Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis, and in particular to a reverse osmosis device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of using various technologies and means to separate, remove, recycle or convert pollutants contained in sewage into harmless substances so that sewage can meet the water quality requirements for discharge into a water body or reuse. This process includes a variety of methods such as physical, chemical and biological treatment, aiming to purify water quality, protect the environment and human health. In the sewage treatment process, reverse osmosis has been proven to be the most effective method for removing salt, chemical pollutants and heavy metals compared with other traditional water treatment processes.

[0003] Reverse osmosis is a membrane separation operation driven by pressure difference. Its working principle is to make the solvent flow in the opposite direction of natural osmosis by applying pressure. When pressure is applied to the liquid on one side of the membrane, when the pressure exceeds its osmotic pressure, the solvent will reversely permeate in the opposite direction of natural osmosis, so that the permeated solvent, i.e., the permeate, is obtained on the low-pressure side of the membrane; and the concentrated solution, i.e., the concentrate, is obtained on the high-pressure side.

[0004] In the existing reverse osmosis filtration water purification equipment, if the reverse osmosis membrane is used for a long time, gel layer impurities will be formed on the surface of the filter membrane, which will reduce the water permeability of the membrane and affect the treatment effect. In the reverse osmosis membrane treatment, backwashing and filter membrane removal and cleaning are usually adopted. In the existing reverse osmosis membrane operation, the water purification amount of the reverse osmosis membrane is different, and it is difficult to dismantle and clean the reverse osmosis membranes in different positions. Therefore, all reverse osmosis membranes need to be shut down for dismantling and cleaning, which increases the operation time and reduces the treatment efficiency. At the same time, during the continuous cleaning process of the reverse osmosis membrane, it is easy to cause the cleaning liquid to be difficult to fully circulate in certain areas, so that these areas cannot be effectively cleaned, and continuous cleaning is prone to excessive mechanical stress, which damages the service life of the reverse osmosis membrane. At the same time, it is difficult for the cleaning liquid and impurity liquid to be diverted and discharged, resulting in low cleaning efficiency, and the mixed discharge of the cleaning liquid and the waste liquid causes unnecessary waste and increases the treatment cost. Therefore, the present application provides a reverse osmosis equipment for sewage treatment to meet the needs. Summary of the invention

[0043] As an implementation method in this embodiment, Figures 4 to 6As shown, the connection adjustment component 6 includes a fixed seat 61, the fixed seat 61 is installed on the top of the mobile platform 1, a telescopic tube 62 is installed on the top of the fixed seat 61, a support rod 63 is installed at one end of the telescopic tube 62, a membrane support base 64 is installed on one side of the support rod 63, a sleeve 65 is sleeved on the surface of the reverse osmosis membrane 12, a slider 66 is installed on the surface of the sleeve 65, a stretching rod 67 is installed on the top of the slider 66, a gap block 68 is installed at the bottom of the stretching rod 67, a gas rod 69 is installed on the top of the gap block 68, and a connecting end pipe 610 is installed at one end of the reverse osmosis membrane 12. When the staff adjusts the rising height installed on the fixed seat 61 to the bottom of the reverse osmosis membrane 12 installed on the membrane frame 11 through the control center 2, it stops and then moves the mobile platform 1. When the membrane support base 64 moves to the bottom of the reverse osmosis membrane 12, the telescopic tube 62 drives the support base 64 at one end of the support rod 63. The membrane base 64 continues to rise, and then moves to the top of the mobile platform 1, and connects one end of the reverse osmosis membrane 12 to the connecting end tube 610. When the connecting end tube 610 is squeezed, it moves backwards first by elastic action, and then when the reverse osmosis membrane 12 continues to descend, the connecting end tube 610 elastically clings to the inner wall of the reverse osmosis membrane 12, and then the slider 66 on the sleeve 65 is moved, so that the slider 66 drives the stretching rod 67 to move toward one end. When the stretching rod 67 moves, the gap block 68 installed at the bottom of the stretching rod 67 moves together. When the gap block 68 moves the gap between the connecting end tube 610 and the reverse osmosis membrane 12, the gas rod 69 at the top of the gap block 68 starts to run, driving the gap block 68 to cling to the gap between the connecting end tube 610 and the reverse osmosis membrane 12 to play a role in reinforcing the seal. At this time, the connecting end tube 610 and the reverse osmosis membrane 12 are sealed and connected to each other.

