Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mill technology, and more specifically, to a device that helps prevent material from being discharged from the feed end of a ball mill. Background Technology
[0002] Ball mills can refine solid materials (such as ores, ceramic raw materials, and metal powders) to the micron or even nanometer level, increasing the specific surface area of the materials and improving their reactivity and performance. This function is of great significance in many fields such as materials preparation and mineral processing.
[0003] However, when too much material accumulates inside the ball mill, and the quantity or quality of the grinding media (such as ore) is insufficient to effectively crush this material, the material will gradually accumulate inside the ball mill, causing a "bloating" phenomenon. At this time, the material may be squeezed out from the feed inlet or discharge outlet, manifesting as material discharge from the feed inlet.
[0004] Discharging material from the feed inlet also means that some material is not effectively utilized, resulting in resource waste. This not only increases production costs but may also have a negative impact on the environment. To address these issues, improvements and optimizations to the ball mill's feed end are necessary. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model provides a device that helps prevent material discharge at the feed end of a ball mill, which has the advantage of preventing material discharge at the feed end of the ball mill.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing material discharge from the feeding end of a ball mill, comprising a base plate, a ball mill structure disposed on the middle surface of the base plate, a drive structure disposed on the left side of the base plate, a fixed frame fixedly connected to the upper right surface of the base plate, a feeding bin fixedly connected to the inner side of the fixed frame, a baffle fixedly connected inside the feeding bin, a first movable plate movably connected inside the feeding bin, a first fixed column fixedly connected to the right side surface of the first movable plate, a first motor fixedly connected to the upper surface of the base plate, a fixed disk fixedly connected to the output shaft of the first motor, a second fixed column fixedly connected to the left side surface of the fixed disk, a hinge rod hinged to the surface of the second fixed column, and the hinge rod hinged to the first fixed column.
[0007] As a preferred technical solution of this utility model: the inside of the feeding bin is movably connected to a second movable plate, the upper surface of the bottom plate is fixedly connected to a first base, the upper surface of the first base is fixedly connected to an electric push rod, and the upper part of the electric push rod is fixedly connected to the lower surface of the second movable plate.
[0008] As a preferred technical solution of this utility model: the ball mill structure includes a first support block fixedly connected to the upper surface of the base plate, the ball mill body is rotatably connected inside the first support block, the feed bin is rotatably connected to the right end of the ball mill body, and a toothed ring is fixedly connected to the left side of the ball mill body.
[0009] As a preferred technical solution of this utility model: the driving structure includes a second motor fixedly connected to the upper left surface of the base plate, a second base fixedly connected to the upper surface of the base plate, a reduction motor fixedly connected to the upper surface of the second base, the output shaft of the second motor fixedly connected to the reduction motor, and a gear fixedly sleeved on the output shaft of the reduction motor.
[0010] As a preferred technical solution of this utility model: the output shaft of the geared motor is fixedly connected to a second support block, the second support block is fixedly connected to the upper surface of the base plate, and the gear and the gear ring mesh with each other.
[0011] As a preferred technical solution of this utility model: a screw conveyor assembly is fixedly connected to the left end of the first support block, and the right end of the screw conveyor assembly is rotatably connected to the left side of the ball mill body. The height of the screw conveyor assembly is less than the height of the baffle.
[0012] As a preferred technical solution of this utility model: a guide block is fixedly connected inside the feeding bin, and the guide block is located to the right of the first movable plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by limiting the height of the baffle, ensures that the amount of ore inside the ball mill body is always greater at the right end of the feed port than at the left end of the discharge port, thus allowing the material to be smoothly discharged from the left end of the ball mill body. At the same time, the operation of the first motor drives the first movable plate to move up and down, causing the ore inside the feed bin to exceed the height of the baffle, thereby ensuring that the ore raw material only enters and does not exit, which helps to prevent the phenomenon of material discharge at the feed end of the ball mill, thus facilitating the normal operation of the process.
