Control method of sludge treatment system

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...

AI Technical Summary

Problems solved by technology

[0004] 1. The outer cylinder of the centrifuge in the prior art needs to be larger in size, because the outer cylinder contains relatively solid mud and needs to be discharged, and there is a waste of space, but the diameter of the outer cylinder cannot be reduced because of the reduction. It is not enough to accommodate a large number of mud parts, so it causes troubles. The solution is often to directly use a large-diameter outer cylinder, but it does not meet the design trend of miniaturization and refinement

[0005] 2. The centrifuge in the prior art lacks maintenance means, and only part of it can be cleaned during cleaning, and there is a cleaning dead angle

[0006] 3. A part of the centrifuge in the prior art is provided with a drain pipe or a liquid collecting pipe, which is often exposed in the drum and is washed by centrifugal particles. When there are stones in the mud, it is easy to rotate and damage the drain pipe; for this reason The solution is often to increase the material hardness of the discharge pipe, but it increases the cost

[0007] 4. There is a discharge valve under the centrifuge in the prior art, but the discharge valve is directly impacted by the centrifuged material, and it is easy to loosen or even be damaged after a long time

[0008] 5. After the centrifuge in the prior art is used for a long time, it will accumulate materials that are difficult to remove, even if it is impacted by water, it cannot be removed

[0009] 6. In the mud treatment system of the prior art, when the conveyor belt is conveying, the material is often randomly dropped onto the conveyor belt, which is uncontrollable, and there is difficulty in collecting the random material.
