Description

Technical Field

[0001] The invention belongs to the field of bubble generation, in particular to a self-priming bubble generating device. Background Art

[0002] Directly discharging wastewater containing oily substances will cause harm to local water bodies and lead to aquatic organism diseases. The carcinogenic hydrocarbons in the wastewater will also affect human health through enrichment. In order to prevent the ecological damage, people have developed oil-water separation technology, among which the use of self-priming bubble generating devices to treat wastewater has the characteristics of better separation effect, faster separation speed and lower separation cost.

[0003] The principle of self-priming flotation is to use the impeller to rotate at high speed under the drive of the motor, forming a negative pressure on the impeller surface, and then sucking in air through the connection with the outside world. Under the stirring of the impeller, the air is broken into tiny bubbles, and then the pollutants are separated. There are many main influencing factors of self-priming bubble generation technology, including impeller diameter, opening size, impeller speed, impeller circumferential speed, impeller water filling depth, and the distance between the impeller and the guide vanes. Therefore, it is critical to develop an impeller parameter suitable for oil-water separation. Before it is put into production and use, it is necessary to conduct multiple experiments and replace equipment with different parameters to determine the optimal parameters. During the experiment, it is necessary to remove and replace the bubble generator several times. When the bubble generator is removed from the wastewater, some solution and bubbles will adhere to the pipe. In order to avoid wastewater and foam adhering to the pipe and affecting subsequent experimental results, the device needs to be cleaned.

[0004] To this end, the present invention provides a self-priming bubble generating device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a self-priming bubble generating device according to the present invention includes a pipeline for transmitting gas, and further includes:

[0007] a body fixedly connected to one end of the pipeline, the body being used to control the flow rate of the gas transported into the pipeline;

[0008] Containers for wastewater;

[0009] a gas-liquid mixer fixedly connected to one end of the pipeline, wherein an impeller is provided in the gas-liquid mixer; and

[0010] The cleaning part includes a circular shell slidably mounted on the pipe, and two groups of symmetrically distributed cleaning components are arranged inside the circular shell. The cleaning components include wiping cloths, and the cleaning components are semi-circular and used to clean the outer wall of the pipe.

[0011] Specifically, before use, the container is filled with wastewater, the parameters are set, and the gas-liquid mixer is passed through the round shell and placed in the container. The two cleaning components form a whole circle and surround the outside of the pipe. During the experiment, the gas-liquid mixer adopts a self-priming flotation structure. The impeller in the gas-liquid mixer rotates at high speed under the drive of the motor. A negative pressure is formed on the surface of the impeller. Air is inhaled through the connection with the pipe. Under the stirring of the impeller, the air is crushed into tiny bubbles to purify the wastewater. The staff records the purification effect. When conducting experiments with different parameters, the gas-liquid mixer needs to be replaced. When replacing, the pipe is removed from the wastewater, and the gas-liquid mixer is thus removed from the wastewater. At this time, some wastewater and bubbles will adhere to the outer wall of the pipe. By keeping the round shell fixed, the pipe slides upward relative to the cloth. At this time, the cloth can wipe off some of the wastewater and bubbles attached to the outer wall of the pipe, thereby improving the cleanliness of the device and avoiding wastewater and foam from adhering to the pipe, which affects subsequent experimental results.

[0012] Preferably, the cleaning assembly further comprises a No. 1 plate and a No. 2 plate, a number of plugs being fixedly connected to the No. 1 plate, the two ends of the wiping cloth being respectively clamped between the No. 1 plate and the No. 2 plate, the No. 1 plate and the No. 2 plate being elastic plates, the cleaning assembly being in the shape of a flat plate, and being in the shape of a semicircle after the No. 1 plate is bent, and the No. 1 plate and the No. 2 plate are surrounded by rounded edges.

