Description

Technical Field

[0001] This utility model belongs to the field of phosphate mining technology, and specifically relates to an ore crushing and shaking screening device for mining medium-thick phosphate deposits. Background Technology

[0002] Crushing is a necessary step in the phosphate mining process. Through preliminary crushing, large pieces of phosphate ore can be broken into smaller particles, making them easier to process later.

[0003] Currently, Chinese utility model patent CN219519524U discloses an ore crushing and screening device. Existing crushing devices, when using motor-driven rollers to crush phosphate ore, suffer from poor crushing efficiency due to the unidirectional rotation of the rollers. Often, multiple crushing operations are required over a long period to grind the phosphate ore into suitable particles, resulting in low processing efficiency. Furthermore, phosphate ore easily gets stuck on the roller surface, hindering effective crushing. After crushing, the phosphate ore needs to be screened to remove larger, substandard particles for further crushing. However, in existing screening methods, the phosphate ore accumulates on top of the screen due to the fixed outlet, making it difficult to spread the ore evenly for screening. This results in low screening efficiency and a tendency for screen blockage. Utility Model Content

[0004] The purpose of this invention is to provide an ore crushing and shaking screening device for mining medium-thick phosphate deposits. Its advantages are that it improves the efficiency of phosphate ore crushing and screening, and prevents phosphate ore from clogging the screen.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a crushing and shaking screening device for mining medium-thick phosphate deposits, comprising a crushing tank, a feeding port fixedly connected to the top of the crushing tank, a first motor bolted to one side of the outside of the crushing tank, a first roller cylinder bolted to the output end of the first motor, a first turntable fixedly sleeved on the surface of the first roller cylinder near the first motor, and a second roller cylinder rotatably connected to the first turntable is provided above and below the first roller cylinder; a first gear is bolted to the side of the inner cavity of the crushing tank away from the first turntable, and a second gear meshing with the first gear is bolted to the side of the second roller cylinder away from the first turntable.

[0006] By employing the above technical solution, the second roller is oscillating outside the first roller, thereby compressing and crushing the phosphate ore. Simultaneously, the second roller can mesh with the first gear and the second gear, causing the second roller to rotate in the opposite direction to the first roller as it rotates with the first turntable, thus performing secondary grinding of the phosphate ore and improving the phosphate ore crushing efficiency.

[0007] The present invention is further configured such that: a discharge trough is opened at the bottom of the inner cavity of the crushing tank, and sliding blocks that slide in cooperation with the body of the crushing tank are provided on both opposite sides of the discharge trough; a mesh plate that cooperates with the discharge trough is bolted between the two sliding blocks; a fixing ring that slides in cooperation with the crushing tank is also fixedly sleeved on the surface of the first turntable, the extension end of the fixing ring is inserted into the body of the crushing tank, and a wave groove that slides in cooperation with the sliding block is also opened on the end face of the extension end of the fixing ring; a spring that is bolted to the body of the crushing tank is provided at the end of the mesh plate away from the fixing ring.

[0008] The above technical solution facilitates the discharge of crushed and qualified phosphate ore, while reducing the risk of blockage inside the mesh.

[0009] The present invention is further configured such that a cover plate is hinged to one side of the top of the feeding port.

[0010] By adopting the above technical solution, the top of the feeding port can be covered when not in use to prevent dust from falling into the interior.

[0011] The present invention is further configured such that: the end of the first roller cylinder away from the first turntable is bolted to a second turntable that is rotatably connected to the second roller cylinder, and the surfaces of the second turntable and the first turntable are in sliding fit with the inner wall of the crushing tank.

[0012] By adopting the above technical solution, the second turntable and the first turntable are supported, thereby supporting the first roller and the second roller; at the same time, the internal space of the crushing tank is separated, so that the second turntable can be separated from the installation space of the first roller, the second roller and the first gear, and the second gear, preventing phosphate ore from falling into the gear surface of the first gear and the second gear.

