An automatic sandblasting device and sandblasting method

Abstract

The invention provides a device capable of realizing automatic sand blasting and a sand blasting method thereof. The automatic sandblasting device and sandblasting method provided by the invention can improve the safety of operation. In the actual sandblasting and rust removal, unmanned operation can be realized in the sandblasting room, and there is no potential safety hazard for personnel; in addition, the automatic sandblasting provided by the invention The device and sandblasting method have high efficiency, uniform rust removal, more accurate positioning, better and more uniform effect; moreover, the automatic sandblasting device and sandblasting method provided by the invention can be used for 24-hour construction, getting rid of the technical proficiency of people It can greatly improve work efficiency, reduce labor intensity and labor cost, and is suitable for industrial promotion.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an automatic sand blasting device and a sand blasting method thereof. Background technique [0002] The heat exchanger tube bundle is generally composed of seamless steel pipes with an outer diameter of 25mm or 19mm, ranging from one to two hundred to as many as four to five thousand. In actual work, each tube bundle must be blasted and derusted at its two ends. At present, artificial sandblasting is mainly used to remove rust one by one. There are several problems. One is unsafe. Spraying on the body will cause injury. Equipment with a large diameter needs to be sandblasted from a height. During the sandblasting process, the visibility in the sand room is extremely low, and there is a danger of falling from a high altitude. The second is that the manual labor intensity is high, the efficiency is low, and the rust removal is uneven. The high-speed airflow from the spray gun hits the n...

AI Technical Summary

Problems solved by technology

At present, artificial sandblasting is mainly used to remove rust one by one. There are several problems. One is unsafe. Spraying on the body will cause injury. Equipment with a large diameter needs to be sandblasted from a height. During the sandblasting process, the visibility in the sand room is extremely low, and there is a danger of falling from a high altitude.

Second, the manual labor intensity is high, the efficiency is low, and the rust removal is uneven

The high-speed airflow from the spray gun hits the nozzle to form a huge reaction force. It is necessary to hold the gun head tightly to perform sandblasting, and the nozzle of the sandblasting gun must be aimed at the thinner nozzle and keep basically the same distance from each nozzle. In order to achieve uniform and optimal rust removal effect, workers are prone to fatigue and cannot keep consistent movements. The rust removal effect is good and bad, and it needs to be compensated, which is a waste of time.

The third is that the body is seriously damaged. Although there are dust removal equipment and labor protection measures, it cannot prevent the dust from harming the body.
