Description

Technical Field

[0001] The present invention relates to the technical field of gas-liquid dissolution, and particularly to a gas-liquid dissolution device and a dissolution method. Background Art

[0002] Gas-liquid dissolution devices mainly utilize specific structures and methods to efficiently dissolve gases (such as oxygen, carbon dioxide, etc.) in liquids (such as water, solutions, etc.), thereby increasing the dissolved oxygen concentration of the liquid or achieving other specific chemical reactions.

[0003] The Chinese patent application document with the publication number CN117919992A discloses a dissolution and mixing method and device for negative oxygen ion gas and liquid; in this invention, by setting a negative oxygen ion gas generator, a booster air pump, exhaust pipe components, a stator assembly and a rotor assembly, after the negative oxygen ion gas generator generates negative oxygen ion gas, the booster air pump pressurizes the negative oxygen ion gas, so that the negative oxygen ion gas enters the box through the exhaust pipe components and forms multiple bubbles inside the box, increasing the contact area between the negative oxygen ion gas and the mixed liquid. At this time, the motor drives the rotor assembly to rotate, and the rotor assembly rotates and impacts the bubbles inside the box. The small bubbles inside the box rotate with the liquid and contact the fixed rod and the moving rod, and the fixed rod and the moving rod break the bubbles, reducing the bubble volume and further increasing the contact area between the bubbles and the liquid, so that the negative oxygen ion gas is fully and quickly dissolved in the liquid.

[0004] In the actual implementation process of the above technical solution, since the exhaust pipe components are arranged at the bottom of the box, there are more bubbles at the bottom of the box. The liquid at the bottom of the box will be the first to mix and dissolve with the bubbles, while the mixing and dissolution degree of the liquid near the liquid surface with the bubbles is relatively low. In addition, during the process of the bubbles moving upward from the bottom of the box, due to the relatively fast rising speed of the bubbles and the fact that the bubbles may merge with other bubbles to form large bubbles during the rising process, the bubbles cannot be well dissolved with the liquid, resulting in the problem of low dissolution rate.

[0005] Therefore, there is a need in the art for a gas-liquid dissolution device and a dissolution method to solve the above problems. Summary of the Invention

[0006] The present invention provides a gas-liquid dissolution device and a dissolution method, aiming to solve the problems that the dissolution degrees of the liquid at the bottom and the top of the gas-liquid dissolution device in the related art with the gas are different and the overall dissolution rate is relatively low.

[0007] On the one hand, the present invention provides a gas-liquid dissolution device, which includes a tank body, a booster air pump and a stirring assembly. An exhaust pipe communicated with the booster air pump is arranged at the bottom of the tank body, and a cover body is arranged at the top. The stirring assembly is installed at the bottom of the tank body. A partition member is arranged in the tank body, and the partition member divides the interior of the tank body into an upper space and a lower space. A driving assembly one for driving the partition member to move up and down is arranged on the cover body. A communicating pipe for communicating the upper space and the lower space is arranged on the tank body, and a valve assembly is arranged in the communicating pipe. A spray cylinder and a water delivery assembly are connected below the partition member, and spray holes are formed in the spray cylinder;

[0008] When the air pressure in the lower space reaches a preset value, the valve assembly is controlled to open, and the driving assembly one drives the partition member to move downward. The air pressure squeezes the liquid near the bottom in the lower space into the upper space through the communicating pipe. During the process of the partition member moving downward, the water delivery assembly transports the liquid at the top in the lower space into the spray cylinder for spraying.

[0009] Since there are more bubbles at the bottom of the tank body, the liquid at the bottom will be the first to mix and dissolve with the gas. Squeezing the liquid with better dissolution effect at the bottom into the upper space can make the remaining liquid in the lower space closer to the bubbles at the bottom, improving the gas-liquid dissolution efficiency; moreover, by transporting the liquid at the top in the lower space into the spray cylinder for spraying, the liquid at the top is sprayed into the gas above the liquid surface, improving the dissolution efficiency of the liquid at the top and the gas, so as to realize that the liquids at different positions in the tank body can be better dissolved with the gas, and improving the overall dissolution rate.

