Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of round steel ball feeding technology, and more specifically, to a round steel ball feeding device. Background Technology

[0002] In the beneficiation process of porphyry ore, the crushing and grinding process is usually composed of "three-stage closed-circuit crushing + ball milling". During the grinding operation, the ball mill needs to be replenished with steel balls of various specifications in a timely, quantitative and proportional manner to keep the filling rate and ball diameter ratio of the mill within the required range, thereby ensuring that the ball mill operates efficiently and with low consumption. The existing method of feeding steel balls usually involves conveying the round steel balls via a conveyor belt. When the round steel balls are conveyed and fed on the conveyor belt, it is easy to cause an excessive number of round steel balls to be fed at one time. Firstly, the round steel balls are prone to rolling off the side of the conveyor belt. Secondly, the simple conveyor belt makes it difficult to control the weight and quantity of the round steel balls being fed, which can easily affect the grinding effect of the ball mill on the ore. Utility Model Content

[0017] like Figures 1-4The diagram illustrates a round steel ball feeding device according to an embodiment of this disclosure, comprising: a storage tank 1, a feeding box 2, a moving platform 3, a support 4, and a powerful electromagnet 5. A discharge chute 22 is fixedly connected to one end of the storage tank 1. The feeding box 2 is fixedly connected to one side of the storage tank 1, and a feeding port is provided at the bottom of the feeding box 2. The moving platform 3 is slidably disposed on the same side of the storage tank 1 and the feeding box 2 via a moving mechanism. The moving mechanism drives the moving platform 3 to move back and forth between the storage tank 1 and the feeding box 2. The support 4 is fixedly connected to the top of the moving platform 3. The powerful electromagnet 5 is mounted on one end of the support 4 via a lifting mechanism. The lifting mechanism can drive the powerful electromagnet 5. The steel ball 5 moves vertically, and is connected to the storage trough 1, feeding box 2, moving platform 3, support 4, and powerful electromagnet 5. This system replaces the conveyor belt for feeding the round steel balls, reducing the occurrence of falling balls. Furthermore, the weight and quantity of the fed steel balls can be controlled by the magnetic force of the powerful electromagnet 5, improving the grinding efficiency of the ball mill.

[0018] The moving mechanism includes a support plate 6, a toothed plate 7, a fixed frame 8, and a drive assembly. The support plate 6 is fixedly connected to one side of the storage tank 1 and the unloading box 2. The moving platform 3 is slidably connected to the top of the support plate 6 via a sliding assembly. The toothed plate 7 is fixedly connected to the bottom of the support plate 6. The fixed frame 8 is fixedly connected to the bottom of the moving platform 3. The drive assembly is located at the bottom of the fixed frame 8 and can drive the moving platform 3 to move back and forth on the support plate 6. The sliding assembly includes a slide groove 9 and a slider 10. The slide groove 9 is fixedly connected to the top of the support plate 6, and the slider 10 is fixedly connected to the bottom of the moving platform 3. The slider 10 is slidably connected within the slide groove 9. The components include a gear 11 and a first motor 12. The gear 11 is located at the bottom of the fixed frame 8 and meshes with the toothed plate 7. The first motor 12 is installed at the bottom of the fixed frame 8 and its output end is fixedly connected to the gear 11. When it is necessary to transfer the round steel balls in the storage tank 1 to the unloading box 2, the first motor 12 drives the gear 11 to rotate. Due to the meshing of the gear 11 with the toothed plate 7, the fixed frame 8 and the moving platform 3 are moved. During the movement of the moving platform 3, the bottom end of the moving platform 3 slides in the sliding groove 9, thereby supporting the moving platform 3 to move stably in the storage tank 1 and the unloading box 2.

