NXZ型液压提升高效浓缩机 High-effciency  thickener with hydro-lifting

NXZ型浓缩机是引进美国技术研制的一种新型中心传动、自动提耙高效浓缩机。广泛适用于处理各种工业料浆，如煤炭、金属选矿水、化工料浆等。

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.

主要特点：1、处理量大，浓缩效率高，处理量可达2.5-4m³/㎡h，采用深层入料、平流沉降技术，减少了沉降高度、降低固相颗粒动能。配有加药装置，进料管中设置静态混合器及三个加药点，使药剂与物料充分混合，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、液压双驱动，无级调速，机械强度高，并具有过载保护功能，中心传动装置结构为两个液压马达减速机同步驱动中心回转支承外齿圈，从而带动主轴及耙架旋转，并可无级调速，满足不同工况要求。主轴为大直径厚壁管轴，机械强度高，稳定性好。传动箱盖位于油面之上，永不漏油，传动装置润滑良好。设有压力控制装置，过载自动停机，不会毁坏设备。

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、液压自动提耙装置和液压驱动装置共用一个组合式液压泵站，以油压反应刮泥阻力，主轴及耙架会随刮泥阻力变化自动升降，不会压耙。

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、设置消泡机构，溢流水浓度降低池面泡沫，细物料充分沉淀，很少进入溢流，溢流水变清。

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、传动装置结构简单、维修方便。

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