Description

Technical Field

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

[0002] The gas-liquid dissolution device mainly utilizes 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] A Chinese patent application document with publication number CN117919992A discloses a method and device for dissolving and mixing negative oxygen ion gas and liquid. The invention comprises a negative oxygen ion gas generator, a booster air pump, an exhaust pipe, 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 and forms multiple bubbles inside the box, thereby increasing the contact area between the negative oxygen ion gas and the mixed liquid. At this time, the motor drives the rotor assembly to operate, and the rotor assembly rotates and hits the bubbles inside the box. The small bubbles inside the box rotate with the liquid and contact the fixed rod and the moving rod. The fixed rod and the moving rod break up the bubbles, reduce the volume of the bubbles, and further increase 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] During the actual implementation of the above technical solution, since the exhaust pipe is arranged at the bottom of the box, there are more bubbles at the bottom of the box, and the liquid at the bottom of the box will be mixed and dissolved with the bubbles first, while the degree of mixed dissolution of the liquid and bubbles close to the liquid surface is relatively low. In addition, in the process of bubbles moving upward from the bottom of the box, since the bubbles rise quickly and may merge with other bubbles to form large bubbles during the rising process, the bubbles cannot be well dissolved in the liquid, resulting in the problem of low dissolution rate.

[0005] Therefore, the art needs 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 in the related art that the dissolution degree of the bottom liquid and the top liquid with the gas in the gas-liquid dissolution device is different and the overall dissolution rate is 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 inside 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. 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.

[0008] 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 through the water delivery assembly, 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 liquid at different positions in the tank body can dissolve better with the gas, and improving the overall dissolution rate.

[0009] 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.

[0010] 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.

[0011] Preferably, a through hole one and a through hole two are formed in the tank body. A C-shaped plate is slidably arranged vertically in the communicating pipe. Through holes three and four are formed in the C-shaped plate. Magnets with opposite magnetic poles are arranged between the top of the communicating pipe and the top of the C-shaped plate. When the air pressure in the lower space reaches a preset value, the valve assembly drives the C-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 C-shaped plate to move downward to block the through hole one and the through hole two.

[0012] 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 the 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 the preset position, the partition member presses the second lever to drive the U-shaped plate to move downward.

[0013] 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.

[0014] 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 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.

[0015] 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.

[0016] By setting 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.

[0017] Preferably, the connecting assembly includes a connecting disc and a plug rod. The connecting disc is sleeved on the outer periphery of the mounting rod, and an annular groove is opened on the inner periphery of the connecting disc. A convex edge adapted to the annular groove extends on the outer periphery of the mounting rod. The plug rod is fixedly connected to the connecting disc in the vertical direction. A sleeve rod is fixedly connected to the top of the partition member, and the plug rod is inserted into the sleeve rod.

[0018] Preferably, a vertically extending push rod is provided at the bottom center of the tank body, and the driving component 2 includes a block 1 and a block 2. The block 1 is distributed at intervals along the outer periphery of the mounting rod and is fixedly connected to the mounting rod, and the block 2 is distributed at intervals along the outer periphery of the mounting rod and is 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 moves to the preset position, the block 2 is located above the block 1. When the partition moves to the preset position, the mounting rod is pressed against the push rod, and the block 2 enters between two adjacent blocks 1. When the mounting rod rotates, the blocking member is driven to rotate through the cooperation of the block 1 and the block 2.

[0019] Before the partition moves to the preset position, block two is located above block one. During the process of the installation rod driving the spiral blade to rotate, the blocking member will not rotate with the installation rod, and the jet holes on the blocking member and the partition will not be connected, ensuring that the liquid in the lower space can be squeezed into the upper space. After the installation rod contacts the push rod, as the partition continues to move downward, block two will enter between block one. Driven by block one, block two drives the blocking member to move, so that the jet holes on the blocking member can be connected with the jet holes on the partition, thereby realizing the gas in the lower space being ejected into the upper space.

[0020] Preferably, the stirring assembly includes motor 2 and an L-shaped stirring rod. Motor 2 is fixedly connected to the bottom of the tank body, and the output shaft of motor 2 passes through the interior of the tank body. The L-shaped stirring rod is evenly distributed at circumferential intervals along the output shaft and is fixedly connected to the output shaft.

[0021] On the other hand, the present invention further provides a gas-liquid dissolution method, the gas-liquid dissolution method using the gas-liquid dissolution device described in any one of the above preferred technical solutions, the gas-liquid dissolution method comprising the following steps: Add liquid into the tank, seal the cover tightly, control the booster pump to pass gas into the exhaust pipe, and control the stirring assembly to stir; As the exhaust pipe continuously discharges gas into the tank, the air pressure in the lower space gradually increases. When the air pressure in the lower space reaches a preset value, the control valve assembly opens, and the drive assembly drives the partition to move downward. The air pressure squeezes the liquid near the bottom of the lower space from the connecting pipe to 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. During the downward movement of the partition, the water delivery assembly is controlled to deliver the liquid at the top of the lower space to the injection tube for injection, so that the injected liquid can fully contact and dissolve with the gas above the liquid surface.