[0019] The lifting mechanism includes: a fixed block 13, a guide rod 14, a base plate 15, a traction rope 16, a guide assembly, and a drive assembly. The fixed block 13 is fixedly connected to one end of the bracket 4. A sliding hole is provided on the fixed block 13 to support the vertical sliding of the guide rod 14. The guide rod 14 is slidably connected within the sliding hole. The base plate 15 is fixedly connected to the bottom end of the guide rod 14. A powerful electromagnet 5 is installed at the bottom end of the base plate 15. A through-hole is provided on the bracket 4. One end of the traction rope 16 passes through the through-hole and is fixedly connected to the base plate 15. The guide assembly is... The guide assembly is located at the top of the support 4 to guide the traction rope 16 during movement. The drive assembly is located at the top of the moving platform 3 to control the extension and retraction of the traction rope 16. The guide assembly includes: a fixed base 17 and guide wheels 18. Two fixed bases 17 are provided, both fixedly connected to the top of the support 4. Guide wheels 18 are rotatably connected to each of the two fixed bases 17. Guide grooves are formed on the circumferential surfaces of the two guide wheels 18 to limit and guide the traction rope 16. The traction rope 16 is located within the two guide grooves. The drive assembly includes: a stable base 19, a take-up shaft 20, and a second motor 21. The stable base 19 is fixedly connected to the top of the moving platform 3. The take-up shaft 20 is rotatably connected within the stable base 19. The other end of the traction rope 16 is fixedly connected to the take-up shaft 20. The second motor 21 is installed on one side of the stable base 19. The output end of the second motor 21 passes through the stable base 19 and is axially fixedly connected to one end of the take-up shaft 20. When it is necessary to lift and move the round steel ball using a powerful electromagnet 5, the second motor 21 drives the take-up shaft 20. When the winding shaft 20 rotates, the traction rope 16 is wound around the winding shaft 20. At this time, the traction rope 16 moves in the guide grooves on the two guide wheels 18. The guide wheels 18 support the traction rope 16 to roll, thereby causing the traction rope 16 to pull the base plate 15 and the powerful electromagnet 5 to rise or fall. When the base plate 15 and the powerful electromagnet 5 rise or fall, the guide rod 14 slides vertically in the sliding hole opened on the fixed block 13, thereby preventing the base plate 15 and the powerful electromagnet 5 from shaking.

[0020] Working principle: When it is necessary to feed round steel balls, a large number of round steel balls are transported to the storage tank 1 through the discharge chute 22. Then, the first motor 12 drives the gear 11 to rotate. Due to the meshing of the gear 11 and the toothed plate 7, the fixed frame 8 and the moving platform 3 are moved. During the movement of the moving platform 3, the bottom end of the moving platform 3 slides in the sliding groove 9, thereby supporting the moving platform 3 to move stably in the storage tank 1 and the unloading box 2. When the moving platform 3 reaches the storage tank 1, it stops. Then, the second motor 21 drives the winding shaft 20 to rotate. When the winding shaft 20 rotates, the traction rope 16 wound on the winding shaft 20 is unwound. The traction rope 16 moves within the guide grooves on the two guide wheels 18. At this time, the guide wheels 18 support the traction rope 16 to roll, thereby causing the traction rope 16 to pull the base plate 15 and the powerful electromagnet 5 to descend, so that the powerful electromagnet 5 contacts the round steel ball in the storage tank 1 and attracts the round steel ball. Then, the second motor 21 rotates in the opposite direction, thereby driving the powerful electromagnet 5 to rise, thereby lifting the attracted round steel ball. Then, the moving table 3 continues to move to the feeding box 2, controlling the powerful electromagnet 5 to release the attraction of the round steel ball, so that the round steel ball falls into the feeding box 2, thereby feeding the round steel ball into the ball mill through the feeding box 2.

[0021] It should also be noted that when the base plate 15 and the powerful electromagnet 5 are rising or falling, the guide rod 14 slides vertically within the sliding hole opened on the fixed block 13, thereby preventing the base plate 15 and the powerful electromagnet 5 from shaking.

[0022] In addition, the powerful electromagnet 5 is a common existing device on the market. It can control the strength of the suction through an electrical system, thereby enabling the quantity and weight of the steel balls to be added.

[0023] It should also be noted that the traction rope 16 can be selected from high-strength ropes, such as steel wire ropes or iron chains, depending on the actual situation.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
