Description

Technical Field

[0001] The invention relates to the technical field of ball mills, in particular to a ball adding device for a ball mill and a construction method thereof. Background Art

[0002] Ball mills are key equipment for pulverizing materials after crushing. They are widely used in industries such as cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics. During ball mill operation, steel balls are subject to continuous wear due to friction and collision with the material, liner, and other components, affecting the milling process. To ensure that the milling process meets process requirements, the steel ball ratio must be maintained consistently over time, requiring regular replacement of worn steel balls.

[0003] Existing devices primarily add steel balls to a ball mill via a chute. Much of the prior art is similar to a ball-adding device for a ball mill and its construction method. Publication No. CN220160131U describes a structure comprising a feed bin, a ball discharge assembly, and a chute. The discharge end of the feed bin is connected to the feed end of the ball discharge assembly via a connecting chute. A vibrating assembly is provided at the bottom of the connecting chute, and the feed end of the chute is connected to the discharge end of the ball discharge assembly. This invention effectively prevents raw material from clogging during the material guiding process, however, there are still areas for improvement.

[0004] The existing device mainly guides the steel balls into the interior of the ball mill through a chute control, which makes it difficult for some devices to quantitatively transport steel balls into the interior of the ball mill, resulting in inconvenience in accurately controlling the amount of steel balls added. At the same time, some devices find it difficult to automatically detect and prompt the lack of balls in the ball storage bin, which makes it inconvenient for operators to replenish steel balls in time, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a ball adding device for a ball mill and a construction method thereof are proposed. Summary of the Invention

[0005] The object of the present invention is to provide a ball adding device for a ball mill and a construction method thereof, so as to solve the problem that the existing devices in the prior art mentioned in the above background technology mainly guide the steel balls into the interior of the ball mill through chute control, which makes it difficult for some devices to quantitatively transport steel balls to the interior of the ball mill, thereby making it inconvenient to accurately control the amount of steel balls added. At the same time, some devices find it difficult to automatically detect and prompt the lack of balls in the ball storage bin, thereby making it inconvenient for operators to replenish steel balls in time.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a ball adding device for a ball mill and a construction method thereof, comprising a fixed frame, a ball storage bin slidably connected to the interior of the fixed frame, a telescopic tube fixedly connected to the bottom of the ball storage bin, a ball supply barrel fixedly connected to the bottom of the telescopic tube, a transmission box fixedly connected to the right side of the ball supply barrel, and a controller fixedly connected to the middle portion of the right side of the transmission box;

[0007] A ball supply mechanism is provided inside the transmission box, and the ball supply mechanism includes a servo motor. The bottom of the servo motor is fixedly connected to the middle of the top of the transmission box. A detection mechanism is provided on the outside of the ball storage bin, and the detection mechanism includes an edge plate. The edge plate is fixedly connected to the front and rear sides of the ball storage bin.

[0008] Preferably, a transmission worm is fixedly connected to the middle of the bottom of the servo motor, the bottom end of the transmission worm is movably connected to the bottom of the inner wall of the transmission box, and the front and rear sides of the outer wall of the transmission worm are meshed with transmission worm wheels.

[0009] Preferably, a rotating rod is fixedly connected to the inner wall of the transmission worm gear, the right end of the rotating rod is movably connected to the right side of the inner wall of the transmission box, and the left end of the rotating rod passes through the right side wall of the ball supply cylinder and is movably connected to the left side of the inner wall of the ball supply cylinder.

[0010] Preferably, an auger is fixedly connected to the outer wall of the rotating rod, a pair of the auger rotates in opposite directions, and the length of the auger spiral pitch is slightly larger than the length of the steel ball diameter.

[0011] Preferably, telescopic rods are fixedly connected to both sides of the bottom of the side plate, the bottom of the telescopic rods is fixedly connected to the bottom of the inner wall of the fixing frame, the bottom of the side plate is located at the outer ring of the telescopic rod and is fixedly connected to a spring, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the fixing frame.

[0012] Preferably, a sensing block is fixedly connected to the lower right side of the ball storage bin, a proximity switch sensor is fixedly connected to the upper inner wall of the right side of the fixing frame, and a signal light is fixedly connected to the upper right side of the fixing frame.

