Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically a spiral-type transparent end cap ultrafiltration machine that does not require disassembly of the tube. Background Technology

[0002] Ultrafiltration machines, as highly efficient water treatment equipment, are widely used in the water purification field. Their core component, the ultrafiltration membrane fiber, removes impurities from water through physical sieving. However, existing ultrafiltration machines generally suffer from the following problems:

[0003] Insufficient cleaning effect: Traditional ultrafiltration machines mostly adopt a straight-through water flow design, with a single water flow direction, resulting in weak scouring force on the surface of the ultrafiltration membrane fibers. After long-term operation, impurities easily accumulate on the surface of the membrane fibers, forming a fouling layer, which not only reduces the filtration flux but also increases the transmembrane pressure difference, leading to increased energy consumption.

[0004] Cumbersome maintenance: Most of the filter elements in existing ultrafiltration machines adopt a fixed installation structure. When replacing or cleaning them, it is necessary to disassemble the inlet and outlet water pipes or even the entire equipment shell. The operation process is complicated and is prone to leakage at the interface.

[0005] In addition, most equipment relies on a single rubber ring for sealing, which is prone to aging and failure under long-term water pressure fluctuations and temperature changes, resulting in decreased sealing performance and the risk of leakage.

[0006] Therefore, there is an urgent need for an ultrafiltration machine with high efficiency self-cleaning, modular disassembly and assembly, and double sealing to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this invention is to provide a spiral-type transparent end cap ultrafiltration machine that does not require disassembly of the tube, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a spiral-type transparent end-capped ultrafiltration machine without disassembly, comprising a cylindrical body, an end cap integrally provided at the top of the cylindrical body, a purified water outlet pipe provided at the top of the end cap, an ultrafiltration filter element installed inside the cylindrical body, the top of the ultrafiltration filter element being detachably and sealed to the end cap, a water inlet pipe provided at the upper end of the side wall of the cylindrical body, a first sewage discharge pipe provided at the lower end of the side wall of the cylindrical body, a spiral guide strip provided inside the cylindrical body, the spiral guide strip being axially arranged between the water inlet pipe and the first sewage discharge pipe and sleeved on the outside of the ultrafiltration filter element, the inner ends of the water inlet pipe and the first sewage discharge pipe being bent at a 90-degree right angle, and a detachably fitted bottom seal provided at the bottom of the cylindrical body.

[0009] The present invention is further configured such that the ultrafiltration filter element includes a mounting base, and a first sealing structure and a second sealing structure are provided between the mounting base and the end cap. Multiple sets of ultrafiltration membrane fibers are evenly arranged on the mounting base, and the top end of the ultrafiltration membrane fibers is connected to the top of the mounting base. The mounting base enables the ultrafiltration membrane fibers to be stably installed inside the cylinder, thereby achieving convenient and quick installation of the entire ultrafiltration filter element.

[0010] The present invention is further configured such that the first sealing structure includes a limiting edge, the limiting edge being located inside the end cap and used to restrict the upward movement of the mounting base, and a sealing gasket being provided at one end of the limiting edge near the mounting base. Through the cooperation of the limiting edge and the sealing gasket, the ultrafiltration filter element can be stably and accurately limited during installation, and at the same time, a primary seal can be achieved between the mounting base and the end cap during installation.

[0011] The present invention is further configured such that the second sealing structure includes a first sealing ring and a second sealing ring. The first sealing ring is fixed on the periphery of the mounting base, and the second sealing ring is disposed on the inner wall of the end cap and located on the side of the end cap away from the purified water outlet pipe. The first sealing ring and the second sealing ring can squeeze and engage with each other. When the mounting base carrying the ultrafiltration membrane fiber is inserted into the end cap, the first sealing ring and the second sealing ring will squeeze and engage with each other. In this way, the connection sealing between the mounting base and the end cap can be improved, thereby strengthening the connection sealing of the ultrafiltration filter element after installation. Together with the sealing gasket, a double seal is achieved to avoid leakage during the filtration process.

[0012] The present invention is further configured such that a disassembly center tube is provided in the middle of the mounting base, the disassembly center tube extends downward to below the ultrafiltration membrane fiber, and a disassembly center frame is provided thereon. The disassembly center tube is a solid tube. In this way, when it is necessary to disassemble the ultrafiltration filter element, it is not necessary to disassemble the water inlet pipe and the first sewage outlet pipe. The disassembly center frame can be pulled outward directly. With the cooperation of the disassembly center tube, the mounting base carrying the ultrafiltration membrane fiber can be pulled outward directly, realizing the quick and convenient disassembly of the ultrafiltration filter element.

