Description

Technical Field

[0001] This invention belongs to the field of water treatment equipment technology, specifically relating to an anti-siphon reverse osmosis device. Background Technology

[0002] Reverse osmosis technology, as the core means of high-purity water treatment, is widely used in many fields such as industrial production, electronics manufacturing, pharmaceuticals, food, and wastewater treatment. Two-stage reverse osmosis, also known as two-stage reverse osmosis, is a process in which the permeate from the first-stage reverse osmosis is adjusted for pH value and then sent to the second-stage reverse osmosis system by a high-pressure pump to obtain the permeate. Reverse osmosis technology is the most advanced and energy-efficient membrane separation technology today. Its principle is that under the action of pressure higher than that of the solution, other substances cannot pass through the semi-permeable membrane, thus separating these substances from water.

[0003] Chinese patent CN121494258A discloses a two-stage reverse osmosis water treatment device, including a shell, an internal guide net, a reverse osmosis membrane inside the guide net, a side plate fixedly connected to the outer side of the guide net, and a spiral plate fixedly connected to the inner wall of the guide net. In the aforementioned application, after long-term use, the packing material in the filter box inside the intermediate treatment unit is prone to clogging due to prolonged unidirectional filtration. The original equipment could only achieve stable processing capacity by manually replacing the packing material filter box or increasing the power of the anti-siphon pressure regulating pump, making the equipment cumbersome to use and increasing maintenance costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an anti-siphon reverse osmosis device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides an anti-siphon reverse osmosis device, comprising a support frame, a pretreatment device fixedly connected to the top left side of the support frame, an inlet on the left side of the pretreatment device, an intermediate treatment device fixedly connected to the top right side of the support frame, a packed filter box movably connected inside the intermediate treatment device, a primary reverse osmosis filter fixedly connected to the rear left end of the support frame, a secondary reverse osmosis filter fixedly connected to the rear right end of the support frame, an anti-siphon pressure regulating pump fixedly connected to the upper side and inside of the support frame, and an outlet at the bottom of the secondary reverse osmosis filter. Each primary reverse osmosis filter has a circular outer shell fixedly connected to its top. A rotating shaft is movably connected inside the circular outer shell. An impeller is fixedly connected to the outer side of the rotating shaft. A motor is fixedly connected to the front end of the left rotating shaft, and a pulley is fixedly connected to the rear end of the left rotating shaft. A pulley is fixedly connected to the rear end of the right rotating shaft. The outer side of pulley is movably connected to pulley two via belt one. A bevel gear is fixedly connected to the rear sides of pulleys one and two. Multiple fixed plates are fixedly connected to the rear side of the support frame. A rotating shaft is movably connected inside each fixed plate. A bevel gear is fixedly connected to the bottom of the rotating shaft, meshing with bevel gear one. A pulley three is fixedly connected to the top of the rotating shaft two. Two rotating shafts three are movably connected inside the intermediate treatment equipment. A pulley four is fixedly connected to the top of each rotating shaft three. The outer side of each pulley three is movably connected to pulley four via belt two. A tilting disc is fixedly connected to the bottom of the rotating shaft three. The system is equipped with a tilting disc and impeller. When the equipment is turned on, the motor is started, causing shaft one to drive the impeller to rotate. This allows the primary filtrate, which has been filtered by the primary reverse osmosis filter, to quickly enter the intermediate treatment equipment, thereby reducing the energy consumption of the bottom anti-siphon pressure regulating pump. At the same time, shaft three drives the tilting disc to rotate, which ensures that the packing material inside the filter box is fully agitated. This prevents the packing material from maintaining unidirectional contact with the primary filtrate for a long time, thus avoiding short-term blockage of the packing material, extending its service life, and reducing maintenance costs.

[0006] Preferably, the height of the tipping disc is less than the height inside the filler filter box, and the thickness of the impeller is the same as the inner thickness of the circular outer shell.

[0007] Preferably, the top and bottom of the filler filter box are provided with filter holes, and the upper and lower sides of the tilting disc do not contact the upper and lower sides of the interior of the filler filter box.

[0008] Preferably, the primary reverse osmosis filter and the secondary reverse osmosis filter are provided with a drain port at the top, a check valve is fixedly connected to the top of the drain port, and an anti-clogging component is fixedly connected to the top of the secondary reverse osmosis filter.

