Belt Filter Printing Dyeing Sludge Water Treatment Belt Filter Press Machine
Product Description:
Belt filter press The dehydration process of belt filter press can be divided into four important stages: pretreatment, gravity dehydration, wedge zone pre-pressure dehydration and pressure dehydration. The technology uses new equipment filter presses, such as program-controlled automatic chamber filter presses, diaphragm filter presses, deep sludge dehydration filter presses, integrated sewage sludge treatment equipment, and online precision filtration systems. Reasonably priced, reliable and environmentally friendly filtration products.
The independent concentration section can easily filter the coagulated sludge, greatly improving the processing capacity. Simple structure, simple operation and easy maintenance. Special concave and convex roller design, large processing capacity and low water content. Superior patented filter belt, fast filtrate separation, excellent mud cake peeling, less sludge residue. Good sludge capture rate and high efficiency. High stability and excellent durability. No noise and vibration. Low power consumption. The filter cloth is non-sticky to sludge, and the equipment requires less cleaning water.

Working principle and workflow:
After the concentrated sludge is fully mixed with a certain concentration of flocculant in a static and dynamic mixer, the tiny solid particles in the sludge are aggregated into larger floccules, and free water is separated at the same time. The flocculated sludge is transported to the filter belt for concentrated gravity dehydration. Under the action of gravity, the free water is separated to form stagnant sludge, which is then clamped between the upper and lower mesh belts. Under the action of the squeezing force and shear force from small to large in the wedge-shaped pre-pressing area, low pressure area and high pressure area, the sludge is gradually squeezed to achieve the maximum separation of mud and water, and finally forms a filter cake for discharge.
1. Chemical pretreatment dehydration
In order to improve the dehydration of sludge, improve the properties of filter cakes, and increase the permeability of materials, the sludge needs to be chemically treated. The belt filter press uses the "water flocculation granulation mixer" device to achieve the effect of chemical dosing flocculation. This method not only has a good flocculation effect, but also saves a lot of reagents and has low operating costs.
2. Gravity concentration and dehydration section
The sludge is evenly fed into the mesh belt through the cloth hopper. The sludge moves forward with the filter belt. The free water flows into the water receiving tank through the filter belt under the action of its own weight. Gravity dehydration can also be said to be a highly concentrated section. Its main function is to remove free water from the sludge, reduce the fluidity of the sludge, and prepare for further extrusion.
3. Wedge-shaped zone pre-pressure dehydration section
The fluidity of the sludge after gravity dehydration is almost completely lost. As the filter belt of the belt filter press moves forward, the distance between the upper and lower filter belts gradually decreases, and the material begins to be slightly pressed. As the filter belt runs, the pressure gradually increases. The role of the wedge-shaped area is to extend the gravity dehydration time, increase the extrusion stability of the flocs, and prepare for entering the pressure zone.
4. Squeeze roller high-pressure dehydration section
When the material leaves the wedge-shaped area, it enters the pressure area. The material is squeezed in this area. The pressure along the running direction of the filter belt increases with the decrease of the squeezing roller diameter. The material shrinks in volume due to squeezing, and the interstitial free water in the material is squeezed out. At this time, the filter cake is basically formed. Continue forward to the high-pressure area at the tail of the pressure, and the water content of the filter cake can be reduced to the minimum after high pressure.
Features:
The belt filter press has a compact structure, novel style, convenient operation and management, large processing capacity, low filter cake moisture content and good effect.
1. The first gravity dewatering section is inclined, which increases the height of the sludge in the gravity dewatering section and improves the gravity dewatering capacity.
2. The gravity dewatering section is long, with a total length of more than 5m for the first and second gravity dewatering sections, so that the sludge is fully dehydrated and loses fluidity before pressing. At the same time, the gravity dewatering section is also equipped with special mechanisms such as reversal, and the sludge filter cake obtains the lowest moisture content through "wedge" and "S" shaped pressing.
3. The first dewatering roller adopts a "T" type drain trough to quickly discharge a large amount of water after pressing, thereby improving the dewatering effect.
4. The filter belt deviation is equipped with an automatic control device, and the filter belt tension and filter belt moving speed can be freely adjusted, which is convenient for operation and management.
5. Low noise and no vibration.
6. Small amount of chemical drugs
Applications:
Belt filter press is suitable for sludge dehydration in wastewater treatment processes in urban sewage treatment plants, pharmaceuticals, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemicals, slaughtering, food, brewing, coal washing and environmental protection projects. It can also be used for solid-liquid separation in industrial production. It is an ideal equipment for environmental governance and resource recovery.
