Description

Technical Field

[0001] This utility model relates to the field of tubular membrane technology, and more specifically, to a tubular membrane with enhanced core limiting support. Background Technology

[0002] Tubular membranes are tubular microfiltration membrane products that operate in a low-pressure, cross-flow manner. They are used to retain and separate suspended solids from a feed solution. Some existing organic tubular membrane structures lack a fixed support frame in the middle section of the membrane core length, while others have a fixed support frame but lack limiting and fixing measures. This causes the tubular membrane to deform and sag after a period of operation, or the fixed support frame to shift after long-term operation and backflushing, resulting in the membrane core twisting and deforming, or even membrane core rupture. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a tubular membrane with enhanced core limiting support, which has the advantage of being less prone to twisting and deformation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tubular membrane with enhanced membrane core limiting support, comprising a PVC membrane shell, a groove is provided inside the PVC membrane shell, a slider is slidably connected inside the groove, a fixed support frame is fixedly installed at the end of the slider away from the groove, an installation hole is provided inside the fixed support frame, an organic tubular membrane core is inserted into the installation hole, a water passage hole is provided inside the fixed support frame, and a water outlet is fixedly installed on the outside of the PVC membrane shell.

[0005] As a preferred embodiment of this utility model, a fixed limiting rod is inserted into the mounting hole, and the fixed support frame and the fixed limiting rod are fixed with glue. End sealing panels are fixedly installed on both the left and right sides of the PVC membrane shell, and a guide tube is fixedly installed inside the end sealing panel. The guide tube is located inside the organic tubular membrane core.

[0006] As a preferred embodiment of this utility model, there are three fixed support frames, all of which are located inside the PVC membrane shell. The fixed support frames are circular in shape. There are multiple mounting holes, which are located inside the three fixed support frames respectively. There are multiple organic tubular membrane cores, which are all inserted into the multiple mounting holes.

[0007] As a preferred embodiment of this utility model, there are four sliding grooves, all of which are located on the outside of the three fixed support frames. There are multiple sliders, which are respectively fixedly connected to the three fixed support frames.

[0008] As a preferred embodiment of this utility model, there are multiple water passage holes, which are located inside the three fixed support frames, and the diameter of the multiple water passage holes is smaller than the diameter of the mounting hole.

[0009] As a preferred embodiment of this utility model, there are two end-sealing panels, which are located on the left and right sides of the PVC film shell respectively. There are two fixing limit rods, which are fixedly connected to the two end-sealing panels respectively. There are multiple guide tubes, which are fixedly connected to the two end-sealing panels respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features an installation hole inside a fixed support frame, into which an organic tubular membrane core is inserted. Both the fixed support frame and the organic tubular membrane core are located inside the PVC membrane shell. When the device is operating normally, the fixed support frame internally limits and supports the organic tubular membrane core, preventing it from twisting or deforming even after prolonged operation, thus ensuring the overall stability of the device. Furthermore, since the fixed support frame is connected to a fixed limiting rod, and the two are fixed with adhesive, the fixed support frame is positioned after installation, preventing displacement due to rapid water flow and ensuring its stability.

[0012] 2. This utility model features a sliding groove inside the PVC membrane shell, with a slider slidably connected inside the groove and fixedly connected to a fixed support frame. After prolonged operation, the organic tubular membrane core may become clogged due to impurities. In this case, the end-sealing panel can be removed, and the fixed support frame can be disassembled via the sliding action of the slider and the groove, thereby disassembling the organic tubular membrane core. This facilitates cleaning and unblocking of the organic tubular membrane core, improving cleaning efficiency. Simultaneously, a guide tube is fixedly installed on the side of the end-sealing panel near the organic tubular membrane core. The diameter of the guide tube is smaller than the diameter of the organic tubular membrane core, and the guide tube is located inside the organic tubular membrane core. When the liquid to be filtered enters the PVC membrane shell through the end-sealing panel, the multiple guide tubes act as guides, allowing the liquid to smoothly enter the multiple organic tubular membrane cores, facilitating permeation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides a tubular membrane with enhanced membrane core limiting support, including a PVC membrane shell 1. The interior of the PVC membrane shell 1 has a groove 2. A slider 3 is slidably connected inside the groove 2. A fixed support frame 4 is fixedly installed at the end of the slider 3 away from the groove 2. The fixed support frame 4 has an installation hole 5 inside. An organic tubular membrane core 6 is inserted into the installation hole 5. A water passage hole 7 is opened inside the fixed support frame 4. A water outlet 11 is fixedly installed on the outside of the PVC membrane shell 1.

[0021] The surface of the organic tubular membrane core 6 has multiple permeation pores, the main function of which is to filter the water inside, so that the filtered water permeates out from the outside of the organic tubular membrane core 6, while the impurities contained in the water are discharged outward. At this time, the filtered water is discharged into the designated pipe through the outlet 11, thus achieving the filtration effect.

