Description

Technical Field

[0001] This utility model relates to the field of industrial processing equipment technology, specifically to a magnesium chloride purification and filtration device. Background Technology

[0002] In the purification process of magnesium chloride, flocculants are usually added to remove impurities, causing them to float or precipitate. These floating objects and precipitates need to be effectively separated by a filtration device to obtain a high-purity magnesium chloride solution.

[0003] Traditional magnesium chloride purification and filtration devices typically house their core filter components (such as filter screens and media) internally. This built-in design leads to clogging as floating matter and sediment accumulate on the filter components over time, reducing filtration efficiency. To maintain filtration effectiveness, regular cleaning or replacement of the filter components is necessary. Since these components are internal, cleaning or replacement requires stopping the entire filtration system – a periodic shutdown. This process is not only time-consuming and labor-intensive, but more importantly, it disrupts the continuity of the magnesium chloride purification process, forcing production to halt. Frequent shutdowns for cleaning reduce overall efficiency and increase production costs. Therefore, we propose a magnesium chloride purification and filtration device to address these issues.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This application provides a magnesium chloride purification and filtration device, mainly to solve the problem of existing traditional magnesium chloride purification and filtration devices, in which the core filter elements (such as filter screens and filter media) are generally located inside the device. This built-in structural design leads to the problem that, during the filtration process, floating matter and sediment gradually adhere to the filter elements over time, causing clogging and reducing filtration efficiency. The application provides the following technical solution, which will be discussed in conjunction with... Figure 1 - Figure 4 Please provide a detailed explanation:

[0025] A magnesium chloride purification and filtration device, comprising:

[0026] The first filter cylinder 1 has an open top structure. A feed pipe 2 is connected to the bottom of one side of the first filter cylinder 1, and an overflow pipe 3 is connected to the top of the other side of the first filter cylinder 1. A cross 4 is fixed inside the bottom of the first filter cylinder 1.

[0027] A stainless steel mesh cylinder 5 is placed above the cross 4. The stainless steel mesh cylinder 5 is slidably connected to the inner wall of the first filter cylinder 1. The inside of the stainless steel mesh cylinder 5 is filled with the first filter material 6, which is volcanic rock. The upper end of the stainless steel mesh cylinder 5 protrudes outward from the upper port of the first filter cylinder 1.

[0028] The second filter cartridge 7 has an open top structure. The second filter cartridges 7 are evenly spaced on the side of the first filter cartridge 1. The upper side wall of the second filter cartridge 7 closest to the first filter cartridge 1 is connected to the overflow pipe 3. The adjacent second filter cartridges 7 are connected by a guide pipe 8. The bottom side of the second filter cartridge 7 away from the first filter cartridge 1 is connected to a discharge pipe 9.

[0029] The second filter material 10 is filled inside the second filter cylinder 7. The second filter material 10 is an activated carbon rod, and its upper end protrudes outward from the upper port of the second filter cylinder 7.

[0030] Workflow Description

[0031] Raw material input: Magnesium chloride solution containing impurities enters the bottom of the first filter cartridge 1 through feed pipe 2;

[0032] Preliminary filtration: As the solution continuously enters the first filter cartridge 1, the water level in the first filter cartridge 1 rises and first comes into contact with the stainless steel mesh cylinder 5 placed above the cross 4. The stainless steel mesh cylinder 5 is filled with volcanic rock as the first filter material 6. When the solution passes through the gaps in the volcanic rock, larger particles of impurities are intercepted. At the same time, the porous structure of the volcanic rock can also adsorb some smaller particles of impurities, completing the preliminary filtration. During this process, some impurities will settle at the bottom of the first filter cartridge 1.

[0033] Deep filtration: After preliminary filtration, when the liquid level in the first filter cartridge 1 rises to the height of the overflow pipe 3, it flows through the overflow pipe 3 into the second filter cartridge 7, which is connected to it. The second filter cartridge 7 is filled with activated carbon rods as the second filter material 10. The activated carbon rods have a rich microporous structure, which can further adsorb tiny impurities, pigments and odor substances in the solution, thereby performing deep filtration of the solution and improving the purity of the magnesium chloride solution.

[0034] Discharge: The high-purity magnesium chloride solution, after being deeply filtered by the second filter cartridge 7, flows out from the discharge pipe 9 at the bottom side of the second filter cartridge 7, which is far away from the first filter cartridge 1, thus completing the entire filtration and purification process.

