Description

一种干法研磨与整形的节能型双轴承立式研磨机 技术领域
本发明涉及立式研磨机的技术领域，特别是一种干法研磨与整形的节能型双轴承立式研磨机。
背景技术
工业磨机是传统工业基础设备，广泛应用于矿山、电力、钢铁、水泥、陶瓷等行业，量大面广，设备庞大，消耗大量能源。自1882年丹麦史密斯公司生产水泥管磨机以来，工业用管磨机没有根本性的改进。传统工业现在使用的工业管磨机存在效率低下，能耗利用率只有
Figure PCTCN2021095462-appb-000001
的水平，95％以上的电能转化为废热和噪音。
现在粉磨水泥等干法粉体的工艺设备，无论是辊压机(辊式立磨)联合管磨机还是辊式立磨系统都有缺陷，一是投资高，二是运转率低，三是运行费用高，四是电耗高，五是噪音大，六是产品重金属污染严重，七特别是粉磨水泥产品的颗粒形貌(球形度、长径比)差，影响最终混凝土产品的工作性能、密实度、耐久性，是一项世界性难题。
再者，现有的研磨机大多采用湿法研磨，因此大多采用变频电机+减速机+单轴承结构，其具备以下缺点：
第一，此结构的转子不仅振动大，而且转子的制造要求高，特别是在转子振动大时需要降低转子转速，进而大大降低了研磨效率；
第二，采用变频电机+减速机需要搭配特种联轴器(大于630kw的特种联轴器是只有欧洲公司能生产，属于卡脖子设备)，目前国内需进口，因此立式研磨机的制造周期增加4-6个月；
第三，现在检修时，需要将转子取出，重量大，移出磨机困难，耗时费力。
有鉴于此，本发明人专门设计了一种干法研磨与整形的节能型双轴承立式研磨机，本案由此产生。
发明内容
为了解决上述问题，本发明的技术方案如下：
一种干法研磨与整形的节能型双轴承立式研磨机，包括竖直设置的壳体、设置于壳体上方/下方的永磁变频电机、与永磁变频电机输出端连接的转轴、设置于转轴上的双螺旋转子，所述壳体内部设置研磨腔，所述研磨腔顶部与底部分别设置上轴承与下轴承，所述上轴承与下轴承均套设于转轴上，且位于转轴的上下两端，所述上轴承、下轴承均与转轴转动连接；
所述研磨腔内部填充研磨介质，所述壳体侧壁的上端/上端面设置与研磨腔内部连通的进 料口与收尘口，其侧壁下端/下端面至少设置两个与研磨腔内部连通的卸料口，所述壳体下端面设置于研磨腔内部连通的鼓风口。
进一步的，所述壳体侧壁至少设置一个开口，且开口处均设置检修门；优选设置两个检修门，可同时作业，提高工作效率，特别是在检修时，无需将双螺旋转子取出。
进一步的，所述壳体内侧壁与检修门侧壁分别设置第一衬板与第二衬板，所述第一衬板与第二衬板形成所述研磨腔。
进一步的，所述第一衬板、第二衬板以及研磨介质均采用刚玉材质。
进一步的，所述上轴承、下轴承采用滚动轴承。
进一步的，所述双螺旋转子包括沿着转轴中心轴方向向下且朝向两个不同方向螺旋的螺旋板、设置于螺旋板的若干块螺旋衬板；所述螺旋衬板为组合式，且采用刚玉材质。
进一步的，所述卸料口处设置卸料篦子，所述卸料篦子设置若干并排设置等间距的水平间隙，所述水平间隙在2-6mm之间。
进一步的，所述进料口连接计量输送装置；所述卸料口连接卸料控制装置。
进一步的，所述卸料控制装置包括螺旋闸板、气动闸板、电动流量阀及计量装置。
进一步的，所述收尘口与收尘器连接；所述鼓风口与壳体连接处设置若干小的通风口，且鼓风口与鼓风装置连接。
进一步的，若干所述通风口等间距排布呈环形状或圆形状；当永磁变频电机设置于壳体上方时，若干通风口呈环形状或圆形状；当永磁变频电机设置于壳体下方时，若干通风口呈圆形状。
进一步的，所述壳体下方设置基础；所述基础呈圆柱状，且地面以上为中空，所述基础侧面设置检修口；当永磁变频电机设置于壳体下方时，其固定于基础上。
本发明的立式研磨机通过在转轴的上下两端分别套设上轴承与下轴承，因此可降低双螺旋转子的振动与制造要求，同时可提高转速配合双螺旋转子以提高研磨效率，且采用了双轴承结构，无需采用进口的特殊联轴器(大于630kw的特种联轴器是只有欧洲公司能生产，属于卡脖子设备)，只需普通联轴器即可，因此立式研磨机的制造周期缩短4-6个月；传动结构简单，传动效率提高，降低噪音，减少减速机润滑油站和冷却水的使用，减少自然资源消耗，有益于建立环境友好型社会。

请参阅图1至9，是作为本发明实施例1的一种干法研磨与整形的节能型双轴承立式研磨机，包括竖直设置的壳体10、设置于壳体10上方的永磁变频电机20、与永磁变频电机20输出端连接的转轴30、设置于转轴30上的双螺旋转子40，其中，采用双轴承结构，无需采用进口的特殊联轴器，只需普通联轴器即可，因此立式研磨机的制造周期缩短4-6个月，且采用双螺旋转子40可以降低单螺旋转子存在的盲区，且提高研磨的稳定性；壳体10内部设置研磨腔，研磨腔顶部与底部分别设置上轴承50与下轴承60，上轴承50与下轴承60均套设于转轴30上，且位于转轴30的上下两端，且上轴承50、下轴承均60与转轴30转动连接，因此可降低双螺旋转子40的振动，转子的制造要求降低，同时可增加转速配合双螺旋转子40以提高研磨效率；具体的，本发明上轴承50、下轴承60采用滚动轴承，且本发明的上轴承50与下轴承60上均设置密封结构，起到对两轴承的保护作用，防止粉尘进入，提高使用寿命。
