Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to a wetland water purification device. Background Technology

[0002] Oxygen deficiency is a common characteristic of polluted water bodies, especially black and odorous water bodies. Restoring the oxygen consumption / reoxygenation balance of water bodies and increasing the dissolved oxygen content are the primary goals of water environment management and aquatic ecosystem restoration.

[0003] There are various methods for oxygenating water bodies, such as oxygenation through plant photosynthesis, hydraulic oxygenation, oxygenation by adding chemical agents, and aeration. Among these, aeration can rapidly increase dissolved oxygen in water, oxidize water pollutants, and also has landscaping, sediment restoration, and algae suppression effects, making it the main method for oxygenating water bodies.

[0004] The existing oxygenation method mainly involves placing an aeration pipe network at the bottom of the water body and using a blower to deliver compressed air to the aeration pipe network. The aeration pipe network outputs tiny bubbles in the water body, causing the oxygen in the compressed air to dissolve in the water body, thereby increasing the oxygen content in the water body.

[0005] However, the existing oxygenation methods are not ideal when applied to wetlands. The main reasons are that wetlands are shallow, the distance between the aeration pipe network and the water surface is short, and after the aeration pipe network generates bubbles, the bubbles move directly upward to the water surface, resulting in a short contact time between the bubbles and the water and low oxygenation efficiency. Summary of the Invention

[0006] In order to address the shortcomings of existing oxygenation methods in wetlands where the effect is not ideal, this invention proposes a wetland water purification device that increases the time that air bubbles spend in the water, thereby improving oxygenation efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wetland water purification device includes: a floating mechanism, an aeration mechanism, and a bubble dispersion mechanism; the floating mechanism includes a guide cylinder, which can be vertically suspended in the wetland water, with its upper end below the water surface, and a microbial growth layer is provided on the wall of the guide cylinder; the aeration mechanism is located below the guide cylinder and can output bubbles to the guide cylinder through the water; the bubble dispersion mechanism includes several propellers, and the guide cylinder has several mounting ports arranged circumferentially. The propellers are mounted on the guide cylinder in a circular array around the axis of the guide cylinder through the mounting ports. The input end of the propeller is located inside the guide cylinder to extract water mixed with bubbles inside the guide cylinder, and the output end of the propeller is located outside the guide cylinder and is inclined downward to discharge the water mixed with bubbles to the side of the guide cylinder.

[0009] Through the above settings, firstly, the aeration mechanism can generate bubbles in the water, thereby creating an aerobic environment in the water, which facilitates the decomposition of pollutants in the water by microorganisms generated in the microbial growth layer; secondly, the propeller can discharge the bubbles in the guide tube to the outside of the guide tube, increasing the movement path of the bubbles in the water, thereby increasing the residence time of the bubbles in the water and improving the oxygenation effect; thirdly, the propeller can radiate the water mixed with bubbles to the periphery of the guide tube, promoting water flow and further increasing the oxygenation efficiency.

[0010] Furthermore, all thrusters rotate at the same speed, and the output direction of the thrusters does not pass through the axis of the guide cylinder, so that the thrusters can drive the guide cylinder to rotate when they are running.

[0011] With the above settings, firstly, horizontal movement of the guide cylinder can be prevented; secondly, the propeller can drive the guide cylinder to rotate so that the water rich in bubbles is evenly discharged to the periphery of the guide cylinder.

[0012] Furthermore, the floating mechanism also includes: a floating body that can float on the water surface, and a connecting rod; the upper end of the guide tube is installed below the floating body via the connecting rod.

[0013] With the above setup, the guide tube is suspended in the water via the connecting rod and the floating body.

[0014] Furthermore, the aeration mechanism includes: a foaming component, a hose, and an air blower; the foaming component includes a base plate and an aeration pipe network, the base plate is located below the guide cylinder, and the aeration pipe network is installed on the upper side of the base plate; the air blower is connected to the aeration pipe network through a hose to deliver compressed air to the aeration pipe network.

