Description

Technical Field

[0001] The utility model relates to the technical field of dust removal ash treatment, in particular to a grinding device for dust removal ash pretreatment. Background Art

[0002] Dust ash is produced during the smelting process of Cr-Ni stainless steel. The dust ash contains a large amount of heavy metal elements such as chromium and nickel. If it is not handled properly, it will not only cause a waste of resources, but also cause great harm to the environment. The dust ash needs to be ground before it is recycled so that it can be crushed to a suitable particle size. The existing grinding generally uses a ball mill or a rod mill. However, these traditional grinding equipment have some limitations. For example, although ball mills are widely used, their working efficiency is relatively low, and the equipment is bulky and complicated to operate. Rod mills also have problems such as limited processing capacity and high cost. These defects have affected the efficiency and benefits of grinding operations to a certain extent.

DETAILED DESCRIPTION

[0020] See also Figures 1 to 8 A grinding device for dust ash pretreatment comprises a frame 1, a grinding cylinder 2 and a grinding mechanism 3. The grinding cylinder 2 is arranged on the frame 1 through a cylinder 4. The distance between the grinding cylinder 2 and the grinding mechanism 3 is adjusted by the cylinder 4. The grinding mechanism 3 comprises a motor 5, a telescopic rod 6 and a grinding roller 7. The motor 5 is arranged on the frame 1 and the output shaft of the motor 5 passes through the upper part of the frame 1 and is connected to the telescopic rod 6. The end of the telescopic rod 6 is provided with a connecting piece 8 and extends into the grinding cylinder 2. The grinding roller 7 is connected to the connecting piece 8; a filter hole 9 is opened at the bottom of the grinding cylinder 2.

[0022] The telescopic rod 6 is composed of a telescopic sleeve 10 and a spline rod 11. The telescopic sleeve 10 is connected to the output shaft of the motor 5. The spline rod 11 is adapted to the inner wall of the telescopic sleeve 10. The spline rod 11 is arranged in the telescopic sleeve 10 and slides with the telescopic sleeve 10. One end of the spline rod 11 is connected to the connecting piece 8. A spring 12 is sleeved on the spline rod 11. Both ends of the spring 12 are respectively connected to the telescopic sleeve 10 and the connecting piece 8. When the grinding encounters solid impurities, the spring 12 contracts to prevent the grinding roller 7 from being damaged.

[0023] The grinding roller 7 is composed of a connecting rod 13 and a roller 14. The connecting rod 13 is connected to the side wall of the connecting piece 8. The roller 14 is arranged on the connecting rod 13 through a bearing 15. There are multiple connecting rods 13 and rollers 14. The friction force generated when the roller 14 contacts the dust will cause the roller 14 to rotate, grind the dust, and increase the grinding efficiency.

[0024] The drum 14 is provided with a protrusion 16, and the grinding efficiency is further improved by the protrusion 16.

[0025] The working principle of the utility model is as follows: when in use, dust is first put into the grinding cylinder 2, and then the motor 5 is started, the telescopic rod 6 is driven by the motor 5 to rotate, and then the grinding roller 7 connected thereto is driven to rotate, and the cylinder 4 is started synchronously, and the grinding cylinder 2 is driven by the cylinder 4 to move up, so as to ensure that the dust is fully in contact with the grinding roller 7, thereby increasing the grinding efficiency; when the grinding roller 7 rotates, the roller 14 rotates under the action of friction, so as to grind the dust while crushing it, thereby further increasing the grinding effect; the device has a simple structure and is easy to operate, the grinding roller 7 can be more fully in contact with the dust, thereby improving the grinding effect and uniformity, and making the grinding more refined and efficient; the dust with a suitable particle size falls from the filter hole 9, so that the staff can collect it for subsequent treatment.
