Abstract
Description
Technical Field
[0001] This invention belongs to the field of substrate glass production technology, and in particular to a magnetic grid device and its working method for adjusting the spacing of magnetic rods and quickly cleaning iron powder. Background Technology
[0002] In glass manufacturing, filtration is a crucial step in ensuring glass quality. Its core purpose is to remove impurities from raw materials, thereby improving their purity and ultimately guaranteeing the quality of the final glass product. Magnetic grating, currently the most suitable filtration process, is used in the glass manufacturing process. Because some iron filings are present in the raw materials, a magnetic grating with a fixed spacing between the magnetic rods attracts these iron filings during feeding. Specifically, the magnetic grating creates a specific magnetic field by fixing the spacing between the magnetic rods. When the raw material passes through, the iron filings are attracted to the grating under the influence of the magnetic field, thus removing iron filings and improving the purity of the raw materials. However, with continuous feeding, excessive accumulation of iron powder on the magnetic grating can prevent further removal of iron powder, resulting in low raw material purity and affecting glass quality.
[0003] Currently, magnetic gratings generally come in two shapes: rectangular and circular. The industry predominantly uses rectangular magnetic gratings. However, in practical applications, the shape of the discharge port limits the application of rectangular magnetic gratings, so circular magnetic gratings generally have a wider range of applications than rectangular ones. Rectangular magnetic gratings allow for adjustment of the spacing between the magnetic rods, thereby regulating the magnetic field strength. However, for circular magnetic gratings, the size of the feeding port and the surrounding space limit their ability to change the position of the magnetic rods, unlike rectangular magnetic gratings which can adjust the spacing between the rods to regulate the magnetic field strength. This makes it difficult for circular magnetic gratings to achieve optimal adsorption of iron filings under different operating conditions, failing to fully meet the diverse filtration requirements of glass manufacturing processes. Summary of the Invention
[0004] The purpose of this invention is to provide a magnetic grating device and its working method with adjustable magnetic rod spacing and rapid iron powder cleaning, solving the problem that the magnetic field strength of circular magnetic gratings cannot be adjusted in the prior art.
[0005] To achieve the above objectives, the present invention employs the following technical solution: A magnetic grid device with adjustable magnetic rod spacing for rapid iron powder removal includes an upper magnetic grid, a lower magnetic grid, and magnetic rods; The upper magnetic grating is set on top of the lower magnetic grating. The upper magnetic grating and the lower magnetic grating are rotatably connected. Several separator bars are fixedly installed inside both the upper and lower magnetic gratings. The separator bars can be detachably sleeved on the magnetic bars. The separator bars are arranged in parallel inside both the upper and lower magnetic gratings.
[0006] Furthermore, both the upper and lower magnetic gratings are circular magnetic grating structures.
[0007] Furthermore, the bottom edge of the upper magnetic grating is provided with a flange, and the top edge of the lower magnetic grating is provided with a groove, with the flange and the groove engaging.
[0008] Furthermore, a detachable rotating groove is provided between the upper magnetic grating and the lower magnetic grating, and the lower magnetic grating rotates along the rotating groove.
[0009] Furthermore, the two ends of the rotating slide are connected by a quick-release locking mechanism.
[0010] Furthermore, the separator is made of a non-magnetic metallic material.
[0011] Furthermore, a magnetic grid fixing plate is installed on the top of the upper magnetic grid, and a servo motor is fixedly installed on one side of the magnetic grid fixing plate. A gear is installed on the output end of the servo motor.
[0012] Furthermore, a rack is provided along the edge of the bottom side of the lower magnetic grating, and the rack meshes with a gear.
[0013] Furthermore, the separator bars within the upper and lower magnetic grids are arranged alternately.
