设计目的：避免背景技术中的不足之处，设计一种既能够采用风力既可以实现不同粒径机制砂的选择，又能够实现机制砂无尘的机制砂风力风选系统及风选方法。
 技术解决方案
设计方案：为了实现上述设计目的。1、机制砂风力风选器舱体的设计，是本发明的技术特征之一。这样做的目的在于：机制砂风力风选器舱体由五个相关联的舱室组成的一个整体，分别为一段强风舱室、二段强风舱室、三段中风舱室、四段料舱室和五段料舱室组成。(1)一段强风舱室与二段强风舱室由于机制砂的质量偏重，通过量偏大，因此处在其端面设有主风口之外还在其沸腾室的两侧设有付风口以补充风量，主风口和付风口的进风量受控于PLC控制器的控制。其中一段强风舱室的主风口与两个付风口使用一台主风机单独给风；二段强风舱室与三段中风舱室共同使用一台付风机给风；三段中风舱室由于其送料的数量与需要其吹送的机制砂的质量都已经减少，因此在三段中风舱室只设有主风口，其风量的来源为辅助风机所产生的风量。进料口下端的主风口强力给风，把机制砂用风力吹入相邻的沸腾室，并在沸腾室的两侧设有付风口以补充风量，使得机制砂在沸腾室内不断的被自下而上以及两侧的风力吹送。期间大颗粒的机制砂由于自身的质量超过风力的吹送，因此该级别的机制砂被落入一段强风舱室下面的出料口进入下一环节。经过沸腾室往上吹送的小一个级别的机制砂被送入一段强风舱室与二段强风仓室之间的过渡分料口，期间粉尘被处于五段料舱室上方的除尘器吸风口被吸走，质量大于粉尘而小于其他机制沙的细小颗粒落入到五段料收集斜溜槽上，被不断的送入五段仓。其余的机制砂由于自身质量的因素而被落入二段强风舱室的进料室内。(2) 二段强风舱室的进料室下端主风口不断的给出相对应的风量，把该段的机制砂不断的吹入二段强风舱室的沸腾室，并在二段强风舱室的沸腾室两侧设有付风口，以协助主风口给风，使得二段强风舱室中的机制砂不断的被自下而上的风量往上吹送，期间质量偏大的机制砂，由于自身重量的原因而被滞留在二段强风舱室的下料口部，并被不断的送入下一环节。二段强风舱室沸腾室中被往上吹送的机制砂中的粉尘部分继续被五段料舱室上口的除尘器吸走，其中五段料舱室料也落入第二个五段料收集斜溜槽上，并随着上一级五段仓料收集斜溜槽中的五段料一起落入五段仓。质量大于五段仓料的这部分机制砂被送入三段仓内。(3) 进入三段仓中的机制砂被下部的主风口所吹入的风量继续进入三段中风舱室的沸腾室，质量偏轻的机制砂被吹入四段仓内，质量偏重的这部分机制砂自然的就落入三段中风舱室的下部并被送入下一个环节。(4) 进入四段仓的机制砂也自然的落入仓底部，被送入下一个环节。从一段舱室到四段舱室的级别分离的机制砂分别经过各自舱室下端的管道被送入相对应的储存罐中。2、级配控制检验平台的设计，是本发明的技术特征之二。这样做的目的在于：在舱室底部与储存罐之间的管道一侧设有级配控制检验平台，该平台由一个多层实验用振动筛与振动筛所需层数相对应的可视称重级配器组成，该组检验平台起到控制每段舱室中机制砂级配调整作用，当某一舱室中的机制砂级配出现偏差时经过这个检验平台得出数据后立即调整相对应风机中主风管与付风管之间的进风管道阀门，经过对进风量的调整来控制该段机制砂的级配比例。