Description

Technical Field

[0001] This invention relates to the field of membrane cleaning technology, specifically to a degassing membrane cleaning device with a support structure. Background Technology

[0002] A degassing membrane is a gas-liquid separation device based on membrane separation technology, achieving high-efficiency degassing through a hollow fiber membrane structure. Its core principle is to utilize a hydrophobic microporous membrane that allows gas molecules to pass through while blocking liquid and solute molecules. Gas migration to the outside of the membrane is driven by vacuum or pressure difference. The degassing membrane contains numerous hollow fibers, with micropores (0.01 × 0.2 micrometers) on the fiber walls allowing only gas molecules to pass through. Under pressure, liquid flows through the inner side of the hollow fibers, while the outer side is negatively pressured by a vacuum or purge gas (such as high-purity nitrogen). This negative pressure forces dissolved gases in the water (such as oxygen, carbon dioxide, and ammonia nitrogen) to migrate through the micropores to the outside and be extracted. Because the degassing membrane has a hard outer shell, there are two interfaces at each end of the degassing membrane (e.g., Figure 5 As indicated by arrow A, the interior of the degassing membrane cannot be cleaned conventionally. Therefore, existing cleaning methods involve immersing the membrane in a cleaning solution followed by rinsing. This method is not only ineffective but also time-consuming and labor-intensive. To address this, we propose a degassing membrane cleaning device with a supporting structure. Summary of the Invention

[0003] This invention provides a degassing membrane cleaning device with a support structure, which has the advantage of thoroughly cleaning the inside of the degassing membrane and solves the problems mentioned in the background art.

[0004] The technical solution of this invention is implemented as follows: A degassing membrane cleaning device with a support structure is designed, including a cleaning tank. The cleaning tank contains at least one support structure for supporting the degassing membrane, and the support structure includes a placement seat. This invention also includes plugs corresponding to the number of interfaces of the degassing membrane. The plugs are detachably installed within the interfaces. Each plug has a coaxially arranged vibration transmission rod that extends from the interface into the interior of the degassing membrane. One end of both the vibration transmission rod and the plug is mounted on an ultrasonic generator. The vibration emitted by the ultrasonic generator is transmitted to the interior of the degassing membrane through the vibration transmission rod. The plug has an outlet and an inlet. The inlet is connected to a delivery device, which delivers cleaning fluid into the degassing membrane. The vibration transmission rod drives the cleaning fluid to generate ultrasonic vibrations.

[0005] Preferably, the placement seat is mounted on the bottom of the cleaning tank via a bracket.

[0006] Preferably, the placement seat is provided with a fastening device for fixing the degassing membrane. The fastening device includes at least one arc-shaped retainer that is engaged with the degassing membrane and is detachably connected to the placement seat.

[0007] Preferably, the top of the placement seat is provided with a placement groove whose shape matches the degassing membrane, the degassing membrane is placed in the placement groove, and all the interfaces of the degassing membrane are located outside the placement seat.

[0008] Preferably, the ultrasonic generator includes an amplitude transformer, a transducer is installed at one end of the amplitude transformer, and the other end of the amplitude transformer is coaxially connected to a vibration transmission rod. A plug is detachably installed at the end of the amplitude transformer. The amplitude transformer is installed in a mounting base. At least one support shaft is vertically inserted through the mounting base. One end of the support shaft is fixed to a bracket. A locking knob for fixing the mounting base is threaded on the support shaft. Turning the locking knob can move the mounting base closer to the degassing membrane, so that the plug is pressed into the interface with a certain pressure.

[0009] Preferably, both the amplitude rod and the plug are provided with flanges at opposite ends, and the two flanges are connected by fasteners.

[0010] Preferably, the infusion device includes at least one infusion pump, which is connected to the inlet via a pipe.

[0011] Preferably, the cleaning box is positioned above the support cabinet.

[0012] Preferably, a liquid collection tank is provided on one side of the support cabinet, and the liquid collection tank is connected to the infusion pump through a pipeline.

