[0047] Figure 1 and Figure 2 is a gas lift aerator 100 according to an embodiment of the present disclosure,
[0048] like Figures 1 to 3 As shown, the gas lift aerator 100 comprises:
[0049] At least three vertical poles 110, wherein the first ends 111 of the vertical poles 110 are used to be fixed on the bottom of the water body, and the second ends 112 of the vertical poles 110 are exposed from the surface of the water body;
[0050] The mounting frame 120 includes a plurality of first connecting rods 121 detachably connected to the vertical rods 110, the mounting frame 120 is arranged parallel to the surface of the water body, and the mounting frame 120 is located in the water body;
[0051] an aeration grid 130, the aeration grid 130 being disposed on the mounting frame 120, the aeration grid 130 comprising an aeration hose array consisting of a plurality of aeration hoses 131, the tube walls of the aeration hoses 131 being provided with pores (not shown in the figure) communicating with the inside and outside of the aeration hoses 131, the aeration grid 130 being located in the water body;
[0052] The blower 140 and the air supply pipe 150 are arranged on the surface of the water body. The blower 140 inputs gas to the aeration hose 131 of the aeration grid 130 through the air supply pipe 150, and the gas is discharged into the water body from the pores of the aeration hose 131.
[0053] In a possible implementation, the pole 110 may be a metal pipe, for example, a galvanized pipe or a stainless steel pipe.
[0054] The first end 111 of the vertical pole 110 can be fixed to the bottom of the water body by inserting into the mud at the bottom of the water body.
[0055] In a possible implementation, the first end 111 of the pole 110 may be provided with a barb device, etc., and after the first end 111 of the pole 110 is inserted into the mud at the bottom of the water body, the first end 111 is fixed to the bottom of the water body.
[0056] In a possible implementation, a first connecting rod 121 can be detachably connected to two upright poles 110 .
[0057] In a possible implementation, the first connecting rod 121 may be connected to the vertical rod 110 by means of bolts or other connection methods.
[0058] For example, the three vertical poles 110 can be arranged in a triangle, that is, the three vertical poles 110 are fixed to the bottom of the water body as the three vertices of the triangle, and the three first connecting rods 121 can be used as the sides of the triangle to connect the three vertical poles 110. The three first connecting rods 121 constitute a mounting frame 120 for setting the aeration grid 130.
[0059] In a possible implementation, the diameter of the gap may range from 25 micrometers to 100 micrometers.
[0060] In a possible implementation, the aeration hose 131 may be made of a thermoplastic material, and the aeration hose 131 may be punched to form pores on the wall of the aeration hose 131 .
[0061] In a possible implementation, the aeration hose 131 can be made of a thermoplastic adhesive material matrix and thermosetting polymer particles. The thermoplastic adhesive material bonds the thermosetting polymer particles to form the wall of the aeration hose 131, and forms pores between the thermosetting polymer particles. The pores can refine the exhausted air so that the exhausted air forms fine bubbles. Generally, the smaller the bubbles, the better the oxygenation effect.
[0062] In a possible implementation, the aeration grid 130 needs to be at a predetermined distance from the bottom of the water body.
[0063] In a possible implementation, the blower 140 may be disposed at the second end 112 of any upright pole 110 .
[0064] In a possible implementation, the blower 140 may be disposed between the vertical poles 110 and located on a second connecting rod 170 on the surface of the water body.
[0065] In a possible implementation, the blower 140 may include a housing, a motor, a fan blade, a control panel and an outer cover. The housing may be cylindrical. The control panel, the fan blade and the motor are sequentially arranged inside the housing from top to bottom. The motor drives the fan blade to draw air from the top of the housing, and the drawn air passes through the control panel and the motor in turn to achieve heat dissipation of the control panel and the motor. The lower part of the housing is connected to the air supply pipe 150 to discharge the drawn air to the air supply pipe 150. The housing may be cylindrical, and an outer cover is provided on the upper part of the housing, the outer cover having a cover wall parallel to the side wall of the cylinder, and a gap for air to enter between the side wall of the cylinder and the cover wall. The outer cover can prevent rainwater from entering the interior of the housing.
[0066] In a possible implementation, the aeration grid 130 may be arranged based on the shape of the mounting frame 120 . The shape of the aeration grid 130 may also be different from that of the mounting frame 120 .
[0067] The blower 140 can blow gas, such as air, into the air supply pipe 150, and input the gas into the aeration hose 131 through the air supply pipe 150. The air is discharged into the water body through the pores of the aeration hose 131 to oxygenate the water body.
[0068] In a possible implementation, the air supply pipe 150 may be a hose, such as a corrugated tube.
