Description

Technical Field

[0001] This utility model belongs to the field of water-salt separation equipment operation protection, and in particular relates to a reverse osmosis membrane frame with a matching gate-type protective grid. Background Technology

[0002] Reverse osmosis membranes are water-salt separation devices that separate solutes and solvents in brine solutions. By applying external pressure to the high-concentration side of the natural osmosis process, the osmosis process is reversed, thus achieving water-salt separation and obtaining low-concentration low-salt solutions and high-concentration high-salt solutions.

[0003] The reverse osmosis membrane is housed in a matching container in the form of a standard specification element. During the operation of the reverse osmosis membrane equipment, the brine solution continuously enters the container at high speed, impacting the container and the reverse osmosis membrane element. This increases the risk of relative displacement between the containers, leading to malfunction of the reverse osmosis equipment.

[0004] During the operation of reverse osmosis membrane equipment, external pressure needs to be continuously applied to one side of the membrane to ensure the water-salt separation function and maintain the continuous and stable operation of the equipment. If the reverse osmosis membrane equipment fails, the components used to encapsulate the reverse osmosis membrane and its supporting container will be ejected from both ends of the equipment frame under pressure, causing damage and safety threats to the on-site equipment and operating personnel. Utility Model Content

[0005] The purpose of this utility model is to provide a reverse osmosis membrane frame with a matching gate-type protective grille. The frame provides support and fixation for the containers of the reverse osmosis membrane elements. While maintaining relative stability between the containers, gate-type protective grilles are installed at the front and rear ends of the frame in the longitudinal direction. This can not only ensure the safety of on-site personnel and equipment, but also allow the reverse osmosis membrane elements to be removed and replaced during equipment maintenance without affecting the main functions of the reverse osmosis equipment, thereby solving the technical problems existing in the background art.

[0006] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows:

[0007] A reverse osmosis membrane frame with a matching portal-type protective grid includes a membrane frame and portal-type protective grids disposed at both longitudinal ends of the membrane frame; the membrane frame is a cuboid frame welded from square tubes, and the portal-type protective grids are fitted onto the two longitudinal end faces of the membrane frame.

[0008] Furthermore, the membrane frame is a rectangular frame welded together from multiple sets of horizontally arranged base square tubes, vertically arranged column square tubes, and longitudinally arranged cross brace square tubes. The angles between the base square tubes, column square tubes, and cross brace square tubes are all right angles.

[0009] Furthermore, the membrane frame includes three sets of cross braces, with a spacing of 2.38m between the three sets of cross braces.

[0010] Furthermore, the gate-type protective fence includes two protective fences, each of which is made of steel square tubes welded into a frame, with a fence plate welded and fixed inside the frame; each piece is connected and fixed to the upright square tube by a hinge, and the opening and closing function of the gate-type protective fence is realized with the hinge as the rotation center.

[0011] Furthermore, the two protective fences are interlocked by inserting cylindrical steel pins into each other, and are also interlocked by inserting cylindrical steel pins into the square tubes of the base.

[0012] Furthermore, the grid is composed of crisscrossing thin steel strips forming a grid-like protective plate.

[0013] Furthermore, the grid is composed of perforated grids formed by stamping thin steel plates to form a perforated protective plate.

[0014] Furthermore, the diameter of the thin steel strips in the grid-shaped protective plate is 3mm or less, and the grid spacing is 30mm.

[0015] Furthermore, the porous protective plate is a porous grid plate formed by stamping thin steel plate, with a grid width or diameter of 10mm or less.

[0016] Furthermore, all square tubes are made of steel.

[0017] The reverse osmosis membrane frame with matching gate-type protective grilles of this utility model has the following advantages: the steel frame, which is welded from square tubes, provides support and fixation for the container and accessories that are matched with the reverse osmosis membrane. At the same time, gate-type protective grilles that can be opened and closed are installed at both ends of the longitudinal direction of the frame to prevent parts or components on the equipment from being ejected forward and backward under pressure when the reverse osmosis membrane fails, thus preventing damage to the equipment and operating personnel and improving the stability and safety of the reverse osmosis membrane equipment.

