Description

一种钻井脉冲气压振动筛
技术领域
本发明涉及振动筛分设备技术领域，具体为一种钻井脉冲气压振动筛。
背景技术
随着石油钻井新技术的不断应用、钻井工艺水平的不断提高，需要处理的废弃钻井液日益增大，目前海上钻井废弃物的处置方式运输成本高昂，陆地储存占地面积超大，已经严重影响了钻井废弃物处理的进度，同时由于钻井废弃物因其含有的多种危害环境的化学成分，成为石油勘探开发过程中的主要污染源之一，对环境造成了严重污染。废弃钻井液振动筛作为废弃物处理***中的首要设备，对其处理钻井废弃物的处理量和效率有新的要求。目前传统的钻井液振动筛在钻井工程中筛网容易出现“堵筛”或者“糊筛”现象，从而使振动筛的处理效率降低。为了解决钻井技术发展所带来的钻井液处理量日益増大的问题，因此优化钻井废弃物振动筛的结构，提高其处理效率，降低钻井成本等，对于钻井效益和环境保护具有极高的工程意义。
发明内容
本发明的目的是为了设计一种能高效的解决海上钻井过程中产生的大量水基废弃钻井液的初级固液分离处理装置，达到废弃钻井液固液分离的设计目标，满足钻井废弃物不落地要求的一种钻井脉冲气压振动筛。
本发明的目的是这样实现的：
一种钻井脉冲气压振动筛，其特征是：所述底部舱室6安装在底座5下端，底部舱室6侧面安装有高压风机8与脉冲气压装置7，筛箱2安装在底座5上，筛网组成3安装在筛箱2底部，筛箱2上端固定有激振梁10，激振梁10上安装有直线振动激振器9，筛箱2上还安装有泥浆进料箱1，泥浆进料箱1上安装有电气控制***11。
本发明还包括这样一些结构特征：
1.所述筛箱2与底座5通过减振弹簧4连接。
2.所述直线振动激振器9安装有1-3个。
与现有技术相比，本发明的有益效果是：
本发明具有集成度高、结构紧凑、占地空间小、振动噪音小、易于维护等优点。本发明采用的脉冲气压装置，对筛网组成进行脉冲高压吹洗，可让振动筛网上的泥浆快速充分的脱水，同时可防止筛网堵塞，高效的提高固液筛分效率。本发明内部集成的微电脑控制***可与外控***联接通信，协同控制各电机运作，既能节能减排又能有效提高设备寿命。本发明作为海洋钻井平台废弃钻井液处理的第一级设备，能高效的实现大量废弃钻井液的初级固液分离，降低岩屑含液量，达到废弃钻井液固液分离的设计目标。联合后续废弃钻井液处理设备，最终实现将收集的废弃岩屑固体进行集中存放处理，废弃钻井液回收利用，满足钻井废弃物不落地要求。
附图说明
图1为本发明的主视图；
图2为本发明的轴侧视图；
图3为本发明的原理图；
图4为本发明的脉冲气压装置工作原理图。
具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述。
参考附图1、附图2，本发明的结构是：底部舱室6安装在底座5下部，用于承接筛分后的液相并输出，筛网组成3安装在筛箱2底部，两台直线振动激振器9安装在激振梁10上，激振梁10固定在筛箱2上部，泥浆进料箱1固定在筛箱2侧面，筛箱2通过减振弹簧4悬浮在底座5上，高压风机8与脉冲气压装置7连接，然后整体再与底部舱室6连接，电气控制***11负责控制电机运转及与外控***联结。
参考附图1、附图2、附图3、附图4，在激振器9的作用下，通过激振梁10传递带动整个筛箱2沿水平方向做往复运动，同时筛网组成3在激振器的作用下也作直线往复运动，废弃钻井液通过泥浆入料口进入泥浆进料箱1，在筛面的振动和往复运动中产生抛射与回落，并不断向前运动，致使小于筛孔的颗粒被筛选分离。同时高压风机8与脉冲气压装置7根据不同工况按一定周期规律对筛网组成3底部给与脉冲风压，使得泥浆液很容易通过筛网漏入底部舱室6，大于筛网孔眼的固体颗粒被筛出，从而实现固液分离，高效提升筛分效率。
参考附图1、附图2、附图3、附图4，脉冲气压装置7与高压风机8相连，高压风机8可提供设备必须的高压气体，脉冲气压装置7可根据不同工况按一定周期规律输出脉冲气压，对筛网组成进行脉冲高压吹洗，可让振动筛网上的泥浆快速充分的脱水，同时可防止筛网堵塞，能高效的提高固液筛分效率。
参考附图1、附图2，电气控制***11内部集成的微电脑控制***可与外控***联接通信，协同控制各电机风机运作，既能节能减排又能有效提高设备寿命。
