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. It can only clean part of it during cleaning, and there is a cleaning dead angle. A part of the centrifuge is provided with a drain pipe or a liquid collection 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 discharge pipe; the solution for this is often to increase the material hardness of the discharge pipe, but it increases the cost
[0006] 3. 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
[0007] 4. 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.

Abstract

The invention discloses a control method for a slurry treatment system. The control method comprises the steps that a control valve is connected between a feeding and closing barrel and a centrifugalmachine; in the initial state, the control valve is closed, a mud pump conveys mud in the mud pit to the a barrel; a flocculating agent pump conveys a flocculating agent to the mixing barrel; a mixingbarrel motor drives blades in the mixing barrel to stir; after the uniform stirring, the control valve is opened, mud enters the centrifugal machine through the mud inlet pipe, the mud is thrown to the mud bearing arc-shaped wall and accumulated above a second gate plate, falling impact is relieved through the accumulated mud, then a second gate plate is opened, the mud falls onto the conveying belt, and thus the accumulated mud is formed on the conveying belt and is relatively concentrated to facilitate subsequent collection.

Description

technical field [0001] The invention relates to the related field of mud treatment, in particular to a control method for a mud treatment system. Background technique [0002] At present, the mud in the city mainly comes from construction mud, municipal sludge and river silt. With the continuous acceleration of urbanization, the construction of high-rise, super high-rise buildings, subways, expressways, large bridges and other projects is becoming more and more More and more, the amount of mud produced is also increasing. At present, the treatment methods of mud mainly include centrifugal dehydration, and a centrifuge can be used to dehydrate construction mud. [0003] For the third method "centrifugal dehydration". In actual use, there are the following problems: [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, b...
