    • An apparatus for feeding a granular catalyst to a destination such as a reactor at a constant feeding rate uniformly charges the catalyst material into the device. The granular catalyst is loaded into individual compartments of a hopper and is ejected at a discharge rate controlled by a gate. When a vibrator is activated, a trough is caused to vibrate in its obliquely upward direction and the granular material in the trough is smoothly conveyed toward outlets of granular material passages formed in the trough, and is introduced to reaction tubes of the reactor via sieves. Powdery waste of the granular catalyst produced by the vibration of the trough is removed by letting it fall the sieves made in the granular material passages.
    • 将粒状催化剂以恒定进料速度送入诸如反应器的目的地的装置将催化剂材料均匀地装入装置中。 颗粒状催化剂被装载到料斗的各个隔室中,并以由浇口控制的排出速率喷射。 当振动器被激活时,使槽在其向上倾斜的方向上振动,并且槽中的颗粒材料平滑地被输送到形成在槽中的颗粒材料通道的出口,并通过筛引入反应器的反应管。 通过将谷物的振动产生的颗粒状催化剂的粉末状废弃物通过使其落在粒状材料通道中制成的筛子而被除去。

    • A fan comprising: blowing units, each including a squarely hollow casing, an electric motor incorporated into the casing and an axial impeller coupled to the motor for generating an air flow from an inlet toward nozzles; the casing having one end opened to form the inlet and the opposite end opened to form the nozzles; and a guide which projects into the casing to arrange the nozzles in a parallel pattern, in a slit shape and in rows; wherein the blowing units are coupled together at adjacent sides thereof to be arranged in a row, each unit has the inlet provided with a bellmouth which surrounds impeller, and a space between each bellmouth and each casing is separated from an air flow path with the air flow generated by the impeller passing therethrough.
    • 一种风扇,包括:吹风单元,每个吹风单元包括正方形中空的壳体,并入所述壳体中的电动机和联接到所述电动机的轴向叶轮,用于产生从入口朝向喷嘴的空气流; 所述壳体的一端打开以形成所述入口,并且所述相对端打开以形成所述喷嘴; 以及引导件,突出到壳体中以将狭缝形状和排成一列的平行图案布置在喷嘴上; 其中吹风单元在其相邻侧面处联接在一起,以排列成一排,每个单元具有设置有围绕叶轮的喇叭口的入口,并且每个喇叭口和每个壳体之间的空间与空气流动路径与空气分离 由叶轮通过的流动。
