Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, and more specifically to an automatic dosing device for gear oil of a ball mill. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are crushed. This type of mill is to load a certain number of steel balls into its cylinder as grinding media. The lubrication of the gear transmission of the ball mill equipment is to reduce the wear of the tooth surface and reduce power consumption. The correct selection of lubrication type, viscosity and oil supply method has a great influence on the life of the gear transmission.

[0003] At present, due to the harsh mining environment and the large amount of dust in the air, the oil nozzles are often blocked by mineral powder, resulting in poor lubrication of the transmission gears during the operation of the ball mill, causing pitting, wear and even broken teeth on the tooth surfaces, and time-consuming and laborious maintenance.

[0004] After searching, a Chinese patent with authorization announcement number CN202170985U discloses a ball mill transmission gear oiling device. The lubricating oil is directly injected into the oil hopper and the valve is loosened. The lubricating oil flows into the oil spreading pipe through the oil downpipe under the action of gravity. The lubricating oil drips into the gear through the oil hole on the oil spreading pipe to complete the lubrication, eliminate the phenomenon of poor lubrication of the transmission gear, and extend the service life of the transmission gear. In addition, the lubricating oil flow rate is accurately controlled by the valve to find an optimal flow rate, which can not only ensure sufficient lubrication of the gear, but also save lubricating oil and make full use of it without waste.

[0005] However, when the structure is actually used, the staff is required to pour lubricating oil into the oil hopper each time it is used, and the metering of the added lubricating oil depends entirely on manual control of the valve, which is time-consuming and labor-intensive, and easily leads to waste or incomplete lubrication.

[0027] Working principle of this utility model:

[0028] The utility model patent mainly designs an automatic dosing device for ball mill gear oil. When the device is in use, during the working process, the starting motor 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the small gear 10 to rotate, and the small gear 10 is meshed with the large gear 14, so that the small gear 10 drives the large gear 14 to rotate, and then drives the ball mill to rotate;

[0029] Then, the feed pipe 20 is connected to the external oil delivery pipe, and then the butterfly valve 21 is opened to start the electric telescopic rod 4, which drives the piston 3 to move to the side away from the feed pipe 20, so that the external lubricating oil enters the interior of the storage tank 1 through the feed pipe 20. Since the surface of the storage tank 1 is set to be transparent, the liquid measurement inside the storage tank 1 can be visually observed. After it is full, the butterfly valve 21 is closed, and then the solenoid valve on one side of the oil delivery pipe 5 is opened, and then the electric telescopic rod 4 is started to drive the piston 3 to move to the side close to the feed pipe 20, so that the lubricating oil inside the storage tank 1 is delivered to the nozzle 6 through the oil delivery pipe 5 and sprayed, thereby spraying to the connection between the pinion 10 and the first dust cover 11, that is, the lubricating oil is mixed with the compressed air and sprayed in a mist. Since the pinion 10 drives the large gear 14 to rotate, the lubricating oil is more evenly covered on the pinion 10 and the large gear 14;

[0030] At the same time, the first dust cover 11, the second dust cover 12 and the protective cover 7 are used to effectively prevent dust from entering. At the same time, the lubricating oil remaining on the surface of the small gear 10 and the large gear 14 after the spraying is completed enters the bottom of the connecting pipe 16 and enters the collecting box 15 for collection. Then, by starting the oil pump 17, the remaining lubricating oil enters the inside of the storage tank 1 again through the L-shaped pipe 18, and then is recycled to prevent waste.

[0031] After a period of use, when the lubricating oil inside the storage tank 1 is consumed to the bottom of the storage tank 1, the oil level sensor 2 senses the oil level and transmits a signal to the external controller, which closes the solenoid valve of the oil pipeline 5, opens the butterfly valve 21, starts the electric telescopic rod 4, and drives the piston 3 to move, thereby automatically adding material, saving time and effort.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