[0013] Specifically, plates No. 1 and No. 2 use deformable and repositionable 65 manganese steel sheets. The 65 manganese steel sheets have two shapes: semicircular and straight. For specific shape changes, please refer to the snap ring. When plates No. 1 and No. 2 are in a bent state, they can be fixed on the outside of the pipe. When the wiping cloth is damaged due to long-term use, the plug on plate No. 1 is pulled out from plate No. 2, and the wiping cloth wrapped around the outer layer of plate No. 1 is removed and replaced. The new wiping cloth is wrapped around the outer layer of plate No. 1, and both ends of the wiping cloth pass through the plug. Plate No. 1 is fixed to plate No. 2 through the plug. There is no need to replace the entire plate, which saves costs.

[0014] Preferably, the cleaning unit further comprises:

[0015] a round cover detachably connected to the round shell; and

[0018] Specifically, when the experimental parameters need to be changed multiple times during the experiment, the bubble generating device needs to be used multiple times within a period of time. By setting up multiple cleaning components, the used cleaning components can be replaced. There is no need to clean the rag after each wiping. The used cleaning components can be collected together. After the experiment, all used cleaning components can be cleaned together. It is very convenient to use. The round cover can be set to prevent the cleaning components from being contaminated. At the same time, the long hole can be used to observe the number of cleaning components in the round shell for timely replacement.

[0019] Preferably, the cleaning unit further comprises:

[0020] A plurality of circular plates for pushing the cleaning assembly to move, wherein the circular plates are connected to the circular shell via springs and are slidably connected to the circular rod;

[0021] A plurality of movable rods movably mounted inside the circular shell, the movable rods being used to move the cleaning assembly; and

[0022] Several fixing components are arranged on the No. 1 slide, and the fixing components include an insertion rod and a rotating rod.

The connecting rod is rotatably connected to the rotating rod, and a torsion spring is provided between the connecting rod and the rotating rod.

[0023] Specifically, after the pipe is cleaned, the movable rod is pushed to move, so that the cleaning component moves toward the center of the circular shell, driving the rotating rod to rotate toward the vertical plane. After the rotating rod rotates 90 degrees, the push rod continues to push the used cleaning component to move until the used cleaning component falls off the circular rod. At the same time, the cleaning component behind moves toward the center of the circular shell under the thrust of the spring of the circular plate. After the used cleaning component falls, the rotating rod returns to its original state under the action of the torsion spring. By setting the circular plate, the cleaning component can be replaced automatically, which is convenient to use.

[0026] A plurality of push rods are rotatably connected to the side walls of the insertion rod, and the other ends of the push rods are rotatably connected to the baffle.

[0027] Specifically, in the initial state, the elastic force of the spring connecting the insertion rod and the round rod is smaller than the elastic force of the torsion spring between the connecting rod and the rotating rod, and the top of the baffle is located on the outside of the round rod. When the used cleaning component moves toward the center, the rotating rod is pulled by the used cleaning component, driving the insertion rod to move toward the center of the circle first. At this time, the push rod moves and rotates, causing the baffle to slide in the direction away from the insertion rod. When the elastic force of the spring connecting the insertion rod and the round rod is greater than the elastic force of the torsion spring between the connecting rod and the rotating rod, the rotating rod rotates, and the movable rod pushes the used cleaning component off the round rod. At this time, the insertion rod is no longer under force and moves forward under the pull of the spring. When the cleaning rod is cleaned, the cleaning element is moved to the left of the cleaning rod and the cleaning element is cleaned, and the cleaning element is moved to the right of the cleaning rod, and the cleaning element is moved to the right of the cleaning rod. When the cleaning rod is cleaned, the cleaning element is moved to the left of the cleaning rod and the cleaning element is cleaned. When the cleaning rod is cleaned, the cleaning element is moved to the right of the cleaning rod, and the cleaning element is moved to the right of the cleaning rod. When the cleaning rod is cleaned, the cleaning element is moved to the left of the cleaning rod and the cleaning element is cleaned.

[0028] Preferably, the device further comprises a collecting unit, wherein the collecting unit comprises:

[0029] Two collection boxes detachably connected to the bottom of the circular shell; and

[0030] A moving rod is movably connected to the collection box, the moving rod is connected to the collection box through a spring, the lower end of the moving rod is inclined, and the moving rod is used to suspend the cleaning assembly.

