Embodiment

[0028] Embodiment: When in use, air-dry or sun-dry the pipeline sludge, and use a mill to grind it into powder, and the powder particle size is 1-3mm. The sludge powder is input into the top of the vibrating screen 4 on the water tank 3. With the vibration of the vibrating screen 4, the sludge with small particle size enters the water tank 3, and the large-sized sludge particles enter the hopper 12 and are sent back to the sludge through the conveyor belt 13 The pool 1 is lifted and filtered again; the sludge entering the water tank 3 enters the water, and the water is treated to make part of the suspended matter and floating matter; Excluded, the excluded suspended matter enters the solid-liquid separator 16 for solid-liquid separation, the generated waste residue enters the waste residue bucket 17, and the generated water flows back to the water tank 3 through the return pipe to continue to use; the sludge filtered by the filter screen 5 settles to the bottom of the water , ...

Abstract

The invention discloses a hydraulic separation method used for pipeline sludge, and a system thereof. The method comprises the following steps: large-particle size particles are separated from ground sludge powder by adopting a vibration screen, and small-particle size particles obtained after vibration screening are added to water; the small-particle size particles in water are processed with water to generate parts of suspending substances and floating substances; the suspending substances downward settle and are filtered through a filter screen, and the floating substances are eliminated through a water draining tube; the suspending substances filtered through the filter screen settle to the bottom of water, and the obtained precipitate is sent to a sand removal device through a pump, and undergoes sand removal; cyclone sand removed isolate falls to a sand barrel and is stored, and separated water is used in flushing after being filtered; and the floating substances go through a pipeline, enter a solid-liquid separator, and are separated, and superfluous sludge on the vibrating screen is recovered, and then goes through the vibration screen. The method and the system have the advantages of great saving of water resource consumption, increase of the treatment efficiency, prevention of artificial contact with sludge, and effective improvement of the safety effect.

Description

technical field [0001] The invention relates to the technical field of processing building materials, in particular to the technical field of sludge separation, and in particular to a hydraulic separation method and system for pipeline sludge. Background technique [0002] Pipeline sludge is a part of rainwater and sewage that is easily settled during pipeline transportation and gradually accumulates in the pipeline. It is mainly composed of sand, gravel, and a small amount of organic matter. It can be used as an auxiliary raw material for building materials. For waste utilization, but at the same time, the pipeline sludge also accumulates a large amount of heavy metals, pathogenic microorganisms, etc. If it is not properly treated, it will not only cause secondary pollution to the environment, but also pose a great threat to human health. Mainly, it is mixed with a large amount of household garbage, bark, masonry and other sundries, which brings great difficulties to the tr...
