Description

Technical Field

[0001] The present invention relates to the technical field of glass crushing, and particularly to a glass crushing device facilitating impurity removal. Background Art

[0002] In many fields such as glass product production, building decoration, and daily waste treatment, a large amount of glass waste is generated every day. If these glass wastes cannot be recycled reasonably and effectively, it will not only cause huge waste of resources, but also have a serious negative impact on the environment, such as occupying a large amount of land resources, polluting soil and water sources, etc. Therefore, recycling and reprocessing glass waste has become an important link in realizing resource recycling and promoting sustainable development.

[0003] In the process of recycling and treating glass waste, crushing is one of the key preliminary processes. Its purpose is to convert glass waste with large volume and various shapes into glass fragments with smaller particles and relatively uniform sizes, so as to facilitate more efficient melting, reprocessing and other operations in the follow-up. However, the existing glass crushing devices have many limitations in practical applications and are difficult to meet the increasing demand for glass waste recycling and treatment; the sources of glass waste are extensive and the forms are diverse, covering products with different shapes such as flat glass, curved glass, and special-shaped glass. Most of the traditional glass crushing devices are designed relatively simply, lacking adaptability to different-shaped glass wastes, and various impurities are often mixed in the glass waste, especially iron impurities. These iron impurities may come from metal fittings in the glass product production process, iron nails or metal frames remaining during building decoration, etc. If these iron impurities are not effectively removed during the crushing process, they will enter the subsequent processing links together with the glass fragments, not only affecting the efficiency of the subsequent processing process, but also possibly causing instability in the quality of related products. To solve the above problems, we have proposed a glass crushing device facilitating impurity removal. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a glass crushing device that is convenient for removing impurities, and has the following beneficial effects:

[0017] 1. The glass crushing device facilitating impurity removal is equipped with a feeding plate with a long magnet plate on the conveyor belt. During the transportation of the preliminarily crushed glass blocks, by utilizing the adsorption property of the magnet, it actively captures the iron impurities mixed in the glass waste, achieving efficient separation of impurities from the glass. Meanwhile, in cooperation with a unique impurity removal device, the scraper can completely scrape off and collect the impurities adsorbed on the long magnet plate, preventing the impurities from mixing back into the glass fragments. This dual-guarantee impurity removal method significantly reduces the impurity content in the recycled glass, remarkably enhancing the purity and quality of the recycled glass.

[0018] 2. The glass crushing device facilitating impurity removal adopts a hierarchical crushing design. First, the first crushing device conducts preliminary crushing on the glass waste. By utilizing the relative movement between the cutting wheel and the installation arc plate, the large glass waste is cut into relatively smaller blocks, preparing for subsequent processing. The preliminarily crushed glass blocks are transported by the conveyor belt to the second crushing device, where they undergo secondary fine crushing under the high-speed rotation of the crushing rollers, further breaking the glass blocks into more uniform small particles. This hierarchical crushing method not only ensures the crushing effect, making the size of the glass fragments meet the requirements of subsequent processing, but also avoids unnecessary over-crushing, improving the crushing efficiency, reducing energy consumption, and achieving high efficiency and energy conservation in the crushing process.

[0019] 3. The glass crushing device facilitating impurity removal is provided with a multi-stage screening structure. The screen holes of the three screen boxes gradually decrease from top to bottom. The eccentric wheel is driven by the third driving motor to rotate, generating vibration, which makes the screen boxes vibrate regularly. During the vibration process, glass fragments of different particle sizes will pass through the screen meshes of the corresponding screen holes according to their own sizes, achieving precise separation and improving the utilization rate and added value of the glass fragments.

[0020] 4. The structural design and power transmission system of the glass crushing device facilitating impurity removal achieve a high degree of automation in each link. Starting from the glass waste entering the feed hopper, it successively undergoes preliminary crushing, iron impurity removal, secondary crushing, and screening. The connections between the links are tight, without much manual intervention, greatly reducing the labor intensity and improving the production efficiency and market competitiveness of the enterprise.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-8 , a glass crushing device convenient for removing impurities, including a first support frame 1, a conveyor belt support frame 2 and a screening support frame 4, which are arranged adjacent to each other. A conveyor belt 3 is arranged on the conveyor belt support frame 2. One end of the first support frame 1 is fixedly connected to a first crushing device 5, and the other end of the first support frame 1 is fixedly connected to a first driving motor 6. A pulley 1 is fixedly connected to the rotating shaft of the first driving motor 6. A second crushing device 9 is arranged on the top of the screening support frame 4. An impurity removal device 10 is arranged at one end of the conveyor belt support frame 2. A feed hopper 8 is arranged at the upper end of the second crushing device 9, and the feed hopper 8 is in contact with the conveyor belt 3 on one side;

[0032] It further includes a screening device which is arranged on the screening support 4 and is used for screening the broken glass fragments.