[0031] Specifically, when replacing the cleaning component, the moving rod moves until the center of the circle at the top is aligned with the center of the circle of the insertion rod, and the used cleaning component is pushed from the round rod to the moving rod by the movable rod. Under the action of gravity, the used cleaning component slides downward until it is located at the lower end of the moving rod; by setting up a collection box, the used cleaning components can be collected, which is convenient to use.

[0036] A plurality of push plates slidably connected to the grooves, the push plates being connected to the grooves via springs, circular plates being slidably connected to the push plates, and the push plates being connected to the circular blocks via the circular plates; and

[0037] Two switches are fixedly connected to the collecting box, and the switches are located within the moving range of the moving rod. The switches are used to control the extension and retraction of the electric telescopic rod.

[0038] Specifically, a circular hole corresponding to the ball is opened in the circular plate. When the moving rod moves into the circular shell, the switch is turned on and the electric telescopic rod is expanded until the ball on the round block is embedded in the circular hole of the circular plate. At this time, the electric telescopic rod is connected to the push plate. When the moving rod returns to its initial state, the switch is turned off. At this time, the electric telescopic rod contracts, driving the push plate to move in a direction away from the center of the circle. The push plate contacts the used cleaning component and pushes the used cleaning component from a curved shape to a straight shape. The electric telescopic rod continues to contract, and the push plate is subjected to the reaction force of the used cleaning component and falls off the circular plate, and is pulled back to its original position by the spring. By setting the push plate, the used cleaning component can be pushed from a curved shape to a straight shape, so that the collection box can store more used cleaning components, thereby improving the utilization rate of the space in the collection box.

[0039] Preferably, it further comprises a support portion, wherein the support portion comprises:

[0040] A plurality of support frames are movably connected to the bottom of the circular shell, and the support frames are used to support the cleaning part.

[0041] Specifically, when the staff is in the laboratory, they install the cleaning component to the outside of the pipeline, changing the cleaning component from a straight plate to a curved shape. At this time, the cleaning component is in close contact with the pipeline, and a support frame is set up to fix the gas-liquid mixer of the pipeline at any height of the solution, while preventing the pipeline from slipping out of the container due to collision.

[0042] Preferably, the support portion further includes:

[0043] A number one circular ring fixedly connected to one end of the support frame;

The connection between the curved rods and the No. 1 circular ring is far away from the connection between the curved rods and the No. 2 circular ring.

[0046] Specifically, rotating the No. 2 ring drives the curved rod to rotate until it is in close contact with the outer wall of the container. By setting the curved rod, it can adapt to containers of different sizes, etc., which is more practical. At the same time, the curved rod is located on the outer wall of the container and does not occupy the area of ​​the desktop, etc., making it more convenient to use.

[0047] Preferably, a T-bar is fixedly connected to the top of the support frame, and a plurality of fixed cylinders are fixedly connected to the bottom plate of the round shell. A cylinder is rotatably connected to the fixed cylinder, and a rotating cylinder is connected to the inside of the cylinder through a spring. A push cylinder is slidably connected inside the cylinder, and the rotating cylinder is slidably connected to the cylinder, and the rotating cylinder is inserted into the fixed cylinder.

[0048] Specifically, by providing a detachable bracket, it is more convenient to use when the components need to be replenished or taken away for cleaning. For some larger or smaller containers, when the No. 1 ring cannot pass through, it can be removed, which is more practical. At the same time, it can be removed from the round shell for easy storage.

