Because of China's modern industry, the filter belt screen filter bag filter, belt filter materials, the rapid development of the industry, mineral resources increasingly exhausted. The mining ores has faced "is poor. Fine." situation. For this hybrid. People have to put more fine grinding ore. And for "fine. Mud. Stick" materials filter press, plate frame filter press, vacuum belt type filter, disc filter belt, centrifuge, bag filter. Now the solid-liquid separation. In addition to energy conservation and environmental protection high requirements. Enterprise outside of solid-liquid separation technology and equipment and put forward higher. More broadly in metallurgical mineral requirements... Oil. Coal. Chemical. Food. Environmental protection industry society needs. Pull the solid-liquid separation technology and equipment used. And the application field of the breadth and depth continues to expand.
Pressure filter is able to flourish and widely used. The industry is the greatest advantage of the positive pressure. High pressure pressure dehydration. More traditional vacuum filter machine of pressure difference. So low moisture filter cake. Less energy consumption. Metal loss less transparent. Filtrate. Back in the ten DuoNian before they have the experts said.
Filter is the at present all industrial filter machine can ensure that the only water filter cake of below 10%. And can not add flocculant of good equipment.
Filter press will filter board form in a van. And plate frame type of points, filter board placed orientation. Have vertical and horizontal different points, the filter plate quality is differ. Has the plastic. Rubber. Cast iron. Cast steel. Carbon steel. The stainless steel points, whether filter board rubber extrusion film. A configuration extrusion dehydration and not extrusion of dehydration points, filter board configuration filter belt screen cover several different. A single dehydration and double-sided dehydration, etc. Of the points
But no matter what kind of filter press. Its work principle is first is dehydration. Also called pressure pressure into a pulp dehydration. That is a certain number of filter board in strong mechanical under the action of forces to be closely in a row. Filter board face and formed between filter board face. Filter materials in the filter room strong positive pressure was sent into the room. Into the filter filter of the filter material room solid part were the filter medium (such as the filter belt screen) intercept filter cake formation. Liquid part through the filter medium and filter room. So as to achieve discharge solid-liquid separation. With the purpose of positive pressure pressure increased. Solid-liquid separation is more thoroughly.

But from energy and cost into consideration. High positive pressure pressure out. Into a pulp dehydration. Equipped with rubber extrusion after the membrane filter press. Is compressed medium (such as gas. The water) into the back of the extrusion film extrusion film extrusion push to filter cake further dehydration. Call extrusion dehydration. Into a pulp dehydration or extrusion after dehydration. Compressed air into the room one side of the filter cake of filter through filter cake. Carry liquid water filter cake from the other side of the filter belt screen filter through from room and dehydration. Call the wind dehydration. If filter room two sides apply filter belt screen. Is a liquid portion evenly through the room can filter on both sides of the filter cloth filter out room. For filter room double-sided dehydration. Dehydration. Remove after completion of the filter board mechanical compaction force. Single piece of gradually open filter board. Open the discharge respectively filter cake for a major work cycle. According to filter material properties complete different filter press respectively. Set into a pulp dehydration. Extrusion dehydration. The wind dehydration or single. Double dehydration. Purpose is to maximize reduce water filter cake.
