Description

Technical Field

[0001] This utility model belongs to the field of glass technology, specifically relating to a broken glass processing system. Background Technology

[0002] In the production of specialty glass, cullet is a major raw material, accounting for a significant proportion. Recycling processed glass reduces the need for raw materials, thus lowering production costs. Furthermore, using cullet helps reduce industrial waste, contributing positively to environmental protection. Therefore, the use of cullet is an economical, efficient, and environmentally friendly option in the manufacture of specialty glass.

[0003] Before being used in production, rubble glass needs to be processed through a series of crushers to obtain glass powder of the appropriate particle size. However, currently, after the rubble glass is crushed in stages, the final glass powder often has some particles that do not meet the usage requirements. In addition, recycled rubble glass easily carries iron impurities, which not only increases the wear and tear on crushers, conveyor belts, and other equipment, but also results in iron impurities in the crushed glass powder. Furthermore, iron filings and other iron impurities are easily mixed in during the glass crushing process, leading to a high iron content in the final glass powder, which affects the quality of subsequent glass production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a broken glass processing system that improves the efficiency and quality of glass powder processing and has higher operational stability.

[0005] This utility model includes a feeding device, a first crusher, a primary screening machine, a second crusher, and a secondary screening machine arranged sequentially along the glass crushing direction. It also includes a first iron remover, a second iron remover, a first conveying unit, and a second conveying unit. The first iron remover is located between the feeding device and the first crusher. The undersize product outlet of the primary screening machine faces the inlet of the second crusher, and the oversize product outlet of the primary screening machine faces one end of the first conveying unit. The other end of the first conveying unit faces either the space between the second crusher and the secondary screening machine or the space between the feeding device and the first crusher. The oversize product outlet of the secondary screening machine faces one end of the second conveying unit, and the other end of the second conveying unit faces the space between the feeding device and the first crusher. The second iron remover is used to remove iron from the glass powder discharged from the undersize product outlet of the secondary screening machine.

[0006] Furthermore, it also includes a diversion valve, a powder packaging device, and a powder storage device. The inlet end of the diversion valve is used to supply glass powder after iron removal by the second iron remover. The diversion valve includes two outlet ends, one of which is set towards the powder packaging device and the other outlet end is set towards the powder storage device.

[0007] Furthermore, the powder packaging device includes a ton bag clamping mechanism and a weighing platform. One of the outlet ends of the diversion valve is positioned facing the ton bag clamping mechanism. The ton bag clamping mechanism is used to fix the ton bag, and the weighing platform is used to weigh the ton bag containing glass powder.

[0008] Furthermore, the powder storage device includes a bucket elevator and a powder silo, with the other outlet end of the diversion valve facing the bucket elevator, which is used to deliver the glass powder discharged from the other outlet end into the powder silo.

[0009] Furthermore, a level gauge is installed inside the powder silo.

[0010] Furthermore, it also includes a first belt conveyor, a second belt conveyor, a third belt conveyor, and a fourth belt conveyor. The first belt conveyor is located between the feeding device and the first crusher. The first iron remover is located on the first belt conveyor. The second belt conveyor is located between the first crusher and the primary screening machine. The third belt conveyor is located between the second crusher and the secondary screening machine. One end of the fourth belt conveyor is located below the outlet end of the undersize product of the secondary screening machine. The second iron remover is located at the other end of the fourth belt conveyor.

[0011] Furthermore, it also includes a powder channel, which is located below the side of the fourth belt conveyor with the second iron separator, for the glass powder that has been removed by the second iron separator to fall into. The end of the powder channel is located toward or connected to the inlet end of the diversion valve.

[0012] Furthermore, it also includes an impurity channel and an impurity collection box. The roller at the other end of the fourth belt conveyor is a magnetic roller, which forms the second iron remover. The impurity channel is located below the end of the fourth belt conveyor with the second iron remover and is used to allow iron impurities adsorbed by the second iron remover on the fourth belt conveyor to fall into it. The end of the impurity channel is set towards or connected to the impurity collection box.

[0013] Furthermore, the other end of the first conveying unit is positioned between the second crusher and the secondary screening machine, and the other end of the second conveying unit is positioned between the feeding device and the first iron remover. Both the first conveying unit and the second conveying unit are chutes.

