Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane technology, specifically to a curtain-type ultrafiltration membrane frame fastening device. Background Technology

[0002] In ultrafiltration membrane water treatment processes, curtain-type ultrafiltration membrane elements typically need to be installed side-by-side within a large frame structure to form a complete membrane stack module. This frame is usually composed of multiple independent frame units, therefore, rapid, precise, and secure connection and fastening between the frame units is crucial.

[0003] Existing methods for connecting and fastening curtain-type ultrafiltration membrane frames typically involve first pushing or prying the two frames into roughly their positions, then adjusting their relative positions visually and based on experience to minimize misalignment, before using standard fasteners such as bolts and clamps for initial fixation. This adjustment process involves repeated cycles of tightening, measuring, loosening, fine-tuning, and tightening until the frame connections meet basic flatness and straightness requirements. This results in lengthy on-site installation and adjustment times and low construction efficiency. Utility Model Content

[0004] This utility model provides a curtain-type ultrafiltration membrane frame fastening device to solve the problems of long on-site installation and adjustment time and low construction efficiency mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a curtain-type ultrafiltration membrane frame fastening device, comprising a connecting frame, and further comprising: a fine-tuning track disposed at one end of the connecting frame, wherein V-shaped guide channels are symmetrically opened on both sides of the bottom surface of the fine-tuning track, and a locking block is sleeved inside the V-shaped guide channel; an adjusting stud rotatably disposed on the surface of the connecting frame, wherein a moving rod is threadedly connected to the surface of the adjusting stud, and a pushing component is fixedly disposed at both ends of the moving rod, wherein a fastening block is fixedly disposed at one end of the pushing component.

[0006] As a preferred technical solution of this utility model, the pushing assembly includes a fixed plate A, a pushing rotating rod and a fixed plate B. The fixed plate A is fixedly disposed at one end of the moving rod, and the two ends of the pushing rotating rod are respectively hinged to the fixed plate A and the fixed plate B. The pushing assembly is used to push the two sets of fastening blocks to move towards the middle.

[0007] As a preferred technical solution of this utility model, the fastening blocks are in two sets. One set of fastening blocks has a positioning frame fixedly provided on one side, and the other set of fastening blocks has a limiting rod fixedly provided on one side. The positioning frame and the limiting rod are used to limit the fastening blocks.

[0008] As a preferred technical solution of this utility model, the positioning frame has a cavity inside, and the limiting rod is slidably disposed inside the cavity, which facilitates the sliding of the limiting rod.

[0009] As a preferred technical solution of this utility model, an anti-slip plate is fixedly provided on the inner wall of the fastening block. The anti-slip plate is made of rubber and is used to increase the friction between the fastening block and the frame.

[0010] As a preferred technical solution of this utility model, a C-shaped anti-slip block is fixedly provided on the inner wall of the locking block. The C-shaped anti-slip block is made of polyurethane and is used to increase the locking force and friction between the locking block and the frame.

[0011] As a preferred technical solution of this utility model, a frame body is sleeved inside the fastening block. The fastening block and the locking block are both in two sets and are symmetrically arranged along the axial direction. A positioning protrusion is fixedly provided on the top surface of the frame body near the locking block. The positioning protrusion prevents the locking block from moving.

[0012] Compared with the prior art, the present invention provides a curtain-type ultrafiltration membrane frame fastening device, which has the following beneficial effects: This curtain-type ultrafiltration membrane frame fastening device, through the setting of a fine-tuning track, fastening blocks, locking blocks, and adjusting studs, engages the locking blocks into the top beams of the two sets of frame bodies. The two sets of fastening blocks are then attached to the steel structures of the two sets of frame bodies. Tightening the adjusting studs moves the moving rod towards the side closer to the frame body, causing the pushing component to push the fastening blocks towards the center position, bringing the two sets of frame bodies closer together. During this approach and connection process, the locking blocks simultaneously move within the V-shaped guide channel of the fine-tuning track. The gradually narrowing trajectory of the V-shaped guide channel allows the locking blocks to gradually align and fit the frame bodies, achieving fine-tuning and centering during the frame body connection and fastening process. This avoids misalignment and deviation that may occur during manual operation, improving installation accuracy and efficiency. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 This utility model discloses a curtain-type ultrafiltration membrane frame fastening device, including a connecting frame 1, and further including: a fine-adjustment track 2 disposed at one end of the connecting frame 1, V-shaped guide channels 3 symmetrically opened on both sides of the bottom surface of the fine-adjustment track 2, and a locking block 4 sleeved inside the V-shaped guide channel 3; an adjusting stud 5 rotatably disposed on the surface of the connecting frame 1, a moving rod 6 threadedly connected to the surface of the adjusting stud 5, a pushing component 7 fixedly disposed at both ends of the moving rod 6, and a fastening block 8 fixedly disposed at one end of the pushing component 7; By setting up the fine-tuning track 2, fastening block 8, locking block 4, and adjusting stud 5, the locking block 4 is locked onto the top beams of the two sets of frame bodies 13, and the two sets of fastening blocks 8 are respectively attached to the steel structure of the two sets of frame bodies 13. Then, the adjusting stud 5 is turned, which drives the moving rod 6 to move closer to the side of the frame body 13, so that the pushing component 7 pushes the fastening block 8 to the center position, causing the two sets of frame bodies 13 to move closer and dock. During the process of moving closer and docking, the locking block 4 moves within the V-shaped guide channel 3 in the fine-tuning track 2. The gradually narrowing trajectory of the V-shaped guide channel 3 causes the locking block 4 to drive the frame body 13 to gradually align and fit together, realizing fine-tuning and centering during the docking and fastening process of the frame body 13, avoiding misalignment and deviation that may occur during manual operation, and improving installation accuracy and efficiency.

