Description

Technical Field

[0001] This utility model relates to the field of photothermal ultra-clear glass production technology, specifically a device for reducing the iron content in photothermal ultra-clear glass raw materials. Background Technology

[0002] In the current production of ultra-clear float glass, the increased iron content in the raw materials leads to a decrease in the transmittance of ultra-clear glass sheets across the entire wavelength range, which fails to meet the standards for ultra-clear glass sheets. Therefore, it is necessary to remove iron impurities from the glass raw materials.

[0003] Currently, common methods for removing iron impurities in the pretreatment stage of glass raw materials mainly include physical magnetic separation and chemical acid washing. Physical magnetic separation typically uses strong magnetic rods, magnetic drums, or permanent magnet separators to adsorb magnetic iron impurities in the raw materials using magnetic fields. However, in practical applications, existing magnetic separation methods suffer from incomplete treatment and low efficiency; the material only passes through the magnetic separation zone once, making it difficult to fully capture and remove iron impurities below the surface.

[0004] Therefore, there is an urgent need to design a device that can deeply remove iron impurities from raw materials to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To address the existing problems, this utility model provides a device for reducing the iron content in photothermal ultra-white glass raw materials, thereby solving the problems mentioned in the background art where the existing magnetic separation method has incomplete processing, low efficiency, and the material only passes through the magnetic separation area once, making it difficult to fully capture and remove iron impurities below the surface.

[0006] To address the existing problems, this utility model provides a device for reducing the iron content in photothermal ultra-clear glass raw materials, including a frame. A support arm is fixedly connected to the lower end of the frame. A pair of main rollers are arranged at both ends inside the frame, with both ends of the main rollers rotatably connected to the side walls of the frame. Multiple support rollers are arranged between the two main rollers, with both ends of the support rollers rotatably connected to the side walls of the frame. A conveyor belt is sleeved around the main rollers, and the support rollers roll in contact with the lower surface of the upper layer of the conveyor belt. Two sets of scraping and suction assemblies are arranged at the upper end of the frame, with a material-turning assembly between the two sets of scraping and suction assemblies. Multiple U-shaped frames are arranged on both sides of the scraping and suction assemblies at the upper end of the frame. Baffles are fixedly connected to the inner side walls of the U-shaped frames, with the lower edges of the baffles sliding in contact with the upper surface of the conveyor belt. The end of one main roller at one end of the frame is fixedly connected to the output shaft of a reduction motor, which is mounted on the side wall of the frame.

[0007] Furthermore, the scraping and suction assembly includes a support frame fixedly connected to the upper end of the frame, a scraper and a magnetic plate are slidably installed inside the support frame, and the scraper and the magnetic plate are fixedly connected by a connecting block; a lead screw is rotatably connected to the middle of the upper end of the support frame, the lower end of the lead screw is rotatably connected to the upper end of the scraper, and a torsion nut is installed at the upper end of the lead screw.

[0008] Furthermore, the scraping and suction assembly also includes a limiting slider fixed to the side of the scraper, the limiting slider being slidably connected in the limiting groove of the slide rail, and the upper end of the slide rail being fixedly connected to the upper end of the support frame.

[0009] Furthermore, the two side walls of the support frame are provided with a first through groove and a second through groove, and the upper side ends of the scraper and the magnet plate are slidably connected in the first through groove and the second through groove, respectively.

[0010] Furthermore, the material turning assembly includes a rotating shaft rotatably connected to the side end of the frame. One end of the rotating shaft is fixedly connected to one end of the main roller, and the other end is fixedly connected to a drive pulley. A driven pulley is also rotatably connected to the side end of the frame, and it is connected to the drive pulley via belt drive. A drive gear is fixedly connected to the coaxial end of the driven pulley, and a driven gear meshes above the drive gear. The driven gear is fixedly installed at one end of the rotating shaft. The rotating shaft is installed above the frame through a bearing seat, and a lever is radially fixedly connected to it.

[0011] Furthermore, both the main roller and the support roller are ceramic rollers.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The first set of scraping and suction components of this utility model first scrapes and absorbs iron impurities on the surface of the raw material. The turning component turns the raw material by turning the lever, turning the deep untreated part to the surface. Then, the second set of scraping and suction components adsorbs it again, realizing the deep removal of iron impurities and effectively reducing the iron content in the raw material.

[0014] 2. This utility model, by setting up a scraping and suction assembly, can drive the lead screw to move the scraper and the suction plate up and down by twisting the torsion nut of the scraping and suction assembly. Combined with the guiding effect of the limit slider and the slide rail, the distance between the scraper, the suction plate and the upper surface of the conveyor belt can be adjusted. It can be adapted to glass raw materials of different thicknesses and particle sizes. It is easy to operate and has a wide range of applications.

