Description

Technical Field

[0001] This utility model relates to the field of grinding media processing equipment technology, specifically to a non-powered grinding media screening and grading device. Background Technology

[0002] In the fields of cement mills or coal mills, grinding media are used as the medium for grinding and crushing materials. Among them, steel balls are the most common type of grinding media. They have high strength, high hardness and good wear resistance, and can effectively impact and grind materials. They are suitable for grinding materials of various hardnesses, and steel balls of different diameters can be selected according to different grinding requirements.

[0003] When the aforementioned steel ball grinding media are used, steel balls of different diameters are used in combination. At the same time, the steel ball grinding media will wear down and become smaller with use. As a result, after the steel balls are recycled, they need to be screened by a screening device before they can be reused. However, when the current screening device is used, a screen grinding media is usually used for screening. But the screen aperture inside the screening device is usually fixed, which limits the size of the grinding media that the screening device can screen and makes it less applicable.

[0004] In summary, there is a need for a grinding media screening device with easily adjustable screening aperture. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. 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.

[0024] To address the technical problems in the background art, the following non-powered grinding media screening and grading device is provided:

[0025] Combination Figures 1-5As shown, this utility model provides a non-powered grinding media screening and grading device, including a screening box 1. The top of the screening box 1 is equipped with a receiving mechanism 2 for feeding grinding media. Inside the screening box 1 are screening mechanisms 3 and 4, respectively. Screening mechanisms 3 and 4 are arranged correspondingly, and three sets of screening mechanisms 3 and 4 are provided inside the screening box 1. Multiple sets of screening mechanisms 3 and 4 can achieve grading and screening of the grinding media by setting different sizes of sieve holes. Screening mechanisms 3 and 4 are arranged at an angle inside the screening box 1. Screening mechanism 3 includes a mounting side plate 31, a mounting frame 32, a fixing plate 33, a screen 34, and a guide strip 35. The mounting frame 32 is located inside the mounting side plate 31, and a fixing plate 33 is fixedly mounted on the top surface of the end of the mounting frame 32. The inner side of the mounting frame 32 is provided with a screen 34 for screening grinding media, and the inner side of the mounting side plate 31 is provided with a guide strip 35. The guide strip 35 can fix the screening mechanism 4 and assist the stable movement of the screening mechanism 4. The screening mechanism 4 includes a mounting frame 41 and a screen 42. The mounting frame 41 is located on the top surface of the mounting frame 32, and the screen 42 is located inside the mounting frame 41. The mounting frame 41 and the screen 42 are engaged and slid with the mounting side plate 31. The screen 34 and the screen 42 are both made of steel strips arranged at equal intervals and obliquely. By engaging and sliding the mounting frame with the mounting side plate 31, the screen 42 can slide above the screen 34, so that the screen holes above the screen 42 and the screen 34 are misaligned, thereby achieving the purpose of adjusting the size of the screen hole diameter. This makes the device suitable for screening grinding media of various diameters.

[0026] In this embodiment, a guide bottom plate 16 is provided on the inner bottom of the screening box 1, and a guide collection bucket 12 corresponding to the screening mechanism 3 and the screening mechanism 4 is provided on the side of the screening box 1. The guide collection bucket 12 can discharge the screened grinding media away from the device. A baffle 11 is provided on the outer side of the screening box 1, and a guide plate 14 and a guide plate 2 15 are provided in the middle of the screening box 1. The inclined guide plate 14 and the guide plate 2 15 can guide the grinding media after being screened by the screening mechanism 3 and the screening mechanism 2 4 to fall above the screening mechanism 3 and the screening mechanism 2 4 for screening. The guide plate 14 and the guide plate 2 15 are both inclined. A discharge port 13 for discharging debris, dust and the smallest diameter grinding media is opened on the bottom side of the screening box 1.

[0027] In this embodiment, the screening mechanism 2 4 also includes an adjusting plate 43, an adjusting rod 44, and an adjusting knob 45. The adjusting plate 43 is located at the end of the mounting frame plate 2 41. The adjusting rod 44 is located in the middle of the adjusting plate 43. The adjusting rod 44 engages with the adjusting plate 43 and rotates. The adjusting rod 44 passes through to the outside of the fixed plate 33. The adjusting knob 45 is located at the end of the adjusting rod 44. The adjusting rod 44 is threadedly connected to the fixed plate 33. Through the threaded connection between the adjusting rod 44 and the fixed plate 33, the operator can rotate the adjusting knob 45 to control the mounting frame plate 2 41 and the screen 2 42 to move above the screen 1 34, so that the screen holes of the screen 1 34 and the screen 2 42 are misaligned.

[0028] As an improvement to the above solution, the fixed plate 33 is provided with a handle 36 on the side, and the mounting side plate 31 is engaged and slid with the screening box 1. After the device is used, the staff can pull the handle 36 to pull the screening mechanism 3 together with the screening mechanism 4 out of the screening box 1, which makes it more convenient for the staff to clean and maintain the screen 34 and the screen 42.

[0029] To ensure the effectiveness of the device in screening grinding media, this embodiment presents the following design:

[0030] In this embodiment, the receiving mechanism 2 includes a receiving hopper 21 and a distributing plate 22. The receiving hopper 21 is located at the top of the screening box 1. The distributing plate 22 is located inside the receiving hopper 21. Multiple sets of distributing plates 22 are staggered inside the receiving hopper 21. The multiple sets of distributing plates 22 can divert the grinding media after it enters the receiving hopper 21, so that the grinding media can be evenly distributed when it falls above the screening mechanism 3 and the screening mechanism 4 below. This avoids the situation where there is too much material in a local area during the feeding of the grinding media, resulting in insufficient screening.

[0031] As an improvement to the above solution, the receiving mechanism 2 also includes a valve plate 23, a support block 24 and a guide bar 35. The support block 24 is fixedly installed inside the screening box 1. The valve plate 23 is provided on the top of the support block 24. The valve plate 23 engages and slides with the screening box 1. A handle 25 is provided at the end of the valve plate 23. The valve plate 23, which engages and slides inside the screening box 1, can adjust the throughput of the grinding media under the action of movement adjustment.