[0044] As an implementation method in this embodiment, Figures 4 to 9As shown, the intermittent liquid filling component 7 includes a piston chamber 71, which is mounted on the top of the driving rod 15, a guide seat 72 is mounted at one end of the piston chamber 71, a guide pipe 73 is mounted inside the guide seat 72, a liquid collecting bin 74 is mounted at the bottom of the guide pipe 73, a liquid discharge pipe 710 is mounted on one side of the liquid collecting bin 74, a turntable 75 is mounted on the top of the driving rod 15, a rotating shaft 76 is mounted at one end of the turntable 75, a folding connecting rod 77 is rotatably connected to one end of the rotating shaft 76, a piston block 78 is mounted at one end of the folding connecting rod 77, and a liquid infusion tube 79 is mounted at one end of the guide seat 72. When the intermittent liquid filling component 7 is running, the servo motor 13 drives the driving rod 15 on the mounting seat 14 to rotate intermittently clockwise and counterclockwise. When the driving rod 15 rotates, the turntable 75 mounted on the top of the driving rod 15 drives the rotating shaft 76 to move. When the rotating shaft 76 moves, the rotating shaft 76 drives the folding connecting rod 77 installed at one end to move together. When the folding connecting rod 77 moves, the piston block 78 installed at one end of the folding connecting rod 77 starts to move. At this time, the piston block 78 performs piston movement inside the piston chamber 71. When the piston block 78 moves toward the turntable 75, the cleaning liquid in the cleaning solution tank 3 is transported to the piston chamber 71 through the one-way valve 4. According to the accumulation of impurities inside the reverse osmosis membrane 12, the size of the opening of the valve 5 for transporting the cleaning liquid is reasonably adjusted. At the same time, when the piston block 78 moves toward the guide seat 72, the cleaning liquid will be squeezed into the infusion pipe 79, and then transported to the guide pipe 73 through the guide seat 72, and then transported to the reverse osmosis membrane 12 through the guide pipe 73 to remove the impurities in the gel layer on the reverse osmosis membrane 12. When the cleaning liquid stops being transported, the waste liquid together with the gel impurities in the reverse osmosis membrane 12 is discharged to the liquid collecting bin 74 through the guide pipe 73, and the waste liquid in the liquid collecting bin 74 is discharged to the waste liquid purification device through the discharge pipe 710 through reasonable planning.

