Description

一种混砂设备
技术领域
本发明涉及油气田开采用混砂设备技术领域，具体涉及一种混砂设备。
背景技术
当前油气田压裂增产领域，混砂设备是压裂成套设备中的核心设备，其主要用于将上游供给的压裂基液、支撑剂、化学添加剂进行混合，最后将混合好的压裂液供给给下游泵送设备。
当前混砂设备在实际应用中主要有如下实现形式：
（1）、以柴油发动机驱动的形式为主，柴油机驱动的的设备存在诸多缺点：（a）、体积大、结构复杂：柴油机系统包含进气系统、排气系统、加热系统、燃油系统、冷却系统等，结构复杂，占用空间大；（b）、不环保： 柴油发动机驱动的混砂设备在井场运行过程中，会产生发动机废气污染和噪音污染，严重影响周围居民的正常生活，同时燃油、机油、防冻液等均有泄漏风险，会对环境造成一定程度的污染。（c）、不经济： 柴油发动机驱动的混砂设备，设备初期的采购成本比较高，设备运行时单位功率燃料消耗费用高，动力系统的日常维护保养费用也很高。
（2）、纯电驱动混砂设备，即混砂设备中的所有执行元件都由电动机驱动，电动机与各执行元件一对一驱动，整个混砂设备上的电动机个数多，且部分执行元件需求功率大，相应的电动机驱动功率要求也就大，电动机功率大，自然体积就大。由此带来的问题：无论是电动机个数多，还是某些单个大功率电动机，都会对混砂设备整体布置带来极大困难，为了实现全电驱动，往往需要牺牲很大的结构空间，最终导致混砂设备整体尺寸变大、重量加大，不利于运输及井场布置，且因空间限制，混砂设备整体维护保养便利性也差。
发明内容
本发明的目的克服现有技术的不足，提供一种混砂设备，本专利通过变传统的柴油发动机驱动为电动机驱动，保留液压系统，全部动力采用电驱液的形式，实现电动机作为动力源的环保节能等优势的同时，兼顾液压系统驱动部件体积小、布置灵活的优势。以此来解决传统混砂设备在应用中存在的不环保、尺寸大、运输及井场布置不便及维护便利性差等问题。
本发明的目的是通过以下技术措施达到的：一种混砂设备，所述混砂设备包括电动机和液压系统，所述电动机作为液压系统的动力源，所述液压系统驱动混砂设备中所有的执行元件。
进一步地，所述电动机为2台以上。
进一步地，所述电动机为变频一体机。
进一步地，所述混砂设备包括排出离心泵，吸入离心泵，混合系统，输砂装置和承载装置，所述排出离心泵，吸入离心泵，混合系统和输砂装置集成在承载装置上，所述电动机和液压系统也集成在承载装置上。
进一步地，所述承载装置为半挂车或车载或橇座。
进一步地，所述承载装置上集成有气源系统。
进一步地，所述混砂设备为本地控制和/或远程控制。
进一步地，所述混砂设备包括液添系统，干添系统，冷却系统和管汇系统，所述管汇系统设在承载装置长度方向的两侧，输砂装置设在承载装置长度方向的一端，混合系统与输砂装置相邻设置，干添系统设在混合系统的上方，所述液添系统与干添系统相邻设置，排出离心泵和吸入离心泵设在管汇系统中，电动机和冷却系统设在承载装置长度方向的另一端，所述冷却系统设在电动机的上方，所述液压系统与电动机相邻设置。
与现有技术相比，本发明的有益效果是：本技术方案通过变传统的柴油发动机驱动为电动机驱动，保留液压系统，全部动力采用电驱液的形式，实现电动机作为动力源的环保节能等优势的同时，兼顾液压系统驱动马达体积小、布置灵活的优势。以此来解决传统混砂设备在应用中存在的不环保、尺寸大、运输及井场布置不便及维护便利性差等问题。采用电动机驱动液压系统取代传统柴油机驱动或纯电动驱动，电动机相比于柴油机环保节能，电驱液相对于纯电动，减少了电动机的个数，大大节省了多个电动机的所占空间，使得整个混砂设备尺寸浓缩，重量减轻，更加利于运输及井场布置，整个混砂设备结构简单，整体维护保养便利性好。电动机采用变频一体机，变频单元直接集成在电动机上，无需额外配置变频单元，节约了变频单元所占空间，有效利用电动机的空间，保证整个混砂设备尺寸最优，同时避免了因独立变频单元散热系统故障带来的风险隐患。
