Description

研磨装置、基于聚丙烯酰胺粉末的支撑剂混合系统 技术领域
本发明涉及聚丙烯酰胺技术领域，特别涉及研磨装置、基于聚丙烯酰胺粉末的支撑剂混合系统。
背景技术
石油支撑剂又叫石油压裂支撑剂。石油天然气深井开采时，高闭合压力低渗透性矿床经压裂处理后，使含油气岩层裂开，油气从裂缝形成的通道中汇集而出，此时需要流体注入岩石基层，以超过地层破裂强度的压力，使井筒周围岩层产生裂缝，形成一个具有高层流能力的通道，为保持压裂后形成的裂缝开启，油气产物能顺畅通过。
石油支撑剂如专利申请201610492751.9公开的液固一体化石油支撑剂，其为涂有水溶胀高分子涂层的颗粒，其中，所述水溶胀高分子涂层由以下组份组成，各组分以重量份计：占总重量50％的聚合物：聚丙烯酰胺；占总重量25％的高分子粘合剂：酚醛树脂；占总重量25％的阳离子聚合物：阳离子改性淀粉和阳离子聚丙烯酰胺；所述颗粒选20-50目陶粒颗粒、石英砂，其与高分子涂层的重量比为25:1。
石油支撑剂主要成分包括聚丙烯酰胺粉末、石英砂以及溶剂水等，由于聚丙烯酰胺吸湿性较高，采用传统的混料装置如专利申请201820781616.0公开的一种石油压裂支撑剂生产用混合装置，直接将大批量的聚丙烯酰胺、水混合，会由于聚丙烯酰胺吸湿量大，导致其局部团聚或者导致溶液的粘稠度过大，影响其后续混料。
另外，由于聚丙烯酰胺粉末本身吸湿性较强，若每次均采用新鲜的空气对研磨后的聚丙烯酰胺粉末进行吹送，会导致每一批次研磨后的聚丙烯酰胺粉末含水量均较大；且吹送的空气中会含有一定量的聚丙烯酰胺粉末，直接排放，污染环境以及导致原料的浪费。
现有技术的聚丙烯酰胺研磨机在兼顾防尘时存在加料麻烦，需要人工计量后、投料、封盖等多项操作，存在操作麻烦的技术问题。
发明内容
本发明针对现有技术技术问题之一是针对现有技术的聚丙烯酰胺研磨装置存在每一批次研磨后的聚丙烯酰胺粉末含水量均较大且吹送的空气中含有聚丙烯酰胺粉末而导致原料的浪费以及加料麻烦的技术问题，提供一种基于循环气流的聚丙烯酰胺研磨装置。
本发明针对现有技术技术问题之二是针对现有技术的聚丙烯酰胺粉末直接与大量水混合 存在粘稠度过大，影响其后续混料的技术问题，提供一种基于聚丙烯酰胺粉末的支撑剂混合系统。
本发明通过以下技术手段去解决技术问题之一的：一种基于循环气流的聚丙烯酰胺研磨装置，包括聚丙烯酰胺研磨机、旋风除尘装置、提气泵、进气管、出料管、出气管、循环管、阀门；
所述进气管的出气端与所述聚丙烯酰胺研磨机的进气口连通，所述出料管的两端分别与所述聚丙烯酰胺研磨机的出料口、所述旋风除尘装置的进料口连通；所述出气管的两端分别与所述旋风除尘装置的出气口、所述循环管的进气端连通，所述循环管的出气端与所述进气管的进气端连通；在所述循环管、所述进气管上均设置有所述提气泵、阀门；
所述聚丙烯酰胺研磨机包括聚丙烯酰胺研磨机本体以及进料装置，所述进料装置设置在所述聚丙烯酰胺研磨机本体的进料口处；
所述进料装置包括进料通道、储料槽轮、封口板、联动机构；所述进料通道上下导通，其底部与所述聚丙烯酰胺研磨机本体的进料口连通；所述储料槽轮限位在所述进料通道的内部腔体中且与所述进料通道转动连接，所述封口板与所述进料通道的顶部滑动配合；
所述联动机构用以带动所述储料槽轮、封口板联动，并保证所述储料槽轮转动至其开口槽朝下时能致使所述封口板滑动至闭合所述进料通道的顶部，所述储料槽轮转动至其开口槽朝上时能致使所述封口板滑动至所述进料通道的顶部开口。
本发明采用循环送风的方式，仅对第一批研磨后的聚丙烯酰胺粉末进行新鲜空气的吹送，经第一批研磨后的聚丙烯酰胺粉末吸湿后的干燥空气通过循环管循环送至进气管，实现干燥空气的重复送料，解决了后续批次聚丙烯酰胺粉末吸湿的问题。
