GPZ ceramic disc-type filter is a kind of  new filtering equipment developed according to features such as high density of  metallic minerals, fast settling velocity, large viscosity, and strong  corrosiveness. Such equipment has characteristics such as firmness and  durability, steady operation of filter disc, automatic to intense agitation,  reliable sealing at shaft end, and slurry leakage resistance. Compared with  drum vacuum filters, such filter enjoys the following advantages:

1. The moisture of filter cake reduces by  1% to 2%.  2. Filtration coefficient  increases by 30% to 50%. 3. The land occupying area reduces by 50% and energy  consumption reduces by 30%. 4. It employs advanced technology such as  centralized lubrication of automatic area and display of imitation screen.

GPZ ceramic disc-type filters are  optimally designed according to features including high density of metallic  minerals, fast settling velocity, large viscosity and strong corrosiveness. It  has characteristics such as firmness and durability, steady operation of filter  disc, high rate of cake discharging, automatic centralized lubrication, display  of imitation screen, automatic control operation, and adoption of high-strength  engineering plastics filter fan. Their automatic to strong variable speed  agitation and reliable shaft end sealing technology was granted utility new  patented technology for 1999. All these technology is reliable guarantee to  ensure metallic minerals acquire fine dewatering indicators. Compared with  commonly used drum vacuum filters, they enjoy these advantages: The moisture of  filter cake reduces by 1% to 2%; filtration coefficient increases by 30% to  50%; the land occupying area reduces by 50% and energy consumption reduces by  30%.

主要用途

Main Application

该机是为了铁精矿、有色金属精矿脱水工作而特别设计的新型盘式真空过滤机，也适合在洗煤选矿、非金属矿、化工、环保作业中使用。

This machine is a new kind of disc-type  vacuum filter specially designed for the dewatering of concentrate of steel and  nonferrous metal. It can also be used in operation such as coal washing and ore  dressing, nonmetallic ore, chemical, and environmental protection.

其主要技术特点如下

Its main technical characteristics are:

1、结合现有滤扇使用的一些缺陷，我们设计的新型滤扇，脱水孔分布均匀，孔率合理，强度大（滤扇材料为高强度工程塑料），使用寿命长，寿命平均提高1—1.5倍，而且滤布的使用寿命长。同时滤扇的有效面积较大，提高了过滤机的处理能力。

1. Overcoming some defects in the use of  existing filter fans, the new filter fans we designed are characterized by even  distribution of dewatering holes, reasonable aperture ratio, high strength (the  material of screen fans is high strength engineering plastic), long service  life (the life increases 1 to 1.5 times on average) of it, as well as long  service of filter cloth. Besides, the effective area of screen fans is large  which improves the handing ability of filter.

2、对滤液管的结构进行了优化设计，彻底排除了原法兰连接处由于胶皮老化产生的漏气现象。

2. The structure of filtrate pipe is  optimally designed. Leakage due to aging of rubble at the joint of original  flange is completely avoided.

3、搅拌轴轴端采用国内首创“橡胶、永磁铁、水封”三重组合柔性密封方式，有效的防止了矿浆渗漏。

3. The ends of agitating shafts adopt the  flexible sealing method of three elements “rubber, permanent magnet, and water  seal” initiated in China which effectively prevent leakage of slurry.

4、采用特制耐磨硼铸铁摩擦片，刚柔相济密封效果好。

4. Specially made abrasion-resistant boron  cast-iron friction plates are adopted which produce good sealing effects.

5、滤液管为高强度耐磨陶瓷复合钢管，寿命延长5倍以上。

5. The filtrate pipes are high-strength  and abrasion-resistant ceramic lined steel pipes whose service life is  prolonged for over 5 times.

6、采用10个弧形小压块连续互扣将滤扇压住定位在一个平面内。使检修人员更换滤扇或滤布时工作量减少，劳动强度大幅降低。

6. Ten arc small press cakes are adopted  for successive mutual gripping to press the screen fans within a plane. This  helps the maintenance persons to have less work during the replacement of  filter fans or filter cloth. Their labor intensity is reduced substantially.

7、传动无级变速，依物料的浓度及流量调节（交流调速电机或变频器）以求达到理想的工作效果。

7. Continuously variable transmission is  adjusted according to the concentration and flow of materials (adjustable speed  motors with alternating current or frequency converter) to achieve ideal  working effects.

8、干油泵集中多点自动润滑，保证设备正常运行。

8. The dry oil pump is lubricated  automatically at many points to ensure normal operation of equipment.
