Abstract
Description
Technical Field
[0001] The present application relates to the technical field of ball mill production auxiliary devices, and in particular to a ball adding device for a ball mill. Background Art
[0002] During the smelting process, the ball mill is used to crush and grind coarse ore. The principle is: by adding ore and steel balls into the ball mill with a certain specific gravity, when the ball mill rotates, the steel balls will be continuously thrown up, and when the steel balls fall, they will impact the ore, thereby achieving crushing. At the same time, a large number of steel balls will continuously collide and rub in the ball mill, and the coarse ore can be ground into only fine ore with smaller particle size, which is convenient for subsequent processing.
[0003] In order to improve the grinding effect of the ball mill, it is critical to ensure the accuracy of the specific gravity of the added ore and steel balls. If too much balls are added, it is easy to cause the steel balls to pile up in the ball mill, thereby reducing the grinding effect; if not enough balls are added, it is easy to cause the ore to not reach the required grinding standard when the steel balls are worn out, thus affecting the quality of the ore. When adding balls, the steel balls are usually rolled into the ball mill by gravity. The ball mills used in metallurgy are generally large-scale, and their feed ports are 1-2 meters above the ground. Therefore, it is necessary to set up a working platform for adding balls. The height of the working platform is usually between 3-4 meters. When adding balls, the steel balls need to be transported to the working platform.
[0004] At present, ball adding is divided into manual adding and mechanical adding. Manual adding requires driving assistance, and the staff needs to operate close to the suspended steel ball bucket and the running feed belt. Not only is the labor intensity high, but it is also prone to safety accidents such as lifting injuries and mechanical injuries. The automatic ball adding machines on the market are expensive, and the ball adding accuracy needs to be improved. Utility Model Content

[0027] See also Figure 1-5 The ball mill ball adding device includes a working platform 2, a lifting mechanism 3, a weighing mechanism 4, and a feeding hopper 5. The working platform 2 is fixedly installed next to the ball mill 1. A steel structure frame with a height of 3.2m, a length of 4.5m, and a width of 3.7m is built. A 14m long steel structure frame with a 6mm pattern plate is used. 2 A working platform 2 is provided, and a platform guardrail is made of φ50mm welded pipe and 50mm flat iron. A weighing mechanism 4 for weighing steel balls is installed on the working platform 2, and the weighing mechanism 4 is connected to the ball mill 1 through a feed hopper 5, so as to facilitate automatic ball adding. A lifting mechanism 3 for transporting small balls is also installed on the side of the working platform 2. The feeding end of the lifting mechanism 3 is arranged on the floor of the factory building, and the discharging end thereof corresponds to the weighing mechanism 4.
[0028] See also Figure 2The lifting mechanism 3 includes a lifting tube 31, a feed trough 32, a motor 35, a rotating shaft 36, and a spiral blade 37. The lifting tube 31 is tilted, one end of which is fixedly installed on the factory floor through a support 38, and the other end is fixedly connected to the ground through a support frame 39. A rotating shaft 36 is rotatably installed in the lifting tube 31, and a spiral blade 37 is fixedly connected to the rotating shaft 36. A first discharge port 34 corresponding to the weighing mechanism 4 is provided at the front end of the lifting tube 31, and a detachable tail cover 33 is fixedly connected to the rear end thereof. Optionally, the tail cover 33 is fixedly connected to the lifting tube 31 by bolts and nuts, and a motor 35 is fixedly installed on the tail cover 33. The output shaft of the motor 35 is fixedly connected to the rotating shaft 36. The motor 35 can drive the rotating shaft 36 to rotate, so that the steel balls are lifted and transported through the spiral blade 37. By setting a detachable tail cover 33, it is convenient to maintain and clean the lifting tube 31. When in use, start the motor 35 and add the steel balls into the feed trough 32. The steel balls are lifted to the working platform 2 driven by the spiral blades 37 and fall into the weighing mechanism 4 from the first discharge port 34. The balls can be added directly on the factory floor through the lifting mechanism 3, and there is no need to lift the steel balls to the working platform 2 by a crane, thus avoiding lifting injuries and mechanical injuries caused by lifting, thereby improving production safety.
