Description

Technical Field

[0001] The present application relates to the technical field of water treatment, and in particular to a micro-nano bubble aeration boat. Background Art

[0002] Micro-nano bubble aeration equipment can output micro-nano bubbles into the water, which helps to increase the dissolved oxygen content in the water, promote the decomposition and biodegradation of harmful substances in the water, and help improve the quality of the water. Therefore, micro-nano bubble aeration equipment is widely used in the water management of rivers and lakes.

[0003] The micro-nano bubble aeration equipment includes an aeration pipe fixed in the river channel and an aeration device installed on the bank, and the aeration device includes an inlet pipe for inputting water in the river channel, a micro-bubble generator, and an outlet pipe connected to the aeration pipe and used to output water with micro-nano bubbles. The micro-nano bubble aeration equipment passes the water in the river channel through the micro-bubble generator to enrich this part of water with micro-nano bubbles, and then discharges this part of water into the river channel through the aeration pipe, thereby increasing the dissolved oxygen content of the water in the river channel.

[0004] The above-mentioned micro-nano bubble aeration equipment is usually used in water treatment of rivers. When it is necessary to treat lakes and reservoirs, due to the large width of lakes and reservoirs, the local fixed aeration pipeline cannot effectively increase oxygen for the lake water, resulting in the above-mentioned micro-nano bubble aeration equipment being unsuitable for lakes with large width. Therefore, the inventor believes that a micro-nano bubble aeration boat that can be used for aeration of lakes and reservoirs is needed. Utility Model Content

[0005] In order to improve the problem that micro-nano bubble aeration equipment has limitations in improving the water quality of lakes and reservoirs, the present application provides a micro-nano bubble aeration boat.

[0006] The micro-nano bubble aeration boat provided in this application adopts the following technical solution:

[0007] A micro-nano bubble aeration boat comprises a power hull, on which a micro-bubble generator, a submersible pump and a diffuser are arranged; the micro-bubble generator comprises an aeration tank, an air outlet head arranged in the aeration tank and an air supply pump for supplying air to the air outlet head; the aeration tank has an inlet pipe and an outlet pipe; the submersible pump seals and penetrates the power hull, the water inlet of the submersible pump is located at the lower side of the power hull, and the water outlet of the submersible pump is connected to the inlet pipe; the diffuser is connected to the outlet pipe.

[0008] By adopting the above technical solution, the submersible pump can input the raw water into the microbubble generator, so that the raw water is transformed into water with micro-nano bubbles and discharged into the lake through the diffuser. The above technical solution integrates the submersible pump, microbubble generator and diffuser into the power hull, so that the micro-nano bubble aeration boat can output water with micro-nano bubbles while moving, realizing aeration treatment in lakes and reservoirs with large widths.

[0009] Optionally, the aeration tank is arranged in the middle of the power hull, and the submersible pump is arranged on one side of the aeration tank.

[0010] By adopting the above technical solution, since the aeration tank will be filled with water during operation and is relatively heavy, the aeration tank is arranged in the middle of the power hull, which helps the stability of the micro-nano bubble aeration boat after starting. In addition, since there is a pipeline connecting the aeration tank and the submersible pump, the submersible pump is arranged on one side of the aeration tank, which helps to control the length of the pipeline.

[0011] Optionally, the water inlet pipe is arranged at the top of the aeration tank, and the water outlet pipe is arranged at the bottom of the aeration tank; a partition plate is provided in the aeration tank to divide the inner cavity of the aeration tank, and the partition plate is provided with a cutting through hole penetrating the upper and lower surfaces; the air outlet head is arranged above the partition plate.

[0012] By adopting the above technical solution, the submersible pump passes the water into the aeration tank through the water inlet pipe, and the air supply pump pumps air into the aeration tank through the air outlet head to form small bubbles. Then the water continues to flow downward carrying the small bubbles. When passing through the partition plate, the cut through holes on the partition plate can further cut and break the small bubbles on the water, thereby forming more dense bubbles. The structural layout in the above aeration tank is conducive to the formation of micro-nano bubbles.

[0013] Optionally, the number of the partition plates is not less than three, and the apertures of the cut through holes on the partition plates gradually decrease from top to bottom along the height of the partition plates.

[0014] By adopting the above technical solution, at least three partition plates are set, and the cutting holes on the partition plates gradually decrease from top to bottom, the bubbles carried in the water body can be cut step by step to form more dense microbubbles, which is conducive to the formation of micro-nano bubbles.

[0015] Optionally, the air outlet head is an annular tube with a water hole formed in the middle, and the air outlet head has multiple air outlet holes arranged along the circumferential direction; the opening formed by the connection between the water inlet pipe and the aeration tank is directly opposite to the water hole.