[0010] Preferably, a blocking member is rotatably connected to the partition member, and air spray holes are respectively formed in the partition member and the blocking member. A driving assembly two for driving the blocking member to rotate is arranged on the partition member. When the partition member moves downward to a preset position, the valve assembly closes, and the driving assembly two drives the blocking member to rotate. When the air spray holes on the blocking member and the partition member are communicated, the gas in the lower space enters the upper space through the air spray holes.

[0011] By spraying the gas in the lower space into the upper space, the liquid in the upper space is mixed and dissolved with the gas again, which is beneficial to the liquid and gas in the whole tank body gradually reaching the state of dissolution saturation.

[0012] Preferably, a through hole one and a through hole two are formed in the tank body. A U-shaped plate is slidably arranged vertically in the communicating pipe, and a through hole three and a through hole four are formed in the U-shaped plate. Magnets with opposite magnetic poles are arranged between the top of the communicating pipe and the top of the U-shaped plate. When the air pressure in the lower space reaches a preset value, the valve assembly drives the U-shaped plate to move upward, and the magnets attract each other, so that the through hole one is communicated with the through hole three, and the through hole two and the through hole four are communicated. When the partition member moves downward to a preset position, the valve assembly drives the U-shaped plate to move downward to block the through hole one and the through hole two.

[0013] Preferably, the valve assembly includes a movable rod, a first lever and a second lever. A push plate is fixedly connected to the bottom of the movable rod. The movable rod is elastically connected to the partition member in the vertical direction. The first lever and the second lever are respectively fixedly connected to the U-shaped plate. The tank body is provided with sliding grooves for the first lever and the second lever to move vertically respectively. The first lever and the second lever penetrate through the sliding grooves and extend into the tank body. When the air pressure in the lower space reaches a preset value, the air pressure pushes the push plate to drive the movable rod to move upward. The movable rod pushes the first lever to drive the U-shaped plate to move upward. When the partition member moves downward to a preset position, the partition member presses the second lever to drive the U-shaped plate to move downward.

[0014] Through the cooperation between the movable rod and the first lever, and the cooperation between the partition member and the second lever, the communication and disconnection between the connecting pipe and the inside of the tank body are realized. The structure is simple and ingenious. There is no need to set a separate control valve, which reduces the cost and improves the structural compactness of the device at the same time.

[0015] Preferably, the water delivery assembly includes a first motor, a mounting rod and a spiral blade. The first motor is fixedly installed on the cover body. The mounting rod is connected to the first motor through a telescopic rod. The spiral blade is fixedly connected to the mounting rod, and the spiral blade is located inside the injection cylinder. A connecting assembly is arranged between the mounting rod and the partition member. When the partition member moves vertically, the mounting rod is driven to move synchronously through the connecting assembly.

[0016] Preferably, a plurality of liquid storage cavities are arranged at intervals on the outer periphery of the injection cylinder. The liquid storage cavities are respectively communicated with the inside of the injection cylinder through a first communication port. The injection holes are communicated with the liquid storage cavities. A baffle is rotatably connected inside the injection cylinder and is located below the first communication port. The baffle is connected to the mounting rod. A second communication port is opened on the baffle. When the mounting rod drives the baffle to rotate and the second communication port corresponds to the first communication port up and down, the corresponding liquid storage cavity is communicated with the inside of the injection cylinder.

[0017] By arranging the baffle, when the second communication port on the baffle faces the corresponding first communication port of the liquid storage cavity, the liquid in the injection cylinder can enter the injection cavity and spray out. When the baffle blocks the first communication port, since the spiral blade continuously rotates to convey the liquid, the pressure in the injection cylinder will increase. Therefore, when the second communication port and the first communication port are communicated, the liquid can be sprayed out, which is beneficial to the mixing and dissolution of the liquid and the gas.

[0018] Preferably, the connecting assembly includes a connecting disk and an inserting rod. The connecting disk is sleeved on the outer periphery of the mounting rod, and an annular groove is opened on the inner periphery of the connecting disk. A convex edge adapted to the annular groove extends on the outer periphery of the mounting rod. The inserting rod is fixedly connected to the connecting disk in the vertical direction. A sleeve rod is fixedly connected to the top of the partition member, and the inserting rod is inserted into the sleeve rod.