[0015] 2. This utility model uses an electric push rod to move the second movable plate up and down inside the feeding bin. This allows the second movable plate to block the left side surface of the first movable plate when the first movable plate is feeding material upwards, thus further ensuring that the ore raw material will not be discharged from the feeding end. Compared with traditional devices, which may cause material to be discharged from the feeding end when feeding, this device can further ensure the stability of the ore raw material feeding, thereby preventing the raw material from being discharged and reducing the maintenance cost for workers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5 As shown, this utility model provides a device for preventing material discharge from the feed end of a ball mill, including a base plate 1. A ball mill structure is provided on the middle surface of the base plate 1, a drive structure is provided on the left side of the base plate 1, a fixed frame 2 is fixedly connected to the upper right surface of the base plate 1, a feed bin 3 is fixedly connected to the inner side of the fixed frame 2, a baffle 4 is fixedly connected to the inside of the feed bin 3, a first movable plate 5 is movably connected to the inside of the feed bin 3, a first fixed column 6 is fixedly connected to the right side surface of the first movable plate 5, a first motor 7 is fixedly connected to the upper surface of the base plate 1, a fixed disk 8 is fixedly connected to the output shaft of the first motor 7, a second fixed column 9 is fixedly connected to the left side surface of the fixed disk 8, and a hinge rod 10 is hinged to the surface of the second fixed column 9, the hinge rod 10 and the first fixed column 6 are hinged to each other.
[0024] When it is necessary to refine the ore to the micron or even nanometer level, the operator starts the drive structure to rotate the ball mill body 15. At this time, the first motor 7 is started. Due to the rotation of the output shaft of the first motor 7, the fixed plate 8 is rotated. Since the second fixed column 9 is fixedly connected to the eccentric position of the left side surface of the fixed plate 8, it drives the hinge rod 10 to hinge, thereby driving the first movable plate 5 to move up and down. Since the upper part of the first movable plate 5 is set to an inclined state, when the ore is put in from the upper right of the feed bin 3, it will fall onto the surface of the guide block 23. Since the surface of the guide block 23 is in an inclined state, due to the gravity of the ore, it will slide down to the upper part of the first movable plate 5. The ore slowly rises along the right side surface of the baffle 4. Finally, when the first movable plate 5 is higher than the upper part of the baffle 4, the ore is put into the ball mill body 15.
[0025] The feed hopper 3 is internally connected to a second movable plate 11, and the upper surface of the base plate 1 is fixedly connected to a first base 12. The upper surface of the first base 12 is fixedly connected to an electric push rod 13, and the upper part of the electric push rod 13 is fixedly connected to the lower surface of the second movable plate 11.
[0026] When the first movable plate 5 rises, the electric push rod 13 is controlled by the external control system to work. The output shaft of the electric push rod 13 moves upward, causing the second movable plate 11 to rise and eventually block the left side of the baffle 4. When the first movable plate 5 is higher than the upper surface of the baffle 4, the ore will fall to the upper surface of the baffle 4 due to gravity. When the first movable plate 5 blocks the right side of the baffle 4, the external control system controls the output shaft of the electric push rod 13 to descend, so that the ore raw material enters the ball mill body 15, and then the cycle repeats.
[0027] The ball mill structure includes a first support block 14 fixedly connected to the upper surface of the base plate 1, a ball mill body 15 rotatably connected inside the first support block 14, a feed bin 3 rotatably connected to the right end of the ball mill body 15, and a toothed ring 16 fixedly connected to the left side of the ball mill body 15.
[0028] The first support block 14 provides support to the screw conveyor assembly 22, while the ball mill body 15 refines the ore raw material to the micron or even nanometer level.
[0029] The drive structure includes a second motor 17 fixedly connected to the upper left surface of the base plate 1, a second base 18 fixedly connected to the upper surface of the base plate 1, a reduction motor 19 fixedly connected to the upper surface of the second base 18, the output shaft of the second motor 17 fixedly connected to the reduction motor 19, and a gear 20 fixedly sleeved on the output shaft of the reduction motor 19.
[0030] The operation of the second motor 17 drives the output of the second motor 17 to rotate, thereby driving the reduction motor 19 fixedly installed on the upper surface of the second base 18 to work, and the operation of the reduction motor 19 drives the gear 20 to rotate.