[0014] A method for operating the adjustable magnetic rod spacing and rapid iron powder cleaning magnetic grid device includes: When the device is working, the magnetic rod generates a magnetic force, which attracts the iron powder in the material to the vicinity of the separator. Due to the continuous action of the magnetic force, the iron powder adsorbed around the separator will not fall off. When the device needs to be cleaned after working for a period of time, first remove the entire magnetic grid device from the working position, then pull out the magnetic rod that is fitted inside the separator. As the magnetic rod is pulled out, the magnetic force that originally acted around the separator disappears, and the iron powder that remained on the surface of the separator loses its magnetic attraction and falls off, thus completing the iron powder cleaning. After cleaning, put the magnetic rod back into the separator. When the magnetic grid spacing needs to be adjusted due to prolonged working time or uneven distribution of iron powder in the material, the lower magnetic grid is driven to rotate. Since the upper magnetic grid remains fixed, the relative positions of the upper and lower magnetic grids change during the rotation of the lower magnetic grid, which changes the magnetic field distribution of the magnetic grid on the working projection surface of the device, thereby realizing flexible adjustment of the magnetic rod spacing.
[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a magnetic grid device with adjustable magnetic rod spacing for rapid iron powder removal. Two circular magnetic grids are stacked, with the upper grid positioned on top of the lower grid. The upper and lower grids are rotatably connected; rotating either one changes the magnetic field strength. This allows for flexible adjustment of the magnetic field strength according to actual conditions, better adapting to various complex and changing working conditions and improving the adaptability and stability of the filtration process. Separating rods are fixedly installed inside both the upper and lower magnetic grids. These separating rods are detachably fitted onto the magnetic rods, allowing for rapid removal of iron powder adsorbed on them. The separating rods are arranged parallel within both the upper and lower grids, making installation and spacing adjustment more convenient and quick. This invention controls the magnetic rods' adsorption capacity for iron filings in the raw material by changing the magnetic field and rapidly removes the adsorbed iron powder. It effectively addresses changes in feeding speed and quantity, thus solving the problem of magnetic grid clogging caused by changes in feeding speed and quantity. This ensures the filtration process maintains optimal operation and significantly improves the efficiency of each step in production.
[0016] Furthermore, a non-magnetic separator is detachably fitted onto the magnetic rod, avoiding friction between the magnetic rod and the magnetic grid and converting it into sliding friction between the magnetic rod and the separator. This makes it easier to remove the magnetic rod and solves the problem of the magnetic rod being difficult to remove from the magnetic grid after it has attracted iron powder.
[0017] Furthermore, through a servo motor-gear-rack transmission mechanism, the lower magnetic grating is driven to rotate relative to the upper magnetic grating, thereby achieving dynamic adjustment of the magnetic field distribution and controllable projection area, adapting to different material iron powder distribution scenarios.
[0018] Furthermore, the two ends of the rotating chute are connected by a quick-release locking mechanism, which facilitates the installation, maintenance, and replacement of parts, thereby reducing the cost of use. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0030] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0032] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0033] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 1 The present invention provides a magnetic grid device for adjusting the spacing of magnetic rods and quickly cleaning iron powder, including a magnetic grid fixing plate 1, an upper magnetic grid 2, a rotating slide 3, a lower magnetic grid 4, a servo motor 5, a separator 6, magnetic rods 7, a gear 8 and a rack 9. The components work together to achieve the functions of adjusting the spacing of magnetic rods and quickly cleaning iron powder.
[0034] Both the upper magnetic grating 2 and the lower magnetic grating 4 are circular magnetic gratings. The upper magnetic grating 2 is positioned on top of the lower magnetic grating 4, and the two are rotatably connected. Specifically, the bottom edge of the upper magnetic grating 2 has a flange, and the top edge of the lower magnetic grating 4 has a groove. The flange and the groove cooperate to provide initial positioning for their rotation. Simultaneously, a detachable rotating slide 3 is provided between the upper magnetic grating 2 and the lower magnetic grating 4. The two ends of the rotating slide 3 are connected by a quick-release locking mechanism. Figure 6 As shown, the lower magnetic grating 4 can rotate stably along the rotating slide 3, ensuring the smoothness and reliability of the rotation process.
