Belt Pulp Sludge Filter Press Application:
The pulp sludge filter press is a mechanical equipment developed and designed for the recycling of pulp separated by the paper-plastic separator. It is suitable for the separation and recycling of coated paper, kraft belts, milk cartons, sanitary napkins, diapers, packaging paper labels, secondary materials from paper mills, etc. It can reduce pollution emissions and increase economic utility. After continuous updating and improvement, the whole machine has the characteristics of compact and reasonable design, saving space, stable operation, low failure rate, automatic deviation correction, simple use and operation, efficient production and convenient maintenance.
Belt Pulp Sludge Filter Press Description:
The belt pulp filter press is a water treatment equipment successfully developed after introducing advanced technology from abroad. It can continuously press and filter a large amount of sludge. The product is made of high-strength materials and has large processing capacity and high dehydration efficiency. It has distinctive features such as long service life and is widely used in environmental management in various industries. The supporting equipment it is equipped with has long service life and uses high-quality filter belts to ensure the performance and quality of the filter press.
The tension of the filter belt is realized by the inflated cylinder, so that the entire filter belt maintains constant tension; at the same time, the tension will not change due to changes in the feed amount, making operation and management convenient. The filter press has an air pressure control system that automatically detects the position of the filter belt on the pressure roller and automatically corrects the deviation. The wide filter belt filter press is also equipped with an automatic sludge feeding device to ensure that sludge enters the filter belt evenly, thereby improving filtration efficiency and extending the life of the filter belt.
Belt Pulp Sludge Filter Press Advantage:
Automatic control, continuous;
Low energy consumption and long service life;
High dehydration efficiency and high solid content of mud cake;
Easy to manage and maintain;
Low noise and less chemicals;
Economical, reliable and wide in application range.
Belt Pulp Sludge Filter Press Working Principle:
Gravity dehydration area
The sludge from the wastewater treatment plant is pumped into the sludge mixing tank and mixed with the polymer flocculant (Polymer), so that the fine suspended particles in the sludge are formed into latex (Elo) by the bridging effect of the polymer flocculant. The larger particles in the shape are then overflowed from the upper end of the mixing tank into the automatic distribution device of the dewatering machine in a gravity flow manner, so that the latex sludge is evenly distributed on the filter cloth in the gravity dewatering area. The function of the gravity concentration and dehydration zone is to discharge most of the free water outside the latex sludge through the mesh of the filter cloth by gravity to increase the sludge concentration and stabilize the properties of the latex sludge, which is beneficial to subsequent pressing and dewatering operations.
Pressure dehydration area
After the sludge enters the pressure dehydration zone from the gravity dewatering zone, the upper and lower filter cloths begin to gradually pressurize and squeeze the sludge to dehydrate.
Pressurized dehydration area
The sludge moves with the filter cloth into the pressurized dehydration zone. Between the six vertical rollers, the diameter of the rollers is gradually reduced from large to small, and the pressure is gradually increased from small to small. The shearing force on the sludge caused by changing the upper and lower positions of the filter cloth squeezes out the capillary combined water in the latex sludge to produce a drier sludge cake.
