请结合图1、图2和图3，本发明第一实施例公开了一种泥沙浆筛分机100，包括：
圆筒筛机构1，用于将泥沙浆筛分为泥沙水及石块，水平振筛机构2，用于从泥沙水中筛分出沙子和细石，脱水机构3，用于将沙子脱水后运出，碎石机构4，用于将石块破碎后输出预定要求的石料。所述圆筒筛机构1、水平振筛机构2及脱水机构3依次设置，所述碎石机构4设于所述水平振筛机构2侧面，所述碎石机构4与所述圆筒筛机构1连接，所述圆筒筛机构1将泥沙浆筛分出的石块由所述碎石机构4移出并进行碎石操作。
可以理解，所述泥沙浆为工程渣土混合水之后形成的，其中含有泥水（泥土混合于水）、沙子、石块及其他杂物，石块含有粗石和细石，细石在圆筒筛机构1中被初步筛分，粗石需要进过碎石机构4进行破碎形成符合要求的细石。
可以理解，工程渣土在混合水和形成泥沙浆进入圆筒筛机构1内，初步筛分为泥沙水及石块，泥沙水中含有泥水及沙子，同时也含有少量细石，大部分石块被直接输出移动至碎石机构4，泥沙水继续沿着向前移动至水平振筛机构2，过程中被筛分为沙子和细石，细石则直接输出，沙子则进入到脱水机构3中进行干燥后输出。
可以理解，本发明提供的泥沙浆筛分机100可以将泥沙浆逐步筛分并输出符合要求的沙子和细石，所述圆筒筛机构1、水平振筛机构2及脱水机构3依次呈直线设置，结构布局紧凑，提高泥沙浆筛分运输的效率，同时在水平振筛机构2侧面设置碎石机构，使得圆筒筛机构1中输出的石块可直接运输至碎石机构4中进行破碎，不影响泥沙浆向前移动筛分的流程，机构之间互不影响，布局紧凑，提高空间利用率，特别是在大型的工程渣土筛分环境中，可以减少泥沙浆在移动筛分过程中的污泥堆积。
请参阅图2，所述圆筒筛机构1包括圆筒筛11及第一收集池12，所述圆筒筛11置于所述第一收集池12内。所述圆筒筛11包括进料端111和出料端112，泥沙浆在圆筒筛11内从进料端111移动至出料端112。所述圆筒筛机构1还包括第一提料组件13，所述第一提料组件13一端连接所述第一收集池12，另一端连接所述水平振筛机构2。所述圆筒筛11包括筒体113及搅拌芯114，所述搅拌芯114置于所述筒体113内，所述搅拌芯114与所述筒体113同轴设置，所述搅拌芯114位于所述筒体113内转动，所述搅拌芯114转动将泥沙浆从进料端111移动至出料端112。所述筒体113侧面包括移动段1131和筛网段1132，所述移动段1131和所述筛网段1132在泥沙浆的移动方向上依次设置，泥沙浆在所述移动段1131上移动进入所述筛网段1132内筛分。
泥沙浆从进料端111进入到筒体113内部，基于搅拌芯114的转动，使得泥沙浆被搅拌的同时，开始从进料端111向出料端112方向移动，在移动过程中依次经过移动段1131和筛网段1132，移动段1131为密封板结构，筛网段1132设有筛孔，在泥沙浆位于移动段1131的长度移动之后，泥沙浆被充分搅拌，并进入到筛网段1132，经过筛网段1132时，石块中较大的粗石继续在搅拌芯114的驱动下移动，而沙子和泥水以及部分细石穿过筛网段1132掉落到第一收集池12中，使得泥沙浆经过筛网段1132后，被分离为泥沙水和较大尺寸的石块（粗石），泥沙水落入第一收集池12内，粗石则从出料段112输出，并被送至碎石机构4。
可以理解，通过设置圆筒筛11，圆筒筛11基于转动的搅拌芯114在搅拌泥沙浆的同时驱动泥沙浆向出料端112方向移动，基于移动段1131的密封设置，使得泥沙浆在移动段1131上的移动得以充分搅拌，避免刚进入圆筒筛11的渣土未经过水的混合和充分搅拌，使得泥沙浆的筛分效率跟高，筛分更准确。
