Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of water treatment, and in particular to a lifting type membrane module limiting device and a membrane device having the limiting device. Background Art
[0002] In the water treatment industry, membrane technology is becoming more and more popular, and membrane modules are being used more and more widely. When the membrane module is aerated in water, the impact of the aerated gas-water mixture on the membrane module makes it easy for the membrane module to float in the water, causing wear and tear, and also causing the connected pipes to be pulled or even damaged. Therefore, the membrane module generally has a limit device to prevent it from floating up, so that the membrane module will not float up. However, due to the product characteristics of the membrane module itself, the membrane module needs to be regularly lifted from the water and cleaned offline before being put back into the membrane pool filled with water.
[0003] In the above process, when the membrane module is lifted from the water, its limiting device, such as the clamp or bolt that fixes the membrane module to the fixed object, needs to be removed to release the limiting state of the membrane module. However, due to the product characteristics of the membrane module itself, the membrane module needs to be at a certain water surface depth to operate normally, so the limiting device of the membrane module is usually located below the water surface. Therefore, when removing the limiting device, it is often necessary to arrange in advance that the entire membrane pool stops producing water and then lower the water level in the membrane pool to below its limiting device, and then manually disassemble the limiting device, which makes it inconvenient to lift and clean the membrane module, which is time-consuming and labor-intensive, and makes the water production of the membrane module in the membrane pool easily affected, which will increase the water production pressure of the water plant and even cause environmental accidents.
[0004] In addition, since the membrane pool is in a closed state for a long time, a large amount of harmful gases are formed in the membrane pool, and there is a lot of garbage in the membrane pool, and the working environment is poor. Therefore, after the liquid level is lowered, when the operator directly enters the membrane pool to disassemble it, the operator's health is easily affected and accidents are prone to occur. Summary of the invention

[0029] Figure 1 Schematic diagram of the structure of the lifting type membrane module limiting device of the embodiment of the present disclosure when limiting the membrane module 900. Figure 1 The lifting type membrane module limiting device of the embodiment of the present disclosure includes at least one lifting type limiting assembly 100. The lifting type limiting assembly 100 is used to limit the membrane module 900 when the membrane module 900 treats the sewage in the membrane pool, so as to prevent the membrane module 900 from floating up during normal operation.
[0030] Figure 2 Schematic diagram of the structure of the lifting type membrane module limiter when the membrane module 900 is released from the limiter. Figure 2 The lifting limiting assembly 100 is also used to release the limiting of the membrane module 900 when the membrane module 900 needs to be lifted for cleaning, so that the membrane module 900 can be lifted smoothly.
[0031] Optionally, there are two lifting stopper assemblies 100, and the two lifting stopper assemblies 100 are arranged on opposite sides of the membrane module 900. Thus, the lifting stopper assemblies 100 can stop the membrane module 900 from opposite sides of the membrane module 900, and the stopping effect of the membrane module 900 is good. Of course, there can also be one lifting stopper assemblies 100, and one lifting stopper assemblies 100 can also stop the membrane module 900.
[0032] Each of the lifting and limiting assemblies 100 includes a fixing member 10 , a lifting and limiting member 20 and a locking member 30 .
[0033] The fixing member 10 is fixedly arranged adjacent to the membrane module 900. Therefore, when the membrane module 900 is arranged in a membrane pool filled with sewage to treat the sewage in the membrane pool, the fixing member 10 can be fixedly arranged in the membrane pool and located adjacent to the membrane module 900.
[0034] The lifting stopper 20 is connected to the fixing member 10 in a liftable manner, and the lifting and lowering stroke of the lifting stopper 20 includes a blocking position against the top of the membrane module 900. In other words, when the lifting stopper 20 is lifted and lowered relative to the fixing member 10, the lifting stopper 20 can be located at a blocking position where the lower end abuts against the top of the membrane module 900.
[0035] The locking member 30 is detachably connected to the upper end of the lifting limit member 20 and the fixing member 10, respectively, and is used to unlock and lock the lifting and lowering movement of the lifting limit member 20 relative to the fixing member 10, so that the lifting limit member 20 can be locked or disengaged from the blocking position.
