Combined type centrifugal sludge dewatering machine

Abstract

The invention discloses a combined type centrifugal sludge dewatering machine which comprises a centrifugal dewatering mechanism, a screw dewatering mechanism and a heating device, wherein the centrifugal dewatering mechanism comprises a centrifugal barrel, a driving shaft sleeve and a motor; the screw dewatering mechanism comprises a screw dewatering barrel and a screw conveyer; the driving shaftsleeve is arranged in the rotating center of the upper end part of the centrifugal barrel; the driving shaft sleeve is sleeved on the outer side wall of a sludge feeding hopper; the bottom of the centrifugal barrel is in an open type structure, which is communicated with the screw dewatering barrel; the end part of the screw conveyer is connected with the bottom of the centrifugal barrel by a transmission part; a sludge outlet is formed in the bottom of the screw dewatering barrel; the heating device is mounted at the sludge outlet; a shell is sleeved on the outer wall of the centrifugal barrel and the screw dewatering barrel; a drain pipe is arranged at the bottom of the shell. A centrifugal dewatering manner is combined with a propulsion mechanism, and a matched design that ventilationtemperature control is combined with the heating device is adopted, so that the combined type centrifugal sludge dewatering machine is simple in structure and convenient in operation and is good in dewatering effect under a certain energy consumption, therefore, the combined type centrifugal sludge dewatering machine is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a compound centrifugal sludge dehydrator. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. Untreated sludge entering the environment will directly bring secondary pollution to water bodies and the atmosphere, and it will also affect the ecological environment and human activities. would pose a serious threat. Therefore, the treatment of sludge is very cautious, and the treatment of sludge can be divided into two types: sludge dehydration process and sludge drying process. [0003] Sludge dewatering machine is a kind of sludge treatment equipment with continuous operation. Because of its low moisture content in sludge, stable operation, low energy consumption, relatively simple control and management, and convenient maintenance, it has been widely used in industrial, mining, and sewage treat...

AI Technical Summary

Problems solved by technology

[0008] Although the sludge dewatering machine has various forms, it still has the problems of poor dehydration effect and high energy consumption. Therefore, in order to promote the development of sewage treatment, its related equipment needs to be further improved and perfected.