[0049] The beneficial effects of the present invention are as follows:

DETAILED DESCRIPTION

[0068] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example 1

[0069] like Figure 1-11As shown, a self-priming bubble generating device according to an embodiment of the present invention includes a pipeline 1, wherein the pipeline 1 is used to transmit gas, and further includes:

[0070] A body 11 fixedly connected to one end of the pipeline 1, the body 11 is used to control the flow rate of the gas transported into the pipeline 1;

[0071] Container for holding wastewater 5;

[0072] a gas-liquid mixer 12 fixedly connected to the other end of the pipeline 1, wherein the gas-liquid mixer 12 is provided with an impeller; and

[0073] The cleaning part 2 includes a circular shell 22 slidably mounted on the pipe 1, and two groups of symmetrically distributed cleaning components 21 are arranged inside the circular shell 22. The cleaning components 21 include a wiping cloth 211, and the cleaning components 21 are semicircular. The wiping cloth 211 is used to clean the outer wall of the pipe 1.

[0074] Specifically, before use, the container 5 is filled with wastewater, and the parameters of the gas-liquid mixer 12 are set. The gas-liquid mixer 12 is passed through the round shell 22 and placed in the container 5. The two cleaning components 21 form a full circle and surround the outside of the pipe 1. During the experiment, the gas-liquid mixer 12 adopts a self-priming air flotation structure. The impeller in the gas-liquid mixer 12 rotates at a high speed under the drive of the motor. A negative pressure is formed on the surface of the impeller. Air is sucked in through the connection with the pipe 1. Under the stirring of the impeller, the air is crushed into tiny bubbles to purify the wastewater. The staff records the net effect; when conducting experiments with different parameters, the gas-liquid mixer 12 needs to be replaced. When replacing, the pipe 1 is taken out of the wastewater, and thus the gas-liquid mixer 12 is taken out of the wastewater. At this time, part of the wastewater and bubbles will adhere to the outer wall of the pipe 1. By keeping the round shell 22 fixed, the pipe 1 slides upward relative to the wiping cloth 211. At this time, the wiping cloth 211 can wipe off part of the wastewater and bubbles attached to the outer wall of the pipe 1, thereby improving the cleanliness of the device and preventing wastewater and foam from adhering to the pipe 1, which may affect subsequent experimental results.

[0075] like Figure 5 As shown, the cleaning component 21 also includes a No. 1 plate 212 and a No. 2 plate 213. A number of plugs 2121 are fixedly connected to the No. 1 plate 212. The two ends of the wiping cloth 211 are respectively clamped between the No. 1 plate 212 and the No. 2 plate 213. The No. 1 plate 212 and the No. 2 plate 213 are both elastic plates. The cleaning component 21 is flat. After the No. 1 plate 212 is bent, the cleaning component 21 is semicircular. The No. 1 plate 212 and the No. 2 plate 213 are surrounded by round edges.

[0076] Specifically, plate No. 1 212 and plate No. 2 213 use deformable and repositionable 65 manganese steel sheets. The 65 manganese steel sheets have two forms: semicircular and straight. The specific form changes can refer to the snap ring. When plate No. 1 212 and plate No. 2 213 are in a bent state, they can be fixed on the outside of the pipe 1. When the wiping cloth 211 is damaged due to long-term use, the plug 2121 on plate No. 1 212 is pulled out from plate No. 2 213, and the wiping cloth 211 wrapped around the outer layer of plate No. 1 212 is removed and replaced. The new wiping cloth 211 is wrapped around the outer layer of plate No. 1 212. The two ends of the wiping cloth 211 pass through the plug 2121. Plate No. 1 212 is fixed to plate No. 2 213 through the plug 2121. There is no need to replace the entire plate, which saves more costs.

[0077] like Figures 2 to 9 As shown, the cleaning unit 2 further includes:

[0078] A round cover 29 detachably connected to the round shell 22; and

[0079] A plurality of round rods 23 are fixedly connected to the interior of the round shell 22, and a plurality of cleaning components 21 are slidably mounted on the round rods 23;

[0080] The round cover 29 is provided with a long hole for observing the cleaning assembly 21 on the round rod 23 . The round rod 23 is provided with a first chute 231 and a second chute 232 .

