Description

Technical Field

[0001] This invention relates to the field of vertical mill technology, and more specifically to a vertical mill material spreader. Background Technology

[0002] Vertical roller mills are grinding equipment that integrates fine crushing, drying, grinding, powder selection, and conveying. They are widely used in solid material grinding and ultrafine grinding in various fields such as cement, building materials, power, metallurgy, chemical industry, and non-metallic mining. The grinding process of a vertical roller mill is mainly accomplished through a combination of grinding rollers and grinding discs. The material is ground into powder between the grinding rollers and the grinding discs. The rotation of the grinding discs drives the grinding rollers accordingly, ensuring that the material is fully ground.

[0003] However, in the existing technology, the discharge center pipe of the vertical mill is often directly below the mill, that is, the material falls directly onto the grinding disc, and then the rotation of the grinding disc spreads the material onto the grinding rollers for grinding. This results in uneven distribution of material onto the grinding disc, making it impossible to evenly spread the incoming material, thus leading to poor grinding efficiency and grinding effect of the grinding rollers. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical mill material spreader, which can uniformly compact and spread the incoming material, and simultaneously turn over and compact the ground material, greatly improving the crushing efficiency and effect. In addition, by adjusting the first and second material spreading mechanisms, the material spreading mechanism can be adapted to the vertical mill for grinding materials of different fineness, thus improving the applicability of the material spreading mechanism.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A vertical mill material spreading machine includes a mounting base, a vertical mill box fixedly connected to the top of the mounting base, a mounting plate fixedly connected inside the vertical mill box, a threaded rod rotatably connected to the top of the mounting plate, a first transmission mechanism connected to the mounting plate being driven to the top of the threaded rod, a threaded sleeve threadedly fitted to the outer surface of the threaded rod, a mounting block rotatably connected to the bottom of the threaded sleeve, a guide rod slidably connected to the top of the mounting block being fixedly connected to the top of the mounting block, a first spreading mechanism being provided on both sides of the mounting block, a second spreading mechanism being fixedly connected to the bottom of the mounting block, and a grinding mechanism being provided inside the vertical mill box.

[0007] As a further aspect of the present invention: the first material laying mechanism includes a connecting plate that is fixedly connected to the mounting block, and an arc-shaped wear-resistant plate is fixedly connected to the outer surface of the connecting rod.

[0008] As a further aspect of the present invention: the second material spreading mechanism includes a mounting box fixedly connected to the mounting block, two drive shafts are rotatably connected inside the mounting box, one end of the drive shaft is drivenly connected to a second transmission mechanism, one end of one of the drive shafts is fixedly connected to a mounting shaft, a plurality of stirring rods are fixedly connected to the outer surface of the mounting shaft, one end of the other mounting shaft is fixedly connected to a distributing roller, a plurality of rubber hoses are fixedly connected to the outer surface of the distributing roller, and one end of the rubber hoses is fixedly connected to a striking head.

[0009] As a further aspect of the present invention: the second transmission mechanism includes a first motor fixedly connected to the mounting box, the output end of the first motor being fixedly connected to a first rotating shaft via a coupling, a first bevel gear being fixedly sleeved on the outer surface of the first rotating shaft, and a second bevel gear being fixedly sleeved on the outer surface of the first bevel gear and meshing with the transmission shaft.

[0010] As a further aspect of the present invention: the first transmission mechanism includes a transmission box fixedly connected to the mounting plate, a second motor fixedly connected inside the transmission box, a second rotating shaft fixedly connected to the output end of the second motor via a coupling, a third gear fixedly sleeved on the outer surface of the second rotating shaft, and a fourth gear fixedly sleeved on the outer surface of the third gear.

[0011] As a further aspect of the present invention: the outer surface of the threaded sleeve is rotatably connected to an installation ring, and the top of the installation ring is fixedly connected to a dustproof soft sleeve that is fixedly connected to the installation plate.

[0012] As a further aspect of the present invention: the grinding mechanism includes a grinding disc rotatably connected to a vertical grinding box, two grinding rollers connected to the vertical grinding box are arranged above the grinding disc, and a retaining ring is fixedly connected inside the vertical grinding box.

[0013] As a further aspect of the present invention: connecting blocks are fixedly connected to both sides of the mounting plate, and connecting bolts are fixedly connected to the connecting blocks.

[0014] The beneficial effects of this invention are:

[0015] (1) The material is turned over by the second material spreading mechanism so that it is evenly fed into the arc wear-resistant plate on the first material spreading mechanism for compaction and flattening. This prevents the material from being piled up and stuck in the arc wear-resistant plate. The flattening and compaction of the arc wear-resistant plate facilitates the subsequent grinding rollers to grind the material. At the same time, the material spreading roller on the second material spreading mechanism drives the rubber hose and the striking ball to rotate and turn over the ground material. Then, the arc wear-resistant plate is used to compact and flatten the material for grinding, so that the material is fully and evenly ground quickly, thereby greatly improving the grinding efficiency and grinding effect of the vertical mill.