可视称重级配器为一组相同容积的有机玻璃罐组成，并在罐体刻有相对应的刻度，工作人员根据每个罐体刻度的不同将非常直观的得出结论，再根据数据来对主风口与付风口之间的电动，气动管道阀门进行微调从而可以便捷的调整该段的机制砂级配比。亦可该可视称重级配器的底部都分别装有重量感应器，中央控制室的电脑中根据每个罐体的重量不同而自动的调节主风口与付风口的进风量。本申请所述的级配控制检验平台的设计并不局限于此，反涉及砂粒级别检测的检验平台均属于本发明的保护范围，如：激光检测、光电成像检测等等。3、机制砂风力风选器舱体的内部都拼接有不同尺寸的耐磨板的设计，是本发明的技术特征这三。这样做的目的在于：由于机制砂在风选的过程中对其内壁的磨损非常历害，在其壁上拼接不同尺寸的耐磨板，便于后期根据磨损情况方便更换耐磨板。4、一段舱室、二段舱室、三段舱室下料口、进料腔、沸腾腔的设计是本明的技术特征之四。这样做的目的在于：下料口可以直接将大于风力的机制砂直接筛选出来；而进料腔、沸腾腔设计，使进料腔内的机制砂在风力的作用了由下往上翻腾，并且在翻腾的过程中既达到了机制砂粒径的筛选，又分离了粉尘，实现了无尘机制砂的目的。在机制砂风力风选器舱体顶部都设有维修孔，以方便维修。
 有益效果
本发明与背景技术相比，一是采用模块化多层振动筛进行筛分的设计，在相同宽度幅面的前提下增加了筛分层面，在同等筛分层面的前提下减少了层间距，降低了整个振动筛的自重，不仅缩短了更换筛网的时间，简化筛分设备，节约投资，减少能耗，实现低碳化运作，而且结构设计合理，加工制造和安装方便，单机处理量大和模块维修成本低，使用寿命长；二是机制天然砂级配调整系统的设计，不仅适用于湿式制砂，而且适用于干法制砂，制砂过程中不会产生过磨现象，避免了成品中废弃的粉量的产生，既避免了对环境的污染，又避免了原材料浪费，其筛选下来的细钢珠可以作为抛丸来分级利用，而磨损的细小钢粉被电磁滚筒回收作为铸造原料，更重要的是该机制砂经过风选分离后可以达到江河沙这样的圆整度，并且该机制砂的粒径范围是可调整的，用户可以根据自身的需求而调整机制砂的粒径，细度模数；三是采用风力风选系统，不仅实现了对不同粒径机制砂风选的目的，而且所风选出来的各个级别的机制砂中的粉尘含量近乎为零，实现了机制砂风选无尘的目的。

参照附图2-1至2-10。模块化抽屉式多层振动筛，包括多层振动筛，所述多层振动筛中的筛板为模块化抽屉式振动筛6-2，且模块化抽屉式振动筛6-2与箱体6-1之间呈抽拉配合；模块化抽屉式振动筛6-2由模块组合式筛网托架装置D1、托架滑轨D2、筛网托架压紧装置D3和托架牵引装置D4组成，两根托架滑轨D2固定安装在振动筛侧墙板上，模块组合式筛网托架装置D1位于两根托架滑轨D2面上，筛网分别安装在模块组合式筛网托架装置D1上，托架牵引装置D4位于振动筛侧墙板端部，模块组合式筛网托架装置D1与托架牵引装置4中的牵引钢丝绳连接，托架压紧装置D3固定振动筛侧墙板内侧且托架压紧装置D3与固定模块组合式筛网托架装置D1呈锁定或开启配合。所述多个模块化抽屉式振动筛6-2筛面网孔的孔径各不相同，具体孔径根据实际筛选需要选定。
托架滑轨D2直接固定在振动筛的侧墙板上，由角钢或者其他达到滑轨作用要求的材料制成，该滑轨起到模块组合式筛网托架装置在其上面的直线滑动以及紧固后的支撑作用。
