Abstract

The invention relates to the technical field of mine ventilation equipment, in particular to an automatic openable air door for metallurgy and an underground mine ventilation system. The automatic openable air door for the metallurgy comprises a driving device, a first connecting-rod mechanism and a first door body; the first connecting-rod mechanism comprises a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the first door body, the other end of the second connecting rod is hinged to one end of the first connecting rod, and a linkage mechanism is arranged between the other end of the first connecting rod and the driving device; the driving device is used for enabling the first connecting rod to rotate around a first set axis through the linkage mechanism so that the first connecting rod can pull the second connecting rod to move to make the first door body to be open and closed. The underground mine ventilation system includes the automatic openable air door for the metallurgy. By means of the automatic openable air door for the metallurgy and the underground mine ventilation system, the equipment investment of the air door can bereduced, the space required for installation is reduced, the air door is easy to disassemble, assemble and transport and convenient to maintain and install, the maintenance links are reduced, and thetransmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mine ventilation equipment, in particular to an automatic opening and closing damper for metallurgy and an underground mine ventilation system. Background technique [0002] The ventilation system is one of the important systems in underground mines. In order to realize the automation of underground ventilation, the work of each fan is linked, especially the parallel fans in the same fan station, and the metallurgical automatic opening and closing damper at the outlet of the fan diffuser is an important part of this control link. part, it can effectively cut off the wind flow and prevent the short circuit of the wind flow. In existing metallurgical mine applications, some large-scale electric butterfly valves are installed at the outlet of the ventilator diffuser to act as a damper, but the butterfly valve equipment is expensive, and the size of the equipment is also limited to underground transportation ...
