NJG型高效濃縮機 High-effiency thickener series

本濃縮機是引進德國技術研制的一種新型高效濃縮機，該機集傳統中心傳動濃縮機、周邊傳動濃縮機的優點于一體，為國內首創，是傳統濃縮面的更新換代產品，廣泛應用于處理稠重的工業料漿，如煤炭，金屬選礦水，冶金廢水，化工料漿等。

Such thickener is a kind of new high-efficiency thickener  developed relying on German technology. This machine has both the advantages of  traditional central driving thickeners and peripheral traction thickeners. It  is originated in China and is regeneration product of traditional thickener. This type of thickeners  is widely used to treat thick industrial slurry such as coal, metal ore  dressing water, metallurgical wastewater, and chemical slurry.

1、中心深層入料，平流沉降，減少了沉降高度，降低固相顆粒的動能，并且，耙架為連桿式結構，減少對顆粒沉降的干涉，加速了濃縮壓積過程，處理能力可提高30~50%，如添加絮凝劑，處理能力還能大幅提高。2、池底三種角度，方便沉降物料的刮集，土建立經濟性好。3、設有中心攪拌裝置，底流濃度提高，集料錐坑中物料不會固結4、液壓自動分段提耙，提耙動作可靠5、提耙高度可根據需要勝地意調整，最高可把刮板提至水面以上，方便檢修。6、長時間停機及遇到故障可自動，手動操作機器清池，不需放水，不影響生產7、驅動橋架旋轉的周邊驅動裝置，可無級調速，滿足不同生產工況要求8、整機用用PLC程序控制，實現超載報警指示，自動控制提耙，降耙（采用壓力傳感受器或轉矩傳感器，檢測工作阻力），可自動，手動或遠程集控。9、集電裝置為全密封結構，集電可靠，安全。10、主要配套件采用進口，合資或國產名牌，質量可靠。

1. Materials are fed into the deep layer of the center. The  horizontal flow settles which reduces the settling height and reduces the  kinetic energy of solid particles. Besides, the rake is of connecting rod  structure, which reduces the interference with the settlement of particles and  expedites the concentration and accumulation process. With it, the handling  ability can increase by 30% to 50%. If flocculant is added, the handling  ability will greatly improve. 2. The three angles at the sink bottom make it  easy for the scraping of settling materials. Earth building is economical. 3.  It is equipped with center stirring device. The concentration of underflow is  increased and the materials in the aggregate counter sink will not be  solidified. 4. The hydraulic automatic section rake works reliably. 5. The  height of lifting can be adjusted at random according to actual needs. The  scrapper can be lifted to above the water surface at most so as to make it easy  for examination and repair. 6. In case of long-time shutdown or failures, the  machine can be operated manually. Water does not have to be discharged during  cleaning of sink with production not affected. 7. Stepless speed regulation can  be made of the peripheral drive unit which drives the rotation of bridge, to  meet the requirements of different working conditions. 8. The complete machine  is controlled by PLC program to realize overload alarm, automatic control of  lifting rake and lowering rake (pressure sensor or torque sensor is adopted to  detect working resistance), as well as automatic, manual or remote centralized  control. 9. The current collecting equipment is of all-sealed structure whose  current collection is reliable and safe. 10. The main accessories are foreign  or domestic well-known products whose quality is reliable.
