Description

Technical Field

[0001] The present invention belongs to the technical field of water source treatment, and in particular, relates to a pulse vertical flow aeration mixing device for improving and repairing water quality. Background Art

[0002] Deepwater lakes and reservoirs have the so-called "thermal stratification effect", which mainly refers to abnormal water quality such as dissolved oxygen, pH, iron and manganese, ammonia nitrogen, and chlorophyll a caused by the physical stable stratification of lakes and reservoirs. The physical stable stratification of lakes and reservoirs is seasonal. The surface water temperature rises rapidly due to the high temperature in summer and autumn, while the deeper water is less affected by the air temperature, resulting in a vertical difference in water temperature, which in turn causes a difference in water density. Water convection stops and a stable stratified structure is formed. This stratified structure is caused by rising air temperatures and is therefore called "thermal stratification." The thermal stratification of deepwater lakes and reservoirs hinders the vertical exchange of matter and energy in the water body, which is prominently manifested in the obvious difference in vertical dissolved oxygen content: the surface water environment is in an oxygen-rich oxidation state, while the bottom water environment is in an oxygen-deficient anaerobic reduction state. This induces the transformation and release of pollutants in the bottom sediments into the overlying water body, forming endogenous pollution and having an adverse effect on the water quality of the lakes and reservoirs.

[0003] Announcement No. CN106745869B discloses a pulse vertical flow aeration mixing device for destroying / disturbing seasonal structural stratification of water bodies in deep-water lakes and reservoirs (water depth greater than 10 meters, the same below) to improve and repair water quality; it includes a float, a perforated water inlet riser, a vertical flow riser, a pulsating aeration oxygenator, and a fixed anchor; a float is arranged at the upper end of the perforated water inlet riser, and the lower end of the perforated water inlet riser is connected to the pulsating aeration oxygenator through the vertical flow riser, and a fixed anchor is arranged at the bottom of the pulsating aeration oxygenator; the pulsating aeration oxygenator includes a water inlet tank, a pulsating generating tank, and an air inlet tank which are arranged in sequence from top to bottom; the water inlet tank and the air inlet tank can be connected to the pulsating generating tank, and the pulsating generating tank is provided with a gas-water injection seam; the present invention utilizes the natural potential energy of the surface water body to introduce the surface water body into the bottom of the lake or reservoir, fully utilizes the power resources, and reduces energy consumption.

[0004] The existing device can only perform pulsation operation at a certain position when performing pulsation aeration and mixing on lake water. Performing aeration and mixing at one place for a long time can easily lead to uneven mixing of the overall lake water. Staying at one place for a long time can easily lead to excessive oxygen enrichment and waste of resources.

[0005] In order to solve the above problems, the present application proposes a pulse vertical flow aeration mixing device for improving and repairing water quality. Summary of the invention

[0006] In view of the problems in the related art, the present invention proposes a pulse vertical flow aeration mixing device for improving and repairing water quality to overcome the above-mentioned technical problems existing in the existing related art.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A pulse vertical flow aeration and mixing device for improving and repairing water quality comprises a floating ring, a plurality of support rods are fixedly installed on the top of the floating ring, a top plate is fixedly installed on the top ends of the plurality of support rods, and an air compressor is fixedly installed on the top of the top plate;

[0009] A water guide plate is arranged on the inner side of the floating ring, a water guide pipe is fixedly installed at the bottom of the water guide plate, a pulsation generating chamber is installed at the bottom end of the water guide pipe, an air guide pipe is connected to the air compressor, the air guide pipe penetrates the water guide pipe and extends into the pulsation generating chamber;

[0010] The anchor ball is set below the pulsation chamber and connected by a traction rope, and the length is adjustable during installation;

[0011] The pulsation mechanism comprises a stamping plate, which is slidably mounted on the inner wall of the pulsation chamber and fits the inner wall of the pulsation chamber. A mounting box is mounted on one side of the pulsation chamber, the mounting box is connected to the pulsation chamber, and a plurality of drainage cylinders are mounted on the outer side of the mounting box.

[0012] The water injection mechanism comprises a water injection tank, which is fixedly mounted on the top inner wall of the pulsation chamber, the water injection tank is interconnected with the water guide pipe, and the bottom end of the air guide pipe passes through the water injection tank and is located in the pulsation chamber.

[0013] Preferably, the pulsation generating mechanism also includes six push rods, which are fixedly mounted on one side of the stamping plate, and are slidably connected to one side of the pulsation generating chamber. A return spring is sleeved on the push rod, and the return spring is located between the stamping plate and an inner wall of one side of the pulsation generating chamber.

