Abstract
Description
Technical Field
[0001] The utility model relates to a reverse osmosis equipment protection system, and more specifically to a structure of the reverse osmosis equipment protection system. Background Art
[0002] In the industrial production of salt lakes, reverse osmosis equipment is needed to treat brine or sewage. The reverse osmosis equipment is composed of a fixed frame, a high-pressure pump and multiple membrane shells (pressure vessels). A reverse osmosis membrane is arranged in the membrane shell. When working, the water on the water inlet side (high-pressure side) is pressurized to the required pressure of the reverse osmosis equipment by the high-pressure pump, and then evenly distributed to each membrane shell. The water molecules on the water inlet side pass through the reverse osmosis membrane to become purified water, and at the same time, pollutants, heavy metals, salt and other impurities are all isolated, thereby removing impurities in the water and producing water that meets the use requirements. Because this process is opposite to the direction of natural osmosis, it is called reverse osmosis.
[0003] like Figure 7 As shown, the mold shell 71 is a cylindrical structure with two ends open, the diameter of the end is larger than the diameter of the main body, and an annular groove is provided on the inner side wall of the end. The end cover 72 is cylindrical and installed in the mold shell 71 to seal the opening of the mold shell 71. The retaining spring 73 is annular and is arranged in the groove to abut against the end cover 72 to fix the end cover 72. When the reverse osmosis equipment is running, the pressure of the liquid on the water inlet side of the membrane shell can reach 7MPa. After long-term operation, the retaining spring will inevitably loosen until the end cover is blown off by the high-pressure liquid. The blown off end cover will injure the staff and damage the surrounding equipment, which can easily cause major accidents and affect normal production. Moreover, after the end cover blows off, sewage will leak and pollute the environment.
[0004] In order to prevent the end covers from flying off, the existing method is usually to regularly inspect all the end covers. However, manual inspection is highly subjective, prone to false detection and missed detection, and cannot detect problems in a timely manner. In addition, it is inefficient, has a long inspection cycle, and is time-consuming and labor-intensive.
[0005] The utility model aims to solve the problem that the end cover of the membrane shell is easily blown off by high-pressure water during long-term operation of the existing reverse osmosis equipment, causing accidents, affecting production and polluting the environment. Utility Model Content

[0031] The reverse osmosis equipment protection system comprises a protection device 1, a detection device 2, a warning device 4, an infrared detector 5 and a control device 6.
[0032] like Figure 1 and Figure 3As shown, the protection device 1 includes a protection bracket 11, a driving mechanism 12 and a protection roller shutter 13. The protection bracket 11 includes a base 111, a crossbeam 112 and two columns 113. The two columns 113 are vertically arranged on the base 111 to maintain a spacing. The crossbeam 112 is horizontally arranged and extends in the front-to-back direction. The two ends are respectively fixedly connected to the upper ends of the two columns 113. Figure 2 .

The main transmission rod 121 is arranged on the upper part of the protective bracket 11 and extends in the front-to-back direction. Both ends are rotatably connected to the two columns 113 through bearings respectively. The rear end of the main transmission rod 121 passes through the column 113 and extends to the outside of the protective bracket 11.
[0036] The main transmission motor 122 is fixedly arranged on the column 113, and the rotating shaft of the main transmission motor 122 is fixedly connected to the rear end of the main transmission rod 121. The rotating shaft of the main transmission motor 122 is colinear with the axis of the main transmission rod 121, and the main transmission rod 121 can be driven to rotate by the main transmission motor 122.
[0037] The auxiliary transmission rod 123 is arranged at the lower part of the protection bracket 11 and extends in the front-to-back direction. Both ends are rotatably connected to the two columns 113 through bearings respectively. The rear end of the auxiliary transmission rod 123 passes through the columns 113 and extends to the outside of the protection bracket 11.
[0038] The auxiliary transmission motor 124 is fixedly arranged on the column 113, and the rotating shaft of the auxiliary transmission motor 124 is fixedly connected to the rear end of the auxiliary transmission rod 123. The rotating shaft of the auxiliary transmission motor 124 and the axis of the auxiliary transmission rod 123 are colinear, and the auxiliary transmission rod 123 can be driven to rotate by the auxiliary transmission motor 124.
[0039] The protective rolling curtain 13 is arranged between the two uprights 113, one end of which is fixedly connected to the main transmission rod 121, and the other end of which is connected to the auxiliary transmission rod 123 through a pull rope 125. A plurality of sliders 131 matching the guide rails 114 are arranged on both the front and rear sides of the protective rolling curtain 13, and the sliders 131 are slidably arranged on the corresponding guide rails 114. The protective rolling curtain 13 can be limited by the cooperation of the guide rails 114 and the pulley to prevent the protective rolling curtain 13 from tilting or shaking.
[0040] The slider on the protective roller shutter is slidably set on the corresponding guide rail, which means that the slider located on the front side of the protective roller shutter is slidably set on the guide rail on the front side of the protective roller shutter, and the slider located on the rear side of the protective roller shutter is slidably set on the guide rail on the rear side of the protective roller shutter.
