Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 5 As shown, see Figures 1 to 5 As shown, the embodiment of the present invention provides an installation structure 10 for a tubular membrane for reclaimed water reuse, wherein the outer wall of the tubular membrane 20 is provided with a positioning groove 21, and the installation structure 10 comprises: a pipe interface 100, a connector 200 and a sealing member 300; the pipe interface 100 comprises a pipe portion 110 and a first positioning portion 120, wherein the side wall of the pipe portion 110 is provided with an opening at one end, and the first positioning portion 120 is provided on the inner side of the pipe portion 110 and is used for plugging and matching with the positioning groove 21; the connector 200 is detachably connected to the pipe interface 100 and is used for accommodating In the opening; the connecting member 200 includes a connecting portion 210 and a second positioning portion 220, the connecting portion 210 is used to enclose with the pipeline portion 110 to form an annular structure, the tubular membrane 20 is accommodated in the annular structure, and the second positioning portion 220 is used to be plugged and matched with the positioning groove 21 from the side of the tubular membrane 20 away from the first positioning portion 120; the sealing member 300 is movably connected to the pipeline interface 100, and the sealing member 300 is detachably connected to the pipeline portion 110 and the connecting portion 210, and the sealing member 300 is used to fix the connecting member 200 and the pipeline interface 100.

[0038] By using the mounting structure 10 of the present embodiment, by respectively setting the first positioning portion 120 on the pipe interface 100 and setting the second positioning portion 220 on the connecting piece 200, the first positioning portion 120 and the second positioning portion 220 respectively cooperate with the positioning groove 21 of the tubular membrane 20 to fix and seal the tubular membrane 20 and the mounting structure 10, and then the pipe interface 100 and the connecting piece 200 can be fixed by the movably arranged sealing member 300. The mounting structure 10 is easy to assemble and disassemble, and is convenient for assembling and disassembling the tubular membrane 20.

[0039] In the installation structure 10 of this embodiment, the first positioning portion 120 and the second positioning portion 220 are provided in cooperation with the tubular membrane 20 to achieve the functions of sealing and convenient installation and positioning. The sealing member 300 is provided in cooperation with the pipeline interface 100 and the connection to achieve the function of convenient disassembly and assembly. The structure is simple and the use effect is good.

[0040] Furthermore, the first positioning portion 120 is provided with a first guide surface 121, and an angle is formed between the first guide surface 121 and the axis of the pipeline portion 110; on the moving path when the tubular membrane 20 is installed in the pipeline portion 110, the first guide surface 121 is in sliding contact with the inner wall of the positioning groove 21 and is used to drive the inner wall of the positioning groove 21 to press against one side surface of the first positioning portion 120.

[0041] In this embodiment, by providing a first guide surface 121 on the first positioning portion 120 of the pipeline interface 100, when the tubular membrane 20 is connected to the pipeline interface 100, the inner wall of the positioning groove 21 can contact the first positioning portion 120 and slide with the first guide surface 121. Since there is an angle between the first guide surface 121 and the axis of the pipeline portion 110, as the tubular membrane 20 moves in the pipeline interface 100 and is installed in place, the first guide surface 121 can drive the tubular membrane 20 to move in the axial and radial directions of the pipeline portion 110 at the same time and guide it to a preset position until the tubular membrane 20 is pressed against the first positioning portion 120, thereby ensuring the sealing between the tubular membrane 20 and the pipeline interface 100. Compared with the traditional installation method of tubular membranes: splicing the two halves of the buckling structure on the outside of the tubular membrane and fixing them by a hoop, the sealing between the tubular membrane 20 and the installation structure 10 can be effectively improved, and the installation convenience is improved.

[0042] Furthermore, the second positioning portion 220 is provided with a second guide surface 221, and an angle is formed between the second guide surface 221 and the axis of the connecting portion 210, and the opening direction of the angle between the second guide surface 221 and the first guide surface 121 is opposite; on the moving path of the connecting member 200 and the tubular membrane 20, the second guide surface 221 is in sliding contact with the inner wall of the positioning groove 21 and is used to drive the inner wall of the positioning groove 21 to press against one side surface of the second positioning portion 220, and one side surface of the second positioning portion 220 and one side surface of the limiting groove 122 are located in the same plane.

[0043] According to the arrangement, when the connector 200 is connected to the tubular membrane 20 in the pipeline interface 100, the second guide surface 221 can contact and slide relatively with the side of the positioning groove 21 away from the first positioning portion 120. During the installation process of the connector 200, the connector 200 will first be guided by the axial and radial movement relative to the pipeline interface 100 through the cooperation of the second guide surface 221 and the positioning groove 21. After the connector 200 is combined with the pipeline interface 100, the connector 200 can cooperate with the pipeline interface 100 and react to the tubular membrane 20 to seal the connector 200 with the tubular membrane 20. The mounting structure 10 and the tubular membrane 20 are sealed and fixed, thereby ensuring the overall sealing between the mounting structure 10 and the tubular membrane 20, and the cooperation between the second guide surface 221 and the positioning groove 21 can improve the installation convenience and installation accuracy between the tubular membrane 20 and the connecting piece 200, and then the sealing piece 300 is fixed to the pipeline interface 100 and the connecting piece 200 to complete the combined installation and fixation of the mounting structure 10 and the tubular membrane 20; when the tubular membrane 20 needs to be removed, the tubular membrane 20 can be removed by simply separating the sealing piece 300 from the connecting piece 200, which has a simple structure, convenient disassembly and assembly, and good sealing performance.

[0044] In one embodiment, the second positioning portion 220 is further provided with an inserting groove 222 , the projection of the inserting groove 222 is crescent-shaped, the first positioning portion 120 is plugged into the inserting groove 222 , and the first positioning portion 120 and the second positioning portion 220 are positioned and matched through the inserting groove 222 .

