Description

Technical Field

[0001] The invention relates to the technical field of container processing, and in particular to a processing device for a chemical pressure container. Background Art

[0002] Chemical pressure vessels are used to store and transport chemical products, such as liquids and gases, and are widely used in petrochemical, pharmaceutical, food processing and other industrial fields. Most common ones are storage tanks with smooth inner walls, generally made of metals such as steel, which have both corrosion resistance and high strength. Its welding processing equipment can weld components or parts together to ensure that the container is pressure-resistant, corrosion-resistant, and sealed. It can use submerged arc, gas shielded, resistance and other welding processes to ensure welding quality and safety to meet the requirements of use.

[0003] In the processing equipment of a chemical pressure vessel disclosed in the patent publication number "CN118321691B", a measuring rod is slidably fitted with one side of two chemical containers to control and adjust the welding flux discharge amount of the buried material port on the submerged arc welding gun, and the welding head adjusts the welding power at the same time. Although it can prevent the situation that when the gap of the chemical container is too small or too large during welding, more discharge will cause waste of welding flux, and when the discharge is small, the welding quality will be reduced. However, in actual use, before welding, burrs on the welding contact surface of the container will directly affect the welding effect, resulting in defects such as unevenness and inclusions in the weld. In addition, when the welding is completed, the welding slag, spatter and welding aids that have not been completely volatilized left on the surface of the container will greatly affect the appearance neatness of the container.

[0004] Based on this, the present application proposes a processing equipment for chemical pressure vessels. Summary of the invention

When the rack is reset, it will drive the piston to generate negative pressure in the piston cylinder. Under the action of the one-way valve, the water in the water tank enters the piston cylinder to prepare for the next cooling. BRIEF DESCRIPTION OF THE DRAWINGS
