Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and more specifically, to a discharge device for a ball mill. Background Technology

[0002] Ball mills are widely used grinding equipment in industries such as mining, building materials, metallurgy, and chemicals. They are primarily used to further grind crushed solid materials into fine powder. They achieve material pulverization through the impact and grinding action of internal media, such as steel balls and steel segments. Ball mills are characterized by a wide range of applicable materials, high grinding efficiency, and adjustable product particle size. The core structure of a ball mill includes the cylinder, grinding media, feeding and discharging devices, and a transmission system. The cylinder is welded from steel plates, and the inner wall is often lined with wear-resistant plates to extend its service life. The grinding media are selected based on the material characteristics and grinding requirements, using different materials and specifications. The transmission system... The ball mill uses a motor to drive the cylinder to rotate, providing power for the grinding process. When the ball mill is working, the motor drives the cylinder to rotate through the transmission system. The grinding media steel balls inside the cylinder rise to a certain height with the cylinder and then fall or are thrown down under the action of gravity. The material enters the cylinder from the feed end and is crushed and refined under the impact, compression and grinding action of the media. As the cylinder continues to rotate, the material moves axially in the chamber. After being gradually ground in multiple chambers, the material with qualified particle size is discharged through the discharge device, completing the grinding process. Since the material is discharged directly along the discharge head of the cylinder, it is necessary to perform a discharge guiding operation on the material.

[0003] In related technologies, during the use of ball mills, the ball mill is generally guided to receive and use materials by installing an inclined discharge guide bucket at the bottom of the discharge end.

[0004] However, in the current use of ball mills, the guide buckets are generally fixed at the discharge end of the ball mill by brackets and bolts. Since the discharge requirements of different ball mills will change with the actual use, the guide buckets are difficult to effectively assist the ball mill in adapting to the external discharge requirements, which affects the discharge flexibility and adaptability of the ball mill.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a discharge device for a ball mill, including a base frame 1 and a discharge guide mechanism. A ball mill 2 is installed on the top of the base frame 1, and a discharge head 3 is installed on the left side of the ball mill 2. A discharge receiving guide medium that can be raised, lowered, and angled can be formed at the bottom of the discharge head 3, so that the user can adjust the discharge receiving guide of the ball mill 2 according to the actual use of the ball mill 2, avoiding the situation where it is difficult to adjust the discharge to meet the actual use needs when using the ball mill 2, thus improving the discharge flexibility and adaptability of the ball mill 2.

[0031] Reference Figures 1-4 In a preferred embodiment, the discharge guiding mechanism includes a support base 4, which is movably connected to both sides of the left side of the base frame 1. A guide rail 5 is movably connected to the top of the support base 4. An adjustment groove 6 is formed on the top of the support base 4. Both sides of the bottom of the guide rail 5 are movably connected to adjustment seats 7 located inside the adjustment groove 6 via hinge supports. An adjustment and positioning mechanism is set at the top of the inner wall of the adjustment groove 6. By using the moving wheels at the bottom of the support base 4, the support base 4 is pushed to move the guide rail 5 to the bottom of the discharge head 3 in coordination with the adjustment seats 7. The guide rail 5 can be moved up and down by hand. Since the guide rail 5 and the adjustment seats 7 are movably connected via hinge supports, the front and rear sides of the guide rail 5 can be adjusted. The height of seat 7 is adjusted to change the height and angle of the guide rail 5 to adapt to the actual discharge requirements of ball mill 2. The positioning mechanism includes positioning hole 8, positioning column 9 and positioning port 10. Positioning hole 8 is opened at the top of the inner side of the inner wall of adjustment groove 6. Positioning column 9 is movably connected inside positioning hole 8. Positioning port 10 is opened inside the adjustment seat 7. The outer side of positioning column 9 is located inside positioning port 10. This allows for insertion and positioning between the adjusted adjustment seat 7 and support seat 4, so that the user can position the guide rail 5 after adjustment, avoiding the difficulty of positioning the adjustment seat 7 during use. Therefore, the adjustment and positioning convenience of adjustment seat 7 is improved.

