Description

Technical Field

[0001] The utility model belongs to the technical field of iron removal from cullet, and in particular relates to a grid type iron remover. Background Art

[0002] In the glass substrate industry, cullet is a crucial component of the raw materials used in the batching process. Untreated, non-glass impurities in cullet, especially impurities like iron filings, can directly impact the quality of the subsequent glass produced. Therefore, cullet processing typically includes a de-ironing step. Currently, de-ironing cullet involves installing a grid-type de-ironing device at a certain point along the cullet conveyor path. This device features a grid-like structure composed of multiple stainless steel tubes, with magnetic rods installed inside to provide magnetic force. As cullet is conveyed from top to bottom through the grid-type de-ironing device, the iron filings adhere to the surface of the tubes due to magnetic attraction, thereby removing the iron. Currently, the tubes and magnetic rods of a grid-type de-ironing device are generally cylindrical, and adjacent tubes require a suitable spacing to ensure unobstructed cullet flow. Therefore, while the overall dimensions of the grid-type de-ironing device are fixed, the sizes of the tubes and magnetic rods that can be set, as well as their de-ironing effectiveness, are limited, making it difficult to meet the increasingly demanding de-ironing requirements of production lines. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a grid type iron remover with better iron removal effect.

[0004] The content of the utility model includes a middle sleeve and an edge sleeve, and magnetic bars are arranged inside the middle sleeve and the edge sleeve. The middle sleeve includes a top surface, a bottom surface and two parallel side surfaces. The middle part of the top surface bulges upward to form a spire, and the spire is arranged along the length direction of the middle sleeve. The parts of the top surface located on both sides of the spire form two guide sliding surfaces one respectively. There are two edge sleeves, and the middle sleeve is arranged between the two edge sleeves. The middle sleeve is arranged parallel to the two edge sleeves and is connected by a connecting plate, and the two edge sleeves are inclined toward the side of the middle sleeve to form a guide sliding surface two.

[0005] Furthermore, the distance between the top surface and the bottom surface of the middle sleeve is greater than the distance between the two side surfaces.

[0006] Furthermore, the wall thickness of the central sleeve in the tip area is greater than the wall thickness of other areas of the central sleeve.

[0007] Furthermore, the cross-section of the tube hole of the middle sleeve is a rectangle, the width direction of the rectangle corresponds to the direction of the line between the two side plates, and the length direction of the rectangle corresponds to the direction of the connection between the top plate and the side surface. The cross-section of the magnetic rod located inside the middle sleeve is a rectangle of matching size.

[0008] Furthermore, the angle of the spire is 130°.

[0009] Furthermore, the cross section of the tube hole of the edge sleeve is rectangular, the length direction of the rectangle is parallel to the second guide sliding surface, and the top of the edge sleeve is a plane. The cross section of the magnetic rod inside the edge sleeve is a rectangular with matching size.

[0010] Furthermore, an extension surface is provided on the bottom of the edge sleeve on the side where the second guide sliding surface is located, extending downward.

[0011] Furthermore, the middle sleeve and the edge sleeve are both made of stainless steel.

[0012] Furthermore, it also includes a pull plate, one end of the middle sleeve and the edge sleeve is closed and the other end is open, the pull plate is located at the open end of the middle sleeve and the edge sleeve, and one end of the magnetic rods located inside the middle sleeve and the edge sleeve are connected to the pull plate.

[0013] Furthermore, a handle is provided on one end of the pull plate away from the middle sleeve and the edge sleeve.

