Description

Technical Field

[0001] The invention relates to the technical field of micro-nano aerators, and in particular to a micro-nano aeration oxygen enrichment device and a working method thereof. Background Art

[0002] A micro-nano aeration oxygen enrichment device (also called an aerator) is a device that uses a high-speed rotating pump impeller to mix and stir liquid and gas so that the gas and liquid can be fully dissolved. It is usually used to introduce air into water to effectively increase the oxygen content in the water, thereby promoting the growth of microorganisms and the degradation of organic pollutants. It can be widely used in sewage treatment, aquaculture, water eutrophication prevention and other scenarios.

[0003] During the use of the micro-nano aeration and oxygen enrichment device, a water pump is required to pump water from the external environment. Since the outdoor pools and reservoirs are in a harsh environment, the water contains impurities such as aquatic plants and waste, so a filter device is required to filter the water when pumping. After a period of use, the filter device will be blocked by impurities, making the micro-nano reoxygenation device unusable. In the existing structure, the filter device can usually only be cleaned manually after shutdown, which is inconvenient to use and cannot be discovered in time when it is blocked.

[0020] Furthermore, a guide rod extending in a vertical direction is fixedly arranged in the self-floating filter box, a through hole penetrating from top to bottom is arranged on the floating plate, and the guide rod passes through the through hole.

[0021] Furthermore, a limit block is arranged on the guide rod, the top of the limit block is higher than the filtering structure, and the width of the limit block is larger than the diameter of the through hole, so as to limit the movement of the floating plate above the limit block.

[0022] Furthermore, the water suction pipe includes a first right-angle elbow and a first rubber tube; one end of the first right-angle elbow extends into the self-floating filter box, the other end of the first right-angle elbow is connected to one end of the first rubber tube, and the other end of the first rubber tube is connected to the functional component.

[0023] Furthermore, the recoil pipe includes a second right-angle bend pipe and a second rubber tube; one end of the second right-angle bend pipe extends into the self-floating filter box, the other end of the second right-angle bend pipe is connected to one end of the second rubber tube, and the other end of the second rubber tube is connected to the functional component.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present invention relates to a micro-nano aeration oxygen enrichment device, such as Figures 1 to 5 As shown, including:

[0044] The floating platform 1 floats on the water surface and serves as the base of the entire device. The floating platform 1 should be made of lightweight and corrosion-resistant materials to ensure durability for long-term use. Handles can be provided on the top of the side of the floating platform 1 as needed to facilitate transportation.

[0045] Functional components include a gas compressor for compressing external air and a diaphragm pump for pumping water; the functional components usually also include wires, valve bodies and other components required for the gas compressor and the diaphragm pump. The installation and use of these components are prior art and will not be described in detail here;

[0046] The protective cover 2 is arranged on the floating platform 1 and is used to cover the functional components to protect the components of the functional components from being affected by the outside world during operation;

[0047] The aeration plate 3 is arranged on the side of the floating platform 1 and connected to the functional components through the aeration pipe 4; the water mixed with the air is transported to the aeration plate 3 through the aeration pipe 4, and finally sent to the pool through the aeration plate 3; the aeration plate 3 can further disperse the water sprinkled into the pool, so that the water is quickly mixed with the water in the pool; part of the aeration pipe 4 can be arranged inside the floating platform 1 to reduce the impact of the outside on the aeration pipe 4;

[0048] The self-floating filter box 5 is arranged on the side of the floating platform 1; the bottom and the bottom of the side of the self-floating filter box 5 are provided with a filter structure 5a; the filter structure 5a can be a filter hole structure directly opened on the self-floating filter box 5, or an additional filter element, or a combination of the above two. The specific structure can be selected according to the needs of the use scenario;

[0049] A water suction pipe 6, one end of which extends into the self-floating filter box 5, and the other end is connected to the diaphragm pump in the functional component, and the diaphragm pump draws water from the self-floating filter box 5 through the water suction pipe 6;

[0050] The backwash pipe 7 has one end extending into the self-floating filter box 5 and the other end connected to the gas compressor or diaphragm pump in the functional component, and is used to transport gas or water to the self-floating filter box 5 during backwash cleaning.

[0051] The specific principle of this oxygen enrichment device is as follows:

[0052] Conventional filters are usually directly connected to or installed inside an oxygen-enriched device. In this case, it is not only inconvenient to disassemble and clean the filter, but also when the filter is clogged, if backwashing is performed directly, the space around the filter is very small due to the installation method of the filter. Therefore, impurities are easy to stay around the filter and quickly block the filter again.

