[0039] In related technologies, membrane modules are used to treat wastewater by placing them in the wastewater. A limiting device is typically installed above the membrane module to restrict its upward movement. For example, patent CN222239641U discloses a lifting membrane module limiting device and a membrane device with this limiting device. The limiting device restricts the membrane module from floating during operation to facilitate stable operation and moves away from the membrane module when it needs to be lifted from the wastewater for cleaning, facilitating lifting. However, when the limiting device moves upward under the guidance of a vertically positioned guide member by a large distance, it may be interfered with by the protruding part of the guide member's sidewall during upward movement, causing the limiting device to deform under stress and preventing it from moving upward smoothly.
[0040] In view of this, the present disclosure provides a membrane module limiting device, the upward movement of which is difficult to be interfered with and can be moved smoothly.
[0041] Figure 1 This is a schematic diagram of the structure of a membrane device according to an embodiment of the present disclosure. Figure 2 yes Figure 1 An enlarged view of section A. (See attached image) Figure 1 and Figure 2 The membrane module limiting device 100 disclosed herein includes a guide member 11 and a floating limiting member 12. The guide member 11 is vertically arranged and is positioned adjacent to the membrane module 600, and the side wall of the guide member 11 is provided with a clearance portion 111.
[0042] Optionally, the guide member 11 includes a guide shaft extending vertically, the guide shaft being used to guide the floating limit member 12 when the floating limit member 12 floats, so that the floating limit member 12 can always move in the vertical direction.
[0043] Figure 3 This is a front view of a membrane device according to an embodiment of this disclosure. See also... Figure 3 The plurality of parts to be avoided 111 are arranged at vertical intervals and are mounted on an external carrier 700. For example, the external carrier 700 can be a wall or panel on the sidewall of a sewage tank. One end of each of the plurality of parts to be avoided 111 is fixedly connected to the guide member 11, and the other end is fixedly connected to the external carrier 700, thereby fixing the guide member 11 and improving its stability. Of course, it is understood that the parts to be avoided 111 in this disclosure are not limited to this, and the parts to be avoided 111 can also be other structures protruding from the sidewall of the guide member 11.
[0044] The floating limiting member 12 is used to restrict the floating of the membrane module 600. The floating limiting member 12 is movably fitted onto the guide member 11 via the guide sleeve 121, thereby switching between a blocking position that restricts the upward movement of the membrane module 600 and a position away from the blocking position under the guidance of the guide member 11. Thus, the floating limiting member 12 can restrict the upward movement of the membrane module 600 during operation to facilitate stable operation, and can move upward away from the membrane module 600 when it needs to be lifted from the wastewater for cleaning, facilitating its lifting. Optionally, the lower end of the floating limiting member 12 is provided with a laterally extending blocking portion 124, which abuts against the top of the membrane module 600. The blocking portion 124 has a large contact area with the membrane module 600 when it prevents the membrane module from floating upward, resulting in a good limiting and blocking effect.
[0045] The guide sleeve 121 is provided with a clearance notch 122 for the part to be avoided 111 to pass through during the movement of the floating limit member 12. In other words, during the upward or downward movement of the floating limit member 12, when the guide sleeve 121 passes through the area where the part to be avoided 111 is located, the clearance notch 122 allows the part to be avoided 111 to pass through, so that the part to be avoided 111 cannot interfere with the movement of the floating limit member 12. This ensures that even if the membrane module 600 needs to be lifted to a high height or the floating limit member 12 needs to move upward a long distance, the guide sleeve 121 can smoothly avoid the part to be avoided 111, thereby ensuring that the upward movement of the floating limit member 12 can proceed smoothly.
[0046] Optionally, there are multiple guide sleeves 121, which are vertically spaced apart from the floating limiting member 12. Multiple guide sleeves 121 refer to two or more guide sleeves 121, and the specific number of guide sleeves 121 can be adjusted as needed. It is understood that when there are multiple guide sleeves 121, the guiding and fixing effect between the guide member 11 and the floating limiting member 12 is good, and the floating limiting member 12 is difficult to detach from the guide member 11 during movement.
[0047] Figure 4 This is a top view of the guide sleeve 121 fitted onto the guide member 11 according to an embodiment of this disclosure. (See also...) Figure 2 and Figure 4The cross-sectional shape of the guide member 11 is consistent with the cross-sectional shape of the guide hole 123 inside the guide sleeve 121. Compared with the case where the cross-sectional shape of the guide member 11 is inconsistent with the cross-sectional shape of the guide hole 123, when the cross-sectional shape of the guide hole 123 is consistent with the cross-sectional shape of the guide member 11, the guide sleeve 121 can move more smoothly and stably under the guidance of the guide member 11.