[0081] Specifically, when the experimental parameters need to be changed multiple times during the experiment, the bubble generating device needs to be used multiple times within a period of time. By setting up multiple cleaning components 21, the used cleaning components 21 can be replaced, and there is no need to clean the wiping cloth 211 after each wiping. The used cleaning components 21 can be collected together. After the experiment, all the used cleaning components 21 can be cleaned together, which is very convenient to use. By setting up the round cover 29, the cleaning component 21 can be prevented from being contaminated. At the same time, the long hole can be used to observe the number of cleaning components 21 in the round shell 22 for timely replacement.

[0082] like Figures 2 to 9 As shown, the cleaning unit 2 further includes:

[0083] A plurality of circular plates 24 for pushing the cleaning assembly 21 to move, wherein the circular plates 24 are connected to the circular shell 22 via springs, and the circular plates 24 are slidably connected to the circular rod 23;

[0084] A plurality of movable rods 25 movably mounted inside the circular shell 22 , the movable rods 25 being used to move the cleaning assembly 21 ; and

[0085] Several fixing components 26 are arranged on the No. 1 slide groove 231, and the fixing components 26 include an insertion rod 261 and a rotating rod 262. The insertion rod 261 is slidingly connected to the No. 1 slide groove 231 through a spring, and one end of the insertion rod 261 is rotatably connected to several connecting rods 263. The connecting rod 263 is rotatably connected to the rotating rod 262, and a torsion spring is provided between the connecting rod 263 and the rotating rod 262.

[0086] Specifically, after the pipe 1 is cleaned, the movable rod 25 is pushed to move, so that the cleaning component 21 moves toward the center of the circular shell 22, driving the rotating rod 262 to rotate toward the vertical plane. After the rotating rod 262 rotates 90 degrees, the movable rod 25 continues to push the used cleaning component 21 to move until the used cleaning component 21 falls off the circular rod 23. At the same time, the cleaning component behind moves toward the center of the circular shell 22 under the thrust of the spring of the circular plate 24. After the used cleaning component 21 falls, the rotating rod 262 returns to its original state under the action of the torsion spring; by setting the circular plate 24, the cleaning component 21 can be replaced automatically, which is convenient to use.

[0087] like Figures 5 to 9 As shown, the cleaning unit 2 further includes:

[0088] a plurality of baffles 27 slidably connected to the second chute 232 , wherein the top of the baffles 27 is triangular; and

[0089] A plurality of push rods 28 are rotatably connected to the side wall of the inserting rod 261 , and the other end of the push rod 28 is rotatably connected to the baffle 27 .

[0090] Specifically, the elastic force of the spring connecting the inserting rod 261 and the circular rod 23 is smaller than the elastic force of the torsion spring between the connecting rod 263 and the rotating rod 262 in the initial state, and the top end of the baffle 27 is located outside the circular rod 23. When the used cleaning assembly 21 moves towards the center, the rotating rod 262 is pulled by the used cleaning assembly 21, and the inserting rod 261 is first moved towards the center, at this time, the push rod 28 moves and rotates, so that the baffle 27 slides away from the inserting rod 261. When the elastic force of the spring connecting the inserting rod 261 and the circular rod 23 is greater than the elastic force of the torsion spring between the connecting rod 263 and the rotating rod 262, the rotating rod 262 rotates, and the movable rod 25 pushes the used cleaning assembly 21 off the circular rod 23. At this time, the inserting rod 261 is no longer under stress, and moves away from the center under the pulling of the spring. At the same time, the rotating rod 262 returns to the original state, at this time, the push rod 28 moves and rotates, so that the baffle 27 slides towards the inserting rod 261. When the baffle 27 moves completely into the circular rod 23, an unused cleaning assembly 21 close to the baffle 27 moves between the baffle 27 and the rotating rod 262. When the inserting rod 261 returns to the initial state, part of the baffle 27 moves outside the circular rod 23. By arranging the baffle 27, the working cleaning assembly 21 and the unused cleaning assembly 21 are isolated, which avoids the unused cleaning assembly 21 being pressed by the pipeline 1 during wiping, and also avoids the unused cleaning assembly 21 falling off the circular rod 23 when replacing the cleaning assembly 21.

