Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ball mill for frit raw materials. Background Technology

[0002] Ball mills are core equipment in the processing of fused raw materials, primarily used to grind and refine them to meet the particle size requirements of subsequent production. During the grinding process, to ensure the particle size of the ground material meets standards, a filtration structure is typically installed inside the ball mill to screen and separate the ground fused raw materials, preventing substandard coarse material from mixing into the finished product and affecting the quality of subsequent processing.

[0003] In traditional ball mill filtration designs for fused raw materials, circular filter screens are typically installed inside the mill barrel to effectively filter the ground material. However, circular filter screens have significant drawbacks in practical use: due to their annular structure, their installation and removal require precise openings in the mill barrel. Typically, arc-shaped holes with a central angle of at least 180 degrees need to be drilled in the mill barrel wall to provide sufficient space for removal and replacement. However, drilling such large arc-shaped holes significantly weakens the structural integrity of the mill barrel wall, leading to uneven stress distribution and potential stress concentration, deformation, or even cracking during long-term operation. Therefore, we propose a ball mill for fused raw materials. Utility Model Content

[0004] The purpose of this application is to provide a ball mill for frit feedstock to solve the problems mentioned in the background art.

The arc-shaped hole is connected to the annular groove. A rotating ring is rotatably installed in the annular groove. Multiple filter mechanisms are uniformly arranged along the circumference and installed on the side of the rotating ring through multiple fixing mechanisms. The area of ​​the circle formed by the multiple filter mechanisms is equal to the inner cross-sectional area of ​​the ball mill cylinder. A sealing mechanism is installed on the outer side of the ball mill cylinder.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 6 The embodiments provided by this utility model are as follows: A ball mill for frit raw materials includes a frame 1, two feed cylinders 7 are rotatably mounted on the top of the frame 1, a ball mill cylinder 2 is fixedly mounted on the side of the two feed cylinders 7 that are close to each other, and a drive mechanism for driving the ball mill cylinder 2 to rotate is mounted on the top of the frame 1. like Figure 1 As shown, the drive mechanism includes a motor 6 fixedly mounted on the top of the frame 1. A small multi-groove pulley 5 and a large multi-groove pulley 10 are fixedly mounted on the output shaft of the motor 6 and the outer side of the ball mill cylinder 2, respectively. Multiple transmission belts 4 are tensioned on the small multi-groove pulley 5 and the large multi-groove pulley 10. Starting the motor 6 causes the small multi-groove pulley 5 to rotate. This rotation, via the multiple transmission belts 4, drives the large multi-groove pulley 10 and the ball mill cylinder 2 to rotate, thereby causing the molten material and steel balls to rotate. The steel balls grind the molten material, and the ground material is discharged through an arc-shaped filter plate 12 and another feed cylinder 7.

[0019] An annular groove 19 is provided on the inner wall of the ball mill cylinder 2. An arc-shaped hole 20 communicating with the inside of the ball mill cylinder 2 is provided on the outer side of the ball mill cylinder 2. The arc-shaped hole 20 is connected to the annular groove 19. A rotating ring 18 is rotatably installed in the annular groove 19. Multiple filter mechanisms are installed on the side of the rotating ring 18 through multiple fixing mechanisms. The area of ​​the circle formed by the multiple filter mechanisms is equal to the inner cross-sectional area of ​​the ball mill cylinder 2. like Figure 3 As shown, the fixing mechanism includes two mounting blocks 14 fixedly installed on the side of the arc-shaped frame 11. Two grooves are formed on the side of the rotating ring 18, and the two mounting blocks 14 extend into these grooves respectively. Bolt holes are formed on the sides of both mounting blocks 14, and cross bolts 13 are installed in these holes. Bolt slots are formed on the inner walls of the two grooves, and the cross bolts 13 are threaded into these slots respectively. The mounting blocks 14 are adapted to the grooves. After the mounting blocks 14 are installed in the grooves, the side of the mounting blocks 14 away from the arc-shaped sealing plate 8 is on the same plane as the side of the rotating ring 18, and the side of the mounting blocks 14 near the arc-shaped sealing plate 8 is located within the groove, thus not affecting the rotation of the rotating ring 18. Simultaneously, the arc-shaped frame 11 contacts the side of the rotating ring 18 extending into the annular groove 19, thus also not affecting the rotation of the rotating ring 18.

