Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a terminal high-efficiency equipment for a desalted water system. Background Art

[0002] Desalted water refers to the finished water obtained by removing suspended matter, colloids, inorganic cations, anions and other impurities in water through various water treatment processes. Desalted water does not mean that all salts in the water have been removed. Due to technical reasons and water production cost considerations, desalted water is allowed to contain trace impurities according to different uses. The fewer impurities in the desalted water, the higher the water purity.

[0003] In the prior art, the ultrafiltration device used in desalted water generally uses an ultrafiltration membrane for filtration. However, during ultrafiltration, pollutants in the feed liquid migrate to the membrane surface with the permeate under pressure, and are thereby adsorbed or deposited on the membrane surface, increasing the filtration resistance of the membrane, thereby reducing the filtration efficiency of the filtration membrane. The prior art publication number is CN118791086A, which is an ultrafiltration device for a desalted water system. When the ultrafiltration membrane is severely clogged and the water output begins to change, the ultrafiltration cartridge will rotate, and the two ultrafiltration membranes will interchange positions to perform the water filtration process alternately. However, impurities generated by the filtration are still in the ultrafiltration cartridge. As the filtration process proceeds, the impurities continue to flow with the water flow, which will increase the clogging speed of the filtration membrane, thereby reducing the period of interchange of the two ultrafiltration membranes, which in turn reduces the filtration efficiency of the water. For this reason, the present application proposes a terminal high-efficiency equipment for a desalted water system. Summary of the invention

[0004] The purpose of the present invention is to solve the above technical problems and to propose a high-efficiency terminal equipment for a desalted water system.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0013] Preferably, it also includes a power mechanism for rotating the driving shaft and the first spline cylinder, the power mechanism includes a motor installed at the bottom of the processing cylinder, an incomplete gear is fixed to the output end of the motor, and a first gear and a second gear are respectively fixed to the driving shaft and the first spline cylinder, and the first gear and the second gear can mesh with the incomplete gear.

[0014] Preferably, it also includes a connecting mechanism capable of connecting the first spline cylinder and the second spline cylinder, wherein the connecting mechanism includes a spline shaft located in the first spline cylinder and slidably connected thereto, and the spline shaft is connected to the second spline cylinder to connect the first spline cylinder and the second spline cylinder together.

[0015] Preferably, it also includes a control mechanism capable of driving the spline shaft to move, the control mechanism includes a pressure piston cylinder that passes through the treatment cylinder and is located above the filter membrane, a reset piston is installed in the pressure piston cylinder, a second spring is fixed on the reset piston and the pressure piston cylinder, a lifting piston cylinder is installed on the mounting frame, the lifting piston cylinder is connected to the pressure piston cylinder through a liquid delivery pipe, a lifting piston is slidably connected in the lifting piston cylinder, a connecting plate is fixed on the lifting piston, and the spline shaft is rotatably mounted on the connecting plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The movement of the reset piston can transport the hydraulic oil in the pressure piston cylinder to the lifting piston cylinder through the liquid delivery pipe. The pressure increase in the lifting piston cylinder drives the lifting piston to move upward, thereby driving the spline shaft to move upward. The spline shaft part passes through the first spline cylinder and extends into the second spline cylinder and engages with the second spline cylinder. In this way, the first spline cylinder and the second spline cylinder are connected together for subsequent air supply without the need for a control system and electric drive equipment.

[0018] 2. As the air pressure in the fixed piston cylinder and the movable piston cylinder increases, the positioning piston and the sliding piston can be driven to move, thereby driving the first drive tube and the second drive tube to move, so that the fixed cover and the movable telescopic cover move relative to each other, and finally the fixed cover and the movable telescopic cover are against the stationary rotating disk to achieve the sealing of the filter membrane for recoil processing.