[0091] As shown in Figure 10 , the collecting part 3 further comprises:

[0092] two collecting boxes 31 detachably connected to the bottom of the circular shell 22; and

[0093] a movable rod 32 movably connected in the collecting box 31, the movable rod 32 being connected to the collecting box 31 by a spring, the lower end of the movable rod 32 being inclined, and the movable rod 32 being used for hanging the cleaning assembly 21.

[0094] Specifically, when replacing the cleaning assembly 21, the movable rod 32 moves until the center of the top end is aligned with the center of the inserting rod 261, and the used cleaning assembly 21 is pushed by the movable rod 25 from the circular rod 23 to the movable rod 32. Under the action of gravity, the used cleaning assembly 21 slides downwards until it is located at the lower end of the movable rod 32. By arranging the collecting box 31, the used cleaning assembly 21 is collected, which is convenient to use.

[0095] As shown in Figure 11 , the collecting part 3 further comprises:

[0096] a groove 37 opened in the sidewall of the collecting box 31;

[0097] a plurality of electric telescopic rods 33 mounted on one end of the groove 37;

[0098] A round block 34 is fixedly connected to the top of the electric telescopic rod 33, and the side wall of the round block 34 is connected to a plurality of balls 341 via springs;

[0100] Two switches 36 are fixedly connected to the collecting box 31 . The switches 36 are located within the moving range of the moving rod 32 . The switches 36 are used to control the extension and retraction of the electric telescopic rod 33 .

[0101] Specifically, a circular hole corresponding to the ball 341 is opened in the third ring 351. When the moving rod 32 moves into the circular shell 22, the switch 36 is turned on, and the electric telescopic rod 33 is expanded until the ball 341 on the round block 34 is embedded in the circular hole of the third ring 351. At this time, the electric telescopic rod 33 is connected to the push plate 35. When the moving rod 32 returns to its initial state, the switch 36 is turned off. At this time, the electric telescopic rod 33 contracts, driving the push plate 35 to move in a direction away from the center of the circle. The push plate 35 and the push plate 35 are connected. The used cleaning component 21 contacts the used cleaning component 21 and pushes the used cleaning component 21 from the curved shape to the straight plate shape. The electric telescopic rod 33 continues to shrink, and the push plate 35 is subjected to the reaction force of the used cleaning component 21 and falls off from the circular plate 24, and is pulled back to its original position by the spring. By setting the push plate 35, the used cleaning component 21 can be pushed from the curved shape to the straight plate shape, so that the collection box 31 can store more used cleaning components 21, thereby improving the utilization rate of the space in the collection box 31.

[0102] like Figure 2 As shown, it also includes a support portion 4, and the support portion 4 includes:

[0103] A plurality of support frames 41 are movably connected to the bottom of the circular shell 22 , and the support frames 41 are used to support the cleaning part 2 .

[0104] Specifically, when the staff is in the laboratory, they install the cleaning component 21 to the outside of the pipeline 1, changing the cleaning component 21 from a straight plate shape to a curved shape. At this time, the cleaning component 21 is in close contact with the pipeline 1, and a support frame 41 is set. The gas-liquid mixer 12 of the pipeline 1 can be fixed at any height of the solution, and at the same time, it can prevent the pipeline 1 from slipping out of the container 5 due to collision.

[0105] like Figure 2 As shown, the support portion 4 further includes:

[0106] A first circular ring 42 fixedly connected to one end of the support frame 41;

[0107] Rotating the second ring 43 connected to the outside of the first ring 42; and

[0108] A plurality of curved rods 44 are rotatably connected to the upper end of the second circular ring 43 . The curved rods 44 are rotatably connected to the first circular ring 42 . The connection between the curved rods 44 and the first circular ring 42 is away from the connection between the curved rods 44 and the second circular ring 43 .