[0053] The oxygen enrichment device adopts the method of floating the self-floating filter box 5 alone beside the floating platform 1. The self-floating filter box 5 will be driven by the backwash pipe 7 to move with the floating platform 1, but the backwash pipe 7 will not limit the shaking of the self-floating filter box 5 (this shaking is caused by the ripples of the water surface, etc.). In the oxygen enrichment device, the filter structure 5a is set at the bottom and the bottom of the side of the self-floating filter box 5, so that it can shake with the self-floating filter box 5 in the direction where impurities are not easy to accumulate, and it is difficult for impurities to stay on the filter structure 5a, which effectively reduces the risk of clogging of the filter structure 5a.

[0054] In addition, the traditional installation method makes it difficult to directly detect when the filter is clogged. The detection method usually indirectly reflects the blockage of the filter through the flow rate of water pumped by the water pump. However, once blockage occurs and the flow rate decreases, the power of the water pump remains unchanged, which will cause the pump to heat up easily; and large impurities (such as branches, leaves, aquatic plants, etc.) often block the filter in an instant, causing the pump to fail to pump water and run idle, seriously affecting the life of the pump.

[0055] The self-floating filter box 5 adopts an independent floating structure. After the filter structure 5a is blocked, as the diaphragm pump pumps water, the outside water cannot enter the self-floating filter box 5 due to the blockage, or the speed of entering is not fast enough to fill the amount of water pumped away, which will cause the water in the self-floating filter box 5 to become less and less, so that the self-floating filter box 5 begins to float. Figure 5 As shown, by detecting the floating condition of the self-floating filter box 5, the clogging of the filter structure 5a can be quickly discovered and stopped at the early stage of the pumping operation of the diaphragm pump, thereby effectively protecting the diaphragm pump.

[0056] After finding that the filter structure 5a is clogged, the backwash function can be started. At this time, gas or water will be sent out from the functional component and enter the self-floating filter box 5 along the backwash pipe 7. Then the gas or water will pass through the filter structure 5a from the inside to the outside, and the impurities blocked on the filter structure 5a will be washed away. It is best to use gas for backwashing, so that the self-floating filter box 5 can produce a certain amount of shaking during the backwashing process, so that the filter structure 5a can get rid of impurities faster.

[0057] During the use of the oxygen enrichment device, in order to prevent the floating platform 1 from moving on the water surface, an anchor or other structure can be used to fix the floating platform 1, and the present structure proposes a more optimal structural form: the floating platform 1 is a triangular structure, and three aeration discs 3 are set, respectively at the three corners of the floating platform 1. During the use of the oxygen enrichment device, the aeration discs 3 can generate a certain thrust to the oxygen enrichment device when discharging outwards, and the balance of the three thrusts can make the floating platform 1 stay in place; and when the wind is strong, the thrust of the wind on the oxygen enrichment device can be offset to a certain extent by reducing or closing the discharge volume of the aeration discs 3 at the upwind position, or increasing the discharge volume of the aeration discs 3 at the downwind position, so that the oxygen enrichment device can stay in place as much as possible.

[0058] Preferably, the aeration pipe 4 is provided with a first vertical section 4a connected to the aeration plate 3 and a second vertical section 4b connected to the functional component, and the top of the first vertical section 4a is connected to the top of the second vertical section 4b, such as Figure 2 As shown, the aeration pipe 4 forms a "J" shape in this part. During the flow of water mixed with air, the gas tends to float up and accumulate above the water pipe, and the above structure enables the water to hit the corners multiple times when passing through the "J" shaped structure, so that the water and air are further mixed, thereby further increasing the amount of oxygen dissolved in the water.

[0059] When detecting the blocking condition of the filter structure 5a, considering the shaking of the water surface, the self-floating filter box 5 does not have a good external reference to quickly reflect its floating condition. It can only be observed from the outside after it floats to a certain degree. At this time, the amount of water that the diaphragm pump can pump away will become relatively small, which poses a certain risk. At the same time, as the amount of water in the self-floating filter box 5 decreases, there is also a risk that the water suction pipe 6 cannot contact the water. In order to solve the above problems, the oxygen enrichment device also includes:

[0060] The floating plate 8 is a plastic structure and is placed in the self-floating filter box 5; the water suction pipe 6 passes through the opening above the self-floating filter box 5 and is then fixedly connected to the floating plate 8, and the end of the water suction pipe 6 is lower than the floating plate 8;

[0061] The liquid level detector 9 is fixedly mounted on the self-floating filter box 5 and is used to detect the liquid level position in the self-floating filter box 5;

[0062] The backwash pipe 7 is fixedly connected to the self-floating filter box 5 , and the end of the backwash pipe 7 is arranged at the bottom of the self-floating filter box 5 . The backwash pipe 7 passes through the floating plate 8 and does not contact the floating plate 8 .