[0013] The present invention is further configured such that wear-resistant liners are bolted to the surfaces of both the first and second rollers.

[0014] The above technical solution facilitates the replacement of damaged wear-resistant liners and improves the service life of the first and second roller cylinders.

[0015] The present invention is further configured such that an inspection door is bolted to one side of the outside of the crushing hopper.

[0016] The above technical solution facilitates the opening of the crushing tank for maintenance and replacement of internal parts.

[0017] The present invention is further configured such that: a discharge pipe communicating with the discharge trough is bolted to the bottom of the crushing tank, a second motor is bolted to one side outside the discharge pipe, and the output end of the second motor is bolted to an auger rotatably installed inside the discharge pipe.

[0018] By adopting the above technical solution, the second motor is turned on to drive the auger to rotate inside the discharge pipe, which facilitates the rapid discharge of the crushed phosphate ore.

[0019] The present invention is further configured such that: the surfaces of the second turntable and the first turntable are both bonded with sealing rings that slide in cooperation with the inner wall of the crushing tank.

[0020] By adopting the above technical solution, the sealing performance is improved, preventing ore powder from entering the gaps.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The phosphate ore is crushed by the second roller pressing cylinder shaking on the surface of the first roller pressing cylinder. At the same time, the second roller pressing cylinder can generate a rotation in the opposite direction to the first roller pressing cylinder through the meshing of the first gear and the second gear, which performs secondary grinding on the phosphate ore, thereby improving the crushing efficiency of the phosphate ore;

[0023] 2. During the crushing process of phosphate ore, the screen plate moves back and forth continuously inside the discharge trough, allowing it to screen the phosphate ore. This facilitates the discharge of properly crushed phosphate ore, reduces the risk of clogging inside the screen plate, and improves its practicality. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 4 A crushing and screening device for mining medium-thick phosphate deposits includes a crushing tank 1, with a feed inlet 2 fixedly connected to the top of the crushing tank 1. A first motor 3 is bolted to one side of the outside of the crushing tank 1, and a first roller 4 is bolted to the output end of the first motor 3. A first turntable 5 is fixedly sleeved on the surface of the first roller 4 near the first motor 3. Second rollers 6, rotatably connected to the first turntable 5, are provided above and below the first roller 4. A first gear 7 is bolted to the side of the inner cavity of the crushing tank 1 away from the first turntable 5, and a second gear 8, meshing with the first gear 7, is bolted to the side of the second roller 6 away from the first turntable 5. The phosphate ore is crushed by the second roller 6 shaking outside the first roller 4. Meanwhile, the second roller 6 can mesh with the first gear 7 and the second gear 8, so that while the second roller 6 rotates with the first turntable 5, the second roller 6 will rotate in the opposite direction to the first roller 4, thus performing secondary grinding of the phosphate ore and improving the phosphate ore crushing efficiency.

[0032] refer to Figure 1 , Figure 2 A cover plate 20 is hinged to one side of the top of the feeding port 2. The top of the feeding port 2 can be covered when not in use to prevent dust from falling into the interior.

[0033] refer to Figure 2 , Figure 4 The end of the first roller 4 furthest from the first turntable 5 is bolted to a second turntable 17, which is rotatably connected to the second roller 6. The surfaces of both the second turntable 17 and the first turntable 5 slide against the inner wall of the crushing tank 1, supporting both the second turntable 17 and the first turntable 5, thereby supporting the first roller 4 and the second roller 6. Simultaneously, this partitions the internal space of the crushing tank 1, separating the second turntable 17 from the installation space of the first roller 4, the second roller 6, and the first gear 7 and the second gear 8, preventing phosphate ore from falling onto the surfaces of the first gear 7 and the second gear 8.

[0034] refer to Figure 2 Wear-resistant liners 19 are bolted to the surfaces of both the first roller press 4 and the second roller press 6. This facilitates the replacement of damaged wear-resistant liners 19 and improves the service life of the first roller press 4 and the second roller press 6.

