Efficient calcining device for gypsum powder production
The invention discloses an efficient calcining device for gypsum powder production. The efficient calcining device furnace comprises a fluidized bed furnace body and a gas distribution plate arrangedin the fluidized bed furnace body; an exhaust hole is formed in the upper part of one side of the fluidized bed furnace body; a discharge hole is formed in the bottom of the inner cavity of the fluidized bed furnace body on one side of the exhaust hole; a vertical baffle is fixed on the side, close to the discharge hole, of the gas distribution plate; an overflow hole communicated with the discharge hole is machined in the part, close to the gas distribution plate, of the lower portion of the baffle; and multiple sets of ash blocking assemblies are arranged on the upper portion of the inner cavity of the fluidized bed furnace body and horizontally distributed above the gas distribution plate side by side, and the interval between every two adjacent ash blocking assemblies is gradually decreased in the direction close to the exhaust hole. The ash blocking assemblies are arranged at the exhaust hole, the blocking faces of the ash blocking assemblies can be adjusted according to the air volume, most of suspended powder is blocked on the premise that air is allowed to pass through, and therefore waste of the powder is reduced, and the high conversion efficiency of overall calcination is guaranteed.
本发明公开了一种用于石膏粉生产的高效煅烧装置，包括沸腾炉本体以及设置在沸腾炉本体内的气体分布板，沸腾炉本体一侧上部设置有排气孔，排气孔一侧的沸腾炉本体内腔底部设置有排料孔，气体分布板靠近排料孔的一侧固定有竖直的挡板，挡板下部靠近气体分布板的部分加工有与排料孔连通的溢流孔，所述沸腾炉本体内腔上部设置有多组挡灰组件，多组挡灰组件水平并排分布在气体分布板上方，且相邻挡灰组件之间的间隔朝靠近排气孔的方向逐渐减小。本发明通过在排气孔处设置挡灰组件，挡灰组件可根据风量大小进行抵挡面的调整，在允许风通过的前提下，抵挡大部分悬浮的粉料，从而降低粉料的浪费，保证整体煅烧的较高的转化效率。
