Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and in particular to an adjustable speed vertical coal gangue grinding mill. Background Technology

[0002] Currently, vertical grinding mills for coal gangue suffer from several problems when processing coal gangue, including fixed rotation speeds that are difficult to adapt to different material characteristics, poor grinding effects, and inconvenient maintenance. Traditional grinding mills cannot adjust their rotation speed according to the hardness and moisture content of the coal gangue, which easily leads to low grinding efficiency and high energy consumption. Furthermore, the grinding rollers and other components require complete disassembly for maintenance, resulting in high costs and long processing times. Improvements are urgently needed.

[0003] While existing technologies can achieve a certain grinding effect during use, they have drawbacks: they lack sufficient grinding capacity and independent drive for precise maintenance. In view of this, we propose an adjustable-speed vertical coal gangue grinding mill to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an adjustable-speed vertical coal gangue grinding mill.

[0005] The technical solution of this utility model is as follows: an adjustable speed vertical coal gangue grinding mill, including a shell and a mounting platform. The outer side of the shell is provided with two sets of mounting platforms arranged in a circular array. One set of mounting platforms is fixedly connected to a first mounting plate. A first rotating motor is fixedly connected to one side of the first mounting plate. The output shaft of the first rotating motor is fixedly connected to the rotation center of a first connecting rod. One end of the first connecting rod is fixedly connected to a first grinding roller.

[0006] When using one of the adjustable-speed vertical coal gangue grinding mills in this solution, the fourth rotary motor is driven to rotate the connecting column. The rotation of the connecting column drives the grinding disc to rotate, feeding coal gangue into the casing through the feed inlet. The coal gangue falls to the central area of ​​the grinding disc due to inertia. The second motor is then driven to rotate the second connecting rod, which in turn drives the second grinding roller to rotate. The second grinding roller grinds the coal gangue near the center of the grinding disc. Due to the centrifugal force acting on the grinding disc, smaller pieces of coal gangue move faster to the edge of the grinding disc, driving the first rotary motor to rotate the first connecting rod. The rotation of the first connecting rod drives the first grinding roller. The first grinding roller rotates to grind the coal gangue in the edge area of ​​the grinding disc. The addition of the first grinding roller can increase the grinding area and grinding efficiency. During maintenance, since each grinding roller is driven independently by a single corresponding motor, precise maintenance can be carried out according to the faulty grinding roller. The hot air blower continuously blows out strong hot air. The hot air blows the coal gangue powder on the edge of the grinding disc upward through the through groove. The third motor drives the rotating rod to rotate. The rotating rod drives the screen to rotate. The rotating screen can knock the large coal gangue particles that are not fully ground back to the grinding disc for re-grinding. Coal gangue powder of different sizes enters the screen and is finally blown out from the discharge port by the wind force.

[0007] Preferably, another set of mounting platforms is fixedly connected to a second mounting plate, a second rotating motor is fixedly connected to one side of the second mounting plate, the output shaft of the second rotating motor is fixedly connected to the rotation center of the second connecting rod, and one end of the second connecting rod is fixedly connected to the second grinding roller.

[0008] Preferably, a fourth rotating motor is fixedly connected to the inner wall of the lower end of the housing, the output shaft of the fourth rotating motor is fixedly connected to the rotation center of the connecting column, and the upper end of the connecting column is fixedly connected to the outer wall of the grinding disc.

[0009] Preferably, the inner wall of the housing is provided with a through groove, and a hot air blower is provided on the inner wall of the lower end of the housing.

[0010] Preferably, a third rotating motor is fixedly connected to the upper outer wall of the housing, the output shaft of the third rotating motor is fixedly connected to the rotation center of the rotating rod, and the lower outer wall of the rotating rod is fixedly connected to the screen.

[0011] Preferably, the upper end of the shell is provided with a discharge port, which is located above the screen, and the shell is provided with a feed port.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. In this utility model, the first and second grinding rollers are symmetrically distributed around the circumference, respectively responsible for grinding the center and edge areas of the grinding disc, thus increasing the grinding range. The cross-section of the grinding rollers is trapezoidal, with the inclined side parallel to the grinding disc, ensuring uniform grinding and a large grinding area. Combined with an adjustable speed motor, it can be flexibly adjusted according to the material characteristics to fully grind coal gangue.

[0014] Second, based on the first beneficial effect, each grinding roller is driven by an independent motor, which allows for rapid location of the faulty roller in case of a malfunction. There is no need for large-scale disassembly of the entire system; only the motor and related components corresponding to the faulty roller need to be inspected, greatly shortening maintenance time and reducing maintenance costs.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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.

