具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
参照图1-5所示，本发明提供了一种水煤浆提浓装置，包括研磨壳体1，研磨壳体1内连接有研磨机构，研磨壳体1的下方连接有过滤单元，过滤单元与研磨机构的出料口对应设置，过滤单元的下方对应设置有煤粉粒径分配机构，煤粉粒径分配机构用于分离不同粒径的煤粉，煤粉粒径分配机构的出端连通有搅拌器，搅拌器用于将不同粒径的煤粉搅拌成水煤浆；
研磨机构包括第一支架2，第一支架2固定连接在研磨壳体1内 侧壁上，第一支架2上连接有逐级研磨单元、第一调节单元与两组第二调节单元，第一调节单元连接在逐级研磨单元与第一支架2之间，两组第二调节单元对应设置在逐级研磨单元的两侧底部，第一调节单元用于同步调节逐级研磨单元的研磨间隙，两组第二调节单元用于统一逐级研磨单元的研磨间隙。
逐级研磨单元的主要作用是对煤块从大到小进行逐级粉碎，过滤单元的主要作用是过滤破碎后的煤粉颗粒，将大颗粒煤粉收集起来再次粉碎；第一调节单元的主要作用是减小逐级研磨单元之间的研磨间隙，过滤出的大颗粒煤粉进行研磨和粉碎；第二调节单元的主要作用是统一逐级研磨单元之间的研磨间隙，使所有的研磨间隙大小一致，便于重复对过滤出的大颗粒煤粉进行研磨和粉碎，一定程度上增加了煤粉的研磨时间，从而得到更多满足粒径需求的煤粉；搅拌器的主要作用是将不同粒径的煤粉中加入适量水和添加剂，最终搅拌成合格的水煤浆；煤粉粒径分配机构的主要作用是将不同粒径的煤粉进行区分，从而便于将合适粒径范围的煤粉进行混合，从而能够达到小颗粒煤粉充分吸附在大颗粒空隙内的目的，最终有利于形成高浓度的水煤浆。本申请通过干法研磨，制备合格粒径的煤粉，通过分选最佳粒径范围的煤粉，最终达到有效提升水煤浆浓度的目标。
进一步优化方案，逐级研磨单元包括两组第二支架4与两组第四支架29，两组第二支架4分别固定连接在第一支架2上，两组第四支架29滑动连接在第一支架2上，第一调节单元连接在两组第四支架29与第一支架2之间，两组第二支架4之间与两组第四支架29之 间竖向分别连接有两组研磨辊3，四组研磨辊3传动连接有驱动部，驱动部固定连接在第二支架4与第四支架29上，第二调节单元连接在位于第二支架4和第四支架29下部的两组研磨辊3上；位于第一支架2下方的两组研磨辊3与过滤单元顶部对应设置。
初始状态下，位于上方的两组研磨辊3之间的研磨间隙大于位于下方的两组研磨辊3之间的研磨间隙；大块的煤块首先被破碎为小块，然后进一步被破碎，在反复破碎的过程中，不断产生小颗粒的煤粉而透过过滤单元，滤出的大颗粒重新进行研磨；随着煤块尺寸不断减小，通过第一调节单元同步调节研磨间隙的大小，来满足研磨要求；随着煤块大小稳定，通过第二调节单元统一上下的研磨间隙，一定程度上增加煤块的研磨时间，从而得到更多的煤粉。
进一步优化方案，第二调节单元包括第一伺服电机7，第一伺服电机7固定连接在第一支架2的底部，第二支架4与位于第二支架4下部的研磨辊3之间设置有第一滑动调节部，第四支架29与位于第四支架29下部的研磨辊3之间设置有第二滑动调节部，第一伺服电机7通过丝杠8驱动第一滑动调节部与第二滑动调节部。
当需要统一上下的研磨间隙时，启动第一伺服电机7，同步驱动丝杠8，进而带动第一滑动调节部与第二滑动调节部，实现调节位于下方的两组研磨辊3之间的研磨间隙，从而保证上下研磨间隙一致。
进一步优化方案，第一滑动调节部包括第一空腔33与两组第二滑槽36，第一空腔33开设在第二支架4的底部内，两组第二滑槽36分别开设在第二支架4的底面和侧面上，第一空腔33与两组第二滑 槽36连通，第一空腔33内滑动连接有第一滑块6，第一滑块6的底部穿过一组第二滑槽36且还固定连接有第一套筒9，位于第二支架4底部的研磨辊3的转轴穿过另一组第二滑槽36且还与第一滑块6转动连接，研磨辊3的转轴穿过第一滑块6还与驱动部传动连接，第一套筒9螺纹套设在丝杠8的外侧，丝杠8的一端与第一伺服电机7的旋转轴同轴心固定连接。
具体的，两组第一伺服电机7通过丝杠8带动第一滑块6在第一空腔33内滑动，带动第二支架4下方的研磨辊3靠近或远离第四支架29，即研磨间隙缩小或增大，从而实现研磨出不同颗粒大小的煤粉。
