陆海选煤厂压滤系统的改造

Filter system transformation of Luhai coal preparation plant

陆海选煤厂自投产以来,其压滤系统就存在现场卫生量大、噪音高、设备运行缺乏连动性及能源浪费等问题,我们针对现场实际情况确定了系统改造方案,其中快开压滤机反吹风系统改造从根本上降低了现场卫生污染和噪音污染问题;压滤机与运输刮板机的联锁改造杜绝了由于过多堆积物料而引起的设备堵压故障;碎饼装置改造降低了职工的劳动强度、解决了大块滤饼进入下料溜槽发生蓬仓事故的机率,消除人工疏通煤仓时存在的安全隐患;精煤刮板水煤分离的改造降低了精煤产品的水分含量,减轻了岗位司机的劳动强度;滤液水回收利用的改造充分利用了压滤机的滤液水,节约了水能源。这一系统的改造提高了人、机安全,使现场工作达到标准化要求。

Since the production of LuHai coal preparation plant,Its pressure filtration system exsits site health capacity, high noise, the lack of mobility equipment operation, waste of energy and other issues. We focus on the actual situation to determine the system transformation plan,which fast opening filter anti-hair system transformation reduces site health pollution and noise pollution problem fundamentally. Interlocking Reconstruction Filter and transport scraper machine eliminates equipment failure due to excessive blocking pressure caused by the accumulation of material. Broken bread device reduces the labor intensity of workers, solves the big cake into the feeding chute which occurr warehouse accident probability, eliminates the security risks of artificial dredge coal. Coal coal-water separation scraper transformation reduces the moisture content of the coal transformation products,reducing the labor intensity of the driver job. The filtrate water recycling transformation make full use of the filtrate water filter press, saves water energy. Transformation of the system improves the human,machine safety,in order to achieve the standardized requirements of field work.
