Description

Technical Field

[0001] This utility model relates to the field of cement mill technology, specifically to a steel ball gradation and sorting device. Background Technology

[0002] Cement mills are one of the key pieces of equipment in the cement production process. They are mainly used to grind cement clinker and appropriate amounts of gypsum, mixed materials, etc. into fine powder to produce cement products of different grades.

[0003] Steel balls of different diameters play different roles in a mill. Larger diameter steel balls mainly provide impact force to crush larger particles of material, while smaller diameter steel balls provide grinding force to grind the material into finer particles. As the mill runs, the steel balls will gradually wear down and their diameter will decrease. The impact force and grinding force of the worn steel balls on the material decreases, resulting in a reduction in grinding efficiency. In order to ensure that the steel balls in the mill are properly graded and to give full play to the role of steel balls of different diameters, it is necessary to screen the steel balls in the cement mill.

[0004] In summary, there is a need for a device that can classify and sort steel balls. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0024] To address the technical problems in the background section, the following steel ball gradation and sorting device is provided:

[0025] Combination Figures 1-3 As shown, the steel ball gradation and sorting device provided by this utility model includes a support 1, a movable frame 3 at one end of the support 1, a screening mechanism 5 for screening steel balls inside the movable frame 3, a guiding mechanism 4 for sorting steel balls in the middle of the support 1, a resting mechanism 2 for placing the screening mechanism 5 between the guiding mechanism 4 and the movable frame 3, a support rod 11 in the middle of the support 1, and the resting mechanism 2 includes a placement frame 21, a side plate 22, a resting rod 23, and a connecting rod 24. The placement frame 21 is located between the support 1 and the movable frame 3 and is inclined. The inclined placement frame 21 and the resting frame facilitate the inclined placement of the screening mechanism 5 above the resting mechanism 2. The top surface of the frame 21 is provided with a side plate 22, which is distributed in a mirror image. The side plate 22 has two sets of shelves, which are distributed parallel to the placement frame 21. The shelf includes a shelf rod 23 and a connecting rod 24. The shelf rod 23 and the connecting rod 24 are fixedly connected. The shelf rod 23 engages and slides with the side plate 22. Through the engagement and sliding of the shelf rod 23 with the side plate 22, the shelf rod 23 can easily support the placement of the screening mechanism 5 on the inside of the side plate 22. The shelf divides the upper part of the placement frame 21 into three placement areas, which are spaced apart. The three placement areas can hold screening mechanisms 5 with different screen hole sizes, thereby achieving the purpose of screening steel balls of different diameters.

[0026] When the steel ball grading and sorting device is used, it is first placed below the cement mill. When the steel balls are discharged after long-term use, they will fall above the screening mechanism 5. After the steel balls of different sizes are graded and sorted by the screening mechanism 5, the steel balls of different sizes will enter the guiding mechanism 4 from the three placement areas and be discharged in multiple directions. At the same time, the cement powder screened by the screening mechanism 5 will fall below the screening mechanism 5.

[0027] In this embodiment, the screening mechanism 5 includes a screening frame 51, a screen 52 and a movable rod 53. The screen 52 is provided inside the screening frame 51. The screening frame 51 is engaged with the placement area. The screen 52 can screen the steel balls discharged from the cement mill, separate steel balls of different sizes, and at the same time separate cement dust from the steel balls.

[0028] In this embodiment, multiple sets of movable grooves 31 are provided inside the movable frame 3, and a movable rod 53 is provided at the end of the screening frame 51. The movable rod 53 engages and rotates with the movable groove 31. Through the engagement and rotation of the movable groove 31 and the movable rod 53, the screening mechanism 5 can slide up and down and rotate along the movable groove 31 inside the movable frame 3. In this way, it is convenient to disassemble and store the screening mechanism 5 according to the needs of steel ball classification.

[0029] In this embodiment, multiple screening mechanisms 5 are provided inside the movable frame 3. The screening mechanisms 5 are correspondingly arranged with the movable groove 31. An opening is formed at the top of the movable groove 31. After long-term use, the screening mechanism 5 can be removed through the opening at the top of the movable groove 31, which is convenient for the staff to clean the screen 52 mechanism and avoid the problem of reduced screening effect of the screen 52 mechanism due to long-term use.

The baffle plate 6 divides the bottom of the support 1 into a dust collection area and a ball collection area. The dust collection area is used to collect cement dust that is screened out during the steel ball classification and screening.

[0033] In this embodiment, the guiding mechanism 4 includes a guiding box 41, a first partition 42, a second partition 43, a first guiding plate 44, and a second guiding plate 45. The guiding box 41 is inclined at the end of the placement mechanism 2. The inclined guiding box 41 can ensure that the classified steel balls are discharged from the outlet.
