The invention discloses a mine ventilation system capable of preventing air current from being inverted and circulated and a use method. The mine ventilation system comprises a mine ventilator inverted-air preventing control device which is composed of a valve plate (1), a rotary shaft (2), a bearing (3), a speed reducer (4), a limit switch (5) and a controller (6). The bearing (3) is installed on the wall of a fan air inlet pipe of a current stabilization section (11) of the ventilator and provided with the rotary shaft (2). The valve plate (1) and the rotary shaft (2) form a whole, and the valve plate (1) rotates around the rotary shaft (2) within the range alpha, wherein the alpha ranges from 0 degree to 90 degrees. The rotary shaft (2) is connected with the limit switch (5) and the speed reducer (4). The controller (6) controls the speed reducer (5) to operate. The limit switch (5) limits the rotation angle of the valve plate (1). The mine ventilation system has the advantages of being easy to operate, reliable in operation, low in energy consumption, high in practicability and the like, and can prevent air current from being inverted and circulated when multiple fans installed on a ventilator station in parallel operate not at the same time.
Description
technical field [0001] The invention relates to a mine ventilator, in particular to a ventilation system for preventing the reverse air flow of the mine ventilator, which is suitable for preventing the fan from shutting down in the ventilator station of the mine ventilation system and installing multiple fans instead of reverse air flow and circulation during simultaneous operation. It can be widely used in mine ventilation in black, non-ferrous, chemical and other industries. Background technique [0002] When the fan in the mine ventilation station is not running, the impeller may naturally rotate forward or reverse due to the natural wind flow, and the reverse air flow will inevitably affect the normal ventilation of the mine ventilation system. , The natural rotation of the impeller will also affect the safe maintenance of the motor. In addition, when multiple fans are installed in the fan station, only part of the fans need to operate during the downhole air demand red...
