The middle of two strut beams at the lower part of the hopper is transversely provided with a hand brake. 在料斗下方的两根支梁中间横向安装有手闸。
Each shaft is connected to screw without core in material pipe, there is opening in middle section of material pipe, there is hopper on opening, and there is agitating device in hopper. 每根主轴都与料管内的无芯螺旋连接,料管中段上部开口,开口上设料斗,料斗内设搅料装置。
The result showed cold aerodynamics field in the furnace was steady. The jet was flowing downwards with a good rigidity and could reach the upper and middle region of hopper. Aerodynamics field showed a symmetric W-shaped field. 炉内空气动力场稳定,拱上气流下行刚性好,能够到达冷灰斗中上部区域,形成了对称的W型流场。
