improves the convenience of equipment operation.

[0085] The goal is to supply gas to the pressure tank (7) through the air pump (1), and to precisely control the switch of the release device (10) through the automatic control device (5), so as to release gas in a cyclical operation to disturb the water body and increase turbulence, thereby effectively destroying the growth conditions of cyanobacteria and controlling the cyanobacteria outbreak.

[0086] It should be noted that, unless otherwise explicitly specified and limited, the terms "placed," "connected," and "linked" should be interpreted broadly. For example, they can refer to fixed connections such as folded edges, rivets, pins, adhesives, and welds; detachable connections such as threaded connections, snap-fit ​​connections, and hinges; integral connections; electrical connections; direct connections; or indirect connections via an intermediate medium; or internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0087] It should be further noted that, in order to keep the description simple and clear, the above specific embodiments only describe the differences between them and other embodiments. However, those skilled in the art should know that the above specific embodiments are also independent technical solutions.
