Abrasive recovery device in abrasive water jet descaling system

Abstract

The invention discloses an abrasive recovery device in an abrasive water jet descaling system, which comprises a mixing bucket connected with a recovery bucket, a cyclone separator and a sediment pool; the recovery bucket and the cyclone separator have corresponding stages , there are vertical slurry pumps in the recovery barrels at all levels, the inlets of the cyclone separators at all levels are connected to the outlets of the corresponding vertical slurry pumps, and the outlets of the abrasive liquid at the bottom of the cyclone separators at all levels are connected to the mixing tank, and finally The overflow port of the first-stage cyclone separator leads to the sediment pool, and the overflow ports of the other stages of cyclone separators return to the recovery barrel of the same stage. Through the setting of multi-stage recovery barrels and cyclone separation, the internal circulation channel of the abrasive liquid is created, and the dynamic balance of the abrasive liquid in the recovery device is established, which can realize efficient step-by-step separation and recycling of the abrasive liquid after descaling as required. of abrasives. It has the advantages of safe, stable and reliable work, and the whole process adopts automatic control, which has wide 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