[0014] Furthermore, the feeding device includes a tilting mechanism, a buffer bin, and a vibrating feeder. The tilting mechanism is used to drive the material box containing broken glass to tilt so as to pour the broken glass into the buffer bin. The outlet end of the buffer bin is set towards the inlet end of the vibrating feeder.

[0015] The beneficial effects of this invention are as follows: It employs a two-stage screening process. The second stage ensures that the final output glass powder particle size meets requirements. The crushed glass from the first crusher undergoes a first-stage screening before entering the second crusher, removing larger particles and reducing the workload of the second crusher, as well as wear on its internal components. This improves the crushing efficiency, quality, and uniformity of the second crusher, thereby increasing the efficiency of obtaining glass powder from crushed glass and enhancing the overall stability of the system. A second iron separator is installed after the second-stage screening machine. This separator removes iron from the glass powder at the end of the processing, eliminating iron filings and other iron impurities introduced during crushing and conveying, thus reducing the final iron content and improving the quality of the glass powder. Furthermore, the first iron separator, installed before the first crusher, removes iron impurities from the crushed glass before it enters the first crusher, reducing wear on the internal components of both crushers and improving the overall stability of the system.

[0016] Therefore, this invention ensures that the particle size of the final glass powder meets the requirements while minimizing the iron content in the glass powder, thereby improving the glass powder processing efficiency and quality, and also enhancing the overall stability of the crushed glass processing system.

[0019] like Figure 1As shown, this utility model provides a glass crushing system, including a feeding device, a first crusher 7, a primary screening machine 9, a second crusher 10, and a secondary screening machine 12. The feeding device, first crusher 7, primary screening machine 9, second crusher 10, and secondary screening machine 12 are arranged sequentially along the glass crushing conveying direction, meaning that the glass crushing process involves passing through the feeding device, first crusher 7, primary screening machine 9, second crusher 10, and secondary screening machine 12 in sequence. This utility model also includes a first iron remover 6, a second iron remover, a first conveying unit 15, and a second conveying unit 16. The first iron remover 6 is located between the feeding device and the first crusher 7, and is used to remove iron from the glass crushed before it enters the first crusher 7, allowing the glass crushed before entering the first crusher 7 to undergo primary crushing.

[0020] The undersize product outlet of the screening machine is used to discharge material that has passed through the screen holes, while the oversize product outlet is used to discharge material that has not passed through the screen holes. The primary screening machine 9 is used to screen the crushed glass from the first crusher 7. The undersize product outlet of the primary screening machine 9 faces the inlet of the second crusher 10. The undersize product is discharged through its outlet and enters the second crusher 10 for secondary crushing. The product obtained after secondary crushing then enters the secondary screening machine 12 for further screening. The screen aperture of the secondary screening machine 12 is smaller than that of the primary screening machine 9. The product discharged through the undersize product outlet of the secondary screening machine 12 is glass powder that meets the particle size requirements. The second iron remover is used to remove iron from the glass powder discharged through the undersize product outlet of the secondary screening machine 12, ensuring the quality of the final output glass powder.

[0021] The oversize product outlet of the primary screening machine 9 is positioned towards one end of the first conveying unit 15, and the other end of the first conveying unit 15 is positioned between the second crusher 10 and the secondary screening machine 12, or between the feeding device and the first crusher 7. The oversize product outlet of the secondary screening machine 12 is positioned towards one end of the second conveying unit 16, and the other end of the second conveying unit 16 is positioned between the feeding device and the first crusher 7. In the primary screening machine 9 and the secondary screening machine 12, the broken glass discharged along the oversize product outlet is returned to the first crusher 7 for further crushing.

[0022] The glass crushing system provided by this utility model employs a two-stage screening process. The second-stage screening ensures that the final output glass powder particle size meets the requirements. The glass crushed by the first crusher 7 undergoes a first-stage screening before entering the second crusher 10, which removes larger particles, ensuring the feed to the second crusher 10 meets requirements, reducing the crushing workload of the second crusher 10, and minimizing wear on its internal components. This also ensures the stability and reliability of the second crusher 10's crushing operation, improving its crushing efficiency, quality, and uniformity, thereby increasing the efficiency of obtaining glass powder through glass crushing and improving the overall stability of the system. A second iron remover is installed after the second-stage screening machine 12. This second iron remover removes iron from the glass powder at the end of the processing, removing iron filings and other iron impurities mixed in during crushing and conveying, thus reducing the final iron content of the glass powder and improving its quality. Since a first iron separator 6 is installed before the first crusher 7, the first iron separator 6 can remove iron impurities mixed in the crushed glass before the crushed glass enters the first crusher 7, reduce the wear on the internal components of the first crusher 7 and the second crusher 10, and thus improve the overall stability of the system operation.

