Description

Technical Field

[0001] The utility model relates to a steel ball cleaning device in a tower mill cylinder. The tower mill is a mill mainly used for grinding gold concentrate. Background Art

[0002] Currently, the crushing equipment used in grinding operations in the mineral processing industry primarily includes tower mills and rod mills. Tower mills, as a crucial core piece of equipment for regrinding gold concentrate, play a crucial role in the gold smelting process, both in terms of their operation and maintenance. During tower mill operation, the grinding media, steel balls, further grind the ore slurry to the required fineness through mutual friction. After prolonged mutual compression, some steel balls become firmly attached to the grating lining of the tower mill and accumulate at the bottom of the mill. When inspecting and replacing the spiral lining and grate lining of the tower mill, the steel balls at the bottom of the mill and those adhering to the grate must be cleaned to facilitate replacement of the spiral lining and grate.

[0003] Since there is currently no simple and practical device for cleaning steel balls from the tower mill barrel, the industry's commonly used method for cleaning steel balls is to use manual tools such as sledgehammers, crowbars, and shovels to clean the steel balls attached to the grating plates of the tower mill's lining. Due to the large number of steel balls attached to the grating plates in the tower mill barrel and the large number of steel balls accumulated at the bottom of the tower mill, the cleaning operation environment is relatively harsh, which is not only labor-intensive and inefficient, but also difficult to ensure safety. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a steel ball cleaning device inside the tower mill cylinder, which can clean the steel balls attached to the bottom of the tower mill and the grating plate through mechanical operation, reduce the intensity of cleaning operations, improve cleaning efficiency, and reduce safety hazards.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A device for cleaning steel balls in a tower mill cylinder comprises an actuator and a driving mechanism connected to each other, the actuator comprising a side plate, the front side of the side plate being fixedly connected to a mounting plate, a support plate being connected between the front side of the side plate and the lower side of the mounting plate; a scraper being connected to the upper side of the mounting plate; an upper and lower connecting plate being fixedly connected to the rear side of the side plate, the upper and lower connecting plates being arranged parallel to each other and perpendicular to the side plates, a connecting shaft being installed between the two connecting plates, the connecting shafts being arranged parallel to each other and perpendicular to the connecting plates, and the connecting shafts being used to connect to the driving mechanism.

[0007] Preferably, the scraper includes a flat plate section and an arc section that are integrated with each other; the flat plate section is fixedly connected to the mounting plate, the arc section is bent upward, and the arc section is provided with a blade; the blade is located on the left and right sides of the arc section; the arc section is located in front of the mounting plate and the support plate.

[0008] Preferably, the driving mechanism includes a rotating shaft for driving the actuator to rotate horizontally; the upper end of the rotating shaft is fixedly connected to the turntable, and the lower end is rotatably connected to the turntable; the driving mechanism also includes a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod; the rear end of the first connecting rod is hinged to the turntable, and a first oil cylinder is connected between the middle part of the first connecting rod and the turntable, and the front end of the first connecting rod is hinged to the middle part of the second connecting rod; a second oil cylinder is connected between the rear end of the second connecting rod and the first connecting rod, and the front end of the second connecting rod is connected to one of the connecting shafts; one end of the third connecting rod is hinged to the second connecting rod, and the other end is hinged to the rear end of the fourth connecting rod; the front end of the fourth connecting rod is connected to another connecting shaft; a third oil cylinder is connected between the second connecting rod and the third connecting rod.

[0009] Further preferably, a motor, a small gear driven by the motor, and a large gear meshing with the small gear are mounted on the rotary support, and the large gear is connected to the rotary shaft.

[0010] The positive effects of this utility model are:

[0011] The motor of the driving mechanism drives the rotating shaft and the turntable to rotate synchronously through a gear mechanism, thereby driving the actuator to rotate horizontally. When the first cylinder is working, it drives the first connecting rod to rotate around the rear end of the first connecting rod. When the second cylinder is working, it drives the second connecting rod to rotate around the hinge position between the first and second connecting rods. When the third cylinder is working, it drives the actuator to rotate around one of the connecting shafts. The above three cylinders work together to realize the lifting, pitching and hooking movements of the actuator. The steel balls attached to the lining grating of the tower mill and accumulated in the tower mill are scraped and sent to the steel ball collection bucket in the pit outside the tower mill cylinder, thereby achieving the purpose of cleaning the steel balls in the tower mill cylinder. This device effectively improves the cleaning efficiency of the steel balls in the tower mill cylinder, reduces the labor intensity of the operators, and increases the safety of the operation.