[0014] Through the sliding setting of the stamping plate and the pulsation generating chamber, it can be pushed and moved under the action of the air guide tube, and the push rod and the pulsation generating chamber are slidingly connected, so as to limit the position. At the same time, kinetic energy compression is carried out under the action of the return spring, which is convenient for the rebound of the later gas intake, thereby forming a pulsation impact, which is convenient for the gas and the upper water source and deep water to be fully mixed.

[0015] Preferably, a push rod is slidably connected to the stamping plate, a plug plate is fixedly installed on one end of the push rod, the plug plate cooperates with the installation box, and four symmetrically arranged arc-shaped spring pieces are fixedly installed on the other end of the push rod, the four arc-shaped spring pieces are fixedly connected to the inner wall of the pulsation generating chamber, and a stopper is fixedly installed on the push rod, and the stopper cooperates with the arc-shaped spring piece.

[0016] Through the sliding connection between the stamping plate and the push rod, the stamping plate will not drive the push rod when it slides on the push rod. When the stamping plate moves to the position of the arc-shaped spring piece, the arc-shaped spring piece is pushed to deform the arc-shaped spring piece. When the arc-shaped spring piece is deformed to the reverse direction, the arc-shaped spring piece drives the push rod to move instantly, so that the push rod drives the plug plate to move out of the installation box position, and then the gas and water in the pulsation chamber are discharged through the installation box and the drain cylinder. After one side of the stamping plate is depressurized, the stamping plate is pushed to move in the opposite direction under the action of the reset spring. When the stamping plate moves to the position of the stop block, the stop block drives the push rod and the plug plate to reset, and then drives the plug plate to re-close the installation box.

[0017] Preferably, one side of the installation box is rotatably connected to a propeller blade, and the propeller blade cooperates with a plurality of drainage cylinders.

[0018] The water and gas in the installation box are discharged through the drainage tube. At the same time, the impact force of the discharged water and gas acts on the propeller blades, thereby driving the propeller blades to rotate. At the same time, the discharged water and gas are stirred under the action of the rotating propeller blades. The flushed water and gas pass through the deep water outside the pulsation generating chamber, thereby driving the pulsation generating chamber to move, so that the device can perform water quality mixing repair operations on different deep water areas.

[0019] Preferably, the water injection mechanism further comprises two mounting pipes, the two mounting pipes are fixedly mounted on the bottom inner wall of the water injection bin, and the two mounting pipes are interconnected with the pulsation generating bin, and the water injection pipes are fixedly mounted on the inner wall of the mounting pipes.

[0020] The water source in the water injection bin is discharged through the water injection pipe, and the arrangement of the installation pipe can facilitate the installation of the water injection pipe.

[0021] Preferably, two baffles are fixedly mounted on one side of the stamping plate, and guide holes are formed on the baffles, and the guide holes cooperate with corresponding mounting tubes.

[0022] By setting the baffle, the installation pipe and the water injection pipe can be easily closed, thereby preventing gas from flowing back.

[0023] Preferably, a same push plate is fixedly mounted on one side of the six push rods, an L-shaped pressing plate is fixedly mounted on the push plate, an L-shaped inclined groove is provided on the L-shaped pressing plate, and the L-shaped inclined groove is movably connected to the water pipe.

[0024] The moving top rod drives the push plate to move, and the push plate drives the L-shaped pressure plate to move. The L-shaped pressure plate is movably connected to the water pipe through the L-shaped inclined groove, thereby driving the water pipe to bend. When the water pipe bends, it can pull the water guide plate downward, so that the water guide plate is immersed under the water surface, thereby introducing the water source on the water surface through the water pipe.

[0025] Preferably, an isolation net is installed at the bottom of the floating ring, and the isolation net cooperates with the water guide plate.

[0026] By setting up the isolation net, it is convenient to filter the water source flowing into the water guide plate to prevent the water guide pipe from being blocked.

[0027] Preferably, both sides of the ends of the water injection pipe and the drainage cylinder are provided with wedge-shaped surfaces, and the ends of the water injection pipe and the drainage cylinder are provided with openings.

[0028] By setting the wedge-shaped surfaces at the ends of the water injection pipe and the drainage tube, when the gas or liquid outside the water injection pipe and the drainage tube flows in the opposite direction, the opening position can be closed under the action of the wedge-shaped surfaces, thereby achieving a one-way flow effect and preventing the gas and liquid from flowing back.

