Description

Technical Field

[0001] The present invention discloses a pressure aeration water pump and an operating method, which relate to a pressure aeration water pump and an operating method capable of increasing the turbulence of a water body to control the outbreak of blue algae in a natural water body, and belong to the technical field of aeration water pumping, and particularly to a pressure aeration water pump that supplies air to a pressure tank through an air pump, accurately controls the switch of a releaser through an automatic control device, and cyclically releases gas to disturb the water body and increase the turbulence, thereby effectively destroying the growth conditions of blue algae and controlling the outbreak of blue algae. Background Art

[0002] The rapid proliferation of cyanobacteria will cause serious damage to the ecological balance of water bodies, thus threatening water quality safety, affecting the surrounding ecological environment and human production and life. In order to control the outbreak of cyanobacteria, a variety of technical means have been developed. The commonly used impeller aerator controls the outbreak of cyanobacteria by increasing the turbulence of the water body. It can be applied to water bodies of different depths. However, its characteristic of being installed on the water surface causes it to affect shipping. When used in waters with relatively busy shipping, it will interfere with the normal water traffic order. At the same time, its operating power cost is high, and during long-term use, its inspection, maintenance and maintenance costs are also high; the water-lifting aerator developed by Xi'an University of Architecture and Technology is placed underwater to avoid interference with shipping, but the equipment is large in size and is only suitable for deep water areas such as reservoirs and lakes with a water depth of ≥8m. It cannot work in shallow waters, and its equipment cost is relatively high. Whether it is an impeller aerator or a water-lifting aerator, when faced with the treatment of blue-green algae in large areas of water, they will face huge economic and management cost pressures, and it is difficult to achieve the goal of efficient prevention and control and long-term stable treatment of blue-green algae outbreaks in large areas of water.

[0003] Publication No. CN1554601A discloses a multifunctional water-lifting aerator, a highly efficient water mixing and oxygenating device. The device is mainly composed of a central riser, an aeration chamber, an air chamber, and an air release pipe. The central riser is a section of circular tube, which can automatically adjust its length according to the water level. On the outside of its lower end, a concentric large-diameter tube wall is formed to form an aeration chamber and an air chamber. A perforated air release pipe is installed at the lower entrance of the aeration chamber. Compressed air enters the aeration chamber through the air release pipe for oxygenation, and the tail gas enters the air chamber. After the air chamber is full, the gas is concentrated and released to the central riser, forming large bubbles, which push the water flow of the central riser upward. The multifunctional water-lifting aerator is suspended by a float, vertically installed in the water, and anchored at the bottom by an anchor pier. The multifunctional water-lifting aerator can be used to mix the upper and lower water layers of reservoirs and lakes to inhibit the growth of algae; oxygenate the bottom water, improve the bottom aquatic ecological environment, and inhibit the dissolution and diffusion of phosphorus, ammonia nitrogen, iron, manganese and other substances in the bottom mud into the water. The above-mentioned water-lifting aerator is only applicable to deep water areas such as reservoirs and lakes with deep water depths, but cannot function in shallow water areas, and the equipment cost is relatively high. Summary of the invention

[0004] In order to improve the above situation, the present invention provides a pressure aeration water pump and an operating method, which provides a pressure aeration water pump that supplies air to a pressure tank through an air pump, accurately controls the switch of a releaser 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 the outbreak of cyanobacteria.