可以理解，所述搅拌芯114为螺旋搅拌芯，所述搅拌芯114转动搅拌泥沙浆并驱动泥沙浆移动，也即通过螺旋结构的转动下同时实现搅拌和驱动效果。
请结合图2和图3，所述第一收集池12包括落料池121，所述落料池121在对应所述进料端111的位置设有缺口1211，所述筒体113的进料端111置于所述缺口1211内，所述缺口1211为所述落料池121边缘的凹陷结构形成，所述筒体113的进料端111置于所述缺口1211内。
可以理解，通过设置所述缺口1211，使得筒体113可基于缺口1211下沉于落料池121内，降低进料端111的高度，避免过高的进料端111带来的进料不方便的问题。
可选地，作为一种实施例，所述缺口1211的高度位于所述进料端111的一半，使得筒体113部分下沉于落料池121内，部分高于落料池121，进一步方便用户将泥沙浆推入到筒体113内。
请继续结合图2和图3，所述落料池121包括凹陷部1212，所述凹陷部1212的长度与所述筛网段1132的长度匹配，所述筛网段1132筛分的泥沙水下落后进入所述凹陷部1212内。
可以理解，通过设置所述凹陷部1212的长度与所述筛网段1132的长度匹配，使得从筛网段1132下落的泥沙水首先落入到凹陷部1212内，而由于泥沙水中混合有沙子与细石，则沙子与细石会直接堆积在凹陷部1212中，混合有泥土的泥水则由于密度较低则位于沙子和细石上方，便于用户在落料池121中手机沙子与细石。
可以理解，在本实施例中，所述筛网段1132上开设有多个筛孔（图未示），所述筛孔的口径小于10mm，使得筛网段1132将石块按照10mm的标准筛分出粗石和细石，其中粗石大于10mm则被留置在筛网段1132内继续移动，而小于10mm的细石则掉落入落料池121内。
可选地，作为一种实施例，所述凹陷部1212侧面为斜面结构，使得凹陷部1212侧面具有引导作用，当下落的沙子和细石为掉落至凹陷部1212内时，可基于落料池121中水流的带动作用下移动，当移动至凹陷部1212侧面时，可基于斜面结构向下落入，让更多的沙子和细石进入凹陷部1212内。
请继续结合图1和图2，所述第一提料组件13包括传送带131和多个提料斗132，所述多个提料斗132依次等间距设于所述传送带131上，所述提料斗132上开设有多个漏水孔（图未示），所述传送带131一端置入所述凹陷部1212内。
使用时，提料斗132通过传送带131的带动下进入到凹陷部1212内，而基于传送带131端部的作用下，多个提料斗132从传送带131一侧转移到另一侧，转移过程中提料斗132铲起凹陷部1212内的沙子和细石，当提料斗132移动至传送带131另一端（顶端）时，再次在顶端位置转移到相反一侧上，提料斗132向下翻转的同时，将沙子和细石的混合物向下倾倒，进而输出至水平振筛机构2中，进入到下一个工序设备中。
可选地，作为一种实施例，所述传送带131的数量为多个，多个所述传送带131分设于所述筒体113的两侧，具体地，所述传送带131的数量为四个，并对称设置于筒体113驱动泥沙浆移动方向的两侧面，且传送带131靠近筒体驱动泥沙浆移动方向的一端面，使得筒体113的两侧可以设置较多的传送带131来运送沉入凹陷部1212内的沙子与细石。
请继续参阅图1，所述水平振筛机构2包括振筛机21和第二收集池22，所述振筛机21设于所述第二收集池22上方。所述水平振筛机构2包括第二提料组件23，所述第二提料组件23一端连接所述第二收集池22，另一端连接所述脱水机构3。所述振筛机21通过多层筛分设置，将第一提料组件13移动过来的沙子和细石的混合物料依次进行筛分，将沙子和细石分离，而沙子基于振筛机21的震动移动作用下重新掉落入第二收集池22内。