[0019] Preferably, a top push rod extending vertically is provided at the center of the bottom of the tank body. The second driving assembly includes a first clamping block and a second clamping block. The first clamping blocks are distributed at intervals along the outer periphery of the mounting rod and fixedly connected to the mounting rod. The second clamping blocks are distributed at intervals along the outer periphery of the mounting rod and fixedly connected to the bottom of the blocking member. The bottom of the blocking member is elastically matched with the mounting rod through an elastic member. Before the partition member moves to the preset position, the second clamping block is located above the first clamping block. When the partition member moves to the preset position, the mounting rod presses against the top push rod, and the second clamping block enters between two adjacent first clamping blocks. When the mounting rod rotates, the blocking member is driven to rotate through the cooperation of the first clamping block and the second clamping block.

[0020] Before the partition member moves to the preset position, the second clamping block is located above the first clamping block. During the process of the mounting rod driving the spiral blade to rotate, the blocking member will not rotate following the mounting rod, and the air injection holes on the blocking member and the partition member will not communicate, ensuring that the liquid in the lower space can be squeezed into the upper space. After the mounting rod contacts the top push rod, as the partition member continues to move downward, the second clamping block will enter between the first clamping blocks. Driven by the first clamping block, the second clamping block drives the blocking member to move, so that the air injection holes on the blocking member can communicate with the air injection holes on the partition member, realizing the injection of gas in the lower space into the upper space.

[0021] Preferably, the stirring assembly includes a second motor and an L-shaped stirring rod. The second motor is fixedly connected to the bottom of the tank body, and the output shaft of the second motor penetrates into the interior of the tank body. The L-shaped stirring rods are evenly distributed at intervals along the circumference of the output shaft and fixedly connected to the output shaft.

[0022] On the other hand, the present invention also provides a gas-liquid dissolution method. The gas-liquid dissolution method uses the gas-liquid dissolution device described in any one of the above preferred technical solutions. The gas-liquid dissolution method includes the following steps:

[0023] Add liquid into the tank body, cover and seal the cover body, control the booster air pump to introduce gas into the exhaust pipe, and control the stirring assembly to stir;

[0024] As the exhaust pipe continuously discharges gas into the tank body, the air pressure in the lower space gradually increases. When the air pressure in the lower space reaches the preset value, control the valve assembly to open, and the first driving assembly drives the partition member to move downward. The air pressure squeezes the liquid near the bottom in the lower space from the communicating pipe into the upper space, reducing the liquid in the lower space, so that the liquid in the lower space can fully contact and dissolve with the gas;

[0025] During the process of the partition member moving downward, control the water delivery assembly to convey the liquid at the top in the lower space to the injection cylinder for injection, so that the injected liquid can fully contact and dissolve with the gas above the liquid surface.

[0026] The beneficial effects of the gas-liquid dissolution method of the present invention are the same as those of the above gas-liquid dissolution device, and will not be elaborated here.

[0027] The beneficial effects of the present invention are as follows: By squeezing the liquid with better dissolution effect at the bottom in the lower space to the upper space, the liquid remaining in the lower space can be closer to the bubbles at the bottom, improving the gas-liquid dissolution efficiency. Moreover, through the water delivery component, the liquid at the top in the lower space is transported into the spraying cylinder for spraying, so that the liquid at the top is sprayed into the gas above the liquid surface, improving the dissolution efficiency of the liquid at the top and the gas, thereby realizing that the liquids at different positions in the tank can dissolve better with the gas and improving the overall dissolution rate.

[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as a limitation to the present invention.