[0048] Optionally, the guide member 11 has a circular cross-section. The guide sleeve 121 has a cross-section that is adapted to the guide member 11 in a superior arc shape. The superior arc shape means that the cross-section of the guide sleeve 121 is an arc shape larger than a semicircle. As a result, the relative and contacting area between the guide member 11 and the guide sleeve 121 is relatively large, and the width of the clearance notch 122 is relatively small. The guide member 11 is difficult to extend beyond the guide sleeve 121 through the clearance notch 122, which makes the limiting and guiding effect of the guide sleeve 121 on the floating limiting member 12 better, and helps to ensure that the floating limiting member 12 can be smoothly lifted upward without detaching from the guide member 11.
[0049] Optionally, see Figure 2 and Figure 3 The end of the part to be avoided 111 away from the guide member 11 is provided with a mounting base 112 for mounting on the external carrier 700, and the mounting base 112 forms a mounting hole 1121 through which a fastener for fastening to the external carrier 700 passes. For example, the fastener can be a bolt, which can pass through the mounting hole 1121 to install the mounting base 112 on the external carrier 700, thereby fixing the position of the guide member 11 and facilitating installation.
[0050] Optionally, see Figure 2The membrane module limiting device 100 further includes a locking member 13. The locking member 13 is detachably connected to the upper end of the floating limiting member 12 and the guide member 11, respectively, and is used to unlock and lock the movement of the floating limiting member 12 relative to the guide member 11. In other words, when the floating limiting member 12 is in the blocking position, the locking member 13 can lock the floating limiting member 12 to the guide member 11, thereby keeping the floating limiting member 12 in a blocking position that prevents the membrane module 600 from moving upward. When the membrane module 600 needs to be lifted for cleaning, the locking member 13 can release the locking state between the floating limiting member 12 and the guide member 11, allowing the floating limiting member 12 to be lifted away from the blocking position, thus no longer blocking the upward movement of the membrane module 600, and facilitating offline rinsing of the membrane module 600. For example, the locking member 13 may be a threaded member including a U-bolt, used to lock / unlock the movement of the floating limit member 12 relative to the guide member 11 by means of the U-bolt being sleeved on the outside of the guide member 11 and threadedly locked / unlocked to the floating limit member 12.
[0051] Optionally, the locking member 13 is always located on the water surface, so that relevant personnel above the water surface can release the locking state of the floating limit member 12 without underwater operation, making the operation convenient.
[0052] Optionally, the locking member 13 is located above each of the parts to be avoided 111. In this way, the locking state of the floating limiting member 12 can be released above each of the parts to be avoided 111, with less interference, more operating space, and convenient operation.
[0053] This disclosure also provides membrane devices, see [link / reference]. Figure 1 and Figure 3 The membrane device includes a membrane module limiting device 100 and a membrane module 600 as described in any of the examples above. The membrane module 600 is located below the floating limiting member 12. Thus, when the membrane module 600 is submerged below the wastewater level 900 for wastewater treatment, the floating limiting member 12 can limit the membrane module 600, thereby restricting its upward movement during normal operation. When the floating limiting member 12 moves upward away from its original position, creating vertical space for the membrane module 600 to be lifted upward, the movement distance of the floating limiting member 12 is unrestricted and difficult to interfere with, which helps ensure the smooth and stable movement of the floating limiting member 12.
[0054] Optionally, the membrane device further includes a lifting device 800. The lifting device 800 is fixed to the upper surface of the membrane module 600. Thus, when the floating limit member 12 moves to a predetermined position spaced above the membrane module 600, the hook of the lifting tool can be connected to the lifting device 800, thereby facilitating the upward lifting of the membrane module 600 using the lifting device 800, making the lifting of the membrane module 600 convenient.
[0055] Optionally, the lifting device 800 includes a plurality of lifting components 81. The plurality of lifting components 81 extend upward from the periphery towards the center and are fixedly connected to form a receiving portion 82 held at a certain height, such that the receiving portion 82 is located above the liquid level 900 of the liquid immersing the membrane module 600. One end of the plurality of lifting components 81 on the periphery forms a connection end 83 for connection to the membrane module 600. Thus, when the lifting tool lifts the membrane module 600 from the liquid for online cleaning, the lifting tool can directly lift the receiving portion 82 without draining the liquid to lower the liquid level 900. Therefore, the membrane module 600 can be lifted directly without lowering the liquid level 900, facilitating on-site lifting operations. Furthermore, the device has a simple structure, low cost, and is suitable for mass production.
[0056] Optionally, the lifting member 81 is made of rigid metal, and when there are four lifting members 81, every two lifting members 81 are connected to form a downward-opening arc-shaped lifting frame. The tops of two arc-shaped lifting frames are welded together to form the suspended part 82. Thus, the lifting device 800 is easy to manufacture, low in cost, and the suspended part 82 is less prone to sagging and deformation, and can always be maintained above the liquid level of 900.
[0057] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
