Description

说 明 书 搅拌推进式卧式预混装置及其方法 技术领域
本发明涉及一种卧式预混装置， 特别涉及一种搅拌推进式卧式预混装置， 属于机械 混合设备领域。 '
本发明还涉及一种采用搅拌推进式卧式预混装置进行混合的预混方法。 背景技术
在复原米加工过程中，需要将谷物的固体粉末和水等液体进行均匀混合，得到粘度高 的固液混合物， 而上述固液混合物中， 又需要进一步均匀添加各种固体和 /或液体添加剂。 而上述各种物料需要均匀分布在所得固液混合物中，以使得制得的复原米的各物质含量符 合标准。
然而由于谷物的固体粉末颗粒较细、不能溶于水，且一旦与水混合，就会变成粘度高 的混合物。在生产中，将液体添加到固体粉末中进行混合、将固体粉末添加到液体中进行 混合、将液体和固体粉末同时添加进行混合时，不仅会产生部分固体粉末和液体粘成团状， 而剩余的谷物固体粉末和液体无法混合的情况，而且还会在液体中产生固体粉末的二次凝 聚颗粒， 即， 粉团， 该粉团外部是粉末与水的混合物， 而内部则是没有混合的固体粉末。 并且即便在混合过程中进行搅拌，在相当长的时间内，仍会混合不均勾，而已经产生的二 次凝聚再次分散到液体中十分困难。如果固体粉末和液体混合得到的固液混合物的粘度高 时， 上述现象更加显著， 均匀混合难度更大。
如果采用少量的固体粉末和液体进行搅拌混合， 虽然可以得到较为均匀的固液混合 物， 但是混合的速度较慢， 所得混合物较少， 无法满足大批量的工业化生产的需要。
基于日本专利申请 278598/202、 21188/2003 , 185502/2003 的中国专利申请
03164908.4中， 公开了一种搅拌混合装置及搅拌混合方法， 该装置包括一个近似圆筒状 的混合容器，其内部具有搅拌叶片，粉体和液体通过不同的入口进入混合容器，然后在搅 拌叶片的搅拌下，进行混合。搅拌叶片之间形成了分隔室，从而将粉体和液体分隔成若干 组进行混合，然而在实际混合过程中，无法良好的进行分组混合， 并且混合容器的内壁上 会存积又大量混合物， 无法被均匀搅拌。 PCT国际申请 PCT/US2003/011426中， 公开了一种混合设备， 该设备包括一个底 部充满液体的桶，一个插入液体中并且内部具有旋转叶片的竖直导管，固体粉末从该竖直 导管从上至下的添加之导管中具有液体的部分，并在搅拌叶片的作用下，和液体进行混合， 然后再分散到导管外侧的桶中和液体进行进一步的混合。然而该设备适用于将少量的固体 粉末分散到大量的液体中， 并且所得固液混合物不能具有较高粘度， 否则将会堵塞导管。
基于日本专利的中国专利申请 03122966.2中，公开了一种粉体和液体的混合装置及 其方法，该装置中粉体从混合容器的顶部发散落下，然后在下落过程中与容器四周喷射的 液体相互混合。虽然这种混合方法可以在一定程度上让粉体和液体进行分散混合，避免粉 团产生，然后并不是所有下落的粉体都可以和喷射的液体进行混合，未混合的粉体和液体 落到混合容器的底部， 仍不能进行均匀混合。 同时， 在该混合过程中，粉体和液体的物料 量、 混合配比都难以控制。
中国专利申请 200410084721.1 中， 公开了一种立式固液混合装置及混合方法， 该 装置包含一组沿着混合容器内壁设置的挡板，将混合容器划分成若干中空的搅拌室，然后 利用混合容器中央的一组搅拌叶片搅拌各搅拌室内的粉体和液体进行混合。然而由于水平 中空的搅拌室的存在， 从混合容器顶部投料的各物料将会大量积攒在上部的几个搅拌室 内，而导致各个搅拌室内物料分布的不均，同时如果粉体和液体的混合物具有较高粘度的 话，该混合物也将因各个挡板及搅拌室的存在而阻塞混合容器。同时单一的粉体添加入口， 会导致物料在混合容器的横截面上不能沿各个方向均匀分布。