[0036] Therefore, when the lifting limit member 20 is located in the blocking position and the locking member 30 is connected between the upper end of the lifting limit member 20 and the fixing member 10, the locking member 30 can lock the lifting limit member 20 to the fixing member 10, so that the lifting limit member 20 can be maintained in the blocking position, and then the lower end of the lifting limit member 20 can prevent the membrane module 900 from moving upward, thereby achieving the effect of limiting the floating of the membrane module 900.
[0037] When the membrane module 900 needs to be lifted for cleaning, the operator can disassemble the locking member 30 in an operating environment outside the liquid surface, such as on the bank of the membrane pool, so as to release the locking state between the lifting limit member 20 and the fixing member 10, so that the lifting limit member 20 can be lifted out of the blocking position and no longer blocks the upward movement of the membrane module 900. Therefore, the operator can operate the lifting device to lift the membrane module 900, so that the membrane module 900 is at least partially moved above the liquid surface of the membrane pool, thereby making it convenient for the lifted membrane module 900 to be flushed offline.
[0038] Optionally, the lifting limiter 20 is slidably matched with the fixing member 10 in the vertical direction. Therefore, when the lifting limiter 20 is lifted, the sliding match between the fixing member 10 and the lifting limiter 20 can guide the lifting limiter 20, so that the lifting limiter 20 can move vertically stably.
[0039] Figure 3 yes Figure 2 A magnified schematic diagram of part A in Figure 2. Figure 1and Figure 3 The fixing member 10 includes a fixing shaft 11 extending in the vertical direction. The lifting limit member 20 forms a guide sliding hole 2201 penetrating in the vertical direction, and the fixing shaft 11 is arranged in the guide sliding hole 2201. Thus, the lifting limit member 20 and the fixing member 10 realize a vertical sliding fit.
[0040] It is understandable that the sliding cooperation manner between the fixed shaft 11 and the lifting limit member 20 includes but is not limited to this. For example, the fixed shaft 11 and the lifting limit member 20 can also be slidably cooperated through a sliding groove and a protrusion.
[0041] Optionally, the fixed arm 12 is disposed on the fixed shaft 11 and is located in a sliding path of the lifting limit member 20 to limit the lifting limit member 20 .
[0042] Therefore, when the lifting limit member 20 moves to a certain height, the fixed arm 12 can limit the lifting limit member 20 , thereby preventing the lifting limit member 20 from moving upward, and further preventing the lifting limit member 20 from separating from the fixed shaft 11 .
[0043] Optionally, a blocking member 23 extending in the transverse direction is provided at the lower end of the lifting limit member 20, which is used to abut against the top of the membrane module 900. Therefore, when the blocking member 23 blocks the membrane module 900 from floating up, the contact area between the lifting limit member 20 and the membrane module 900 is large, so that the blocking member 23 is easy to press the membrane module 900, so that the lifting limit member 20 has a good limiting and blocking effect.
[0044] Optionally, the lifting limiter 20 includes a lifting shaft 21 and at least one guide frame 22. The lifting shaft 21 extends vertically. The guide frame 22 is disposed on the lifting shaft 21 and forms the guide sliding hole 2201.
[0045] Optionally, there are a plurality of guide frames 22, and the plurality of guide frames 22 are arranged at intervals along the vertical direction on the lifting shaft 21. Specifically, there are two guide frames 22, and the two guide frames 22 are arranged at intervals along the vertical direction on the lifting shaft 21.
[0046] Optionally, each of the guide frames 22 includes a first guide plate 221, a second guide plate 222 and a detachable part 223. The second guide plate 222 is spaced apart from the first guide plate 221 on the lifting shaft 21. The detachable part 223 detachably crosses the first guide plate 221 and the second guide plate 222, respectively, so as to form the guide slide hole 2201 between the first guide plate 221, the second guide plate 222 and the detachable part 223. Thus, when it is necessary to fully ensure the upward movement space of the membrane module 900, the lifting limiter 20 can be removed. Specifically, the operator can first lift the lifting limiter 20 out of the liquid surface for a distance, remove the detachable part 223 outside the liquid surface, and then remove the lifting limiter 20 from the fixed shaft 11, thereby completely removing the lifting limiter 20 from the fixed part 10.