[0045] As an implementation method in this embodiment, Figures 7 to 12As shown, the shunt regulating assembly 8 includes a rotating sleeve 81, which is mounted on the surface of the driving rod 15, and a rotating tooth 82 is mounted inside the rotating sleeve 81, one end of the rotating tooth 82 is meshedly connected with a rack 83, one end of the rack 83 is meshedly connected with a gear 84, the surface of the gear 84 is sleeved with a box tube 811, a first connecting rod 85 is mounted on the top of the gear 84, a first sphere 86 is mounted on the top of the first connecting rod 85, and the first sphere 86 is arranged inside the infusion tube 79, a relative bevel gear 87 is mounted on the surface of the first connecting rod 85, one end of the relative bevel gear 87 is meshedly connected with a helical gear set 88, one end of the helical gear set 88 is mounted with a second connecting rod 89, and one end of the second connecting rod 89 is A second sphere 810 is installed at the end, and the second sphere 810 is arranged inside the guide tube 73. When the piston block 78 operates in the piston chamber 71, the driving rod 15 drives the shunt regulating assembly 8 to start running at the same time. When the shunt regulating assembly 8 is running, the rotating tooth 82 in the rotating sleeve 81 drives the rack 83 meshing at one end to move. When the rack 83 moves, the gear 84 meshing at the other end of the rack 83 starts to rotate in the box barrel 811. When the box barrel 811 rotates, the first connecting rod 85 installed on the top of the gear 84 rotates. When the first connecting rod 85 rotates, the first sphere 86 installed on the top of the first connecting rod 85 also rotates. When When the piston block 78 moves toward the turntable 75, the first sphere 86 flips over and closes the inside of the infusion tube 79. At this time, the cleaning liquid is sucked into the piston cavity 71. When the piston block 78 moves toward the guide seat 72, the first sphere 86 opens. At this time, the cleaning liquid flows into the guide tube 73 through the infusion tube 79 and is transported to the reverse osmosis membrane 12. At the same time, when the first connecting rod 85 rotates, the relative bevel gear 87 installed on the surface of the first connecting rod 85 is driven to rotate. When the relative bevel gear 87 rotates, the bevel gear set 88 meshing with one end of the relative bevel gear 87 starts to rotate. When the bevel gear set 88 rotates, the second connecting rod 89 installed at one end of the bevel gear set 88 drives the second connecting rod 89 to rotate. The second sphere 810 installed at the end rotates. Due to the series connection condition between the first sphere 86 and the second sphere 810, when the first sphere 86 opens the channel of the infusion tube 79, the second sphere 810 at another place closes the internal channel of the guide tube 73, thereby realizing an open-close and a close-open state. When the cleaning liquid is transported to the infusion tube 79, the guide tube 73 is in a closed state, ensuring that the cleaning liquid can be transported to the inside of the reverse osmosis membrane 12. When the guide tube 73 is in an open state, the gel impurity waste liquid flows into the liquid collecting bin 74. At this time, the infusion tube 79 is in a closed state, and the piston chamber 71 replenishes the cleaning liquid from the cleaning solution tank 3, realizing an intermittent reciprocating liquid filling state.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When using the device, first check the integrity of each device on the mobile platform 1, then check the cleaning pump 9 and the pressure tank 10, then move the mobile platform 1 to one side of the membrane rack 11, and then check the operating status of each electrical component through the control center 2, and then start operating the equipment.

[0048] After the mobile platform 1 is moved to one side of the membrane frame 11, the connection adjustment component 6 starts to operate, and then the staff adjusts the rising height installed on the fixed seat 61 to the bottom of the reverse osmosis membrane 12 installed on the membrane frame 11 through the control center 2 and stops, and then moves the mobile platform 1. When the membrane support base 64 moves to the bottom of the reverse osmosis membrane 12, the telescopic tube 62 drives the membrane support base 64 at one end of the support rod 63 to continue to rise, and then moves to the top of the mobile platform 1, and connects one end of the reverse osmosis membrane 12 to the connecting end pipe 610. When the connecting end pipe 610 is squeezed, the elastic effect first moves backward, and then when the reverse osmosis membrane 12 During the continued descent, the connecting end tube 610 is elastically pressed against the inner wall of the reverse osmosis membrane 12, and then the slider 66 on the sleeve 65 is moved, so that the slider 66 drives the stretching rod 67 to move toward one end. When the stretching rod 67 moves, the gap block 68 installed at the bottom of the stretching rod 67 moves together. When the gap block 68 moves the gap between the connecting end tube 610 and the reverse osmosis membrane 12, the gas rod 69 at the top of the gap block 68 starts to run, driving the gap block 68 to press against the gap between the connecting end tube 610 and the reverse osmosis membrane 12 to play a role in reinforcing the seal. At this time, the connecting end tube 610 and the reverse osmosis membrane 12 are sealed and connected to each other.

