Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball adding device for a ball mill. Background Art

[0002] At present, most of the existing thermal power plants use limestone and gypsum wet methods for flue gas desulfurization. Many thermal power plants use limestone wet pulping systems, in which wet ball mills play an important role.

[0003] The Chinese utility model patent with patent application number 202122857842.7 provides an automatic ball adding device for a limestone wet ball mill. The rotating disk is driven to rotate by a speed regulating motor. When the feed port on the rotating disk corresponds to the conduit port, the grinding balls are fed. By adjusting the speed of the speed regulating motor, the grinding ball feeding speed can be controlled to meet the use requirements; the fixed seat and the end cover are detachably connected by multiple bolts, and the clamping ring 1 and the clamping ring 2 are connected in cooperation to fix the feed hopper, thereby facilitating the disassembly of the conduit and the feed hopper, and facilitating maintenance personnel to repair it; the automatic ball adding device for a limestone wet ball mill has a simple structure and is easy to disassemble.

[0004] However, during the use of the above device, it was found that the grinding balls in the feed hopper passed through the feed port on the rotating disk and entered the conduit. When the feed port corresponded to the conduit port, multiple grinding balls would easily enter the conduit port at the same time, causing blockage and accumulation between the grinding balls, affecting the entry of the grinding balls into the ball mill. In addition, the conduit of the equipment did not have good control over the entering grinding balls, which easily led to multiple grinding balls in the conduit entering the ball mill at the same time. Multiple grinding balls were prone to collision when entering, which easily led to uneven grinding. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figures 1-4 The ball mill ball adding device shown in the figure includes a ball mill body 1, a connecting frame 11 is provided on one side of the ball mill body 1, the ball mill body 1 is connected to the feeding assembly 2 through the connecting frame 11, and the bottom of the feeding assembly 2 is connected to the connecting assembly 3, which is used to connect the ball mill body 1 and the feeding assembly 2;

[0022] The connecting assembly 3 includes a connecting tube 31, a rotating groove 311 is provided in the middle of the connecting tube 31, a dial 33 is rotatably connected to the inner portion of the rotating groove 311, and a dial plate is provided on the dial 33;

[0023] A rotary box 32 is provided on one side of the connecting tube 31. A rotary motor 37 is provided inside the rotary box 32. The output end of the rotary motor 37 is connected to a rotary disk 36. The rotary disk 36 is provided with an arc-shaped array of gear blocks. The rotary disk 36 meshes with a helical gear 35 through the gear blocks. A rotating shaft 34 is provided on one side of the helical gear 35. The helical gear 35 is connected to the dial 33 through the rotating shaft 34.

[0024] The feeding assembly 2 includes a feeding box 21, a motor box 22 is provided on the top of the feeding box 21, a feeding port 25 is provided on one side of the motor box 22, and a discharge port 27 is provided at the bottom of the feeding box 21;

[0025] A feeding motor 23 is installed inside the motor box 22. The output end of the feeding motor 23 is connected to a rotating rod 24. The rotating rod 24 is rotatably connected to the bottom of the feeding box 21. An adjustment plate 26 is fixedly installed on the rotating rod 24.

[0026] The discharge port 27 is connected to the connecting pipe 31 in the connecting assembly 3 .

[0027] In this solution, the balls enter the feeding assembly 2, and the balls in the feeding box 21 enter the connecting pipe 31 through the discharge port 27. When multiple balls stay at the discharge port 27 at the same time, it is easy for the balls to block each other and have difficulty entering the connecting pipe 31. The feeding motor 23 in the motor box 22 is used to control the rotation of the rotating rod 24 so that the adjustment plate 26 on the rotating rod 24 can rotate. When the adjustment plate 26 rotates, the adjustment plate 26 pushes the balls at the discharge port 27, thereby dispersing the multiple balls staying at the discharge port 27, making it easier for subsequent single balls to enter the discharge port 27, thereby realizing that the balls enter the connecting assembly 3 in sequence.

[0028] The connecting assembly 3 is used to control the amount of balls entering the ball mill. The balls entering the connecting assembly 3 from the feeding assembly 2 enter the rotating groove 311 along the connecting pipe 31, and are blocked by the dial 33 and stay in the connecting pipe 31, so that the balls entering the connecting pipe 31 stay in sequence. The rotating motor 37 in the rotating box 32 controls the rotation of the turntable 36. The gear block on the turntable 36 meshes with the bevel gear 35, so that when the turntable 36 rotates, the gear block controls the rotation of the bevel gear 35, thereby rotating the dial 33. When the dial 33 rotates, the dial plate on the dial 33 can push a single ball into the ball mill body 1.

[0029] When the gear on the turntable 36 rotates and disengages from the bevel gear 35, the turntable 36 cannot drive the dial 33 to rotate, so that the dial plate on the dial 33 can prevent subsequent balls from entering the ball mill body 1. There is a large friction between the rotating shaft 34 on the dial 33 and the rotating groove 311, which can prevent the dial 33 from rotating when the balls hit the dial plate. The angle between the two ends of the tooth block on the turntable 36 is the same as the angle between the two dial plates on the dial 33. The turntable 36 and the tooth block are rotated to achieve periodic rotation of the dial 33, thereby periodically pushing a single ball into the ball mill body 1 for grinding, thereby preventing multiple balls from entering the ball mill body 1 at the same time, causing the balls to collide with each other and uneven grinding.
