Description

Technical Field

[0001] This invention relates to the field of water quality remediation technology, and in particular to an aerator for self-lifting internal circulation water. Background Technology

[0002] Currently, many water purification technologies focus on treating pollutants on the water surface, but they struggle to address pollutants in the lower parts of the water, especially those at the bottom. Dissolved oxygen levels at the bottom of water bodies are typically very low, further promoting the release of pollutants from bottom sediments. For deep water, existing equipment cannot directly reach the bottom for treatment. Therefore, there is an urgent need for a purification device to clean water from the bottom of water bodies.

[0003] The invention disclosed in CN218232068U is a deep-water self-lifting aerator, including an aeration lifting mechanism and an aeration system. The aeration lifting mechanism includes an aeration water inlet cylinder, an aerator, a water seal sleeve, a sealing cylinder, and an anchor block. The lower end of the aeration water inlet cylinder is provided with a lower sealing plate, and a middle sealing plate with a guide tube is provided in the lower part. A one-way valve is provided on the guide tube. The aeration water inlet cylinder is provided with a water suction pipe, and the aerator is placed above the middle sealing plate. The lower end of the water seal sleeve is sealed and fixed to the aeration water inlet cylinder, and the upper end is provided with an upper sealing plate. An air guide pipe is provided in the lower part. The water inlet pipe with a one-way valve passes through the upper sealing plate, and the lower end is lower than the lower end of the water seal sleeve. The anchor block is connected to the lower end of the aeration water inlet cylinder. The sealing cylinder fixes the aeration water inlet cylinder. A hose is connected to the upper end of the water inlet pipe. The upper end of the hose has a water distribution head with water distribution holes. The aeration system includes a solar panel, a battery, and an aerator placed on a floating plate. This invention can aerate water at the bottom of deep water bodies, and the high pressure can improve the oxygen transfer rate. However, the aeration lifting mechanism is located at the bottom of the water body, and the working environment has a high pressure, which places high demands on the performance of the aeration equipment and increases costs. The one-way valves on the conduit and the water inlet pipe are easily blocked by impurities in the water, which can prevent the equipment from working properly and seriously affect the purification effect. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an aerator for a self-lifting internal circulation water body.

[0005] To solve the above-mentioned technical problems, the present invention provides a self-lifting aerator for internally circulating water, comprising an aeration lifting mechanism and an aeration system. The aeration lifting mechanism includes a sealed tank, an outlet pipe, a U-shaped pipe, a check pipe, an aeration head, and an inlet head. The sealed tank is a hollow, sealed space. The outlet pipe passes through the upper end of the sealed tank. One end of the U-shaped pipe is connected to the outlet pipe and is located inside the sealed tank. The inlet of the outlet pipe inside the sealed tank is lower than the lowest point of the U-shaped pipe. The check pipe passes through the bottom of the sealed tank, and its upper end is higher than the other end of the U-shaped pipe. The aeration head is placed at the bottom of the sealed tank. A vent pipe connecting the aeration head passes through the sealed tank and connects to the aeration system. The sealed tank is fixed below a float plate, which has an opening. The outlet pipe passes through the opening, and its upper outlet is higher than the float plate. The inlet head is connected to the lower end of the check pipe via a connecting hose. The aeration system is fixed to the float plate.

[0006] The aforementioned aeration system includes a solar panel, an aerator, and a support frame. The solar panel and the aerator are placed on the support frame. The solar panel is connected to the aerator via an electric wire, and the air pipe is connected to the aerator. The support frame is placed on a floating plate.

[0007] A float is installed at the top of the aforementioned water inlet head, and a water inlet pipe with a grid head is fixed below the float. A connecting hose is connected to the water inlet pipe, and the water inlet pipe is connected to a weight block by a pull rope.

[0008] The advantages of this invention compared to the prior art are as follows: the main aeration lifting mechanism of this invention is placed near the water surface, where the working pressure of the environment is very low, the requirements for equipment are low, and the cost of aeration equipment is greatly reduced; the water inlet head is suspended at a certain height at the bottom of the water body, which can ensure that the bottom water moves upward through the device, while avoiding disturbance of the bottom sediment; by changing the distance between the water inlet head and the sealed tank, the path of the upper and lower internal circulating water bodies is changed, and the vertical and horizontal circulation is achieved by self-lifting the water body.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 —5.