同时中国专利 200610011506,8和欧洲专利 EP06113920.0分别公开了两种静态混合 装置，利用各物料的分流，进行混合，然而上述装置不适用于混合后粘度较高的粉体和液 体的混合。
同时中国专利 200410090534.4中， 公开了一种内部具有搅拌叶片的卧式混合装置， 粉体和液体分别从卧式混合装置的一侧的顶部和底部注入装置中，然后利用叶片进行搅拌 混合。虽然这种卧式混合装置可以解决在重力作用下，粉体及液体下落过快而导致混合装 置内物料分布不均的情况， 然而仍 I日难以解决粉体和液体均匀混合的问题。
除上述外， 中国专利 200510009386.3、 200510042674.9、 200510129550.4、 200510103613.9等也都公开了多种混合装置，然而上述装置仍旧未能解决混合后粘度高 的固体粉末和液体按一定配比进行均匀混合的技术问题。 发明内容 本发明的一个目的在于提供一种搅拌推进式卧式预混装置，通过该装置可以将固体粉 末和液体按一定配比进行均匀混合，特别适用于混合后粘度高的固体粉末和液体的均匀混 合。

所述的进料系统连接混合系统和高压气体喷射系统，并向其中输送固体物料和液体物 料。所述的进料系统包含位于转轴上的固体进料口、位于壳体上的气液进料口和添加剂进 料口。

本发明公开的一种采用卧式预混装置进行混合的预混方法， 包括如下步骤： 步骤 1 :从所述的气液进料口的各个进料口输入气体、液体或气液混合物进入卧式混 合反应釜内部。
由于所述的气液进料口的进料口数量与叶轮上的分隔板数量相等，并且每个气液进料 口与临近进料口的叶轮上的相应分隔板之间交错 0°〜45°夹角。故从各个进料口输入的气 体、液体或气液混合物在与该进料口相邻且相对应的分隔板与刮料板上流动，并依次沿着 各个分隔板和刮料板向下流经相对应地各个分隔板和刮料板，从而均勾的分布在各个分隔 混合室。
步骤 2: 从所述的固体进料口的各个进料口输入混合有固体粉末的高压气体进入轴 腔， 然后通过轴壳上的开口向外单向喷射。
由于每两个相邻叶轮间的轴腔区域具有一组所述开口，该组开口的数量为一个叶轮上 的分隔板数量的整倍数，并且所述开口分布在轴腔连接有分隔板的区域上。故混合有固体 粉末的高压气体可以通过各个开口喷射在各个相应分隔板上流动的液体或固液混合物上， 从而均匀的分布在各个分隔混合室。
步骤 3: 从所述的添加剂进料口的各个进料口输入混合有固体粉末、液体液滴、气体 等添加剂的高压气体进入轴腔， 然后通过轴壳上的开口向外单向喷射。
由于每两个相邻叶轮间的轴腔区域具有一组所述开口，该组开口的数量为一个叶轮上 的分隔板数量的整倍数，并且所述开口分布在轴腔连接有分隔板的区域上。故混合有固体 粉末、液体液滴、气体等添加剂的高压气体可以通过各个开口喷射在各个相应分隔板上流 动的液体或固液混合物上， 从而均匀的分布在各个分隔混合室。
步骤 4: 转轴带动其上连接的一组叶轮以转轴为圆心进行旋转， 利用各个叶轮上的 分隔板对混合着的固体粉末和液体的混合物进行搅拌， 以充分混合， 同时利用各个刮料 板将粘附在壳体内壁上的物料刮除， 以使得上述物料再次进行搅拌混合。
步骤 5:经过混合的固体粉末、液体与添加剂的混合物沿着各个分隔板逐级流下至下 一层分隔混合室， 继续进行搅拌混合。
所述推进系统的推进杆在壳体底部内表面的凹槽中前后移动，从而带动其上连接的各 推进器前后移动。
