湖南浏阳县城关镇合作工厂制造的脚踏离心式鼓风机,不但可用来炼铁,也可用于土法生产水泥.它的结构和制造简单,便于推广.一个木质飞轮,直径133公分,内灌砂石,依靠它在转动时冲动省力,在飞轮一旁的轴心上有两个小急弯,用两个铁钩钩着,下接踩脚板两个,用人力踩动飞轮就转动.轴心另一端安上一个齿轮,在衔接齿轮的另一根轴心上套上一个小齿轮和安上一个发动皮带盘,飞轮上的齿轮和发动皮带盘的齿轮大小比例是4∶1,因此飞轮转1转,发动皮带盘就转4转,发动皮带盘的直径是45公分,通过皮带系在鼓风机的小皮带盘上,小皮带盘直径是12公分,发动皮带盘与小皮带盘转动速度是1∶4.4.鼓风箱是用樟木做成的,外壳直径64公分,内空直径55公
The foot-operated centrifugal blower manufactured by the cooperation plant of Chengguan Town, Liuyang County, Hunan Province, can be used not only for ironmaking but also for the production of cement by earthwork. Its structure and manufacturing are simple and easy to promote. A wooden flywheel with a diameter of 133cm is used for sand filling. Stone, relying on it to drive while moving, there are two small sharp bends on the axis of the side of the flywheel, hooked with two hooks, two under the footsteps, and the maneuvering of the flywheel with manpower will turn. The other end of the axis Put on a gear, put a small gear on the other axis of the connecting gear and put on a belt pulley. The ratio of the gear on the flywheel and the gear of the starting belt pulley is 4:1, so the flywheel turns 1 turn. When the belt pulley is started, it will turn 4 revolutions. The diameter of the belt pulley is 45 centimeters. The belt is on the small belt pulley of the blower. The diameter of the small belt pulley is 12 centimeters, and the rotation speed of the belt pulley and the small belt pulley is 1:4.4. The bellows are made of eucalyptus, with a diameter of 64cm and a diameter of 55mm.
