Abstract

本发明公开了一种无梁振动筛，属选煤厂分级脱水设备，主要用于煤炭的分级或者脱水。自承重筛板兼作横梁，激振梁兼做侧板，无专门的侧板。因此，更换筛板方便，总体高度小，质量轻，驱动功率小，结构简单，运转可靠。

Description

一种无梁振动筛 
技术领域
本发明涉及一种无梁振动筛，主要用于煤炭的分级和脱水，属选煤设备。 
背景技术
当前，圆振动筛和直线振动筛为了提高其筛框的强度，布置了许多横梁，这种结构不仅使结构相对繁琐，管梁较多，参振质量大，能耗也高；并且在更换筛板时，由于受横梁的阻碍，操作不方便。 
发明内容
本发明针对上述问题，提出了一种新的振动筛，具有结构简单，参振质量小，更换筛板方便的特点。 
本发明的技术方案是：一种无梁筛，包括电动机，挠性联轴器，激振器，筛箱以及减振装置，其特征是：筛箱包括筛框和筛网，筛框由两根平行工字钢纵梁及自承重筛板组成，纵梁兼做激振梁和侧板，与料流方向平行；侧板梁通过减振弹簧安装在前、后弹簧支座上，侧板梁与自承重筛板连接构成筛框，筛框与筛网连接形成筛箱。激振器安装在纵梁上部平面上，并通过挠性联轴器与电动机相连，电动机固定在电机架上。 
其积极效果在于：整个筛框由两根平行工字钢纵梁及自承重筛板围成，在用料量、加工量方面比通常的振动筛大为减少；在结构复杂程度方面大大简化；在更换筛板时，非常方便；在整体强度、刚度方面大为提高，从而提高了振动筛运行的可靠性，驱动电动机功率也减小。 
附图说明
下面结合附图及实施例对本发明作进一步说明。 
图1为无梁振动筛的主视图； 
图2为无梁振动筛的左视图。 
图中：1.前弹簧支座，2.减振弹簧，3.侧板梁，4.后弹簧支座，5.自承重筛板，6.激振器，7.挠性联轴器，8.电动机，9.电机架。 
具体实施方式
如图1、图2所示，本发明包括电机架9、电动机8、挠性联轴器7、激振器6、筛箱以及减振装置，筛箱包括筛框和筛网，筛框由两根平行工字钢纵梁及自承重筛板5组成，纵梁兼做激振梁和侧板，与料流方向平行；侧板梁3通过减振弹簧2安装在前、后弹簧支座1、4上，侧板梁3与自承重筛板5连接构成筛框，筛框与筛网连接形成筛箱。激振器安装在纵梁上部平面上，并通过挠性联轴器与电动机相连，电动机固定在电机架上。激振器6安装在纵梁上部平面上，并通过挠性联轴器7与电动机8相连，电动机8固定在电机架9上。 
侧板梁3当侧板用，同时兼作安装激振器6的激振梁；自承重筛板5当筛板用，同时兼作横梁用。减振弹簧2安装在侧板梁3侧面，没有通常的横梁。 
筛子可以设计成圆振动筛，也可设计成直线振动筛。
