Description

Technical Field

[0001] This utility model relates to the field of brine filter technology, and more specifically, to a magnetic frame and a brine filter. Background Technology

[0002] The brine in the ion-exchange membrane caustic soda production process consists of dilute brine returned from the electrolysis unit and chemically treated refined brine. In the primary brine refining stage, the ion-exchange membrane process typically employs a dual-alkali method, removing harmful cationic impurities through precipitation and filtration. The secondary brine refining equipment includes an ion exchange resin tower with chelating resin, primarily removing calcium and magnesium ions to obtain qualified refined brine suitable for electrolysis. Because the brine contains a high content of magnetic substances such as iron after the primary refining stage, the resin tower cannot adsorb these substances during the secondary refining process, affecting the quality of the brine and the caustic soda product. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic rack and a brine filter. By installing a magnetic rack inside the brine filter during the primary brine refining process, magnetic substances such as iron in the primary brine can be adsorbed in real time, effectively reducing the content of magnetic substances in the primary brine, thereby improving the quality of the subsequently produced brine and caustic soda products.

[0004] The technical solution adopted in this utility model is as follows:

[0005] In a first aspect, this application provides a magnetic rack, comprising:

[0006] The magnetic adsorption rods are arranged in multiple layers, with each layer consisting of multiple magnetic adsorption rods that are parallel to each other and spaced apart.

[0007] The mounting brackets consist of two spaced-apart brackets, with a magnetic adsorption rod positioned between them. The axis of the magnetic adsorption rod is perpendicular to the plane of the mounting brackets. Each mounting bracket has a liquid inlet and outlet.

[0008] Fixing components are provided at both ends of each magnetic adsorption rod to fix the magnetic adsorption rod to the mounting frame.

[0009] Furthermore, in some embodiments of this utility model, the magnetic adsorption rod includes a protective shell and a magnetic rod disposed inside the protective shell, and the fixing member is connected to the protective shell.

[0010] Furthermore, in some embodiments of this utility model, the mounting bracket includes a plurality of parallel and spaced-apart transverse mounting plates and a plurality of parallel and spaced-apart longitudinal mounting plates, the transverse mounting plates and the longitudinal mounting plates abutting against each other, and the transverse mounting plates and the longitudinal mounting plates surrounding each other to form a liquid inlet and outlet.

[0011] Furthermore, in some embodiments of this utility model, the fixing member includes a bolt, which passes through the mounting bracket and is threadedly connected to the end of the magnetic adsorption rod.

[0012] Secondly, this application provides a salt water filter, including the aforementioned magnetic frame, and also includes a filter housing, in which a filter membrane is provided, the filter membrane dividing the interior of the filter housing into a pre-filtration chamber and a post-filtration chamber, the pre-filtration chamber being located below the post-filtration chamber;

[0013] The filter housing has a liquid inlet communicating with the pre-filtration chamber and a liquid outlet communicating with the post-filtration chamber, with the magnetic frame located in the post-filtration chamber.

[0014] Furthermore, in some embodiments of this utility model, the magnetic frame is located at the liquid outlet, and the axis of the magnetic adsorption rod is perpendicular to the plane where the liquid outlet is located.

[0015] Compared with the prior art, the present invention has at least the following advantages or beneficial effects:

[0016] In this application, the brine enters the filter housing through the liquid inlet and is located in the pre-filtration chamber. The filter membrane filters the material, and the filtered clear liquid is located in the post-filtration chamber, where it passes through a magnetic rack. The clear liquid flows from the liquid inlet / outlet at one end of the magnetic rack into the magnetic adsorption rod area. At this time, magnetic substances such as iron in the clear liquid can be adsorbed by the magnetic adsorption rod. After adsorption treatment, the clear liquid flows through the liquid inlet / outlet at the other end of the magnetic rack into the liquid outlet, then into the overflow tank, and finally into the primary brine tank. By installing a magnetic rack in the brine filter during the primary brine refining process, magnetic substances such as iron in the primary brine can be adsorbed in real time, effectively reducing the content of magnetic substances in the primary brine, thereby improving the quality of the subsequently produced brine and caustic soda products, and preventing the introduction of other impurities that could cause secondary contamination of the primary brine.

[0026] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0027] Example

[0028] Please refer to Figures 1-3 This embodiment provides a magnetic rack 10, including a magnetic adsorption rod 11, a mounting bracket 12, and a fixing member 13.

