Description

Technical Field

[0001] This invention belongs to the field of ball mill technology, specifically relating to a ball mill partition plate with adjustable grate hole gap. Background Technology

[0002] The baffle plates in a ball mill function to separate the grinding media. As the particle size gradually decreases towards the mill tail, the grinding media initially exert a predominantly impacting action, transitioning to a predominantly grinding action towards the tail. Therefore, the size of the grinding media decreases sequentially from the mill head to the mill tail. Adding baffle plates separates grinding media of different sizes, preventing cross-contamination. The baffle plates also prevent large particles from entering the finer grinding chambers, acting as a screen to prevent excessively large particles from entering. Otherwise, the accumulation of uncrushed particles would severely affect the grinding efficiency. The baffle plates also control the material flow rate. The size and opening ratio of the grate holes on the baffle plates determine the flow rate of the grinding material, thus affecting the grinding time. Currently, the size and opening ratio of the grate holes in existing ball mills are fixed, making it impossible to meet the different fine grinding standards and requirements of materials in actual ball milling processes. Therefore, it is essential to study a ball mill diaphragm plate with adjustable grate holes. Summary of the Invention

[0036] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative effort.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0038] Combination Figures 1-8 As shown, the present invention provides a ball mill partition plate with adjustable grate hole gap, comprising a plate body 1, a connecting cylinder 3, an adjusting plate 4, an adjusting device 5, and a driving device 6.

[0039] According to one embodiment of the present invention, the plate body 1 is a circular plate structure surrounded by multiple fan-shaped grate plates 11. Multiple grate holes 2 are provided on the fan-shaped grate plates 11, and the size of the grate holes 2 determines the size of the material to be milled. The adjustable grate gap ball mill partition plate of the present invention also has a connecting cylinder 3 fixedly connected to the middle of one side of the plate body 1. When the adjustable grate hole gap ball mill partition plate of the present invention is assembled onto the ball mill, it rotates with the rotation of the ball mill, and the connecting cylinder 3 moves accordingly. The connecting cylinder 3 is provided with ventilation holes 32.

[0040] In this embodiment, the adjusting plate 4 is a disc structure with a through hole in its center. The adjusting plate 4 is sleeved on the connecting cylinder 3 through the through hole. The connecting cylinder 3 rotates with the ball mill, realizing the relative rotation between the adjusting plate 4 and the connecting cylinder 3. Furthermore, the adjusting plate 4 can move axially along the connecting cylinder 3. According to one embodiment of the present invention, the adjusting device 5 is located between the adjusting plate 4 and the plate body 1, such as... Figure 1 As shown, the adjusting device 5 is located below the adjusting plate 4 and includes a fixing plate 51 and a blocking plate 52. In this embodiment, the fixing plate 51 has a disc structure and is detachably fixed to the adjusting plate 4. Multiple blocking plates 52 are provided, arranged circumferentially along the fixing plate 51, and the blocking plates 52 are hinged to the fixing plate 51.

[0041] The ball mill partition plate with adjustable grate hole gap of the present invention is further provided with a driving device 6. In this embodiment, the driving device 6 is connected to the adjusting plate 4 and is used to drive the adjusting plate 4 to move circumferentially along the connecting cylinder 3 so that the blocking plate 52 moves to block the grate hole 2, thereby achieving the purpose of adjustable grate hole 2 gap.

[0042] The adjustable grate hole gap ball mill partition plate of the present invention allows for finer grinding when a finer grinding is required. The adjusting plate 4 can be driven by the driving device 6 to move along the circumference of the connecting cylinder 3 towards the plate body 1. Due to the detachable fixed connection between the fixed plate 51 and the adjusting plate 4, and the hinged connection between the baffle plate 52 and the fixed plate 51, the fixed plate 51 and the baffle plate 52 move simultaneously with the adjusting plate 4. When the baffle plate 52 moves to its lower end and contacts the plate body 1, the hinged connection between the baffle plate 52 and the fixed plate 51 causes the fixed plate 51 to continue moving downwards, causing the baffle plate 52 to spread outwards, thus blocking the grate hole 2 and reducing the size of the passage portion to achieve finer grinding of the material. The rotational setting of the adjusting plate 4 and the connecting cylinder 3 allows for adjustment of the degree of blocking of the grate hole by the baffle plate 52, thereby achieving different sizes of the grate hole 2.

