Due to the rapid development of China's modern industrial filter cloths, filter bags, filter belts and other filter media industries, the mineral resources have dried up day by day. The mined ore has been facing the situation of "poverty, fineness and miscellaneous." Therefore, people have to put ore Mill more fine, while the "fine. Mud. Sticky" material to stop the filter press, frame filter, vacuum belt filter, disc filter, centrifuge, bag filter solid-liquid separation. In addition to a high degree of request for energy saving and environmental protection, the company put forward higher and wider requirements for solid and liquid technologies and equipment, and also put forward higher and wider requirements for the social demand of beneficiation, metallurgy, petroleum, coal, chemical, food, environmental protection and other industries. The solid-liquid separation from the application of technology and equipment, and its scope of application breadth and depth are still expanding from time to time.
The reason why the filter cloth can flourish and be widely used by various industries.The biggest advantage is the positive pressure, high pressure and pressure dehydration, the pressure difference is much greater than the traditional vacuum filter, so the filter cake has low moisture. Less energy consumption. Less metal loss. Clear and transparent filtrate. As early as ten years ago, some experts pointed out.
Filter press filter cloth is the only filter in all industrial filter cake to ensure that the moisture reaches below 10%. And can not flocculant excellent equipment.
Filter press filter cloth on the way in terms of the plate, there is box and box-type points, on the filter plate placed in different positions. There are vertical and horizontal points, on the filter board of different materials. Plastic. Rubber. Cast iron. Cast steel. Carbon steel. Stainless steel points, the filter plate can be equipped with rubber extrusion film. Squeeze dehydration and does not squeeze dehydration of the filter plate on the configuration number of filter cloth. Double-sided dehydration and so on.
But no matter what kind of filter press. The working principle of the first is the positive pressure squeeze dehydration. Also known as pulp dehydration. A certain number of filter plates in a strong mechanical force is arranged in a row. The filter material is sent to the filter chamber under a strong positive pressure, the filter material entering the filter chamber is partially filtered by the filter medium (such as filter cloth) to form a filter cake, and the liquid is partially discharged through the filter medium Filter chamber. So as to achieve the purpose of solid-liquid separation. With the increase of positive pressure. Solid-liquid leave more completely.
But from the energy and cost considerations.Overway pressure is not cost-effective.After the pulp dewatering.Equipped with a rubber squeeze film filter.When the compression medium (such as gas.Water) into the squeeze film on the reverse push Press the cake to squeeze the cake further dehydration.It is squeezed dehydration.Water into the pulp dehydration or squeezing dehydration after the compressed air into the filter cake side of the filter cake through the liquid carrying moisture from the other side of the filter cake through If the filter cloth is drained on both sides of the filter cloth, the liquid can be partially filtered through the filter cloth on both sides of the filter chamber to filter the double-sided dewatering of the filter chamber. After lifting the filter plate mechanical compression force gradually opened the filter plate. Open the filter chamber to stop the unloading cake was completed as a major work cycle. Depending on the nature of the filter material. Filter press can be set into the pulp dehydration. Pressure dehydration. Wind and dehydration or single. Double-sided dehydration. The purpose is to minimize the water filter cake.
