Description

A workshop dust exhaust equipment

Technical Field

The utility model relates to the technical field of workshop dust treatment, in particular to a workshop dust exhaust device.

Background Art

A dusty workshop refers to a workshop that generates a lot of dust during the production process, such as abrasive powder metallurgy, pharmaceutical and other workshops. Dust has a serious impact on human health and the environment. Therefore, the management of dusty workshops should be strictly enforced to ensure the safety of the production process, environmental hygiene and employee health. In order to ensure the internal environment of the workshop, ventilation and exhaust devices will be installed inside the workshop to ventilate the inside of the workshop. However, the current ventilation and exhaust devices have the following disadvantages:

1. The current ventilation and exhaust device only uses exhaust fans to extract the dust inside the workshop to the outside of the workshop. However, once the exhaust fan is installed, its angle is fixed and it can only suck the dust in the direction facing it, resulting in a limited suction range. Therefore, the efficiency of dust suction needs to be improved;

2. After the existing ventilation and exhaust devices extract the dust out of the workshop, they will also reduce the dust, but continuous dust reduction will waste water resources.

Therefore, the utility model proposes a workshop dust exhaust device to address the above shortcomings.