可以理解，所述振筛机21通过震动方式，将分离的沙子和细石在两个不同的位置向前继续移动，沙子移动而掉落入第二收集池22内进行二次洗沙，并通过第二提料组件23将第二收集池22内的沙子移动至脱水机构3内，而细石则通过指定的传送机构输出。
可以理解，输出的细石由于体积较小，则不需要进入碎石机构4内进行破碎处理，可以直接输出。
可以理解，所述第二提料组件23与所述第一提料组件13的结构相同，均是设置有传送带131和提料斗132，以通过提料斗132将水中的沙子移动到下一个工序中处理。
请继续参阅图3，所述落料池121外侧设有回流槽124，所述回流槽124一端连通所述落料池121，另一端连接所述第二收集池22，使得第二收集池22中存储的水源能够基于回流槽124重新回流至落料池121内，作为水资源的进一步回收利用，节约能源。
可以理解，第二收集池22中用于清洗沙子，而基于第一提料组件13的运送下，会有部分尚未流干的泥水或清水进入到第二收集池22中，使得第二收集池22中水位会不断增加，而增设了回流槽124，可将多于预设容量的水源回流至落料池121中（如图3中的b箭头形成的流向），作为水资源的进一步回收利用。
请继续参阅图1，所述脱水机构3接收提料斗132送来的沙子后，将沙子通过震动方式脱水，沙子经过脱水机构3的脱水干燥处理后，向外输出。
请继续参阅图1，所述碎石机构4包括碎石送料带41，所述碎石送料带41一端与所述出料端112连接，另一端连接石块堆放区42。所述碎石送料带41的传送方向与所述圆筒筛11移动泥沙浆的方向垂直，所述碎石送料带41将圆筒筛11内筛分输出的粗石（大于10mm的石块）转移至石块堆放区42中。
可以理解，所述碎石机构4将筛分输出的粗石从垂直方向上移出，也即泥沙浆基于圆筒筛机构1、水平振筛机构2及脱水机构3的直线型设置下形成一条直线型的筛分路线，而碎石机构4设置于水平振筛机构2的侧面上，基于碎石送料带41将筛分输出的粗石从直线型的筛分路线中取出，进一步减小设备的占地空间，提高空间利用率。
可以理解，所述石块堆放区42一侧设置有碎石间，用户将堆放的粗石投入碎石间中进行破碎处理，即可输出符合要求的石料。
请结合图2和图3，所述第一收集池12还包括回流池122，所述落料池121与所述回流池122相邻设置，所述落料池121与所述回流池122之间设有连通路123，所述落料池121、连通路123及所述回流池122之间形成一“U”型通路（如图3中箭头a形成的流向）。
可以理解，外部清水从缺口1211处流进圆筒筛11的进料端111，清水与渣土混合后，经过搅拌芯114的搅拌形成泥沙浆，泥水经过筛网段1132下落到落料池121中，而落料池121中的部分泥水经过连通路123回流至回流池122中，回流池122经过沉降将泥巴沉入回流池122底部，清水继续流动。
可以理解，所述回流池122的设置可避免落料池121中的泥水堆积过多而没过圆筒筛11的问题，增加圆筒筛机构1的过滤承载量，同时也让落料池121中的泥水流动至回流池122内，方便了用户对回流池122内的泥水进行处理。
请继续结合图1和图3，所述圆筒筛11置于所述落料池121内，所述回流池122与所述碎石机构4同侧设置，且所述回流池122设置于所述落料池121与所述碎石机构4之间，使得筛分设备具有更小的占地面积，提高空间利用率。
可选地，作为一种实施例，所述回流池122背离所述连通路123一端与所述缺口1211连通，使得泥水从落料池121流至回流池122后，通过缺口1211重新流入落料池121内，形成回流效果，同时也可基于回流池122的流水冲击力，作为将渣土推入圆筒筛11内的推动力，以提高渣土推进效率，节省能源。