由于研磨后的聚丙烯酰胺粉末在与空气混合时，一部分聚丙烯酰胺粉末会悬浮在空气中，本发明的基于循环气流的聚丙烯酰胺研磨装置，仅通入一次新鲜空气即可，减少了因每次新鲜空气吹入而带出研磨后的聚丙烯酰胺粉末的量。
本发明通过正反转第一转动轴，配合储料槽轮的开口槽，限定投料量，即可实现定量投料，实现定量投料、封盖等多道工序协同配合，简化了操作繁杂度。
优选地，所述联动机构包括第一转动轴、第一齿轮、第二齿轮、丝杆、第一传动装置、换向装置、第二传动装置、第二转动轴；所述第一转动轴通过第一轴承与所述进料通道的侧壁转动连接，所述第一齿轮套接在所述第一转动轴上且限位在所述进料通道的内部腔体中；所述第二齿轮套接在所述第二转动轴上，所述第二转动轴与所述进料通道的侧壁通过第二轴承转动连接，储料槽轮套接在所述第二转动轴上，且所述第二齿轮与所述第一齿轮啮合；所 述第二传动装置通过所述换向装置与所述第一传动装置传动，且所述第二传动装置的从动轮套接在所述丝杆上，所述丝杆的一端通过第三轴承与所述进料通道的顶部的一侧壁转动连接，所述丝杆的另一端贯穿所述进料通道的顶部并伸出所述进料通道的顶部的另一侧壁，在所述进料通道的顶部的另一侧壁上开设有通口；所述封口板能伸入至所述通口中且与所述丝杆配合，所述封口板相对所述通口移动能致使所述进料通道的顶部开口开闭。
本发明通过以下技术手段解决上述技术问题之二的：一种基于聚丙烯酰胺粉末的支撑剂混合系统，包括聚丙烯酰胺研磨机、旋风除尘装置、提气泵、进气管、出料管、出气管、循环管、储料仓、下料通道、间歇下料辊、环形水管、落料通道、折流通道、进料管、中转储料罐；所述进气管的出气端与所述聚丙烯酰胺研磨机的进气口连通，所述出料管的两端分别与所述聚丙烯酰胺研磨机的出料口、所述旋风除尘装置的进料口连通；所述出气管的两端分别与所述旋风除尘装置的出气口、所述循环管的进气端连通，所述循环管的出气端与所述进气管的进气端连通，所述提气泵分别设置在所述循环管、所述进气管上，阀门分别设置在所述循环管、所述进气管上；所述旋风除尘装置的底部通过输料管与所述中转储料罐的进料口连通；所述中转储料罐中的物料能输送至所述储料仓中，所述储料仓的下端开口，所述下料通道中位置较高的一端位于开口的下方，所述下料通道中位置较低的一端伸入至所述环形水管的环形通孔中；
所述环形水管设置在所述落料通道的上方且保证所述环形水管的环形通孔在竖直方向的投影完成落在落料通道的顶部开口区域中；所述环形水管上开设有进水口、出水口，多个所述出水口环绕在所述环形水管上，从所述出水口流出的水能喷射在所述环形水管的环形通孔中；
所述落料通道的底部与所述折流通道的顶部相通，进料管与所述折流通道的中段连通；
所述间歇下料辊与所述下料通道转动连接，所述间歇下料辊的两端与所述下料通道中对应的侧壁接触或者靠近所述下料通道中对应的侧壁；
所述间歇下料辊的截面呈圆缺状，其圆弧段向下时与所述下料通道的内底壁相切、其非圆弧段向下时与所述下料通道的内底壁之间存在空隙。
本实施例通过将待研磨的聚丙烯酰胺粉末通过聚丙烯酰胺研磨机的进料口投入至聚丙烯酰胺研磨机的研磨仓中，进行研磨。研磨后，通过开启各个提气泵、循环管中最靠近进气管位置的阀门关闭，其他阀门均开启，将外界空气从聚丙烯酰胺研磨机的进气口通过进气管吹入至聚丙烯酰胺研磨机的研磨仓中，将研磨后的聚丙烯酰胺粉末通过出料管吹入至旋风除尘装置中，利用旋风除尘装置的作用，使得研磨后的聚丙烯酰胺粉末沉降在所述旋风除尘装置 的底部，被研磨后的聚丙烯酰胺粉末吸湿后的干燥空气从旋风除尘装置的顶部通过出气管进入至循环管，供将下一批研磨后的聚丙烯酰胺粉末吹送至旋风除尘装置使用。干燥空气循环使用时候，关闭进气管上的提气泵、进气管上的阀门，其他提气泵、阀门开启。循环管的出气端位于进气管上的阀门、聚丙烯酰胺研磨机的进气口之间。在研磨过程中进料泵以及进料阀保持关闭。
