Description

Technical Field

[0001] The invention relates to the technical field of pH detection, and in particular to a real-time pH detection mechanism for a reverse osmosis water treatment device. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as a driving force to separate solvents from solutions. When pressure is applied to the liquid on one side of the membrane, when the pressure exceeds its osmotic pressure, the solvent will reversely penetrate in the direction of natural penetration. As a result, the permeated solvent, i.e., the permeate, is obtained on the low-pressure side of the membrane; the concentrated solution, i.e., the concentrate, is obtained on the high-pressure side.

[0003] Reverse osmosis equipment is commonly used in the preparation of high-purity water, desalination of brackish water and wastewater treatment. The permeate is obtained by pressurizing the raw liquid through the reverse osmosis membrane. The principle is that when the raw liquid passes through the reverse osmosis membrane, the water molecules in the raw liquid will pass through the reverse osmosis membrane, while some macromolecular substances, microorganisms and minerals will be retained. Therefore, the pH value of the permeate will change accordingly compared with the pH value of the raw liquid. Therefore, it is necessary to test the pH of the permeate. When the pH is abnormal, the reverse osmosis membrane needs to be replaced. Conventional pH detection methods mostly use test paper or pH meter for sampling detection. This detection method cannot detect the generated permeate in real time. There is a detection time difference, so it is impossible to judge the abnormality of the pH of the permeate in the first time. Some substandard permeate will be mixed with qualified permeate, affecting the overall quality of the permeate. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 - Figure 3 and Figure 5, a real-time detection mechanism for pH value of a reverse osmosis water treatment device shown in the figure comprises a tee installed on the outlet pipe of the reverse osmosis membrane group, detection tubes 1 are fixed at both ends of the tee, and also comprises an insertion tube 2 fixedly connected to the detection tube 1, and a sealing assembly 3 is installed in the insertion tube 2; and two support frames 4, the two support frames 4 are respectively located on the outsides of the two detection tubes 1, an outer tube 5 is fixed on the support frame 4, a track groove 6 is opened on the outer tube 5, a track plate 7 is slidably inserted in the track groove 6, a lifting mechanism 8 for driving the track plate 7 to rise and fall is installed in the outer tube 5, an arc plate 9 that slides and fits with the outer tube 5 is fixed on the outside of the track plate 7, and a detection unit 10 for detecting pH value of liquid in the insertion tube 2 is installed on the outside of the arc plate 9; and a cleaning mechanism 11 fixed on the support frame 4, the cleaning mechanism 11 is used to remove residual liquid at the detection end of the detection unit 10;

[0032] In this solution, the permeate can flow through the two detection tubes 1 through a three-way pipe, and the detection unit 10 is extended into the insertion tube 2, so that the permeate just separated by the reverse osmosis equipment can be detected, and the pH value of the permeate can be detected at the first time to avoid the mixing of some permeate with substandard pH value with the permeate that meets the standard due to untimely detection, thereby reducing the quality of the permeate.

[0033] It should also be noted that at least two detection units 10 are designed in the present scheme. The two detection units 10 cooperate with the lifting mechanism 8 to perform corresponding lifting and lowering, and cooperate with the track plate 7 and the track groove 6 to drive the detection unit 10 to rotate to the cleaning mechanism 11. The cleaning mechanism 11 is used to clean the detection end of the detection unit 10 to remove residual water stains on the outside. The two detection units 10 are used in turn to avoid the detection unit 10 being immersed in the penetrant for a long time, resulting in a slower response speed and reduced accuracy. At the same time, rotating detection may make it more convenient for personnel to perform corresponding inspection and maintenance on the detection unit 10.

[0034] For further information, see Figure 5 , Figure 6 as well as Figure 8 The lifting mechanism 8 includes a threaded rod 12 rotatably mounted in the outer tube 5, a moving seat 13 is threadedly sleeved on the outer side of the threaded rod 12, the outer side of the moving seat 13 is fixed to the track plate 7, a transmission gear 14 is fixed to the bottom end of the threaded rod 12, a lifting motor 15 is fixed on the support frame 4, and a driving gear 16 meshing with the transmission gear 14 is fixed to the output end of the lifting motor 15;

[0035] Meanwhile, referring to the figure, the track groove 6 is composed of a vertical groove 17, a transverse groove 18 and a vertical groove 2 19. Both ends of the transverse groove 18 are connected to the vertical groove 17 and the vertical groove 2 19 respectively. The vertical groove 17 and the vertical groove 2 19 correspond to the insertion tube 2 and the cleaning mechanism 11 respectively.