[0022] The gas-liquid dissolution method of the present invention has the same beneficial effects as the above-mentioned gas-liquid dissolution device, which will not be described in detail here.

[0023] The beneficial effects of the present invention are as follows: by squeezing the liquid with better dissolution effect at the bottom of the lower space into the upper space, the remaining liquid in the lower space can be brought closer to the bubbles at the bottom, thereby improving the gas-liquid dissolution efficiency; and the liquid at the top of the lower space is transported to the injection tube for injection through the water delivery component, so that the liquid at the top is sprayed into the gas above the liquid surface, thereby improving the dissolution efficiency of the top liquid and gas, thereby achieving that the liquid at different positions in the tank body can be better dissolved with the gas, thereby improving the overall dissolution rate.

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0035] 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 communicating with the booster air pump is provided at the bottom of the tank body 1, and a cover body 12 is provided at the top. The exhaust pipe 11 is coiled at 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 provided at a position near the bottom of 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.

[0036] As Figures 2 to 6 shown, a partition member 3 is provided 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 in contact with the inner wall of the tank body 1. The partition member 3 divides the inside 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 provided on the left and right sides of the tank body 1. A valve assembly is provided 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 provided on the spraying cylinder 5. A first driving assembly for driving the partition member 3 to move up and down is provided 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.

[0037] When the gas and liquid are dissolved, gas will be continuously introduced into the tank body 1 through the booster air pump, and the air pressure in the lower space of the partition 3 will gradually rise. When the air pressure in the lower space reaches the preset value, the control valve assembly is opened, and the driving assembly drives the partition 3 to move downward. The air pressure squeezes the liquid near the bottom in the lower space from the connecting pipe 4 to the upper space. Since there are more bubbles at the bottom of the tank body 1, the liquid at the bottom will be mixed and dissolved with the gas first, and the liquid with better dissolution effect at the bottom will be squeezed into the upper space, so that the remaining liquid in the lower space can be closer to the bubbles at the bottom, thereby improving the gas-liquid dissolution efficiency. In addition, during the downward movement of the partition 3, the water delivery assembly is controlled to transport the liquid at the top of the lower space to the injection tube 5 for injection, so that the liquid at the top is sprayed into the gas above the liquid surface, thereby improving the dissolution efficiency of the top liquid and gas, thereby achieving that the liquid at different positions in the tank body 1 can be better dissolved with the gas, thereby improving the overall dissolution rate.

[0038] The partition 3 is rotatably connected with the blocking member 6, which is in the shape of a cylinder with an opening at the bottom, and the blocking member 6 fits the inner wall of the partition cylinder 31. The partition cylinder 31 and the blocking member 6 are respectively provided with an air jet hole 61, and the partition 3 is provided with a driving component 2 for driving the blocking member 6 to rotate. When the partition 3 moves downward to a preset position, the valve component is closed, and the driving component 2 drives the blocking member 6 to rotate. When the blocking member 6 is connected with the air jet hole 61 on the partition 3, the gas in the lower space enters the upper space through the air jet hole 61.

[0039] When the partition 3 moves downward to the preset position, most of the liquid in the lower space has been squeezed into the upper space, and the amount of liquid remaining in the lower space is small and the liquid level is low. The liquid can be quickly mixed and dissolved with the bubbles at the bottom, while the amount of liquid in the upper space is large. At this time, the valve assembly is closed. When the blocking member 6 is connected to the jet hole 61 on the partition 3, the gas in the lower space will enter the upper space through the jet hole 61, so that the liquid in the upper space is mixed and dissolved with the gas again, so that the liquid and gas in the entire tank body 1 gradually reach a saturated state of dissolution.

[0040] like Figure 2 and Figure 3As shown in the figure, through holes one 15 and two 16 corresponding to the communication pipe 4 are respectively formed on the left and right sides of the tank body 1. The through hole one 15 is located at a position close to the bottom of the side wall of the tank body 1, and the through hole two 16 is located above the through hole one 15. A U-shaped plate 41 is slidably arranged vertically in the communication pipe 4. Through holes three 42 and four 43 are formed on the U-shaped plate 41. Magnets with opposite magnetic poles are arranged between the top of the communication 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 one 15 communicates with the through hole three 42, and the through hole two 16 communicates with the through hole four 43. Under the action of the air pressure, the liquid in the lower space enters the communication pipe 4 from the through hole one 15 and the through hole three 42, and enters the upper space from the through hole four 43 and the through hole two 16. When the partition member 3 moves downward to the preset position, the valve assembly drives the U-shaped plate 41 to move downward to block the through hole one 15 and the through hole two 16.

[0041] 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 provided on the partition ring 32. The movable rod 33 is located in the installation cavity 34 and penetrates through the partition 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.

[0042] 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 communication pipe 4 communicates with the inside of the tank body 1. When the partition member 3 moves downward to the preset position, the partition ring 32 of the partition member 3 presses down the second lever 45 to drive the U-shaped plate 41 to move downward, blocking the communication between the communication pipe 4 and the inside of the tank body 1.

