Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis equipment, and in particular to a high-efficiency reverse osmosis device. Background Art

[0002] Reverse osmosis technology is the most advanced and energy-efficient separation technology and a water treatment process. Reverse osmosis technology has the advantages of low energy consumption, no pollution, advanced technology, simple operation and maintenance, etc. It is used in the fields of seawater and brackish water desalination, pure water preparation, and concentration and recovery of chemical products. The principle is to separate the solute from the solvent in the solution under the action of pressure higher than the osmotic pressure of the solution by means of the selective interception of the semipermeable membrane that only allows water to pass through but not other substances. By utilizing the separation characteristics of the reverse osmosis membrane, impurities such as dissolved salts, colloids, organic matter, bacteria, and microorganisms in the water can be effectively removed.

[0003] In order to ensure that there is no scaling on the surface of the membrane element, ensure the long-term operation effect of the membrane and extend the service life of the membrane, an antiscalant dosing device needs to be installed in front of the reverse osmosis device.

[0004] The Chinese patent with the authorization announcement number CN116199349B discloses an adaptive dosing device for scale inhibitors, which solves the problem that passive controlled dosing and intermittent controllable dosing of multiple components cannot be achieved during the addition of scale inhibitors in non-circulating conveying pipelines. This patent can use bypass flow medium to achieve self-driven dosing, which can be adapted to the scenario of passive dosing. At the same time, the dosing method of this scheme is periodic intermittent dosing, and its periodic frequency is adjusted and set by incomplete gear distribution and bypass flow, which can be applied to intermittent dosing in non-circulating conveying pipelines. The dosing process interval is controllable. Under the condition of meeting the above working conditions, this scheme can also achieve multi-component simultaneous or intermittent dosing, and can also be used in conjunction with the existing dosing system, with strong scalability.

[0005] Depending on the water quality, it is necessary to prepare antiscalant solutions of different dilutions. The dilution of the antiscalant directly affects the use effect and system performance of the antiscalant. The prepared antiscalant takes a certain amount of time to be used up, but affected by temperature or other environmental factors, the antiscalant will be stratified. The concentration of antiscalant at different depths is different. When the antiscalant needs to be extracted, it is too late to stir and mix it, which will cause some of the antiscalant that does not meet the standards to be extracted and sent to the reverse osmosis device, affecting the use effect. Summary of the invention

[0006] The present invention provides a high-efficiency reverse osmosis device, aiming to solve the problem in the related art that according to different water qualities, it is necessary to prepare antiscalant solutions of different dilutions, the dilution of the antiscalant directly affects the use effect and system performance of the antiscalant, and the prepared antiscalant takes a certain amount of time to be used up, but affected by temperature or other environmental factors, the antiscalant will be stratified, and the concentrations of the antiscalants at different depths are different. When it is necessary to extract the antiscalant, it is too late to stir and mix it, which will cause a part of the antiscalant that does not meet the standards to be extracted and sent to the reverse osmosis device, thus affecting the technical problem of the use effect.

[0007] The invention discloses a high-efficiency reverse osmosis device, comprising: a reverse osmosis system, a cylinder and a metering pump, wherein a mixing module, a connecting pipe and a liquid taking module are arranged in the cylinder; the mixing module comprises a mixing chamber arranged in the cylinder and connected with the metering pump, the mixing chamber has a liquid inlet, and an impeller is rotatably installed at the liquid inlet, a stirring blade which cooperates with the impeller transmission is also rotatably installed in the mixing chamber, the connecting pipe is vertically fixed to the mixing chamber, and the connecting pipe is connected with the mixing chamber through the liquid inlet; the liquid taking module comprises two liquid suction discs distributed up and down, the lower liquid suction disc is fixedly arranged at the bottom of the cylinder, and the upper liquid suction disc is fixedly arranged on the There is a floating plate and axially slides with the connecting tube. The suction plate and the connecting tube are coaxially arranged with the cylinder body. Concentration detection parts are fixed on the two suction plates. The suction plates are provided with suction units and adjustment units. The suction unit includes a liquid collection cavity arranged on the suction plate, and multiple liquid inlet channels circumferentially arranged on the side walls of the suction plate and connected with the liquid collection cavity. The liquid collection cavities of the two suction plates are connected with the bottom of the connecting tube through pipelines. The adjustment unit includes an adjustment plug that slides vertically in the liquid inlet channel. The adjustment plug has an adjustment hole to control the flux of the liquid inlet channel. The adjustment plug is provided with a driving component to drive it to slide.