需要储存研磨后的聚丙烯酰胺粉末时，通过关闭各个提气泵、阀门，开启输料管上的进料泵以及进料阀，研磨后的聚丙烯酰胺粉末流入至中转储料罐中缓存。
当需要将研磨后的聚丙烯酰胺粉末与石英砂进行混合时候，通过关闭各个提气泵、阀门，开启中转储料罐中与聚丙烯酰胺存储在储料仓连通的喂料管中的进料泵以及进料阀，研磨后的聚丙烯酰胺粉末通过喂料管喂入至聚丙烯酰胺存储在储料仓中，当然本发明也可以不在中转储料罐设置喂料管、进料泵，只是在中转储料罐的出口设置进料阀，需要研磨后的聚丙烯酰胺粉末与石英砂进行混合时候，开启中转储料罐的出口的进料阀，将研磨后的聚丙烯酰胺粉末取出后，人工喂入至储料仓中。在重力的作用下，聚丙烯酰胺通过储料仓的下端开口沿着下料通道导向(自上而下)流动；当间歇下料辊转动至其圆弧段与下料通道的内底壁相切时，间歇下料辊形成挡料板，将聚丙烯酰胺隔挡在下料通道中；当间歇下料辊转动至其非圆弧与下料通道的内底壁相对时，其与下料通道的内底壁之间存在空隙，部分聚丙烯酰胺通过空隙流入至环形水管的环形通孔中，实现了聚丙烯酰胺分批次、间歇下料。向环形水管上的进水口注入水，进水口通过多个出水口喷射在该批次的聚丙烯酰胺上，然后一同通过落料通道，进入至折流通道中，聚丙烯酰胺在折流通道中折流与水进行预混合，通过提料泵将石英砂以及其他助剂从进料管送入至折流通道的中段，与含水聚丙烯酰胺一同混合，从混合后从折流通道的底部流出，完成混合，混合后的支撑剂可以通过管体直接输送至施工处。
由于聚丙烯酰胺本身吸湿性较强，若每次均采用新鲜的空气对研磨后的聚丙烯酰胺粉末进行吹送，会导致每一批次研磨后的聚丙烯酰胺粉末含水量均较大。本发明采用循环送风的方式，仅对第一批研磨后的聚丙烯酰胺粉末进行新鲜空气的吹送，经第一批研磨后的聚丙烯酰胺粉末吸湿后的干燥空气通过循环管循环送至进气管，实现干燥空气的重复送料，解决了后续批次聚丙烯酰胺粉末吸湿的问题。由于研磨后的聚丙烯酰胺粉末在与空气混合时，一部分聚丙烯酰胺粉末会悬浮在空气中，本发明的基于聚丙烯酰胺粉末的支撑剂混合系统，仅通入一次新鲜空气即可，减少了因每次新鲜空气吹入而带出研磨后的聚丙烯酰胺粉末的量。
本发明实现了储料仓中的聚丙烯酰胺分批次、间歇流入至环形水管的环形通孔中，与喷射其中的水进行预混合，如此，避免了大批量的聚丙烯酰胺直接与大量的水直接混合而导致 的团聚、粘稠度大等问题。本发明通过多个出水口环绕在环形水管上，保证流入至环形水管的环形通孔中的聚丙烯酰胺能充分接触到水、减少或者避免未能接触水的死角出现；通过折流通道能延长聚丙烯酰胺与水的预混合时间以及程度，保证后续与石英砂等充分混合。

优选地，所述间歇下料辊套接在转轴上，所述转轴的两端分别通过轴承与所述下料通道中对应的侧壁转动连接，所述转轴的端部伸出所述下料通道与驱动电机的输出轴连接，所述驱动电机的固定端固定在机架上。
优选地，所述旋风除尘装置的数量为两个，两个所述旋风除尘装置通过连接管串联设置。
本发明的优点在于：由于聚丙烯酰胺本身吸湿性较强，若每次均采用新鲜的空气对研磨后的聚丙烯酰胺粉末进行吹送，会导致每一批次研磨后的聚丙烯酰胺粉末含水量均较大。本发明采用循环送风的方式，仅对第一批研磨后的聚丙烯酰胺粉末进行新鲜空气的吹送，经第一批研磨后的聚丙烯酰胺粉末吸湿后的干燥空气通过循环管循环送至进气管，实现干燥空气的重复送料，解决了后续批次聚丙烯酰胺粉末吸湿的问题。由于研磨后的聚丙烯酰胺粉末在与空气混合时，一部分聚丙烯酰胺粉末会悬浮在空气中，本发明的基于聚丙烯酰胺粉末的支撑剂混合系统，仅通入一次新鲜空气即可，减少了因每次新鲜空气吹入而带出研磨后的聚丙烯酰胺粉末的量。