[0041] Multiple sliders 131 matching the guide rail 114 are provided on both side edges of the protective roller shutter 13, wherein the matching means that the slider 131 can be set on the guide rail 114 and slide along the guide rail 114, and the protective roller shutter 13 is limited and fixed by the cooperation between the guide rail 114 and the slider 131.
[0042] The protective rolling shutter 13 can be an anti-theft door rolling shutter, or other rolling shutters with similar structures, as long as it can be wound and straightened and can block the end cover of the membrane shell from flying off.
[0043] The warning device 4 includes a warning light 41 and an alarm 42, which are arranged on the protection bracket 11. When the retaining spring is loose, the warning light 41 and the alarm 42 are used to warn the staff to take measures as soon as possible to prevent the staff from failing to find the problem in time and causing an accident.
[0044] Two infrared detectors 5 are provided, and the two infrared detectors 5 are relatively arranged on two upright posts 113. The infrared detectors 5 can detect the staff near the high-pressure side of the membrane shell, and timely remind them to prevent the staff from being hurt.
[0045] When the protective device 1 is in use, it is arranged on the high-pressure side of the membrane shell of the reverse osmosis equipment. When the reverse osmosis equipment is in operation, the auxiliary transmission rod 123 is driven to rotate by the auxiliary transmission motor 124. When the auxiliary transmission rod 123 rotates, the protective roller curtain 13 is pulled downward by the pull rope 125 until the lower end of the protective roller curtain 13 is close to the auxiliary transmission rod 123. When the end cover of the membrane shell is blown off by high-pressure water, the end cover of the membrane shell is blocked by the protective roller curtain 13 to prevent the end cover from injuring the staff and damaging the surrounding equipment. When the reverse osmosis equipment stops operating, the main transmission rod 121 is driven to rotate by the main transmission motor 122, and the protective roller curtain 13 is wound onto the main transmission rod 121, and the protective roller curtain 13 is retracted.
[0046] like Figure 4 and Figure 5 As shown, the detection device 2 includes a detection box 21, a travel switch 23, a trigger spring 24 and a laser distance sensor 27. The detection box 21 is fixedly connected to the connecting member 3 and has a detection cavity 22 formed therein.
[0047] The travel switch 23 is fixedly arranged in the detection cavity 22. The trigger spring 24 is strip-shaped and extends in the left-right direction. The left end is located in the detection cavity 22 and connected to the travel switch 23. The right end passes through the detection box 21 and extends to the outside of the detection box 21. A locking piece 25 is arranged at the end.
[0048] The locking piece 25 is arranged vertically, and is fixedly connected to the trigger spring piece 24 on the left side. A pressure sensor 26 is arranged on the right side surface of the locking piece 25 . The locking piece 25 is used to be pressed against the retaining spring of the membrane shell.
[0049] The laser distance measuring sensor 27 is disposed on the right side of the detection box 21 and faces the locking plate 25 , and is used to detect the moving distance of the locking plate 25 .
[0050] The locking plate 25 is pressed against the retaining spring of the membrane shell. When the retaining spring is loose, it will exert force on the locking plate 25 toward the outside of the membrane shell, pushing the locking plate 25 toward the outside of the membrane shell. At this time, the pressure sensor 26 detects that the pressure between the locking plate 25 and the retaining spring increases. When the pressure is greater than the pressure threshold, it can be considered that the retaining spring is loose. For example, the pressure threshold is set to 1 N. When the travel switch 23 or the laser distance sensor 27 detects that the movement distance of the locking plate 25 is greater than the displacement threshold, it can be considered that the retaining spring is loose. For example, the displacement threshold is set to 2 mm.
[0051] By simultaneously detecting the retaining spring through the pressure sensor 26, the travel switch 23 and the laser distance measuring sensor 27, the detection accuracy can be improved, and when the retaining spring is loose, measures can be taken in time to prevent accidents.
[0052] like Figure 4 and Figure 6 As shown, the connecting member 3 is fixedly connected to the membrane shell and is used to fix the detection device 2 on the membrane shell.

The clamping block 31 includes a connecting plate 311 and a first clamping plate 312 and a second clamping plate 313 which are respectively arranged on the upper and lower sides of the connecting plate 311 and are parallel to each other.
[0053] The first clamping plate 312 is provided with a plurality of fastening bolts 314, the adjusting block 32 is fixedly connected to the second clamping plate 313, the adjusting block 32 is provided with an adjusting hole 321 matching the adjusting rod 33, and the adjusting hole 321 extends in the left-right direction. The side surface of the adjusting block 32 is provided with a threaded hole 322 connecting with the adjusting hole 321 and matching the adjusting bolt 34, and the threaded hole 322 extends vertically.
[0054] The adjusting block 32 is provided with an adjusting hole 321 matching with the adjusting rod 33 , wherein matching means that the diameter of the adjusting hole 321 is equal to or slightly larger than the diameter of the adjusting rod 33 , so that the adjusting rod 33 can be inserted into the adjusting hole 321 and slide along the adjusting hole 321 in the left and right directions.
