辽宁省劳动保护科学研究所最近研制成DX—1型多向干式凿岩孔口捕尘设备。这种设备可在下向、上向、水平及各种仰角等不同方向凿岩捕尘,弥补了GP—81型干式凿岩捕尘器单一下向凿岩之不足,并与其配套使用。使用这种捕尘设备后,作业环境粉尘浓度低于国家标准规定。该设备结构紧凑,
Liaoning Provincial Institute of Labor Protection recently developed into DX-1-type multi-directional dry drilling hole dust capture equipment. This equipment can drill down dust in different directions such as downwards, upwards, horizontal and various elevation angles to make up for the lack of single downhole drilling of GP-81 type dry rock drill dust collector and to be used together with it. After using this dust catching equipment, the working environment dust concentration is lower than the national standard. The device is compact,
