NXZ型液壓提升高效濃縮機 High-effciency  thickener with hydro-lifting

NXZ型濃縮機是引進美國技術研制的一種新型中心傳動、自動提耙高效濃縮機。廣泛適用于處理各種工業料漿，如煤炭、金屬選礦水、化工料漿等。

NXZ thinkener is a kind of new high-efficiency thinkener with  center drive and automatic rake lifting developed through American technology.  They are widely used to treat all kinds of industrial slurry such as coal,  metal ore dressing water and chemical slurry.

主要特點：1、處理量大，濃縮效率高，處理量可達2.5-4m³/㎡h，采用深層入料、平流沉降技術，減少了沉降高度、降低固相顆粒動能。配有加藥裝置，進料管中設置靜態混合器及三個加藥點，使藥劑與物料充分混合，絮凝沉降效果。

Main Characteristics: 1. Its handling capacity is large (as high  as 2.5-4m³/㎡h) and concentration efficiency is high. It  adopts deep feeding and horizontal flow settlement technology which reduce the  settling height and kinetic energy of solid particles. It is equipped with  drug-feeding equipment. Static mixers and three drug-feeding points are set in  the feeding pipe to enable intensive mixing of reagent and materials and  flocculation settling results.

2、液壓雙驅動，無級調速，機械強度高，并具有過載保護功能，中心傳動裝置結構為兩個液壓馬達減速機同步驅動中心回轉支承外齒圈，從而帶動主軸及耙架旋轉，并可無級調速，滿足不同工況要求。主軸為大直徑厚壁管軸，機械強度高，穩定性好。傳動箱蓋位于油面之上，永不漏油，傳動裝置潤滑良好。設有壓力控制裝置，過載自動停機，不會毀壞設備。

2. It features hydraulic double driving, stepless speed  regulation, and high mechanical strength. Besides, it is equipped with overload  protection function. The structure of center transmission devices is two  hydraulic motor speed reducers which simultaneously drive external gear rings  of slewing bearing so as to drive the rotation of main shaft and rake. Besides,  speed can be regulated steplessly to meet requirements of different working conditions.  The main shaft is one with

 large diameter and thick wall which enjoys high  mechanical strength and good stability. The transmission case cover is above  the oil level. Oil can never be leaked. The lubrication of transmission device  is good. It is also equipped with pressure control device and will shut down  automatically in case of overload. Hence the equipment will not be damaged.

3、液壓自動提耙裝置和液壓驅動裝置共用一個組合式液壓泵站，以油壓反應刮泥阻力，主軸及耙架會隨刮泥阻力變化自動升降，不會壓耙。

3. The hydraulic automatic rake lifting device and hydraulic  transmission device share one combined type hydraulic power unit which indicate  sludge scraping resistance with oil pressure. The main shaft and rake will go  up and down automatically with the change of sludge scraping resistance. They  will not press the rake.

4、設置消泡機構，溢流水濃度降低池面泡沫，細物料充分沉淀，很少進入溢流，溢流水變清。

4. Defoaming mechanism is installed. The concentration of overflow  water reduces and no foam appears on the surface of the tank. Fine materials  fully precipitate; overflow water get in very seldom. The overflow water  becomes clean.

5、傳動裝置結構簡單、維修方便。

5. The transmission device is simple in structure and easy for  maintenance.
