A rotating cylinder is rotatably installed on the lower surface of the hollow sealed shell 19, and the first rectangular rod 32 is slidably connected to the rotating cylinder. A transverse plate 20 is fixedly connected to the inner wall of one side of the processing box 2, and a fixed cylinder 31 with a T-shaped cross section is connected to the transverse plate 20 through a third torsion spring 33.

[0041] The horizontal plate 20 is provided with an annular opening connected to the first airbag 26, and the fixed cylinder 31 is provided with a plurality of sealed cavities arranged in an annular array, each of which is connected to the annular opening, and a rectangular plate 37 is slidably provided in each sealed cavity, and a T-shaped clamping plate 35 is fixedly connected to one side of the rectangular plate 37, and each T-shaped clamping plate 35 is connected to the inner wall of the corresponding sealed cavity through a first spring 36, and a rotating shaft 17 is rotatably connected to the inner wall of one side of the processing box 2, and a second cam 30 is fixedly connected to the rotating shaft 17, and a second airbag 16 is fixedly connected to the inner wall of one side of the processing box 2, and the sealing plate 13 is connected to the fixed cylinder through a second pull rope 18. 31 connection, in the initial state, the bottom surface of the second rectangular rod 29 is in contact with the lower inner wall of the circular groove, and when the Z-shaped plate 27 moves downward and squeezes the first airbag 26, the through opening is exposed to the outside, and the air in the first airbag 26 is discharged to the inside of each sealed cavity through the annular opening, and the rectangular plate 37 moves inside the sealed cavity, thereby driving the T-shaped clamping plate 35 to move together, and the first spring 36 is deformed at the same time. After multiple T-shaped clamping plates 35 move in the direction close to the second rectangular rod 29, each T-shaped clamping plate 35 will be in contact with the surface of the second rectangular rod 29, and the second rectangular rod 29 can be clamped.

[0042] When the subsequent hydraulic cylinder 12 drives the sealing plate 13 to move up and down, the air is discharged from the multiple exhaust holes 49 to purge the raw water. In the process of the sealing plate 13 moving up and down, under the transmission action of the second pull rope 18, the fixed cylinder 31 and the rotating shaft 17 will be driven to rotate. In the process of the fixed cylinder 31 rotating, under the transmission action of the multiple T-shaped clamps 35, the second rectangular rod 29 rotates at the same time. Under the transmission action of the first rectangular rod 32 and the telescopic rod 38, the circular plate 39 will rotate with the inside of the hollow sealing shell 19, and the multiple unevenly distributed through holes 40 on the circular plate 39 will rotate at the same time. During the rotation of each through hole 40, it will continuously face the exhaust holes 49 at different positions, so that the air is discharged from the exhaust holes 49 at multiple different positions.

[0043] A sealing box 4 is fixedly connected to one side surface of the processing box 2, a vent hole connected to the second airbag 16 is provided in the sealing box 4, an L-shaped tube 24 is fixedly connected in the sealing box 4, a third one-way valve is installed in the L-shaped tube 24 and the vent hole, a T-shaped block 22 is connected to the sealing box 4 through a second spring, a sealing block 23 is connected to the T-shaped block 22 through a third spring, a piston 51 is connected to the T-shaped block 22 through a first return spring, a round opening for connecting the piston 51 is provided on the T-shaped block 22, the piston 51 passes through the round opening, and a vertical rod is fixedly connected to the upper inner wall of the sealing box 4 21. An inner wall of one side of the sealing box 4 is connected with an arc strip 50 through a second return spring. A gravity plate 45 is slidably connected to the L-shaped tube 24. An air guide hole is provided on the gravity plate 45. An arc block 46 is fixedly connected to the upper surface of the gravity plate 45. The arc block 46 is connected to the sealing block 23 through a third pull rope 47. An extrusion rod 48 is fixedly connected to the lower surface of the sealing block 23. The arc surface of the extrusion rod 48 and the arc block 46 fits the surface of one side of the processing box 2 and is fixedly connected with a mounting plate. A pressing block 5 is slidably arranged on the mounting plate. The pressing block 5 is arranged just above the T-shaped block 22.