[0043] As Figures 4 to 6 、 Fig. 9As shown, the water delivery assembly includes a motor 7, a mounting rod 71 and a spiral blade 72. The motor 7 is fixedly mounted on the cover 12. The mounting rod 71 is connected to the 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 in the injection tube 5. A connecting assembly is provided between the mounting rod 71 and the partition 3. The connecting assembly includes a connecting plate 73 and an insert rod 74. The connecting plate 73 is sleeved on the outer periphery of the mounting rod 71, and an annular groove is provided on the inner periphery of the connecting plate 73. A convex edge matching the annular groove extends from the outer periphery of the mounting rod 71. The insert rod 74 is vertically fixedly connected to the connecting plate 73. A sleeve rod 35 is fixedly connected to the top of the partition 3, and the insert rod 74 is inserted into the sleeve rod 35.

[0044] Four liquid storage chambers 53 are arranged at intervals on the outer circumference of the spray cylinder 5, and the spray hole 52 is connected to the liquid storage chamber 53, and the liquid storage chamber 53 is connected to the inside of the spray cylinder 5 through the connecting port 1 54. A baffle 8 located below the connecting port 1 54 is rotatably connected inside the spray cylinder 5, and the baffle 8 is connected to the mounting rod 71, and a connecting port 2 81 is opened on the baffle 8. When the motor 1 7 drives the mounting rod 71 to rotate, the spiral blade 72 on the mounting rod 71 transports the liquid near the top into the spray cylinder 5, and the baffle 8 is driven to rotate during the rotation of the mounting rod 71. When the connecting port 2 81 corresponds to the connecting port 1 54 up and down, the corresponding liquid storage chamber 53 is connected to the inside of the spray cylinder 5, and the liquid in the spray cylinder 5 enters the liquid storage chamber 53 and is sprayed from the spray hole 52 to above the liquid surface.

[0045] like Figure 4 , Figures 6 to 9 As shown, a vertically extending push rod 22 is provided at the bottom center of the tank body 1, and the push rod 22 is fixedly connected to the output shaft of the motor 2. The driving assembly 2 includes a clamping block 1 75 and a clamping block 2 62, wherein the clamping block 1 75 is spaced apart along the periphery of the mounting rod 71 and is fixedly connected to the mounting rod 71, and the clamping block 2 62 is spaced apart along the periphery of the mounting rod 71 and is 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 3 moves to the preset position, the second block 62 is located above the first block 75. When the partition 3 moves to the preset position, the mounting rod 71 presses on the push rod 22 and cannot continue to move downward. During the process of the partition 3 continuing to move downward, the blocking member 6 squeezes the spring, and the second block 62 on the blocking member 6 enters between two adjacent first blocks 75. As the mounting rod 71 rotates, the first block 75 and the second block 62 cooperate to drive the blocking member 6 to rotate, thereby realizing the connection between the jet hole 61 on the blocking member 6 and the jet hole 61 on the partition 3, and spraying the gas in the lower space into the upper space.

[0046] A gas-liquid dissolution method, using the gas-liquid dissolution device in the above embodiment, the gas-liquid dissolution method comprises the following steps: Add liquid into the tank body 1, and seal the cover body 12 tightly, control the booster air pump to pass gas into the exhaust pipe 11, and control the stirring assembly to stir; 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 a 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 lever 44 through the top plate 37 to drive the shaped plate 41 to move upward, so that the connecting pipe 4 is connected to the inside of the tank body 1, and the hydraulic telescopic cylinder 14 is controlled to drive the partition 3 to move downward. The air pressure squeezes the liquid near the bottom of the lower space from the connecting pipe 4 to 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. During the downward movement of the partition 3, the control motor 1 7 drives the mounting rod 71 to rotate, and the spiral blade 72 on the mounting rod 71 delivers the liquid near the top to the injection tube 5, and the mounting rod 71 drives the baffle 8 to rotate during the rotation. When the connecting port 2 81 corresponds to the connecting port 1 54, the corresponding liquid storage chamber 53 is connected to the inside of the injection tube 5, and the liquid in the injection tube 5 enters the liquid storage chamber 53 and is sprayed from the spray hole 52 to the top of the liquid surface, so that the sprayed liquid can fully contact and dissolve with the gas above the liquid surface. When the partition 3 continues to move downward until the mounting rod 71 contacts the push rod 22, the mounting rod 71 can no longer move downward, and the partition 3 drives the blocking member 6 to continue to move downward, and the block 2 62 on the blocking member 6 enters between the two adjacent blocks 1 75. At the same time, the partition 3 presses down the lever 2 45 to drive the shaped plate 41 to move downward, blocking the connection between the connecting pipe 4 and the inside of the tank body 1. As the mounting rod 71 rotates, the block 1 75 and the block 2 62 cooperate to drive the blocking member 6 to rotate. When the jet hole 61 on the blocking member 6 is opposite to the jet hole 61 on the partition 3, the gas in the lower space is sprayed into the liquid in the upper space.