所述侧滑导向装置1-1包括了一组滑珠机构，该机构由半密封舱室与导向滑珠5-1以及辅助滑珠组5-2组成，导向滑珠5-1位于辅助滑珠组5-2中间且导向滑珠5-1珠面与辅助滑珠组5-2中辅助滑珠呈相对滚动配合。

参照附图2-4至2-9。本发明采用模块组合式筛网托架装置1在固定于侧墙板上的对称托架滑轨之间的平面滑动来实现模块组合式筛网托架装置的直线运动，该运动轨迹中采用了尾部托架装置前段下部两组对称导向滑条1-3与模块组合式筛网托架装置侧面的侧滑导向装置1-1来减少阻力并起到准确导向的作用。
参照附图2-8和2-9。模块组合式筛网托架装置1包含了托架导向侧滑装置1-1，该托架导向侧滑装置1-1包括了一组滑珠机构，该机构由半密封舱室与导向滑珠5-1以及辅助滑珠组5-2组成。该机构采用油脂润滑，该机构在模块组合式筛网托架装置受到牵引力作用下在振动筛箱体中滑动时起到减少阻力以及定向滑动的作用。
模块组合式筛网托架装置D1由头部筛网托架110、中部筛网托架1-9和尾部筛网托架1-8构成，头部筛网托架110与中部筛网托架1-9之间、中部筛网托架1-9与尾部筛网托架1-8之间均采用筛网托架软连接装置1-4连接（钢丝绳筛网托架），所述中部筛网托架1-9由一个或者是多个筛网支托架组成，且多个筛网支托架首尾间采用筛网托架软连接装置1-4连接，当把组合式筛网托架装置紧固在振动筛上的时候该软连接功能不起作用，当该模块组合式筛网托架装置被牵引时该软连接装置起到联接所有托架组件的作用。
所述尾部筛网托架1-8中包括侧滑导向装置1-1、定滑轮组1-2和一组导向滑条1-3，侧滑导向装置1-1位于尾部筛网托架1-8侧部，定滑轮组1-2位于尾部筛网托架1-8端部横梁上，尾部筛网托架1-8前段侧部分别装有相互对称导向滑条1-3。所述尾部筛网托架1-8侧部相互对称装有一个或多个侧滑导向装置1-1。
所述中部筛网托架1-9由一个或者是多个筛网支托架组成，且多个筛网支托架首尾间采用筛网托架软连接装置1-4连接。所述中部筛网托架1-9侧部相互对称装有一个或多个侧滑导向装置1-1。模块组合式筛网托架装置1的中中部筛网托架1-9中包括了侧滑导向装置1-1，该中部部分根据振动筛的规格尺寸不同而有增减，但最少不得少于一块。
参照附图2-10。所述头部筛网托架110中的牵引吊儿1-5位于端面固定板1-7中部，手柄1-6位于端面固定板1-7侧部，一个或多个侧滑导向装置1-1位于头部筛网托架110侧部。该组机构主要起到借助外力的前提下把模块组合式筛网托架装置拖拽到振动筛以外，以及端面固定模块组合式筛网托架装置的作用。
参照附图2-8。筛网托架压紧装置D3包括固定在振动筛侧墙板上的压紧架3-1和顶紧螺栓3-2以及侧墙板上相对应开孔组成。紧固筛网托架压紧装置3的工作在振动筛外侧操作，这样既方便操作又便于维修检查。侧墙板上的开孔还可以作为辅助观察孔来使用，也可以作为喷淋系统的接入口来使用。
参照附图2-5至2-7。托架牵引装置D4包含着轴承座4-1，钢丝绳4-2，钢丝绳卷筒4-3，手动或电动绞盘4-4，棘齿轮锁紧装置4-5，加力杆组成4-6。托架牵引装置4隐藏固定在振动筛出料段出料导板下面，该装置起到牵引模块组合式筛网托架装置就位的功能。该机构用手动或者电力驱动，在牵引过程当中棘齿轮锁紧装置4-5确保模块组合式筛网托架装置不会往后面倒滑而造成不必要的事故。其中钢丝绳4-2的长度根据操作工在平地上操作方便为恰当长度，以便于工人在平地上就可以进行两组托架装置的互换。