[0016] (2) The first transmission mechanism drives the threaded rod to rotate in both directions, and the threaded rod drives the threaded sleeve to move up and down. The threaded sleeve drives the mounting plate to move up and down through the cooperation of the guide rod. The mounting plate drives the first and second material spreading mechanisms to move up and down, thereby adjusting the first and second material spreading mechanisms so that the height of the grinding roller can be adjusted according to the requirements of different grinding fineness. This makes the material spreading mechanism suitable for the grinding mechanism to spread materials when grinding particles of different fineness, thus improving the applicability of the material spreading mechanism.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figures 1-6 As shown, this invention is a vertical mill material spreading machine, including a mounting base 1. A vertical mill box 2 is fixedly connected to the top of the mounting base 1. A mounting plate 3 is fixedly connected inside the vertical mill box 2. A threaded rod 4 is rotatably connected to the top of the mounting plate 3. A first transmission mechanism connected to the mounting plate 3 is driven to the top of the threaded rod 4. A threaded sleeve 5 is threadedly fitted to the outer surface of the threaded rod 4. A mounting block 6 is rotatably connected to the bottom of the threaded sleeve 5. A guide rod 7, which is slidably connected to the mounting plate 3, is fixedly connected to the top of the mounting block 6. First spreading mechanisms are provided on both sides of the mounting block 6. A second spreading mechanism is fixedly connected to the bottom of the mounting block 6. A grinding mechanism is provided inside the vertical mill box 2. The threaded rod 4 is driven to rotate forward and backward through the first transmission mechanism. The threaded rod 4 drives the threaded sleeve 5 to move up and down. The threaded sleeve 5, in conjunction with the guide rod 7, drives the mounting plate 3 to move up and down. The mounting plate 3 drives the first and second material spreading mechanisms to move up and down, thereby adjusting the first and second material spreading mechanisms. This allows the first and second material spreading mechanisms to adjust the height of the grinding roller 62 according to different grinding fineness requirements, making the material spreading mechanism suitable for spreading materials when grinding particles of different fineness. This improves the applicability of the material spreading mechanism. At the same time, through the cooperation of the first and second material spreading mechanisms, the incoming material and the ground material are quickly compacted and leveled, and the ground material is turned over, thereby greatly improving the grinding efficiency and grinding effect of the vertical mill.

[0028] Example 2

[0029] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first material spreading mechanism includes a connecting plate 11 fixed to the mounting block 6. An arc-shaped wear-resistant plate 12 is fixedly connected to the outer surface of the connecting plate 11. When the material enters the vertical mill box 2, the grinding disc 61 drives the material to rotate. When the material enters the arc-shaped wear-resistant plate 12, it first enters the bottom of the arc-shaped wear-resistant plate 12, and is then flattened and compacted by the arc-shaped wear-resistant plate 12. Then it is ground and crushed by the grinding roller 62.

[0030] The second material spreading mechanism includes a mounting box 21 fixedly connected to the mounting block 6. Two drive shafts 22 are rotatably connected inside the mounting box 21. One end of each drive shaft 22 is connected to a second transmission mechanism. One end of one drive shaft 22 is fixedly connected to a mounting shaft 23. Multiple stirring rods 24 are fixedly connected to the outer surface of the mounting shaft 23. One end of the other mounting shaft 23 is fixedly connected to a distributing roller 25. Multiple rubber hoses 26 are fixedly connected to the outer surface of the distributing roller 25. One end of each rubber hose 26 is fixedly connected to a striking head 27. The second transmission mechanism drives the two drive shafts 22 to rotate. One drive shaft 22 drives the mounting shaft 23 to rotate, which in turn drives the stirring rods 24 to rotate. The stirring rods 24 agitate and flatten the incoming material, allowing it to smoothly enter the bottom of the arc-shaped wear-resistant plate 12, preventing excessive material accumulation and soiling of the arc-shaped wear-resistant plate 12. To mitigate the risk of raw material briquettes, the powder ground by the grinding roller 62 is tumbled again to ensure thorough re-grinding. It is then compacted and leveled by the arc-shaped wear-resistant plate 12, followed by grinding by the grinding roller 62. After grinding, the material passes under the distribution roller 25. At this point, the second transmission mechanism drives the transmission shaft 22 and the distribution roller 25 to rotate. The distribution roller 25 drives the rubber hose 26 to rotate, which in turn drives the striking head 27 to strike and tumble the freshly ground material. This causes the unground material at the bottom to rise, and the material is then compacted and leveled again by the arc-shaped wear-resistant plate 12. It is then ground again by the grinding roller 62, ensuring that each batch of material entering the bottom of the grinding roller 62 is leveled and ground at the same height. Simultaneously, the ground material is tumbled to ensure thorough grinding of the unground material, thus greatly improving the grinding efficiency and effect of the internal machine on slag.