[0049] After the connecting end tube 610 is sealed and connected to the reverse osmosis membrane 12, the intermittent liquid filling component 7 starts to operate. When the intermittent liquid filling component 7 is operating, the servo motor 13 drives the driving rod 15 on the mounting seat 14 to rotate intermittently clockwise and counterclockwise. When the driving rod 15 rotates, the turntable 75 installed on the top of the driving rod 15 drives the rotating shaft 76 to move. When the rotating shaft 76 moves, the rotating shaft 76 drives the folding connecting rod 77 installed at one end to move together. When the folding connecting rod 77 moves, the piston block 78 installed at one end of the folding connecting rod 77 starts to move. At this time, the piston block 78 performs piston motion inside the piston chamber 71. When the piston block 78 moves toward the turntable 75, the cleaning solution tank 3 The cleaning liquid inside is delivered to the piston chamber 71 through the one-way valve 4. According to the accumulation of impurities inside the reverse osmosis membrane 12, the size of the opening of the valve 5 for delivering the cleaning liquid is reasonably adjusted. At the same time, when the piston block 78 moves toward the guide seat 72, the cleaning liquid will be squeezed into the infusion tube 79, and then delivered to the guide pipe 73 through the guide seat 72, and then delivered to the reverse osmosis membrane 12 through the guide pipe 73 to remove the impurities in the gel layer on the reverse osmosis membrane 12. When the cleaning liquid stops being delivered, the waste liquid together with the gel impurities in the reverse osmosis membrane 12 is discharged to the liquid collecting bin 74 through the guide pipe 73, and the waste liquid in the liquid collecting bin 74 is discharged to the waste liquid purification device through the discharge pipe 710 through reasonable planning.

[0050] When the piston block 78 operates in the piston chamber 71, the driving rod 15 simultaneously drives the shunt regulating assembly 8 to start operating. When the shunt regulating assembly 8 is operating, the rotating gear 82 in the rotating sleeve 81 drives the rack 83 meshing at one end to move. When the rack 83 moves, the gear 84 meshing at the other end of the rack 83 starts to rotate in the box barrel 811. When the box barrel 811 rotates, the first connecting rod 85 installed on the top of the gear 84 rotates. When the first connecting rod 85 rotates, the first sphere 86 installed on the top of the first connecting rod 85 also rotates. Then, when the piston block 78 moves toward the rotating disk 75, the first sphere 86 flips over and closes the inside of the infusion tube 79. At this time, the cleaning liquid is sucked into the piston chamber 71. When the piston block 78 moves toward the guide seat 72, the first sphere 86 opens. At this time, the cleaning liquid flows into the guide tube 73 through the infusion tube 79 and is transported to the reverse osmosis membrane 12. At the same time, when the first connecting rod 85 rotates, it drives the first The relative bevel gear 87 installed on the surface of the connecting rod 85 rotates. When the relative bevel gear 87 rotates, the bevel gear set 88 meshingly connected at one end of the relative bevel gear 87 starts to rotate. When the bevel gear set 88 rotates, the second connecting rod 89 installed at one end of the bevel gear set 88 drives the second ball 810 installed at one end of the second connecting rod 89 to rotate. Due to the series connection condition of the first ball 86 and the second ball 810, when the first ball 86 opens the channel of the infusion tube 79, the second ball 810 at another place closes the internal channel of the guide tube 73, thereby realizing an open-close and a close-open state. When the cleaning liquid is transported to the infusion tube 79, the guide tube 73 is in a closed state to ensure that the cleaning liquid can be transported to the inside of the reverse osmosis membrane 12. When the guide tube 73 is in an open state, the gel impurity waste liquid flows into the liquid collecting bin 74. At this time, the infusion tube 79 is in a closed state, and the piston chamber 71 replenishes the cleaning liquid from the cleaning solution tank 3 to achieve an intermittent reciprocating liquid filling state.
