Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to water flow monitoring equipment used for ball mills. Background Art

[0002] A ball mill is a commonly used grinding or grinding equipment. Its working principle is that when the cylinder rotates, the spherical grinding body is lifted up due to the friction of the inner wall of the cylinder. When its rising angle exceeds the repose angle, the grinding body falls down. The material is crushed by the impact of the falling grinding body and the grinding action between the grinding body and the inner wall of the cylinder. Ball mills are mainly divided into dry ball mills and wet ball mills. Dry ball mills have a wide range of uses, while wet ball mills are mainly used for grinding water-insoluble materials. When using a wet ball mill, it is usually necessary to inject clean water in a certain proportion to the material into the ball mill.

[0003] As materials are continuously added to the existing wet ball mill, the water level in the wet ball mill will rise and overflow when it reaches the drainage pipe. As the water overflows, the original optimal ratio of water to material is broken, affecting the grinding quality. Since it is impossible to monitor the overflow of water, it is impossible to accurately add clean water to the ball mill. Therefore, water flow monitoring equipment for the ball mill is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a water flow monitoring device for a ball mill to solve the problem that as the material is continuously added to the existing wet ball mill, the water level in the wet ball mill rises and overflows when it reaches the drainage pipe position.

One end of the water delivery pipe 3 is connected, and the other end of the water delivery pipe 3 is connected to the first water pump 5. A water tank 6 is arranged below the first water pump 5, and a controller 7 is installed on the front surface of the water tank 6. The top of the water delivery pipe 3 is connected to the straight pipe 201, and the bottom of the water delivery pipe 3 is connected to the water tank 6 through the first water pump 5. The water inside the water tank 6 is injected into the straight pipe 201 through the water delivery pipe 3 through the first water pump 5, and finally flows into the cylinder 1 from the straight pipe 201. Since the inclined pipe 202 is installed on the right side of the straight pipe 201, the water flow can be prevented from flowing back in the feeding mechanism 2. A flow regulating valve 4 is installed on the outside of the water delivery pipe 3, and the inside of the cylinder 1 An inner lining plate 11 is installed on the wall, and a drainage pipe 12 is arranged on the left side of the cylinder 1. A large gear 8 is fixedly installed on the outer surface of the cylinder 1, and a small gear 9 is meshed and connected below the large gear 8, and the small gear 9 is connected to the output end of the motor 10. The motor 10 is started to drive the small gear 9 to rotate through the output shaft. Under the meshing action of the small gear 9 and the large gear 8, the large gear 8 drives the cylinder 1 to rotate, and the steel balls inside the cylinder 1 continuously collide with the materials to crush the materials. A flow rate sensor 13 is installed on the outside of the drainage pipe 12. The right end of the drainage pipe 12 passes through the middle of the left side of the cylinder 1 through the bearing, and the cylinder 1 passes through the drainage pipe 12. The pipe 12 is connected to the filter box 14. This setting allows the drainage pipe 12 to remain stationary when the cylinder 1 rotates. As the material is continuously put in, the overflow water in the cylinder 1 is discharged from the drainage pipe 12. Since a flow rate sensor 13 is installed on the drainage pipe 12, the loss rate of water inside the cylinder 1 is monitored by the flow rate sensor 13. The flow rate sensor 13 transmits the monitoring signal to the controller 7. After analysis, the controller 7 issues an instruction to the flow regulating valve 4, so that the water inlet of the water supply pipe 3 and the water outlet of the drainage pipe 12 are balanced, so that the ratio of material to water inside the cylinder 1 is always maintained at the optimal ratio, which is convenient for use;

[0024] The filter box 14 is arranged at the lower end of the drainage pipe 12, and a discharge pipe 17 is installed on the left side of the filter box 14, a second water pump 18 is installed on the right side of the filter box 14, and a return pipe 19 is connected to the right side of the second water pump 18, a filter plate 15 is installed inside the filter box 14, and concave plates 16 are arranged on the left and right sides of the filter plate 15, and the filter plate 15 is slidably connected to the cylinder 1 through the concave plates 16, and the crushed material particles are small and can be easily discharged from the cylinder 1 with the water flow. Since the material is insoluble in water, The material is intercepted by the filter plate 15 and then discharged from the discharge pipe 17. The discharge pipe 17 is arranged to be an inclined structure to facilitate the discharge of the material. Since the filter plate 15 is slidably installed inside the filter box 14 through the concave plate 16, the filter plate 15 is easy to disassemble and assemble. A support plate 20 is fixedly installed on the outside of the motor 10, and a base 21 is welded at the lower end of the support plate 20. The support plate 20 and the base 21 provide support for the motor 10, and the reflux pipe 19 passes through the support plate 20 without contacting the pinion 9.

[0025] Working principle: When in use, first inject material into the cylinder 1 through the feeding mechanism 2, start the motor 10 to drive the small gear 9 to rotate through the output shaft, under the meshing action of the small gear 9 and the large gear 8, the large gear 8 drives the cylinder 1 to rotate, and the steel balls inside the cylinder 1 continuously collide with the material to crush the material. Since the straight pipe 201 is connected to the cylinder 1 through a bearing, and the drainage pipe 12 is connected to the cylinder 1 through a bearing, when the cylinder 1 rotates, the feeding mechanism 2 and the drainage pipe 12 remain stationary, which is convenient for feeding and draining. When crushing water-insoluble materials, the first water pump 5 can be started to inject the water inside the water tank 6 into the straight pipe 201 through the water supply pipe 3, and finally flow from the straight pipe 201 into the cylinder 1. After the cylinder 1 is filled with water, it can be discharged to a certain extent. The damage caused by the steel balls to the inner wall of the cylinder 1 is reduced to a certain extent, thereby protecting the inner wall of the cylinder 1 and the inner lining plate 11. As the material is continuously put in, the overflow water in the cylinder 1 is discharged from the drainage pipe 12. Since a flow rate sensor 13 is installed on the drainage pipe 12, the loss rate of the water inside the cylinder 1 is monitored by the flow rate sensor 13. The flow rate sensor 13 transmits the monitoring signal to the controller 7. After analysis, the controller 7 issues an instruction to the flow regulating valve 4, so that the water inlet of the water supply pipe 3 and the water outlet of the drainage pipe 12 are balanced. The overflow water enters the filter box 14 through the drainage pipe 12. The materials carried in the overflow water are insoluble in water and are intercepted by the filter plate 15 and discharged from the discharge pipe 17. The remaining water flows back to the water tank 6 through the second water pump 18 and the return pipe 19 for recycling.