[0023] Therefore, this invention ensures that the particle size of the final glass powder meets the requirements while minimizing the iron content in the glass powder, thereby improving the glass powder processing efficiency and quality, and also enhancing the overall stability of the crushed glass processing system.

[0024] This utility model also includes a diversion valve 19, a powder packaging device, and a powder storage device. The inlet end of the diversion valve 19 is used to allow glass powder after iron removal by the second iron remover to enter. The diversion valve 19 includes two outlet ends, one of which is set towards the powder packaging device and the other outlet end is set towards the powder storage device. When the diversion valve 19 is switched to open with the outlet end facing the powder packaging device, the glass powder is conveyed towards the powder packaging device through the diversion valve 19 along the outlet end. When the diversion valve 19 is switched to open with the outlet end facing the powder storage device, the glass powder is conveyed towards the powder storage device through the diversion valve 19 along the outlet end.

[0025] The powder packaging device includes a ton bag clamping mechanism 20 and a weighing platform 21. One of the outlets of the diversion valve 19 is specifically positioned facing the ton bag clamping mechanism 20 in the powder packaging device. The ton bag clamping mechanism 20 is used to fix the bag opening of the ton bag or the hanging rope on the bag opening, thereby fixing the ton bag and keeping the bag opening open so that the glass powder conveyed to the powder packaging device falls into the ton bag. The weighing platform 21 is used to weigh the ton bags containing glass powder, which facilitates the control of the weight of glass powder in each ton bag. Here, the ton bag is the glass powder packaging bag. The ton bag clamping mechanism 20 is existing technology and is very common in various bagging equipment such as ton bag machines. Its structure will not be described in detail. The weighing platform 21 is located below the ton bag clamping mechanism 20. After the ton bag is fixed by the ton bag clamping mechanism 20, the bottom of the ton bag is located on the weighing platform 21.

[0026] The powder storage device includes a bucket elevator 22 and a powder silo 23. Specifically, the other outlet of the diversion valve 19 is positioned towards the bucket elevator 22 within the powder storage device. The bucket elevator 22 is used to deliver the glass powder discharged from this other outlet to the powder silo 23 for temporary storage. Preferably, a level gauge 24 is installed in the powder silo 23 to monitor the height of the glass powder within the silo.

[0027] In one embodiment of this utility model, the switching of the opening and closing of the outlet end of the diversion valve 19 is performed manually.

[0028] In another embodiment of this utility model, the diversion valve 19, weighing platform 21, bucket elevator 22, and level gauge 24 are electrically connected to the controller, which performs corresponding control and coordination. For example, when the diversion valve 19 is open towards the outlet end of the bucket elevator 22, if the glass powder in the powder hopper 23 fed back by the level gauge 24 has not reached the preset level, the bucket elevator 22 continues to run. If the glass powder in the powder hopper 23 fed back by the level gauge 24 has reached the preset level, the bucket elevator 22 stops running, and the diversion valve 19 switches to open towards the outlet end of the ton bag clamping mechanism 20, or the entire system pauses operation to stop glass breakage. For example, when a roller is installed on the ton bag clamping mechanism 20 and the diversion valve 19 is opened at the outlet end facing the ton bag clamping mechanism 20, if the weight fed back by the weighing platform 21 is less than the preset weight, the diversion valve 19 remains open and continues to feed glass powder into the current ton bag. When the weight fed back by the weighing platform 21 reaches the preset weight, the diversion valve 19 switches to open at the outlet end facing the bucket elevator 22, and the bucket elevator 22 starts at the same time, or the entire system stops running to stop glass breakage.

[0029] This utility model also includes a first belt conveyor 5, a second belt conveyor 8, a third belt conveyor 11, and a fourth belt conveyor 13. The first belt conveyor 5 is located between the feeding device and the first crusher 7, and is used to convey broken glass to the first crusher 7. The first iron remover 6 is specifically installed on the first belt conveyor 5. The second belt conveyor 8 is located between the first crusher 7 and the primary screening machine 9, and is used to convey the broken glass after being crushed by the first crusher 7 to the primary screening machine 9. The third belt conveyor 11 is located between the second crusher 10 and the secondary screening machine 12, and is used to convey the product after being crushed by the second crusher 10 to the secondary screening machine 12. One end of the fourth belt conveyor 13 is located below the outlet end of the undersize product of the secondary screening machine 12, and is used to convey the glass powder screened out by the secondary screening machine 12 toward the location of the diversion valve 19. The second iron remover is located at the other end of the fourth belt conveyor 13, that is, at the end of the fourth belt conveyor 13.