[0014] The beneficial effect of the present invention is that, compared with the sleeve with a cylindrical cross-section, the cross-sectional area of ​​the middle sleeve is larger and the internal space area is larger under the condition of the same width dimension. A magnetic rod with a larger cross-sectional area can be provided to increase the magnetic force and improve the iron removal effect. Due to the setting of the top surface structure of the middle sleeve, when the broken glass falls on the spire, on the one hand, it can have a secondary crushing effect under the mutual impact with the spire, further reducing the particle size of the broken glass, which is more conducive to the further processing of the broken glass in the subsequent process. On the other hand, the two guide sliding surfaces on both sides of the spire can be used to guide the downward movement of the broken glass, increasing the contact area with the middle sleeve during the falling process of the broken glass. At the same time, the edge sleeve uses the guide sliding surface 2 to increase the contact area with the broken glass during the falling process, thereby increasing the action time and effectiveness of adsorbing iron filings and further improving the iron removal effect. Therefore, compared with the grid-type iron remover with a cylindrical sleeve, the present invention has a better iron removal effect when applied to the same broken glass conveying path, and can better meet the increasingly high iron removal requirements of the production line.

[0019] like Figure 1-Figure 3 As shown, the utility model provides a grid type iron remover, including a middle sleeve 1 and an edge sleeve 2, both of which are provided with magnetic bars. The middle sleeve 1 includes a top surface, a bottom surface and two side surfaces, which are arranged in parallel. The top surface of the middle sleeve 1 is specifically the side of the middle sleeve 1 facing upstream in the direction of feeding cullet. Figure 3 The top of the middle sleeve 1 is the top surface, the bottom is the bottom surface, and the left and right sides are the two side surfaces. Figure 3 When the perspective shown is applied to the iron removal of cullet, the conveying direction of the cullet is from top to bottom, i.e. Figure 3 The upper middle portion is upstream in the direction of cullet conveyance. The center portion of the top surface bulges upward to form a peak 11, which extends along the length of the central sleeve 1. This means the top surface of the central sleeve 1 forms an inverted V-shape. The portions of the top surface located on either side of the peak 11 form two corresponding guide surfaces 12. Two edge sleeves 2 are provided. The central sleeve 1 is positioned between the two edge sleeves 2. The central sleeve 1 is parallel to the two edge sleeves 2 and connected via a connecting plate 3, forming a grid-like structure. The two edge sleeves 2 are inclined toward the central sleeve 1, specifically, tilted downward toward the central sleeve 1, forming guide surfaces 21.

[0020] Since the edge sleeve 2 is located at the edge of the grid-type iron remover, when the broken glass is transported from top to bottom, the top surface of the middle sleeve 1 mainly bears the impact, and the impact on the edge sleeve 2 is relatively small. Based on the above-mentioned structural setting, the cross-section of the middle sleeve 1 is a polygon with two parallel side surfaces and a pointed upward protrusion. When the width dimensions are the same, the cross-sectional area of ​​the middle sleeve 1 is larger and the internal space area is larger than that of the sleeve with a cylindrical cross-section. Therefore, when the overall external dimensions of the grid-type iron remover, the spacing between adjacent sleeves and the material of the magnetic rod remain unchanged, a magnetic rod with a larger cross-sectional area can be provided to increase the magnetic force and improve the iron removal effect. At the same time, due to the setting of the top surface structure of the middle sleeve 1, when the broken glass falls on the pointed top 11, on the one hand, it can have a secondary crushing effect under the mutual impact with the pointed top 11, further reducing the particle size of the broken glass, which is more conducive to further processing of the broken glass in subsequent processes. On the other hand, the two guide sliding surfaces 12 on both sides of the pointed top 11 can be used to guide the downward movement of the broken glass, thereby increasing the contact area of ​​the broken glass with the middle sleeve during the falling process. At the same time, the edge sleeve 2 uses the guide sliding surface 21 to increase the contact area with the broken glass during the falling process, thereby increasing the action time and effectiveness of adsorbing iron chips, and further improving the iron removal effect. Therefore, compared with the grid-type iron remover with a cylindrical sleeve, the utility model has a better iron removal effect when applied to the same cullet conveying path, and can better meet the increasingly high iron removal requirements of the production line.

