Sand field mud dewatering integrated machine

The integrated sand field mud dewatering machine, also known as belt sludge dewatering machine or belt concentration press machine, is mainly used for filtering and dewatering residual sludge or mixed sludge from sewage biochemical and physicochemical treatment, reducing its volume for further processing.

Working principle of sand field mud dewatering integrated machine
The pressing and dewatering process of belt filter press can be divided into four stages: chemical pretreatment dewatering, gravity concentration dewatering, wedge-shaped zone pre pressing dewatering, and squeezing roller pressing dewatering.
1. Chemical pretreatment dehydration:
After the mixing reaction between the flocculant mixer and the sludge, the tiny solid particles in the sludge aggregate into larger flocs. When the flocs are sent to the filter press conveyor belt, the water in the flocs falls through the filter screen under the action of gravity, infiltrates and separates, forming a free water flow into the lower receiving tank.
2. Gravity concentration dehydration
During the transportation process, the moisture in the sludge flocs gradually decreases, forming a solid with poor fluidity. The dewatering efficiency of the gravity dewatering section mainly depends on the properties of the filter belt, sludge properties, and the degree of sludge flocculation. The gravity dehydration process will remove a significant amount of water.
3. Wedge preloading dehydration stage:
After gravity concentration and dewatering, the fluidity of the sludge significantly deteriorates. As the filter belt moves forward, the distance between the filter belts gradually decreases and the pressure gradually increases. The sludge undergoes slight squeezing and dewatering in this section to remove free water on its surface and increase the stability of flocs, ensuring that the sludge is not squeezed out in the squeezing and dewatering section under normal conditions, creating conditions for smooth squeezing and dewatering.
4. Squeezing roller press dewatering:
The material enters the pressure zone, and as the pressure decreases with the diameter of the squeezing roller in the direction of the filter belt, the sludge undergoes volume contraction due to squeezing. The water in the gaps inside the sludge material is squeezed out, forming a filter cake. Under the squeezing pressure from small to large in the wedge-shaped preloading zone, low-pressure zone, and high-pressure zone, the sludge is gradually squeezed to achieve a degree of separation between sludge and water, and finally a filter cake is formed and discharged.