[0047] In a specific example, the detachable member 223 includes a through screw that detachably crosses the first guide plate 221 and the second guide plate 222 .
[0048] Figure 4 yes Figure 1 This is an enlarged schematic diagram of part B in Figure 2. Figure 2 and Figure 4 The locking member 30 is provided on the lifting limit member 20 and forms a hoop hole with adjustable size for hooping the fixing member 11. Thus, by disassembling and adjusting the size of the hoop hole of the locking member 30, the fixing member can be tightened or released, so that the lifting limit member 20 is locked or unlocked on the fixing member 10, and locking or releasing is convenient.
[0049] The locking member 30 includes a locking screw. Thus, when the locking screw is connected to the upper end of the lifting limit member 20 and the fixing member 10, the lifting limit member 20 is locked to the fixing member 10. When the locking screw is removed from the lifting limit member 20 and the fixing member 10, the lifting limit member 20 is unlocked from the fixing member 10. The locking screw is easy to disassemble and assemble, has low cost and is easy to maintain.
[0050] Optionally, the locking screw is configured as a U-shaped screw. Specifically, the locking screw includes a U-shaped bolt 31, a first nut 32, and a second nut 33. The U-shaped bolt 31 is sleeved on the outside of the fixing member 10 and passes through the lifting limiter 20. The first nut 32 and the second nut 33 are threadedly engaged with the passing portion of the U-shaped bolt 31 to lock the lifting limiter 20 to the fixing member 10.
[0051] It is worth mentioning that since the locking member 30 is arranged at the upper end of the lifting limit member 20 and is not directly connected to or in contact with the membrane module 900, when the membrane module 900 is below the liquid level, the locking member 30 can be above the liquid level instead of being below the liquid level. Therefore, the locking member 30 can also be disassembled and assembled above the liquid level without lowering the liquid level.
[0052] Therefore, the lifting type membrane module limiting device of the embodiment of the present disclosure allows the membrane module 900 to be lifted and cleaned without lowering the liquid level, which is conducive to efficient cleaning of the membrane module 900.
[0053] See also Figure 1 The embodiment of the present disclosure also provides a membrane device, which includes the lifting type membrane module limiting device as described above and the membrane module 900.
[0054] Therefore, when the membrane module 900 is immersed in sewage to treat sewage, the lifting limiter 20 can limit the membrane module 900 when locked by the locking member 30, thereby limiting the floating movement of the membrane module 900 in normal operation, avoiding wear of the membrane module 900 and pulling damage to the pipeline connected to the membrane module 900.
[0055] When the membrane module 900 needs to be lifted upward to at least partially remove the sewage for cleaning, the operator can first remove the locking member 30 located outside the sewage, so that the lifting limit member 20 is lifted out of the original position, and a vertical space for the membrane module 900 to be lifted upward is avoided for the membrane module 900, so that the membrane module 900 can be moved upward. As a result, the lifting of the membrane module 900 will no longer be blocked, and the membrane module 900 can be smoothly lifted and cleaned.
[0056] Therefore, the limiting device of the lifting membrane module 900 of the embodiment of the present disclosure can release the limiting state of the membrane module 900 without lowering the liquid level and without underwater operation, so that the membrane module 900 can be lifted for cleaning, which is conducive to efficient cleaning of the membrane module 900.
[0057] Optionally, at least one sliding recessed hole 901 with a side opening is formed on the side of the membrane module 900, and the fixing member 10 extends vertically and is disposed in the sliding recessed hole 901. Specifically, the membrane module 900 forms a plurality of the sliding recessed holes 901, and the plurality of the sliding recessed holes 901 are arranged at intervals along the vertical direction, and the fixing member 10 is disposed in the plurality of the sliding recessed holes 901.
[0058] Therefore, when the membrane module 900 is hoisted, the fixing member 10 can guide and limit the hoisted membrane module 900, thereby limiting the floating of the membrane module 900 in the horizontal direction during the hoisting process, and ensuring smooth hoisting of the membrane module 900.
[0059] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been demonstrated and explained in the embodiments, and the embodiments of the present disclosure may be deformed or modified in any way without departing from the principles.
