A mud mixer with a lifting device
[Abstract] Mixers are widely used in chemical engineering ,biological engineering , petroleum engineering.medicine engineering and other industries.It is the most common and one of the most important unit of equipment .Its main functions are :(1)the function of mixing and dispersion homogenization ;(2)the function of mobile pelagic;(4)promoting the movement and heat moving of the material in the heterogeneous interface,and etc.Its operating performance is directly related to product quality ,energy consumption and production costs.
The traditional mixer is mainly consist of blender blades,stirring shaft and the reducer and motor,in the situation of drilling operations,the mud settle down for its large density while the agitator stopped working,and the blades will be buried deeply in the mud,which will decrease the life of the blades,Besides,it may make the motor burned out when the motor start suddenly.
Since the traditional blender exist these drawbacks,in this article,it designs a mixer with a lifting device by using related knowledge of mechanical principles and mechanical design based on the working situation,also,it has improved some structures compared with the traditional blender.This article focuses on the rotary device,lifting devices and impeller and makes deep discussion.It made several assumptions of options which were available,and have determined the final program.(1)Rotating device adopt bevel gear transmission.(2)Lifting device adopts screw nut transmission.Finally,the article has make a check of the strength of the some parts.
The agitator designed in this article is mainly for oil drilling occasions.Compared to the traditional blender,it has obvious advantages in the protection of the impeller and motor.