[0045] In this embodiment, when the connecting piece 200 is connected to the pipe interface 100, by providing a plug-in groove 222 on the second positioning portion 220 to cooperate with the first positioning portion 120, the connecting piece 200 and the pipe interface 100 can be installed and positioned, and the combination tightness between the two can be improved. After the first positioning portion 120 is accommodated in the plug-in groove 222, the first positioning portion 120 and the second positioning portion 220 can be positioned again, thereby further improving the sealing performance of the connecting piece 200 and the pipe interface 100.

[0046] Furthermore, the first positioning portion 120 is also provided with a limiting groove 122 , the opening of the limiting groove 122 is L-shaped, and the limiting groove 122 is snap-fitted with the connecting portion 210 and is used to limit and position the connection between the pipe interface 100 and the connecting piece 200 .

[0047] With this arrangement, when the connector 200 is connected to the pipe interface 100, the limiting groove 122 can abut against the connecting portion 210, and the installation of the connector 200 is limited by the contact between the inner wall of the limiting groove 122 and the connecting portion 210, thereby further improving the convenience of assembly and disassembly, and the structure is simple and easy to manufacture.

[0048] In one embodiment, the connecting portion 210 is provided with a limiting surface 212, which is provided on the inner side of the connecting portion 210 and is located on one side of the first positioning portion 120. When the connecting member 200 is connected to the pipeline interface 100, the limiting surface 212 abuts against the side of the first positioning portion 120 away from the first guide surface 121.

[0049] In this embodiment, by setting an upper limit surface 212 on the connecting portion 210, when the first positioning portion 120 is connected to the connecting member 200, the limiting surface 212 can abut against a side surface of the first positioning portion 120 away from the first guide surface 121, thereby limiting the connecting member 200 on one axial side of the pipe interface 100 to prevent the connecting member 200 from escaping from the preset installation position in the pipe interface 100, thereby further improving the installation convenience and installation accuracy between the connecting member 200 and the pipe interface 100.

[0050] In one embodiment, the outer wall of the pipe portion 110 is provided with a first threaded portion 111, and the outer wall of the connecting portion 210 is provided with a second threaded portion 211. When the connecting member 200 is connected to the pipe interface 100, the first threaded portion 111 and the second threaded portion 211 are combined to form a complete threaded structure, the sealing member 300 is rotatably connected to the pipe interface 100, and the sealing member 300 is used for threaded connection with the threaded structure.

[0051] According to the arrangement, when it is necessary to install the tubular membrane 20 in the pipeline interface 100, the sealing member 300 can be firstly rotated in the opposite direction to separate the sealing member 300 from the first threaded portion 111 and the second threaded portion 211 so as to release the connecting member 200, and then the connecting member 200 is separated from the pipeline interface 100 and the tubular membrane 20 is installed inside the pipeline interface 100, and the positioning groove 21 is matched with the first positioning portion 120 for positioning; then the connecting member 200 is positioned and connected to the tubular membrane 20 through the second positioning portion 220 and the positioning groove 21, and when the connecting member 200 is connected to the tubular membrane 20, the connecting member 200 is connected to the tubular membrane 20. After the connector 200 is installed in place in the pipe interface 100, the complete threaded structure formed by the seal 300, the first threaded portion 111 and the second threaded portion 211 can be threadedly matched by rotating the seal 300. The limit surface 212 and the pipe interface 100 can cooperate to position the axial installation of the connector 200, and the seal 300 can position the radial direction of the connector 200. In this way, the connector 200 and the pipe interface 100 can be precisely installed and positioned, thereby ensuring the sealing between the installation structure 10 and the tubular membrane 20.

[0052] Furthermore, the outer peripheral wall of the sealing member 300 is provided with anti-slip patterns 310 .

[0053] It can be understood that by providing anti-slip grooves 310 on the outer peripheral wall of the seal 300, when the operator needs to rotate the seal 300, the friction on the surface of the seal 300 can be increased, thereby facilitating the operation of the seal 300; of course, in some embodiments, the anti-slip grooves 310 can also be replaced with positioning grooves or positioning surfaces, so that the operator can disassemble and assemble the seal 300 using tools such as wrenches.

[0054] In one embodiment, the pipe interface 100 is further provided with a limiting flange 130 , which is arranged around the outer peripheral wall of the pipe portion 110 . When the seal 300 is separated from the threaded structure, the limiting flange 130 abuts against the side of the seal 300 away from the connector 200 .

[0055] With this arrangement, after the seal 300 is separated from the first threaded portion 111 and the second threaded portion 211 respectively, the movement of the seal 300 can be limited by the limiting flange 130 to prevent the seal 300 from falling off the pipe portion 110, and the structure is simple.

[0056] The present invention also provides a filtering device, which includes a tubular membrane 20 and an installation structure 10 in any one of the above-mentioned embodiments; a positioning groove 21 is provided on the outer peripheral wall of the tubular membrane 20; the pipe interface 100 of the installation structure 10 is used to connect the tubular membrane 20, the connecting piece 200 is used to enclose and seal the installation structure 10 and the tubular membrane 20 with the pipe interface 100, and the sealing piece 300 is used to fix the connecting piece 200 and the pipe interface 100.

[0057] It can be understood that in the filtration device of this embodiment, by setting the installation structure 10 in any one of the above embodiments to cooperate with the tubular membrane 20, the installation structure 10 of this embodiment can achieve the functions of sealing and convenient installation and positioning by setting the first positioning part 120 and the second positioning part 220 to cooperate with the tubular membrane 20, and by setting the sealing member 300 to cooperate with the pipeline interface 100 and the connection, the function of convenient disassembly and assembly can be achieved, the structure is simple, and the use effect is good.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
