After the fabric in each laundry basket is washed for a set time, it is conveyed to the next laundry basket at the same time, that is, it is advanced once from the first bin to the last bin. After leaving the last bin, it enters the press for dehydration. Fabric washing and squeezing dehydration are carried out at the same time.

Description

一种洗衣龙 技术领域
本发明涉及洗衣技术领域，特别涉及一种洗衣龙。
背景技术
隧道式洗衣机系列简称为“洗衣龙”，与传统洗衣机相比，该设备采用了水循环和过滤技术，极大降低了水消耗和蒸汽消耗；可节水50％、节电40％以上，节省人力60％。洗衣龙性能优越，具有极高的可靠性。底部传输的设计布草更能实现安全、可靠的传输。单双滚筒结合，高强的拨打筋，传送和洗涤仓容采用最佳配比设计，造就其强大的洗涤机械作用力和洗净度。同时洗衣龙只在有需要加洗涤剂的地方采用双滚筒设计，如加热和漂洗。减少了机械件的数量和维修工作量。洗涤原理为：洗衣龙各仓同时洗涤，每一个仓段可以根据电脑的不同指令可以按照预洗、主洗、漂洗、中和等程序进行工作。同时传送，每一个洗衣转笼内的织物经过设定的时间洗涤后，同时向下一节洗衣笼传送，即第一仓到最后一仓一次推进。最后一仓出仓后进入压榨机脱水。织物洗涤与压榨脱水同时进行。被洗织物被送入第一仓与最后一仓出仓进入压干机同时进行。脱水后的织物被送到烘干机烘干。洗涤采用圆周摆动方式(晃动方式)。洗衣龙既要洗涤也要承担仓与仓之间的传送功能，洗涤方法与洗脱机360°转动洗涤不同，而是滚筒沿圆周方向正传反转摆动方式进行。摆动(晃动)角度在180°～285°之间旋转传送方式。洗衣龙采用螺旋传送设计。洗衣转笼旋转360°可以通过螺旋曲面把本仓织物传送到下一仓继续洗涤。传送方式分为：上传(顶部传送)和下传(底部传送)。洗衣仓越多，其小时洗涤量越大，一般洗衣龙仓数为8-16仓，每仓额定装载量为25-100公斤。
但是，现有技术中，洗衣龙一般需要大量的清水和洗涤剂来对草布进行清洗，清洗后产生大量的废水，对环境造成污染。解决环境污染的问题需要投入排污系统，排污系统一般的占地面积大，随着厂房租金和土地成本的上升，排污系统明显增加了生产成本，尤其是洗衣龙数量多的情况下，排污系统的占地面积更加会随着产能的提升而显著增加，例如沉淀池的面积要加大，其他不同的化学反应池也需要增加容积来满足排污系统的需求，进一步推高了生产成本。如果没有有效的排污系统，则违反环保相关的法律法规。针对洗涤行业排污系统占地大的问题，跨国公司MILNDR充分利用了膜技术中的功能陶瓷膜(Ceramic Membranes)来对污水进行过滤。ECOLAB则利用了磁盘过滤(Disk Filtration)的方式来对污水进行过滤。AQUARECYCLE则利用碳吸附(Carbon Absorption)的原理来对污水进行过滤。这些跨国具体对于洗涤废水的过滤方式方法都是非常成功有效的。遗憾的是，无论是功能陶瓷膜、磁盘过滤还是碳吸附，都需要定期更换过滤组件来满足排污达标的要求。跨国企业在收取较高的服务费用的情况下，能够承担高昂的过滤组件更换费用。另一边厢，普通的企业对于高昂的过滤组件更换费用，会造成好大的成本上涨，影响到他们的经营压力和利润空间。此外，现在的洗衣龙还存在着在回用水的时候，把污染物含量、化料最多、最脏的主洗水与漂洗水或清水混合在一起回用，希望通过稀释的方式去降低污染物含量，但是没有把最脏的水排 出去，导致了污染物依然一直循环在洗衣龙的回用水内，起到了反作用；在最后的中和过程中，现在的洗衣龙把漂洗水和中和水再次混在一起回用，在水不足的时候才补清水，这样的循环不能保证在中和过程中有完全干净、新鲜的水，污染物依然难以降低。所以洗衣龙洗涤系统经常出现了洗涤后过水不清令布草发黄、发灰，造成布草的使用寿命降低的情况。