[0029] In summary, the technical effects and advantages of the present invention are as follows:

[0030] Through the sliding connection between the stamping plate and the pulsation generating chamber, and the action of the air compressor and the air duct on the pulsation generating chamber, and under the action of the reset spring, the air can be compressed in the pulsation generating chamber, and when the plug plate is opened, the stamping plate can be pushed by the reset spring to reset it, so that the pulse discharge mixture is carried out through the installation box and the drainage tube.

[0031] By setting the anchor ball, the device can be fixed in a certain area in the water, thereby pulse mixing in the area. At the same time, by setting the propeller blades, the discharged gas and the water source can be stirred to increase the degree of mixing with the deep water.

[0032] Through the cooperation between the guide hole on the baffle and the installation pipe, and under the action of the water injection pipe, water can be automatically injected into the pulsation generating chamber, so that the water on the water surface and the deep water can be mixed.

A plurality of drainage cylinders 69 are mounted on the outer side of the mounting box 68.

[0049] The water injection mechanism 7 includes a water injection tank 71, which is fixedly mounted on the top inner wall of the pulsation chamber 5. The water injection tank 71 is interconnected with the water guide pipe 4. The bottom end of the air guide pipe 10 passes through the water injection tank 71 and is located in the pulsation chamber 5.

[0050] Reference Figure 4 and Figure 5 The pulsation generating mechanism 6 also includes six push rods 62, which are fixedly mounted on one side of the stamping plate 61. The push rods 62 are slidably connected to one side of the pulsation generating chamber 5. A reset spring 64 is sleeved on the push rod 62. The reset spring 64 is located between the stamping plate 61 and the inner wall of one side of the pulsation generating chamber 5. Through the sliding setting of the stamping plate 61 and the pulsation generating chamber 5, it can be pushed and moved under the action of the air guide tube 10, and the push rod 62 is slidably connected to the pulsation generating chamber 5, so that it can be limited. At the same time, kinetic energy is compressed under the action of the reset spring 64, which is convenient for the rebound of the incoming gas in the later stage, thereby forming a pulsation shock, which is convenient for the gas and the upper water source and the deep water to be fully mixed.

[0051] Reference Figure 6 A push rod 65 is slidably connected to the stamping plate 61, and a plug plate 67 is fixedly installed at one end of the push rod 65. The plug plate 67 cooperates with the installation box 68, and four symmetrically arranged arc spring pieces 63 are fixedly installed at the other end of the push rod 65. The four arc spring pieces 63 are fixedly connected to the inner wall of the pulsation generating chamber 5. A stopper 66 is fixedly installed on the push rod 65, and the stopper 66 cooperates with the arc spring piece 63. Through the sliding connection between the stamping plate 61 and the push rod 65, the stamping plate 61 will not drive the push rod 65 when sliding on the push rod 65. When the stamping plate 61 moves to the position of the arc spring piece 63, the arc spring piece 63 is pushed The arc-shaped spring piece 63 is pushed, causing the arc-shaped spring piece 63 to deform. When the arc-shaped spring piece 63 is deformed to the reverse direction, the arc-shaped spring piece 63 drives the push rod 65 to move instantly, so that the push rod 65 drives the plug plate 67 to move out of the installation box 68 position, thereby causing the gas and water in the pulsation chamber 5 to be discharged through the installation box 68 and the drain tube 69. After the pressure on one side of the stamping plate 61 is relieved, the stamping plate 61 is pushed to move in the reverse direction under the action of the reset spring 64. When the stamping plate 61 moves to the position of the stop block 66, the stop block 66 drives the push rod 65 and the plug plate 67 to reset, thereby driving the plug plate 67 to re-close the installation box 68.

[0052] Reference Figure 4One side of the installation box 68 is rotatably connected to a propeller blade 12, and the propeller blade 12 cooperates with multiple drainage tubes 69. The water and gas in the installation box 68 are discharged through the drainage tube 69. At the same time, the impact force of the discharged water and gas acts on the propeller blade 12, thereby pushing the propeller blade 12 to rotate. At the same time, the discharged water and gas are stirred under the action of the rotating propeller blade 12. The flushed water and gas pass through the deep water outside the pulsation generating chamber 5, thereby pushing the pulsation generating chamber 5 to move, so that the device can perform water quality mixing repair operations on different deep water areas.

