林西矿洗煤厂原煤及产品皮带取样,过去用人工,每班需设两个专人,每次取样时间间隔20分钟左右,费工、费力、准确性差。在学习兄弟单位经验的基础上,结合现场具体情况,自己动手制造了皮带自动取样机(附图)。现已在7个取样点分别安装使用。该机不需要专门设电机,依靠取样机处的皮带下方安装一个滚筒作为动力。每次取样间隔时间7～10分钟,每班只需一个人管理。
Linxi coal washing plant raw coal and product belt sampling, in the past with artificial, each shift needs to set up two special staff, each sampling interval of about 20 minutes, labor, laborious, poor accuracy. On the basis of learning the experience of our brother unit, we made our own automatic belt sampling machine (with photos) according to the specific conditions of the scene. Now in seven sampling points were installed to use. The machine does not require special motor, relying on the sampler at the bottom of the belt to install a drum as a power. Each sampling interval of 7 to 10 minutes, only one person per class management.