[0033] Furthermore, the first crushing device 5 includes a first crushing housing 11, a rotating roller 12, a second pulley 13, a mounting arc plate 14 and a cutting wheel 15. A first crushing housing 11 is fixedly connected to the first support frame 1. A rotating roller 12 is rotatably connected to the first crushing housing 11. One end of the rotating roller 12 is fixedly connected to a second pulley 13. The second pulley 13 is tensioned and connected to the first pulley 7 through a belt. A plurality of equally spaced mounting arc plates 14 are fixedly connected to the inner wall of one side of the first crushing housing 11. A plurality of cutting wheels 15 are fixedly connected to the side surface of the rotating roller 12 corresponding to the inner cavity of the first crushing housing 11. The plurality of cutting wheels 15 are all movably clamped in the mounting arc plates 14. The first support frame 1 provides fixed support for the first crushing housing 11, enabling the entire first crushing device 5 to operate stably. The rotating roller 12 is rotatably connected to the first crushing housing 11, and the second pulley 13 is fixed at one end of the rotating roller 12 and is tensioned and connected to the first pulley 7 at the rotating shaft of the first driving motor 6 through a belt. In this way, the power of the first driving motor 6 can be transmitted to the rotating roller 12 to drive its rotation. The plurality of equally spaced mounting arc plates 14 on the inner wall of one side of the first crushing housing 11 provide a stable working track for the cutting wheels 15. The plurality of cutting wheels 15 fixedly connected to the side surface of the rotating roller 12 corresponding to the inner cavity of the first crushing housing 11 are movably clamped in the mounting arc plates 14. When the rotating roller 12 rotates, the cutting wheels 15 cooperate with the mounting arc plates 14. Through the rotation of the cutting wheels 15 and the relative movement with the mounting arc plates 14, the glass waste products entering the first crushing housing 11 are cut and crushed, cutting the large glass waste products into relatively small blocks, realizing the function of preliminary crushing, and preparing for the subsequent crushing and processing links.

[0034] Further, one upper end side of the first crushing housing 11 is open and fixedly connected with a feeding inclined plate 18. The bottom of the first crushing housing 11 has an open structure, and the bottom of the first crushing housing 11 is fixedly connected with a discharge arc plate 19. One end of the discharge arc plate 19 away from the first crushing housing 11 extends above one end of the conveyor belt 3. One upper end side of the first crushing housing 11 is open and fixedly connected with the feeding inclined plate 18. This design enables the glass waste to conveniently and smoothly enter the interior of the first crushing housing 11, providing good feeding conditions for the preliminary crushing of the glass waste. The bottom of the first crushing housing 11 has an open structure and is fixedly connected with the discharge arc plate 19. One end of the discharge arc plate 19 away from the first crushing housing 11 extends above one end of the conveyor belt 3. The preliminarily crushed glass blocks can slide down through the bottom opening onto the discharge arc plate 19 and then slide onto the conveyor belt 3 along the discharge arc plate 19, realizing the linkage between the preliminary crushing device and the material conveying device, ensuring that the crushed glass can timely and smoothly enter the next processing link, and improving the working efficiency and smoothness of the entire device.

[0035] Further, the first crushing device 5 further includes a feeding and crushing rotating rod 16 and a third pulley 17. One end of the feeding and crushing rotating rod 16 is rotatably connected to the inner walls on both sides of the first crushing housing 11 near one end of the feeding inclined plate 18. One end of the feeding and crushing rotating rod 16 extends to the outer side of the first crushing housing 11 and is fixedly connected with the third pulley 17. The third pulley 17 is tensionedly connected to the other end of the second pulley 13 through a belt. During the rotation of the feeding and crushing rotating rod 16, on the one hand, it can play an auxiliary conveying role for the glass waste entering the first crushing housing 11, enabling the glass waste to enter the crushing area more smoothly; on the other hand, the feeding and crushing rotating rod 16 itself also has a certain crushing function, capable of preliminarily squeezing and crushing the glass waste, cooperating with the crushing functions of the rotating roller 12 and the cutting wheel 15, and improving the effect and efficiency of the preliminary crushing.

