Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a water collecting pipe component of a curtain-type membrane. Background Art

[0002] The curtain-type MBR membrane is a suspended structure, generally including multiple membranes and water collection pipes. The membrane includes membrane tubes and membrane fibers. When in use, the curtain-type MBR membrane assembly is placed in the sewage pool. Under the action of negative pressure, water enters the membrane fibers from the outside, while impurities are left outside the membrane fibers, and the filtered water flows into the water collection pipe through the membrane tubes.

[0003] At present, most curtain-type MBR membrane devices use hoses to connect the membrane tubes and the water collection pipes. Each time the hoses are installed, they need to be installed one by one, and both ends of each hose need to be installed, which makes the installation process very cumbersome. At the same time, the more connection points, the more leakage points there are, and leakage problems may occur at any time. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a water collecting pipe assembly for a curtain membrane, which can simplify the installation steps and reduce the possibility of water leakage.

[0005] To this end, the technical solution of the utility model is: a curtain membrane water collecting pipe assembly, including a water collecting pipe main body, on which a plurality of connecting pipes are provided, and the connecting pipes are connected to the interior of the water collecting pipe main body; the connecting pipes include a first straight section, a corrugated section and a second straight section, the first straight section and the water collecting pipe main body are fixed together by hot melt, and the port of the second straight section is a connection interface.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the two ends of the corrugated section are respectively fixed to the first straight section and the second straight section by hot melting, and the three are fixed as a whole.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the corrugated section is an S-shaped corrugated tube structure, and a spiral metal wire is embedded in the tube wall of the corrugated section.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the water collecting pipe body is a square tubular structure, and a total water outlet is provided at the end of the water collecting pipe body.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the connection interface is an internal thread interface, an external thread interface or a quick-connect interface.

[0010] Compared with the prior art, the beneficial effects of the utility model are: a flexible connecting pipe is hot-melt fixed on the water collecting pipe, and a corrugated section is provided on the connecting pipe, which can be bent at any angle and is connected to the membrane tube of the diaphragm. During installation, only the connecting pipe and the membrane tube need to be installed, which greatly simplifies the installation steps and speeds up the installation efficiency. Moreover, after the connection points of the pipeline are reduced, the risk of water leakage is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In the description of the present invention, it should be noted that directional words, such as the terms "center", "lateral (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present invention.

[0016] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.

[0017] See the attached drawings. The water collecting pipe assembly of the curtain membrane described in this embodiment includes a water collecting pipe body 1. The water collecting pipe body 1 is a square tubular structure, and a total water outlet 11 is provided at the end of the water collecting pipe body 1. A plurality of connecting pipes 2 are fixed on the water collecting pipe body 1, and the connecting pipes 2 are connected to the inside of the water collecting pipe body 1; the connecting pipes 2 include a first straight section 21, a corrugated section 22, and a second straight section 23. The first straight section 21 is fixed to the water collecting pipe body 1 as a whole by hot melting, and the port of the second straight section 23 is a connecting interface, and the connecting interface is an internal thread interface, an external thread interface or a quick-connect interface, or other existing interface structures. The two ends of the corrugated section 22 are fixed to the first straight section 21 and the second straight section 23 by hot melting, and the three are fixed as a whole.

[0018] The corrugated section 22 is an S-shaped corrugated tube structure. The S-shaped corrugation is easier to bend and expand. At the same time, a spiral metal wire is embedded in the tube wall of the corrugated section, which not only enhances the toughness of the corrugated tube, but also does not affect the bending of the corrugated section.

[0019] The water collecting pipe body 1 and the first straight section 21 and the second straight section 23 of the connecting pipe 2 are made of the same material, such as PVC, PE, UPVC, ABS, etc., wherein the material of the corrugated section 22 of the connecting pipe 2 can be selected from a more fold-resistant material, such as polyethylene, polypropylene, etc., and a spiral metal wire is added in the middle to increase the strength. The section can be processed in sections and then hot-melted together to form an integral component, which not only reduces the installation difficulty by half, but also reduces the interfaces by half, thereby reducing the risk of water leakage.

[0020] During installation, the water collecting pipe body is fixedly installed on the curtain-type MBR membrane device, and then the membrane tubes of the membrane elements are connected to each connecting pipe one by one, so that the membrane tubes are connected to the inside of the water collecting pipe body, and the filtered influent water is sent into the water collecting pipe body.

[0021] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
