[0036] In the technical solution, when the calcium carbonate is disintegrated, first, the CaCO3 suspension (water or ethanol as medium) is sent into the mixing cylinder 1, then the stearic acid is dissolved in hot ethanol (60-70 DEG C) to form a 10% solution, the solution is sent into the connecting pipe 14 through the liquid supply pipe 4, and is discharged from the liquid injection hole 5 through the connecting pipe 14, the flow distribution groove 15, the flow guide groove 16 and the liquid injection groove 17, so that the solution is mixed with the CaCO3 suspension, at the same time, the first gear 12 is driven to rotate by the servo motor 11, the second gear 13 is driven to rotate by the first gear 12, the rotating shaft 2 is driven to rotate by the second gear 13, and the stirring rod 3 is driven to rotate by the rotating shaft 2, so that the stirring rod 3 stirs the mixed liquid, the solution is fully mixed and reacted, and after 1-2 hours, the calcium carbonate disintegration treatment is completed through filtering, drying and grinding.

[0037] When the solution is discharged into the CaCO3 suspension through the liquid injection hole 5, the sliding rod 8 is driven to rotate by the rotation of the rotating shaft 2, so that the sliding rod 8 slides along the annular sliding groove 7, the first sliding protrusion 19 is driven to slide along the track groove 20 by the sliding rod 8, when the first sliding protrusion 19 slides along the rising part 2021 of the wave part 202, the first sliding protrusion 19 drives the sliding rod 8 to move upward, the sliding rod 8 drives the stirring rod 3 to move upward, and the liquid injection hole 5 is driven to move upward by the stirring rod 3, when the first sliding protrusion 19 slides along the falling part 2022 of the wave part 202, the first sliding protrusion 19 drives the sliding rod 8 to move downward to reset, so that the stirring rod 3 drives the liquid injection hole 5 to move downward to reset, so that the liquid injection hole 5 can move up and down reciprocatingly when the stirring rod 3 is driven to rotate circumferentially by the rotating shaft 2, so that the solution can be more uniformly added into the CaCO3 suspension, and the reaction is more sufficient.

[0038] In the technical solution, as Figure 3As shown, the stirring rod 3 is provided with two layers on the surface of the rotating shaft 2, each layer of the stirring rod 3 is uniformly provided with four, the slide rod 8 is provided with four groups corresponding to the stirring rod 3, and the wave part 202 is provided with four corresponding to the slide rod 8. Four slide rods 8 move synchronously into four wave parts 202, so that the four stirring rods 3 can synchronously reciprocate up and down, and the two stirring rods 3 on the upper and lower sides are fixed through the connecting column 52. The hollow groove 53 is provided in the connecting column 52 and is in communication with the liquid injection groove 17, and the liquid can be transported from the upper liquid injection groove 17 to the lower liquid injection groove 17 through the hollow groove 53, so that the prepared solution can be discharged from the lower liquid injection hole 5.

[0039] In example two, due to the increase of the reaction rate, the rate of CO2 generation is increased, which can cause that the CO2 bubbles generated in the mixing barrel 1 cannot be fully discharged, and the CO2 bubble residue is easy to appear. In order to solve this problem, the embodiment is improved on the basis of example one. For details, please refer to Figures 1-11 The inside of the stirring rod 3 is provided with an air suction groove 21, the end of the air suction groove 21 is fixed with a semi-permeable membrane 22, the air suction groove 21 is provided with a gas conveying pipe 23 in communication, the surface of the slide rod 8 is fixed with a lifting plate 24, the surface of the rotating shaft 2 is provided with a limiting groove 25 for the sliding of the lifting plate 24, the inside of the rotating shaft 2 is provided with a gas cavity 26, the first piston plate 27 is slidably arranged in the gas cavity 26, the connecting rod 28 is fixed between the first piston plate 27 and the lifting plate 24, the bottom end of the gas cavity 26 is provided with a first air inlet groove 29, the gas conveying pipe 23 is slidably arranged in the first air inlet groove 29, the inside of the rotating shaft 2 is provided with an air outlet groove 30 in communication with the gas cavity 26, and the top end of the air outlet groove 30 is provided with an air exhaust hole 31.

[0040] The first one-way valve 32 is arranged in the air suction groove 21, and the second one-way valve 33 is arranged in the first air inlet groove 29.

