[0002] The make-up water source for power plant boilers is generally circulating wastewater softened with lime, and due to the high concentration factor of the circulating water, the salt content of the wastewater is high, making traditional ion exchange desalination processes unable to meet current sewage treatment requirements. Currently, reverse osmosis is the mainstream desalination process for power plant boiler make-up water, and the core of the reverse osmosis device is the reverse osmosis membrane element. During daily operation and maintenance, if the conductivity is found to be high, the membrane must be removed for testing.

[0021] Example 1 Referring to FIGS. 1 and 2, a first embodiment of the present invention provides an inspection device for efficiently attaching and detaching a reverse osmosis membrane, which includes a fixing unit 100 and an inspection unit 200. The reverse osmosis membrane to be inspected is placed in the fixing unit 100, and both ends of the reverse osmosis membrane are connected by the inspection unit 200, after which the reverse osmosis membrane can be inspected.

[0024] A water inlet pipe 203 is provided on one side of the second fixed base 102, and the water inlet pipe 203 is equipped with a high-pressure pump, a pressure gauge, a flow meter, and a conductivity meter.The water to be filtered is sent into the water inlet pipe 203 by the high-pressure pump, and the water pressure is measured by the pressure gauge and the water flow rate is measured by the flow meter.The conductivity meter can measure the conductivity within the water inlet pipe 203.

[0025] The first fixed base 101 and the second fixed base 102 are both provided with a movable connection assembly 204, which drives the water inlet pipe 203 and one end of the fresh water outlet pipe 201 to move and contact both ends of the reverse osmosis membrane, respectively, thereby enabling the performance of the reverse osmosis membrane to be inspected.

[0026] The positioning assembly 103 further includes a fastening member 103a movably mounted on the first fixed base 101 and the second fixed base 102, one end of the fastening member 103a being hingedly connected to the first fixed base 101 or the second fixed base 102, the lower end of the fastening member 103a being arc-shaped and provided with a rubber pad that matches the reverse osmosis membrane for pressing and fixing the reverse osmosis membrane, the side wall of the fastening member 103a being provided with a guide groove 103a-1, one part of the guide groove 103a-1 being parallel to the uppermost end of the fastening member 103a and the other part being inclined downward, a hydraulic cylinder 103b being provided on one side of the fastening member 103a and fixedly attached to the first fixed base 101 and the second fixed base 102, a push rod 103c being fixedly connected to the extended end of the hydraulic cylinder 103b, and both ends of the push rod 103c extending into the guide groove 103a-1.

[0027] While the hydraulic cylinder 103b is extended, the push rod 103c is pushed to move along the guide groove 103a-1, thereby pushing the fastening member 103a to rotate, so that the fastening member 103a forms a closed space with the first fixed base 101 or the second fixed base 102, and the reverse osmosis membrane located inside the closed space is pressed against it, and here, the reverse osmosis membrane can be pressed and protected by installing a rubber pad.

[0028] Furthermore, the movable connection assembly 204 includes a fixed plate 204a provided on the first fixed base 101 and the second fixed base 102, the fixed plate 204a being located on one side of the first fixed base 101 and the second fixed base 102, and being vertically installed on the first fixed base 101 and the second fixed base 102, respectively; a movable plate 204b is provided on the fixed plate 204a, the bottom end of the movable plate 204b is slidably connected to the surface of the fixed plate 204a; and an elastic hose 204c is provided on one side of the movable plate 204b, and the elastic hose The flexible hose 204c is connected to the water inlet pipe 203 and the fresh water discharge pipe 201, respectively. When the movable plate 204b moves toward the first fixed base 101 or the second fixed base 102, the flexible hose 204c is pulled and extended, thereby increasing the movement stroke of the water inlet pipe 203 and the fresh water discharge pipe 201. Here, a through hole is opened through the movable plate 204b and communicates with the flexible hose 204c, and the end of the reverse osmosis membrane is communicated with the flexible hose 204c via the movable plate 204b.

Then, the hydraulic cylinder 103b is extended to push the push rod 103c. As the push rod 103c moves, it can move along the guide groove 103a-1 on the fastening member 103a, so that the fastening member 103a is biased downward around the hinge connecting shaft 206c. The reverse osmosis membrane is pressed and fixed by the arc-shaped groove on the first fixed base 101 or the second fixed base, forming a closed space with the arc-shaped groove on the first fixed base 101 or the second fixed base. At the same time, the rubber pad on the arc-shaped concave surface below the fastening member 103a comes into contact with and presses against the surface of the reverse osmosis membrane, thereby improving the stability of fixing the reverse osmosis membrane. At this time, the concentrated water outlet on the reverse osmosis membrane and the concentrated water outlet pipe 202 are tightly inserted through a gasket. Next, the movable plate 204b on the first fixed base 101 and the second fixed base 102 is moved, and the elastic hose 204c is driven to extend, so that both ends of the reverse osmosis membrane are connected to the two The water to be filtered is fed into the reverse osmosis membrane by the high-pressure pump on the water inlet pipe 203.