[0029] See also Figure 3 , 4 The weighing mechanism 4 includes a base 41, a weighing sensor 42, a weighing box 43, a discharge plate 44, an electric telescopic rod 45, and a slide 46. The base 41 is fixedly connected to the working platform 2, and the top of the base 41 is connected to the weighing box 43 through the weighing sensor 42. The position of the weighing box 43 corresponds to the lifting mechanism 3, so that the steel ball dropped from the first discharge port 34 directly falls into the weighing box 43. The discharge plate 44 is hinged on the side of the weighing box 43. A connecting block 47 is provided, one end of the electric telescopic rod 45 is hinged to the side wall of the weighing box 43, and the other end is hinged to the connecting block 47. The opening and closing of the discharge plate 44 can be controlled by extending or shortening the electric telescopic rod 45, so as to facilitate automatic ball adding. A slide groove 46 is also provided on the outer side of the discharge plate 44. The slide groove 46 is fixedly installed on the working platform 2 through a bracket 48, and the slide groove 46 is used to receive the steel balls in the weighing box 43 and transport the steel balls to the feed hopper 5.
[0030] Furthermore, to facilitate the control of the device, the motor 35, the weighing sensor 42, and the electric telescopic rod 45 are all electrically connected to the PLC and controlled by the PLC. When in use, the lifting mechanism 3 intermittently transports batches of steel balls to the weighing box 43, and the weighing sensor 42 performs real-time weighing. When the weight of the steel balls reaches the standard, the PLC controls the motor 35 to stop, and the lifting mechanism 3 no longer transports the steel balls to ensure the accuracy of adding balls. The electric telescopic rod 45 is extended by the PLC to rotate the discharge plate 44 around the hinge, thereby opening the weighing box 43, and the steel balls roll into the feed hopper 5 from the chute 46.
[0031] Furthermore, the bottom surface of the weighing box 43 is an inclined surface, and the side close to the discharge plate 44 is lower, and the side away from the discharge plate 44 is higher, so as to facilitate the rolling of the steel ball.
[0032] See also Figure 5 The feed hopper 5 includes a hopper body 51, a baffle 52, and a positioning ring 54. The hopper body 51 is a funnel-shaped structure. The top of the hopper body 51 is fixedly connected with a baffle 52 for blocking the steel balls, thereby preventing the steel balls from rushing out of the hopper body 51 and ensuring the stability of the feeding. A connecting port 53 corresponding to the slide groove 46 is provided on the baffle 52, thereby facilitating the installation of the slide groove 46. A positioning ring 54 is also provided on the hopper body 51, and an installation port corresponding to the hopper body 51 is provided on the working platform 2. After the bottom of the hopper body 51 passes through the installation port, it is first clamped at the installation port through the positioning ring 54, and then the positioning ring 54 is fixedly connected to the working platform 2 by screws, thereby ensuring the stability of the feed hopper 5. The bottom of the hopper body 51 is a second discharge port 55, and the second discharge port 55 is connected to the feed shuttle tube of the ball mill 1 through a pipeline, thereby facilitating the addition of steel balls into the ball mill 1.
[0033] Specific working process:
[0034] Start the motor 35 and add the steel balls into the feed trough 32. Driven by the spiral blades 37, the steel balls fall into the weighing box 43 from the first discharge port 34 and are weighed by the weighing sensor 42. When the weight reaches the standard, the motor 35 is stopped by the PLC control, and the lifting mechanism 3 immediately stops feeding to ensure the accuracy of adding balls. The electric telescopic rod 45 is extended by the PLC control to open the discharge plate 44, and the steel balls roll into the feed hopper 5 from the chute 46 and finally enter the ball mill 1 to complete the ball adding.