[0040] As Figures 1 to 9 shown, a gas-liquid dissolution device of the present invention includes a tank body 1, a booster air pump (not shown in the figure), and a stirring assembly. An exhaust pipe 11 communicated with the booster air pump is arranged at the bottom of the tank body 1, and a cover body 12 is arranged at the top. The exhaust pipe 11 is coiled around the bottom of the tank body 1, and a plurality of exhaust holes are evenly spaced at the top of the exhaust pipe 11. A liquid inlet 13 is arranged at a position close to the bottom on the side wall of the tank body 1. The stirring assembly includes a second motor 2 and an L-shaped stirring rod 21. The second motor 2 is fixedly connected to the bottom of the tank body 1, and the output shaft of the second motor 2 penetrates into the tank body 1. The L-shaped stirring rods 21 are evenly distributed circumferentially along the output shaft and are fixedly connected to the output shaft. During gas-liquid dissolution, the L-shaped stirring rods 21 stir the liquid and gas to accelerate gas-liquid dissolution.

[0041] As Figures 2 to 6 shown, a partition member 3 is arranged in the tank body 1. The partition member 3 includes an integrally formed partition cylinder 31 and a partition ring 32. The outer periphery of the partition ring 32 is attached to the inner wall of the tank body 1. The partition member 3 divides the interior of the tank body 1 into an upper space and a lower space. Two connecting pipes 4 communicating the upper space and the lower space are symmetrically arranged on the left and right sides of the tank body 1. A valve assembly is arranged in the connecting pipe 4. A spraying cylinder 5 and a water delivery assembly are connected below the partition member 3. The spraying cylinder 5 is fixedly connected to the installation ring through a connecting rod 51. Spraying holes 52 are arranged on the spraying cylinder 5. A first driving assembly for driving the partition member 3 to move up and down is arranged on the cover body 12. As an example, the first driving assembly is a hydraulic telescopic cylinder 14. The hydraulic telescopic cylinder 14 is fixedly installed on the cover body 12, and its output end penetrates through the cover body 12 and is fixedly connected to the partition member 3.

[0042] When gas is dissolved in liquid, gas is continuously introduced into the tank body 1 through a pressurizing air pump. The air pressure in the lower space of the partition member 3 will gradually rise. When the air pressure in the lower space reaches a preset value, the control valve assembly is opened, and the first driving assembly drives the partition member 3 to move downward. The air pressure squeezes the liquid near the bottom in the lower space from the connecting pipe 4 into the upper space. Since there are more bubbles at the bottom of the tank body 1, the liquid at the bottom will first mix and dissolve with the gas. The liquid with better dissolution effect at the bottom is squeezed into the upper space, which can make the remaining liquid in the lower space closer to the bubbles at the bottom, improving the gas-liquid dissolution efficiency. Moreover, during the downward movement of the partition member 3, the water delivery assembly is controlled to convey the liquid at the top in the lower space to the injection cylinder 5 for injection, so that the liquid at the top is sprayed into the gas above the liquid surface, improving the dissolution efficiency of the liquid at the top and the gas, thereby enabling the liquid at different positions in the tank body 1 to dissolve better with the gas and improving the overall dissolution rate.

[0043] A blocking member 6 is rotatably connected to the partition member 3. The blocking member 6 is in the shape of a cylinder with an open bottom and fits the inner wall of the partition cylinder 31. Spray holes 61 are respectively formed in the partition cylinder 31 and the blocking member 6. A second driving assembly for driving the blocking member 6 to rotate is arranged on the partition member 3. When the partition member 3 moves downward to a preset position, the valve assembly is closed, and the second driving assembly drives the blocking member 6 to rotate. When the spray holes 61 on the blocking member 6 and the partition member 3 are communicated, the gas in the lower space enters the upper space through the spray holes 61.

[0044] When the partition member 3 moves downward to a preset position, most of the liquid in the lower space has been squeezed into the upper space, and the remaining liquid volume in the lower space is small, the liquid level is low, and the liquid can already be quickly mixed and dissolved with the bubbles at the bottom. At this time, the valve assembly is closed. When the spray holes 61 on the blocking member 6 and the partition member 3 are communicated, the gas in the lower space enters the upper space through the spray holes 61, enabling the liquid in the upper space to be mixed and dissolved with the gas again, so that the liquid and gas in the entire tank body 1 gradually reach a dissolution saturation state.