[0053] Reference Figure 8 The water injection mechanism 7 also includes two mounting pipes 72, which are fixedly mounted on the bottom inner wall of the water injection bin 71, and the two mounting pipes 72 are connected to the pulsation generating bin 5. A water injection pipe 73 is fixedly mounted on the inner wall of the mounting pipe 72. Two baffles 75 are fixedly mounted on one side of the stamping plate 61. The baffles 75 are provided with guide holes 76, and the guide holes 76 cooperate with the corresponding mounting pipes 72. Both sides of the ends of the water injection pipe 73 and the drainage cylinder 69 are wedge-shaped, and the ends of the water injection pipe 73 and the drainage cylinder 69 are provided with openings. The water in the water tank 71 is discharged through the water injection pipe 73. At the same time, the setting of the installation pipe 72 can facilitate the installation of the water injection pipe 73. The setting of the baffle 75 can facilitate the sealing of the installation pipe 72 and the water injection pipe 73, thereby preventing the backflow of gas. The wedge-shaped surface at the end of the water injection pipe 73 and the drain tube 69 can make the water injection pipe 73 and the gas or liquid outside the drain tube 69 flow in the opposite direction. The opening position can be closed under the action of the wedge-shaped surface, thereby achieving a one-way flow effect and preventing the backflow of gas and liquid.

[0054] Reference Figure 1 A same push plate 14 is fixedly installed on one side of the six push rods 62, and an L-shaped pressing plate 15 is fixedly installed on the push plate 14.

The moving push rod 62 drives the push plate 14 to move, and the push plate 14 drives the L-shaped pressing plate 15 to move. The L-shaped pressing plate 15 is movably connected with the water pipe 4 through the L-shaped inclined groove 16, so that the water pipe 4 can be bent. When the water pipe 4 is bent, the water guide plate 3 can be pulled downward, so that the water guide plate 3 is immersed below the water surface, so that the water source on the water surface is introduced through the water pipe 4.

Through the setting of the isolation net 11, it is convenient to filter the water source flowing into the water guide plate 3 to prevent the water guide pipe 4 from being blocked.

[0056] Working principle: When working, the device is placed in water and placed on the bottom of the water through the anchor ball 13, so that the floating ring 1 can be anchored, and gas is injected into the pulsation chamber 5 through the air compressor 9 and the air pipe 10. The gas entering the pulsation chamber 5 is squeezed to push the stamping plate 61 to move, and the stamping plate 61 drives the top rod 62 to move. The moving top rod 62 drives the push plate 14 to move, and the push plate 14 drives the L-shaped pressing plate 15 to move. The L-shaped pressing plate 15 is movably connected with the water pipe 4 through the L-shaped inclined groove 16, so that the water pipe 4 can be bent. When the water pipe 4 is bent, the water guide plate 3 can be pulled downward The water guide plate 3 is moved so that the water guide plate 3 is immersed under the water surface, so that the water source on the water surface is introduced through the water guide pipe 4 and injected into the water injection tank 71, and the water source in the water injection tank 71 is discharged through the water injection pipe 73. At the same time, the installation pipe 72 is set, and the baffle plate 75 is set, which can facilitate the sealing of the installation pipe 72 and the water injection pipe 73, so as to prevent the gas from flowing back. The wedge-shaped surface at the end of the water injection pipe 73 and the drainage tube 69 is set, so that when the gas or liquid outside the water injection pipe 73 and the drainage tube 69 flow in the opposite direction, the opening position can be closed under the action of the wedge-shaped surface, so as to achieve a one-way flow effect, and prevent the gas and liquid from flowing back. When the punching plate 61 moves to the position of the arc spring piece 63, the arc spring piece 63 is pushed to deform the arc spring piece 63. When the arc spring piece 63 deforms to the reverse direction, the arc spring piece 63 drives the push rod 65 to move instantly, so that the push rod 65 drives the plug plate 67 to move out of the installation box 68 position, thereby allowing the gas and water in the pulsation chamber 5 to be discharged through the installation box 68 and the drain cylinder 69. After one side of the punching plate 61 is depressurized, the punching plate 61 is pushed to move in the reverse direction under the action of the reset spring 64. When the punching plate 61 moves to the position of the stopper 66, the stopper 66 drives the The push rod 65 and the plug plate 67 are reset, thereby driving the plug plate 67 to re-close the installation box 68. At the same time, the impact force of the discharged water and gas acts on the propeller blades 12, thereby pushing the propeller blades 12 to rotate. At the same time, the discharged water and gas are stirred under the action of the rotating propeller blades 12. The flushed water and gas pass through the deep water outside the pulsation chamber 5, thereby pushing the pulsation chamber 5 to move, so that the device can perform water quality mixing and repair operations on unused deep water areas. Through the setting of the isolation net 11, it is convenient to filter the water source flowing into the water guide plate 3 to prevent blockage of the water pipe 4.
