板框压滤机有操作要领吗?

 第一步压紧:压滤机操作前须进行整机检查:查看滤布有无打折或重叠现象,电源是否已正常连接。检查后即可 进行压紧操作,首先按一下“启动”按钮,油泵开始工作,然后再按一下“压紧”按钮,活塞推动压紧板压紧,当压紧力到达调定高点压力后,液压系统自动跳停。

 
First step press: press filter before operation must be checked: check whether there is discount or overlap filter cloth, power supply is normal connection. After checking, the press operation can be carried out. Firstly, press the "start" button, the oil pump starts to work, and then press the "press" button, the piston pushes the pressure plate to press, when the pressure reaches the set point pressure, the hydraulic system automatically stops.
 
第二步进料:当压滤机压紧后,即可进行进料操作:开启进料泵,并缓慢开启进料阀门,进料压力逐渐升高至正常压力。这时观察压滤机出液情况和滤板间的渗漏情况,过滤一段时间后压滤机出液孔出液量逐渐减少,这时说明滤室内滤渣正在逐渐充满,当出液口不出液或只有很少量液体时,证明滤室内滤渣已经完全充满形成滤饼。如需要对滤饼进洗涤或风干操作,即可随后进行,如不需要洗涤或风干操作即可进行卸饼操作。
 
Second step feeding: When the filter press is compressed, the feeding operation can be carried out: open the feeding pump, and slowly open the feeding valve, feeding pressure gradually increased to normal pressure. After a period of filtration, the amount of liquid discharged from the outlet hole of the filter reduces gradually, which indicates that the filter residue in the filter chamber is gradually filled. When the outlet of the filter is not liquid or only a small amount of liquid, it proves that the filter residue in the filter chamber has been fully filled to form a cake. If the filter cake needs to be washed or air-dried, it can be carried out subsequently, and unloading operation can be carried out without washing or air-drying operation.
 
第三步洗涤或风干:压滤机滤饼充满后,关停进料泵和进料阀门。开起洗涤泵或空压机,缓慢开启进洗液或进风阀门,对滤饼进行洗涤或风干。操作完成后,关闭洗液泵或空压机及其阀门,即可进行卸饼操作。
 
The third step is washing or air drying: after the filter cake is filled, the feed pump and the feed valve are shut down. Open the washing pump or air compressor, slowly open the intake liquid or air valve, wash or air-dry the filter cake. After the operation is completed, the lotion pump or air compressor and its valves are closed, and the unloading operation can be carried out.
 
第四步卸饼:首先关闭进料泵和进料阀门、进洗液或进风装置和阀门,然后按住操作面板上的“松开”按钮,活塞杆带动压紧板退回,退至合适位置后,放开按住的“松开”按钮,人工逐块拉动滤板卸下滤饼,同时清理粘在密封面处的滤渣,防止滤渣夹在密封面上影响密封性能,产生渗漏现象,至此一个操作周期完毕。
 
Fourth step unloading cake: first close the feed pump and feed valve, wash or air inlet device and valve, and then press the "release" button on the operation panel, the piston rod drive the pressure plate back, back to the appropriate position, release the pressed "release" button, manually pull the filter plate to unload the cake, while cleaning the sticky at the same time The filter residue at the cover prevents the filter residue from clipping on the sealing surface and affecting the sealing performance, resulting in leakage, and the operation cycle is completed.
