Dehydrating Sludge Belt Filter Press 3 - 5.2m3/H Capacity 0.75kw Motor Power
Belt filter press introduction
Belt filter press is a new type based on international advanced technology which was introduced by national scientific research unit and our company. It can be widely used in sludge dewatering of urban sewage treatment, chemical industry,oil refining, metallurgy,papermaking, leather making, foodstuff, coal washing and printing and dyeing industry. It is an ideal equipment to sludge dewatering with advantages of continuous work, high automation, energy saving, high efficiency, and easy maintenace.
The belt press filter mainly consists of a driving device, a frame, a press roll, an upper filter belt, a lower filter belt, a filter belt tensioning device, a filter belt cleaning device, a discharging device, an air control system, and an electrical control system.
How folding works
How folding works
After the concentrated sludge and a certain concentration of flocculant are fully mixed in a static and dynamic mixer, the small solid particles in the sludge are aggregated into a large flocculent mass, and free water is separated at the same time. The sludge is transported to the concentrated gravity dewatering filter belt, and free water is separated under the action of gravity to form sludge in a non-flowing state, and then it is clamped between the upper and lower mesh belts and passes through the wedge-shaped pre-pressure zone and low pressure. The zone and high-pressure zone are gradually squeezed under the action of small to large squeezing and shearing forces to achieve the maximum degree of mud and water separation, and finally a filter cake is discharged.
1. Chemical pretreatment dehydration
In order to improve the dewaterability of sludge, improve the properties of filter cake, and increase the permeability of materials, chemical treatment of sludge is required. This machine uses a unique "water flocculation granulation mixer" device to achieve chemical dosing and flocculation. Function, this method not only has good flocculation effect, but also saves a lot of chemicals, low operating cost and obvious economic benefits.
2. Gravity concentration dehydration section
The sludge is evenly fed into the mesh belt through the distribution bucket. The sludge runs forward with the filter belt. The free water flows into the water receiving tank through the filter belt under its own weight. Gravity dewatering can also be said to be a highly concentrated section. The free water in the medium reduces the fluidity of the sludge and prepares it for further extrusion.
3.Pre-pressure dewatering section of wedge-shaped area
The fluidity of the sludge after gravity dehydration is almost completely lost. As the belt filter press moves forward, the distance between the upper and lower filter belts gradually decreases, and the material begins to receive slight pressure. As the filter belt runs, the pressure gradually increases. The role of the wedge-shaped zone is to extend the gravity dehydration time, increase the compression stability of the floc, and prepare for entering the pressure zone.
4.High-pressure dehydration section of squeeze roller
When the material leaves the wedge zone, it enters the pressure zone. The material is squeezed in this zone. The pressure along the belt running direction increases with the decrease of the diameter of the squeeze roller. The squeezed volume of the material shrinks and the free water in the gap is squeezed out. At this time, the filter cake is basically formed, and the water content of the filter cake can be reduced to a minimum after continuing to the high pressure area at the end of the pressure.
Application
This machine is suitable for sludge dewatering in wastewater treatment processes in urban sewage treatment plants, pharmaceuticals, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemical, slaughtering, food, brewing, coal washing and environmental protection engineering. In the case of liquid separation, it is an ideal equipment for environmental management and resource recovery.
