Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane nonwoven fabric processing technology, specifically to an online monitoring device for the thickness of reverse osmosis membrane nonwoven fabric. Background Technology

[0002] The development of reverse osmosis membrane fabrication technology has led to the current widespread use of reverse osmosis membranes, which primarily consist of a support layer and a functional layer, which can be fabricated separately. The support layer, in particular, supports the entire reverse osmosis membrane, providing the interfacial reaction environment, mechanical strength, and stability necessary for its fabrication and application. Research on the support layer is crucial for improving the performance of reverse osmosis membranes. Currently, non-woven fabric is the primary material used as the support layer for reverse osmosis membranes. However, non-woven fabric support materials prepared using different materials and processes exhibit significant performance differences. Therefore, optimizing the production conditions and product quality of reverse osmosis membranes by improving the fabrication process of non-woven fabric support materials has become a key research focus.

[0003] When processing nonwoven fabrics for reverse osmosis membranes, an online thickness monitoring device is required. During use, the laser rangefinder sensor on the online thickness monitoring device needs to be disassembled and inspected periodically. However, the disassembly process of the laser rangefinder sensor is cumbersome, which makes it inconvenient for staff to maintain the laser rangefinder sensor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an online monitoring device for the thickness of nonwoven fabric in reverse osmosis membranes, which has advantages such as facilitating the disassembly and maintenance of laser ranging sensors, thus solving the problem of inconvenient disassembly and maintenance of laser ranging sensors.

[0005] This utility model discloses an online thickness monitoring device for reverse osmosis membrane nonwoven fabric, comprising a concave plate. A movable component is provided within the inner cavity of the concave plate. The movable component includes a frame. Online thickness monitoring components are located at the top and bottom of the inner cavity of the frame. Each online thickness monitoring component includes a right clamping plate, the outer side of which is fixedly connected to the frame. A laser ranging sensor is snapped onto the left side of the right clamping plate, and a left clamping plate is snapped onto the left side of the laser ranging sensor. A pull rod is located on the left side of the left clamping plate. A connecting plate is sleeved on the surface of the pull rod, and the outer side of the connecting plate is connected to the frame. Springs are provided at both ends of the left clamping plate where it connects to the connecting plate. A sliding sleeve is fixedly sleeved within the inner cavity of the connecting plate, and the inner cavity of the sliding sleeve is movably connected to the pull rod. A handle is located on the left side of the pull rod. When the laser ranging sensor needs to be disassembled and repaired, the handle is pulled first, which drives the pull rod. Move outwards via the sliding sleeve inside the connecting plate and the pull rod. The pull rod then moves the left clamping plate. When the inner side of the left clamping plate is no longer in contact with the laser rangefinder sensor, the laser rangefinder sensor can be removed. Once the laser rangefinder sensor is removed from the right clamping plate, it can be disassembled and properly serviced. After the laser rangefinder sensor is serviced and placed in the designated position, release the handle. The inertia of the spring will cause the left clamping plate to reset. The left and right clamping plates then work together to fix the laser rangefinder sensor in place. This makes the laser rangefinder sensor service more convenient, avoiding the need for periodic disassembly and maintenance of the laser rangefinder sensor on the thickness online monitoring device. However, the disassembly process of the laser rangefinder sensor is cumbersome, leading to inconvenience for staff during maintenance.

[0006] This invention relates to an online thickness monitoring device for reverse osmosis membrane nonwoven fabric. The frame has two fixedly connected threaded sleeves on both sides of its bottom. A screw rod is threaded into the inner cavity of each of the two threaded sleeves. A motor is located on the left side of the screw rod, and the motor's output end is fixedly connected to the screw rod. Slider blocks are located on both sides of the bottom of the frame. Sliding grooves matching the sliders are opened at both ends of the top of the concave plate. When monitoring the thickness of the reverse osmosis membrane nonwoven fabric, the motor first runs, driving the screw rod to rotate in both directions. This drives the threaded sleeves to move, which in turn moves the frame. The sliding grooves in the concave plate and the sliders cooperate with the frame's movement to move the frame. The frame then moves a laser ranging sensor, which monitors the thickness of the reverse osmosis membrane nonwoven fabric. If the thickness is found to be unqualified, the laser ranging sensor transmits the information to a monitoring display screen, allowing staff to make timely adjustments based on the feedback from the display screen.

[0007] The present invention relates to an online thickness monitoring device for reverse osmosis membrane nonwoven fabric, wherein a movable plate is rotatably connected to the right side of the screw surface, and the bottom of the movable plate is fixedly connected to the concave plate. The movable plate can stabilize the screw rotation when it rotates, thus avoiding uneven rotation.

[0008] The present invention relates to an online thickness monitoring device for nonwoven fabric of reverse osmosis membrane, wherein the surface of the handle is covered with an anti-slip sleeve, and the inner cavity of the anti-slip sleeve is fixedly connected to the handle by an adhesive. The anti-slip sleeve can prevent the handle from slipping and prevent the handle from falling off when the user pulls it.