The releaser (10) is placed in the connecting tank (3), and the releaser (10) is fixedly placed on the top surface of the pressure tank (7). The air outlet pipe (6) is divided into two parts. One part of the air outlet pipe (6) passes through the side of the pressure tank (7) from the inside of the pressure tank (7), then passes through the side of the connecting tank (3) into the inside of the connecting tank (3) and is connected to the releaser (10). The other part of the air outlet pipe (6) has one end connected to the releaser (10), and the other end 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 end of the power line (4) is connected to the releaser (10), and the other end of the power line (4) passes through the side of the connection tank (3) and is placed outside the connection tank (3). The connection between the power line (4) and the side of the connection tank (3) is sealed. Preferably, the power cord (4) is sheathed with a waterproof sleeve or a heat shrink tube. Preferably, one of the automatic control devices (5) can be connected to a plurality of releasers (10) corresponding to a plurality of connection lines, and the plurality of releasers (10) are connected in parallel. A connecting buckle (11) is fixedly disposed in the middle of the bottom surface of the pressure tank (7). The connecting buckle (11) is in an arc-shaped structure. Both ends of the connecting buckle (11) are fixedly connected to the bottom surface of the pressure tank (7). One end of the soft rope (8) is wound around the connecting buckle (11), and the other end of the soft rope (8) is wound around the fixing member (9). The power assembly is composed of an air pump (1) and an automatic control device (5). The exhaust nozzle of the air pump (1) is sealedly connected to the air inlet pipe (2). Preferably, one air pump (1) can be connected to a plurality of air inlet pipes (2) at the same time through a joint. Preferably, one air pump (1) is capable of inflating multiple air inlet pipes (2) at the same time. The automatic control device (5) is connected to the other end of the power line (4), and the releaser (10) is electrically connected to the automatic control device (5) via the power box. Preferably, one of the automatic control devices (5) can be electrically connected to a plurality of releasers (10) via a plurality of power lines (4), and the plurality of releasers (10) are connected in parallel. The present invention also relates to an operating method of a pressure aeration water pump, which specifically comprises the following steps: (1) According to the actual area of ​​the water area, the number of required water pumping assemblies is accurately determined, and the number is greater than or equal to one, and multiple water pumping assemblies are combined in a parallel connection manner so that they are connected together and use the same air pump (1) and automatic control device (5); (2) For each pressure tank (7), use a soft rope (8) to tightly connect its bottom to the fixing member (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 member (9). If there are multiple water pump assemblies, it is necessary to ensure that the distances between the water pump assemblies are the same, so as to achieve uniform and comprehensive aeration treatment of the water area and avoid uneven local aeration or missed areas; (3) starting the air pump (1) to supply air to the pressure tank (7) through the air inlet pipe (2); when the pressure in the tank reaches a set value, the automatic control device (5) sends a signal, the releaser (10) opens the valve, and the gas in the pressure tank (7) is suddenly released into the water body in the form of an air bomb, and then rises rapidly and sprays out of the water surface. Under the action of air lifting, the water body is greatly disturbed, the turbulence of the water body is increased, and the stable water flow environment required for the growth of blue algae is effectively destroyed; (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 releaser (10) closes; (5) Thereafter, the air pump (1) continues to work, and the pressure in the pressure tank (7) gradually rises and reaches the set value again. The above operation steps are repeated in this way, thereby continuously and steadily increasing the turbulence of the water body, achieving effective control and suppression of the blue algae outbreak, and maintaining the balance and stability of the water body ecological environment; Example 2

[0014] The difference between this embodiment and the first embodiment is that the fixing member (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, the through hole is convenient for tying, and the tying is relatively strong, and the soft rope (8) will not be detached. Example 3

[0015] The difference between this embodiment and the first embodiment is that: a multi-porous nozzle (13) is fixedly arranged at one end of the outlet pipe (6) passing through the top surface of the connection tank (3); the multi-porous nozzle (13) is in a truncated cone-shaped structure and has an open structure at the bottom; the multi-porous nozzle (13) is in communication with the outlet pipe (6); the diameter of the multi-porous nozzle (13) gradually increases from one end connected to the outlet pipe (6) to the other end; a plurality of exhaust holes are provided at the top of the multi-porous nozzle (13); when in use, when the gas in the pressure tank (7) reaches the multi-porous nozzle (13) through the outlet pipe (6), it will be dispersed into a plurality of fine air flows and ejected from each exhaust hole, so that the contact area between the gas and the water body is instantly greatly increased, and a large number of tiny bubbles are generated. These bubbles continue to 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 distributed in layers in the water body. It has a better inhibitory effect; Example 4