[0019] 3. When the pressure in the mobile piston cylinder is greater than the threshold of the second pressure relief valve, the second pressure relief valve opens, so that the air in the mobile piston cylinder can be transported to the mobile telescopic cover. At this time, the air is discharged in the water in the form of bubbles, and then moves upward through the bottom of the filter membrane. The filter membrane can be backwashed by the backflow of air. With the filtered water in the mobile telescopic cover, the filter membrane can be backwashed and backwashed, and the air and part of the sewage are discharged through the waste liquid pipe.

[0020] 4. The cleaned impurities are located in the fixed cover. When the driving piston moves close to the circular block, the air in the moving piston cylinder can be sucked into the air supply piston cylinder, and part of the air enters the air supply piston cylinder through the air inlet pipe; when the driving piston moves away from the circular block, the moving telescopic cover can be driven up again and against the bottom of the rotating disk. As the moving telescopic cover itself expands and contracts, the filtered water inside can be squeezed and backwashed into the filter membrane and enter the fixed cover. In this way, the filter membrane can be backwashed again, and the filter membrane can be backwashed and backwashed with air. The water in the fixed cover increases, and the dirt generated by the filtration can be discharged through the waste liquid pipe.

[0021] 5. Multiple pulse recoil cleaning of the filter membrane will cause the filter membrane to vibrate, which can effectively clean the filter membrane and improve the cleaning effect of the filter membrane.

[0022] In summary, the present invention can also vibrate the filter membrane by pulse-type backflushing cleaning, greatly improving the effect of cleaning the filter membrane. At the same time, impurities generated by backflushing cleaning can be discharged from the treatment cylinder, avoiding the disadvantage of large accumulation of impurities in the prior art that the filter membrane is quickly blocked.

[0040] It also includes a pumping mechanism capable of delivering air to the fixed piston cylinder 16 and the movable piston cylinder 18, the pumping mechanism includes an air supply piston cylinder 22 installed at the bottom of the processing cylinder 1, a driving piston 31 is slidably connected inside the air supply piston cylinder 22, a mounting frame 9 is installed at the bottom of the processing cylinder 1, a first spline cylinder 44 rotatably connected to the mounting frame 9 is penetrated by the mounting frame 9, the upper end of the first spline cylinder 44 is rotatably connected to the second spline cylinder 12, a gearbox 32 is installed on the mounting frame 9, and the gearbox 32 is a speed reduction box.

[0041] The second spline cylinder 12 is fixedly connected to the bottom of the gearbox 32, and a circular block 34 is fixed to the upper end of the gearbox 32. The upper end of the circular block 34 is eccentrically hingedly connected to a connecting rod 33, and the connecting rod 33 is hingedly connected to the driving piston 31. The air supply piston cylinder 22 is respectively connected to the fixed piston cylinder 16 and the movable piston cylinder 18 through two delivery pipes 10. Short tubes 20 are installed on the two delivery pipes 10, and a solenoid valve 21 is installed on the short tube 20. A first one-way valve 11 is installed on the delivery pipe 10 connected to the fixed piston cylinder 16, and the first one-way valve 11 only allows air to be delivered to the fixed piston cylinder 16 through the delivery pipe 10; an intake pipe 24 is installed on the air supply piston cylinder 22, and a second one-way valve 23 is installed on the intake pipe 24. The second one-way valve 23 only allows air to enter the air supply piston cylinder 22 through the intake pipe 24.

[0042] It also includes a power mechanism for rotating the drive shaft 36 and the first spline cylinder 44. The power mechanism includes a motor 35 installed at the bottom of the processing cylinder 1. An incomplete gear 39 is fixed to the output end of the motor 35. A first gear 37 and a second gear 38 are respectively fixed to the drive shaft 36 and the first spline cylinder 44. The first gear 37 and the second gear 38 can mesh with the incomplete gear 39.

[0043] It also includes a connecting mechanism capable of connecting the first spline cylinder 44 and the second spline cylinder 12. The connecting mechanism includes a spline shaft 43 located in the first spline cylinder 44 and slidably connected thereto. The spline shaft 43 is connected to the second spline cylinder 12 to connect the first spline cylinder 44 and the second spline cylinder 12 together.