[0036] The principle of the lifting mechanism 8 driving the detection unit 10 to perform lifting and rotation is as follows: first, when ascending, the driving gear 16 drives the transmission gear 14 to rotate through the operation of the lifting motor 15, thereby causing the threaded rod 12 to rotate accordingly, and the track plate 7 fixed on the outside of the moving seat 13 moves up along the vertical groove 17 until it moves up to the horizontal groove 18. At this time, the rotation of the threaded rod 12 will drive the moving seat 13 and the track plate 7 to rotate along the horizontal groove 18, thereby driving the detection unit 10 to rotate to the cleaning mechanism 11 accordingly, until it is aligned with the vertical groove 2 19, and then continues to move up along the vertical groove 2 19;

[0037] When moving downward, the lifting motor 15 rotates in the opposite direction, causing the threaded rod 12 to rotate in the opposite direction accordingly, so that the movable seat 13 first moves downward along the vertical groove 19, and then moves down to the horizontal groove 18, and then the detection unit 10 is correspondingly rotated from the cleaning mechanism 11 to the top of the insertion tube 2, and then the movable seat 13 drives the detection unit 10 to move downward and extend into the insertion tube 2 for detection.

[0038] For further information, see Figure 2 , Figure 3 and Figure 6 The detection unit 10 includes a pH meter 20 and a connecting plate 21. The connecting plate 21 is fixed to the outer wall of the arc plate 9. A docking sleeve 22 is rotatably installed on the outer end of the connecting plate 21. The pH meter 20 is inserted into the docking sleeve 22. The outer side of the pH meter 20 is screwed with the inner wall of the docking sleeve 22. A rotating member 23 for driving the pH meter 20 to rotate is installed on the connecting plate 21. The bottom of the pH meter 20 extends into the insertion tube 2 and pushes open the sealing component 3.

[0039] It should be noted that the outer shell of the pH meter 20 is cylindrical, and is engraved with threads that are threadedly plugged into the inner wall of the docking sleeve 22 , so that personnel can easily install and remove the pH meter 20 .

[0040] For further information, see Figure 2 - Figure 4 The sealing assembly 3 includes a sealing plate 27 and an abutting ring 28 fixed to the top of the insertion tube 2. A plug plate 29 is fixed to the inner wall of the insertion tube 2 through a bracket. A plug rod 30 plugged with the plug plate 29 is fixed to the bottom of the sealing plate 27. An extrusion spring 31 abutting against the plug plate 29 and the sealing plate 27 is sleeved on the outer side of the plug rod 30.

[0041] At the same time, a contact ring 32 that fits with the abutment ring 28 is fixed to the bottom of the pH meter 20. The contact ring 32 is made of rubber material. After moving downward and contacting and squeezing with the abutment ring 28, it can fit and seal the top of the insertion tube 2.

[0042] In this solution, when the pH meter 20 is inserted into the insertion tube 2 and before the sealing assembly 3 is opened, the detection end at the bottom of the pH meter 20 will first contact the sealing plate 27, and then the sealing plate 27 will be pressed down to move the sealing plate 27 downward, and the detection end of the pH meter 20 will extend into the insertion tube 2 and contact the permeate in the insertion tube 2 to detect its pH value. At the same time, when the pH meter 20 is extended into the insertion tube 2, the contact ring 32 on the outside of the pH meter 20 will abut against the abutting ring 28 to seal the insertion tube 2 to prevent the permeate from overflowing.

[0043] When the pH meter 20 moves upward, its detection end will move upward. At this time, the sealing plate 27 will follow the upward movement under the action of the extrusion spring 31 and abut against the bottom of the abutting ring 28 to seal the insertion tube 2 to prevent the permeate from overflowing from the insertion tube 2.

[0044] In this scheme, a method for real-time pH detection of the permeate separated by the reverse osmosis equipment is provided;

[0045] First, the pH meter 20 in the detection unit 10 is moved downward into the insertion tube 2 by the lifting mechanism 8, and the permeate in the detection tube 1 is detected in real time;

[0046] Secondly, after the real-time detection time of one of the detection units 10 reaches the specified time, it is lifted up by the lifting mechanism 8 and rotated to the cleaning mechanism 11 to clean and dry its detection end;

[0047] Finally, the cleaned detection unit 10 is moved down and rotated to reset, and then inserted into the insertion tube 2 for real-time detection, while the other detection unit 10 is moved up and wiped. The two detection units 10 are raised and lowered in turn to detect the real-time pH value of the permeate.

[0048] In this solution, the specified time of the real-time detection time can be designed to be 3 hours. Every 3 hours, one of the detection units 10 is lifted and wiped, and then inserted again after half an hour. The two detection tubes 1 have a certain length, and the ends of the two detection tubes 1 away from the insertion tube 2 are connected by a three-way pipe. At the same time, a solenoid valve is installed at the other end of the three-way pipe. During the detection process of the pH meter 20, when the pH value of the permeate is detected to be abnormal, the solenoid valve in the three-way pipe at the other end of the detection tube 1 is closed, so that the residual liquid in the detection tube 1 no longer flows into the permeate that meets the standard, thereby avoiding the mixing of the permeate that meets the standard with the permeate that does not meet the standard;

[0049] It should also be noted that the detection tube 1 has a certain length and can store a certain amount of permeate. The insertion tube 2 is located at the end of the detection tube 1. When the insertion tube 2 detects abnormal pH of the permeate, the solenoid valve is closed and the abnormal permeate can all remain in the detection tube 1.

