Description

Technical Field

[0001] This application relates to an ultrafiltration membrane core removal system, belonging to the field of water treatment technology. Background Technology

[0002] With the development of membrane materials and technologies, membrane separation technology, as a novel water treatment technology, is widely used in wastewater treatment fields such as biology, chemical industry, pharmaceuticals, food, and municipal engineering. Ultrafiltration membranes are microporous filtration membranes with uniform pore size specifications and a rated pore size range of less than 0.01 micrometers. They are commonly used in the separation, concentration, and purification of biological products, pharmaceutical products, and the food industry; they are also used in terminal treatment devices for blood processing, wastewater treatment, and ultrapure water preparation.

[0003] Ultrafiltration membranes are typically installed with separate membrane cartridges and housings. Because the housings have a longer lifespan, only the membrane cartridge needs replacement after a period of operation. Currently, when disassembling the membrane cartridges, the equipment consists of several interconnected cartridges. After removing the first cartridge, the remaining cartridges often break at the connection point, making them impossible to remove. They can only be pushed towards the outlet using a support rod, which is very inconvenient. Furthermore, with limited space, the support rod cannot be used, further hindering the removal of the membrane cartridges. Utility Model Content

[0004] To address the aforementioned issues, this application proposes an ultrafiltration membrane core removal system that allows access from the membrane core outlet to the end, and then removes the membrane core by pulling it back. This system requires minimal space and is very convenient to use.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An ultrafiltration membrane core removal system includes a winding device and a steel wire rope. The steel wire rope is threaded through the membrane core. One end of the steel wire rope is fixed to the winding device, and the other end is provided with a push-pull assembly that abuts against the membrane core. By pulling back the steel wire rope through the winding device, the push-pull assembly causes the membrane core to detach from the membrane shell.

[0007] Optionally, the push-pull assembly includes a latch and a flat iron, the flat iron being sleeved on the latch and abutting against the membrane core.

[0008] Optionally, the latch includes a sleeve and a threaded rod, one end of which is screwed to the inside of the sleeve, and the other end of which is provided with a cap nut and a hexagonal nut, with the hexagonal nut located between the cap nut and the sleeve.

[0009] Optionally, the sleeve is provided with threaded interfaces, which are distributed on opposite sides of the sleeve.

[0010] Optionally, the flat iron is provided with a through hole, and the threaded rod passes through the through hole to fasten the flat iron between the hexagonal nut and the sleeve.

[0011] Optionally, the ratio of the length of the flat iron to the inner diameter of the membrane shell is (0.7-0.9):1.

[0012] Optionally, the winding device includes a frame, within which a winding roller and a rotating rod are arranged in parallel, and the winding roller is kinetically connected to the rotating rod.

[0013] Optionally, both ends of the take-up roller and the rotating rod are fixed to the frame by bearing seats. A drive gear is connected to one side of the take-up roller, and a driven gear is connected to the same side of the rotating rod as the take-up roller. The drive gear and the driven gear are meshed together.

[0014] Optionally, the frame is provided with a rectangular opening and a receiving shell, the rectangular opening is connected to the receiving shell, the receiving shell is provided with a locking connector, and the rectangular opening is provided with a toggle rod, which drives the locking connector to slide back and forth within the receiving shell.

[0015] Optionally, a handle is connected to the side of the rotating rod near the driven gear, and the handle is located on the outside of the frame.

[0016] The beneficial effects that this application may produce include, but are not limited to:

[0017] The ultrafiltration membrane core removal system provided in this application, by incorporating a winding device, steel wire rope, and push-pull assembly, allows for the rapid removal of the membrane core from the membrane housing, eliminating the need for support rods. This not only reduces the equipment's footprint but also improves ease of use, safety, and efficiency. The locking mechanism securely connects the flat iron to the steel wire rope, ensuring stable force transmission during rope pullback and facilitating smooth membrane core removal. The rotating rod provides efficient and stable power transmission to the winding roller, resulting in smoother and more precise wire rope winding and unwinding. When it is necessary to secure the driven gear, a lever extends the locking connector from the housing, inserting the end of the connector away from the housing into the tooth spacing of the driven gear. To release the lock, the lever retracts the locking connector back into the housing. This ultrafiltration membrane core removal system is simple in structure, flexible and convenient to use, requires minimal space, and is suitable for widespread application.

[0032] Reference Figure 1-4 This application introduces an ultrafiltration membrane core removal system.

[0033] The ultrafiltration membrane core removal system according to this embodiment includes a winding device and a steel wire rope 1. The steel wire rope 1 is threaded through the membrane core 2. One end of the steel wire rope 1 is fixed to the winding device, and the other end is provided with a push-pull assembly that abuts against the membrane core 2. By pulling back the steel wire rope 1 through the winding device, the push-pull assembly causes the membrane core 2 to detach from the membrane shell 3. By pulling back the steel wire rope 1 through the winding device, the push-pull assembly applies force evenly, which can quickly remove the membrane core 2 from the membrane shell 3, avoiding the use of support rods. This not only reduces the space occupied by the equipment, but also improves the convenience, safety and efficiency of operation.

