[0001] This utility model belongs to the field of ball mill technology, and in particular relates to a dust removal structure for the inner cylinder of a ball mill. Background Technology

[0002] Ball mills are important crushing equipment widely used in many industries. They are mainly composed of a cylinder, grinding media, transmission device, and lubrication system. The grinding media impact, grind, and squeeze the material inside the rotating cylinder to achieve material crushing and refinement. The cylinder is the core component, with wear-resistant liners on the inner wall and end caps, as well as feed and discharge ports at both ends. The grinding media include steel balls and steel rods, the size and quantity of which depend on the specifications of the ball mill and the properties of the material. The transmission device consists of a motor, reducer, and coupling to drive the cylinder to rotate. The lubrication system lubricates all moving parts to reduce wear and friction and extend the service life of the equipment.

[0003] The feed end of the ball mill inner cylinder is relatively small. Traditional dust removal of the inner cylinder usually requires workers to use long tools to scrape off the dust bit by bit. This cleaning method is troublesome and time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal structure for the inner cylinder of a ball mill, which has the advantage of automatic dust removal, in order to solve the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dust removal structure for the inner cylinder of a ball mill includes a bottom plate, a rotating component and a protective shell. The rotating component is movably connected to the inside of the bottom plate. A dust removal component is provided on the surface of the rotating component. The protective shell is detachably connected to the surface of the dust removal component. The rotating component is used to drive the dust removal component to run. The dust removal component is used to automatically scrape the dust off the inner wall of the inner cylinder.

[0006] Preferably, the rotating assembly includes a movable wheel, a second gear, and a motor. The movable wheel is movably connected to the inside of the base plate, and the second gear is fixedly connected to one side of the surface of the movable wheel.

[0007] Preferably, the motor is fixedly connected to one side of the base plate surface, and a first gear is fixedly connected to the output end of the motor, with the first gear and the second gear in a transmission engagement.

[0008] Preferably, the dust removal assembly includes a bottom shell, a mounting block, a pull plate, and a fixed shell. All four bottom shells are fixedly connected to one side of the surface of the movable wheel, and all four bottom shells are movably connected to a limit rod.

[0009] Preferably, a dust removal plate is fixedly connected to the surface of each of the four sets of limiting rods, an electric push rod is fixedly connected to the middle of one side of the surface of the movable wheel, and the mounting block is fixedly connected to the piston end of the electric push rod.

[0010] Preferably, four sets of rotating rods are fixedly connected inside the mounting block, and the four sets of pull plates are movably connected to the surfaces of the four sets of rotating rods respectively.

[0011] Preferably, each of the four sets of pull plates has a rotating column movably connected to one end of its surface, the four sets of fixed shells are respectively fixedly connected to the surfaces of the four rotating columns, and the four sets of fixed shells are respectively fixedly connected to one side of the surfaces of the four sets of dust removal plates.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model allows for appropriate adjustment of the spacing between the four sets of dust removal plates through the dust removal component, making it suitable for inner cylinders with smaller diameters. When the dust removal component is in the appropriate position, the rotating component can drive the dust removal component to rotate, thus scraping away the dust on the inner wall of the inner cylinder. This achieves the purpose of improving the practicality of the dust removal device and the cleaning efficiency of the inner cylinder.

[0014] 2. When the motor is running, it drives the first gear to rotate. The first gear rotates with the second gear it meshes with, which in turn drives the movable wheel to rotate inside the base plate, thus providing power for cleaning the inner wall of the inner cylinder.

[0015] 3. When the electric push rod is running, it will drive the mounting block to move up and down. When it retracts to one side, the pull plate will pull the dust removal plate to one side inside the bottom shell by means of the limit rod while the rotating rod moves on the rotating column surface. This can reduce the distance between the four sets of dust removal plates, making it easier to set the four sets of dust removal plates inside the inner cylinder. Conversely, it can increase the distance, which can facilitate the cleaning of the inner wall of the inner cylinder and improve the efficiency of automatic cleaning. Attached Figure Description

[0022] In the following description, embodiments of the dust removal structure for the inner cylinder of a ball mill according to the present invention will be described with reference to the accompanying drawings.