[0030] in, Figure 1 The positional relationship of the first crusher 7, the second crusher 10, the primary screening machine 9, the secondary screening machine 12, the first belt conveyor 5, the second belt conveyor 8, the third belt conveyor 11, and the fourth belt conveyor 13 is only a schematic diagram of their front-to-back positions in the direction of glass crushing and is not limited to their height positional relationship in this utility model.

[0031] This utility model also includes a powder channel 17, which is located below the side of the fourth belt conveyor 13 with the second iron separator. The powder channel 17 is used to allow glass powder removed by the second iron separator to fall onto the fourth belt conveyor 13. The end of the powder channel 17 is positioned towards or connected to the inlet end of the diversion valve 19, preferably connected to the inlet end of the diversion valve 19, to reduce the dispersion of glass powder. (Reference) Figure 1 As shown, when the glass powder is conveyed to the end of the fourth belt conveyor 13, iron impurities such as iron filings are adsorbed by the action of the second iron remover, and the glass powder falls down along the end of the fourth belt conveyor 13 and flows along the powder channel 17 to the diversion valve 19.

[0032] This utility model also includes an impurity channel 18 and an impurity collection box 25. The roller at the other end of the fourth belt conveyor 13 is a magnetic roller 14, which forms the second iron remover. The impurity channel 18 is located below the end of the fourth belt conveyor 13 with the second iron remover, and is used for iron impurities adsorbed by the second iron remover on the fourth belt conveyor 13 to fall into. The end of the impurity channel 18 is oriented towards or connected to the impurity collection box 25, and is used to collect iron filings and other iron impurities falling along the impurity channel 18. Specifically, refer to... Figure 1As shown, under the action of the magnetic roller 14, when the glass powder falls along the powder channel 17, iron filings and other iron impurities are still adsorbed on the surface of the belt of the fourth belt conveyor 13. As the belt moves, these impurities move below the fourth belt conveyor 13. With the continuous movement of the belt, the iron filings and other iron impurities gradually move away from the magnetic roller 14, and the attraction decreases, thus falling into the impurity channel 18 under gravity, or further... Figure 1 A scraper is vertically installed on the left side of the impurity channel 18 from the perspective of the viewpoint, which further scrapes off iron impurities such as iron filings on the belt.

[0033] like Figure 1 As shown, preferably, the other end of the first conveying unit 15 of this invention is positioned between the second crusher 10 and the secondary screening machine 12, that is, towards the third belt conveyor 11. The broken glass discharged from the product outlet of the primary screening machine 9 is screened twice by the secondary screening machine 12 and then conveyed between the feeding device and the first crusher 7 via the second conveying unit 16. Specifically, the other end of the second conveying unit 16 is positioned on the first belt conveyor 5 in the area between the feeding device and the first iron remover 6. This means that the broken glass requiring further crushing first passes through the first iron remover 6 to remove iron before being fed into the first crusher 7 for further crushing, reducing wear on the internal components of the first crusher 7. Preferably, both the first conveying unit 15 and the second conveying unit 16 are chutes, resulting in a simple structure. In other embodiments, the first conveying unit 15 and the second conveying unit 16 can also be other conveying mechanisms.

[0034] like Figure 1 As shown, the feeding device includes a tilting mechanism 2, a buffer bin 3, and a vibrating feeder 4. The tilting mechanism 2 drives the material box 1 containing broken glass to tilt, so as to pour the broken glass into the buffer bin 3. The outlet end of the buffer bin 3 faces the inlet end of the vibrating feeder 4. Specifically, the tilting mechanism 2 is provided with a clamping structure for clamping and fixing the material box 1. After the material box 1 is placed on the tilting mechanism 2 and fixed, the tilting mechanism 2 tilts the material box 1, pouring out the broken glass. The vibrating feeder 4 then evenly conveys the broken glass in the buffer bin 3 to the first belt conveyor 5. In other configurations, the feeding device can also be other devices that meet the requirement of uniform feeding.
