Description

一种钻井液用堵漏剂凝胶膨胀体筛分装置 技术领域
本实用新型涉及物料筛分领域，尤其涉及一种钻井液用堵漏剂凝胶膨胀体筛分装置。
背景技术
随着油气勘探开发的进一步深入，在高陡构造、边远区域及高山地区油气深井钻井过程中，钻遇大裂缝、溶洞性复杂漏失地层逐渐增多，成为困扰油气勘探开发顺利进展的主要技术难题之一。目前，国内外处理大裂缝、溶洞型漏失的技术主要是大颗粒、高浓度桥塞堵漏浆技术，水泥浆堵漏技术，清水强钻措施等。由于漏失通道大，仅靠桥堵材料实现高强度封堵难度较大；由于地层出水等原因，水泥浆在漏层的驻留能力不足，地层水稀释后的水泥浆不能形成有效封固层；清水强钻需要具有较好的地质和工程条件，如钻遇井段的井壁稳定能力和水资源充足等。
现设计一种堵漏剂来解决上述技术难题，在堵漏剂生产加工操作过程中，需要对其凝胶膨胀体进行筛分，而现有的装置在进行筛分时时固定不动，长时间使用容易导致筛孔堵塞，使得筛分效率降低，因此，为了解决此类问题，我们提出了一种钻井液用堵漏剂凝胶膨胀体筛分装置。
实用新型内容
本实用新型提出的一种钻井液用堵漏剂凝胶膨胀体筛分装置，解决了现有的堵漏剂凝胶膨胀体筛分效率低的问题。
为了实现上述目的，本实用新型采用了如下技术方案：

所述筛分箱的两侧均固定连接有摇摆杆，且所述底座的顶端设有与摇摆杆配合的限位机构，两个所述摇摆杆相互靠近的一侧固定连接有连接杆，且所述连接杆位于筛分箱的下方，所述连接杆的杆体上固定套接有两个呈对称分布的安装架，且所述安装架的内部固定连接有套筒，所述连接杆贯穿套筒，且所述套筒的两端均转动安装有安装杆，所述安装杆的端部延伸至安装架的外部，且固定连接有转动轮，所述转动轮转动安装与驱动板的圆周侧壁。
作为优选的，所述筛分箱的两侧均开设有出料口，且所述出料口处安装有出料挡板
作为优选的，所述驱动机构包括驱动电机、驱动杆、安装槽、驱动锥形齿轮和从动锥形齿轮，所述底座的一侧固定安装有驱动电机，且所述底座的内部开设有安装槽，所述安装槽的两侧内壁之间转动安装有驱动杆，且所述驱动电机的输出轴与驱动杆固定连接，所述驱动杆的杆体上固定套接有两个呈对称分布的驱动锥形齿轮，所述安装槽的顶端内壁转动安装有两个呈对称分布的从动锥形齿轮，且所述从动锥形齿轮与驱动锥形齿轮啮合，所述从动杆的底端延伸至安装槽内部 与从动锥形齿轮固定连接。
作为优选的，所述限位机构包括支撑杆、限位板和限位槽，所述底座的顶端固定连接有两组呈对称分布的支撑杆，且同组的两个所述支撑杆的顶端之间固定连接有限位板，两个所述限位板相互靠近的一侧均开设有限位槽，所述摇摆杆远离筛分箱一侧的上段固定连接限位杆，且所述限位杆滑动安装于限位槽内部。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。
参照图1和图4，一种钻井液用堵漏剂凝胶膨胀体筛分装置，包括底座1和筛分箱3，底座1的顶端设有筛分箱3，筛分箱3的顶端设有开口，且筛分箱3的底端均匀开设有筛孔，筛分箱3的两侧均开设有出料口，且出料口处安装有出料挡板4，底座1的顶端转动安装有两个呈对称分布的从动杆7，从动杆7的顶端固定连接有呈倾斜设置的驱动板8，且驱动板8呈圆台状，底座1的内部设有与从动杆7配合的驱动机构，驱动机构包括驱动电机2、驱动杆16、安装槽17、驱动锥形齿轮18和从动锥形齿轮19，底座1的一侧固定安装有驱动电机2，且底座1的内部开设有安装槽17，安装槽17的两侧内壁之 间转动安装有驱动杆16，且驱动电机2的输出轴与驱动杆16固定连接，驱动杆16的杆体上固定套接有两个呈对称分布的驱动锥形齿轮18，安装槽17的顶端内壁转动安装有两个呈对称分布的从动锥形齿轮19，且从动锥形齿轮19与驱动锥形齿轮18啮合，从动杆7的底端延伸至安装槽17内部与从动锥形齿轮19固定连接。
在进行筛分操作时，首先将待筛分的物料放置与筛分箱3内部，并且锁死出料挡板4，然后启动驱动电机2，驱动电机2带动驱动杆16转动，驱动杆16带动驱动锥形齿轮18转动，驱动锥形齿轮18与从动锥形齿轮19啮合，从而能够驱使从动锥形齿轮19转动，从动锥形齿轮19带动从动杆7转动，使得从动杆7带动驱动板8转动。
参照图1-3和图5，筛分箱3的两侧均固定连接有摇摆杆9，且底座1的顶端设有与摇摆杆9配合的限位机构，限位机构包括支撑杆5、限位板6和限位槽11，底座1的顶端固定连接有两组呈对称分布的支撑杆5，且同组的两个支撑杆5的顶端之间固定连接有限位板6，两个限位板6相互靠近的一侧均开设有限位槽11，摇摆杆9远离筛分箱3一侧的上段固定连接限位杆，且限位杆滑动安装于限位槽11内部，限位槽11呈弧形设置，两个摇摆杆9相互靠近的一侧固定连接有连接杆10，且连接杆10位于筛分箱3的下方，连接杆10的杆体上固定套接有两个呈对称分布的安装架15，且安装架15的内部固定连接有套筒14，连接杆10贯穿套筒14，且套筒14的两端均转动安装有安装杆13，安装杆13的端部延伸至安装架15的外部，且固定连接有转动轮12，转动轮12转动安装与驱动板8的圆周侧壁。

以上所述，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。