[0069] Thus, on the one hand, the aeration grid 130 aerates the water body in the water body, so that the deep water body can also be directly oxygenated, thereby improving the oxygenation effect. On the other hand, the air lift aerator 100 has a simple structure, no longer requires a floating ship, reduces the transportation volume, and saves material costs and transportation costs.
[0070] In some embodiments, the air lift aerator 100 includes four upright poles 110 disposed at the four corners of a rectangle;
[0071] The rectangular parallelepiped formed by the four vertical poles 110 has water retaining side walls 160 disposed on three first sides of the four sides perpendicular to the surface of the water body;
[0072] The aeration grid 130 is disposed in a rectangular parallelepiped surrounded by the four vertical poles 110;
[0073] The second side surface among the four side surfaces, which is not provided with the water retaining side wall 160 , is used to discharge a water-gas mixture, which is composed of water and gas discharged from the pores of the aeration hose 131 .
[0074] In a possible implementation, the water retaining side wall 160 may be made of a water-impermeable material.
[0075] In a possible implementation, the water retaining side wall 160 may be made of a waterproof cloth, and the waterproof cloth is fixed on the vertical pole 110 to form the water retaining side wall 160 .
[0076] At the bottom of the cuboid surrounded by the four vertical poles 110, the aeration grid 130 mixes air bubbles and water. The mixture floats to the surface of the water because of its reduced density. After the mixture floats to the surface, the bubbles are discharged from the water surface, and the water in the mixture sinks. The aeration grid 130 continuously provides the mixture from the bottom to the water surface. The sinking water plus the subsequent rising mixture increases the pressure in the cuboid, thereby discharging the water-gas mixture in the cuboid from the second side. Since the aeration grid 130 continuously generates bubbles, the second side continuously discharges the water-gas mixture outside the cuboid. This promotes the flow of the water body and diffuses the oxygen-rich water to a farther distance, promoting the oxygenation effect of the water body.
[0077] In some embodiments, the height of the above-water portion of the water retaining side wall 160 is greater than the first height; and / or
[0078] The underwater portion of the water retaining side wall 160 is axially spaced from the aeration grid 130 by a distance greater than the second height.
[0079] The above-water portion of the water-retaining side wall 160 needs to block the rising water-gas mixture so that the water-gas mixture can only be discharged from the second side, thereby increasing the discharge flow rate of the water-gas mixture and promoting the oxygenation effect of the water body.
[0080] In one possible implementation, the first height may be 15 centimeters.
[0081] In one possible implementation, when the water-gas mixture is discharged from the second side, a large amount of water needs to be added to the rectangular body surrounded by the four vertical poles 110. Therefore, water supply can be left between the water retaining side wall 160 and the aeration grid 130 to enter the rectangular body surrounded by the four vertical poles 110, so that more water can be combined with the gas to promote the oxygenation effect of the water body.
[0082] In some embodiments, a second connecting rod 170 is disposed between two opposite vertical rods 110 on the second side surface, and the blower 140 is disposed on the second connecting rod 170 .
[0083] The second connecting rod 170 may be made of metal material and may be subjected to anti-corrosion treatment.
[0084] For example, the second connecting rod 170 may be a galvanized metal rod.
[0085] The blower 140 may be detachably mounted on the second connecting rod 170 to facilitate disassembly and installation.
[0086] In some embodiments, the second connecting rod 170 is provided with a connecting pipe 171 , one end of the connecting pipe 171 is detachably connected to the blower 140 , and the other end of the connecting pipe 171 is detachably connected to the air supply pipe 150 .
[0087] The second connecting rod 170 may be provided with a connecting pipe 171 fixedly connected to the second connecting rod 170. For example, the connecting pipe 171 may be welded to the second connecting rod 170.
[0088] The air outlet of the blower 140 may be connected to one end of the connecting pipe 171. For example, the air outlet of the blower 140 may be connected to one end of the connecting pipe 171 by threaded fit.
[0089] The air supply pipe 150 can be sleeved on the other end of the connecting pipe 171 and locked and sealed by a clamp.
[0090] In some embodiments, two vertical rods 110 opposite to the second side surface are respectively sleeved with sliding sleeves 172, and the sliding sleeves 172 can move along the axial direction of the corresponding vertical rods 110, and the second connecting rod 170 is connected to the sliding sleeves 172;
[0091] The sliding sleeve 172 is provided with a first locking component (not shown in the figure) for locking the sliding sleeve 172 on the corresponding upright pole 110 .
[0092] In one possible implementation, the sliding sleeve 172 includes a collar sleeved on the cylindrical pole 110;
[0093] The first locking component includes a bolt penetrating the side wall of the collar. When the bolt is tightened, the top of the bolt abuts against the outer wall of the vertical rod 110 to prevent the sliding sleeve 172 from moving.
