Abstract

A control method of a sludge treatment system includes a sludge feeding control method, a centrifugal control method and a discharging conveying control method. The discharging conveying control method includes: when the whole system is under a shutdown condition, closing a first gate plate and a second gate plate; in an operating state, opening the first gate plate first, and then closing the second gate plate, so that sludge is thrown to a sludge bearing arc wall and accumulated above the second gate plate to relieve discharging impact; opening the second gate plate to allow sludge to fall on a conveying belt, so that piles of sludge are formed on the conveying belts and relatively concentrated to make it convenient for subsequent collection.

Description

technical field

[0001] The invention relates to the related field of mud treatment, in particular to a control method of a mud treatment system. Background technique

[0002] With the development of science and technology and economic development, the amount of mud used is increasing. At present, the mud in the city mainly comes from construction engineering mud, municipal sludge and river silt. With the continuous acceleration of urbanization, high-rise, super There are more and more constructions of various projects such as high-rise buildings, subways, expressways, and large bridges, and the amount of mud produced is also increasing. At present, there are mainly the following ways to deal with mud: 1) Tanker truck (mud truck) for external transportation. This method is to directly lift the mud generated on site into the mud truck through the mud pump, and transport the mud to the outskirts of the city through the mud truck. 2) On-site sedimentation and drying, this metho...