[0009] Preferably, the anti-clogging component includes pulley five, belt three, pulley six, fixed plate two, rotating shaft four, gear one, double-sided planetary gear, fixed circular plate, backflow vent, slider, gear two, rotating pipe, and four-way vent. Pulley five is fixedly connected to the outer side of the rotating shaft two on the right side. Multiple fixed plates two are fixedly connected to the right rear side of the support frame. The rotating shaft four is movably connected inside the fixed plate two. Pulley six is ​​fixedly connected to the outer side of the rotating shaft four. The outer side of pulley five is movably connected to pulley six via belt three. Gear one is fixedly connected to the bottom of the rotating shaft four. The top of the secondary reverse osmosis filter is fixedly connected to a fixed circular plate, and the top of the fixed circular plate is fixedly connected to multiple backflushing air ports. A sliding groove is formed on the outer side of the fixed circular plate, and the outer side of the sliding groove is movably connected to a double-sided planetary gear via a slider. The side of the double-sided planetary gear furthest from its center meshes with gear one. The bottom of the fixed circular plate is movably connected to multiple rotating tubes, and gear two is fixedly connected to the outer side of each rotating tube. Each gear two meshes with the others, and the outermost gear two meshes with the side of the double-sided planetary gear closest to its center. The bottom of the rotating tube is fixedly connected to a four-way air outlet. An anti-clogging component is installed. When the equipment is started, it works in conjunction with gear one, the double-sided planetary gear, and gear two to rotate the rotating tubes, while simultaneously intermittently activating the backflushing air pump. This allows airflow to enter the secondary reverse osmosis filter through the four-way air outlet, thereby preventing clogging of the reverse osmosis membrane, reducing equipment maintenance costs, and making the equipment easier to use.

[0010] Preferably, the secondary reverse osmosis filter has multiple reverse osmosis membranes inside, and the length of the four-way air outlet is less than the distance between each of the reverse osmosis membranes.

[0011] Preferably, a movable joint is fixedly connected to the top of the rotating tube, the interior of the rotating tube is connected to the interior of the backflow vent through the movable joint, a backflow air pump is fixedly connected to the top of the backflow vent, and a pressure regulating pump silent assembly is fixedly connected to the lower side of the support frame.

[0012] Preferably, the pressure regulating pump silencing assembly includes a fixed plate three, a fixed plate four, a shock absorber, a spring, a movable shock absorber plate, a fixed plate five, an arc-shaped silencing plate, and silencing holes. The fixed plate three is fixedly connected to the top of the lower side of the support frame, and the fixed plates four are fixedly connected to the top two sides of the fixed plate three. The shock absorber is fixedly connected inside the fixed plate four, the movable shock absorber plate is fixedly connected to the front end of the shock absorber, the spring is fixedly connected to the outer side of the shock absorber, the fixed plate five is fixedly connected to the rear side of the movable shock absorber plate, and the arc-shaped silencing plate is fixedly connected to the front end of the fixed plate five. The surface of the arc-shaped silencing plate has multiple silencing holes. The pressure regulating pump is equipped with a silent component. When the equipment is running, the anti-siphon pressure regulating pump needs to be started for a long time, which can easily generate a lot of vibration and noise. At this time, the movable damping plates on both sides absorb the shaking generated by the anti-siphon pressure regulating pump, and the kinetic energy of the shaking of the movable damping plates is absorbed by the shock absorber and spring, making the anti-siphon pressure regulating pump run more smoothly and reducing the impact of vibration on the support frame. At the same time, the arc-shaped silent plate reduces the noise generated by the anti-siphon pressure regulating pump, making the anti-siphon pressure regulating pump run more quietly.

[0013] Preferably, the inner surface of the arc-shaped soundproof plate coincides with the center of the cross-section of the rear surface of the anti-siphon pressure regulating pump, and the inner surface of the movable shock-absorbing plate is in contact with the front surface of the anti-siphon pressure regulating pump.

[0014] Preferably, a damping plate is fixedly connected to the inner surface of the movable damping plate, and a thickness-adaptive elastic pad is fixedly connected to the inner surface of the arc-shaped sound-absorbing plate.

[0015] The advantages of this application are: (1) When the equipment is turned on, the motor is started to make the impeller rotate, so that the primary filtrate that has been filtered in the primary reverse osmosis filter can quickly enter the intermediate treatment equipment, thereby reducing the energy consumption of the bottom anti-siphon pressure regulating pump. At the same time, the material turning plate rotates, so that the packing material inside the packing filter box is fully stirred, avoiding the problem of short-term blockage of the packing material by keeping the packing material in one direction in contact with the primary filtrate for a long time, thus extending the service life of the packing material and reducing the operation and maintenance costs.