[0013] Compared with existing technologies, this invention, in its use, firstly, fixes the degassed membrane to be cleaned on the placement base, then inserts the mounting base onto the support shaft, and tightens the fasteners to insert the plugs into each interface. Afterwards, the infusion pump can be started to deliver cleaning fluid into each interface. When the transducer is turned on, it drives the vibration rod to perform ultrasonic vibration. The ultrasonic vibration acts on the inside of the membrane, resulting in rapid cleaning. The dirt removed by the cleaning process flows out along with the cleaning fluid from the outlet, thoroughly cleaning the inside of the membrane. Furthermore, it is simple to operate and convenient to use. Attached Figure Description

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 6 The present invention provides a technical solution: a degassing membrane cleaning device with a support structure, comprising a cleaning tank 2, wherein the cleaning tank 2 is provided with at least one device for supporting the degassing membrane (e.g., Figure 5 and Figure 6 The supporting structure (indicated by arrow B), such as Figure 1 As shown, the support structure includes a placement seat 12, which is installed at the bottom of the cleaning tank 2 via a bracket 3, so that there is a certain distance between the placement seat 12 and the bottom of the cleaning tank 2; The cleaning tank 2 is located above the support cabinet 1. A liquid collection tank 13 is provided on one side of the support cabinet 1. The liquid collection tank 13 is used to store the cleaning solution. A drain valve is provided at the bottom side of the cleaning tank 2. When there is sewage in the cleaning tank 2, it can be discharged through the drain valve.

[0024] like Figure 5 As shown, actual degassing membranes typically have four interfaces (e.g., Figure 5(As indicated by arrow A), and a placement groove 16 with a shape matching the degassing membrane is provided on the top of the placement base 12. The degassing membrane is placed in the placement groove 16, and at this time, all interfaces of the degassing membrane are located outside the placement base 12. In order to ensure that the degassing membrane is stably located in the placement base 12, a fastening device for fixing the degassing membrane is provided on the placement base 12. The fastening device includes at least one arc-shaped retainer 15, which is engaged with the degassing membrane. The retainer 15 is detachably connected to the placement base 12. Both ends of the retainer 15 are fastened to the placement base 12 by latches, or one end of the retainer 15 is rotatably connected to the placement base 12, and the other end is connected to the placement base 12 by latches. The retainer 15 can press the degassing membrane tightly onto the placement base 12 without loosening, and the shape of the degassing membrane matches the placement groove 16. When the degassing membrane is placed in the placement groove 16, it is positioned. In this application, each interface of the degassing membrane is detachably provided with a plug 10, such as Figure 1 As shown, a vibration transmission rod 11 is coaxially provided in each plug 10. There is a gap between the vibration transmission rod 11 and the inside of the plug 10, that is, the inner diameter of the plug 10 is larger than the diameter of the vibration transmission rod 11. The vibration transmission rod 11 is a metal rod, and the vibration transmission rod 11 extends from the interface into the degassing membrane. It should be noted that the interface of the degassing membrane is connected to its interior, so the vibration transmission rod 11 can extend from the interface into its interior. Both the vibration transmission rod 11 and the plug 10 are mounted on the ultrasonic generator, such as... Figure 1 and Figure 2 As shown, the ultrasonic generator includes an amplitude transformer 7, a transducer 6 is installed at one end of the amplitude transformer 7, and the other end of the amplitude transformer 7 is coaxially connected to the vibration transmission rod 11. That is, the amplitude transformer 7 and the vibration transmission rod 11 are an integral structure. When the transducer 6 is working, the vibration it generates is amplified by the amplitude transformer 7 and directly acts on the vibration transmission rod 11, causing the vibration transmission rod 11 to generate ultrasonic vibration. That is, the vibration emitted by the ultrasonic generator is transmitted to the degassing membrane through the vibration transmission rod 11. like Figure 1 As shown, the plug 10 is detachably mounted on the end of the luffing rod 7. Flanges are provided at the opposite ends of both the luffing rod 7 and the plug 10, and the two flanges are connected by fasteners. This facilitates the disassembly and installation of the plug 10. The plug 10 has a rubber pad on its surface and a tapered end. When fixing the luffing rod 7, it needs to be installed inside the mounting base 8, and a rubber seat is provided between the mounting base 8 and the luffing rod 7 to prevent the vibration of the luffing rod 7 from being transmitted to the mounting base 8. To facilitate the disassembly and installation of the mounting base 8, at least one support shaft 4 is vertically inserted through the mounting base 8, such as... Figure 2 and Figure 5As shown, each set of support shafts 4 consists of two shafts. One end of the support shaft 4 is fixed to the bracket 3. The support shaft 4 is threaded with a mounting seat 8 that is fixed to the locking knob 5. Turning the locking knob 5 can move the mounting seat 8 toward the degassing membrane, so that the plug 10 is placed in the interface with a certain pressure, so that the plug 10 and each interface are sealed.

