全密封输送机配重处粉尘现状及治理措施

Present Situation and Control Measures of Dust in Counterweight Place of Full Sealed Conveyor

本文针对全密封上托辊下气垫粮食输送机皮带配重处粉尘扩散严重、粉尘浓度高、员工工作环境恶劣、清理困难、易引发粉尘爆炸等问题,通过调查分析,查明泄漏部位及原因,对输送机系统进行了在配重处加装气流挡板及带清扫作用的粉尘回收装置的改进,并对改进后的装置进行实践验证。实践证明,技改方案能有效解决全密封粮食输送机配重处粉尘泄漏严重、粉尘浓度超标等问题。

Aiming at the roller under the air cushion conveyor belt at the grain weight of dust diffusion is serious, the high concentration of dust, the staff working environment is poor, difficult to clean up, easily lead to dust explosion problems such as seal, through investigation and analysis, find out the leakage position and causes, the conveyor system was improved and dust recovery device with air in weight and the baffle at the belt cleaning, and the improved device are verified. Practice has proved that the technical transformation scheme can effectively solve the serious dust leakage at the counterweight place of the sealed grain conveyor and the excessive dust concentration.