[0035] Unlike traditional filtration devices that place the core filter element inside the device, this device places the stainless steel mesh cylinder 5 (containing the first filter media 6) on the cross 4 inside the first filter cylinder 1, with the upper end of the stainless steel mesh cylinder 5 protruding outward from the upper port of the first filter cylinder 1. The upper end of the second filter media 10 (activated carbon rod) also protrudes outward from the upper port of the second filter cylinder 7. This design allows the entire filtration device to be operated without stopping when cleaning or replacing the filter media. Operators can easily remove the filter media directly from the top of the filter cylinder for processing, greatly improving the convenience of maintenance. In addition, through the dual action of preliminary filtration and deep filtration, as well as the combination filtration of multiple filter cylinders, this device can more effectively remove impurities from magnesium chloride solution, improving the purity and quality of the product.

[0036] like Figure 1As shown, in some embodiments, the second filter cartridges 7 are arranged in a stepped manner. More specifically, the stepped arrangement of the second filter cartridges 7 is based on the first filter cartridge 1 and is distributed in a stepped manner with a progressively decreasing step shape along the solution flow direction. The connection position of the guide pipe 8 between adjacent second filter cartridges 7 is precisely matched with the step height difference: the guide pipe 8 interface of the previous second filter cartridge 7 is located in the upper middle part of its side wall, while the interface of the next filter cartridge is located in the lower middle part of its side wall, and the interface height is lower than the interface height of the previous filter cartridge. This design allows the solution that has undergone preliminary filtration in the previous filter cartridge to flow naturally into the next filter cartridge through the guide pipe 8 under the combined effect of its own gravity and liquid level difference. This avoids the problems of solution stagnation or poor flow that may occur in traditional horizontal arrangements. For example, when the solution flows from the first second filter cartridge 7 into the second, the water pressure formed by the liquid level difference can make the solution pass evenly through the activated carbon rod in the second filter cartridge, improving the uniformity of filtration. The stepped arrangement extends the filtration path of the solution, allowing the solution more time to contact the second filter material 10 (activated carbon rod) as it flows through multiple filter cartridges.

[0037] like Figure 1 As shown, in some embodiments, the number of second filter cartridges 7 is at least three. More specifically, three or more second filter cartridges 7 can better leverage the advantages of the stepped arrangement in extending the filtration path and increasing the contact time. The total filtration path length of three filter cartridges is greater than that of two filter cartridges, and the contact time between the solution and the activated carbon rod is also longer, allowing for more thorough adsorption and filtration. If the number is too small, the effect of extending the path and increasing the time will be greatly reduced, and the advantages of the stepped arrangement cannot be fully realized, thus affecting the overall filtration effect.

[0038] like Figure 1 As shown, in some embodiments, the bottom end of the first filter cartridge 1 is conical and connected to the first discharge pipe 11. The bottom of the second filter cartridge 7 is connected to the second discharge pipe 12. Discharge valves are installed on the pipe bodies of the first discharge pipe 11 and the second discharge pipe 12. More specifically, impurities accumulated at the bottom of the first filter cartridge 1 during the filtration process can be discharged through the first discharge pipe 11 by opening the discharge valve on the first discharge pipe 11. Similarly, impurities accumulated at the bottom of the second filter cartridge 7 can be discharged through the second discharge pipe 12 by opening the discharge valve on the second discharge pipe 12.

[0039] like Figure 1As shown, in some embodiments, a manifold 13 is also included. The first discharge pipe 11 and the second discharge pipe 12 are both connected to the manifold 13. More specifically, during the magnesium chloride purification and filtration process, some larger particles of precipitated impurities will accumulate at the bottom of the first filter cartridge 1 and be discharged through the first discharge pipe 11; a certain amount of impurities will also accumulate at the bottom of each second filter cartridge 7 and be discharged through the second discharge pipe 12. Without the manifold 13, the impurities discharged from these discharge pipes would need to be collected and processed separately, resulting in scattered impurity collection points. With the manifold 13, the impurities discharged from all discharge pipes can be collected in the manifold 13, achieving centralized collection of impurities. In this way, the staff only needs to set up a collection container at the outlet of the manifold 13 to collect all impurities uniformly, avoiding the situation of impurities scattering everywhere and maintaining a clean production environment.