在推进杆向前移动的时候， 各推进器的正面将混合物向前推进。
在推进杆向后移动的时候，各推进器的反面将混合物分流，以避免将混合物反向带回。 步骤 6:与存料室相邻的最后一级分隔混合室内的混合物沿着各个分隔板流入相应的 存料室 106， 然后通过相应的出料口 105向外输出。
由于存料室 106的数量和分隔板数量相等， 而且每个存料室 106相应的具有一个出 料口 105，所以从所述混合反应釜中可同时输出多批混合物， 以分别进行相同或不同的进 一步加工。
利用上述装置及方法， 从各个气液进料口 1042同时输入多批气液物料， 并分别沿着 叶轮组上的各个相应的分隔板和刮料板流下并均匀分布在各个分隔混合室内。同时从转轴 103上的各个开口 1033喷出含有固体粉末和 /或添加剂的高压气体， 以使得固体粉末和 / 或添加剂均勾喷射在各个分隔板上。通过上述操作，液体物料被分散成多批， 固体粉末和 /或添加剂被分散的喷射出与各批液体物料相互混合， 从而使得液体、 固体粉末、 添加剂 以分散的方式进行相互混合。这种分散混合的方式，有效的避免了局部固体粉末集中、液 体分布不均等所带来的混合过程中的二次凝聚颗粒现象，即粉团现象。同时由于液体逐渐 输入并沿分隔板留下，而固体粉末持续喷射，故对于一部分液体而言， 从输入混合反应釜 开始，逐渐与若干批固体粉末混合，也就是相当于将一定量的液体先和少量的固体粉末混 合， 以避免固体粉末过于集中而导致的混合不均勾，然后向所得均匀混合物中再添加少量 固体粉末混合， 同样也避免了混合不均匀， 这样， 逐渐的添加多批少量固体粉末， 带最初 输入的一定量的液体从第一级分隔板流下至最后一级分隔板时，已经均匀的混有大量的固 体粉末， 得到均匀的固液混合物。上述方法实质上是将大量液体、大量固体粉末、大量添 加剂在混合反应釜中利用本发明特有的结构进行了多重分散， 以使得液体、固体粉末、添 加剂以分散的、少量的形式进行充分的、逐渐的均匀混合， 同时也避免了少量、逐渐混合 用时较长且无法大批量化生产的缺点。除此之外，本发明可以直接同时分批输入固液混合 物，以同时供多条生产线进行进一步加工，而不需要额外的装置对混合物进行分流。同时， 各相邻叶轮的分隔板之间交错一定角度可以使得液体及混合物可以缓慢沿着分隔板流向 下一个分隔室， 以使得固液接触时间增长，而分隔板与平面成一定的夹角有利于粘度高的 固液混合物的流动和传输。 同时推进系统也促进了具有一定粘稠度的混合物向前移动。
通过上述装置和方法，本发明利用多重分散有效的避免了固体粉末和液体混合过程中 存在的各种问题， 可以快速、持续、稳定的以一定配比对液体、 固体粉末、添加剂进行均 勾的混合。 附图说明 图 1是本发明的卧式预混装置的整体结构视图。

根据图 1 :
所述的出料系统 1050连接位于混合系统 1010底部的存料系统 1060，并从其中输出 混合物料。 所述的存料系统 1060具有与其相邻的叶轮 10202上分隔板数量相等的存料 室 106， 每个存料室 106相应的具有一个出料口 105， 所述的各个出料口 105组成所述 的出料系统 1050。
一种采用卧式预混装置进行混合的预混方法包括如下步骤- 根据图 1、 图 2、 图 7:
步骤 1 : 从所述的气液进料口 1042的各个进料口输入气体、 液体或气液混合物进入 卧式混合反应釜内部。