[0008] As the scale inhibitor is used, the floating plate will also gradually descend with the liquid level with the upper suction plate. The concentration detection parts on the upper and lower suction plates detect the concentration of the upper and bottom scale inhibitors in real time. After precise calculation by the control panel, the flux of the liquid inlet channels on the upper and lower suction plates is adjusted simultaneously through the adjusting plug, so that the upper and lower suction plates extract a certain proportion of the upper and bottom scale inhibitors respectively, and the extracted scale inhibitors enter the mixing chamber from the connecting pipe together. When the scale inhibitor enters the mixing chamber from the liquid inlet through the connecting pipe, it can drive the impeller to rotate, and the impeller drives the stirring blade to rotate. The stirring blade can stir and mix the scale inhibitor entering the mixing chamber. The concentration after mixing can meet the addition standard. The mixed scale inhibitor is pumped into the reverse osmosis system through the metering pump. After the scale inhibitor is allowed to stand and stratify, the scale inhibitor of appropriate concentration can still be extracted and pumped into the reverse osmosis system, ensuring the use effect of the scale inhibitor.

[0009] Preferably, gears are provided on the rotating shafts of the stirring blade and the impeller, and the two gears are meshed.

[0012] The upper liquid suction plate and the lower liquid suction plate are located at different heights. This arrangement can ensure that the suction force between the connecting pipe and the upper liquid suction plate and the lower liquid suction plate is the same, avoiding interference.

[0013] Preferably, the driving assembly includes a driving member installed in the annular cavity, a telescopic portion of the driving member is fixedly mounted with a fixing ring, and the fixing ring is fixedly connected to all the adjusting plugs.

[0014] Preferably, a slide groove is provided on the outer side wall of the connecting tube along its axial direction, and a sliding block matching the slide groove is provided on the upper liquid suction plate so that the upper liquid suction plate can slide along the connecting tube.

[0015] Preferably, a spiral groove is provided on the outer peripheral wall of the connecting pipe near the lower end, and the upper end of the spiral groove is connected to the slide groove so that the upper liquid suction plate can rotate when descending along the spiral groove.

During the rotation of the scraper, the scale inhibitor remaining at the bottom of the cylinder will be scraped to the lower suction plate, and finally sucked away by the liquid inlet channel on the lower suction plate, completing the cleaning of the scale inhibitor remaining at the bottom of the cylinder.

[0018] Preferably, the adjustment hole is a triangular structure.

[0019] This enables the regulating plug to more sensitively control the flux size of the liquid inlet channel.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows: As the scale inhibitor is used, the floating plate will also gradually descend with the liquid level with the upper suction plate. The concentration detection parts on the upper and lower suction plates detect the concentration of the upper and bottom scale inhibitors in real time. After precise calculation by the control panel, the flux of the liquid inlet channels on the upper and lower suction plates is adjusted simultaneously through the adjusting plug, so that the upper and lower suction plates extract a certain proportion of the upper and bottom scale inhibitors respectively, and the extracted scale inhibitors enter the mixing chamber from the connecting pipe together. When the scale inhibitor enters the mixing chamber from the liquid inlet through the connecting pipe, it can drive the impeller to rotate, and the impeller drives the stirring blade to rotate. The stirring blade can stir and mix the scale inhibitor entering the mixing chamber. The concentration after mixing can meet the addition standard. The mixed scale inhibitor is pumped into the reverse osmosis system through the metering pump. After the scale inhibitor is allowed to stand and stratify, the scale inhibitor of appropriate concentration can still be extracted and pumped into the reverse osmosis system, ensuring the use effect of the scale inhibitor.

[0021] When the upper suction plate rotates while descending along the spiral groove, the floating plate will drive the scraper to rotate, and the mounting ear will continue to slide down along the slide rod. During the rotation of the scraper, the scale inhibitor remaining at the bottom of the cylinder will be scraped to the lower suction plate, and finally sucked away by the liquid inlet channel on the lower suction plate, completing the cleaning of the scale inhibitor remaining at the bottom of the cylinder.

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 8 As shown, a specific embodiment of a high-efficiency reverse osmosis device of the present invention includes a reverse osmosis system 10, a cylinder 20, a liquid extraction module, a mixing module, a carrying module, a liquid extraction module and a scraping module.