[0055] A threaded hole 322 connected to the adjusting hole 321 and matching with the adjusting bolt 34 is provided on the side of the adjusting block 32. The diameter of the threaded hole 322 is equal to or slightly larger than the diameter of the adjusting bolt 34. The internal thread on the threaded hole 322 has the same pitch and tooth angle as the external thread of the adjusting bolt 34, so that the adjusting bolt 34 can be inserted into the threaded hole 322. The adjusting rod 33 can be fixed by rotating the adjusting bolt 34.
[0056] The adjusting rod 33 extends in the left-right direction, is slidably disposed in the adjusting hole 321 , and the right end is fixedly connected to the detection box 21 . The adjusting bolt 34 is inserted into the threaded hole 322 to fix the adjusting rod 33 .
[0057] like Figure 7 As shown, when installing the detection device 4 on the membrane shell 71, clamp the clamping block 31 on the membrane shell, turn the fastening bolt 314 to fix the clamping block 31 and the membrane shell 71, and then move the adjusting rod 33 in the left and right directions to adjust the position of the detection box 21 so that the locking plate 25 is pressed against the retaining spring 73 on the membrane shell 71, and then turn the adjusting bolt 34 to fix the adjusting rod 33.
[0058] like Figure 8 As shown, the control device 6 is electrically connected to the main drive motor 122 and the auxiliary drive motor 124 on the protective device 1, the travel switch 23, the laser ranging sensor 27 and the pressure sensor 26 on the detection device 2, the infrared detector 5 and the warning device 4, and the reverse osmosis equipment 7.
[0059] When the reverse osmosis equipment 7 is in operation, the control device 6 controls the auxiliary drive motor 124 to rotate, pulls the protective rolling curtain 13 downward, and makes the protective rolling curtain 13 protect the end cover 72 of the membrane shell. When the travel switch 23, the laser distance sensor 27 or the pressure sensor 26 detects that the retaining spring is loose, the control device 6 controls the warning device 4 to issue an alarm. When the infrared detector 5 detects that a person is close to the high-pressure side of the membrane shell, the control device 6 controls the warning device 4 to issue an alarm. When the reverse osmosis equipment 7 stops operating, the control device 6 controls the main drive motor 122 to rotate and roll up the protective rolling curtain 13.
[0060] like Figure 8 As shown, when the utility model is used, the protective device 1 is arranged on the high-pressure side of the membrane shell 71 of the reverse osmosis equipment 7, and a detection device 2 is installed on the high-pressure side of each membrane shell 71. During installation, the clamping block 31 is clamped on the membrane shell, and the fastening bolt 314 is screwed to fix the clamping block 31 and the membrane shell 71, and then the adjusting rod 33 is moved in the left and right directions to adjust the position of the detection box 21 so that the locking plate 25 is pressed against the retaining ring 72 on the membrane shell 71, and then the adjusting bolt 34 is screwed to fix the adjusting rod 33.
[0061] Then the control device 6 is electrically connected to the protective device 1, the infrared detector 5, the warning device 4, the reverse osmosis equipment 7 and each detection device 2. When the reverse osmosis equipment 7 is in operation, the control device 6 controls the auxiliary transmission motor 124 to drive the auxiliary transmission rod 123 to rotate, and pulls the protective roller curtain 13 downward through the pull rope 125 until the lower end of the protective roller curtain 13 is close to the auxiliary transmission rod 123. When the detection device 2 detects that the retaining spring 73 is loose, the control warning device 4 is controlled to sound an alarm. When someone approaches the high-pressure side of the membrane shell 71, the control warning device 4 is controlled to sound an alarm. When the reverse osmosis equipment 7 stops operating, the main transmission rod 121 is driven to rotate by the main transmission motor 122, and the protective roller curtain 13 is wound onto the main transmission rod 121, and the protective roller curtain 13 is retracted.
[0062] The utility model is provided with a protective device 1. When the reverse osmosis equipment 7 is in operation, the auxiliary transmission rod 123 is driven to rotate by the auxiliary transmission motor 124, and the protective rolling curtain 13 is pulled downward, so that the lower end of the protective rolling curtain 13 is close to the auxiliary transmission rod 123. When the end cover 72 of the membrane shell 71 is blown away by high-pressure water, the end cover 72 of the membrane shell 71 is blocked by the protective rolling curtain 13 to prevent the end cover 72 from injuring the staff and damaging the surrounding equipment. When the reverse osmosis equipment 7 stops operating, the main transmission rod 121 is driven to rotate by the main transmission motor 122, and the protective rolling curtain 13 is retracted upward, so that the reverse osmosis equipment 7 can be operated. The problem that the end cover 72 of the membrane shell 71 is blown away by high-pressure water and causes an accident and affects production can be solved.
[0063] The detection device 2 includes a detection box 21, a travel switch 23 and a trigger spring 24. A connector 3 is provided on the detection box 21, and the detection box 21 can be fixed on the membrane shell through the connector 3. The travel switch 23 is arranged in the detection cavity 22. One end of the trigger spring 24 is connected to the travel switch 23, and the other end is provided with a locking piece 25. The locking piece 25 is pressed on the retaining spring. When the retaining spring is loose, the locking piece 25 is pushed to move to the outside of the membrane shell.