[0035] like Figure 2 As shown, several separator rods 6 are fixedly installed inside both the upper magnetic grid 2 and the lower magnetic grid 4. The separator rods 6 are made of non-magnetic metal to avoid interfering with the magnetic force of the magnetic rod 7 and ensure the iron powder adsorption effect. The separator rods 6 are detachably sleeved on the outside of the magnetic rod 7, and the separator rods 6 are arranged in parallel inside both the upper magnetic grid 2 and the lower magnetic grid 4. At the same time, the separator rods 6 in the upper magnetic grid 2 and the lower magnetic grid 4 are staggered, providing a structural basis for subsequent magnetic field distribution adjustment and projected area control.
[0036] like Figure 5As shown, a magnetic grid fixing plate 1 is installed on the top of the upper magnetic grid 2. The magnetic grid fixing plate 1 serves two purposes: firstly, it provides fixed support for the upper magnetic grid 2, and secondly, it provides a mounting base for the servo motor 5. A servo motor 5 is fixedly installed on one side of the magnetic grid fixing plate 1. A gear 8 is installed at the output end of the servo motor 5. A rack 9 is provided along the edge of the bottom side of the lower magnetic grid 4. The rack 9 meshes with the gear 8 to form a complete transmission mechanism, such as... Figure 3 and 4 As shown. When the servo motor 5 is working, its output end drives the gear 8 to rotate. The gear 8 drives the lower magnetic grid 4 to rotate along the rotating slide groove 3 through meshing with the rack 9.
[0037] The method of operating the adjustable magnetic rod spacing and rapid iron powder cleaning magnetic grid device of the present invention includes: Iron powder adsorption process: When the device is working, the magnetic rod 7 generates magnetic force, which attracts the iron powder in the material to the vicinity of the separator 6. Due to the continuous action of the magnetic force, the iron powder adsorbed around the separator 6 will not fall off, thus achieving effective adsorption of iron powder in the material.
[0038] Rapid iron powder cleaning process: After the device has been working for a period of time, a large amount of iron powder will accumulate around the separator rod 6, requiring cleaning. First, remove the entire magnetic grid device from the working position, and then pull out the magnetic rod 7 fitted inside the separator rod 6. As the magnetic rod 7 is pulled out, the magnetic force originally acting around the separator rod 6 disappears, and the iron powder remaining on the surface of the separator rod 6 loses its magnetic attraction and falls off, completing the iron powder cleaning. After cleaning, the magnetic rod 7 is put back into the separator rod 6, allowing the device to return to its working state. The entire iron powder cleaning process can be completed quickly and accurately in a short time.
[0039] Magnetic bar spacing adjustment process: When the working time is prolonged or the iron powder distribution in the material is uneven, and it is necessary to adjust the magnetic grid spacing to ensure appropriate magnetic force to adsorb iron powder, the servo motor 5 on one side of the magnetic grid fixing plate 1 is started. The output end of the servo motor 5 drives the gear 8 to rotate. The gear 8 drives the lower magnetic grid 4 to rotate along the rotating slide 3 through meshing with the rack 9 at the bottom of the lower magnetic grid 4. Since the upper magnetic grid 2 is fixed by the magnetic grid fixing plate 1, the relative position of the upper and lower magnetic grids changes during the rotation of the lower magnetic grid 4, and the internal separator 6 and the sleeved magnetic bars 7 are staggered, which changes the magnetic field distribution of the magnetic grid on the working projection surface of the device, thereby realizing the flexible adjustment of the magnetic bar spacing. Under this adjustment method, the variable range of the working projection area of the device is from the initial projection area S to (1 / 2)S. While effectively adjusting the magnetic field distribution to adapt to the uneven distribution of iron powder in the material, it avoids the problems of excessive projection area, excessive space occupation, and inconvenient operation when adjusting the ordinary magnetic grid.
[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