[0015] With the above setup, the blower blows air into the aeration network through a hose, so that the aeration network outputs bubbles.

[0016] Furthermore, the purification device also includes a lifting mechanism, which comprises: a support frame, a winch, a first cable, an underwater sliding ring, and a second cable; the support frame is fixedly connected to the floating body; the winch is mounted on the support frame; one end of the first cable is wound around the winch and electrically connected to the thruster and the winch; the underwater sliding ring is vertically mounted on the base plate, and the lower end of the first cable is connected to the underwater sliding ring, allowing the winch to drive the base plate up and down via the first cable; the second cable supplies power to the thruster via the underwater sliding ring and the first cable.

[0017] The above setup achieves the following objectives: first, it facilitates the placement of the purification device; second, it allows the purification device to be adapted to wetlands of different water depths; third, it facilitates the storage of the purification device; and fourth, it further increases the stability of the guide tube in the water.

[0018] Furthermore, the base plate is circular, and the bubble-generating assembly also includes a gravity ball and several support feet. The support feet are installed circumferentially on the underside of the base plate, and the gravity ball is installed below the center of the base plate so that the center of gravity of the bubble-generating assembly is located below the center of the base plate. The underwater sliding ring is installed on the center of the base plate so that the base plate is basically horizontal when it is suspended in the water.

[0019] With the above settings, the bubble assembly remains basically horizontal when moving up and down in the water.

[0020] Furthermore, the aeration network includes: a main pipe and several aeration pipes; the main pipe is installed on the upper side of the base plate and is set along the diameter of the base plate, with one end of the main pipe connected to a flexible hose; several aeration pipes are symmetrically distributed on opposite sides of the main pipe, the aeration pipes are arc-shaped, and the center of all aeration pipes is close to the center of the base plate, with both ends of the aeration pipe connected to the main pipe; the foaming assembly also includes a mounting base, which is installed on the base plate, the main pipe passes through the mounting base, and an underwater sliding ring is installed on the upper side of the mounting base.

[0024] Figure 3 This is a schematic diagram of the purification device during aeration, as shown in the embodiment. Detailed Implementation

[0025] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0026] See Figures 1 to 3 A wetland water purification device includes: a floating mechanism 3, an aeration mechanism 4, and a bubble dispersion mechanism 5; the floating mechanism 3 includes a guide cylinder 31, which can be vertically suspended in the water of the wetland, and the upper end of the guide cylinder 31 is lower than the water surface, and a microbial generation layer 311 is provided on the wall of the guide cylinder 31; the aeration mechanism 4 is located below the guide cylinder 31 and can output bubbles to the guide cylinder 31 through the water; the bubble dispersion mechanism 5 includes a plurality of propellers 51, and the guide cylinder 31 is provided with a plurality of mounting ports 312 along the circumference. The propellers 51 are mounted on the guide cylinder 31 in a ring array around the axis of the guide cylinder 31 through the mounting ports 312. The input end of the propeller 51 is located inside the guide cylinder 31 to extract water mixed with bubbles in the guide cylinder 31, and the output end of the propeller 51 is located outside the guide cylinder 31 and is inclined downward to discharge water mixed with bubbles to the side of the guide cylinder 31.

[0027] Through the above settings, firstly, the aeration mechanism 4 can generate bubbles in the water, thereby creating an aerobic environment in the water, which facilitates the decomposition of pollutants in the water by the microorganisms generated in the microbial generation layer 311; secondly, the propeller 51 can discharge the bubbles in the guide cylinder 31 to the outside of the guide cylinder 31, increasing the movement path of the bubbles in the water, thereby increasing the residence time of the bubbles in the water and improving the oxygenation effect; thirdly, the propeller 51 can radiate the water mixed with bubbles to the periphery of the guide cylinder 31, promoting water flow and further increasing the oxygenation efficiency.