[0029] The magnetic adsorption rods 11 are arranged in multiple layers, each layer including multiple parallel and spaced-apart magnetic adsorption rods 11; for example... Figure 2 As shown, this embodiment preferably uses nine magnetic adsorption rods 11 arranged in a three-horizontal-three-vertical matrix. Each magnetic adsorption rod 11 includes a protective shell 112 and magnetic rods 113 disposed inside the protective shell 112. In this embodiment, the protective shell 112 is made of titanium, which has anti-corrosion properties, preventing corrosion and damage to the internal magnetic rods 113 and improving their service life. The magnetic rods 113 are commonly used cylindrical magnets, and preferably, multiple magnetic rods 113 are interconnected and installed inside the protective shell 112. Specifically, the protective shell 112 can be composed of two cylindrical parts, which can be connected by threads (one end of the cylindrical part has an external thread, and the other end of the cylindrical part has an internal thread) to form a sealed structure, thus facilitating the installation of the magnetic rods 113 inside the protective shell 112.

[0030] Two mounting brackets 12 are arranged at intervals. A magnetic adsorption rod 11 is positioned between the two mounting brackets 12, with its axis perpendicular to the plane of the mounting bracket 12. Each mounting bracket 12 has a liquid inlet / outlet 121. The mounting bracket 12 includes multiple parallel and spaced-apart transverse mounting plates 122 and multiple parallel and spaced-apart longitudinal mounting plates 123. The transverse mounting plates 122 and longitudinal mounting plates 123 abut against each other, forming the liquid inlet / outlet 121. Figure 2 As shown, this embodiment preferably uses three horizontal mounting plates 122 and three vertical mounting plates 123.

[0031] Each magnetic adsorption rod 11 has a corresponding fixing member 13 at both ends, which fixes the magnetic adsorption rod 11 to the mounting frame 12. In this embodiment, the fixing member 13 includes a bolt, which passes through the mounting frame 12 and is threadedly connected to the end of the magnetic adsorption rod 11. This fixing member 13 facilitates installation and removal, thereby facilitating the installation of each magnetic adsorption rod 11 and flexibly adjusting the number of magnetic adsorption rods 11 installed.

[0032] This embodiment also provides a brine filter, including the aforementioned magnetic frame and a filter housing 20. A filter membrane 21 is disposed within the filter housing 20, dividing the interior of the filter housing 20 into a pre-filtration chamber 22 and a post-filtration chamber 23. The pre-filtration chamber 22 is located below the post-filtration chamber 23. In this embodiment, the filter membrane 21 is a primary brine organic filter membrane. The filter housing 20 has a liquid inlet 24 communicating with the pre-filtration chamber 22 and a liquid outlet 25 communicating with the post-filtration chamber 23. The magnetic frame is located within the post-filtration chamber 23 and can be fixed to the filter housing 20. The magnetic frame is located at the liquid outlet 25, and the axis of the magnetic adsorption rod 11 is perpendicular to the plane of the liquid outlet 25. The longitudinal cross-section of the magnetic frame is larger than that of the liquid outlet 25. The magnetic frame can completely block the liquid outlet 25. In this way, the flowing salt water flows from one end of the magnetic adsorption rod 11 to the other end, and the distance it travels through the magnetic adsorption rod 11 is longer, which is beneficial to improving the adsorption efficiency of the magnetic adsorption rod 11 for magnetic materials.

[0033] The working principle is as follows:

[0034] In the specific implementation process, such as Figure 4As shown, after saturated brine is prepared in salt bath 31, it is siphoned into coarse filter 32 to coarsely filter the material and obtain coarse brine. The coarse brine is pumped to the front reaction tank 33 and caustic soda and soda ash are added. After the brine reacts completely in the front reaction tank 33, it is pumped to pressurized dissolved gas tank 34 and then flows into pre-processor 35 by gravity. In pre-processor 35, sludge settles, suspension floats, and clear liquid flows out from the side into the rear reaction tank 36. Then the brine enters buffer tank 37. After a certain level of material is added to buffer tank 37, it flows by gravity through liquid inlet 24 into filter box 20 and is located in the pre-filtration chamber 22. Filter membrane 21 filters the material, and the filtered clear liquid is located in the post-filtration chamber 23. At this time, the clear liquid passes through magnetic rack 10. The clear liquid flows into the area where the magnetic adsorption rod 11 is located from the liquid inlet 121 at one end of the magnetic rack 10. At this time, the magnetic substances such as iron in the clear liquid can be adsorbed by the magnetic adsorption rod 11. After adsorption treatment, the clear liquid flows into the liquid outlet 25 through the liquid inlet 121 at the other end of the magnetic rack 10, and then enters the overflow tank 38 through the liquid outlet 25, and finally enters the primary brine tank 39.

[0035] Thus, by installing a magnetic rack 10 in the brine filter during the primary brine refining process, this application can adsorb magnetic substances such as iron in the primary brine in real time, effectively reducing the content of magnetic substances in the primary brine, thereby improving the quality of the brine and caustic soda products produced subsequently, and avoiding the introduction of other impurities that would cause secondary contamination of the primary brine.

[0036] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two. In this application embodiment, the limitations on relative positional relationships such as parallel, perpendicular, and aligned are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallel, perpendicular, and aligned are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.
