Abstract

本发明涉及一种演示设备,尤其涉及一种化学过滤实验用演示设备。本发明要解决的技术问题是提供一种结构新颖、操作方便、实验效果理想的化学过滤实验用演示设备。为了解决上述技术问题,本发明提供了这样一种化学过滤实验用演示设备,包括有左架、底板、支杆、放置板、放置框、固定板、烧杯、固定块、移动装置、摇柄、第一轴承座、第一转轴等;底板顶部左侧焊接有左架,左架右侧下部通过螺钉连接的方式连接有放置框,左架中部通过螺栓连接的方式连接有第一轴承座。本发明通过转动摇柄,摇柄通过第一转轴带动第一锥齿轮转动,第一锥齿轮通过与第二锥齿轮的配合,使得丝杆带动螺母上下运动。
The invention relates to a demonstration device and particularly relates to a demonstration device for a chemical filtration experiment. The demonstration device for the chemical filtration experiment has the advantages of novel structure, convenient operation and ideal experiment effects, and comprises a left frame, a bottom plate, supporting rods, a placing plate, a placing frame, a fixing plate, a beaker, a fixing block, a moving device, a rocking handle, a first bearing seat, a first rotating shaft, and the like, wherein the left frame is welded at the left side of the top part of the bottom plate; the lower part at the right side of the left frame is connected with the placing frame in a screw connection mode; and the middle part of the left frame is connected with the first bearing seat through a bolt connection mode. Through rotating the rocking handle, the rocking handle drives a first bevel gear to rotate through the first rotating shaft, the first bevel gear is matched with a second bevel gear, and thus, a screw rod drives a nut to move vertically.
