Stacked screw type sludge dewatering machine for industrial wastewater treatment

Abstract

The invention relates to the technical field of environmental protection, and discloses a stacked screw type sludge dewatering machine for industrial wastewater treatment. The stacked screw type sludge dewatering machine comprises a motor assembly, wherein one end of the motor assembly is fixedly connected with a back pressure plate assembly, one end of the back pressure plate assembly is fixedly connected with a machine shell, the bottom end of the back pressure plate assembly is fixedly connected with a sludge outlet, one end of the machine shell is fixedly connected with a sludge inlet, one output end of the motor assembly is fixedly connected with a rotating shaft in a sleeved mode, the rotating shaft is fixedly connected with spiral blades, and the upper end and the lower end of the center of the inner cavity of the machine shell are connected with symmetrical positioning rods through bolts. Through the designed floating rings and the offset protrusions on the driving rod, the two adjacent floating rings of the concentration part can be driven by the offset protrusions to complete relative cross movement, a larger shearing effect is formed, the self-cleaning capacity of a filter seam is enhanced, and the water precipitation efficiency is improved while the contact between the floating rings and spiral blades is avoided, so that the abrasion of the spiral blade is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a screw-stacked sludge dehydrator for industrial wastewater treatment. Background technique [0002] After industrial wastewater is treated, sludge thick liquid with high water content often remains. If this sludge thick liquid is discharged directly without subsequent treatment, it will pollute the soil and the atmosphere. The sludge currently used Dewatering device, plate and frame sludge dewatering machine, belt sludge dewatering machine, centrifugal sludge dewatering machine and stacking screw sludge dewatering machine, among which stacking screw sludge dewatering machine gradually occupies the sewage due to its good dewatering effect Important position for mud dehydration. [0003] The working principle of the stacked screw sludge dewatering machine is that the fixed ring and the moving ring are interlaced to form a stacked layer. The screw shaft runs throu...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the use of the existing screw-stack sludge dewatering device proposed in the background technology, the present invention provides a screw-stack sludge dewaterer for industrial wastewater treatment, which is equipped with no fixed ring and a thickening part filter seam The advantages of strong self-cleaning ability, fast water analysis, small screw shaft wear, and no sludge clogging device solve the technical problems raised in the above background technology
