压滤机如何优化材料

  压力过滤过程分为过滤和压力过滤的洁净煤技术多集中在隔膜压榨隔膜压滤机的研究,通过脱水装置如吹面包和卸料速度、出料速度似乎比下游的能力甚至更大;但影响隔膜压滤机的过滤效率和能力在过滤阶段的决定性环节,尤其是难过滤材料,如粘土浆,含量高的污泥,经常把超过60%的总周期,因此,提高压滤机的生产率的关键在于如何优化材料。

 
 
  在选煤厂中,压滤机是煤泥水处理设备的最后一道,必须保证所有煤泥回收,用于处理浮选机和煤泥隔膜挤压压滤机有隔膜、强压力通过等。
 
  压滤机由于滤饼含水率低,可实现自动间歇操作,隔膜压滤机已在矿业、轻工、化工等领域得到了广泛的应用。单泵入料最压滤器采用单泵入料,即按压滤机进入所需物料泵,流量和扬程选用大流量高扬程泵,优点是结构简单,施工方便,投资少。
 
  同时,单泵的材料也有缺点,在填充开始会产生极大的耐介质性能,为材料,电阻越大,而相应的泵灌装压力较大,从而导致滤布表面形成滤饼层破坏,浆液中增加,过滤器的过滤水的浊度。
 
  The pressure filtration process is divided into filtration and pressure filtration. The clean coal technology is mostly concentrated on the diaphragm press diaphragm filter press. The dewatering device such as the breading and unloading speed, the discharge speed seems to be even larger than the downstream capacity; The filtration efficiency and capacity of the membrane filter press are at the decisive point in the filtration stage, especially for difficult-to-filter materials such as clay slurries, high-content sludge, which often exceeds 60% of the total cycle, thus increasing the productivity of the filter press. The key is how to optimize the material.
 
  In the coal preparation plant, the filter press is the last of the slime water treatment equipment, and all the slime recovery must be ensured. The flotation machine and the slime membrane squeeze filter press have a diaphragm and strong pressure.
 
  Due to the low moisture content of the filter cake, the filter press can realize automatic intermittent operation. The diaphragm filter press has been widely used in the fields of mining, light industry and chemical industry. The single-pump feed most pressure filter adopts single-pump feeding, that is, presses the filter to enter the required material pump, and the flow rate and lift adopts high-flow high-lift pump. The advantage is simple structure, convenient construction and low investment.
 
  At the same time, the material of the single pump also has disadvantages。 At the beginning of filling, it will produce great resistance to medium。 As the material, the electric resistance is larger, and the corresponding pump filling pressure is larger, resulting in the formation of filter cake layer on the surface of the filter cloth。 Increase the turbidity of the filtered water of the filter。
