Description

Technical Field

[0001] The utility model relates to the technical field of polishing and grinding equipment for chemical containers, in particular to a polishing and grinding device for chemical pressure containers. Background Art

[0002] Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. Pressure vessels are widely used. They play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, they are most widely used in the chemical industry and petrochemical industry. Pressure vessels generally consist of six parts: cylinder, head, flange, sealing element, pipe and support. During the production of pressure vessels, two heads are usually welded to the two ends of the cylinder. After welding, there will be a weld nodule formed at the joint between the head and the cylinder. The weld nodule is very uneven. Therefore, it is necessary to use a polishing and grinding device to grind the weld nodule at the joint between the head and the cylinder.
