What is paper plastic composite woven bag?
Paper plastic composite woven bag is a packaging bag made of plastic woven cloth and paper. It has the characteristics of waterproof, wear-resistant and high strength, and is widely used for packaging chemical raw materials, building materials, feed, food and other powdery or granular materials..
Why recycle Paper-plastic composite woven bag?
Paper-plastic composite woven bags are composite materials. The plastic part is not easy to degrade. If it is directly burned, it will produce toxic gases. If it is directly landfilled, it will occupy a lot of land resources. Therefore, recycling paper-plastic composite woven bags can reduce the generation of solid waste and protect the environment.
Both paper and plastic parts in paper-plastic composite woven bags can be recycled. Recycled paper can be used to produce new paper products, and recycled plastic can be used to produce new plastic products, which can save resources and reduce the consumption of virgin wood and oil.
Why do we need to separate paper from plastic?
Paper and plastic recycling separators can separate the pulp and plastic in the material to form a single material structure. The separated plastic is processed into plastic particles through the plastic washing machine and the two-stage plastic pelletizer/granulator, which facilitates transportation and achieves better utilization value; Paper pulp can be pressed into pulp boards, which greatly improves economic benefits, achieves the rational use of renewable resources, reduces the burden of solid waste disposal, and continuously provides kinetic energy for creating a green ecological environment!

This machine has the characteristics of closed operation, no splashing, high fiber retention rate, low processing cost and quick investment recovery.
In waste paper pulping, due to the different paper quality, there is a lot of residue. This machine can remove light and heavy debris and decompose small pieces of paper in the fiber. It will not block the screen plate, and hard debris will not damage it. Screen plate, the factory does not need to stop operation frequently for cleaning, and it can also be used as a second bulk machine. It is mainly used for sorting tail pulp after fiber separator and pressure screen; the processed and sorted pulp is directly returned to the pulp tank in front of fiber separator or pressure screen for reuse. The tailings discharged after sorting do not contain fiber and comply with environmental emission requirements. It has been used with remarkable results in many paper mills.

Pulp Dewatering Machine
Pulp dewatering machine is an improved design imported from foreign prototypes. It uses the principle of rotating micropore filtration to carry out closed and complete filtration treatment of wastewater (ink or white water) generated in the pulping and paper making process. It not only regenerates the lost fibers in the paper making wastewater. Recycling and filtered wastewater can be used twice, making full use of and saving water resources.
Pulp dewatering machine is used for pre-dehydration in paper making and pulping or paper-plastic separation and pulp recycling. After pre-dehydration, the pulp enters the pulping dewatering machine and then is pressed and dehydrated.
Purpose:
Used for fiber recovery in papermaking wastewater
This machine is widely used for the treatment of black and white wastewater generated during concentration, washing, screening, bleaching, copying and other processes in the pulping process.
In the pulping and paper-making process, the loss of fiber is inevitable. Theoretically, the total loss accounts for about 1.5-3% of the total fiber. In fact, the fiber is much higher than this proportion; its recycling value is very considerable; according to the recovery rate of 90 %, calculated based on the daily production capacity of 30 tons of paper, 810Kg of absolutely dry pulp can be recycled every day, and the price is more than 1,000 yuan. The economic benefits are quite obvious.

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.
The belt 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.

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.
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.
