卧轴式灰浆搅拌机是我国建筑施工中使用广泛的一种灰浆制备机械。前一时期笔者对全国大部分生产厂家的灰浆搅拌机进行了观察比较,发现绝大部分灰浆搅拌机的拌叶布置形式是相同的(图1)。这种布置形式已沿用了几十年,本文试图对这种布置形式的搅拌效果作一探讨。搅拌装置由安装在搅拌轴上的4组拌叶及拌筒组成。由于拌叶与其运动方向成45°夹角,所以拌叶组在其运动过程中,不仅能强迫物料作周向翻动,而且能迫使物料作轴向窜动(图2),从而将物料搅拌成均匀的灰浆。物料在搅拌时的轴向窜动方向及顺序 Horizontal shaft type mortar mixer is widely used in building construction in China as a kind of mortar preparation machinery. In the previous period, the author observed and compared the mortar mixers of most manufacturers in the country, and found that most of the mixing configurations of the mortar mixers were the same (Figure 1). This arrangement has been in use for several decades, and this article attempts to discuss the effect of this arrangement of mixing. The stirring device consists of 4 sets of mixing blades and a mixing drum mounted on a stirring shaft. Because the mixing leaves are at an angle of 45° with their direction of movement, the mixing blade group can not only force the material to make a turn during the movement, but also force the material to move axially (Figure 2), thereby stirring the material into Uniform mortar. Agitating direction and sequence of material during stirring