[0013] The present invention is further configured such that a threaded section is provided at the bottom end of the cylinder body, and the sealing thread is screwed onto the threaded section. The threaded section enables the sealing to be quickly installed and fixed at the bottom of the cylinder body.

[0014] The present invention is further configured such that a pressing column is provided at the inner bottom end of the sealing bottom, and a pressing seat is installed at the top end of the pressing column via a bearing. The pressing seat is pressed and fixed on the disassembly center frame. After the sealing bottom is installed at the bottom end of the cylinder body, the pressing column can carry the pressing seat and press and fix it on the disassembly center frame. In this way, the mounting seat can be pressed and fixed at the limiting edge by the cooperation of the disassembly center frame and the disassembly center tube, thereby improving the installation stability and sealing of the ultrafiltration filter element inside the cylinder body and improving the filtration effect.

[0015] The present invention is further configured such that a connecting edge is provided at the top of the bottom seal, and a fixing edge is provided on the side wall of the cylinder body. The fixing edge is located below the first sewage pipe. A clamp is provided on the outer side of the fixing edge and the connecting edge. The connecting edge and the fixing edge are fixed and limited by the clamp. In this way, the installation stability of the bottom seal at the bottom of the cylinder body can be enhanced, and the bottom seal can be prevented from loosening due to vibration caused by water flow and other factors.

[0016] The present invention is further configured such that a second drain pipe is provided on the bottom of the sealed surface, and a sealing cap is provided at the bottom end of the second drain pipe. Preferably, the sealing cap is threaded and screwed onto the bottom end of the second drain pipe. In this way, when it is inconvenient to drain the sewage through the first drain pipe, the second drain pipe can be opened manually to achieve manual sewage discharge.

[0017] The present invention is further configured such that a valve is provided on the first sewage pipe, and the first sewage pipe is used to connect to sewage pipes such as sewers, so that when cleaning is required, the valve can be directly controlled to open, so that sewage can be discharged from the first sewage pipe to the sewage pipe.

[0018] The present invention is further provided with a wall-mounting bracket on the outer side of the cylinder body, and a fixing ear at both ends of the wall-mounting bracket, wherein a fixing hole is provided on the fixing ear.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. High-efficiency cleaning and filtration performance

[0021] This invention utilizes a synergistic design of a spiral guide strip, a 90-degree right-angle bend in the water inlet pipe, and a first drain pipe to create a vortex-like flow of water within the cylinder, significantly enhancing the flushing effect on the ultrafiltration membrane fiber surface. This dynamic flushing mode effectively removes attached impurities, preventing membrane fiber clogging. Combined with a dual drain pipe design (automatic and manual draining), it ensures thorough cleaning. The transparent head and bottom seals facilitate real-time observation of the internal condition, further optimizing maintenance efficiency, extending the lifespan of the ultrafiltration membrane fibers, and guaranteeing stable purified water output quality.

[0022] 2. Modular assembly and disassembly and optimized sealing

[0023] The ultrafiltration filter element features a detachable structure, allowing for quick installation and fixation through the disassembly of the central tube and clamping column, eliminating the need to disassemble external piping. A first sealing structure (limiting flange and sealing gasket) and a second sealing structure (double sealing ring engagement) form a double seal, effectively preventing leakage. The bottom seal is double-fixed via threaded connection and clamps, ensuring stability. This design significantly simplifies the filter element replacement process, reduces maintenance costs, and simultaneously improves the overall sealing performance and reliability of the equipment.