研磨腔内部填充研磨介质，壳体10侧壁的上端/上端面设置与研磨腔内部连通的进料口11与收尘口12，其侧壁下端/下端面至少设置两个与研磨腔内部连通的卸料口13，壳体10下端面设置于研磨腔内部连通的鼓风口14，由于本发明采用提高研磨效率的双轴承结构，因此优选的设置两个相互对称的卸料口13，以提高卸料能力。
壳体10侧壁设置至少设置一个开口15，且开口15处均设置检修门70，优选设置两个检修门70，可同时作业，提高工作效率，特别是在检修时，无需将双螺旋转子40取出；壳体10内侧壁与检修门70侧壁分别设置第一衬板16与第二衬板71，第一衬板16与第二衬板71形成研磨腔。
第一衬板16、第二衬板71以及研磨介质均采用刚玉材质；双螺旋转子40包括沿着转轴30中心轴方向向下且朝向两个不同方向螺旋的螺旋板41、设置于螺旋板41的若干块螺旋衬板42；螺旋衬板42为组合式，且采用刚玉材质；其中刚玉材质为非金属材质，可避免研磨后的产品重金属超标
卸料口13处设置卸料篦子80，卸料篦子80设置若干并排设置等间距的水平间隙81，水平间隙81在2-6mm之间，卸料篦子80实现研磨后的物料快速排出，并防止研磨介质排出。
进料口11连接计量输送装置；卸料口13连接卸料控制装置，卸料控制装置包括螺旋闸板、气动闸板、电动流量阀及计量装置，且螺旋闸板用于检修时可手动打开。
收尘口12与收尘器连接，便于将研磨过程中研磨腔内产生的粉尘与热量通过收尘器进行处理，符合环保要求；鼓风口14与壳体10连接处设置若干小的通风口，小的通风口防止研磨后的物料与研磨介质排出，同时便于鼓风，具体参阅图5-图8，若干通风口等间距排布呈环形状或圆形状，本实施例中的永磁变频电机20设置于壳体10上方，若干通风口呈环形状或圆形状；且鼓风口14与鼓风装置连接，在研磨过程中通入气体，将研磨腔中的粉尘以及产生的热量能够及时有效排出，同时保证物料出料更加顺畅，提高研磨效率。
壳体10下方设置基础90；基础90呈圆柱状，且地面以上为中空，基础90侧面设置检修口91；同时可在壳体10下端面设置卸出研磨介质的通孔，便于将研磨介质排出更换。
实施例2
请参阅图10，是作为本发明实施例1的一种干法研磨与整形的节能型双轴承立式研磨机，该实施例与实施例1的区别在于永磁变频电机20设置于壳体10下方，永磁变频电机20直接固定设置于基础90上，且为了便于检修与安装，检修口91根据永磁变频电机20的大小进行优化调整，对应的若干通风口呈圆形状设置。
本发明的立式研磨机用于水泥等粉体或者机制砂等颗粒的干法研磨与整形，通过在壳体10侧壁上端或上端面设置进料口11，其侧壁下端或下端面设置卸料口13，实现需要研磨的 物料从上端进料，下端卸料，并在壳体10下端面设置鼓风口14便于鼓入空气，将研磨过程中的粉尘以及产生的热量能够及时有效排出，同时保证物料卸料更加顺畅，配合双轴承结构降低了双螺旋转子40的振动，提高研磨效率。
本发明节能型双轴承立式研磨机具备的优点如下：
第一，单轴承支撑改为双轴承支撑，其一是改善转子轴承受力状况，减小转子振动，整个设备的振动减小，动载荷系数减小，研磨机及设备转子制造要求降低；其二是对轴承受力状况大幅改善，可以节约成本30％以上，使用寿命延长1倍，功率消耗降低5％；其三是联轴器的受力状况得到大幅改善，不再需要特种联轴器(大于630kw的特种联轴器是只有欧洲公司能生产，属于卡脖子设备)，使用国内一般联轴器就可以解决，降低成本50％，缩短制造运输周期6个月，可以早半年建成工厂，经济效益可观，具体的，以50吨/小时的立式研磨机为例，按每天24小时生产，每吨产品的附加值为40元，总经济效益约为：50吨/小时*24小时*30天/月*6月*40元/吨＝8640000元(理论测算值)；
第二，传动装置改进，将永磁变频电机替代变频电机+减速机，传动结构简单，传动效率提高，降低噪音，减少减速机润滑油站和冷却水的使用，减少自然资源消耗，有益于建立环境友好型社会；
第三，研磨机筒体高径比降低，由原来的1.5左右降低至1.0左右，改善受力情况、减小震动、降低制造成本等，具体的，其他条件一致情况下，采用单轴承支撑时，M 1＝FL 1，采用双轴承支撑时，M 2＝F1/2L 1＝1/2M 1。
综上所述，本发明的立式研磨机通过在转轴的上下两端分别套设上轴承与下轴承，因此可降低双螺旋转子的振动与制造要求，同时可提高转速配合双螺旋转子以提高研磨效率，且采用了双轴承结构，无需采用进口的特殊联轴器，只需普通联轴器即可，因此立式研磨机的制造周期缩短4-6个月；传动结构简单，传动效率提高，降低噪音，减少减速机润滑油站和冷却水的使用，减少自然资源消耗，有益于建立环境友好型社会。
上面结合附图对本发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进，或未经改进将本发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围之内。
