AI Technical Summary

Technical Problem

Existing sludge pipelines are prone to scaling and blockage due to the deposition of sludge or impurities, causing production stoppages and a large amount of maintenance work.

Method used

An elastic spiral body aligned with the flow direction of the medium is installed inside the sludge pipeline. It is rotated by a drive mechanism to prevent impurities and sludge from depositing. Combined with a PTFE wear-resistant layer and a sealing structure, it ensures rotational stability and wear resistance.

Benefits of technology

It effectively prevents impurities and sludge from depositing and forming scale in the pipeline, avoiding accidents and maintenance time caused by scale blockage, ensuring normal production, adapting to pipeline elbow structures and possessing acid and alkali corrosion resistance.

Abstract

The utility model provides a sludge pipeline capable of preventing scaling and blocking. The sludge pipeline comprises a sludge pipeline, an elastic spiral body and a driving mechanism, the sludge pipeline is provided with a slurry inlet and a slurry outlet; the elastic spiral body is coaxially arranged in the sludge pipeline, and the outer diameter of the elastic spiral body is smaller than the inner diameter of the sludge pipeline; the driving mechanism is connected with the two ends of the elastic spiral body through the rotor and used for driving the elastic spiral body to rotate at a constant speed in the sludge pipeline. And the spiral direction of the elastic spiral body is consistent with the flowing direction of a medium in the sludge pipeline. According to the utility model, the elastic spiral body which is consistent with the flowing direction of a medium is arranged in the sludge pipeline, and slurry is stirred and disturbed through rotation of the elastic spiral body, so that deposition and scaling of impurities and slurry in the pipeline are effectively prevented, and the pipeline is prevented from being scaled and blocked; the design that the outer diameter of the elastic spiral body is slightly smaller than the inner diameter of the sludge pipeline ensures that the elastic spiral body can smoothly rotate in the pipeline; due to the elastic bending characteristic of the elastic spiral body, the elastic spiral body can adapt to a pipeline elbow structure.