[0022] The mounting hole 5 is fitted with a fixed limiting rod 8. The fixed support frame 4 and the fixed limiting rod 8 are fixed with glue. End sealing panels 9 are fixedly installed on both the left and right sides of the PVC membrane shell 1. A guide tube 10 is fixedly installed inside the end sealing panel 9. The guide tube 10 is located inside the organic tubular membrane core 6.

[0023] The fixed limit rod 8 is fixed to the fixed support frame 4 with glue, so as to fix and limit the fixed support frame 4 after the fixed support frame 4 is installed, and prevent displacement when the fixed support frame 4 is backwashed.

[0024] There are three fixed support frames 4, all of which are located inside the PVC membrane shell 1. The fixed support frames 4 are circular. There are multiple mounting holes 5, which are located inside the three fixed support frames 4 respectively. There are multiple organic tubular membrane cores 6, which are all inserted into the multiple mounting holes 5.

[0025] The main function of the three fixed support frames 4 is to support the multiple organic tubular membrane cores 6, preventing bending and deformation that may occur during long-term normal use of the device.

[0026] There are four slide grooves 2, all of which are located on the outside of the three fixed support frames 4. There are multiple sliders 3, which are fixedly connected to the three fixed support frames 4 respectively.

[0027] The main function of the multiple sliders 3 is to allow the three fixed support frames 4 to slide through the multiple sliders 3 and the four sliding grooves 2 when multiple fixed support frames 4 need to be installed, thereby facilitating the installation.

[0028] There are multiple water passage holes 7, which are located inside the three fixed support frames 4 respectively, and the diameter of the multiple water passage holes 7 is smaller than the diameter of the mounting hole 5.

[0029] The main function of the multiple water passages 7 is to prevent the fixed support frame 4 from clogging the water during normal water seepage, thereby improving the efficiency of water flow and thus improving the filtration efficiency.

[0030] There are two end-sealing panels 9, which are located on the left and right sides of the PVC film shell 1 respectively. There are two fixed limiting rods 8, which are fixedly connected to the two end-sealing panels 9 respectively. There are multiple guide tubes 10, which are fixedly connected to the two end-sealing panels 9 respectively.

[0031] The diameter of the multiple guide tubes 10 is smaller than the diameter of the organic tubular membrane core 6. At the same time, the ends of the multiple guide tubes 10 away from the two end sealing panels 9 are inserted into the multiple organic tubular membrane cores 6 and located inside the organic tubular membrane cores 6. The main function is that when the liquid to be filtered enters the interior of the PVC membrane shell 1 through the end sealing panels 9, the multiple guide tubes 10 play a guiding role, so that the liquid can smoothly enter the interior of the multiple organic tubular membrane cores 6, thereby facilitating the permeation effect.

[0032] Working principle and usage process of this utility model:

[0033] Firstly, since a guide tube 10 is fixedly installed on the side of the end-sealing panel 9 near the organic tubular membrane core 6, the diameter of the guide tube 10 is smaller than the diameter of the organic tubular membrane core 6, and the guide tube 10 is located inside the organic tubular membrane core 6, when the liquid to be filtered enters the interior of the PVC membrane shell 1 through the end-sealing panel 9, the multiple guide tubes 10 play a guiding role, allowing the liquid to smoothly enter the interior of the multiple organic tubular membrane cores 6, thus achieving the effect of facilitating permeation.

[0034] Secondly, since an installation hole 5 is provided inside the fixed support frame 4, and an organic tubular membrane core 6 is inserted into the installation hole 5, both the fixed support frame 4 and the organic tubular membrane core 6 are located inside the PVC membrane shell 1. When the device is running normally, the fixed support frame 4 provides limiting support for the organic tubular membrane core 6 through its internal structure, so that the organic tubular membrane core 6 will not be twisted or deformed after working for a long time, thus achieving the effect of ensuring the overall stability of the device.

[0035] Meanwhile, the fixed support frame 4 is inserted into the fixed limiting rod 8, and the fixed support frame 4 and the fixed limiting rod 8 are fixed with glue. After the fixed support frame 4 is installed, it will be limited to prevent the position of the fixed support frame 4 from being displaced due to the rapid flow of water inside, thus ensuring the stability of the fixed support frame 4.

[0036] Finally, a groove 2 is provided inside the PVC membrane shell 1, and a slider 3 is slidably connected inside the groove 2. The slider 3 is fixedly connected to the fixed support frame 4. After the device has been working for a long time, the inside of the organic tubular membrane core 6 may become clogged due to a large amount of impurities. At this time, after the end sealing panel 9 is removed, the fixed support frame 4 can be removed by the sliding action of the slider 3 and the groove 2, thereby driving the organic tubular membrane core 6 to be disassembled. After disassembly, it is convenient to clean and unclog the inside of the organic tubular membrane core 6, thus improving the cleaning efficiency.