[0041] In the technical solution, when the sliding rod 8 moves upward, the lifting plate 24 is driven to move upward, the lifting plate 24 drives the connecting rod 28 to move upward, the connecting rod 28 drives the first piston plate 27 to move upward in the air cavity 26, so that the bottom of the air cavity 26 generates negative pressure, so that the air cavity 26 inhales air from the outside through the first air inlet groove 29, the gas conveying pipe 23 and the air inlet groove 21, and the semi-permeable membrane 22 is arranged to block the liquid and only allow gas to pass through, so that the CO2 gas generated in the mixed liquid is sucked into the air cavity 26, and then the sliding rod 8 moves downward, the lifting plate 24 is driven to move downward, the lifting plate 24 drives the connecting rod 28 to move downward, the connecting rod 28 drives the first piston plate 27 to move downward in the air cavity 26, and the first piston plate 27 discharges the gas in the air cavity 26 through the air outlet groove 30 and the air outlet hole 31, through the above process, in the process of reciprocating movement of the stirring rod 3, the first piston plate 27 reciprocates in the air cavity 26, and the CO2 gas in the mixed liquid can be sucked out and discharged, so as to reduce the residual CO2 gas in the mixed liquid.

[0042] In the technical solution, the semi-permeable membrane 22 is a prior art which can separate gas and liquid, and is not the innovation point of the application, and will not be described in detail. The first one-way valve 32 is arranged to allow gas to enter the air cavity 26 through the air inlet groove 21, and cannot discharge gas from the air inlet groove 21 to the outside. The second one-way valve 33 is arranged to allow gas to be discharged from the air outlet hole 31 through the air outlet groove 30, and cannot allow gas to enter the air cavity 26 through the air outlet groove 30. Hollow crossbars 54 are fixed between the ends of each layer of stirring rods 3, the hollow crossbars 54 are slidably arranged in the rotating shaft 2, the air inlet groove 21 is communicated with the gas conveying pipe 23 through the hollow crossbar 54, and the air cavity 26, the first piston plate 27 and other structures are arranged at each layer of stirring rods 3 for air suction treatment, and the lifting plate 24 is arranged on the connecting column 52 for driving the first piston plate 27 at the corresponding position to move.

[0043] In the embodiment three, when the residual CO2 gas in the mixed liquid is sucked, most of the CO2 gas is directly discharged from the liquid surface, only a small amount of CO2 gas remains in the mixed liquid, so that the air inlet groove 21 cannot always suck CO2 gas, and the gas supply in the air cavity 26 is insufficient. At this time, the air cavity 26 continues to inhale air, which increases the negative pressure in the air cavity 26, and the negative pressure acting on the semi-permeable membrane 22 also increases. If the semi-permeable membrane 22 is always in a high negative pressure state, the semi-permeable membrane 22 is easy to be damaged, thereby reducing the service life of the semi-permeable membrane 22. To solve this problem, the embodiment is improved on the basis of the embodiment two, and specific improvements can be known from the Figures 1-11, one side of the air cavity 26 is provided with a pressure relief chamber 34, the inside of the pressure relief chamber 34 is elastically provided with a second piston plate 35, the inside of the rotating shaft 2 is provided with a second air inlet groove 36 communicated with the pressure relief chamber 34, the end of the second air inlet groove 36 is provided with an air inlet 37, the inside of the second air inlet groove 36 is inserted with a blocking plate 38, the inside of the rotating shaft 2 is provided with a driving assembly for driving the blocking plate 38 to move to open the second air inlet groove 36;

[0044] The inner wall of the pressure relief chamber 34 is fixed with a telescopic rod 39, the circumference of the telescopic rod 39 is sleeved with a first spring 40, the two ends of the first spring 40 are fixed between the second piston plate 35 and the bottom wall of the pressure relief chamber 34 respectively;

[0045] The driving assembly comprises a first moving groove 41 opened in the inside of the rotating shaft 2, the inside of the first moving groove 41 is slidably provided with a moving block 42, the second spring 43 is fixed between the moving block 42 and the inner wall of the first moving groove 41, the blocking plate 38 is slidably connected with the moving block 42, the end of the blocking plate 38 is fixed with a second sliding protrusion 44, the inside of the moving block 42 is provided with an inclined groove 45 for the second sliding protrusion 44 to slide.

