Description

Technical Field

[0001] This utility model belongs to the field of bauxite processing technology, and in particular relates to a dust suppression device for a bauxite grinding mill. Background Technology

[0002] Bauxite, also known as alumina or bauxite ore, is mainly composed of aluminum oxide, which is hydrated aluminum oxide containing impurities. It is an earthy mineral. In the processing, a grinding mill is usually used to refine the bauxite. The feeding mechanism of existing bauxite grinding mills is usually a funnel-shaped feeding pipe. Bauxite is fed by pouring it downwards, and then discharged through the discharge hopper after grinding.

[0003] When bauxite powder is discharged through the hopper, a small amount of dust is raised. This dust can scatter in all directions, affecting the air quality at the processing site. Therefore, a dust suppression device for bauxite grinding mills is needed. This device can draw the dust from the mill's discharge hopper into a filter box through a fan, thus collecting the dust and preventing it from scattering everywhere. This reduces the impact of dust on the processing site environment. Utility Model Content

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a fan to collect dust from the outside of the discharge hopper into a dust collection box via a dust suction head and a rotating pipe. The rotating pipe is driven to rotate via a connecting plate, which causes the dust suction head to swing back and forth, increasing the dust suction range. This achieves the goal of collecting dust from the discharge hopper of the grinding mill by drawing it into the filter box through the fan, thus preventing dust from spreading everywhere and reducing the impact of dust on the processing site environment.

The dual-shaft motor 8 is turned on to drive the belt pulley 9 to rotate, so that the belt pulley 9 drives the belt pulley 11 to rotate through the transmission belt 12. Then, the belt pulley 11 moves the inner wall of the groove 14 through the Z-shaped shaft 10, so that the connecting plate 13 drives the rotating pipe 3 to rotate back and forth. Then, the rotating pipe 3 drives the dust suction head 4 to swing back and forth, increasing the dust suction range. This allows the dust from the grinding mill discharge hopper to be sucked into the filter box by the fan, so that the dust can be collected and prevented from spreading everywhere, thereby reducing the impact of dust on the processing site environment.

The connecting plate 13 drives the rotating pipe 3 to rotate, causing the dust suction head 4 to swing back and forth, increasing the dust suction range. This achieves the goal of collecting dust from the grinding mill's discharge hopper by drawing it into the filter box, preventing dust from scattering everywhere, and thus reducing the impact of dust on the processing environment.
