Feature: Vertical design.Automatic; Precision filtration, high efficiency filtration

The structure is compact, the design is reasonable, the sludge dehydration rate is high and the appearance is beautiful and generous.

The equipment covers a small area and has a long service life.

It has the characteristics of high efficiency, energy saving, high automation, tight cylinder control, automatic deviation of filter belt, continuous and reliable work and so on


Equipment principle
The working principle of the belt filter press is to enter the filter belt of the belt filter press through the hopper through the hopper, and send it into the roller through the filter belt, and squeeze the sludge water to form mud cake through the squeezing of the filter belt and the roller.


The steps of the belt filter press are divided into four stages: pre treatment, gravity dehydration, pre pressure dehydration and roll pressure dehydration.

1.Pretreatment: using gravity settlement, the original sludge is concentrated, the concentration is increased, and the volume is reduced. The sludge is mixed with polymer flocculant, coagulated into floc shape and precipitated into sludge, which is a preparation condition for dewatering in the next step of filter press.

2.Gravity concentration and dehydration section: the sludge pre treated by flocculation is sent to the filter belt of the belt filter press, and the free water outside the floc is filtered out from the filter belt to further reduce the water content of the sludge.

3.The wedge preloading dewatering section: the sludge after gravity dewatering has basically lost its fluidity after preloading and dewatering through the wedge section, which ensures the dewatering of the sludge in the dewatering and dewatering section.

4.The high pressure dewatering section of the extrusion roller: the layout of the multiple roller axes of the belt press filter is reasonable, and the sludge is repeatedly extruded and cut, so that the moisture content of the sludge gradually decreases, and then the extrusion roller is extruded, and finally, the massive mud cake with very little moisture content is finally formed, which is automatically discharged to the discharge port.


Advantage: The belt filter press has good anticorrosive performance. All fasteners are made of stainless steel, equipped with fully automatic anti bias device and pressure relief device, pneumatic control valve is connected to the cylinder, and both sides of the filter belt are rectified at the same time. According to the different needs of users, the mud intake, belt tension, belt speed and dosing amount of the belt press filter can be adjusted, so that the productivity and dehydration rate of the belt filter press can reach the best state.

Structure:
This machine consists of frame, transmission device, filter device, rectifying device, cleaning device, discharging device, and roller system, collecting tank, electrical and other components.


Work principle
The working principle of the belt type filter press: after suspension flocculation in the gravity dehydration section off most of the free water, the material has been further enriched, and then through the turnover mechanism of unloading the upper and lower filter belt, into the wedge area pre pressure dehydration, dehydration and dehydration after the Lord, enter the roller series S shaped arrangement press until the cake is formed after unloading. In the process of sludge by ascending extrusion, shear force, can remove most of the free water and capillary water.


Technological process
The whole dehydration program of the belt press filter is carried out continuously and its working process is

Flocculation mixing -- material - cloth - gravity dehydration - reverse unloading - pressure filter section prepressure dehydration -- press filter section pressing dehydration -- filter cake unloading
