Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing device technology, specifically a multi-stage crushing device for crushed glass. Background Technology
[0002] Foamed glass is an inorganic non-metallic glass material made from crushed glass, foaming agent, modifiers, and foaming accelerators, which are finely ground and uniformly mixed, then melted at high temperature, foamed, and annealed. Among them, crushed glass is the main raw material, which needs to be washed, dried, and then coarsely crushed before fine grinding.
[0003] Publication number CN209205419U discloses a glass crushing device, comprising a glass crushing feeding cylinder; a glass crushing bearing body; two herringbone-shaped support blocks; and a glass crushing hammer mechanism installed inside the glass crushing bearing body. The two steel plates forming the glass crushing feeding cylinder have a height greater than 40cm, and their lower ends have bent feet that can be connected and fixed to the upper ends of the corresponding steel plates of the glass crushing bearing body via bolts. The steel plates forming the glass crushing bearing body are integrally fixed to the two herringbone-shaped support blocks using external bolts. This patent's crushing device is modularly formed; when the bolts are loosened, the two steel plates in the glass crushing feeding cylinder can be easily disassembled. When the external bolts are loosened, the four steel plates corresponding to the glass crushing device and the two herringbone-shaped support blocks can be disassembled. Therefore, this patent also has the advantage of facilitating disassembly, assembly, and storage.
[0004] However, when the crushed glass material is fed into the furnace, some metal impurities will be mixed in. The existing technology mentioned above cannot separate the metal impurities in the crushed glass material. When it enters the glass furnace, the metal impurities will accelerate the erosion of the refractory material under high temperature, shorten the life of the glass furnace and increase maintenance costs. At the same time, metal residues may cause uneven glass composition, forming bubbles or impurity defects, reducing the light transmittance and strength of the finished product, and increasing the defect rate.
[0005] Therefore, a multi-stage glass crushing device is proposed to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 - Figure 4 This embodiment of a multi-stage glass crushing device includes a conveyor 1, a primary crushing component, a secondary crushing component, a dust collection component, and a magnetic suction component. The primary crushing component, the dust collection component, and the magnetic suction component are all mounted on the conveyor 1. The secondary crushing component is mounted on one side of the conveyor 1. The magnetic suction component includes a suction cup 15. A second frame 13 is mounted on the side wall of the conveyor 1. An electric telescopic rod 14 is fixedly mounted on the upper end of the second frame 13. A lifting hook is fixedly connected to the telescopic end of the electric telescopic rod 14. A lifting ring is mounted on the upper end of the suction cup 15. The lower end of the lifting hook is connected to the lifting ring. Multiple isolation plates 2 are evenly spaced on the upper end of the conveyor 1.
[0024] After the glass shards and metal impurities are crushed together by the primary crushing assembly and fall onto the conveyor 1, they are transported by the conveyor 1 to the secondary crushing assembly. During this process, they pass through the magnetic suction assembly. The telescopic end of the electric telescopic rod 14 in the magnetic suction assembly is connected to the lifting ring through the sling hook, so that the suction cup 15 is placed downward and close to the upper surface of the conveyor 1 inside the second frame 13. The suction cup 15 can adsorb the metal impurities in the material that has been crushed by the primary crushing assembly below the second frame 13. This allows the metal impurities in the glass shards crushed by the primary crushing assembly to be removed, and then the secondary crushing assembly can perform a second crushing. This effectively avoids the presence of metal impurities in the crushed glass shards, which would cause impurities in the molten glass and reduce the defect rate of the glass shards in subsequent processing.
[0025] The primary crushing component includes a primary crushing device 4. A first mounting frame 3 is provided on one side of the conveyor 1. The primary crushing device 4 is fixedly mounted on the first mounting frame 3. Two servo motors 6 are provided on one side of the primary crushing device 4. A primary feed inlet 5 is provided at the upper end of the primary crushing device 4. Hammer rollers are fixedly connected to the output shafts of the two servo motors 6 inside the primary crushing device 4. A primary discharge outlet is provided at the lower end of the primary crushing device 4. A discharge hole 7 corresponding to the primary discharge outlet is provided at the upper end of the first mounting frame 3. An inclined guide plate 8 is fixedly connected to the lower end of the first mounting frame 3.