[0094] The distance between the blower 140 and the aeration grid 130 can be adjusted by the sliding sleeve 172, and the disassembly of the second connecting rod 170 is also facilitated.
[0095] In some embodiments, the aeration grid 130 further includes a pipe 132, and the pipe 132 is configured as a rectangular frame;
[0096] The aeration hose 131 is connected to a set of opposite pipes 132 in the rectangle;
[0097] The air supply pipe 150 is connected to the pipeline 132 , and gas is input to the aeration hose 131 through the pipeline 132 .
[0098] The pipe 132 can serve as a frame of the aeration grid 130. The pipes 132 on four sides of the rectangular frame can be connected. The air supply pipe 150 can be connected to the pipe 132 to input air into the pipe 132.
[0099] In a possible implementation, an aeration hose 131 is provided between the pipes 132 on the two sides of the rectangular frame with a longer length, and the pipe 132 on the side of the rectangular frame with a shorter length is connected to the air supply pipe 150. The air supply pipe 150 can be connected to the middle of the pipe 132 on the side of the rectangular frame with a shorter length. In this way, the blower 140 can evenly pressurize the aeration hose 131, so that the air discharge from the aeration hose 131 is more even.
[0100] In some embodiments, the first connecting rod 121 is provided with a mounting surface (not shown in the figure) parallel to the surface of the water body, and the pipe 132 of the aeration grid 130 is erected on the mounting surface.
[0101] For example, the first connecting rod 121 can be an angle iron, and the four angle irons are surrounded by the four vertical rods 110 to form a mounting frame 120 in a rectangular parallelepiped, and a surface of each of the four angle irons constitutes a mounting surface. The pipe 132 of the aeration grid 130 can be mounted on the mounting surface. For example, the pipe 132 of the aeration grid 130 can be mounted on the mounting surface by tying with a cable tie.
[0102] In some embodiments, the mounting frame 120 further includes a moving component 122 disposed on the vertical pole 110 and capable of moving axially along the vertical pole 110 , and the first connecting rod 121 is connected to the vertical pole 110 via the moving component 122 ;
[0103] The mounting frame 120 further includes a second locking component (not shown in the figure) for locking the moving component 122 on the vertical pole 110 .
[0104] In a possible implementation, the pole 110 may include a track for the moving component 122 to move. For example, the pole 110 itself may be a track.
[0105] The moving component 122 moves axially along the vertical pole 110 to realize the movement of the mounting frame 120, thereby driving the aeration grid 130 to move axially along the vertical pole 110, thereby adjusting the distance between the aeration grid 130 and the water surface.
[0106] In one possible implementation, the distance between the aeration grid 130 and the water surface is determined based on at least one of the following:
[0107] The power of the blower 140;
[0108] Aeration pipe pressure.
[0109] In some embodiments, the moving member 122 includes a collar mounted on the upright pole 110;
[0110] The second locking component includes a bolt penetrating through the side wall of the collar.
[0111] In a possible implementation, the moving component 122 includes a collar sleeved on the vertical pole 110. The first connecting rod 121 between the vertical poles 110 can be connected to the collar by welding or other methods, so that the moving component 122 can move axially along the vertical pole 110.
[0112] The second locking component includes a bolt penetrating the side wall of the collar. When the bolt is tightened, the top of the bolt abuts against the outer wall of the vertical rod 110 to prevent the collar from moving.
[0113] In some embodiments, a sealing belt (not shown in the figure) is provided along the axial direction of the aeration hose 131 on the bottom surface of the aeration hose 131 facing the bottom of the water body for sealing the gap on the bottom surface. The width of the sealing belt in the circumferential direction of the aeration hose 131 is 7.5% to 15% of the circumference of the aeration hose 131 .
[0114] Since bubbles generated when air is discharged from the bottom of the aeration hose 131 will rise along the tube wall of the aeration hose 131, they will merge with bubbles generated at other positions of the tube wall during the rising process, thereby reducing the contact area between the bubbles and the water body, thereby reducing the oxygenation effect. Therefore, the bottom of the aeration hose 131 facing the bottom of the water body can be sealed with a sealing tape so that no bubbles are generated at the bottom of the aeration hose 131.
[0115] In a possible implementation, the sealing tape may be made of at least one of the following materials: polyethylene, polyvinyl chloride, ABS and polypropylene.
[0116] In a possible implementation, the sealing tape may be bonded to the bottom of the aeration hose 131 by bonding. For example, latex may be used to bond the sealing tape.
[0117] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form other embodiments of the present invention that may not be explicitly described. Therefore, the above embodiments only express several implementations of the present invention and do not limit the scope of protection of the patent of the present invention.