[0009] The present invention relates to an online monitoring device for the thickness of nonwoven fabric in reverse osmosis membranes, wherein mounting plates are fixedly connected to both sides of the front and back sides of the concave plate, and mounting holes are provided in the inner cavity of the mounting plates.

[0010] The present invention relates to an online thickness monitoring device for reverse osmosis membrane nonwoven fabric. The left side of the left clamping plate is fixedly connected to the pull rod by a connecting block, and the right side of the pull rod is located at the center of the left side of the left clamping plate. The connecting block can fix the pull rod, thus improving the pull rod's performance during use and preventing it from becoming loose and falling off.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When the laser rangefinder sensor needs to be disassembled and repaired, this utility model first pulls the handle, which drives the pull rod to move outward. The sliding sleeve inside the connecting plate moves in conjunction with the pull rod, which in turn moves the left clamping plate. When the inner side of the left clamping plate does not contact the laser rangefinder sensor, the laser rangefinder sensor can be removed. When the laser rangefinder sensor is removed from the right clamping plate, the laser rangefinder sensor can be disassembled and repaired normally. After the laser rangefinder sensor is repaired and placed in the designated position, the handle is released. The inertia of the spring drives the left clamping plate to return to its original position. The left clamping plate and the right clamping plate cooperate to fix the laser rangefinder sensor. This makes the laser rangefinder sensor repair more convenient and avoids the need for periodic disassembly and repair of the laser rangefinder sensor on the thickness online monitoring device. However, the disassembly process of the laser rangefinder sensor is cumbersome, which leads to inconvenience for the staff in repairing the laser rangefinder sensor.

[0013] 2. When monitoring the thickness of the nonwoven fabric of the reverse osmosis membrane is required, the present invention first operates a motor, which drives the screw to rotate in both directions, moves the screw sleeve, moves the frame, and moves the sliding groove and slider in the concave plate in conjunction with the frame. The frame then moves the laser rangefinder sensor, which monitors the thickness of the nonwoven fabric of the reverse osmosis membrane. When the thickness of the nonwoven fabric of the reverse osmosis membrane is found to be unqualified, the laser rangefinder sensor transmits the information to the monitoring display screen, and the staff can make timely adjustments based on the information fed back from the display screen.

[0014] The movable plate can stabilize the screw rotation, preventing uneven rotation.

[0015] The connecting block can fix the pull rod, which makes the pull rod more effective during use and prevents it from becoming loose and falling off.

[0016] The anti-slip sleeve prevents the handle from slipping, thus preventing it from falling off when the user pulls it. Attached Figure Description

A handle 206 is provided on the left side of the rod 209. When the laser rangefinder sensor 202 needs to be disassembled and repaired, the handle 206 is pulled first, which drives the rod 209 to move... The laser rangefinder 202 can be moved outwards via the sliding sleeve 208 inside the connecting plate 205 in conjunction with the pull rod 209. The pull rod 209 then moves the left clamping plate 203. When the inner side of the left clamping plate 203 is no longer in contact with the laser rangefinder 202, the laser rangefinder 202 can be removed. Once the laser rangefinder 202 has been removed from the right clamping plate 201, it can be disassembled and repaired. After the laser rangefinder 202 has been repaired and placed in the designated position, the handle can be released. 206. The left clamp 203 is reset by the inertia of the spring. The left clamp 203 cooperates with the right clamp 201 to fix the laser range sensor 202. This makes the laser range sensor 202 easier to maintain and avoids the need to disassemble and maintain the laser range sensor 202 on the thickness online monitoring device regularly. However, the disassembly process of the laser range sensor 202 is cumbersome, which makes it inconvenient for staff to maintain the laser range sensor 202.

Both sides of the bottom of the frame 402 are provided with sliders 405. Both ends of the top of the concave plate 1 are provided with grooves 5 that are compatible with the sliders 405. In this invention, when it is necessary to monitor the thickness of the reverse osmosis membrane nonwoven fabric, the motor 401 first runs, driving the screw rod 403 to rotate in both directions. The motor 401 drives the screw sleeve 406 to move, which in turn drives the frame 402 to move. The sliding groove 5 and the slider 405 in the concave plate 1 work together with the frame 402 to move, which in turn drives the laser rangefinder 202 to move. The laser rangefinder 202 monitors the thickness of the nonwoven fabric of the reverse osmosis membrane. When the thickness of the nonwoven fabric of the reverse osmosis membrane is found to be unqualified, the laser rangefinder 202 transmits the information to the monitoring display screen, and the staff can make timely adjustments based on the information fed back from the display screen.

The sliding sleeve 208 inside the connecting plate 205 moves in conjunction with the pull rod 209. The pull rod 209 then drives the left clamping plate 203 to move. When the inner side of the left clamping plate 203 is no longer in contact with the laser rangefinder sensor 202, the laser rangefinder sensor 202 can be removed. When the laser rangefinder sensor 202 is removed from the right clamping plate 201, the disassembly of the laser rangefinder sensor 202 is complete, and the laser rangefinder sensor 202 can then be repaired normally. After the laser rangefinder sensor 202 is inspected and placed in the designated position, the handle 206 is released. The inertia of the spring drives the left clamp 203 to reset.