[0045] Such as Figure 2 and Figure 3As shown in the figure, through holes 15 and 16 corresponding to the connecting pipe 4 are respectively formed on the left and right sides of the tank body 1. The through hole 15 is located at a position near the bottom of the side wall of the tank body 1, and the through hole 16 is located above the through hole 15. A U-shaped plate 41 is slidably arranged vertically in the connecting pipe 4. Through holes 42 and 43 are formed on the U-shaped plate 41. Magnets with opposite magnetic poles are arranged between the top of the connecting pipe 4 and the top of the U-shaped plate 41 (not shown in the figure). When the air pressure in the lower space reaches the preset value, the valve assembly drives the U-shaped plate 41 to move upward, the magnets attract each other, the through hole 15 is communicated with the through hole 42, the through hole 16 and the through hole 43 are communicated, and the liquid in the lower space enters the connecting pipe 4 under the action of air pressure through the through hole 15 and the through hole 42, and enters the upper space through the through hole 43 and the through hole 16. When the separating member 3 moves downward to the preset position, the valve assembly drives the U-shaped plate 41 to move downward to block the through holes 15 and 16.

[0046] As Figures 2 to 5 shown, the valve assembly includes a movable rod 33, a first lever 44 and a second lever 45. An upwardly recessed installation cavity 34 is formed on the separating ring 32. The movable rod 33 is located in the installation cavity 34 and penetrates through the separating ring 32. A push plate 36 that fits against the inner wall of the installation cavity 34 is fixedly connected to the bottom of the movable rod 33, and a top plate 37 is fixedly connected to the top. A spring is connected between the push plate 36 and the top of the installation cavity 34. The first lever 44 and the second lever 45 are respectively fixedly connected to the U-shaped plate 41. The tank body 1 is provided with sliding grooves for the first lever 44 and the second lever 45 to move vertically. The first lever 44 and the second lever 45 penetrate through the sliding grooves and extend into the tank body 1.

[0047] When the air pressure in the lower space reaches the preset value, the air pressure pushes the push plate 36 to drive the movable rod 33 to move upward. The movable rod 33 pushes the first lever 44 through the top plate 37 to drive the U-shaped plate 41 to move upward, so that the connecting pipe 4 is communicated with the inside of the tank body 1. When the separating member 3 moves downward to the preset position, the separating ring 32 of the separating member 3 presses down the second lever 45 to drive the U-shaped plate 41 to move downward, blocking the communication between the connecting pipe 4 and the inside of the tank body 1.

[0048] As Figures 4 to 6 、 Figure 9As shown in the figure, the water delivery component includes a first motor 7, a mounting rod 71, and a spiral blade 72. The first motor 7 is fixedly installed on the cover body 12. The mounting rod 71 is connected to the first motor 7 through a telescopic rod. The spiral blade 72 is fixedly connected to the mounting rod 71, and the spiral blade 72 is located inside the injection cylinder 5. A connection component is arranged between the mounting rod 71 and the partition member 3. The connection component includes a connection disk 73 and an insertion rod 74. The connection disk 73 is sleeved on the outer periphery of the mounting rod 71, and an annular groove is formed in the inner periphery of the connection disk 73. A convex edge adapted to the annular groove extends from the outer periphery of the mounting rod 71. The insertion rod 74 is fixedly connected to the connection disk 73 along the vertical direction. A sleeve rod 35 is fixedly connected to the top of the partition member 3, and the insertion rod 74 is inserted into the sleeve rod 35.

[0049] Four liquid storage cavities 53 are arranged at intervals on the outer periphery of the injection cylinder 5. The injection holes 52 are communicated with the liquid storage cavities 53. The liquid storage cavities 53 are respectively communicated with the inside of the injection cylinder 5 through a first communication port 54. A baffle 8 located below the first communication port 54 is rotatably connected inside the injection cylinder 5. The baffle 8 is connected to the mounting rod 71, and a second communication port 81 is formed on the baffle 8. When the first motor 7 drives the mounting rod 71 to rotate, the spiral blade 72 on the mounting rod 71 conveys the liquid near the top to the inside of the injection cylinder 5. During the rotation of the mounting rod 71, the baffle 8 is driven to rotate. When the second communication port 81 and the first communication port 54 are vertically corresponding, the corresponding liquid storage cavity 53 is communicated with the inside of the injection cylinder 5. The liquid inside the injection cylinder 5 enters the liquid storage cavity 53 and is sprayed above the liquid surface from the injection holes 52.