[0033] The cylinder 20 is fixedly mounted on the base of the reverse osmosis system 10 . A liquid adding port is provided on the cylinder 20 for adding the antiscalant with a prepared dilution degree into the cylinder 20 .

[0034] like Figure 1 and Figure 2 As shown, the liquid extraction module includes a metering pump 21 fixedly mounted on the upper surface of the cylinder 20, the liquid extraction end of the metering pump 21 is connected to a liquid extraction pipe 23 for extracting the scale inhibitor in the cylinder 20, the liquid outlet end of the metering pump 21 is connected to a liquid outlet pipe 22, and the other end of the liquid outlet pipe 22 is connected to a liquid delivery pipeline on the reverse osmosis system 10, so as to extract the scale inhibitor in the cylinder 20 and transport it to the reverse osmosis system 10.

[0035] like Figure 2 and Figure 3 As shown, the mixing module includes a mixing chamber 40 fixedly mounted on the top wall of the cylinder 20, and the mixing chamber 40 has a liquid inlet and a liquid outlet, and the liquid outlet of the mixing chamber 40 is connected to the liquid extraction pipe 23. An impeller 41 is rotatably mounted at the liquid inlet of the mixing chamber 40. When the scale inhibitor enters the mixing chamber 40 from the liquid inlet, the impeller 41 can be driven to rotate. A stirring blade 42 is also rotatably mounted in the mixing chamber 40. The stirring blade 42 is transmission-connected to the impeller 41. Gears (not shown in the figure) are provided on the rotating shafts of the stirring blade 42 and the impeller 41, and the two gears are meshed, so that the impeller 41 can drive the stirring blade 42 to rotate. The stirring blade 42 can stir and mix the scale inhibitor entering the mixing chamber 40. The blades of the stirring blade 42 are evenly distributed with through holes, thereby reducing the resistance of the stirring blade 42 when rotating.

[0036] like Figure 5 As shown, the supporting module includes a connecting pipe 50 vertically fixedly installed at the bottom of the mixing chamber 40. The connecting pipe 50 is coaxially arranged with the cylinder 20, and the upper end of the connecting pipe 50 is connected with the liquid inlet of the mixing chamber 40, and the bottom of the connecting pipe 50 is connected with the liquid extraction module, so that the scale inhibitor in the cylinder 20 will enter the connecting pipe 50 after passing through the liquid extraction module, and finally enter the mixing chamber 40 through the connecting pipe 50 for mixing, and finally be extracted by the liquid extraction module.

[0037] like Figures 4 to 7 As shown, the liquid taking module includes an upper liquid suction plate 60 , a lower liquid suction plate 61 , a concentration detection member 64 and a floating plate 80 .

[0038] The upper liquid suction plate 60 and the lower liquid suction plate 61 have the same structure, wherein the lower liquid suction plate 61 is fixedly installed at the bottom of the cylinder 20, the floating plate 80 is fixedly installed above the upper liquid suction plate 60, and the floating plate 80 and the upper liquid suction plate 60 are slidably installed on the connecting pipe 50, and the two can slide up and down along the axial direction of the connecting pipe 50.

[0039] The upper liquid suction disc 60, the lower liquid suction disc 61 and the floating plate 80 are all arranged coaxially with the connecting tube 50. A sliding groove 51 is provided on the outer wall of the connecting tube 50 along its axial direction, and a sliding block 53 matching the sliding groove 51 is provided on the upper liquid suction disc 60, so that the upper liquid suction disc 60 and the floating plate 80 can slide up and down along the outer wall of the connecting tube 50.

[0040] A concentration detection component 64 is installed on both the upper suction plate 60 and the lower suction plate 61. In this embodiment, the concentration detection component 64 is a scale inhibitor concentration sensor. The concentration detection component 64 on the upper suction plate 60 is installed at its bottom, and the concentration detection component 64 on the lower suction plate 61 is installed at its top.

[0041] The floating plate 80 is always floating on the upper surface of the antiscalant due to the buoyancy of the antiscalant in the cylinder 20, so that the upper liquid suction plate 60 is always located near the upper liquid surface of the antiscalant. As the antiscalant is used, the liquid level will drop, and the floating plate 80 will also gradually drop with the upper liquid suction plate 60.

