Vertical shaft fan
A draught fan sleeve and an air hole pipe are coaxially and fixedly connected to the bottom of a well lid from top to bottom in sequence, a plurality of ventilation holes are evenly formed in the range, corresponding to the interior of the draught fan sleeve, of the well lid, a motor box is coaxially and fixedly connected to the interior of the draught fan sleeve, and a driving motor is coaxially and fixedly connected to the interior of the motor box; the bottom end of a rotating shaft of the driving motor downwards extends out of the motor box and then is coaxially and fixedly connected with fan blades, ventilation openings are formed in the two opposite sides of the bottom of the side wall of the air hole pipe correspondingly, the bottom of the air hole pipe is a conical arc face inclining downwards in the direction from the axis to the edge, and the lower edges of the ventilation openings are flush with the conical arc face. The ventilation openings are distributed in a central symmetry mode with the axis of the air hole pipe as the center. According to the structure, according to the vertical shaft draught fan, the fan blades are driven to rotate through the driving motor, so that fresh air above a well lid is sucked into the horizontal pipeline, and waste gas in the horizontal pipeline is pumped out to the well lid to be exhausted outwards; therefore, the horizontal pipeline is circulated with the outside air.
本发明公开了一种竖井风机，井盖底部由上至下依次同轴心固定连接有风机套管和风孔管，井盖对应于风机套管内的范围内均匀设有多个通气孔，风机套管内的同轴心固定连接有电机箱，电机箱内同轴心固定连接有驱动电机，驱动电机的转轴底端向下伸出电机箱后同轴心固定连接有风叶，风孔管的侧壁底部的两相对侧分别设有通风口，风孔管的底部为沿着由轴心处至边沿处的方向、向下倾斜的锥弧面，通风口的下沿与锥弧面齐平，通风口以风孔管的轴心为中心呈中心对称分布。从上述结构可知，本发明的竖井风机，通过驱动电机驱动风叶的转动，从而实现将井盖上方的新鲜空气抽入水平管道、将水平管道内的废气抽出至井盖向外排出；从而使水平管道与外界空气循环流通。
