Description

Air supply device for mine construction

Technical Field

The utility model relates to the technical field of mine construction engineering, in particular to an air supply device for mine construction.

Background Art

Mining construction projects are mine construction projects. Mining construction projects mainly involve two major engineering projects: ground and underground. Due to the extremely poor environmental conditions and complex construction conditions of mine construction, high requirements for construction safety are placed on construction. Since the mine is underground and the air conditions are poor, air supply devices for mine construction are usually required to supply air to the interior to ensure sufficient air inside and maintain air circulation.

After searching, it was found that the Chinese patent announcement number is CN214997773U, which discloses an air supply device for mine construction. By setting a brush rod, when cleaning the ash on the grid, the first motor is started, so that the first motor drives the brush rod to rotate, and the rotation of the brush rod drives the bristles to clean the ash on the grid. The cleaned ash will fall to the bottom of the fixed ring and fall into the ash storage box through the connecting port at the bottom. The ash storage box can be unplugged from the connecting port to process the ash. In this way, the ash on the grid can be processed through the brush rod to prevent the accumulation of ash from affecting the air supply effect. The operation is convenient and quick, saving time.

However, after the bristles sweep away the dust, the dust will float around the grid. Under the influence of the wind force of the air supply device, the dust may re-attach to the grid, affecting the cleaning effect.