[0015] 3. The power source of the material turning component of this utility model is directly from the main roller. When the main roller rotates, it can synchronously drive the rotating shaft to rotate, which in turn drives the drive pulley, the driven pulley connected by the belt drive, and the drive gear coaxial with the driven pulley in sequence. The drive gear then meshes with the driven gear to drive the rotating shaft to rotate, and finally makes the lever on the rotating shaft rotate to realize the turning of the raw material. This design does not require the addition of an independent drive component. Attached Figure Description

[0025] The scraping and suction assembly 6 includes a support frame 601 fixedly connected to the upper end of the frame 1. A scraper 602 and a magnet 603 are slidably installed inside the support frame 601. The scraper 602 and the magnet 603 are fixedly connected by a connecting block 604. A lead screw 605 is rotatably connected to the middle of the upper end of the support frame 601. The lower end of the lead screw 605 is rotatably connected to the upper end of the scraper 602. A torsion nut 606 is installed on the upper end of the lead screw 605.

[0026] The scraping and suction assembly 6 also includes a limiting slider 607 fixed to the side of the scraper 602. The limiting slider 607 is slidably connected in the limiting groove of the slide rail 608. The upper end of the slide rail 608 is fixedly connected to the upper end of the support frame 601.

[0027] The support frame 601 has a first through groove 6011 and a second through groove 6012 on both sides, and the upper side ends of the scraper 602 and the magnet plate 603 are slidably connected in the first through groove 6011 and the second through groove 6012 respectively.

[0028] It should be noted that the magnet plate 603 has an integrated electromagnetic device at the lower end for adsorbing iron impurities. The electromagnetic device is existing technology, and its structure and principle will not be described in detail.

[0029] The material turning assembly 7 includes a rotating shaft 701 rotatably connected to the side of the frame 1. One end of the rotating shaft 701 is fixedly connected to one end of the main roller 3, and the other end is fixedly connected to a drive pulley 702. A driven pulley 703 is also rotatably connected to the side of the frame 1, and it is connected to the drive pulley 702 via a belt 704. A drive gear 705 is fixedly connected to the coaxial end of the driven pulley 703. A driven gear 706 meshes above the drive gear 705. The driven gear 706 is fixedly installed on one end of the rotating shaft 707. The rotating shaft 707 is installed above the frame 1 via a bearing seat 708, and a lever 709 is fixedly connected to it radially.

[0030] Both the main roller 3 and the support roller 4 are ceramic rollers.

[0031] Working principle: Before operation, use a wrench to turn the torsion nut 606 at the upper end of the support frame 601 to drive the lead screw 605 to rotate, thereby driving the scraper 602 to move. The limiting slider 607 on the side of the scraper 602 slides in the limiting groove of the slide rail 608, and the upper side ends of the scraper 602 and the magnet 603 slide in the first through groove 6011 and the second through groove 6012 on the two side walls of the support frame 601, respectively, to ensure that the scraper 602 and the magnet 603 are smoothly adjusted to the correct position, and the distance between the lower end of the scraper 602 and the magnet 603 and the upper surface of the conveyor belt 5 is adjusted appropriately.

[0032] During operation, the geared motor 10 installed on the side wall of the frame 1 is started first. Its output shaft drives the main roller 3 fixedly connected to it to rotate. The main roller 3 drives the conveyor belt 5 to run. The support roller 4 between the two main rollers 3 rolls in contact with the lower surface of the upper belt of the conveyor belt 5, providing support for the conveyor belt 5 to ensure smooth conveying. At the same time, the baffle 9 on the inner side wall of the U-shaped frame 8 on both sides of the upper scraping and suction assembly (6) of the frame 1 slides in contact with the upper belt surface of the conveyor belt 5 to prevent the raw materials from spilling from the side during conveying. When the raw material enters the first set of scraping and suction components 6 along the conveyor belt 5, the scraper 602 will scrape the raw material flat in front of the magnet plate 603. When the flattened raw material passes through the magnet plate 603, iron impurities in the raw material will be removed. Then the raw material will reach the turning component 7 along the conveyor belt 5. The rotating shaft 701 fixed at one end of the main roller 3 rotates with the main roller 3, driving the drive pulley 702 at the other end of the rotating shaft 701 to rotate. The drive pulley 702 drives the driven pulley 703 to rotate through the belt 704. The drive gear 705 at the coaxial end of the driven pulley 703 rotates accordingly. The drive gear 705 meshes with the driven gear 706 above, causing the rotating shaft 707 fixedly connected to the driven gear 706 to rotate. The lever 709 on the rotating shaft 707 rotates and turns the raw material.

[0033] Finally, the turned raw material enters the second set of scraping and suction components 6 along with the conveyor belt 5. The scraping and suction components 6 operate in the same way as the first set. The scraper 602 flattens the surface of the raw material, and the magnet 603 adsorbs the iron impurities that have just turned over, thus completing the deep removal of iron impurities from the raw material. The processed raw material continues to be transported to the subsequent process along with the conveyor belt 5.
