摘要： The present invention relates to a secure landfill and to a method of operating a hazardous waste secure landfill characterized by a substantial reduction in the amount of leachate. The amount of leachate is minimized by maintaining a substantial amount of the atmospheric moisture collected within the confines of the fill separate from the waste material in the fill and removing such uncontaminated moisture from the fill site in an uncontaminated condition. The present landfill arrangement also facilitates the progressive incremental closing and permanent sealing of portions of the landfill while the remainder of the fill remains in active use.
摘要翻译：本发明涉及一种安全的垃圾填埋场和一种操作危险废物安全填埋场的方法，其特征在于大量减少渗滤液的量。通过将填充的范围内收集的大部分大气水分与填充物中的废物分开并将其从未填充的位置中除去未受污染的水分，从而将渗滤液的量减至最小。目前的垃圾填埋设施还有助于逐渐增加关闭和永久密封垃圾填埋场的一部分，同时剩余的填充物仍然积极使用。

摘要： This relates to a barrel or drum scraper to facilitate the complete emptying of a barrel or drum. Barrels and drums which are filled with a liquid containing solids and the like frequently have the solids settle out and become deposited on the inner surface of the barrel wall and the barrel bottom. Thus when you pour out the liquid content of a barrel filled with such a product, there remains in the barrel the solids which have adhered to the body and bottom. This relates to a scraper and barrel handler which will effect the removal of the solids from the walls of the barrel. This is particularly true when the barrel is used to store contaminated materials. In one form, the apparatus includes a barrel support which accurately positions the barrel, after which the scraper assembly moves down into the barrel. The scraper assembly includes a cylindrical scraper and a stirrer which is generally in the form of a cookie cutter which first cuts the deposit on the bottom of a barrel into segments and is then rotated so as to loosen all of this sediment. In another form of the apparatus, the barrel is clamped to a barrel support then the barrel is inverted to pour out what will flow out of the barrel, after which the inverted barrel is engaged by the bottom thereof in bottom supporting relation and pushed down over a combined fixed cylindrical scraper and stirrer with there being drive means for the scraper assembly.
摘要翻译：这涉及桶或滚筒刮刀以便于完全排空桶或桶。填充有含有固体等的液体的桶和桶经常使固体沉淀并沉积在桶壁和桶底部的内表面上。因此，当您倒出装有这种产品的桶的液体内容物时，在桶中仍然存在附着在机体和底部的固体。这涉及一种刮刀和桶处理器，其将实现从桶的壁移除固体。当桶用于储存受污染的材料时尤其如此。在一种形式中，该装置包括一个准确定位枪管的枪管支架，之后刮刀组件向下移动到枪管内。刮刀组件包括圆柱形刮刀和搅拌器，该搅拌器通常为饼干切割器的形式，其首先将桶的底部上的沉积物切割成段，然后旋转以便松开所有这些沉淀物。在该装置的另一种形式中，筒体被夹紧到筒体支撑件上，然后将筒体倒置以倒出将从筒体流出的物体，之后倒置的筒体由底部的底部支撑关系接合并向下推组合固定圆柱形刮刀和搅拌器，其中具有用于刮刀组件的驱动装置。

摘要： An apparatus for removing material from a drum or barrel includes a conveyor for transporting drums one at a time through an emptying station at which a housing having an open end is arranged for sealing engagement with an annular rim of a drum bounding an opening through which material is to be withdrawn. The emptying station additionally includes a mechanism adapted to lift drums from the conveyor and place same in sealing engagement with the housing, a scraper supported to movably project from within the housing through its open end and into the opening of a sealingly engaged drum for scraping material from the walls thereof and conveying such material outwardly of the drum into the housing for subsequent discharge therefrom through a discharge opening. The discharge opening communicates with an inlet opening of an axially elongated material conveyor serving to transport material from its inlet opening to a discharge opening removably communicating with a material receiver. The housing is fixed to the material conveyor and the material conveyor is supported for rotary movement about a horizontally disposed axis, whereby to effect vertical tilting of the sealing engaged drum and facilitate movement of material therefrom and through the housing into the material conveyor and subsequent discharge of material therefrom into the material receiver.
摘要翻译：一种用于从滚筒或桶中去除材料的装置包括一个输送机，用于一次一个地输送鼓，通过一个排空站，在这个排空工位上设有一个具有开口端的壳体，用于与限定一个开口的滚筒的环形边缘密封接合，将被撤回。排空站还包括适于从输送机提升鼓并将其设置为与壳体密封接合的机构，刮板被支撑以从壳体内通过其开口端可移动地突出并进入用于刮擦材料的密封接合的滚筒的开口中从其壁上将这种材料从滚筒向外输送到壳体中，以便随后通过排放口排出。排出口与轴向细长的材料输送机的入口开口连通，用于将材料从其入口开口输送到与材料接收器可拆卸地连通的排放口。壳体被固定到材料输送机上，并且材料输送器被支撑用于围绕水平设置的轴线的旋转运动，从而实现密封接合滚筒的垂直倾斜，并且便于材料从其中移动并通过壳体进入材料输送机并且随后的排出的材料从其进入材料接收器。
