Online high-pressure water-jet blasting surface cleaning system

Abstract

An online high-pressure water-jet blasting surface cleaning system comprises a high pressure water feed mechanism, an abrasive material feed mechanism and a spray nozzle. The high pressure water feed mechanism and the abrasive material feed mechanism are communicated with an input end of the spray nozzle, an abrasive material collecting pit is arranged below the spray nozzle, an output end of the abrasive material collecting pit is divided into two paths, one path is connected with an input end of an abrasive material sorting device by an abrasive material cyclical feeding device and a pipeline, and the other path is connected with an input end of a waste water treatment circulating mechanism by a pipeline, an output end of the waste water treatment circulating mechanism is connected with the high pressure water feed mechanism by a pipeline, an output end of the abrasive material sorting device is divided into two paths, one path is connected with the abrasive material feed mechanism, and the other path is connected with a slag collection barrel by a pipeline. The online high-pressure water-jet blasting surface cleaning system has the advantages of simple and compact structure, low energy consumption, good environmental protection, good operational reliability and stability, and recycled water and abrasive materials.

Description

technical field [0001] The invention mainly relates to the field of metal surface cleaning equipment, in particular to an online high-pressure water jet sandblasting surface cleaning system for cleaning metal surface oxides, paint or solid surface dirt. Background technique [0002] Metal surface cleaning technology is an indispensable process before the metal is subjected to surface coating, heat treatment, machining and cold rolling. The quality of metal surface cleaning directly affects the quality of metal surface coating and mechanical product quality. Traditional surface cleaning mainly includes manual cleaning, mechanical cleaning, chemical cleaning, electronic cleaning, flame cleaning and spray cleaning, among which spray cleaning is more commonly used. [0003] Jet cleaning uses mechanical centrifugal force or compressed air or high-pressure water as the power to accelerate the abrasive through a special nozzle. The abrasive is sprayed to the metal surface at a hig...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantages of the above-mentioned high-pressure water jet sandblasting cleaning system are: the system is open, the water is not recycled, the abrasive is not automatically recovered, and the abrasive is supplied under pressure, the structure is complicated, and the system pipeline is severely worn; Uniform, and the abrasive supply pipeline is easy to block, the cleaning quality is poor in consistency, and it is difficult to be used for online cleaning
