Detailed introduction

Product overview

Water treatment processes generally produce aqueous sludge of different properties. Sludge dewatering equipment is mainly to reduce the water content of sludge, reduce the water content, reduce the volume of sludge, for the subsequent treatment or disposal of sludge to bring convenience. Sludge dewatering equipment can generally be divided into belt dewatering machine, centrifugal dewatering machine, plate and frame filter press and stacked screw sludge dewatering machine. At present, the belt dewatering machine is widely used in sludge dewatering in China, but it has the problems of large water consumption and high operation requirements. The stacked screw sludge dewatering machine is a new type of sludge dewatering equipment, with its energy saving, stability, high degree of automation advantages, is rapidly being recognized and accepted by the market.

Product overview

Stacked screw sludge dewatering machine is a new type of solid-liquid separation equipment that uses the principle of screw extrusion, through the strong extrusion force generated by the change of screw diameter and pitch, as well as the tiny gap between the moving ring and the fixed ring.

construction principle

The main body of the stacked screw sludge dewatering machine is a filtering device formed by multiple fixed rings and moving rings, and the screw shaft penetrates through them. The front section is the concentration section and the back section is the dehydration section. The sludge concentration and squeezing dehydration are completed in one cylinder, replacing the traditional filter cloth and centrifugal filtration mode with a special filter body mode.

Dehydration principle

After the sludge is concentrated by gravity in the concentration section, it is transported to the dehydration section. In the process of advancing, with the gradual decrease of the filter seam and the pitch, and under the blocking effect of the back pressure plate, great pressure is generated, and the volume is continuously reduced., To achieve the purpose of full dehydration.

Note: The replacement time of wearing parts is an approximate value. In the actual operation process, the nature of sludge, operation and maintenance management and operation time will affect the replacement cycle of wearing parts. (The replacement cycle of wearing parts is calculated by 365 days/year and 10 hours/day running time)
