Description

Technical Field

[0001] This invention relates to the field of filter membrane technology, and in particular to a filter manifold. Background Technology

[0002] In traditional ultrafiltration hollow membrane modules, each hollow membrane is connected to a delivery pipeline via a delivery connector. The delivery pipeline is mounted on a support frame. Figure 3 As shown, several hollow membranes c1 require several separate conveying connectors c2 for connection, and each conveying connector c2 is then connected to a corresponding input pipeline ( Figure 3 (The connection is omitted in the text.) The input pipelines are interspersed, occupying a large space and making the entire conveying system quite complex.

[0003] Furthermore, a filter manifold has emerged on the market, comprising membrane tube connectors that connect to each hollow membrane, with each connector corresponding to one of the hollow membranes. For example, the raw liquid delivery pipe in a water treatment device with patent publication number CN203737115U.

[0004] During processing, each membrane tube connector (i.e., the raw material delivery pipe) is prefabricated by welding in the factory. However, due to differences in melting temperature, deviations may occur when the membrane tube connectors are welded together along the same central axis. In addition, the circumferential joint position of the membrane tube connectors is not easy to control during welding, and the membrane tube connectors are prone to circumferential misalignment.

[0005] In view of this, the inventor of this case conducted in-depth research, which led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide a filter manifold that is quick, easy, and precise to assemble.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A filter manifold includes a plurality of membrane tube connectors that are sequentially inserted and assembled together. Each membrane tube connector is a T-shaped tee connector and includes a membrane tube connection end, a first insertion end, and a second insertion end. The first insertion end and the second insertion end are arranged opposite to each other. Adjacent membrane tube connectors in the filter manifold are connected together by the first insertion end and the second insertion end, and the first insertion end and the second insertion end are bonded together by adhesive, with an adhesive layer formed between the first insertion end and the second insertion end.

[0009] The first plug end is provided with a positioning protrusion or a positioning groove, and the second plug end is provided with another positioning groove or positioning protrusion. The positioning protrusion of the first plug end matches the positioning groove of the second plug end, and the positioning groove of the first plug end matches the positioning protrusion of the second plug end.

[0010] Furthermore, the first plug-in end is a plug connector, the outer diameter of which is reduced to form a limiting step; the second plug-in end is a plug sleeve, the inner diameter of which is expanded to form another limiting step; the shape and size of the plug sleeve are respectively matched with the plug connector.

[0011] Furthermore, the outer diameter of the second insertion end is flush with the outer periphery of the limiting step of the first insertion end.

[0012] Furthermore, the positioning protrusion is a key bar, which is arranged along the axial direction of the filter manifold, and the positioning groove is a keyway, which is arranged along the axial direction of the filter manifold.

[0013] Furthermore, the first plug-in end and the second plug-in end are provided with at least two sets of the positioning protrusions and the positioning grooves.

[0014] Furthermore, the filter manifold also includes end connectors located at both ends of its axial direction. One end of the end connector is inserted into a corresponding membrane tube connector. The insertion structure between the end connector and the membrane tube structure is the same as the connection structure between the membrane tube connector and the membrane tube connector.

[0015] After adopting the above technical solution, the present invention provides a filter manifold with the following advantages: It features a three-way membrane tube connector, and then assembles the various membrane tube connectors to form the filter manifold. As can be seen, the present invention integrates the filtrate delivery pipeline and the filter membrane connector into one unit, simplifying the pipeline connection system and resulting in a simple structure. During assembly, it can be quickly plugged in on-site, offering good flexibility. Adhesive bonding ensures a stable plug-in structure. During assembly, adhesive is applied to the first and / or second plug-in ends before plugging them together. Compared to traditional filter manifolds that require prefabrication and welding in the factory, the present invention is flexible, convenient, simple in structure, and allows for quick plugging. Furthermore, the present invention includes a positioning mechanism (consisting of a positioning protrusion and a positioning groove), which allows for rapid positioning during plugging, quickly locking the relative positions of the plug ends and preventing displacement of the plug ends along the circumferential direction of the filter manifold during plugging, thus avoiding impact on the subsequent installation of the hollow fiber membrane. Typically, the inlet ends of several hollow fiber membranes are connected to the same main filter pipe, while the outlet ends of several hollow fiber membranes are connected to another main filter pipe. If the connectors shift circumferentially, causing dimensional deviations in the installation, the inlet or outlet of the same hollow fiber membrane may not align properly, or different hollow fiber membranes may not align completely. Therefore, a positioning mechanism can improve the accuracy and speed of the connection, enabling rapid alignment and precise connection. Attached Figure Description

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] like Figure 1 and Figure 2As shown, this utility model discloses a filter manifold a, comprising a plurality of membrane tube connectors 1 sequentially inserted and assembled together. Each membrane tube connector 1 is T-shaped and a tee connector, including a membrane tube connecting end 11, a first insertion end 12, and a second insertion end 13. The membrane tube connecting end 11 is used to connect to a hollow tube b (filter membrane). The first insertion end 12 and the second insertion end 13 are arranged opposite to each other. Adjacent membrane tube connectors 1 in the filter manifold a are connected together via the first insertion end 12 and the second insertion end 13, and are also bonded together by adhesive. An adhesive layer is formed between the first insertion end 12 and the second insertion end 13.