可选地，作为又一种实施例，所述回流池122靠近所述连通路123一端设有过滤网125，所述过滤网125竖立于所述回流池122的入口处，使得从落料池121中漂流过来的泥水在进入回流池122之前，首先经过过滤网125的过滤，将部分石块及飘浮的杂物经由过滤网125挡住，使得流入回流池122中的泥水具有更低的杂质，提高过滤效率。
可以理解，在土方作业产生的工程渣土中，除了具有工程可重复利用的沙子、石块、泥巴及水，还会具有塑料、泡沫等生活工业垃圾，工业垃圾在落入落料池121中时，会飘浮于水面，基于水流流向而进入回流池122，此时则会被过滤网125遮挡而堆积于过滤网125上，提高了泥水的过滤效率，同时也便于用户在过滤网125位置收集和清理垃圾杂质。进一步地，过滤网125设置于水流方向上，利用了水流的驱动作用过滤垃圾杂质，进一步节省了能源。
可选地，作为又一种实施例，所述回流池122的深度小于所述落料池121的深度，使得回流池122的深度高于所述落料池121的深度。
请参阅图3，所述落料池121在背离所述缺口1211一端设置有吸水组件14，所述吸水组件14一端接入所述落料池121，另一端连接混合池18，所述混合池18用于沉降清水和泥巴。
所述混合池18顶部连接一储水组件16，底部连接压滤机15，所述压滤机15连接所述储水组件16，所述吸水组件14吸取落料池121内的泥水至混合池18中。
可以理解，所述吸水组件14包括一个离心泵，离心泵是指靠叶轮旋转时产生的离心力来输送液体的泵，实现将落料池121内的泥水抽出，并运送至压滤机15内，所述压滤机15将泥水加压，使得泥巴和水分离，获得干燥的泥巴与清水，而获得的清水则被输出至储水组件16中存储（如图3中f方向的流向），以对水能源的回收利用。
可以理解，所述离心泵在抽出泥水时，会混合有沙子，离心泵将混合有沙子的泥水首先进入到旋流器（图未示），此时通过旋流器的特性，使得重力较大的沙子重新落回落料池121内，而泥水则被离心泵抽出。
可以理解，所述吸水组件14将泥水抽送至混合池18中，泥水在进入混合池18之前，首先在泥水中添加絮凝剂，絮凝剂可以将泥水中混合的泥巴沉降于清水底部，在混合絮凝剂后，泥水进入到混合池18沉降，泥巴沉到混合池18的池底，则清水位于混合池18的上部，混合池18可以将清水移动到储水组件16内（如图3中e方向和f方向的流向），而底部的泥巴被移动到压滤机15中（如图3中d方向的流向）。
所述压滤机15及所述储水组件16设于所述落料池121背离所述水平振筛机构2一侧，所述储水组件16与所述落料池121的缺口连通，使得回收的清水可重新在缺口1211一侧流入，形成清水的回收-输出的回流（如图3中箭头c形成的流向），以通过回收清水的输出，作为推动渣土进入圆筒筛11的动力来源之一，进一步节省了能源。
可选地，作为一种实施例，所述储水组件16与所述落料池121之间设置有进料通道17，所述压滤机15、储水组件16、进料通道17及落料池121依次设置，且高度逐渐降低。
可以理解，所述进料通道17为放置工程渣土的空间，其连接落料池121的进料端111，而储水组件16输出回收的清水后先进入进料通道17内，作为推动渣土的动力来源之一，同时，清水在冲刷渣土也可以形成混合，将部分渣土混合形成泥沙浆，提高搅拌效率。
可以理解，所述压滤机15、储水组件16、进料通道17及落料池121依次设置，其连线形成的直线与泥沙浆的过滤工艺形成的直线平行，且压滤机15、储水组件16、进料通道17及落料池121高度依次逐渐降低，使得压滤机15将清水分离回收后，可以借助重力将清水排放至储水组件16中，同理，储水组件16基于用户的操作输出清水后，也可以借助形成的高低差，在重力的作用下冲刷进料通道17，为渣土进入圆筒筛11形成推动力，节约能源。