[0042] When the scale inhibitor settles and stratifies after being left in the cylinder 20 for too long, the scale inhibitor concentration at the bottom is greater than that at the upper layer. When the scale inhibitor needs to be extracted, the concentration detection element 64 on the upper suction plate 60 will monitor the concentration of the upper layer of scale inhibitor in real time, and the concentration detection element 64 on the lower suction plate 61 will monitor the concentration of the bottom scale inhibitor in real time, so that the upper suction plate 60 and the lower suction plate 61 respectively extract a certain proportion of the scale inhibitor and enter the mixing chamber 40 through the connecting pipe 50 for mixing, so that the extracted scale inhibitor concentration meets the standard.

[0043] like Figure 4 and Figure 5 The bottom of the connecting tube 50 is connected to the lower liquid suction plate 61 through a connecting tube 62, and the bottom of the connecting tube 50 is connected to the upper liquid suction plate 60 through a spiral tube 63. When the upper liquid suction plate 60 is raised or lowered, the spiral tube 63 can be deformed accordingly to ensure the connection between the upper liquid suction plate 60 and the connecting tube 50.

[0044] The upper liquid suction plate 60 and the lower liquid suction plate 61 are both connected to the bottom of the connecting pipe 50. Because the upper liquid suction plate 60 and the lower liquid suction plate 61 are located at different heights, such an arrangement can ensure that the suction force between the connecting pipe 50 and the upper liquid suction plate 60 and the lower liquid suction plate 61 is the same, and the connecting positions of the upper liquid suction plate 60, the lower liquid suction plate 61 and the connecting pipe 50 are on the same plane, thereby avoiding the influence of other factors on the concentration of the extracted antiscalant as much as possible and reducing errors.

[0045] A liquid suction unit and an adjusting unit are provided on both the upper liquid suction plate 60 and the lower liquid suction plate 61. For ease of understanding, the liquid suction unit and the adjusting unit are introduced below by taking the lower liquid suction plate 61 as an example.

[0046] like Figure 6 As shown, the liquid suction unit includes a liquid collection cavity 65 opened on the lower liquid suction plate 61. It is particularly noted that the liquid collection cavity 65 on the lower liquid suction plate 61 is connected to the connecting tube 50 through a connecting tube 62, and the liquid collection cavity 65 on the upper liquid suction plate 60 is connected to the connecting tube 50 through a spiral tube 63.

[0047] A plurality of liquid inlet channels 66 are evenly provided on the outer peripheral wall of the lower liquid suction plate 61 along its circumference, and the liquid inlet channels 66 are all arranged horizontally and communicated with the liquid collection chamber 65. The scale inhibitor in the cylinder 20 can enter the liquid collection chamber 65 through the liquid inlet channels 66, and then enter the connecting pipe 50 from the liquid collection chamber 65.

[0048] The regulating unit is used to control the flux size of the liquid inlet channel 66 , thereby controlling the amount of the antiscalant passing through the liquid inlet channel 66 .

[0049] Continue back Figure 6 and Figure 7 The regulating unit includes an annular cavity 70 provided on the lower liquid suction plate 61. A vertical regulating cavity 71 is provided on the annular cavity 70 at a position corresponding to each liquid inlet channel 66. The regulating cavity 71 vertically penetrates the liquid inlet channel 66. An regulating plug 72 is sealed and slidably installed in the regulating cavity 71. A triangular regulating hole 73 is provided on the regulating plug 72. The regulating plug 72 is raised and lowered in the regulating cavity 71 to change the area of ​​the connection between the regulating hole 73 and the liquid inlet channel 66, thereby adjusting the flux size of the liquid inlet channel 66. It is particularly emphasized that the regulating hole 73 is set as a triangular structure, which can more sensitively control the flux size of the liquid inlet channel 66.

[0050] A fixing ring 74 is fixedly installed on the adjusting plug 72, and the fixing ring 74 fixes all the adjusting plugs 72 together. A driving member 75 is fixedly installed in the annular cavity 70, and the driving member 75 is a micro cylinder. The telescopic part of the driving member 75 is connected to the fixing ring 74, so that all the adjusting plugs 72 can be driven to rise and fall synchronously at the same time.

