Description

Technical Field

[0001] The present invention relates to the technical field of substrate glass processing equipment, and particularly to an iron removal device for substrate glass raw materials. Background Art

[0002] Glass substrates are key materials for electronic display devices (such as LCDs, OLEDs), and their quality directly affects the display effect. Iron impurities (Fe2+ and Fe3+) will reduce the light transmittance of the glass, resulting in color deviation and deterioration of optical properties, thereby affecting the color reproduction and brightness of the display. Therefore, controlling the iron impurity content is crucial for improving the quality of glass substrates. Iron impurities mainly come from raw materials (such as quartz sand, soda ash, limestone, etc.) and production equipment. Even if the raw materials have been preliminarily processed, they may still contain trace amounts of iron impurities. Therefore, it is necessary to further remove iron before mixing to ensure the high quality of glass substrates.

[0003] In existing raw material iron removal devices, generally, a magnet is set at the top of the conveyor belt for conveying raw materials, and the magnet is used to adsorb iron impurities in the conveyed raw materials. However, since the raw materials and iron impurities will adhere to each other in the natural state, there will be raw materials on the surface of the iron impurities during adsorption, and after the magnet surface is fully adsorbed, it is necessary to stop the machine for cleaning before reuse.

Detailed implementation manners

[0028] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0029] An iron removal device for substrate glass raw materials, as Figure 1 shown, includes a feeding component 5. A plurality of the feeding components 5 are provided. Exemplarily, three feeding components 5 are provided. The three feeding components 5 are used to convey different raw materials, and after iron removal respectively, they are mixed; specifically, as Figure 3 shown, the feeding component 5 includes a feeding hopper 51, a feeding pipe 52, a baffle 53 and a bolt 54; the bottom end of the feeding hopper 51 is connected to the feeding pipe 52, and a baffle 53 is rotatably connected at the connection between the feeding hopper 51 and the feeding pipe 52; the side part of the baffle 53 is rotatably connected to a bolt 54, and the bolt 54 is threadedly connected to the feeding pipe 52. When the substrate glass is fed, the feeding amount can be adjusted according to the type and nature of the feed; during adjustment, rotate the bolt 54 to change the length of the bolt in the feeding pipe 52, thereby changing the rotation angle of the baffle 53, changing the gap between the baffle 53 and the feeding pipe 52, and thus controlling the feeding amount of the raw material. By setting the feeding component 5 that can be adjusted according to the substrate glass raw materials, the present invention can manually control the feeding speed of the substrate glass raw materials, providing convenience for subsequent iron removal.

[0030] A plurality of the feeding components 5 are connected to a blowing component 6; the blowing component 6 is used to blow and dry the raw materials falling from the feeding component 5; as Figure 2As shown, the air blowing assembly 6 includes an outer protective housing 61, a blower 62, a heating wire 63, and a filter screen 64; the blower 62 is installed inside the outer protective housing 61, and the heating wire 63 is provided on the side of the blower 62; the outer protective housing 61 is communicated with the blanking pipe 52, and the connection between the outer protective housing 61 and the blanking pipe 52 is separated by the filter screen 64. When the substrate glass raw material is blanked, the blower 62 and the heating wire 63 are started, and hot air is formed by the blower 62 and the heating wire 63 to preheat the substrate glass raw material falling in the blanking assembly 5. At the same time, the substrate glass and iron impurities can be kept dry by heating, reducing the adhesiveness between the substrate glass raw material and the iron impurities, further facilitating the subsequent comprehensive and thorough iron removal, and at the same time avoiding taking away the raw materials during iron removal.