[0016] (2) When the equipment is started, the rotating tube is rotated by gear one, double planetary gear and gear two. At the same time, the backflush air pump is started intermittently so that the airflow enters the interior of the secondary reverse osmosis filter from the four-way air outlet, thereby avoiding the blockage of the reverse osmosis membrane, reducing equipment maintenance costs and making the equipment more convenient to use.

[0017] (3) When the equipment is running, the anti-siphon pressure regulating pump needs to be started for a long time, which can easily generate a lot of vibration and noise. At this time, the movable damping plates on both sides absorb the shaking generated by the anti-siphon pressure regulating pump, and absorb the kinetic energy of the movable damping plate shaking through the damper and spring, so that the anti-siphon pressure regulating pump runs more smoothly and reduces the impact of vibration on the support frame. At the same time, the arc-shaped silent plate reduces the noise generated by the anti-siphon pressure regulating pump, making the anti-siphon pressure regulating pump run more quietly.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-4 As shown, an anti-siphon reverse osmosis device includes a support frame 100. A pretreatment device 300 is fixedly connected to the top left side of the support frame 100. The pretreatment device 300 removes large particulate impurities from the raw water to prevent damage to the reverse osmosis membrane. An inlet 200 is provided on the left side of the pretreatment device 300. An intermediate treatment device 400 is fixedly connected to the top right side of the support frame 100. The intermediate treatment device 400 allows water to be stored inside and simultaneously adsorbs impurities from the primary filtrate. The intermediate treatment device 400 has internal movable connections. The support frame 100 is equipped with a filler filter box 401. Two primary reverse osmosis filters 500 are fixedly connected to the rear left side of the support frame 100, and a secondary reverse osmosis filter 600 is fixedly connected to the rear right side of the support frame 100. The secondary reverse osmosis filter 600 is set to perform secondary filtration of the primary filtrate, thereby enabling the equipment to achieve a two-stage reverse osmosis filtration process. An anti-siphon pressure regulating pump 700 is fixedly connected to the upper side and inside of the support frame 100. The anti-siphon pressure regulating pump 700 is set to allow the internal pressure of the equipment to be adjusted to prevent sewage backflow. The secondary reverse osmosis filter 600 has an outlet 800 at its bottom. Each primary reverse osmosis filter 500 has a circular outer shell 901 fixedly connected to its top. A rotating shaft 902 is movably connected inside the circular outer shell 901. An impeller 914 is fixedly connected to the outer side of the rotating shaft 902. A motor is fixedly connected to the front end of the left rotating shaft 902, and a pulley 903 is fixedly connected to the rear end of the left rotating shaft 902. A pulley 905 is fixedly connected to the rear end of the right rotating shaft 902. The outer side of pulley 903 is movably connected to pulley 905 via belt 904. Belt 904 is provided so that the power of pulley 903 is transmitted to pulley 905. A bevel gear 906 is fixedly connected to the rear of pulleys 903 and 905. Support frame 1 Multiple fixed plates 909 are fixedly connected to the rear side of the 00. A rotating shaft 908 is movably connected inside each fixed plate 909. A bevel gear 907 is fixedly connected to the bottom of the rotating shaft 908. The bevel gear 907 meshes with the bevel gear 906. A pulley 910 is fixedly connected to the top of the rotating shaft 908. Two rotating shafts 913 are movably connected inside the intermediate processing equipment 400. A pulley 912 is fixedly connected to the top of each rotating shaft 913. The outer side of each pulley 910 is movably connected to the pulley 912 via a belt 911. The belt 911 is set so that the power of the pulley 910 is transmitted to the pulley 912 via the belt 911. A turning plate 915 is fixedly connected to the bottom of the rotating shaft 913.

[0022] The height of the tilting disc 915 is less than the internal height of the packed filter box 401, and the thickness of the impeller 914 is the same as the inner thickness of the circular outer shell 901. Filter holes are provided at the top and bottom of the packed filter box 401, and the upper and lower sides of the tilting disc 915 do not contact the upper and lower sides of the interior of the packed filter box 401.

[0023] The primary reverse osmosis filter 500 and the secondary reverse osmosis filter 600 are provided with a drain port at the top. A check valve is fixedly connected to the top of the drain port. An anti-clogging component 1000 is fixedly connected to the top of the secondary reverse osmosis filter 600.

[0024] The equipment is equipped with a tilting disc 915 and an impeller 914. When the equipment is turned on, the motor is started, causing the first rotating shaft 902 to drive the impeller 914 to rotate. This allows the primary filtrate, which has been filtered by the primary reverse osmosis filter 500, to quickly enter the intermediate treatment equipment 400, thereby reducing the energy consumption of the bottom anti-siphon pressure regulating pump 700. At the same time, the third rotating shaft 913 drives the tilting disc 915 to rotate, thereby fully agitating the packing material inside the packing filter box 401. This prevents the packing material from maintaining unidirectional contact with the primary filtrate for a long time, thus avoiding short-term blockage of the packing material, extending the service life of the packing material, and reducing operation and maintenance costs.