[0043] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the shielding plate 52 and the fixing plate 51 are inclined. Specifically, the distance between the shielding plate 52 and the connecting cylinder 3 gradually increases along the direction close to the plate body 1. This arrangement facilitates the shielding plate 52 to spread outward when it moves towards and contacts the plate body 1.

[0044] In this embodiment, multiple grate holes 2 are arranged at equal angular intervals along the circumference of the plate body 1, and multiple baffle plates 52 are arranged at equal angular intervals along the circumference of the fixing plate 51. The angular interval between adjacent baffle plates 52 is the same as the angular interval between adjacent grate holes 2. The width of the baffle plate 52 is equal to the width of the grate hole 2. In addition, the adjusting plate 4 of the present invention is provided with an angle scale line 43, and the connecting cylinder 3 is provided with a reference scale line 31.

[0045] The adjustable grate hole gap ball mill partition plate of the present invention, the above-mentioned relative arrangement of the baffle plate 52 and the grate hole 2, can realize the angular offset between the baffle plate 52 and the grate hole 2 by adjusting the relative rotation of the plate 4 and the connecting cylinder 3. By different rotation angles, different degrees of occlusion of the grate hole 2 by the baffle plate 52 can be realized, thereby realizing the adjustment of different gaps of the grate hole 2.

[0046] Combination Figures 5-8As shown, according to one embodiment of the present invention, the adjusting plate 4 of the present invention is provided with an installation groove 41, the installation groove 41 is annular, and a limiting groove 42 is provided on the outer circumferential side of the installation groove 41; the fixing plate 51 is located in the installation groove 41 and is detachably fixedly connected to the fixing plate 51 by bolts, and the limiting groove 42 corresponds to the shielding plate 52.

[0047] According to one embodiment of the present invention, the fixing plate 51 is provided with a threaded through hole, and the adjusting plate 4 is provided with a threaded hole corresponding to the threaded through hole. The fixing plate 51 is fixedly connected to the adjusting plate 4 by means of a screw passing through the threaded through hole on the fixing plate 51, thereby realizing the detachable connection between the fixing plate 51 and the adjusting plate 4.

[0048] The adjustable grate hole gap ball mill partition plate of the present invention, through the above-described structure, after the shielding plate 52 spreads outward from the inside of the plate body 1, the limiting groove 42 can fix and limit the spread shielding plate 52, thereby effectively improving the shielding effect of the shielding plate 52 on the grate hole 2, preventing the shielding plate 52 from shifting during the grinding process, thus helping to improve the grinding quality.

[0049] Furthermore, according to one embodiment of the present invention, the baffle plate 52 is hinged to the fixed plate 51 with a rotation range of 10°-170°. The side of the baffle plate 52 facing the connecting cylinder 3 is flat. The side of the baffle plate 52 facing away from the connecting cylinder 3 is provided with a brush structure.

[0050] In this embodiment, the flat side of the baffle plate 52 faces the connecting cylinder 3, and the gap between the grate holes 2 is adjusted as described above. When it is necessary to clean the grate holes 2, the adjusting plate 4 and the adjusting device 5 can be disassembled. Then, the baffle plate 52 is rotated from a 10° angle with the fixed plate 51 to a 170° angle, and then the fixed plate 51 is flipped so that its lower surface faces upward and it is installed in the mounting groove 41. At this time, the brush structure faces the side of the connecting cylinder 3. Then, under the action of the driving device 6, the brush structure can be blocked above the grate holes 2. By the relative rotation of the adjusting plate 4 and the connecting cylinder 3, the grate holes 2 can be cleaned, and the grate holes can be prevented from becoming blocked.

[0051] According to the concept of the present invention, the implementation of the drive device 6 is not limited. In this embodiment, the drive device 6 includes a converter plate 61 that is detachably and fixedly connected to the connecting cylinder 3, and an electric cylinder structure 62 mounted on the converter plate 61.

[0052] The above description is merely one embodiment of the present invention and is not intended to limit the invention. Those skilled in the art will recognize that the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