进一步优化方案，第二滑动调节部包括第二空腔和两组第三滑槽，第二空腔开设在第四支架29的底部内，两组第三滑槽分别开设在第四支架29的底面和侧面上，第二空腔与两组第三滑槽连通，第二空腔内滑动连接有第二滑块30，第二滑块30的底部穿过一组第三滑槽且还固定连接有第二套筒31，位于第四支架29底部的研磨辊3的转轴穿过另一组第三滑槽且还与第二滑块30转动连接，研磨辊3的转轴穿过第二滑块30还与驱动部传动连接，第二套筒31套设在丝杠8的外侧，第二套筒31与丝杠8之间设置有传动组件。
具体的，两组第一伺服电机7通过丝杠8与传动组件带动第二滑块30在第二空腔内滑动，带动第四支架29下方的研磨辊3靠近或远离第二支架4，即研磨间隙缩小或增大，从而实现研磨出不同颗粒大小的煤粉。
进一步优化方案，传动组件包括第三套筒32，第三套筒32轴向滑动套设在丝杠8的一端，第二套筒31螺纹套设在第三套筒32的外侧。
进一步优化方案，煤粉粒径分配机构包括第三支架19，第三支架19上固定连接有分料壳体15，分料壳体15的一端固定连接有风机14，分料壳体15靠近风机14的一端顶部与过滤单元下方对应设置，分料壳体15的另一端固定连接有过滤器21，分料壳体15内开设有气流通道，风机14与过滤器21之间通过气流通道连通，分料壳体15外侧底部固定连接有分料箱16，分料箱16内沿气流通道方向依次开设有若干煤粉槽24，若干煤粉槽24分别连通在气流通道的底部，若干煤粉槽24的底部分别连通有排料组件。
通过启动风机14，设置固定风力，从过滤单元中透过的煤粉被风机14吹入气流通道内，根据不同粒径大小的煤粉，质量大的落在靠近气流通道入口处的煤粉槽24内，质量小的落在靠近气流通道出口处的煤粉槽24内，这样设置便可以有效将不同粒径范围的煤粉区别开，更快更有效的选取合适粒径范围的煤粉进行混合，有助于达到小颗粒煤粉吸附在大颗粒煤粉的空隙内的效果。
进一步优化方案，排料组件包括排料管17，排料管17竖向固定连通在分料箱16的底部，排料管17的底端固定连接有第二伺服电机18，第二伺服电机18的旋转轴穿入排料管17内且还固定贯穿有螺旋搅拌叶26，排料管17的底部一侧与搅拌器连通。
通过风机14分选的不同粒径的煤粉，在煤粉槽24内不断累积， 进入落料孔25内，再通过第二伺服电机18带动螺旋搅拌叶26，将煤粉输送入搅拌器中；搅拌器采用现有技术，通过搅拌器对不同粒径的煤粉进行混合，加入适量的水和添加剂，在不断搅拌过程中不断加入煤粉或水或添加剂，形成部分剪力要求和浓度的水煤浆。
进一步优化方案，沿风机14至过滤器21方向若干煤粉槽24尺寸依次增大；分料箱16靠近过滤器21一端底部开设有水槽35。
无论研磨间隙如何调整，每次研磨过程中，始终有大量的煤粉从过滤单元中透过，落入气流通道内，该部分煤粉数量不断积累，产量会大于大颗粒的煤粉，因此，存放小粒径煤粉的煤粉槽24尺寸相对较大；另外，水槽35内加入水，不断收集未落入煤粉槽24的煤粉，最终形成浑浊的煤粉溶液，该部分溶液可以加入搅拌器中，避免浪费；过滤器21为现有技术，可以将空气中无法收集在气流通道内的煤粉过滤，避免影响环境。
进一步优化方案，第一调节单元包括伺服液压缸28，伺服液压缸28的一端固定连接在第一支架2上，伺服液压缸28的另一端固定连接在两组第四支架29之间，第四支架29靠近伺服液压缸28的一侧固定连接有滑柱27，滑柱27与第一支架2滑动连接，第一支架2的滑动方向与伺服液压缸28的伸缩方向平行。
进一步优化方案，过滤单元包括振动筛12，振动筛12的顶部四角分别固定连接有弹簧10，振动筛12的一侧固定连接有振动电机13。
从漏斗11落下的煤块和煤粉经过振动筛12过滤后，可以将煤块中的煤粉过滤出，便于进一步区分不同粒径大小的煤粉，通过人工操 作也便于将煤块加入逐级研磨单元，继续研磨。
进一步优化方案，驱动部包括四组第三伺服电机22，位于下方的两组第三伺服电机22分别固定连接在第一滑块6与第二滑块30上，位于下方的两组第三伺服电机22的旋转轴分别穿过第一滑块6、第二滑块30与两组研磨辊3固定连接。
进一步优化方案，第二支架4与第四支架29的底部分别固定连接有电磁铁23，电磁铁23通电后分别与第一滑块6、第二滑块30吸合，第一滑块6与第二滑块30能够更加稳定，从而确保在研磨过程中研磨辊3的工作稳定性。