[0031] The output shaft of the geared motor 19 is fixedly connected to a second support block 21, which is fixedly connected to the upper surface of the base plate 1. The gear 20 meshes with the gear ring 16.
[0032] The output shaft of the reduction motor 19 is fixed by the second support block 21 to improve the stability of the device operation. The gear 20 meshes with the gear ring 16, thereby driving the ball mill body 15 to rotate, thus refining the ore raw material located inside the ball mill body 15.
[0033] The first support block 14 has a screw conveyor assembly 22 fixedly connected to the left end, and the right end of the screw conveyor assembly 22 is rotatably connected to the left side of the ball mill body 15. The height of the screw conveyor assembly 22 is less than the height of the baffle 4.
[0034] The auger assembly 22 is fixedly connected to the inside of the first support block 14, while the ball mill body 15 rotates inside the auger assembly 22, thereby realizing the rotation of the ball mill body 15 while the auger assembly 22 remains stationary, thus realizing the material discharge. The outlet height of the auger assembly 22 is lower than the height of the baffle 4 at the feed end, so that the material is discharged from the discharge port due to the height difference.
[0035] The feed hopper 3 is internally fixedly connected to a guide block 23, which is located to the right of the first movable plate 5.
[0036] The inclined design of the guide block 23 allows the material to smoothly reach the top of the first movable plate 5, and thus smoothly be fed into the ball mill body 15.
[0037] Working principle and usage process of this utility model:
[0038] When it is necessary to refine the ore to the micron or even nanometer level, the operator starts the drive structure to rotate the ball mill body 15. At this time, the first motor 7 is started. Due to the rotation of the output shaft of the first motor 7, the fixed plate 8 is rotated. Since the second fixed column 9 is fixedly connected to the eccentric position of the left side surface of the fixed plate 8, it drives the hinge rod 10 to hinge, thereby driving the first movable plate 5 to move up and down. Since the upper part of the first movable plate 5 is set to an inclined state, when the ore is put in from the upper right of the feed bin 3, it will fall onto the surface of the guide block 23. Since the surface of the guide block 23 is in an inclined state, due to the gravity of the ore, it will slide down to the upper part of the first movable plate 5. The ore slowly rises along the right side surface of the baffle 4. Finally, when the first movable plate 5 is higher than the upper part of the baffle 4, the ore is put into the ball mill body 15.
[0039] When the first movable plate 5 rises, the electric push rod 13 is controlled by the external control system to work. The output shaft of the electric push rod 13 moves upward, causing the second movable plate 11 to rise and eventually block the left side of the baffle 4. When the first movable plate 5 is higher than the upper surface of the baffle 4, the ore will fall to the upper surface of the baffle 4 due to gravity. When the first movable plate 5 blocks the right side of the baffle 4, the external control system controls the output shaft of the electric push rod 13 to descend, so that the ore raw material enters the ball mill body 15, and then the cycle repeats.
[0040] The first support block 14 provides support to the screw conveyor assembly 22, while the ball mill body 15 refines the ore raw material to the micron or even nanometer level.
[0041] The operation of the second motor 17 drives the output of the second motor 17 to rotate, thereby driving the reduction motor 19 fixedly installed on the upper surface of the second base 18 to work, and the operation of the reduction motor 19 drives the gear 20 to rotate.
[0042] The output shaft of the reduction motor 19 is fixed by the second support block 21 to improve the stability of the device operation. The gear 20 meshes with the gear ring 16, thereby driving the ball mill body 15 to rotate, thus refining the ore raw material located inside the ball mill body 15.
[0043] The auger assembly 22 is fixedly connected to the inside of the first support block 14, while the ball mill body 15 rotates inside the auger assembly 22, thereby realizing the rotation of the ball mill body 15 while the auger assembly 22 remains stationary, thus realizing the material discharge. The outlet height of the auger assembly 22 is lower than the height of the baffle 4 at the feed end, so that the material is discharged from the discharge port due to the height difference.
[0044] The inclined design of the guide block 23 allows the material to smoothly reach the top of the first movable plate 5, and thus smoothly be fed into the ball mill body 15.