[0063] The principle of the above structure is as follows: the floating plate 8 will move with the liquid level in the self-floating filter box 5, thereby driving the water suction pipe 6 to move, to ensure that the mouth of the water suction pipe 6 can always be extended into the water, thereby avoiding the diaphragm pump from running idle. The liquid level detector 9 directly detects the depth of the liquid level in the self-floating filter box 5. The liquid level detector 9 itself will move with the up and down floating of the self-floating filter box 5, and the liquid level will always be aligned with the water surface of the pool, and the water in the self-floating filter box 5 will not be affected by the outer waves and is relatively stable. In this way, during the use of the oxygen enrichment device, the liquid level drop detected by the liquid level detector 9 is the floating amount of the self-floating filter box 5. When it is detected that the liquid level drop reaches a certain value, it means that the filter structure 5a is blocked, causing the liquid level detector 9 to float to a certain extent. At this time, it can be determined that the filter structure 5a is blocked and backwashing operation is performed.

[0064] Preferably, a detachable mounting flange 5b is provided on the self-floating filter box 5, and the liquid level detector 9 is mounted on the mounting flange 5b. During assembly, since there is no water in the self-floating filter box 5, the mounting flange 5b and the liquid level detector 9 can be left unmounted first, and the liquid level detector 9 can be installed after the self-floating filter box 5 is placed in water, so that the liquid level detector 9 can be debugged more conveniently. When the self-floating filter box 5 needs to be cleaned, the mounting flange 5b and the liquid level detector 9 can be removed first, and then taken out of the water.

[0065] In order to prevent the floating plate 8 from shaking in the self-floating filter box 5, it is preferred to fix a guide rod 5c extending in the vertical direction in the self-floating filter box 5, and set a through hole extending vertically on the floating plate 8, through which the guide rod 5c passes, and the guide rod 5c is used to limit the horizontal movement of the floating plate 8. Two or more guide rods 5c can be set in the self-floating filter box 5, so as to further limit the rotation of the floating plate 8 in the horizontal direction.

[0066] In order to prevent the water suction pipe 6 from sticking to the bottom of the self-floating filter box 5 and making it impossible to pump water, the oxygen enrichment device preferably provides a limit block 5d on the guide rod 5c, the top of the limit block 5d is higher than the filter structure 5a, and the width of the limit block 5d is greater than the diameter of the through hole, which is used to limit the movement of the floating plate 8 above the limit block 5d, so that the mouth of the water suction pipe 6 can maintain a distance from the self-floating filter box 5 when it drops to the lowest point.

[0067] The preferred structures of the water suction pipe 6 and the backwash pipe 7 are as follows:

[0068] The water suction pipe 6 includes a first right angle elbow 6a and a first rubber tube 6b; one end of the first right angle elbow 6a extends into the self-floating filter box 5, the other end of the first right angle elbow 6a is connected to one end of the first rubber tube 6b, and the other end of the first rubber tube 6b is connected to the functional component.

[0069] The recoil pipe 7 includes a second right-angle bend pipe 7a and a second rubber tube 7b; one end of the second right-angle bend pipe 7a extends into the self-floating filter box 5, the other end of the second right-angle bend pipe 7a is connected to one end of the second rubber tube 7b, and the other end of the second rubber tube 7b is connected to the functional component.

[0070] The first rubber tube 6b and the second rubber tube 7b can produce a certain deformation, so as not to affect the floating and descending of the self-floating filter box 5, and the first right-angle bend tube 6a and the second right-angle bend tube 7a can keep the self-floating filter box 5 in a vertical position as much as possible, avoiding the movement of the floating platform 1 and causing the self-floating filter box 5 to be excessively skewed.

[0071] The present invention also provides a working method of a micro-nano aeration and oxygen enrichment device, which is used for the above-mentioned micro-nano aeration and oxygen enrichment device, and the steps include:

[0072] Equipment installation: first install all components except the self-floating filter box 5, then put the floating platform 1 on the water surface, then connect the water suction pipe 6 and the backwash pipe 7 to the self-floating filter box 5, then slowly put the self-floating filter box 5 into the water to complete the installation;

[0073] Oxygen-enriched operation: The gas compressor compresses the air and transmits it to the diaphragm pump. At the same time, the diaphragm pump pumps water. The diaphragm pump blades mix the air and water and transmit them to the aeration plate 3. The water mixed with air is output to the outside through the aeration plate 3.

[0074] Blockage processing: When the self-floating filter box 5 floats, it means that the filter structure 5a is blocked. At this time, the backwash function is turned on, the diaphragm pump is stopped, and the functional component transports gas or water to the self-floating filter box 5 through the backwash pipe 7 for a period of time. After backwashing, the diaphragm pump restarts pumping and continues to monitor the floating amount of the self-floating filter box 5; when the self-floating filter box 5 floats up to the set threshold number of times within the set time, it means that the filter structure 5a is seriously blocked, and backwashing cannot clean the filter structure 5a, causing it to be blocked multiple times within a period of time. At this time, an alarm should be sounded, and the alarm reminds that manual cleaning or replacement of the filter structure 5a is required.

[0075] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