[0031] The bottom end of the blanking assembly 5 is provided with an iron removal assembly 7, as Figure 4As shown in the figure, the iron removal component 7 includes an iron removal box body 71, an iron attracting member, a waste iron discharge port 75 and a raw material discharge port 76; two iron attracting members are symmetrically arranged inside the iron removal box body 71, and the waste iron discharge port 75 and the raw material discharge port 76 are arranged at the bottom end and the side of the iron removal box body 71; the bottom end of the raw material discharge port 76 is communicated with the mixing component 3, and the bottom end of the mixing component 3 is connected to the support rod 4. Specifically, the iron attracting member includes a second magnet 72, a rotating sleeve 73, a rotating motor 74 and a shielding layer 77; the rotating sleeve 73 is rotatably connected inside the iron removal box body 71, and the end of the rotating sleeve 73 is connected to the rotating motor 74; a second magnet 72 and a shielding layer 77 are arranged inside the rotating sleeve 73, and the second magnet 72 and the shielding layer 77 are fixed inside the iron removal box body 71. The cross section of the rotating sleeve 73 is in a circular ring structure, and the cross sections of the second magnet 72 and the shielding layer 77 are in a semi-circular structure; a waste iron discharge port 75 is arranged at the bottom side of the end of the shielding layer 77; a raw material discharge port 76 is arranged between the two iron attracting members. That is, the top end of the rotating sleeve 73 where the second magnet 72 is arranged is communicated with the raw material discharge port 76, and the end of the rotating sleeve 73 where the second magnet 72 is not arranged is communicated with the waste iron discharge port 75; therefore, when performing iron removal, as the substrate glass raw material falls from the feeding pipe 52, the two second magnets 72 are magnetized. When the rotating motor 74 starts to rotate, due to the adsorption of the second magnet 72, the iron impurities can be driven to adsorb on the surface of the rotating sleeve 73. After the rotating sleeve 73 rotates half a circle, due to the continuous rotation of the rotating sleeve 73 and the shielding layer 77, the iron impurities lose the attraction to the second magnet 72 and fall into the waste iron discharge port 75 under the inertia generated by rotation and their own weight, while the substrate glass raw material falls into the raw material discharge port 76 under the action of gravity and continues to fall. Therefore, the present invention uses the rotating rotating sleeve 73 in cooperation with the second magnet 72 to remove iron from the falling substrate glass raw material. Since there are two sets of iron attracting members, the iron impurities of the falling substrate glass raw material are removed from both sides, and the removal is more complete. At the same time, after the iron impurities are separated from the substrate glass raw material, they can be discharged through different channels to achieve separation, and cleaning can be realized without stopping the machine, and the efficiency is higher.

[0032] In order to further improve the dispersibility of the substrate glass raw material, two arc-shaped discharge ports 521 are opened at the bottom end of the feeding pipe 52, and the radian of the discharge port 521 is the same as that of the rotating sleeve 73; the discharge port 521 is located at the top end of the rotating sleeve 73. When the substrate glass falls, it falls through the arc-shaped discharge port 521 and falls onto the surface of the rotating sleeve 73. If there are iron impurities, they are closest to the second magnet 72 at this time, and the adsorption is the strongest, further improving the adsorption strength and ensuring more comprehensive impurity removal.

[0033] In order to comprehensively collect and process the removed iron impurities, a collection tank 2 is provided outside the mixing component 3, and the scrap iron discharge port 75 communicates with the collection tank 2; the bottom end of the collection tank 2 adopts an inclined structure, and the side of the collection tank 2 communicates with the crushing component 1. As Figure 6 shown, the crushing component 1 includes a crushing box 11, a connecting pipe 12, crushing rollers 13 and a crushing motor 14; an inclined connecting pipe 12 is provided on the side of the crushing box 11, and the other end of the connecting pipe 12 communicates with the bottommost end of the collection tank 2; two groups of crushing rollers 13 are provided inside the crushing box 11, and the crushing rollers 13 are connected to the crushing motor 14, and the connecting pipe 12 is located at the center of the two crushing rollers 13. In order to process the collected iron impurities and reduce the volume of the collected impurities, since the substrate glass raw materials may be mixed with relatively large iron impurities such as bolts, in order to reduce the volume, facilitate the overall collection and subsequent processing, it is necessary to preprocess the collected iron impurities. During the preprocessing, the crushing motor 14 is turned on, and the crushing rollers 13 are started to rotate by the crushing motor 14. When the crushing rollers 13 start to rotate, the relatively large iron impurities are crushed and compressed by extrusion and shearing, reducing the volume of the iron impurities.

