Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically relating to a magnetic iron removal filter. Background Technology

[0002] Existing power plants often install magnetic purification devices before the condensate enters the heater. These devices consist of multiple magnetic rods within a filter frame to remove iron oxidation and corrosion products from the condensate, effectively purifying the water by removing iron. However, in existing magnetic purification devices, the magnetic rods are often fixed to the filter frame. To maximize iron removal capacity, a large number of rods are densely packed. This arrangement presents several drawbacks when periodically cleaning iron impurities: the densely packed rods attract iron impurities, making them difficult to remove, especially those located inside the device. Over time, this accumulation of iron impurities negatively impacts the device's iron removal capacity and increases water flow resistance. Therefore, we have designed and proposed a magnetic iron removal filter. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where iron impurities are difficult to remove, and to propose a magnetic iron removal filter. This magnetic iron removal filter improves the filtration effect on iron impurities, facilitates filter cleaning, reduces the number of magnetic rods, and lowers manufacturing costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetic iron removal filter is designed, comprising a frame, which is a rectangular frame. Multiple rows of first and second magnetic rods are arranged in an array at intervals within the frame. Adjacent first and second magnetic rods are staggered to form a triangular layout. A vertical column is provided at one end of the frame, and a baffle is provided at the other end. The two ends of the first and second magnetic rods are movably connected to the column and the baffle. A guide plate is provided between adjacent second magnetic rods, with a gap between the guide plate and the second magnetic rod. The front ends of two adjacent guide plates are connected and fixedly fitted with a magnetizing plate, which is in contact with the first magnetic rod.

[0006] Furthermore, the column and the baffle are respectively provided with mounting through holes that are adapted to the size of the holes of the first magnetic rod and the second magnetic rod, and the first magnetic rod and the second magnetic rod are inserted into the mounting through holes.

[0007] Furthermore, the cross-sections of two adjacent guide plates are triangular, and their ends are fixedly connected to the magnetization plate.

[0008] Furthermore, the magnetizing plate has a semi-circular cross-section, and its inner diameter is the same as that of the first magnetic rod.

[0009] Furthermore, both the first and second magnetic rods are mounted on a fixed base at one end of the baffle, and a handle is rotatably connected to the fixed base.

[0010] The magnetic iron removal filter proposed in this utility model has the following advantages: it can improve the filtration effect on iron impurities, facilitate filter cleaning, reduce the number of magnetic rods, and lower manufacturing costs. Specifically:

[0011] (1) By setting a guide plate assembly in the filter, the medium flowing through it can be closer to the magnetic rod, so that it can better remove iron impurities in the medium. At the same time, after the guide plate is magnetized, it can adsorb iron impurities in the medium, increasing the adsorption area for iron impurities, thereby improving the filtration effect of iron impurities. In addition, by setting the triangular layout of the magnetic rod and the guide plate, the number of magnetic rods used can be reduced, thus reducing the cost of filter manufacturing.

[0012] (2) This utility model facilitates the cleaning of iron impurities. The magnetic rod is installed and removed by a side-plugging method. When it is necessary to clean the iron impurities on the magnetic rod, simply pull out the magnetic rod. At this time, the iron impurities on the iron rod will be peeled off and remain on the baffle. After all the magnetic rods are pulled out, the iron impurities in the frame lose the magnetic attraction, making them easier to remove. Attached Figure Description

[0022] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] See Figures 1-4A magnetic iron removal filter includes a frame 1, which is rectangular. Multiple rows of first magnetic rods 3 and second magnetic rods 4 are arranged in a spaced-out array within the frame 1. A vertical column 11 is located at one end of the frame 1, and a baffle 12 is located at the other end. The two ends of the first magnetic rods 3 and 4 are movably connected to the column 11 and the baffle 12 by a plug-in method. Mounting through holes 2, matching the diameter of the first magnetic rods 3 and 4, are provided at corresponding positions on the column 11 and the baffle 12. The first magnetic rods 3 and 4 are inserted into the mounting through holes 2. The magnetic rods are installed and removed by a lateral plug-in method. When it is necessary to clean iron impurities from the magnetic rods, simply pull out the first magnetic rods 3 and 4. The iron impurities adsorbed on the first magnetic rods 3 and 4 will be peeled off by the baffle 12 and remain on the baffle 12. After all the magnetic rods are removed, the iron impurities within the frame 1 lose their magnetic attraction and can be easily removed using a high-pressure water gun or brush. To facilitate the extraction of the first magnetic rod 3 and the second magnetic rod 4, a fixing seat 6 is installed at one end of the first magnetic rod 3 and the second magnetic rod 4 located on the baffle 12, and a handle 7 is rotatably connected to the fixing seat 6.

[0024] The first magnetic rod 3 and two second magnetic rods 4 are staggered to form a triangular layout. This triangular layout increases the interception surface for iron impurities in the medium and facilitates the installation of the flow guiding components. Iron flow guiding plates 5 are placed between adjacent second magnetic rods 4, with gaps between them. The cross-sections of two adjacent flow guiding plates 5 are triangular. Under the guidance of the flow guiding plates 5, the medium flows close to the second magnetic rods 4, allowing for better removal of iron impurities. Magnetizing plates 51 are fixedly connected to the front ends of two adjacent flow guiding plates 5. The ends of the flow guiding plates 5 are fixedly connected to the magnetizing plates 51, which are in contact with the first magnetic rods 3. Under the action of the magnetizing plates 51, the flow guiding plates 5 are magnetized, attracting iron impurities in the medium. To increase the contact area between the magnetizing plates 51 and the first magnetic rods 3, the cross-section of the magnetizing plates 51 is semi-circular, with an inner diameter the same as the diameter of the first magnetic rods 3. After the guide plate 5 is magnetized, it can adsorb iron impurities in the medium, increasing the adsorption area for iron impurities and thus improving the filtration effect of iron impurities. In addition, the triangular arrangement of the first magnetic rod 3 and the second magnetic rod 4, as well as the setting of the guide plate 5, can reduce the number of magnetic rods used, thereby reducing the cost of filter manufacturing.

[0025] This novel magnetic iron removal filter improves the filtration efficiency for iron impurities, facilitates filter cleaning, reduces the number of magnetic rods, and lowers manufacturing costs. Specifically, in use, the first magnetic rod 3 and the second magnetic rod 4 are inserted into the frame 1 with their corresponding mounting holes 2, thus completing the assembly of the magnetic iron removal filter. Arranging the magnetic iron removal filter around the condenser outlet, when condensate passes through this flow field, impurities in the water are filtered out, achieving water purification. This significantly improves condensate quality, accelerates unit start-up, saves unit operating costs, reduces energy consumption, and protects the long-term safe operation of the unit. When the magnetic iron removal filter needs to be cleaned after a period of operation, simply remove the magnetic iron removal filter and pull out the first magnetic rod 3 and the second magnetic rod 4 from the side through the handle 7. When pulling them out, the iron impurities on the first magnetic rod 3 and the second magnetic rod 4 are stripped off by the baffle 12 and remain on the baffle 12. After all the magnetic rods are removed, use a high-pressure water gun or brush to remove the iron impurities in the frame 1. Then reinstall the first magnetic rod 3 and the second magnetic rod 4 and place the magnetic iron removal filter back at the condenser outlet.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. The magnetic iron removal filter can also be installed in the exhaust system of an air-cooled unit, as well as in the oil tank of the main unit, auxiliary unit, induced draft fan, or turbine, to create a closed filtration flow field within the condensate system or oil system. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