[0036] Further, a plurality of equally spaced feeding plates 20 are fixedly connected to the conveyor belt 3. The feeding plates 20 are L-shaped. Magnet long plates are fixedly connected to one side of the plurality of feeding plates 20 perpendicular to the conveyor belt support 2. The L-shaped design of the feeding plates 20 can play a good role in blocking and guiding when conveying the glass blocks, preventing the glass blocks from sliding off the conveyor belt 3 during transportation. Magnet long plates are fixedly connected to one side of the plurality of feeding plates 20 perpendicular to the conveyor belt support 2. When the conveyor belt 3 drives the feeding plates 20 and the glass blocks to move, the iron impurities mixed in the glass waste will be adsorbed by the magnet long plates.

[0037] Further, the impurity removal device 10 includes an iron impurity collection box 21, a mounting plate 22, a first connecting rod 23, and a scraping plate 24. The iron impurity collection box 21 is movably clamped on the conveyor belt support 2. Mounting plates 22 are fixedly connected to both sides of the conveyor belt support 2 corresponding to the two ends of the iron impurity collection box 21. The components on the two mounting plates 22 are symmetrically distributed. A first connecting rod 23 is rotatably connected between the two mounting plates 22, and a scraping plate 24 is fixedly connected to the first connecting rod 23. The iron impurity collection box 21 is movably clamped on the conveyor belt support 2 for collecting the scraped iron impurities. Mounting plates 22 are fixedly connected to both sides of the conveyor belt support 2 corresponding to the two ends of the iron impurity collection box 21.

A first connecting rod 23 is rotatably connected between the two mounting plates 22, and a scraping plate 24 is fixedly connected to the first connecting rod 23. When the magnet long plate on the conveyor belt 3 moves the iron impurities to the scraping plate 24, the scraping plate 24 can scrape off the iron impurities on the magnet long plate and make them fall into the iron impurity collection box 21, realizing the removal and collection of iron impurities.

[0038] Further, a connecting bolt 26 is fixedly connected to the lower end of the side of the mounting plate 22 away from the iron impurity collection box 21. Oblique blocks 25 are fixedly connected to both ends of the first connecting rod 23 corresponding to the outer ends of the two mounting plates 22. A second connecting rod 27 is fixedly connected to one side of the connecting bolt 26. The second connecting rod 27 is movably inserted into one end of the oblique block 25 and extends to the other side of the oblique block 25 to be fixedly connected with a limiting plate. A return spring 28 is movably sleeved on the side of the second connecting rod 27 between the limiting plate and the side of the oblique block 25. The structural design enables the return spring 28 to always exert a pressure on the scraping plate 24 in the direction of the magnet long plate when the scraping plate 24 scrapes off iron impurities, making the scraping plate 24 always keep close contact with the magnet long plate to ensure that the impurities can be completely scraped off. At the same time, when the scraping plate 24 is under a certain pressure during the scraping process, the return spring 28 can undergo elastic deformation to make the scraping plate 24 swing appropriately, avoiding excessive wear on the conveyor belt 3, which not only ensures the effect of impurity scraping but also extends the service life of the conveyor belt 3.

[0039] Further, the second crushing device 9 includes a second driving motor 29, a gear reversing box 30, and a second crushing device 31. A second driving motor 29 is fixedly connected to one end of the top of the screening support 4, and a second crushing device 31 is fixedly connected to the other end of the top of the screening support 4. A feed hopper 8 is fixedly connected to the top of the second crushing device 31. A crushing roller is rotatably connected in the inner cavity of the gear reversing box 30. A gear reversing box 30 is drivingly connected between the second driving motor 29 and the second crushing device 31, and the gear reversing box 30 is fixed on the top of the screening support 4.

[0040] Furthermore, the second crushing device 9 further includes a screening base 32, vibration springs 35, a circular connecting plate 36, a third driving motor 37, and a baffle cover 38. The bottom of the screening support 4 is fixedly connected to the screening base 32. An annular plate is fixed to the upper end of the screening base 32. A plurality of vibration springs 35 evenly distributed at equal intervals in a ring shape are fixedly connected to the upper side of the annular plate. The tops of the plurality of vibration springs 35 are fixedly connected to the circular connecting plate 36. The bottom surface of the circular connecting plate 36 is fixedly connected to the third driving motor 37. One side of the third driving motor 37 is fixedly connected to the baffle cover 38. An eccentric wheel is arranged inside the baffle cover 38 and is fixedly connected to the rotating shaft of the third driving motor 37.