[0024] 3. In this utility model, the first drain pipe is equipped with a valve to support automatic draining, while the second drain pipe is equipped with a detachable sealing cap for easy manual draining, adapting to different scenario requirements. The spiral guide strip and symmetrical pipe opening design create a vortex water flow, which, combined with the dual drain channels, can efficiently remove deposited impurities. Furthermore, the transparent component design allows users to visually monitor the filter cartridge status and perform timely maintenance. This multi-functional integrated design significantly improves the practicality and adaptability of the equipment. Attached Figure Description

[0035] Please see Figures 1-7 As one implementation of the ultrafiltration filter element 4: the ultrafiltration filter element 4 includes a mounting base 9, and a first sealing structure and a second sealing structure are provided between the mounting base 9 and the end cap 2. Multiple sets of ultrafiltration membrane fibers 10 are evenly arranged on the mounting base 9, and the top end of the ultrafiltration membrane fiber 10 is connected to the top of the mounting base 9. The ultrafiltration membrane fiber 10 is stably installed inside the cylinder body 1 through the mounting base 9, thereby realizing the convenient and quick installation of the entire ultrafiltration filter element 4.

[0036] Please see Figures 1-7 As one embodiment of the first sealing structure: the first sealing structure includes a limiting edge 11, which is located inside the end cap 2 and is used to limit the upward movement of the mounting base 9. A sealing gasket 12 is provided at one end of the limiting edge 11 near the mounting base 9. The cooperation between the limiting edge 11 and the sealing gasket 12 can achieve stable and precise positioning of the ultrafiltration filter element 4 during installation, and at the same time, achieve primary sealing between the mounting base 9 and the end cap 2 during installation.

[0037] Please see Figures 1-7As one embodiment of the second sealing structure: the second sealing structure includes a first sealing ring 13 and a second sealing ring 14.

The first sealing ring 13 and the second sealing ring 14 can squeeze and engage with each other. When the mounting base 9 carrying the ultrafiltration membrane fiber 10 is inserted into the end cap 2, the first sealing ring 13 and the second sealing ring 14 will squeeze and engage with each other.

[0038] Please see Figures 1-7 As one embodiment of the mounting base 9: a disassembly center tube 15 is provided in the middle of the mounting base 9. The disassembly center tube 15 extends downward to the lower part of the ultrafiltration membrane fiber 10 and is provided with a disassembly center frame 16. The disassembly center tube 15 is a solid tube.

The disassembly center frame 16 can be pulled out directly. With the cooperation of the disassembly center tube 15, the mounting base 9 carrying the ultrafiltration membrane fiber 10 can be pulled out directly, realizing the quick and convenient disassembly of the ultrafiltration filter element 4. The disassembly center tube 15 is located in the central area of ​​the ultrafiltration membrane fiber 10 and does not affect the flow of raw water.

[0039] This utility model has a threaded section 17 at the bottom of the cylinder body 1, and the bottom seal 8 is screwed onto the threaded section 17. The threaded section 17 enables the bottom seal 8 to be quickly installed and fixed at the bottom of the cylinder body 1.

[0040] Please see Figures 1-7 As one implementation of the bottom seal 8: a pressing column 18 is provided at the bottom of the inner part of the bottom seal 8, and a pressing seat 19 is installed at the top of the pressing column 18 through a bearing. The pressing seat 19 is pressed and fixed on the disassembly center frame 16. After the bottom seal 8 is installed at the bottom of the cylinder body 1, the pressing column 18 can carry the pressing seat 19 and press and fix it on the disassembly center frame 16. In this way, the mounting seat 9 can be pressed and fixed at the limiting clip edge 11 by the cooperation of the disassembly center frame 16 and the disassembly center tube 15, which improves the installation stability and sealing of the ultrafiltration filter element 4 inside the cylinder body 1 and improves the filtration effect. Here, the bearing is used to realize the rotation of the pressing seat 19 and avoid friction between the pressing seat 19 and the disassembly center frame 16 during the rotation.

[0041] Please see Figures 1-7As one implementation of the bottom sealing 8: a connecting edge 20 is provided at the top of the bottom sealing 8, and a fixing edge 21 is provided on the side wall of the cylinder 1. The fixing edge 21 is located below the first sewage pipe 6. A clamp 22 is provided on the outer side of the fixing edge 21 and the connecting edge 20. The connecting edge 20 and the fixing edge 21 are fixed and connected by the clamp 22. In this way, the installation stability of the bottom sealing 8 at the bottom of the cylinder 1 can be enhanced, and the bottom sealing 8 can be prevented from vibrating and loosening due to factors such as water flow.

[0042] This utility model is equipped with a valve 24 on the first sewage pipe 6. The first sewage pipe 6 is used to connect to sewage pipes such as sewers. When cleaning is required, the valve 24 can be directly controlled to open, so that sewage can be automatically discharged from the first sewage pipe 6 to the sewage pipe.