[0017] Specifically, the pushing assembly 7 includes a fixed plate A 71, a pushing rod 72, and a fixed plate B 73. The fixed plate A 71 is fixedly disposed at one end of the moving rod 6, and the two ends of the pushing rod 72 are hinged to the fixed plate A 71 and the fixed plate B 73, respectively.

[0018] In this embodiment, turning the adjusting stud 5 causes the moving rod 6 to move towards the side closer to the frame body 13, which in turn causes the pushing rod 72 to push the fastening block 8 towards the center position.

[0019] Specifically, there are two sets of fastening blocks 8. One set of fastening blocks 8 has a positioning frame 9 fixedly installed on one side, and the other set of fastening blocks 8 has a limit rod 10 fixedly installed on one side.

[0020] In this embodiment, during the centering and moving of the two sets of fastening blocks 8, the limiting rod 10 simultaneously slides inside the positioning frame 9, which facilitates the limiting of the two sets of fastening blocks 8.

[0021] Specifically, the positioning frame 9 has a cavity inside, and the limiting rod 10 is slidably disposed inside the cavity.

[0022] In this embodiment, the cavity facilitates the sliding of the limiting rod 10.

[0023] Specifically, the inner wall of the fastening block 8 is fixedly provided with an anti-slip plate 11, which is made of rubber.

[0024] In this embodiment, the anti-slip plate 11 is used to increase the friction at the contact point between the fastening block 8 and the frame body 13.

[0025] Specifically, the inner wall of the locking block 4 is fixedly provided with a C-shaped anti-slip block 12, which is made of polyurethane.

[0026] In this embodiment, the C-shaped anti-slip block 12 is used to increase the friction between the locking block 4 and the frame body 13.

[0027] Specifically, a frame body 13 is fitted inside the fastening block 8. Both the fastening block 8 and the locking block 4 are in two sets and are symmetrically arranged along the axial direction. A positioning protrusion 14 is fixedly provided on the top surface of the frame body 13 near the locking block 4.

[0028] In this embodiment, the positioning protrusion 14 is used to limit the locking block 4.

[0029] The working principle and usage process of this utility model are as follows: The locking block 4 is inserted into the top beams and columns of the two sets of frame bodies 13, and then the fine adjustment track 2 is fastened to the top of the locking block 4. At this time, the locking block 4 is located in the larger opening of the V-shaped guide channel 3. While the fine adjustment track 2 is fastened to the locking block 4, the two sets of fastening blocks 8 are also driven by the connecting frame 1 to attach to the steel structure of the two sets of frame bodies 13 respectively. The length of the fastening block 8 is greater than the width of the beams and columns of the frame body 13, which makes it easy to lock the two sets of misaligned frame bodies 13 into the fastening block 8 in the initial stage. Turning the adjusting stud 5 causes the moving rod 6 to move closer to the frame body 13. At this time, the two fastening blocks 8 are horizontally limited by the cooperation between the positioning rod 9 and the limiting rod 10. As the moving rod 6 moves, it pushes the two fastening blocks 8 to the center position through the rotating rod 72, thereby squeezing the side walls of the two sets of frame bodies 13 and causing the two sets of frame bodies 13 to move closer to each other and connect. During the approaching docking process, the locking block 4 moves simultaneously within the V-shaped guide channel 3 in the fine-tuning track 2. The positioning protrusion 14 is used to limit one end of the locking block 4. The gradually narrowing trajectory of the V-shaped guide channel 3 causes both sets of locking blocks 4 to gradually move towards the center position for alignment, thereby driving the frame body 13 to gradually align and fit towards the center. This achieves fine-tuning and centering during the docking and fastening process of the frame body 13, avoiding misalignment and deviation that may occur during manual operation, and improving installation accuracy and efficiency.