[0021] The distance between the top surface and the bottom surface of the middle sleeve 1 is greater than the distance between the two side surfaces, so that the width of the middle sleeve 1 will not be increased while the cross-sectional area of ​​the middle sleeve 1 is increased.

[0022] like Figure 3 As shown, the wall thickness of the central sleeve 1 in the peak 11 region is greater than that in other regions of the central sleeve 1, i.e., the peak 11 region of the central sleeve 1 is additionally thickened. Since the top surface of the central sleeve 1 primarily bears the impact when cullet is transported from top to bottom, this configuration enhances the impact resistance of the top surface of the central sleeve 1, improving its strength and wear resistance, and prolonging the time it takes for the top surface of the central sleeve 1 to break due to impact, thereby extending its service life and reliability.

[0023] The central sleeve 1 has a rectangular cross-section, with the width of the rectangle corresponding to the line connecting the two side panels and the length of the rectangle corresponding to the connection between the top panel and the side panels. The magnetic rod inside the central sleeve 1 has a rectangular cross-section of matching dimensions. Compared to cylindrical magnetic rods, its cross-section is larger, resulting in greater magnetic force and improved iron filings absorption. This arrangement creates a thickened, triangular top surface, with the peak 11 positioned at the rear, effectively resisting impact damage.

[0024] The angle of the pointed top 11 is preferably 130 degrees, that is, the included angle between the guide surfaces 12 on both sides of the pointed top 11 is 130 degrees. This arrangement not only ensures secondary crushing of the cullet, but also prevents the cullet from sliding down too quickly due to an excessively steep slope of the guide surface 12. This allows the cullet to slide more smoothly along the guide surface 12, effectively absorbing the iron filings.

[0025] The edge sleeve 2 preferably has a rectangular cross-section, with the length of the rectangle parallel to the second guide surface 21. The magnetic bar inside the edge sleeve 2 has a rectangular cross-section of matching dimensions. Compared to a cylindrical magnetic bar, this has a larger cross-section, greater magnetic force, and better iron filings adsorption. Furthermore, the distance between the surface of the magnetic bar inside the edge sleeve 2 and the second guide surface 21 is consistent, ensuring that the second guide surface 21 can generate sufficient adsorption force. The top of the edge sleeve 2 is flat, reducing edge blind spots and preventing broken glass from getting stuck.

[0026] In one configuration of the present invention, Figure 3 As shown, the bottom of the edge sleeve 2 where the second guide sliding surface 21 is located is provided with an extension surface extending downward, so as to further increase the contact area of ​​the broken glass during the falling process.

[0027] The central sleeve 1 and edge sleeves 2 are both made of stainless steel, which offers excellent strength and resists rust. The bottom and two side surfaces of the central sleeve 1 are preferably 3 mm thick, while the side of the edge sleeve 2 where the guide surface 21 is located is preferably 3 mm thick or greater, to ensure high structural strength for the central sleeve 1 and edge sleeve 2. The number of central sleeves 1 can be one or more depending on actual needs.

[0028] The present invention also includes a pull plate 4. One end of the middle sleeve 1 and the edge sleeve 2 is closed, and the other end is open. The pull plate 4 is located at the open end of the middle sleeve 1 and the edge sleeve 2. One end of the magnetic rods located inside the middle sleeve 1 and the edge sleeve 2 is connected to the pull plate 4, that is, all the magnetic rods are set on the pull plate 4 and inserted into the corresponding middle sleeve 1 and the edge sleeve 2. The pull plate 4 is provided with a handle 5 at the end facing away from the middle sleeve 1 and the edge sleeve 2, which is more convenient for the operator to hold and perform the corresponding pulling and pulling operations. When the grid-type iron remover of the present invention is used, it can be directly set in a vertical pipe for conveying cullet, or it can be set in an iron removal box for connecting the cullet conveying pipe. The installation method during setting is the same as that of the prior art and will not be repeated here. In specific applications, one or more can be selectively set according to actual needs.