[0025] In practical use, when the above equipment is started, the raw water to be treated is introduced into the inlet 200, allowing it to enter the pretreatment equipment 300 for pretreatment. The anti-siphon pressure regulating pump 700 is then started, allowing the raw water to enter the primary reverse osmosis filter 500 to produce primary filtered water. This primary filtered water then passes through the intermediate treatment equipment 400 and enters the secondary reverse osmosis filter 600 to produce finished water, which is discharged from the outlet 800. Simultaneously, the motor is started, causing the left-side rotating shaft 902 to drive the impeller 914 to rotate, which in turn drives the pulley 903. The pulley 903, via the belt 904, drives the pulley 905 to rotate, causing the right-side rotating shaft 902 to drive the right-side impeller 914 to rotate, thus allowing the primary osmosis filter to... The liquid quickly enters the intermediate treatment equipment 400, thereby reducing the energy consumption of the bottom anti-siphon pressure regulating pump 700. This causes bevel gear 1 906 to rotate, which in turn drives bevel gear 2 907 to rotate. Shaft 2 908 then rotates with bevel gear 2 907, causing pulley 3 910 to rotate. Pulley 3 910, through belt 2 911, drives pulley 4 912 to rotate, which in turn drives shaft 3 913 to rotate. This causes the tilting disc 915 to rotate, thus ensuring that the packing material inside the packing filter box 401 is fully agitated. This prevents the packing material from maintaining unidirectional contact with the primary filtrate for extended periods, which could lead to short-term clogging. This extends the service life of the packing material and reduces maintenance costs.

[0026] Example 2, as Figures 1-6As shown, based on Embodiment 1, the anti-clogging component 1000 includes pulley five 1001, belt three 1002, pulley six 1003, fixing plate two 1004, rotating shaft four 1005, gear one 1006, double-sided planetary gear 1007, fixing circular plate 1008, backflow vent 1009, slider 1010, gear two 1011, rotating tube 1012, four-way vent 1013, and the outer side of the right rotating shaft two 908 is fixedly connected. A pulley 1001 is connected to the support frame 100. Multiple fixing plates 1004 are fixedly connected to the right rear side. A rotating shaft 1005 is movably connected inside the fixing plate 1004. A pulley 1003 is fixedly connected to the outside of the rotating shaft 1005. The outside of pulley 1001 is movably connected to pulley 1003 via belt 1002. Belt 1002 is provided so that the power of pulley 1001 is transmitted to the… The bottom of pulley 6 1003 and shaft 4 1005 is fixedly connected to gear 1 1006. The top of the secondary reverse osmosis filter 600 is fixedly connected to a fixed circular plate 1008. The top of the fixed circular plate 1008 is fixedly connected to multiple backwash vents 1009. The outer side of the fixed circular plate 1008 is provided with a sliding groove. The outer side of the sliding groove is movably connected to a double-sided planetary gear 1007 through a slider 1010. The side of the double-sided planetary gear 1007 away from its center meshes with gear 1 1006. The bottom of the fixed circular plate 1008 is movably connected to multiple rotating tubes 1012. The outer side of the rotating tubes 1012 is fixedly connected to gear 2 1011. Each gear 2 1011 meshes with each other. The outermost gear 2 1011 meshes with the side of the double-sided planetary gear 1007 closest to its center. The bottom of the rotating tubes 1012 is fixedly connected to a four-way air outlet 1013. The four-way air outlet 1013 is provided to make the backwash gas distribution more uniform.

[0027] The secondary reverse osmosis filter 600 has multiple reverse osmosis membranes inside, and the length of the four-way air outlet 1013 is less than the distance between each reverse osmosis membrane.

[0028] A movable joint is fixedly connected to the top of the rotating tube 1012. The interior of the rotating tube 1012 is connected to the interior of the backflow vent 1009 through the movable joint. A backflow air pump is fixedly connected to the top of the backflow vent 1009. A pressure regulating pump silent assembly 1100 is fixedly connected to the lower side of the support frame 100.

[0029] An anti-clogging component 1000 is installed. When the equipment is started, it works with gear 1006, double-sided planetary gear 1007, and gear 2 1011 to rotate the rotating tube 1012. At the same time, the backwash air pump is intermittently activated, allowing airflow to enter the secondary reverse osmosis filter 600 from the four-way air outlet 1013. This prevents the reverse osmosis membrane from clogging, reduces equipment maintenance costs, and makes the equipment easier to use.