[0043] The present invention provides a second drain pipe 23 on the bottom seal 8, and a sealing cap 25 is provided at the bottom end of the second drain pipe 23. Preferably, the sealing cap 25 is screwed into the bottom end of the second drain pipe 23 with a thread seal. In this way, when it is inconvenient to drain the sewage from the first drain pipe 6, the second drain pipe 23 can be opened manually to achieve manual sewage discharge.

[0044] This utility model provides a wall-mounting bracket 26 on the outer side of the cylindrical body 1. The wall-mounting bracket 26 has fixing ears 27 at both ends and fixing holes 28 on the fixing ears. By passing existing screws or other fasteners through the fixing holes 28 and connecting and fixing them to the wall surface, the fixing ears 27 are connected and fixed to the wall surface. Thus, the cylindrical body 1 is installed and fixed on the wall surface through the wall-mounting bracket 26.

[0045] In summary, the working principle and specific workflow of this utility model are as follows:

[0046] In use, the raw water is transported to the interior of the ultrafiltration machine cylinder 1 through the water inlet pipe 5;

[0047] In this process, particulate impurities in the raw water are intercepted on the outside of the ultrafiltration membrane fiber 10, while the filtered clean water penetrates into the interior of the ultrafiltration membrane fiber 10 and reaches the space above the mounting base 9 through the top, and is then discharged outward through the clean water outlet pipe 3, thereby achieving the purification of the raw water.

[0048] During the above process, both the first sewage pipe 6 and the second sewage pipe 23 are in a closed state;

[0049] Furthermore, this invention allows raw water to permeate from the outside to the inside of the ultrafiltration membrane fiber 10, avoiding the blockage of the internal channels of the ultrafiltration membrane fiber 10 by impurities, and improving the convenience of cleaning the ultrafiltration membrane fiber 10.

[0050] In this utility model, both the bottom cover 8 and the top cover 2 are designed with transparent materials;

[0051] When it is necessary to clean the ultrafiltration membrane fiber 10, open the valve 24 on the first drain pipe 6. At this time, you can choose whether to close the clean water outlet pipe 3 as needed. It is preferable that the clean water outlet pipe 3 is in the closed state.

[0052] During this process, after the raw water enters the interior of the cylinder 1, it generates a vortex rotation under the action of the spiral guide bar 7, which impacts the surface of the ultrafiltration membrane fiber 10.

[0053] This utility model designs a set of 90-degree right-angle bend water inlet pipe 5 and first sewage outlet pipe 6 inside the cylinder body 1. The two pipe openings are installed symmetrically at 180 degrees. When the sewage generated during the cleaning of the ultrafiltration membrane fiber 10 is discharged, it is flushed in a vortex rotation with the spiral guide strip 7, which significantly improves the cleaning effect of the ultrafiltration filter element 4. The impurities and sewage that are flushed down are discharged through the first sewage outlet pipe 6.

[0054] When automatic cleaning is not sufficient, the ultrafiltration filter element 4 can be disassembled and the ultrafiltration membrane fiber 10 can be cleaned manually to improve the service life of the ultrafiltration machine.

[0055] When installing the ultrafiltration filter element 4, the ultrafiltration filter element 4 can be directly pushed into the cylinder body 1 by hand disassembling the center frame 16 and sealed and fixed in the end cap 2, so that the mounting seat 9 is pressed and adhered to the limiting clip 11 and the sealing gasket 12, and at the same time, the first sealing ring 13 and the second sealing ring 14 are pressed and engaged with each other.

[0056] Afterwards, screw the bottom sealing 8 thread onto the threaded section 17 at the bottom of the cylinder 1. After screwing, the clamping seat 19 will be clamped and fixed on the disassembly center frame 16 with the cooperation of the clamping column 18, thereby enhancing the installation sealing and stability of the ultrafiltration filter element 4.

[0057] Then, the fixing edge 21 and the connecting edge 20 are locked and fixed by clamp 22, thereby achieving stable installation of the bottom seal 8 at the bottom of the cylinder body 1;

[0058] With this invention, when disassembling and cleaning the ultrafiltration filter element 4, the bottom seal 8 can be removed, and the ultrafiltration filter element 4 can be directly pulled out from the bottom of the cylinder 1, which is convenient to operate and flexible to replace.