[0016] The difference between this embodiment and embodiment 1 is that a spiral guide plate (14) is disposed inside the outlet pipe (6) passing through the top surface of the connecting tank (3) from the inside of the connecting tank (3). The edge of the spiral guide plate (14) is fixedly connected to the inner side surface of the outlet pipe (6) and is placed close to the top of the outlet pipe (6). The spiral guide plate (14) has a spiral structure. When in use, the gas can form a spiral rising airflow under the guidance of the spiral guide plate (14). When the spiral airflow rises in the water body, it will drive the surrounding water body to produce a rotational motion. Combined with the original vertical rising air lift effect, a complex three-dimensional water flow motion is formed, which greatly enhances the mixing effect and turbulence of the water body, making it difficult for algae to grow and reproduce in a relatively stable environment. In addition, this complex water flow motion can better mix the bottom nutrient-rich water body with the surface water body, change the distribution of nutrients available to the algae, and further inhibit its abnormal growth. The volume of the pressure tank (7) can be designed to be less than 5L. The smaller volume makes it more flexible and applicable to a variety of water environments. It can be well placed in relatively narrow waters or areas with certain restrictions on the volume of the equipment, and is easy to transport and operate. The bottom surface of the connecting tank (3) is fixedly placed on the top surface of the pressure tank (7), and its cylindrical structure and bottom opening design provide a relatively independent and stable installation space for components such as the releaser (10); One end of the air inlet pipe (2) passes 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 is sealed and connected to the side of the pressure tank (7), thereby ensuring that gas will not leak when the air pump (1) supplies gas, thereby ensuring that the pressure in the pressure tank (7) is stably established; The design that one air pump (1) can inflate multiple air inlet pipes (2) at the same time improves the air supply efficiency and application range of the equipment, and can drive multiple water pumping components to work through one power source, which is particularly suitable for large-area water management, and reduces equipment cost and operating energy consumption; The one automatic control device (5) can be electrically connected to a plurality of releasers (10) via a plurality of power lines (4). The design of connecting the plurality of releasers (10) in parallel enables unified management and precise control of all releasers (10) when a plurality of water pumping assemblies are used in a large area of ​​water, thereby improving the operability and management efficiency of the equipment when it is used in a large area of ​​water; The gas outlet pipe (6) is divided into two parts. One part of the gas outlet pipe (6) passes through the side of the pressure tank (7) from the inside of the pressure tank (7), then passes through the side of the connecting tank (3) into the inside of the connecting tank (3) and is connected to the releaser (10). Another part of the gas outlet pipe (6) is connected to the releaser (10) at one end, and the other end 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 body. This layout ensures smooth transmission of gas between the pressure tank (7), the connecting tank (3) and the water body, so that the gas can be sprayed into the water body at a suitable position and time, causing great disturbance to the water body under the action of gas lift, increasing the turbulence of the water body, and effectively inhibiting the growth of blue algae. The power cord (4) is designed with a waterproof sleeve or a heat shrink tube on the outside, which effectively prevents the power cord (4) from short circuiting or leaking electricity due to water erosion when working underwater, thereby 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 automatic control device (5) controlling the releaser (10); A connecting buckle (11) is fixedly disposed in the middle of the bottom surface of the pressure tank (7). The connecting buckle (11) is in 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 wound 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 due to factors such as water flow underwater, ensure the reliable connection between the water pumping device assembly and the fixing member (9), and enable the water pumping device to maintain a stable position relationship in the water, which is conducive to the normal operation and long-term use of the equipment; One end of the soft rope (8) is wound around the connecting buckle (11), and the other end of the soft rope (8) is wound around the fixing member (9). The material has certain flexibility and strength, and can adapt to complex underwater environmental conditions. While ensuring the reliability of the connection, it will not cause additional stress damage to the water pump assembly or the fixing member (9) due to excessive rigidity. It can also buffer the impact force of the water flow on the water pump assembly to a certain extent, and maintain the relatively stable position of the water pump in the water. The use of the soft rope (8) makes the connection between the water pump assembly and the fixing member (9) more convenient and flexible, and the distance between the two can be easily adjusted according to the actual water depth and equipment layout requirements, which is convenient for the installation and commissioning of the equipment. When the equipment needs to be maintained or moved, the soft rope (8) can also be easily untied or reconnected, thereby improving the convenience of equipment operation. The purpose is to supply gas to the pressure tank (7) through the air pump (1), accurately control the switch of the releaser (10) through the automatic control device (5), and release gas in a cyclic operation to disturb the water body and increase turbulence, thereby effectively destroying the growth conditions of blue algae and controlling the outbreak of blue algae.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] It should be further pointed out that, when describing the above specific embodiment, for the sake of simplicity and clarity, only the differences between the above specific embodiment and other embodiments are described, but those skilled in the art should know that the above specific embodiment itself is also an independent technical solution.
