Description

Technical Field

[0001] The invention relates to the technical field of shot blasting conveying, in particular to a pneumatic shot blasting conveying device. Background Art

[0002] Shot blasting is a processing technology that uses a shot blaster to throw steel shots at high speed and impact on the surface of a material object. Compared with other surface treatment technologies, it is faster and more effective, and can be used to process partially retained or stamped casting processes. The working principle of the shot blasting machine is to use a high-speed rotating impeller to accelerate the projectile to several times the acceleration of gravity, and then guide the projectile in a certain direction through the separator blades, so that the marbles shot at the workpiece contact and impact with the high-speed moving steel sand to achieve the purpose of removing the surface of the workpiece. The projectile can also be called shot blasting steel ball.

[0003] The diameter of the shot blasting steel ball usually ranges from 0.2 mm to 3 mm, and different application scenarios may use shot blasting steel balls of different sizes. The pipelines of pneumatic conveying are ever-changing, but generally materials are transported from one or more feeding points to one or more target points through vertical, horizontal or inclined pipelines. The conveying process is safe, continuous and pollution-free; the modes of conveying are dilute phase conveying and dense phase conveying. At present, the size of the conveyed materials of most pneumatic conveying systems is generally less than 10 mm. General pneumatic conveying equipment requires the pipeline to be arranged on the ground so that personnel can promptly find the damaged position of the conveying pipeline and carry out repair operations. However, some plant areas are limited by the layout of the plant area and require the pipelines of the conveying system to be buried underground. At this time, once the underground pipeline is damaged, personnel cannot find the damaged point in time and cannot quickly carry out repair operations, making it difficult for the equipment to continue the conveying operation in a short time, seriously affecting the subsequent processing operations.

The discharge structure 5 releases the shot blasting steel balls into the manifold 4. The fan 2 blows the pressure pump 3, and the pressure pump 3 pressurizes the airflow, so that the pressure pump 3 inputs high-speed and high-pressure airflow to the manifold 4, so that the shot blasting steel balls are blown into the guide pipe 6 by the high-pressure airflow to carry out the shot blasting steel ball conveying operation. When the guide pipe 6 covered by the protection pipe 7 is damaged, the first air pressure detection probe 8 detects that the protection pipe 7 is damaged.