[0016] By adopting the above technical solution, the structure and position setting of the air outlet head can ensure that when the air outlet hole of the air outlet head outputs bubbles, the bubbles can be carried downward by the water flow output by the water inlet pipe, so that the cutting effect of the bubbles on the cutting holes on the partition plate is more ideal.

[0017] Optionally, the power hull is provided with a lifting device for installing the diffuser and driving the diffuser to rise and fall.

[0018] By adopting the above technical solution, since the depth of lakes and reservoirs is generally deep, adjusting the depth of the diffuser through a lifting device is helpful for aerating water bodies at different depths, and helps to improve the aeration effect of the micro-nano bubble aeration boat on lakes and reservoirs.

[0019] Optionally, the lifting device includes a fixed bracket, a lifting hydraulic cylinder installed on the fixed bracket and arranged vertically downward, and a mounting seat installed on the end of the piston rod of the lifting hydraulic cylinder and used for mounting the diffuser.

[0020] By adopting the above technical solution, the specific structure of the lifting component is specifically disclosed, and the height of the diffuser is adjusted by the lifting hydraulic cylinder. The lifting driving force that can be output by the lifting hydraulic cylinder is ideal, and the driving stability is relatively ideal.

[0021] Optionally, four diffusers are provided on the power hull, and the diffusers are respectively arranged at the four corners of the power hull.

[0022] By adopting the above technical solution, the four diffusers can improve the aeration effect of the micro-nano aeration boat, and the four diffusers are respectively arranged at the four corners of the power hull, which can maintain the stability of the power hull.

[0023] Optionally, the diffuser has an aeration chamber, the top of the diffuser has a diffusion joint communicating with the aeration chamber, and the diffuser has a plurality of aeration joints communicating with the aeration chamber arranged circumferentially.

[0024] By adopting the above technical scheme, the structure of the diffuser is specifically disclosed, and the water flow with microbubbles enters the aeration chamber of the diffuser through the diffusion joint, and finally discharges from the diffuser through the aeration joint, thereby improving the diffusion angle of the water body with micro-nano bubbles, thereby helping to improve the aeration effect of the micro-nano bubble aeration boat on lakes and reservoirs.

[0025] Optionally, two submersible pumps are provided on the power hull, and the water outlets of the two submersible pumps are connected to the water inlet pipe of the aeration tank.

[0026] By adopting the above technical solution, the design of two submersible pumps can be used in a state of one in use and one in standby during the daily operation of the micro-nano bubble aeration boat, so that when one submersible pump is damaged, the other submersible pump can be used to ensure the normal aeration work of the micro-nano bubble aeration boat. In addition, by adopting two submersible pumps, the maximum flow rate of the water body with micro-nano bubbles output by the micro-nano bubble aeration boat is more ideal.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

In this embodiment, the power hull 1 is a boat driven by a diesel engine.

[0040] Reference Figure 1 and Figure 2 The aeration device includes a submersible pump 2, a microbubble generator and a plurality of diffusers 6. The principle of the aeration device is that the submersible pump 2 introduces water into the microbubble generator, and the microbubble generator aerates the water so that micro-nano bubbles can be present in the water, and then the water with micro-nano bubbles is discharged into the lake reservoir through the diffuser 6.

[0041] Reference Figure 2 The aeration device has two submersible pumps 2. The two submersible pumps 2 are arranged in parallel and are both sealed to penetrate the power hull 1. When the submersible pumps 2 and the power hull 1 are assembled, two through holes that penetrate the power hull 1 and match the size of the submersible pumps 2 are opened at the bottom of the power hull 1. After that, the submersible pumps 2 are arranged in the through holes and fixed to the through holes by welding.

Among them, an exhaust valve is set on the top of the aeration tank 3. When the submersible pump 2 is used to fill the aeration tank 3 with water, the gas originally in the aeration tank 3 will be discharged from the aeration tank through the exhaust valve, thereby achieving the effect of emptying the gas in the aeration tank 3.

The aperture of the cutting holes 33 on the partition plates 32 gradually decreases from top to bottom along the height of the partition plates 32. The structural arrangement of the plurality of partition plates 32 and the cutting holes 33 enables the bubbles carried by the water flow to be cut and broken step by step when passing through the partition plates 32, thereby obtaining finer bubbles.

In order to provide water with microbubbles to the four diffusers 6 at the same time, an aeration pipeline 7 is also arranged on the micro-nano bubble aeration boat. The aeration pipeline 7 is H-shaped as a whole and includes a long pipeline 71 arranged on both sides of the power hull 1 and a short pipeline 72 connecting the two long pipelines 71. Both ends of the long pipeline 71 are connected to an aeration hose 73 for communicating with the diffusion joint 62 of the diffuser 6.