[0044] The gravity plate 45 has good sealing performance when connected to the L-shaped tube 24. The second cam 30 will squeeze the second airbag 16 many times as the rotating shaft 17 rotates back and forth. After the second airbag 16 is squeezed, the gas inside it can only be discharged into the interior of the sealing box 4 through the outlet, and the sealing block 23 will move up inside the sealing box 4, thereby driving the T-shaped block 22 to move up together. When the T-shaped block 22 moves up to a certain position, the T-shaped block 22 will squeeze the pressing block 5. At this time, the deformation of the second spring reaches the maximum, and the vertical rod 21 will squeeze the piston 51, and the piston 51 and the T-shaped block 22 will slide relative to each other. The piston 51 includes a convex-shaped part. After the piston 51 moves, its thinner part will be inserted into the inside of the circular opening, and there will be a gap between the circular opening on the T-shaped block 22. After the gas in the second airbag 16 continues to be discharged to the interior of the sealing box 4, the sealing block 23 and the T-shaped block 22 will slide relative to each other.

[0045] After the pressing block 5 is squeezed, another water pump will start working, so that the raw water inside the treatment box 2 can be transported from another delivery pipe 7 to the anion exchange shell 3. When the sealing block 23 moves up to a certain position, the third pull rope 47 is in a stretched state. Under the transmission action of the third pull rope 47, the arc block 46 will be driven to move up, and the arc block 46 will squeeze the arc surface of the arc strip 50 to move up. After the gravity plate 45 moves up with the arc block 46, the air guide hole will be arranged face to face with the L-shaped tube 24. At this time, the L-shaped tube 24 is in a conducting state, and the gas inside the sealing box 4 can be discharged through the L-shaped tube 24.

[0046] In the present invention, when in use, raw water is transported to the inside of the cation exchange shell 1 and various cations in the water are removed. Then, under the action of the water pump, the raw water is transported from the cation exchange shell 1 to the inside of the treatment box 2 through the delivery pipe 7. The hydraulic cylinder 12 works at the same time. The raw water will squeeze the rotating plate 15 during the circulation inside the delivery pipe 7. The rotating plate 15 is vertically arranged in the initial state and has good sealing performance when connected to the inner wall of the delivery pipe 7. After being squeezed, the rotating plate 15 will deflect in the direction close to the baffle 14 until the surface of the rotating plate 15 is in contact with the surface of the baffle 14. During the process of the water pump pumping the raw water into the delivery pipe 7, the surface of the rotating plate 15 will be in contact with the surface of the baffle 14 for a long time. The raw water will flow from the gap between the rotating plate 15 and the inner wall of the delivery pipe 7 to the inside of the spray pipe 10 and be sprayed out through multiple spray holes (not shown) at the bottom of the spray pipe 10.

[0047] During the rotation of the rotating plate 15, the rotating block 44 and the conveying tube 7 are driven to rotate relative to each other. Since one end of the first torsion spring 43 is fixedly connected to the rotating block 44 and the other end is fixedly connected to the conveying tube 7, the first torsion spring 43 is deformed. In the initial state, the surface of the bending plate 9 fits the surface of the rotating block 44. During the rotation of the L-shaped rotating block 44, one end thereof moves against the surface of the bending plate 9, thereby causing the bending plate 9 to move upward, and the fixed plate 42 moves upward at the same time. The fixed plate 42 has a good sealing performance when connected to the shunt tube 6. After the fixed plate 42 moves upward, the circular hole 41 moves to the inside of the shunt tube 6. At this time, the shunt tube 6 is in a conducting state. In the initial state, the first cam 25 is The first cam 25 is arranged to be inclined, and the surface of the first cam 25 is in contact with the surface of the Z-shaped plate 27. At this time, the Z-shaped plate 27 is not in contact with the lower surface of the hollow sealing shell 19, and squeezes the first airbag 26. Since one end of the first pull rope 8 is fixedly connected to the bending plate 9, and the other end is wrapped around the rotating rod 11 and cannot be detached from the rotating rod 11, and the two ends of the second torsion spring are respectively fixedly connected to the processing box 2 and the rotating rod 11. During the upward movement of the bending plate 9, under the transmission action of the first pull rope 8, the rotating rod 11 and the processing box 2 rotate relative to each other. During the rotation of the first cam 25, it will move up against the surface of the Z-shaped plate 27 until the surface of the Z-shaped plate 27 is in contact with the lower surface of the hollow sealing shell 19, that is, the through hole is completely sealed and blocked.

