Sand blasting rust removal device

Abstract

The invention relates to the field of sand-blast cleaning technologies and processing, and in particular relates to a sand blasting rust removal device. The sand blasting rust removal device comprises a sand blasting cabin body, a driving mechanism, a transmission mechanism, a conveying device and a dust removal device, wherein the sand blasting cabin body is connected with an external electric control system; the conveying device is used for conveying a workpiece; the dust removal device is used for removing dust; the sand blasting cabin body comprises a sand blasting cabin; a sand blasting device is arranged in the sand blasting cabin; a pellet collecting device is arranged at the bottom of the sand blasting cabin body; the conveying device runs through the sand blasting cabin body; the driving mechanism is connected with the transmission mechanism and drives the transmission mechanism to rotate to drive the sand blasting device to move in the conveying direction of the workpiece; the dust removal device is connected with the sand blasting cabin body through a pipeline. According to the sand blasting rust removal device, the workpiece is driven to move into the sand blasting cabin through the belt conveying device; under the driving action of the driving device, a spraying gun is driven by the transmission of the transmission mechanism to uniformly spray sands to the workpiece, so that rust on the surface of the workpiece is effectively removed, and the sand blasting rust removal device is low in rust removal cost, stable in quality, high in working efficiency, environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical processing field of sand blasting, in particular to a sand blasting rust removal device. Background technique [0002] The principle of sandblasting surface treatment is to spray abrasives onto the surface of the workpiece for impact grinding, remove impurities, variegated colors and oxide layers on the surface, and at the same time roughen the surface of the medium to increase the surface area, so that the adhesion of the coating can be improved , so that the coating has the strongest acid and alkali resistance, improves the coating quality, and at the same time plays a role in reducing the residual stress on the surface of the substrate, improving the surface hardness of the substrate and meeting the requirements of surface decoration. Industrial and civil liquids and gases are mainly transported by metal pipelines. Because the corrosiveness of liquids and gases corrodes the inner wall of the pipeline, it is eas...

AI Technical Summary

Problems solved by technology

The chemical pickling method not only has high processing costs, unstable rust removal quality, serious pollution, harsh production environment, and great health hazards to operators. At the same time, the surface roughness required for coating an anti-corrosion protective layer cannot be formed after rust removal. thus affecting the coating quality

The mechanical cleaning method not only has a large manual workload and labor intensity, but also has low work efficiency. For the batch production of small workpieces, the mechanical cleaning method is even more unsuitable.