[0027] Example 1

[0028] Please see Figures 1-5 As shown, this embodiment is an adjustable-speed vertical coal gangue grinding mill, including a housing 4 and a mounting platform 8. Multiple sets of mounting platforms 8 arranged in a circular array are provided on the outer side of the housing 4. One set of mounting platforms 8 is fixedly connected to a first mounting plate 3. A first rotating motor 2 is fixedly connected to one side of the first mounting plate 3. The output shaft of the first rotating motor 2 is fixedly connected to the rotation center of the first connecting rod 12. One end of the first connecting rod 12 is fixedly connected to the first grinding roller 17. In use, the first motor and the second motor are adjustable-speed motors. The cross-sections of the first grinding roller 17 and the second grinding roller 15 are both trapezoidal, with the hypotenuse of the trapezoid close to and parallel to the grinding disc 13. This design ensures a uniform grinding effect and a large grinding area when the grinding rollers rotate. Driving the first rotating motor 2 causes the first connecting rod 12 to rotate, and the rotation of the first connecting rod 12 drives the first grinding roller 17 to rotate.

[0029] Example 2

[0030] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: another set of mounting platforms 8 fixedly connected to a second mounting plate 5, a second rotating motor 6 fixedly connected to one side of the second mounting plate 5, the output shaft of the second rotating motor 6 fixedly connected to the rotation center of the second connecting rod 14, and one end of the second connecting rod 14 fixedly connected to the second grinding roller 15. In use, the second grinding roller 15 and the first grinding roller 17 are circumferentially symmetrically distributed within the housing 4 to ensure the uniformity of grinding the coal gangue on the grinding disc 13. Driving the second rotating motor 6 can cause the second connecting rod 14 to rotate, and the rotation of the second connecting rod 14 can drive the second grinding roller 15 to rotate.

[0031] A fourth rotary motor 19 is fixedly connected to the inner wall of the lower end of the housing 4. The output shaft of the fourth rotary motor 19 is fixedly connected to the rotation center of the connecting column 20. The upper end of the connecting column 20 is fixedly connected to the outer wall of the grinding disc 13. In use, driving the fourth rotary motor 19 can make the connecting column 20 rotate. The rotation of the connecting column 20 can drive the grinding disc 13 to rotate, thereby driving the coal gangue on the grinding disc 13 to make circular motion, so that the coal gangue can be fully ground and the coal gangue powder can move through the groove 16.

[0032] The inner wall of the shell 4 is provided with a through groove 16, and the lower inner wall of the shell 4 is provided with a hot air blower 18. When in use, the hot air blower 18 can heat and blow out air to meet the wind force required for the coal gangue powder to be lifted, and at the same time, it can dry the coal gangue powder.

[0033] A third rotating motor 11 is fixedly connected to the upper outer wall of the housing 4. The output shaft of the third rotating motor 11 is fixedly connected to the rotation center of the rotating rod 9. The lower outer wall of the rotating rod 9 is fixedly connected to the screen 10. In use, the third rotating motor 11 is driven to rotate the rotating rod 9. The rotation of the rotating rod 9 can drive the screen 10 to rotate. The rotating screen 10 can knock down large-volume coal gangue and prevent coal gangue from accumulating on the screen 10.

[0034] The upper end of the shell 4 is provided with a discharge port 1, which is located above the screen 10. The shell 4 is provided with a feed port 7, which enters the interior of the shell 4 from the outer wall of the shell 4. The feed port 7 is inclined inside the shell 4, so that the coal gangue can fall close to the center area of ​​the grinding disc 13 due to inertia.

[0035] Instructions for use: When using this device, drive the fourth rotary motor 19 to rotate the connecting column 20. The rotation of the connecting column 20 drives the grinding disc 13 to rotate, allowing coal gangue to be fed into the housing 4 through the feed inlet 7. The coal gangue falls to the central area of ​​the grinding disc 13 due to inertia. Drive the second motor to rotate the second connecting rod 14, which in turn drives the second grinding roller 15 to rotate. The second grinding roller 15 grinds the coal gangue near the center of the grinding disc 13. Due to the centrifugal force acting on the grinding disc 13, smaller pieces of coal gangue will move to the edge of the grinding disc 13 more quickly. Drive the first rotary motor 2 to rotate the first connecting rod 12, which in turn drives the first grinding roller 15 to rotate. 7. Rotation of the first grinding roller 17 allows for grinding of the coal gangue in the edge area of ​​the grinding disc 13. The addition of the first grinding roller 17 increases the grinding area and grinding efficiency. During maintenance, since each grinding roller is driven independently by a single corresponding motor, precise maintenance can be performed based on the faulty grinding roller. The hot air blower 18 continuously blows out strong hot air, which blows the coal gangue powder on the edge of the grinding disc 13 upward through the through slot 16. The third motor drives the rotating rod 9 to rotate, which in turn drives the screen 10 to rotate. The rotating screen 10 can knock large, insufficiently ground coal gangue particles back to the grinding disc 13 for re-grinding. Coal gangue powder of various sizes enters the screen 10 and is finally blown out from the discharge port 1 by the wind force.