[0109] Specifically, rotating the second ring 43 drives the curved rod 44 to rotate until it is in close contact with the outer wall of the container 5. By setting the curved rod 44, it can adapt to containers 5 of different sizes, etc., which is more practical. At the same time, the curved rod 44 is located on the outer wall of the container 5 and does not occupy the area of ​​the desktop, etc., making it more convenient to use. Example 2

[0110] like Figure 12 As shown, compared with Example 1, another embodiment of the present invention is: the top of the support frame 41 is fixedly connected to a T-bar 411, and a plurality of fixed cylinders 222 are fixedly connected to the bottom plate of the round shell 22, and a cylinder 224 is rotatably connected to the fixed cylinder 222, and the interior of the cylinder 224 is connected to a rotating cylinder 223 through a spring, and a push cylinder 225 is slidably connected inside the cylinder 224, and the rotating cylinder 223 is slidably connected to the cylinder 224, and the rotating cylinder 223 is plugged into the fixed cylinder 222.

[0111] Specifically, by providing a detachable bracket, it is more convenient to use when it is necessary to replenish or remove the cleaning component 21. For some larger or smaller containers 5, when the No. 1 ring 42 cannot pass through, it can be removed, which is more practical. At the same time, it can be removed from the round shell 22 for easy storage.

[0112] Working steps

[0113] Step 1. In the initial state, the two sets of cleaning components 21 are flat, and the distance between the two sets of cleaning components 21 is large. The pipeline 1 and the gas-liquid mixer 12 are placed into the container 5 through the cleaning components 21. The second ring 43 is rotated to drive the curved rod 44 to rotate and extend until the curved rod 44 is in close contact with the outer wall of the container 5. The first plate 212 and the second plate 213 are moved to change the first plate 212 and the second plate 213 from a flat state to a curved state. The cleaning component 21 is fixed to the outside of the pipeline 1. Of course, the pipeline 1 can also be pulled upward to fix the gas-liquid mixer 12 at a specified height of the solution, and then the experiment is carried out;

[0114] Step 2: After the experiment is finished, pull the pipe 1 upwards, and the cleaning cloth 211 in the cleaning component 21 can wipe the foam and solution on the pipe 1. Clean and replace the cleaning cloth 211 according to the usage of the cleaning cloth 211;

[0115] Step 3: When replacing the cleaning assembly 21, push the movable rod 25 to move the cleaning assembly 21 toward the center, driving the rotating rod 262 to rotate in the vertical plane. After the rotating rod 262 rotates 90 degrees, the old cleaning assembly 21 falls off the round rod 23. At the same time, the unused cleaning assembly 21 moves toward the center of the circle under the thrust of the spring of the circular plate 24. The new cleaning assembly 21 surrounds the outside of the pipe 1 for the next round of cleaning.

[0116] Step 4: The moving rod 32 moves until the center of the circle at the top is aligned with the center of the circle of the inserting rod 261. The used cleaning component 21 is pushed from the round rod 23 to the moving rod 32 by the movable rod 25. Under the action of gravity, the cleaning component 21 slides downward along the moving rod 32 to the bottom end, completing the operation of collecting the used cleaning component 21.

[0117] When the moving rod 32 moves into the circular shell 22, the switch 36 is turned on and the electric telescopic rod 33 is unfolded until the ball 341 on the round block 34 is embedded in the circular hole of the third ring 351. At this time, the electric telescopic rod 33 is connected to the push plate 35. When the moving rod 32 returns to the initial state, the switch 36 is turned off. At this time, the electric telescopic rod 33 contracts, driving the push plate 35 to move in the direction away from the center of the circle. The push plate 35 contacts the used cleaning component 21 and pushes the used cleaning component 21 from the curved shape to the straight plate shape. The electric telescopic rod 33 continues to contract, and the push plate 35 is subjected to the reaction force of the cleaning component 21 and falls off from the circular plate 24. It is pulled back to its original position by the spring. By changing the used cleaning component 21 from the curved shape to the straight plate shape, it is convenient to collect and stack the used cleaning components 21, and more used cleaning components 21 can be collected.

[0118] Step 6: Repeat steps 1 to 5. During multiple experiments, the automatic cleaning and automatic collection work of the cleaning component 21 is automatically cycled.