Measurements are first taken using the flow meter on the water inlet end and the flow meter on the concentrated water outlet pipe 202, and then measured by an automatic flow meter installed on the concentrated water outlet pipe. The recovery rate is adjusted to 75% using a valve, and the salt rejection rate is then calculated from the conductivity measured by the conductivity meter on the water inlet pipe 203 and the conductivity meter on the fresh water outlet pipe 201, thereby enabling the performance of the reverse osmosis membrane to be determined with high accuracy and realizing rapid testing of the reverse osmosis membrane. After the test is completed, the fastening members 103a are opened, the tested reverse osmosis membrane is removed from the first fixing base 101 and the second fixing base 102, and can be replaced with the next reverse osmosis membrane to be tested, thereby simplifying the operation and enabling multiple reverse osmosis membranes to be tested.

[0030] Example 2 3 to 5, which show a second embodiment of the present invention, this embodiment differs from the first embodiment in the following respects: The inspection unit 200 further includes an insertion tube 205a attached to a movable plate 204b, the movable plate 204b having a through-hole formed therethrough, the insertion tube 205a being connected to an expandable hose 204c via the through-hole, a sealing structure 205b being provided inside the insertion tube 205a and being hermetically connected to an end of the reverse osmosis membrane to prevent leakage, and a moving structure 206 being provided to move the sealing structure 205b to seal the connection portion.

[0031] Furthermore, the sealing structure 205b includes an umbrella-shaped gasket 205b-1 provided inside the insertion tube 205a, the umbrella-shaped gasket 205b-1 is installed at the port of the insertion tube 205a and extends into the inside, there is a gap between the umbrella-shaped gasket 205b-1 and the inner wall of the insertion tube 205a, a position limiting ring 205b-2 is slidably provided inside the insertion tube 205a, the position limiting ring 205b-2 is located outside the umbrella-shaped gasket 205b-1, its inner ring-shaped wall is attached to the outside of the umbrella-shaped gasket 205b-1, and one end of the position limiting ring 205b-2 A plurality of buffer springs 205b-4 are provided, one end of which is connected to the inner wall of the insertion tube 205a. A positioning ring 205b-3 is slidably provided inside the insertion tube 205a. A buffer member, which may be a spring member or a damping elastic member, is provided between the positioning ring 205b-3 and the moving plate 204b. When the insertion tube 205a and the end of the reverse osmosis membrane are inserted into the insertion tube 205a, the end of the reverse osmosis membrane inserted into the insertion tube 205a abuts against the positioning ring 205b-3 and presses the positioning ring 205b-3 to move it through a certain space.

[0032] Furthermore, the moving mechanism 206 includes a mounting frame 206a installed inside the insertion tube 205a, the mounting frame 206a is fixedly attached to the inner wall of the insertion tube 205a, a moving rod 206b is rotatably installed on the mounting frame 206a, the middle part of the moving rod 206b is hingedly connected to the mounting frame 206a through a movable shaft, and a hinge connection shaft 206c is installed on the side wall of the positioning ring 205b-3, the hinge connection shaft 206c passes through one end of the moving rod 206b and is movably connected to the moving rod 206b, whereby the moving mechanism 206 When the positioning ring 205b-3 is pressed against the end of the reverse osmosis membrane and moves, the movable rod 206b deflects around the movable axis. At this time, one end of the movable rod 206b abuts against one side of the position limiting ring 205b-2, pressing the position limiting ring 205b-2 to move, and the movement of the position limiting ring 205b-2 fastens the umbrella-shaped gasket 205b-1, thereby achieving effective sealing of the connection between the reverse osmosis membrane and the insertion tube 205a, improving the sealing effect, and preventing leakage.

[0033] The remaining structure is the same as that of the first embodiment.

[0034] In use, when the movable plate 204b moves to the end of the reverse osmosis membrane, the insertion tube 205a can be driven to move synchronously. At the same time as the insertion tube 205a moves, the end of the reverse osmosis membrane can be inserted into the insertion tube 205a and abut against the positioning ring 205b-3. At this time, the buffer member is contracted under the action of pressure, thereby moving the positioning ring 205b-3 toward the movable plate 204b. At the same time, the positioning ring 205b-3 moves. One end of the moving rod 206b can be pulled by the hinge connection shaft 206c, causing the moving rod 206b to deflect around the movable shaft, thereby pressing one end of the moving rod 206b against the position limiting ring, which can move to the end of the insertion tube 205a while compressing the buffer spring 205b-4, thereby fastening the umbrella-shaped gasket 205b-1 and quickly sealing the port connection between the insertion tube 205a and the reverse osmosis membrane, thereby preventing leakage.