[0035] refer to Figure 2 , Figure 4 Both the second turntable 17 and the first turntable 5 have sealing rings 18 bonded to their surfaces, which slide against the inner wall of the crushing tank 1. This improves the sealing performance and prevents ore powder from entering the gaps.

[0036] Brief description of the usage process: Phosphate ore is poured into the crushing tank 1 through the feeding port 2. Then, the first motor 3 is turned on to drive the first roller 4 to rotate and crush the phosphate ore. At the same time, the first motor 3 drives the second roller 6 on one side of the first turntable 5 to rotate on the surface of the first roller 4, so that the first roller 4 and the second roller 6 cooperate to squeeze the phosphate ore. Then, the second roller 6 rotates with the first turntable 5 and the second turntable 17, and through the meshing of the first gear 7 and the second gear 8, the second gear 8 is driven to revolve around the surface of the first gear 7, which in turn drives the second roller 6 to rotate on one side of the first turntable 5. During the squeezing process of the phosphate ore by the first roller 4 and the second roller 6, the phosphate ore can be crushed by rotation.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A crushing and shaking screening device for mining medium-thick phosphate deposits includes a discharge chute 12 at the bottom of the inner cavity of a crushing tank 1. Sliding blocks 10, which slide in conjunction with the tank body of the crushing tank 1, are provided on opposite sides of the discharge chute 12. A mesh plate 11, which works in conjunction with the discharge chute 12, is bolted between the two sliding blocks 10. A fixing ring 9, which slides in conjunction with the crushing tank 1, is also fixedly fitted onto the surface of a first turntable 5. The extended end of the fixing ring 9 is inserted into the tank body of the crushing tank 1, and a wave groove that slides in conjunction with the sliding blocks 10 is provided on the end face of the extended end of the fixing ring 9. A spring 13, bolted to the tank body of the crushing tank 1, is provided at the end of the mesh plate 11 away from the fixing ring 9. During the crushing process of phosphate ore, as the first turntable 5 rotates, the corrugated groove on the fixed ring 9 cooperates with the sliding block 10, causing the screen plate 11 to continuously oscillate back and forth inside the discharge chute 12. This allows the screen plate 11 to screen the phosphate ore, facilitating the discharge of properly crushed phosphate ore, reducing the risk of blockage inside the screen plate 11, and improving its practicality.

[0039] refer to Figure 1 An inspection door 21 is bolted to one side of the outside of the crushing tank 1. This allows for easy access to the crushing tank 1 for maintenance and replacement of internal parts.

[0040] refer to Figure 1 , Figure 2 The bottom of the crushing tank 1 is bolted with a discharge pipe 14 that communicates with the discharge chute 12. A second motor 15 is bolted to one side of the outside of the discharge pipe 14. The output end of the second motor 15 is bolted to an auger 16 that is rotatably installed inside the discharge pipe 14. By turning on the second motor 15, the auger 16 is driven to rotate inside the discharge pipe 14, thereby facilitating the rapid discharge of the crushed phosphate ore.

[0041] Brief description of the operation: As the first motor 3 drives the first turntable 5 to rotate, the fixed ring 9 rotates with the first turntable 5 inside the crushing tank 1. The corrugated grooves on one side of the fixed ring 9 push the screen plate 11 on one side of the sliding block 10 to slide inside the discharge chute 12. When the protrusion in the corrugated groove of the fixed ring 9 corresponds to the sliding block 10, the fixed ring 9 pushes the sliding block 10 and the screen plate 11 towards the side of the spring 13, compressing the spring 13. When the groove in the corrugated groove of the fixed ring 9 corresponds to the sliding block 10, the rebound force of the spring 13 can cause the screen plate 11 to reset. This allows the screen plate 11 to continuously oscillate left and right to screen the ground phosphate ore, allowing sufficiently small particles to be discharged, while larger particles remain inside the crushing tank 1 for further crushing.