[0023] Example 1:

[0024] Figure 1-3 This invention illustrates a dust removal structure for the inner cylinder of a ball mill, comprising a base plate 1, a rotating assembly 2, and a protective shell 4. The rotating assembly 2 is movably connected to the inside of the base plate 1, and a dust removal assembly 3 is disposed on the surface of the rotating assembly 2. The protective shell 4 is detachably connected to the surface of the dust removal assembly 3. The rotating assembly 2 is used to drive the dust removal assembly 3 to operate, and the dust removal assembly 3 is used to automatically scrape away dust from the inner wall of the inner cylinder.

[0025] By adopting the above scheme, the dust removal component 3 can appropriately adjust the spacing between the four sets of dust removal plates 303, which can be applied to inner cylinders with smaller diameters. When the dust removal component 3 is in a suitable position, the rotating component 2 can drive the dust removal component 3 to rotate, so that the dust removal component 3 can scrape off the dust on the inner wall of the inner cylinder, thereby improving the practicality of the dust removal device and the cleaning efficiency of the inner cylinder.

[0026] Example 2:

[0027] refer to Figure 1 The rotating assembly 2 includes a movable wheel 204, a second gear 203, and a motor 201. The movable wheel 204 is movably connected to the inside of the base plate 1, and the second gear 203 is fixedly connected to one side of the surface of the movable wheel 204. The motor 201 is fixedly connected to one side of the surface of the base plate 1, and the output end of the motor 201 is fixedly connected to a first gear 202. The first gear 202 and the second gear 203 are in a transmission engagement.

[0028] The above solution is adopted: when the motor 201 is running, it will drive the first gear 202 to rotate. The first gear 202 will rotate with the second gear 203 that meshes with it, which in turn will drive the movable wheel 204 to rotate inside the base plate 1, thus achieving the effect of providing power for cleaning the inner wall of the inner cylinder.

[0029] Example 3:

[0030] refer to Figure 2 and Figure 3The dust removal assembly 3 includes a base shell 301, a mounting block 305, a pull plate 307, and a fixed shell 308. Four sets of base shells 301 are fixedly connected to one side of the surface of the movable wheel 204. Limiting rods 302 are movably connected inside each of the four sets of base shells 301. Dust removal plates 303 are fixedly connected to the surfaces of the four sets of limiting rods 302. An electric push rod 304 is fixedly connected to the middle of one side of the surface of the movable wheel 204. The mounting block 305 is fixedly connected to the piston end of the electric push rod 304. Four sets of rotating rods 306 are fixedly connected inside the mounting block 305. Four sets of pull plates 307 are movably connected to the surfaces of the four sets of rotating rods 306. A rotating column 309 is movably connected to one end of the surface of each of the four sets of pull plates 307. Four sets of fixed shells 308 are fixedly connected to the surfaces of the four sets of rotating columns 309. The four sets of fixed shells 308 are also fixedly connected to one side of the surface of each of the four sets of dust removal plates 303.

[0031] The above solution is adopted: when the electric push rod 304 is running, it will drive the mounting block 305 to move up and down. When it retracts to one side, the pull plate 307 will pull the dust removal plate 303 to one side inside the bottom shell 301 by means of the limiting rod 302, while the rotating rod 306 moves on the surface of the rotating column 309. This can reduce the distance between the four sets of dust removal plates 303, making it easier to set the four sets of dust removal plates 303 inside the inner cylinder. Conversely, it can increase the distance, which can facilitate the cleaning of the inner wall of the inner cylinder and improve the efficiency of automatic cleaning.

[0032] Working principle: When this utility model is in use, the user will drive the first gear 202 to rotate when the motor 201 is running. The first gear 202 will rotate with the meshing second gear 203, which in turn will drive the movable wheel 204 to rotate inside the base plate 1. When the electric push rod 304 is running, it will drive the mounting block 305 to move up and down. When it retracts to one side, the pull plate 307 will pull the dust removal plate 303 to one side inside the bottom shell 301 by means of the limiting rod 302, while the rotating rod 306 moves on the surface of the rotating column 309. This reduces the distance between the four sets of dust removal plates 303, making it easier to set the four sets of dust removal plates 303 inside the inner cylinder. Conversely, the distance will be increased.

[0033] In summary, the dust removal structure of the ball mill inner cylinder can drive the dust removal component 3 to rotate by the rotating component 2. In this way, the dust removal component 3 can scrape off the dust on the inner wall of the inner cylinder, thereby improving the practicality of the dust removal device and the cleaning efficiency of the inner cylinder.