[0028] In this application, the guide cylinder 31 is cylindrical and vertically suspended in the wetland water, with minimal vertical movement. A microbial growth layer 311 is disposed on the inner and outer walls of the guide cylinder 31. The microbial growth layer 311 can contain the same species of bacteria or multiple species. The aeration mechanism 4 can be disposed at the bottom of the wetland water. The aeration mechanism 4 emits microbubbles that rise in the water and enter the guide cylinder 31 from the bottom. The propeller 51 can be purchased commercially and installed in the mounting port 312 with bolts. It draws water from the input end and sprays water from the output end. (See [reference]). Figure 3 Water mixed with air bubbles is drawn away from the guide cylinder 31 by the propeller 51, and then the output end of the propeller 51 discharges the water mixed with air bubbles. When the output end of the propeller 51 is tilted downward, the air bubbles move downward in the water first and then float to the surface. The movement path of the air bubbles is longer, that is, the air bubbles stay in the water for a longer time. After the oxygen in the air bubbles dissolves in the water, the water near the guide cylinder 31 is in an aerobic state, which facilitates the decomposition of pollutants in the water by microorganisms on the microbial incubation layer 311. When the upper end of the guide cylinder 31 is below the water surface, water in the water body can enter the guide cylinder 31 through the upper end of the guide cylinder 31, preventing the water intake speed at the lower end of the guide cylinder 31 from being too fast, and thus preventing the air bubbles below the guide cylinder 31 from rising too fast.

[0029] As one implementation method, all thrusters 51 rotate at the same speed, and the output direction of thrusters 51 does not pass through the axis of guide cylinder 31, so that when thrusters 51 are running, they can drive guide cylinder 31 to rotate.

[0030] With the above settings, firstly, the guide cylinder 31 can be prevented from moving horizontally; secondly, the propeller 51 can drive the guide cylinder 31 to rotate so that the water rich in bubbles is evenly discharged to the periphery of the guide cylinder 31.

[0031] The purification device of this application is used in wetlands where the water flow is very small. Without external force, the guide cylinder 31 will not move horizontally. When all the thrusters 51 are running at the same speed, the thrust of each thruster 51 on the water is basically the same. Since the thrusters 51 are arranged in a ring array on the guide cylinder 31, the resultant external force of the thrusters 51 on the guide cylinder 31 causes the guide cylinder 31 to rotate around the axis of the guide cylinder 31, and the guide cylinder 31 will not move horizontally.

[0032] As one implementation, the floating mechanism 3 also includes: a floating body 32 that can float on the water surface, and a connecting rod 33; the upper end of the guide cylinder 31 is installed below the floating body 32 via the connecting rod 33.

[0033] With the above configuration, the guide cylinder 31 is suspended in the water via the connecting rod 33 and the float 32.

[0034] In this application, the float 32 is configured as a hollow ring structure, which can float horizontally on the water surface. The center of the float 32 is located on the axis of the guide cylinder 31, so that the guide cylinder 31 has good stability.

[0035] As one implementation method, the aeration mechanism 4 includes: a foaming component 41, a hose 42, and an air blower (not shown in the figure); the foaming component 41 includes a base plate 411 and an aeration pipe network, the base plate 411 is located below the guide cylinder 31, and the aeration pipe network is installed on the upper side of the base plate 411; the air blower is connected to the aeration pipe network through the hose 42 to deliver compressed air to the aeration pipe network.

[0036] With the above setup, the blower blows air into the aeration network through the hose 42, so that the aeration network outputs bubbles.

[0037] In this application, the base plate 411 is used to support the aeration pipe network, which is provided with multiple air holes. The blower and hose 42 can be purchased from the market. The blower is placed on the shore. After being powered on, the blower delivers compressed gas to the aeration pipe network through the hose 42, and the air holes of the aeration pipe network output bubbles.