[0050] As Figure 4 、 Figures 6 to 9 shown in the figure, a top push rod 22 extending vertically is arranged at the center of the bottom of the tank body 1. The top push rod 22 is fixedly connected to the output shaft of the second motor 2. The second driving component includes a first clamping block 75 and a second clamping block 62. The first clamping blocks 75 are distributed at intervals along the outer periphery of the mounting rod 71 and are fixedly connected to the mounting rod 71. The second clamping blocks 62 are distributed at intervals along the outer periphery of the mounting rod 71 and are fixedly connected to the bottom of the blocking member 6. The bottom of the blocking member 6 is elastically matched with the mounting rod 71 through a spring. Before the partition member 3 moves to the preset position, the second clamping block 62 is located above the first clamping block 75. When the partition member 3 moves to the preset position, the mounting rod 71 presses against the top push rod 22 and cannot continue to move downward. During the process of the partition member 3 continuing to move downward, the blocking member 6 squeezes the spring, and the second clamping block 62 on the blocking member 6 enters between two adjacent first clamping blocks 75. As the mounting rod 71 rotates, the first clamping block 75 and the second clamping block 62 cooperate to drive the blocking member 6 to rotate, so as to realize the communication between the air injection holes 61 on the blocking member 6 and the air injection holes 61 on the partition member 3, and spray the gas in the lower space to the upper space.

[0051] A gas-liquid dissolution method uses the gas-liquid dissolution device in the above embodiment. The gas-liquid dissolution method includes the following steps:

[0052] Add liquid into the tank body 1, cover and tightly seal the cover body 12, control the booster air pump to introduce gas into the exhaust pipe 11, and control the stirring assembly to stir;

[0053] As the exhaust pipe 11 continuously discharges gas into the tank body 1, the air pressure in the lower space gradually increases. When the air pressure in the lower space reaches the preset value, the air pressure pushes the push plate 36 to drive the movable rod 33 to move upward. The movable rod 33 drives the first shift lever 44 through the top plate 37 to drive the C-shaped plate 41 to move upward, so that the connecting pipe 4 is communicated with the inside of the tank body 1. Control the hydraulic telescopic cylinder 14 to drive the partition member 3 to move downward. The air pressure squeezes the liquid near the bottom in the lower space from the connecting pipe 4 into the upper space, reducing the liquid in the lower space, so that the liquid in the lower space can fully contact and dissolve with the gas;

[0054] During the process of the partition member 3 moving downward, control the first motor 7 to drive the mounting rod 71 to rotate. The spiral blade 72 on the mounting rod 71 transports the liquid near the top to the injection cylinder 5. During the rotation of the mounting rod 71, the baffle 8 is driven to rotate. When the second communication port 81 and the first communication port 54 are vertically corresponding, the corresponding liquid storage cavity 53 is communicated with the inside of the injection cylinder 5. The liquid in the injection cylinder 5 enters the liquid storage cavity 53 and is sprayed above the liquid surface through the spray holes 52, so that the sprayed liquid can fully contact and dissolve with the gas above the liquid surface;

[0055] When the partition member 3 continues to move downward until the mounting rod 71 contacts the top push rod 22, the mounting rod 71 cannot continue to move downward. The partition member 3 drives the blocking member 6 to continue to move downward. The second clamping block 62 on the blocking member 6 enters between two adjacent first clamping blocks 75. At the same time, the partition member 3 presses down the second shift lever 45 to drive the C-shaped plate 41 to move downward, blocking the communication between the connecting pipe 4 and the inside of the tank body 1. As the mounting rod 71 rotates, the first clamping block 75 and the second clamping block 62 cooperate to drive the blocking member 6 to rotate. When the air spray holes 61 on the blocking member 6 are opposite to the air spray holes 61 on the partition member 3, the gas in the lower space is sprayed into the liquid in the upper space.
