一、用途及工作原理

I. Purpose and Working Principle

本機用于金礦石的氰化浸出鋅粉質換提金工藝中，是氰化浸出后的礦漿進行固液分離洗滌作業的專用設備，并可用于鈾礦水冶、輕工、化工、環保工業的脫水作業。它具有占地面積小，節省能耗、簡化工藝配置、減少輔助設備操作方便等特點。

        This equipment is designed for solid-liquid  separation washing operation for slurry after cyanide leaching during zinc  powder-gold extraction metasomatism through cyanide leaching of gold ore, and  can also be used for dewatering operations in hydro metallurgy of uranium ore,  light industry, chemical industry and environmental industry. This equipment  features space-saving footprint, low energy consumption, simplified process  configuration, reduction in auxiliary equipment and convenient operation etc.

NSL-66型試驗室濃縮機是采用濕式選礦的選后產品（礦漿）進行脫水的一種設備，由濃縮池和機械刮泥耙組成。進入濃縮池的礦漿其固體礦粒在自身重力的作用下沉降于池底，實現固液分離，沉積于底池的礦泥被刮泥耙連續不斷地刮集到中心排礦口排出，而澄清水由池邊溢流口溢出，達到脫水濃縮的目的。

        Laboratory thickening equipment model NSL-66  which is designed for dehydration of  products (ore slurry) after wet type ore separation is composed of thickening  tank and mechanical scraper rake. The solid ore grains in the slurry inside  thickening tank sedimentate on the tank bottom under gravity. In this way,  solid-liquid separation is realized. The sludge deposit on tank bottom will be  continuously scraped by scraper rake to central discharge port at which it is  discharged. And then, clear water will flow out from overflow port at the tank.  At this point, dehydration and thickening is realized.

三、傳動過程及結構

III. Transmission Process and Structure

        NSL-66型試驗室濃縮機由濃縮池、耙架、減速裝置、提耙裝置、進料槽等組成。

Laboratory thickening equipment model NSL-66 is composed  of thickening tank, rake holder, reduction gear, rake lifting device and feed  chute etc.

傳動時由減速電機帶動主軸和耙架逆時針方向低速轉動，沉降礦粒被連續刮集到排礦石漏斗排出。

As to transmission, the reducer motor drives spindle and  rake holder to rotate counterclockwise at a low speed. During this process, ore  grains are continuously scraped to discharge hopper and discharged.

轉動提耙手輪，可以提升或下降耙架，當濃縮池內沉降的礦粒過厚埋住耙架而超載時，應轉動提耙手輪，將耙架從礦粒層中提起，載荷減輕后，又將耙架下降到工作位置。

Rotate the hand wheel for rake lifting to lift  or lower the rake holder. In case the excessively thick layer of ore grains  inside thickening tank cover the holder and thus lead to over-load, the hand  wheel shall be rotated so as to lift the holder from the layer of ore grains.  The holder shall be then lowered to operating position after the load is  reduced.