[0044] It also includes a control mechanism capable of driving the spline shaft 43 to move, the control mechanism includes a pressure piston cylinder 6 that passes through the processing cylinder 1 and is located above the filter membrane 14, a reset piston 41 is installed in the pressure piston cylinder 6, a second spring 40 is fixed on the reset piston 41 and the pressure piston cylinder 6, a lifting piston cylinder 8 is installed on the mounting frame 9, the lifting piston cylinder 8 is connected to the pressure piston cylinder 6 through a liquid delivery pipe 7, a lifting piston 42 is slidably connected in the lifting piston cylinder 8, a connecting plate is fixed on the lifting piston 42, the spline shaft 43 is rotatably installed on the connecting plate, and the medium transported in the liquid delivery pipe 7 is hydraulic oil.

[0045] When the present invention is used, sewage enters the treatment barrel 1 through the water inlet pipe 4, and the sewage is filtered through the filter membrane 14 and enters the bottom of the rotating disk 13. A drain pipe can be installed at the bottom of the treatment barrel 1 to discharge the filtered water;

[0046] The upper cover 3 is provided with a controller 5, on which a pressure sensor and a control component are installed, and the control component is connected with the pressure sensor, the motor 35, and the solenoid valve 21;

[0047] As the filter membrane 14 filters sewage, impurities accumulate on the surface of the filter membrane 14, resulting in a decrease in the water filtration rate, and the pressure in the treatment cylinder 1 increases due to the continuous inflow of water from the water inlet pipe 4. When the pressure sensor detects that the water pressure reaches the set pressure value, it transmits a signal to the control component, and the control component controls the motor 35 to work;

[0048] Since the treatment cylinder 1 is in a high pressure state, the water pressure drives the reset piston 41 to move. At this time, the second spring 40 is squeezed. The movement of the reset piston 41 can deliver the hydraulic oil in the pressure piston cylinder 6 to the lifting piston cylinder 8 through the liquid delivery pipe 7. The pressure in the lifting piston cylinder 8 increases and drives the lifting piston 42 to move upward, thereby driving the spline shaft 43 to move upward. The spline shaft 43 partially passes through the first spline cylinder 44 and extends into the second spline cylinder 12 and engages with the second spline cylinder 12, so that the first spline cylinder 44 is connected to the second spline cylinder 12 together;

[0049] The motor 35 drives the incomplete gear 39 to rotate, and the rotation of the incomplete gear 39 drives the first gear 37 to rotate. The rotation of the first gear 37 drives the shaft 36, the rotating disk 13 and the filter membrane 14 to rotate. When the incomplete gear 39 is not engaged with the first gear 37, the filter membrane 14 is opposite to the fixed cover 15 and the movable telescopic cover 19. As the incomplete gear 39 rotates, it will engage with the second gear 38. The rotation of the second gear 38 drives the first spline cylinder 44 and the second spline cylinder 12 to rotate, thereby driving the gearbox 32 to rotate, and then drives the circular block 34 to rotate quickly. The rotation of the circular block 34 drives the connecting rod 33 to move, and then drives the driving piston 31 to reciprocate.

[0050] When the driving piston 31 moves close to the circular block 34, the external air can be sucked into the air supply piston cylinder 22 through the air inlet pipe 24. When the driving piston 31 moves away from the circular block 34, the air in the air supply piston cylinder 22 can be squeezed into the two delivery pipes 10, so that it can be delivered to the fixed piston cylinder 16 and the movable piston cylinder 18. As the air pressure in the fixed piston cylinder 16 and the movable piston cylinder 18 increases, the positioning piston 26 and the sliding piston 30 can be driven to move, thereby driving the first driving tube 17 and the second driving tube 29 to move, so that the fixed cover 15 and the movable telescopic cover 19 move relative to each other. Finally, the fixed cover 15 and the movable telescopic cover 19 are against the stationary rotating disk 13 to achieve the sealing of the filter membrane 14. The inside is filled with water, the fixed cover 15 is sewage, and the movable telescopic cover 19 is filtered water, which will not cause blockage to the filter membrane 14 in the reverse direction.