模块化抽屉式多层振动筛制作方法，首先将所需规格的合格筛网分别固定在模块组合式筛网托架装置D1上，并把托架牵引装置D4中的钢丝绳4-2拉伸到合适的地面，并与装好筛板的模块组合式尾部筛网托架装置中的两个定滑轮1-2装配完毕，然后连接与其他部分模块式组合式筛网托架之间的筛网托架软连接装置1-4相互连接并紧固，接着绞动托架牵引装置D4，拖拽组合式托架组往托架滑轨D2进口端处行走，在模块组合式筛网托架装置D1接近托架滑轨D2之时用先前固定在进料输送带头部的固定滑轮协助，首先送入模块组合式尾部筛网托架装置1-8，然后依次拽入剩余模块组合式尾部筛网托架装置1-8，行进至最后在头部托架部分进入托架滑轨D2之后，可借助外力推动整个模块组合式尾部筛网托架装置1-8就位，并通过螺栓将头部托架的1-7端面固定板与箱体连接固定，然后依次在振动筛两侧分别拧紧D3筛网托架压紧装置中的螺栓即可。由于振动筛在工作状态下筛网必须牢牢的固定在箱体当中，因此筛网托架与托架滑轨之间必须要平面接触，以便于D3筛网托架压紧装置拧紧的时候，这部分不至于还有滑动间隙，造成筛网在工作中自行跳动，因此在本发明中只是采用前段拖拽与1-1侧面点滑的方式加上尾部筛网托架前段的1-3两段半圆型导向滑条来减轻整个模块组合式筛网托架与托架滑轨之间的摩擦力。
当需要把筛板托架拽出振动筛时，只需在适当的位置固定定滑轮，配合拖拽钢丝绳与筛板托架头部的1-5牵引吊儿处缓慢拖拽，并配合托架尾部的D4托架牵引装置同步释放钢丝绳即可把整个筛板托架完整的拽出振动筛箱体。

筒体内包括了：进料口耐磨圈C34，布料式端衬板C35，布料衬板，反击式步进料斗，缓冲衬板及与除尘罩相衔接的迷宫密封部分组成。
动力源为四组同步变频调速电机与两组大滚圈组成。
除尘罩部分由与筒壁衔接的迷宫密封部分，除尘罩壳体，观察孔，与缓冲皮垫组成。
工作原理阐述：把需要整形与调整级配的机制砂与其媒介物（钢珠：钢筋切头等具有一定质量的钢材）按照一定比例混合后经过进料口耐磨圈被源源不断的送入级配调整机。该机制砂与钢珠混合物进入调整机内腔后由于级配调整机的不断旋转，于耐磨圈相连接的布料式端衬板上凸起的拨叉条的作用下物料被不断的翻滚，磨削，前进。
与布料式端衬板相连接的是布料衬板，该衬板与其他内部衬板和料斗都为高锰钢铸件，该衬板上的凸起拨叉条同样具有翻滚，磨削，送料的功能。
随着筒体的不断旋转，混合物料被不断的拨入反击式步进料斗内。随着筒体的旋转，下层装满混合物料的料斗被持续不断的提升到顶部，当料斗被提升到顶部时料斗内的混合物料被瞬时抛下，被抛落的钢珠直接击打到下面料斗的上平面与侧面的反击面和反击条上，此时这些反击面上的机制砂与钢珠就同时被击打，又由于设计的反击式步进料斗设计有许多不同折角的反击面与反击条，因此下落的钢珠会造成二次及多次的反复击打，在这反复的击打中机制砂被重复破碎。又由于筒体的不断旋转，存在与底部的机制砂与钢珠混合物被不断的翻滚，磨削，又不断的被下一级料斗提升。