[0019] The markings in the diagram are as follows: 1. Membrane frame; 2. Portal protective fence; 3. Horizontal brace beam; 4. Hinge; 5. Base square tube; 6. Column square tube. Detailed Implementation

[0020] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a reverse osmosis membrane frame with a matching gate-type protective grid.

[0021] like Figure 1As shown, a reverse osmosis membrane frame with a matching portal-type protective grid according to the present invention includes a membrane frame 1 and portal-type protective grids 2 disposed at both longitudinal ends of the membrane frame 1; the membrane frame 1 is a cuboid frame welded from steel square tubes, and the portal-type protective grids 2 are fitted on the two longitudinal end faces of the membrane frame 1.

[0022] The membrane frame 1 is a rectangular frame made up of multiple sets of horizontally arranged base square tubes 5, vertically arranged column square tubes 6, and longitudinally arranged cross bracing square tubes 3. The angles between the base square tubes 5, column square tubes 6, and cross bracing square tubes 3 are all right angles.

[0023] The increased cross-sectional area of ​​the base square tube 5 ensures the stability of the reverse osmosis membrane equipment. The membrane frame 1 includes three sets of horizontal support beams 3, with a spacing of 2.38m between them. These beams are positioned laterally on the frame and are perpendicular to the container that houses the reverse osmosis membrane element, providing support and fixing points at the optimal stress points of the elongated container.

[0024] Two butterfly hinges 4 are provided on each of the front and rear vertical columns 6 of the membrane frame 1. The hinges are fixed to the vertical columns 6 by welding or bolting. The gate-type protective fence (2) is fixed to the other side of the hinge by welding or bolting.

[0025] The gate-type protective fence 2 includes two protective fences. Each protective fence is made of steel square tubes welded into a frame, and the inside is a fence plate welded and fixed inside the frame. Each piece is connected and fixed to the upright square tube 6 by a hinge 4, and the opening and closing function of the gate-type protective fence 2 is realized with the hinge 4 as the rotation center.

[0026] The gate-type protective barrier 2 is in a closed state by default. The two protective barriers are locked together by inserting cylindrical steel pins, and are also locked together by inserting cylindrical steel pins into the square tube 5 of the base. The gate-type protective barrier 2 is in a closed state when the reverse osmosis membrane is running. It can be manually opened during reverse osmosis membrane maintenance to remove or replace the reverse osmosis membrane element in the container.

[0027] The grating is composed of crisscrossing thin steel strips forming a grating-like protective plate, or a perforated protective plate made of thin steel sheet stamped into a perforated grating. It is welded and fixed to the frame in a fully-covered manner. The frame and grating are coated with a bright yellow anti-rust paint. The diameter of the thin steel strips in the grating-like protective plate is 3mm or less, and the strips are spaced 30mm apart. The perforated protective plate is a perforated grating made of thin steel sheet stamped into a perforated grating; the stamped grating can be square or round, and the grating width or diameter is 10mm or less.

[0028] A reverse osmosis membrane frame with a matching gate-type protective fence provides support and fixation for the reverse osmosis membrane equipment, reducing the risk of failure. The gate-type protective fence 2 can not only block the reverse osmosis membrane when it fails or when the components are pushed outward from both ends of the frame under pressure, but also prevent the operation and maintenance personnel or equipment operators from misoperating the reverse osmosis membrane while it is in operation, thus serving as a physical barrier.

[0029] The gaps in the gate-type protective grid 2 allow air to flow freely, without affecting the ventilation and heat dissipation of the reverse osmosis membrane equipment. At the same time, the protective grid, with its special grid structure, can isolate or disrupt the sound wave transmission of noise generated by the reverse osmosis membrane under pressure, thus reducing noise.