[0031] The second transmission mechanism includes a first motor 31 fixedly connected to the mounting box 21. The output end of the first motor 31 is fixedly connected to a first rotating shaft 32 via a coupling. A first bevel gear 33 is fixedly sleeved on the outer surface of the first rotating shaft 32. A second bevel gear 34 is meshed with the outer surface of the first bevel gear 33 and fixedly sleeved on the transmission shaft 22. The first motor 31 drives the first rotating shaft 32 to rotate, and the first rotating shaft 32 drives the transmission shaft 22 to rotate via the first bevel gear 33 and the second bevel gear 34.

[0032] The first transmission mechanism includes a transmission box 41 fixedly connected to the mounting plate 3. A second motor 42 is fixedly connected inside the transmission box 41. The output end of the second motor 42 is fixedly connected to a second rotating shaft 43 via a coupling. A third gear 44 is fixedly sleeved on the outer surface of the second rotating shaft 43. A fourth gear 45 is meshed with the outer surface of the third gear 44 and fixedly sleeved on the threaded rod 4. The second motor 42 is controlled by a PLC programming program, which can control the second motor 42 to rotate in both directions and at different angles. The second motor 42 drives the second rotating shaft 43 to rotate, and the second rotating shaft 43 drives the threaded rod 4 to rotate via the third gear 44 and the fourth gear 45.

[0033] The outer surface of the threaded sleeve 5 is rotatably connected to an installation ring 51. The top of the installation ring 51 is fixedly connected to a dustproof soft sleeve 52 that is fixedly connected to the installation plate 3. The dustproof soft sleeve 52 protects the threaded rod 4 from dust, preventing dust from entering the threaded rod 4 and causing the threaded rod 4 to be unable to drive the threaded sleeve 5 to move.

[0034] The grinding mechanism includes a grinding disc 61 rotatably connected to the vertical mill box 2. Two grinding rollers 62 connected to the vertical mill box 2 are arranged above the grinding disc 61. A retaining ring 63 is fixedly connected inside the vertical mill box 2. The slag is ground by the cooperation of the grinding rollers 62 and the grinding disc 61, and the material is blocked by the retaining ring 63.

[0035] Both sides of the mounting plate 3 are fixedly connected to connecting blocks 71, and connecting bolts are fixedly connected to the connecting blocks 71. The mounting plate 3 can be installed through the connecting blocks 71.

[0036] The working principle of this invention is as follows: The material to be ground is poured into the vertical mill box 2 through the feed pipe. Then, the second transmission mechanism drives two transmission shafts 22 to rotate. One of the transmission shafts 22 drives the mounting shaft 23 to rotate, and the mounting shaft 23 drives the stirring rod 24 to rotate. The stirring rod 24 turns and flattens the incoming material, allowing it to smoothly enter the bottom of the arc-shaped wear-resistant plate 12. This prevents excessive material from accumulating and causing the risk of material jamming on the arc-shaped wear-resistant plate 12. At the same time, the powder ground by the grinding roller 62 is also turned over again to ensure that it is fully ground again. Then, it is compacted and flattened by the arc-shaped wear-resistant plate 12, and then ground by the grinding roller 62. After grinding, the powder is distributed. Below roller 25, the second transmission mechanism drives the transmission shaft 22 and the distribution roller 25 to rotate. The distribution roller 25 drives the rubber hose 26 to rotate, and the rubber hose 26 drives the striking head 27 to strike and turn the material after grinding, so that the unground material at the bottom of the material is turned upward. Then, it is compacted and flattened again by the arc wear-resistant plate 12, and then ground again by the grinding roller 62. This ensures that the material entering the bottom of the grinding roller 62 is flattened at the same height for grinding each time. At the same time, the ground material is turned over so that the unground material is fully ground, thereby greatly improving the grinding efficiency and grinding effect of the inner machine on the slag.

[0037] The first transmission mechanism drives the threaded rod 4 to rotate in both directions, which in turn drives the threaded sleeve 5 to move up and down. The threaded sleeve 5, in conjunction with the guide rod 7, drives the mounting plate 3 to move up and down. The mounting plate 3 then drives the first and second material spreading mechanisms to move up and down, thereby adjusting the first and second material spreading mechanisms. This allows the first and second material spreading mechanisms to adjust the height of the grinding roller 62 according to the requirements of different grinding fineness, making the material spreading mechanism suitable for spreading materials when the grinding mechanism grinds particles of different fineness, thus improving the applicability of the material spreading mechanism.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