由于该反击式步进料斗以沿着筒体单组从进料口到出料口直线排布，沿着筒壁周长以三组或者三组以上的步进式错位排列。以沿着筒壁周长三组为一个单位来进行描述：第二排的第一个料斗头部位于第一排的第一个料斗的中部，第三排的第一个料斗头部处在第二排的第一个料斗的中部，以此类推形成步进原理。
因此第一组顶部物料下落的位置是在下部料斗的第一个料斗与第二个料斗之间，并且随着筒壁的旋转，该料斗落下来的一半物料被第二个料斗提升，以此类推。因此，在物料不断的被提升抛下，也就不断的被步进式向前推进。
在物料向出料口推进的过程当中，被不断的提升，破碎，翻滚，磨削。
当物料被送到出料口段时为了瞬间减少物料中钢珠的弹跳力与冲击力，因此在出料段设计了反向安装的缓冲衬板，在缓冲衬板的反向拨叉条的作用下经过破碎磨削的混合物失去了提升力后在缓冲衬板上形成混合物的堆积区。该堆积区的物料随着筒壁的旋转，不断的被排出级配调整机，进入下一个工段。
级配调整机内部的工作状态是相对密封的，筒壁内随着机制砂不断的被提升下落，不断的被破碎，内部将产生大量的粉尘，因此在该设备的后部配备有除尘罩，该除尘罩与筒壁的连接为迷宫式连接，使得该处不会出现扬尘，除尘罩上端开有吸风口，筒壁内产生的粉尘经过吸风口进入除尘器，以降低粉尘的含量。除尘罩侧面为防止钢珠的弹跳力与冲击力，因此内壁设有缓冲皮垫，并在中部设有观察孔，以便于停机时观察筒壁内料斗与衬板的磨损情况等等，下部设有出料口以便于物料被运输到下一个工段。
出料段下端是一级与二级钢珠分离部，该部的工作原理为头部按有电磁滚筒的输送带，由于电磁滚筒的作用，不含磁性的机制砂抛向第二级钢珠分离部，被电磁滚筒磁性作用吸住的钢珠直接进入到溜槽C1，在第二级钢珠分离部的头部也是相同的一组电磁滚筒，已处理第一组滚筒中没有处理完毕的小钢珠与磨削产生的钢粉。并同时落入钢珠粒径控制溜槽C2。在这两级钢珠与机制砂分离过后，成品机制砂进入下一个机制砂斗提提至下一工段。钢珠粒径控制溜槽中靠近前段为开长腰孔的钢珠粒径控制段。该段把质量磨损，粒径偏小的钢珠与钢粉分离到细钢珠地槽。把质量合格，粒径合格的粗钢珠送入钢珠斗提仓内，经过斗提提升到级配调整机进料口的混合料斗内进行循环破碎机制砂工作。第二级钢珠分离部把钢珠与机制砂完全分离后，成品机制砂进入成品料斗提打入下一级分选设备。
以此不断的循环生产，在该生产线中的钢珠基本上不产生浪费，筛选下来的细钢珠可以作为抛丸来分级利用，经过不断的磨损的钢珠具有优良的钢丸作用，是铸件表面处理的优良原料，被电磁滚筒回收的细小钢粉，也可以作为铸造原料进行重新利用。
实施例2：在实施例1的基础上，一种无尘机制天然砂制作风选分离方法，石料通过石料输送机构A1至制砂机A的进料口，制砂机A将石料制成机制砂后从制砂机A的排料口排到机制砂输送机构A2始端面，机制砂输送机构A2末端将机制砂源源不断地落到模块化多层振动筛D进行筛分，筛分出的机制砂输送至机制天然砂机配调整系统B，机制天然砂机配调整系统B将机制砂制成机制天然砂至机制砂风力风选系统，机制砂风力风选系统中启动主风机010和付风机04，机制砂通过混合成品提斗机01中的料斗提升到混合成品提斗机01的上部且通过混合成品提斗机01的出料口进入缓冲料仓02内，缓冲料仓02将料仓中的机制砂输送至料机03，给料机03均匀的把机制砂料送入风力风选器舱体06的第一段强风舱室的进料口：