[0023] The first plug end 12 is provided with a positioning protrusion or a positioning groove, and the second plug end 13 is provided with another positioning groove or positioning protrusion. The positioning protrusion of the first plug end 12 matches the positioning groove of the second plug end 13, and the positioning groove of the first plug end 12 matches the positioning protrusion of the second plug end 13.

[0024] In this embodiment, the first insertion end 12 is provided with a positioning groove 31, and the second insertion end 13 is correspondingly provided with a positioning protrusion 32. The positioning groove 31 and the positioning protrusion 32 constitute a positioning mechanism, and each pair of cooperating first insertion ends 12 and second insertion ends 13 is provided with two sets of positioning mechanisms. The two sets of positioning mechanisms are correspondingly arranged, and the two sets of positioning mechanisms are located in the direction of the diameter of the filter main pipe a. In this utility model, the number of positioning mechanisms can be set according to actual needs, and the positions of the positioning groove 31 and the positioning protrusion 32 can also be set according to actual conditions. The setting of the positioning mechanism can improve the alignment accuracy of the membrane tube connectors 1 in the circumferential direction and reduce the relative positional deviation between them in the circumferential direction.

[0025] This invention relates to a filter manifold a, which includes a three-way membrane tube connector 1, and the various membrane tube connectors 1 are assembled to form the filter manifold 1. As can be seen, the filter manifold 1 of this invention integrates the filtrate delivery pipeline and the filter membrane connector into one unit, simplifying the pipeline connection system and resulting in a simple structure. During assembly, it can be quickly plugged in on-site, offering good flexibility, and is bonded with adhesive, resulting in a stable structure. During assembly, adhesive is first applied to the first plug-in end 12 and / or the second plug-in end 13 before plugging them together. Compared to traditional filter manifolds that require prefabrication and welding in the factory, this invention is flexible, convenient, simple in structure, and allows for quick plugging. Furthermore, this invention includes a positioning mechanism that allows for rapid positioning during plugging, quickly locking the relative positions of the plug ends to prevent displacement of the plug ends along the circumferential direction of the filter manifold a during plugging, which could affect the subsequent installation of the hollow membrane b. Typically, the inlet ends of several hollow fiber membranes (b) are connected to the same main filter pipe, and the outlet ends of several hollow fiber membranes (b) are connected to another main filter pipe. If the insertion ends shift circumferentially, causing dimensional deviations in the installation, the inlet or outlet of the same hollow fiber membrane (b) may not be aligned, or different hollow fiber membranes (b) may not be aligned. Therefore, a positioning mechanism can improve the accuracy and speed of insertion, enabling rapid alignment and precise connection.

[0026] In a preferred embodiment, the first insertion end 12 is a connector with a narrowed outer diameter forming a limiting step 121. The second insertion end 13 is a connector sleeve with an expanded inner diameter forming another limiting step 131. The shape and size of the connector sleeve match the connector. After insertion, the sleeve end is positioned along the limiting step 121, and the connector end is positioned along the limiting step 131.

[0027] Furthermore, the outer diameter of the second insertion end 13 is flush with the outer periphery of the limiting step 121.

[0028] In a preferred embodiment, the positioning protrusion 32 is a key bar, which is arranged along the axial direction of the filter main tube a, and the positioning groove 31 is a keyway, which passes through the end edge of the corresponding connection end. The keyway being arranged along the axial direction of the filter main tube a allows for rapid positioning when the first insertion end 12 and the second insertion end 13 are inserted, improving the accuracy of the insertion, especially the accuracy of the position relative to the circumferential direction of the filter main tube a, facilitating the precise positioning and connection of subsequent hollow tubes to each filter main tube a. It also improves the stability of the structure after insertion.

[0029] In a preferred embodiment, the first insertion end 12 and the second insertion end 13 are provided with two sets of positioning grooves 31 and positioning protrusions 32. This can further improve the insertion speed and enhance the stability of the insertion structure.

[0030] In one preferred embodiment, the filter manifold a further includes end connectors 2 disposed at both ends of its axial direction. One end of the end connector 2 is inserted into the corresponding membrane tube connector 1. The insertion structure between the end connector 2 and the membrane tube connector 1 is the same as the connection structure between the membrane tube connector 1, and will not be described in detail here.

[0031] The above embodiments and accompanying drawings are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
