working principle DGZ fixed vacuum belt type filter press machine is the independent research and development of new filter equipment. With trait filter cloth as the filter medium, make full use of the materials of the area before the gravity and vacuum negative pressure to vacuum dehydration, vacuum dehydration area, the fixed support roller type, surrounding the small resistance of friction bar sealing structure, fast vacuum after dehydration entered the second area high pressure extrusion dehydration, two area adopts high voltage extrusion roller, squeeze the roll surface design a vacuum tank, high pressure after extrusion in high voltage vacuum dehydration areas, areas vacuum dehydration is depend on distribution dish distribution vacuum, make sure of extrusion moisture is vacuum filter. Thus continuous finish feeding, filtering, pressure filter, filter, unloaded and filter cloth regeneration process operations. http://www.heyuanjx.com.cn/
