Stacked screw sludge thickener-stacked screw sludge dewatering machine
The working process of the sludge dehydrator: the sludge in the sludge tank is transported to the metering tank through the sludge delivery pump, the amount of sludge is adjusted by adjusting the liquid level adjustment pipe in the metering tank, and the excess sludge is returned to the sludge tank through the return pipe.

Description
Water resources are indispensable natural resources for human production and life, and also environmental resources for biological survival. With the aggravation of water resources crisis and the continuous deterioration of water environment quality, water shortage has become one of the resource and environmental problems that have attracted much attention in the world. Stacked screw sludge dewatering machine can be widely used in municipal sewage treatment projects and petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industrial water treatment systems.
stacked screw sludge dewatering machine work flow:
1. The sludge in the sludge tank is transported to the metering tank through the sludge delivery pump, and the amount of sludge is adjusted by adjusting the liquid level adjustment pipe in the metering tank, and the excess sludge is returned to the sludge tank through the return pipe.
2. Sludge and flocculant are fully mixed with a mixer in a flocculation mixing tank to form alum flowers. The ideal alum flowers have a diameter of about 5mm. 3. Alum is concentrated by gravity in the concentration part, and a large amount of filtrate is discharged from the filter seam of the concentration part.
4. The concentrated sludge continues to move forward along the direction of rotation of the screw shaft, and is fully dehydrated under the internal pressure formed by the back pressure plate.
5. The dehydrated mud cake is discharged from the gap formed by the back pressing plate and the spiral body. The amount of sludge treated and the moisture content of the mud cake can be adjusted by adjusting the rotation speed of the screw shaft and the gap of the back pressure plate. The flocculation mixing tank blowdown pipe is only used when cleaning the mixing tank.
Stacked screw sludge dewatering machine features:
1. Sludge dewatering machine has short working cycle and high efficiency: high pressure extrusion can greatly reduce the water content in the cake in a short period of time. 2. Sludge dewatering machine has low operating cost: fully automatic control program. This diaphragm filter press can be unattended, saving operating costs.
3. The operation of the sludge dewatering machine is simple: the cleaning device is adopted, and there are several actions to synchronize with the car plate moving machine. Can be set according to the needs of the washing cycle (field adjustable) 4, sludge dewatering machine low power consumption: diaphragm pressing function, in a very short time to complete the process, saving power consumption.
5. Wide application of the stacked screw sludge dewatering machine: strong corrosion resistance, basically suitable for all solid-liquid separation projects
RKC stacked screw sludge thickener is a new type of sludge thickening device with the same principle as the stacked screw sludge dehydrator. The device relies on a unique filter structure and has the advantages of continuous unattended 24-hour operation, low energy consumption, high thickening efficiency, non-blocking and high thickening efficiency.