本发明实现了储料仓中的聚丙烯酰胺分批次、间歇流入至环形水管的环形通孔中，与喷射其中的水进行预混合，如此，避免了大批量的聚丙烯酰胺直接与大量的水直接混合而导致的团聚、粘稠度大等问题。本发明通过多个出水口环绕在环形水管上，保证流入至环形水管的环形通孔中的聚丙烯酰胺能充分接触到水、减少或者避免未能接触水的死角出现；通过折流通道能延长聚丙烯酰胺与水的预混合时间以及程度，保证后续与石英砂等充分混合。

间歇下料辊103与下料通道102转动连接，间歇下料辊103的两端与下料通道102中对应的侧壁接触或者靠近下料通道102中对应的侧壁。
如图13、14所示，间歇下料辊103的截面呈圆缺状，其圆弧段向下时与下料通道102的内底壁相切、其非圆弧段向下时与下料通道102的内底壁之间存在空隙。
如图2、13、14所示，间歇下料辊103套接在转轴10102上，转轴10102的两端分别通过转轴轴承与下料通道102中对应的侧壁转动连接，转轴10102的端部伸出下料通道102与间歇下料辊电机10101的输出轴连接，间歇下料辊电机10101的固定端固定在第二机架。
本实施例通过启动间歇下料辊电机10101，带动转轴10102转动，进而带动间歇下料辊103转动。
本实施例通过将待研磨的聚丙烯酰胺粉末通过聚丙烯酰胺研磨机1的进料口投入至聚丙烯酰胺研磨机1的研磨仓中，进行研磨。研磨后，通过开启各个提气泵3、循环管7中最靠近进气管4位置的阀门8关闭，其他阀门8均开启，将外界空气从聚丙烯酰胺研磨机1的进气口通过进气管4吹入至聚丙烯酰胺研磨机1的研磨仓中，将研磨后的聚丙烯酰胺粉末通过出料管5吹入至旋风除尘装置2中，利用旋风除尘装置2的作用，使得研磨后的聚丙烯酰胺粉末沉降在所述旋风除尘装置2的底部，被研磨后的聚丙烯酰胺粉末吸湿后的干燥空气从旋风除尘装置2的顶部通过出气管6进入至循环管7，供将下一批研磨后的聚丙烯酰胺粉末吹 送至旋风除尘装置2使用。干燥空气循环使用时候，关闭进气管4上的提气泵3、进气管4上的阀门8，其他提气泵3、阀门8开启。循环管7的出气端位于进气管4上的阀门8、聚丙烯酰胺研磨机1的进气口之间。在研磨过程中进料泵10012以及进料阀10013保持关闭。
需要储存研磨后的聚丙烯酰胺粉末时，通过关闭各个提气泵3、阀门8，开启输料管10011上的进料泵10012以及进料阀10013，研磨后的聚丙烯酰胺粉末流入至中转储料罐10015中缓存。
当需要将研磨后的聚丙烯酰胺粉末与石英砂进行混合时候，通过关闭各个提气泵3、阀门8，开启中转储料罐10015中与聚丙烯酰胺存储在储料仓101连通的喂料管10014中的进料泵10012以及进料阀10013，研磨后的聚丙烯酰胺粉末通过喂料管10014喂入至聚丙烯酰胺存储在储料仓101中，当然本发明也可以不在中转储料罐10015设置喂料管10014、进料泵10012，只是在中转储料罐10015的出口设置进料阀10013，需要研磨后的聚丙烯酰胺粉末与石英砂进行混合时候，开启中转储料罐10015的出口的进料阀10013，将研磨后的聚丙烯酰胺粉末取出后，人工喂入至储料仓101中。在重力的作用下，聚丙烯酰胺通过储料仓101的下端开口沿着下料通道102导向(自上而下)流动；当间歇下料辊103转动至其圆弧段与下料通道102的内底壁相切时，间歇下料辊103形成挡料板，将聚丙烯酰胺隔挡在下料通道102中；当间歇下料辊103转动至其非圆弧与下料通道102的内底壁相对时，其与下料通道102的内底壁之间存在空隙，部分聚丙烯酰胺通过空隙流入至环形水管104的环形通孔中，实现了聚丙烯酰胺分批次、间歇下料。向环形水管104上的进水口注入水，进水口通过多个出水口1042喷射在该批次的聚丙烯酰胺上，然后一同通过落料通道105，进入至折流通道106中，聚丙烯酰胺在折流通道106中折流与水进行预混合，通过提料泵将石英砂以及其他助剂从进料管10901送入至折流通道4的中段，与含水聚丙烯酰胺一同混合，从混合后从折流通道4的底部流出，完成混合，混合后的支撑剂可以通过管体直接输送至施工处。