[0041] Furthermore, connecting plates 33 are fixedly connected to both ends of the upper side surface of the circular connecting plate 36. Three screening boxes 34 are fixedly connected between the two connecting plates 33. A discharge pipe 40 is fixedly connected to one side of each screening box 34. Screening meshes are fixedly connected to the bottom inner walls of the three screening boxes 34. The screening mesh apertures of the three screening boxes 34 are different. A top cover 39 is fixedly connected to the top of the screening box 34. The top of the top cover 39 is fixedly connected to the lower end of the second crushing device 31 and the inner cavities are connected and communicated.

[0042] Working principle: After the waste glass enters the device from the feed hopper, it successively undergoes processes such as primary crushing, iron impurity removal, secondary crushing, and screening, and finally obtains glass fragments that meet the requirements, while separating out iron impurities. In the primary crushing part, the first driving motor 6 serves as the power source for the primary crushing part, and a pulley one 7 is fixedly connected to its rotating shaft. The waste glass enters the first crushing housing 11 from the feed hopper 8. As the rotating roller 12 rotates, the cutting wheel 15 and the installation arc plate 14 cooperate with each other to cut and crush the waste glass. This design can effectively perform primary crushing on waste glass of different shapes through the relative movement of the cutting wheel and the fixed arc plate, cutting large waste glass into relatively small blocks to prepare for subsequent processing. One side of the upper end of the first crushing housing 11 is open and fixedly connected to a feed inclined plate 18 to facilitate the smooth entry of waste glass into the crushing device. The bottom of the first crushing housing 11 is of an open structure and is fixedly connected to a discharge arc plate 19. The end of the discharge arc plate 19 away from the first crushing housing 11 extends above one end of the conveyor belt 3. The glass blocks after primary crushing slide onto the conveyor belt 3 through the discharge arc plate 19, realizing the linkage between primary crushing and material transportation and ensuring that the crushed glass can enter the next processing link in a timely manner.

[0043] The conveyor belt 3 is supported by the conveyor belt support frame 2. A plurality of equally spaced feeding plates 20 are fixedly connected to the conveyor belt 3. The feeding plates 20 are L-shaped, and magnet long plates are fixedly connected to one side of the plurality of feeding plates 20 perpendicular to the conveyor belt support frame 2. When the preliminarily crushed glass blocks move along with the conveyor belt 3, the iron impurities mixed in the glass waste will be adsorbed by the magnet long plates. Through the adsorption of the magnet long plates, the iron impurities in the glass waste can be effectively removed, preventing the iron impurities from entering the subsequent processing links, affecting the quality of the recycled glass products, reducing the wear of the processing equipment, and improving the service life of the equipment. When the magnet long plates on the conveyor belt 3 carry the iron impurities and move to the scraper 24, the scraper 24 scrapes off the iron impurities on the magnet long plates, causing them to fall into the iron impurity collection box 21. The reset spring 28 functions to keep the scraper 24 in close contact with the magnet long plates at all times, ensuring that the impurities can be completely scraped off, and at the same time ensuring that the scraper can swing appropriately when subjected to a certain pressure, avoiding excessive wear on the conveyor belt.

[0044] When the glass blocks enter the feed hopper 8 of the second crushing housing 31 from the conveyor belt 3, the second drive motor 29 is started, and the crushing roller is driven to rotate through the gear reversing box 30. The glass blocks entering the second crushing housing 31 are subjected to secondary fine crushing under the action of the crushing roller. The crushing roller rotates at a high speed, impacts, squeezes, and grinds the glass blocks, further crushing the preliminarily crushed glass blocks into smaller particles. After secondary fine crushing, the size of the glass slag is more uniform, which can meet the strict requirements of the subsequent processing for the particle size of the raw materials, improving the quality and production efficiency of the recycled glass products.

[0045] The screening device is arranged on the screening support 4 and is used to screen the crushed glass fragments. When the third drive motor 37 is started, the eccentric wheel rotates at a high speed. Since the center of gravity of the eccentric wheel is not on the rotation axis, a centrifugal force will be generated, causing the circular connecting plate 36 to vibrate. The vibration spring 35 plays a role in supporting and buffering, transmitting the vibration generated by the third drive motor 37 to the screening box 34, and at the same time enabling the screening box to vibrate regularly. The inner walls of the bottom sides of the three screening boxes 34 are fixedly connected with screening meshes, and the screening mesh holes of the three screening boxes 34 are of different sizes, gradually decreasing from top to bottom. Through this multi-stage screening method, the glass slag can be accurately separated according to different particle sizes, meeting different production requirements, and greatly improving the utilization rate of the glass slag.