[0020] like Figure 6 As shown, the filtration mechanism includes an arc-shaped frame 11, on the inner wall of which an arc-shaped filter plate 12 is fixedly installed. A groove 23 is formed on the outer arc of the arc-shaped frame 11. The arc-shaped filter plate 12 is used to filter the ball-milled raw material.

[0021] A sealing mechanism is installed on the outer side of the ball mill cylinder 2. The sealing mechanism corresponds to the position of the arc-shaped hole 20 and is installed in conjunction with the rotating ring 18.

[0022] like Figure 3 As shown, the outer surface of the rotating ring 18 has multiple evenly circumferentially arranged actuating grooves 17, and multiple actuating blocks 16 are fixedly installed on the inner wall of the actuating grooves 17. The actuating blocks 16 facilitate the rotation of the rotating ring 18.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the sealing mechanism includes an arc-shaped sealing plate 8, which is fixedly connected to the outer side of the ball mill cylinder 2 by two sealing bolts 9. The arc-shaped sealing plate 8 corresponds to the arc-shaped hole 20. Two limiting rods 15 are fixedly installed on the inner wall of the arc-shaped sealing plate 8. One end of each limiting rod 15 extends into two adjacent actuating grooves 17, and the sides of the two limiting rods 15 that are close to each other contact the inner walls of the two actuating grooves 17 that are close to each other. By inserting the two limiting rods 15 into the two actuating grooves 17, the rotating ring 18 can be limited. The arc-shaped sealing plate 8 facilitates the sealing of the arc-shaped hole 20.

[0024] like Figure 1 As shown, a steel column feed gate 3 is installed on the top of the ball mill cylinder 2. The steel column feed gate 3 facilitates the introduction of steel balls. The central angle of the arc-shaped hole 20 is larger than the central angle of the arc-shaped frame 11. The advantage of this setting is that the arc-shaped frame 11 can be taken out from the arc-shaped hole 20. There are at least four arc-shaped frames 11. The advantage of this setting is that the central angle of the arc-shaped hole 20 is small, making the structure of the ball mill cylinder 2 stable.

[0025] like Figure 6 As shown, a slot 22 is provided on one side of the arc-shaped frame 11, and a pin 21 is fixedly installed on the other side of the arc-shaped frame 11. The pin 21 is adapted to the slot 22. After all the arc-shaped frames 11 are installed, each pin 21 is located in the corresponding slot 22, so that the overall arc-shaped frame 11 is stably connected after installation.

[0026] Working principle: During use, steel balls can be placed through the steel column feed gate 3. Wear-resistant plates are provided on the inner wall of the ball mill cylinder 2, and molten blocks can be introduced through a feed cylinder 7. By starting the motor 6, the small multi-groove pulley 5 can be rotated. The rotation of the small multi-groove pulley 5 drives the large multi-groove pulley 10 and the ball mill cylinder 2 to rotate through multiple transmission belts 4, thereby causing the molten material and steel balls to rotate. The molten material can be ground by the steel balls. The ground material is discharged through the arc-shaped filter plate 12 and another material cylinder 7. When maintenance of the arc-shaped filter plate 12 is required, turn off the motor 6, then remove the two sealing bolts 9 and take out the arc-shaped sealing plate 8. The movement of the arc-shaped sealing plate 8 will cause the two limit rods 15 to move out of the two actuating slots 17 respectively. At this time, the rotating ring 18 can rotate. Then, remove the two cross bolts 13 to take out one arc-shaped frame 11. Then, by actuating the actuating block 16, the rotating ring 18 can be rotated. The rotation of the rotating ring 18 will cause the remaining arc-shaped frames 11 to rotate, so that the remaining arc-shaped frames 11 will rotate to the position corresponding to the arc-shaped hole 20 in sequence. Then, remove the two cross bolts 13 on the remaining arc-shaped frames 11 in sequence, so that all the arc-shaped frames 11 can be disassembled for easy maintenance.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
