Concentrating, dewatering and strong-pressure integrated sludge dewatering machine

Abstract

The invention discloses a concentrating, dewatering and strong-pressing integrated sludge dewatering machine which comprises a rack, and further comprises a gravity filtering mechanism, a vertical rolling dewatering mechanism and a counter-pressing type dewatering mechanism which are sequentially arranged on the rack, the gravity filtering mechanism comprises a filtering device, a bottom frame assembly, a side leakage preventing assembly, a mud overturning assembly and a thickness adjusting assembly; the vertical rolling dehydration mechanism comprises an S-shaped dehydration section, the S-shaped dehydration section is located at the downstream of a slurry outlet, the S-shaped dehydration section comprises a plurality of dehydration rollers which are rotatably connected to the rack and are integrally arranged from bottom to top, and the outer diameters of the dehydration rollers are gradually decreased to the minimum outer diameter from the upstream to the downstream; the counter-pressing type dewatering mechanism comprises a strong pressing section, a strong pressing roller set is arranged on the strong pressing section, and the strong pressing roller set comprises a fixed rollerset and a movable roller set. The gravity filtering mechanism, the vertical rolling dewatering mechanism and the counter-pressure type dewatering mechanism are arranged to form the sludge dewateringmachine which is large in treatment flux, high in water filtering capacity and high in treatment precision.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a thickening, dewatering, and high-pressure integrated sludge dewatering machine. Background technique [0002] Both domestic sewage treatment and industrial sewage treatment will produce a large amount of sludge. The treatment and disposal of sludge is an extremely important link in the water treatment process. If it is not handled properly, it will cause secondary pollution to the environment. The existing more practical sludge disposal methods, such as incineration, composting, solidification and backfilling, etc., all require deep dehydration of sludge. The national standard requires that the moisture content of the sludge discharged from domestic sewage treatment plants be reduced to below 60%. The existing process generally uses the addition of deep dehydration agents for conditioning, and then presses through a high-pressure diaphragm filter press. Due to the shortcomings...

AI Technical Summary

Problems solved by technology

Due to the intermittent work of the high-pressure diaphragm filter press, small processing flux, weak water filtration ability, and low processing accuracy, there is an urgent need for a pressing equipment with large processing flux, strong water filtration ability, and high processing accuracy.
