Special shot blasting machine for outer wall of steel pipe

Application

 QG series special shot blasting machine for the outer wall of steel pipe is used for shot blasting treatment of the outer surface of steel pipe and steel pipe products, removing the oxide layer and welding slag, showing a metallic luster, increasing its specific surface area, in order to facilitate the painting and painting of the workpiece.

Features: The shot blasting device is arranged in a suitable position (such as below or on the side of the chamber), and the workpiece is rotated while entering, which can make the shot blasting effect of different pipe diameters be consistent.

Introduction

Protection of the chamber body

The interior of the chamber is protected by a wear-resistant protective plate. The protection plates are pressed with protective nuts for easy disassembly and replacement.

Sealing of steel pipe inlet and outlet

In view of the specific characteristics of the workpiece to be cleaned, the shot blasting machine is designed with a chamber door for quick interchange. When cleaning the large diameter of the workpiece, replace the big mouth of the door; When cleaning the small diameter of the workpiece, replace the small diameter of the door, so that it can be well sealed.

Work drive mechanism

This type of shot blasting machine can be equipped with a variety of workpiece driving mechanisms, such as rubber wheel, V-shaped inclined roller table, etc.

Blasting wheels

The position of the shot blasting device in the chamber body (such as the bottom, side or slope) can make the workpiece of different pipe diameters be well cleaned.

shots circulation purification system

Shot blasting machine adopts full curtain type shot sand separator. The separator is composed of a separator spiral, a drum screen, a separating area, a pellet bin, etc. A feeding port is provided at the funnel of the pellet sand separator for replenishment of new pellets to the equipment.

Dust removal system

The dust removal system is used to remove the dust generated in the working process of the shot blasting machine to prevent environmental pollution. The system consists of dust collector, fan and connecting pipe (from cleaning room, separator to dust collector). The connecting pipe is equipped with a butterfly valve, which is used to adjust the air volume, so that the work of each part of the equipment can achieve a better state, so that there is no dust overflow during the working process.

Another form of steel pipe wall blasting machine. Two blasting wheels are arranged in the upper part of the shot blasting chamber body, and the work piece rotates while passing through the shot blasting chamber.