[0035] Example 3 Referring to FIGS. 6 and 7, the third embodiment of the present invention differs from the second embodiment in the following respects. The apparatus further includes a driving unit 300, which includes a sliding groove 301 provided in the first fixed base 101 and the second fixed base 102, the sliding groove 301 being provided perpendicular to the surface of the first fixed base 101 or the second fixed base 102, a driving member 302 provided inside the sliding groove 301, and when the fastening member 103a moves downward and contacts the first fixed base 101 or the second fixed base 102, pressure is applied to the driving member 302, a moving member 303 is provided on the fixed plate 204a, and the driving member 302 can trigger the moving member 303 to displace a certain distance, and a moving assembly 304 is provided on the fixed plate 204a, one end of the moving assembly 304 is connected to the moving plate 204b, so that the moving member 303 can be triggered to move the moving assembly 304 at the same time as it moves, and the moving assembly 304 can drive the moving plate 204b to slide on the fixed plate 204a.

[0036] Specifically, the driving member 302 includes a sliding rod 302a, which is a rectangular rod and slidably disposed within the sliding groove 301. A first wedge-shaped block 302b is disposed at the bottom end of the sliding rod 302a. An extension plate is disposed at the top end of the sliding rod 302a. A return spring 302c is disposed within the sliding groove 301. One end of the return spring 302c is connected to the extension plate. When one end of the fastening member 103a no longer contacts the first fixed base 101 or the second fixed base 102, the return spring 302c propels the extension plate upward, thereby moving the sliding rod 302a upward a certain distance. When one end of the fastening member 103a contacts the first fixed base 101 or the second fixed base 102, the extension plate and the sliding rod 302a are propelled downward, and the return spring 302c is compressed.

[0037] Furthermore, the movable member 303 includes a movable rod 303a slidably mounted on the fixed plate 204a. The movable rod 303a is located on one side of the sliding rod 302a and is installed perpendicular to the sliding rod 302a. A second wedge-shaped block 303b is provided at one end of the movable rod 303a. The second wedge-shaped block 303b is coincident with the first wedge-shaped block 302b. A spherical protrusion 303c is provided at the other end of the movable rod 303a. When the second wedge-shaped block 303b is pressed by the first wedge-shaped block 302b, the compression spring installed on the movable rod 303a is pressed and contracted, causing the movable rod 303a to move and propel the spherical protrusion 303c in a direction away from the sliding rod 302a.

[0038] Further, the moving assembly 304 includes a profiled lever 304a mounted on the fixed plate 204a, through which a torsion spring shaft 304b fixedly connected to the fixed plate 204a is passed. One end of the profiled lever 304a is hingedly connected to a traction block, and one end of the traction block is hingedly connected to the moving plate 204b. Here, the spherical protrusion 303c abuts one side of the profiled lever 304a, so that when the moving rod 303a moves, one end of the profiled lever 304a is driven by the spherical protrusion 303c, and the profiled lever 304a can be deflected around the torsion spring shaft 304b. Further, during the deflection of the profiled lever 304a, the moving plate 204b is pulled by the traction block so as to move close to the end of the reverse osmosis membrane, thereby facilitating the rapid insertion of the insertion tube 205a into the end of the reverse osmosis membrane.

[0039] The remaining structure is the same as that of Example 2.

[0040] In use, when one end of the fastening member 103a contacts the first fixed base 101 or the second fixed base 102, the extension plate and the slide rod 302a are pushed to move downward, and the return spring 302c can be compressed. The slide rod 302a moves downward inside the slide groove 301 and pushes the first wedge-shaped block 302b to move downward. The first wedge-shaped block 302b moves downward and simultaneously presses the second wedge-shaped block 303b to move, thereby pressing the slide rod 303a. The compression spring is pressed and contracted, and at the same time, the movable rod 303a is pushed to move the spherical protrusion 303c in a direction away from the slide rod 302a, and one end of the profiled lever 304a is pushed to perform a pressing action, whereby the profiled lever 304a is deflected around the torsion spring axis 304b. Further, while the profiled lever 304a is deflecting, the movable plate 204b is pulled by the pulling block so as to move closer to the end of the reverse osmosis membrane, thereby facilitating the rapid insertion of the insertion tube 205a into the end of the reverse osmosis membrane.