[0046] In the technical solution, when the rotating shaft 2 rotates, due to the centrifugal force, as shown in Figure 10 , the moving block 42 moves left in the first moving groove 41, the moving block 42 moves left to make the blocking plate 38 slide relative to the moving block 42, the blocking plate 38 drives the second sliding protrusion 44 to slide along the inclined groove 45, so that the second sliding protrusion 44 drives the blocking plate 38 to move downward to open the second air inlet groove 36; when the first piston plate 27 moves upward in the air cavity 26, the air cavity 26 inhales, when the negative pressure in the air cavity 26 increases, the second piston plate 35 is adsorbed to move upward along the pressure relief chamber 34 by the action of negative pressure, the second piston plate 35 moves upward to stretch the first spring 40, so that the first spring 40 stores energy, until the second piston plate 35 moves upward to communicate the air cavity 26, the pressure relief chamber 34 and the second air inlet groove 36, at this time, the negative pressure acts on the second air inlet groove 36 to inhale gas from the air inlet 37, so as to balance the pressure in the air cavity 26, when the negative pressure is balanced, the first spring 40 releases, the second piston plate 35 moves downward to block the air cavity 26, the pressure relief chamber 34 and the second air inlet groove 36, through the up-down reciprocating movement of the second piston plate 35, when the negative pressure in the air cavity 26 is large, the air pressure in the air cavity 26 is balanced, so as to reduce the large negative pressure at the semi-permeable membrane 22, increase the protection of the semi-permeable membrane 22, and increase the service life of the semi-permeable membrane 22;

[0047] The second spring 43 causes the moving block 42 to move to the left at different distances depending on the centrifugal force, which in turn causes the second sliding protrusion 44 to slide at different distances along the inclined groove 45. This results in different opening diameters of the second air inlet groove 36 by the sealing plate 38. Consequently, the larger the centrifugal force, the larger the opening of the second air inlet groove 36. When the centrifugal force is large, the rotation speed of the shaft 2 is faster, leading to a faster suction speed inside the air chamber 26. When the suction speed is fast, a large negative pressure is easily generated inside the air chamber 26, at which point the opening of the second air inlet groove 36 is smaller. The larger opening of the second piston plate 35 allows for faster balance of the negative pressure inside the air chamber 26 when the second piston plate 35 connects the air chamber 26, the pressure relief chamber 34, and the second air inlet groove 36, further reducing the damage of the negative pressure to the semi-permeable membrane 22. In addition, when the opening of the second air inlet groove 36 is larger, the rate of negative pressure balance inside the air chamber 26 increases due to the increased air intake. The faster rate of negative pressure balance inside the air chamber 26 reduces the negative pressure acting on the second piston plate 35, thereby reducing the amplitude of the up-and-down reciprocating motion of the second piston plate 35 and reducing the wear of the second piston plate 35.

[0048] In this technical solution, the telescopic rod 39 allows the second piston plate 35 to move only vertically up and down, making it convenient for the second piston plate 35 to return to the pressure relief chamber 34 after moving upward. The telescopic rod 39 includes an inner rod and an outer rod that slide against each other. The outer rod is sleeved on the outside of the inner rod. The telescopic rod 39 can be telescopic by sliding the inner rod relative to the outer rod.

[0049] Example 4: This example presents another technical solution for the driving component. For details, please refer to [link / reference needed]. Figures 1-11 The drive assembly includes a second moving groove 46 opened inside the rotating shaft 2. An inclined block 47 is slidably arranged inside the second moving groove 46. A third spring 48 is fixed between the inclined block 47 and the inner wall of the second moving groove 46. A sealing plate 38 is provided with a through groove 49 for communicating with the second air inlet groove 36. An abutting block 50 for abutting against the inclined block 47 is fixed at the bottom end of the sealing plate 38. A fourth spring 51 is fixed between the top end of the sealing plate 38 and the inner wall of the rotating shaft 2.

[0050] In this technical solution, when the rotating shaft 2 rotates, due to the centrifugal force, such as Figure 11As shown, the inclined block 47 moves left inside the second moving groove 46, the inclined block 47 moves left and collides with the collision block 50, which makes the collision block 50 move up along the surface of the inclined block 47, the collision block 50 drives the blocking plate 38 to move up, the blocking plate 38 drives the through groove 49 to move up, and the third spring 48 is compressed and stored, the through groove 49 moves up to open the second air inlet groove 36, and the fourth spring 51 is arranged, so that the inclined block 47 moves left by different distances under different centrifugal forces, the collision block 50 slides along the inclined groove 45 by different distances, the blocking plate 38 drives the through groove 49 to move by different distances, so that the second air inlet groove 36 is opened by different diameters, and the larger the centrifugal force is, the larger the opening of the second air inlet groove 36 is.