[0034] Specifically, the wire rope 1, the lock 5, and the flat iron 4 are all made of stainless steel, which makes them resistant to rust and corrosion, thus ensuring their mechanical properties and service life.

[0035] In one implementation, the push-pull assembly includes a latch 5 and a flat iron 4. The flat iron 4 is sleeved on the latch 5 and abuts against the membrane core 2. The latch 5 can firmly connect the flat iron 4 to the wire rope 1, ensuring that the flat iron 4 can stably transmit the tension when the wire rope 1 is pulled back, so that the membrane core 2 can be removed smoothly.

[0036] In one embodiment, the locking buckle 5 includes a sleeve 6 and a threaded rod 7. One end of the threaded rod 7 is screwed to the inside of the sleeve 6, and the other end of the threaded rod 7 is provided with a cap nut 8 and a hexagonal nut 9. The hexagonal nut 9 is located between the cap nut 8 and the sleeve 6. The double locking structure can significantly enhance the tensile force that the locking buckle 5 can withstand, effectively preventing loosening or falling off.

[0037] As one implementation, the sleeve 6 is provided with a screw interface 10, which is distributed on opposite sides of the sleeve 6; this allows a stable connection to be formed between the locking buckle 5 and the wire rope 1, as well as between the sleeve 6 and the threaded rod 7, reducing the risk of connection failure due to loosening.

[0038] In one implementation, a through hole 11 is provided on the flat iron 4, and the threaded rod 7 passes through the through hole 11 to fasten the flat iron 4 between the hexagonal nut 9 and the sleeve 6; ensuring that the flat iron 4 is in close contact with the membrane core 2, effectively transmitting the tension from the wire rope 1, thereby driving the membrane core 2 to detach from the membrane shell 3.

[0039] In one implementation, the length of the flat iron 4 is in the ratio of the inner diameter of the membrane shell 3 to (0.7-0.9):1, preferably 0.8:1; this can effectively apply force to push the membrane core 2 without damaging the membrane shell 3.

[0040] In one embodiment, the winding device includes a frame 12, in which a winding roller 13 and a rotating rod 14 are arranged in parallel. The winding roller 13 is connected to the rotating rod 14 in a transmission manner. The winding roller 13 can provide power to the winding roller 13 to realize the winding and unwinding of the wire rope 1.

[0041] In one implementation, both ends of the take-up roller 13 and the rotating rod 14 are fixed to the frame 12 by bearing seats, which makes the take-up roller 13 and the rotating rod 14 work more smoothly and reduces wear. One side of the take-up roller 13 is connected to a drive gear 15, and the same side of the rotating rod 14 is connected to a driven gear 16. The drive gear 15 and the driven gear 16 are meshed together. This facilitates the efficient and stable power transmission to the take-up roller 13, making the winding and unwinding of the wire rope 1 more stable and precise.

[0042] In one embodiment, the frame 12 is provided with a rectangular opening 17 and a receiving shell 18. The rectangular opening 17 is connected to the receiving shell 18. A snap-fit ​​connector 19 is provided in the receiving shell 18. A toggle lever 20 is provided in the rectangular opening 17. The toggle lever 20 drives the snap-fit ​​connector 19 to slide back and forth in the receiving shell 18. When it is necessary to fix the driven gear 16, the toggle lever 20 drives the snap-fit ​​connector 19 to extend out of the receiving shell 18, so that the end of the snap-fit ​​connector 19 away from the receiving shell 18 is inserted into the tooth pitch of the driven gear 16. When it is necessary to release the fixation, the toggle lever 20 can be used to retract the snap-fit ​​connector 19 into the receiving shell 18.

[0043] In this utility model, a limiting member 21 is movably connected to the frame 12. The limiting member 21 is rotated until it abuts against the snap-fit ​​connector 19. The limiting member 21 is locked and fixed by bolts and nuts, thereby locking the snap-fit ​​connector 19 and improving the reliability and safety of the winding device.

[0044] In one embodiment, a handle 22 is connected to the side of the rotating rod 14 near the driven gear 16, and the handle 22 is located on the outside of the frame 12; when it is necessary to rotate the rotating rod 14, the operator can directly hold the handle 22 to operate, which greatly improves the ease of use.

[0045] The working principle of the ultrafiltration membrane core removal system according to this embodiment is as follows:

[0046] Secure the locking buckle 5 to the end of the wire rope 1 away from the winding device, then pass the locking buckle 5 through the liquid channel in the middle of the membrane core 2 to the end, remove the hexagonal nut 9 and the cap nut 8, attach the flat iron 4 to the threaded rod 7, and then tighten the hexagonal nut 9 and the cap nut 8 to the threaded rod 7 in sequence, so that the flat iron 4 abuts against the membrane core 2. Then turn the handle 22 to pull the wire rope 1 back with the winding roller 13 and remove the membrane core 2 from the membrane shell 3.

[0047] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0048] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
