Description

Technical Field

[0001] This utility model relates to the field of DTRO membrane module technology, specifically a DTRO membrane column and membrane sheet installation and connection device. Background Technology

[0002] DTRO membrane modules, also known as disc tube reverse osmosis membrane modules, are a form of reverse osmosis technology specifically designed for treating high-concentration wastewater. Their core technology lies in the construction of the disc tube membrane column. The main components of a DTRO membrane module include disc RO membranes, flow guide plates, O-rings, a central tie rod, and pressure-resistant sleeves. Currently, DTRO membranes are typically assembled by arranging them in alternating layers during installation, which is not only inefficient but also complex, involves a large amount of engineering work, and is difficult to maintain.

[0003] The prior art, patent application number 202421634329.9, describes a DTRO membrane column and membrane sheet installation and connection device, which includes a membrane housing. A membrane column is fixedly connected to the middle of the membrane housing, passing through the middle of the upper and lower end covers. This DTRO membrane column and membrane sheet installation and connection device places the membrane sheet in the middle of the guide plate, adds a sealing ring at the connection between the membrane sheet and the guide plate, inserts the membrane sheet into the middle of the slot opened in the membrane column through the insert, and then uses a hydraulic suction cup clamp to form a clamping and fixing structure for the membrane sheet, so as to ensure the stability and positional accuracy of the membrane sheet during the installation process. Furthermore, the hydraulic suction cup clamp can be adjusted according to different sizes and shapes of the membrane sheet to achieve adaptability to membrane sheet installation, improve membrane sheet installation efficiency, and enhance maintenance ease. However, when multiple DTRO membrane sheets are stacked together, it is difficult to individually install and remove DTRO membrane sheets in designated positions, thus making it inconvenient for their inspection and replacement. Utility Model Content

[0004] The purpose of this invention is to provide a DTRO membrane column and membrane sheet installation and connection device to solve the problem in the prior art where multiple DTRO membrane sheets are stacked together, making it difficult to individually install and remove DTRO membrane sheets at designated positions, thus making it inconvenient to inspect and replace them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a DTRO membrane column membrane installation and connection device, comprising a DTRO membrane, a flow guide plate, and a central tie rod. The DTRO membrane includes a first membrane and a second membrane, both of which are configured as semi-circular annular membranes. A protective frame is provided on the outer side of both the first and second membranes. The first and second membranes are inserted into a groove on one side of the flow guide plate. The middle part of the flow guide plate is sleeved on the outside of the central tie rod through an installation hole. The two ends of the central tie rod are fixed by screws, washers, and limiting nuts.

[0006] Furthermore, the groove is configured as an annular groove, and the depth of the groove is greater than the thickness of the first diaphragm.

[0007] Furthermore, the protective frame is made of rigid plastic, and the thickness of the protective frame is equal to the depth of the groove.

[0008] Furthermore, one end of the protective frame is provided with a plug-in post, and the other end of the protective frame is provided with a plug-in groove that engages with the plug-in post.

[0009] Furthermore, a limiting post is provided on the lower side of the protective frame, and a slot is provided at the bottom of the groove to engage with the limiting post.

[0010] Furthermore, the outer side of the central tie rod is provided with a limiting protrusion, and the inner wall of the mounting hole is provided with a limiting groove that slides with the limiting protrusion.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention sets the DTRO membrane into two semi-circular first and second membranes, which are inserted into the groove on one side of the flow guide plate. When assembling or disassembling the DTRO membrane, only the limiting nut at one end needs to be loosened to remove the membrane from the flow guide plate. The assembly and disassembly are convenient and quick. At the same time, it can also be used to assemble or disassemble the DTRO membrane in a specific position, which is convenient for maintenance and replacement.

[0012] This invention features protective frames on the outer sides of both the first and second membranes, increasing the structural strength of the outer surfaces of the membranes and facilitating better filtration. Additionally, one end of the protective frame has a plug-in post, and the other end has a plug-in groove for engaging with the post. This allows for improved stability in the lateral alignment and positioning of the first and second membranes by inserting the plug-in post into the corresponding groove.

[0013] This utility model features a limiting post on the lower side of the protective frame and a slot at the bottom of the groove that engages with the limiting post. This allows the stability of the first and second diaphragms when installed in the guide plate to be improved by inserting the limiting post on the lower side of the protective frame into the slot at the bottom of the groove.
