Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically a ball mill for noise reduction in cement preparation. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. They are mainly used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics. Ball mills can be divided into two types according to the discharge method: grate type and overflow type. They can also be divided into two grinding methods: dry and wet. They are suitable for grinding various ores and other materials and are widely used in mineral beneficiation, building materials and chemical industries.

[0003] In existing ball mills, the large gear outside the ball mill cylinder is driven by gears during operation. However, the large gear outside the ball mill cylinder is exposed and is prone to dust and impurities falling on it. When the gears mesh, it will cause gear wear, generate noise, and affect the service life of the gears. Therefore, this application proposes a ball mill with noise reduction function for cement preparation. Utility Model Content

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] This utility model provides a ball mill for noise reduction in cement preparation. The bottom of the external gear is immersed in the oil tank, and it comes into contact with the lubricating oil for lubrication while rotating. Simultaneously, a cleaning roller driven by the gear cleans the external gear, preventing impurities from getting into the ball mill drive gear and causing wear. This protects the gear, reduces noise from gear wear, and extends the gear's service life. Please refer to [link to relevant documentation]. Figures 1-4 It includes: ball milling mechanism 100, drive mechanism 200 and cleaning box 300.

[0030] The ball mill mechanism 100 includes a base 110, a bracket 120, a ball mill cylinder 130, and an external gear 140. The top of the base 110 is connected to the ball mill cylinder 130 through the bracket 120. The external gear 140 is provided on the outer wall of the ball mill cylinder 130. Cement material is placed inside the ball mill cylinder 130 for grinding.

[0031] The drive mechanism 200 is connected to the external gear 140. The drive mechanism 200 includes a drive component 210, a ball mill drive gear 220 and a cleaning drive gear 230. The ball mill drive gear 220 that meshes with the external gear 140 is provided on the output end of the drive component 210, and the cleaning drive gear 230 is provided at the end of the output end of the drive component 210.

[0032] The drive component 210 includes a drive motor and a gearbox. The input end of the gearbox is connected to the drive motor, and the output end of the gearbox is connected to the ball mill drive gear 220 and the cleaning drive gear 230. The drive component 210 drives the ball mill drive gear 220 to rotate. The ball mill drive gear 220 meshes and drives the external gear 140 to rotate. The external gear 140 synchronously drives the ball mill cylinder 130 to rotate for processing.

[0033] The cleaning box 300 is disposed between the external gear 140 and the ball mill drive gear 220. The cleaning box 300 includes an oil tank 310, a rotating shaft 320, a transmission gear 330 and a cleaning roller 340. The rotating shaft 320 is disposed on both sides of the inner cavity of the oil tank 310. One end of the rotating shaft 320 is provided with a transmission gear 330 that meshes with the cleaning drive gear 230, and the other end of the rotating shaft 320 is provided with a cleaning roller 340 that contacts the external gear 140.

[0034] The oil tank 310 has a shaft hole on its side. A sealing gasket is provided between the output shaft of the drive component 210 and the shaft hole. The drive component 210 drives the cleaning drive gear 230 to rotate. The cleaning drive gear 230 drives the transmission gear 330 to rotate. The transmission gear 330 drives the cleaning roller 340 to rotate through the rotating shaft 320. The cleaning roller 340 cleans the external gear 140.

[0035] To prevent impurities from falling into the fuel tank 310, a protective cover 400 is provided at the top opening of the fuel tank 310. The protective cover 400 is a sponge cover located between the fuel tank 310 and the external gear 140, and the protective cover 400 is used to seal and protect the gaps in the fuel tank 310.

[0036] Since the bottom of the external gear 140 needs to be in contact with the lubricating oil, the bottom of the external gear 140 passes through the protective cover 400 and enters the oil tank 310, so that the bottom of the external gear 140 is immersed in the lubricating oil in the oil tank 310.

[0037] Since it is necessary to clean the gaps between the teeth of the gear, the cleaning roller 340 is a soft-bristled roller brush. The bristles of the cleaning roller 340 contact the external gear 140 to effectively clean the gear.

[0038] As impurities gradually accumulate in the oil tank 310, the lubricating oil needs to be replaced in a timely manner. Therefore, a drain pipe is installed at the bottom of the side wall of the oil tank 310, and a sealing plug is installed at the end of the drain pipe. The sealed plug is pulled out, and the deposited lubricating oil is drained through the drain pipe for replacement.

[0039] In practical use, the drive component 210 drives the ball mill drive gear 220 to rotate, which in turn drives the external gear 140 to rotate. The external gear 140 synchronously drives the ball mill cylinder 130 to rotate for processing. While the external gear 140 is rotating, its bottom is immersed in the oil tank 310 for lubrication. At the same time, the drive component 210 drives the cleaning drive gear 230 to rotate, which in turn drives the transmission gear 330 to rotate. The transmission gear 330 drives the cleaning roller 340 to rotate via the rotating shaft 320. The cleaning roller 340 cleans the external gear 140, preventing impurities from getting mixed between the external gear 140 and the ball mill drive gear 220, which would cause gear wear. This protects the gear, reduces noise caused by gear wear, and improves the service life of the gear.

[0040] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
