Abrasive recovery device in abrasive water jet scale removal system

Abstract

The invention discloses an abrasive recovery device in an abrasive water jet scale removal system. The abrasive recovery device comprises a stirring barrel, wherein recovery barrels, cyclone separators and a detritus tank are connected at the back of the stirring barrel; a plurality of corresponding stages of recovery barrels and cyclone separators are provided; each stage of recovery barrel is internally provided with a vertical slurry pump; the inlet of each stage of cyclone separator is communicated with the outlet of the corresponding vertical slurry pump; the abrasive liquid outlet at the bottom of each stage of cyclone separator is communicated with the stirring barrel; the overflow port of the last stage of cyclone separator is communicated with the detritus tank; overflow ports of the remaining stages of cyclone separators are returned to the corresponding stage of recovery barrel. The plurality of stages of recovery barrels and cyclone separators are arranged, so that the interior circulating path of abrasive liquid is created, dynamic balance of the abrasive liquid in the recovery device is established, and the recyclable abrasive in the abrasive liquid after scale removal can be separated and recycled efficiently and progressively according to requirements. The abrasive recovery device has the advantages of being safe, stable and reliable to work, automated for control during the whole process and wide in applicability.

Description

technical field [0001] The invention relates to an abrasive recycling device in an abrasive water jet descaling system. Background technique [0002] Before deep processing of steel (such as cold rolling, cold drawing, etc.), it is necessary to remove the dense oxide layer attached to the surface—commonly known as "scale skin". Because of the existence of these scales, on the one hand, it will be difficult to detect the cracks on the steel surface in time, resulting in secondary deep processing quality problems; on the other hand, it is easy to press the scales into the metal surface during subsequent deep processing, causing surface quality problems; The presence of scales accelerates the wear of rolls or drawing machines. [0003] Abrasive water jet descaling technology is a high-tech developed in modern times. It has the advantages of high descaling efficiency, no waste acid, waste water discharge, environmental protection, energy saving, low cost of use, and no anti-cor...

AI Technical Summary

Problems solved by technology

The advantage of the pre-mixing abrasive water jet is that the abrasive particles are mixed evenly and the working pressure is low. However, due to the limitations of the pre-mixing wearing parts, such as low service life and inability to operate continuously, its application in the field of industrial steel descaling is restricted.

At present, post-mixing abrasive water jet descaling equipment is mostly used in domestic industrial production, but an efficient abrasive recovery device has not been proposed in the post-mixing abrasive water jet descaling system