[0048] During the process of the hydraulic cylinder 12 driving the sealing plate 13 to move up and down inside the processing box 2, since the first one-way valve restricts the inside of the processing box 2, the air below the hollow sealing shell 19 can only be discharged from the air outlet and enter from the air inlet, and at this time the Z-shaped plate 27 blocks the opening, and the air cannot flow into the interior of the hollow sealing shell 19. During the upward movement of the sealing plate 13, the air inside the processing box 2 can only be transported to the internal space of the upper part of the processing box 2 through the diverter pipe 6. The gas ejection direction is perpendicular to the raw water ejected from the spray hole. After the gas is blown out, the raw water can be purged to remove the free carbon dioxide gas in the raw water. The carbon dioxide stripping effect is better, and the carbon dioxide can be discharged from the processing box 2 through the exhaust pipe, which effectively avoids the corrosion of carbon dioxide to the device, improves the service life of the device, and is beneficial to the use of the device.

[0049] When the raw water is completely discharged into the processing box 2 through the delivery pipe 7, there is no squeezing effect of the raw water. Under the rebound effect of the first torsion spring 43, the rotating plate 15 will rotate to the vertical state again, and the bending plate 9 will also move down to the initial position under the action of gravity and fit with the surface of the rotating block 44. After the fixed plate 42 moves down, the circular hole 41 will move to the outside of the delivery pipe 7. At this time, the shunt pipe 6 is in a non-conducting state. Under the transmission effect of the first pull rope 8, the rotating rod 11 will rotate under the elastic force of the second torsion spring. After the first cam 25 rotates, it will be moved from the vertical position to the horizontal position. The straight state becomes an inclined state again, and the Z-shaped plate 27 will move vertically downward under the action of gravity and squeeze the first airbag 26. The opening is exposed on the outside, and the air in the first airbag 26 will be discharged to the inside of each sealed cavity through the annular opening. Each rectangular plate 37 has good sealing when connected to the inner wall of the sealed cavity. The rectangular plate 37 will move inside the sealed cavity, thereby driving the T-shaped clamp plate 35 to move together. Since one end of each first spring 36 is fixedly connected to the T-shaped clamp plate 35, and the other end is fixedly connected to the inner wall of the sealed cavity, the first spring 36 is deformed at the same time.

[0050] After the multiple T-shaped clamps 35 move toward the direction close to the second rectangular rod 29, the rubber surface of each T-shaped clamp 35 will be in close contact with the surface of the second rectangular rod 29, so that the second rectangular rod 29 can be clamped. When the hydraulic cylinder 12 drives the sealing plate 13 to move up and down, the air in the lower part of the processing box 2 will only enter the interior of the hollow sealing shell 19 from the opening and be discharged from each exhaust hole 49. The second one-way valve can effectively prevent the air from entering the interior of the hollow sealing shell 19 from the exhaust hole 49. After the air is discharged from the multiple exhaust holes 49, the raw water can be purged. In order to better remove the carbon dioxide gas free in the water, one end of the second pull rope 18 is fixedly connected to the sealing plate 13, and the other end is wrapped around the fixed cylinder 31 and cannot be separated from the fixed cylinder 31, and the surface of the second pull rope 18 is in contact with the surface of the rotating shaft 17. During the up and down movement of the sealing plate 13, the fixed cylinder 31 and the rotating shaft 17 are driven to rotate under the transmission action of the second pull rope 18. Since one end of the third torsion spring 33 is fixedly connected to the fixed cylinder 31, and the other end is fixedly connected to the cross plate 20, the third torsion spring 33 is deformed.