[0050] Example 2: Please refer to Figure 3 as well as Figure 6 - Fig.10 This embodiment further explains the first embodiment, and the difference lies in that one embodiment of the cleaning mechanism 11 and the rotating member 23 is disclosed.

[0051] Specifically, the cleaning mechanism 11 includes two cleaning plates 33 and two supporting plates 34 fixed on the supporting frame 4, the cleaning plates 33 are provided with notches 35 adapted to the detection end of the pH meter 20, two plug-in plates 36 slidably plugged with the inner walls of the supporting plates 34 are fixed on one side of the two cleaning plates 33, and an adjusting component 37 for driving the plug-in plates 36 to move is installed between the two supporting plates 34, a support plate is fixed to the outer side of one of the supporting plates 34, a rolled cleaning belt 38 is installed on the support plate, and the cleaning belt 38 is wound around the outer side of the cleaning plate 33, both ends of the cleaning plate 33 are rotatably installed with fitting columns 39 that fit with the cleaning belt 38, one end of the cleaning plate 33 is rotatably installed with a driving column 40, a micro motor 41 is fixed to the bottom of the cleaning plate 33 through a motor frame, and the output end of the micro motor 41 is fixed to the driving column 40;

[0052] The adjusting assembly 37 includes an adjusting motor 42 and two adjusting plates 43. The adjusting motor 42 is fixed to the outer wall of the supporting plate 34 through a motor frame. The output end of the adjusting motor 42 is fixed to the two adjusting plates 43. A linkage protrusion 44 is fixed to the plug-in board 36. A sliding opening 45 adapted to the linkage protrusion 44 is provided on the adjusting plate 43.

[0053] Meanwhile, the rotating member 23 includes a rotating motor 24 fixed on the connecting plate 21 , a rotating gear 25 is fixed to the output end of the rotating motor 24 , and a gear ring 26 meshing with the rotating gear 25 is fixed to the bottom of the docking sleeve 22 .

[0054] The principle of cleaning and wiping the pH meter 20 by the cleaning mechanism 11 is as follows: the detection unit 10 is driven to move upward and rotate to the cleaning mechanism 11 by the lifting mechanism 8. At this time, the two adjustment plates 43 are rotated correspondingly by adjusting the motor 42, thereby driving the two linkage protrusions 44 to move correspondingly, so that the cleaning plate 33 at the bottom is extended and fits with the detection end at the bottom of the pH meter 20. At this time, the rotating motor 24 drives the rotating gear 25 to rotate, driving the corresponding rotation of the gear ring 26, so that the docking sleeve 22 and the pH meter 20 rotate accordingly, so that the detection end at the bottom of the pH meter 20 fits and wipes with the cleaning belt 38, and the residual liquid on the outside thereof can be removed;

[0055] Then, the pH meter 20 continues to move upward through the lifting mechanism 8, and the motor 42 is adjusted to rotate in the opposite direction, so that the cleaning plate 33 located above is extended, and the cleaning belt 38 located above is driven to fit the detection end of the pH meter 20 for a second wipe, which can effectively remove the residual liquid at the detection end of the pH meter 20.

[0056] In this solution, the corresponding extension and retraction of the two cleaning plates 33 will correspondingly drive the cleaning plates 33 away from and close to the support plate 34, so that the rolled cleaning tape 38 on the support plate 34 will be pulled accordingly, and then the rotation of the micro motor 41 will cause the driving column 40 to rotate accordingly, and the contact between the fitting column 39 and the cleaning tape 38 can be driven to be pulled out accordingly, so that when the detection end of the pH meter 20 is wiped subsequently, a new section of the cleaning tape 38 can be replaced for corresponding cleaning.

[0057] Example 3: Please refer to Fig.10 This embodiment further explains other embodiments, and the difference lies in that the structure of the cleaning plate 33 located below is optimized.

[0058] Specifically, a cavity 46 is provided inside the cleaning plate 33 at the bottom, a through hole 47 communicating with the outside is provided inside the cavity 46 , and a water pipe 48 is fixedly connected to the cleaning plate 33 .

[0059] In this solution, the water supply device is connected to the outside through the water pipe 48, so that the cavity 46 can be filled with water and discharged outward through the port 47. The water directly soaks the cleaning belt 38 to make it moist. During subsequent cleaning, the detection end of the pH meter 20 will first contact the moistened cleaning belt 38, and its detection end will be cleaned first, and then contacted with the cleaning belt 38 located above, and the cleaned detection end of the pH meter 20 will be wiped to achieve a better cleaning effect.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