[0032] Reference Figures 2-4In a preferred embodiment, a connecting seat 11 is fixedly connected to the top of the inner side of the support base 4. The connecting seat 11 has a connecting cavity 12 that communicates with the positioning hole 8. The inner side of the positioning post 9 is located inside the connecting cavity 12, which allows for translational connection between the positioning post 9 and the support base 4, preventing the positioning post 9 from shifting during use. This improves the connection effect between the positioning post 9 and the support base 4. A spring 13 is provided inside the connecting cavity 12. One end of the spring 13 is connected to the inner wall of the connecting cavity 12, and the other end of the spring 13 is connected to the surface of the positioning post 9. This allows for an outward pushing force to be applied to the positioning post 9, ensuring the stability of the insertion and positioning of the positioning post 9.

[0033] Reference Figures 2-4 In a preferred embodiment, a sleeve 14 located outside the spring 13 is fixedly connected to both the surface of the positioning post 9 and the inner wall of the connecting cavity 12. A limiting block 15 that contacts the support seat 4 is fixedly connected to the top of the positioning post 9. This can prevent the spring 13 from slipping between the positioning post 9 and the connecting cavity 12 and restrict the outward movement of the positioning post 9. Therefore, the working stability of the spring 13 in conjunction with the positioning post 9 is improved. A lifting hole 16 is opened on the inner side of the top of the positioning post 9. A lifting post 17 is movably connected inside the lifting hole 16. This allows for lifting and lowering the positioning post 9 and the connecting seat 11 for positioning. Therefore, the ease of operation of the positioning post 9 is improved.

[0034] Reference Figures 2-4 In a preferred embodiment, a movable opening 18 is provided on the outer side of the top of the inner wall of the connecting cavity 12. The lifting column 17 passes through the connecting seat 11 through the movable opening 18. The top of the lifting column 17 is fixedly connected to the lifting plate 19, which provides space and medium for the user to move the lifting column 17, thus improving the ease of use of the lifting column 17. A recessed hole 20 is provided at the bottom of the inner wall of the connecting cavity 12. The recessed hole 20 is located inside the positioning column 9, which provides space for lifting and lowering insertion and positioning, thus improving the insertion and positioning effect of the lifting column 17.

[0035] Specifically, the working process or principle of the discharge device of this ball mill is as follows: During use, the moving wheels on both sides of the bottom of the support base 4 push the support base 4 in conjunction with the adjusting base 7 to move the guide rail 5 to the bottom of the discharge head 3. Based on the discharge receiving height of the discharge head 3 and the actual discharge requirements of the ball mill 2, the lifting plate 19, in conjunction with the moving port 18, and the lifting column 17, in conjunction with the lifting hole 16, apply an inward pushing force to the positioning column 9, causing the positioning column 9 to disengage from the positioning port 10 and enter the positioning hole 8. At this time, The positioning pin 9 moves inside the connecting cavity 12. The connecting cavity 12, in conjunction with the connecting seat 11, performs a movable connection and anti-displacement operation between the positioning pin 9 and the support seat 4. As the positioning pin 9 and the lifting pin 17 move inward, when the lifting hole 16 aligns with the sinking hole 20, the lifting pin 17 moves downward into the sinking hole 20 under its own weight, performing a plug-in positioning operation between the moved positioning pin 9 and the connecting seat 11. At this time, the spring 13 contracts due to the movement of the positioning pin 9. Simultaneously, the sleeve 14 connects the spring 13 and the positioning pin. 9 is connected to the connecting cavity 12 to prevent deviation. Then, the guide rail 5 is moved up and down by hand to adjust its height and tilt angle. At this time, the adjusting seat 7 moves with the guide rail 5 inside the adjusting groove 6 to adjust the connection between the guide rail 5 and the support seat 4. Since the adjusting seat 7 and the guide rail 5 are connected by a hinge support, when the guide rail 5 is tilted, the height of the adjusting seat 7 before and after the guide rail 5 is adjusted. After the height and tilt angle of the guide rail 5 are adjusted, the lifting plate 19 is used to drive the lifting column 17 to move upward and disengage from the sinking hole 20. At this time, the contracted spring 13 applies an outward pushing force to the positioning column 9, so that the positioning column 9 enters the positioning port 10. The adjusted adjusting seat 7 and the support seat 4 are inserted and positioned to support and stabilize the adjusted guide rail 5. When the ball mill 2 discharges material through the discharge head 3, the guide rail 5 receives and guides the material discharged from the discharge port to meet the actual discharge requirements of the ball mill 2.

[0036] It should be noted that the base frame 1, the ball mill 2, and the discharge head 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail here.