[0051] Among them, Figure 3 As shown, a waste liquid pipe is installed on the fixed cover 15, and the waste liquid pipe runs through the upper cover 3. An electromagnetic control valve is installed on the waste liquid pipe. When the motor 35 is working, the electromagnetic control valve opens, and vice versa.

[0052] As the pressure in the fixed piston cylinder 16 and the movable piston cylinder 18 increases, since the threshold value of the second pressure relief valve 28 is less than the threshold value of the first pressure relief valve 25, when the pressure in the movable piston cylinder 18 is greater than the threshold value of the second pressure relief valve 28, the second pressure relief valve 28 opens, so that the air in the movable piston cylinder 18 can be transported to the movable telescopic cover 19. At this time, the air is discharged in the form of bubbles in the water, and then moves upward through the bottom of the filter membrane 14. The filter membrane 14 can be backwashed by the backflowing air, and the filter membrane 14 can be backwashed and backwashed with the filtered water in the movable telescopic cover 19. The air and part of the sewage are discharged through the waste pipe. Finally, the water level in the fixed cover 15 is lower than the inner top of the fixed cover 15, so only air can be discharged through the waste pipe.

[0053] The cleaned impurities are located in the fixed cover 15. When the driving piston 31 moves close to the circular block 34, the air in the movable piston cylinder 18 can be sucked into the air supply piston cylinder 22, and part of the air enters the air supply piston cylinder 22 through the air inlet pipe 24; when the driving piston 31 moves away from the circular block 34, the movable telescopic cover 19 can be driven to move up again and abut against the bottom of the rotating disk 13. As the movable telescopic cover 19 itself expands and contracts, the filtered water inside can be squeezed and backwashed into the filter membrane 14 and enter the fixed cover 15, so that the filter membrane 14 can be backwashed again, and the filter membrane 14 can be backwashed and backwashed with air;

[0054] At the same time, the water in the fixed cover 15 increases, and the dirt produced by the filtration can be discharged through the waste liquid pipe;

[0055] As mentioned above, the filter membrane 14 is cleaned by multiple pulse backwashing, and the filter membrane 14 is vibrated, which can effectively clean the filter membrane 14, and the generated impurities will be discharged from the treatment cylinder 1, and will not accumulate and affect the filter membrane 14;

[0056] When the incomplete gear 39 is not meshed with the second gear 38, the solenoid valve 21 is opened, and the air is discharged through the short tube 20; under the action of the first spring 27, the fixed cover 15 is reset, and the impact force of the water flow drives the movable telescopic cover 19 to move down and reset, and the second gear 38 remains stationary at this time to facilitate subsequent meshing;

[0057] When the incomplete gear 39 is meshed with the first gear 37, the rotating disk 13 and the filter membrane 14 are driven to rotate again. When the two are not meshed, the above operation is repeated to backwash and clean the filter membrane 14.

[0058] In this way, the filter membranes 14 can be cleaned one by one;

[0059] As the filter membrane 14 is cleaned, its water flow rate increases, so that the pressure in the treatment cylinder 1 decreases. Under the action of the second spring 40, the reset piston 41 is reset, and then the lifting piston 42 is reset, and the spline shaft 43 is separated from the second spline cylinder 12. At this time, the second spline cylinder 12 is not connected to the first spline cylinder 44. Therefore, when the incomplete gear 39 is meshed with the second gear 38, the second spline cylinder 12 is in an idling state and will not clean the filter membrane 14.

[0060] When a cycle ends (such as controlling the working time of the motor 35, half an hour as a cycle, etc.), the motor 35 stops working until the pressure sensor detects the pressure value again and performs cleaning for the next cycle.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
