带式输送机底部清煤装置的设计制造及应用实践

    Design and application of bottom coal cleaning device for belt conveyor

    • 摘要: 为了解决带式输送机底部积煤问题,在借鉴煤矿井下带式输送机底部清煤装置研究基础上,黄陵二矿选煤厂设计制造出一种主要由小型推车、驱动装置、控制系统及辅助系统组成的带式输送机底部清煤装置,用于清理其底部积煤。现场应用实践表明:在该装置投入使用后,对于长度30 m、宽度1.90 m带式输送机的底部积煤,每次作业只需5 min,每个作业循环只需15 min。带式输送机底部积煤能够得到及时清理,清理积煤效率大大提高,工人劳动强度大幅降低,安全可靠性提升,影响带式输送机正常运行的不利因素得到消除。

       

      Abstract: In order to solve the problem of coal accumulation at the bottom of belt conveyors, based on the research of the bottom coal cleaning device of belt conveyors in underground coal mines, the Huangling No.2 coal preparation plant developed a belt conveyor bottom coal cleaning device, mainly composed of a small cart, drive unit, control systerm and auxiliary components, for cleaning the coal accumulated at the bottom. Field applications demonstrate that after the device is put into use, for the coal accumulation at the bottom of belt conveyors with length of 30 meters and width of 1.90 meters, each operation only takes 5 minutes, and each cycle only takes 15 minutes. The device enables timely cleaning of coal accumulation at the bottom of belt conveyors, improving the efficiency, reducing labor intensity, enhancing operational safety, and eliminating factors disrupting normal operation.