位于第一段强风舱室进料腔内的机制砂根据所选粒径的大小及重量调节主风机010进风风力的大小及付风机04进风风力的大小，在主风机010及付风机04的作用下通过主风口21和付风口22将进料腔内的机制砂吹到相邻沸腾腔内，超过风力的大颗粒机制砂由第一段强风舱室出料口进入第一段分级储料罐09内，小于风力的机制砂在沸腾腔风力的作用下由下往上吹入由第一段强风舱室和第二段强风仓室构成的第一段分料通道腔8后进入第二强风舱室内，其机制砂中的粉尘通过第五段上的除尘口6被吸尘器05吸走；

同理，进入第三强风舱室内的机制砂在主风机010的作用下将进料腔内的机制砂吹到相邻沸腾腔内，超过风力的大颗粒机制砂由第三段强风舱室出料口进入第三段分级储料罐09内，小于风力的机制砂在沸腾腔风力的作用下由下往上吹一部分进入第三段料仓室4、一部分进入第二段斜溜槽12导入第五段料仓室4，其机制砂中残存的微量粉尘通过第五段上的除尘口6被吸尘器05吸走。
机制天然砂级配调整系统天然砂的制作方法，进料输送带C1把需要调整级配的机制砂送入钢砂混合料斗C2同时，塔式钢珠斗提机C15通过进料溜槽C16向钢砂混合料斗C2添加钢珠，以上两种材料混合后进入机制砂级配调整机C3，经过机制砂级配调整机C3的不断旋转，在调整机中的步进式反击料斗C38的不断提升与不断步进的工作下，机制砂不断的被破碎、碾磨，然后从机制砂级配调整机C3出料口C44不断送出机制天然砂，在出料口上部的除尘器吸风罩C43的除尘孔C45不断的把机制砂级配调整机C3内部产生的粉尘吸走，机制砂级配调整机C3出料口C44下端是一级电磁钢砂分离器C6钢珠分离部，该钢珠分离部的工作为头部按有电磁滚筒的输送带，由于电磁滚筒的作用，不含磁性的机制天然砂抛向第二级电磁钢砂分离器C7分离部，被电磁滚筒磁性作用吸住的钢珠直接进入到钢珠出料溜槽C9，在第二级钢珠分离部的头部也是相同的一组电磁滚筒，已处理第一组滚筒中没有处理完毕的小钢珠与磨削产生的钢粉，并同时落入钢珠粒径控制溜槽C11，在这两级钢珠与机制砂分离过后，成品机制砂进入下一个机制砂斗提提至下一工段。

该钢珠与需要调整的机制砂共同进入机制砂级配调整机C3，机制砂级配调整机C3的滚动带动步进式料斗C38不断的做提升倒料运动，钢珠与需要调整的机制砂同时被提升到顶端，并同时下落，处于下部的反击式步进料斗本身材质为高锰钢，钢珠下落到反击表面时即可以击打反击面上的需要调整的机制砂，又可以经过反弹而击打相邻反击面上的机制砂，并且由于机制砂级配调整机C3的筒壁在不停的旋转，下部堆积的机制砂与钢珠的混合物不断的被击打，滚动磨削，又被下一级斗提提升到顶端而重复做下落，被击打，磨削，步进的工序，以此来降低机制砂的细度模数，并在滚动当中把机制砂的菱角磨去，使机制砂级配调整机C3既达到降低细度模数的作用，也达到了调整细小机制砂的粒型作用，使得调整之后的成品机制砂能达到天然砂的品质。钢珠可以是成品的钢筋切头也可以是建筑废弃的螺纹钢切头来制作，只要该切头具备一定质量，从高端落下后能够起到打击作用即可。机制砂级配调整机C3的动力采用变频调整转速，通过筒壁的不同转速来控制产成品的细度模数。
