Description

Technical Field

[0001] The utility model belongs to the technical field of blasting auxiliary equipment, in particular to a ventilation device in a blasting hole. Background Art

[0002] One of the most common operations in mineral mining is blasting. The dust content in the blasting hole formed after blasting is extremely high, and mining cannot be carried out. Therefore, the blasting hole needs to be ventilated after blasting. By placing a ventilation device in the blasting machine, the dust content in the blasting hole can be quickly reduced.

[0003] A Chinese patent application (or patent) with the announcement number CN215595632U discloses a ventilation device in a blasting hole, including a movable adjustment mechanism, a dust suppression mechanism is arranged on the movable adjustment mechanism, an exhaust filter mechanism is arranged on the movable adjustment mechanism, a dust concentration sensor is fixedly installed on the top of the movable adjustment mechanism, a controller is fixedly installed on the front of the exhaust filter mechanism, the exhaust filter mechanism includes a box body, an activated carbon filter is fixedly installed inside the box body, a dust inlet pipe is fixedly installed on the movable adjustment mechanism, and a fan with one end connected to the dust inlet pipe is fixedly installed on the left side of the box body. The ventilation device in the blasting hole can efficiently filter the dust generated in the blasting hole and quickly discharge it to the outside of the blasting hole by arranging the exhaust filter mechanism, thereby accelerating the circulation speed of the air in the blasting hole, thereby greatly improving the ventilation effect of the device and being highly environmentally friendly.

[0004] The above-mentioned ventilation device in the blasting hole is provided with an exhaust filter mechanism, and an activated carbon filter is provided in the exhaust filter mechanism. When absorbing and reducing dust, the wind with dust needs to be sucked into the activated carbon filter. The dust will adhere to the activated carbon filter and block the filter holes. The activated carbon filter is arranged inside the box body, and the machine needs to be stopped for disassembly and assembly, which is not conducive to timely replacement of the filter. In addition, a fan and an air outlet pipe are provided on it, and the blasting hole where the device is located is evacuated through the fan and the blow pipe. When evacuating, the part of the gas is discharged into the area around the device again to form a gas circulation. However, the exhaust area is only around the device, and the space range in the blasting hole is large, so the exhaust area and the exhaust area formed are extremely limited. To this end, we provide a ventilation device in a blasting hole to solve the above-mentioned problems. Utility Model Content