[0026] By setting up a primary crushing device 4, when the glass shards are fed into the primary crushing device 4 from the primary feed inlet 5, two servo motors 6 start simultaneously and drive two hammer rollers to rotate. The two hammer rollers can perform preliminary crushing of the glass shards in the primary crushing device 4, thus achieving preliminary separation of the glass shards.
[0027] The secondary crushing component includes a secondary crushing device 16. The upper end of the secondary crushing device 16 is provided with a secondary feed inlet 17, and the lower end of the secondary crushing device 16 is provided with a secondary discharge outlet. Four No. 2 servo motors 19 are fixedly installed on the secondary crushing device 16, and the output shafts of the four No. 2 servo motors 19 are located inside the secondary crushing device 16 and are all fixedly connected to crushing rollers 18.
[0028] By setting up a secondary crushing device 16, when the material is conveyed to the secondary feed inlet 17 by the conveyor 1, the broken glass material will enter the secondary crushing device 16 through the secondary feed inlet 17. At this time, four No. 2 servo motors 19 work simultaneously and make the four crushing rollers 18 rotate relative to each other in pairs, thereby realizing the secondary processing of the broken glass material in the secondary crushing device 16.
[0029] The dust collection component includes a dust collection bin 10. A frame 9 is provided on the side wall of the conveyor 1. The dust collection bin 10 is fixedly installed on the frame 9. A suction fan is provided inside the dust collection bin 10. An air duct 11 is fixedly connected to the suction end of the suction fan. The other end of the air duct 11 passes through the upper surface of the frame 9 and a dust collection head 12 is fixedly installed thereon. The dust collection head 12 is inclined inside the frame 9.
[0030] By setting up a dust collection component, a large amount of dust is generated when the primary crushing component processes and crushes the glass material. This dust is discharged onto the conveyor 1 along with the material, and then sucked into the dust collection bucket 10 by the suction fan through the air duct 11 and the dust collection head 12, which improves the dust suppression effect of the overall device and inhibits the spread of dust after processing.
[0031] Among them, the side wall of the conveyor 1 is provided with multiple threaded grooves, and the side walls of the first frame 9 and the second frame 13 are symmetrically provided with two threaded holes. The multiple threaded holes and the matching threaded grooves are all threaded with fastening bolts 20.
[0032] By opening multiple threaded grooves and threaded holes and setting fastening bolts 20, the first frame 9 and the second frame 13 can be threadedly fixed to the side wall of the conveyor 1 through the cooperation of the fastening bolts 20 with the threaded holes and threaded grooves.
[0033] Among them, suction cup 15 is a permanent magnet suction cup made of samarium cobalt material;
[0034] By using samarium cobalt material, the samarium cobalt suction cup 15 has the characteristics of corrosion resistance and high temperature resistance, which can ensure the adsorption effect on metal impurities in broken glass materials.
[0035] The inclined direction of the inclined guide plate 8 is the same as the conveying direction of the conveyor 1;
[0036] By making the inclined guide plate 8 tilt in the same direction as the conveying direction of the conveyor 1, the inclined guide plate 8 can guide the crushed glass material that has undergone preliminary processing by the primary crushing component to the same direction as the conveyor 1.
[0037] The working principle of the above embodiment is as follows: After the broken glass material and metal impurities are crushed together by the primary crushing component and fall onto the conveyor 1, they will pass through the magnetic suction component during the process of being conveyed by the conveyor 1 to the secondary crushing component. The telescopic end of the electric telescopic rod 14 in the magnetic suction component is connected to the lifting ring through the sling hook, so that the suction cup 15 is downward and close to the upper surface of the conveyor 1 inside the second frame 13. The suction cup 15 can adsorb the metal impurities in the material that has been crushed by the primary crushing component below the second frame 13, so that the metal impurities in the broken glass material crushed by the primary crushing component can be removed, and then the secondary crushing component can complete the secondary crushing. This effectively avoids the metal impurities mixed in the crushed broken glass material, which would cause impurities in the molten glass liquid and reduce the defect rate of the broken glass material in subsequent processing.
[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
