Abstract

The utility model belongs to the field of membrane modules, and provides an integrity detection device for a high-packing-density immersed hollow fiber membrane module, which comprises a frame, a support rotationally connected to the frame, a leak detection barrel fixedly connected to the support, and a telescopic cylinder coupled between the frame and the support, and the telescopic cylinder drives the support and the leak detection barrel to rotate. Therefore, the device is in a horizontal state or a vertical state. The telescopic cylinder drives the support and the leak detection cylinder to rotate, so that the support and the leak detection cylinder can be in a horizontal state or a vertical state. When the membrane module needs to be placed, the leak detection cylinder is in a horizontal state, so that the membrane module can be conveniently placed in the leak detection cylinder; when detection is started, the leak detection cylinder is in a vertical state, and whether the membrane assembly leaks or not can be observed. By switching the two states of the leak detection cylinder, placement, extraction and detection of the membrane module are realized more conveniently, and the detection efficiency is improved.

[0002] As an important filtration and separation device, membrane modules are widely used in the fields of water treatment, chemical engineering, pharmaceuticals, etc. However, during the manufacturing and use processes of membrane modules, tiny leakage points may occur, affecting their filtration performance and service life. Therefore, it is very necessary to conduct leak detection on membrane modules during their production and use processes.

[0003] When testing some relatively large membrane modules, it is relatively complex, involving multiple placements, extractions, and detections, with cumbersome operations and time-consuming processes. In addition, existing devices cannot quickly and accurately determine the leakage situation of membrane modules during the detection process, affecting the detection efficiency and further affecting the production progress. Moreover, defects in the design may lead to unstable situations during the detection process, and may even damage the membrane module, affecting the accuracy of the detection results.

[0020] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those of ordinary skill in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0021] Embodiment 1

[0022] As Figures 1-3As shown, the present invention is an integrity testing device for high-packing-density submerged hollow fiber membrane modules, comprising a frame 1, a bracket 2, a leak detection tube 3, and a telescopic cylinder 4. The bracket 2 is connected to the frame 1 via two pivot joints, with the leak detection tube 3 attached on the side facing away from the frame 1. The telescopic cylinder 4 is pivotally connected to the bracket 2 and the frame 1 at both ends. As shown in the figure, when the telescopic cylinder 4 pulls the bracket 2 to the right, the bracket 2 rotates clockwise around the pivot joint, carrying the leak detection tube 3 until it becomes horizontal. When the telescopic cylinder 4 is lifted to the left, the bracket 2 rotates counterclockwise around the pivot joint, carrying the leak detection tube 3 to a vertical position. When the membrane module needs to be placed, the leak detection tube 3 is positioned horizontally for easy insertion. When testing begins, the leak detection tube 3 is positioned vertically to observe whether the membrane module has leaks. By switching the leak detection tube 3 between the two positions, the placement, removal, and testing of the membrane module are more convenient, improving testing efficiency.

[0023] In this embodiment, the frame 1 is composed of multiple pipe fittings and has a three-dimensional square structure; the bracket 2 is composed of multiple pipe fittings and has a sun-shaped or mesh-shaped structure; the width and length of the bracket 2 are both smaller than the size of the frame 1, so that when the bracket 2 rotates, the bracket 2 structure will not interfere with the frame 1 structure.

[0024] In this embodiment, Figure 1 As shown, the telescopic end of the telescopic cylinder 4 is axially connected to the bracket 2, and the fixed end of the telescopic cylinder 4 is axially connected to the frame 1. The telescopic cylinder 4 is arranged at an angle, and the fixed end of the telescopic cylinder 4 is lower than the horizontal state of the bracket 2. Through this design, the telescopic cylinder 4 can pull the bracket 2 to a horizontal state.

[0025] In this embodiment, the bracket 2 is provided with a plurality of bearing blocks 5 and clamps 6 on the surface facing away from the frame 1. The leak detection tube 3 is placed on the bearing blocks 5, and the clamps 6 are clamped on the outside of the leak detection tube 3, so that the leak detection tube 3 is fixed on the bracket 2, so that the purpose of driving the leak detection tube 3 to move together when the bracket 2 rotates is achieved.

[0026] In this embodiment, the contact surface between the bearing block 5 and the leak detection tube 3 is an arc-shaped surface. The bearing block 5 can be made of rubber material to ensure contact with the leak detection tube 3 and avoid the leak detection tube 3 from deflecting.

[0027] Furthermore, a baffle 7 is connected to the bracket 2, which is on the side away from the telescopic cylinder 4. When the telescopic cylinder 4 pushes the bracket 2 to a vertical state, the baffle 7 contacts the left side of the frame 1, which can prevent the bracket 2 from continuing to rotate counterclockwise, thereby improving the stability of the equipment.

[0028] Furthermore, a support frame 8 is set under the bracket 2. When the bracket 2 is in a vertical state, water is injected into the leak detection tube 3 for detection. At this time, the weight of the leak detection tube 3 increases, and the support member supports the leak detection tube 3, reducing the force of the leak detection tube 3 on the clamp 6, thereby improving the stability and service life of the equipment.

[0029] Working principle of Embodiment 1: When it is necessary to place or extract the membrane module, the telescopic cylinder 4 pulls the bracket 2 to make it rotate clockwise, and the leak detection cylinder 3 is in a horizontal state, facilitating the placement of the membrane module; when starting the detection, the telescopic cylinder 4 pushes the bracket 2 to make it rotate counterclockwise. When the baffle 7 abuts against the frame 1, the leak detection cylinder 3 is in a vertical state, and water is injected into the leak detection cylinder 3 for testing. It is possible to observe from the top of the leak detection cylinder 3 whether there is a leakage problem with the membrane module.

[0030] Embodiment 2

[0031] Embodiment 2 is a technical solution further improved on the basis of Embodiment 1. On the basis of Embodiment 1, a ladder 9 can be added, which can be used for observers to stand on the top of the leak detection cylinder 3 through the ladder 9 during detection, improving the convenience during detection and observation.

[0032] Embodiment 3

[0033] Embodiment 3 is completed on the basis of Embodiment 2. The ladder 9 in this embodiment is a movable ladder, and the movable ladder can be pushed to the side of the leak detection cylinder 3. The movable ladder in this embodiment is in a separated and independent state from the integrity detection device for the high packing density submerged hollow fiber membrane module in Embodiment 1, which is relatively convenient and can be configured according to the on-site situation.

[0034] Embodiment ④

[0035] Embodiment 4 is completed on the basis of Embodiment 2. The ladder 9 in this embodiment is a folding ladder. The folding ladder is on one side of the telescopic cylinder 4, and its two ends are respectively pivotally connected to the frame 1 and the bracket 2, and it contracts or unfolds as the bracket 2 rotates; when the bracket 2 moves clockwise to the horizontal state, the folding ladder contracts accordingly, and when the bracket 2 moves counterclockwise to the vertical state, the folding ladder unfolds accordingly, so as to facilitate the observer to observe the situation inside the leak detection cylinder 3. The folding ladder in this embodiment is in a connected state with the integrity detection device for the high packing density submerged hollow fiber membrane module in Embodiment 1, and the integrated design makes the use of the device more convenient.
