煤仓及放料设备的设计与选用主要取决于产品性质、粒度、水份及粘度。用于细颗粒煤仓下的给料设备,尤其是掺有较多粘性大、水份高的浮选煤时,应采用什么方式放料? 淮南望峰岗选煤厂最先使用的是往复式给煤机。因给煤量小,振动大,后改用67°直通溜槽放煤。溜槽下端装有扇形闸门用以控制煤量。但使用情况很不理想,由于溜槽上口大,下口小,经常出现严重堵煤、闸门打不开等。鉴于上述两种设备的使用情况,设计了直流式电动放料装置。
The design and selection of bunker and discharging equipment depend mainly on the nature of the product, particle size, water content and viscosity. For feeding equipment under the fine coal bunker, especially when mixed with more viscous, high moisture flotation coal, what method should be put? Huainan Wangfenggang coal preparation plant is the first to use reciprocating Coal feeder. Due to small amount of coal, vibration, converted to a 67 ° direct chute coal. The lower end of the chute is equipped with a fan gate to control the amount of coal. However, the use of the situation is very unsatisfactory, as the chute catchy mouth, mouth is small, often serious coal clogging, the gate can not open and so on. In view of the above two kinds of equipment usage, the design of the DC electric discharge device.
