Description
技术领域
本实用新型涉及油田压裂设备，尤其涉及一种用于压裂设备的搅拌器。
背景技术
在现有的油田压裂设备中，搅拌器的搅拌轴多数采用上端固定、下端自由的固定方式，由于在搅拌过程中下端的晃动，造成搅拌器易损；另外，由于搅拌轴通常为一体结构，当出现搅拌叶损坏情况后维修不便，对于在一个搅拌轴上有两个以上搅拌叶总成的搅拌器而言，上述问题更为突出。
发明内容
本实用新型针对上述现有技术的不足，提供一种用于压裂设备的搅拌器。其能使搅拌机运行更平稳，寿命更长。
本实用新型解决上述技术问题的技术方案如下：一种用于压裂设备的搅拌器，包括上搅拌叶总成、下搅拌叶总成、及搅拌轴，其特征在于，还包括分别设于所述搅拌轴的顶部和底部的上固定座和下固定座，所述上搅拌叶总成和下搅拌叶总成分别套装在所述搅拌轴的上部和下部，所述搅拌轴两端分别通过上轴承组和下轴承组与所述上固定座和下固定座连接。
本实用新型的有益效果是：由于采用上下固定的方式固定搅拌轴，避免了由于仅在上端固定而导致的搅拌轴晃动现象，可以有效提高搅拌效率，并减少了搅拌叶总成的损坏频率。
在上述技术方案的基础上，本实用新型还可以做如下改进。
进一步，所述搅拌轴包括上搅拌轴、下搅拌轴及通过法兰与所述上、下搅拌轴连接的连接轴，所述上搅拌轴通过联轴器与上固定座连接。
采用上述进一步方案的有益效果是，在上、下搅拌叶总成之间设置连接轴，不仅便于设备的拆运、现场安装，而且在需要检修或调整搅拌叶角度时可以快捷拆换。
进一步，所述上固定座包括连接电动机的马达座，所述下固定座包括依次设置的翼座、基座、轴承盖及轴套，所述下轴承组安装在所述轴套中。
采用上述进一步方案的有益效果是，上固定座可以直接连接动力，下固定座由于采用翼座，更便于在搅拌罐中放置固定。
进一步，所述下轴承组包括单向推力轴承及深沟球轴承。
采用上述进一步方案的有益效果是，利用单向推力轴承的轴向大负载特性支撑搅拌叶重量；利用深沟球轴承的调心特性使搅拌机运行更稳定。
进一步，所述搅拌轴为空心轴。
采用上述进一步方案的有益效果是，采用空心轴能在保证刚性的同时减轻设备重量。
进一步，所述上部搅拌叶呈水平设置，下部搅拌叶呈倾斜设置。
采用上述进一步方案的有益效果是，上部搅拌叶呈水平设置有利于使待搅拌液向下翻动；下部搅拌叶呈倾斜设置有利于使待搅拌液向上翻动，从而形成更好的搅拌效果。
进一步，所述联轴器为星型垫弹性联轴器。
采用上述进一步方案的有益效果是，采用星型垫弹性联轴器可避免由于搅拌轴的少许径向晃动对电机轴的精度影响，而且使两者拆装方便。