更优选的，所述第十四洗涤仓通过接通位于其下方的第三排水口的第三排水管连接第二水箱；所述第二水箱设有第二出水口，所述第二出水口与所述第八洗涤仓的进水口连通。

本发明的有益效果如下：
采用上述技术方案，由于主洗机构的洗涤仓的排水口连接与桌布预洗装置和主洗装置而漂洗机构的排水口连接第一水箱的进水口，并且通过第一水箱连接预洗机构的第一洗涤仓的进水口，使得经过主洗工序后的废水可以分流到不同洗涤工序或洗涤对象中循环再用。其中，分流到预洗机构中的第一洗涤仓的循环用水可以在第一洗涤仓中对需要洗涤的草布进行预洗，降低预洗阶段所需的化学洗涤材料。而分流到桌布预洗装置和主洗装置的循环用水则节省了预洗和主洗桌布时所需的化学洗涤材料。在废水循环的角度考虑，因为在洗衣龙洗涤草布后的废水部分分流到预洗机构中的第一洗涤仓中循环再用，部分用于其他洗涤设备中进行洗涤桌布，降低了需要排污的污水量，从而降低的排污成本和排污设备的占地面积。
再者，由于连接桌布洗涤装置中的桌布预洗装置和主洗装置漂洗机构的第一排水管和连接漂洗机构的排水口与第一水箱的进水口之间的第二排水管同时进入热交换器中，通过热交换使得第一排水管中的循环用水温度降低，而第二排水管中的循环水的温度上升，满足预洗草布的水温要求，并因此大大省却了预洗时加入升温后的清水和化学洗涤料的需求。草布在预洗阶段就加入了漂洗后排出的循环用水，有效增加了洗涤效果。
另外，通过水箱和管道的连接，从中和机构中的第十四洗涤仓流出来的漂洗水先流向第二水箱进行收集再流入主洗机构中的第八洗涤仓，为从第八洗涤仓进入漂洗机构中的第九洗涤仓的草布进行预漂洗，降低漂洗工序所需的漂洗用化学料。
此外，从中和机构中的最后一个洗涤仓流出来的中和后水先流向第三水箱进行收集再流入漂洗机构中的最后一个洗涤仓，降低漂洗废水的浓度，从而降低中和工序时所需要添加清水的容积，更有利于环保。
还有，第十三洗涤仓为最后一个漂洗仓，并且有逆流装置，把第十三洗涤仓的漂洗水逐仓逆流到第九洗涤仓，一共经过了五个仓及十多分钟，使水中的中和物质得到充分的发挥，也能降低中和工序所要添加的清水容积以及中和化料。