[0051] The concentration detection parts 64 on the upper liquid suction plate 60 and the lower liquid suction plate 61 detect the concentration of the upper and bottom antiscalants in real time. After accurate calculation by the control panel, the flux of the liquid inlet channel 66 on the upper liquid suction plate 60 and the lower liquid suction plate 61 is adjusted at the same time, so that the antiscalants drawn into the upper liquid suction plate 60 and the lower liquid suction plate 61 finally enter the mixing chamber 40 through the connecting pipe 50 and the concentration after mixing can meet the addition standard.

[0052] After the scale inhibitor in the cylinder 20 is used up, a small amount of residue will be left at the bottom that cannot be sucked away. Since the concentration of the scale inhibitor added each time is different depending on the quality of the water being treated, if the residual scale inhibitor at the bottom is not completely cleaned up, it will affect the concentration of the scale inhibitor added into the cylinder 20 next time, affecting the use effect. The present invention solves this problem through a scraping module.

[0053] like Figure 5 and Figure 8 As shown, the scraping module includes a plurality of mounting ears 90 circumferentially arranged on the peripheral wall of the floating plate 80, on which a slide bar 91 is vertically slidably mounted. The cross section of the slide bar 91 is a square structure, and an arc-shaped scraper blade 92 is fixedly mounted at the lower end of the slide bar 91.

[0054] A spiral groove 52 is also provided on the outer peripheral wall of the connecting pipe 50 near the lower end, and the upper end of the spiral groove 52 is connected to the slide groove 51. Therefore, when the upper suction plate 60 descends along the connecting pipe 50 to the spiral groove 52, as the scale inhibitor liquid level continues to drop, the weight of the floating plate 80 and the upper suction plate 60 itself will also give the upper suction plate 60 a downward force, so that the upper suction plate 60 rotates while descending along the spiral groove 52.

[0055] When the upper liquid suction disc 60 descends to the upper end of the spiral groove 52, the lower surface of the scraper 92 just contacts the bottom wall of the cylinder 20, and the scraper 92 is located in the annular chamber formed between the lower liquid suction disc 61 and the inner wall of the cylinder 20. At this time, one end of the scraper 92 contacts the inner wall of the cylinder 20, and the other end contacts the outer peripheral wall of the lower liquid suction disc 61 (such as Figure 8), when the upper liquid suction disc 60 rotates while descending along the spiral groove 52, the floating plate 80 drives the scraper 92 to rotate, and the mounting ear 90 continues to slide downward along the slide rod 91. Since the scraper 92 is an arc-shaped structure, the scale inhibitor remaining at the bottom of the cylinder 20 will be scraped to the lower liquid suction disc 61 during the rotation of the scraper 92, and finally sucked away by the liquid inlet channel 66 on the lower liquid suction disc 61, completing the cleaning of the scale inhibitor remaining at the bottom of the cylinder 20.

[0056] The working principle of the present invention is that the floating plate 80 is always floating on the upper surface of the antiscalant due to the buoyancy of the antiscalant in the cylinder 20, so that the upper liquid suction plate 60 is always located near the upper liquid surface of the antiscalant. As the antiscalant is used, the liquid level will drop, and the floating plate 80 will also gradually drop with the upper liquid suction plate 60. When it is necessary to extract the scale inhibitor, the metering pump 21 works, and the scale inhibitor in the cylinder 20 can enter the liquid collection chamber 65 through the liquid inlet channel 66, and then enter the connecting pipe 50 from the liquid collection chamber 65. The concentration detection member 64 on the upper liquid suction disc 60 and the lower liquid suction disc 61 detects the concentration of the upper and bottom scale inhibitors in real time. After accurate calculation by the control panel, the flux size of the liquid inlet channel 66 on the upper liquid suction disc 60 and the lower liquid suction disc 61 is adjusted simultaneously through the adjusting plug 72, so that the upper liquid suction disc 60 and the lower liquid suction disc 61 respectively extract a certain proportion of the upper scale inhibitor and the bottom scale inhibitor, and the extracted scale inhibitor enters the mixing chamber 40 from the connecting pipe 50. When the scale inhibitor enters the mixing chamber 40 from the liquid inlet through the connecting pipe 50, it can drive the impeller 41 to rotate, and the impeller 41 drives the stirring blade 42 to rotate. The stirring blades 42 can stir and mix the scale inhibitor entering the mixing chamber 40 , and the concentration after mixing can meet the addition standard. The mixed scale inhibitor is pumped into the reverse osmosis system 10 through the metering pump 21 .

[0057] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