[0038] As one implementation method, the purification device also includes a lifting mechanism 6, which includes: a bracket 61, a winch 62, a first cable 63, an underwater sliding ring 64, and a second cable 65; the bracket 61 is fixedly connected to the floating body 32; the winch 62 is mounted on the bracket 61; one end of the first cable 63 is wound around the winch 62 and electrically connected to the thruster 51 and the winch 62; the underwater sliding ring 64 is vertically mounted on the base plate 411, and the lower end of the first cable 63 is connected to the underwater sliding ring 64, so that the winch 62 can drive the base plate 411 to move up and down through the first cable 63; the second cable 65 supplies power to the thruster 51 through the underwater sliding ring 64 and the first cable 63.

[0039] The above settings achieve the following: first, facilitate the arrangement of the purification device; second, enable the purification device to adapt to wetlands with different water depths; third, facilitate the storage of the purification device; and fourth, further increase the stability of the guide cylinder 31 in the water.

[0040] In this application, the length of the guide cylinder 31 is less than the water depth of the wetland. Initially, the bubble assembly is close to the lower end of the guide cylinder 31. The operator travels by boat to the deployment point of the purification device, and then the floating mechanism 3 and the bubble assembly are placed into the water. The bubble assembly does not contact the bottom of the water to prevent it from being damaged. Then, the winch 62 slowly releases the first cable 63, and the bubble generating assembly 41 slowly moves downward under the action of gravity to contact the bottom of the water, maximizing the distance between the bubble generating assembly 41 and the water surface. During the aeration process, the first cable 63 serves as a conductor. On the other hand, the first cable 63 is basically vertical, which further restricts the horizontal movement of the guide cylinder 31. In addition, the underwater sliding ring 64 can be purchased from the market and can be used in water. When the guide cylinder 31 rotates, the second cable 65 is always electrically connected to the first cable 63 through the underwater sliding ring 64. When the purification device is used up and needs to be retracted, when the winch 62 winds the first cable 63, the bubbling component 41 moves upward and detaches from the bottom of the water. Then the operator pulls the hose 42 on the shore to pull the purification device ashore, without the need to go by boat for storage.

[0041] In one implementation, the base plate 411 is circular, and the bubble-generating assembly 41 also includes a gravity ball 412 and several support feet 413. The support feet 413 are installed circumferentially on the lower side of the base plate 411, and the gravity ball 412 is installed below the center of the base plate 411 so that the center of gravity of the bubble-generating assembly 41 is located below the center of the base plate 411. The underwater sliding ring 64 is installed on the center of the base plate 411 so that the base plate 411 is basically horizontal when it is suspended in the water.

[0042] With the above settings, the bubble assembly remains basically horizontal when moving up and down in the water.

[0043] When the bubble assembly is in water, the first cable 63 applies an upward force to the base plate 411, and the gravity ball 412 applies a downward force to the base plate 411. The two forces are basically on the same straight line, making the base plate 411 basically horizontal in the water. The lower end of the support foot 413 is flush with the lower side of the gravity ball 412. After the bubble assembly contacts the bottom of the water, the support foot 413 can stably support the base plate 411. When encountering a soft bottom, the support foot 413 can insert into the bottom of the water, increasing the stability of the bubble assembly at the bottom of the water.

[0044] As one implementation method, the aeration pipe network includes: a main pipe 414 and several aeration pipes 415; the main pipe 414 is installed on the upper side of the base plate 411 and is arranged along the diameter of the base plate 411, and one end of the main pipe 414 is connected to the hose 42; several aeration pipes 415 are symmetrically distributed on opposite sides of the main pipe 414, the aeration pipes 415 are arc-shaped, and the center of all aeration pipes 415 is close to the center of the base plate 411, and both ends of the aeration pipes 415 are connected to the main pipe 414; the foaming component 41 also includes a mounting base 416, the mounting base 416 is installed on the base plate 411, the main pipe 414 passes through the mounting base 416, and the underwater sliding ring 64 is installed on the upper side of the mounting base 416.

[0045] With the above setup, the blower outputs bubbles through hose 42, main pipe 414 and aeration pipe 415.

[0046] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
