Technical Field

[0001] The present application relates to the technical field of ventilation and dust removal, and in particular to a ventilation and dust removal device. Background Art

[0002] When collecting coal underground, it is necessary to ensure that there is sufficient oxygen in the well, and at the same time, attention should be paid to the dust generated during the collection process. Therefore, ventilation and dust removal equipment is required when working underground. After searching, the patent document with the authorization announcement number CN219431873U announced a ventilation and dust removal equipment, including a box body, the interior of the box body is divided into four chambers by a "cross"-shaped partition, and the four chambers are respectively a blast chamber, a filter chamber, a spray chamber and a water storage chamber. The top of the box body is equipped with a main air inlet through a fixing, and a secondary air inlet is provided on one side of the box body, and an air outlet is installed on the outer wall of the other side of the box body. The overall design of this ventilation and dust removal equipment is novel and the structure is simple. It not only has ventilation and dust removal effects, but also can humidify the filtered air to avoid the air in the mine being too dry, which greatly improves the comfort of miners working underground and is worthy of wide promotion and use.

[0003] It was found in actual use that the above-mentioned related schemes still have at least the following shortcomings: when used for dust removal, ventilation and humidification underground, part of the clean water sprayed from the spray rack will fall into the water storage chamber from the through hole. Long-term use will cause the liquid level in the water storage chamber to continue to rise, and it is necessary to discharge the water in the water storage chamber regularly, resulting in a waste of water resources, and thus unable to reasonably utilize water resources, and does not have the effect of saving water resources. Therefore, we propose a ventilation and dust removal equipment to solve the above problems. Utility Model Content