图1为本发明的系统图。
具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
为解决现有技术纯在的问题，如图1所示，本发明的一种实施方式提供：
一种洗衣龙，包括：
预洗机构，由分别为第一洗涤仓和第二洗涤仓的2个洗涤仓组成；第一洗涤仓的进水口与水处理后的回用水第一供水管连通；第一供水管的回用水的PH值、重量和温度分别为：PH8.3-9、4.5Kg和42-54℃；该温度和酸碱度有利于草布的预洗。
主洗机构，由分别为第三洗涤仓、第四洗涤仓、第五洗涤仓、第六洗涤仓、第七洗涤仓和第八洗涤仓的6个洗涤仓组成；第三洗涤仓和第四洗点仓与加热管道连通；第八洗涤仓设有第一排水口，第一排水口连接与桌布预主洗装置的进水口连通的第一排水管；
漂洗机构，由分别为第九洗涤仓、第十洗涤仓、第十一洗涤仓、第十二洗涤仓和第十三洗涤仓的5个洗涤仓组成；第九洗涤仓设有第二排水口，第二排水口与第一水箱或过滤装置通过第二排水管连接；第一水箱设有第一出口，第一出口与回用水第一供水管连通；
中和机构，由分别为第十四洗涤仓、第十五洗涤仓和第十六洗涤仓的3个洗涤仓组成；第十四洗涤仓设有清水供水管，清水供水管连接清水水龙头。
具体的，第二排水口与第一水箱通过第二排水管连接；第一排水管和第二排水管经过热交换器，使第一排水管的热量散失至第二排水管。采用上述技术方案，由于主洗机构的洗涤仓的排水口连接与桌布预洗装置和主洗装置而漂洗机构的排水口连接第一水箱的进水口，并且通过第一水箱连接预洗机构的第一洗涤仓的进水口，使得经过主洗工序后的废水可以分流到不同洗涤工序或洗涤对象中循环再用。其中，分流到预洗机构中的第一洗涤仓的循环用水可以在第一洗涤仓中对需要洗涤的草布进行预洗，降低预洗阶段所需的化学洗涤材料。而分流到桌布预洗装置和主洗装置的循环用水则节省了预洗和主洗桌布时所需的化学洗涤材料。在废水循环的角度考虑，因为在洗衣龙洗涤草布后的废水部分分流到预洗机构中的第一洗涤仓中循环再用，部分用于其他洗涤设备中进行洗涤桌布，降低了需要排污的污水量，从而降低的排污成本和排污设备的占地面积。
再者，由于连接桌布洗涤装置中的桌布预洗装置和主洗装置漂洗机构的第一排水管和连接漂洗机构的排水口与第一水箱的进水口之间的第二排水管同时进入热交换器中，通过热交换使得第一排水管中的循环用水温度降低，而第二排水管中的循环水的温度上升，满足预洗草布和台布的水温要求，并因此大大省却了预洗时加入蒸汽升温和减少化学洗涤料的需求。草布在预洗阶段就加入了漂洗后排出的循环用水，有效增加了洗涤效果。
在上述基础上，本发明另外一种实施方式为：
第十四洗涤仓通过接通第三排水口的第三排水管连接第二水箱；第二水箱设有第二出水 口，第二出水口与第八洗涤仓的进水口连通。
具体的，第八洗涤仓的进水口连接第二供水管。
具体的，第十六洗涤仓设有第四排水口，第四排水口通过第四排水管连接第三水箱的进水口，第三水箱还与压机连接。
更具体的，第三水箱设有第三出水口，第三出水口通过第三供水管与第十三洗涤仓的进水口连接，第三水箱还设有与第二水箱连接连通的第四供水管，以使第二水箱的回收水可进入第三水箱进行混合。
具体的，第一水箱设有第二出口，第二出口与桌布过水装置的进水口连通。
在上述基础上，本发明还有一种实施方式为：
流经第二供水管、第三供水管和清水管的水的PH值、重量和温度分别为：PH6-7，3Kg和42-52℃、PH6-7，5.5Kg和40-50℃以及PH，5.5Kg和40-45℃。

通过水箱和管道的连接，从中和机构中的第十四洗涤仓流出来的漂洗水先流向第二水箱进行收集再流入主洗机构中的第八洗涤仓，为从第八洗涤仓进入漂洗机构中的第九洗涤仓的草布进行预漂洗，降低漂洗工序所需的漂洗用化学料。由于第八、九仓是连接的双仓布置，可以快速排出污染物。
此外，从中和机构中的最后一个洗涤仓流出来的中和后水先流向第三水箱进行收集再流入漂洗机构中的最后一个洗涤仓，降低漂洗废水的浓度，从而降低中和工序时所需要添加清水的容积，更有利于环保。

具体的，第一水箱设有第二出口，第二出口与桌布过水装置的进水口连通。
洗涤工序包括预洗工序、主洗工序、漂洗工序和中和工序：
预洗工序在第一洗涤仓和第二洗涤仓中进行；
主洗工序在第三洗涤仓至第八洗涤仓中进行，其中第三和第四洗涤仓对草布进行加热，第五至第八洗涤仓对草布进行保温；