[0013] A construction method for a ball adding device for a ball mill, characterized by comprising the ball adding device for a ball mill according to claim 1, and specifically operating as follows:

[0014] When it is necessary to supply the steel balls, the servo motor is first started through the controller. The servo motor drives the transmission worm to limit the rotation. The transmission worm engages and drives a pair of transmission worm wheels to rotate synchronously in the opposite direction. The transmission worm wheels drive the rotating rod to limit the rotation. The rotating rod drives the auger to rotate synchronously, so that the pair of augers drive the steel balls to move to the left, realizing the steel ball supply operation.

[0015] When the ball storage bin needs to be inspected, when there is no ball in the bin, the spring drives the side plate to slide upward, and the side plate drives the ball storage bin to slide synchronously.

[0018] 2. The present invention uses the structures of the edge plate, telescopic rod, spring, sensing block, proximity switch sensor and signal light in the detection mechanism.

Some devices can automatically detect and prompt the ball-out status of the ball storage bin, which is convenient for the operator to replenish steel balls in time, thereby improving the early warning and practicality of the device.

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.

[0025] See also Figures 1-4 , an embodiment provided by the present invention:

[0026] A ball adding device for a ball mill and a construction method thereof, comprising a fixed frame 11, a ball storage bin 12 being slidably connected to the interior of the fixed frame 11, a telescopic tube 13 being fixedly connected to the bottom of the ball storage bin 12, a ball supply cylinder 14 being fixedly connected to the bottom of the telescopic tube 13, a transmission box 15 being fixedly connected to the right side of the ball supply cylinder 14, and a controller 16 being fixedly connected to the middle portion of the right side of the transmission box 15;

[0027] The transmission box 15 is provided with a ball supply mechanism 2 inside, and the ball supply mechanism 2 includes a servo motor 21. The bottom of the servo motor 21 is fixedly connected to the middle of the top of the transmission box 15. The middle of the bottom of the servo motor 21 is fixedly connected to a transmission worm 22. The bottom end of the transmission worm 22 is movably connected to the bottom of the inner wall of the transmission box 15. The front and rear sides of the outer wall of the transmission worm 22 are meshed with a transmission worm wheel 23. Through this design, the servo motor 21 drives the transmission worm 22 to rotate in a limited position, so that the transmission worm 22 engages and drives a pair of transmission worm wheels 23 to rotate synchronously in the opposite direction. A rotating rod 24 is fixedly connected to the inner wall, and the right end of the rotating rod 24 is movably connected to the right side of the inner wall of the transmission box 15. The left end of the rotating rod 24 passes through the right side wall of the ball supply cylinder 14 and is movably connected to the left side of the inner wall of the ball supply cylinder 14. Through this design, the transmission worm gear 23 drives the rotating rod 24 to rotate in a limited manner. An auger 25 is fixedly connected to the outer wall of the rotating rod 24. A pair of augers 25 rotate in opposite directions. The length of the spiral pitch of the augers 25 is slightly larger than the length of the diameter of the steel balls. Through this design, a pair of augers 25 drive the steel balls to move to the left, which is convenient for quantitatively supplying balls to the interior of the ball mill.

[0028] The outer ring of the telescopic rod 32 along the bottom of the side plate 31 is fixedly connected to the spring 33, and the bottom of the spring 33 is fixedly connected to the bottom of the inner wall of the fixing frame 11.

[0029] Working principle: When it is necessary to supply steel balls, the servo motor 21 is first started through the controller 16. The servo motor 21 drives the transmission worm 22 to limit rotation. The transmission worm 22 engages and drives a pair of transmission worm wheels 23 to rotate synchronously in the opposite direction. The transmission worm wheel 23 drives the rotating rod 24 to limit rotation. The rotating rod 24 drives the auger 25 to rotate synchronously, so that the pair of auger 25 drives the steel balls to move to the left, thereby realizing the ball supply operation of the steel balls.

[0030] When the ball storage bin 12 needs to be inspected, when there is no ball in the ball storage bin 12, the spring 33 drives the side plate 31 to slide upward, and the side plate 31 drives the ball storage bin 12 to slide synchronously, and the ball storage bin 12 drives the sensing block 34 to approach the proximity switch sensor 35, so that the proximity switch sensor 35 activates the signal light 36 to prompt that the ball storage bin 12 is out of balls, thereby completing the inspection operation of the ball storage bin 12, and the operation ends here.