由于所述的气液进料口 1042的进料口数量与叶轮上的分隔板数量相等，并且每个气 液进料口 1042与临近进料口的叶轮 10201上的相应分隔板之间交错 0°〜45°夹角。故从 各个进料口输入的气体、液体或气液混合物在与该进料口相邻且相对应的分隔板与刮料板 上流动，并依次沿着各个分隔板和刮料板向下流经相对应地各个分隔板和刮料板，从而均 匀的分布在各个分隔混合室。
根据图 2、 图 4、 图 3、 图 5、 图 7:
步骤 2: 从所述的固体进料口 1041的各个进料口输入混合有固体粉末的高压气体进 入轴腔 1031， 然后通过轴壳 1032上的开口 1033向外单向喷射。
由于每两个相邻叶轮间的轴腔 1031 区域具有一组所述开口 1033， 该组开口的数量 为一个叶轮上的分隔板数量的整倍数， 并且所述开口 1033分布在轴腔 1031连接有分隔 板 1021的区域上。 故混合有固体粉末的高压气体可以通过各个开口 1033喷射在各个相 应分隔板上流动的液体或固液混合物上， 从而均匀的分布在各个分隔混合室。
根据图 2、 图 4、 图 3、 图 5、 图 7:
步骤 3:从所述的添加剂进料口 1043的各个进料口输入混合有固体粉末、液体液滴、 气体等添加剂的高压气体进入轴腔 1031，然后通过轴壳 1032上的开口 1033向外单向喷 射。 由于每两个相邻叶轮间的轴腔 1031 区域具有一组所述开口 1033， 该组开口的数量 为一个叶轮上的分隔板数量的整倍数， 并且所述开口 1033分布在轴腔 1031连接有分隔 板 1021的区域上。 故混合有固体粉末、液体液滴、气体等添加剂的高压气体可以通过各 个开口 1033喷射在各个相应分隔板上流动的液体或固液混合物上，从而均匀的分布在各 个分隔混合室。
根据图 1、 图 2、 图 3a、 3e:
步骤 4: 转轴 103带动其上连接的一组叶轮以转轴 103为圆心进行旋转， 利用各个 叶轮 102上的分隔板 1021对混合着的固体粉末和液体的混合物进行搅拌，以充分混合， 同时利用各个刮料板 1022将粘附在壳体 101内壁上的物料刮除， 以使得上述物料再次 进行搅拌混合。
根据图 1、 图 2、 图 3a、 3b、 3c、 3d、 3e:
步骤 5: 经过混合的固体粉末、 液体与添加剂的混合物沿着各个分隔板 1021逐级流 下至下一层分隔混合室， 继续进行搅拌混合。
由于所述的每一个叶轮的分隔板与其相邻叶轮的分隔板之间交错 0°〜45°夹角，经过 混合的固体粉末、 液体与添加剂的混合物沿着图 3a的分隔板 1021 依次逐级落至图 3b 的分隔板 1021上、 图 3c的分隔板 1021上、 图 3d的分隔板 1021上。
由于分隔板 1021与竖直面成 0°〜30°夹角， 便于上述混合的固体粉末、 液体与添加 剂的混合物流向下一级分隔板 1021。
根据图 1、 图 8a〜8f、 图 9a〜9c:
所述推进系统 1000的推进杆 1005在外界电机带动下在壳体 101底部内表面的凹槽 1012中前后移动， 从而带动其上连接的各推进器 100前后移动。
在推进杆 1005向前移动的时候， 各推进器 100的正面 1003将混合物向前推进。 在推进杆 1005向后移动的时候， 各推进器 100的反面 1004将混合物分流， 以避免 将混合物反向带回。
根据图 1 :
步骤 6:与存料室 106相邻的最后一级分隔混合室内的混合物沿着各个分隔板流入相 应的存料室 106， 然后通过相应的出料口 105向外输出。
由于存料室 106的数量和分隔板数量相等， 而且每个存料室 106相应的具有一个出 料口 105，所以从所述混合反应釜中可同时输出多批混合物， 以分别进行相同或不同的进 一步加工。 实施例二：