可选地，作为一种实施例，所述回流池122与所述进料通道17连通，使得回流池122中的泥水进入进料通道17，形成流水回路（如图3中a方向）。
所述回流槽124设于所述落料池121背离所述回流池122一侧，使得以落料池121为中心，形成一个环绕的水路***，提高空间的利用率。
可选地，作为又一种实施例，所述回流槽124与所述落料池121的缺口1211连通，从缺口1211进入，可先与渣土混合形成泥沙浆，提高泥沙浆混合形成的效率，让泥水重新回流与泥沙浆混合。
请参阅图4，本发明第二实施例提供一种泥沙浆筛分工艺，其采用上述第一实施例提供的泥沙浆筛分机1，包括以下步骤：
步骤S1：将渣土加入水，形成泥沙浆。
步骤S2：将加水的泥沙浆分离为泥沙水及石块，石块经过碎石后输出。
步骤S3：将泥沙水分离为泥水、沙子与细石，细石输出。
步骤S4：将分离的沙子浸入水中，沙子经过脱水后输出。及
步骤S5：将泥水经过高压分离，输出水和脱水的泥。
可以理解，在步骤S1中，渣土与水混合，在圆筒筛11中搅拌与水充分混合，形成泥沙浆。
可以理解，在步骤S2中，泥沙浆初步筛分为泥沙水（沙子、泥巴和水的混合物）、石块（粗石与细石），粗石经过碎石机构4破碎输出符合要求的石料。
可以理解，在步骤S3中，将泥沙水进一步筛分，获得泥水（泥巴与水的混合物）、沙子与细石，细石则直接输出。
可以理解，在步骤S4中，分离出的沙子浸入水中洗沙，进入到脱水机构3中脱水输出。
可以理解，在步骤S5中，通过压滤机15的压力作用下将泥巴和水分离。
可以理解，通过本方法提供的泥沙浆筛分工艺，可以将土方作业产生的渣土废料，分别筛分出沙子、泥巴、石块及水，沙子和石块可以作为建筑原料二次利用，泥巴可以作为砖厂烧制砖头的原料，做到了对土方作业产生的渣土废料的二次回收利用，提高了对能源的利用率，避免浪费。
本发明提供的一种泥沙浆筛分机及筛分工艺具有以下有益效果：
1、本发明提供的泥沙浆筛分机可以将泥沙浆逐步筛分并输出符合要求的沙子和细石，所述圆筒筛机构、水平振筛机构及脱水机构依次呈直线设置，结构布局紧凑，提高泥沙浆筛分运输的效率，同时在水平振筛机构侧面设置碎石机构，使得圆筒筛机构中输出的石块可直接运输至碎石机构中进行破碎，不影响泥沙浆向前移动筛分的流程，机构之间互不影响，布局紧凑，提高空间利用率，特别是在大型的工程渣土筛分环境中，可以减少泥沙浆在移动筛分过程中的污泥堆积。
2、通过设置圆筒筛及第一收集池，以将泥沙浆初步筛分为泥沙水和粗石，便于用于将粗石直接运出进行破碎，获得符合要求的石料，而基于第一提料组件将第一收集池内的泥沙水继续进入下一个工序筛分。
3、所述碎石机构将筛分输出的粗石从垂直方向上移出，也即泥沙浆基于圆筒筛机构、水平振筛机构及脱水机构的直线型设置下形成一条直线型的筛分路线，而碎石机构设置于水平振筛机构的侧面上，基于碎石送料带将筛分输出的粗石从直线型的筛分路线中取出，进一步减小设备的占地空间，提高空间利用率。
4、所述回流池的设置可避免落料池中的泥水堆积过多而没过圆筒筛的问题，增加圆筒筛机构的过滤承载量，同时也让落料池中的泥水流动至回流池内，方便了用户对回流池内的泥水进行处理。所述圆筒筛置于所述落料池内，所述回流池与所述碎石机构同侧设置，且所述回流池设置于所述落料池与所述碎石机构之间，使得筛分设备具有更小的占地面积，提高空间利用率。

7、所述回流槽与所述落料池的缺口连通，从缺口进入，可先与渣土混合形成泥沙浆，提高泥沙浆混合形成的效率，让泥水重新回流与泥沙浆混合。
