| description | The utility model particularly relates to automatic ventilation equipment for a coal bunker of a coal cleaning plant. The whole full-section side rolling type automatic ventilation equipment is composed of a left side rolling type roller blind, a right side rolling type roller blind, a manual crank switch device, a limiting door frame, a roller blind winding drum, a support and a mounting base. An air volume sensor and an air speed sensor are installed on the air inlet door side to form a signal collecting part, a remote control switch is arranged on a door frame, a door frame roller shutter needs to move left and right in the door frame, and a limiting switch, a multi-circle type encoder and the like are installed on the door frame. According to the automatic ventilation equipment for the coal bunker of the coal preparation plant, parameters in the coal bunker can be monitored all day long, the opening degree and the closing degree of the roller shutter can be adjusted, and the device can have better operabi |