[0015] A self-lifting aerator for internally circulating water includes an aeration lifting mechanism and an aeration system. The aeration lifting mechanism includes a sealed tank 101, an outlet pipe 102, a U-shaped pipe 103, a check pipe 104, an aeration head 105, and an inlet head 106. The sealed tank 101 is a hollow, sealed space. The outlet pipe 102 passes through the upper end of the sealed tank 101. One end of the U-shaped pipe 103 is connected to the outlet pipe 102 and is located inside the sealed tank 101. The inlet 1021 of the outlet pipe 102 inside the sealed tank 101 is lower than the lowest point of the U-shaped pipe 103. The check pipe 104 passes through the bottom of the sealed tank 101, and its upper port 1041 is higher than the inlet of the other end of the U-shaped pipe 103. The aeration head 105 is located at the bottom inside the sealed tank 101 and is connected to... The air vent 1051 of the aeration head 105 passes through the sealed barrel 101. The water inlet head 106 is connected to the lower end of the check pipe 104 through the connecting hose 1061. The aeration system includes a solar panel 201, an aerator 202, and a bracket 203. The solar panel 201 and the aerator 202 are placed on the bracket 203. The solar panel 201 is connected to the aerator 202 through the wire 204. The air vent 1051 is connected to the aerator 202. The bracket 203 is placed on the float 205. The sealed barrel 101 is fixed below the float 205. The float 205 has an opening. The water outlet pipe 102 passes through the opening. The water outlet 1022 at the top of the water outlet pipe 102 is higher than the float 205. A float 1062 is provided on the upper part of the water inlet head 106. A water inlet pipe 1064 with a grid head 1063 is fixed below the float 1062. A connecting hose 1061 is connected to the water inlet pipe 1064. The water inlet pipe 1064 is connected to the weight block 1066 by a pull rope 1065.

[0016] The working process of this invention is as follows.

[0017] The device is placed in the water body to be purified. The float 205 floats on the water surface, the sealed bucket 101 is below the water surface, and the support 203 is above the water surface. The weight block 1066 is at the bottom of the water body under the action of gravity. The buoyancy of the float 1062 causes the screen head 1063 and the water inlet pipe 1064 to float upward. At the same time, under the action of the pull rope 1065, the screen head 1063 is suspended in a fixed position above the bottom of the water body.

[0018] Before the aeration lifting mechanism is started, the water level in the sealed tank 101 is between the upper port 1041 of the check pipe 104 and the inlet of the U-shaped pipe 103.

[0019] The water discharge stage of the aeration lifting mechanism. The aerator 202 is started, and the gas is transmitted to the aeration head 105 through the air pipe 1051, forming fine bubbles that are introduced into the sealed tank 101. As the fine bubbles rise, they come into full contact with the water, allowing the oxygen in the air to fully dissolve into the water. The bubbles rise to the top of the sealed tank 101, increasing the gas volume and pressure at the top. As the air pressure increases, the water in the sealed container 101 is transported to the surface of the water body through the inlet 1021 of the outlet pipe 102 and the inlet of the U-shaped pipe 103. The liquid level in the check pipe 104 is lower than the liquid level in the sealed container 101. Since the upper port 1041 of the check pipe 104 is higher than the liquid level in the sealed container 101, the water in the sealed container 101 will not be discharged through the check pipe 104, thus achieving the backflow prevention effect. When the liquid level in the sealed container 101 drops below the inlet of the U-shaped pipe 103, the water in the sealed container 101 is mainly transported to the surface of the water body through the inlet 1021 of the outlet pipe 102. As the air pressure in the sealed container 101 increases, the air pressure in the check pipe 104 will squeeze some of the water in the pipe downwards and then squeeze it out of the water body through the inlet head 106. The liquid level in the check pipe 104 is lower than the liquid level in the sealed container 101.

[0020] The water intake stage of the aeration lifting mechanism: When the liquid level in the U-tube 103 drops to its bottom position, the air pressure inside the sealed tank 101 is relatively high. The gas in the U-tube 103 bypasses its bottom and then quickly rises and is discharged to the water surface through the outlet pipe 102. Then, the air pressure inside the sealed tank 101 drops rapidly. Under the action of pressure difference, the water at the bottom of the water body enters the connecting hose 1061 through the inlet head 106, and is then transported to the check pipe 104. The upper port 1041 of the check pipe 104 replenishes the sealed tank 101 until the liquid level in the sealed tank 101 returns to the state before the aeration lifting mechanism is started. This cycle continuously transports the aerated water from the bottom to the water surface.

[0021] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
