Pressure vessel machining method and polishing device for machining of pressure vessel

Abstract

The invention discloses a polishing device for pressure vessel machining, which comprises a polishing device body, the polishing device body comprises a base for placing a pressure vessel, the base is provided with a rotating disc, the pressure vessel is placed on the rotating disc, and the rotating disc drives the pressure vessel to rotate; the lifting device is arranged on the base and comprises a plurality of lifting rods which surround the periphery of the pressure container and are vertically arranged; the surrounding device is arranged on the lifting rod, the surrounding device comprises a fixing ring and a sliding block arranged on the fixing ring, the sliding block annularly moves along the fixed surrounding pressure container, and the fixing ring ascends and descends along the pressure container through the lifting device; the grinding device is arranged on the sliding block and used for grinding the pressure container, and the grinding device annularly moves along the pressure container through the surrounding device; the spraying device is arranged on the sliding block and used for spraying rust removal liquid; and the cleaning device is arranged on the spraying device and used for cleaning the spraying device.

Description

technical field [0001] The invention belongs to the technical field of pressure vessels, and in particular relates to a pressure vessel processing method and a grinding device for processing thereof. Background technique [0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. In order to more effectively implement scientific management and safety supervision and inspection, my country's "Pressure Vessel Safety Supervision Regulations" divides pressure vessels into three categories according to working pressure, medium hazards and their role in production. [0003] A pressure vessel is a closed container that can withstand pressure. The pressure vessel has a wide range of uses, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, the most used ones are in the chemical industry and the petrochemical industry, and the pressure vess...

AI Technical Summary

Problems solved by technology

The invention provides a method for processing chemical pressure vessels, which can solve the following problems in the process of processing chemical pressure vessels: a. The chemical pressure vessel has a plate-shaped bending to form a cylinder, and its interface is welded and sealed by welding , so that welding slag will be produced at the welding place, that is, the welding place needs to be polished to remove the welding slag; b. In the current traditional method, most of the welding places are manually sanded and polished by a grinder, which is labor-intensive. Low work efficiency, especially for grinding the welds on the inner wall of chemical pressure vessels; c. The grinding devices currently in the market have complex structures, are expensive, and have single functions and effects, and can only be aimed at a certain specification, making their practical value not high

[0006] However, there are still problems in the above-mentioned patent: the above-mentioned grinding device does not process the flying dust and welding slag generated by grinding, which will pollute the processing environment and easily affect the human health of the staff