[0051] During the rotation of the fixed cylinder 31, under the transmission action of multiple T-shaped clamps 35, the second rectangular rod 29 rotates at the same time, and under the transmission action of the first rectangular rod 32 and the telescopic rod 38, the circular plate 39 will rotate with the inside of the hollow sealing shell 19, and multiple unevenly distributed through holes 40 on the circular plate 39 will rotate at the same time. During the rotation of each through hole 40, it will continuously face the exhaust holes 49 at different positions, so that air is discharged from the exhaust holes 49 at multiple different positions, so that the air can be more evenly transported to the inside of the raw water, so as to better and more thoroughly remove the free carbon dioxide gas in the water.

[0052] When the rotating shaft 17 rotates back and forth, the second cam 30 will be driven to rotate back and forth together. When the second cam 30 rotates back and forth, the second airbag 16 will be squeezed many times. The outlet and inlet of the second airbag 16 are both provided with a fourth one-way valve, and the inlet is connected to the atmosphere. After the second airbag 16 is squeezed, the gas inside it can only be discharged into the interior of the sealing box 4 through the outlet. The sealing block 23 has good sealing performance when connected to the inner wall of the sealing box 4, and the sealing block 23 has good sealing performance with the T-shaped block 22. An empty port is provided on the T-shaped block 22, and a one-way valve is provided in the empty port. Only outside air can enter the sealing box through the empty port. The sealing block 23 and the T-block 22 are between each other, and the sealing block 23 will move up inside the sealing box 4, thereby driving the T-block 22 to move up together. Since the two ends of the second spring are respectively fixedly connected to the sealing box 4 and the T-block 22, the second spring is deformed. When the T-block 22 moves up to a certain position, the T-block 22 will squeeze the pressing block 5. At this time, the deformation of the second spring reaches the maximum, and the vertical rod 21 will squeeze the piston 51, and the piston 51 and the T-block 22 slide relative to each other. Since the two ends of the first return spring (not shown) are respectively fixedly connected to the piston 51 and the T-block 22, the first return spring is deformed.

[0053] The piston 51 includes a convex portion, and in the initial state, the thicker portion of the piston 51 is inserted into the round opening (such as the attached Figure 8 As shown), the round opening on the T-shaped block 22 is sealed and blocked. After the piston 51 moves, its thinner part will be inserted into the round opening, and there will be a gap between the round opening. After the gas in the second airbag 16 continues to be discharged into the interior of the sealing box 4, the sealing block 23 will slide relative to the T-shaped block 22. Since the two ends of the third spring are fixedly connected to the sealing block 23 and the T-shaped block 22 respectively, the third spring is deformed at the same time, and the air between the T-shaped block 22 and the sealing block 23 can only be discharged through the round opening. After the pressing block 5 is squeezed, another water pump will start working, so that the raw water inside the treatment box 2 can be transported from another delivery pipe 7 to the anion exchange housing 3. When the sealing block 23 moves up, the raw water inside the treatment box 2 can be transported to the anion exchange housing 3. After reaching a certain position, the third pull rope 47 is in a stretched state. Since the two ends of the third pull rope 47 are fixedly connected to the arc block 46 and the sealing block 23 respectively, the arc block 46 will be driven to move upward under the transmission action of the third pull rope 47, and the arc block 46 will squeeze the arc surface of the arc bar 50 to move upward, and the arc bar 50 will slide relative to the sealing box 4. Since the two ends of the second return spring (not shown) are fixedly connected to the sealing box 4 and the arc bar 50 respectively, the second return spring is deformed, and the gravity plate 45 moves up with the arc block 46, and the air guide hole will face the L-shaped tube 24. At this time, the L-shaped tube 24 is in a conductive state, and the gas inside the sealing box 4 can be discharged through the L-shaped tube 24.