[0034] In order to further improve the removal efficiency of iron impurities; the mixing component 3 includes a mixing box 31, an outer guard plate 32, a first magnet 33, a valve 34, an electric telescopic rod 35, a stirring motor 36, a connecting rod 37 and a rotating shaft 38; an electric telescopic rod 35 is provided on the side of the mixing box 31, and the telescopic end of the electric telescopic rod 35 is connected to the connecting rod 37; the side of the connecting rod 37 is connected to the stirring motor 36, and the stirring motor 36 is connected to the rotating shaft 38; a plurality of outer guard plates 32 are rotatably connected to the outside of the rotating shaft 38, and a first magnet 33 is provided on the side of the outer guard plate 32; a valve 34 is provided at the bottom end of the mixing box 31. The top end of the mixing box 31 adopts a structure inclined to the outside, which is convenient for iron impurities to enter the collection tank 2, and the bottom end of the mixing box 31 forms a funnel-shaped structure. In order to avoid that there are still iron impurities mixed in the raw materials during mixing and further remove them during mixing, during mixing, the stirring motor 36 is started and the first magnet 33 is made magnetic, then the stirring motor 36 mixes the raw materials during stirring, and at the same time, if there are still impurities inside, they are adsorbed on the surface of the first magnet 33. After the stirring is completed, the electric telescopic rod 35 is started. After the electric telescopic rod 35 is started, it drives the stirring motor 36, the connecting rod 37, the rotating shaft 38, the outer guard plate 32 and the first magnet 33 to rise until they are all withdrawn. When rising, the mixing box 31 squeezes the outer guard plate 32 and the first magnet 33 to make them rotate, so that the whole can be taken out of the mixing box 31, and then the iron impurities on the surface of the first magnet 33 can be removed.

[0035] The magnet in the present invention can be a permanent magnet or an electromagnet; preferably an electromagnet.

[0036] When the present invention is in use, first, the feeding amounts of each feeding component 5 are adjusted according to the types and properties of the substrate glass blanking. During the adjustment, the rotating bolt 54 is rotated to change the length of the bolt in the feeding pipe 52, thereby changing the rotation angle of the baffle 53, changing the gap between the baffle 53 and the feeding pipe 52, and thus controlling the feeding amount of the raw material. After the adjustment, each substrate glass raw material is placed in the feeding component 5. When the substrate glass raw material enters the feeding pipe 52, the fan 62 and the heating wire 63 are started, and hot air is formed by the fan 62 and the heating wire 63 to preheat the substrate glass raw material falling in the feeding component 5. When the substrate glass raw material continues to fall, it enters the iron removal component 7, making the two magnets II 72 magnetized. When the rotating motor 74 starts to rotate, due to the adsorption of the magnet II 72, the iron impurities are driven to be adsorbed on the surface of the rotating sleeve 73. After the rotating sleeve 73 rotates half a circle, due to the continuous rotation of the rotating sleeve 73 and the shielding layer 77, the iron impurities lose the attraction to the magnet II 72 and fall at the scrap iron feeding port 75 under the inertia generated by the rotation and their own weight, while the substrate glass raw material falls into the raw material feeding port 76 under the action of gravity and continues to fall. When the raw material enters the mixing box 31, the stirring motor 36 is started and the magnet I 33 is magnetized. Then, when the stirring motor 36 stirs, the raw materials are mixed. At the same time, if there are still impurities inside, they are adsorbed on the surface of the magnet I 33. After the stirring is completed, the electric telescopic rod 35 is started. After the electric telescopic rod 35 is started, it drives the stirring motor 36, the connecting rod 37, the rotating shaft 38, the outer protection plate 32 and the magnet I 33 to rise until they are all withdrawn. When rising, the mixing box 31 extrudes the outer protection plate 32 and the magnet I 33 to make them rotate, so that the whole can be taken out of the mixing box 31. Subsequently, the iron impurities on the surface of the magnet I 33 can be removed. The iron impurities all enter the crushing box 11 through the collection tank 2. The crushing motor 14 is turned on, and the crushing roller 13 is rotated by the crushing motor 14. When the crushing roller 13 starts to rotate, the larger iron impurities are crushed and compressed by extrusion and shearing to reduce the volume of the iron impurities.

[0037] The iron removal device of the present invention can control the feeding speed when mixing the substrate glass raw materials, preheat the substrate glass raw materials falling in the feeding component at the same time, and can keep the substrate glass and iron impurities dry by heating, reduce the adhesiveness between the substrate glass raw materials and the iron impurities, further facilitate the subsequent comprehensive and thorough iron removal, and avoid taking away the raw materials during iron removal.

[0038] The iron removal component of the present invention uses a rotating iron attracting member. Since there are two groups of iron attracting members, the iron impurities in the substrate glass raw materials falling from both sides are removed, and the removal is more complete. At the same time, after the iron impurities and the substrate glass raw materials are separated, they can be discharged through different channels to achieve separation, and the cleaning can be realized without stopping the machine, and the efficiency is higher.

[0039] A magnet is also provided inside the mixing component of the present invention. When mixing, the magnet can be fully contacted with the raw materials in the mixing tank through stirring, so as to adsorb the possible iron impurities in the raw materials, thereby realizing the integration of stirring and impurity removal, further improving the iron removal efficiency and the quality of the produced glass.