由于聚丙烯酰胺本身吸湿性较强，若每次均采用新鲜的空气对研磨后的聚丙烯酰胺粉末进行吹送，会导致每一批次研磨后的聚丙烯酰胺粉末含水量均较大。本发明采用循环送风的方式，仅对第一批研磨后的聚丙烯酰胺粉末进行新鲜空气的吹送，经第一批研磨后的聚丙烯酰胺粉末吸湿后的干燥空气通过循环管7循环送至进气管4，实现干燥空气的重复送料，解决了后续批次聚丙烯酰胺粉末吸湿的问题。由于研磨后的聚丙烯酰胺粉末在与空气混合时，一部分聚丙烯酰胺粉末会悬浮在空气中，本发明的基于聚丙烯酰胺粉末的支撑剂混合系统，仅通入一次新鲜空气即可，减少了因每次新鲜空气吹入而带出研磨后的聚丙烯酰胺粉末的量。
本发明实现了储料仓101中的聚丙烯酰胺分批次、间歇流入至环形水管104的环形通孔 中，与喷射其中的水进行预混合，如此，避免了大批量的聚丙烯酰胺直接与大量的水直接混合而导致的团聚、粘稠度大等问题。本发明通过多个出水口1042环绕在环形水管104上，保证流入至环形水管104的环形通孔中的聚丙烯酰胺能充分接触到水、减少或者避免未能接触水的死角出现；通过折流通道106能延长聚丙烯酰胺与水的预混合时间以及程度，保证后续与石英砂等充分混合。

第一传动装置包括第一主动轮12461、第一从动轮12462、第一皮带12463。第二传动装置包括第二主动轮12471、第二从动轮12472、第二皮带12473。换向装置包括第一锥形轮12481、第二锥形轮12482。

本实施例通过转动第一转动轴1241，具体可以通过手摇或者电机带动其转动，第一转动轴1241转动带动第一齿轮1242转动，带动与第一齿轮1242啮合的第二齿轮1243转动，带动第二转动轴转动，带动储料槽轮122转动；同时第一转动轴1241转动带动第一主动轮12461转动，通过第一皮带12463传动，带动第一从动轮12462转动，带动第四转动轴12491转动，带动第一锥形轮12481转动，带动与第一锥形轮12481啮合的第二锥形轮12482转动，通过第二锥形轮12482换向，带动第五转动轴12492转动，带动第二主动轮12471转动，通过第二皮带12473传动，带动第二从动轮12472转动，带动丝杆1244转动，带动封口板123沿着丝杆1244的导向方向滑动，即封口板123相对通口移动。
由于储料槽轮122转动至其开口槽1221朝下时能致使封口板123滑动至闭合进料通道121的顶部，储料槽轮122转动至其开口槽1221朝上时能致使封口板123滑动至进料通道121的顶部开口。
本发明通过正向转动第一转动轴1241，调整储料槽轮122转动至其开口槽1221朝上时候，此时进料通道121的顶部是开口的，此时，将需要研磨的聚丙烯酰胺投入至开口槽1221中，然后反向转动第一转动轴1241，当储料槽轮122转动至其开口槽1221朝下时候，开口槽中的需要研磨的聚丙烯酰胺落入至聚丙烯酰胺研磨机本体11的研磨仓中，而此时封口板123滑动至闭合进料通道121的顶部，保证需要研磨的聚丙烯酰胺在密封的条件下进行研磨，防止外界灰尘的进入以及减少安全隐患。研磨后，通过空气一次或者多次循环吹送，将当前批次研磨后的聚丙烯酰胺粉末吹送沉降后，再正向转动第一转动轴1241，实现储料槽轮122 转动至其开口槽1221朝上而封口板123滑动至进料通道121的顶部开口，供下次投料使用。