[0030] In practical use, when the rotating shaft 2 908 rotates, the pulley 5 1001 rotates along with the right rotating shaft 2 908. The pulley 5 1001 drives the pulley 6 1003 to rotate via the belt 3 1002, causing the rotating shaft 4 1005 to rotate. The gear 1 1006 then rotates along the rotating shaft 4 1005, causing the gear 1 1006 to drive the double-sided planetary gear 1007 to rotate along the slide groove. The double-sided planetary gear 1007 drives multiple gears 2 1011 to rotate, causing the rotating tube 1012 to rotate. At this time, the backflushing air pump is intermittently activated, allowing backflushing gas to enter the rotating tube 1012 from the backflushing air inlet 1009. The backflushing gas is then evenly sprayed from the four-way air outlet 1013 to the inside and outside of the reverse osmosis membrane, thereby preventing the reverse osmosis membrane from becoming clogged, reducing equipment maintenance costs, and making the equipment more convenient to use.

[0031] Example 3, as Figures 1-8 As shown, based on Embodiment 1 or Embodiment 2, the pressure regulating pump silent assembly 1100 includes a fixed plate three 1101, a fixed plate four 1102, a shock absorber 1103, a spring 1104, a movable shock absorber 1105, a fixed plate five 1106, an arc-shaped silent plate 1107, and a silencing hole 1108. The fixed plate three 1101 is fixedly connected to the top of the lower side of the support frame 100, and the fixed plates four 1102 are fixedly connected to the top two sides of the fixed plate three 1101. The shock absorber 1103 is fixedly connected inside the fixed plate four 1102. 1103, so that the vibration of the movable damping plate 1105 is absorbed by the damper 1103. The front end of the damper 1103 is fixedly connected to the movable damping plate 1105, and the outside of the damper 1103 is fixedly connected to the spring 1104. The rear side of the movable damping plate 1105 is fixedly connected to the fixed plate 1106, and the front end of the fixed plate 1106 is fixedly connected to the arc-shaped sound-absorbing plate 1107. The surface of the arc-shaped sound-absorbing plate 1107 is provided with multiple sound-absorbing holes 1108. The sound-absorbing holes 1108 are provided to absorb the operating noise of the anti-siphon pressure regulating pump 700.

[0032] The inner surface of the arc-shaped sound-absorbing plate 1107 coincides with the center of the cross-section of the rear surface of the anti-siphon pressure regulating pump 700, and the inner surface of the movable damping plate 1105 is in contact with the front surface of the anti-siphon pressure regulating pump 700. A vibration damping plate is fixedly connected to the inner surface of the movable damping plate 1105, and a thickness-adaptive elastic pad is fixedly connected to the inner surface of the arc-shaped sound-absorbing plate 1107.

[0033] The pressure regulating pump is equipped with a silent component 1100. When the equipment is running, the anti-siphon pressure regulating pump 700 needs to be started for a long time, which can easily generate a lot of vibration and noise. At this time, the movable damping plates 1105 on both sides absorb the shaking generated by the anti-siphon pressure regulating pump 700, and the kinetic energy of the shaking of the movable damping plates 1105 is absorbed by the shock absorber 1103 and the spring 1104, so that the anti-siphon pressure regulating pump 700 runs more smoothly and reduces the impact of vibration on the support frame 100. At the same time, the arc-shaped silent plate 1107 reduces the noise generated by the anti-siphon pressure regulating pump 700, making the anti-siphon pressure regulating pump 700 run more quietly.

[0034] When the above-mentioned equipment is in use, the anti-siphon pressure regulating pump 700 needs to be started for a long time, which can easily generate a lot of vibration and noise. During installation, the anti-siphon pressure regulating pump 700 is installed on the fixed plate 1101, and the fixed plate 1101 is installed on the support frame 100. At this time, the movable damping plate 1105 is closely attached to both sides of the anti-siphon pressure regulating pump 700, and the arc-shaped sound-absorbing plate 1107 is closely attached to the rear surface of the anti-siphon pressure regulating pump 700. This allows the movable damping plates 1105 on both sides to absorb the vibration generated by the anti-siphon pressure regulating pump 700, and the kinetic energy of the swaying of the movable damping plate 1105 is absorbed by the shock absorber 1103 and the spring 1104. At the same time, the arc-shaped sound-absorbing plate 1107 reduces the noise generated by the anti-siphon pressure regulating pump 700, making the anti-siphon pressure regulating pump 700 run more quietly.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
