Technical Field
The utility model relates to an automatic butterfly valve anti-freezing device that discharges of main fan comdenstion water belongs to mine ventilation technical field.
Background
In coal mines in northern areas, the temperature is low in winter, when the ventilator runs, the butterfly valve is in an open state, underground humid air is condensed into water at the diffuser, the silencer and the diffusion tower of the ventilator, and the condensed water is accumulated to a large extent. Due to the action of the wind flow, the condensed water is accumulated at the bottom of the silencer and the diffusion tower. At the time, the temperature of the underground airflow is high, and the condensed water cannot freeze. When the ventilator is shut down when the fan falls, the butterfly valve is closed, when the effect of wind power does not exist, condensed water accumulated at the bottom of the silencer and the diffusion tower naturally flows back to the bottom of the butterfly valve (the bottom of the butterfly valve is lower than the bottom of the silencer and the diffusion tower), and at the moment, the condensed water and a valve plate of the butterfly valve are frozen together at outdoor low temperature, so that the butterfly valve cannot be opened when the fan falls next time.
This condition will directly affect the downhole ventilation, a safety hazard with extremely serious consequences. Although the later stage has taken the butterfly valve ribbon heater measure of keeping warm, still have a lot of drawbacks, mainly have following problem:
firstly, fire hazard exists;
secondly, the electric heating belt needs to be continuously electrified for heat preservation, and electric energy is wasted;