[0025] Furthermore, in actual use, the cleaning fluid needs to be introduced into the degassing membrane to fill the entire interior, allowing the cleaning fluid to vibrate ultrasonically along with the vibration rod 11, thus cleaning the interior of the membrane. Therefore, the plug 10 is equipped with an outlet 9 and an inlet 14. The inlet 14 is connected to a delivery device, which includes at least one delivery pump 17. The delivery pump 17 is connected to the inlet 14 via a pipe. In practical applications, multiple inlets 14 can be connected to a single delivery pump 17 via pipes, or each inlet 14 can be connected to a separate delivery pump 17. The delivery pump 17 is installed inside the support cabinet 1 and is connected to the collection tank 13 via a pipe, allowing the delivery device to send the cleaning fluid into the degassing membrane, and the vibration rod 11 to drive the cleaning fluid to vibrate ultrasonically, thus cleaning the interior of the membrane.

[0026] Based on the above embodiments, when using the degassing membrane cleaning device proposed in this application, firstly, the degassing membrane to be cleaned is placed in the placement seat 12 and positioned, and then fixed by the retaining seat 15. Before placing the degassing membrane, each plug 10 is separated from the interface, and the state at this time is as follows: Figure 5 As shown, there is no plug 10 around the interface; Next, hold the mounting base 8 and align the hole on the mounting base 8 with the support shaft 4. Insert the mounting base 8 into the support shaft 4, and then thread a fastener onto the support shaft 4. Tighten the fastener to move the mounting base 8 toward the membrane. Since the plug 10 corresponds to the position of each structure, the plug 10 can be accurately inserted into each interface. Under the action of the pushing force, the plug 10 and the interface are squeezed together, so that the two are completely sealed. Next, once the plug 10 and the interface are installed, the infusion pump 17 can be started to deliver cleaning fluid into each interface. When the cleaning fluid flows out from each outlet 9, the transducer 6 can be turned on. The transducer 6 drives the vibration rod 11 to perform ultrasonic vibration. The ultrasonic vibration acts on the inside of the membrane, and the inside of the membrane is quickly cleaned. The dirt that is washed off will flow out from the outlet 9 along with the cleaning fluid. When the outflowing cleaning fluid is clean, it proves that the inside of the membrane has been tilted. Finally, after cleaning is complete, remove each mounting bracket 8, then open the card holder 15 to remove the cleaned membrane, and replace it with a new membrane to be cleaned and continue cleaning.

[0027] Based on the above embodiments, further optimizations can be made, such as... Figure 1 and Figure 2 As shown by the arrow, the wastewater will flow out from the outlet. A conduit can be installed on the top of each outlet 9. The conduit is a flexible tube with its free end placed at the bottom of the cleaning tank 2, so that the wastewater stays directly at the bottom of the cleaning tank and avoids wastewater splashing.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
